[0003] Common copper jacks for on-board charging plugs currently on the market suffer from issues such as poor structural design, poor sealing, and inefficient processing. These issues not only shorten the lifespan of the plugs but can also allow impurities such as rainwater and sand to enter the plugs, damaging internal components and posing safety risks. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a self-sealed stamped copper charging socket, which overcomes the shortcomings of the existing technology. By setting a sealing plug to seal at the front end of the male pin, it effectively prevents water, dust and other impurities in the environment from entering the charging plug when the charging connection plug is exposed to the air and causing damage to the internal parts of the vehicle-end charging plug.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

The conductive contact is fixedly connected to the front end of the male pin guide hole column, the crimping cable groove is fixedly connected to the rear end of the male pin guide hole column, and a sealing plug is fixedly connected in the middle of the male pin guide hole column.

[0007] Preferably, an injection-molded through hole is provided in the middle of the male needle guide hole column, and the sealing plug passes through the injection-molded through hole by injection molding and is connected to the male needle guide hole column as a whole.

[0008] Preferably, the conductive contact member includes a plurality of contact springs, the ends of which are connected to the front end surface of the male needle guide hole column, and the plurality of contact springs are closely arranged in a centrally symmetrical manner to form a conductive socket.

[0009] Preferably, three sealing strips are provided on the outer surface of the sealing plug.

[0010] Preferably, the copper jack body is made of a copper plate by punching through a mold to form a cylindrical structure, and the sealing plug is made of a rubber material.

[0012] This utility model provides a self-sealing stamped copper charging jack. It offers the following advantages: By providing a sealing plug at the front end of the male pin, it effectively prevents water, dust, and other impurities from entering the charging plug when exposed to air, potentially damaging the internal components of the vehicle-side charging plug. Furthermore, through injection molding, the sealing plug and the male pin guide post are integrated into a single structure, effectively preventing the sealing plug from separating from the copper jack body during assembly.

[0018] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0019] Example 1, as Figures 1 to 2 As shown, a self-sealed stamped charging copper jack includes a copper jack body, which includes a conductive contact 1, a male needle guide hole column 2 and a crimping cable groove 3. The conductive contact 1 is fixedly connected to the front end of the male needle guide hole column 2, the crimping cable groove 3 is fixedly connected to the rear end of the male needle guide hole column 2, and a sealing plug 4 is fixedly connected in the middle of the male needle guide hole column 2.

[0020] Working principle:

[0021] During use, the cable is crimped into the crimping groove 3, creating a conductive connection. When the male pin of the charging gun is inserted into the copper jack, the conductive contact 1 guides it into the male pin guide hole 2, enabling charging. Simultaneously, a sealing plug 4 seals the tip of the male pin, effectively preventing moisture, dust, and other impurities from entering the charging connector when exposed to air, potentially damaging the internal components. This effectively protects the internal components of the vehicle-side charging plug from moisture and dust, extending its service life.

[0022] In Example 2, a further preferred embodiment of Example 1, an injection-molded through-hole 5 is provided in the center of the male needle guide post 2. The sealing plug 4 is directly injection-molded through the injection-molded through-hole 5 and integrated with the male needle guide post 2, forming an integrated structure. This effectively prevents the sealing plug from separating from the copper jack body during assembly.

[0023] In Example 3, as a further preferred embodiment of Example 1, the conductive contact 1 includes multiple contact springs, each of which has its end connected to the front end of the male pin guide post 2. The multiple contact springs are arranged symmetrically and closely to form a conductive receptacle. The multiple contact springs cooperate to clamp the conductive contact 1 and the male pin of the charging gun, effectively ensuring stable contact.

[0024] Embodiment 4, as a further preferred embodiment of embodiment 1, is provided with three sealing strips on the outer surface of the sealing plug 4, and the three sealing strips are evenly arranged on the outer ring of the sealing plug 4, thereby effectively improving the sealing performance of the copper jack.

[0025] In Example 5, as a further preferred embodiment of Example 1, the copper jack body is formed into a cylindrical structure by continuously stamping a copper plate through a die. This simplifies the manufacturing process of the copper jack body, thereby improving processing efficiency and saving materials. The sealing plug 4 is made of a high-performance rubber material that is corrosion-resistant and high-temperature-resistant, effectively ensuring the service life of the sealing plug 4 itself.

[0026] Embodiment 6, as a further preferred embodiment of embodiment 1, a silver-plated layer is provided on the outer surface of the copper jack body. By plating the silver-plated layer on the outer surface of the copper jack body, the corrosion resistance of the copper jack body is effectively guaranteed.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
