Insulation-displacement connector

The insulation displacement terminals is a joining technology in electrical engineering for multi-pole insulated copper wire cable.

In communications, the wires of a cable insulation are together with a special tool, the punch down tool or application tool called, individually pressed into a so-called cutting clamp. In this case, the excess wire end through the tool and cut by the sharp contacts in the metal cutting clamp the insulation of the wire is cut and manufactured a gas-tight electrical connection. This connection technique works without soldering, screws and stripping, so it is also called soldering, screws or no stripping technique, short LSA Technology, respectively. LSA technique is less suitable or unsuitable for stranded cable.

In communications, the LSA technique is used since the early 1970s at the main distribution of switching centers, since the early 1980s in the line technology and distribution boards.

Today, this is also a common way to, for example, in a computer network to connect network sockets. The principle is similar to crimping an RJ45 connector.

In the area of ​​internal wiring of electronic devices or assemblies connectors are often used, which are also connected by cutting clips with the cable. In this case, the expression IDC or the abbreviation IDC ( Insulation - displacement connector for ) is more usual. In this case, a matching flat ribbon cable is inserted into a slot of the connector. Then the slot is compressed with a special press or pliers, if necessary also with a vice, which can be contacted at once with insulation all conductors. In contrast to the above mentioned technique, the LSA cable is cut off automatically, so that also the middle of the cable connector can be attached.

The application with connectors according to DIN 41651 in the form of the data cable from the built in PC hard drives is known ( with ATA/ATAPI- or SCSI technology ) or floppy drives. But many other connectors, such as D- Sub or Centronics connectors are available with insulation displacement technology.
