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 ...
Punch-down blocks are a very quick and easy way to connect wiring, as there is no stripping of insulation and no screws to loosen and tighten. Punch-down blocks are often used as patch panels , or as breakout boxes for PBX or other similar multi-line telephone systems with 50- pin RJ21 ( Amphenol ) connectors. [ 2 ]
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 ...
A 110 punch block. A 110 block is a type of punch-down block used to terminate runs of on-premises wiring in a structured cabling system. The designation 110 is also used to describe a type of insulation displacement contact (IDC) connector used to terminate twisted pair cables, [1] which uses a punch-down tool similar to the type used for the older 66 block.
A split-50 M-type 66 block with bridging clips attached. A 66 block is a type of punch-down block used to connect sets of wires in a telephone system. They have been manufactured in four common configurations, A, B, E and M. [a] A and B styles have the clip rows on 0.25" centers while E and M have the clip rows on 0.20" centers.
The cables are typically made with copper wires measured at 22 or 24 American Wire Gauge (AWG) (0.644 or 0.511 mm²), [5] with the colored insulation typically made from an insulator such as polyethylene or FEP and the total package covered in a polyethylene jacket.
Some keystones use a pass-through type connector, where there is a jack on both the front face and the rear side. Others only have a jack on the front and employ a different mechanism for hard-wiring signal cables to the rear, such as a mini 110 block , an insulation-displacement connector , or a crimp or solder connection.
The connector provides power to the keyboard on the outer two contacts and receives data signals on the inner pair. The cable between the computer and the keyboard is a coiled cord with an appearance very similar to a telephone handset cable. [11] The connector on the Amiga 1000 uses crossover wiring, similar to a telephone handset.
