Abstract
An anti-loosening connection structure of an electric coupler is characterized by comprising a plug shell body (1), a snap spring (2), a check ring (3), a corrugated spring (4), an anti-loosening disc (5), a coupling nut (6) and a socket shell body (7). The anti-loosening connection structure overcomes the shortcomings that former similar structures are complex in form, poor in part machining manufacturability, heavy in structural weight and non-uniform in anti-loosening effect. The anti-loosening connection structure enables electric coupler products in threaded connection to have the advantages of being reliable in locking, simple and convenient to operate, light in weight, small in boundary dimension and good in manufacturability.
