introduces the basic knowledge of open-ring

In the Goowell wiring harness factory, the open-ring terminal is the most common type of terminal, so it also has a very mature crimping process and some known common problems. As a professional wiring harness factory, all employees are familiar with these processes It must be learned and mastered, and it can be controlled calmly in product design and quality improvement.

First, it helps to understand that a terminal has three main parts: the mating area, the transition area, and the crimping area.

As the name suggests, the mating area is the part where the terminal mates with the other half of the connection terminal.

This part is designed by the connector designer Designed to engage mating terminals and work in a certain way.

If the mating part is deformed during the crimping process, it will degrade the performance of the connector.

Analysis of open-ring terminal structure

The transition area is also designed to be unaffected during the crimping process.

If you change the position of the spring tab or terminal lip, it will also affect the performance of the connector.

The crimping area is the only part of the design that is affected by the crimping process.

Use The termination equipment recommended by the connector manufacturer, clamps the crimp area so that it is securely connected to the wire. Ideally, all of the work you do to crimp the terminal to the wire occurs in the crimp area only.

Insulation crimping Compresses the insulation in the crimp area, but does not puncture it.

The core (or wire brush) protrudes beyond the front of the conductor crimp area a distance at least equal to the diameter of the cable conductor.

For example, a 1.02mm (18 AWG) cable should protrude At least 0.40".

Insulation and conductors are visible between the insulation and conductor crimp areas.

The conductor crimp areas are flared at the lead-in and tail ends, while the transition and splice areas remain the same before and after the crimping process. Change.

The wires used in Goowell 's main wiring harnesses are: Japanese standard wires (AVSS, AVS, AEX), German standard wires (FLRY-A, FLRY-B), American standard wires (AWG, SAE, J1128), national standard wires (QVR/ GB).

Wires of different standards have different D (outer diameter), d (insulation layer thickness), R (single wire diameter) and the number of strands of wires. Standard.

The wiring harness produced by our company is in accordance with the IPC620 certification standard to ensure quality.
