B. Colors
The (Terminal Position Assurance) TPA's on the plug and cap AMPSEAL 16 Connector Assemblies come in
colors to indicate mechanical polarization (keying).
C. Sealing
AMPSEAL 16 Connectors have two wire seal options for sealing to wires: Standard Diameter Wire Seal
(SDWS) and Reduced Diameter Wire Seal (RDWS). Wires having an insulation diameter of 2.18-3.67 mm
[.086-.144 in.] would use the SDWS. These wires would typically be in the 14-18 AWG range. Wires having
an insulation diameter of 1.30-2.54 mm [.051-.100 in.] would use the RDWS. These wires would typically be
in the 18-20 AWG range. Although the HDSF Size 16 contacts will accept a wire range size of 14-20 AWG,
and having an insulation diameter range from 1.27-3.94 mm [.050-.155 in.], only wires with insulation
diameters within the recommended wire seal range for this product should be used.
D. Cap and Plug Assemblies
Single and dual row cap and plug versions are available on 4.5 mm [.177 in.] centerline spacing between
circuits. A connector assembly consists of a plug assembly loaded with HDSF Size 16 socket contacts,
mated to a cap assembly loaded with HDSF Size 16 pin contacts or a printed circuit (pc) board mounted
“cap” assembly. Circuit identification is marked on each TPA and seal cover. Typically four different keying
configurations are available for each connector size (colors and mechanical).
An integral Connector Position Assurance (CPA) is designed on each plug assembly. Both plug and cap
assemblies have a terminal position assurance (TPA) feature to lock the contacts in the housings. A special
Contact/TPA Removal Tool (P/N 776441-1) is required to remove the TPA and contacts. See Section 5,
TOOLING. Sealing plugs are available for unused circuits. The plug and cap assemblies also provide
moisture resistance through the use of wire seals and a peripheral seal in the interface area.
3.3. Assembly Procedure
CAUTION
The seal cover must not be removed or altered in any way.
CAUTION
The rear of the connector must be completely sealed. Cavities that are not loaded with wires must be blocked using seal plug
(part number 776363-1) for SDWS and RDWS.
NOTE
Contact retention features in the plug and cap assemblies will not engage if the contacts are inserted into those assemblies
while the TPA is in the “locked” position.
A. Assembly
Crimped contacts (Refer to Application Specification 114-13045) shall be manually loaded into the housing
assemblies. Socket contacts shall be loaded into plug assemblies, while the pin contacts shall be loaded into
the cap assemblies. Refer to Figure 2 and insert the contacts into the housings assemblies with the
information as follows:
1. Verify that the TPA is in the pre-staged position (un-locked
). To verify the plug assembly TPA is in the
correct position, check the distance from the cover to the mating face of the TPA as shown in Figure 2
(there will be clearance between the seal and the TPA as illustrated. The location of the TPA for the cap
assembly should be as shown in Figure 2 when in the pre-staged position.
