[0002] Circuit board is the connecting bridge between electronic components, and is also the basis for realizing complex circuit functions. With the continuous development of electronic technology, circuit board technology is also constantly progressing. From the initial single-sided copper-clad plate, double-sided copper-clad plate, to the later multilayer board, high-frequency board, impedance board, etc., the types and performance of circuit boards have been greatly improved.

[0003] Through the search, the utility model of patent announcement number CN216391517U discloses a spliced general circuit board, which comprises a circuit board main body, a back-shaped frame is fixedly connected to the surface of the circuit board main body, four corners of the bottom of the back-shaped frame are fixedly connected with supporting legs, the front side and the rear side of the top and the right side of the bottom of the back-shaped frame are fixedly connected with connecting plates, the front side and the rear side of the left side of the top and the bottom of the back-shaped frame are fixedly connected with positioning sleeves, and trapezoidal grooves are formed in the front side and the rear side of the right side of the back-shaped frame.

[0004] Although the above-mentioned device can achieve splicing effect, it needs more accessories, and is applied to circuit boards with limited thickness, which will lead to difficult production, high production cost, and the use of more magnetic blocks in the above-mentioned device may affect the normal operation of the circuit board. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a spliced general circuit board to solve the problems in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a spliced general circuit board, comprising a circuit board one and a circuit board two, a same splicing assembly is installed between the circuit board one and the circuit board two, the splicing assembly comprises four clamping grooves formed on both sides of the outer wall of the bottom of the circuit board one and the circuit board two, one clamping strip is slidably inserted into each of the two adjacent clamping grooves, a same splicing plate is fixedly connected to the bottom outer wall of the two clamping strips, the clamping strip can be inserted into the clamping groove, and a vertical plate is fixedly connected to the outer wall of each end of the splicing plate.

[0007] As a further preferred embodiment of the present technical solution, a through groove is formed in the interior of each of the two vertical plates, and a pin plate is slidably inserted into each of the two through grooves, the pin plate is in interference fit with the circuit board one and the circuit board two, the pin plate insertion part is made of elastic plastic, and an arc edge is formed on one corner of the bottom of the pin plate.

[0008] This design allows for quick assembly of two circuit boards with a simple structure, low production cost, and ease of mass production without affecting their normal use. A slot at the bottom of each circuit board is fitted over two locking strips, causing them to fit together and creating a mutual restraint effect, preventing them from flipping or slipping out of control. This initial connection is then achieved. Next, a pin is passed through the through-hole in the vertical plate and moves to the top of the circuit boards. Due to the interference fit between the pin and the circuit boards, and the curved edges, the pin can move freely. The pin is then deformed by the pressure of the circuit boards, and the reaction force tightly presses the two circuit boards together, further improving their stability.

[0009] As a further preferred embodiment of this technical solution, an extension plate is provided on the outer wall of one end of both circuit board one and circuit board two, and a fixing component is installed on the top of each of the two extension plates.

[0010] As a further preferred embodiment of this technical solution, the fixing component includes two fixing sleeves fixedly connected to both sides of the top outer wall of the extension plate. Each of the two fixing sleeves has a pressing sleeve placed on its top, and the fixing sleeves and pressing sleeves are symmetrically arranged. The two fixing sleeves correspond to the positions of two solder pads on the top of the circuit board, and the same movable frame is fixedly connected to the top outer wall of the two pressing sleeves.

[0011] As a further preferred embodiment of this technical solution, a limiting groove with an I-shape is provided in the middle of the top outer wall of the extension plate, the movable frame is slidably inserted into the limiting groove, and a lead screw is threadedly connected inside the movable frame, with one end of the lead screw rotatably connected to the top outer wall of the extension plate through a bearing.

[0012] The wire is passed through the gap between the fixing sleeve and the compression sleeve. Then, the screw is rotated by the knob. The moving frame, which is restricted by the limiting groove, cannot rotate. Therefore, the screw can drive the moving frame and the two compression sleeves at its bottom to move downward, and the wire will be firmly fixed. This ensures that when the wire is pulled, the external force will not be applied to the welding position, thus avoiding the problem of desoldering.

[0013] As a further preferred embodiment of this technical solution, both of the card strips are made of rubber sleeves.

[0014] As a further preferred embodiment of this technical solution, multiple rubber strips are adhered to the inner circumferential walls of both fixing sleeves and both extrusion sleeves.

[0015] This utility model provides a modular universal circuit board, which has the following advantages:

[0016] (1) This utility model, by setting up splicing components, enables two circuit boards to be quickly spliced ​​together, while having a relatively simple structure, low production cost, and is easy to mass-produce without affecting the normal use of the circuit boards. A slot at the bottom of circuit board one and circuit board two is respectively fitted onto the outside of the two clips. At this time, circuit board one and circuit board two will also fit together, thus achieving a mutual restraint effect, preventing them from flipping and breaking free of the restriction at will, thereby achieving a preliminary connection. Then, the pin plate is passed through the through hole of the vertical plate, and then the pin plate will move to the top of circuit board one and circuit board two. Due to the interference fit between the pin plate and circuit board one and circuit board two, the pin plate can move normally under the cooperation of the arc edge. Then the pin plate will be squeezed by the circuit board and deformed. Its reaction force can make the two circuit boards be tightly pressed together, which is conducive to further improving the stability of the two.

