[0002] Diesel is a light petroleum product with the advantages of high energy density and low fuel consumption rate. Therefore, transportation vehicles fueled by diesel are more powerful and have higher load capacity. At present, most diesel vehicles are equipped with corresponding electronic control devices, and information is transmitted between multiple electronic control devices through wiring harnesses. Therefore, wiring harnesses play a vital role as key electrical facilities for vehicle signal transmission and power supply.

[0003] In the related art, when an electronic control device of a diesel vehicle fails, a wiring harness tester is usually used as a wiring harness detection tool to detect the relevant wiring harness and diagnose the problem of the wiring harness by detecting the electrical parameters of the wiring harness. As the functions of electronic control devices become more and more complex, they have more and more wiring harnesses; therefore, the functions of wiring harness testers are becoming more and more comprehensive. During the detection process, a plurality of test lines are usually connected to the wiring port of the wiring harness tester to meet the detection needs of diesel vehicles. With the increase in the number of test lines, especially in the process of troubleshooting, the distribution of the test lines is relatively messy, which is not only prone to entanglement or knotting, but also difficult to find the required test lines, thereby reducing the detection efficiency of diesel vehicles.

[0021] The detector body 100 is further explained in combination with the aforementioned embodiment. The detector body 100 can be reasonably selected according to the actual application scenario and specific needs.

[0024] The rotating shaft 510 is further described in conjunction with the foregoing embodiment. The rotating shaft 510 can adopt a damping rotating shaft 510 with damping, which can improve the stability of the wire supporting plate 520 during use on the one hand, and can reduce the noise generated when adjusting the posture of the wire supporting plate 520 on the other hand, and has good practicality.

[0025] In some embodiments, the side wall of the wire accommodating groove 530 is protruded to form a limiting portion 530a for limiting the position of the test wire in the wire accommodating groove 530; see Figure 3 By protruding a limiting portion 530a on the side wall of the wire accommodating groove 530, the opening width of the opening of the wire accommodating groove 530 can be reduced, and the test line entering the wire accommodating groove 530 can be limited to prevent the test line from escaping from the wire accommodating groove 530 during the detection process, so as to ensure the organization effect of the test line; it should be noted that the limiting portion 530a and the wire supporting plate 520 can be formed by an integrated molding process, and the wire supporting plate 520 can be made of plastic or metal material, which will not be repeated here.

[0026] In some embodiments, a plurality of test line combing structures 500 are provided, and the extension direction of the line supporting plate 520 is perpendicular to the opening direction of the line receiving groove 530 provided on the line supporting plate 520; Figure 1 and Figure 3 Since the detector body 100 is provided with a plurality of wiring ports 100a, by providing a plurality of test line combing structures 500, it is convenient to partition and organize the test lines, so as to further improve the wiring harness organization effect; for example, by using a plurality of test line combing structures 500, test lines with different functions can be partitioned and organized, or by using a plurality of test line combing structures 500, test lines with different colors can be partitioned and organized, thereby improving the search efficiency of the test lines; in addition, by making the opening direction of the wire accommodating groove 530 perpendicular to the extension direction of the wire supporting plate 520, it is convenient to put the test line into the wire accommodating groove 530, and it is also convenient to take out the test line, thereby improving the refinement and neatness of the test line arrangement.

[0027] In some embodiments, the linkage flip cover 300 includes a blocking portion 310 and a connecting portion 320; the blocking portion 310 is rotatably connected to the connecting outer frame 200; the connecting portion 320 is arranged on the side of the blocking portion 310 and is hinged to the end of the traction rod group 400, and the positive projection of the connecting portion 320 on the blocking portion 310 is located inside the blocking portion 310.

