Description

Technical Field

[0001] This utility model relates to the field of brush connector technology, and more specifically, to a testing device for the coil connection strength of a brush connector. Background Technology

[0002] A brush plate is a conductive component that forms an electrical connection by making sliding contact with moving parts. Brush connectors are usually used to connect the brushes inside a motor to provide power to the motor. They are an indispensable part of the motor. Depending on the structure and purpose of the brush connector, it can be made of a variety of different materials.

[0003] For example, CN215065785U discloses a connector connection strength testing device, including a housing with a fitted cover fixedly fitted to the top surface of the housing, and a fixing mechanism inside the housing. A pull rope is provided on one side of the fixing mechanism, and multiple rectangular holes are evenly spaced on the pull rope. In this utility model, the connector is placed above two recessed blocks, and the threaded rod is rotated to engage with the embedded plate and descend, thereby embedding the rotating bar above the threaded rod between the two recessed blocks, fixing the connector between the two recessed blocks and the rotating bar. Then, the connector is pressed with the pull rope, and the pull ring is pulled by a person to cause the tension gauge to operate. The connection strength of the connector is obtained from the tension gauge data. However, this testing device is designed to test the connection strength between the connector and the wire. When applied to the coil connection strength in a brush connector, its testing effect is poor.

[0004] To facilitate the testing of the coil connection strength within a brush connector, a testing device for the coil connection strength of a brush connector is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a testing device for the coil connection strength of a brush connector, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a testing device for the coil connection strength of a brush connector, comprising a testing body and a traction body disposed on the top of the testing body;

[0007] The test body includes a test platform, a vertical rod and an electric lift mounted on the top of the test platform. A movable structure for fixing the brush connector is slidably connected to the vertical rod. The bottom of the movable structure is connected to the electric lift, and the electric lift is used to drive the movable structure to move up and down along the vertical rod.

[0008] The pulling body includes a fixed bracket set at the top of the vertical rod. A tension meter is provided at the bottom of the fixed bracket. A hook is fixed at the bottom of the tension meter by a clamping kit. The hook is used to hook the coil or housing of the brush connector. The electric lift drives the movable structure to move down. After the hook is pulled, the connection strength of the brush connector coil or housing is measured by the tension meter.

[0009] As a further improvement to this technical solution, the movable structure includes a movable bracket that is slidably connected to the vertical rod at both ends. The bottom of the movable bracket is connected to the electric lift. The top of the movable bracket is provided with a fixing kit. The fixing kit includes an upper plate and a slider that is slidably connected to the upper plate. The top center of the slider is provided with a slot. The groove shape of the slot matches the shape of the brush connector. The top edge of the slider is provided with multiple pressure plates for pressing the brush connector.

[0010] As a further improvement to this technical solution, the top of the movable support is provided with a hollow plate, and the bottom of the upper plate passes through the hollow plate and is connected to the lower plate.

[0011] As a further improvement to this technical solution, the upper surface of the lower plate is provided with several micro-protrusions, and the lower plate is engaged with the lower top surface of the hollow plate through the micro-protrusions. The vertical rod is provided with a limiting ring for limiting the vertical movement range of the movable structure.

[0012] As a further improvement to this technical solution, the clamping kit includes a connecting handle connected to the bottom of the tension meter. The bottom of the connecting handle is provided with a first clamping block and a second clamping block. The connecting handle clamps and fixes the hook through the first clamping block and the second clamping block provided at the bottom.

[0013] As a further improvement to this technical solution, one end of the bottom of the connecting handle is fixedly connected to the first clamping block, and a screw is rotatably connected inside the second clamping block. The end of the screw passes through the first clamping block, and the screw is threadedly connected to the first clamping block.

[0014] As a further improvement to this technical solution, the inner walls of the first clamping block and the second clamping block are provided with clamping grooves that match the shape of the hook.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In the test device for the coil connection strength of the brush connector, the hook contacts the brush connector and hooks the coil or housing of the brush connector. The electric lift then drives the movable structure to move down along the vertical rod. After the hook is pulled, the connection strength of the coil or housing of the brush connector is measured by the tension meter. The measurement process is simple and easy to use.

[0017] 2. In the test device for the coil connection strength of the brush connector, when the electric lift moves the movable structure downward and the hook catches the coil or the housing, the lower plate located in the hollow plate is moved upward until the micro-convex contacts the micro-groove and gets stuck, thereby avoiding horizontal displacement during measurement and further ensuring the measurement accuracy of the coil connection strength.

[0029] Please see Figures 1-6 As shown, this embodiment provides a testing device for the coil connection strength of a brush connector, including a test body 1 and a pulling body 2 disposed on the top of the test body 1;

[0030] The test body 1 includes a test platform 11, a vertical rod 12 and an electric lift 13 disposed on the top of the test platform 11. A movable structure 14 for fixing the brush connector is slidably connected on the vertical rod 12. The bottom of the movable structure 14 is connected to the electric lift 13. The electric lift 13 is used to drive the movable structure 14 to move up and down along the vertical rod 12.

