Description

Technical Field

[0001] This invention relates to the field of new energy electric vehicle technology, and in particular to a quick-connect plug for high-voltage testing of electric drive controllers. Background Technology

[0002] The electric drive controller is an important component of new energy electric vehicles. It is specifically matched and configured with the electric drive to control the operation of the electric drive.

[0003] During testing of the electric drive controller, the testing equipment must first be electrically connected to the DC bus on the controller before the equipment can operate and acquire the controller's operating parameters. Currently, existing testing equipment connects to the controller's DC bus by inserting a high-voltage harness into the controller. Specifically, the controller's top cover must be opened, and bolts are used to connect and tighten the high-voltage harness plug to the DC bus. This connection method is complex, time-consuming, and compromises the airtightness of the top cover during installation. After testing, the cover needs to be resealed, and the residual adhesive from the previous sealing process inevitably affects subsequent sealing, resulting in poor overall sealing of the controller and reduced product performance. Summary of the Invention

[0004] Therefore, it is necessary to provide a quick-connect plug for high-voltage testing of electric drive controllers to address the aforementioned technical problems.

[0005] Specifically, a quick-connect plug for high-voltage testing of an electric drive controller is provided for electrical connection to the DC busbar of the electric drive controller. The quick-connect plug includes a plug body, a busbar connector, a spindle, and a handle. The busbar connector is correspondingly arranged with the spindle. The spindle extends through the plug body, and one end of the spindle extending out of the plug body is connected to the corresponding busbar connector. An elastic body is provided between the spindle and the plug body along the axial direction of the spindle.

[0006] The handle has a push block, which is rotatably mounted on the main shaft and abuts against the plug body to control the relative position between the main shaft and the plug body under the action of the push block, and to compress and deform the elastomer.

[0007] In this application, the quick-connect plug can be directly inserted into the electric drive controller by cooperating with the push block on the handle, the plug body, and the spindle. When the handle drives the push block against the plug body and rotates, the action and reaction forces can be used to move the spindle relative to the plug body, thereby compressing the elastic body and deforming it. When the quick-connect plug is inserted into the electric drive controller and the busbar connector is electrically connected to the DC busbar, the deformed elastic body can lock the quick-connect plug on the electric drive controller, allowing for quick insertion and removal of the quick-connect plug. This not only simplifies operation and reduces time, but also avoids disassembling the top cover of the electric drive controller, thus ensuring the overall sealing of the electric drive controller after the quick-connect plug is in use.

[0008] In one embodiment, the push block has a first abutting surface and a second abutting surface, the first abutting surface is connected to the second abutting surface, and the push block can abut against the plug body through the first abutting surface or the second abutting surface;

[0009] The first contact surface is set as a plane, and the second contact surface is set as an arc-shaped convex surface.

[0010] It is understandable that the push block engages with the plug body through the first and second abutting surfaces, thereby achieving the engagement between the push block and the plug body. Furthermore, by utilizing the shape characteristics of the first and second abutting surfaces, the push block can push against the plug body during the process of switching from the first to the second abutting surface, thereby driving the main shaft to move relative to the plug body.

[0011] In one embodiment, the number of spindles is two, and the two spindles are arranged at an interval on the plug body;

[0012] Along the radial direction of the main shaft, a connecting shaft is inserted between the two main shafts, and the push block is disposed between the two main shafts and rotatably connected to the connecting shaft.

[0013] It is understandable that the push block is rotatably mounted on the connecting shaft between the two main shafts, thereby realizing the rotational connection between the main shaft and the push block, so that the push block can drive the two main shafts to move relative to the plug body through the connecting shaft.

[0014] In one embodiment, the main shaft extends through the elastic body, wherein a baffle is formed at one end of the main shaft extending out of the elastic body, the baffle abutting against the elastic body to prevent the elastic body from detaching from the main shaft.

[0015] It is understandable that the installation of the elastomer on the spindle is achieved by using the structure of the baffle on the spindle and the abutment between the baffle and the elastomer.

[0016] In one embodiment, the quick-connect plug further includes a gasket disposed between the elastomer and the plug body, and the plug body can act on the elastomer through the gasket to limit the elastomer to the stop.

[0017] It is understandable that the structure of the aforementioned gasket allows the plug body to limit the elastomer to the stop via the gasket, thereby buffering the action of the plug body on the elastomer and reducing wear on the elastomer during use of the quick-connect plug.

[0018] In one embodiment, the busbar connector includes a spindle and a connecting spring, the connecting spring being mounted on the spindle;

[0019] The connecting spring has an elastic protrusion that can be deformed under pressure to limit the busbar connector to the DC busbar.