[0028] See also Figure 2 and Figure 4 By combining the linkage flap 300 and the connecting outer frame 200, the wiring port 100a of the detector body 100 can be protected and covered to achieve a dustproof effect; wherein, the linkage flap 300 includes a blocking portion 310 and a connecting portion 320, the blocking portion 310 is rotatably connected to the connecting outer frame 200, and is fixedly connected to the connecting portion 320 hinged to the traction rod group 400, so that the linkage flap 300 can drive the traction rod group 400 to unfold synchronously during the rotation process, thereby driving the test line comb set on the traction rod group 400 The physical structure 500 corresponds to the wiring port 100a, that is, the wiring port 100a corresponds to the wire accommodating groove 530; when the linkage flip cover 300 is closed, the blocking portion 310 can block the opening of the connecting outer frame 200 to ensure the shielding effect of the wiring port 100a; in addition, by making the positive projection of the connecting portion 320 on the blocking portion 310 located inside the blocking portion 310, it is avoided that the linkage flip cover 300 interferes with the connecting outer frame 200 when rotating along the edge of the connecting outer frame 200, thereby ensuring the blocking effect of the connecting outer frame 200.

[0029] In some embodiments, the traction rod group 400 includes a first connecting rod 410 and a second connecting rod 420; both ends of the first connecting rod 410 are respectively hinged to the inner wall connecting the outer frame 200 and one end of the second connecting rod 420, and the other end of the second connecting rod 420 is hinged to the linkage flap 300.

[0030] See also Figure 1 and Figure 4 By applying the traction rod group 400, the opening of the linkage flap 300 can be limited to prevent the linkage flap 300 from being opened too much and colliding with the detector body 100. At the same time, the traction rod group 400 is connected to the test line combing structure 500, so that the traction rod group 400 can be unfolded or folded with the rotation of the linkage flap 300, thereby changing the position of the test line combing structure 500.

[0031] The traction rod assembly 400 includes a first connecting rod 410 and a second connecting rod 420 which are hinged to each other. Figure 1 As shown, when the linkage flip cover 300 is opened, the first link 410 and the second link 420 are driven to rotate along the hinge point of the two, so that the angle between the two gradually increases. When the extension directions of the first link 410 and the second link 420 are the same, the traction rod group 400 is fully unfolded. At this time, the test line combing structure 500 set in the traction rod group 400 is adapted to the wiring port 100a. By adjusting the use posture of the wire supporting plate 520 in the test line combing structure 500, the wire accommodating groove 530 can be made to correspond to the wiring terminal one by one; as shown in FIG. Figure 4 As shown, when the linkage flap 300 is closed, the linkage flap 300 drives the first link 410 and the second link 420 to rotate along the hinge point thereof, so that the angle therebetween gradually becomes smaller, until the first link 410 and the second link 420 are folded and stored in the connecting outer frame 200, and drives the test line combing structure 500 to be stored together, thereby improving the appearance refinement of the detection tool.

[0032] In some embodiments, the extension direction of the first connecting rod 410 and the extension direction of the second connecting rod 420 are both perpendicular to the extension direction of the wire supporting plate 520; Figure 1 and Figure 4 By making the extension direction of the first connecting rod 410 and the extension direction of the second connecting rod 420 perpendicular to the extension direction of the wire supporting plate 520, it can ensure that the traction rod group 400 drives the wire supporting plate 520 to move synchronously, and at the same time, it can also ensure that the arrangement direction of the accommodating cavity 200a on the wire supporting plate 520 corresponds to the arrangement direction of the wiring port 100a.

[0033] In some embodiments, the detection tool also includes a box lock component 600 for locking or unlocking the linkage flip cover 300; the box lock component 600 includes a hook 610, a linkage lock block 620 and a spring 630; the hook 610 is arranged on the linkage flip cover 300; the connecting outer frame 200 is provided with a accommodating cavity 200a and a socket 200b that are interconnected, the linkage lock block 620 and the spring 630 are both arranged in the accommodating cavity 200a, the linkage lock block 620 is connected to one end of the spring 630, and is adapted to the structure of the hook 610; the other end of the spring 630 abuts against the inner wall of the accommodating cavity 200a.

