[0002] With the rapid development of the new energy vehicle industry, all new energy vehicle OEMs have stepped up their efforts to develop new models and vehicle high-voltage interconnection systems in order to seize the market; the vehicle high-voltage interconnection system is a platform system formed by high-voltage electrical devices connected by high-voltage wire harnesses, which include electrical connectors and cables. Due to the different models of different OEMs, the positions and arrangements of the internal high-voltage electrical appliances are different. The high-voltage connectors connected between high-voltage electrical appliances sometimes need to meet the requirements of different spatial directions in order to achieve flexible wiring of high-voltage wire harnesses.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below.

[0035] In the following description, the terms "first\second\third" and the like are only used to distinguish similar objects and do not represent a specific order for the objects. It is understandable that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present application. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application. The utility model is further described in detail below in conjunction with the examples, but the embodiments of the utility model are not limited thereto.

[0036] Embodiment 1:

[0037] Combined with Figure 1 -Attached Fig.14 As shown, an electrical connector socket with 90-degree outlet includes: an L-shaped socket shell 3, a front shielding cover 1, a rear shielding cover 11, a terminal front mounting plate 2, a terminal rear mounting plate 4, a power pin 5, a signal pin 7, a power jack 9, a signal jack 8, a terminal TPA6, a socket sealing ring 10 and a mounting screw sleeve 12; wherein, a transverse front shielding cover accommodating cavity 31 and a longitudinal rear shielding cover accommodating cavity 33 are provided in the L-shaped socket shell 3, and a socket sealing ring 10 and a mounting screw sleeve 12 are installed on the shell;

[0038] The front shielding cover 1 is axially mounted in the front shielding cover accommodating cavity 31, the front shielding cover 1 is provided with a terminal front mounting plate accommodating cavity 1a, and the terminal front mounting plate 2 is axially mounted in the terminal front mounting plate accommodating cavity 1a; the terminal front mounting plate 2 is provided with a power pin accommodating cavity and a signal pin accommodating cavity, one end of the power pin 5 is inserted into the power pin accommodating cavity, and the other end is inserted into the power socket 9, and one end of the signal pin 7 is inserted into the signal pin accommodating cavity, and the other end is inserted into the signal socket 8; the outer side of the terminal front mounting plate 2 is provided with a TPA assembly slide groove 26, and the terminal TPA6 is axially installed in the TPA assembly slide groove 26;

[0039] The rear shielding cover 11 is axially installed in the rear shielding cover accommodating cavity 33, the rear shielding cover 11 is provided with the terminal rear mounting plate accommodating cavity 111, and the terminal rear mounting plate 4 is axially installed in the terminal rear mounting plate accommodating cavity 111; the terminal rear mounting plate 4 is provided with a signal jack accommodating cavity 42 and a power jack accommodating cavity 41, the signal jack 8 is installed in the signal jack accommodating cavity 42, and the power jack 9 is installed in the power jack accommodating cavity 41.

[0040] Specifically, combined with Figure 1 , Attachment Figure 2 and attached Figure 8 As shown, the basic structure of the entire socket is an L-shaped socket shell 3, which is a solid protective layer that provides support and protection for the internal components. Its characteristic is that the connection direction of the pins and sockets is 90 degrees, so as to facilitate electrical connection in a specific space. Inside the shell, a plurality of accommodating cavities are specially designed for properly accommodating other components. These accommodating cavities include accommodating cavities for installing the front shielding cover 1 and the rear shielding cover 11, as well as special cavities prepared for the socket sealing ring 10 and the mounting screw sleeve 12. The front shielding cover 1 is an important electromagnetic shielding component, which is axially installed in the front shielding cover accommodating cavity 31 for shielding electromagnetic interference.