[0017] (2) By setting a fixing component, the wire passes through the gap between the fixing sleeve and the compression sleeve. Then, the screw is rotated by the knob. The moving frame, which is restricted by the limiting groove, cannot rotate. Therefore, the screw can drive the moving frame and the two compression sleeves at its bottom to move downward, and the wire will be firmly fixed. This ensures that when the wire is pulled, the external force will not be applied to the welding position, thus avoiding the problem of desoldering. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 4 As shown in this embodiment, a splicing universal circuit board includes a circuit board 1 and a circuit board 2. The same splicing component 4 is installed between the circuit board 1 and the circuit board 2. The splicing component 4 includes four slots 401 opened on both sides of the bottom outer wall of the circuit board 1 and the circuit board 2. A card strip 403 is slidably inserted into each two adjacent slots 401. The same splicing plate 402 is fixedly connected to the bottom outer wall of the two card strips 403. The card strips 403 can be inserted into the slots 401. A vertical plate 404 is fixedly connected to the outer walls of both ends of the splicing plate 402.

[0025] Each of the two vertical plates 404 has a through slot, and a pin plate 405 is slidably inserted into each of the two through slots. The pin plate 405 has an interference fit with the circuit board 1 and the circuit board 2. The insertion part of the pin plate 405 is made of elastic plastic. A curved edge 406 is provided at a corner at the bottom of the pin plate 405. Since the pin plate 405 has an interference fit with the circuit board 1 and the circuit board 2, the pin plate 405 will be slightly lower than the circuit board. With the cooperation of the curved edge 406, the pin plate 405 can move smoothly without obstruction.

[0026] A slot 401 at the bottom of circuit board 1 and circuit board 2 is respectively fitted onto the outside of two clips 403. At this time, circuit board 1 and circuit board 2 will also fit together, thus achieving a mutual restraint effect and preventing them from flipping or breaking free of the restraint, thereby achieving a preliminary connection. Next, the pin plate 405 is passed through the through hole of the vertical plate 404. Then, the pin plate 405 will move to the top of circuit board 1 and circuit board 2. Due to the interference fit between the pin plate 405 and circuit board 1 and circuit board 2, and with the cooperation of the arc edge 406, the pin plate 405 can move normally. Then, the pin plate 405 will be squeezed and deformed by the circuit board. Its reaction force can make the two circuit boards tightly pressed together, which helps to further improve their stability.

[0027] like Figure 1 and Figure 4 As shown, an extension plate 3 is provided on the outer wall of one end of both circuit board 1 and circuit board 2, and a fixing component 5 is installed on the top of both extension plates 3.

[0028] The fixing component 5 includes two fixing sleeves 501 fixedly connected to both sides of the top outer wall of the extension plate 3. Each fixing sleeve 501 has a pressing sleeve 502 placed on its top, and the fixing sleeves 501 and pressing sleeves 502 are symmetrically arranged. The two fixing sleeves 501 correspond to the positions of two solder pads on the top of the circuit board 1, and the same movable frame 504 is fixedly connected to the top outer wall of the two pressing sleeves 502.

[0029] An I-shaped limiting groove 503 is provided in the middle of the top outer wall of the extension plate 3. The movable frame 504 is slidably inserted into the limiting groove 503. A lead screw 505 is threadedly connected inside the movable frame 504. One end of the lead screw 505 is rotatably connected to the top outer wall of the extension plate 3 through a bearing. The thread helix angle of the lead screw 505 is less than the equivalent friction angle, so that the position of the movable frame 504 connected to it will not change arbitrarily.

[0030] The wires are soldered to the pads on the top of circuit boards 1 and 2. Then, the wires are passed through the gap between the fixing sleeve 501 and the compression sleeve 502. The screw 505 is rotated by the knob. The moving frame 504, which is restricted by the limiting groove 503, cannot rotate. Therefore, the screw 505 can drive the moving frame 504 and the two compression sleeves 502 at its bottom to move downward, and the wires will be firmly fixed. This ensures that when the wires are pulled, the external force will not be applied to the soldering position, thus avoiding the problem of desoldering.

[0031] like Figure 2 As shown, both clips 403 are made of rubber sleeves 407, which can increase the friction between the clips 403 and the slots 401, thus improving the fixing effect.

[0032] like Figure 4 As shown, multiple rubber strips 506 are bonded to the inner circumference of the two fixing sleeves 501 and the two extrusion sleeves 502. Under the action of the multiple rubber strips 506, the tensile strength of the conductor can be improved.

[0033] This utility model provides a modular universal circuit board, the specific working principle of which is as follows:

[0034] When the device is in operation, after the splicing plate 402 is placed, the slots 401 at the bottom of circuit board 1 and circuit board 2 are respectively fitted onto the outside of the two retaining strips 403. At this time, circuit board 1 and circuit board 2 will also be in contact with each other, thus achieving a mutual restraint effect and preventing them from flipping or falling out of the restraint, thereby achieving a preliminary connection. Next, the pin plate 405 is passed through the through hole of the vertical plate 404. Then, the pin plate 405 will move to the top of circuit board 1 and circuit board 2. Due to the interference fit between the pin plate 405 and circuit board 1 and circuit board 2, and with the cooperation of the arc edge 406, the pin plate 405 can move normally. The wire will be deformed by the pressure of the circuit board, and the reaction force will make the two circuit boards tightly pressed together, which will help to further improve their stability. Then, the wire is soldered to the pads on the top of the circuit board 1 and the circuit board 2. Then, the wire is passed through the gap between the fixing sleeve 501 and the pressing sleeve 502. Then, the knob drives the screw 505 to rotate. The moving frame 504, which is restricted by the limiting groove 503, cannot rotate. Therefore, the screw 505 can drive the moving frame 504 and the two pressing sleeves 502 at its bottom to move downward, and the wire will be firmly fixed. This ensures that when the wire is pulled, the external force will not be applied to the soldering position, thus avoiding the problem of desoldering.
