Crimping structure and crimping method
View Patent ↗A crimping structure for a conductor utilizes a crimp barrel, wherein the crimp barrel has a plurality of crimping parts that are provided continuously along an axial direction of the conductor. The crimp barrel is formed such that the widths of the plurality of crimping parts are different from each other in the expanded state, and the plurality of crimping parts are compressed to a uniform height along the axial direction.
1. A crimping structure for a conductor comprising:
a crimp barrel formed in a U shape; and
a plurality of crimping parts integrally formed together and located on the crimp barrel continuously along an axial direction of the conductor, widths of the crimping parts being different from each other and creating a staircase shape of the barrel along the forward-rearward direction in an expanded state; and the crimping parts of differing widths being compressed to a uniform height along the axial direction.
2. A crimping structure for a conductor comprising:
a crimp barrel formed in a U shape; and
a first crimping part and a second crimping part integrally formed together and located on the crimp barrel along an axial direction of the conductor, the second crimping part being formed toward a tip end of the conductor, a width of the second crimping part being greater than a width of the first crimping part and creating a staircase shape of the barrel along the forward-rearward direction in an expanded state, and the first crimping part and the second crimping part both being compressed to a uniform height along the axial direction.
3. A crimping method for a conductor comprising:
providing a crimp barrel in a U shape and having a plurality of crimping parts integrally formed together and located on the crimp barrel continuously along an axial direction of the conductor;
forming the crimp barrel such that widths of the crimping parts are different from each other and create a staircase shape of the barrel along the forward-rearward direction in an expanded state; and
compressing the crimping parts to a uniform height along the axial direction by a paired anvil and crimper.
4. A crimping method for a conductor comprising the steps:
providing a first crimping part and a second crimping part integrally formed together and located on a crimp barrel along an axial direction of the conductor, the crimp barrel formed in a U shape;
forming the second crimping part toward a tip end of the conductor;
forming the crimp barrel such that a width of the second crimping part is greater than a width of the first crimping part creating a staircase shape of the barrel along the forward-rearward direction in an expanded state; and
compressing the first crimping part and the second crimping part to a uniform height along the axial direction by a paired anvil and crimper.
