Description

Technical Field

[0001] This utility model relates to the structural technology of vehicle power socket components, and in particular to a composite positive electrode insert and a vehicle power socket using the positive electrode insert. Background Technology

[0002] Vehicle power sockets are important power supply connection devices inside vehicles, mainly used to charge electronic devices or power vehicle electrical appliances. Especially for new energy vehicles, due to their external discharge function, the number of vehicle power sockets used has increased significantly, used to connect external electrical devices to the vehicle.

[0003] For example, the Chinese utility model patent with application number CN202420488334.7, filed by the applicant on March 14, 2024, specifically discloses a flip-type vehicle power socket, including: a socket body, a flip cover and a steering pin. The flip cover is rotatably installed at the slot opening of the socket body. The steering pin is disposed through the pivot hole on the flip cover and the pivot hole of the socket body. The flip cover rotates around the steering pin to seal the slot opening of the socket body. A square locking block is provided inside both the pivot hole and the pivot hole.

[0004] For example, the Chinese invention patent application number CN202310097372.X filed by the applicant on January 20, 2023, specifically discloses an intelligent assembly line and process for automotive power sockets. This process involves setting up an assembly fixture to work with a negative electrode insert feeding assembly, a gasket feeding assembly, and a positive electrode insert assembly. Using pre-installed rivets as the assembly base, the negative electrode insert, insulating gasket, and elastic gasket are sequentially inserted through the rivets from bottom to top. This ensures that the negative electrode insert, insulating gasket, and elastic gasket will not be misaligned during transfer. Furthermore, the positive electrode insert assembly ensures that the positive electrode insert is initially positioned above the elastic gasket during installation. Then, guided by the engagement of the rivet head and the rivet, the positive electrode insert is directly inserted into the rivet. The connection is then completed through riveting, and subsequently, the mounting ring and the cover are automatically installed sequentially.

[0005] The aforementioned patent documents all disclose the specific structure of conventional vehicle power sockets. In the existing vehicle power sockets, positive electrode plugs and rivets are required during assembly. The positive electrode plug and other components are stacked and then riveted together by rivets. Since the positive electrode plug is located directly on top of the stacked components during stacking, the rivets need to penetrate through several stacked components from top to bottom, which requires high processing precision. This directly leads to an increase in processing difficulty. Therefore, there is an urgent need to develop a technical solution that can reduce processing precision and difficulty. Utility Model Content

[0006] To address the above problems, this utility model provides a composite positive electrode insert and a vehicle power socket using the positive electrode insert. Through pre-processing, a component consisting of a pre-connected positive electrode insert and a rivet is formed, allowing the positive electrode insert to be directly inserted through the integrated rivet during assembly of the vehicle power socket. This reduces the precision requirements for power socket assembly and makes assembly simpler and faster.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A composite positive electrode insert, comprising: Positive electrode insert and rivets; The positive electrode insert is provided to cover the rivet head at the end of the rivet.

[0008] As an improvement, the positive electrode insert includes an integrally connected covering portion and a contact portion; The covering portion surrounds and covers the outside of the nail head; The connecting piece extends outward from the covering portion, and the extending direction of the connecting piece is located in the axial direction of the rivet.

[0009] As an improvement, when the covering part does not cover the nail head, the covering part is U-shaped and includes a flat section and a bent section. The flat section has a φ-shaped hole, and the bent section is located at both ends of the flat section. The bent section is perpendicular to the flat section, and the connecting piece extends outward from either of the bent sections. At this time, the connecting piece is parallel to the flat section.

[0010] As an improvement, the shank of the rivet passes through the hole, and the shank is arranged in the opposite direction to the tab portion.

[0011] As an improvement, the diameter φ1 of the nail head, the diameter φ2 of the nail shank, and the diameter φ3 of the hole satisfy the relationship: φ1>φ3>φ2.

[0012] As an improvement, a notch is provided at the bend connection position of the flat segment and the bend segment.

[0013] As an improvement, the connector portion is provided with mounting holes for connecting external connection wires.

[0014] As an improvement, the width of the connecting portion is smaller than the width of the covering portion.

[0015] In addition, this utility model also provides a vehicle power socket, including the composite positive electrode plug as described in the above claims. The rivet of the composite positive electrode plug passes through the elastic washer, the insulating sheet, the negative electrode plug, the ceramic base, the inner cylinder and the bimetallic strip in sequence. The pressing end of the rivet is formed by pressing and expanding the pressing head to fix the positive electrode plug to the elastic washer, the insulating sheet, the negative electrode plug, the ceramic base, the inner cylinder and the bimetallic strip.

[0016] The beneficial effects of this utility model are as follows: (1) This utility model forms a pre-connected positive electrode plug and rivet component through pre-processing, so that when the vehicle power socket is assembled, the positive electrode plug can be directly inserted through the rivet connected in one piece, which reduces the assembly precision requirements of the power socket and makes the assembly simpler and faster. (2) By using the positive electrode insert to cover the rivet head, this utility model can improve the connection strength between the positive electrode insert and the rivet, and improve the conductivity stability of the vehicle socket in subsequent use, while reducing the assembly precision and difficulty. (3) By designing the structure of the positive electrode insert, the positive electrode insert is U-shaped, so that the positive electrode insert can be bent quickly when it covers the rivet head, making the covering action of the covering part on the rivet head faster, and the connected part after covering can be directly in a vertical state without additional operation. (4) This utility model provides notches at the connection points of the bending sections and flat sections on both sides of the covering part. The notches improve the bending ease of the bending section and eliminate stress concentration generated by the positive electrode insert after bending, resulting in more reliable quality after molding.

