Dismountable 4-pin 3.5mm audio plugs for headphone repair

51570

In this article we will look at what types of plugs there are.

, what is pinout (mini jack and not only), and what types exist.
We will also consider repairing the headphone plug and soldering a 3.5 mm mini jack. All this is not at all difficult, the main thing is to know just a couple of nuances. ⭐ Best wired headphones (2022):

Pinout of the wire of the 3.5 connector (Jack) with and without a microphone.

Nowadays, the pinout of headphone wires with a microphone shown in the first picture below is generally used everywhere, but there is also another one, which is mainly used on old phones and in phones from some manufacturers. They differ in that the microphone and ground contacts are swapped.

If you have resoldered the headphone plug and you have a quiet sound in the headphones, and when you press the headphone call button the volume in the headphones increases, then you should resolder the ground and microphone wires (swap them).

Cable cutting.

You can prepare a cable in different ways, but the least traumatic method for conductors is to remove the insulation using a soldering iron.

Holding the soldering iron with one hand, rotate the shielded wire around its axis with the other hand, while pressing the insulation against the sharp edge of the soldering iron tip. https://oldoctober.com/

If after this you cannot remove the insulation by hand, you can use side cutters.

It should look something like this.

We also remove insulation from individual wires in the same way.

Now you can give the cable a look suitable for tinning.

What to do if your headphones don't work. DIY headphone repair.

We will need a knife, a soldering iron, solder, rosin, cut off 5-10 cm of wire from the plug, remove all the insulation from the plug, just in case, remember the sequence of wires by color (sometimes they are different). Strip the wires and solder them to the 3.5 mm jack. I advise you to fill the soldering area with hot glue (hot glue) and compress it with heat shrink, so the connection will last much longer. The wires will not solder well, but I advise you to warm them up longer, and you will succeed. Also see USB cable pinout.

Four-wire plug

There are two different options here.

1. Ordinary headphones without a microphone and control buttons. 4 wires are connected to the plug: a minus from each copper-colored speaker and a plus (blue with red or green with red). For convenience, the negatives are twisted into one bundle and the result is three wires that need to be soldered to their specific places.
2. Headset with microphone. Here the plug has 4 types of contacts: one from each speaker, one for the microphone, and there is room left for soldering a common wire or ground. Schematically, such soldering looks like this:

Applications [ edit | edit code ]

Analog audio [edit | edit code ]

3/180° and 5/180° connectors were initially standardized and widely used in Germany, Czechoslovakia and, later, in the USSR and CMEA countries for connecting analog audio equipment, such as a stereo tape recorder with a stereo amplifier or preamplifier. Four contacts were used for the signal and a fifth for the common wire. The patch cords had a connector at each end, and the contacts were connected one-to-one: contact 1 with contact 1, 2 with contact 2, etc. The contacts on the plugs are numbered (from right to left, looking from the outside of the connector, contacts up ): 1-4-2-5-3. The holes in the sockets are also numbered 1-4-2-5-3, but from left to right (looking at the holes). This numbering is used because the base was a three-pin connector with a natural numbering of 1-2-3, and then pins 4 and 5 were added to it. Since a three-pin plug can be inserted into a five-pin socket, the numbers of the connecting pins are the same.

A four-channel wire wired in this way is sometimes simply called a DIN cord.

DIN wire
or
DIN cable
. For mono connections, 3/180° plugs are sufficient. When a mono plug is inserted into a stereo jack, it connects to the left channel, which is why some stereo equipment had mono/stereo switches. Such an interface was rare in the US market and gradually disappeared from new equipment, both in Germany and around the world, giving way to RCA (tulip) connectors. DIN connectors are still used in Naim Audio devices [6].

Other uses[edit | edit code ]

5/180° connectors were often used for:

• SYNC interface for electronic musical instruments;
• interface M >[7][8] );
• connecting two controllers of radio-controlled models for training purposes.

The DIN connector has seen other applications in its time besides audio. The TurboGrafx-16 game console used a 5-pin DIN connector for video and audio output. The Atari XEGS, along with the Commodore C64 and BK, used a DIN connector to connect to the power supply. Also, early C64s that only supported composite video output used a 5-pin DIN for video and audio, but newer C64s that supported chrominance/luminance output used an 8-pin DIN to carry additional signals. The Neo Geo and Neo Geo CD used an 8-pin DIN for composite video, RGB video, and mono audio outputs, as well as +5 V to power the RF modulator [9]. Dragon 32 computers used 4 5-pin DIN connectors for joysticks, tape recorder and monitor output. The TRS-80 Model I used three identical 5-pin DIN connectors for the power supply, video output and tape recorder, which made it easier to destroy the device if connected incorrectly. Much the same thing was observed in Soviet BC computers, which used four 5-pin DIN connectors for tape recorder, black and white video, RGB color video and power supply.

Soviet ONTs-VG connectors [edit | edit code ]

In the Soviet Union, 3- and 5-pin DIN connectors, called ONTs-VG, were used everywhere. The 5-pin connector was also called SSh-5, SG-5 (Ш - plug, G - socket), and the three-pin connector - SSh-3, SG-3. Initially, this was factory audio equipment, but then radio amateurs and cooperatives fell in love with this method of connecting equipment, and began installing such connectors in almost any device that dealt with low-frequency signals. It is impossible to talk about standard wiring of such connectors. While 3- and 5-pin connectors could be easily purchased, the situation with the rest was difficult. 4-pin connectors were not seen anywhere, neither on the equipment nor for sale. Six- and 7-pin connectors were difficult to obtain, and 8-pin connectors were very exotic.

As an example, we can mention the Soviet color TV “Raduga-315” with a 51 cm diagonal kinescope. It used a standard DIN-6 connector to connect a video signal source (for example, a VCR). Due to the fact that the signal playback mode on the TV was turned on with a separate button, a cable with an accessible SSH-5 connector was used to connect the VCR to the TV, the outer terminals of which 1 and 3 were simply bitten off with wire cutters, which ensured mechanical compatibility with the socket on the TV.

Since there were many non-standard ways to use connectors, only the standard ones are mentioned in the table.

Other examples of headset jack wiring

Here, without looking or checking, you can solder two gold wires together

It's just that each channel has its own wire for ground. From an audiophile point of view, this option is more correct than one ground wire and contributes to a wider stereo base.

In general, it turns out that the whole problem of repairing the headset connector comes down to determining where the ground is that needs to be twisted to get 4 wires.

I repeat once again - the earth is always yellow. Also, mixtures of yellow with other colors are usually also earth.
