Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a detection device for an automobile wiring harness connector. Background Art

[0002] The wiring harness connector is a type of terminal, also known as a plug connector, which consists of a plug and a socket. The connector is a relay station for the wiring harness in the automotive circuit. In the process of realizing the utility model, the inventor found that at least the following problems have not been solved in the prior art: in the production process of automotive wiring harnesses, a tensile test is required, and it is difficult to clamp the wiring harness connector. In addition, the clamping device is compressed due to the tensile force, making it difficult to disassemble.

[0003] A Chinese patent with application number CN202020533464.X discloses a detection device for an automotive wiring harness connector, including a detection box and a wiring harness connector, a push rod motor is fixedly installed at the left end of the inner cavity of the detection box, and a support rod is fixedly installed at the right end of the inner cavity of the detection box. The utility model sets the wiring harness connector on the limit rod by setting a limit rod, and then pulls the wiring harness connector by starting the push rod motor, and then the pressure sensor sends data to the PLC controller, and then the PLC controller sends the data to the A / D converter, and then the A / D converter displays the pressure data on the display screen, so that the maximum tension of the wiring harness connector can be accurately measured according to the pressure data on the display screen. When the detection is completed, the push rod motor is started to bring the two fixed blocks closer to each other, and the wiring harness connector only needs to be removed from the limit rod, which further makes disassembly more convenient, more practical, and suitable for wide promotion and use.

[0004] However, the above patent does not fix the wiring harness connector when performing tension testing on the wiring harness connector. When the wiring harness connector is subjected to tension, displacement may occur, resulting in inaccurate test results.

When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0026] like Figures 1 to 6 As shown, the utility model is a detection device for automobile wiring harness connectors, comprising: a detection box 1, a detection mechanism for detecting the wiring harness connector, and a moving mechanism for facilitating the removal and placement of the wiring harness connector;

[0027] The detection mechanism includes: an installation box 2 arranged in the inner cavity of the detection box 1, a clamping component for clamping and fixing the wiring harness connector during detection, and a pulling component for pulling the wiring harness connector to both sides for detection; the clamping component includes: a U-shaped plate 7 symmetrically arranged on the top of the installation box 2, a U-shaped opening opened on one side of the U-shaped plate 7, a linkage rod 10 installed through the center of the top of the U-shaped plate 7, a linkage block 11 fixedly installed on the top of the linkage rod 10, a second clamping plate 9 fixedly installed at the bottom of the inner cavity of the U-shaped plate 7, a linkage spring 13 fixedly installed between the top of the second clamping plate 9 and the top of the inner cavity of the U-shaped plate 7, and by pulling the two linkage blocks 11 upwards, The adjacent linkage rods 10 are driven to move upward through the two linkage blocks 11, and the adjacent second clamping plates 9 are driven to move upward through the two linkage rods 10. The adjacent linkage springs 13 of the two second clamping plates 9 are compressed. At this time, the two ends of the automobile wiring harness connector are respectively placed in the corresponding inner cavities of the first clamping plates 8, and the wiring harness passes through the adjacent U-shaped openings. At this time, by loosening the two linkage blocks 11, the adjacent second clamping plates 9 can be driven to move downward through the elastic force of the linkage springs 13. Through the mutual cooperation of the second clamping plates 9 and the first clamping plates 8, the automobile wiring harness connector can be clamped and fixed, so that the automobile wiring harness connector will not be displaced during the tension detection process, thereby improving the detection accuracy.

[0028] The pulling assembly includes: a double-axis motor 3 fixedly installed at the bottom of the inner cavity of the installation box 2, a threaded rod 4 fixedly installed on the power output shaft of the double-axis motor 3, a threaded block 5 threadedly installed on the outer edge of the threaded rod 4, a guide rod 6 installed through the side wall of the threaded block 5, a rectangular opening symmetrically opened on the top of the installation box 2, the top of the threaded block 5 passes through the inner cavity of the rectangular opening, and is fixedly connected to the bottom of the U-shaped plate 7. By starting the double-axis motor 3, the two threaded rods 4 are driven to rotate at the same time through the power output shaft of the double-axis motor 3. The thread directions of the two threaded rods 4 are opposite, and the rotation directions of the two threaded rods 4 are the same, so the two threaded blocks 5 can be driven to move inward or outward at the same time. When the two threaded rods 4 drive the adjacent threaded blocks 5 to move outward, the threaded blocks 5 drive the adjacent U-shaped plates 7 to move to both sides, thereby driving the wiring harness connector to be pulled to both sides. Since the two ends of the wiring harness connector are pulled synchronously, the force on both ends of the wiring harness connector is uniform, and pressure sensors 14 are respectively provided on the inner walls of the two U-shaped plates 7. The pressures at both ends of the wiring harness connector are sensed and received simultaneously by the two pressure sensors 14, and then the pressure data is displayed on the PLC controller 15 for easy reading by the staff. Through the two sets of pressure data, the maximum pulling force of the wiring harness connector can be measured more accurately.

