Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, a PCB of a capsule endoscope comprises a first PCB 8, and the first PCB 8 is connected with a second PCB 9 and an antenna board 10 through a flexible FPC tape 11. The first PCB board 8 is provided with a first positioning mounting hole 8a, the second PCB board 9 is provided with a second positioning mounting hole 9a, and the antenna board 10 is provided with a third positioning mounting hole 10 a.

The PCB can be installed and fixed according to the following steps:

1) providing a C-shaped fixing frame which is of a thin-wall through structure, wherein a partition plate is arranged in the middle of the fixing frame; one surface of the clapboard is provided with a first PCB board limiting part and an antenna board limiting part; the limiting height of the antenna board limiting component is smaller than that of the first PCB board limiting component; the other surface of the clapboard is provided with a second PCB limiting part;

2) the first PCB is arranged at one end of the fixing frame and is limited by the first PCB limiting part;

3) the antenna plate is arranged at one end of the fixing frame and is limited by the limiting part of the antenna plate;

4) the second PCB is arranged at the other end of the fixing frame and is limited by the second PCB limiting part.

Specifically, as shown in fig. 2, the fixing frame includes a C-shaped bracket body 1, and a spacer 7 is disposed in the middle of the bracket body 1. One side surface of the spacer 7 is provided with two first pillars 3 opposed to each other, and the other side surface of the spacer 7 is provided with two second pillars 4 opposed to each other. The ends of the first upright post 3 and the second upright post 4 are provided with conical forced release 2.

The corresponding central angle of the spacer 7 is larger than 180 °, i.e. the spacer 7 is designed to be larger than a standard semicircle, so as to facilitate better installation of the PCB board, and a larger design space of the third upright 5.

The surface of one side of spacer 7 still is provided with third stand 5, and the height of third stand 5 is less than rather than the first stand 3 that the homonymy set up. The end of the third upright post 5 is provided with a conical post buckle 6. The center of the third upright 5 coincides with the center of the diaphragm 7.
