Pros or cons of multiple cigarette lighters

Old cars, for example, the classic VAZ, have a different device design. There is a long cigarette lighter with its pros and cons. This device has been developed for a long time, so it has a number of technological shortcomings. The disadvantages include:

Inability to connect multiple devices to the cigarette lighter.
Weak contacts. Over time, due to age or frequent driving on rough roads, the antennae of the cigarette lighter itself may become loose. This disrupts the operation of the device and can lead to its failure.
The disadvantages include the appearance of the old cigarette lighter, which is much worse. The light bulb does not shine as brightly or often burns out.

New car models are equipped with a modern European cigarette lighter with a large seat. To install it on a classic, you will need to drill out the socket, purchase a special three-pin connection plug and solder the wires.

But this modification of the cigarette lighter has a number of advantages.

Reliable contacts. The European cigarette lighter holds well in the socket, and the fixing nut does not unscrew.
Plus - the appearance, the backlight is prettier.
A modern car cigarette lighter allows you to connect several devices at the same time.

Therefore, when purchasing a device for a car, it is better to choose the second option.

Car cigarette lighter polarity

Sometimes an element fails. Frequent malfunctions are as follows.

Blown fuse. A special protective element is installed on the electrical circuit, designed for a current of 10 Amps. When a malfunction or short circuit occurs, it burns out to keep the cigarette lighter, wires and instruments working. This element is responsible for several more devices. If the cigarette lighter and the clock do not work, then you should get to the mounting block and replace the fuse.
Oxidized contacts. Over time or from connecting powerful devices to the cigarette lighter (such as a compressor or car charger), the metal connectors can oxidize. Before replacing, it is advisable to remove the cartridge and inspect the antennae for the appearance of oxides. If there are such moments, they should be cleaned and bent for a better connection. Before carrying out the procedure, it is recommended to remove the negative terminal from the car battery. This will prevent a short circuit. You need to know where the plus and minus are.
Waste car cigarette lighter incandescent element. The nichrome spiral located inside the cartridge can also burn out. This will entail installing a new cigarette lighter.
Short circuit or broken wiring. Cables may fray or melt as a result of shortening. You can determine such a malfunction of the car cigarette lighter using a multitester. It is necessary to check the integrity of the wires.

Correct connection of the cigarette lighter

You can repair a car device, dismantle it or install it yourself. To replace the cigarette lighter you will need the following list of tools:

Phillips/minus screwdriver;
blowtorch with solder;
connecting terminals for plus and minus.

Repair is carried out as follows.

We dismantle the car cigarette lighter. It is removed differently in each car. Sometimes you just need to pry the cartridge, and sometimes you have to remove the lining of the central tunnel.
We disassemble the car cigarette lighter. We find the semiconductor wafer at the bottom. This is what often causes breakdowns. Let's delete it.
We cut off the protrusion on the outer casing.
We assemble the cigarette lighter in the reverse order of disassembly.
We strip the connection wires at least 5 mm.
We connect the car cigarette lighter wires, observing the polarity, where is positive and where is minus. You can use a blowtorch or a special terminal block and clamps.
We dismantle the center console for reverse connection.
Disconnect the backlight unit.
We stretch the wires and then connect them to the car cigarette lighter connector.
We carry out the assembly process in reverse order.

Pinout and desoldering information

The cigarette lighter device can be seen in the photo. At the end of the part there is a contact terminal. Inside there are special holders, a heating element and a cup. There are connector tabs and a return spring. And for safety from burns there is a special insulator. All this is protected by a plastic case.

A detailed diagram of the pinout and wiring of the cigarette lighter wires is presented in the video.

Cigarette lighter plug connection diagram

Before installing a new part, you need to understand the polarity. You can understand where the plus and where the minus is on the cigarette lighter by looking at the photo.

There are three different wires going to the device.

Red goes into the battery and is responsible for additional devices such as a watch.
The yellow one, central, also goes to the battery. This is the socket light bulb.
Black side – minus, mass. Located on the body of the part.

