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 ...
It is named because the solid copper wires are "punched down" into short open-ended slots which are a type of insulation-displacement connector. These slots, usually cut crosswise (not lengthwise) across an insulating plastic bar, contain two sharp metal blades which cut through the wire's insulation as it is punched down. These blades hold the ...
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.
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 vampire tap usually had an integrated AUI (Attachment Unit Interface) in the form of a DA-15 connector, from which a short multicore cable connected to the network card in the station (host computer). Vampire taps allowed new connections to be made on a given physical cable while the cable was in use.
Internally, the contacts in the plugs have sharp prongs that, when crimped, displace the wire insulation and connect with the conductors inside—a mechanism known as insulation displacement. Cables have either solid or stranded (tinsel wire) conductors, and a given plug is designed for only one type. The sharp prongs are different in the ...
BIX connectors also have a pair-splitter to facilitate fast arranging of wires on the punch-down block. There are many types of BIX connectors, the most popular kinds being the 1A and the 1A4. 1A: Distribution connector, 5-pair markings [1] 1A4: Distribution connector, 4-pair markings [1] 2A: Bridging connector, 12 2-pair clips [1]
