Description

Technical Field

[0001] This utility model relates to the field of circuit board holder technology, and in particular to a circuit board holder for inserting printed circuit boards. Background Technology

[0002] Printed circuit boards (PCBs) are an indispensable basic component in modern electronic devices, used to support and connect various electronic components. PCBs achieve electrical connections by printing conductive patterns on an insulating substrate, replacing the traditional point-to-point wiring method, making electronic devices more compact, reliable, and easier to manufacture.

[0003] However, in existing technologies, printed circuit boards are usually placed directly into the insertion rack. However, traditional insertion racks can only be adjusted for printed circuit boards of the same size. Therefore, different insertion racks are required for different printed circuit boards, which increases costs. Moreover, printed circuit boards are prone to shaking or tipping after being placed in the insertion rack, causing multiple printed circuit boards to stick together, which makes them difficult to remove later. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, when inserting printed circuit boards (PCBs), they are mostly placed directly into the insertion rack. However, the traditional insertion rack can only be adjusted according to PCBs of the same size. Therefore, different PCBs require different insertion racks, which increases costs. Moreover, after the PCBs are placed in the insertion rack, they are prone to shaking or tipping over, causing multiple PCBs to stick together and making them difficult to remove later.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a board holder for inserting printed circuit boards, comprising: a base plate, a side plate fixedly mounted on one side of the base plate, multiple slots formed on the base plate, and multiple vertical sliding grooves formed on the side plate, wherein the multiple sliding grooves are aligned one-to-one with the multiple slots, wherein...

[0006] A sliding rod is fixedly embedded inside the sliding groove, and a positioning plate is slidably disposed in the sliding groove. The positioning plate is also sleeved on the sliding rod, and a first spring is also sleeved on the sliding rod. The two ends of the first spring are respectively fixedly connected to the positioning plate and the bottom end of the sliding groove.

[0007] Optionally, the side plate further includes a limiting area, which is arranged in parallel with the slide groove in a one-to-one correspondence, and a plurality of limiting holes are vertically spaced in the limiting area;

[0008] A limiting plate extending into the corresponding limiting area is fixedly provided on one side of the positioning plate. A limiting pin that can be inserted into and matched with the limiting hole is movably provided on the limiting plate. The limiting pin passes through the limiting plate and is elastically connected to the limiting plate through a return spring.

[0009] Optionally, a handle is fixedly installed on the top of the positioning plate.

[0010] Optionally, an adjustment plate may be slidably disposed in the slot, and a second spring is fixedly disposed between the adjustment plate and the far end of the slot away from the side plate.

[0011] Optionally, the sidewalls of the card slots are provided with limiting grooves, and the sidewalls of the adjusting plate are also fixedly installed with limiting blocks, which extend into the limiting grooves.

[0012] Optionally, protective pads are fixedly installed on the contact surfaces of the adjusting plate and the positioning plate that are in contact with the printed circuit board.

[0013] Optionally, a baffle plate is fixedly installed on one side of the bottom of the positioning plate, and the baffle plate is disposed outside the first spring in the slide groove.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the positioning plate can be moved up and down by the handle. One side of the positioning plate is movably sleeved on the outer surface of the slide rod. When the printed circuit board is embedded in the slot, the handle is released, and the positioning plate clamps the upper end of the printed circuit board under the elastic force of the first spring, which improves the stability of the printed circuit board.

[0016] 2. After the positioning plate clamps the printed circuit board, one side is movably embedded in the limiting pin through the limiting plate. Under the elastic force of the return spring, it is embedded in the interior of one of the limiting holes. The limiting pin can limit the positioning plate and prevent the positioning plate from loosening and causing the printed circuit board to tip over. Protective pads are fixedly installed on the outer surfaces of the positioning plate and the adjusting plate. The protective pads can protect the edges of the printed circuit board and also improve the friction.

[0017] 3. In this utility model, the printed circuit board is placed inside the slot, and the second spring drives the adjusting plate to move out of the slot. The plate is adjusted according to the size of the printed circuit board to better embed the printed circuit board inside the slot. Limiting blocks are fixedly installed on both sides of the adjusting plate and are movably embedded in the limiting groove. The limiting blocks can improve the stability of the adjusting plate and better position one side of the printed circuit board. A baffle is fixedly installed on one side of the bottom of the positioning plate. The baffle can prevent the printed circuit board from contacting the first spring and better protect the printed circuit board. Attached Figure Description

Multiple limiting holes 111 are opened on the side of the side plate 101 near the slide groove 104. A handle 107 is fixedly mounted on the top of the positioning plate 106.

[0028] In this embodiment, the handle 107 can drive the positioning plate 106 to move up and down in water. One side of the positioning plate 106 is movably sleeved on the outer surface of the slide rod 105. When the printed circuit board is embedded in the slot 102, the handle 107 is released. Under the elastic force of the first spring 110, the positioning plate 106 clamps the upper end of the printed circuit board, which improves the stability of the printed circuit board.

The upper end of the printed circuit board is clamped by the positioning plate 106, which improves the stability of the printed circuit board. After the positioning plate 106 clamps the printed circuit board, one side is movably embedded in the limiting pin 117 by the limiting plate 115. Under the elastic force of the return spring 116, it is embedded in the interior of one of the limiting holes 111. The limiting pin 117 can limit the positioning plate 106 to prevent the positioning plate 106 from loosening and causing the printed circuit board to tip over. The outer surfaces of the positioning plate 106 and the adjusting plate 108 are both fixedly installed with protective pads 112. The protective pads 112 can protect the edges of the printed circuit board and also improve the friction. A baffle plate 113 is fixedly installed on one side of the bottom of the positioning plate 106. The baffle plate 113 can prevent the printed circuit board from contacting the first spring 110 and better protect the printed circuit board.
