Description

Technical Field

[0001] This application belongs to the technical field of connectors, specifically relating to a split 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] In related technologies, connectors include a base and conductive posts disposed on the base. The conductive posts are made of conductive materials, such as copper or aluminum, while the base is made of insulating materials, such as rigid plastic. When using the connector, one end of the conductive post is crimped with a conductive wire harness and then fixedly connected to the copper busbar of the rectifier unit. It is then installed on the rectifier cabinet's outer casing, and the other end, located outside the casing, is connected to the wire harness located outside the casing. To improve the connection stability between the conductive post and the base, insert injection molding is commonly used to produce connectors. In this process, the conductive post is first placed in a mold, and then fluid plastic is poured into the mold, allowing it to solidify and form the base, which then solidifies on the outside of the conductive post. While this improves the connection stability, it also increases the manufacturing difficulty of the connector, thus increasing production costs. Furthermore, if either the base or the conductive post is damaged, the entire connector needs to be replaced, resulting in higher operating costs. Utility Model Content

[0004] This application provides a split connector for a charging pile rectifier cabinet to reduce the difficulty, cost, and usage cost of connector production.

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

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

[0007] The base body has mounting holes;

[0008] A conductive component is provided in the mounting hole along a first direction. The conductive component includes a first connecting section and a second connecting section arranged at an angle to the first connecting section. The second connecting section can cooperate with the seat stop in the first direction. The first connecting section is provided with a stop portion that can cooperate with the seat stop in a second direction. The second direction is opposite to the first direction. The first connecting section is provided with a press-fit nut. The second connecting section is provided with a through hole for a bolt to pass through.

[0009] A connecting block having a threaded hole for bolt thread connection, the central axis of the threaded hole being collinear with the central axis of the through hole, the connecting block being located between the second connecting section and the seat body, so that the connecting block is fixed to the seat body by the compression of the second connecting section.

[0010] By adopting the above technical solution, when using the split connector in this application, the wire harness used to connect to the first connecting section is first fixed to the first connecting section by the threaded engagement of the bolt and the rivet nut, and then the base is fixed, and then the wire harness used to connect to the second connecting section is fixed by the bolt. That is, the bolt is passed through the through hole and threaded into the threaded hole, so as to use the compression of the wire harness terminal by the bolt head to fix the wire harness to the second connecting section.

[0011] Because the conductive element in this application is fixedly connected to the base body by the second connecting section engaging with the stop of the base body in the first direction and the stop engaging with the base body in the second direction, the conductive element and the base body can be separately installed. In other words, the method of fixed connection using insert injection molding as in the prior art is avoided, thereby reducing the manufacturing difficulty of the connector, reducing the production cost of the connector, and increasing the yield of the connector. Furthermore, when either the base body or the conductive element is damaged, the damaged part can be replaced separately, thereby reducing the use cost of the connector. In addition, the conductive element can be formed by stamping and bending a sheet structure, which also reduces the manufacturing difficulty and cost of the conductive element.

[0012] Optionally, the second connecting segment is arranged perpendicularly to the first connecting segment, and the conductive element further includes an inclined segment, one end of which is connected to one end of the first connecting segment, and the other end of which is connected to one end of the second connecting segment.

[0013] By adopting the above technical solution, since the first connecting segment and the second connecting segment are set perpendicularly, the first connecting segment can be set parallel to the axial direction of the base body, and the second connecting segment can be set parallel to the end face of the base body, so as to facilitate the connection of the wire harness with the first connecting segment and the second connecting segment. In addition, since the two ends of the inclined segment are respectively connected to one end of the first connecting segment and one end of the second connecting segment, the central axis of the through hole can be set collinearly with the central axis of the base body, and the first connecting segment is located in the central area of ​​the base body, so that the distance of the through hole from each side of the base body is equal, and it is very convenient to connect the wire harness with the second connecting segment in all directions.

