Description

Technical Field

[0001] The utility model relates to a fastening assembly, a product comprising the fastening assembly, a product assembly comprising the product, an installation method of the product and a connector. Background Art

[0002] In the prior art, when connectors, especially board-end connectors, are assembled to the mounting panel of the customer's equipment, they are usually fastened by bolts. This requires that the mounting panel of the customer's equipment has threaded holes. When the mounting panel of the customer's equipment is a sheet metal with a very thin thickness, since the sheet metal is very thin, it is usually necessary to add a back plate on the inner side of the sheet metal and form threaded holes on the back plate. In addition, in the prior art, if sealing is required, the back plate also needs to add a sealing ring structure to prevent water leakage. Since the back plate has a certain thickness, it can provide a certain strength support to the sheet metal to prevent the sheet metal from being deformed by force. However, adding a back plate will increase costs.

[0003] In the prior art, there is another solution for fastening the connector to the mounting panel. In this solution, a rivet nut is first riveted on the mounting panel. Then the connector is fastened to the mounting panel with bolts. The disadvantage of this solution is that a special rivet tool is required to first rivet the rivet nut to the mounting panel, resulting in too many installation steps and high costs.
