[0027] The plug connector 1 has a first insulating body 11 and a first terminal 12 arranged on the first insulating body 11, and the first terminal 12 and the first insulating body 11 are preferably connected together by injection molding. The first terminal 12 has a first wiring portion 121 and a cylindrical contact portion 122 that is away from the first wiring portion 121 and is bent and changed relative to the first wiring portion 121; the first insulating body 11 is provided with a first plug post 111 and an anti-electric shock post 112 along the direction in which the cylindrical contact portion 122 is bent and extended. The first plug post 111 wraps around the outer periphery of the cylindrical contact portion 122, has insulation protection and increases the plug-in structure of the cylindrical contact portion 122. The anti-electric shock post 112 passes through the cylindrical contact portion 122, and the outer ends of the first plug post 111 and the anti-electric shock post 112 are both higher than the cylindrical contact portion 122, so that in actual application, it can effectively prevent the user's fingers from touching the cylindrical contact portion, play a good anti-electric shock effect, and is safe to use. In this embodiment, the anti-electric shock column 112 and the first plug column 111 are both formed by injection molding following the first insulating body 11, and the inner end of the cylindrical contact portion 122 is provided with a corresponding glue hole to facilitate injection molding of the anti-electric shock column 112. The first plug column 111, the anti-electric shock column 112 and the cylindrical contact portion 122 are preferably coaxially arranged, with a compact structure and good structural properties. An outer ring plug-in groove 113 is provided on the outer periphery of the first plug column 111, and a radial through hole 1131 is provided on the inner peripheral wall of the outer ring plug-in groove 113, and the radial through hole 1131 is connected to the preset tangent hole 114 on the first insulating body 11. A button 13 is implanted in the tangent hole 114, and the button 13 is supported by a support system that guides the movement of the button. A hanging portion 131 is provided on the button 13, and the hanging portion 131 follows the movement of the button 13 to be hung or unlocked.

[0028] The socket connector 2 has a second insulating body 21 and a second terminal 22 arranged on the second insulating body 21. The second insulating body 21 has a protruding second plug post 211, and a hanging platform 2111 is provided on the outer periphery of the protruding end of the second plug post 211, and an inner ring plug groove 2112 is hollowed out inside the second plug post 211. The second terminal 22 has a second wiring portion 221 and a cylindrical plug pin 222 away from the second wiring portion 221. The second wiring portion 221 is flat and connected to the cable by screw locking; the cylindrical plug pin 222 protrudes into the inner ring plug groove 2112 of the second plug post 211 to form an inner column shape. In this embodiment, it is preferred that the cylindrical plug pin 222 and the second plug post 211 are coaxially arranged, and an insulating cap is appropriately added to the top of the cylindrical plug pin 222 to improve electrical safety.

[0029] When the plug connector 1 and the socket connector 2 are matched and connected, the cylindrical pin 222 is inserted into the cylindrical contact part 122 and forms electrical conduction to realize the transmission of electric energy and signals; at the same time, the second plug post 211 corresponds to the outer ring plug groove 113 and uses the hanging platform 2111 to engage with the hanging part 131 of the button 13 to establish an anti-detachment connection. The first plug post 111 is correspondingly inserted into the inner ring plug groove 2112, and the anti-electric shock column 112 is correspondingly inserted into the inside of the cylindrical pin 222, realizing a multi-layer plug-in combination connection, and the connection structure is stable and reliable.

When the second plug column 211 is inserted into the corresponding outer ring plug groove 113, the hanging platform 2111 pushes the hanging portion 131 to be inserted into place. Under the action of the compression spring 14, the hanging portion 131 automatically rebounds and engages with the hanging platform 2111, establishing an anti-detachment connection between the plug connector 1 and the socket connector 2. When assembling the button of the utility model, the compression spring 14 is first installed in the preset accommodation cavity on the first insulating body 11, and then the button is installed. At this time, the hanging arm 133 carries the hanging part 131 and is inserted into the corresponding tangent hole 114, and the positioning arm 134 is correspondingly inserted into the positioning groove 115 on the first insulating body 11. After being inserted into place, the hook 1341 uses elasticity to self-adaptively snap into the hanging groove 1151 to form a limited snap connection, so that the button 13 is not separated from the first insulating body 11. At the same time, the compression spring 14 supports the top plate-shaped pressing part 132 from the inside to the outside, so that the button has a self-locking function. The structure is simple, easy to make and assemble, and also has detachability.