[0014] Optionally, the base has a first end face and a second end face opposite to the first end face, the second end face being provided with a mounting cavity communicating with the mounting hole, the connecting block being located in the mounting cavity, and at least a portion of the second connecting segment being located in the mounting cavity.

[0015] By adopting the above technical solution, since the connecting block is located in the mounting cavity, the stability of the connecting block is increased, thereby ensuring the stability of the connection between the wire harness and the connecting block through the bolt, and thus ensuring the electrical conductivity stability between the wire harness and the first connecting segment; since at least part of the second connecting segment is located in the mounting cavity, the cavity wall of the mounting cavity can limit the side of the second connecting segment, thereby increasing the stability of the second connecting segment.

[0016] Optionally, the inclined segment is provided with a positioning notch, the positioning notch and the second connecting segment are both located on the same side of the inclined segment, and at least a portion of the connecting block is located in the positioning notch.

[0017] By adopting the above technical solution, since at least part of the connecting block is located in the positioning notch, the inclined section can support the connecting block to increase the stability of the connecting block, so as to ensure that the bolts are easily threaded together with the connecting block, thereby reducing the difficulty of connecting the wire harness and the connector together.

[0018] Optionally, the inclined section is provided with a clearance hole corresponding to the threaded hole, and the clearance hole is located below the connecting block.

[0019] By adopting the above technical solution, since the clearance hole is set corresponding to the threaded hole and located below the connecting block, the bolt that is threaded to the threaded hole can be inserted into the clearance hole so that the inclined section and the bolt can avoid each other, thereby ensuring that the bolt can be threaded into the connecting block to a certain depth, and thus ensuring the electrical connection stability between the wire harness and the connector.

[0020] Optionally, the stop portion is a stop block provided on the side of the first connecting section, and the stop block can cooperate with the seat body to stop in a second direction.

[0021] By adopting the above technical solution, since the stop part is a stop block located on the side of the first connecting section, the stop block can be used to stop the seat body and the second connecting section can be used to stop the conductive component to the seat body, thereby ensuring the connection stability between the conductive component and the seat body.

[0022] Optionally, the mounting hole has a clearance notch in its wall, and a stop arm is provided in the clearance notch. The stop arm has an upper end fixedly connected to the wall of the clearance notch and a lower end opposite to the upper end. The lower end can swing around the upper end, and the stop block can cooperate with the lower end stop.

[0023] By adopting the above technical solution, when installing the conductive component onto the base, the first connecting segment is first aligned with the mounting hole. Then, a thrust parallel to the first direction is applied to the conductive component, causing it to move along the first direction. This allows the first connecting segment to extend into the mounting hole. As the depth of the first connecting segment into the mounting hole increases, the stop block abuts against the stop arm and applies pressure to the stop arm, causing the stop arm to deform. Ultimately, the stop block passes over the stop arm, and then the stop arm returns to its original shape and engages with the stop block, thus completing the installation of the conductive component onto the base. During the installation of the conductive component, only a thrust along the first direction needs to be applied, thereby reducing the difficulty of installation and improving the installation efficiency.

[0024] Optionally, at least two metal rings are provided at intervals along the edge of the seat, and the metal rings have a central hole.

[0025] By adopting the above technical solution, when fixing the connector, screws or bolts are used to pass through the central hole and are threaded together with the components used to install the connector to achieve the fixing of the connector. By setting a metal ring, the structural strength of the seat where screws or threads need to be passed through can be increased to ensure the fixing stability of the connector.

[0026] Optionally, the seat has a first end face and a second end face opposite to the first end face. The second end face is provided with an annular groove, which extends circumferentially along the second connecting segment and is located between the metal ring and the second connecting segment.

[0027] By adopting the above technical solution, since the annular groove extends circumferentially along the second connecting section and is located between the metal ring sleeve and the second connecting section, the creepage distance between the second connecting section and the metal ring sleeve is increased, thereby increasing the safety of the connector and ensuring the service life of the connector.

