DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following are specific embodiments of the present utility model in conjunction with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0025] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between the components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0026] Such as Figures 1 to 4As shown, a PCB board fixing fixture includes a base plate 100, a receiving groove 110, a retreat groove 120, a fixing groove 130, a ventilation groove 140, an elastic member 200, a movable portion 210, a bending portion 220, a supporting portion 230, a fastener 300 and an arc angle 400.

[0027] like Figures 1 to 5 As shown, a PCB board fixing fixture includes:

[0028] A substrate 100, wherein the substrate 100 is provided with a receiving groove 110 for receiving the PCB board 500, and a retreat groove 120 provided in a direction of the receiving groove 110 away from the PCB board 500, and the retreat groove 120 is communicated with the receiving groove 110;

[0029] The reinforcement structure includes an elastic member 200 detachably disposed on the substrate 100, and the elastic member 200 includes a movable portion 210 movably extending into the receiving groove 110. When the PCB board 500 is in the receiving groove 110, the movable portion 210 is in the retreat groove 120 and abuts against the PCB board 500. The arrangement of the elastic member 200 can, on the one hand, stably fix the PCB board 500 in the receiving groove 110 through the abutment between the movable portion 210 and the PCB board 500, effectively ensuring the stability of the fixation of the PCB board 500; on the other hand, the operator only needs to press the PCB board 500 into the receiving groove 110 to fix the PCB board 500, which greatly improves the efficiency of fixing the PCB board 500.

[0030] like Figures 1 to 3 As shown, the substrate 100 is rectangular and is provided with a receiving groove 110 for receiving the PCB board 500. The size and shape of the receiving groove 110 are adapted to the PCB board 500. Preferably, the receiving groove 110 is rectangular and is used to cooperate with the reinforcement structure to fix the PCB board 500.

[0031] In this embodiment, the accommodating groove 110 is provided with an arc corner 400. Preferably, four arc corners 400 are provided, which are respectively located at the four corners of the accommodating groove 110. On the one hand, the stress concentration at the corner of the accommodating groove 110 can be reduced, thereby reducing the risk of fatigue fracture of the substrate 100 at this position. On the other hand, it can facilitate the withdrawal of the tool and avoid the situation where the tool scratches the surface of the substrate 100 or is damaged itself.

[0032] In order to achieve the fixation of the PCB board 500 in coordination with the reinforcement structure, in the present embodiment, a retreat groove 120 is further provided on the base plate 100. The retreat groove 120 is provided in the direction of the accommodating groove 110 away from the PCB board 500, and the retreat groove 120 is communicated with the accommodating groove 110, so that the movable portion 210 of the elastic member 200 has space to retreat when under pressure, thereby effectively avoiding excessive squeezing of the PCB board 500, protecting the PCB board 500 from damage, and making it more convenient and easy to take out the PCB board 500.

[0033] In this embodiment, the retreat groove 120 is U-shaped, and its open side is connected to the accommodating groove 110. The retreat groove 120 extends in a direction perpendicular to the accommodating groove 110 and forms a height difference with the accommodating groove 110. This effectively avoids interference with the surface of the substrate 100 when the movable part 210 is pressed and moves obliquely toward the retreat groove 120, further ensuring the stability of the fixation of the PCB board 500 and the service life of the substrate 100.

[0034] In this embodiment, the substrate 100 also has a fixing groove 130 detachably connected to the support portion 230 . The fixing groove 130 is rectangular and is arranged adjacent to the retreat groove 120 to locate the installation position of the elastic member 200 , thereby improving the convenience of installing the elastic member 200 .

[0035] Preferably, in this embodiment, the fixing groove 130 is provided with an arc corner 400. Preferably, two arc corners 400 are provided, which are respectively located at the corners of the fixing groove 130. On the one hand, the stress concentration at the corner of the fixing groove 130 can be reduced, thereby reducing the risk of fatigue fracture of the substrate 100 at this position. On the other hand, it can facilitate the withdrawal of the tool and avoid the situation where the tool scratches the surface of the substrate 100 or is damaged itself.

[0036] In this embodiment, the substrate 100 is further provided with a venting groove 140 located below the receiving groove 110. The venting groove 140 is U-shaped, with its opening facing the retreat groove 120, and is respectively connected to the receiving groove 110 and the retreat groove 120. It not only helps to dissipate heat from the PCB and reduce air pressure fluctuations, but also makes it easier to take out the PCB 500 through the circulation of airflow.

