[0035] The top of the test movable seat 122, the top of the tensile test table 11 and the top of the test socket 123 are all in the same plane;

[0036] Four indicator lights 127 are arranged on the top of the test movable seat 122, and the four indicator lights 127 correspond to the two first wires 1023 and the two second wires 1024 one by one;

[0037] A control button 128 is disposed on the top of the test movable seat 122, and the control button 128 is connected to the tension locking member 126;

[0038] There are four tension reset members 125, and the four tension reset members 125 are distributed circumferentially with the test movable seat 122 as the center;

[0039] The tension reset member 125 includes a tension reset block 1251, a tension guide rod 1252 and a tension reset spring 1253. The tension reset block 1251 is fixedly arranged on the test movable seat 122. The tension reset block 1251 is located below the tension test bench 11. The tension guide rod 1252 vertically passes through the tension reset block 1251. The top end of the tension guide rod 1252 is arranged on the tension test bench 11. The tension reset spring 1253 is located between the tension test bench 11 and the tension reset block 1251. The two ends of the tension reset spring 1253 are respectively connected to the tension test bench 11 and the tension reset block 1251. The tension reset spring 1253 is sleeved on the tension guide rod 1252.

[0040] A tension limiting block 1254 is fixedly provided at the bottom end of the tension guide rod 1252, and the tension limiting block 1254 abuts against the bottom of the tension reset block 1251;

[0041] The wiring harness 102 includes a connection terminal 1021, two first wires 1023 and two second wires 1024, and the ends of the two first wires 1023 and the ends of the two second wires 1024 are both connected to the connection terminal 1021;

[0042] The specific operation method is: insert the connecting terminal 1021 into the tension detection slot, then press the control button 128 to make the electric push rod 1262 drive the locking block 1261 to move, and make the locking block 1261 press against the connecting terminal 1021 to achieve the locking between the connecting terminal 1021 and the test socket 123, and then, plug the end of the first wire 1023 with a connector and the end of the second wire 1024 with a connector into the connecting terminal 1021. Here, each time a wire is plugged in, it is necessary to manually pull the wire upwards. When the wire connection terminal 1021 is connected reliably, the test socket 123 and the test movable seat 122 are driven to rise, and at the same time, the tension reset block 1251 is driven to rise synchronously on the tension guide rod 1252, and the tension reset spring 1253 is formed. During the rising of the tension movable seat, the tension detector 124 detects the tension signal. When the tension signal reaches the set value, the indicator light 127 corresponding to this wire lights up, that is, the tension of this wire is qualified, the hand and this wire are released, and the tension reset block 1251 is lowered and reset through the elastic action of the tension reset spring 1253, and the tension reset block 1251 is abutted against the tension limit block 1254. The reset of the tension reset block 1251 drives the test socket 123 and the test movable seat 122 to descend and reset. When all four indicator lights 127 are lit, press the control button 128 again to make the electric push rod 1262 drive the locking block 1261 to move in the opposite direction, and make the locking block 1261 stop pressing the connecting terminal 1021, so that the connecting terminal 1021 can be taken out from the placement;

[0043] Among them, only when all four indicator lights 127 are lit, pressing the control button 128 again can unlock the connection terminal 1021, so that missed detection can be avoided;

[0044] An adjusting component 129 is provided in the tension detection groove, and the adjusting component 129 is located below the tension locking member 126. The adjusting component 129 is used to adjust the insertion depth of the connecting terminal 1021 into the tension detection groove;

[0045] The adjustment component 129 includes a lifting plate 1291 and a lifting unit 1292. The tension detection slot extends to the bottom of the test socket 123. The lifting plate 1291 is connected to the inner wall of the tension detection slot by sliding up and down. The lifting unit 1292 is used to drive the lifting plate 1291 to move up and down. After the connection terminal 1021 is inserted into the tension detection slot, the bottom of the connection terminal 1021 abuts against the top of the lifting plate 1291. When the insertion depth of the connection terminal 1021 needs to be adjusted, the lifting plate 1291 is driven to move up and down by the lifting unit 1292, so that the insertion depth of the connection terminal 1021 into the tension detection slot can be adjusted.

[0046] The lifting unit 1292 includes a fixed block 12921, a lifting rod 12922 and a positioning pin 12923. The lifting rod 12922 is vertically fixed at the bottom of the lifting plate 1291.

The lifting rod 12922 is provided with a plurality of pin holes 12924, and the plurality of pin holes 12924 are distributed from top to bottom. The positioning pin 12923 passes through one of the pin holes. 2923 passes through the fixed block 12921, and the fixed block 12921 is locked with the lifting rod 12922 through the positioning pin 12923 to prevent the lifting rod 12922 from moving up and down. When the lifting plate 1291 needs to be lifted or lowered, the positioning pin 12923 is pulled out to make the lifting rod 12922 rise or fall on the fixed block 12921. The lifting and lowering of the lifting rod 12922 drives the lifting plate 1291 to rise or fall synchronously. When the position of the lifting plate 1291 is adjusted, the positioning pin 12923 is passed through the fixed block 12921 and the pin hole 12924 at the corresponding position.

[0047] In summary, during the tension test, the connection terminal 1021 can be removed from the tension detection slot only after all the wires have been tension tested, to avoid missed detection.