[0028] Optionally, the first end face is provided with a boss sleeved on the outside of the conductive element, the boss is provided with a partition groove, the partition groove extends circumferentially along the first connecting segment, and the partition groove is located between the metal ring and the first connecting segment.

[0029] By adopting the above technical solution, since the boss is sleeved on the outside of the conductive component, the contact area between the conductive component and the base is increased, thereby increasing the connection stability between the conductive component and the base; and since the partition groove extends circumferentially along the first connecting section and is located between the metal ring and the first connecting section, the creepage distance between the metal ring and the first connecting section is increased, thereby increasing the safety of the connector and ensuring the service life of the connector.

[0030] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0031] 1. A split connector includes a base, a conductive element, and a connecting block. The base has a mounting hole, and the conductive element passes through the mounting hole along a first direction. The conductive element includes a first connecting section and a second connecting section arranged at an angle to the first connecting section. The second connecting section can engage with a stop on the base in the first direction. The first connecting section is provided with a stop portion that can engage with the stop on the base in a second direction. The second direction is opposite to the first direction. The first connecting section is provided with a press-fit nut, and the second connecting section is provided with a through hole for a bolt to pass through. The connecting block has a threaded hole for a bolt threaded connection. The central axis of the threaded hole is collinear with the central axis of the through hole. The connecting block is located between the second connecting section and the base. The connection is designed to be fixed to the base by the compression of the second connecting section, allowing the conductive component and the base to be separated. This avoids the use of insert injection molding in existing technologies to achieve a fixed connection, thereby reducing the manufacturing difficulty of the connector, lowering the production cost, and increasing the yield rate. Furthermore, if either the base or the conductive component is damaged, the damaged part can be replaced separately, further reducing the cost of using the connector. Additionally, the conductive component can be formed by stamping and bending a sheet structure, which also reduces the manufacturing difficulty and cost of the conductive component.

[0032] 2. In this application, the second connecting segment is perpendicular to the first connecting segment, thereby enabling the first connecting segment to be parallel to the axial direction of the base body and the second connecting segment to be parallel to the end face of the base body, so as to facilitate the connection of the wire harness with the first connecting segment and the second connecting segment; the conductive component also includes an inclined segment, one end of which is connected to one end of the first connecting segment and the other end of which is connected to one end of the second connecting segment, so that the central axis of the through hole can be collinear with the central axis of the base body, and the first connecting segment is located in the central area of ​​the base body, so that the distance between the through hole and each side of the base body is equal, and thus it is very convenient to connect the wire harness with the second connecting segment in all directions.

[0033] 3. The base in this application has a first end face and a second end face. The second end face is provided with a mounting cavity communicating with the mounting hole. The connecting block is located in the mounting cavity, and at least a portion of the second connecting segment is located in the mounting cavity, thereby increasing the stability of the connecting block to ensure the stability of the connection between the wire harness and the connecting block through the bolt, thereby ensuring the electrical conductivity stability between the wire harness and the first connecting segment. Since at least a portion of the second connecting segment is located in the mounting cavity, the cavity wall of the mounting cavity can limit the side of the second connecting segment to increase the stability of the second connecting segment.

[0051] Reference Figures 1 to 9 A split connector for a charging pile rectifier cabinet is disclosed, comprising a base 1, a conductive element 2, and a connecting block 3. The base 1 has a mounting hole 11. The conductive element 2 passes through the mounting hole 11 along a first direction. The conductive element 2 includes a first connecting section 21 and a second connecting section 22 arranged at an angle to the first connecting section 21. The second connecting section 22 can cooperate with the base 1 in the first direction. The first connecting section 21 is provided with a stop part 212 that can cooperate with the base 1 in the second direction. The second direction is opposite to the first direction. The first connecting section 21 is provided with a press-fit nut 211. The second connecting section 22 is provided with a through hole 221 for bolts to pass through. The connecting block 3 has a threaded hole for bolt thread connection. The central axis of the threaded hole is collinear with the central axis of the through hole 221. The connecting block 3 is located between the second connecting section 22 and the base 1 so that the connecting block 3 is fixed to the base 1 by the compression of the second connecting section 22.

