Description

Technical Field

[0001] The utility model belongs to the technical field of new energy vehicle charging, and specifically relates to a new type of new energy conversion plug. Background Art

[0002] With the rapid development of new energy vehicles, the number of new energy vehicles in use is also gradually increasing. Among the charging connectors of new energy vehicles, the charging gun is one of the essential tools for new energy vehicles to obtain energy. The charging gun in the existing technology includes a connected gun body and a D-shaped gun head. The gun head is connected to the power supply through a cable via a control module in the gun body. Although it can meet the general usage requirements, since the new energy charging adapter is a split structure, not only the connection between the gun head and the gun body must be strong enough, but also the sealing performance requirements are high. It is necessary to strictly prevent the inner cavity from contacting the outside air or water vapor. The conventional split adapter has limited connection sealing, especially when used for a long time, it is difficult to ensure the connection sealing, so its applicability and practicality are limited. Summary of the Invention

[0003] The purpose of the utility model is to provide a new type of new energy conversion plug which has a reasonable structure and is conducive to improving the sealing and waterproof performance.

[0004] The technical solution for achieving the purpose of the utility model is a new type of new energy conversion plug, comprising a first D-shaped gun head and a second D-shaped gun head formed by injection molding, a connection conversion joint sleeve is provided between the first D-shaped gun head and the second D-shaped gun head, a plurality of connection terminals are connected between the first D-shaped gun head and the second D-shaped gun head, and the connection conversion joint sleeve is integrally injection molded between the ends of the first D-shaped gun head and the second D-shaped gun head;

[0005] The connecting terminal is located in the connecting conversion joint sleeve.

[0006] Further preferably, the ends of the first D-shaped gun head and the second D-shaped gun head are integrally formed with an inserting boss, and the outer wall of the inserting boss is integrally formed with a plurality of convex strips;

[0007] The two ends of the connection conversion joint sleeve are injection-molded on the outer surface of the insertion boss.

[0008] More preferably, the cross-section of the connection conversion joint sleeve is D-shaped.

[0009] The present invention has positive effects: the structure of the present invention is reasonably arranged, the first D-shaped gun head and the second D-shaped gun head are injection-molded, and the connecting conversion joint sleeve is integrally injection-molded between the ends of the first D-shaped gun head and the second D-shaped gun head. Since the three structures are injection-molded, it can not only ensure the stability and reliability of the connection, but also help to improve the sealing and waterproof performance, while also ensuring the strength of the connection, and does not require additional assembly operations, and has strong applicability and good practicality.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0015] See Figures 1 to 2As shown, a new type of new energy conversion plug includes a first D-shaped gun head 1 and a second D-shaped gun head 2 that are injection molded, a connection conversion joint sleeve 3 is provided between the first D-shaped gun head and the second D-shaped gun head, a plurality of connection terminals 4 are connected between the first D-shaped gun head and the second D-shaped gun head, and the connection conversion joint sleeve is integrally injection molded between the ends of the first D-shaped gun head and the second D-shaped gun head; the connection terminals are located in the connection conversion joint sleeve. In this embodiment, the cross-section of the connection conversion joint sleeve is D-shaped. The first D-shaped gun head 1 and the second D-shaped gun head 2 are both injection molded, so as to ensure the overall strength and overall sealing and waterproof properties of the two structures. At the same time, the connection conversion joint sleeve is integrally injection molded between the above two structures, so that the overall structure is an integrally molded structure, which can ensure the sealing and waterproof properties of the connection, and is also conducive to ensuring the strength and stability of use, and does not require additional assembly operations, and is highly practical.

[0016] In actual use, the ends of the first and second D-shaped gun tips are integrally formed with insertion bosses 5, and the outer walls of these insertion bosses are integrally formed with a plurality of ridges 6. The ends of the connector adapter sleeve are injection molded onto the outer surfaces of the insertion bosses. The combination of the insertion bosses and the ridges increases the connection area and effectiveness during injection molding of the connector adapter sleeve, preventing loosening or falling off, while also ensuring joint strength and enhancing practicality.

[0017] The present invention has positive effects: the structure of the present invention is reasonably arranged, the first D-shaped gun head and the second D-shaped gun head are injection-molded, and the connecting conversion joint sleeve is integrally injection-molded between the ends of the first D-shaped gun head and the second D-shaped gun head. Since the three structures are injection-molded, it can not only ensure the stability and reliability of the connection, but also help to improve the sealing and waterproof performance, while also ensuring the strength of the connection, and does not require additional assembly operations, and has strong applicability and good practicality.

[0018] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.
