Problems solved by technology

[0002] At present, people's requirements for the appearance of the machine are getting higher and higher, and the thickness of the machine is getting thinner and thinner. The position structure of ordinary screws (also known as threaded fasteners) has an impact on the current machine thickness requirements. The position structure of ordinary screws , screws lock the middle shell, PCBA, and face shell together, such as figure 1 ; The current appearance thickness requirements, the impact of screws on the thickness of the machine, such as figure 2 ;Through the comparison of the two pictures, because the screw size occupies a certain size space, when the machine has requirements on the thickness size, the screw interferes with the shell, which affects the appearance requirements of the machine; therefore, it is difficult for the ordinary screw structure to meet the thickness requirements. The appearance and size requirements of the machine

Abstract

The invention provides a threaded fastener installing structure. The threaded fastener installing structure comprises a face shell, a circuit board and a middle shell, wherein the circuit board is arranged on the face shell, the middle shell is arranged on the circuit board, the middle shell is provided with a concave sunken table, the circuit board is provided with a receding through hole used for avoiding the concave sunken table which penetrates through the receding through hole to be arranged on the face shell, the concave sunken table is provided with a threaded fastener which is used for connecting the middle shell with the face shell, and a nut of the threaded fastener is located in the concave sunken table and is lower than that top face of the middle shell. The threaded fastener installing structure has the beneficial effects that the thickness space of the circuit board can be reasonably utilized, the concave sunken table provided with the threaded fastener is embedded into the receding through hole of the circuit board, the installing thickness of the threaded fastener is further reduced, and the small-scale design is promoted.

Description

technical field [0001] The invention relates to fasteners, in particular to a mounting structure for threaded fasteners. Background technique [0002] At present, people's requirements for the appearance of the machine are getting higher and higher, and the thickness of the machine is getting thinner and thinner. The position structure of ordinary screws (also known as threaded fasteners) has an impact on the current machine thickness requirements. The position structure of ordinary screws , screws lock the middle shell, PCBA, and face shell together, such as figure 1 ; The current appearance thickness requirements, the impact of screws on the thickness of the machine, such as figure 2 ;Through the comparison of the two pictures, because the screw size occupies a certain size space, when the machine has requirements on the thickness size, the screw interferes with the shell, which affects the appearance requirements of the machine; therefore, it is difficult for the ordina...