[0052] It should be noted that the mounting hole 11 passes through the seat body 1 in the axial direction; since the connecting block 3 is located between the second connecting section 22 and the seat body 1, the second connecting section 22 is stopped and engaged with the seat body 1 in the first direction through the connecting block 3. That is to say, when the second connecting section 22 abuts against the connecting block 3 and the connecting block 3 abuts against the seat body 1, the conductive element 2 cannot move relative to the seat body 1 in the first direction; after the conductive element 2 is installed on the seat body 1, the stop part 212 is engaged with the bottom stop of the seat body 1, thereby preventing the conductive element 2 from moving relative to the seat body 1 in the second direction.

[0053] It is understandable that the base 1 is made of a non-conductive material, such as rigid plastic, to ensure the structural strength of the base 1, while the conductive component 2 is made of a conductive material, such as copper, to ensure the conductivity of the conductive component 2.

[0054] When assembling the connector, the conductive element 2, the base 1, and the connecting block 3 are first formed separately. Then, the connecting block 3 is attached to the conductive element 2. Next, the first connecting segment 21 of the conductive element 2 is aligned with the mounting hole 11. Then, a pushing force along the first direction is applied to the conductive element 2, which causes the conductive element 2 to move along the first direction. The first connecting segment 21 passes through the mounting hole 11, and finally the connecting block 3 abuts against the base 1. The stop part 212 contacts the base 1 and stops and engages, thereby completing the assembly of the connector.

[0055] When using the split connector in this application, the wire harness used to connect to the first connecting section 21 is first fixed to the first connecting section 21 by the threaded engagement of the bolt and the rivet nut 211. Then the base 1 is fixed, and the wire harness used to connect to the second connecting section 22 is fixed by the bolt. That is, the bolt is passed through the through hole 221 and threaded into the threaded hole, so that the wire harness is fixedly connected to the second connecting section 22 by the compression of the wire harness terminal by the bolt head.

[0056] Since the conductive element 2 in this application is fixedly connected to the base 1 by the second connecting section 22 engaging with the stop of the base 1 in the first direction and the stop part 212 engaging with the base 1 in the second direction, the conductive element 2 and the base 1 can be separately installed. In other words, the fixed connection method of using insert injection molding as in the prior art is avoided, thereby reducing the manufacturing difficulty of the connector, reducing the manufacturing cost of the connector and increasing the yield of the connector. Furthermore, when either the base 1 or the conductive element 2 is damaged, the damaged part can be replaced separately, thereby reducing the use cost of the connector. In addition, the conductive element 2 can be formed by stamping and bending a sheet structure, which also reduces the manufacturing difficulty and manufacturing cost of the conductive element 2.

[0057] In a preferred embodiment, refer to Figure 2 and Figure 4 The second connecting segment 22 is perpendicular to the first connecting segment 21. The conductive component 2 also includes an inclined segment 23, one end of which is connected to one end of the first connecting segment 21, and the other end of which is connected to one end of the second connecting segment 22.

[0058] It is understandable that the mounting hole 11 is provided corresponding to the first connecting section 21 and the inclined section 23, thereby enabling the inclined section 23 to be located in the mounting hole 11.

[0059] Since the first connecting segment 21 and the second connecting segment 22 are arranged perpendicularly, the first connecting segment 21 can be arranged parallel to the axial direction of the base 1, and the second connecting segment 22 can be arranged parallel to the end face of the base 1, so as to facilitate the connection of the wire harness with the first connecting segment 21 and the second connecting segment 22. In addition, since the two ends of the inclined segment 23 are respectively connected to one end of the first connecting segment 21 and one end of the second connecting segment 22, the central axis of the through hole 221 can be arranged collinearly with the central axis of the base 1, and the first connecting segment 21 is located in the central area of ​​the base 1, so that the distance of the through hole 221 from each side of the base 1 is equal, and it is very convenient to connect the wire harness with the second connecting segment 22 in all directions.

