AI Technical Summary
Conventional USB Type-C socket electrical connectors suffer from detachment or loosening between the iron housing and the main body due to tensile forces during insertion and extraction, leading to potential substrate detachment at the welding location between the plug terminal and the circuit board, affecting conduction.
The socket electrical connector design includes a main body with a base, stepped portion, and tongue plate, combined with a housing that has a mounting space for the base and an accommodation space for the tongue plate, enhancing bonding strength and dispersing insertion forces to prevent deformation of the socket terminals.
This design improves the overall bonding strength, prevents detachment due to long-term use, and reduces the likelihood of substrate detachment, thereby enhancing the stability and durability of the electrical connector during usage.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of connectors, and particularly to a socket electrical connector.
Background Art
[0002] The outer shape, structure, terminal contact method, number of terminals, distance (pitch) between each terminal, and pin assignment of each terminal of the conventional USB Type-C electrical connector are all completely different from those of the current USB electrical connector. The current USB Type-C socket electrical connector includes a plurality of flat terminals provided in a rubber core, and the outside of the rubber core is covered with a structure such as an iron housing.
[0003] After the insertion and extraction of the current Type-C socket electrical connector and the Type-C plug electrical connector, due to the tensile force, when inserted and extracted normally or with excessive force, it is easy to cause detachment or loosening between the iron housing and the main body in the Type-C socket electrical connector. Furthermore, a detachment phenomenon (substrate detachment phenomenon) is likely to occur at the welding location between the plug terminal on the main body and the circuit board, affecting the conduction function of the product.
Summary of the Invention
Problems to be Solved by the Invention
[0004] In view of the problems and defects of the conventional socket electrical connector, in order to improve its problems and defects, the inventor of the present invention provides a new socket electrical connector.
[0005] The first object of the present invention is to provide a socket electrical connector. After combining the main body and the housing, and fitting them to the inner wall surface located in the mounting space by a base, the overall bonding strength is improved, detachment due to long-term insertion and extraction can be avoided, and the detachment phenomenon occurring at the welding location between the plug terminal and the circuit board can be effectively improved, enhancing the stability and durability during the use of the product.
[0006] The second object of the present invention is to provide an outlet electrical connector. When the plug electrical connector is inserted into the insertion space, the end of the plug electrical connector contacts the stop wall, and the housing (iron housing) contacts the plug electrical connector. When the plug electrical connector is inserted to the innermost part of the insertion space, the force is dispersed to the housing, avoiding the collision of the main body, and ensuring that a plurality of outlet terminals on the main body are not pressed and deformed.
Means for Solving the Problems
[0007] To achieve the above object, the present invention provides an outlet electrical connector, including a main body, a plurality of outlet terminals, a housing, and a cover. The main body includes a base, a stepped portion located on one side of the base, and a tongue plate extending externally from one side of the stepped portion. The thickness of the base is greater than that of the tongue plate. Each of the outlet terminals is provided on the main body, and a part of it is exposed on one surface of the tongue plate. The inner wall surface of the housing defines an accommodation space and a mounting space located on one side of the accommodation space and communicating with each other. The distance between the inner wall surfaces located in the accommodation space is greater than the distance between the inner wall surfaces located in the mounting space. The mounting space accommodates the base and is attached to the inner wall surface located in the mounting space. The accommodation space accommodates the tongue plate and a part of the stepped portion. The tongue plate protrudes from the accommodation space. An insertion space is defined between the inner wall surface located in the accommodation space and the tongue plate and a part of the stepped portion. The cover covers the outside of the housing.

Modes for Carrying Out the Invention
[0009] As shown in FIGS. 1, 2 and 3, each is a schematic plan view of an embodiment of the present invention, a schematic cross-sectional structure view of the A-A cross-sectional line in FIG. 1 and a three-dimensional exploded schematic view. The present invention is a socket electrical connector, and the socket electrical connector 1 mainly includes a main body 10, a plurality of socket terminals 11, a housing 12 and a cover 13.
[0010] The main body 10 includes a base 100, a stepped portion 102 and a tongue plate 104. The thickness of the base 100 is larger than that of the tongue plate 104, and the thickness of the stepped portion 102 is the same as that of the base 100. Each socket terminal 11 is provided on the main body 10, and a part of it is exposed on one surface of the tongue plate 104. In particular, due to the shielding region 106 defined between the stepped portion 102 and the tongue plate 104, each socket terminal 11 is not exposed and is embedded in the main body 10. When a plurality of plug terminals (not shown) of the plug electrical connector come into contact with and rub against the plurality of socket terminals 11 of the socket electrical connector 1 respectively, due to friction, metal debris is generated from the terminals. After the insertion and extraction of the plurality of socket terminals 11 and the plurality of plug terminals, the metal debris is prevented from being accumulated in the shielding region 106. Furthermore, problems such as poor withstand voltage or short circuit of contact between the adjacent plurality of socket terminals 11 and the plurality of plug terminals are avoided.
[0011] The inner wall surface 120 of the housing 12 defines a receiving space 121 and a mounting space 122 respectively. The distance a between the inner wall surfaces 120 located in the receiving space 121 is larger than the distance b between the inner wall surfaces 120 located in the mounting space 122. The mounting space 122 houses the base 100 and is attached to the inner wall surface 120 located in the mounting space 122. The receiving space 121 houses the tongue plate 104 and a part of the stepped portion 102. An insertion space 123 is defined between the inner wall surface 120 located in the receiving space 121 and the tongue plate 104 and a part of the stepped portion 102. After combining the main body 10 and the housing 12, by attaching the base 100 to the inner wall surface 120 located in the mounting space 122, the overall bonding strength can be improved, and detachment due to long-term insertion and extraction can be avoided.
[0012] Further, the housing 12 is located between the accommodation space 121 and the mounting space 122 and extends to the retaining wall 124 on the surface of the base 100 so as to be bent inward. When a plug electrical connector (not shown) is inserted into the insertion space 123, the end of the plug electrical connector contacts the retaining wall 124, and the housing 12 (made of iron) contacts the plug electrical connector. When the plug electrical connector is inserted to the deepest part of the insertion space 123, the force is dispersed to the housing 12, avoiding the main body 10 from being impacted, and ensuring that the plurality of socket terminals 11 on the main body 10 are not pressed and deformed.
