Abstract

A terminating potting backshell for connecting a wire or wire harness to a mating receptacle of an electrical/electronic device which is in the form of a generally tubular electrically conductive body and having threads encircling a first end for attaching the backshell to a mating receptacle on the electrical/electronic device and also having a groove spaced from a second end over which a conductive tubular braided shield can be disposed. The groove adapted to receive a clamp for holding the tubular braided shield onto the second end of the backshell.

Claims

1. A terminating potting backshell for connecting at least one conductor to a mating receptacle of an electrical/electronic device, said backshell comprising, a generally hollow, electrically conductive body having predetermined dimensions and open at each of two ends, threads encircling at least a portion of a first end for attaching said backshell to such mating receptacle on such electrical/electronic device, a groove having a predetermined cross-section, spaced closely adjacent a second end over which an end of a conductive braided shield can be disposed, and an adjustable clamp matingly engageable with an outer surface of said conductive braided shield for compressing said end of said conductive braided shield into said groove to hold said end of said braided shield onto said second end of said backshell, said clamp having a width substantially equal to a width of said groove such that said clamp and said braided cable enter said groove.

2. A terminating potting backshell, according to claim 1, in which said electrically conductive body is generally a cylindrical tubular body.

3. A terminating potting backshell, according to claim 2, in which said cylindrical tubular body is provided with a different diameter at each end thereof.

4. A terminating potting backshell, according to claim 2, in which said cylindrical tubular body is shaped substantially as an elbow.

5. A terminating potting backshell, according to claim 1, in which said groove has a substantially rectangular cross-section adapted to receive a clamp having a mating substantially rectangular cross-section.

6. A connection with an electric/electronic device comprising a backshell which encases at least one conductor connected to a connector, a non-conductive, substantially non-porous potting material disposed within said backshell, a braided conductive shield encasing said at least one conductor having an end connected to said backshell, threads encircling a first end of said tubular backshell for attaching said backshell to a mating receptacle on said electrical/electronic device and means engageable with an external surface of an end of said braided conductive shield for connecting said end of said braided conductive shield to a second end of said backshell, said means having a width substantially equal to a width of said groove such that said means and said braided cable enter said groove.

7. A connection, according to claim 6, in which said means for connecting said braided conductive shield to said second end of said backshell comprises a groove around a periphery of said backshell spaced from said second end over which said conductive braided shield is disposed and a clamp disposed around said conductive braided shield which compresses an end of said shield into said groove.

8. A connection, according to claim 7, in which said clamp comprises a shrink tube.

9. A connection according, to claim 7, in which said braided conductive shield is substantially tubular in form.

10. A connection, according to claim 7, in which said groove is generally rectangular in cross-section and said clamp has a mating generally rectangular cross-section.