[0060] Of course, in other embodiments, the second connecting segment 22 may also be set at other angles with the first connecting segment 21, such as 60°, 80°, etc.

[0061] Furthermore, refer to Figure 3 and Figure 6 The base 1 has a first end face 12 and a second end face 13 opposite to the first end face 12. The second end face 13 is provided with a mounting cavity 111 communicating with the mounting hole 11. The connecting block 3 is located in the mounting cavity 111, and at least a portion of the second connecting section 22 is located in the mounting cavity 111.

[0062] Since the connecting block 3 is located in the mounting cavity 111, the stability of the connecting block 3 is increased to ensure the stability of the connection between the wire harness and the connecting block 3 through the bolt, thereby ensuring the electrical conductivity stability between the wire harness and the first connecting segment 21; since at least a portion of the second connecting segment 22 is located in the mounting cavity 111, the cavity wall of the mounting cavity 111 can limit the side of the second connecting segment 22 to increase the stability of the second connecting segment 22.

[0063] Furthermore, refer to Figure 2 and Figure 4The inclined section 23 is provided with a positioning notch 231. The positioning notch 231 and the second connecting section 22 are both located on the same side of the inclined section 23. At least a part of the connecting block 3 is located in the positioning notch 231. It can be understood that the positioning notch 231 has a support surface located at the bottom of the connecting block 3 so that the positioning notch 231 can support one side of the connecting block 3, while the bottom cavity wall of the mounting cavity 111 supports the other side of the connecting block 3 to increase the stability of the connecting block 3, so as to ensure the effect of easy thread connection of bolts and connecting block 3, thereby reducing the difficulty of connecting wire harness and connector together.

[0064] Furthermore, refer to Figures 2 to 4 The inclined section 23 is provided with a clearance hole 232 corresponding to the threaded hole. The clearance hole 232 is located below the connecting block 3, so that the bolt threaded to the threaded hole can extend into the clearance hole 232, so that the inclined section 23 and the bolt can avoid each other, thereby ensuring that the bolt can be threaded into the connecting block 3 to a certain depth, and thus ensuring the electrical connection stability between the wire harness and the connector.

[0065] This application does not specifically limit the structure of the stop part 212. Preferably, the stop part 212 is a stop block provided on the side of the first connecting section 21, and the stop block can stop and cooperate with the seat 1 in the second direction.

[0066] Since the stop part 212 is a stop block provided on the side of the first connecting section 21, the stop block and the seat 1 can be used to stop and cooperate, and the second connecting section 22 and the seat 1 can be used to fix the conductive element 2 to the seat 1, so as to ensure the connection stability between the conductive element 2 and the seat 1.

[0067] Furthermore, refer to Figures 5 to 7 The mounting hole 11 has a clearance notch 112 on its wall. A stop arm 113 is provided in the clearance notch 112. The stop arm 113 has an upper end fixedly connected to the wall of the clearance notch 112 and a lower end opposite to the upper end. The lower end can swing around the upper end, and the stop block can cooperate with the lower end stop.

[0068] When installing the conductive component 2 onto the base 1, the first connecting segment 21 is first aligned with the mounting hole 11. Then, a pushing force parallel to the first direction is applied to the conductive component 2, causing it to move along the first direction. This allows the first connecting segment 21 to extend into the mounting hole 11. As the depth of the first connecting segment 21 into the mounting hole 11 increases, the stop block abuts against the stop arm 113 and applies pressure to the stop arm 113, causing the stop arm 113 to deform. Eventually, the stop block passes over the stop arm 113, and then the stop arm 113 returns to its original shape and engages with the stop block, thus completing the installation of the conductive component 2 onto the base 1. During the installation of the conductive component 2, only a pushing force along the first direction needs to be applied, thereby reducing the difficulty of installing the conductive component 2 and improving its installation efficiency.

