7.4 AMP CONNECTOR
Applying Silicone Dielectric Compound to AMP
Connectors
Silicone Dielectric Compound must be used on the AMP con-
nections for the following reasons:
• To prevent oxidation at the mechanical joint between male
and female pins.
• To prevent electrical malfunction caused by low level con-
ductivity between pins when wet.
Use the following procedure to apply Silicone Dielectric Com-
pound to the electrical connectors.
1. To prevent oxidation and low level conductivity, silicone
dielectric grease must be packed completely around
male and female pins on inside of connector after mat-
ing housing to the header. This is easily achieved by
using a syringe to fill header with silicone dielectric
compound, to a point just above the top of the male
pins inside the header. When assembling housing to the
header, it is possible the housing will become air locked,
preventing housing latch from engaging.
2. Pierce one of the unused wire seals to allow trapped air
inside housing to escape.
3. Install a hole plug into this and/or any unused wire seal
that has silicone dielectric compound escaping from it.
Assembly
Make sure wedge lock is in the open, or as-shipped, position
(See Figure 7-5.). Proceed as follows:
1. To insert a contact, push it straight into the appropriate
circuit cavity as far as it will go (See Figure 7-7.).
2. Pull on contact wire with a force of 1-2 lbs to be sure
retention fingers are holding contact (See Figure 7-7.).
