[0037] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0038] An embodiment of the present application discloses a testing tool for a tile-type component.

[0039] A test fixture for a tile-type component includes a heat dissipation component 1, a fixing frame 2 and a base 3. The test signal input end of the tile-type component is located on the heat dissipation surface of the tile-type component, while the test signal output end is located on the side of the tile-type component away from the heat dissipation surface. The function of the heat dissipation component 1 is to dissipate heat for the tile-type component. The tile-type component is fixed on the heat dissipation component 1 by a clamping unit 13 to ensure that the heat dissipation surface of the tile-type component is in close contact with the heat dissipation component 1. The function of the fixing frame 2 is to fix the connector of the signal input cable 4 of the tile-type component and to move along a specific route through the driving unit 21 to realize the plugging of the connector of the signal input cable 4 of the tile-type component with the test signal input end of the tile-type component, thereby improving the convenience of connecting the signal input cable 4 and the test signal input end of the tile-type component. The base 3 is located at the bottom of the heat dissipation component 1 and is used to support the heat dissipation component 1.

[0040] Before testing the tile-type component, first fix the tile-type component to the heat dissipation component 1 through the pressing unit 13 to ensure that the heat dissipation surface of the tile-type component is in close contact with the heat dissipation component 1. Then, operate the fixing frame 2 through the driving unit 21 to plug the signal input cable 4 of the tile-type component into the test signal input end of the tile-type component to improve the convenience of connection. At the same time, the signal output cable of the tile-type component is also plugged into the test signal output end of the tile-type component. During the test, the heat dissipation component 1 further dissipates heat on the heat dissipation surface of the tile-type component to improve the heat dissipation effect.

[0041] The heat dissipation assembly 1 includes a heat conducting base 11 and a heat dissipation unit 12 .

[0042] The thermal base 11 is fixed on the base 3 and is used to transfer the heat of the tile-type component. The thermal base 11 is in contact with the heat dissipation surface of the tile-type component. A movable channel 112 for the movement of the fixing frame 2 is provided on the side of the thermal base 11 close to the tile-type component, and the test signal input end of the tile-type component is placed inside the movable channel 112. A plurality of ventilation holes 111 are provided on the thermal base 11, and the hole walls of two adjacent ventilation holes 111 form heat dissipation fins. The heat dissipation unit 12 is used to dissipate heat and cool the thermal base 11. In this embodiment, the heat dissipation unit 12 is a heat dissipation fan, which is used to accelerate the airflow through the heat dissipation fins and improve the heat dissipation effect of the heat dissipation fins.

[0043] The heat of the tile-type component is transferred from its heat dissipation surface to the heat conducting base 11, which increases the heat dissipation area through the heat conducting base 11, thereby improving the heat dissipation effect. At the same time, multiple cooling fans further improve the heat dissipation effect of the heat dissipation fins by accelerating the flow rate of the airflow.

[0044] The compression unit 13 includes a positioning frame 131 and a cover plate 132. The positioning frame 131 is screwed onto the thermal base 11 and is used to position and position the tile assembly. The cover plate 132 is screwed onto the positioning frame 131 and is used to press the tile assembly against the thermal base 11. The cover plate 132 includes a connection hole 133 for connecting the signal output cable to the test signal input terminal of the tile assembly.

[0045] When installing the tile assembly, place the tile assembly inside the positioning frame 131 and ensure that the heat dissipation surface of the tile assembly is in contact with the thermal base 11. Then, place the cover plate 132 on the tile assembly and secure it to the positioning frame 131 with screws. The screws pass through the cover plate 132 to press the tile assembly against the thermal base 11.

[0046] The fixed frame 2 is located within the movable channel 112 and slidably engages with the movable channel 112. The drive unit 21 includes a rack 22, a drive tooth 23, and a drive member 24. The rack 22 is fixedly mounted on the inner wall of the movable channel 112 of the heat dissipation assembly 1. The drive tooth 23 is mounted on the fixed frame 2 and rotates with the fixed frame 2. The drive tooth 23 meshes with the rack 22. The drive member 24 drives the drive tooth 23 to rotate.

[0047] The driving member 24 includes a positioning sleeve 241, a transmission rod 242 and a cap 243. The positioning sleeve 241 is located inside the fixing frame 2. In order to improve the working stability of the positioning sleeve 241, a plurality of locking holes 25 are provided on the fixing frame 2. The locking holes 25 are internally threaded with locking bolts. The ends of the locking bolts are used to tighten against the outer peripheral surface of the positioning sleeve 241, thereby reducing the possibility of movement of the positioning sleeve 241. The transmission rod 242 coaxially passes through the positioning sleeve 241 and rotates with the positioning sleeve 241, and one end of the transmission rod 242 is fixedly connected to the driving tooth 23. When it is necessary to move the fixing frame 2, the operator rotates the cap 243, and the cap 243 drives the driving tooth 23 to rotate through the transmission rod 242. The rotating driving tooth 23 moves relative to the rack 22, thereby realizing the movement of the fixing frame 2 and completing the insertion of the signal input cable 4 of the tile-type component and the test signal input end of the tile-type component.

[0048] At the same time, an opening is provided on the base 3 for the signal input cable 4 to pass through. The signal input cable 4 of the tile-type component can be placed inside the movable channel 112 through the opening of the base 3, thereby improving the convenience of moving the signal input cable 4 of the tile-type component.

[0049] The implementation principle of a testing tool for a tile-type component in the embodiment of the present application is as follows:

[0050] When placing the tile-type component, place the tile-type component inside the positioning frame 131, and ensure that the heat dissipation surface of the tile-type component fits in with the thermal seat 11, and press the tile-type component against the thermal seat 11 through the cover 132. Before testing the tile-type component, the signal output cable of the tile-type component is plugged into the test signal output end of the tile-type component through the connection hole 133 on the cover 132. Then, the operator rotates the cap 243, and the cap 243 drives the drive gear 23 to rotate through the transmission rod 242. The rotating drive gear 23 moves relative to the rack 22, thereby realizing the movement of the fixing frame 2 and completing the plugging of the signal input cable 4 of the tile-type component with the test signal input end of the tile-type component. During the test, the heat of the tile-type component is transferred from its heat dissipation surface to the thermal seat 11, and the heat dissipation area of ​​the heat is increased through the thermal seat 11, thereby improving the heat dissipation effect. At the same time, multiple cooling fans further improve the heat dissipation effect of the heat dissipation fins by accelerating the flow rate of the airflow.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
