Cable idc socket strip

Because of the way the connector attaches to the cable, this means in a two-row header, pins in one row have odd numbers and pins in the other row have even numbers. The most common jumper spacing is 2. If pin headers are optional, the PTH variant is often chosen for ease of manual assembly. Headers are often sold as long strips typically 40 or 50 pins for the dual row versions which can easily be broken off to the right number of pins. A notch key in the guide box normally prevents placing the connector polarised by a "bump" on one side the wrong way around. Board-in, or transition connectors allow an inexpensive way of permanently connecting a ribbon cable to a PCB, the cable is terminated to the connector, which is soldered, or pushed by press fit into the PCB.

The corresponding wire in a ribbon cable is usually indicated by red coloration, a raised molded ridge, or markings printed onto the cable insulation. Ribbon cable[ edit ] Ribbon cable is designed to be used with multi-contact IDC connectors in such a way that many IDC connections can be made at once, saving time in applications where many connections are needed. Traditionally these connectors have been used with flat cable which makes it easy to ensure the right conductors go into the right slots. Connectors are categorized by pin spacing in mm pitch , number of pins, and number of rows. Telephone and network plugs[ edit ] In some types of telephone and network plug, including the BS and the registered jack RJ family, generally separate wires in a sheath are used. History[ edit ] Modern IDC technology developed after and was influenced by research on wire-wrap and crimp connector technology originally pioneered by Western Electric , Bell Telephone Labs , and others. In these applications, the outer sheath is stripped then the wires are inserted into the connector and a special termination tool is used to force the conductors into the contacts.

Punch-down blocks[ edit ] Punch-down blocks are intended to connect individual conductors punched down into each position in the block with a special punch-down tool.

These connectors are not designed to be reusable, but can often be re-used if care is taken when removing the cable.
