scope:

This specification relates to a range of multi-contact, circular, sealed plugs and sockets, electrical with threaded coupling, silver plated contacts and soldered terminations for d.c. and low frequency applications. Pattern 104 plugs and sockets are available in three basic types:

Type A - Aluminium shells with fine threaded coupling.

Type B - Brass shells with coarse threaded coupling.

Type C - Aluminium shells with coarse threaded couplings.

Outlets and accessories, which will provide sealing, screening and screen termination for use with the Standard Range of Pattern 104 plugs and sockets are also included in this Standard.

This specification gives details of dimensions, ratings, and test values peculiar to the standard range of items defined.

The Standard range of pattern 104, plugs and sockets are interchangeable and mateable with appropriate styles, sizes and orientations of the circular multi-contact plugs and sockets shown in Tables II and III, Defence Standard 59-4 Part 4, which superseded DEF 5321. The Pattern 104 Standard Range should first be considered when provisioning, for maintenance purposes, any of the Defence Standard 59-4(PART 4) items.

For connector cable assembly, reference should be made to DEF STAN 59-95 (Part 1) and Def Stan 59-95 (Part 1) Section 1.
