When the first connector 20 is rotated to the use state, the second boss 228 is disengaged from the first boss 14, so that the first section 201 can be deformed to abut the first wall 110.

Further, the protruding heights of both sides of the first boss 14 toward the middle portion sequentially increase, and both sides of the first boss 41 are formed with first inclined surfaces 410, respectively. The protruding heights of both sides of the second boss 228 toward the middle portion sequentially increase, so that second inclined surfaces 2280 are formed at both sides of the second boss 228, respectively. When the second boss 228 rotates relative to the first boss 14, the second inclined surface 2280 is in contact transition with the first inclined surface 410, so that the first boss 14 and the second boss 228 can be cut in or pushed out from clearance fit to interference fit, and the wear resistance and the service life of the product are improved. The height of the first protrusion 14 is a distance from an end of the first protrusion 14 away from the first wall 110 to the first wall 110, and the height of the second protrusion 228 is a distance from an end of the second protrusion 228 away from the first abutting surface 204 to the first abutting surface 204.

Referring to fig. 20, further, the first boss 14 is spaced apart from the first hole 12 along the second direction Y, and an offset distance d is set between the center of the first boss 14 and the axis of the first hole 12. The center of the first projection 14 is spaced from the third wall 114 by a distance greater than the axial center of the first hole 12 from the third wall 114 in the second direction Y. When the first connector 20 is accommodated in the first recess 11, the second boss 228 is disposed on a side of the first boss 14 facing the third wall 114, and the first boss 14 can limit the second boss 228 to limit the rotation of the first connector 20 in the non-use state.

In some embodiments, the second wall 112 of the first housing 10 is further provided with a third protrusion (not shown), and the second abutting surface 206 of the first connecting member 20 is further provided with a fourth protrusion (not shown), where the position of the fourth protrusion corresponds to the position of the third protrusion. The structure of the third boss is the same as that of the first boss 14, and the structure of the fourth boss is the same as that of the second boss 228, which are not described herein again.

Referring to fig. 16, in some embodiments, the first housing 10 is further provided with a second concave portion 16, and the second concave portion 16 extends from the third wall 114 of the first concave portion 11 along the second direction Y. The position of the second recess 16 corresponds to the position of the second section 202, and the second recess 16 is used as a space-avoiding structure for facilitating the first connector 20 to be pulled up.

Referring to fig. 18, in some embodiments, the first connecting member 20 is further provided with an extending block 24, the extending block 24 is provided on a side of the fifth portion 202b of the second structural member 22 facing the second surface, and the extending block 24 extends from the fifth portion 202b toward the first housing 10. When the first connecting member 20 is disposed in the first recess 11, the extension block 24 is disposed on a side of the second section 202 facing away from the third wall 114, and the extension block 24 is used to facilitate pulling the first connecting member 20.

Referring to fig. 21, in the present embodiment, the first structural member 21 and the second structural member 22 of the first connecting member 20 are made of different materials, and optionally, the structural strength of the first structural member 21 is greater than that of the first connecting member 20. For example, the first structural member 21 may be made of metal such as stainless steel, aluminum alloy, or copper alloy, and the second structural member 22 may be made of plastic such as polyethylene, polypropylene, polyester, or polyurethane. The first structural member 21 is formed into a U-shaped metal insert by press forming, and the second structural member 22 is coated outside the first structural member 21 by injection molding. In the embodiment, the integral injection molding scheme of the stainless steel insert is adopted, so that the strength and the impact resistance of the integral part can be enhanced. In other embodiments, the second structural member 22 is fixed to the first structural member 21 by a mounting method, such as a snap-fit method.

Further, the first structural member 21 is provided with a plurality of fixing holes 214, and the plurality of fixing holes 214 penetrate the first structural member 21. The plurality of fixing holes 214 may be uniformly distributed in the first structural member 21, and the plurality of fixing holes 214 are used for connecting with the second structural member 22. When the second structural member 22 is injection molded, a part of the injection molding material enters the plurality of fixing holes 214 to increase the adhesion between the second structural member 22 and the first structural member 21, so as to improve the strength of the first connecting member 20.

Further, at least one positioning notch 216 is formed on the first structural member 21, and the at least one positioning notch 216 is used for positioning with the second structural member 22. When the second structural member 22 is subjected to injection molding, the first structural member 21 is disposed in the injection mold, and the at least one positioning notch 216 is aligned with the positioning structure of the injection mold, so as to ensure that the position between the second structural member 22 and the first structural member 21 after injection molding is accurate.

Compared with the prior art, in the embodiment, the first portion 201a of the first structural member 21 is located between the second connecting member 30 and the second structural member 22, the second structural member 22 is not directly connected to the second connecting member 30, and when the first connecting member 20 rotates around the second connecting member 30 relative to the first housing 10, the first structural member 21 made of metal directly contacts the second connecting member 30 made of metal, so as to improve the wear resistance and the service life of the first connecting member 20.
