Description

Technical Field

[0001] This application belongs to the technical field of conductive connectors, specifically relating to a connector for a charging pile rectifier cabinet. Background Technology

[0002] With the development of new energy vehicles, group charging piles (multi-gun centralized charging piles) have become the mainstream equipment for high-power charging scenarios due to their high efficiency and compact layout. The rectifier cabinet, as the core component of the charging pile, is responsible for converting AC power into high-voltage DC power. The connector, as an important component of the rectifier cabinet, can ensure the conductivity stability of the wiring harness.

[0003] Existing connectors include a mounting base, conductive posts on the mounting base, and a protective cover on the mounting base. One side of the protective cover has a through-hole for the wire harness to pass through. The conductive posts have an inner end inside the rectifier cabinet housing and an outer end outside the housing. When using the connector, the inner end of the conductive post is crimped with the conductive wire harness and then fixedly connected to the copper busbar of the rectifier unit. The mounting base is then installed on the rectifier cabinet housing, and the conductive terminals of the wire harness outside the housing are connected to the outer end of the conductive post. Finally, the protective cover is installed on the mounting base so that the wire harness outside the housing extends out of the protective cover through the through-hole. However, because the through-hole is located on one side of the protective cover, and the wire harness outside the housing needs to pass through the through-hole, the installation direction of the wire harness outside the housing is unique. This restricts the layout of the wire harness outside the housing, making it difficult to improve space utilization and resulting in a cluttered wire harness layout, which inconveniences later maintenance. Utility Model Content

[0004] This application provides a connector for a charging pile rectifier cabinet to improve the flexibility of the installation direction of the wiring harness and conductive post, improve space utilization, and make the layout of the wiring harness more regular, so as to facilitate later maintenance.

[0005] The technical solution adopted in this application is as follows:

[0006] A connector for a charging pile rectifier cabinet includes:

[0007] Mounting base, the mounting base having an outer end face and an inner end face opposite to the outer end face;

[0008] A conductive post is disposed on the mounting base, and the conductive post has a first end protruding from the outer end face and a second end protruding from the inner end face;

[0009] A protective cover, wherein the protective cover is provided with a passage for the wire harness to pass through, the protective cover is provided on the outer end face and can cover the outside of the first end;

[0010] One of the outer end face and the protective cover is provided with a plurality of connection positions evenly spaced along its circumference, and the other of the two is provided with a plurality of connectors that can be connected and cooperate with the connection positions evenly spaced along its circumference. The connectors are provided corresponding to the connection positions, so that when any connector is connected and cooperated with one of the connection positions, the remaining connectors can be connected to their corresponding connection positions.

[0011] By adopting the above technical solution, when using the connector in this application, first connect the second end of the conductive post to the wire harness, then fix the wire harness to the copper busbar of the rectifier unit, then fix the mounting base to the housing of the rectifier cabinet, then connect the wire harness outside the housing to the first end of the conductive post, and then install the protective cover to the mounting base so that the connector is connected to the connection position, and at the same time, the wire harness is located in the through port to complete the installation of the connector.

[0012] Because one of the outer end face and the protective cover has multiple connection positions evenly spaced along its circumference, and the other has multiple connectors evenly spaced along its circumference that can connect and mate with the connection positions, and the connectors are set corresponding to the connection positions, the operator can adjust the protective cover according to the position of the wire harness so that the wire harness is located in the passage after the protective cover is installed on the mounting base. This makes the installation position of the wire harness no longer limited by the relative position of the protective cover and the mounting base, increasing the number of directions in which the wire harness can be installed on the first end of the conductive post. This avoids the situation where the wire harness layout outside the housing is restricted, thereby improving the space utilization rate outside the rectifier cabinet housing and making the wire harness layout more regular, so as to facilitate later maintenance.

[0013] Optionally, the protective cover has an clearance notch on its side, and the connector is a snap-fit ​​arm located in the clearance notch, which can snap into the connection position.

