Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a crimping die for an automobile wiring harness shielding ring. Background Art

[0002] Automotive wire harness shield ring crimping dies are specialized tools used to tightly crimp shield rings (such as braided copper wire or metal foil) onto wiring harness connections, ensuring good electrical contact and electromagnetic interference (EMI) shielding. Made of high-strength steel, the dies consist of an upper die, a lower die, and a positioning mechanism. The crimping force is provided by a hydraulic or pneumatic system.

[0003] In the existing technology, traditional shielding ring crimping methods often have problems such as complex operation, low efficiency, and unstable crimping quality. Announcement No.: CN220710817U discloses a crimping die for automotive wiring harness shielding rings. The die rotates a rotating block driven by a rotating shaft, which in turn drives a tensioning plate. The tensioning plate continuously rotates under the action of centrifugal force and tends to extend outward, thereby contacting and rubbing against the inner surface of the shielding ring, thereby tensioning the shielding ring. The extrusion effect of the shielding ring and the pressurized protrusion when in contact creates multiple concave points on the shielding ring, enhancing the crimping effect.

[0004] However, when using this device, it is not convenient to position the wire harness. The mold that is not convenient to position requires the operator to spend more time and energy to manually adjust the position of the wire harness during the crimping process, which increases the complexity and difficulty of the operation.

[0005] Based on this, a crimping die for an automobile wiring harness shielding ring is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