[0041] Combined with Figure 6 and attached Figure 7As shown, a terminal front mounting plate accommodating cavity 1a is provided inside the front shielding cover for installing the terminal front mounting plate 2. The terminal front mounting plate 2 is a key part of the electrical connection. It is provided with a specific accommodating cavity inside, which is used to fix the power pin 5 and the signal pin 7 respectively. In the present application, there are two power pins 5 and two signal pins 7 respectively. One end of these pins is inserted into the corresponding accommodating cavity, and the other end is connected to the corresponding socket, so as to ensure the smooth transmission of the electrical signal; at the same time, the terminal TPA6 is a safety device for ensuring that the pin or socket is correctly installed and locked in the predetermined position. It is usually a movable plastic or metal sheet, and when the pin or socket is correctly installed, it will be pushed into the TPA assembly slide 26 provided on the outside of the terminal front mounting plate 2. For example, in some automotive connectors, TPA can ensure that the connector will not loosen or fall off under vibration or impact.

[0042] Combined with Figure 8 , Attachment Fig. 9 and attached Fig.13 As shown, similar to the front shielding cover 1, the rear shielding cover 11 is also axially installed in the rear shielding cover accommodating cavity 33. A terminal rear mounting plate accommodating cavity 111 is also provided inside the rear shielding cover 11 for installing the terminal rear mounting plate 4. A signal jack accommodating cavity 42 and a power jack accommodating cavity 41 are provided inside the terminal rear mounting plate 4 for installing and fixing the signal jack 8 and the power jack 9. These jacks match the front pins to form a complete electrical connection path. The jacks are usually provided with spring sheets or contact sheets to ensure good contact with the pins. In addition, in combination with the attached Figure 1 As shown, a socket sealing ring 10 and a mounting screw sleeve 12 are mounted on the housing.

[0043] In addition, the socket is also equipped with a 90-degree outlet electrical connector socket. In general, this 90-degree outlet electrical connector socket ensures efficient and stable transmission of electrical signals through its precise design and rigorous assembly process. The various components cooperate with each other to form a complete and reliable electrical connection system, which is widely used in various occasions that require stable electrical connections, such as new energy vehicles, industrial automation and other fields.

[0044] Embodiment 2:

[0045] Based on Example 1, Figure 3 and attached Figure 4As shown, the L-shaped socket shell 3 is also provided with a front shielding cover elastic tooth hanging platform 32 and a rear shielding cover elastic tooth hanging platform 34, the upper wall surface of the rear end of the front shielding cover 1 is provided with a first elastic hanging tooth 1c, and the upper wall surface of the rear shielding cover 11 is provided with a terminal rear mounting plate accommodating cavity 112; when the front shielding cover 1 is assembled in place, the first elastic hanging tooth 1c is engaged and fixed with the front shielding cover elastic tooth hanging platform 32; when the rear shielding cover 11 is assembled in place, the terminal rear mounting plate accommodating cavity 112 is engaged and fixed with the rear shielding cover elastic tooth hanging platform 34.

[0046] Specifically, combined with Figure 4 As shown, the front shield cover spring tooth hanging platform 32 is a structure inside the L-shaped socket shell 3, which is used to match the first elastic hanging tooth 1c on the front shield cover 1. When the front shield cover 1 is assembled into the shell and pushed to the predetermined position, the first elastic hanging tooth 1c will automatically engage with the spring tooth hanging platform to form a mechanical lock, thereby ensuring that the front shield cover 1 will not be easily moved or fall off due to external force. This design is similar to the common pin and slot structure in our daily life. After the pin (first elastic hanging tooth 1c) is inserted into the slot (front shield cover spring tooth hanging platform 32), the two are tightly combined to provide a stable connection.

[0047] Similarly, the design of the rear shielding cover spring tooth hanging platform 34 and the terminal rear mounting plate accommodating cavity 112 also follows the same principle. When the rear shielding cover 11 is correctly assembled in place, the terminal rear mounting plate accommodating cavity 112 will engage with the rear shielding cover spring tooth hanging platform 34 to ensure the stability and reliability of the rear shielding cover 11. We can compare this fixing method to the relationship between the puzzle pieces and the puzzle board in a jigsaw puzzle. Each puzzle piece (shielding cover) has a specific shape (hanging teeth), and only when the puzzle pieces are correctly placed in the corresponding positions of the puzzle board (L-shaped socket housing 3) can they be tightly combined together. This design not only ensures the accuracy of assembly, but also greatly enhances the stability of the overall structure.