[0014] By adopting the above technical solution, when installing the protective cover, first align the port with the wire harness connected to the first end, and simultaneously align the snap-fit ​​arm with the connection position. Then, apply a pushing force to the protective cover in the direction of the mounting base so that the protective cover moves towards the mounting base. Finally, the snap-fit ​​arm and the connection position snap together to complete the installation of the protective cover onto the mounting base. This reduces the difficulty of installing the protective cover and improves the installation efficiency.

[0015] When removing the protective cover from the mounting base, press the snap-fit ​​arm to separate it from the connection point. Then, apply a pulling force away from the mounting base to separate the protective cover from the mounting base. This process only requires pressing the snap-fit ​​arm and applying a pulling force away from the mounting base, thus facilitating the removal of the protective cover.

[0016] Optionally, the connection position is a snap-fit ​​groove provided on the outer end face. The snap-fit ​​arm has a fixed end that is fixedly connected to the protective cover and a free end opposite to the fixed end. The free end protrudes from the end face of the protective cover, and a snap-fit ​​protrusion is provided on the outer side of the free end. The free end can extend into the snap-fit ​​groove so that the snap-fit ​​protrusion engages with the groove wall of the snap-fit ​​groove.

[0017] By adopting the above technical solution, when installing the protective cover, first align the port with the wire harness connected to the first end, and simultaneously align the snap-fit ​​arm with the snap-fit ​​groove. Then, apply a pushing force to the protective cover in the direction of the mounting base, so that the protective cover moves towards the mounting base. Finally, the free end of the snap-fit ​​arm extends into the snap-fit ​​groove, and the snap-fit ​​protrusion engages with the groove wall to complete the installation of the protective cover. This facilitates the installation of the protective cover and also increases the connection stability between the protective cover and the mounting base.

[0018] Optionally, there are two locking arms arranged opposite each other, and at least 2N locking slots are provided, where N satisfies: N≥2.

[0019] By adopting the above technical solution, when removing the protective cover from the mounting base, the operator's fingers simultaneously press down on both locking arms, causing them to move towards each other. This separates the locking protrusion from the groove wall of the locking slot. Then, a pulling force is applied to the protective cover away from the mounting base, causing the locking arms to disengage from the locking slots, thus completing the removal of the protective cover from the mounting base. Since there are two locking arms, the difficulty of removing the protective cover from the mounting base is further reduced, thereby improving the operator's maintenance efficiency. Furthermore, since there are at least 2N locking slots, and N≥2, it ensures that wire harnesses located outside the rectifier cabinet housing can be connected to the first end of the conductive post from multiple directions, ensuring the flexibility of connecting wire harnesses outside the rectifier cabinet housing to the conductive post.

[0020] Optionally, the mounting base is provided with at least two metal bushings spaced apart along its circumference, the metal bushings having through holes for screws to pass through.

[0021] By adopting the above technical solution, when installing the mounting base onto the rectifier cabinet housing, the inner end face of the mounting base is first placed against the rectifier cabinet housing. Then, screws for fixing the mounting base are inserted into the through holes of the metal bushings, and the screw threads are threaded into the rectifier cabinet housing to secure the mounting base. The metal bushings increase the connection stability between the mounting base and the rectifier cabinet housing, preventing situations where poor rigidity of the mounting base affects the connection stability. Since at least two metal bushings are spaced apart, the number of connection points between the mounting base and the rectifier cabinet housing is increased, thereby enhancing the connection stability.

[0022] Optionally, the outer end face is provided with a partition groove extending circumferentially along the conductive post, the partition groove being located between the conductive post and the metal bushing.

[0023] By adopting the above technical solution, since the partition groove extends circumferentially along the conductive post and is located between the conductive post and the metal bushing, the creepage distance between the conductive post and the metal bushing is increased, thereby improving the safety of the connector.

[0024] Optionally, the inner end face is provided with a boss that is sleeved on the outside of the conductive post, and the boss is provided with an isolation groove that extends circumferentially along the conductive post, and the isolation groove is located between the conductive post and the metal bushing.

