Description

Technical Field

[0001] This utility model relates to the field of PCB circuit board technology, and specifically to a PCB circuit board with a flexible protection structure. Background Technology

[0002] Circuit boards are also known as ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, PCBs, aluminum substrate boards, high-frequency boards, thick copper boards, impedance boards, ultra-thin circuit boards, and printed circuit boards. Circuit boards miniaturize and visualize circuits, playing a crucial role in the mass production of fixed circuits and optimizing the layout of electrical appliances. A circuit board, also called a printed circuit board, is a highly reliable and flexible printed circuit board made with polyimide or polyester film as the substrate. It features high wiring density, light weight, and thinness, and is mainly used in many products such as mobile phones, laptops, PDAs, digital cameras, and LCMs.

[0003] Currently, existing PCB circuit boards do not have flexible protective structures at the top and bottom during installation, and their heat dissipation is poor, resulting in a reduced lifespan. Therefore, there is an urgent need for a PCB circuit board with a flexible protective structure to overcome these defects. Utility Model Content

[0004] The purpose of this invention is to provide a PCB circuit board with a flexible protection structure, which has the advantages of flexible protection and long service life, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB circuit board with a flexible protection structure, comprising a bottom flexible component, a top flexible component, a PCB circuit board body, and a positioning and mounting protection component. The PCB circuit board body is disposed within the inner cavity of the bottom flexible component. The positioning and mounting protection components are disposed on both sides of the top of the PCB circuit board body. The top of the positioning and mounting protection component is provided with a top flexible component. The bottom flexible component includes a mounting shell, a first threaded seat, a first spring, a heat dissipation copper plate, a rubber ring, a positioning post, and a slot. The top flexible component includes a top cover, a second threaded seat, a top plate, and a foam column. The positioning and mounting protection component includes a positioning rod, a through slot, a second spring, a third spring, a locking rod, a pressure plate, and a handle.

[0006] Furthermore, the first threaded seats are all fixedly installed around the perimeter of the mounting housing, and the positioning posts are all slidably mounted around the perimeter inside the PCB circuit board body, with the bottom of the positioning posts fixedly connected to the bottom of the inner cavity of the mounting housing.

[0007] Furthermore, a rubber ring is provided on the surface of the positioning post and at the bottom of the PCB circuit board body, a slot is provided inside the positioning post, and a second threaded seat is fixedly installed around the top cover.

[0008] Furthermore, a foam column is fixedly installed at the bottom of the top cover, a top plate is fixedly installed at the bottom of the foam column, and through grooves are opened on both sides inside the positioning rod.

[0009] Furthermore, a locking rod is slidably connected inside the through groove, a handle is fixedly installed on the top of the locking rod, and a second spring is fixedly installed in the inner cavity of the through groove on the side relatively close to the locking rod.

[0010] Furthermore, a third spring is fixedly installed on both sides of the bottom of the positioning rod, and a pressure plate is fixedly installed on the bottom of the third spring. The side of the locking rod that is relatively far away from each other passes through the locking groove into the interior of the positioning column.

[0011] Furthermore, a heat dissipation copper plate is provided at the bottom of the PCB circuit board body, and four first springs are fixedly installed at the bottom of the heat dissipation copper plate. The bottom of the first springs is fixedly connected to the bottom of the inner cavity of the mounting shell.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention provides flexible support and protection for the bottom of the PCB circuit board body by setting a bottom flexible component, while also conducting heat to cool the bottom of the PCB circuit board body. A top flexible component provides flexible protection for the top of the PCB circuit board body. A positioning and installation protection component fixes the PCB circuit board body and provides flexible protection for both sides of the top of the PCB circuit board body. During installation, the PCB circuit board body is first placed on top of the rubber ring using positioning posts, and the rubber ring provides cushioning and damping. Then, the positioning rod is placed in the designated position, and the pressure plate and the third spring work together to reduce the pressure on both sides of the top of the PCB circuit board body. After vibration protection, release the handle. Under the action of the second spring, the locking rod passes through the slot into the interior of the positioning post, thereby fixing the positioning rod and indirectly fixing the PCB circuit board body. After fixing, move the top cover downward and fix the second threaded seat and the first threaded seat with bolts. After fixing, under the action of the foam column, the top plate is tightly attached to the top of the PCB circuit board body, thus providing flexible protection for the top of the PCB circuit board body. It has the advantages of flexible protection and long service life, solving the problem that the current PCB circuit boards do not have flexible protection structures at the top and bottom during installation, and the heat dissipation effect is poor, which leads to a reduced service life.
