Embodiment 1

[0054] The first embodiment of the present invention proposes a PCB board fixing structure, such as image 3 and Figure 4 As shown, a plurality of fixed points 2 are set on the PCB 1. In this embodiment, the PCB is a 10-layer double-sided PCB, and the number and positions of the fixed points are set according to fixed needs, for example Figure 4 As shown in , one fixed point 2 is set near each of the four corners of a PCB board 1 , and the fixed point can also be set at the center of the PCB board as required. A patch nut 3 is arranged on the fixed point 2, and the bottom of the patch nut 3 contains a fixed plate.

[0055] In order to make the patch nut communicate with the PCB board as a conductor, exposed copper is arranged on the fixed point 2, and the fixed plate of the patch nut is fixedly connected with the exposed copper. Since the fixed point is arranged on one side of the PCB board, there is no need to perforate the PCB board. In order to make full use of the spac...

Embodiment 2

[0058] The second embodiment of the present invention proposes a PCB board fixing structure, such as Figure 5 As shown, a plurality of fixed points 2 are set on the PCB 1. In this embodiment, the PCB is a 10-layer double-sided PCB, and the number and positions of the fixed points are set according to fixed needs, for example Figure 4 As shown in , one fixed point 2 is set near each of the four corners of a PCB board 1 , and the fixed point can also be set at the center of the PCB board as required.

[0059] Such as Figure 5 and Figure 6 As shown, the patch nut includes a fixed plate 32 arranged at the bottom and a hollow cylinder 31 arranged above the fixed plate 32, and the inner wall of the hollow cylinder is a screw column structure. In order to make the fixation of the patch nut 3 more stable and more convenient, a pad 4 is arranged on the fixed point, and the fixed pad of the patch nut 3 is fixed on the PCB board by being fixedly connected with the pad 4 1 on.

Embodiment 3

[0063] The third embodiment of the present invention proposes a mobile terminal, including a PCB board and an outer casing. The PCB board is provided with a fixed point, and the fixed point is fixed with a patch nut through a pad, and the fixing method can be Using SMT process. When the PCB board and the outer casing are fixed, the screw posts are fixed with the patch nuts fixed on the PCB board, thereby fixing the PCB board and the outer casing. The screw post is made of conductive material.

[0064] The mobile terminal realized above does not use the way of punching holes on the PCB board anymore, so one side of the PCB board is used to fix the patch nut, and the other side can be used for wiring and setting other components, increasing the PCB board effective use of space. The technological process of fixing the patch nut on the PCB is also simpler than perforating the PCB, so the production efficiency is also improved.

[0065] The serial numbers of the above embodiment...

Abstract

The invention discloses a PCB fixing structure and a mobile terminal. A PCB is provided with multiple fixed points, surface mount device type nuts are fixed on the fixed points, and the bottoms of the surface mount device type nuts comprise fixed disks. According to the PCB fixing structure and the mobile terminal, the surface mount device type nuts are arranged, other layers, not provided with the surface mount device type nuts, of the PCB can be utilized for arranging circuits or fixed components, and the effective space of the PCB is increased in a disguised mode; in addition, the process of arranging the surface mount device type nuts is easy, and improvement of production efficiency is promoted.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a PCB board fixing structure and a mobile terminal. Background technique [0002] The PCB board needs to be fixedly connected with the product shell and other components. Generally, there are many screw holes on the PCB board to get through the PCB board, and then the screw posts are fixed through the screw holes on the PCB board and the outer shell. The screw posts have a certain conduction effect. [0003] However, the perforation design of the PCB requires more process steps, and the screw holes on the PCB occupy a large area of ​​the PCB board, which is not conducive to the effective utilization of the PCB board. Contents of the invention [0004] The main purpose of the present invention is to propose a PCB board fixing structure and a mobile terminal, aiming to solve the problem of wasting a large amount of area on the PCB board by making holes on the PCB bo...
