Description

Technical Field

[0001] This application belongs to the field of circuit board equipment technology, specifically a multilayer double-sided circuit board that is easy to install. Background Technology

[0002] Multilayer printed circuit boards are circuit boards with multiple wiring layers, with a dielectric layer between each two layers. Double-sided multilayer printed circuit boards are integrated circuit boards composed of multiple double-sided circuit boards that are laminated together. They can meet the needs of a large number of interconnections in circuit board design. Common double-sided multilayer printed circuit boards are tightly laminated and fixed.

[0003] Referring to CN218941419U, a double-sided multilayer printed circuit board belongs to the field of circuit boards. It includes a first double-sided board, a second double-sided board, and a third double-sided board. Each of the second and third double-sided boards has an external mating hole at both ends. Each of the first double-sided board has two pairs of rectangular substrates at both ends. Several heat dissipation uprights are provided on the upper surface of the rectangular substrates, and a heat dissipation copper plate is provided on the top of the heat dissipation uprights. Each of the second and third double-sided boards has two pairs of heat dissipation side plates at both ends. By setting rectangular substrates at both ends of the first circuit board and then installing heat dissipation uprights and heat dissipation copper plates, and by setting corresponding heat dissipation side plates and heat dissipation horizontal plates at both ends of the second and third double-sided boards, the first double-sided board in the inner layer and the double-sided board on the outer layer can be effectively dissipated. At the same time, a fan can be selectively installed on the upper part of the outer horizontal plate to make the double-sided multilayer printed circuit board have better heat dissipation performance and meet a wider range of application needs.

[0004] However, the following problems still exist: the existing circuit boards are soldered or glued during fixing, which makes them difficult to disassemble after fixing and time-consuming and laborious to install, making it inconvenient to disassemble and install, and affecting subsequent maintenance. Utility Model Content

[0005] The purpose of this application is to provide a multi-layer double-sided circuit board that is easy to install, in order to solve the problem that the circuit board is soldered or glued during fixing, which makes it difficult to disassemble after fixing and time-consuming and laborious during installation, thus affecting subsequent maintenance.

[0006] The technical solution adopted in this application is as follows: A multi-layer double-sided circuit board that is easy to install includes a mounting plate and a placement plate. A limiting groove is formed on the upper surface of the mounting plate. A circuit board is provided on the inner wall of the limiting groove. A fixing plate is fixedly connected to the side of the circuit board. A grooved plate is fixedly connected to the upper surface of the mounting plate. A rotating rod is rotatably connected to the inner wall of the grooved plate. A pressure plate is fixedly sleeved on the surface of the rotating rod. An insert plate is fixedly connected to the back of the pressure plate. A slot is formed on one side of the insert plate. An inner groove is formed on the upper surface of the placement plate. A movable plate is slidably connected to the inner wall of the inner groove. A locking block is fixedly connected to the upper surface of the movable plate, and the locking block is adapted to the inner wall of the slot.

[0007] By adopting the above technical solution, the circuit board is first placed in the limiting groove. Then, the pressure plate is rotated sequentially by the locking groove. The rotation of the pressure plate causes the insertion plate to move down until it moves into the inner groove. At this time, the insertion plate squeezes the locking block, and the locking block moves towards the fixed plate. The spring is stretched and the pressure plate is pressed. The locking block continues to move until the insertion plate can no longer squeeze the locking block. At this time, the spring returns to its original position and pulls the baffle to move. The baffle drives the moving plate to move back to its original position. At this time, the locking block moves into the locking groove and fixes the insertion plate, thus making the device easy to install circuit boards.

[0008] In a preferred embodiment, the inner wall of the inner groove is provided with a sliding groove, and a connecting plate is slidably connected to the inner wall of the sliding groove. The side of the connecting plate away from the inner wall of the inner groove is slidably connected to the side of the moving plate.

[0009] By adopting the above technical solution and setting a connecting plate, the sliding plate can slide inside the placement plate when the moving plate is pushed through the slide groove.

[0010] In a preferred embodiment, a baffle is fixedly connected to the upper surface of the movable plate, and a spring is fixedly connected to the back of the baffle. The end of the spring away from the baffle is fixedly connected to the inner wall of the inner groove.

[0011] By adopting the above technical solution and setting a spring, the baffle can be moved after being reset, and the movement of the baffle will drive the moving plate to move.

[0012] In a preferred embodiment, the number of fixing plates is four, and the four fixing plates are arranged in a rectangular array on both sides of the circuit board.

[0013] By adopting the above technical solution and setting four fixing plates, the circuit board can be strengthened by working with four pressure plates.

[0014] In a preferred embodiment, the upper surface of the pressure plate is fixedly connected with a snap groove.

[0015] By adopting the above technical solution and setting a locking groove, it is easy for users to lock the pressure plate and rotate it.

[0016] In a preferred embodiment, the upper surface of the card block is tilted at a certain angle and is adapted to the insert plate.

[0017] By adopting the above technical solution, and by setting the upper surface of the card block to be tilted at a certain angle, it is easier to push the card block when the insert plate rotates and squeezes it.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0019] 1. In this application, the circuit board is first placed in the limiting groove. Then, the pressure plate is rotated by the locking groove. The rotation of the pressure plate causes the insertion plate to move down. The insertion plate moves down until it moves into the inner groove. At this time, the insertion plate squeezes the locking block. The locking block moves towards the fixing plate. The spring is stretched. The pressure plate is pressed down. The locking block continues to move until the insertion plate can no longer squeeze the locking block. At this time, the spring returns to its original position and pulls the baffle to move. The baffle drives the moving plate to move back to its original position. At this time, the locking block moves into the locking groove and fixes the insertion plate, so that the device has the effect of facilitating the installation of the circuit board.
