Structure for fixing nuts to surface shell and mobile terminal

Abstract

The invention provides a structure for fixing nuts to a surface shell and a mobile terminal. The structure for fixing the nuts to the surface shell comprises the nuts and the surface shell, wherein the nuts are provided with bodies and limiting parts arranged on the bodies; the bodies are provided with threaded holes; the surface shell is provided with mounting grooves for mounting the nuts; side walls of the mounting grooves are provided with limiting matching parts; the limiting parts are matched with the limiting matching parts in order to limit the movement of the nuts relative to the surface shell. According to the structure for fixing the nuts to the surface shell provided by the invention, the limiting parts on the nuts are matched with the limiting matching parts on the side walls of the mounting grooves after the nuts are mounted in the mounting grooves from open ends of the mounting grooves, so that the movement of the nuts relative to the surface shell can be limited; fixing of the nuts to the surface shell is realized; the requirement on mold accuracy is lowered; and a high molding yield is achieved. Moreover, the nuts can be fixed without any Z-direction structural component, so that the mounting accuracy of the nuts on the surface shell is increased, and the mounting strength is enhanced.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, and more specifically, to a fixing structure of a nut on a face shell and a mobile terminal including the fixing structure of the nut on the face shell. Background technique [0002] In existing mobile terminals such as mobile phones, there are generally two ways to fix the nuts on the inner shell. One method is to inject the nut into the surface shell plastic through the in-mold injection molding process. Because this kind of fixing method requires in-mold inlay injection molding, the nut needs to be placed manually, which will increase the labor cost and affect the yield rate; It cannot be moved, and the plastic hole needs to be sealed, which requires high mold precision, resulting in long molding cycle, low yield and high cost. Another way is to put the nut directly into the shell, without in-mold injection molding, relying on the Z-direction structural parts to press ins...

Another way is to put the nut directly into the shell, without in-mold injection molding, relying on the Z-direction structural parts to press inside the casing, which requires low mold precision, high yield, and simple assembly; but the nut is directly placed in the Z It needs to be connected with other parts, the installation accuracy of the nut will be reduced, and the fixing strength of the nut is insufficient
