CONTACT MATERIAL VARILOK CRIMP-AND-INSERT CONTACTS

The primary contact material used is phosphor bronze. Theelectrical conductivity of copper alloys are extremely good. Within the Varicon concept, the contacts must also perform as springs and these alloys offer the elastic properties and the endurance required by today’s rugged applications. The crimp-termination, insertable / removable Varilok contactoffers a solderless connection between wire and contact as well as strain relief for the wire. This contact snaps into the insulator quickly and easily. With our simple tool it can beremoved without difficulty, yet it locks securely into place andcannot twist or bend out of alignment. Varilok contacts also are available with wire-wrappable, solderand taper-tab tail configurations. Available loose for smallscale production and replacement purposes, the Varilok contact is also supplied on reels for use with fast, economi- cal automatic crimping machines reducing man-hour requirements and production costs in medium and large- scale production runs. Because the contact can be crimped to the wire and installed into the insulator at any point during the manufacturing operation, it offers the user convenience and flexibility. Reels contain 1800 standard contacts or 3000 miniature contacts.

CONTACT PLATING

A nickel underplate of 50 to 100 microinches, followed by a minimum of 10 microinches of gold plate is AVX’s standard contact plating. The gold plate prevents the formation of insulating oxide films while the nickel plate provides a hard backing. It, in turn, reduces wear on the gold and prevents diffusion between the gold and base metal. Other plating thicknesses, such as those required by military specifica- tions, can be supplied on request.
