Description

Technical Field

[0001] The utility model relates to the technical field of terminal lead crimping, in particular to a terminal lead crimping anti-deformation device. Background Art

[0002] Terminals are conductive parts of electrical appliances that are fixedly electrically connected to external circuits. They are commonly used electrical wiring tools. Terminals are generally composed of a crimping part and a connector part. The crimping part refers to the sleeve part that presses or tightens the lead wire, and the connector part refers to the part that is connected to the electrical component.

[0003] At present, for the crimping of terminals and leads, pliers are generally used to directly pinch the sleeve part and the lead wire. This crimping method has poor effect and cannot fix and clamp the terminal and the lead wire well, which easily causes the terminal to shake. At the same time, the sleeve part is directly pinched flat with pliers, so that the internal lead wire will also be deformed after crimping, which not only affects the work efficiency but also the quality of the terminal wire. When the terminal wire is loosely connected, it is easy to cause heat or even fire, posing a great safety hazard. Utility Model Content
