Almost every electronic device, from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, must use circuit boards to make electrical connections between various components.

[0003] When using traditional circuit boards, modules with different functions are usually installed on different circuit boards, and then multiple circuit boards are welded together to form a complete board. The more modules installed on the circuit board, the larger the size of the entire circuit board. When a module in a larger circuit board is damaged, the entire circuit board needs to be removed for repair, which will lead to problems such as inconvenience in disassembly and repair.

[0004] Therefore, it is particularly important to improve the existing spliced ​​circuit boards and design a new spliced ​​circuit board to solve the above technical defects and improve the practicality of the overall spliced ​​circuit board. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0026] A spliced ​​circuit board includes a circuit board 1, a central processing unit 2 is arranged on the top of the circuit board 1, two groups of through slots 3 are opened on the left side of the circuit board 1, and a clamping assembly 4 is installed inside the through slots 3;

[0027] The clamping assembly 4 is used for quickly splicing multiple groups of circuit boards 1 .

[0028] For further information, see Figure 3 , Figure 4 and Figure 5In this embodiment, the clamping assembly 4 includes a turning handle 401, a main rod 402, a control block 403, a clamping plate 404 and a spring 405. The turning handle 401 is installed at the top of the through slot 3, the main rod 402 is installed at the bottom of the turning handle 401, the control block 403 is installed at the bottom of the main rod 402, the clamping plates 404 are symmetrically installed on the left and right sides of the control block 403 and are located inside the through slot 3, and the spring 405 is installed between the clamping plates 404. When the circuit board 1 is used for a long time and suffers from wear and tear, when the damaged circuit board 1 needs to be disassembled and repaired separately, by rotating the turning handle 401, the main rod 402 drives the control block 403 to rotate with the turning handle 401, thereby driving the clamping plates 404 to approach each other, realizing the contraction of the spring 405, and at the same time, the internal space of the through slot 3 is increased, and the circuit boards 1 are separated by moving another group of circuit boards 1.

[0029] Among them, see Figure 3 , Figure 4 and Figure 5 In this embodiment, a sliding rod 406 is installed inside the main rod 402, and a connecting shaft 407 is installed at the bottom of the control block 403. The control block 403 is connected to the through slot 3 through the connecting shaft 407. By rotating the handle 401, the handle 401 drives the control block 403 to rotate, and at the same time rotates through the connecting shaft 407. By pulling the sliding rod 406 out of the inside of the main rod 402, the handle 401 is raised, so that it is more labor-saving to rotate the handle 401.

[0030] Furthermore, please see Figure 3 , Figure 4 and Figure 5 In this embodiment, a track is installed on the side where the splints 404 are close to each other, and a first connecting rod 408 and a second connecting rod 409 are installed on the top and bottom of the control block 403 respectively. The ends of the first connecting rod 408 and the second connecting rod 409 away from the control block 403 are connected to the track. Through the movement of the control block 403, the first connecting rod 408 and the second connecting rod 409 are swung, thereby completing the movement of the splints 404 away from and close to each other, thereby enhancing their linkage.

[0031] Furthermore, please see Figure 3 , Figure 4 and Figure 5 In this embodiment, a protrusion 410 is installed on the side away from the clamping plate 404, and a clamping column 5 is installed on the side away from the through groove 3 of the circuit board 1. A circular hole is opened in the interior of the clamping column 5 at a position corresponding to the protrusion 410. The clamping plates 404 are moved away from each other, so that the clamping column 5 is separated from the interior of the protrusion 410, and the clamping column 5 is released from the fixation of the protrusion 410. The circuit board 1 is moved again to separate the clamping column 5 from the interior of the through groove 3, so that the circuit boards 1 can be quickly disassembled.

[0032] For further information, see Figure 1 and Figure 2 In this embodiment, a connecting hook 6 is installed on the left side of the circuit board 1 and on the front and rear sides of the through slot 3. The connecting hook 6 is a plastic connecting hook. A connecting hole is opened at a position corresponding to the connecting hook 6 on the right side of the circuit board 1. When the circuit boards 1 need to be spliced, the connecting hook 6 is inserted into the connecting hole. The connecting hook 6 is made of plastic material. The practicability is greatly enhanced through the unique elasticity and insulation of the plastic material.

[0033] For further information, see Figure 1 and Figure 2 In this embodiment, a semi-arc 101 is installed on the front side of the circuit board 1, and a round tube 102 is installed on the rear side of the circuit board 1. The semi-arc 101 and the round tube 102 are used in conjunction with each other, and a special-shaped block 7 is installed between the connecting holes. A special-shaped groove 701 is provided at a position corresponding to the special-shaped block 7 on the right side of the circuit board 1. When multiple circuit boards 1 need to be spliced, the semi-arc 101 is inserted into the outside of the round tube 102 to achieve connection between the front and rear sides of the two groups of circuit boards 1. The special-shaped block 7 is inserted into the inside of the special-shaped groove 701 to make the connection between the two groups of circuit boards 1 tighter.

[0034] For further information, see Figure 1 and Figure 2 In this embodiment, a thermally conductive insulating layer 8 and a circuit layer are respectively provided on the top of the circuit board 1. The circuit board 1, the thermally conductive insulating layer 8 and the circuit layer are integrated by welding. The thickness of the thermally conductive insulating layer 8 is 0.2-0.5 cm. The circuit layer is a copper foil circuit layer. The copper foil has a low surface oxygen property. The conductive copper foil is placed on the surface of the circuit board 1, so that it has excellent conductivity and provides an electromagnetic shielding effect.

[0035] In this embodiment, the implementation scenario is specifically as follows:

[0036] When the circuit board 1 is worn out after long-term use, it is necessary to disassemble and repair the damaged circuit board 1 separately, by rotating the turning handle 401, the main rod 402 drives the control block 403 to rotate with the turning handle 401, and at the same time, the connecting shaft 407 rotates, and the sliding rod 406 is used to pull the inside of the main rod 402 out to raise the turning handle 401, so that it is more labor-saving to rotate the turning handle 401, and the first connecting rod 408 and the second connecting rod 409 are swung, so as to complete the separation and approach of the clamping plates 404. The movement of the spring 405 causes the spring 405 to contract, and at the same time, the internal space of the through slot 3 is increased, so that the clamping column 5 is separated from the inside of the protruding column 410, and the clamping column 5 is released from the protruding column 410. The circuit board 1 is moved again to separate the clamping column 5 from the inside of the through slot 3, and the circuit boards 1 are quickly disassembled. The front and rear sides of the two groups of circuit boards 1 are connected by inserting the semi-arc 101 into the outside of the round tube 102, and the connection between the two groups of circuit boards 1 is tighter by inserting the special-shaped block 7 into the inside of the special-shaped slot 701.
