Description

Technical Field

[0001] The utility model relates to the field of ceramic circuit boards, in particular to a ceramic circuit board bracket structure. Background Art

[0002] Ceramic circuit boards are an indispensable part of LED lighting. Ceramic circuit boards can provide more heat conduction routes for LEDs, allowing LEDs to fully dissipate heat, and at the same time prevent the lamp beads from short-circuiting due to foreign objects, thereby ensuring the life and safety of the lamp. Wireless communication Ceramic circuit boards are also widely used in wireless communication equipment. Through the use of ceramic circuit boards, radio frequency signal processing and transmission can be better realized, thereby improving the reception and transmission effects of the equipment.

[0003] Brackets are needed in the production and processing of ceramic circuit boards. Brackets are used to hold and fix circuit boards. Most existing ceramic circuit board brackets fix the circuit boards by fastening bolts, which is relatively troublesome. The Chinese utility model patent with application number 202220083008.9 discloses a bracket structure for ceramic circuit boards. A clamping groove is provided on the fixing groove on the bracket body, and the bracket plate is clamped by the clamping groove. The clamping holes on the arc plate are clamped with the limiting structure. This design is used to fix the position of the bracket plate, thereby facilitating the fixation of the position of the ceramic circuit board. However, the device fixes the circuit board on both sides of the circuit board, and it is necessary to pull up the clamping frame first, and then put the circuit board into the clamping frame for fixing. The operation is relatively cumbersome. Ceramic circuit boards are mostly rectangular structures. At present, there is no bracket that can clamp and fix the circuit board from both ends of the diagonal and is easy to operate. Summary of the invention
