This application claims the priority benefit of China patent application serial no. 202111375028.X, filed on Nov. 19, 2021. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
The disclosure relates to an electrical connector.
With the advance of technology, various connectors for different electronic products have emerged, among which the electrical connector adapted for cables is one of the most ubiquitous connectors. Currently, the type-C connector is a connector widely used for cables as it realizes positive and negative insertion. However, the terminals in the existing type-C connector are disposed on the inner side of the connector housing, making the coplanarity degree of arc height of the terminals relatively unstable and the true position of the terminal-related elements difficult to be controlled. Such design therefore requires the metallic sheet for the terminals to undergo a second shaping processing.
The disclosure provides an electrical connector capable of controlling effectively the coplanarity degree of arc height of the terminals and reducing the manufacturing difficulty by stacking the elements.
The electrical connector of the disclosure includes an inner housing, two first components, a plurality of terminals, two second components, two metallic sheets, and an outer housing. The inner housing has a insertion space, an inner wall surface, an outer wall surface, and a plurality of first openings. The inner wall surface faces toward the insertion space. The outer wall surface faces away from the insertion space. The first openings connect the inner wall surface and the outer wall surface. The terminals are respectively disposed in the first component and assembled to the outer wall surface along with the first components. Connecting ends of the terminals extend from the outer wall surface through the first opening to the insertion space. The second components are assembled to the inner housing and shield the connecting ends and the first openings. The metallic sheets are assembled to the inner housing and stacked on the second components. The outer housing accommodates the inner housing, the terminals, the first components, the second components, and the metallic sheets.
The electrical connector of the disclosure includes an inner housing, two first components, two terminal module, and an outer housing. The inner housing has a insertion space, an inner wall surface, an outer wall surface, and a plurality of first openings. The inner wall surface faces toward the insertion space. The outer wall surface faces away from the insertion space. The first openings connect the inner wall surface and the outer wall surface. Each terminal module comprises a first component and one set of terminals, and each terminal module is disposed on the outer wall surface of the inner housing. A plurality of connecting ends of the terminals extend from the outer wall surface through the first openings to the insertion space, and another electrical connector is suitable to be inserted into the insertion space along an insertion axis and connected with the connecting ends. The outer housing accommodates the inner housing, the terminals, and the two first components.
In an embodiment of the disclosure, the two first components, the two second components, the two metallic sheets, and the terminals are disposed symmetrically with respect to the inner housing.
In an embodiment of the disclosure, a gap exists between the first components and the inner housing along the insertion axis, and the second components fill the gap.
In an embodiment of the disclosure, the second components are structurally connected subsequently between the first components and the inner housing.
In an embodiment of the disclosure, the first components have a positioning protrusion, the inner housing has a first positioning groove, and the positioning protrusion is fitted into the first positioning groove.

Based on the above, in the electrical connector of the disclosure, the first components of an insulator is disposed in the inner housing and partially overlapped on the outer wall surface, and the connecting ends of the terminals extend to the insertion space through the first openings of the inner housing, then the second components is assembled to the outer wall of the inner housing and shields the first openings and the connecting ends, and the metallic sheets are disposed on the outer wall surface of the inner housing and stacked on the second components. Accordingly, these elements may apply a pressure in advance on the terminals during assembly and allow the part where these terminals extend into the insertion space to have good coplanarity degree of arc height due to the overlap of the elements, such that the true position of the elements related to the terminals in the electrical connector may be controlled effectively during the production, and the difficulty in producing the elements related to the terminals in the electrical connector may be reduced, improving the production yield of the electrical connector.
