Screw Specifications

Screw head table

In the existing industrial technology field, screws are mostly used for the connection between components. For many electronic products, because the products are more and more thin and light, the connection between the shell and the shell is often affected by the thickness of the shell. , usually need to use screw column structure for connection. Take the existing outdoor three-proof mobile phone as an example: the screw column structure includes a shell, a shell and a screw, the shell is provided with a plurality of screw columns, and the nuts in the screw columns are injected through the in-mold injection process. Directly integrated with the housing. Due to the special use environment and use requirements of outdoor three-proof mobile phones, they need to have good high-strength anti-drop performance, while the three-proof mobile phones in the prior art are subjected to high-strength drop tests due to the fundamental stress concentration of the screw column. During the process, problems such as cracking of the screw column or breaking from the root occur.

At present, there are many kinds of smart terminals on the market. Due to the reduction of the overall volume of the smart terminal and the more compact internal parts, the nuts are generally made of injection-molded nuts. The traditional injection-molded nuts are directly fixed on the equipment. During the process, it is easy to loosen and fall off, which greatly reduces the service life of the injection nut and brings inconvenience to the use of the mobile terminal.
