[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "top / bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention 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 invention.

[0024] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" 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 utility model can be understood according to specific circumstances.

[0025] The structural features of the utility model are now described in detail with reference to the accompanying drawings of the specification.

[0026] See also Figure 1-Figure 2 A connector rivet post includes a pressure riveting part 1 and an expansion riveting part 2. The expansion riveting part 2 is a hollow structure. The pressure riveting part 1 is provided with knurling 4 on its circumference. A connection part 3 that can be broken after rotation is provided between the pressure riveting part 1 and the expansion riveting part 2. The outer diameter of the pressure riveting part 1 is larger than the outer diameter of the connection part 3. After pressure riveting, the expansion riveting part 2 is squeezed and flattened and fixed on the two parts. When the rivet post needs to be removed, it is only necessary to use a wrench that is compatible with the knurling 4, put it on the pressure riveting part 1, and rotate it continuously in one direction. Since the connection part 3 is thin, when the rotation force is applied, the part of the connection part 3 will be twisted first, and the continuous rotation will cause the connection part 3 to break, thereby realizing the separation of the pressure riveting part 1 and the expansion riveting part 2 after pressure riveting.

[0027] The rivet post of the connector of the utility model is provided with a thinner connecting portion 3 between the pressure riveting portion 1 and the expansion riveting portion 2, and knurling 4 is provided on the circumference of the pressure riveting portion 1. After riveting, the pressure riveting portion 1 is continuously rotated so that the connecting portion 3 is "twisted off", thereby separating the pressure riveting portion 1 from the expansion riveting portion 2, so that the rivet post can be easily removed after pressure riveting without damaging the rivet hole and parts.

[0028] Example 2

[0029] Reference Figure 3 As another preferred embodiment of the utility model, the difference from embodiment 1 is that a limiting strip 5 is provided on the inner circumference of the expansion riveting part 2. By providing the limiting strip 5 in the expansion riveting part 2, when the pressure riveting part 1 is screwed, a screwdriver or other tools that can be inserted into the expansion riveting part 2 and can block the limiting strip 5 can be used to prevent the rivet column from rotating in the rivet hole after pressure riveting.

[0030] Example 3

[0031] Reference Figure 4As another preferred embodiment of the utility model, the difference from embodiment 3 is that a plurality of rivet openings 6 are provided in the circumferential direction on one side of the rivet portion 2 located at the port, and the rivet openings 6 divide the end of the rivet portion 2 into a plurality of rivet strips 7. The setting of the rivet openings 6 can make the rivet portion 2 easier to press rivet, and can reduce the impact on the internal aperture of the rivet portion 2 after press riveting, so that the tool for blocking the limit strip 5 can be more conveniently inserted into the rivet portion 2.

[0032] Example 4

[0033] Reference Figure 5 As another preferred embodiment of the utility model, the difference from embodiment 3 is that a plurality of easy-bending grooves 8 are provided on the outer circumference of the expansion riveting part 2 and corresponding to the position of the expansion riveting strip 7. By providing the easy-bending grooves 8, the expansion riveting strip 7 can be more easily bent during pressure riveting. Since the expansion riveting part 2 lacks support at the position of the easy-bending groove 8, the expansion riveting strip 7 will bend toward one side of the easy-bending groove 8 during pressure riveting, and the bent parts are unified to form a petal shape, which effectively improves the aesthetics of the parts after pressure riveting.

[0034] Example 5

[0035] Reference Figure 6 As another preferred embodiment of the utility model, the difference from the embodiment 4 is that a wedge block 9 is provided inside the expansion riveting strip 7, and the expansion riveting strip 7 can be press-riveted outward by providing the wedge block 9. By providing the expansion riveting opening 6, the easy-breaking groove 8 and the wedge block 9 on the expansion riveting part 2, the expansion riveting part 2 can be evenly expanded to the surroundings, which can reduce the pressure of press riveting on the one hand, and improve the aesthetics of the riveted position of the parts after press riveting on the other hand.

[0036] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
