Description

Technical Field

[0001] This utility model relates to the field of modular circuit board technology, specifically a modular circuit board. Background Technology

[0002] Circuit boards are also known as ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed circuit boards (copper etching technology), etc. Circuit boards make circuits miniaturized and more intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can be called printed circuit boards or printed circuit boards. However, existing modular circuit boards are mostly fixed with screws when installed, which is very cumbersome to disassemble and assemble, and inconvenient for maintenance and replacement of circuit boards. Utility Model Content

[0003] The purpose of this invention is to provide a modular circuit board to solve the problems mentioned in the background art.

[0004] By adopting the above technical solution, the circuit board can be quickly disassembled and assembled, which facilitates the maintenance and replacement of the circuit board.

[0005] Compared with the prior art, the beneficial effects of this utility model are: this combined circuit board,

[0006] The circuit board body is pushed in through the openings on both sides of the connecting groove. During the pushing process, the left and right edges of the circuit board body first contact the pushing side clamps. At this time, the side clamps are compressed and contract inward, applying pressure to the elastic column and the second spring. At the same time, the second spring and the elastic column are elastic. After being squeezed, they will absorb the pressure and release it again, so that the pushing side clamps fit tightly against both sides of the circuit board body, fixing the circuit board body from the side. When the circuit board body is continuously pushed inward, it will squeeze the flipped extension part of the shrinkage groove. At this time, after the shrinkage groove flips, it will drive the extension part with the second insulating pad to clamp the circuit board body, ensuring the stability of the circuit board body. At the same time, the top sides of the connecting assembly are also equipped with front clamping components. After the first rotating plate rotates and is parallel to the circuit board body, the telescopic rod is pressed to retract the first clamping plate, thereby clamping and fixing it to the top side of the circuit board body, further improving the fixing effect of the circuit board body. Screws can also be installed through the threaded mounting holes for further reinforcement. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-4 The present invention provides a technical solution: a combined circuit board, including a circuit board body 1, adjacent circuit board bodies 1 are connected by a connecting component 2, and front clamping components 204 are provided on the left and right sides of the end of the connecting component 2. The connecting component 2 is used to connect two adjacent circuit board bodies 1, and the front clamping components 204 are used to reinforce the stability of the two adjacent circuit board bodies 1 from the end.

[0014] The connecting assembly 2 includes a connecting groove 201. The connecting groove 201 has several contraction grooves 207 inside. Two central shafts 206 are rotatably connected to the inner side of each contraction groove 207. A second clamping plate 209 is rotatably connected to the outer side of each central shaft 206. A first spring 205 is provided on the outer side of each second clamping plate 209. A connecting shaft 210 is provided inside the openings on both the left and right sides of the connecting groove 201. A side block 213 is rotatably connected to the other end of each connecting shaft 210. An elastic post 212 is provided on the outer side of each side block 213. A second spring 211 is provided on the outer side of each elastic post 212.

[0015] First, the circuit board body 1 is pushed into the connecting groove 201 through the openings on both sides. During the pushing process, the left and right edges of the circuit board body 1 first contact the pushing side latches 213. At this time, the side latches 213 are compressed inward and apply pressure to the elastic post 212 and the second spring 211. At the same time, the second spring 211 and the elastic post 212 are elastic. After being squeezed, they will absorb the pressure and release it again. Thus, the pushing side latches 213 are tightly attached to both sides of the circuit board body 1, fixing the circuit board body 1 from the side. When the circuit board body 1 is continuously pushed inward, it will squeeze the shrinkage groove 207. When the retractable extension part of the circuit board 207 flips over, it drives the extension part with the second insulating pad 208 to clamp the circuit board body 1, ensuring the stability of the circuit board body 1. At the same time, front clamping components 204 are also set on the top two sides of the connecting component 2. After the first rotating plate 2041 rotates and is parallel to the circuit board body 1, the telescopic rod 2042 is pressed to retract the first clamping plate 2043, thereby clamping and fixing it on the top side of the circuit board body 1, further improving the fixing effect of the circuit board body 1. Screws can also be installed through the threaded mounting hole 203 for further reinforcement.

[0016] The front clamping assembly 204 includes a side extension plate 2044. There are two side extension plates 2044, located on the left and right sides of the connecting groove 201 respectively, and they are symmetrically distributed. The inner side of each side extension plate 2044 is rotatably connected to a first rotating plate 2041. The upper and lower ends of the outer side of the first rotating plate 2041 are provided with telescopic rods 2042.

[0017] By rotating the first rotating plate 2041 to make it parallel to the circuit board body 1, and then pressing the telescopic rod 2042, the first clamping plate 2043 is retracted, thereby clamping and fixing it to the top side of the circuit board body 1, further improving the fixing effect of the circuit board body 1. At the same time, the first insulating pad 2045 is provided on the inner side of the first clamping plate 2043 to prevent the first clamping plate 2043 from directly contacting the circuit board body 1 and causing damage.

[0018] The telescopic rod 2042 has a first clamping plate 2043 fixedly connected to the outer side of the rod body, and a first insulating pad 2045 fixedly connected to the inner side of the first clamping plate 2043. The first insulating pad 2045 can prevent the first clamping plate 2043 from directly contacting the circuit board body 1 and causing damage to it, and is used to protect the circuit board body 1.

[0019] Several ventilation holes 202 are provided in the middle of the connecting groove 201. Each ventilation hole 202 is arranged in a cross shape, and the inner opening is located at the edge of the circuit board body 1. The ventilation holes 202 are used to ensure the heat dissipation effect inside the connecting groove 201. The part of the front clamping assembly 204 that contacts the connecting groove 201 is provided with threaded mounting holes 203. The threaded mounting holes 203 are used to install screws to further fix the circuit board body 1 and the connecting groove 201.

[0020] The inner side of the extension of the second clamping plate 209 is fixedly connected with a second insulating pad 208. The second insulating pad 208 and the first insulating pad 2045 are both provided to prevent the first clamping plate 2043 and the second clamping plate 209 from directly contacting the circuit board body 1.
