[0030] In order to facilitate the placement of the wiring harness into the slot, the upper portion of the slot on each clamping block 5 is provided with an oblique angle.

[0031] In order to increase the friction with the integrated wiring harness, the two clamping plates 10 are provided with a plurality of grooves on the facing sides.

[0032] The power unit 1 includes an electric slide rail 6 and an electric slider 7; the right side of the frame 1 is bolted with the electric slide rail 6; the electric slider 7 is slidably connected inside the electric slide rail 6; the electric slider 7 is fixedly connected to the mounting frame 8.

[0033] The power unit 2 includes an electric slide rail 21 and an electric slider 22; the left part of the frame 1 is bolted with the electric slide rail 21; the electric slider 22 is slidably connected inside the electric slide rail 21; the electric slider 22 is fixedly connected to the mounting plate 1 2.

[0034] The vibration unit includes a mounting plate 2 31, a straight spring 1 32, a mounting plate 33, a vibration motor 34, a magnet block 35, a mounting plate 4 36 and a magnet plate 37; the mounting plate 2 31 is welded to the right side of the mounting plate 1 2; four straight springs 1 32 are fixedly connected to the mounting plate 2 31; the upper ends of all the straight springs 1 32 are commonly fixedly connected to the mounting plate 3 33; the vibration motor 34 is fixedly connected to the middle part of the lower side of the mounting plate 3 33; a magnet block 35 is respectively fixedly connected to the upper front and upper rear of the mounting plate 3 33; each magnet block 35 is magnetically attracted to a magnet plate 37; the two magnet plates 37 are commonly fixedly connected to the mounting plate 4 36.

[0035] It also includes a mounting block 11 and an L-shaped pressing plate 12; each mounting block 13 is welded with a mounting block 11; each mounting block 11 is rotatably connected with an L-shaped pressing plate 12, and each L-shaped pressing plate 12 is fixed with an elastic rubber sheet at the front and rear ends.

[0036] It also includes a mounting plate 5 38 and a limiting rod 39; a mounting plate 5 38 is welded to the right side of each clamping block 5; and two limiting rods 39 are welded to each mounting plate 5 38.

[0037] A plurality of friction rings are fixedly connected to each limiting rod 39 at equal distances.

[0038] The first step: connect the electric slide rail 1 6, the electric push rod 9 and the electric slide rail 2 21 to an external power source, and manually use a wire stripper to strip the end position of the integrated wiring harness so that each wiring harness in the integrated wiring harness has sufficient space for movement, and then place the integrated wiring harness in the middle of the mounting frame 1 8, control the two electric push rods 9 to drive the two clamping plates 10 to move toward each other to clamp the wiring harness, and then clamp the terminals of each wiring harness in the slots of a clamping block 5 respectively, and then manually bend the L-shaped pressing plate 12 downward so that the end of the L-shaped pressing plate 12 is inserted into the slot of the clamping block 5, and the rubber sheet at the end of the L-shaped pressing plate 12 is deformed under pressure, and the elasticity of the rubber sheet makes the end of the L-shaped pressing plate 12 clamped in the slot of the clamping block 5, so that the L-shaped pressing plate 12 blocks the top of the wiring harness terminal, and clamps the wiring harness through the clamping block 5 and the L-shaped pressing plate 12 to prevent the wiring harness terminal from slipping out of the slot. In the left and right directions, the frontmost clamping block 5 and the integrated wiring harness are in a straight line, as shown in FIG. Figure 4 shown.