[0017] In summary, this utility model has the advantages of simple and quick assembly, good stability, and high connection strength, and is especially suitable for the technical field of component structure of vehicle power sockets (power access interfaces). Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Example 1: like Figure 1 As shown, a composite positive electrode plug and a vehicle power socket using the positive electrode plug include: Positive electrode insert 1 and rivet 2; The positive electrode insert 1 is configured to wrap around the head 21 of the rivet 2.

[0024] Specifically, the positive electrode insert 1 includes an integrally connected covering part 11 and a receiving part 12; The covering portion 11 surrounds and covers the outside of the nail head 21; The connecting piece 12 extends outward from the covering part 11, and the extending direction of the connecting piece 12 is located in the axial direction of the rivet 2.

[0025] It should be noted that, for example, the appendix to the specification of Chinese utility model patent with patent application number CN202420488334.7 Figure 1 As depicted, the positive electrode insert and rivet are separate components. During assembly, the positive electrode insert is prone to misalignment, which greatly increases the difficulty and precision of assembly.

[0026] Therefore, based on the existing positive electrode insert and rivet, the applicant has encapsulated the positive electrode insert 1 and rivet 2, so that the positive electrode insert 1 and rivet 2 are pre-processed to form an integrated positive electrode insert component. As a result, when assembling the vehicle power socket (power interface), the presence of rivet 2 makes it less likely for the positive electrode insert to wobble or misalign when assembled and not yet fixed by riveting. Thus, during riveting, the assembly accuracy of the positive electrode insert on the vehicle power socket (power interface) can be guaranteed, while also reducing the difficulty of assembly.

[0027] Furthermore, the positive electrode insert structure that uses the covering part 11 to cover and connect the nail head 21 has a more stable connection than the existing positive electrode insert structure where the rivet is directly inserted from top to bottom and then pressed and fixed. Moreover, the covering structure provides a higher connection strength between the positive electrode insert and the rivet.

[0028] Example 2: Referring to Example 1, the difference between Example 2 and Example 1 lies in the following: like Figures 2-4 As shown, when the covering part 11 does not cover the nail head 21, the covering part 11 is U-shaped and includes a flat segment 111 and a bent segment 112. The flat segment 111 has a φ-shaped hole 113. The bent segment 112 is located at both ends of the flat segment 111 and is perpendicular to the flat segment 111. The connecting piece 12 extends outward from either of the bent segments 112 and is parallel to the flat segment 111.

[0029] Furthermore, the shank 22 of the rivet 2 passes through the hole 113, and the shank 22 is arranged in the opposite direction to the connecting piece 12. The diameters φ1 of the rivet head 21, φ2 of the shank 22, and φ3 of the hole 113 satisfy the following relationship: φ1 > φ3 > φ2.

[0030] It should be noted that, preferably, the covering part 11 is U-shaped. When forming the positive electrode insert, the flat segment 111 of the positive electrode insert 1 is provided with a hole 113 for inserting the rivet 2. After the rivet 2 is inserted into the hole 113, the rivet head 21 is placed on the flat segment 111, within the U-shaped area, while the rivet rod 22 is outside the U-shaped area. Then, the bending segment 112 of the covering part 11 is folded directly from both sides to the middle, so that the positive electrode insert 1 and the rivet 2 can be covered and connected. The whole covering and connection process is convenient and simple.

[0031] Furthermore, it should be emphasized that when designing the covering part 11, the diameter of the contact part 12 used to connect the external positive terminal is set to extend horizontally outward from any of the bending sections 112. This allows the contact part 12 to be set in a vertical state directly after the bending section 112 is completed, without the need for additional processing, making the structure very reasonable.

[0032] To facilitate bending, notches 114 are provided at the bending connection points of the flat segment 111 and the bending segment 112. The notches 114 reduce the stiffness and strength at the bending connection points of the flat segment 111 and the bending segment 112, making the bending segment 112 easier to bend. Furthermore, stress can be released through the notches 114 during the bending process, ensuring the bending quality and effect.

[0033] To facilitate the installation of connecting wires, the connector portion 12 is provided with a mounting hole 121 for connecting external connecting wires. The mounting hole 121 allows the external connecting wires to be better connected to the connector portion 12.

[0034] In addition, to ensure the safety of the negative electrode, the width of the contact portion 12 is smaller than the width of the covering portion 11. Specifically, the smaller the width of the contact portion 12, the lower the possibility of a short circuit between the positive electrode plug 1 and the negative electrode plug, thus ensuring the safety of the vehicle power socket.

[0035] Example 3: The vehicle power socket of Embodiment 3 of this utility model is described with reference to Embodiments 1-2.

[0036] like Figure 5 As shown, a vehicle power socket includes a composite positive electrode plug as described in any one of embodiments 1-2. The rivet 2 of the composite positive electrode plug passes through an elastic washer, an insulating sheet, a negative electrode plug, a ceramic base, an inner cylinder, and a bimetallic strip in sequence. The pressing end of the rivet 2 is formed by a pressing expansion head to fix the positive electrode plug 1 to the elastic washer, the insulating sheet, the negative electrode plug, the ceramic base, the inner cylinder, and the bimetallic strip.

[0037] It should be noted that, compared with existing vehicle power sockets, the installation and connection strength of the positive plug of this utility model is greatly improved, avoiding the problem that the positive plug is easy to fall off the rivet. In addition, the crimping end of the rivet is located inside the inner cylinder, so that when the external plug is inserted into the socket during use, it will not be interfered with by the protrusion of the rivet head. Furthermore, when the crimping end of the rivet is crimped, the covering part of the positive plug 1 can withstand the pressure of the crimping equipment, making the expansion of the crimping end of the rivet more smooth.

[0038] 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.
