[0002] This application claims priority to Chinese Patent Application No. 202411660984.6, filed on November 19, 2024, entitled "Socket Housing, High Voltage Connector, Electric Drive Assembly and Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of connector technology, specifically relating to a socket housing, a high-voltage connector, an electric drive assembly, and a vehicle. Background Technology

[0004] Connectors are intermediate structures that enable electrical connections and signal transmission between electrical components. They are widely used in various electrical devices, such as in new energy vehicles, where electrical connections between multiple electrical components are achieved through connectors. Currently, the socket end of a connector is typically fixed to the electric drive housing using a flange and bolts. The socket end is fitted with a sealing ring and a metal shielding element for sealing and shielding. The sealing ring is usually located on the contact surface between the flange and the housing for end-face sealing, and the metal shielding element contacts the housing to achieve 360° radial or end-face shielding. This design has some redundancy, leading to increased material costs and a larger connector size, which affects the utilization of interior space. Summary of the Invention

[0005] The purpose of this application is to provide a socket housing, a high-voltage connector, an electric drive assembly, and a vehicle, which simplifies the connector structure, reduces material costs, and achieves miniaturization of the structure while ensuring the normal operation of the connector, thereby improving the utilization rate of the vehicle interior space.

[0006] To achieve the above objectives, this application provides a socket housing; the socket housing has a through-hole forming a mating space, a first end of which is used for insertion and mating with a terminal block, and a second end of which is used for insertion and mating with a female connector end. A shielding ring surface and a sealing ring surface are formed on the peripheral wall of the mating space for being spaced apart from the terminal block. The shielding ring surface is used to abut against the shielding element of the female connector end, and the sealing ring surface is used to abut against the sealing ring of the female connector end.

[0007] In some embodiments, the inner diameter of the shielding ring is smaller than the inner diameter of the sealing ring, so as to form a first stepped surface between the shielding ring and the sealing ring, which is disposed at the second end facing the mating space. The first stepped surface is used to make endo-abutment with the sealing ring of the connector female end.

[0008] In some embodiments, the socket housing includes a mounting base plate having a mounting through hole and a mounting enclosure plate disposed on the mounting base plate surrounding the mounting through hole. The enclosing space of the mounting through hole and the mounting enclosure plate is combined to form a mating space. The peripheral wall of the mounting through hole is configured as a shielding annular surface, the inner peripheral wall of the mounting enclosure plate is configured as a sealing annular surface, and the periphery of the mounting through hole is configured as a first stepped surface.

[0009] In some embodiments, the mounting plate includes a sealing portion and a blocking portion arranged sequentially from the mounting base plate outwards. The sealing portion forms a sealing annular surface, and the blocking portion has a notch for the connector female end to extend laterally into the mating space.

[0010] In some embodiments, the socket housing further includes a socket base plate for connecting terminals. The socket base plate has a connecting portion at the gap between the terminals, and a connecting cross plate corresponding to the connecting portion is provided in the mating space. The connecting portion and the connecting cross plate are detachably connected.

[0011] In some embodiments, the socket base plate can be endo-abutted with the first end of the socket housing, the wiring terminal is provided with an insulating sleeve, and the side of the insulating sleeve facing the inner wall of the docking space has a protruding elastic buckle portion that can be pressed against the inner wall of the docking space.

[0012] In some implementations, the shielding ring surface and the sealing ring surface are configured to have smooth surfaces.

[0013] To achieve the above objectives, a second aspect of this application provides a high-voltage connector, wherein the high-voltage connector includes a connector female end, a wiring terminal, and the aforementioned socket housing, and the front end of the connector female end is provided with a metal shield and a sealing ring in sequence.

[0014] To achieve the above objectives, a third aspect of this application provides an electric drive assembly, wherein the electric drive assembly includes the aforementioned high-voltage connector.

[0015] To achieve the above objectives, a fourth aspect of this application provides a vehicle, wherein the vehicle includes the aforementioned high-voltage connector or electric drive assembly.