[0039] Step 2: Control the electric slide rail 16 to drive the electric slider 17, the mounting frame 18, the electric push rod 9 and the clamping plate 10 to move to the right. The two clamping plates 10 move the clamped integrated wiring harness to the right. The front wiring harness is gradually straightened, and then the wiring harness terminal is pulled. The wiring harness terminal is stuck in the slot on the clamping block 5, and the clamping block 5 is connected to the pressure sensor 4. In this way, the pressure sensor 4 can detect the tension data of the wiring harness terminal and the wiring harness. When the tension suddenly decreases, it means that the wiring harness is separated from the terminal. In this way, the tension change between the wiring harness and the terminal is detected by the pressure sensor 4; then, immediately control the electric slide rail 21 to drive the electric slider 22 and the mounting plate 2, The mounting block 3, the pressure sensor 4 and the clamping block 5 are moved forward so that in the left-right direction, the second clamping block 5 and the integrated wiring harness are in a straight line, and the integrated wiring harness is continuously controlled to move to the right so that the second wiring harness pulls its terminal, and the pressure sensor 4 also detects the change in tension between the wiring harness and the terminal; and so on, so that the tension of all wiring harness terminals is detected; in this way, the tension detection of each wiring harness and its terminal in the integrated wiring harness is completed continuously without frequent manual operation, thereby improving efficiency; moreover, when pulling each wiring harness terminal, the wiring harness and the terminal are kept in the same straight line, so that the wiring harness pulls the terminal straightly, thereby ensuring the accuracy of the detection result.

[0040] When designing and manufacturing automotive wiring harnesses, the crimping technology is used to connect the wiring harness and the terminal together, and then these terminals are inserted into the connector, and then the connector is plugged into various electrical devices so that the various electrical devices of the car can establish electrical connections. The wiring harness is usually fixed to the body or frame by clips, cable ties or buckles to reduce movement during vehicle movement. If the fixings are not designed properly or become loose during use, when the car vibrates up and down due to road bumps, the wiring harness and the terminal may still produce relative movement in the up and down directions during the bumps. This up and down relative movement will cause the crimping point between the wiring harness and the terminal to gradually loosen, reducing the connection strength. In order to detect the effect of up and down vibration on the connection strength of the wiring harness and the terminal, after the terminals of each wiring harness are respectively clamped in the slots of a clamping block 5, the outer sheath of the integrated wiring harness is located on the right side of the mounting plate three 33, and the mounting plate four 36 and the magnet plate 37 are manually buckled on the mounting plate three 3 3, the magnet block 35 and the magnet plate 37 are adsorbed together, so that the wiring harness is clamped by the mounting plate four 36 and the mounting plate three 33, and then the vibration motor 34 is energized. The vibration motor 34 drives the mounting plate three 33, the mounting plate four 36 and the clamped wiring harness to vibrate up and down. During the vibration, the mounting plate three 33 reciprocates to compress the straight spring one 32, and the wiring harness terminal is restricted by the L-shaped pressure plate 12 in the card slot of the card block 5, so that the wiring harness and the terminal produce relative movement in the up and down directions, simulating the scene of vibration caused by bumps on the road during the driving of the car. After the vibration test, the mounting plate four 36 and the magnet plate 37 are manually lifted and separated from the magnet block 35, and then the second step of the operation in Example 1 is performed to detect the tension between each wiring harness and its terminal in the integrated wiring harness, and the test results are compared with the test results without the vibration test to obtain the influence of vibration on the connection strength of the wiring harness and the terminal.

[0041] When conducting a vibration test, only the frontmost wiring harness and terminal remain straight, and the rest of the wiring harnesses and their terminals are in a skewed state. In the skewed state, the connection between the wiring harness and the terminal will be subjected to uneven mechanical stress, causing the connection point to relax or fatigue more quickly during the vibration process, which does not truly simulate the vibration mode of the vehicle during driving. In actual use, the wiring harness and the terminal always remain straight, resulting in inaccurate test results; therefore, two pairs of limit rods 39 are provided on the right side of each clamping block 5. When the terminals of each wiring harness are respectively clamped in the slots of a clamping block 5, the part of the wiring harness close to the terminal is placed between the two pairs of limit rods 39. In this way, during the vibration test, each wiring harness and terminal are kept straight, truly simulating the vibration mode of the vehicle during driving and ensuring the accuracy of the test results.

