TE Connectivity – Receptacles and housings combine low insertion force with high retention strength


TE Connectivity (TE) produces a wide range of Positive Lock receptacles and housings which provide a superior choice in terms of performance, ease of use and cost competitiveness.

There are three series of terminals in the TE Positive Lock portfolio. Receptacles in the Mark I family feature a lower insertion force than any other receptacles in their class. To reduce the risk of unwanted back-out, the receptacles’ termination is completed with a mechanical snap that the assembler can both hear and feel. Mark I receptacles provide a reliable, easy to use solution for high-current applications.

Combining low insertion force with high retention strength, the Mark II family provides a cost-effective, reliable means to terminate electrical circuits.

Recently introduced models in the Mark II family meet the requirements of high-temperature applications. The High Temperature 250 series features nickel-plated, high-strength, low-alloy steel terminals rated for operation at up to 250°C, and a new liquid-crystal polymer housing rated for up to 240°C. Both straight and flag configurations are available.

The Mark III family of Positive Lock receptacles enhance both insertion force and contact retention strength to facilitate assembly operations. The Mark III receptacle’s detent lever, similar to that of the Mark II product, has a cut-out in the back transition area of the terminal.
