As an important part of the high-voltage platform of electric vehicles, the high-voltage resistance performance of aluminum substrates directly affects the safety and reliability of electric vehicles. Therefore, in the electrical testing process of aluminum substrates, it is not only necessary to 100% detect the open and short circuits of the circuits, but also to measure their high-voltage resistance performance.

The first test component 2 includes a bottom plate 201, and the bottom of the bottom plate 201 is fixedly connected to the top of the base 1; a second test component 3, which is arranged at the center of the bottom of the connecting plate 6. The second test component 3 includes a top plate 301, and the top of the top plate 301 is fixedly connected to the bottom of the connecting plate 6.

[0023] As Figures 1-2 and Figure 4 shown, first fixing columns 202 are symmetrically and fixedly connected to the top of the bottom plate 201 near the two side edges respectively. The tops of multiple first fixing columns 202 are fixedly connected to a lower fixture 204. Multiple first probes 205 are evenly arranged at the center of the top of the lower fixture 204, which is convenient for multiple first probes 205 evenly arranged on the top of the lower fixture 204 to be in contact connection with the aluminum substrate during testing for testing it.

[0024] As Figures 1-2 and Figure 4 shown, multiple positioning pins 203 are evenly and fixedly connected to the top of the bottom plate 201 near the four corner positions respectively. The outer surfaces of multiple positioning pins 203 penetrate the bottom of the lower fixture 204 and extend upward. By multiple positioning pins 203 penetrating the lower fixture 204, the aluminum substrate can be quickly positioned through multiple positioning pins 203.

[0025] As Figures 1-3 and Figure 4 shown, second fixing columns 302 are symmetrically and fixedly connected to the bottom of the top plate 301 near the two side edges respectively. The bottoms of multiple second fixing columns 302 are fixedly connected to an upper fixture 303. Multiple second probes 305 are evenly arranged at the center of the bottom of the upper fixture 303, which is convenient for multiple second probes 305 to contact the top of the aluminum substrate for testing when the upper fixture 303 moves downward.

[0026] As Figures 3-4 shown, multiple positioning holes 304 are evenly opened at the bottom of the top plate 301 near the four corner positions respectively. The positioning holes 304 are arranged in a matching manner with the positioning pins 203, which is convenient for the two fixtures to be accurately docked under the cooperative action of the positioning pins 203 and the positioning holes 304.

When the test of the aluminum substrate fails between the upper fixture 303 and the lower fixture 204, an alarm sound is emitted through the buzzer 9 to facilitate quick intervention by personnel.

[0028] As Figure 1 and 4 As shown, sliding sleeves 5 are fixedly connected to the inner surface of the connecting plate 6 near the four corner positions. The inner surface of the sliding sleeve 5 is slidably connected to the outer surface of the fixed rod 4, which facilitates the fixed setting of the sliding sleeve 5 on the inner surface of the connecting plate 6, enabling it to slide on the surface of the fixed rod 4 through the sliding sleeve 5 and improving the sliding effect of the connecting plate 6.

[0029] Usage method and working principle of the device: During the high-voltage test of the aluminum substrate, both the lower fixture 204 and the upper fixture 303 are made of high-voltage-resistant insulating materials. A plurality of first probes 205 and second probes 305 are respectively and evenly arranged on their opposite surfaces. The probes are made of high-voltage-resistant metal materials and are respectively connected to external high-voltage-resistant wires. The spacing and positions of the plurality of probes correspond to the circuit design of the aluminum substrate to ensure that every test point required on the aluminum substrate can be comprehensively and accurately contacted. Place the aluminum substrate to be tested on the top of the lower fixture 204, and align the round holes for positioning at the edge of the aluminum substrate with the plurality of positioning pins 203 and then place it in. Guide the aluminum substrate to the positioning position on the lower fixture 204. A plurality of first probes 205 all abut against the contact points at the bottom of the aluminum substrate. The front end of the probe is used to contact the aluminum surface or the copper surface of the circuit layer of the aluminum substrate, and the rear end is connected to the high-voltage-resistant wire. Start the electric telescopic rod 8. When its telescopic end 8 drives the connecting plate 6 to move downward, the connecting plate 6 smoothly slides downward on the outer surfaces of the plurality of fixed rods 4 through the plurality of sliding sleeves 5. The upper fixture 303 is fixed below the top plate 301 through a plurality of second fixing columns 302. When the upper fixture 303 gradually abuts against the aluminum substrate, the tops of the plurality of positioning pins 203 will gradually extend into the plurality of positioning holes 304 to guide the upper fixture 303 to accurately abut against the top of the aluminum substrate, so that a plurality of second probes 305 will accurately contact the contact points at the top of the aluminum substrate. When a high-voltage current is connected through the plurality of probes, personnel stay away from the test fixture. If the test fails, the high-voltage power supply end will emit an alarm buzzer sound through the buzzer 9 provided on the front side of the top block 7 to prompt personnel to quickly intervene and cut off the power supply. Personnel can safely and quickly identify defective products. During the test process, when the power supply of personnel is disconnected, place the test aluminum substrate, and drive the lower fixture 204 to move downward through the electric telescopic rod to automatically close the two fixtures, avoiding personnel contact with high-voltage equipment and improving the safety of the high-voltage test fixture for aluminum substrates.
