[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3 and 4, this utility model provides a technical solution: an FCT test fixture, comprising: an operating table 2 with a placement slot 16 on the top, the placement slot 16 corresponding to the detection terminal 15; a rotating plate fixedly connected to the end of the flip cover 3 and the top of the operating table 2, the rotating plates being rotatably connected by a rotating shaft; a flip drive unit placed on the top of the support frame 1, the flip drive unit including cylinder 8 and cylinder 9 rotatably mounted on the top of the operating table 2, the output ends of cylinder 8 and cylinder 9 being rotatably connected to the flip cover 3, used to drive the flip cover 3 to be in an inclined and horizontal state; a needle plate 14 being raised and lowered inside the flip cover 3, the bottom of the needle plate 14 being equidistantly fixedly connected to the detection terminal 15, and the top of the needle plate 14 being equipped with a drive unit for driving the detection terminal 15 to rise and fall.

[0024] It should be noted that in this invention, the board to be tested is placed inside the placement slot 16. The flip cover 3 is rotated from the tilted turntable to a horizontal state by the retraction of cylinders 8 and 9. After the rotation is completed, the needle plate 14 is driven to move downward by the drive unit, so that the needle plate 14 drives the detection terminal 15 to contact, and the detection terminal 15 and the corresponding device are used to perform corresponding detection on the board to be tested. After the detection is completed, cylinders 8 and 9 drive the flip cover 3 to rotate to a tilted state, which facilitates the prevention and collection of the board to be tested.

[0025] Please see Figure 1 , 2 As shown, a support frame 1 is fixed to the bottom of the control panel 2, and a display 4 is fixed to one end of the control panel 2 via a bracket.

[0026] It should be noted that during the testing of this utility model, the terminals make corresponding contact with the circuit board. Electrical testing instruments (such as multimeters, contact resistance testers, etc.) can be used to test electrical parameters such as terminal contact resistance and insulation resistance to ensure that they are within the specified range. The corresponding parameters are displayed on the display 4 for easy observation of the test results.

[0027] Please see Figure 1 , 2 As shown in Figures 3 and 4, both sides of the top of the operating table 2 are fixedly connected to the support side plates 10, and the fixed ends of cylinder 3 9 and cylinder 2 8 are rotatably connected to the support side plates 10.

[0028] It should be noted that the supporting side plate 10 of this utility model has an L-shaped structure, and the second cylinder 8 is located above the third cylinder 9. Both of them are rotatably connected to the supporting side plate 10. The output ends of the second cylinder 8 and the third cylinder 9 are rotatable with the flip cover 3. The flip cover 3, the second cylinder 8, the third cylinder 9 and the supporting side plate 10 form a quadrilateral structure. The flip cover 3 is flipped by the extension and retraction of the second cylinder 8 and the third cylinder 9.

[0029] Please see Figure 3 As shown, multiple positioning rods are fixed at the bottom of the flip cover 3, and positioning holes are provided on the top of the operating table 2 corresponding to the positions of the positioning rods. The diameter of the positioning holes is larger than the diameter of the positioning rods, and a rubber ring is installed on the top of the positioning holes.

[0030] It should be noted that when the flip cover 3 is flipped to a horizontal position, the positioning rod is first inserted into the rubber ring. When the flip cover 3 is in a horizontal position, the positioning rod is vertically inserted into the positioning hole. The inner diameter of the rubber ring is smaller than that of the positioning rod. In this way, the positioning rod is limited by the positioning hole of the rubber ring, which can limit the flip cover 3 and ensure its position accuracy after flipping.

[0031] Please see Figure 4 As shown, the drive unit includes a lifting cylinder 13 fixed inside the flip cover 3. The output end of the lifting cylinder 13 is fixedly connected to a lifting plate 11. A guide rod 12 is slidably connected to the middle of the lifting plate 11. The guide rod 12 is fixedly connected to the flip cover 3.

[0032] It should be noted that when the flip cover 3 is rotated to a horizontal state, the detection terminal 15 corresponds to the detection point of the test plate inside the placement groove 16. The lifting cylinder 13 drives the lifting plate 11 to rise and fall along the guide rod 12. The guide rod 12 drives the detection terminal 15 to move downward through the needle plate 14, so that the detection terminal 15 contacts the test plate and facilitates its detection.

[0033] Please see Figure 1 , 3As shown, a rotating hook 6 is rotatably connected to the bottom of the flip cover 3, and a fixed hook 5 that is interlocked with the rotating hook 6 is fixed to the top of the operating table 2. A cylinder 7 is rotatably connected to the bottom of the flip cover 3, and the output end of the cylinder 7 is rotatably connected to the rotating hook 6.

[0034] It should be noted that when the flip cover 3 of this utility model is flipped downwards, the cylinder 7 extends and drives the rotating hook 6 to flip outwards. When the flip cover 3 is horizontal, the cylinder 7 drives the rotating hook 6 to reset, so that the fixed hook 5 and the rotating hook 6 are engaged with each other. This ensures that during testing, the needle plate 14 and the detection terminal 15 are prevented from contacting the board to be tested, which would cause the flip cover 3 to loosen upwards, thus ensuring the stability of the contact point connection during testing.