[0031] The traction body 2 includes a fixed bracket 21 set at the top of the vertical rod 12. A tension meter 22 is provided at the bottom of the fixed bracket 21. A hook 24 is fixed at the bottom of the tension meter 22 by a clamping kit 23. The hook 24 is used to hook the brush connector. After the brush connector is fixed by the movable structure 14, the electric lift 13 drives the movable structure 14 to move upward along the vertical rod 12, so that the hook 24 contacts the brush connector and hooks the coil or housing of the brush connector. The electric lift 13 then drives the movable structure 14 to move downward along the vertical rod 12. After the hook 24 is pulled, the connection strength of the coil or housing of the brush connector is measured by the tension meter 22.

[0032] First, to facilitate the fixing of the brush connector, the movable structure 14 includes a movable bracket 141 with both ends slidably connected to the vertical rod 12. The bottom of the movable bracket 141 is connected to the electric lift 13. The top of the movable bracket 141 is provided with a fixing kit 143. The fixing kit 143 includes an upper plate 1431 and a slider 1432 slidably connected to the upper plate 1431. The top center of the slider 1432 is provided with a slot 1433. The groove shape of the slot 1433 matches the shape of the brush connector. The top edge of the slider 1432 is provided with multiple pressure plates 1434 for pressing the brush connector. The brush connector is inserted into the groove of the slot 1433, and the pressure plates 1434 are used to press the brush connector to prevent the brush connector from falling out of the slot 1433. After the installation of the brush connector is completed, the slider 1432 is slid into the top of the upper plate 1431 for fixing.

[0033] After the fixing is completed, the electric lifting platform 13 drives the movable structure 14 to move up along the vertical rod 12 so that the brush connector is close to the hook 24. In order to facilitate the hook 24 to hook the coil or housing of the brush connector, the top of the movable bracket 141 is provided with a hollow plate 142. The bottom of the upper plate 1431 passes through the hollow plate 142 and is connected to the lower plate 1435. By moving the lower plate 1435 inside the hollow plate 142, the upper plate 1431 can be moved, thereby adjusting the position of the brush connector so that the hook 24 can hook the coil or housing.

[0034] After the hook 24 catches the coil or housing, the electric lift 13 drives the movable structure 14 to move downward, causing the hook 24 to pull the coil or housing. During this process, in order to avoid horizontal movement affecting the measurement results, the upper surface of the lower plate 1435 is provided with several micro-protrusions 1436, and the lower surface of the top of the hollow plate 142 is provided with corresponding micro-grooves. The lower plate 1435 is engaged with the lower surface of the top of the hollow plate 142 through the micro-protrusions 1436, and the vertical rod 12 is provided with a function to limit the vertical movement range of the movable structure 14. When adjusting the position of the brush connector, the lower plate 1435 is located at a low position inside the hollow plate 142, and the micro-protrusion 1436 does not contact the micro-groove of the hollow plate 142, so it does not affect the movement of the lower plate 1435 inside the hollow plate 142. When the electric lifting platform 13 drives the movable structure 14 to move down and the hook 24 hooks the coil or the housing, the lower plate 1435 located inside the hollow plate 142 is driven to move up until the micro-protrusion 1436 contacts the micro-groove and gets stuck, thereby avoiding horizontal displacement during measurement and ensuring measurement accuracy.

[0035] In order to facilitate the clamping of the hook 24, the clamping kit 23 includes a connecting handle 231 connected to the bottom of the tension meter 22. The bottom of the connecting handle 231 is provided with a first clamping block 232 and a second clamping block 233. The connecting handle 231 clamps and fixes the hook 24 through the first clamping block 232 and the second clamping block 233 at the bottom.

[0036] To facilitate the replacement and installation of the hook 24, one end of the connecting handle 231 is fixedly connected to the first clamping block 232. A screw 234 is rotatably connected inside the second clamping block 233. The end of the screw 234 passes through the first clamping block 232 and is threadedly connected to the first clamping block 232. By rotating the screw 234, the second clamping block 233 is moved closer to or further away from the first clamping block 232, thereby facilitating the adjustment of the distance between the first clamping block 232 and the second clamping block 233. This is beneficial for the replacement and installation of the hook 24. Furthermore, the inner walls of the first clamping block 232 and the second clamping block 233 are provided with clamping grooves 235 that match the shape of the hook 24. During installation and use, by inserting the hook 24 into the clamping grooves 235, the installation difficulty can be reduced, and the skewness of the hook 24 during testing can be avoided.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
