ABSTRACT:
A low cost antenna mount is disclosed for mechanically securing an antenna to an electronic device and simultaneously providing assurance of good electrical contact with the input circuitry of the device. An antenna base (1) with a machined groove (2) is inserted through a hole (4) in a molded plastic antenna housing (5). An integral electrical contact and cam follower (7) is secured to the interior of the antenna housing (5). A cam (15) is used for moving the integral electrical contact (7) and cam follower (7) into mechanical and electrical contact with the antenna base (1). The cam follower (7) is formed from a single strip of spring metal and is bent at three places to form a guide (6) for receiving the antenna base (1) as it is inserted into the hole (4) in the antenna mount. The cam follower (7) is biased to follow the inclined surface of the cam (15) as it is rotated to securely lock the antenna base (1) in place and simultaneously make good electrical contact therewith. The distinguishing characteristics of the invention are the ease of installation and removal of the antenna to electrical circuitry such as a radio or other communications device and the simplicity of its structure. An integral electrical contact (11) at one end of a cam follower (7) and a cam (15) are the major parts of this invention. The cost of manufacture is minimized by using such a simple structure, and reducing the number of parts and the number of operations required for assembly.
