Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle manufacturing and maintenance tools, and more specifically, to a portable copper wire crimper for new energy vehicles. Background Technology

[0002] In new energy vehicles, the high-power electrical transmission places extremely high demands on the reliability and stability of copper wire connections. Currently, copper wire crimping in practice mostly relies on hand tools, such as common pliers. Operators use pliers to simply squeeze the copper wires to achieve crimping, relying on their experience.

[0003] The copper wires used in existing new energy vehicles come in a wide variety of specifications. When faced with copper wires of different specifications, the size and shape of the pliers are relatively fixed, and they can only be used to fit a limited number of copper wire specifications. Once a copper wire that does not match the pliers is encountered, it is impossible to apply uniform and sufficient pressure, resulting in poor pressing effect. Workers need to frequently change tools according to the specifications of the copper wire. Each time the specifications of the copper wire are changed, it is necessary to search for a suitable pliers among many tools, which consumes a lot of time.

[0004] Therefore, we have made improvements to this and proposed a portable copper wire presser for new energy vehicles. Utility Model Content
