Description

Technical Field

[0001] This utility model relates to a riveting assembly and a connector including the riveting assembly. Background Technology

[0002] In existing technologies, connectors, especially board-end connectors, are typically fastened to the mounting panel of a customer's equipment using bolts. This necessitates that the mounting panel of the customer's equipment have threaded holes. When the mounting panel of the customer's equipment is a very thin sheet metal part, a backplate is usually added to the inside of the sheet metal part, with threaded holes formed on the backplate. Furthermore, in existing technologies, if sealing is required, the backplate also needs to include a sealing ring structure to prevent leakage. Because the backplate has a certain thickness, it provides strength support to the sheet metal part, preventing deformation under stress. However, adding a backplate increases costs.

[0003] In existing technology, there is another method for securing the connector to the mounting panel. This method involves first riveting rivet nuts onto the mounting panel, and then using bolts to secure the connector to the mounting panel. The disadvantage of this method is that it requires the use of riveting tools to first rivet the rivet nuts onto the mounting panel, resulting in too many installation steps and higher costs. Utility Model Content

[0004] The purpose of this utility model is to solve at least one aspect of the aforementioned problems and defects existing in the prior art.

[0005] According to one aspect of the present invention, a riveting assembly is provided for securing a connector housing to a vehicle body sheet metal part. The riveting assembly includes: a plurality of rivet nuts, a plurality of bolts, and a washer. Each rivet nut includes a locating end. The plurality of bolts are threadedly connected to the plurality of rivet nuts respectively. The washer has at least two locating holes. The at least two locating holes of the washer engage with the locating ends of at least two of the plurality of rivet nuts respectively, such that at least two rivet nuts cannot rotate relative to the washer. The washer is adapted to be pre-installed on the connector housing by the at least two rivet nuts, such that the washer pre-installed on the connector housing does not rotate relative to the connector housing, thereby ensuring that the rivet nuts do not rotate relative to the connector housing when riveting them by rotating the bolts.

[0006] According to an exemplary embodiment of the present invention, the inner contour of the positioning hole of the pad is non-circular, and the outer contour of the positioning end of the rivet nut is non-circular and matches the inner contour of the positioning hole of the pad, so that the rivet nut cannot rotate relative to the pad.

[0018] According to an exemplary embodiment of the present invention, the positioning end of the rivet nut is used to pass through a first through hole on the connector housing, and the rivet body of the rivet nut is used to pass through a second through hole on the body sheet metal. When the rivet nut is installed on the connector housing and the body sheet metal and the bolt is tightened, the rivet body deforms under the pull of the bolt and forms a second flange abutting against the other side of the body sheet metal, so as to rivet the rivet nut to the body sheet metal and fasten the connector housing and the body sheet metal together.

[0019] According to an exemplary embodiment of the present invention, the bottom of the rivet body of the rivet nut is closed to prevent metal powder generated during the rivet process from falling out of the rivet nut; or the bottom of the rivet body of the rivet nut is open to allow the bolt to pass through the rivet body during the rivet process.

[0020] According to another aspect of the present invention, a connector is provided. The connector includes a connector housing and the aforementioned riveting assembly. The connector housing has a first through hole. The riveting assembly is detachably pre-installed on the connector housing, wherein a washer is axially held between the head of a bolt and the connector housing; or the riveting assembly is detachably pre-installed on the connector housing. A locating end of a rivet nut passes through the first through hole in the connector housing, and a rivet body of the rivet nut passes through a second through hole in a body panel. A first flange of the rivet nut and the connector housing are adapted to abut against one side of the body panel. When the rivet body of the rivet nut passes through the second through hole in the body panel and the bolt is tightened, the rivet body deforms under the pull of the bolt and forms a second flange abutting against the other side of the body panel, thereby riveting the rivet nut to the body panel and fastening the connector housing and the body panel together.

[0021] According to an exemplary embodiment of the present invention, a receiving recess communicating with a first through hole is formed on the lower side of the connector housing facing the body sheet metal part, and the first flange of the rivet nut is received and positioned in the receiving recess.

The washer 35 is adapted to be pre-installed on the connector housing 1 by at least two rivet nuts 31, such that the washer 35 pre-installed on the connector housing 1 will not rotate relative to the connector housing 1, thereby ensuring that the rivet nuts 31 will not rotate relative to the connector housing 1 when riveting by rotating the bolts 32. During riveting, the riveting tool (e.g., a torque gun) engages with the groove 32b on the head 32a of the bolt 32, driving the bolt 32 to rotate, thereby completing the riveting operation of the rivet nut 31.

[0052] like Figures 1 to 11 As shown, in an exemplary embodiment of the present invention, the inner contour of the positioning hole 305 of the pad 35 is non-circular, and the outer contour of the positioning end 311 of the rivet nut 31 is non-circular and matches the inner contour of the positioning hole 305 of the pad 35, so that the rivet nut 31 cannot rotate relative to the pad 35.

[0069] Figures 12 to 15 The second embodiment shown is similar to Figures 1 to 11 The main difference in the first embodiment shown is that the pad 35 is not used; instead, the pad 35 in the first embodiment is replaced by the engagement of the positioning end 311 of the rivet nut 31 with the first through hole 101 of the connector housing 1. Apart from this, other technical features are basically the same as in the first embodiment, and can be found by referring to [reference needed]. Figures 1 to 11 .

[0072] like Figures 12 to 15 As shown, in an exemplary embodiment of the present invention, the outer contour of the positioning end 311 and the inner contour of the first through hole 101 of the connector housing 1 are non-circular.

[0073] like Figures 12 to 15 As shown, in an exemplary embodiment of the present invention, the outer contour of the positioning end 311 and the inner contour of the first through hole 101 of the connector housing 1 are quincunx-shaped, polygonal, or elliptical. For example, in the illustrated embodiment, the outer contour of the positioning end 311 and the inner contour of the first through hole 101 of the connector housing 1 are quincunx-shaped. However, the present invention is not limited to the illustrated embodiment; for example, the outer contour of the positioning end 311 and the inner contour of the first through hole 101 of the connector housing 1 may be polygonal, elliptical, or other suitable shapes.

When the rivet nut 31 is installed on the connector housing 1 and the body sheet metal part 2 and the bolt 32 is tightened, the rivet body 310 deforms under the pull of the bolt 32 and forms a second flange 31b abutting against the other side of the body sheet metal part 2, so as to rivet the rivet nut 31 to the body sheet metal part 2 and fasten the connector housing 1 and the body sheet metal part 2 together.

[0076] like Figures 12 to 15As shown in the illustrated embodiment, the bottom of the rivet body 310 of the rivet nut 31 is closed to prevent metal powder generated during the riveting process from falling out of the rivet nut 31.
