Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and in particular relates to a 12-pin plug and socket. Background Technology

[0002] Connectors, as convenient connection components, have been widely used in various industries, such as the new energy vehicle industry. Due to different usage environments, there are various requirements for the cable exit direction of connectors. To improve versatility and reduce investment costs, sockets are usually shared, and plugs come in various cable exit angle forms, resulting in different structural forms such as straight and right-angle plugs. When connecting and fixing 12-pin right-angle plugs and sockets, a rotatable lever is often provided on the plug to facilitate the connection. By controlling the lever, a tight connection is ensured, preventing detachment.

[0003] The Chinese patent authorized by our company (Comparison 1), application number: 2024217250573, patent name: A 12-pin elbow plug and socket, the socket shell has multiple pin posts inside, the socket shell and multiple pin posts are integrally injection molded, each pin post has a slot for inserting pins, there is a gap between the multiple pin posts, and there is a reinforcing rib between every two pin posts, the reinforcing rib is not easy to deform during injection molding and demolding, and the plug assembly and socket assembly are not misaligned when they are inserted; when the plug assembly and socket assembly are inserted, the assist rod is in a vertical state. Pressing the front end of the assist rod causes the rotating groove of the assist rod to rotate around the locking post as the axis, the assist rod changes from a vertical state to a horizontal state. Then pressing the front end of the assist rod causes the locking hole at the front end to engage with the ball, completing the locking of the assist rod. At this time, the plug assembly and socket assembly are connected and fixed. The Chinese patent authorized by our company (Comparison 2), application number: 2024304529606, patent name: plug and socket, Comparison 2 and Comparison 1 were applied for on the same day. The appearance patent of Comparison 2 is a more intuitive illustration of the plug and socket of the embodiment in Comparison 1 from various perspectives.

[0004] The above patents also have the following shortcomings: Referring to the accompanying drawings of Comparison 1 or the bottom view of the design drawings or photographs in Comparison 2, the center distance between the two power pins (large cores) in the 12-pin plug is small. When the two power pins are too close, an electric arc can easily occur between the two wires, leading to accidents such as short circuits or fires. In the accompanying drawings of Comparison 1, the adjacent power pins, ground pins, data pins, and signal pins in the 12-pin plug are all provided with reinforcing ribs. However, the power pins, ground pins, data pins, and signal pins and the inner wall of the socket shell are not provided with reinforcing ribs. This can easily lead to injection molding deformation during the injection molding process, affecting the yield rate. The assist rod shown in the accompanying drawings of Comparison 1 is relatively heavy, which will consume more material during mass production. Therefore, this utility model proposes a 12-pin plug and socket to solve the above problems. Utility Model Content

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a 12-pin plug and socket, including a plug assembly 1 and a socket assembly 2; the plug assembly 1 includes a plug housing 11, an assist rod 12, and a plug 13, the plug 13 being inserted into one side port of the plug housing 11, the plug housing 11 being rotatably connected to the assist rod 12, the assist rod 12 being locked by a locking mechanism, the assist rod 12 having multiple grooves 121 provided on it, the multiple grooves 121 being spaced apart along the extension direction of the assist rod 12; the socket assembly 2 includes a socket housing 21, the outer wall of the socket housing 21 having a locking post 22, and the interior of the socket housing 21 having two oppositely distributed power pin posts 23, for power... The power pin 23 is close to the locking pin 22. A reinforcing rib 26 is provided between the power pin 23 and the inner wall of the socket housing 21. A grounding pin 24 is provided on one side of the two power pins 23. Data / signal pins 25 are provided on both sides of the grounding pin 24. Data / signal pins 25 are also provided on the other side of the two power pins 23. A baffle 27 is also provided inside the socket housing 21 to prevent high voltage breakdown. A reinforcing rib 26 is provided between the grounding pin 24, the baffle 27, and the inner wall of the socket housing 21. A reinforcing rib 26 is also provided between the data / signal pins 25, the baffle 27, and the inner wall of the socket housing 21.

[0023] In this embodiment, please refer to Figure 1 and Figure 4 The assist rod 12 is provided with multiple grooves 121, which are distributed at intervals along the extension direction of the assist rod 12. The grooves 121 can effectively reduce the weight of the assist rod 12 and also reduce material consumption during injection molding, thus saving costs. Please see Figure 2 and Figure 3The socket housing 21 contains a rectangular space. A locking post 22 is located on the outer wall of the shorter side of this rectangular space. Two opposing power pin posts 23 are located on the inner side of the shorter side of this rectangular space, close to the locking post 22. Considering the characteristics of the power pins and optimal layout within the limited space, the distance between the two power pin posts 23 is maximized. Increasing the center-to-center distance of the two power pin posts 23 effectively prevents arcing between the two wires when they are too close, which could lead to short circuits or fires. A grounding pin is also included. The socket housing 21 is integrally injection molded with the power pins 23, ground pins 24, and data / signal pins 25, including pin 24 and pin 25. Each power pin 23, ground pin 24, and data / signal pin 25 has a slot for inserting pins. There are gaps between adjacent power pins 23, ground pins 24, and data / signal pins 25, and reinforcing ribs 26 are provided between these gaps. The socket housing 21 also has a baffle 27 inside, which separates two power pins 23 into a single space (see appendix for details). Figure 3 The baffle 27 is used to prevent high voltage breakdown and short circuit caused by contact between two wires. The grounding pin 24 is provided with reinforcing ribs 26 between the baffle 27 and the inner wall of the socket housing 21. The data / signal pin 25 is also provided with reinforcing ribs 26 between the baffle 27 and the inner wall of the socket housing 21. The reinforcing ribs 26 make the power pin 23, grounding pin 24 and data / signal pin 25 less prone to deformation during injection molding and demolding, and prevent the plug assembly 1 and socket assembly 2 from being misaligned when they are plugged in. Compared with Comparative Example 1 (Application No.: 2024217250573, Patent Name: A 12-pin Elbow Plug and Socket), the groove 121 in this embodiment can effectively reduce the weight of the assist rod 12 and also reduce material consumption during injection molding, saving costs. There is a rectangular space inside the socket housing 21. Considering the characteristics of the power pins and reasonable layout within the limited space, the distance between the two power pin posts 23 is maximized. Increasing the center distance between the two power pin posts 23 can effectively avoid the arcing between the two wires when the two power pins are too close, which can easily lead to short circuits or fires. Reinforcing ribs 26 are added between the power pin posts 23, grounding pin posts 24 and data / signal pin posts 25 and the inner wall of the socket housing 21 to prevent injection molding deformation and ensure the concentricity of the two power pin posts 23. The baffle 27 is used to prevent high voltage breakdown and prevent the two wires from contacting each other and causing a short circuit.

