Abstract
The invention is a plastic connector assembly characterized by a metal washer 10b, located between a wave washer 30 and the shoulder 21 of the connector housing 20. The metal washer 10 is further characterized by at least one projection 11 or 12 thereon which prevents relative motion between the metal washer 10b and the housing shoulder 21. This reduces the wear on the shoulder of the housing. Similarly to reduce wear on the shoulder in the coupling ring a second metal washer 10a may be placed on the other side of the wave washer 30 to accomplish the same purpose.
Claims5
In combination with an electrical connector of the type having:
- a cylindrical housing comprised of plastic and having a central axis, a forward portion, a central portion, a rear portion, an annular groove in said central portion, and an annular shoulder spaced forwardly of said groove;
- a plurality of electrical contacts mounted in said housing, each of said contacts having a forwardly facing mating portion;
- a coupling ring telescoped over a portion of said housing, said coupling ring having a rear portion and a forward portion adapted to connect to a similar housing having contacts that are adapted to mate with said contacts in said housing, the rear portion of said coupling ring having an inwardly extending annular flange that includes a forward face and a rear face;
- and means for rotatably mounting said coupling ring to said housing between the groove and the shoulder of said housing, the improvement wherein said mounting means comprises;
- a snap ring located in the groove in said housing, one side of said snap ring abutting the rear face of said coupling ring flange;
- a wave washer located between the forward face of said coupling ring flange and the shoulder of said housing;
- a metal washer positioned against the rear face of said housing shoulder;
- and
- means for preventing relative movement between the metal washer and the shoulder of the plastic housing, said means including at least one axial projection on said metal washer extending towards the rear face of said housing shoulder to fixedly position the washer against the rear face.
