Therefore, it should not be construed as a limitation to the present utility model.

[0019] The embodiments of the present utility model are as follows Figures 1 to 3As shown in the figure, an installation mechanism for the withstand voltage test of a wire harness includes a frame 1. The frame 1 is used to install the test device at the corresponding work station. At the same time, a withstand voltage tester electrically connected to the connection joint through a wire is provided on the frame 1. A base 2 is provided on the frame 1. The base 1 is a long strip-shaped base, which is arranged in the middle position of the frame 1 and extends in the left-right direction. On the opposite sides of the top surface of the base 1, a first card slot 3 and a second card slot 4 for placing the wire harness 7 with axes parallel to the connection line of the two sides are correspondingly arranged. The wire harness 7 is the wire harness on the automotive fan motor. One end is the power supply end 70 with terminals, and the other end is the motor connection end 71 for connecting to the automotive fan motor. For example, the first card slot 3 is arranged at the front right position of the top surface of the base 2 to place the power supply end 70 of the wire harness 7, and the second card slot 4 is arranged at the front left position of the top surface of the base 2 to place the motor connection end 71 of the wire harness 7. At this time, both the first card slot 3 and the second card slot 4 extend along the left-right direction of the base 2. For the setting structure of the first card slot 3 and the second card slot 4 on the top surface of the base 2, in order to facilitate the taking and placing of the wire harness 7, a first base 20 and a second base 21 are correspondingly arranged on the opposite sides of the top surface of the base 2. The first card slot 3 is arranged on the top surface of the first base 20, and the second card slot 4 is arranged on the top surface of the second base 21. The first base 20 is arranged on the right side of the top surface of the base 2, and the second base 21 is arranged on the left side of the top surface of the base 2. In this way, the first card slot 3 and the second card slot 4 are arranged at a position higher than the top surface of the base 2. After the wire harness 7 is placed in the two card slots, the wire harness 7 is suspended above the base 2, which is convenient for the taking and placing of the wire harness 7. A quick clamp 5 for pressing both ends of the wire harness 7 corresponding to the first card slot 3 and the second card slot 4 is also provided on the base 2. The quick clamp 5 is selected as a horizontal or vertical quick clamp, and its upper pressing head is selected as a rubber pressing head. A quick clamp 5 is arranged at the position corresponding to the first card slot 3 on the base 2. When the first card slot 3 is arranged on the right side of the top surface of the base 2, this quick clamp 5 is also on the right side of the top surface of the base 2, which can be called the right quick clamp 5. This quick clamp 5 is used to position the power supply end 70 placed in the first card slot 3 to prevent it from moving during the connection with the connection joint and affecting the connection. A quick clamp 5 is also arranged at the position corresponding to the second card slot 4. When the second card slot 4 is arranged on the left side of the top surface of the base 2, this quick clamp 5 is on the left side of the top surface of the base 2, which can be called the left quick clamp 5. This quick clamp 5 is used to fix the motor connection end 71 of the wire harness 7, which is convenient for the connection with the connection joint. For example, the two quick clamps 5 are arranged at the rear position adjacent to the first card slot 3 and the second card slot 4 on the top surface of the base 2;On the frame 1, there are also connection joints for corresponding to both ends of the detachable electrical connection harness 7 that move through the moving platform. There are two corresponding connection joints, and they are both detachably connected to the withstand voltage tester through wires. One connection joint is used to electrically connect to the motor connection end 71, and the other connection joint is used to connect to the power supply end 70. Both connection joints are adjusted in position through the moving platform and aligned with the corresponding motor connection end 71 and power supply end 70 for connection.;

