Abstract

The cable shield termination backshell connects to a shielded cable havingndividually shielded conductors to prevent electromagnetic interference and electromagnetic pulses (EMI/EMP) from entering therein. The backshell has a groove thereabout having a plurality of holes therethrough. The individual braid ends, pigtails, are passed through the holes. An appropriate ring is placed over the groove and the braid ends and compressed thereon. The braid ends remaining exposed are cut off. The outer braid on the cable is attached to the end of the backshell with a ring and then the overall backshell is covered by a boot.

Claims

1. A cable shield termination backshell for connecting to a shielded cable having at least one shielded conductor therein, said cable shield termination backshell comprising:

a first housing, said first housing having a braid end groove on an exterior surface thereabout, said groove having at least one hole therethrough;

a second housing, said second housing being an integral part of said first housing, said second housing having thereon means for connecting to the shielded cable;

a connecting sleeve, said connecting sleeve rotatably connected to said first housing on an end opposite to said second housing;

means for providing electrical connections, said means for providing electrical connection being located in the end of said first housing with said sleeve thereabout;

an internal shield termination ring, said internal shield termination ring being located in said braid end groove; and

a cable shield termination ring, said cable shield termination ring being located about said second housing to secure the cable shield thereto;

whereby the shielded conductors enter into the first housing, the shield about each conductor being partially removed to expose a conductor, the removed shield being formed into a pigtail braid end, each braid end being placed through the holes in the braid end groove and secured thereon by said internal shield termination ring, the exposed conductor being connected to said means for providing electrical connections.

2. A cable shield termination backshell as defined in claim 1 wherein said holes in said braid end groove are uniformly distributed about said braid end groove

3. A cable shield termination backshell as defined in claim 1 wherein said first housing further includes a boot groove thereabout.

4. A cable shield termination backshell as defined in claim 3 wherein said boot is placed partially about said first and said second housings to prevent environmental contamination, said boot covering said internal shield termination ring.
