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 ...
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 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.
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 ]
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 ...
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.
Central metal-tipped insulated spike contacted cable core; smaller spikes contacted cable shield. Note black mark on cable sheath indicating suitable location for transceiver A vampire tap (also called a piercing tap ) is a device for physically connecting a station , typically a computer, to a network that used 10BASE5 cabling.
The punch-down blocks on patch-panel and wall-port jacks are designed for use with solid core cable. These work via the insulation-displacement method, whereby the device pierces the sides of the insulation and "bites" into the copper conductor to form a connection. Punchdown blocks are used as patch panels or as break-out boxes, for twisted ...