When the device needs to be replaced, it should be connected according to the diagram shown in the photo.

Where is the cigarette lighter fuse located?

A burnt-out protective element may be the result of connecting one powerful device or several devices to the socket. Because of this, the current strength in the wires exceeds a critical value, as a result of which the fuse melts. This may happen because the owner has confused where the plus and where the minus is in the cigarette lighter. This malfunction is treated by removing the burnt out element and installing a new one.

Replacing the cigarette lighter fuse

To carry out the procedure, you should have instructions for a specific car. Each machine has its own mounting block location and fuse assignment. You need to know where the plus and minus are.

On most cars, the box is located directly behind the front panel. However, on classics, fuse No. 6 is responsible for the operation of the cigarette lighter, and on some other models - the turn relay. Therefore, when making repairs, you should know which element we plan to change and where it is located. It is necessary to buy a fuse with the resistance recommended by the manufacturer.

Installing a second cigarette lighter

Many drivers lack an additional socket. There are several ways out of this situation. The simplest one is to install a special splitter that plugs into a standard connector. However, this can put a lot of stress on the circuit and cause the wires and fuse to blow. Therefore, some car owners install an additional car cigarette lighter.

The second method is more difficult, but more reliable. The procedure is carried out as follows.

We choose a suitable location for the additional device.
We are purchasing a new spare part. The black wire is the ground that we mount under the bolt on the body. Red is a plus, it goes to the battery, and yellow is responsible for the backlight of the device.
Cut a hole of suitable diameter.
We install a new spare part.
We connect all the wires, remembering where the plus and minus are in the cigarette lighter.
We remove debris and perform final assembly. Now the owner has two nests at his disposal.

In general, after a short lunch, in 30 minutes I removed the cigarette lighter through the wires.

In general, if anyone is interested, I’ll describe how I did it.

We will need: a splitter in the car - 1 piece, a thermal tube - 1 piece, a Phillips screwdriver, wire cutters, a lighter, double-sided tape, a button.

THE MAIN MAIN THING IS TO REMOVE THE CLAMP FROM THE BATTERY SO THAT THERE ARE NO TROUBLES! To begin with, I found on the Internet where the + and - are located on the cigarette lighter and power supply.

I ran the wire from the cigarette lighter behind the ashtray. Tobish remove the ashtray (4 bolts)

On my splitter the + was red and the minus was blue. On the cigarette lighter I specify that the red and white is a plus, the black is a minus, and the third wire is the cigarette lighter illumination.

The main problem with twisting (and not only in auto electrics) lies in the simplicity of execution. The essence of the connection is in the name and many rush into battle without familiarizing themselves with the hardware, as a result, a lot of “wrong” twists are made that fall apart, burn, etc. and so on. Hence the notoriety of this type of connection, flying like thunder from different points of the Internet. Pros: - minimum tools; — maintaining the integrity of the original conductors, only the insulation is damaged; — possibility of dismantling the connection. Cons: - small contact area or large connection dimensions; — low physical reliability of the connection. Taking into account all the pros and cons, I would recommend the correct twisting for low-current connections (all kinds of LED lights, DVRs, buttons, etc.). For power circuits such as headlights, PTF, etc. twisting is not the best option. In addition, in all cases, I strongly recommend that you carefully insulate the connection, and it is advisable to tape the connected wire to the main harness at some distance so that the connection does not experience physical stress (rag insulating tape is very suitable for this). How to make the correct twist? 1. We strip the original and connected wires by 1.5-2 cm. You can use a stationery knife for this. Be careful not to cut the veins or fingers. 2. We straighten the cores of both wires, forming something like a broom. 3. We insert the “broom” of the connected wire into the beginning of the “broom” of the main one so that the wires are mixed. If we connect to an existing wire, we also slightly straighten its wires and insert a new wire so that the wires are mixed. 4. Tightly twist the wires along the entire length with your hands. 5. We isolate, seal as necessary, and burnish.

