[0002] During the use of the engine, there is a problem of poor contact between the sensor and the male and female connectors of the wiring harness, which seriously affects the user experience. In order to improve the stability of the sensor and connector plugging, the plug-in force test will be carried out during the product development.

[0003] During the plugging and unplugging force test, the sensor and male connector are placed at the bottom and clamped by a vise; the female connector is placed at the top, and the female connector is connected to the upper clamping device through a binding cable. The plugging and unplugging force test is performed by controlling the upper clamping device to move up and down.

[0004] However, the above technology has the following problems:

[0005] 1. When testing the insertion force, the vertical centering between the plug-ins cannot be guaranteed. Due to the complex matching of the internal structure, the insertion force measured at this time will be too large;

[0006] 2. The cable itself has a certain expansion and contraction rate. When testing the pull-out force, the cable will be pulled first because it needs to overcome the resistance between the plug-ins. At this time, the measured pull-out force is inaccurate. Utility Model Content

Specifically, the first fixing component includes a base, a fixing wheel 21 having a fixing surface 211, and a first fixing structure for fixing the fixing wheel 21 on the base and adjusting the angle of the fixing surface 211. The fixing surface 211 is provided with a placement hole 212 for placing the male end and a fixing hole 213 for fixing the male end; Figure 8 , 9 As shown, the second fixing assembly includes two first clamps 3 and a second fixing structure for detachably connecting the two first clamps, one end of the first clamp is a clamped end and the other end is provided with a first clamping groove 32 for clamping the female end, and a first limiting structure 33 is provided in the first clamping groove 32.

[0038] The two first clamps 3 can be fixedly connected by bolts, and a fixing hole is provided on each of the two first clamps 3 .

[0039] by Fig.10 Take the male and female ends shown in the figure as an example. After the male and female ends are connected, the structure is as follows Fig.10 As shown. The male end is provided with a fixing ear 41, and the fixing ear 41 is provided with a fixing hole. Different types of male ends have different angles of the ends on both sides. The top of the female end is provided with a limiting piece 51 placed in the first clamping groove 32.

[0040] By using the above-mentioned tooling, when performing a pull-out force test, after the male end 4 and the female end 5 are plugged in, the male end 4 is partially placed in the placement hole 212, and the fixing ear 41 of the male end 4 is fitted with the fixing surface 211 and fixed in the fixing hole 213 by bolts, and then the first fixing structure is adjusted to make the axes of the male end 4 and the female end 5 vertical; the first clamping groove 32 of the second fixing component clamps the limiting plate 51, and the first limiting structure 33 is placed in the first groove below the limiting plate 51 to achieve mobile locking in the axial direction; in the entire structure, the male end 4 is fixed on the fixing wheel 21, and the first clamp is used to clamp the female end, and the first clamp, the male end 4 and the female end 5 are pulled synchronously, and the test accuracy is high.

[0041] When conducting the insertion force test, the male end 4 and the female end 5 are fixed on the fixing wheel 21 and the second fixing component respectively. Since the fixing surface 211 on the fixing wheel 21 is adjustable, the verticality of the male end 4 can be adjusted, thereby ensuring the vertical centering of the male end 4 and the female end 5 during the test and improving the test accuracy.

[0042] The angle of the fixing surface 211 on the fixing wheel 21 is adjustable, and by adjusting the angle, the testing requirements of male terminals of different models can be met.

[0043] There are many ways to implement the base, the fixing wheel 21 and the first fixing structure in the first fixing assembly.

[0044] For ease of operation, the first fixing structure includes a fixing plate 221 disposed at the end of the fixing wheel 21 and fixed to the base, and a first bolt 222 connecting the fixing plate 221 and the fixing wheel 21. In order to further improve the stability of the fixing of the fixing wheel 21, there are two first fixing structures disposed at both ends of the fixing wheel 21, and the first bolts 222 of the two first fixing structures are coaxially arranged.

[0045] The fixed wheel 21 can be a square column, a triangular column, a cylinder or other structures. In order to improve the stability of the fixed wheel 21, it is preferably a cylinder. In this case, a cross section is provided on the side of the cylinder to form a fixing surface 211. Correspondingly, an arc groove 111 is provided on the base to fit with the fixed wheel 21. The arc groove 111 fits with the fixed wheel 21, which is convenient for adjusting the angle of the fixing surface 211 and also supports the fixed wheel 21.

[0046] The base can be a conventional base, that is, a base with an integrated structure. In order to be compatible with and meet the testing requirements of male terminals of different models, the base includes a face plate 11 and a chassis 12 threadedly connected to the face plate 11. The chassis 12 is fixed, and since the two are threadedly connected, the face plate 11 can be rotated to drive the male terminal to rotate to meet the testing requirements.

