However, in actual use, the detection port of the wire harness detection fixture is easily exposed to dust or damaged due to accidents when not in use, which affects the service life of the detection fixture. Utility Model Content
[0005] The utility model aims to provide a vehicle gearbox wiring harness continuity test fixture to solve the problem in the background art that the detection port is easily exposed to dust or damaged by accident when not in use, thus shortening the service life of the detection fixture.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a test fixture for conducting the wiring harness of an automobile gearbox, comprising a test fixture body and test ports on both sides of one end of the test fixture body, wherein a test needle seat is fixedly connected inside the test port, an indicator light is fixedly connected at the middle position of one end of the test fixture body, and a display screen is fixedly connected at the middle position of the top of the test fixture body;
[0007] A connecting plate is provided at the upper and lower ends of one end of the test fixture body at one end of the detection port, and a protective mechanism is provided at one end of the connecting plate, and the protective mechanism is used to shield and protect the detection port and the detection needle seat to prevent dust from entering the detection port and the detection needle seat and causing damage;
[0008] The bottom end of the test fixture body is slidably connected with an anti-skid block, and the bottom end of the anti-skid block is provided with an anti-skid mechanism, which is used to increase the friction between the anti-skid block and the table surface, and the top end of the anti-skid block is provided with a reset mechanism, which is used to assist in resetting the position of the test fixture body to increase its applicability during use.
[0009] Furthermore, the protection mechanism includes a mounting box, and the mounting box is fixedly connected to one side of the connecting plate, the interior of the mounting box is fixedly connected to a movable plate via a connecting spring, and a protection plate is provided at the bottom end of the movable plate.
[0010] Furthermore, one side of the protective plate is arc-shaped, and the bottom ends of the protective plates are fitted together.
[0011] Furthermore, the movable plate and the installation box are slidably connected, and the movable plate and the connecting spring are elastic structures.
[0012] Furthermore, the anti-skid mechanism includes anti-skid bumps, and the anti-skid bumps are fixedly connected to one side of the anti-skid plate, and the anti-skid bumps are evenly distributed on one side of the anti-skid plate.
[0013] Furthermore, the reset mechanism includes a slide groove, and the slide groove is opened on both sides of the bottom end of the test fixture body, the top of the anti-slide plate is fixedly connected with a slider matching the slide groove, and a sliding structure is formed between the test fixture body and the anti-slide plate through the slide groove and the slider, and reset springs are fixedly connected on both sides of the slider.
[0014] Furthermore, one side of the return spring is connected to the inner side of the slide slot, and an elastic structure is formed between the return spring and the slide slot.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. When the wire harness is inserted, the two ends of the wire harness will squeeze the protective plate toward the two ends, so that the protective plate moves toward the inside of the installation box. At the same time, the connecting spring is stressed and shortened, and the movable plate slides inside the installation box, so that the protective plate can move more smoothly. When not in use, the installation box and the protective plate can shield the detection port and the detection needle holder to avoid damage caused by impact when the detection port and the detection needle holder are not in use. The protective plate can effectively shield and protect them. At the same time, the protective plate can reduce the dust from entering the detection port, thereby extending the applicability of the detection port when in use;
[0017] Furthermore, the arc shape of the protective plate can assist the wire end in aligning its position when inserting the wire end, and can also facilitate the wire end to squeeze the protective plate toward both ends, thereby increasing the accuracy of insertion. The end surface of the other end of the protective plate can play a stable shielding role, thereby increasing the overall applicability during use.
[0018] Furthermore, the elastic force of the connecting spring can flexibly assist the resetting of the movable plate and the protective plate, so that the movable plate and the protective plate can restore their positions after being squeezed, and at the same time, the bottom ends of the protective plates squeeze each other, thereby achieving a better shielding effect;
[0019] 2. When the test fixture body is hit, the anti-slip plate and anti-slip bumps contact the work surface and play an anti-slip role, so that the test fixture body changes its position on the surface of the anti-slip plate through the slide groove and the slider, so that the test fixture body will not fall even if the position changes, which is stable and anti-slip, avoiding damage caused by accidental collision and falling of the device, and increasing the stability of the test fixture body when in use;
[0020] Furthermore, after the test fixture body is impacted and shifted in position, the elastic force of the reset spring can assist in resetting the position of the test fixture body, so that the test fixture body slides on the surface of the anti-slip plate through the slide groove and the slider and consumes the elastic force. The anti-slip mechanism allows the test fixture body to use its own weight to exert a certain pressure on the anti-slip protrusion even when it is shaking, thereby effectively avoiding positional deviation of the test fixture body when consuming the elastic force.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Embodiment 1: Figure 1-Figure 4 The technical solution shown is to solve the problem: the automobile gearbox wiring harness conduction test fixture discloses a protection mechanism, including a test fixture body 1 and a detection port 2 on both sides of one end of the test fixture body 1, and a detection needle seat 15 is fixedly connected inside the detection port 2, an indicator light 3 is fixedly connected at the middle position of one end of the test fixture body 1, and a display screen 14 is fixedly connected at the middle position of the top of the test fixture body 1;
[0030] A connecting plate 4 is provided at the upper and lower ends of the test fixture body 1 at one end of the detection port 2, and a protective mechanism is provided at one end of the connecting plate 4, which is used to shield and protect the detection port 2 and the detection needle seat 15 to prevent dust from entering the detection port 2 and the detection needle seat 15 and causing damage;
[0031] The bottom end of the test fixture body 1 is slidably connected with an anti-skid protrusion 10, and the bottom end of the anti-skid protrusion 10 is provided with an anti-skid mechanism, which is used to increase the friction between the anti-skid protrusion 10 and the table surface, and the top end of the anti-skid protrusion 10 is provided with a reset mechanism, which is used to assist in resetting the position of the test fixture body 1 to increase its applicability during use.