[0069] Preferably, the bottom of the stop block is provided with a guide surface, which is disposed away from the side of the first connecting section 21, and the guide surface is inclined from bottom to top in the direction away from the first connecting section 21, so as to reduce the difficulty of installing the conductive component 2.

[0070] In other embodiments, the stop portion 212 may also be formed by a screw threaded to the first connecting section 21. That is, after the conductive element 2 is inserted into the base 1, the screw is threaded into the first connecting section 21, and the screw abuts against the base 1, so as to achieve a stop engagement between the stop portion 212 and the base 1 in the second direction.

[0071] In a preferred embodiment, refer to Figures 5 to 7 At least two metal rings 14 are provided at intervals along the edge of the base 1, and each metal ring 14 has a central hole.

[0072] Specifically, when fixing the connector, screws or bolts are used to pass through the center hole and are threaded together with the components used to install the connector. For example, screws or bolts are used to pass through the metal ring 14 to fix the base 1 to the outer shell of the rectifier cabinet to fix the connector. By setting the metal ring 14, the structural strength of the base 1 at the location where screws or threads need to be passed through can be increased to ensure the stability of the connector fixing.

[0073] The better one is to refer to Figures 5 to 7 Four metal rings 14 are provided and are located at the four corners of the base 1 respectively, so as to increase the number of fixing points of the base 1 and thus increase the fixing stability of the connector.

[0074] Preferably, the metal ring 14 is connected to the base 1 using an insert injection molding process to increase the connection stability between the two.

[0075] This application does not specify the material for the metal ring 14. Preferably, the metal ring 14 is made of steel to ensure a secure fit to the seat 1. In other embodiments, the metal ring 14 may also be made of other materials with higher hardness.

[0076] Furthermore, refer to Figure 6 The base 1 has a first end face 12 and a second end face 13 opposite to the first end face 12. The second end face 13 is provided with an annular groove 131, which extends circumferentially along the second connecting section 22 and is located between the metal ring sleeve 14 and the second connecting section 22.

[0077] Since the annular groove 131 extends circumferentially along the second connecting section 22 and is located between the metal ring sleeve 14 and the second connecting section 22, the creepage distance between the second connecting section 22 and the metal ring sleeve 14 is increased, thereby increasing the safety of the connector and ensuring the service life of the connector.

[0078] This application does not specify the number of annular grooves 131. Preferably, two annular grooves 131 are provided, with one annular groove 131 located outside the other annular groove 131, to further increase the creepage distance between the second connecting section 22 and the metal ring sleeve 14, thereby further increasing the safety of the connector. Of course, in other embodiments, only one or more annular grooves 131 may be provided.

[0079] Furthermore, refer to Figure 5 and Figure 7 The first end face 12 is provided with a boss 121 sleeved on the outside of the conductive component 2. The boss 121 is provided with a partition groove 122. The partition groove 122 extends circumferentially along the first connecting section 21 and is located between the metal ring 14 and the first connecting section 21.

[0080] Since the boss 121 is sleeved on the outside of the conductive member 2, the contact area between the conductive member 2 and the base 1 is increased, thereby increasing the connection stability between the conductive member 2 and the base 1. Furthermore, since the partition groove 122 extends circumferentially along the first connecting section 21 and is located between the metal ring 14 and the first connecting section 21, the creepage distance between the metal ring 14 and the first connecting section 21 is increased, thereby increasing the safety of the connector and ensuring the service life of the connector.

[0081] This application does not specify the number of partition grooves 122. Preferably, one partition groove 122 is provided to ensure the structural strength of the base 1. In other embodiments, multiple partition grooves 122 may be provided.

[0082] Furthermore, refer to Figure 7A reinforcing rib 123 is provided in the partition groove 122. The two sides of the reinforcing rib 123 are respectively connected to the two opposite groove walls of the partition groove 122 to ensure the structural strength of the seat 1.

