Description

Technical Field

[0001] This utility model relates to the technical field of plug crimping, specifically to an automatic crimping device. Background Technology

[0002] A connector, also known as a plug or socket, is generally an electrical connector. It connects two active devices to transmit current or signals.

[0003] Plugs typically require cable connections. To ensure the lifespan of the plug and cable connection, reinforcing rings are usually tightened and secured. Current methods often involve manually placing the pre-assembled plug with cable onto a fixture for positioning, then manually operating a pressure rod to control the pressure block to press down, which then tightens and secures the reinforcing ring. However, this method is labor-intensive, leading to worker fatigue over long periods, decreased clamping accuracy, and defective products. It also results in low processing efficiency, hindering production. Furthermore, the dimensions of the fixture's placement groove and the pressure block's clamping groove are often fixed, unable to be automatically adjusted according to requirements. Different sizes of fixtures are needed for subsequent reinforcing ring fixation, resulting in long replacement times and reduced processing efficiency. Additionally, custom-made fixtures of various specifications are required, increasing customization costs and storage space, which cannot meet the needs of mass production of plugs with cables.