I started doing it with a minus

Installing a second cigarette lighter

The second method is more difficult, but more reliable. The procedure is carried out as follows.

We choose a suitable location for the additional device.
We are purchasing a new spare part. The black wire is the ground that we mount under the bolt on the body. Red is a plus, it goes to the battery, and yellow is responsible for the backlight of the device.

Where is the plus and minus in the cigarette lighter?

Publication date: June 26, 2016. Category: Automotive equipment.

The first cigarette lighters were born back in 1920 and since then have become one of the most indispensable elements in a car. Over the years of the formation and development of mechanical engineering, the operating principle of this miniature structure has not changed, but its purpose has expanded significantly. Today, with the help of this device, car enthusiasts recharge phones, tablets and laptops, connect car pumps, vacuum cleaners, fans, compressors and much more. And of course, the cigarette lighter is simply indispensable for smokers, both for those who still smoke cigarettes and for fans of electronic cigars that charge via USB.

Unfortunately, despite the appearance of all kinds of tees for the cigarette lighter, there is only one central element, and it has a number of advantages and disadvantages that should be taken into account when using this useful device.

Advantages and disadvantages of car cigarette lighters

The most important advantage of a cigarette lighter is the ability to connect a huge number of electrical appliances to it, making life easier on the road. However, due to switching such large amounts of current, the design of this device is unreliable. In addition, we must not overlook the fact that every time we connect gadgets to the cigarette lighter, we create a mechanical load on its elements. Ideally, car manufacturers would consider increasing the strength by adding more presser feet. Then the plug would stay in the cigarette lighter more “confidently”.

Alas, so far most forks are equipped with only a spring-loaded contact and a pair of presser feet. During a trip and the natural vibration of the car, the contact between the socket and the plug is broken, as a result of which the cigarette lighter begins to spark, and sometimes even causes a short circuit and fire.

If this element fails, you can repair it yourself, the main thing is to maintain the polarity of the car's cigarette lighter.

Cigarette lighter circuit

If your car does not have a cigarette lighter or it is broken, then it is not necessary to contact a car mechanic. It is enough to understand how an electrical circuit works.

So, the plus in the cigarette lighter is the button itself. When you press it, the circuit closes and the coil begins to heat up. If we talk about where the minus is in the cigarette lighter, then there is nothing complicated here either - these are the side walls of the metal cylinder itself.

Knowing this parameter, you can easily install and repair a damaged cigarette lighter in a car. For this:

Unscrew the nut on the back of the device.
Disassemble the cigarette lighter.
Find the semiconductor wafer in its lower part and remove it if it caused the breakdown.
Cut off the protrusion on the device body.
Assemble the cigarette lighter.
Strip the wires for connecting the device (7 mm); you also need to crimp the terminals on them.
Remove the center console in your car and disconnect the lights.
Remove the block.
Connect the wires using special connecting clips. The first wire (white-brown) must be routed to the wire from the backlight. Connect the remaining two wires (yellow and black) to the cigarette lighter wires.
Pull the wires down and connect them to the cigarette lighter socket.
Reinstall the cigarette lighter.
Install the backlight.

In custody

As you can see, you can “reanimate” the cigarette lighter yourself. Plus and minus play a big role in this process, so it’s better to check everything several times before work. It is best to refer to the manufacturer's instructions and recommendations.

Pros or cons of multiple cigarette lighters

Inability to connect multiple devices to the cigarette lighter.

Hello everyone, a short review of a car cigarette lighter from China. Packed as standard

But when I opened it I was a little surprised, because I didn’t expect to see that it would be in a box and in a bag

Externally it looks something like this

I took the main dimensions from the website, and the backlight colors are also visible in the photo.

