[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0026] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use, or the positions or positional relationships commonly understood by those skilled in the art, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 As shown, the first aspect of the utility model discloses a base, including a base body 21, on which a fixing hole 22 for fixing a contact member is provided. A groove body 23 connected to the side wall of the base body 21 is provided on the end face of the base body 21. The groove body 23 can be provided only on one end face of the base body 21, or can be provided on both ends at the same time. In addition, in order to enhance the structural stability, at least two groove bodies 23 are provided on one end face. A boss 24 is provided on one side of the groove body 23 placed on the side wall of the base body 21.

[0029] With the above structure, the base body 21 can be cylindrical or square.

[0030] Since a groove is provided on the end face of the base body, and the side of the groove close to the outside of the base body 21 is an elastic member, during assembly, the boss 24 on the base body 21 and the elastic member formed by part of the base body are squeezed inward and closed by external force, and are smoothly installed into the shell. When installed in place, the boss on the body 21 is in a naturally open state and just fits into the first groove 12 on the inner wall of the shell, and at least two bosses can play a fixing role.

[0031] At least two grooves 23 are arranged on one end face, that is, 2, 3 or 4. For the convenience of operation, preferably 2 grooves are arranged.

[0032] With the above structure, in order to effectively insert the boss 24 into the first groove of the housing, the thickness of the boss, i.e., the length along the axial direction of the base body 21, is smaller than the depth of the groove 23, i.e., the length along the axial direction of the groove 23. At the same time, the width of the boss cannot be too wide, so that the amount of inward extrusion of the boss 24 by external force during installation can be greater than the width of the boss, i.e., the length along the radial direction of the base body 21.

[0033] In order to prevent the base body from rotating after installation, a rotation-stopping groove 25 is provided on the side wall of the base body 21. The rotation-stopping groove 25 cooperates with the clamping strip 11 on the inner wall of the shell, and the clamping strip 11 is clamped in the rotation-stopping groove 25 to achieve rotation-stopping.

[0034] When the elasticity of the base body 21 is poor and the boss cannot be effectively compressed, a second groove 26 connected to the groove body 23 is provided on the side wall of the base body 21. The second groove 26 is provided so that the groove body 23 is suspended at the bottom of one side of the side wall of the base body 21. During assembly, the boss and the suspended base body 21 can be moved inward by external force to achieve assembly.

[0035] For example, refer to Figure 1 The base body 21 is cylindrical and includes a first base segment and a second base segment coaxially arranged. The cross-sectional area of ​​the first base segment is larger than the cross-sectional area of ​​the second base segment, that is, the diameter of the first base segment is larger than the diameter of the second base segment. The groove body 23 is provided on the end surface of the first base segment. There are two groove bodies 23, and the two groove bodies 23 are symmetrically arranged on the end surface of the base body 21.

[0036] Based on the base in the first aspect, the second aspect of the utility model discloses a connecting piece. Figure 2 , 3 As shown, the connecting member comprises the base in the first aspect and a shell disposed outside the base, and the shell is provided with a first groove 12 for clamping the boss 24 .

[0037] A clamping strip 11 is provided on the inner wall of the housing and is clamped in the anti-rotation groove 25 .

[0038] By adopting the above-mentioned connector structure, the base has its own fixing structure, which reduces the investment in the connector opening clamp ring, greatly reduces the cost in terms of product parts investment, and also reduces a process of assembling the clamp ring, and significantly reduces the labor time assembly cost.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