[0020] Further improvements, such as Figures 1 to 3As shown in the figure, the first card slot 3 is a card slot adapted to the power supply terminal 70, and the second card slot 4 is a card slot adapted to the motor connection terminal 71. That is to say, the first card slot 70 is for placing the plug connector of the power supply terminal 70. The housing of the plug connector is placed in the first card slot 70, and then the pressing head of the quick clamp 5 on the right presses against the housing of the plug connector to fix it. The first connector 8 is inserted into the housing to achieve electrical connection between the two. The first connector 8 is a connector that matches the terminal and can be detachably and snap-fitted; the second card slot 4 is used to place the motor connection terminal 71; the connection connector includes a first connector 6 that can move horizontally and is adjacent to the first card slot 3 and a second connector 60 that can move up and down and is adjacent to the second card slot 4. The first card slot 3 is arranged on the right side of the top surface of the base 2, and the first connector 6 is arranged on the right side of the base 2. The first connector 6 and the first card slot 3 are at the same height. The first connector 6 can move in the XY axis directions, that is, first move along the Y axis to align the first connector 6 with the first card slot 3, and then move along the X axis to insert the first connector 6 into the housing of the plug connector placed in the first card slot 3 to be electrically connected to the terminal. That is, on the frame 1, a first moving platform 8 that moves on a horizontal plane is arranged at a position adjacent to the first card slot 3. The first connector 6 is arranged on the first moving platform 8 and moves horizontally through the first moving platform 8. The first moving platform 8 can be any existing XY axis moving platform driven by a cylinder; at the same time, since the first connector 6 can move horizontally, multiple first connectors 6 can be arranged. The multiple first connectors 6 have different specifications. That is to say, one first connector 6 corresponds to one type of terminal, which can meet the withstand voltage tests of wire harnesses 7 with different terminals. The multiple first connectors 6 are arranged side by side at intervals on the first moving platform 8, and the first moving platform 8 moves to align different first connectors 6 with the first card slot 3; the second card slot 4 is arranged on the left side of the top surface of the base 2, and the second connector 60 can move to directly above the second card slot 4 and then move down to be electrically connected to the motor connection terminal 71; at this time, the alignment of the first connector 6 and the first card slot 3 can be calculated according to the positions of the first card slot 3 and the first moving platform 8 to obtain the distance that the first connector 6 needs to move, and the first moving platform 8 is used to limit the moving distance of the first connector 6 to achieve their alignment; on the moving platform where the second connector 60 is arranged, a camera that can perform visual positioning and faces the second card slot 4 and moves synchronously with the second connector 60 can be arranged. When the second connector 60 moves horizontally to align with the second card slot 4, the movement of the second connector 60 is stopped, and then the second connector 60 moves down and presses against the motor connection terminal 71.

[0021] Further improvements, such as Figure 1 and Figure 3As shown in the figure, a support base 10 is provided on the frame 1 at a position adjacent to the second card slot 4. A second moving platform 80 that can move on a vertical plane and is located above the second card slot 4 is provided on the support base 10. The second joint 60 is provided on the second moving platform 80 and moves on the vertical plane through the second moving platform 80. That is, when the second card slot 4 is provided on the left side of the top surface of the base 2, the support base is provided on the front left side of the base 2. The second moving platform 80 selects any existing moving platform that can be driven by a cylinder and can move in the YZ axis direction. Then the second moving platform 80 is provided on the upper part of the support base 10 and is located above the second card slot 4. The second joint 60 is provided on the second moving platform 80. It first moves horizontally in the Y-axis direction to directly above the second card slot 4 through the second moving platform 80 and then moves downward to press against the motor connection end 71 of the wire harness 7 in an electrical connection. The second joint 60 is a spring probe that can press against and electrically connect to the motor connection end 71. It uses the spring probe to make electrical connection with the metal wire extending out of the insulating layer of the motor connection end 71. It does not require a complex structure and is easy to use. At this time, the bottom surface of the spring probe has a flat structure, which can better press against the metal wire of the motor connection end 71. The second card slot 4 is a card slot adapted to the motor connection end 71. Since the structure of the motor connection end 71 of the wire harness 7 has multiple parallel wires in the insulating layer, in order to better limit and fix these wires, the second card slot 4 includes a plurality of small card slots arranged in parallel at intervals in the front-back direction on the top surface of the second base 21. One small card slot holds one wire. A support platform 40 for supporting the motor connection end 71 of the wire harness 7 is provided on the top surface of the base 2 at a position adjacent to the second card slot 4 between the first card slot 3 and the second card slot 4. A quick clamp 5 on one side of the second card slot 4 is provided corresponding to the support platform 40, that is, the quick clamp 5 on the left side is provided corresponding to the support platform 40. The support platform 40 and the second card slot 4 are both provided on the left side of the top surface of the base 2, and the support platform 40 is located on the right side of the second card slot 4. In this way, each wire of the motor connection end 71 of the wire harness 7 is correspondingly placed in a different small card slot. The second joint 60 is correspondingly provided with a plurality of contact feet, and each contact angle corresponds to a small card slot. In the small card slot, the contact feet of the second joint 60 press against the metal wire extending out of the insulating layer of the motor connection end 71 of the wire harness 7 to achieve the electrical connection between the second joint 60 and the motor connection end 71 of the wire harness 7; the support platform 40 supports the insulating layer that wraps all the wires of the motor connection end 71 of the wire harness 7. The quick clamp 5 on the left side is provided directly behind the support platform 40. The pressing head of the quick clamp 5 on the left side correspondingly presses against the insulating layer that wraps all the wires of the motor connection end 71 of the wire harness 7 to limit it; an electrical insulating layer is provided in the small card slot of the second card slot 4 to prevent the second base 21 from conducting electricity.
