It also supports customized wiring terminals for easy batch testing.

[0050] Embodiment 1:

[0051] See attached Figure 4 and Figure 5 The interior of the tester 1 is integrally provided with a mainboard box 111 for installing the mainboard box 4, the outer walls on both sides of one end of the mainboard box 111 are integrally provided with side shells 112, the outer walls on both sides of the other end of the mainboard box 111 are provided with arm straight grooves 113, the middle parts of the outer walls on both sides of the mainboard box 111 are fixedly provided with guide shells 114, and the outer wall of the mainboard box 111 and one side of the side shell 112 are penetrated by a straight rail groove 115.

[0052] See attached Figure 3 and Figure 4 The mainboard box 4 is detachably installed inside the mainboard box 111, and a wiring port 401 is provided at one end of the mainboard box 4. An active wiring board 5 is movably assembled inside the tester 1, and wiring terminals 501 are installed at the side walls of the active wiring board 5 and at positions corresponding to the corresponding wiring ports 401. The wiring terminals 501 are electrically connected to the corresponding power switch 101, harness test interface 102, LED display screen 103, indicator light 104, read and learn storage button 105, mode and setting multiplexing button 106, up button 107, down button 108 and internal equipment instrument 110 through wiring.

[0053] See attached Figure 4 and Figure 5 Block openings 402 are provided on both sides of the outer wall of the mainboard box 4 and at positions corresponding to the side shell 112, and straight slide grooves 403 are provided on both sides of the outer wall of the mainboard box 4 and at the same height as the straight rail groove 115. The two ends of the movable wiring board 5 are fixedly connected with end conductors 502, and one end of the end conductor 502 is slidably embedded in the corresponding arm straight groove 113.

[0054] See attached Figure 4 and Figure 6The two sides of the mainboard box 111 are symmetrically slidably assembled with unlocking slides 7 through the guide shell 114, and a spring 701 is connected between the side wall of the unlocking slide 7 and the side wall of the guide shell 114. Both sides of the top and bottom of one end of the unlocking slide 7 are penetrated with oblique guide grooves 702. The insides of the two side shells 112 are symmetrically slidably assembled with active clamping blocks 8, and both ends of the active clamping block 8 are fixedly connected with end rods that movably penetrate the oblique guide grooves 702.

[0055] See attached Figure 6 and Figure 7 , turntables 9 are symmetrically mounted on the outer walls of both sides of one end of the mainboard box 111, convex ring guide grooves 901 are fixedly arranged on the inner sides of the two turntables 9, and the other end of the end conductor 502 is slidably embedded in the corresponding convex ring guide grooves 901, and a bevel gear 2 902 is fixedly mounted on the outer wall of the turntable 9, and a side rod 903 is fixedly connected to the edge of the outer wall of the turntable 9, and a spherical end 904 is fixedly arranged at the end of the side rod 903; motors 6 are fixedly mounted inside the tester 1 and on both sides of the mainboard box 111, and a bevel gear 1 601 meshing with the bevel gear 2 902 is fixedly mounted at the end of the output shaft of the motor 6.

[0056] According to the above structure, when the tester 1 has a short circuit, a line overload or an overtemperature, in order to protect the important data information inside the mainboard box 4, the control circuit will control the motor 6 to work, and the turntable 9 will be driven to rotate through the engagement of the bevel gear 1 601 and the bevel gear 2 902. Since the other end of the end conductor 502 is slidably embedded in the corresponding convex ring guide groove 901, according to the shape of the convex ring guide groove 901, the active wiring board 5 at this time will move away from the mainboard box 4, and the wiring terminal 501 will be disconnected from the corresponding wiring port 401, and the operation of the chip and hard disk inside the mainboard box 4 will be stopped urgently, thereby avoiding damage to the internal parts or circuits; in the above process, the unique structure of the mainboard box 4 and the active wiring board 5 changes the internal integrated structure of the traditional tester 1, and can stop the operation of the internal components of the mainboard box 4 in time when the circuit is abnormal, so as to avoid damage to the internal chip and motherboard as much as possible, and ensure the safety of the detection data.

[0057] See attached Figure 6 and Figure 7 The two sides of the mainboard box 111 are symmetrically slidably assembled with pop-up push plates 10 through straight rail grooves 115, and a spring 1001 is connected between the side wall of the pop-up push plate 10 and the side wall of the side shell 112, and the inner branch end of the pop-up push plate 10 passes through the straight rail groove 115 and is inserted into the corresponding straight slide groove 403; the inner walls on both sides of the tester 1 are movably assembled with an unlocking frame 11 through a spring telescopic tube 1101, and the side wall at one end of the unlocking frame 11 is provided with a block 1102 for blocking the pop-up push plate 10.

