Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments.

As shown in fig. 1 to 4, the present invention provides a PCB assembly, which is installed and fixed on a heat dissipation plate 10, wherein the heat dissipation plate 10 is provided with heat dissipation holes 11 regularly distributed. The PCB assembly includes a PCB body and a fixing assembly for fixedly mounting the PCB body on the heat dissipation plate 10.

The PCB is characterized in that a plurality of mounting holes are formed in the PCB body, the fixing assembly is matched with the mounting holes and the heat dissipation holes, and when the type of the PCB body changes, only the fixing assembly needs to be replaced by another heat dissipation hole 11 for fixing.

The fixing component comprises a base 21 and a locking piece 22 matched with the base 21 for installation, the base 21 comprises a supporting portion 211 and a limiting portion 214 connected to one end of the supporting portion 211, the circumferential radius of the limiting portion 214 is smaller than that of the supporting portion 211, so that a step is formed between the supporting portion 211 and the limiting portion 214 for supporting the PCB 30, and a space is formed between the PCB 30 and the heat dissipation plate 10. The end face of the base 21, which faces away from the locking member 22, is provided with an accommodating groove 212, the middle part of the bottom of the accommodating groove 212 further penetrates inwards to form a positioning hole 216 penetrating through the limiting part 214, the outer side of the limiting part 214 is provided with a limiting block 215, the limiting block 215 is distributed around the circumference of the limiting part 214, the outer diameter of the limiting block 215 is gradually increased from two sides to the middle part, so that the two sides of the limiting block 215 form guide slopes, the hole wall of the positioning hole 216 is provided with internal threads, the front end of the limiting part 214 is further provided with a plurality of inward extending movable grooves 216, the movable grooves 216 divide the limiting part 214 into a plurality of pieces, and the flaky limiting part 214 has elasticity. The whole locking part 22 is arranged in a T shape, and the rod of the locking part 22 is provided with an external thread.
