It has the characteristics of high wiring density, light weight, thin thickness and good bending properties. The double-sided board of this circuit board has a dielectric layer in the middle and both sides are wiring layers. The multi-layer board is a multi-layer wiring layer, and there is a dielectric layer between every two layers. The dielectric layer can be made very thin. The multi-layer circuit board has at least three conductive layers, two of which are on the outer surface, and the remaining layer is synthesized in the insulating board. The electrical connection between them is usually achieved through the plated through holes on the cross section of the circuit board.

However, when one of the multi-layer circuit boards is damaged, it is difficult to repair and replace it, resulting in a waste of resources. At the same time, the existing multi-layer circuit boards have poor heat dissipation performance during use, which affects their service life.

[0004] Therefore, it is particularly important to improve the existing plug-in type multilayer circuit board, design a new plug-in type multilayer circuit board to solve the above technical defects, and improve the practicality of the overall plug-in type multilayer circuit board.

DETAILED DESCRIPTION

[0021] 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.

[0022] Example:

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

The clamping component 4 is used to fix the multilayer circuit board 3, and the disassembly component 5 is used to open and close the box door 2 and the outer frame 1.

[0025] For further information, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the clamping assembly 4 includes a screw rod 401, a movable sleeve 402, a first connecting plate 403, a fixed sleeve 404, a second connecting plate 405 and a connecting rod 406. The screw rod 401 is symmetrically installed on the left and right sides of the outer frame 1, the movable sleeve 402 is installed on the outside of the screw rod 401, the first connecting plate 403 is installed on the outside of the movable sleeve 402 and is located inside the outer frame 1, the fixed sleeve 404 is installed on the outside of the screw rod 401 and is located below the movable sleeve 402, the second connecting plate 405 is installed on the outside of the fixed sleeve 404, and the connecting rod 406 is installed between the first connecting plate 403 and the second connecting plate 405. When the multi-layer circuit board 3 needs to be replaced and repaired, the screw rod 401 is rotated so that the movable sleeve 402 rotates outside the screw rod 401, so that the connecting rod 406 is unfolded, so that the first connecting plate 403 is away from the second connecting plate 405, thereby releasing the fixation of the multi-layer circuit board 3.

[0026] Among them, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the movable sleeve 402 is threadedly connected to the outside of the screw rod 401, and fixed seats 407 are installed on the left and right sides of the first connecting plate 403 and the second connecting plate 405. Both ends of the connecting rod 406 are rotatably connected to the inside of the fixed seat 407. The connecting rod 406 is deployed more smoothly through the fixed seat 407, so that the first connecting plate 403 is more stable when performing lifting and lowering movements.

[0027] Second, see Figure 1 , Figure 2 and Figure 3 In this embodiment, a clamping plate 408 is installed on one side of the first connecting plate 403 and the second connecting plate 405, and an electrostatic pad is installed on the surface of the clamping plate 408. The clamping plate 408 makes the multi-layer circuit board 3 more stable during installation.

[0028] Furthermore, please see Figure 1 , Figure 2 and Figure 3In this embodiment, a knob 409 is installed on the top of the screw rod 401, and multiple groups of anti-slip grooves are provided on the outside of the knob 409.

The base 410 is fixedly connected to the outer frame 1 through the connecting block. The friction between the palm and the knob 409 is increased by the anti-slip grooves, so that the knob 409 can rotate the screw rod 401 more labor-saving.

[0029] For further information, see Figure 1 , Figure 2 and Figure 4 In this embodiment, the disassembly assembly 5 includes a connecting column 501, a protrusion 502, a circular groove 503, a slide groove 504, a socket 505 and a limit block 506. The connecting column 501 is installed inside the box door 2, the protrusion 502 is installed outside the connecting column 501, the circular groove 503 is opened on the front of the outer frame 1, the slide groove 504 is opened inside the circular groove 503 at a position corresponding to the protrusion 502, the socket 505 is installed on the inner side wall of the circular groove 503, and the limit block 506 is installed inside the socket 505. By inserting the connecting column 501 into the circular groove 503 and the protrusion 502 into the slide groove 504, the connection column 501 is stabilized, and the protrusion 502 is inserted into the socket 505 by rotating the connecting column 501, and the protrusion 502 is clamped by the limit block 506, so as to complete the quick installation between the box door 2 and the outer frame 1.

[0030] For further information, see Figure 1 , Figure 2 and Figure 4 In this embodiment, a pull ring 507 is installed on the side of the connecting column 501 away from the box door 2, and a spring is provided inside the limit block 506. The pull ring 507 makes the finger more flexible when using it. When the protrusion 502 is separated from the limit block 506, it is reset by the spring.

[0031] Finally, see Figure 1 and Figure 2 In the present embodiment, a card slot is provided inside the outer frame 1 and on a side away from the box door 2, a silicone pad is installed inside the card slot, and a ventilation net 6 is provided on the top of the outer frame 1. The rear end of the multi-layer circuit board 3 is connected by the card slot, and used in conjunction with the clamping plate 408, the stability of the multi-layer circuit board 3 installed inside the outer frame 1 is improved.

[0032] In this embodiment, the implementation scenario is specifically as follows: when the multi-layer circuit board 3 needs to be replaced and repaired, the screw rod 401 is rotated inside the base 410 by moving the twist knob 409, so that the movable sleeve 402 is rotated outside the screw rod 401, so that the connecting rod 406 is unfolded, so that the first connecting plate 403 is away from the second connecting plate 405, and the clamping plates 408 are away from each other, so that the contact clamping plates 408 fix the multi-layer circuit board 3, and the connecting column 501 is rotated to disengage the protrusion 502 from the limit block 506, so that the protrusion 501 is stuck in the slide groove 504, and the connecting column 501 is pulled out to disengage the connecting column 501 from the inside of the circular groove 503, thereby completing the disassembly and assembly between the box door 2 and the outer frame 1, so that the multi-layer circuit board 3 can be taken out for repair or replacement.