[0048] In summary, the design of these elastic tooth hanging platforms and elastic hanging teeth ensures that the shielding cover is accurately and firmly assembled in the L-shaped socket housing 3, thereby improving the performance and reliability of the entire electrical connector socket.

[0049] Furthermore, an axial positioning boss 24 is provided at the top of the rear end of the terminal front mounting plate 2. When the front shielding cover 1 is installed in place, the axial positioning boss 24 is axially fitted with the L-shaped socket shell 3. A rear shielding cover installation anti-error groove 37 is also provided in the L-shaped socket shell 3. The lower wall surface of the rear shielding cover 11 is provided with an installation anti-error frill 114. When the rear shielding cover 11 is assembled in place, the upper surface of the installation anti-error frill 114 is fitted with the lower surface of the installation anti-error groove.

[0050] Specifically, combined with Figure 7As shown, an axial positioning boss 24 is designed on the top of the rear end of the terminal front mounting plate 2. The function of this boss is to form an axial fit with the L-shaped socket housing 3 when the front shielding cover 1 is installed in place, thereby ensuring the precise position of the front shielding cover 1 during the assembly process. This design is similar to the "positioning blocks" in our common jigsaw puzzle games, that is, those irregularly shaped puzzle pieces, and their design purpose is to ensure that the puzzle pieces can only be placed in specific positions. The axial positioning boss 24 here plays such a role, which ensures that the front shielding cover 1 can only be installed in a predetermined and correct position.

[0051] Combined with Figure 8 and attached Fig.13 As shown, a rear shield cover installation error prevention groove 37 is further provided in the L-shaped socket housing 3. This error prevention groove cooperates with the installation error prevention hem 114 on the lower wall of the rear shield cover 11. When the rear shield cover 11 is assembled in place, the upper surface of the error prevention hem will fit tightly with the lower surface of the error prevention groove. This design not only ensures the accurate positioning of the rear shield cover 11, but also effectively prevents functional disorders caused by assembly errors.

[0052] In general, these designs are to ensure the accuracy and correctness of the shield during installation, thereby improving the reliability and performance of the entire electrical connector socket. Through this mechanical positioning and error-proofing mechanism, the possibility of human assembly errors is greatly reduced, providing a strong guarantee for the stability and safety of electrical connections.

[0053] Embodiment 3:

[0054] Based on Example 1, Figure 4 -Attached Figure 7 As shown, the front shielding cover 1 is provided with a second elastic hanging tooth 1b on both sides of the middle part, the terminal front mounting plate 2 is provided with an elastic tooth hanging platform A23 on both sides of the middle part, the upper wall of the rear shielding cover 11 is also provided with a mounting plate fixing elastic hanging tooth 113, and the middle part of the terminal rear mounting plate 4 is provided with an elastic tooth hanging platform B43; when the terminal front mounting plate 2 is assembled in place, the second elastic hanging tooth 1b is engaged and fixed with the elastic tooth hanging platform A23; when the terminal rear mounting plate 4 is assembled in place, the mounting plate fixing elastic hanging tooth 113 is engaged and fixed with the elastic tooth hanging platform B43.

[0055] Specifically, combined with Figure 5 and attached Figure 7As shown, second elastic hanging teeth 1b are designed on both sides of the middle part of the front shielding cover 1. These hanging teeth have a certain elasticity and are used to connect with the elastic tooth hanging platform A23 on the terminal front mounting plate 2 to achieve a fixing effect. Elastic tooth hanging platforms A23 are provided on both sides of the middle part of the terminal front mounting plate 2. These hanging platforms are designed to cooperate with the second elastic hanging teeth 1b. When the terminal front mounting plate 2 is assembled in place, the second elastic hanging teeth 1b on the front shielding cover 1 will tightly mesh with the elastic tooth hanging platform A23 on the terminal front mounting plate 2 to form a mechanical fixation. This design ensures a stable connection between the front shielding cover 1 and the terminal front mounting plate 2, and can effectively prevent relative movement caused by vibration or external force.

