Description

Technical Field

[0001] Cross - reference to related applications This application claims the benefit of Chinese Patent Application No. CN202411898765.1, filed with the China National Intellectual Property Administration on December 20, 2024, the entire disclosure of which is incorporated herein by reference.

[0002] The present invention relates to a pull - type rivet assembly, a product comprising the pull - type rivet assembly, a product assembly comprising the product, and a method of wearing the product.

Background Art

[0003] In the prior art, connectors, especially board - end connectors, are usually bolted when assembled to the mounting panel of a customer's device. This requires the mounting panel of the customer's device to have threaded holes. When the mounting panel of the customer's device is a very thin sheet - metal part, due to the thinness of the sheet - metal part, it is usually necessary to add a back - plate inside the sheet - metal part and form threaded holes in the back - plate. In addition, in the prior art, when a seal is required, a seal - ring structure also needs to be added to the back - plate to prevent water leakage. Due to the thickness of the back - plate, the back - plate can provide a certain strength support for the thin sheet - metal part and prevent deformation due to stress. However, the addition of the back - plate increases the cost.

[0004] In the prior art, there is also a solution for fastening a connector to a mounting panel. This solution involves first riveting a rivet nut to the mounting panel. Next, bolts are used to fix the connector to the mounting panel. The disadvantage of this solution is that a rivet tool is required to first rivet the rivet nut to the mounting panel, resulting in too many mounting steps and high costs.