[0058] According to the above structure, when the temperature sensor detects that the internal temperature of the tester 1 is too high, in order to avoid the influence of electrical fire on important data, the turntable 9 is also driven to rotate by the motor 6, but the angle of the turntable 9 is greater than the above, and the movable wiring board 5 will continue to move after being separated from the main board box 4 until it moves to the limit distance. At this time, the side rod 903 will squeeze one end of the unlocking slide 7 and make it slide, and according to the direction of the inclined guide groove 702, the active card block 8 will be separated from the inside of the card block mouth 402 and move to the inside of the side shell 112 and squeeze the spring inside it; then, the turntable 9 continues to rotate so that the spherical end 904 is in contact and squeezed with the unlocking frame 11, and the spring expansion tube 1101 will shrink accordingly, and the stopper 1102 that originally blocked the push plate 10 will also move away from the push plate 10. At this time, the push plate 10 will move quickly under the elastic force of the second spring 1001 in the stretched state, and finally the mainboard box 4 will leave the inside of the tester 1 under the push of the push plates 10 on both sides, achieving the effect of safe pop-up. The above process can automatically and safely pop out the mainboard box 4 from the inside of the tester 1 when an extreme accident occurs, so as to avoid damage as much as possible, greatly reduce the possibility of equipment damage, and further ensure the safety of test data. The structure used to control the disconnection and pop-up of the mainboard box 4 is the same, the structure is compact, and the use space inside the equipment is optimized.

[0059] The working principle of the present invention is as follows: when the tester 1 is short-circuited, the line is overloaded or the temperature is too high, in order to protect the important data information inside the mainboard box 4, the control circuit will control the motor 6 to work, and the turntable 9 is driven to rotate through the meshing of the bevel gear 1 601 and the bevel gear 2 902. Since the other end of the end conductor 502 is slidably embedded in the corresponding convex ring guide groove 901, according to the shape of the convex ring guide groove 901, the active wiring board 5 will move away from the mainboard box 4 at this time, and the wiring terminal 501 is disconnected from the corresponding wiring port 401, and the operation of the chip and hard disk inside the mainboard box 4 will be stopped urgently, thereby avoiding damage to the internal parts or circuits;

[0060] When the temperature sensor detects that the temperature inside the tester 1 is too high, in order to avoid the influence of electrical fire on important data, the turntable 9 is also driven to rotate by the motor 6, but the angle of the turntable 9 is greater than the above. After the movable terminal block 5 is separated from the main board box 4, it will continue to move until it moves to the limit distance. At this time, the side rod 903 will squeeze one end of the unlocking slide 7 and make it slide, and according to the direction of the inclined guide groove 702, the active card block 8 will move to the inside of the side shell 112 and squeeze the spring inside it; then, the turntable 9 continues to rotate to cause the spherical end 904 to contact and squeeze the unlocking frame 11, and the spring expansion tube 1101 will shrink accordingly, and the block 1102 that originally blocked the push plate 10 will also move away from the push plate 10. At this time, the push plate 10 moves rapidly under the elastic force of the second spring 1001 in the tension state, and finally the main board box 4 will leave the inside of the tester 1 under the push of the push plates 10 on both sides, achieving a safe ejection effect.

[0064] According to the above structure, when it is necessary to detect multiple wires 13 to be tested, each wire 13 to be tested is first placed in the wire slot, and then the middle of each wire 13 to be tested is pressed into the top of the active slot block 1205 through the wire pressing plate 1203. At this time, the active slot block 1205 will be in a fixed connection with the corresponding wire 13 to be tested. When it is necessary to test a certain wire 13 to be tested separately, the wire 13 to be tested is pulled, and the corresponding active slot block 1205 will move along the guide rod 1204 toward the end slot body 1201 and squeeze the spring 4 1208, and the corresponding positioning block 120 6 is pushed into the positioning hole 1209, the pulled-out length of the wire 13 to be tested is fixed, and when the wire 13 to be tested needs to be reset, it is only necessary to press the corresponding push rod 1210, and the push rod 1210 will push the positioning block 1206 out of the positioning hole 1209, and then the wire 13 to be tested will be reset under the elastic force of the spring four 1208; in the above process, the design of the wire harness organizer 12 is convenient for the test personnel to organize a plurality of wires to be tested 13, avoid the situation of re-inspection of multiple wires to be tested 13 during detection, and is convenient for the overall personnel, facilitating the detection work of the staff.
