Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to an easily detachable multilayer circuit board. Background Technology

[0002] Multilayer printed circuit boards (MLPCBs) are an indispensable component in modern electronic devices. They greatly improve the integration and wiring density of circuit boards by alternately stacking conductive lines and insulating layers on an insulating substrate and achieving electrical connections between layers through vias.

[0003] Existing multilayer circuit boards have the following disadvantages:

[0004] 1. Difficult to disassemble: Traditional multilayer circuit boards are often fixed by soldering, gluing and other methods. If it is necessary to repair or replace a certain layer of the circuit board, it is often necessary to destructively disassemble the entire circuit board. This not only increases the repair cost, but may also affect other normally functioning parts.

[0005] 2. Insufficient protection: Existing multilayer circuit boards may have insufficient protection, such as a lack of effective protection against pressure from external objects, which may lead to damage to the circuit boards during transportation, installation or use.

[0006] 3. Higher risk: During the disassembly process, traditional multilayer circuit boards may accidentally fall or be damaged due to the rigidity of the fixing method, which increases the risk of damage and repair costs. Utility Model Content

[0007] The purpose of this invention is to provide an easily disassembled multilayer circuit board to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an easily detachable multilayer circuit board, comprising an outer frame, a side slot on one side of the outer frame, a circuit board body movably disposed within the side slot, toothed plates fixedly disposed at the top and bottom of the circuit board body, U-shaped grooves being formed at the four corners of the front and rear end faces of the outer frame, gears being rotatably connected within the U-shaped grooves via connecting rods, a rubber plate engaging at one end of the side slot, and one end of the rubber plate being tightly fitted to the circuit board body.

[0009] Several protective strips are provided on the front and rear sides of the outer frame, and the protective strips are fixedly installed on the outer frame with screws.

[0010] Tightening blocks are fixedly installed at the front ends of two of the connecting rods.

[0011] The U-shaped groove is interconnected with the side slot.

[0012] The gear is located in the side slot, and the end face of the gear meshes with the gear plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a gear and gear plate meshing design, allowing the circuit board to be slowly and smoothly removed without being forcibly pulled out, significantly reducing the risk of damage caused by improper disassembly. This design makes circuit board replacement or maintenance more convenient and safer. Protective strips are installed on the front and rear sides of the outer frame, secured with screws, effectively preventing direct pressure or damage to the circuit board from external objects, thus improving its durability and stability.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an easily detachable multilayer circuit board, including an outer frame 1, a side slot 9 is provided on one side of the outer frame 1, a circuit board 2 is movably disposed in the side slot 9, toothed plates 10 are fixedly provided on the top and bottom of the circuit board 2, U-shaped grooves 4 are provided at the four corners of the front and rear ends of the outer frame 1, gears 6 are rotatably connected in the U-shaped grooves 4 through connecting rods 5, a rubber plate 8 is engaged at one end of the side slot 9, and one end of the rubber plate 8 is tightly attached to the circuit board 2.

[0022] Several protective strips 3 are provided on the front and rear sides of the outer frame 1. The protective strips 3 are fixedly installed on the outer frame 1 by screws. The protective strips 3 can prevent foreign objects from directly pressing on the circuit board.

[0023] Two of the connecting rods 5 have screw blocks 7 fixedly installed at their front ends. The screw blocks 7 allow the user to easily rotate the gear 6, thereby pulling out the circuit board.

[0024] The U-shaped groove 4 and the side slot 9 are interconnected.

[0025] Gear 6 is located in the side slot 9, and the end face of gear 6 meshes with toothed plate 10. The cooperation between gear 6 and toothed plate 10 allows the circuit board 2 to slowly come out without being restricted, thereby reducing the risk of accidental drop and damage.

[0026] During installation, push the circuit board body 2 into the side slot 9, while the toothed plate 10 pushes the gear 6 to rotate until the circuit board body 2 can no longer move. At this point, insert the glue plate 8.
