Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to a plug with a shielding structure. Background Art

[0002] Connectors are important components for new energy vehicles to charge. With the continuous upgrading of electric vehicles, connectors are also constantly being upgraded and optimized. For reasons such as structural compactness, the housing of existing connectors is made to fit as closely as possible to the internal components, which causes the housing of the connector to take on a shape corresponding to the outer contour of the internal components, such as stepped surfaces, rather than a simple flat outer surface.

[0003] A connector includes a plug and a socket that are plugged into each other. For safety in use, a shielding protection structure needs to be provided inside the plug. As disclosed in the publication number CN 118431812 A for a conventional shielding layer structure, the shielding member is a tubular or cylindrical shape with a straight side wall extending, and the shielding layer is embedded in the housing to provide electromagnetic shielding protection. However, when such a shielding layer is provided inside a plug with an uneven outer surface, it cannot be well matched with the housing, especially at the stepped surface structure, which causes a fault in the shielding structure at the stepped surface position, thereby affecting the overall electromagnetic shielding effect and making it easy for electromagnetic leakage to occur at the stepped surface position. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a plug with a shielding structure.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A plug with a shielding structure includes a housing and a core. A shielding housing that matches it is sleeved outside the core. One side of the housing of the core has a first stepped surface, and a socket that matches the first stepped surface is formed on the shielding housing. A shielding insert that matches it is inserted and embedded in the socket to shield the first stepped surface. The shielding insert is fixedly connected to the shielding housing as a whole to jointly form a complete shielding layer outside the core. The inner contour of the housing matches the outer contour of the housing of the core, and a second stepped surface that matches the first stepped surface is formed on the housing. The shielding housing is limited between the housing and the core, and the shielding insert is limited between the second stepped surface and the first stepped surface.

[0026] Such as Figures 1 to 5As shown, the present utility model discloses a plug with a shielding structure, including a housing 1 and a plug core 2. A shielding housing 3 that matches the plug core 2 is sleeved outside the plug core 2. One side of the housing of the plug core 2 has a first stepped surface 201. A socket 301 that matches the first stepped surface 201 is formed on the shielding housing 3. A shielding insert 4 that matches the socket 301 is inserted and embedded in the socket 301 to shield the first stepped surface 201. The shielding insert 4 and the shielding housing 3 are integrally fixed to form a complete shielding layer together for the outside of the plug core 2. The inner contour of the housing 1 matches the outer contour of the housing of the plug core 2. A second stepped surface 101 that matches the first stepped surface 201 is formed on the housing 1. The shielding housing 3 is defined between the housing 1 and the plug core 2, and the shielding insert 4 is defined between the second stepped surface 101 and the first stepped surface 201.

[0027] In this application, the shielding insert 4 is provided to match the housing of the plug core 2 with the first stepped surface 201. The shielding insert 4 and the shielding housing 3 are integrally fixed to form a complete shielding layer to comprehensively wrap the outer wall of the housing of the plug core 1, so as to form an all-round shielding protection effect on the plug core 2, avoid electromagnetic leakage, and ensure the use safety. Among them, the housing of the plug core 2 and the housing 1 are both made of plastic material to play an insulating protection role. The shielding housing 3 and the shielding insert 4 are both made of copper alloy to play a shielding role.

[0028] Specifically, as Figure 1 and Figure 4 shown, the housing of the plug core 2 includes a distal housing 202 and a proximal housing 203. The front side of the distal housing 202 protrudes outward from the proximal housing 203 to form the first stepped surface 201. The shielding housing 3 includes a first shielding housing 302 and a second shielding housing 303. The first shielding housing 302 is sleeved on the outer wall of the distal housing 202, and the second shielding housing 303 is sleeved on the outer wall of the proximal housing 203.

The distal shell 202 is provided with a first recess 204 that matches the first fins 304, and the first fins 304 are locked in the first recess 204.

[0031] At least two second fins 305 extending outwardly and symmetrically are provided on the front side of the second shielding shell 303. A second recess 102 matching the second fins 305 is provided on the inner wall of the shell 1. A group of second fins 305 are individually positioned within the second recess 102. This structure allows the second fins 305 to define the position of the second shielding shell 303 relative to the shell 1.

[0032] Furthermore, the first fins 304 and the second fins 305 extend in opposite directions to enhance the connection stability between the shielding shell 3 and the shell 1 and the ferrule 2 , thereby preventing the shielding shell 3 from being disengaged and ensuring the shielding effect.

These spring clips 308 extend inward at an angle. The spring clips 308 are tilted inward to form multi-point connections with other components, and the spring clips 308 located at the end edges of the first shielding shell 302 and the second shielding shell 303 extend relative to each other.