[0025] By adopting the above technical solution, since the boss is sleeved on the outside of the conductive post, the connection area between the conductive post and the mounting base is increased, thereby increasing the connection stability between the conductive post and the mounting base; and since the isolation groove extends along the circumference of the conductive post and is located between the conductive post and the metal bushing, the creepage distance between the conductive post and the metal bushing is increased, thereby further improving the safety of the connector.

[0026] Optionally, the outer end face is provided with a plurality of positioning ribs at intervals. The positioning ribs are located on the side of the connection position and can extend into the protective cover and abut against the inner wall of the protective cover.

[0027] By adopting the above technical solution, after the protective cover is installed onto the mounting base, the positioning rib is located inside the dust cover and abuts against the inner wall of the dust cover. The cooperation between the positioning rib and the inner wall of the dust cover allows for positioning and guiding of the protective cover. This facilitates installation and increases the stability of the connection between the protective cover and the mounting base. Because the positioning rib is located on the side of the connection point, it avoids contact with the connecting parts, ensuring easy removal of the protective cover from the mounting base.

[0028] Optionally, the positioning rib is located inside the metal bushing, and the protective cover has a recessed portion facing inward, with the positioning rib abutting against the inner wall of the recessed portion.

[0029] By adopting the above technical solution, since the positioning rib is located inside the metal bushing, the positioning rib and the metal bushing are integrated into the same position of the mounting base. This facilitates the miniaturization of the connector and also increases the creepage distance between the conductive post and the metal bushing, thereby further enhancing the connector's safety. The recessed portion ensures that the positioning rib abuts against the protective cover after it is installed in the mounting base, and also increases the structural strength of the protective cover, ensuring its protective effect and extending its service life.

[0030] Optionally, the passage includes a first notch and a second notch communicating with the first notch. The second notch is located on the side of the first notch away from the mounting base. A first sealing piece is provided in the first notch, and a second sealing piece is provided in the second notch. Both the first sealing piece and the second sealing piece are fixedly connected to the protective cover by ribs.

[0031] By adopting the above technical solution, if the diameter of the wire harness located outside the rectifier cabinet housing is small, the first sealing piece is removed from the protective cover so that the wire harness located outside the rectifier cabinet housing can be located in the first notch; if the diameter of the wire harness located outside the rectifier cabinet housing is large, both the first and second sealing pieces are removed from the protective cover so that the wire harness located outside the rectifier cabinet housing can be located in the first and second notches. By setting the passage as the first and second notches, and setting the first sealing piece in the first notch and the second sealing piece in the second notch, it is possible to select whether to remove the first sealing piece or both the first and second sealing pieces according to the diameter of the wire harness located outside the rectifier cabinet housing. This avoids the situation where the area of ​​the passage is large due to the large diameter of the wire harness, which would allow the operator's fingers to be inserted into the protective cover through the passage, thereby improving the protective effect of the protective cover and further improving the safety of the connector.

[0032] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0033] 1. The connector in this application includes a mounting base, conductive posts, and a protective cover. The mounting base has an outer end face and an inner end face. The conductive posts are disposed on the mounting base and have a first end and a second end. The protective cover has a through-hole for the wire harness to pass through. The protective cover is disposed on the outer end face and can cover the outside of the first end. One of the outer end face and the protective cover has a plurality of connection positions evenly spaced along its circumference. The other of the two has a plurality of connectors evenly spaced along its circumference that can connect and mate with the connection positions. The connectors are arranged corresponding to the connection positions so that when any connector is connected and mates with one of the connection positions, the remaining... All remaining connectors can be connected to their corresponding connection positions, allowing operators to adjust the protective cover according to the location of the wire harness. This ensures that the wire harness is positioned within the passage after the protective cover is installed on the mounting base, thus freeing the wire harness installation position from the limitations imposed by the relative positions of the protective cover and the mounting base. This increases the possibility of installing the wire harness at the first end of the conductive post in multiple directions, thereby avoiding the limitation of wire harness layout outside the rectifier cabinet housing. This improves the space utilization outside the rectifier cabinet housing and makes the wire harness layout more organized, facilitating future maintenance.

