Crimping Procedure - TE Connectivity PRO-CRIMPER III Instruction Sheet

CRIMPING PROCEDURE

NOTE
This tool is provided with a crimp adjustment feature. Initially, the crimp height of a sample terminal should be verified in
accordance with Section 5.
1. Refer to Figure 1 and select wire of the specified size and insulation diameter.
Strip the wire to the length indicated in Figure 1, taking care not to nick or cut wire strands.
2. Hold the tool so that the back (wire side) is facing you. Squeeze tool handles together and allow them
to open fully.
3. Place the terminal in the proper crimping chamber (match color code to terminal insulation) so the
edge of the insulation aligns with the edge of the indenter. Note: The wire barrel should be at the back
of the tool.
4. Hold the terminal in position, and squeeze the tool handles together until ratchet engages sufficiently
to hold the terminal. DO NOT deform the wire barrel.
5. Insert the stripped wire into the wire barrel and holding the wire in place, squeeze the tool handles
together until the ratchet releases.
Allow the tool handles to open and remove the crimped terminal.
6. Inspect the terminal crimp height according to Section 5.
CRIMP HEIGHT INSPECTION
This inspection requires the use of calipers. A lead rod can be used to check the crimp height. Crimp a rod in
each of the crimping chambers. Check the crimp height of the rod against the crimp height dimension given in
Figure 4.
Lead Rod Diameter
If the crimp height conforms to the dimension, the tool and die assembly are considered dimensionally correct.
Lubricate the tool with a thin coat of any good SAE 20 motor oil. If it does not, adjust the crimp height according
to Section 6. If the adjustment does not result in an acceptable crimp height, the die assembly or tool may have
to be replaced.
