The causes and consequences of poor crimping of electronic wire harnesses?

For you to explain the electronic wire harness cutting process and crimping process, this article is mainly to explain the causes and consequences of electronic wire harness crimping bad, see the following bad cases; 1. skin crimping excessive bad reason: crimping gesture is incorrect or improper debugging of the baffle plate leads to the core wire crimping parts pressed into the outer skin, resulting in excessive bad skin crimping. Consequences: directly affect the conductor crimping, resulting in poor current flow or direct disconnection.

2. Reasons for insufficient crimping of the outer skin: incorrect crimping gesture or crimping speed is too fast resulting in poor crimping. Consequences: due to the conductor and insulation part of the crimping are insufficient, resulting in the terminal tension is not enough, in the process of using the product is easy to break, directly affecting the performance of the product.

3. The reason for the exposed copper wire is bad: in the process of crimping, the semi-finished copper wire is scattered, or the crimping method is improper. Consequences: the exposed copper wire is easy to cause discharge, but also easy to contact with other terminals resulting in a short circuit. Core wire crimping parts due to less copper wire, indirectly affect the tension of the terminal, resulting in insufficient tension.

4. The reason why the outer skin wrapping foot breaks badly: when the mold is debugged, the terminal is not in place, or the crimping blade is damaged. Consequences: directly affect the pulling force.

5. apex cut flat bad reason: terminal crimping position and mold cut off knife position is not debugged, or the terminal delivery grip is not stable. Consequences: cause the terminal and the pair of inserts is difficult to match.

6. The rear end of the cut long bad reason: terminal crimping position and mold cut off the position of the knife is not debugged, or the terminal delivery grip is not stable. Consequences: the back end of the long, it will cause the front end cut flat, the consequences and the same as point 5, in addition to the back end of the long easy to contact with other metal objects, resulting in a short circuit of the line, the consequences are also very serious.

7. Rear end without flare bad reason: core wire crimping blade adjustment is not in place. Consequences: the blade is easy to hurt the core wire, so that the tension of the terminal will be small, affecting the service life of the terminal.

8. Reasons for bad bayonet twisting and deformation: bad raw materials, bad crimping, or hooking and pulling each other in the process of product movement. Consequences: cause assembly is not close, not in place, the product to the customer is easy to fall off.

9. Terminal warping or bending bad reason: mold debugging, the upper and lower mold with bad, or die piece sticky terminals. Consequences: poor assembly fit, the terminal is easy to fall out of the socket.

10. No core wire crimping bad reason: by stripping the head short caused by no core wire crimping, generally appear in the fully automatic crimping bad more. Consequences: not conductive, directly affecting the conductivity of the product.

11. Front end core wire is too long bad cause: stripping head is too long or crimping gesture is not correct. Consequences: the core wire is too long and easy to contact with the side of the terminal causing a short circuit, the protruding core wire is easy to put the socket bayonet top up, resulting in the assembly of the insertion of insufficient, the wire is easy to fall out of the socket.

12. Reason for poor deformation of the contact area: Damage to the terminal crimping die or misalignment of the blade. Consequences: Assembly does not fit into the socket when assembled, and even if it is inserted, there is no pulling force, commonly found on VH-T terminals.

13. Reason for poor terminal stacking: when crimping in the continuous pressure machine, the wire moving speed and crimping speed are not consistent. Consequences: the product can not be used, easy to make the mold, die sheet damage.
