Description

Technical Field

[0001] The utility model belongs to the technical field of electrical connection structures, and particularly relates to a high-current connector. Background Art

[0002] With the synchronous leap of society and technology, the standardization and normalization of electronic components have become an industry trend, which has given birth to the revolutionary USB Type-C interface standard. This innovative interface not only ends the chaos in the design of traditional USB interfaces, but also quickly wins the favor of the market with its high-efficiency performance of integrating charging and data transmission, as well as its small size, fast charging speed, and convenience of being pluggable on both sides.

[0003] In the design of the USB Type-C interface, a key structure is the middle section piece located between the upper and lower contacts. This component not only provides a stable physical support for the contacts, but also plays an important electrical isolation function. Under repeated plugging and unplugging operations, the middle section piece bears the main mechanical stress. Therefore, in order to ensure sufficient durability and strength, the middle section piece often needs to maintain a certain thickness. However, due to strict overall size limitations, this poses a challenge to the material thickness of the upper contacts - being too thin may affect stability and safety under high-current and high-power applications; while if the contact thickness is increased to meet high-load requirements, it is necessary to reduce the thickness of the middle section piece, which may weaken its structural strength and is prone to wear or breakage during long-term use, affecting the service life and reliability of the interface. Summary of the Utility Model

[0004] In view of the above existing technical problems, the utility model provides a high-current connector to solve the problem that the existing USB Type-C interface cannot withstand high current and high power. While meeting a relatively high plugging and unplugging strength, the high-current connector improves the applicability to high current.

[0005] The utility model provides a high-current connector, which includes a housing, a middle section piece, a first terminal, a second terminal and an insulating seat. The insulating seat is arranged in the housing, and the lower part of the insulating seat is exposed outside the housing. The housing is provided with a socket, and the middle section piece is located inside the socket. The middle section piece includes a plate-shaped part and a reinforcing edge integrally formed. The reinforcing edge is disposed around the end edge and the two side edges of the plate-shaped part close to the socket. The thickness of the reinforcing edge is greater than that of the plate-shaped part. The number of the first terminals and the second terminals is multiple. One ends of the multiple first terminals are spaced on the upper surface of the plate-shaped part and extend to the end of the plate-shaped part close to the socket. The other ends of the multiple first terminals pass through the insulating seat and are exposed below the housing. One ends of the multiple second terminals are spaced on the lower surface of the plate-shaped part and extend to the end of the plate-shaped part close to the socket. The other ends of the multiple second terminals pass through the insulating seat and are exposed below the housing.

[0006] Further, the end of the middle section piece away from the socket is inserted into the insulating seat.

[0007] Further, the housing body includes an annular part and a plug-in housing. The middle section piece, the first terminal, the second terminal and the insulating seat are covered in the annular part, and the plug-in housing is covered on the outer periphery of the annular part.

[0008] This high-current connector adopts an innovative strategy in design, that is, a reinforcing edge is arranged around the core component - the middle section piece. The thickness of the reinforcing edge exceeds that of the plate-shaped part. Such a design can significantly enhance the structural stability of the middle section piece and provide additional mechanical support. In actual plugging and unplugging operations, the reinforcing edge can effectively disperse and absorb the externally applied force and has excellent anti-wear ability. In this way, the pressure borne by the plate-shaped part is reduced, and the requirement for its material strength is also correspondingly reduced. Therefore, the designer can reduce the thickness of the plate-shaped part without affecting the overall structural integrity, and instead thicken the first terminal and the second terminal to meet the high-current transmission requirements, thereby improving the power-carrying capacity and durability of the entire connector. This design cleverly balances the structural strength and the current-carrying capacity, providing the possibility for the application of the connector in a high-intensity current environment.

[0014] See Figure 1 and Figure 2 As shown, the present utility model discloses a high-current connector, which includes a housing, a middle section piece 2, a first terminal 9, a second terminal 7 and an insulating seat 5. The insulating seat 5 is arranged in the housing, and the lower part of the insulating seat 5 is exposed from the housing. The housing is provided with an insertion port 1. The middle section piece 2 is located inside the insertion port 1. The middle section piece 2 includes an integrally formed plate-like part 6 and a reinforcing edge 8. The reinforcing edge 8 is arranged around the end edge and its two side edges of the plate-like part 6 close to the insertion port 1. The thickness of the reinforcing edge 8 is greater than the thickness of the plate-like part 6. The number of the first terminals 9 and the second terminals 7 is multiple. One ends of the multiple first terminals 9 are spaced on the upper surface of the plate-like part 6 and extend to the end of the plate-like part 6 close to the insertion port 1. The other ends of the multiple first terminals 9 pass through the insulating seat 5 and are exposed below the housing. One ends of the multiple second terminals 7 are spaced on the lower surface of the plate-like part 6 and extend to the end of the plate-like part 6 close to the insertion port 1. The other ends of the multiple second terminals 7 pass through the insulating seat 5 and are exposed below the housing.

[0015] The end of the middle section piece 2 away from the insertion port 1 is inserted into the insulating seat 5.

[0016] The housing body includes an annular part 1 and a plug-in housing 4. The middle section piece 2, the first terminal 9, the second terminal 7 and the insulating seat 5 are covered in the annular part 1, and the plug-in housing 4 is covered on the outer periphery of the annular part 1.

[0017] This high-current connector adopts an innovative strategy in its design. That is, an enhanced edge 8 is provided around the middle section piece 2, which is the core component. The thickness of the enhanced edge 8 exceeds that of the plate-like part 6. Such a design can significantly enhance the structural stability of the middle section piece 2 and provide additional mechanical support. During actual plugging and unplugging operations, the enhanced edge 8 can effectively disperse and absorb the externally applied force and has excellent anti-wear ability. As a result, the pressure borne by the plate-like part 6 is reduced, and the requirement for its material strength is also correspondingly lowered. Therefore, the designer can reduce the thickness of the plate-like part 6 without affecting the overall structural integrity and instead thicken the first terminal 9 and the second terminal 7 to meet the high-current transmission requirements, thereby improving the power-carrying capacity and durability of the entire connector. This design cleverly balances the structural strength and the current-carrying capacity, making it possible for the connector to be applied in a high-intensity current environment.
