Crimping apparatus
View Patent ↗The present invention provides a crimping apparatus that can adapt widely to various diameters of the insulating coatings of wires. The crimping apparatus has a crimp height adjustment mechanism for an insulating coating of a wire, the front of the crimping apparatus facing in a direction opposite to the direction of a core of the wire. The adjustment mechanism includes a shaft member having a regular polygon part and an eccentric shaft part that are connected thereto, and an adjustment dial which is disposed in the eccentric shaft part so as to face in the same direction as the front of the crimping apparatus. Therefore, this crimping apparatus can perform the crimping of terminals having various diameters of the insulating coatings of wires.
1. A crimping apparatus having a crimp height adjustment mechanism for an insulating coating of a wire, the front of the crimping apparatus facing in a direction opposite to the direction of a core of the wire,
wherein the adjustment mechanism comprises a shaft member having a regular polygon part and an eccentric shaft part that is connected to the regular polygon part and that has a center axis that is offset from a center axis of the regular polygon part, and an adjustment dial which is disposed on the eccentric shaft part so as to face in the same direction as the front of the crimping apparatus and which has a polygon outer circumference, the adjustment dial being disposed to operatively abut an insulation crimper on one side of the polygon outer circumference.
2. The crimping apparatus of claim 1 , wherein the crimp height adjustment is positioned on an applicator that is operatively associated with a press ram.
3. The crimping apparatus of claim 2 , wherein the applicator has a wire crimper having a bottom dead center position, the bottom dead center position being adjustable by a dial on the press ram.
4. The crimping apparatus of claim 3 , wherein the wire crimper, at an upper edge thereof, abuts against a surface fixedly attached to the press ram.
5. The crimping apparatus of claim 1 , wherein the distance between a center axis of the adjustment dial and the polygon outer circumference of the adjustment dial varies along the polygon outer circumference.
6. The crimping apparatus of claim 1 , wherein the adjustment dial has a plurality of concavities positioned between successive sides thereof, the eccentric shaft part has a pin extending therefrom, and the adjustment dial is biased relative to the eccentric shaft part to engage the pin in one of the concavities.
7. The crimping apparatus of claim 2 , wherein the regular polygon part is fitted into a matched concavity, in the applicator.
8. The crimping apparatus of claim 7 , wherein the regular polygon part is biased into the matched concavity and configured to be retractable from the matched concavity to rotate the regular polygon part and the eccentric shaft part to adjust the height of the insulation crimper.
