Description

Technical Field

[0001] The utility model relates to the technical field of wire harness crimping, in particular to a wire harness processing error-proof crimping tool. Background Art

[0002] The ends of the wiring harness need to be equipped with terminals that can connect to the wires inside the harness to achieve connection with other electrical equipment. Typically, wiring harness terminals are made by stripping the insulation at the end of the harness, connecting the terminals to the wires inside the harness, and crimping the terminals to the harness. The parts of the wiring harness terminal to be riveted include a core wire crimping portion connected to the insulation at the end of the harness, and a conductor crimping portion crimped to the wires at the end of the harness. Therefore, during crimping, the core wire crimping portion and the conductor crimping portion of the terminal need to be crimped separately.

[0003] Traditional crimping tools are often crimped manually, requiring the worker to hold the wire harness and press down for crimping. Workers are prone to fatigue from manually holding the wire harness and terminals for a long time, which can easily lead to pinching of fingers, posing a certain risk. At the same time, manual pressure is used for crimping, resulting in unstable pressure, which can easily lead to excessive or insufficient pressure. Excessive pressure can easily damage the workpiece, while insufficient pressure can easily lead to unstable connections. Based on this, this solution provides a wire harness processing error-proof crimping tool to solve the above-mentioned problems. Utility Model Content

The top of the upper crimping block is fixedly connected to a top plate, and the left and right sides of the lower end of the top plate are fixedly connected to a telescopic rod, and the other end of the telescopic rod is fixedly connected to the upper end of the bracket.