I took out my old cigarette lighter because it didn’t work (it didn’t lock when pressed)

Removed the light from the new cigarette lighter

After removing the old one, I discovered that they are powered by different contacts, the old one, apparently (albeit poorly) through a chip with contacts, and the new one through separate contacts

As a result, we had to power everything separately, but the old one came with one “minus”, and the new one needed two of them, and therefore the second “minus” was powered from the first

In total, the backlight works, the cigarette lighter is in the socket

Performs its function perfectly

But due to the fact that the main color of the lights in my car is green, I returned my old light back and put the socket from the new cigarette lighter in it (everything fit as it was)

The product was provided for writing a review by the store. The review was published in accordance with clause 18 of the Site Rules.

Don't burn out at work: how to connect several gadgets to the cigarette lighter?

In the summer, their owners usually only connect smartphone chargers and DVRs, which consume a nominal current, to the on-board network of their cars. But in the fall and winter, “pop warmer” capes, remote fan heaters, electric mugs, thermal glass scrapers and other car heating gadgets are plugged into cigarette lighters. All this junk, as a rule, is powered simultaneously through cigarette lighter splitters that have from two to five sockets, as a result of which many car owners encounter problems. And it would be okay if a contact came loose somewhere or a plug melted, but you can also burn your car... How can you not do this?

Who is guilty?

Physics and electrical engineering clearly state: in order to transmit large currents through detachable connections, the connectors must have a significant contact area, low self-resistance and be sufficiently tight. To understand the essence of the processes occurring in the car cigarette lighter socket and the corresponding plug of a 12-volt gadget, let’s disassemble the plug and take a look at its guts.

Let's figure out where the plus and minus are in the cigarette lighter: is it possible to mix it up?

If previously a car cigarette lighter (CA) was used only for its intended purpose, recently many devices have appeared that can be connected to the on-board network through it. The article discusses the car cigarette lighter: where are the plus and minus, advantages and disadvantages.

Advantages and disadvantages of car cigarette lighters

Once a cigarette lighter appears in a car, it remains an integral part of the equipment.

With the development of technology, many devices have appeared that require sufficient power from the vehicle’s on-board network. AP began to be used as a car socket. The operating principle of the device has not changed over the years. But various tees and adapters appeared that expanded the possibilities of using AP (the author of the video is Do It Yourself).

The main advantage of a car cigarette lighter is the ability to connect a large number of different electrical appliances that may be needed on a long trip or will increase the comfort of the trip.

Since large amounts of current pass through the AP, its design is unreliable. In addition, the device constantly experiences additional mechanical stress due to the constant connection of various devices. During the trip, due to vibration, the contact between the AP and the socket is broken. As a result, sparks may appear, which may even cause a short circuit.

Electrical circuit of the device

To successfully repair an AP, you must have at least basic knowledge of electrical engineering and know how the electrical circuit of the device works: where is the plus and where is the minus.

You can use a multimeter to find plus and minus.

Photo gallery “Cigarette lighter and its circuits”

In a car cigarette lighter, the plus is a handle-button that the user presses. When you press the button, the electrical circuit closes and the coil begins to heat up. The downside is the sides of the metal casing of the AP.

Knowing the polarity of the device, it will not be difficult to repair the car cigarette lighter.

To do this you need to do the following:

Unscrew the nut on the back side of the AP.
Next, we disassemble the device.
At the bottom of the device is a semiconductor wafer. This may be the cause of the malfunction. In this case, it must be removed.
On the body you need to cut off the protrusion using a file.
Now the device needs to be assembled.
Next, you should strip the wires not 7 mm in order to then connect them. In addition, you need to press the terminals on them.
In the cabin, it is necessary to dismantle the center console and turn off the backlight.
We take out the block and connect the wires using special clips. We connect the white-brown wire to the wire from the backlight. All that remains is to connect the yellow and black wires to the AP wires.
Then the wires are laid down and connected to the plug from the car cigarette lighter.
Next, the cigarette lighter is returned to its place, and the backlight is connected.

Useful for car enthusiasts - everything about cars

Needless to say, how necessary a cigarette lighter is in a car - and this basically has nothing to do with smoking. The thing is that the cigarette lighter socket serves as a power source for many electrical appliances when it is not possible to connect them to the main outlet.

