MIL-DTL-21617B
4.5.11 Insert retention (see 3.6.10). Connector inserts shall withstand a uniformly distributed axial load
of 60 pounds (27 kg) in either direction without being dislocated from their normal position in the connector
shell. The insert assembly shall retain its normal position in the connector shell for the specified load the
following condition shall apply:
a. The load shall be increased gradually at a rate of approximately 1 pound (0.45 kg) per second
until the specified load is reached.
4.5.12 Resistance to test prod damage (see 3.6.11). Socket contacts shall be tested in accordance
with test procedure EIA-364-25. The following details shall apply:
4.5.12.1 Initial test. Eight (8) size 16 socket contacts shall meet the requirements of contact separation
(see 3.5.9) after having been subjected to the following test:
a. A test prod of hardened steel having a diameter equal to a nominal mating pin shall be inserted
into each socket to .50 inch (12.7 mm), .375 inch (9.53 mm), and .25 inch (6.35 mm) depth.
b. At each of these depths, measured from the face of the insert, a bending moment of 2 pound -
force inch (226 mN m) ±10 percent shall be applied to the prod, about the inserted end of the
prod, and the connector shall be rotated in one direction through 360°, in order that a uniform
force is applied to the inside surface of the socket.
Note: This test shall be performed with the socket contacts in their inserts, and the sockets locked, if
necessary, to prevent rotation in the inserts during the test.
4.5.12.2 Test procedure for resistance to test prod damage. In order to insure uniform test results, the
test fixture shown in the appendix shall be used to perform the tests required by 3.6.11. Procedures shall
be as follows:
a. With the weight in position for the 2 inch-pound moment and no spacers on the pin, insert the pin
in a socket of an assembled receptacle or plug while the axis of the socket is in a horizontal
position.
b. With the fixture free and unsupported, rotate the receptacle or plug 360° about a horizontal axis,
maintaining the socket in a horizontal position.
c. Repeat with size 1 spacer.
d. Repeat with size 2 spacer.
e. After withdrawal of the fixture, the socket shall pass the contact separation force requirement of