[0042] In addition, a number of friction rings are fixedly connected to each limit rod 39 at equal distances. When the vibration motor 34 drives the mounting plate three 33, the mounting plate four 36 and the clamped wiring harness to vibrate up and down, the wiring harness rubs against the friction ring. After the friction is completed, it can be observed whether there is wear at the friction point of the wiring harness, thereby detecting the friction resistance of the wiring harness.

[0043] Example 2

[0044] On the basis of Example 1, Figure 5-Figure 8 As shown, it also includes a transmission shaft 41, a mounting block 3 42, a connecting rod 43, a straight spring 2 44, a clamp 2 45, a spring telescopic rod 46, a mounting frame 2 47, a trapezoidal block 48, a pressure rod 49 and a power unit 3; each mounting block 2 11 is rotatably connected to a transmission shaft 41; each right part of the transmission shaft 41 is fixedly connected to a mounting block 3 42; each mounting block 3 42 is penetrated by a connecting rod 43; each connecting rod 43 is slidably connected to a clamp 2 45; each clamp 2 45 is fixedly connected to the mounting block 3 42 A straight spring 44; two spring telescopic rods 46 are fixedly connected to each mounting block 3; a mounting frame 47 is fixedly connected to the telescopic end of each spring telescopic rod 46; a trapezoidal block 48 is fixedly connected to the lower part of all mounting frames 47 on the same mounting block; the trapezoidal block 48 is located between two clamping plates 45; a pressure rod 49 is welded to the lower side of each L-shaped pressure plate 12; each pressure rod 49 cooperates with a mounting frame 47; a power unit 3 is connected to the mounting plate 2; the left part of each transmission shaft 41 is connected to the power unit 3.

[0045] The power unit 3 includes a gear 410, a sliding frame 411, a rack 412 and a positioning plate 413; the sliding frame 411 is slidably connected to the mounting plate 2; the rack 412 is fixedly connected to the sliding frame 411; a gear 410 is fixedly connected to the left part of each transmission shaft 41; each gear 410 is meshed with the rack 412; the positioning plate 413 is connected to the rear part of the lower side of the rack 412.

[0046] In order to increase the friction force with the wiring harness terminal, each clamping plate 45 is provided with a plurality of grooves.

[0047] When the connector is plugged into various electrical devices, some connectors will be inserted in a vertical state, that is, the connector drives the wiring harness and the terminal to twist ninety degrees. Therefore, it is also necessary to test the effect of vibration on the connection strength between the wiring harness and the terminal when the connector is inserted into the electrical equipment in a vertical state; therefore, a mechanism for steering the wiring harness terminal is provided. When the end of the L-shaped pressing plate 12 is inserted into the slot of the card block 5, the L-shaped pressing plate 12 presses down the mounting frame 47 and the trapezoidal block 48 through the pressing rod 49, and the mounting frame 47 presses down the spring telescopic rod 46. After the trapezoidal block 48 is pressed down, it is moved away from between the two clamping plates 45. In the initial state, the straight spring 44 is in a stretched state. After there is no limit of the trapezoidal block 48 between the two clamping plates 45, due to the action of the two straight springs 44 The two clamping plates 45 move toward each other to clamp the wiring harness terminal; when performing a vibration simulation test on the connector when it is vertically inserted into the electrical equipment, the sliding frame 411, the rack 412 and the positioning plate 413 are manually pushed forward to make the positioning plate 413 rest against the mounting plate 2. During this process, the rack 412 just drives the gear 410 to rotate ninety degrees, and the gear 410 drives the transmission shaft 41, the mounting block 3 42, the connecting rod 43, the straight spring 2 44, the clamping plate 2 45 and the clamped wiring harness terminal to rotate ninety degrees. Then, when performing the vibration test again, the relative movement direction of the wiring harness and the terminal changes by ninety degrees, thereby testing the influence of vibration on the connection strength between the wiring harness and the terminal when the connector is vertically inserted into the electrical equipment.