[0056] Similarly, combined with Figure 4 As shown, the upper wall of the rear shielding cover 11 is also provided with mounting plate fixing elastic hanging teeth 113, which are also elastic. The middle part of the terminal rear mounting plate 4 is provided with an elastic tooth hanging platform B43, which is used to match the mounting plate fixing elastic hanging teeth 113 on the rear shielding cover 11. When the terminal rear mounting plate 4 is assembled in place, the mounting plate fixing elastic hanging teeth 113 on the rear shielding cover 11 will be engaged and fixed with the elastic tooth hanging platform B43 on the terminal rear mounting plate 4. This design not only ensures the accuracy of assembly, but also greatly enhances the overall stability of the structure.

[0057] Taken together, these design details ensure a precise fit and secure connection between the shield and mounting plate, improving the reliability and performance of the entire electrical connection system.

[0058] Furthermore, a front shielding cover limiting boss 25 is provided at the lower portion of the rear end of the terminal front mounting plate 2. When the terminal front mounting plate 2 is assembled in place, the front shielding cover limiting boss 25 is axially fitted with the front shielding cover 1. A rear shielding cover limiting boss 44 is provided at the bottom of the lower end of the terminal rear mounting plate 4. When the terminal rear mounting plate 4 is assembled in place, the rear shielding cover limiting boss 44 is fitted with the bottom surface of the installation anti-mistake frill 114 in the rear shielding cover 11.

[0059] Specifically, combined with Figure 7 , Attachment Fig. 9 and attached Fig.13As shown, at the lower rear end of the terminal front mounting plate 2, a front shielding cover limiting boss 25 is designed, which is used to limit the position of the front shielding cover 1. When the terminal front mounting plate 2 is assembled to the correct position, the front shielding cover limiting boss 25 will axially fit with the front shielding cover 1. This design ensures the stability and position accuracy of the front shielding cover 1 during the assembly process. This boss is like a locating pin, ensuring that the front mounting plate and the front shielding cover 1 can be accurately assembled in the predetermined position. Similarly, a rear shielding cover limiting boss 44 is also provided at the bottom of the lower end of the terminal rear mounting plate 4. When the terminal rear mounting plate 4 is assembled in place, this boss will fit with the bottom surface of the installation error-proofing frill 114 inside the rear shielding cover 11. This design not only provides accurate positioning of the rear shielding cover 11, but also improves the stability of the assembly by increasing the contact area.

[0060] In summary, these designs ensure the precise assembly between the shielding cover and the mounting plate, which not only improves the overall quality and reliability of the product, but also effectively prevents functional failures caused by improper assembly. Through the precise matching of these limit bosses and the fitting surface, the stability and safety of the entire electrical connection system are significantly improved.

[0061] Embodiment 4:

[0062] Based on Example 1, Fig.10 -Attached Fig.12 As shown, the signal pin 7 and the power pin 5 are L-shaped, and the L-shaped transition of the power pin 5 and the signal pin 7 is provided with a TPA assembly positioning surface, and the terminal TPA6 is provided with an assembly guide platform 61, and a U-shaped insulating barrier rib 62 is provided on the assembly guide wall, and a terminal positioning surface 621 is provided on the inner side of the U-shaped insulating barrier rib 62; when the terminal TPA6 is assembled in place, the assembly guide platform 61 is engaged with the TPA assembly slide groove 26, and the terminal positioning surface 621 is flush with the TPA assembly positioning surface of the power pin 5 and the signal pin 7

