[0040] In the embodiment of the present application, the circuit test component 30 is disposed on one side of the circuit board 20. The circuit test component 30 includes a circuit test head 31 and a flexible cable 32; the flexible cable 32 is between the circuit board 20 and the circuit test head 31. The first docking end of the flexible cable 32 is electrically connected to the docking end of the circuit board 20, and the second docking end of the flexible cable 32 is electrically connected to the circuit test head 31 and is used to test the device to be tested through the circuit test head 31; the flexible cable 32 has a flexible function and can be bent and deformed; the flexible cable 32 is bent and deformed as the position of the circuit test head 31 relative to the circuit board 20 is adjusted, so as to adapt to the position adjustment of the circuit test head 31 relative to the housing 10 through the flexible cable 32, and facilitate the circuit test head 31 to freely dock with the device to be tested, avoiding the influence of the circuit test head 31 by a rigid conductive member, and ensuring the position freedom of the circuit test head 31 of the circuit test device 100.

[0041] The circuit board 20 is built into the housing 10; the flexible cable 32 penetrates the housing 10 in a sealed manner, preventing liquid from entering the housing 10 through the connection between the flexible cable 32 and the housing 10, avoiding contact between the liquid and the circuit board 20, thus ensuring the performance of the circuit board 20.

[0047] The circuit test bracket 311 is arranged in the vertical direction and is provided for the flexible cable 32 to pass through. The second docking end of the flexible cable 32 is located in the receiving groove 311b, so that the second docking end of the flexible cable 32 can be docked with the circuit test piece 312 in the circuit test bracket 311 through the circuit test bracket 311.