[0083] In a preferred embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 The connector also includes a cover 4, which has a through-hole 41 on its side for the wire harness to pass through. The cover 4 is mounted on the second end face 13 of the base 1 so that the cover 4 can cover the outside of the second connecting section 22 to protect the second connecting section 22, thereby preventing the workers' hands from directly contacting the second connecting section 22 and increasing the safety of the connector.

[0084] Understandably, the cover 4 is also made of insulating materials, such as rigid plastic.

[0085] This application does not specifically limit the shape of the cover 4 and the base 1. Preferably, the projection of the cover 4 toward the base 1 is a square, and the projection of the second end face 13 of the base 1 toward the first end face 12 is also a square. Of course, in other embodiments, the shape of the cover 4 and the base 1 can also be a circle, a regular pentagon, a regular hexagon, or other regular polygonal structures.

[0086] Furthermore, refer to Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 The cover 4 has snap-fit ​​arms 42 on opposite sides, and the second end face 13 of the base 1 has snap-fit ​​grooves 15 on all four sides. The two snap-fit ​​arms 42 can snap into any pair of opposite snap-fit ​​grooves 15, thereby allowing the port 41 to be adjusted in four directions. This allows the wire harness to be installed in the second connecting section 22 in four directions, increasing the flexibility of the wire harness installation direction and facilitating the optimization of the wire harness layout.

[0087] Furthermore, refer to Figure 8 and Figure 9 The opening 41 includes a first notch 411 and a second notch 412 located on the side of the first notch 411 away from the seat 1. The width of the first notch 411 is greater than the width of the second notch 412. The cover 4 is provided with a first protective plate 413 located in the first notch 411 and a second protective plate 414 located in the second notch 412. The first protective plate 413 and the second protective plate 414 are both fixedly connected to the cover 4 by ribs.

[0088] It is understandable that multiple ribs are provided at intervals along the circumference of the first protective plate 413 and the second protective plate 414. On the one hand, this increases the stability of the first protective plate 413 and the second protective plate 414. On the other hand, it facilitates the removal of the first protective plate 413 and the second protective plate 414 from the cover body 4.

[0089] When installing the cover 4, first select the first protective plate 413 or the first protective plate 413 and the second protective plate 414 to remove from the cover 4 according to the diameter of the wire harness, and then install the cover 4 onto the base 1 so that there is a small gap between the cover 4 and the wire harness, so as to prevent the operator from inserting his hand into the cover 4 through the gap between the port 41 and the wire harness, thereby further increasing the safety of the connector.

[0090] It should be noted that when the first protective sheet 413 or the second protective sheet 414 is removed from the cover 4, pressure is applied to the first protective sheet 413 or the second protective sheet 414 in the direction of the inside or outside of the cover 4 to deform the first protective sheet 413 or the second protective sheet 414, thereby causing the rib to break, so as to separate the first protective sheet 413 or the second protective sheet 414 from the cover 4.

[0091] Furthermore, refer to Figure 6 , Figure 8 and Figure 9 The second end face 13 is provided with positioning ribs 132. There are four positioning ribs 132, which are located at the four corners of the base body 1. The positioning ribs 132 are provided one-to-one with the metal ring sleeve 14. Each positioning rib 132 is located inside the metal ring sleeve 14, so as to increase the creepage distance between the second connecting section 22 and the metal ring sleeve 14 to a certain extent, thereby further increasing the safety of the connector. The corners of the cover body 4 are recessed inward to form a recessed area 43 corresponding to the positioning ribs 132. After the cover body 4 is installed on the base body 1, the positioning ribs 132 abut against the inner wall of the recessed area 43, so as to realize the positioning of the cover body 4 by the cooperation of the positioning ribs 132 and the inner wall of the recessed area 43, thereby increasing the connection stability between the cover body 4 and the base body 1.

[0092] Furthermore, refer to Figure 8 The end face of the cover 4 facing away from the base 1 has an identification area 44, so that the manufacturer can set warning messages, manufacturer information, connector model and other information in the identification area 44 by engraving, pasting or integral molding, so that users can distinguish the connectors.
