An insulation-displacement contact (IDC), also known as insulation-piercing contact (IPC), is an electrical connector designed to be connected to the conductor(s) of an insulated cable by a connection process which forces a selectively sharpened blade or blades through the insulation, bypassing the need to strip the conductors of insulation ...
The connectors are manufactured in many capacities, including 14-, 24-, 36-, 50-, 64-, and 100-pin varieties. They may be mounted on boards, panels, or may terminate cables. Wires are attached by means of solder, crimping or insulation displacement. Female connectors have bail locks for a sturdy connection to the male connector. Screws may also ...
A punch down tool, punchdown tool, IDC tool, or a Krone tool (named after the Krone LSA-PLUS connector), is a small hand tool used by telecommunication and network technicians. It is used for inserting wire into insulation-displacement connectors on punch down blocks, patch panels, keystone modules, and surface mount boxes (also known as ...
Since stripping insulation from wires is time-consuming, many connectors intended for rapid assembly use insulation-displacement connectors which cut the insulation as the wire is inserted. [1] These generally take the form of a fork-shaped opening in the terminal, into which the insulated wire is pressed, which cut through the insulation to ...
The part numbers used for the female contact pins depends on the detailed design, the surface coating (for example tinned or gold plated) and the form of supply. Example part numbers are any of TE Connectivity / AMP 170204-* (loose pieces) or 170262-* (pieces supplied in strips), where * is 1 or 2 or 4.
Krone LSA-PLUS (or simply krone) is an insulation-displacement connector for telecommunications. It is a proprietary European alternative to 110 block . The Krone LSA-PLUS system is not limited to telecommunications, as it is also popular in broadcast systems, where audio interconnections and their associated control systems often use krone wiring.
Connectors on this cable would be designated: 1A1W35P1; 1A1W35P2; ASME Y14.44-2008 continues the convention of Plug P and Jack J when assigning references for electrical connectors in assemblies where a J (or jack) is the more fixed and P (or plug) is the less fixed of a connector pair, without regard to the gender of the connector contacts.
The terminals on the back part were originally large screw terminals, later replaced in all BT NTE5 sockets by insulation-displacement connectors (IDCs). As BT no longer has a monopoly of internal wiring, they make a substantial charge if a fault reported to them is found to be in the customer's internal/domestic wiring.
