Bad terminal crimping factors (1)

Front and back position deviation

In the event of a backward deviation:

1. The effective pressing area is reduced: the resistance will rise and the tensile strength will weaken.

2. No front side bell mouth: terminal deformation and cracks such as humpback are prone to occur.

3. No cut-off on the rear side: Deformation of the insulating grip.(Especially the terminal end delivery (direct delivery) terminal)

4. Too many cut-offs on the front and rear sides: In the case of direct-feeding terminals, it will be difficult to insert the shell or lead to poor mating with the opposite side.

In the event of a deviation to the front:

1. The effective pressing area is reduced: the resistance rises and the tensile strength weakens.

2. There is no rear side bell mouth: the wire is broken from the edge of the conductor grasping part. (Even if there is no problem when pressing, I am afraid it will be disconnected in the future)

3. Without front cut-off: In the case of direct feeding terminal, the mating part will be damaged.
