一种三通推拉自锁同轴电连接器
By employing a push-pull self-locking structure with snap-fit teeth and slots, along with a movable sleeve design, and combining a tee adapter with a modular plug/socket combination, the problems of insufficient quick assembly/disassembly and self-locking in existing electrical connectors are solved. This achieves a connector design that is flexible to replace and highly reliable, and improves signal stability and vibration resistance.

AI Technical Summary
Existing electrical connectors have shortcomings in terms of quick assembly/disassembly and self-locking. Threaded connections are cumbersome to operate, the plug-in/plug-out structure is prone to loosening under vibration, and the plug and socket of the tee connector are fixed and cannot be replaced.
It adopts a push-pull self-locking structure with snap-fit teeth and snap-fit grooves, combined with a movable sleeve design, to achieve one-handed operation for locking and unlocking; the combination of a three-way adapter and a modular plug/socket allows for flexible replacement; threaded reinforcement and insulation protection improve vibration resistance and signal stability.
It achieves a fast and reliable self-locking function, supports flexible replacement of plugs and sockets, improves connection reliability and signal stability in vibration environments, and reduces operational complexity and production costs.

Abstract
Claims
1. A tri-axial push-pull self-locking coaxial electrical connector, characterized in that, include: A socket assembly includes a socket housing and a socket member. One end of the socket housing is formed with a first cylindrical part. The socket member is vertically fixed to the bottom axis of the first cylindrical part. A snap-fit groove is provided circumferentially on the inner wall surface of the first cylindrical part. A plug assembly, comprising a plug housing and a pin, wherein a second cylindrical portion is provided at one end of the plug housing corresponding to the first cylindrical portion, the pin is vertically fixed at the bottom axis of the second cylindrical portion, and a plurality of locking teeth are provided on the surface of the second cylindrical portion; The adapter has at least three adapter ports for connecting the end of the socket assembly or plug assembly away from the first cylindrical part or the second cylindrical part. The second cylindrical part of any plug assembly can be inserted into the first cylindrical part of another socket assembly to connect the socket and the pin, and the locking teeth are located in the locking groove.
2. The tee push-pull self-latching coaxial electrical connector of claim 1, wherein, The outer peripheral wall of the second cylindrical part is formed with a plurality of snap-fit strips defined by openings or slits at intervals along the circumference. Each snap-fit strip is integrally formed with the second cylindrical part and is connected to the second cylindrical part through one side to form a fixed end. The remaining edges are spaced apart from the second cylindrical part to serve as free ends, so that each snap-fit strip can be elastically deformed in the radial direction. The snap-fit teeth are provided at the free ends of each snap-fit strip and protrude outward in the radial direction.
3. The tee push-pull self-latching coaxial electrical connector of Claim 2, wherein, A movable sleeve is fitted on the surface of the second cylindrical part, and a through hole is opened on the surface of the movable sleeve corresponding to the snap-fit tooth. The snap-fit tooth extends out of the through hole. The movable sleeve can move along the surface of the second cylindrical part so that the edge of the through hole presses the snap-fit tooth, causing the snap-fit tooth to retract into the through hole.
4. The tee push-pull self-latching coaxial electrical connector of Claim 1, wherein, Both the socket housing and the plug housing have a nut at the end away from the first cylindrical part or the second cylindrical part, and the adapter interface has a threaded part corresponding to the nut.
5. The tee push-pull self-latching coaxial electrical connector of Claim 1, wherein, Insulating elements are fitted onto parts of the surfaces of the pin and the socket.
