[0002] With the rapid development of new energy vehicle technology, higher requirements have been placed on the reliability, durability, and electrical performance of automotive connectors. Traditional connectors rely on increasing frictional resistance or thread tightening, which may suppress loosening in the short term, but leads to a sharp increase in insertion and extraction forces, accelerates plating wear and plastic deformation, has poor stability, and is prone to loosening over time. In addition, the contact stability is poor under vibration. Furthermore, due to limitations in installation space and heat dissipation requirements, it is difficult to meet the dual requirements of relatively large current transmission and compact design.

The support module includes an elastic contact component and a substrate support platform, with the substrate support platform located inside the frame. The elastic contact component includes two sets of vertically mirror-arranged curved contact pieces and two sets of vertically mirror-arranged bent abutment pieces. The curved contact pieces and bent abutment pieces abut against the outer surface of the inserted port.

The following description is based on the accompanying drawings. Figure 1-4 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] 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 indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of this utility model, a connector adapted for new energy vehicles is provided for connecting ports. It includes a frame 100 with an opening on one side and a support module 200. The support module 200 includes an elastic contact component 210 and a substrate support platform 220, with the substrate support platform 220 located inside the frame 100. The elastic contact component 210 includes two sets of vertically mirror-arranged curved contact pieces 211 and two sets of vertically mirror-arranged bent abutment pieces 212. The curved contact pieces 211 and bent abutment pieces 212 abut against the outer surface of the inserted port. The common side of the curved contact pieces 211 and bent abutment pieces 212 faces the opening of the frame 100, and the common other side is connected to the substrate support platform 220. The substrate support platform 220 has a first pin 230 for connecting to the port in the direction facing the opening of the frame 100, and the first pin 230 is located between the two curved contact pieces 211. The substrate support stage 220 is also provided with a second pin 240 that penetrates the frame 100. The first pin 230 and the second pin 240 are arranged perpendicularly and are electrically connected to each other.

[0028] Specifically, in this design, the upper and lower double-layer elastic structure allows the connector to automatically adjust its shape during insertion and removal, tightly fitting ports of different sizes and preventing loosening or wear. Simultaneously, the spring contacts on both layers work together to distribute the pressure during insertion and removal. The internal metal pins adopt a vertically crossed layout, allowing the current transmission path to run vertically, adapting to specific communication methods and reducing energy loss and heat generation.

[0029] Furthermore, the curved contact piece 211 has a gradually curvature structure. A limiting protrusion 213 is provided at the end of the upper curved contact piece 211, followed by an arc-shaped recess 214 and a smooth block 215, with a smooth transition between the three. The arc-shaped recess 214 abuts against the port. The side of the arc-shaped recess 214 near the first pin 230 is bonded to a wear-resistant layer 216. The curved contact piece 211 and the bent abutment piece 212 are staggered, with the side of the bent abutment piece 212 near the first pin 230 horizontally aligned with the wear-resistant layer 216. Specifically, when inserted into the port, the gradually curvature design of the curved contact piece 211 (limiting protrusion 213 → arc-shaped recess 214 → smooth block 215) causes the contact piece to deform gradually. The arc-shaped recess 214 conforms to the port surface, the limiting protrusion 213 prevents over-insertion, and the wear-resistant layer 216 reduces frictional loss and improves service life.

[0030] Furthermore, the left and right ends of the frame 100 are hollowed out to form first heat dissipation channels 110. A first spring plate 120 is provided on the side of the first heat dissipation channel 110, and a first elastic protrusion 130 facing inward is formed in the middle of the first spring plate 120, which abuts against the port. The top and bottom ends of the frame 100 are hollowed out to form second heat dissipation channels 140. A second spring plate 150 is provided on the side of the second heat dissipation channel 140, and a second elastic protrusion 160 facing inward is formed in the middle of the second spring plate 150, which abuts against the port. Specifically, after the port is inserted, the elastic protrusions of the spring plates on both sides clamp the outer wall of the port, and the hollowed-out first heat dissipation channel 110 forms an air convection path. The elastic protrusions enhance the fixation of the port and prevent shaking; the left and right heat dissipation channels accelerate heat dissipation and reduce aging caused by high temperatures.

[0031] Furthermore, the upper end of the frame 100 is connected to a cover 170 via a pivot pin, and the left and right ends of the cover 170 are provided with inclined flow deflectors 180. The cover 170 is opened and closed via the pivot pin, and when closed, the inclined flow deflectors cover the opening of the frame 100 to prevent external dust or liquid from splashing in.

[0032] Furthermore, the inner wall of the cover 170 is provided with reinforcing ribs 190. The inner wall reinforcing ribs 190 support the structure of the frame 100 and disperse external pressure.

[0033] Furthermore, the surfaces of the first pin 230 and the second pin 240 are provided with a composite plating layer 250, which includes an underlying nickel plating layer and a surface gold plating layer. The double protection of the plating layer reduces pin corrosion and ensures long-term conductivity stability, making it particularly suitable for high humidity and high salt spray environments.

[0034] 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.