[0020] It is understandable that the structure of the quick-connect plug is specifically realized through the above-mentioned mandrel and connecting spring. Furthermore, by utilizing the elastic deformation of the elastic protrusion on the connecting spring, the assembly limit between the busbar connector and the DC busbar in the electric drive controller can be achieved, which can further improve the stability of the connection between the busbar connector and the DC busbar.

[0021] In one embodiment, the plug body includes a plug positioning plate, a main sleeve, and a connecting block. The main sleeve is correspondingly disposed with respect to the main shaft, wherein the main shaft is slidably mounted in the corresponding main sleeve.

[0022] The main socket is installed on the plug positioning plate and abuts against the connecting block, and one end of the connecting block opposite to the main socket abuts against the push block.

[0023] It is understandable that the structure of the plug body is specifically achieved through the above-mentioned plug positioning plate, main socket and connecting block.

[0024] In one embodiment, the plug body further includes an adjustment plate, which is mounted on the main socket and abuts against the connecting block to adjust the relative position between the connecting block and the main socket.

[0025] It is understandable that the structure of the adjustment plate allows the quick-connect plug to adjust the positional relationship between the connecting block and the push block. This achieves the purpose of adjusting the movement distance of the spindle relative to the plug body during the operation of the quick-connect plug, and also adjusts the degree of deformation of the elastic body to ensure that the quick-connect plug is locked on the electric drive controller.

[0026] In one embodiment, the plug positioning plate is provided with a positioning member that extends outward relative to the plug positioning plate along the axial direction of the main shaft.

[0027] It is understandable that, through the structural design of the aforementioned positioning component, when the quick-connect plug is inserted into the electric drive controller, the positioning component and the electric drive controller can be used to ensure the accuracy of the quick-connect plug's position when connected to the electric drive controller.

[0028] In one embodiment, the quick-connect plug further includes a connecting connector, through which the busbar connector is mounted on the corresponding spindle.

[0029] It is understandable that the above-mentioned connection joint structure is used to specifically achieve the assembly connection between the busbar connector and the spindle.

[0030] Compared with the prior art, this application has the following advantages:

[0031] The quick-connect plug for high-voltage testing of the electric drive controller claimed in this application allows the plug to be directly inserted into the electric drive controller. The engagement between the push block on the handle and the plug body and spindle allows the handle to rotate, causing the push block to press against the plug body. This action and reaction forces cause the spindle to move relative to the plug body, deforming the elastic body. When the quick-connect plug is inserted into the electric drive controller and the busbar connector is electrically connected to the DC busbar, the deformed elastic body locks the quick-connect plug onto the controller. This allows for rapid insertion and removal of the quick-connect plug, simplifying operation, reducing time, and eliminating the need to disassemble the top cover of the electric drive controller, thus ensuring the overall sealing of the electric drive controller after the quick-connect plug is used.

[0045] The quick-connect plug 100 for high-voltage testing of electric drive controllers claimed in this application is used to electrically connect to the DC busbar (not shown) of the electric drive controller (not shown). Specifically, when testing the electric drive controller with testing equipment, the testing equipment can be electrically connected to the electric drive controller through the quick-connect plug 100.

[0046] like Figures 1 to 3As shown, an embodiment of this application provides a quick-connect plug for high-voltage testing of an electric drive controller, comprising a plug body 10, a busbar connector 20, a spindle 30, and a handle 40. The busbar connector 20 is correspondingly arranged with the spindle 30. The spindle 30 passes through the plug body 10, and one end of the spindle 30 extending out of the plug body 10 is connected to the corresponding busbar connector 20. An elastic body 50 is provided between the spindle 30 and the plug body 10 along the axial direction of the spindle 30. The handle 40 has a push block 41, which is rotatably mounted on the spindle 30 and abuts against the plug body 10. Under the drive of the push block 41, the relative position between the spindle 30 and the plug body 10 is controlled, and the elastic body 50 is deformed by compression. In other words, the quick-connect plug 100 of this application can be directly inserted into the electric drive controller, and then the relative position between the spindle 30 and the plug body 10 can be changed by driving the handle 40 to achieve the purpose of deforming the elastic body 50. It should be noted that the busbar connector 20 on the quick-connect plug 100 is electrically connected to the test equipment through a high-voltage wiring harness. When the quick-connect plug 100 is inserted into the electric drive controller, the quick-connect plug 100 can drive the busbar connector 20 and the elastomer 50 to be inserted into the electric drive controller together. When the quick-connect plug 100 is inserted into the electric drive controller and the busbar connector 20 is electrically connected to the DC busbar, the plug body 10 abuts against the electric drive controller and remains stationary relative to the electric drive controller.