[0016] Through the above technical solution, the socket housing forms a mating space for electrical connection between the terminal block and the connector female end. A shielding ring and a sealing ring are formed on the peripheral wall of the mating space. When the connector female end is inserted into the mating space from the second end, the outer shell of the connector female end is placed between the terminal block and the socket housing. The metal shield and sealing ring on the outer shell abut against the shielding ring and sealing ring respectively. Compared with existing connectors, the socket housing provided in this application directly abuts against the connector female end. By setting the shielding ring and sealing ring instead of the flange of the existing connector socket, and using the metal shield and sealing ring on the connector female end, signal shielding and sealing between the terminal block, socket housing, and connector female end are achieved. This eliminates the need for the flange and the corresponding sealing ring and metal shield, reducing the cost of the socket and enabling miniaturization of the socket, freeing up space for other structures or equipment in the vehicle and improving the utilization rate of the vehicle's interior space.

Specific Implementation

[0026] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0027] The socket housing 2, high-voltage connector, electric drive assembly, and vehicle of this application are described below with reference to the accompanying drawings.

[0028] As shown in Figures 1 and 2, this application provides a socket housing 2:

[0029] The socket housing 2 has a through-hole forming a mating space 21. The first end of the mating space 21 is for inserting the wiring terminal 12, and the second end is for inserting and mating with the connector female end.

[0030] The inner wall of the socket housing 2 is formed with a shielding ring surface 211 and a sealing ring surface 212 spaced apart from the terminal block 12. The shielding ring surface 211 is used to abut against the shield of the female connector end, and the sealing ring surface 212 is used to abut against the sealing ring of the female connector end.

[0031] Through the above technical solution, the socket housing 2 forms a mating space 21 for electrical connection between the terminal 12 and the connector female end. A shielding ring surface 211 and a sealing ring surface 212 are formed on the peripheral wall of the mating space 21. When the connector female end is inserted into the mating space 21 from the second end, the outer shell of the connector female end is placed between the terminal 12 and the socket housing 2. The metal shielding element and sealing ring on the outer shell abut against the shielding ring surface 211 and the sealing ring surface 212 respectively. Compared with existing connectors, the socket housing 2 provided in this application directly abuts against the connector female end. The shielding ring surface and sealing ring surface replace the flange of the existing connector socket for mating with the connector female end, thus eliminating the need for the flange and the corresponding sealing ring and metal shielding element. This reduces the cost of the connector socket and also achieves miniaturization of the socket, freeing up space for other structures or equipment in the vehicle and improving the utilization rate of the vehicle's interior space.

[0032] Furthermore, referring to Figures 4 and 6, the socket body 1 also integrates an interlocking harness terminal 15. After the socket body 1 and the connector female end are connected, the wiring terminal 12 and the interlocking harness terminal 15 respectively connect the high-voltage circuit and the low-voltage circuit of the electrical equipment to form a high-voltage interlocking circuit. In the high-voltage interlocking circuit, the low-voltage circuit can be used to detect the electrical integrity or continuity of high-voltage components, wires and connectors, identify abnormal circuit disconnection, and disconnect the controller at the high-voltage input end in a timely manner to prevent electric shock caused by improper human operation, vehicle vibration, product aging, and line wear.

[0033] Specifically, the female end of the connector is generally a plug, but it can also be an adapter or other plug-in component with a similar structure.

[0034] As shown in Figure 2, in some embodiments, the inner diameter of the shielding ring surface 211 is smaller than the inner diameter of the sealing ring surface 212, so as to form a first stepped surface 213 between the shielding ring surface 211 and the sealing ring surface 212, which faces the second end of the mating space 21. The first stepped surface 213 can abut against the sealing ring of the connector female end. The first stepped surface 213 can limit the connector female end, ensuring that the metal shield and sealing ring of the connector female end abut against the shielding ring surface 211 and the sealing ring surface 212. On the other hand, when inserted into place, the friction between the connector female end and the socket housing 2 and the socket body 1 can elastically press the sealing ring against the first stepped surface 213, thereby further improving the sealing effect between the connector female end, the socket housing 2 and the socket body 1.

