Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1 and 2, a PCB assembly structure for a mobile hard disk includes a cap 10 and a PCB 20. The plug 10 includes an abutting plate 12, and a clamping plate 14 disposed on the abutting plate 12. The abutting plate 12 is provided with a limiting member 122, and the limiting member 122 is provided with a limiting groove 124. The clamping plate 14 is provided with a clamping groove 142, a buckle 30 is arranged in the clamping groove 142, and the PCB 20 is connected with the buckle 30 in a clamping manner after being inserted into the limiting groove 124.

The PCB 20 is directly inserted into the limiting groove 124 of the limiting member 122, the limiting groove 124 limits the PCB 20 in the vertical direction, and the PCB 20 is connected to the clip 30 after being inserted into the limiting groove 124. The clip 30 not only limits the PCB 20 in the left-right direction, but also clips the PCB 20 to prevent it from loosening. Through locating part 122 and buckle 30 installation PCB board 20, reduce the manual work, practice thrift consumptive material reduce cost, improve production efficiency, and the installation is more stable.

Referring to fig. 3, in the present embodiment, the clip 30 is integrally formed with the clip plate 14. Specifically, the clip 30 includes an elastic portion 32 disposed in the slot 142, and a clip portion 34 connected to the elastic portion 32 and exposed from the slot 142. The clamping portion 34 directly contacts the PCB 20 and is clamped with the PCB 20 by the elastic force provided by the elastic portion 32, so that the mounting stability of the PCB 20 is ensured.

Further, the clamping portion 34 is provided with an inclined surface 342 in a direction close to the PCB 20. By providing the inclined surface 342, the clamping process of the clamping portion 34 and the PCB board 20 becomes smooth. Further, the engaging portion 34 has a curved surface 344 connected to the inclined surface 342. By providing the curved surface 344, the clamping process of the clamping portion 34 and the PCB 20 is further smoothed, and the curved surface can also reduce the friction between the clamping portion 34 and the PCB 20.

The side of the PCB 20 is provided with a clamping groove 22, and the buckle 30 is arranged in the clamping groove 22. After joint portion 34 and PCB board 20 joint, buckle 30 is located in joint groove 22, and buckle 30's thickness is less than the degree of depth in joint groove 22 for buckle 30 butt joint groove 22, thereby prevent that PCB board 20 is not hard up, improve PCB board 20's installation stability.

Further, the plug 10 is provided with a butting block 126, and the butting block 126 is used for being butted with the PCB 20 after being inserted into the limiting groove 124 with the PCB 20. By providing the abutment block 126, further movement of the PCB board 20 after it is snapped into the clip 30 is avoided.

The clamping connection plates 14 are provided with two groups, and the two groups of clamping connection plates 14 are respectively arranged on the left side and the right side of the abutting connection plate 12. The two sets of clamping plates 14 can ensure better stability of the PCB 20.

The abutting plate 12 is further provided with a plurality of clamping blocks 126. After the PCB 20 is mounted on the plug 10, the plug 10 is used to be mounted on the casing of the mobile hard disk, and the plug 10 is tightly clamped with the casing by adding the dry clamping block 126. Furthermore, a locking hole 144 is formed on the clamping plate 14. After the plug 10 is tightly clamped with the shell, a screw passes through the locking hole 144 for locking, and the installation and fixation of the plug 10 are completed.

The embodiment also provides a mobile hard disk, which comprises a shell and the PCB assembly structure, wherein the PCB is arranged in the shell, and the plug is fixed on the shell.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
