Abstract

This invention relates to a receptacle for connecting a terminated coaxial cable to circuits on a printed circuit board. More particularly, the receptacle consists of a stamped and formed shell member which contains a stamped and formed center contact and which also terminates the ground circuit to the board. The center conductor contact is embedded within a dielectric housing electrically isolating it from the shell member. Both the shell member and center contact contain formed biasing means to frictionally retain the coaxial cable.

Claims

1. A receptacle for mounting on a printed circuit board to removably receive a coaxial cable of the type having a center conductor, a terminated braided shield and a dielectric inbetween, which comprises:

a. an electrically conductive, coaxial cable receiving shell member having a floor from which a pair of legs depend, said legs being adapted to be inserted into openings in a printed circuit board, said floor further having an opening positioned between the legs, said shell member further having a front section defined by said floor and a pair of sidewalls with the top of each sidewall being bent inwardly and downwardly to provide spring members which biasingly engages the terminated braided shield portion of the coaxial cable which may be inserted therein, and a rear section;

b. a dielectric housing positioned in the rear section of the shell member, said housing having a depending rail extending along either side of the base thereof, said rails adapted to be positioned in the opening of the floor of the shell member; and

c. a contact positioned in the dielectric housing and having a rectangular portion adapted to removably receive an end of the center conductor of the coaxial cable and further having a leg depending downwardly from one end of the dielectric housing and through the opening in the floor of the shell member for insertion into a printed circuit board.

2. A receptacle for mounting on a printed circuit board to removably receive a coaxial cable of the type having a center conductor, a terminated braided shield and a dielectric inbetween, which comprises:

a. a stamped and formed elongated shell member into which the coaxial cable may be inserted, said member having a floor and a pair of legs depending therefrom and adapted to be inserted into openings in a printed circuit board, an opening in the floor between the legs, a front section defined by a pair of sidewalls with the top portion of each sidewall bent inwardly and downwardly to provide inverted triangular-shaped spring members which biasingly engages the terminated braided shield portion of the coaxial cable which may be inserted therein, and a rear section defined by a pair of sidewalls and an upright rear panel wall with the top portion of each sidewall bent laterally inwardly to enclose the rear section;

b. a dielectric housing made from insulating material and having a passageway, a vertical groove extending downwardly from one end of the passageway, and along each longitudinal side of the base a depending rail, said housing positioned in the rear section of the sheLl member with the rails positioned in the floor opening; and

c. a stamped and formed center contact having a rectangular portion in which one side thereof is arched inwardly to provide a spring member and further having a leg, said retangular portion positioned in the passageway in the dielectric housing with the leg depending downwardly along the vertical groove and passing through the floor opening in the shell member, said leg adapted to be inserted in a printed circuit board, said rectangular portion adapted to removably receive an end of the center conductor of the coaxial cable with the spring member frictionally retaining such therein, said leg connecting the circuit on the printed circuit board with an inserted center conductor.