[0035] Specifically, the first step surface 213 can be machined to be inclined towards the shielding ring surface 211 from the self-sealing ring surface 212, thereby forming a gradually narrowing transition section in the mating space 21. When the operator inserts the connector female end into the mating space 21, the operator cannot observe the relative position of the connector female end and the opening at the shielding ring surface 211 due to the obstruction of the socket housing 2. Therefore, the transition section can provide guidance for the connector female end. When the connector female end abuts against the first step surface 213, the operator continues to apply a pushing force to the connector female end. The metal shield on the connector female end will enter the area of ​​the shielding ring surface 211 along the first step surface 213, which facilitates the operator to insert the connector female end and avoids the problem of the metal shield collide and deform with the first step surface 213 due to excessive force applied by the operator.

[0036] As shown in Figures 2 to 4, in some embodiments, the socket housing 2 includes a mounting base plate 22 with a mounting through hole and a mounting surround plate 23 disposed on the mounting base plate 22 surrounding the mounting through hole. The enclosed space of the mounting through hole and the mounting surround plate 23 forms a mating space 21. The peripheral wall of the mounting through hole is set as a shielding annular surface 211, the inner peripheral wall of the mounting surround plate 23 is set as a sealing annular surface 212, and the periphery of the mounting through hole is set as a first stepped surface 213. The addition of the mounting base plate 22 provides a larger contact area between the socket housing and the electrical equipment, ensuring installation stability. Furthermore, the mounting base plate 22 facilitates the opening of connection holes for bolts to pass through. The mounting surround plate 23 provides enclosure protection for the socket body 1 and the terminals of the connector female end. It should be noted that the above embodiments are only one structure of the socket housing 2 provided in this application. The mounting base plate 22 can be adapted to most electrical equipment. If the interface of the electrical equipment is an embedded structure, the mounting base plate 22 can be omitted, and only the mounting surround plate 23 is provided and embedded within the interface.

[0037] Furthermore, referring to Figure 2, locking parts 234 are also provided on both sides of the mounting plate 23. A rotatable latch is provided on the female connector end. After the female connector end is connected to the socket body 1, the latch is rotated to lock the latch and the locking part 234, thereby improving the reliability of the connection between the female connector end and the socket body 1. Even if there is severe shaking or impact, the female connector end will not come out of the socket housing 2 due to the action of the latch and the locking part 234.

[0038] As shown in Figure 4, in some embodiments, the mounting plate 23 includes a sealing portion 231 and a blocking portion 232 arranged sequentially outward from the mounting base plate 22. The sealing portion 231 forms a sealing annular surface 212, and the blocking portion 232 has a notch for the connector female end to extend laterally into the mating space 21. Through the notch formed by the blocking portion 232, the socket housing 2 provided in this application can be adapted to both straight connector female ends and bent connector female ends. For bent connector female ends, the rear wiring can be led out from the notch.

[0039] Furthermore, referring to Figures 3 and 4, a second stepped surface 233 is formed between the blocking portion 232 and the sealing portion 231, facing the second end of the mating space 21, to stop the connector female end and prevent the sealing ring from being squeezed and deformed due to excessive force applied by the operator when inserting the connector female end. Correspondingly, the connector female end forms at least two stepped structures in sequence along the axial direction, respectively corresponding to the first stepped surface 213 and the second stepped surface 233.

[0040] Furthermore, the notch of the enclosure 232 is U-shaped, which can prevent the connector female end from scratching the two sides of the notch.

[0041] As shown in Figure 4, in some embodiments, the socket housing 2 further includes a socket base plate 11 for connecting the wiring terminals 12. The socket base plate 11 has a connecting portion 13 at the gap between the wiring terminals 12, and a connecting horizontal plate 24 corresponding to the connecting portion 13 is also provided in the mating space 21. The connecting portion 13 and the connecting horizontal plate 24 are detachably connected by fasteners 25, thereby realizing the integrated design of the connector socket. Specifically, the fastener 25 is a bolt, the connecting portion 13 has a corresponding threaded hole, and the connecting horizontal plate 24 has a through hole for the fastener 25 and the interlocking wire harness terminal 15 to pass through.