[0034] 2. The protective cover in this application has a clearance notch on its side, and the connector is a snap-fit ​​arm located in the clearance notch. The snap-fit ​​arm can engage with the connection position. When installing the protective cover, first align the port with the wire harness connected to the first end, and simultaneously align the snap-fit ​​arm with the connection position. Then, apply a pushing force to the protective cover in the direction of the mounting base to move the protective cover closer to the mounting base. Finally, the snap-fit ​​arm engages with the connection position to complete the installation of the protective cover to the mounting base. This reduces the difficulty of installing the protective cover and improves the installation efficiency.

[0035] 3. The connection position in this application is a snap-fit ​​groove located on the outer end face. The snap-fit ​​groove has a fixed end fixedly connected to the protective cover and a free end opposite to the fixed end. The free end protrudes from the end face of the protective cover, and a snap-fit ​​protrusion is provided on the outer side of the free end. The free end can extend into the snap-fit ​​groove so that the snap-fit ​​protrusion engages with the groove wall of the snap-fit ​​groove. When installing the protective cover, first align the through port with the wire harness connected to the first end, and simultaneously align the snap-fit ​​arm with the snap-fit ​​groove. Then, apply a pushing force to the protective cover in the direction of the mounting base so that the protective cover moves toward the mounting base. Finally, the free end of the snap-fit ​​arm extends into the snap-fit ​​groove, and the snap-fit ​​protrusion engages with the groove wall of the snap-fit ​​groove to complete the installation of the protective cover. This facilitates the installation of the protective cover and also increases the connection stability between the protective cover and the mounting base. Attached Figure Description

[0046] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0047] Many specific details are set forth in the following description in order to provide a full understanding of this application.

[0050] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.

[0051] Reference Figures 1 to 7 This application discloses a connector for a charging pile rectifier cabinet, which includes a mounting base 1, a conductive post 2, and a protective cover 3. The mounting base 1 has an outer end face 11 and an inner end face 12 opposite to the outer end face 11. The conductive post 2 is disposed on the mounting base 1 and has a first end protruding from the outer end face 11 and a second end protruding from the inner end face 12. The protective cover 3 is provided with a through-hole 31 for the wire harness to pass through. The protective cover 3 is disposed on the outer end face 11 and can cover the outside of the first end. One of the outer end face 11 and the protective cover 3 is provided with a plurality of connection positions evenly spaced along its circumference. The other of the two is provided with a plurality of connectors that can be connected and cooperate with the connection positions evenly spaced along its circumference. The connectors are arranged corresponding to the connection positions so that when any connector is connected and cooperated with one of the connection positions, the remaining connectors can be connected to their corresponding connection positions.

[0052] It is understandable that the conductive post 2 is fixedly connected to the mounting base 1 to ensure the stability of the connection between the conductive post 2 and the mounting base 1.

[0053] It should be noted that the mounting base 1 and the protective cover 3 are made of non-conductive materials, such as hard plastic; the conductive post 2 is made of conductive materials, such as copper.

[0054] When using the connector in this application, first connect the second end of the conductive post 2 to the wire harness, then fix the wire harness to the copper busbar of the rectifier unit, then fix the mounting base 1 to the housing of the rectifier cabinet so that the inner end face 12 abuts against the housing of the rectifier cabinet, then connect the wire harness outside the housing of the rectifier cabinet to the first end of the conductive post 2, and then install the protective cover to the mounting base 1 so that the connector is connected to the connection position, while the wire harness is located in the through port 31 to complete the installation of the connector.

[0055] Because one of the outer end face 11 and the protective cover 3 is provided with multiple connection positions evenly spaced along its circumference, and the other of the two is provided with multiple connectors that can connect and cooperate with the connection positions evenly spaced along its circumference, and the connectors are provided corresponding to the connection positions, the staff can adjust the protective cover 3 according to the position of the wire harness so that the wire harness is located in the passage 31 after the protective cover 3 is installed on the mounting base 1. This makes the installation position of the wire harness no longer limited by the relative position of the protective cover 3 and the mounting base 1, thereby increasing the number of directions in which the wire harness can be installed on the first end of the conductive post 2. This avoids the situation where the wire harness layout outside the rectifier cabinet housing is restricted, thereby improving the space utilization rate outside the rectifier cabinet housing and making the wire harness layout more regular, so as to facilitate the later maintenance.