[0037] like Figure 1 , Figure 3 , Figure 4As shown in the figure, in order to achieve efficient fixation of the PCB board 500, in this embodiment, a reinforcement structure is provided. The reinforcement structure includes an elastic member 200 detachably disposed on the substrate 100. The elastic member 200 includes a movable portion 210 movably extending into the accommodation groove 110. When the PCB board 500 is located in the accommodation groove 110, the movable portion 210 is moved into the relief groove 120 under the extrusion of the accommodation groove 110, and abuts against the PCB board 500 under the action of elastic deformation, so that the PCB board 500 is fixed in the accommodation groove 110. Compared with the prior art method of manually operating the fixing member, the elastic member 200 utilizes its own elastic deformation function, enabling the operator to simply press the PCB board 500 into the accommodation groove 110, and the movable portion 210 can automatically abut against the PCB board 500, greatly improving the fixing efficiency of the PCB board 500. In addition, by abutting against the side of the PCB board 500, the movable portion 210 greatly reduces damage to the surface of the PCB board 500 caused by the fixing member.

[0038] In this embodiment, the elastic member 200 is composed of a movable portion 210, a bent portion 220 and a support portion 230, and the movable portion 210, the bent portion 220 and the support portion 230 are integrally formed, effectively ensuring the overall structural strength and reliability of the elastic member 200, avoiding problems such as looseness or failure that may be caused by the assembly of multiple components, and improving the durability and consistency of the elastic member 200.

[0039] In this embodiment, the movable portion 210 is strip-shaped and vertically extends into the accommodation groove 110. One end thereof is connected to the bent portion 220, and the other end extends away from the bent portion 220. When the elastic member 200 is installed on the substrate 100, the movable portion 210 extends into the accommodation groove 110. When the PCB board 500 is placed, it is pressed, obliquely moves towards the relief groove 120, and presses against the bent portion 220. Then, under the action of the bent portion 220, it presses against the PCB board 500 in the reverse direction, achieving abutment against the side of the PCB board 500, thereby realizing the fixation of the PCB board 500.

[0040] In this embodiment, the bent portion 220 is arc-shaped and can undergo elastic deformation under pressure. It is fixedly connected to the end of the movable portion 210 away from the retraction groove 120. When the PCB board 500 is in the accommodation groove 110 and the movable portion 210 is pressed to apply pressure to the bent portion 220, the bent portion 220 drives the interaction portion to move towards the PCB board 500 by its own elastic deformation and applies a reverse pressure to the PCB board 500. Based on the characteristics of the elastic deformation of the bent portion 220, the movable portion 210 can continuously apply an appropriate pressure to the PCB board 500, and even in the case of external vibration or impact, the stable fixed state of the PCB board 500 can be maintained, effectively improving the stability of the fixation of the PCB board 500. In addition, the characteristics of this elastic deformation make the fixation form of this application a flexible fixation, avoiding unnecessary pressure or stress on the PCB board 500 and effectively protecting the integrity and functionality of the PCB board 500.

[0041] In this embodiment, the support portion 230 is connected to the end of the bent portion 220 away from the movable portion 210, and there is a movable gap between the support portion 230 and the movable portion 210. During the placement of the PCB board 500, the movable portion 210 is pressed and moves towards the support portion 230 into the retraction groove 120. It is used to support the movable portion 210 and the bent portion 220 to ensure the effectiveness of the movement of the movable portion 210.

[0042] In this embodiment, the support portion 230 is L-shaped, and its end away from the bent portion 220 is detachably connected to the fixing groove 130 of the substrate 100, realizing the detachable connection between the elastic member 200 and the substrate 100, making the maintenance of the entire fixing jig simple and fast. Damaged components can be replaced without complex tools, effectively reducing the maintenance cost.

[0043] In this embodiment, the support portion 230 forms a detachable connection with the fixing groove 130 through the fastener 300. Preferably, the fastener 300 is a screw. It effectively simplifies the installation process of the elastic member 200 and improves the assembly efficiency of the fixing jig.

[0044] To further improve the connection stability between the elastic member 200 and the substrate 100, in this embodiment, the support portion 230 includes a connection surface 231 that is detachably connected to the fixing groove 130. When the support portion 230 is installed on the fixing groove 130, the connection surface 231 fits with the fixing groove 130. The design of this connection surface 231 effectively expands the connection surface area between the elastic member 200 and the substrate 100, and further ensures the connection stability between the elastic member 200 and the substrate 100.

[0045] Preferably, in this embodiment, there are six sets of the relief grooves 120, the fixing grooves 130 and the elastic members 200, which correspond to each other one by one and are symmetrically arranged on both sides of the accommodating groove 110, further improving the stability of the fixing of the PCB board 500.