[0047] It is understood that when the quick-connect plug 100 of this application is inserted into the electric drive controller and the busbar connector 20 is electrically connected to the DC busbar, the deformed elastic body 50 can be used to lock the quick-connect plug 100 on the electric drive controller. Specifically, the tight fit between the deformed elastic body 50 and the channel wall of the channel on the electric drive controller for the busbar connector 20 to be inserted is used to achieve the limiting, so that the quick-connect plug 100 can be quickly inserted and removed from the electric drive controller. This not only makes the operation simple and saves time, but also avoids disassembling the top cover (not shown) of the electric drive controller, thereby ensuring the sealing of the entire electric drive controller product after the action of the quick-connect plug 100.

[0048] In one embodiment, the plug body 10 includes a plug positioning plate 11, a main sleeve 12, and a connecting block 13. The main sleeve 12 is correspondingly disposed with the main shaft 30, wherein the main shaft 30 is slidably mounted in the corresponding main sleeve 12. The main sleeve 12 is mounted on the plug positioning plate 11 and abuts against the connecting block 13. One end of the connecting block 13 facing away from the main sleeve 12 abuts against the push block 41. It should be noted that when the quick-connect plug 100 drives the busbar connector 20 to be inserted into the electric drive controller, the plug positioning plate 11 abuts against the electric drive controller and remains relatively stationary.

[0049] The plug body 10 also includes an adjustment plate 14, which is mounted on the main sleeve 12 and abuts against the connecting block 13. The adjustment plate 14 is used to adjust the relative position between the connecting block 13 and the main sleeve 12, so that the quick-connect plug 100 can adjust the positional relationship between the connecting block 13 and the push block 41 by using the adjustment plate 14. This achieves the purpose of adjusting the movement distance of the spindle relative to the plug body 10 when the quick-connect plug 100 is working, and also achieves the adjustment of the deformation degree of the elastic body 50, so as to ensure that the quick-connect plug 100 is locked on the electric drive controller.

[0050] like Figure 3 As shown, the main sleeve 12 has an extension protrusion 121, which is partially inserted into the connecting block 13. The adjusting plate 14 is threaded onto the extension protrusion 121 of the main sleeve 12. In this way, when the quick connector 100 is in use, the relative position between the main sleeve 12 and the connecting block 13 can be adjusted by turning the adjusting plate 14. This utilizes the structural characteristics of the threaded connection to facilitate the adjustment of the relative position between the main sleeve 12 and the connecting block 13.

[0051] like Figure 2 , Figure 3 As shown, the plug positioning plate 11 is provided with a positioning member 111. Along the axial direction of the spindle 30, the positioning member 111 extends outward relative to the plug positioning plate 11, so that when the quick-connect plug 100 is inserted into the electric drive controller, the positioning member 111 and the electric drive controller can be engaged to ensure the accuracy of the quick-connect plug 100's position when connected to the electric drive controller. It should be noted that the positioning member 111 on the plug positioning plate 11 is specifically configured as a positioning pin, and the electric drive controller has a slot for matching the positioning member 111, so as to meet the usage requirements of the positioning member 111 and the electric drive controller for engagement.

[0052] The busbar connector 20 is used in the quick-connect plug 100, specifically for contacting and mating with the DC busbar to achieve an electrical connection between the quick-connect plug 100 and the DC busbar.

[0053] like Figures 1 to 3 As shown, the busbar connector 20 includes a spindle 21 and a connecting spring 22, with the connecting spring 22 mounted on the spindle 21. The connecting spring 22 has an elastic protrusion 221, which can be deformed under pressure to limit the busbar connector 20 to the DC busbar. This enables the assembly of the busbar connector 20 when it is electrically connected to the DC busbar, thereby further improving the connection stability between the busbar connector 20 and the DC busbar.

[0054] like Figure 1As shown, the elastic protrusion 221 is configured as an arc shape, wherein the elastic protrusion 221 extends out of the mandrel 21 and forms a preset gap with the mandrel 21 so that the elastic protrusion 221 can deform under pressure.

[0055] like Figures 1 to 3 As shown, there are two main shafts 30, which are arranged alternately on the plug body 10. A connecting shaft 32 is inserted between the two main shafts 30 along their radial direction. A push block 41 is positioned between the two main shafts 30 and rotatably connected to the connecting shaft 32, thereby achieving the rotatable connection between the main shafts 30 and the push block 41. This allows the push block 41 to drive the two main shafts 30 to move relative to the plug body 10 via the connecting shaft 32. It should be noted that the connecting shaft 32 can specifically be a pin 321, and a ring 3211 is connected to the portion of the pin 321 that extends beyond the main shaft 30 to prevent the pin 321 from detaching from the main shaft 30. Simultaneously, the quick-connect plug 100 as a whole can be suspended by the ring 3211.

