The threaded holes of existing electronic equipment housings are prone to rusting under water spray conditions, making it difficult to insert the male threads during disassembly, and disassembling the housing is time-consuming, especially when using liquid gaskets.

Method used

A threaded portion for fastening with female and male threads is provided at the joint between the first housing and the second housing. The head of the male thread is covered by a cover. The through hole is smaller than the head of the male thread. The head of the male thread is coated with a friction-reducing material and an anti-rust coating. An opening is provided for drainage.

Benefits of technology

It avoids rusting of threaded holes, simplifies the disassembly process, reduces disassembly time, achieves lightweight and low-cost housing, and supports automated assembly and disassembly.

Abstract

In a disassembly structure in which a male screw is inserted in an electronic device housing using a seal such as a liquid gasket, there is a problem that water is splashed to cause rust in a threaded hole so that the disassembly cannot be performed. A first housing having a first flange, and a second housing having a second flange engaged with the first flange via a seal are included. A threaded portion is formed in at least a part of an engagement portion of the first flange and the second flange, the threaded portion disassembling the first housing and the second housing, and a male screw and a female screw are fastened in the threaded portion.