[0047] Specifically, refer to Figure 2 , the upper end of the chassis 12 is a tube structure with internal threads, the bottom end of the face plate 11 is a column structure with external threads, and the column structure is adapted to the tube structure. Alternatively, the following structure can be adopted: the bottom end of the face plate 11 is a tube structure with internal threads, the upper end of the chassis 12 is a column structure with external threads, and the column structure is adapted to the tube structure. In this case, the fixing plate 221 can be fixed to the top of the face plate 11.

[0048] In order to facilitate the coaxiality of the female and male ends during test installation, Figure 8 , 9 As shown, the clamped end of the first clamp is provided with a second clamping groove 34 , and the end of the second clamping groove 34 is provided with a second limiting structure 35 .

[0049] The clamp assembly includes a limit sleeve 61, two second clamps 62 for clamping the clamped ends of the first clamp, and a distance adjustment structure for controlling the distance between the two second clamps 62; the control component is used to control the movement of the distance adjustment structure. The limit sleeve 61, the second clamp 62, the distance adjustment structure and the control component of the clamp assembly can all be implemented using existing technologies.

[0050] For ease of operation, Figure 4 , 5 As shown, the limiting sleeve 61 is provided with a limiting groove 614 for limiting the movement of the second clamp 62, and the limiting groove is provided with a first moving guide hole 611, a second moving guide hole 612 and a third moving guide hole 613 in sequence, and the distance between the first moving guide hole 611 and the third moving guide hole 613 gradually increases from top to bottom. The first moving guide hole 611 and the third moving guide hole 613 are in an inverted eight-shaped shape, and the second moving guide hole 612 is placed in the middle of the first moving guide hole 611 and the third moving guide hole 613, and is arranged vertically. The two second clamps 62 are provided with first protrusions 621 respectively placed in the first moving guide hole 611 and the third moving guide hole 613, and the facing surfaces of the two second clamps 62 are provided with second grooves 622.

[0051] The distance adjustment structure includes an adjustment plate 631, an adjustment rod 632, an operating rod 633, and a state locking structure. The adjustment plate 631 is placed in the second grooves 622 of the two second clamps 62 at the same time, the adjustment rod 632 is connected to the adjustment plate 631 and placed between the two second clamps 62, and a second protrusion 6321 is provided on the adjustment rod 632. The operating rod 633 is rotatably arranged on the limit sleeve 61, and an adjustment hole 6331 is provided on the operating rod 633. The second protrusion 6321 is simultaneously placed in the second moving guide hole 612 and the adjustment hole 6331, so that the operating rod 633 rotates to drive the adjustment plate 631 and the adjustment rod 632 to move up and down, thereby controlling the second clamp 62 to clamp the clamped end of the first clamp or the second clamp 62 to release the clamped end of the first clamp. The state locking structure is used to lock the state of the adjustment rod 632 when the second clamp 62 clamps the clamped end of the first clamp.

[0052] There are many ways to implement the state locking structure. For details, please refer to Figure 6 In the structure shown, the state locking structure includes an adjustment cylinder 641 and a spring 642. The adjustment cylinder 641 is provided with a first hole section and a second hole section whose hole diameter is larger than the first hole section from top to bottom, and a step structure is formed between the first hole section and the second hole section. The adjustment rod 632 is provided with a stop ring 6322 placed in the second hole section, and the spring 642 is sleeved on the adjustment rod 632 and placed between the stop ring 6322 and the step structure formed by the first hole section and the second hole section.

[0053] With the above structure, under natural conditions, Figure 7 As shown in a and b, under the push of the spring, the limit ring 6322 abuts against the bottom of the second hole section of the adjustment tube 641, and the first protrusions 621 of the two second clamps 62 are respectively placed at the bottom of the first movable guide hole 611 and the third movable guide hole 613, and the two second clamps 62 are in a tightened state.

[0054] When the second clamp 62 needs to clamp the clamped end of the first clamp, it moves upward. Figure 7 The operating rod 633 is rotated in the direction of the arrow in a. At this time, the operating rod 633 drives the second protrusion 6321 and the adjustment rod 632 to move upward along the second moving guide hole 612, and the spring is compressed. Figure 7 As shown in c and d, there is a gap between the two second clamps 62. At this time, the clamped end of the first clamp is placed in the gap, and the operating rod 633 is released. Under the action of the spring, the limit ring 6322 is pushed downward, and then the adjusting rod 632, the second protrusion 6321, and the adjusting plate 631 move downward, driving the two second clamps 62 to move downward to clamp the clamped end of the first clamp.

[0055] During the clamping process, the second limiting structure 35 is brought into contact with the end of the second clamp 62 .

[0056] When you need to loosen the clamped end of the first clamp, follow Figure 7 Just rotate the operating lever 633 in the manner a.

[0057] In order to facilitate movement on the XY plane to meet different test requirements, a screw 65 is fixed on the top of the state locking structure; it also includes a fixing seat 66, and a bar hole 661 is provided on the fixing seat 66 for fixing the screw 65.