[0042] Specifically, the connecting plate 24 includes a connecting plate body and side plate portions at both ends of the connecting plate body. The side plate portion away from the connecting plate body extends toward the shielding ring surface 211 and is provided with a connecting section. The connecting section connects to the shielding ring surface 211 and makes a certain gap between the side plate portion and the shielding ring surface 211, so that the metal shielding component can extend into the space between the side plate portion and the shielding ring surface 211.

[0043] As shown in Figures 3 and 4, in some embodiments, there are two terminals 12, and the connecting part 13 is placed between the two terminals 12, thereby effectively utilizing the space of the socket substrate 11, making the structure of the socket body 1 more compact, and realizing the miniaturization of the connector socket.

[0044] Furthermore, the socket base plate 11 also integrates a busbar, which can replace the wire to connect the terminal block 12, thereby further improving the anti-interference capability of the connector socket and saving space.

[0045] As shown in Figures 4, 5, and 6, in some embodiments, the socket base plate 11 can abut against the side of the mounting base plate 22 facing away from the mounting enclosure 23. The socket base plate 11 is also provided with an insulating sleeve 14 that covers the wiring terminal 12. The insulating sleeve 14 has a protruding elastic latching part 141 on the side facing the inner wall of the mating space 21, which can be pressed tightly against the inner wall of the mating space 21. The elastic latching part 141 allows for quick assembly and disassembly of the socket housing 2 and the socket body 1, improving the efficiency of operators in assembling and maintaining the corresponding electrical equipment.

[0046] Specifically, the insulating sleeve 14 is made of one-piece plastic molding. Referring to Figure 6, the socket base plate 11 has a notch at the position corresponding to the elastic snap part 141, and the insulating sleeve 14 forms a hollow area between the elastic snap part 141 and the notch. The elastic snap part 141 includes an elastic plate part and a stop part. Cutouts are provided on both sides of the elastic plate part to allow the elastic plate part to be elastically pressed down. The stop part protrudes from the elastic plate part. Further, in order to achieve the snap-fit ​​fixation between the elastic snap part 141 and the socket housing 2, the distance between the elastic snap part 141 and the socket base plate 11 can be set to the thickness of the mounting base plate 22, and the elastic snap part 141 and the socket base plate 11 respectively abut against the two sides of the mounting base plate 22; or a groove corresponding to the elastic snap part 141 can be opened on the inner wall of the mating space 21.

[0047] Further, referring to Figures 4 and 6, the insulating sleeve 14 includes a first sleeve portion 142 and a second sleeve portion 143 sequentially arranged from the socket base plate 11. The first sleeve portion 142 is fully enclosed to protect the wiring terminal 12, and an elastic snap portion 141 is provided on the first sleeve portion 142. The second sleeve portion 143 is semi-open around the wiring terminal 12. An opening is formed at the second end of the second sleeve portion 143 facing the mating space 21 to allow the terminal of the connector female end to extend into the gap between the second sleeve portion 143 and the wiring terminal 12. An opening is also formed on the side of the second sleeve portion 143 facing the notch of the enclosure portion 232 to allow the bent connector female end to be mated.

[0048] Furthermore, the two closed corners of the second assembly 143 are designed with rounded corners on one side and right angles on the other side. The shape of the connector female end is designed to match the shape of the second assembly 143. By using different corner shapes, a foolproof function can be achieved, ensuring that the connector female end and the terminals of the socket body can only be connected in a one-to-one correspondence, avoiding the problem of circuit failure caused by reverse insertion.

[0049] It should be noted that in the above embodiments, the connection between the socket body 1 and the socket housing 2 can be either a bolt connection or a snap-fit ​​connection, or both bolt connections and snap-fit ​​connections can be used simultaneously. When both bolt connections and snap-fit ​​connections are used simultaneously, the elastic snap-fit ​​portions 141 of the two insulating sleeves 14 are arranged perpendicularly to the connecting cross plate 24, thereby improving the reliability of fixing the socket body 1.

