MIL-DTL-83538 Connectors And Accessories, Electrical, Circular, Umbilical, Environment Resistant, Removable Crimp Contacts For Mil-Std-1760 Applications \(Metric\), General Specification ForThis specification covers connectors and accessories, electrical, circular, umbilical. The connector assembly provides the necessary connections required to meet MIL-STD-1760, class I electrical interface between stores and their associated launchers using a "blind mating" mechanism. The connector assembly consists of a receptacle installed on the launcher, a receptacle installed on the store, and a buffer plug installed between the two receptacles. This specification also includes the required mounting adapters and nut, accessory adapter, cable bushing, and protective covers \(see 6.1 for details on intended use and application\). The connectors covered by this specification are intended for use with launcher mechanisms with an applied holding force in the range 271 Newtons \(61 lbs\) to 427 Newton \(96 lbs\).

1.2 Physical characteristics. The connector assembly (see figure 1) consists of a launcher receptacle,

MIL-DTL-83538/4, buffer plugs, MIL-DTL-83538/3 and MIL-DTL-83538/11, and a store receptacle, MIL-

DTL-83538/1. In addition, there are connector caps to protect the launcher receptacle and the store

receptacle after they have been installed on launchers and stores and are not mated with the buffer plug.

The launcher receptacle cap, MIL-DTL-83538/8, meets all the environmental and retention requirements

that apply to the buffer plug. The store receptacle cap, MIL-DTL-83538/7, meets the sand and dust

requirement (see 3.36). The launcher receptacle accessory adapter, MIL-DTL-83538/9, mates with the

same accessories in accordance with MIL-DTL-38999, series III and as specified in SAE-AS85049.

1.2.1 Contact styles:

Connectors used with standard contact arrangements as specified in MIL-STD-1560, are as follows:

P - Pin: Buffer plug only (nonremovable).

S - Socket: Receptacles only (Crimp, removable).

L - No contacts are provided with the receptacle.

The "P" or "S" designators are used to indicate that connectors will be used with full complements of

the applicable standard contacts as specified in MIL-STD-1560.

Receptacles accommodate crimp removable contacts "(S)" and may be ordered without standard

contacts by using an "L" designator.
