DETAILED DESCRIPTION
[0018] like Figures 1 to 3 As shown, a 6EANA nuclear test system card test device comprises a test base 1, a card clamping mechanism is arranged on the test base 1, the card clamping mechanism comprises two vertically arranged columns 2, the columns 2 are slidably arranged on the test base 1, the moving directions of the two columns 2 are opposite, and the spacing between the two columns 2 is adjusted, the opposite end surfaces of the two columns 2 are slidably arranged with strip card members 3, the opposite end surfaces of the two strip card members 3 are penetrated and opened with card slots 4 along their own height direction, and a conversion module is installed on the test base 1, and the conversion module is located between the two columns 2. The card is placed above the conversion module, and then the two columns 2 are moved. The columns 2 drive the bar card 3 to move close to the card, so that the card to be tested can be clamped by the two bar card 3. Since the two bar card 3 move in opposite directions and at the same speed, they have a centering clamping effect, and the card is clamped just above the conversion module. Finally, the bar card 3 is moved downward to drive the card to be plugged into the conversion module, thereby achieving the effect of positioning and clamping the card, ensuring that the card is accurately plugged into the conversion module. At the same time, it can also adapt to clamping cards of different sizes and models, thereby reducing the hardware cost of the card testing equipment. Preferably, the conversion module includes a conversion board 16, a female head 17 that is plugged into the card is provided on the top of the conversion board 16, a pin row is provided on the bottom of the conversion board 16, a socket hole is provided in the test base 1, the conversion board 16 is connected to the test base 1 by screws, the pin row is plugged into the socket hole, a circuit board is provided in the conversion board 16, the pin row and the female head 17 are both connected to the circuit board, a male head is provided at the bottom of the card, the male head is plugged into the female head 17, the electrical connection of the card is completed, so as to perform corresponding test operations, when the position of the male head of the card is different, the corresponding conversion module can be replaced, and the card clamping mechanism can adapt to various sizes and types of cards for clamping, and cooperate with the detachable design of the conversion module so that the test base 1 can adapt to various types of cards for test operations.
[0019] In some embodiments, Figure 1 and Figure 2As shown, elastic pads 5 are fixed on the two opposite inner walls of the slot 4, and the distance between the two elastic pads 5 is smaller than the thickness of the card, so that when the side of the card is assembled in the slot 4, the elastic pad 5 will be squeezed to produce deformation, so that the card and the elastic pad 5 are in an interference fit, which can stabilize the position of the card and make the card correspond to the conversion module. The end of the elastic pad 5 away from the column 2 is provided with a wedge surface 6, and the thickness of the elastic pad 5 at the wedge surface 6 gradually increases along the end close to the column 2. The maximum distance between the two elastic pads 5 at the wedge surface 6 is greater than the thickness of the card. In the process of inserting the card into the slot 4, it will first pass through the maximum distance between the two wedge surfaces 6, so that the card can be smoothly inserted into the slot 4. As the column 2 moves, the card squeezes the elastic pad 5 to deform and is completely assembled in the slot 4, completing the clamping and positioning of the card.
[0020] In some embodiments, Figure 2 As shown, rectangular grooves 7 are provided on the opposite end faces of the two columns 2, and the rectangular grooves 7 run through the height direction of the columns 2. The strip clamps 3 are slidably assembled in the rectangular grooves 7. A slide groove 8 is provided on the inner wall of the rectangular groove 7 along the height direction of the columns 2. A slide rail 9 is slidably arranged in the slide groove 8. The slide rail 9 is fixedly connected to the strip clamps 3. The movement of the strip clamps 3 is guided by the cooperation of the slide rail 9 and the slide groove 8, so that the strip clamps 3 move vertically, ensuring that the centered clamps can be smoothly plugged into the conversion module.
[0021] Furthermore, if Figure 1 As shown, one end of the column 2 away from the strip clamp 3 is threadedly connected with a fastening screw 15, and the tail of the fastening screw 15 is inserted into the rectangular groove 7 to press against the strip clamp 3. When the clamp is clamped, the fastening screw 15 presses against the strip clamp 3 to limit the upward and downward movement freedom of the strip clamp 3. When the two strip clamps 3 clamp the clamp above the conversion module, loosen the fastening screw 15 and move the strip clamp 3 downward, so that the strip clamp 3 drives the clamp to move downward and is inserted into the conversion module.
[0022] In some embodiments, Figure 1 and Figure 3 As shown, a screw groove 10 is provided on the top surface of the test base 1, and the screw groove 10 is located on one side of the conversion module. A bidirectional threaded screw 11 is rotatably arranged in the screw groove 10, and screw sliders 12 are threadedly mounted on the two threaded sections of the bidirectional threaded screw 11 with opposite thread rotation directions. The two columns 2 are respectively connected to the two screw sliders 12 through connecting rods 13, and one end of the bidirectional threaded screw 11 passes through the test base 1 and is fixed with a handwheel 14. The handwheel 14 is manually turned, and the handwheel 14 drives the bidirectional threaded screw 11 to rotate. Since the two screw sliders 12 are respectively threadedly mounted on the two threaded sections of the bidirectional threaded screw 11 with opposite thread rotation directions, the moving directions of the two screw sliders 12 are opposite, thereby driving the two bar clamps 3 to move at the same speed and in opposite directions, thereby achieving the effect of centering the clamps.