[0050] In some embodiments, the mounting base plate 22 and mounting enclosure plate 23 of the socket housing 2 are integrally formed metal parts to guide interference signals. Preferably, the mounting base plate 22 and mounting enclosure plate 23 are made of aluminum.

[0051] In some embodiments, the shielding annular surface 211 and the sealing annular surface 212 are configured to have smooth surfaces. This smoothness is achieved through machining, ensuring that the metal shield and sealing ring on the connector female end can make full contact with the shielding annular surface 211 and the sealing annular surface 212. Specifically, the roughness Ra of the shielding annular surface 211 and the sealing annular surface 212 is set to 0.5-0.7 μm. Preferably, the roughness Ra of the shielding annular surface 211 and the sealing annular surface 212 is set to 0.6 μm. However, the invention is not limited to this; the shielding annular surface 211 and the sealing annular surface 212 may also be threaded to accommodate an external thread section on the connector female end.

[0052] To achieve the above objectives, a second aspect of this application provides a high-voltage connector. The high-voltage connector operates at a voltage above 60V and is primarily responsible for transmitting large currents. The high-voltage connector includes a connector female end, terminal blocks 12, and the aforementioned socket housing 2. A metal shield and a sealing ring are sequentially provided at the front end of the connector female end. By integrating the socket housing 2, signal shielding and sealing functions can be achieved solely through the metal shield and sealing ring of the connector female end, thus miniaturizing the high-voltage connector and reducing its cost.

[0053] Specifically, the metal shielding component is made of a metal material with good conductivity and includes a ring body and contacts extending from the ring body. The ring body is arranged around the insulating shell of the connector female end to achieve 360° shielding. There are multiple contacts, which are arranged sequentially and at intervals along the ring body. One end of each contact is connected to the ring body, and the other end is tilted outwards. When the connector female end mates with the socket housing 2, there is some interference between the contacts and the socket housing 2, causing the contacts to press downwards towards the center of the mating space 21. A certain pressure exists between the contacts and the socket housing 2, ensuring effective contact between the contacts and the shielding ring surface, thus guaranteeing the reliability of the shielding. Furthermore, there are 22 contacts, arranged sequentially and at intervals around the ring body. In other implementation methods of this application, the contacts can also be configured such that both ends are connected to the ring body, and the center of the contact protrudes upwards. The ring body has openings corresponding to the contact positions. This scheme can also achieve elastic contact between the contacts and the shielding ring surface.

[0054] Specifically, the sealing ring is preferably a three-lip sealing ring, with its three lips radially abutting against the sealing ring surface 212. Generally, considering the ease of insertion and removal between the connector female end and the socket housing 2, the connection between the connector female end and the socket housing 2 relies on friction, resulting in low axial pressure on the sealing ring. The three-lip sealing ring can more effectively ensure airtightness and waterproof performance. Of course, this application is not limited to this; if the connector female end and the socket housing 2 are connected by threaded tightening, the three-lip sealing ring can be replaced with a regular sealing ring. By screwing the connector female end to press the sealing ring onto the first step surface 213, a seal between the connector female end and the socket housing 2 can also be achieved.

[0055] A third aspect of this application provides an electric drive assembly, wherein the electric drive assembly includes the aforementioned high-voltage connector.

[0056] Specifically, the electric drive assembly includes an electric drive housing, and the socket housing 2 is configured as part of the electric drive housing. That is, the socket housing 2 can be integrated into the electric drive housing, integrating the plugging function into the electric drive housing, resulting in a high degree of integration and reducing the number of parts. This eliminates the need for a separate high-voltage connector, and also eliminates the need for flanges on the high-voltage connector to be bolted to the electric drive housing.

[0057] The fourth aspect of this application provides a vehicle, wherein the vehicle includes the above-mentioned high-voltage connector or electric drive assembly. Since the vehicle adopts all the technical solutions of the above embodiments, it has at least the above-mentioned beneficial effects, which will not be repeated here.
