Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a conduction detection platform. Background Art

[0002] The wire harness continuity test bench is mainly used to detect open circuits, short circuits, and misalignments in the wire harness, as well as the presence and position of the secondary lock of the sheath's airtightness, and the function of airbag parts. It can also test accessories such as resistors and diodes on the line. It is mainly used in automotive wire harness testing, aircraft control systems, motor vehicle control systems, and refrigerators and washing machines in the home appliance industry.

[0003] When conducting a continuity test on the wiring harness, the wiring harness must first be fixed to prevent it from falling or becoming loose during the continuity test, which may cause a deviation in the test result or a failure in the test. However, the conventional line speed plug is connected to the test bench mainly in the form of plug insertion, which is prone to loosening. Therefore, we propose a continuity test bench to solve the above-mentioned problems. Utility Model Content

[0006] A conduction test bench includes a workbench, a wiring harness tester is fixedly installed on the top of the workbench, and a positive wire and a negative wire are electrically connected to the wiring harness tester, respectively. The test bench also includes:

[0007] Two supporting mechanisms, both of which are installed on the top of the workbench, and joints are installed on the top of the supporting mechanisms;

[0008] The positioning mechanism is connected to the two supporting mechanisms respectively, and the positioning mechanism is connected to the top of the workbench.

[0009] In a possible design, the support mechanism includes a support column fixedly mounted on the top of the workbench, the top of the support column is fixedly connected to the corresponding joint, a reset component is mounted on the support column, and the reset component is connected to the positioning mechanism.

[0010] In a possible design, the reset assembly includes a movable ring slidably mounted on a support column, a connecting rod is fixedly installed on one side of the top of the movable ring, the top of the connecting rod is connected to the positioning mechanism, and a tension spring located above the movable ring is mounted on the support column, and the top and bottom ends of the tension spring are fixedly connected to the bottom of the joint and the top of the movable ring respectively.

[0011] In a possible design, both ends of the wiring harness are fixedly connected with plugs, the plugs are electrically plugged into one side of the corresponding connector, and the plugs are clamped with the positioning mechanism.

[0012] In one possible design, the positioning mechanism includes a baffle fixedly mounted on the top of the connecting rod, the baffle contacts one side of the plug corresponding to the wiring harness to be tested, a U-shaped bracket is symmetrically fixedly mounted on one side of the baffle, the plug of the wiring harness to be tested is clamped on the U-shaped bracket, connecting components are installed on the top of both sides of the U-shaped bracket, the same pressure plate is installed on the top of the two connecting components, the pressure plate is used to position and clamp the plug of the wiring harness to be tested, the bottom ends of the two connecting components are connected to the same limit component, and the limit component is connected to the top of the workbench.

[0013] In one possible design, the connecting assembly includes a connecting plate fixedly mounted on the top of one side of a U-shaped bracket, a mounting rod slidably connected through the connecting plate, the top end of the mounting rod is fixedly connected to the bottom of the pressure plate, and the bottom end of the mounting rod is connected to the limit assembly.

[0014] In a possible design, the limit assembly includes a crossbeam fixedly mounted and connected to the bottom ends of two mounting rods located on the same side. There are two crossbeams, a limit frame fixedly mounted on the top of the crossbeam, a limit plate slidably connected inside the limit frame, a same clamping rod is fixedly mounted through the two limit plates, and a hook located between the two crossbeams is fixedly mounted on the top of the workbench, and the hook is movably clamped to the clamping rod.

[0015] In a possible design, a compression spring is fixedly mounted on an inner wall of one side of the limiting frame, and one end of the compression spring is fixedly connected to one side of the limiting plate.

[0016] In the present application, the two plugs on the wiring harness are firstly arranged on the corresponding U-shaped brackets respectively, and at this time the two cross beams can be pushed downward to drive the four mounting rods to move downward, and when the mounting rods move downward, the pressure plate can be driven downward until the pressure plate contacts the top of the plug, and then the plug can be driven downward to be plugged with the corresponding connector, and when the plug moves downward, the U-shaped bracket can be driven downward, so that the moving ring can be driven downward by the connecting rod to stretch the tension spring, so that the tension spring is in a stressed state, and the tension spring in a stressed state can elastically support the U-shaped bracket through the moving ring and the connecting rod, so as to be able to push the U-shaped bracket to reset upward, and when the cross beam moves downward, it can drive the clamping rod through the limit frame. When the lever is in the downward position, it will come into contact with the inclined plane at the top of the hook. When the lever continues to move downward, it can move laterally under the action of the inclined plane, thereby driving the two limit plates to move laterally, and making the two compression springs be in a stressed state. Therefore, when the lever moves to the bottom of the hook, it will lose support, and the two compression springs in a stressed state can push the two limit plates to move in the opposite direction, so that the lever can be moved to a position where it is clamped with the hook. At this time, the height of the two beams can be limited. Furthermore, the pressure plate can be used to press the plug, and the baffle can limit the plug laterally, thereby preventing the plug from moving laterally, thereby achieving stable connection with the connector, and preventing the problem of detachment.

