1. INTRODUCTION

Terminating Head 58392–1 (shown in Figure 1) is

designed to terminate discrete wire in MTA Quad IDC

connectors with or without polarizing tabs. Slotted

high–current contacts for insulation displacement

termination are pre–assembled on 3.96–mm

[.156–in.] centerlines in each color–coded housing for

a specific wire size.

The head must be installed in Pistol Grip Manual

Handle Assembly 58074–1, Pistol Grip Pneumatic

Handle Assembly 58075–1, or Pneumatic Bench

Power Assembly 58338–1. For head installation and

removal, refer to Instruction Sheet 408–6790 for the

manual handle assembly, 408–6789 for the

pneumatic handle assembly, or 408–9393 for the

bench power assembly.

For detailed connector description and application

requirements, refer to Application Specification

114–1048.

Read these and all referenced instructions thoroughly

before using the head.

All numerical valuesin thisinstruction sheet are

in metric units[with U.S. customary unitsin

brackets]. Dimensions are in millimeters [and

inches]. Figures are not drawn to scale.

2. DESCRIPTION

The head serves as a guide and support for the

connector during termination. Features of the head

(shown in Figure 1) and their function are as follows.

Wire Inserter — forces the wire into the two slotted

beams of the contact. Note that it provides support for

the contact beams when applying insertion force on

the wire.

Adjuster (Insertion Rod) — is a piston for the wire

inserter and regulates wire inserter travel.

Feed Slide — automatically positions the connector

after each termination.

Locating Pawl (or Anti–Backup Pawl) — aligns the

connector for insertion, and retains it during

termination.

3. SETUP AND TEST INSPECTION

The adjuster (insertion rod) is preset for wire sizes 22

through 18 AWG. If the wire is being inserted too

deeply or not deeply enough inside the contact, it may

be necessary to adjust the depth of the wire inserter

or, in addition, if the pneumatic handle assembly is

being used, it may be necessary to adjust the air

pressure. Proceed as follows:
