The sensor 19, As shown in Figure 6. At least one set of bidirectional clamping screw rods 72 is installed on the clamping assembly 74 in the front and rear, and a left-handed nut 77 and a right-handed nut 78 are respectively installed on the two bidirectional clamping screw rods 72 of each group, and two left-handed nuts 77 and two A clamping plate 71 is installed on the upper part of each right-handed nut 78; the position of each set of bidirectional clamping screw rods 72 corresponds to the position of the terminal 41 on the terminal 4. The terminal structure is shown in Figure 11, and the clamping screw rod 72 There are multiple groups of connecting posts 41 in the accompanying image. A clamping block 73 is installed on the inner side of the clamping plate 71 , and the clamping block 73 is made of soft material. As shown in FIG. 9 , the height adjustment screw rod 173 is installed in the up and down direction of the adjustment plate 174 , the two ends of the clamping assembly 74 are respectively sleeved on the height adjustment screw rod 173 , and the upper part of the clamping assembly 74 is installed with a locking nut 172 to lock it tightly. The nut 172 is installed on the height adjustment screw rod 173 , and the height adjustment knob 171 is installed on the upper end of the height adjustment screw rod 173 .

A guide jig 8 is installed on the lower side of the clamping jig 7 between the two vertical plates 5. As shown in FIG. It is fixed on the vertical plate 5 by the locking knob 85 , a guide roller 83 corresponding to each group of clamping screw rods 72 is installed on one installation rod 81 , and an auxiliary roller 84 is installed on the other installation rod 81 in cooperation with the guide roller 83 . The roller 83 and the auxiliary roller 84 are provided with annular grooves 82 with matching positions.

In this embodiment, the device is provided with six groups of test units (ie, six groups of clamping screw rods 72 ), so that multiple groups of tests can be performed simultaneously. As shown in Figure 1, the test cable 2 has a plug 1 at one end. When in use, insert the test cable 2 between the clamping blocks 73, the plug 1 is clamped on the upper part of the clamping fixture 7, and then turn the first clamping knob by turning the first clamping knob. 75 and the second clamping knob 76 reduce the distance between the brackets of the two clamping blocks 73. By operating a set of knobs at the same time, the clamping block 73 can be opened and clamped. During the test, the test cable 2 is clamped by the clamp. The middle of the block 73 is passed through, and then the clamping is completed. The clamping block is made of soft material, which will deform during clamping to protect the cable. Use the principle of double screw live lock to ensure tight clamping, prevent the product from falling off, and clamp the test cable 2. The height of the clamping fixture 7 can be achieved by the height adjustment knob 171 driving the height adjustment screw 173 to rotate. When the height adjustment screw 173 rotates, the clamping nut 172 is used to drive the clamping assembly 74 to rise and fall.

The lower end of the test cable 2 is fixed by the terminal 41 of the terminal 4. In order to check whether the circuit in the cable is normal, one end of the cable needs to be connected to the system, and a terminal that can be quickly plugged is set. If there is damage, the system can detect and feedback in time. A weight 9 is fastened to the middle of the test cable 2 . The test cable passes through a set of guide rollers 83 and auxiliary rollers 84 on the guide jig 8 corresponding to the lower part of the clamping jig 7. The guide roller 83 and the ring groove 82 of the auxiliary roller 85 form a limit, which can prevent the cable from escaping guide range. When the cable passes through, the auxiliary roller 84 is rotated, and the cable can pass through the gap created by the reserved cut surface, and the operation is relatively fast.

The clamping fixture 7 adopts a twin-screw interlocking design to avoid the problem of cables falling off during the test. A guide wheel set jig 8 is set to standardize the movement of the cables during the test, so as to prevent the cables from entangling or interfering with each other. The test system is driven by a servo motor, which provides the system with a stable and accurate running track, which greatly improves the stability of the system. Multiple groups of test units can simultaneously carry out the test requirements of different types of products with different test requirements. Through the setting of test parameters, the test experiments for different types of products can be achieved in the same test process.
