Terminal Components Guide

Comprehensive guide covering socket, tab, and PCB terminals, their specifications, and proper installation techniques for all connector series.

Understanding Terminal Components

What are Terminals?

Precision-formed metal contacts that crimp onto wires or mount to PCBs, providing the electrical connection within connector housings.

Why Different Types?

Different orientations and mounting requirements demand specific terminal designs to ensure proper fit and reliable connections.

Naming Convention

Suffix codes (FR, VR, VS, VT, FT, PC) identify terminal types, with F=flat, V=vertical, R=receptacle, S=socket, T=tab, PC=PCB mount.

Installation Guide

Terminal Installation Process
Follow these steps for proper terminal installation
1

Strip Wire

Strip wire insulation to 5-6mm length. Avoid nicking the conductor strands.

2

Insert into Terminal

Insert stripped wire fully into terminal crimp barrel until it bottoms out.

3

Crimp Terminal

Use proper crimping tool with correct die. Apply firm, even pressure until crimp is complete.

4

Insert into Housing

Push crimped terminal into housing until you hear/feel the lock engage.

5

Verify Lock

Gently pull wire to confirm terminal is fully locked in housing.

Terminal Removal Procedure
Use proper tools to avoid damage
  1. 1. Insert terminal removal tool into housing slot
  2. 2. Depress locking tang while pulling wire gently
  3. 3. Remove terminal once lock is released
  4. 4. Inspect terminal for damage before reuse

Common Mistakes to Avoid

Over-stripping Wire Insulation
Consequence: Exposed conductor can short circuit
Solution: Strip only 5-6mm of insulation
Under/Over-crimping
Consequence: Poor connection or wire damage
Solution: Use calibrated crimping tool
Forcing Wrong Terminal Type
Consequence: Housing or terminal damage
Solution: Verify terminal type matches housing
Not Verifying Terminal Lock
Consequence: Terminal can pull out during use
Solution: Always perform pull test after insertion
