Electrical connector for a microphone

DETAILED DESCRIPTION An object, therefore, of the invention is to provide a new and improved electrical connector for mounting a microphone of the disc type which has opposite flat faces joined by a cylindrical periphery.
In the exemplary embodiment of the invention, the connector includes a dielectric housing having a generally cylindrical microphone insertion cavity defined by a rigid arcuate wall portion at one side of the cavity and a flexible wall portion at an opposite side of the cavity.
The distance between the rigid arcuate wall portion and the flexible wall portion is less than the diameter of the disc shaped microphone so that the flexible wall portion resiliently engages the cylindrical periphery of the microphone to establish an interference fit therewith.
Generally, terminal means project into the cavity for engaging appropriate terminals on the microphone.
As disclosed herein, the rigid arcuate wall portion of the cylindrical microphone insertion cavity extends approximately 180.
degree.
about the circumference of the cavity.
The flexible wall portion is formed by a cantilevered arm having a length on the order of the depth of the cavity which, preferably, is less than the width of the cylindrical periphery of the microphone between the opposite flat faces thereof.
The cantilevered arm has a radially inwardly directed projection near a distal end thereof for engaging the cylindrical periphery of the microphone.
The terminal means include at least one flexible terminal located in the bottom of the cavity and projecting inwardly thereinto.
A stop shoulder is formed in the cavity for limiting the insertion depth of the microphone to prevent overstressing the flexible terminal.
As disclosed herein, the one flexible terminal projects radially into one side of the cylindrical cavity generally on a diameter thereof for engaging the center positive terminal of the microphone.
The stop shoulder is generally C-shaped about the terminal.
A second terminal projects generally tangentially into the cylindrical cavity for engaging the negative metal shell at the periphery of the microphone
