Abstract
A field installable backshell connector for a shielded cable provides an EMI shield around control signal conductors and a plastic connector of the cable and also provides a mechanical terminal of the cable. The backshell connector provides a low impedance ground path from the cable shield to a connector socket. The connector socket includes a plastic connector header that is shielded by a grounded metal shroud. When connected to the socket, the backshell is abutted with the connector socket shroud to complete the low impedance ground path from the cable shield in order to shunt electrical noise introduced on the cable shield, connector backshell and shroud to ground to resist electrical interference.
Claims18
A cable connector backshell comprising:
- a metallic shell comprising a base, a cover connected to said base, and a recess located between said cover and said base;
- a connector opening that opens through said shell into a first portion of said recess;
- a mouth that opens through said shell into a second portion of said recess, said mouth adapted for passage of an associated cable terminal end into said recess;
- first and second flanges located adjacent a first end of said shell and projecting laterally outward from said shell, said first and second flanges adapted to be engaged by respective first and second fasteners for releasably securing said shell to an associated connector socket;
- said first portion of said recess located adjacent said connector opening comprising a connector seat located between first and second spaced-apart side walls of said base, said connector seat adapted to receive and support an associated plug connector located on the associated cable terminal end such that a projecting plug portion of the associated plug connector projects through said connector opening;
- said shell further comprising a portion located in said recess and adapted for contacting an electrical shield surrounding the associated cable terminal end and electrically connecting the electrical shield to the shell.
A backshell for a cable connector, said backshell comprising:
- a metallic shell comprising a base and a cover connected to said base, said shell comprising a recess;
- said shell including a connector opening that opens through said shell into said recess;
- said shell further including a mouth that opens through said shell into a said recess, said mouth adapted for passage of an associated cable terminal end into said recess;
- first and second flanges projecting laterally outward from said shell in opposite first and second directions, respectively, said first and second flanges adapted to make electrical contact with an associated connector socket;
- a floor of said shell defining a connector seat in said recess between first and second spaced-apart side walls, said connector seat adapted to support an associated plug connector located on the associated cable terminal end and said connector opening of said base adapted to receive a projecting plug portion of the associated plug connector supported on said seat;
- said shell further comprising a portion adapted for contacting an electrical shield surrounding the associated cable terminal end located in said recess and electrically connecting the electrical shield of the associated cable to the shell such that said shell defines an electromagnetic interference shield around the associated cable terminal end located in said recess.
A cable connector backshell assembly comprising:
- a metallic shell comprising a base, a cover connected to said base, and a recess located between said cover and said base;
- said shell including a connector opening that opens through said shell into a first portion of said recess and including a mouth that opens through said shell into a second portion of said recess;
- first and second flanges located adjacent a first end of said shell and projecting laterally outward from said shell, said first and second flanges adapted to be engaged by respective first and second fasteners for releasably securing said shell to an associated connector socket;
- said recess comprising a connector seat located between first and second spaced-apart side walls of said base, said connector seat adapted to receive and support an associated plug connector located on an associated cable terminal end such that a projecting plug portion of the associated plug connector projects through said connector opening;
- said shell further comprising a portion adapted for contacting an electrical shield surrounding the associated cable terminal end and electrically connecting the electrical shield to the shell.
