[0054] In an embodiment, the outer surface of each claw portion 11 comprises a first guide surface 112 tapering from the protruding portion 111 to the end of the claw portion. By guiding through the first guide surface 112, the plug-in portion can be easily inserted into the plug-in hole 210. The guide hole section 211 can be provided at the opening of the plug-in hole 210, as shown in Figure 4 and Figure 5As shown, the first guide surface 112 of the claw portion 11 moves in close contact with the inner wall surface of the guide hole section 211 of the insertion hole 210, and as the insertion portion gradually enters the insertion hole 210, the position of the first guide surface 112 in contact with the insertion hole gradually rises, so that the plurality of claw portions 11 gradually contract inward until the protruding portion 111 enters the insertion hole 210. The protruding portion 111 entering the insertion hole 210 refers to the state that the protruding portion 111 enters the enlarged portion of the insertion hole 210 beyond the limiting portion of the insertion hole 210, so that the plurality of claw portions 11 can be spread.

[0055] In an embodiment, the outer surface of each claw portion 11 is provided with an inner recess 114 extending in the circumferential direction on the side of the protruding portion 111 away from the claw portion end; the outer surface of the claw portion 11 further includes a second guide surface 113 gradually expanding from the inner recess 114 to the protruding portion 111, which can be used to guide the movement of the insertion portion when the insertion portion exits the insertion hole 210 (in a manner that allows the plurality of claw portions 11 to contract inwardly), of course, the second guide surface 113 can also not be provided if the insertion portion does not need to exit the insertion hole.

[0056] In order to allow the insertion portion to be smoothly inserted, each part of the outer surface of the claw portion 11 is smoothly transitioned, such as Figure 2 In the embodiment of

[0057] The outer surface of each claw portion 11 can further include a gradually expanding mating surface 115 formed from the inner recess 114 towards the direction away from the protruding portion 111. When the insertion portion is inserted into the insertion hole 210, the mating surface 115 can be used to cooperate with the inner surface of the guide hole section 211 at the opening of the insertion hole 210, which is beneficial to improve the stability of the connector 100 when being inserted into the insertion hole 210.

[0058] In the process of inserting the connector 100 into the insertion hole 210, the first guide surface 112 of the claw portion 11 is extruded so that the plurality of claw portions 11 contract inwardly, at this time, the inner surface of the claw portion 11 pushes the clutch member 2 to move away from the claw portion end, in order to allow the clutch member 2 to smoothly move along the inner surface of the claw portion 11, the push surface 116 is formed on the inner side surface of the claw portion 11 corresponding to the first guide surface 112, the push surface 116 gradually expands in the direction from the end of the claw portion to the protruding portion 111; the end of the clutch member 2 is provided with a stress surface 21 cooperating with the push surface 116, which is a tapered surface formed at the end of the clutch member 2 to be in close contact with the push surface 116.

Arranging the spring 3 in the first hole section 131 with a smaller hole diameter can facilitate the positioning of the spring 3.

[0060] After the plug-in part of the connector 100 is inserted into the plug-in hole 210, the clutch member 2 is moved to the first position close to the end of the claw part under the action of the spring 3, at which time the plurality of claw parts 11 cannot be retracted to exit the plug-in hole 210 under the support of the clutch member 2. In order to enable the plug-in part to exit the plug-in hole 210 to realize the disassembly of the connector 100, it is necessary to enable the plurality of claw parts 11 to be retracted inwardly, for which it is necessary to push the clutch member 2 to move away from the end of the claw part to provide a deformable inwardly retracting space for the plurality of claw parts 11.

[0061] In an embodiment, as shown in Figure 1 and Figure 2 The connector 100 further comprises a magnet 4 arranged on the clutch member 2, and the magnet 4 is on the end surface of the clutch member 2 facing the end of the claw part. Under the action of the repulsive force of the same type magnet (the same type magnet is placed at the position of the end of the plug-in part), the magnet 4 drives the clutch member 2 to move towards the spring 3, as shown in Figure 8 The clutch member 2 moves to the position away from the end of the claw part 11, so that the plurality of claw parts have a deformable space inside, so that when the second guide surface 113 of the plurality of claw parts 11 moves outwardly along the inner surface of the gradually expanding hole section 213 of the plug-in hole 210, the plurality of claw parts 11 are retracted inwardly under the extrusion force, thereby being able to exit the plug-in hole 210.