[0056] Preferably, the conductive post 2 and the mounting base 1 are coaxially arranged. When producing the mounting base 1, the conductive post 2 is first placed in the mold, and then the fluid material is poured into the mold so that the fluid material solidifies and forms the mounting base 1 in the mold, thereby achieving a fixed connection between the conductive post 2 and the mounting base 1, which increases the connection stability between the conductive post 2 and the mounting base 1.

[0057] This application does not specify a particular connection method between the connector and the connection position, which can be any of the following methods:

[0058] Implementation Method 1, in this implementation method, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The protective cover 3 has a clearance notch 32 on its side. The connector is a snap-fit ​​arm 4 located in the clearance notch 32. The snap-fit ​​arm 4 can snap into the connection position. In other words, the protective cover 3 is connected to the mounting base 1 by snap-fit.

[0059] Specifically, when installing the protective cover 3, first align the port 31 with the wire harness connected to the first end, and simultaneously align the snap-fit ​​arm 4 with the connection position. Then, apply a pushing force to the protective cover 3 in the direction of the mounting base 1, so that the protective cover 3 moves towards the mounting base 1. Finally, the snap-fit ​​arm 4 and the connection position snap together to complete the installation of the protective cover 3 onto the mounting base 1. This reduces the difficulty of installing the protective cover 3 and improves the installation efficiency.

[0060] When removing the protective cover 3 from the mounting base 1, press the snap-fit ​​arm 4 to separate the snap-fit ​​arm 4 from the connection position, and then apply a pulling force to the protective cover 3 away from the mounting base 1 to separate the protective cover 3 from the mounting base 1. In this process, it is only necessary to press the snap-fit ​​arm 4 and apply a pulling force to the protective cover 3 away from the mounting base 1, thereby achieving the effect of facilitating the disassembly of the protective cover 3.

[0061] Preferably, the outer side of the snap-fit ​​arm 4 is provided with multiple anti-slip ribs to prevent the worker's hand from slipping on the snap-fit ​​arm 4 when pressing it, thereby improving the worker's pressing experience.

[0062] This application does not impose specific limitations on the structure of the connection bits, which can adopt any of the following embodiments:

[0063] Example 1, in this example, refers to Figures 1 to 4 The connection position is a snap-fit ​​groove 13 located on the outer end face 11. The snap-fit ​​arm 4 has a fixed end that is fixedly connected to the protective cover 3 and a free end opposite to the fixed end. The free end protrudes from the end face of the protective cover 3, and a snap-fit ​​protrusion 41 is provided on the outer side of the free end. The free end can extend into the snap-fit ​​groove 13 so that the snap-fit ​​protrusion 41 engages with the groove wall of the snap-fit ​​groove 13.

[0064] It is understandable that the snap-fit ​​groove 13 forms a connection position. The snap-fit ​​groove 13 extends from the outer end face 11 to the inner end face 12, and the free end protrudes from the end face of the protective cover 3 facing the mounting base 1.

[0065] Specifically, when installing the protective cover 3, first align the through port 31 with the wire harness connected to the first end, and simultaneously align the snap-fit ​​arm 4 with the snap-fit ​​groove 13. Then, apply a pushing force to the protective cover 3 in the direction of the mounting base 1, so that the protective cover 3 moves toward the mounting base 1. Finally, the free end of the snap-fit ​​arm 4 extends into the snap-fit ​​groove 13, and the snap-fit ​​protrusion 41 snaps together with the groove wall of the snap-fit ​​groove 13 to complete the installation of the protective cover 3. This facilitates the installation of the protective cover 3 and also increases the connection stability between the protective cover 3 and the mounting base 1.

[0066] The better one is to refer to Figure 1 and Figure 2 The snap-fit ​​groove 13 penetrates the side of the mounting base 1 to reduce the molding difficulty of the mounting base 1, increase the yield of the mounting base 1, and reduce the production cost of the mounting base 1.

