[0002] A wire harness connector is a connection device used in electrical systems. It can safely and reliably connect wires and cables to ensure the stable transmission of current or signals. It is usually composed of metal contacts and insulators. Wire harness connectors are widely used in automotive, industrial, consumer electronics and other fields. They provide convenient plug-in and unplug operations and have dustproof, waterproof and other protective functions to adapt to various environmental conditions.

[0003] Electric vehicle wiring harness connectors are a type of wiring harness connector, and wiring harness connectors need to be tested before packaging. The problem with the above technology is that the existing wiring harness connector testing device needs to test different wiring harness connectors multiple times in a row. After long-term use, the testing device will generate high temperature and affect the test results. In addition, most of the existing testing devices only dissipate heat through heat dissipation holes, and the effect is relatively general. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides a testing device and a testing method for an electric vehicle wiring harness connector that can overcome the above problems or at least partially solve the above problems.

[0005] The present invention is achieved by providing a testing device and method for an electric vehicle wiring harness connector, comprising a test cabinet, heat dissipation holes being provided on both sides of the test cabinet, a control panel being installed on the front side of the test cabinet, a connection port being provided on the front side of the control panel, a heat dissipation component being provided on the right side of the test cabinet, a cleaning component being provided on one side of the heat dissipation component for use in conjunction with the heat dissipation holes, and a limit assembly being provided on one side of the connection port; The heat dissipation component is used to dissipate heat inside the test cabinet; The cleaning component is used to clean the heat dissipation holes; The limiting component is used to limit the connector interface.

[0006] Preferably, in the present invention, the heat dissipation assembly includes a gas conveyor, both ends of the gas conveyor are connected to connecting pipes, and one side of the connecting pipe is fixedly connected to a conveying bin.

[0007] Preferably, the cleaning assembly includes a motor base, a transmission motor is installed on one side of the motor base, the output ends on both sides of the transmission motor are connected to threaded rods, one side of the threaded rod extends to the inner cavity of the conveying bin and is movably connected to a rotating block, the surface of the threaded rod is sleeved with a threaded block, and one side of the threaded block is fixedly connected to a scraper.

[0008] Preferably, in the present invention, the limiting assembly includes a support plate, an inner cavity of the support plate is provided with a limiting rod, one side of the limiting rod is fixedly connected to a fixing block, and one side of the fixing block is fixedly connected to a tension spring.

[0009] Preferably, in the present invention, there are multiple connection ports, which are evenly distributed on the front side of the control panel.

[0010] Preferably, in the present invention, one side of the delivery bin is fixedly connected to the surface of the test cabinet, and the delivery bin is butted against the heat dissipation hole on the right side of the test cabinet.

[0011] Preferably, in the present invention, one side of the motor seat is fixedly connected to the test cabinet, the threaded rod is connected to the threaded block via a thread, the rotating block is movably connected to the inner wall of the conveying bin via a rotating shaft, and one side of the scraper contacts the test cabinet.

[0012] Preferably, in the present invention, the surface of the limiting rod contacts the inner wall of the support plate, and one end of the tension spring is fixedly connected to the support plate.

[0013] The present invention preferably includes: S1. Pull the limit rod, which drives the fixed block to move. The limit rod slides in the inner cavity of the support plate, and the fixed block stretches the tension spring. Then, insert the connector into the connection port, release the limit rod, and the force released by the stretched tension spring drives the limit rod to reset. The limit rod and the support plate cooperate to clamp the connector, thereby assisting in limiting the position. S2. Long-term testing will cause high temperatures inside the test cabinet, so the gas conveyor needs to be started. The gas conveyor conveys air to the inner cavity of the conveying chamber through the connecting pipe, and then conveys the gas into the test cabinet through the heat dissipation holes on the right. The hot air is discharged through the heat dissipation holes on the left, thereby accelerating the air circulation speed and reducing the temperature; S3. In order to prevent the heat dissipation holes from being blocked, the heat dissipation holes on the right are more likely to be blocked, while the heat dissipation holes on the left are less likely to be blocked, because most of the dust blocking the heat dissipation holes is accumulated during transportation. Start the transmission motor, and the transmission motor drives the threaded rod to rotate. The external thread on the threaded rod and the internal thread in the thread block can control the movement of the thread block. The thread block drives the scraper to scrape back and forth to prevent the heat dissipation holes from being blocked.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention sets a heat dissipation component, a heat dissipation hole and a test cabinet for use. Long-term testing will cause high temperature inside the test cabinet, so it is necessary to start a gas conveyor. The gas conveyor conveys air to the inner cavity of the conveying bin through a connecting pipe, and then conveys the gas into the test cabinet through the heat dissipation hole on the right. The hot air is discharged through the heat dissipation hole on the left, thereby accelerating the air circulation speed and cooling down. This solves the problem that the existing wiring harness connector test device needs to test different wiring harness connectors multiple times in succession. After long-term use, the test device will generate high temperature and affect the test results. In addition, most of the existing test devices only dissipate heat through the heat dissipation holes, and the effect is relatively general. BRIEF DESCRIPTION OF THE DRAWINGS
