Detailed Implementation

[0026] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1: As Figures 1-7 As shown, a connector waterproof plug testing fixture for a wire harness includes a base plate 1. Push-pull members and a metal conductive plate 2 are respectively connected to both ends of the base plate 1. A fixed seat 3 and a slide 4 are connected to the base plate 1 between the push-pull members and the metal conductive plate 2. The slide 4 is slidably fitted onto the base plate 1, and a base 5 for accommodating a connector 1302 is connected to the slide 4. A retaining plate 501 is connected above the base 5. Several sliding sleeves 6 are connected to the fixed seat 3. Metal pins 7 are slidably fitted onto the sliding sleeves 6. An elastic element is connected inside the sliding sleeve 6, and the elastic element pushes the metal pins 7 to move away from the metal conductive plate 2. When the push-pull member pushes the slide 4 to move closer to the metal conductive plate 2, the connector 1302 on the base 5 pushes the metal pins 7 to contact the metal conductive plate 2.

[0028] The push-pull component is a push-pull clamp 8, the base of which is connected to the base plate 1; one end of the slide 4 is connected to the support plate 9, and one end of the clamping rod of the push-pull clamp 8 is connected to the support plate 9 by a nut; a linear guide rail 10 is connected to the base plate 1, and the slide 4 is connected to the slider of the linear guide rail 10.

[0029] The base 5 also includes a baffle 502, with side plates 503 connected to both ends of the baffle 502; one end of the clamping plate 501 is connected to one of the side plates 503 by a hinge, and the other end is clamped to the top of the other side plate 503.

[0030] The sliding sleeve 6 is interference-fitted to the fixed base 3, and the elastic element is a spring. One end of the spring is fixed to the inside of the sliding sleeve 6. The metal pin 7 is slidably connected to the inner wall of the sliding sleeve 6, and the other end is fixed to the outer wall of the metal pin 7.

[0031] There are four sliding sleeves 6 arranged in a rectangular array, with each metal pin 7 corresponding to one sliding sleeve 6.

[0032] The metal conductor plate 2 has a notch for the avoidance wire 1301.

[0033] Four supports 11 are connected to the lower surface of the base plate 1.

[0034] The base plate 1, the fixed seat 3, the slide 4, and the base 5 are all made of insulating materials.

[0035] Example 2: This example is a further improvement on Example 1. The main improvement is that in Example 1, one end of the wire harness 13 droops during use, causing the connector 1302 on the base 5 to easily tilt. In this example, the above-mentioned defect can be avoided. Specifically: An insulating support plate 12 is connected to the metal conductive plate 2; in this embodiment, the insulating support plate 12 connected to the metal conductive plate 2 can support the wire harness 13, prevent the connector 1302 on the base 5 from tilting, and ensure the accuracy of the test results.

[0036] Apart from the above, this embodiment is exactly the same as Embodiment 1, and will not be described again here.

[0037] The specific working principle of this utility model is as follows: This utility model is used in conjunction with the wire harness 13 integrated tester. The metal conductive plate 2 is electrically connected to the wire harness integrated tester through wires, and the metal PIN pin 7 is also electrically connected to the wire harness 13 integrated tester through wires.

[0038] During operation, the operator first opens the clamp 501, places the connector 1302 at one end of the wire harness 13 on the base 5, and the other end on the support plate 12. After lowering the clamp 501, the clamp 501 presses down on the connector 1302. The operator then pulls the wrench of the push-pull clamp 8 to move the slide 4. Since the metal pins 7 correspond to the waterproof plugs 1304 on the connector 1302, if all four waterproof plugs 1304 on the connector 1302 are installed in place, the waterproof plugs 1304 will push the corresponding metal pins 7 to contact the metal conductive plate 2. At this time, the display screen of the wire harness 13 integrated tester will show "passed," indicating that the wire harness 13 is a good product. If one of the four waterproof plugs 1304 on the connector 1302 is missing, the corresponding metal pin 7 will extend into the mounting hole 1303 and will not be able to contact the metal conductive plate 2. At this time, the display screen of the wire harness 13 integrated tester will show "failed," indicating that the wire harness 13 is a defective product.

[0039] The wire harness comprehensive tester is a commonly used conductivity testing instrument in the wire harness 13 production field. Its structure and principle will not be described in detail here.

[0040] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