[0029] The moving mechanism includes: a movable door 19 hingedly installed on one side of the detection box 1, a fixed plate 16 fixedly installed on the side wall of the installation box 2, a movable rod 18 hingedly installed between the movable door 19 and the fixed plate 16, a slider 17 fixedly installed at one end of the fixed plate 16, a limiting groove provided on the inner wall of the detection box 1, the slider 17 is located in the inner cavity of the limiting groove, and a clamping component for facilitating the opening and closing of the movable door 19, the clamping component includes: a mounting groove provided on the movable door 19, a clamping spring 21 symmetrically fixedly installed on the top of the inner cavity of the mounting groove, a clamping plate 22 fixedly installed at the bottom end of the clamping spring 21, a connecting plate 23 fixedly installed on one side of the clamping plate 22, a transverse plate 20 fixedly installed on one side of the detection box 1, the transverse plate 20 is located in the inner cavity of the mounting groove, a clamping groove provided on the top of the transverse plate 20, the bottom of the clamping plate 22 is plugged into the inner cavity of the plug-in groove, a pressure sensor 14 is fixedly installed on the inner wall of the U-shaped plate 7, a PLC controller 15 is fixedly installed on the outer side of the detection box 1, and the pressure sensor 14 is electrically connected to the PLC controller 15. By pulling the connecting plate 23 upward, the connecting plate 23 drives the clamping plate 22 to move upward, and the clamping spring 21 is compressed by the clamping plate 22, so that the clamping plate 22 is separated from the horizontal plate 20. At this time, the movable door 19 can be opened upward, and the two movable rods 18 are driven to move by the movable door 19, and the adjacent fixed plates 16 are pulled to move by the two movable rods 18, and the installation box 2 is driven to move by the two fixed plates 16, so that the installation box 2 is moved to the outside of the detection box 1;

[0030] When the installation box 2 moves to the outside of the detection box 1, the two U-shaped plates 7 are moved closer to each other by starting the dual-axis motor 3. At this time, the linkage block 11 is pulled upward again, and the linkage rod 10 is driven to move upward by the linkage block 11, and the second clamping plate 9 is driven to move upward by the linkage rod 10, so that the second clamping plate 9 and the first clamping plate 8 have no clamping effect on the wiring harness connector. At this time, it is convenient to disassemble the wiring harness connector, and then install the wiring harness connector that needs to be tested. After the wiring harness connector is installed, the installation box 2 can be driven to move to the inner cavity of the detection box 1 by closing the movable door 19;

[0031] It is additionally noted here that by moving the installation box 2, it is convenient for the staff to take and place the wiring harness connector. A visual window is provided on the movable door 19. During the detection process, the movable door 19 is in a closed state, and the staff can clearly observe the detection status of the wiring harness connector through the visual window, thereby effectively preventing the wiring harness connector from breaking during detection and causing harm to the staff.

[0032] A slide bar 12 is symmetrically fixedly installed at the bottom of the installation box 2, and a slide groove is symmetrically opened at the bottom of the inner cavity of the detection box 1. The slide bar 12 is located in the inner cavity of the slide groove. The slide bar 12 slides in the inner cavity of the slide groove, thereby limiting the installation box 2, so that the installation box 2 is more stable when moving.

[0033] Working principle: When in use, the automobile wiring harness connector is first clamped and fixed by the clamping component. After the wiring harness connector is fixed, the wiring harness connector is subjected to tension test by pulling the component. When the test is completed, the wiring harness connector can be easily moved to the outside of the test box 1 through the moving mechanism, so as to facilitate the removal and placement of the wiring harness connector.

[0034] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
