In this way, the insert 400 is bent and matched with the protrusion 320, so as to facilitate the installation of the plug structure 100, so that the plug structure 100 has good connectivity, stability and low cost.

[0063] It should be noted that, for the convenience of description, in the embodiment of the present application, the first direction may be the length direction of the plug structure 100, that is, Figure 2 The second direction may be the height direction of the plug structure 100, that is, Figure 2 The third direction may be the width direction of the plug structure 100, that is, Figure 2 The z direction in .

In this way, the insert 400 can slide along one end of the slide groove 340 until the insert 400 slides to the protrusion 320. It can be understood that at least part of the first bent portion 410 can be inserted into the gap 330, and the first bent portion 410 can be covered on the second bent portion 321, so that the first bent portion 410 and the second bent portion 321 are adapted to each other, and the installation of the insert 400 is completed.

In a possible implementation manner, the number of nuts 500 may be several, and the embodiment of the present application does not limit the number of nuts 500. In the embodiment of the present application, the number of nuts 500 may also be the same as the number of inserts 400, so that each nut 500 is correspondingly arranged with each insert 400.

[0068] On the basis of the above embodiment, in a possible implementation, the shapes of the nut 500 and the groove 322 can be rectangular structures. Of course, in some other embodiments, the nut 500 can also be set to other shapes, and the groove 322 of the protrusion 320 and the first bending portion 410 of the insert 400 can change with the shape of the nut 500, so that the insert 400, the protrusion 320 and the nut 500 cooperate with each other.

[0069] Continue to refer Figure 2On the basis of the above embodiment, the plug 400 may be provided with a first through hole 420 on one side facing the upper shell 200.

Alternatively, the nut 500 may be provided with a second through hole 510, and one of the inner side walls of the protrusion 320 provided with the groove 322 may be provided with a third through hole 323. It can be understood that the first through hole 420, the second through hole 510 and the third through hole 323 are arranged correspondingly, and the first through hole 420, the second through hole 510 and the third through hole 323 may all be on the same axis, so that the first fastener 520 can be sequentially penetrated through the first through hole 420, the second through hole 510 and the third through hole 323, so that the plug 400, the nut 500 and the lower shell 300 can be fixed by the first fastener 520, which is convenient for fixing the entire plug structure 100.

[0070] refer to Figure 3 On the basis of the above embodiment, hooks 220 may be respectively provided at both ends of the upper shell 200 in the first direction. The hooks 220 may be arranged toward the lower shell 300. In a possible implementation, guide grooves 350 may be respectively provided at both ends of the lower shell 300 in the first direction. In this way, when the upper shell 200 is sleeved on the lower shell 300, the hooks 220 may be engaged with the guide grooves 350, so that the upper shell 200 and the lower shell 300 are fixedly connected.

[0071] Continue to refer Figure 2 On the basis of the above embodiment, the upper housing 200 may further have mounting holes 230 at both ends in the first direction.

It is understandable that the side of the top surface 411 facing away from the upper shell 200 may directly adopt a tapping hole or a riveted nut 500 or other structural methods, so that the insert 400 and the nut 500 are directly matched and connected. Correspondingly, the side of the nut 500 facing the top surface 411 of the insert 400 may also directly adopt a tapping hole or a riveted nut 500 or other structural methods, which can also make the insert 400 and the nut 500 directly matched and connected. Among them, the dimension of one end of the insert 400 provided with the first bending portion 410 in the third direction may be less than or equal to the dimension of the other end of the insert 400 in the third direction, so as to ensure the thread strength or the space of the riveted nut 500.