[0056] In one embodiment, the spindle 30 is disposed through the elastic body 50, wherein a stop 31 is formed at one end of the spindle 30 extending out of the elastic body 50, the stop 31 abuts against the elastic body 50 to restrict the elastic body 50 from detaching from the spindle 30, thereby specifically realizing the installation of the elastic body 50 on the spindle 30.

[0057] like Figure 2 As shown, the quick-connect plug 100 also includes a gasket 51, which is disposed between the elastic body 50 and the plug body 10. The plug body 10 can act on the elastic body 50 through the gasket 51 to limit the elastic body 50 to the stop 31. When the quick-connect plug 100 is in use, the main socket 12 on the plug body 10 can act on the elastic body 50 through the gasket 51. This can buffer the action of the plug body 10 on the elastic body 50, thereby reducing the wear of the elastic body 50 when the quick-connect plug 100 is in use.

[0058] like Figure 5As shown, the push block 41 has a first abutment surface 411 and a second abutment surface 412. The first abutment surface 411 and the second abutment surface 412 are connected, and the push block 41 can abut against the plug body 10 through either the first abutment surface 411 or the second abutment surface 412. The first abutment surface 411 is a flat surface, and the second abutment surface 412 is an arc-shaped convex surface. This allows the push block 41 to push against the plug body 10 during the transition from the first abutment surface 411 to the second abutment surface 412, thereby driving the main shaft 30 to move relative to the plug body 10. It should be noted that there are two second abutment surfaces 412, located on either side of the first abutment surface 411. This ensures that when the handle 40 is rotated in two opposite directions, it can push against the plug body 10.

[0059] In one embodiment, the quick-connect plug 100 further includes a connecting connector 60, through which the busbar connector 20 is mounted on the corresponding spindle 30, thereby specifically realizing the assembly connection between the busbar connector 20 and the spindle 30. It should be noted that the connecting connector 60 is made of plastic steel.

[0060] Specifically, the connecting joint 60 is locked to the spindle 21 on the busbar connector 20 with screws, and is connected and fixed to the main shaft 30 by threads.

[0061] like Figure 4 As shown, the main shaft 30 of this application has a wire harness channel 33, and the main socket 12 of the plug body 10 has a through hole 122, so that the high voltage wire harness electrically connected to the spindle 21 of the busbar connector 20 can extend outward through the wire harness channel 33 and the through hole 122 in sequence and connect to the test equipment.

[0062] As can be seen from the above, when the quick-connect plug 100 of this application is electrically connected to the electric drive controller, the female connector 20 on the quick-connect plug 100 can be inserted into the electric drive controller until the plug positioning plate 11 on the plug body 10 abuts against the electric drive controller. During this process, the positioning member 111 on the plug positioning plate 11 is aligned with the slot on the electric drive controller, and the positioning member 111 and the two female connectors 20 form a triangular positioning, which can ensure the stable accuracy of the female connector 20 when connected to the DC bus in the electric drive controller; then the handle 40 is manually pressed so that the push block 41 on the handle 40 abuts against the plug. The connecting block 13 on the main body 10 rotates, causing the contact between the push block 41 and the connecting block 13 to switch from the first contact surface 411 to the second contact surface 412. Due to the positioning of the connecting block 13, the push block 41 drives the main shaft 30 to move relative to the plug body 10 in the axial direction using action and reaction forces, and compresses the elastic body 50 to deform. This allows the deformed elastic body 50 to cooperate with and lock with the electric drive controller, thus realizing the insertion of the quick-connect plug 100 on the electric drive controller and ensuring the stability of the electrical connection between the quick-connect plug 100 and the DC bus on the electric drive controller. Conversely, the handle 40 is rotated in the opposite direction, causing the contact between the push block 41 and the connecting block 13 to switch from the second contact surface 412 to the first contact surface 411. This drives the main shaft 30 to move in the opposite direction, releasing the compression on the elastic body 50, allowing the elastic body 50 to elastically reset, and releasing the lock of the quick-connect plug 100 on the electric drive controller.

[0063] In summary, the quick-connect plug 100 of this application enables rapid insertion and removal between the electric drive controller and the controller. This not only simplifies operation and reduces working time, but also avoids disassembling the top cover (not shown) of the electric drive controller, thereby ensuring the overall sealing of the electric drive controller product after the quick-connect plug 100 is applied.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