[0063] Specifically, combined with Fig.12As shown, the signal pin 7 is a pin for transmitting signal current, which is usually responsible for transmitting weak current signals or data in the connector, just like the metal contacts in the headphone jack, which are used to transmit audio signals. The power pin 5 is a pin for transmitting a larger current, which is usually used to provide power or drive a larger load, similar to the metal sheet on the power adapter plug, which is used to provide power. Both the signal pin 7 and the power pin 5 are designed in an L-shape, which is usually designed to adapt to a specific spatial layout or to achieve specific electrical connection requirements. At the L-shaped transition, both pins are equipped with a TPA (Terminal Position Assurance) assembly positioning surface. This positioning surface ensures the accuracy and stability of the pin during the assembly process. The terminal TPA6 is designed with an assembly guide platform 61, which is used to provide guidance during assembly to ensure that the terminal can be accurately assembled to the predetermined position. On the assembly guide wall, a U-shaped insulating barrier rib 62 is designed, which not only enhances the stability of the structure, but also provides the necessary electrical insulation to ensure safe isolation between different circuits. A terminal positioning surface 621 is provided on the inner side of the U-shaped insulating barrier rib 62. Fig.10 and attached Fig.11 As shown, the terminal positioning surface 621 cooperates with the power pin TPA assembly positioning surface 51 and the signal pin TPA assembly positioning surface 71. When the terminal TPA6 is assembled in place, these positioning surfaces will be flush, ensuring the precise docking between the terminal and the pin. At the same time, the assembly guide platform 61 will be engaged in the specially designed TPA assembly slide 26. This engagement design further enhances the stability and reliability of the assembly.

[0064] In general, such design details ensure the precise assembly between the pins and the terminals, improving the stability and safety of the electrical connection.

[0065] Embodiment 5:

[0066] Based on Example 1, Figure 1 Attached Figure 8 and attached Fig.14 As shown, the L-shaped socket housing 3 is also provided with a socket sealing ring accommodating cavity 35 and a mounting screw sleeve accommodating cavity 36, the socket sealing ring 10 is accommodated in the socket sealing ring accommodating cavity 35, and the mounting screw sleeve 12 is accommodated in the mounting screw sleeve accommodating cavity 36; wherein, the mounting screw sleeve 12 is a hollow structure, the outer contour 121 is a knurled structure, and the socket sealing ring 10 is a rectangular upper and lower symmetrical double-lip structure.

[0067] Specifically, combined with Figure 1 and attached Figure 8As shown, the socket seal ring 10 and the mounting screw sleeve 12 are installed in the socket seal ring accommodating cavity 35 and the mounting screw sleeve accommodating cavity 36 respectively. The socket seal ring 10 is designed to be a rectangular upper and lower symmetrical double-lip structure. This structure means that the seal ring has raised lips in both the upper and lower directions, and these lips can fit more closely to the connection part, thereby providing a better sealing effect. The rectangular design ensures the stability and uniform pressure distribution of the seal ring, while the double-lip design enhances the sealing performance. We can imagine the socket seal ring 10 as a car tire valve, which usually has a double-layer rubber sealing ring. This is a double-lip structure used to ensure the sealing of the tire when it is inflated;

[0068] Combined with Fig.14 As shown, the mounting screw sleeve 12 is a threaded set for fixing or connecting parts, which is usually used to strengthen the stability of the connection or provide additional support. The mounting screw sleeve 12 is designed as a hollow structure to reduce weight, save materials, or provide space to accommodate other parts. The hollow structure can also provide heat insulation or sound insulation to a certain extent. In addition, the outer contour 121 of the screw sleeve adopts a knurling structure. Knurling is a texture formed on the metal surface, which can increase friction and make it easier to grip and rotate the screw sleeve during installation or removal. This design also improves the aesthetics and can prevent the screw sleeve from sliding during use to a certain extent. For example, we can compare the mounting screw sleeve 12 to a hollow tube with a pattern. The hollow design makes the tube lighter, and the pattern on the surface (knurling structure) allows us to grip it more easily when rotating the tube;

[0069] In summary, the design of the mounting screw sleeve 12 and the socket sealing ring 10 in this description is to improve the practicality and reliability of the product. The hollow and knurled screw sleeve design is both beautiful and practical, while the rectangular double-lip sealing ring ensures the tightness of the connection.
