The invention discloses a bayonet connector with an elastic pin locking mechanism. The bayonet connector has a plug and socket, the plug comprises a plug shell and a connecting screw cap provided witha staple bolt; the socket comprises a socket shell and a curved groove. The tail end of the curved groove is provided with a staple bolt groove which is matched with the staple bolt to realize primary locking; the elastic pin locking mechanism is arranged on the connecting screw cap; the connecting screw cap comprises a locking pin, a guide rod and an unlocking push button; the unlocking push button is fixedly connected with the locking pin, a through hole is formed in the connecting screw cap, the guide rod is installed on the inner wall of the connecting screw cap and sleeved with an elastic piece, the locking pin is provided with a clamping groove in sliding fit with the guide rod, and the elastic piece pushes the locking pin in a free state to enable the locking pin to abut against the front end hole wall of the through hole; the socket shell is provided with a locking groove, and after the staple bolt falls into the staple bolt groove to realize primary locking, the locking pin is inserted into the locking groove under the pushing effect of the elastic piece to realize secondary locking. According to the invention, the bayonet connector cannot be unlocked under the conditionthat the locking pin is not opened, and the hidden danger of vibration unlocking failure of the connector in a high-frequency vibration environment is avoided.
Description
technical field [0001] The invention belongs to the technical field of connectors, in particular to a bayonet connector with a spring pin locking mechanism. Background technique [0002] The current bayonet connector uses the elastic force provided by the corrugated spring or rubber pad. The socket is connected, and the curved groove generally adopts a three-curved groove. When plugging in, the staple is aligned with the entrance of the head end of the three-curved groove, and then the connecting nut is rotated to tighten the staple in the staple groove at the end of the three-curved groove for locking . There are some hidden dangers in the locking of this structure: (1) In the vibration application environment, the bayonet structure composed of staples and three-curved grooves has the hidden danger of locking failure caused by the staples coming out of the staple grooves; (2) During use, when the connector is dragged or rotated, the staple may also be twisted out of the s...
