Abstract

An electrical device is provided with a receptacle for receiving a radio. A lever carrying one or more contacts is pivotally positioned on one wall of the receptacle so that when the radio is inserted in the receptacle, the lever is pivoted and its contacts brought into engagement with contacts on the radio.

Claims

1. An improved device for providing electrical connections between an electrical device having a generally rectangular receptacle and between a radio having a generally rectangular shape for fitting into said receptacle, said device comprising:

a. at least one wall forming one side of a receptacle, said wall having an inner surface and an outer surface;

b. said inner and outer surfaces extending from a front edge of said wall in a selected direction toward the rear of said wall;

c. a keying projection positioned on said inner surface, said keying projection having a stop surface located at a selected point on said inner surface between said front edge and said rear, and extending from said stop surface toward said rear in a direction substantially parallel to said selected direction;

d. said wall having a front opening between said inner and said outer surfaces, said front opening being located to the rear of said front edge;

e. said wall having a rear opening between said inner and outer surfaces, said rear opening being located to the rear of said front opening and to the front of said stop surface;

f. a lever pivotally mounted on said outer surface for pivoting about the axis that extends parallel to said inner surface and transversely to said selected direction, and that is located to the rear of said front opening;

g. said lever having a front and a rear respectively positioned adjacent said front and rear openings;

h. means engaging said lever for urging said front of said lever away from said outer surface and said front opening, and for urging said rear of said lever toward said outer surface and said rear opening;

i. at least one electrical contact mounted oN said front of said lever and extending therefrom toward said front opening;

j. and an operating cam positioned on said rear of said lever and extending therefrom through said rear opening and inwardly of said receptacle beyond said inner surface so as to be engaged by a surface of a radio to cause said lever to pivot about said axis so that said front of said lever moves toward said outer surface, and its contact passes through said front opening sand engages a corresponding terminal on said surface of said radio;

k. said radio having a corresponding shape for being guided by said keying projection when inserted in said receptacle, and for being stopped during insertion by said stop surface on said keying projection.

2. The improved device of claim 1 wherein said electrical contact is resiliently mounted on said lever.

3. The improved device of claim 1 wherein said urging means comprise a compression coil spring positioned between said lever and said outer surface.

4. The improved device of claim 3 wherein said electrical contact is resiliently mounted on said lever.