[0067] Preferably, a guide surface is provided on the outer side of the snap-fit ​​protrusion 41. The guide surface is inclined from the free end toward the fixed end toward the direction away from the protective cover 3, so that the guide surface can guide the snap-fit ​​protrusion 41, thereby reducing the difficulty of inserting the snap-fit ​​protrusion 41 into the snap-fit ​​groove 13 and improving the assembly efficiency of the protective cover 3.

[0068] Furthermore, refer to Figure 5 and Figure 6 There are two card arms 4 respectively, and at least 2N card slots 13 are provided, where N satisfies: N≥2.

[0069] Specifically, when removing the protective cover 3 from the mounting base 1, the operator simultaneously presses down on both locking arms 4 with their fingers, causing the two locking arms 4 to move towards each other, thereby separating the locking protrusion 41 from the groove wall of the locking groove 13. Then, a pulling force is applied to the protective cover 3 away from the mounting base 1, causing the locking arms 4 to disengage from the locking groove 13, thus completing the removal of the protective cover 3 from the mounting base 1. Since there are two locking arms 4 arranged opposite each other, the difficulty for the operator in removing the protective cover 3 from the mounting base 1 is further reduced, thereby improving the operator's maintenance efficiency.

[0070] Furthermore, since the snap-fit ​​slots 13 are provided with at least 2N slots, and N≥2, it is ensured that the wire harness located outside the rectifier cabinet housing can be connected to the first end of the conductive post 2 from multiple directions, thereby ensuring the flexibility of the wire harness located outside the rectifier cabinet housing to be connected to the conductive post 2.

[0071] Specifically, the projection of the protective cover toward the mounting base 1 is a square, the projection of the outer end face 11 of the mounting base 1 toward the inner end face 12 is a square, there are two snap-fit ​​arms 4, which are located on opposite sides of the protective cover 3, and there are four snap-fit ​​slots 13, which are respectively located on the four sides of the mounting base 1, so that the wire harness located outside the rectifier cabinet housing can be installed to the first end of the conductive post 2 in at least four directions.

[0072] Of course, in other implementation examples, the protective cover and the mounting base 1 can also be projected as a circle, a regular pentagon, a regular hexagon, etc., and the number of snap-fit ​​slots 13 is equal to the number of sides of the mounting base 1, so as to further increase the flexibility of the wiring harness installation direction.

[0073] In other embodiments, the connection point may also be a snap-fit ​​block provided on the outer end face 11, which can engage with the snap-fit ​​protrusion 41.

[0074] Of course, the positions of the snap-fit ​​arm 4 and the snap-fit ​​groove 13 can also be interchanged. That is, the snap-fit ​​arm 4 can be placed on the mounting base 1, and the snap-fit ​​groove 13 can be placed on the protective cover 3.

[0075] In the second embodiment, the protective cover 3 has an edge at one end near the mounting base 1, the connecting member is a bolt passing through the edge, and the connecting position is a threaded hole on the inner end face 12. The bolt can be threaded into the threaded hole so as to fix the protective cover 3 to the mounting base 1 using the bolt.

[0076] In a preferred embodiment, refer to Figure 6 and Figure 7 The mounting base 1 is provided with at least two metal bushings 14 spaced apart along its circumference, and the metal bushings 14 have through holes for screws to pass through.

[0077] Specifically, when installing the mounting base 1 to the rectifier cabinet housing, the inner end face 12 of the mounting base 1 is first pressed against the rectifier cabinet housing. Then, screws for fixing the mounting base 1 are inserted into the through holes of the metal bushing 14, and the screw threads are threaded into the rectifier cabinet housing to fix the mounting base 1. By setting the metal bushing 14, the connection stability between the mounting base 1 and the rectifier cabinet housing is increased, thus avoiding the situation where the poor rigidity of the mounting base 1 affects the connection stability between the mounting base 1 and the rectifier cabinet housing. Since at least two metal bushings 14 are provided at intervals, the number of connection points between the mounting base 1 and the rectifier cabinet housing is increased, thereby increasing the connection stability between the mounting base 1 and the rectifier cabinet housing.

