11.5 AMP CONNECTOR

Applying Silicone Dielectric Compound to
AMP Connectors
Silicone Dielectric Compound must be used on the AMP
connections for the following reasons:
• To prevent oxidation at the mechanical joint between
male and female pins.
• To prevent electrical malfunction caused by low level
conductivity between pins when wet.
Use the following procedure to apply Silicone Dielectric
Compound to the electrical connectors.
1. To prevent oxidation and low level conductivity, sili-
cone dielectric grease must be packed completely
around male and female pins on the inside of the
connector after the mating of the housing to the
header. This is easily achieved by using a syringe to
fill the header with silicone dielectric compound, to a
point just above the top of the male pins inside the
header. When assembling the housing to the
header, it is possible that the housing will become
air locked, thus preventing the housing latch from
engaging.
2. Pierce one of the unused wire seals to allow the
trapped air inside the housing to escape.
3. Install a hole plug into this and/or any unused wire
seal that has silicone dielectric compound escaping
from it.

Check to be sure the wedge lock is in the open, or
asshipped, position (See Figure 11-5). Proceed as follow:

1. To insert a contact, push it straight into the appropri-
ate circuit cavity as far as it will go (See Figure 11-7).
2. Pull back on the contact wire with a force of 1 or 2
lbs. to be sure the retention fingers are holding the
contact (See Figure 11-7).
