Abstract

A terminal connector assembly is disclosed, for joining a connector plug or the like to a multi-conductor shield and cable. The assembly comprises first and second backshell housing members. The first or forward housing member has a closed tubular configuration at its forward end, joinable with the connector plug. The remote portion of the housing is of partial tubular configuration, preferably semi-cylindrical, and has a threaded portion at its remote and extremity. A second backshell housing is complementary to the partial tubular configuration of the first housing member and interfits closely with it, having a complementary threaded portion at its end extremity. A tubular sleeve is insertable laterally into the open side of the backshell member. The sleeve houses clamping rings securing the shielding braid of the cable. The construction allows the braid to be engaged and clamped prior to lateral installation of the sleeve within the backshell housing. Preparation of the general assembly is greatly expedited and improved. Improved EMI/RFI radiation shielding is provided by locating the sleeve to bridge the area adjacet the threaded portion of the housing.

Claims

1. A terminal connector assembly for joining a connector plug or the like to a multi-conductor shielded cable having a shielding braid, which comprises

(a) a first backshell housing member having a closed tubular configuration at its forward end portion and being joinable at said end with a connector plug or the like,

(b) said first backshell housing member having a remote end portion of partial tubular configuration including an unthreaded portion joining a threaded portion at the remote end extremity,

(c) a second backshell housing member complementary partial tubular configuration to the remote end portion of said first housing member adapted to interfit with said remote end portion of the first housing member to form a closed backshell housing assembly,

(d) said second housing member having a threaded portion at its remote end extremity complementary to said first mentioned threaded portion and forming therewith a cylindrical threaded end of the assembled housing parts,

(e) a tubular sleeve insertable laterally into the open side of said first backshell housing member and secured therein upon assembly of said second backshell housing member,

(f) said sleeve having a central passage and having an internal shoulder defining an opening for the reception of said cable,

(g) one or more clamping rings received over said cable and positioned within said sleeve for clamping engagement with the shielding braid of said cable,

(h) a threaded collar receivable over the threaded remote end of the assembled housing parts for securing said parts in assembled relation, and

(i) shoulder means limiting forward movement of said sleeve in the backshell housing,

(j) at least one of said clamping rings having a remote end portion engageable by said threaded collar for urging said clamping rings into a compression relationship with said sleeve.
