How to Vertically Insert Prepared Wire into the Terminal Barrel of a Crimping Tool for Cold Press Pins？
To vertically insert prepared wire into a cold-pressed needle crimping device, hold the stripped wire at a precise ninety-degree angle to the terminal barrel opening. Lower the conductor strands straight down into the center of the barrel until the wire insulation rests gently against the top edge. This prevents the wires from loosening and ensures a stable mechanical fixation.
Essential Specifications for Wire Preparation
Accurate stripping dimensions prevent structural damage during execution. Workers must match the stripped conductor length exactly to the depth of the specific terminal sleeve. The technical data table below outlines standard industrial dimensions required for precise vertical entry before utilizing a standard contact crimper to finish the assembly.
| Wire Gauge (AWG) | Strip Length (mm) | Insulation Diameter (mm) |
|---|---|---|
| 20 | 4.0 | 1.8 |
| 22 | 3.5 | 1.5 |
| 24 | 3.0 | 1.2 |
Standard Operating Procedure for Insertion
Sequential Execution Steps
-
Secure the terminal barrel. Place the uninsulated metal contact inside the correct die nest of the d sub contact crimper. Maintain slight pressure on the tool handles to hold the component steady without causing structural deformation. Ensure the barrel opening points directly upward to receive the wire.
-
Align the wire vertically. Guide the stripped conductor straight down along the center axis of the cold-pressed needle crimping device. Keep the wire perfectly perpendicular to the tool to prevent the outer copper strands from catching on the rim, avoiding loose wires outside the joint.
-
Complete the compression cycle. Push the wire downward until the insulation jacket rests against the top rim of the barrel. Squeeze the handles firmly until the ratchet mechanism releases automatically. Consistent contact crimping relies on keeping the assembly perfectly stationary during this step.
Quality Verification
A successful connection leaves zero exposed copper strands outside the rear of the terminal. Following structured vertical techniques preserves the physical integrity of electrical systems and eliminates common field failures. Checking the final pull strength regularly confirms that the finished terminal holds firmly under extreme operational stress.