What devices can be connected via the cigarette lighter:

charger for mobile phone and tablet,
DVR,
navigator,
radar detector,
vacuum cleaner,
car refrigerator,
heated seats,
perhaps a walkie-talkie,
on old VAZs - car radio, etc.

The convenience of a cigarette lighter is undeniable, but there is also a drawback: you need to constantly keep under control the total power of all devices connected to the device - it should not be more than 120 watts, the current should not exceed 10 amperes.

The more intense the current, the more reliable the cigarette lighter contacts, which become loose from shaking and jolts while traveling, should be. As a result, a short circuit and fire occurs in the car. Various adapters and splitters, which allow you to connect several electrical appliances to the cigarette lighter at once, do not add reliability to the device, and thus significantly increase the load on it.

How to connect the cigarette lighter: sequence of work

The process of connecting the cigarette lighter begins with preparing the necessary tools: a file or needle file, soldering iron, screwdriver and pliers.

To begin, remove the cigarette lighter and disassemble it;
Remove the semiconductor wafer from it, it often interferes with the normal operation of the device;
Use a file to file off the protrusion on the cigarette lighter body;
Assemble the cigarette lighter;
First you need to strip the wires with which it is connected and crimp the terminals onto them. Do not reverse the polarity of the connection!
Remove the center console; Sometimes it may additionally be necessary to dismantle the lever casing and armrest in order to unscrew the screws;
Remove the backlight wires, and then the entire unit;
Now connect the wires, securing them with connecting clips. The wires are connected according to the following scheme: the brown wire is connected to the backlight wire, the black and yellow wires are connected to the cigarette lighter wiring. Remember to isolate each connection;
Pull the wires down to connect to the cigarette lighter socket;
Place the cigarette lighter in its seat in reverse order. First push through the ring, then the glass itself. If necessary, adjust the diameter of the ring to the diameter of the hole using a needle file;
Replace the backlight.

Design and principle of operation

The car cigarette lighter has a simple design and is a small metal cartridge with a plastic handle and button. A nichrome spiral is installed under the body, which is heated by electric current.

There is a special socket on the instrument panel or in another part of the car. If you insert the cigarette lighter into it and press the handle, it will be connected to the on-board network.

The positive contact mates with the central terminal of the socket and the spiral of the device. The negative interacts with the socket base and the plug clamping mechanism. When using the cigarette lighter, current is supplied through the nichrome element, which contributes to its heating.

After reaching the maximum temperature indicators, the thermal relay is activated, and the cigarette lighter is disconnected from the on-board power supply.

To protect the connector from blowing, manufacturers install a 10 A fuse. It is located in the fuse block and is indicated by the “cigar” marking or a cigarette icon.

Since its appearance in the first half of the 20th century. The internal structure of the cigarette lighter has remained virtually unchanged.

The key advantage of the device is the ability to power a variety of electrical appliances, which make long driving comfortable and safe.

However, due to the consumption of a large amount of energy, the structure may fail. In addition, there are other disadvantages of such an accessory. When gadgets are frequently connected, the internal elements of the device are subject to a large mechanical load, which contributes to their wear.

Most fork models have only spring elements and a few pressure forks. Therefore, when driving over rough terrain, natural vibrations are created that disrupt contact and lead to sparks in the cigarette lighter. This phenomenon can cause a short circuit and even lead to a fire.

Correct connection of the cigarette lighter

You can repair a car device, dismantle it or install it yourself. To replace the cigarette lighter you will need the following list of tools:

Phillips/minus screwdriver;
blowtorch with solder;
connecting terminals for plus and minus.

Repair is carried out as follows.

We dismantle the car cigarette lighter. It is removed differently in each car. Sometimes you just need to pry the cartridge, and sometimes you have to remove the lining of the central tunnel.
We disassemble the car cigarette lighter. We find the semiconductor wafer at the bottom. This is what often causes breakdowns. Let's delete it.
We cut off the protrusion on the outer casing.
We assemble the cigarette lighter in the reverse order of disassembly.
We strip the connection wires at least 5 mm.