[0034] See also Figure 5 By applying the box lock structure in the detection tool, the linkage flip cover 300 in the closed state can be locked, and it is also convenient to unlock it when in use; specifically, the box lock component 600 includes a hook 610, a linkage lock block 620 and a spring 630. When the linkage flip cover 300 is in the closed state, the hook 610 set on the linkage flip cover 300 will enter the socket 200b. Since the socket 200b is connected to the accommodating cavity 200a, and the structure of the hook 610 is compatible with the structure of the linkage lock block 620, the hook 610 entering the socket 200b will apply pressure to the linkage lock block 620, drive the linkage lock block 620 to slide along the accommodating cavity 200a and compress the spring 630. When the hook 610 When it moves to the preset position, the linkage lock block 620 is no longer under pressure, and the linkage lock block 620 is pushed back to its original position by the elastic restoring force of the spring 630, so that the linkage lock block 620 clamps the hook 610, thereby locking the linkage flip cover 300; conversely, when the linkage flip cover 300 is unlocked, a thrust is applied to the linkage lock block 620 to move it in a direction away from the hook 610 and compress the spring 630, thereby releasing the locking effect on the hook 610, and the hook 610 can be driven to withdraw from the socket 200b by rotating the linkage flip cover 300. After the thrust is removed, the spring 630 will use its elastic restoring force to drive the linkage lock block 620 to return to its original position, thereby unlocking the linkage flip cover 300.

[0035] The hook 610 is further described in conjunction with the above-mentioned embodiment. Figure 5 As shown, the side of the hook 610 away from the flip cover can be set to an arc shape, so that the hook 610 can smoothly enter the socket 200b, and can apply a pressure in the direction of the linkage lock block 620 to drive the linkage lock block 620 to slide along the accommodating cavity 200a.

[0036] In some embodiments, the interlocking locking block 620 includes a fixedly connected driving portion 621 and a locking portion 622; the connecting outer frame 200 is also provided with a slide 200c connected to the accommodating chamber 200a, the driving portion 621 is slidably set in the slide 200c, and the locking portion 622 is slidably set in the accommodating chamber 200a, one end of the locking portion 622 is connected to one end of the spring 630, and the other end of the locking portion 622 is adapted to the structure of the hook 610.

[0037] See also Figure 5The linkage lock block 620 is slidably arranged on the connecting outer frame 200. By changing the position of the linkage lock block 620, the engaging state of the hook 610 can be adjusted, and then the linkage flip cover 300 is locked and unlocked; wherein the linkage lock block 620 includes a fixedly connected driving part 621 and a locking part 622, the driving part 621 is slidably arranged in the slideway 200c connected to the accommodating cavity 200a, so that the driving part 621 leaks out of the surface of the connecting outer frame 200, which is convenient for the staff to apply a thrust to the driving block through their fingers, thereby reducing the difficulty of unlocking; the locking part 622 can slide along the accommodating cavity 200a after being subjected to the elastic restoring force of the spring 630 or the thrust applied to the driving part 621. When moving in the direction close to the hook 610, the hook 610 can be locked by using one end adapted to the hook 610. When moving in the direction away from the hook 610 and compressing the spring 630, the locking effect on the hook 610 can be released.

[0038] The locking portion 622 is further explained in combination with the above-mentioned embodiment. Since the locking portion 622 is used to lock or unlock the hook 610, a guide slope can be provided at one end of the locking portion 622 close to the hook 610. The guide slope is inclined toward the socket 200b so that when the hook 610 enters the socket 200b, it can push the locking portion 622 to compress the spring 630, thereby realizing automatic locking of the hook 610; at the same time, an anti-slip groove can be provided on the side of the driving block away from the locking portion 622 to increase the friction when driving the linkage lock block 620 and reduce the difficulty of unlocking.
