Description

Technical Field

[0001] This utility model belongs to the technical field of heat dissipation fixtures for circuit board debugging, and mainly relates to a heat dissipation fixture suitable for debugging standard and non-standard circuit boards. Background Technology

[0002] A circuit board (PCB) is a modular hardware component consisting of a printed circuit board and its mounted electronic components. It is widely used in computers, communications, industrial control, and consumer electronics. Depending on its function, a PCB may contain components such as a processor, memory, interface circuits, power management, and signal conditioning to perform a specific task.

[0003] Because power devices on circuit boards generate a lot of heat during use, heat dissipation is required to ensure that the components operate within a suitable temperature range. Existing heat dissipation fixtures for circuit boards are box-type structures, which are extremely cumbersome and inconvenient to disassemble and assemble. Furthermore, for irregularly shaped circuit boards, special heat dissipation structures must be designed for them, which is costly, time-consuming, and extremely costly, but with very low testing efficiency.

[0004] Therefore, there is an urgent need for a heat dissipation fixture suitable for debugging both standard and non-standard boards, which can be used for both standard and non-standard boards and is easy to disassemble. Utility Model Content

[0005] To address the problems in the prior art, this utility model proposes a heat dissipation fixture suitable for debugging standard and non-standard circuit boards. It has a simple structure, low manufacturing cost, high heat dissipation efficiency, and is easy to disassemble for debugging. It is applicable to both standard and non-standard circuit boards.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A heat dissipation fixture suitable for debugging standard and non-standard circuit boards includes a base plate. A test support assembly and a fan assembly are mounted on the base plate. The fan assembly provides cooling air to the circuit boards. The test support assembly comprises multiple sets, each including a wing screw, a sliding rod, a double-ended hexagonal stud, and a hexagonal nut. The sliding rod is horizontally mounted on the base plate, with a groove at one end through which the wing screw passes and is fixed to the base plate. The other end of the sliding rod is provided with a double-ended hexagonal stud, which is vertically mounted, its bottom fixed to the end of the sliding rod, and its top provided with a hexagonal nut for mounting the circuit board.

[0007] Furthermore, the board is provided with multiple fixing holes for penetrating double-headed hexagonal studs.

[0008] Furthermore, the fan assembly includes a fan housing cover plate, a fan, and a fan housing. The bottom of the fan housing is fixed to the fan mounting area of ​​the base plate, the fan is fixedly installed inside the fan housing, and the fan housing cover plate is fixed to the fan housing by combination screws.

[0009] Furthermore, the bottom of the base plate is provided with multiple rubber feet.

[0010] Furthermore, the base plate is provided with a fan mounting area and a testing area. The fan mounting area is used to install fan assemblies, and the testing area is provided with a number of mounting holes for installing wing screws.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a heat dissipation fixture suitable for debugging standard and non-standard circuit boards. Compared with debugging by placing the circuit board inside the chassis, the initial debugging stage does not require the design of matching structural components and a chassis for heat dissipation, reducing costs. The circuit board can be directly placed on the fixture support, and its movement can be restricted by hexagonal studs, or it can be fixed with nuts. The circuit board is easy to disassemble and assemble during debugging. The circuit board support structure adopts a sliding linkage structure, which can adjust the position of the double-headed hexagonal studs to adapt to different mounting hole positions. It can not only meet the debugging needs of standard circuit boards, but also meet the debugging needs of irregular (non-standard) circuit boards, increasing debugging efficiency and reducing design costs. The heat dissipation fixture has a simple structure and is easy to process, which greatly reduces design and processing costs. Attached Figure Description

[0019] like Figures 1-3 As shown, a heat dissipation fixture suitable for debugging standard and non-standard circuit boards is provided, including a base plate 5. A test support component and a fan component are provided on the base plate 5. The test support component is used to install the circuit board 10 to be debugged, and the fan component is used to deliver cooling air to the circuit board 10 to be debugged to achieve heat dissipation.

[0020] Specifically, the base plate 5 has multiple rubber feet 9 at its bottom for supporting the base plate 5. The base plate 5 is divided into two areas: a fan mounting area and a testing area. The fan mounting area is used to install fan components, and the testing area has several mounting holes for installing test support components and for adjusting the installation position of the test support components according to installation needs.

[0021] The fan assembly includes a fan box cover plate 1, a fan 2, and a fan box 4. The bottom of the fan box 4 is fixed to the fan mounting area of ​​the base plate 5. The fan 2 is fixedly installed inside the fan box 4. The fan box cover plate 1 is fixed to the opening of the fan box 4 by combination screws 3 to ensure the safe use of the fan assembly.

[0022] The test support assembly consists of multiple sets, each set including a wing screw 8, a sliding connecting rod 7, a double-ended hexagonal stud 6, and a hexagonal nut 11. The sliding connecting rod 7 is horizontally mounted on the base plate 5, with a closed end groove at one end. The wing screw 8 passes through the groove and is fixed in the mounting hole of the base plate 5. The other end of the sliding connecting rod 7 is provided with a double-ended hexagonal stud 6, which is vertically mounted. Its bottom is fixed to the end of the sliding connecting rod 7, and its top is fitted with the hexagonal nut 11 to mount and fix the plate 10. Correspondingly, the plate 10 has multiple fixing holes to facilitate the top of the double-ended hexagonal stud 6 to pass through and tighten the hexagonal nut 11, thereby enabling the test support assembly to support and fix the plate 10.

[0023] The matching of the wing screw 8 and the sliding link 7 here allows for adjustments to the installation position of the wing screw 8 on the base plate 5 and the position and angle of the wing screw 8 in the groove of the sliding link 7 when the position needs to be changed. This ensures that the double-headed hexagonal stud 6 meets the installation requirements of various irregularly shaped boards, greatly improving testing efficiency.

[0024] Each set of test support components can be fixed at different positions on the base plate 5 according to installation requirements, thereby supporting the board 10 to complete the debugging.

[0025] It should be noted that the fan assembly is also equipped with a switch and a speed adjustment button to control it. Since the switch and speed adjustment button are common devices and belong to existing mature technology, their electrical connection relationship and specific circuit structure will not be described in detail here.

[0026] The working process of the heat dissipation fixture applicable to the debugging of standard and non-standard boards described in this embodiment is as follows: In use, first fix one end of the double-headed hexagonal stud 6 to the sliding connecting rod 7, and pass the other end through the fixing hole of the plate 10; place the sliding connecting rod 7 on the base plate 5, slide and rotate the connecting rod 7 on the base plate 5 to find the appropriate mounting hole position, and use the wing screw 8 to pass through the sliding groove of the sliding connecting rod 7 to fix the sliding connecting rod 7 to the base plate 5; the plate 10 is supported on the base plate 5 by the double-headed hexagonal stud 6, and the hexagonal nut 11 is tightened to the hexagonal stud 6 to fix the plate 10; during debugging, turn on the fan 2 for heat dissipation.

[0027] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
