Abstract

In a connector having a first and a second contact, the second contact has a portion covered with an insulating member. The insulating member causes contact timings of the first and the second contacts relative to a counterpart connector to be staggered from each other. The first and the second contacts are held by a housing which is attachable and detachable relative to the counterpart connector. It is preferable that the first and the second contacts have chamfered portions, respectively, and that one of the chamfered portions is covered with the foregoing insulating member.

Claims

1. A connector comprising:

first and second elongated spaced parallel contacts formed by conducting material strips of equal length, each of said strips having a tip end with a chamfered portion, said tip ends being angularly directed away from each other to form a flared entrance for receiving a counterpart connector having mating contacts which meet with said parallel strips,

a molded plastic housing having an open space for receiving said counterpart connector with said first and second strips extending along opposite side walls of said open space,

said strips being integrally molded into said plastic housing with surfaces of said counterpart connectors in said space, said integrally molded housing being free of internal cavities adjacent said strips, and

insulating means at said tip end of one of said strips for preventing an immediate contact with a corresponding one of said mating contact, whereby said strips and mating contacts make connections at staggered time intervals, said insulating means forming a substantially smooth mechanical transition to said surface of said one of said strips whereby the mating contact on said counterpart connector slides into and out of said connection substantially without any discontinuity of said sliding motion, thereby preventing contact bounce and wear.

2. The connector of claim 1 wherein the angular tip of end said one strip is buried in said plastic during molding thereby forming said insulating means and making said smooth transitions to said surface of said one strip.

3. The connector of claim 1 wherein said insulating means is an insulating coating applied to said angular tip end of said one strip.

4. The connector of claim 3 wherein said insulating coating is applied to said tip end prior to said one strip being molded into said housing.

5. A connector as claimed in claim 1, wherein said insulating member is made of resin.

6. A connector as claimed in claim 5, wherein said resin covers the portion of said one of said first and said second contacts through molding.

7. A connector as claimed in claim 5, wherein said resin covers the portion of said one of said first and said second contacts through coating.
