Designed for external installation, the XAC is
the MRAC removable contact connector
equipped with protective shells and mounting
plates for chassis or cable mounting on metal
containers, bulkheads, or any outside surface
equipment. Lighter and smaller than other
external connectors, they provide dependable
service under adverse conditions. Inserts are
housed in protective shells and there is screw
lock coupling of plug and receptacle.

DEFINITIONS OF
CONNECTOR TERMS
Plug:
The complete connector half which
has the plug shell as part of its assembly.
Receptacle:
The complete connector half
which has the receptacle shell as part of its
assembly.
Shell:
The metal housing in which a male or
female insert is assembled. A shell is either a
plug shell or a receptacle shell:
Plug Shell - one which is designed to be
inserted into a receptacle shell.
Receptacle Shell - one which is designed
to receive and enclose the plug shell upon
engagement.
Male Insert:
The molded insulator body
containing pin contacts.
Female Insert:
The molded insulator body
containing socket contacts.
Pin Contacts:
Male Contacts that fit into the
socket contacts.
Socket Contacts:
Female Contacts tubular
in shape, which receive the pin contacts and
retain them by spring tension.
Polarization:
A means of controlling the
engagement of a plug and receptacle so that
correct mating of the contacts is achieved.
Accessories:
Those components such as
hoods and mounting plates which are
attachable to a plug or receptacle to facilitate
mounting and/or handling of the connector,
and to prevent inadvertent cross-mating.

SPECIFICATIONS
Turnable jackscrew-jacksocket combination (M,
C, or D) assembles on either Plug or Recep-
tacle; the mating connector-half (either
Receptacle or Plug) must then contain fixed
jackscrew-jacksocket combination (F).
Both short and long turning jackscrews (M and C)
have knurled and slotted knobs for locking by
hand or screwdriver. Knob is assembled on shaft
with hollow, removable, self-locking pin. Safety
wiring of engaged halves is achieved by using
the through-hole in self-locking pin in the knob.
Monojacks (D) are long turning one-peice
locking devices with slotted and knurled head.
Shaft has through-hole for safety wire.
available with hoods only, in sizes 34, 42, 50,
66, 75, and 104.
Drawings show extension of standard knobs
beyond shell and beyond hood.
APPLICATIONS
Jackscrew locking device assures positive
coupling of engaged connectors to prevent
accidental disconnecting from vibration or
physical shock. It also aids easy connection
and separation of connector plug and
LOCKING DEVICE
receptacle. Mounted connector-half houses
one non-turnable fixed jackscrew and
jacksocket to insure connector polarization.
Mating-half houses one of the three types of
turning jackscrew and jacksocket (M, C, or D).
Note 1: Weights are for pairs; i.e. for a
jackscrew and jacksocket, etc., so
weight figure may be added once to
weights of other accessories when
computing total weight of plug or
receptacle.
Note 2: Weights of turnable jack-
screws and turnable jacksockets
include knob and rollpins, except
mono-jackscrew and mono-jacksocket,
which is a one-piece construction (shaft
and knob made in one piece); weight of
fixed jackscrew and jacksocket
includes nuts.