[0078] The better one is to refer to Figure 6 and Figure 7Four metal bushings 14 are provided, and the four metal bushings 14 are respectively located at the four corners of the mounting base 1 to increase the number of connection points where the mounting base 1 can be connected to the mounting base 1 by screws, thereby further increasing the connection stability between the mounting base 1 and the rectifier cabinet housing. When the mounting base 1 is produced, the metal bushings 14 are placed in the mold, and then the fluid material is poured into the mold so that the fluid material solidifies in the mold and forms the mounting base 1. The fluid material solidifies on the outside of the metal bushings 14 to achieve a fixed connection between the metal bushings 14 and the mounting base 1.

[0079] The better one is to refer to Figure 6 The outer end face 11 is recessed near the inner end face 12 at the location where the metal bushing 14 is provided, forming a mounting plane 141, so that after the mounting base 1 is fixedly connected to the rectifier cabinet housing by screws, the screw head can avoid the protective cover 3.

[0080] This application does not specify the material of the metal bushing 14. Preferably, the metal bushing 14 is made of steel to further increase the stability of the connection between the mounting base 1 and the rectifier cabinet housing via screws. Of course, in other embodiments, the metal bushing 14 can also be made of materials such as iron or aluminum.

[0081] Furthermore, refer to Figure 3 , Figure 4 and Figure 6 The outer end face 11 is provided with a partition groove 111 extending circumferentially along the conductive post 2. The partition groove 111 is located between the conductive post 2 and the metal bushing 14, thereby increasing the creepage distance between the conductive post 2 and the metal bushing 14, and thus improving the safety of the connector.

[0082] It should be noted that creepage distance refers to the shortest distance between two conductive parts measured along the insulating surface.

[0083] Furthermore, refer to Figure 6 The partition groove 111 is provided with reinforcing blocks 112 connected to the two opposite groove walls of the partition groove 111 to ensure the structural strength of the mounting base 1, thereby ensuring the service life of the mounting base 1.

[0084] Furthermore, refer to Figure 3 , Figure 4 and Figure 7 The inner end face 12 is provided with a boss 121 sleeved on the outside of the conductive post 2, thereby increasing the connection area between the conductive post 2 and the mounting base 1, so as to increase the connection stability between the conductive post 2 and the mounting base 1. The boss 121 is provided with an isolation groove 122 extending along the circumference of the conductive post 2. The isolation groove 122 is located between the conductive post 2 and the metal bushing 14, thereby increasing the creepage distance between the conductive post 2 and the metal bushing 14, and further improving the safety of the connector.

[0085] Furthermore, refer to Figure 7 The isolation groove 122 is provided with reinforcing ribs 123 connected to the two opposite groove walls of the isolation groove 122 to ensure the structural strength of the boss 121, thereby ensuring the service life of the mounting base 1.

[0086] Furthermore, refer to Figure 3 , Figure 4 and Figure 6 The outer end face 11 is provided with a plurality of positioning ribs 113 at intervals. The positioning ribs 113 are located on the side of the connection position. The positioning ribs 113 can extend into the protective cover 3 and can abut against the inner wall of the protective cover 3.

[0087] Specifically, after the protective cover 3 is installed onto the mounting base 1, the positioning rib 113 extends into the interior of the dust cover and abuts against the inner wall of the dust cover. This allows the positioning rib 113 to be used to position and guide the protective cover 3, facilitating its installation and increasing the stability of the connection between the protective cover 3 and the mounting base 1. Because the positioning rib 113 is located on the side of the connection point, it avoids contact with the connecting parts, ensuring easy removal of the protective cover 3 from the mounting base 1.

[0088] Preferably, the height of the positioning rib 113 is greater than the length of the free end protruding from the end face of the protective cover 3 toward the mounting base 1, so that the positioning rib 113 can be inserted into the protective cover 3 when the protective cover 3 is first installed, thereby improving the guiding effect of the positioning rib 113 on the protective cover 3.

