Abstract
A connector assembly for effecting mechanical and electrical connection between a portion of a security alarm or similar circuit mounted on a swinging door or window and a portion of such a circuit located on fixed structure adjacent the door or window, including a resilient electrical cable mechanically connecting a pair of terminal housings which protectively cover the cable and terminals at the ends of the cable when the housings are located adjacent one another with the door closed. The housings may also enclose an electrical sensor, such as a magnetically actuated switch and an actuating magnet, electrically connected with the terminals, for connection with a security alarm circuit.
Claims16
A connector assembly for use in electrically connecting a first portion of an electrical circuit carried on a first structure which is reciprocally movable relative to a second structure to a second portion of said electrical circuit mounted on said second structure, said connector comprising:
- (a) an elastically extensible cable having a pair of opposite cable ends and including at least one electrical conductor, said cable having a relaxed configuration in which it has a predetermined relaxed length between said cable ends, and said cable being elastically extensible to a substantially increased length;
- (b) a first housing adapted for being fixedly mounted on said first structure, one of said opposite cable ends of said cable being attached to said first housing;
- (c) a second housing adapted for being fixedly mounted on said second structure, the other of said opposite cable ends of said cable being attached to said second housing;
- and
- (d) said first and second housings having matingly corresponding portions defining a cable cavity enclosing said cable with said cable in said relaxed configuration when said housings are mounted respectively on said first and second structures and said first structure is in a first position relative to said second structure, said housings being separated further from each other and said cable being elastically extended to an increased length when said first structure is moved to a second position relative to said second structure.
A combined switch assembly and connector for connecting one portion of a security alarm electrical circuit to another portion of such a circuit, comprising:
- (a) a first terminal housing, adapted for being mounted on a door and including means for defining a mounting place for a magnet;
- (b) a second terminal housing, adapted for being mounted on a doorway frame and including means for defining a switch cavity therein;
- (c) an elastically resilient cable having a pair of opposite cable ends and including at least one electrical conductor, said cable having a relaxed configuration in which said cable has a predetermined relaxed length, and said cable being elastically extensible to a substantially increased length, said opposite cable ends of said cable being fixedly connected respectively to said first and second terminal housings;
- (d) a magnetically actuated switch fixedly located within said switch cavity;
- (e) an actuating magnet fixedly attached to said first terminal housing in said mounting place;
- and
- (f) said first and second housings having portions cooperatively defining a cable cavity enclosing said cable, with said cable substantially in said relaxed configuration, when said housings are mounted respectively on said door and said doorway frame.
A combined switch and connector device for use in a security alarm circuit for protecting a door, comprising:
- (a) a first housing adapted for being mounted against a flat surface of a door, said first housing including a side wall, a front wall connected with and extending generally perpendicular to said side wall, and a pair of opposite end walls, each connected with and extending generally perpendicular to said side wall and said front wall;
- (b) a second housing adapted for being mounted in a doorway against a flat surface which is perpendicular to said door when said door is closed, said second housing including a side wall, a front wall connected with and extending generally perpendicular to said side wall, and a pair of opposite end walls each connected with and extending generally perpendicular to said side wall and said front wall of said second housing, said front walls and end walls of said first and second housings, respectively, being of corresponding size and fitting matingly together and said walls including surfaces defining a cable cavity between said first and second housings and said flat surfaces;
- (c) said side wall of said first housing including a terminal cavity therein, said terminal cavity being separated from said cable cavity by an inner wall member of said side wall, said inner wall member defining an aperture extending therethrough;
- (d) said front wall of said second housing defining a switch cavity therein, said switch cavity being separated from said cable cavity by an inner wall member thereof;
- (e) an elastically extensible cable having a pair of opposite cable ends and including at least one electrical conductor, said cable having a relaxed configuration in which it has a predetermined relaxed length between said cable ends, and said cable being elastically extensible to a substantially increased length;
- (f) a first terminal board having a plurality of terminal posts, located in said terminal cavity;
- and
- (g) a second terminal board having a plurality of terminal posts, located in said switch cavity.
