IDC receptacles use cold-welded wires and can hold from six to 64 wires. They are used in telecommunications and networking and allow for easy cable replacement and wiring configuration changes. The receptacle head contains blades that cut through wire insulation and make a gas-tight connection. IDC sockets are commonly used in the telecommunications and networking industries and have indicators to show where the first wire should go.
Insulation Displacement Connector (IDC) receptacles are receptacles that use cold-welded wires placed in the receptacle head. The number of wires that can be inserted into an IDC receptacle ranges from six to 64, and there is always an indicator on the head of the receptacle to show where the first wire should go. IDC sockets are used in telecommunications and networking and allow operators to replace cables and change wiring configurations with relative ease. This was initially made for single cables but evolved into plugging multiple cables into the head of the receptacle.
When an IDC receptacle locks onto a set of wires, it cold solders them to the head of the receptacle, meaning it makes a tight connection like with solder, but without the heat. Cold welding is done using vacuum pressure and the connection between the socket and the wires is gas tight. The head contains small blades that cut through the plastic insulation of the wire and allow for interfacing with the internal wire. This allows the outlet block to use power from the wires into any device that has a connection.
The amount of wires and the spacing between the wires differ for each IDC socket. The common range of cables is from six to 64, with the broader end of the spectrum used on network cables. Using these socket blocks, users can make their own ribbon cables, but a manufacturer often bundles the wires together. IDC sockets are meant to be single use but, if users are able to carefully pull out the cables without damaging them, the socket can be used more than once.
IDC sockets are most commonly used in the telecommunications and networking industries. Home use is exclusive to phone jack connections, where small IDC heads are used. The classic picture of a large server with hundreds of colored wires plugged into different sockets and jacks is how IDC sockets are typically used. This allows network and telecom operators to inject a large number of cables saving space and making the area look neater than if all cables were connected individually.
All IDC sockets have some sort of indicator to show where the first wire should go. With some, a red wire is used as the first wire but because many connections use several red wires this designation is less common. Most commonly, there is a raised V or triangle to show where the first wire should go. By ignoring this position, the IDC socket will not work properly.