[0048] Example 3

[0049] On the basis of Example 2, Figure 5-Figure 6 As shown, it also includes an arc-shaped fixing block 1 51, an arc-shaped fixing block 2 52, a clamping rod 53, an arc-shaped rubber pad 54, a rack 2 55 and a positioning plate 2 56; the arc-shaped fixing block 1 51 is rotatably connected in the mounting plate 4 36; the arc-shaped fixing block 2 52 is rotatably connected in the mounting plate 3 33; a plurality of tooth grooves are evenly spaced on the arc-shaped fixing block 1 51 and the arc-shaped fixing block 2 52; two clamping rods 53 are fixedly connected to the lower side of the arc-shaped fixing block 1 51; all the clamping rods 53 They are all inserted into the arc-shaped fixing block 2 52; the arc-shaped fixing block 2 52 is provided with two slots for the card rod 53 to be inserted; the arc-shaped fixing block 1 51 and the arc-shaped fixing block 2 52 are respectively fixed with an arc-shaped rubber pad 54 on the opposite sides; the mounting plate 4 36 is slidably connected with a rack 2 55; the rack 2 55 is meshed with the arc-shaped fixing block 1 51 and the arc-shaped fixing block 2 52; a positioning plate 2 56 is fixed to the middle part of the rack 2 55; the positioning plate 2 56 is in contact with the mounting plate 4 36.

[0050] The tightness of the outer sheath of the integrated wiring harness and the wiring harness refers to the tightness of the outer sheath wrapped around the wiring harness. A too loose outer sheath leaves gaps, which makes it easy for moisture, dust, oil or other contaminants to invade. These contaminants will corrode the wires or affect the electrical performance of the wiring harness. The loose outer sheath may move or slip during installation, increasing the difficulty of installation. During maintenance and inspection, it may also be difficult to accurately judge the state of the wiring harness due to the instability of the outer sheath. After the terminals of each wiring harness are respectively clamped in the slots of a clamping block 5, the outer sheath of the integrated wiring harness is located on the right side of the mounting plate three 33, and then all the wiring harnesses are gathered on the arc-shaped rubber pad 54 of the arc-shaped fixing block two 52, and then the mounting plate four 36, the magnet plate 37 and the arc-shaped fixing block one 51 are buckled on the magnet block 35 on the mounting plate three 33, and the magnet block 35 and the magnet plate 37 are adsorbed together, so that the clamping rod 53 on the arc-shaped fixing block one 51 is inserted into the arc-shaped fixing block two 52, so that the arc-shaped fixing The fixed block 1 51 and the arc-shaped fixed block 2 52 are locked together to form a complete toothed ring. At the same time, the arc-shaped rubber pad 54 on the arc-shaped fixed block 1 51 and the arc-shaped rubber pad 54 of the arc-shaped fixed block 2 52 clamp the wiring harness tightly together; then, the rack 2 55 is manually pushed forward, and the rack 2 55 drives the arc-shaped fixed block 1 51 and the arc-shaped fixed block 2 52 to form a complete toothed ring for rotation. The arc-shaped fixed block 1 51 and the arc-shaped fixed block 2 52 drive the two arc-shaped rubber pads 54 and all the clamped wiring harnesses to rotate, so that all the wiring harnesses are twisted and close to each other and gathered together, and then observe the tightness between the wiring harness and the outer sheath. If the wiring harness and the outer sheath are still in close contact without a gap or the gap is very small after the wiring harnesses are close to each other and gathered together, it means that the wiring harness and the outer sheath are not too loose and are qualified; when resetting, the rack 2 55 and the positioning plate 2 56 are manually pulled to the right so that the positioning plate 2 56 contacts the mounting plate 4 36 again.
