Heavy-duty connector common faults: one needle withdrawal when inserting
Solution:
1. Poor pin guiding due to component defects. Generally, the trace of the male pin is squeezed at the mating end of the female pin.
2. Poor crimping causes the assembly to be out of position. At the crimping point, the crimping deformation is too large or curved, causing interference with the corresponding mounting hole, and cannot be assembled in place.
3. Other reasons lead to the assembly not in place. Due to the wire being too thin or the hole is too small, the assembly is not in place, etc.
4. Parts defects lead to unreliable support. Due to defects in components, such as the support platform of the insert, or the shrapnel on the pin, the support is not reliable.
Common problems with cold-pressed heavy-duty connectors: Second, poor contact
1, Effective contact distance, mating surface, the height of each pin should be basically the same. When checking the connector insertion, the insertion force is significantly increased to the distance of the insertion into position.
Generally, it is more than 2mm; at the same time, it is checked whether the heights of the pins of the mating surface are substantially the same, so as to eliminate the insufficient effective contact distance of the individual pins due to the defects of the individual pins.
2. Whether the female needle has a tight grip. Exclude by testing the tightening force one by one.
The needle is retracted. Exclude by checking whether the height of each pin of the mating surface is still substantially the same after the connector is inserted.
Heavy duty connector, industrial connector
If the height of the pin is obviously inconsistent after the insertion, it can be checked whether it is due to poor assembly, component defect, or poor orientation of the pin.
If it is caused by poor guiding, after the insertion, the male pin will leave a mark on the end of the female pin.
