Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1-5, an FCT test fixture comprises a base 1, wherein a workbench 2 is arranged on the base 1, sliding components 3 are arranged on two sides of the workbench 2, a detection component 4 is arranged on the sliding components 3, and the detection component 4 is used for testing a board to be tested 16; the heat dissipation assembly 5 is arranged in the base 1, and the heat dissipation assembly 5 is used for performing air cooling heat dissipation on the workbench 2.

Further, the sliding component 3 comprises a sliding rail 6, the sliding rail 6 is fixedly arranged on the workbench 2, a sliding block 7 is slidably connected to the sliding rail 6, and a carrier plate 8 is fixedly connected to the top end of the sliding block 7.

Specifically, a side-plug quick clamp 9 is connected to one side of the carrier plate 8, and a side-press handle 10 is arranged on the side-plug quick clamp 9.

Further, a mounting groove 11 is formed in the workbench 2, and a side-inserted quick clamp 9 is fixedly arranged in the mounting groove 11.

Further, the support plate 12 is fixedly arranged on two sides of the support plate 8, the support plate 12 is fixedly connected with the mounting plate 13, the pressing rapid clamp 14 is arranged on the mounting plate 13, the bottom of the pressing rapid clamp 14 is connected with the needle plate 15, and a plurality of detection probes are distributed at the bottom of the needle plate 15.

Specifically, a detection groove is formed in the carrier plate 8, and the detection groove is used for placing the board 16 to be detected.

Further, the heat dissipation assembly 5 includes a pair of mute fans 17, one end of each mute fan 17 is connected with a fan plate 1818, the other end of each mute fan 17 is connected with a fan support 19, the bottom of each fan support 19 is connected with a fixing plate 20, and heat dissipation fins 21 are arranged on the outer side of each fan support 19, so that the temperature of the surface of the workbench 2 can be reduced through the arrangement, and the heat dissipation fins 21 and the mute fans 17 are combined to form a common heat dissipation solution, so that the heat dissipation assembly is particularly suitable for application scenes requiring efficient heat dissipation while keeping low noise level. By using the heat sink 21 in combination with the silent fan 17, a better heat dissipation effect and good noise control can be achieved. When the device generates heat, the heat sink 21 conducts heat from the heat source to the surface and facilitates the dissipation of heat by increasing the surface area of the heat sink 21. But even if the surface area of the heat sink 21 is large, the heat dissipation effect may be limited if convection of the surrounding environment is insufficient. The introduction of the silent fan 17 at this time can provide additional convection heat transfer and accelerate heat transfer and dissipation. The mute fan 17 typically employs advanced bearing technology, fan blade design, and optimized circuit control to achieve low noise levels. The silent fan 17 generates less noise when operated, and can provide a quieter working environment, as compared with a conventional fan. In designs where the heat sink 21 is combined with the silent fan 17, the heat sink 21 is typically mounted above or to the side of the heat source, while the silent fan 17 blows air through the heat sink 21 by wind. Thus, the convection heat exchange effect can be effectively increased, the heat dissipation is quickened, and the relatively low noise level is kept. Heat radiation effect: the silent fan 17 provides additional air flow, helps the heat sink 21 to dissipate heat more effectively, and improves the heat dissipation effect. Noise control: the low noise design of the silent fan 17 reduces noise generated during operation and provides a quieter operating environment. The space is compact: the combination of the heat sink 21 and the silent fan 17 makes the overall heat dissipation solution more compact, suitable for space-limited devices and systems.

In this embodiment, a plurality of heat dissipation holes 22 are further formed on two sides of the base 1, and the heat dissipation holes 22 are formed on two sides of the heat dissipation component 5 to form a heat dissipation air channel, so that air flow can be enhanced, and the heat dissipation effect of the jig can be increased.

Further, the workbench 2 is further provided with power supplies 23, in this application, the power supplies 23 are provided with four blocks, and each power supply 23 is arranged at the upper end of the workbench 2.