[0024] For further details, please refer to Figure 1 A limiting plate 14 is provided on the outer side of the plug housing 11.

[0025] For further details, please refer to Figure 1 The top surface of the limiting plate 14 is provided with a protrusion 1, and the inner wall of the limiting groove 124 is provided with a protrusion 2. When the protrusion 1 and the protrusion 2 come into contact, the rotation of the assist rod 12 is restricted.

[0026] For further details, please refer to Figure 5 The assist rod 12 is provided with a limiting groove 124, which cooperates with the limiting plate 14 to limit the assist rod 12. The assist rod 12 is also provided with a rotating groove 125.

[0027] In this embodiment, when the plug assembly 1 and the socket assembly 2 need to be inserted, the assist rod 12 is in a vertical state. At this time, protrusion one and protrusion two are in contact, restricting the rotation of the assist rod 12, which facilitates the insertion of the plug assembly 1 and the socket assembly 2. When the plug assembly 1 and the socket assembly 2 are inserted, the assist rod 12 is in a vertical state. Pressing the front end of the assist rod 12 causes the rotating groove 125 of the assist rod 12 to rotate around the locking post 22 as an axis, and the assist rod 12 changes from a vertical state to a horizontal state. Then, pressing the front end of the assist rod 12 causes the locking hole 126 at the front end to engage with the ball post 18, completing the locking of the assist rod 12. At this time, the plug assembly 1 and the socket assembly 2 are connected and fixed.

[0028] For further details, please refer to Figure 4 The locking mechanism includes a limiting post 15, a fixing plate 16, a spring 17, and a ball post 18. The limiting post 15 is located at the connection end between the plug housing 11 and the plug 13. The fixing plate 16 is located at the connection end between the plug 13 and the plug housing 11. A sliding groove is provided inside the limiting post 15. The spring 17 is located inside the sliding groove. One end of the spring 17 is connected to the fixing plate 16, and the other end is connected to the end face of the ball post 18.

[0029] For further details, please refer to Figure 4 The front end of the assist rod 12 has a snap-fit ​​hole 126, which snaps into the ball end of the ball post 18.

[0030] In this embodiment, when the assist rod 12 needs to be locked, pressing the assist rod 12 changes it from a vertical state to a horizontal state. At this time, the ball post 18 is squeezed by the front end of the assist rod 12, and the spring 17 carries the ball post 18 into the sliding groove inside the limiting post 15. When the assist rod 12 is in a horizontal state, the ball post 18 is directly facing the locking hole 126 at the front end of the assist rod 12. Under the action of the restoring force, the spring 17 pushes the ball post 18 into the locking hole 126, completing the locking of the assist rod 12. The size of the sliding groove inside the limiting post 15 is slightly larger than the maximum outer diameter of the spring 17 and the ball post 18.

[0031] For further details, please refer to Figure 5 The assist rod 12 is provided with two relatively spaced connecting plates 122, and a rotating pin 123 is provided on the opposite surface of the two connecting plates 122. The rotating pin 123 is rotatably connected to the plug housing 11.

[0032] In this embodiment, the rotating pin 123 is rotatably connected to the plug housing 11, and the assist rod 12 rotates on the plug housing 11 with the rotating pin 123 as the axis. When the plug assembly 1 and the socket assembly 2 need to be inserted, the assist rod 12 is in a vertical state. After the plug assembly 1 and the socket assembly 2 are inserted, the locking post 22 enters the rotating groove 125. Pressing the front end of the assist rod 12 causes the rotating groove 125 of the assist rod 12 to rotate with the locking post 22 as the axis, and the assist rod 12 changes from a vertical state to a horizontal state. Then, pressing the front end of the assist rod 12 causes the locking hole 126 at the front end to engage with the ball post 18, thus locking the assist rod 12. At this time, the plug assembly 1 and the socket assembly 2 are connected and fixed.

[0033] For further details, please refer to Figure 5 The rotating groove 125 has an arc-shaped structure. The inner wall of the rotating groove 125 is provided with an arc plate. The top surface of the locking column 22 is provided with a locking groove. The arc plate and the locking groove are rotated and locked together.

[0034] In this embodiment, the rotating groove 125 has an arc-shaped structure, and the inner wall of the rotating groove 125 is provided with an arc plate. The top surface of the locking column 22 is provided with a locking groove. The arc plate and the locking groove are rotated and locked together, so that the limiting position of the assist rod 12 is more accurate and the movement is more stable when it rotates.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