[0089] Furthermore, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The positioning rib 113 is located inside the metal bushing 14, and the protective cover 3 has a recessed portion 33 recessed towards its own interior, with the positioning rib 113 abutting against the inner wall of the recessed portion 33.

[0090] Since the positioning rib 113 is located inside the metal bushing 14, the positioning rib 113 and the metal bushing 14 are integrated in the same position of the mounting base 1. This facilitates the miniaturization of the connector and increases the creepage distance between the conductive post 2 and the metal bushing 14, thereby further enhancing the connector's safety. The recessed portion 33 ensures that the positioning rib 113 abuts against the protective cover 3 after it is installed in the mounting base 1. It also increases the structural strength of the protective cover 3, ensuring its protective effect and extending its service life.

[0091] Preferably, the shape of the positioning rib 113 is adapted to the shape of the recess 33 to increase the contact area between the positioning rib 113 and the inner wall of the recess 33, thereby increasing the guiding and positioning effect on the protective cover 3.

[0092] In a preferred embodiment, refer to Figure 2 , Figure 3 and Figure 5 The opening 31 includes a first notch 311 and a second notch 312 communicating with the first notch 311. The second notch 312 is located on the side of the first notch 311 away from the mounting base 1. A first sealing piece 313 is provided in the first notch 311, and a second sealing piece 314 is provided in the second notch 312. Both the first sealing piece 313 and the second sealing piece 314 are fixedly connected to the protective cover 3 by a rib 315.

[0093] Understandably, the ribs 315 are spaced in multiples to facilitate the removal of the first sealing piece 313 and the second sealing piece 314 from the protective cover 3.

[0094] It should be noted that when removing the first sealing piece 313 or the second sealing piece 314 from the protective cover 3, a force is applied to the first sealing piece 313 or the second sealing piece 314 in the direction of the inside or outside of the protective cover 3, so that the first sealing piece 313 or the second sealing piece 314 pulls on the rib 315, eventually causing the rib 315 to break, so as to remove the first sealing piece 313 or the second sealing piece 314 from the protective cover 3.

[0095] If the diameter of the wire harness located outside the rectifier cabinet housing is small, the first sealing piece 313 is removed from the protective cover 3 so that the wire harness located outside the rectifier cabinet housing can be located in the first notch 311; if the diameter of the wire harness located outside the rectifier cabinet housing is large, both the first sealing piece 313 and the second sealing piece 314 are removed from the protective cover 3 so that the wire harness located outside the rectifier cabinet housing can be located in the first notch 311 and the second notch 312.

[0096] By setting the passage 31 as a first notch 311 and a second notch 312, and setting a first sealing piece 313 in the first notch 311 and a second sealing piece 314 in the second notch 312, it is possible to select whether to remove the first sealing piece 313 or both the first sealing piece 313 and the second sealing piece 314 according to the diameter of the wire harness located outside the rectifier cabinet housing. This avoids the situation where the area of ​​the passage 31 is large due to the large diameter of the wire harness, which would allow the operator's fingers to be inserted into the protective cover 3 through the passage 31. This improves the protective effect of the protective cover 3 and further enhances the safety of the connector.

[0097] The better one is to refer to Figure 2 and Figure 5 The width of the first notch 311 is greater than the width of the second notch 312, so as to increase the space for the wire harness to be accommodated on the side of the protective cover 3 near the mounting base 1, making the installation direction of the wire harness more flexible.

[0098] In a preferred embodiment, refer to Figure 1 , Figure 2 and Figure 6 The first protective cover 3 has an identification area 34 on the end face opposite to the mounting base 1. The identification area 34 can be integrally formed, engraved, or pasted with prompts or manufacturer information, such as "+" or "-" integrally formed in the identification area 34, so that staff can distinguish the connectors.

[0099] In a preferred embodiment, refer to Figure 3 The first end is provided with a threaded hole for bolt thread connection so that the wire harness connected to the first end can be fixed by bolt.

[0100] In a preferred embodiment, refer to Figure 3 The second end is provided with a rivet nut 21 on its side so that the wire harness connected to the second end can also be fixed by the bolts threaded to the rivet nut 21.

[0101] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0102] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