[0018] In the utility model, the conduction detection platform can push the limit assembly downward after the plug is set on the U-shaped bracket through the positioning mechanism, that is, the two pressure plates can be driven to move downward through the four connecting assemblies, so that the pressure plates can contact the corresponding plugs, and then when the pressure plates move downward, the plugs can be driven to move downward, and can be plugged and connected with the corresponding connectors for electrical conduction, and after the limit assembly performs the brake limit brake, the two plugs can be stably braked and limited;

[0019] After the two plugs are respectively arranged on the corresponding U-shaped brackets, the two cross beams can be pushed downward to move the plugs into the corresponding connectors, so that the plugs and the connectors maintain a stable plug-in fit, and the wiring harness is tested for conduction. In the process of the test, the two plugs can be stably limited, which can effectively prevent the problem of separation. BRIEF DESCRIPTION OF THE DRAWINGS

The top and bottom ends of the tension spring 16 are respectively fixedly connected to the bottom of the connector 6 and the top of the moving ring 9. After the detection of the wiring harness 7 is completed, the elastic force of the tension spring 16 can be used to drive the moving ring 9 to move upward, so that the connecting rod 10 can be used to push the positioning mechanism to move upward, so that the positioning of the wiring harness 7 can be released, and the wiring harness 7 can be conveniently taken out.

[0030] Both ends of the wiring harness 7 are fixedly connected with plugs 8, and the plugs 8 are electrically plugged into one side of the corresponding connector 6. The plugs 8 are clamped with the positioning mechanism. Plugs 8 are provided at both ends of the wiring harness 7 and can be electrically plugged into the two connectors 6 respectively, so that the wiring harness 7 for detection can be electrically connected with the wiring harness tester 2 so that the wiring harness 7 can be tested for conductivity.

[0031] The positioning mechanism includes a baffle 11 fixedly mounted on the top of the connecting rod 10, the baffle 11 contacts one side of the corresponding plug 8, a U-shaped bracket 12 is symmetrically fixedly mounted on one side of the baffle 11, the plug 8 is clamped on the U-shaped bracket 12, and connecting components are installed on the top of both sides of the U-shaped bracket 12, and the same pressure plate 15 is installed on the top of the two connecting components, and the pressure plate 15 is used to position and clamp the plug 8.

[0032] The present application can be used in the field of wire harness detection technology, and can also be used in other fields applicable to the present application.

[0033] Example 2

[0034] refer to Figure 2 and 3, improved on the basis of embodiment 1: a conduction detection platform, which is applied to the field of wire harness detection technology, the connecting component includes a connecting plate 13 fixedly installed on the top of one side of the U-shaped bracket 12, and a mounting rod 14 is slidably connected through the connecting plate 13. The top of the mounting rod 14 is fixedly connected to the bottom of the pressure plate 15, and the bottom end of the mounting rod 14 is connected to the limit assembly. The sliding connection between the mounting rod 14 and the connecting plate 13 can support the longitudinal sliding of the pressure plate 15, and when the mounting rod 14 moves downward with the limit assembly, it can drive the pressure plate 15 to move downward so that the plug 8 can be positioned and braked.

[0035] The limiting assembly includes a crossbeam 17 fixedly installed and connected to the bottom ends of two mounting rods 14 located on the same side. There are two crossbeams 17. A limiting frame 19 is fixedly installed on the top of the crossbeam 17. A limiting plate 20 is slidably connected inside the limiting frame 19.

The hook 18 and the clamping rod 21 are movably clamped. When the crossbeam 17 is pushed downward, the pressure plate 15 can be driven to move downward through the corresponding mounting rod 14, so that the plug 8 can be positioned and clamped. When the clamping rod 21 moves downward with the crossbeam 17 to be clamped with the hook 18, the two crossbeams 17 can be limited, so that the plug 8 can be stably clamped and positioned.

[0036] A compression spring 22 is fixedly installed on the inner wall of one side of the limit frame 19, and one end of the compression spring 22 is fixedly connected to one side of the limit plate 20. When the clamping rod 21 moves downward with the cross beam 17, it can contact the inclined surface at the top of the hook 18. At this time, when the clamping rod 21 continues to move downward, it can be laterally displaced under the action of the inclined surface, thereby driving the two limit plates 20 to move laterally, so that the two compression springs 22 are in a stressed state. Therefore, when the clamping rod 21 moves to the bottom of the hook 18, it will lose support. The two compression springs 22 in a stressed state can push the two limit plates 20 to move in the opposite direction, so that the clamping rod 21 can move to a position where it is clamped with the hook 18.
