Abstract

A connector system is configured for macro motion. Two mating terminals are configured so that during macro motion cycles, the resistance between two terminals does not substantially increase. One terminal can have multiple, somewhat spherical-shaped mating surfaces while a mating surface on the other terminal can be flat. The mating terminals can be configured to provide desirable resistance performance after more than 5000 cycles of macro motion.

First claim

We claim:

1 . A connector system, comprising:
a first connector; a second connector configured to mate with the first connector, wherein one of the first and second connector includes a first housing with a projection and the other of the first and second connector includes a second housing with a receptacle configured to receive the projection; a first terminal supported by the first housing; and a second terminal supported by the second housing and configured to matingly engage with the first terminal, wherein one of first and second terminal includes two fingers configured deflect upon engagement with the first terminal and the other of the first and second terminal including at least one contact to engage the two fingers, the two fingers providing two points of contact, wherein the first and second terminal are configured to provide a low electrical resistance increase for at least 5000 macro motion cycles.

2 . The connector system of claim 1 , wherein the at least one contact includes an undercoat material and a plating formed by a noble metal.

3 . The connector system of claim 2 , wherein one of the two fingers and the at least one contact includes a lubricant configured to be chemically stable at a temperature of 90 C. during the macro motion cycles.

4 . The connector system of claim 3 , wherein the terminals are configured to withstand 10,000 macro motion cycles.

5 . The connector system of claim 4 , wherein the macro motion cycle includes a translation of at least 0.25 mm.

6 . The connector system of claim 5 , wherein each of the fingers exert less than 100 grams of normal force.

7 . The connector system of claim 6 , wherein the contact includes two sides and each of the two fingers engage a different one of the two sides.
