Referring to fig. 2, an embodiment of the present invention provides a socket, including a socket body 1 and a spring piece 2, where the socket body 1 is provided with a slot 11, and the slot 11 is used for plugging and unplugging a plug 3; referring to fig. 3 and 4, the elastic sheet 2 includes a fixing portion 21, a contact protrusion 22, a support protrusion 23 and a first bending portion 24, the fixing portion 21 is connected to the socket body 1 to fix the elastic sheet 2 to the socket body 1; the contact projection 22 projects inside the slot 11 for abutting against the plug 3 when the plug 3 is inserted into the slot 11; the supporting protrusion 23 is connected between the fixing portion 21 and the contact protrusion 22, the protrusion direction of the supporting protrusion 23 is opposite to the protrusion direction of the contact protrusion 22, that is, the contact protrusion 22 protrudes toward the inner side of the slot 11, and the supporting protrusion 23 protrudes toward the slot wall 111 of the slot 11, a gap is formed between the supporting protrusion 23 and the slot wall 111 of the slot 11 in a natural state, when the contact protrusion 22 is pressed by the plug 3, the supporting protrusion 23 abuts against the slot wall 111 of the slot 11, and the elastic sheet 2 deforms; the first bent portion 24 is connected between the fixing portion 21 and the support boss portion 23, and functions to connect the fixing portion 21 and the support boss portion 23.

When the plug 3 is inserted into the slot 11, the plug 3 generates an extrusion force (as shown in fig. 4F) on the contact protrusion 22 to press down the contact protrusion 22, in this process, the first bending portion 24 deforms to make the support protrusion 23 approach the slot wall 111 of the slot 11 until the support protrusion 23 contacts the slot wall 111 of the slot 11, at this time, as the contact protrusion 22 continues to press down, the first bending portion 24 stops deforming, the support protrusion 23 starts to deform until the plug 3 is inserted in place, and at this time, the contact protrusion 22 presses down to the maximum extrusion stroke.

Therefore, when the plug 3 is inserted into the slot 11, the plug 3 extrudes the elastic sheet 2, the contact bulge 22 serves as a pressure bearing point for bearing extrusion force of the plug 3, and the first bending part 24 and the support bulge 23 are deformation points, which is equivalent to dispersing deformation of the root of the elastic sheet (namely deformation of a joint of the elastic sheet and the socket) in the prior art to different parts of the elastic sheet 2 (namely the first bending part 24 and the support bulge 23), so that the deformation amount of a single deformation point of the plug 3 during each plugging and unplugging is reduced, stress concentration at the single deformation point is reduced, fatigue of the elastic sheet 2 is reduced, the service life of the elastic sheet 2 is prolonged, the risk of fatigue and permanent deformation of the elastic sheet 2 after the plug 3 is plugged and unplugged for many times is reduced, good contact between the socket and the plug 3 is ensured, and the electrostatic risk is reduced.

It should be noted that, in the present embodiment, the specific number of the supporting protrusions 23 is not limited, and the number of the supporting protrusions 23 may be one, or may be two or more, and it can be understood that, the greater the number of the supporting protrusions 23, the smaller the deformation amount of a single deformation point of the elastic sheet 2 is, and the smaller the stress concentration at the single deformation point is, the longer the service life of the elastic sheet 2 can be prolonged, and the contact between the plug 3 and the socket is ensured to be good.

In some embodiments, there are at least two supporting protrusions 23, a second bending portion 26 is connected between two adjacent supporting protrusions 23, and the gap between the supporting protrusions 23 and the groove wall 111 of the slot 11 gradually increases in a natural state along a direction from the fixing portion 21 to the contact protrusion 22. As shown in fig. 5, the number of the supporting protrusions 23 is two, and a second bending portion 26 is connected between the two supporting protrusions 23.

That is, the first bending portion 24, all the supporting protrusions 23 and all the second bending portions 26 in this embodiment are deformation points, when the plug 3 is inserted into the slot 11, the plug 3 generates a pressing force on the contacting protrusions 22 to press down the contacting protrusions 22, in this process, the first bending portion 24 deforms, so that the supporting protrusions 23 closest to the first bending portion 24 contact with the slot walls 111 of the slot 11, and as the contacting protrusions 22 continue to press down, each supporting protrusion 23 and each second bending portion 26 sequentially deform to make each supporting protrusion 23 sequentially contact with the slot walls 111 of the slot 11 until the plug 3 is inserted in place (i.e. the contacting protrusions 22 press down to the maximum pressing stroke).

It can be seen that this embodiment has increased the deformation point of shell fragment 2 through setting up the support bellying 23 more than two, makes the stress concentration of shell fragment 2 more dispersed, is favorable to prolonging the life of shell fragment 2, guarantees the contact goodness of plug 3 and socket. In addition, it can be understood that, in the process that the contact protrusion 22 is pressed by a force, because the fixing portion 21 is connected with the socket body 1, the support protrusion 23 close to the fixing portion 21 is firstly deformed under the limitation of the fixing portion 21, and after the support protrusion 23 close to the fixing portion 21 abuts against the groove wall 111 of the slot 11, each support protrusion 23 is sequentially deformed along the direction from the fixing portion 21 to the contact protrusion 22, therefore, in this embodiment, the gap between the support protrusion 23 and the groove wall 111 of the slot 11 is gradually increased in a natural state, which is beneficial to sequentially deforming each support protrusion 23 along the direction from the fixing portion 21 to the contact protrusion 22, so as to ensure that each deformation point has a proper deformation amount, and avoid an excessively large deformation amount of any one support protrusion 23 caused by uneven gaps between each support protrusion 23 and the groove wall 111 of the slot 11.

That is to say, the free end of shell fragment 2 can begin just with cell wall 111 butt, like this, when shell fragment 2 produced deformation, the free end of shell fragment 2 can regard as the strong point, and the pressure of deformation is undertaken to the help, has favorable to having promoted the stability that shell fragment 2 and cell wall 111 contacted. Of course, the following scheme is also possible: the free end of the elastic sheet 2 does not abut against the groove wall 111 at first, but keeps a certain gap with the groove wall 111 in a natural state, and in the process that the contact protrusion 22 is pressed down under force, the free end of the elastic sheet 2 abuts against the groove wall 111, which is equivalent to increasing the contact support point of the elastic sheet 2 and the groove wall 111, and also can improve the contact stability of the elastic sheet 2 and the groove wall 111.

It can be understood that, compared with the situation that only the free end of the elastic sheet 2 abuts against the groove wall 111, the contact area between the elastic sheet 2 and the groove wall 111 is increased by providing the third bending portion 25 in the present embodiment, so that the contact between the elastic sheet 2 and the groove wall 111 is more stable.

It should be noted that the specific orientation of the third bending portion 25 is not limited in this embodiment, and as shown in fig. 4 and 5, in some embodiments, the third bending portion 25 is formed by bending the free end of the elastic piece 2 toward the supporting protrusion 23. That is, the end of the third bent portion 25 faces the support boss 23, and the third bent portion 25 is bent toward the inside of the spring piece 2.

Of course, in other embodiments, as shown in fig. 7, the third bending portion 25 may also be formed by bending the free end of the resilient piece 2 in a direction away from the supporting protrusion 23.