[0032] The protection mechanism includes a mounting box 5 , and the mounting box 5 is fixedly connected to one side of the connecting plate 4 . The interior of the mounting box 5 is fixedly connected to a movable plate 7 via a connecting spring 6 , and a protection plate 8 is provided at the bottom end of the movable plate 7 .
[0033] One side of the protection plate 8 is arc-shaped, and the bottom ends of the protection plates 8 fit together.
[0034] The movable plate 7 and the installation box 5 are connected in a sliding manner, and the movable plate 7 and the connecting spring 6 are in an elastic structure.
[0035] In this example, by inserting the two ends of the wire harness into the interior of the detection port 2, the detection needle seat 15 and the harness are engaged, thereby playing a detection role. The indicator light 3 can be used to determine whether the harness circuit is unobstructed during detection. Different data can also be displayed through the display screen 14, thereby obtaining different data of the wire harness. When the wire harness is inserted, the two ends of the wire harness will squeeze the protective plate 8 toward both ends, so that the protective plate 8 moves toward the interior of the installation box 5. At the same time, the connecting spring 6 is stressed and shortened in length, and the movable plate 7 slides inside the installation box 5, so that the protective plate 8 can move more smoothly. When not in use, the installation box 5 and the protective plate 8 can be used to shield the detection port 2 and the detection needle seat 15 to avoid damage to the detection port 2 and the detection needle seat 15 when they are not in use. The protective plate 8 can effectively provide shielding protection. At the same time, the protective plate 8 can reduce the entry of dust into the interior of the detection port 2, thereby extending the applicability of the detection port 2 when in use.
[0036] Embodiment 2: Figure 5 and Figure 6 The technical solution shown is to solve the problem: the automobile gearbox wiring harness conductivity test fixture discloses an anti-skid mechanism, which includes an anti-skid protrusion 10, and the anti-skid protrusion 10 is fixedly connected to one side of the anti-skid plate 9, and the anti-skid protrusions 10 are evenly distributed on one side of the anti-skid plate 9.
[0037] In this example, when the test fixture body 1 is hit, the anti-slip plate 9 and the anti-slip protrusion 10 contact the work surface and play an anti-slip role, so that the test fixture body 1 changes its position on the surface of the anti-slip plate 9 through the slide groove 11 and the slider 12, so that the test fixture body 1 will not fall even if the position changes, and it is stable and anti-slip, avoiding damage to the device caused by falling due to accidental collision, and increasing the stability of the test fixture body 1 when in use.
[0038] Embodiment 3: Figure 5 and Figure 6 The technical solution shown is to solve the problem: the automobile gearbox wiring harness conduction test fixture discloses a reset mechanism, which includes a slide groove 11, and the slide groove 11 is opened on both sides of the bottom end of the test fixture body 1, and the top of the anti-skid plate 9 is fixedly connected with a slider 12 matching the slide groove 11, and the slide groove 11 and the slider 12 form a sliding structure between the test fixture body 1 and the anti-skid plate 9, and reset springs 13 are fixedly connected on both sides of the slider 12.
[0039] One side of the return spring 13 is connected to the inner side of the slide slot 11 , and an elastic structure is formed between the return spring 13 and the slide slot 11 .
[0040] In this example, after the test fixture body 1 is impacted and shifted in position, the elastic force of the reset spring 13 can assist in resetting the position of the test fixture body 1, so that the test fixture body 1 slides on the surface of the anti-slip plate 9 through the slide groove 11 and the slider 12 and consumes the elastic force. The anti-slip mechanism allows the test fixture body 1 to use its own weight to apply a certain pressure to the anti-slip protrusion 10 even when it is shaking, thereby effectively avoiding the test fixture body 1 from shifting in position when the elastic force is consumed.
