Description

Technical Field

[0001] This utility model belongs to the technical field of electric vehicle charging sockets, and in particular relates to a charging interface socket with a metal locking structure. Background Technology

[0002] Currently, most electric vehicle charging docks use a plastic shell locking structure, where a locking groove is directly formed on the plastic shell. This groove is then connected and fixed by a buckle on the charging gun. However, for charging docks that need to withstand frequent plugging and unplugging, the buckle on the charging gun and the locking groove wear down due to frequent contact, which can easily lead to loosening or breakage. This results in insufficient charging connection tightness and poses a safety hazard. Summary of the Invention

[0003] The purpose of this utility model is to provide a charging interface socket with a metal locking structure that enhances structural strength and improves connection reliability.

[0004] This utility model is achieved by the following technical solution: A charging interface socket with a metal locking structure includes: The socket body has a plug interface and a plug protrusion extending around the plug interface; A metal fastener is integrally injection molded onto the outer wall of the insertion protrusion ring. The metal fastener has a snap-fit ​​through hole. When the metal fastener is integrally injection molded onto the outer wall of the insertion protrusion ring, the snap-fit ​​through hole and the insertion protrusion ring form a snap-fit ​​groove.

[0005] As described above, a charging interface socket with a metal locking structure has L-shaped steps on both sides of the metal locking component.

[0006] As described above, a charging interface socket with a metal locking structure has a first injection molding groove extending downward along the upper surface on both sides of the metal locking component.

[0007] As described above, a charging interface socket with a metal locking structure has injection molding steps extending outward along the first injection molding groove on both sides of the metal locking component.

[0008] As described above, a charging interface socket with a metal locking structure has a second injection groove extending upward along the lower surface at the front end of the metal locking component.

[0009] As described above, a charging interface socket with a metal locking structure has an injection molding fixing groove at the bottom of the metal locking component, which is connected to the card-connecting through hole and the second injection molding groove respectively.

[0010] As described above, a charging interface socket with a metal locking structure has rounded corners on the edge of the opening corresponding to the through hole on the metal locking clip.

[0011] As described above, a charging interface socket with a metal locking structure is provided, wherein the metal locking component is made of aluminum alloy.

[0012] Compared with the prior art, the present invention has the following advantages: This utility model provides a charging interface socket with a metal locking structure, including a socket body and a metal locking component with a snap-fit ​​hole. The socket body has a plug interface and a plug-fit protrusion extending along the periphery of the plug interface. The metal locking component is integrally injection molded onto the outer wall of the plug-fit protrusion. When the metal locking component is integrally injection molded onto the outer wall of the plug-fit protrusion, a snap-fit ​​groove is formed between the snap-fit ​​hole and the plug-fit protrusion. During use, when the charging gun is inserted into the plug interface, the snap-fit ​​protrusion on the charging gun abuts against the upper surface of the metal locking component and is locked in the snap-fit ​​groove. By integrally injection molding the metal locking component onto the plug-fit protrusion and engaging with the snap-fit ​​protrusion on the charging gun through the snap-fit ​​hole on the plug-fit protrusion, the loosening or breakage caused by frequent contact wear of the snap-fit ​​groove on the original plastic socket body can be avoided, thereby enhancing structural strength and improving connection reliability.

[0016] Specific embodiments, such as Figure 1-4 A charging interface socket with a metal locking structure is shown, comprising: a socket body 1, on which a plug interface 2 is provided, and a plug-in protrusion 3 extending along the periphery of the plug interface 2; a metal locking member 4, integrally injection molded on the outer wall of the plug-in protrusion 3, the metal locking member 4 having a snap-fit ​​through hole 5, wherein when the metal locking member 4 is integrally injection molded on the outer wall of the plug-in protrusion 3, the snap-fit ​​through hole 5 and the plug-in protrusion 3 form a snap-fit ​​groove 6. In use, during the insertion of the charging gun 100 into the plug interface, the snap-fit ​​protrusion 101 on the charging gun 100 abuts against the upper surface of the metal locking member 4 and is engaged in the snap-fit ​​groove 6. The integral injection molding of the metal locking member onto the plug-in protrusion, through the snap-fit ​​through hole on the plug-in protrusion and the snap-fit ​​protrusion on the charging gun, avoids loosening or breakage caused by frequent contact wear of the snap-fit ​​groove on the original plastic socket body, thus enhancing structural strength and improving connection reliability. When locked, the load on the metal locking fastener can be evenly distributed on both sides of the symmetrical structure, avoiding deformation or wear caused by stress concentration on one side.

[0017] Specifically, the metal locking member 4 has L-shaped steps 7 on both sides. This increases the holding force of the metal locking member 4 on the plastic part, making the connection between the metal locking member 4 and the socket body 1 more secure.

[0018] In addition, in order to further improve the connection stability between the metal fastener 4 and the socket body 1, the metal fastener 4 is provided with first injection grooves 8 extending downward along the upper surface on both sides.

[0019] Furthermore, in order to further improve the connection stability between the metal fastener 4 and the socket body 1, the metal fastener 4 is provided with injection molding steps 9 extending outward along the first injection molding groove 8 on both sides.

[0020] More specifically, in order to further improve the connection stability between the metal fastener 4 and the socket body 1, the front end of the metal fastener 4 is provided with a second injection groove 10 extending upward along the lower surface.

[0021] Furthermore, the bottom of the metal fastener 4 is provided with an injection molding fixing groove 11, which is connected to the snap-fit ​​through hole 5 and the second injection molding groove 10 respectively. By providing the injection molding fixing groove 11, it is convenient to fix the metal fastener 4 during the injection molding of the metal fastener 4 and the socket body 1, thereby improving the production quality.

[0022] Furthermore, the metal locking fastener 4 has a rounded corner 12 at the edge of the opening corresponding to the snap-fit ​​hole 5. By setting the rounded corner 12, it is easy for the snap-fit ​​protrusion on the charging gun to snap into the snap-fit ​​groove 6.

[0023] Specifically, the metal locking component 4 is made of aluminum alloy. The metal locking component 4 made of aluminum alloy has strong plasticity and is easy to process into the card-connecting through hole 5, L-shaped step 7, first injection groove 8, injection step 9, and second injection groove 10 required in this application; it is also corrosion-resistant, does not easily rust in daily use, and has low maintenance costs.

[0024] Specifically, this application can make improvements to the charging interface socket disclosed in patent application publication number CN219534914U.
