IDC is a method of riveting insulated or unpeeled conductors to connectors. This method is equally applicable to non-insulated wires. This technology is of great value to many different types of connectors. So I will introduce you to the IDC connector.

Definition of IDC connector
The IDC is an insulation-displacement contact (IDC), also known as insulation-piercing contact (IPC), is an electrical connector designed to be connected to the conductor of an insulated cable by a connection process which forces a selective sharpened blade or blades through The insulation, bypassing the need to strip the conductors of insulation before connecting. When properly made, the connector blade cold-welds to the conductor, making a theoretically reliable gas-tight connection.
IDC connector application
l Ribbon cable
Ribbon cable is designed to be used with multi-contact IDC connectors in such a way that many IDC connections can be at at, saving time in applications where many connections are needed. These connectors are not designed to be reusable, but can often be Re-used if care is taken when removing the cable.
Pin 1 is typically indicated on the body of the connector by a red or raised "V" mark. The corresponding wire in a ribbon cable is usually indicated by red coloration, a raised molded ridge, or markings printed onto the cable insulation. Connector pin 2 is opposite pin 1, pin 3 is next to pin 1 along the length of the connector, and so on. On the cable, the wire connected to pin 2 is next to the wire connected to pin 1 (the red coded wire ), and so on.
l Telephone and network plugs
In some types of telephone and network plug, including the BS 6312 and the registered jack (RJ) family, generally separate wires in a sheath are used. In these applications, the outer sheath is stripped then the wires are inserted into the connector and a The special termination tool is used to force the conductors into the contacts. Traditionally the connectors have been used with flat cable which makes it easy to ensure the right conductors go into the right slots. Of the conductors by hand before inserting them into the connector.
l Punch-down blocks
Punch-down blocks are intended to connect individual conductors punched down into each position in the block with a special punch-down tool. Punch-down terminations are also generally seen in telephone and network connectors, in patch panels and distribution frames, and in telephone Equipment such as PBXs.
IDC connector placement
l aims
The wire terminal is flush with the outer edge of the connector;
The cover of the connector is fully pressed into the connector;
After the cover is pressed, the lock is fully engaged and locked;
The wire is folded back, and if possible, the radius of the fold should be twice the thickness of the wire;
l Precautions
The size of the cut end of the wire is flush or the size of the outer edge of the connector is less than or equal to the thickness of the wire, and does not affect the minimum electrical characteristics of the wire;
The impression of the fixture does not damage the insulation of the wire or connector surface;
The wire radius is folded back. If possible, the wire is flush with the connector and does not affect the installation of the connector;
l Possible situations and effects
The lock is not fully engaged and locked after the cover is pressed down
Any damage to the latch or reverse buckle after pressing down;
All core wires of the wire do not fully enter the IDC contact area;
Wire foldback, affecting the mechanical fit of the connector
The wire extension of the edge of the connector exceeds the thickness of one wire；
The application community of the IDC connector can be said to be not too small, you may also find it in the things you use, as long as you want to find it.
