Description

Technical Field

[0001] The present application relates to a socket connector and an electronic device. Background Art

[0002] The USB Type C interface is a standard interface applicable to the field of consumer electronics, with high-speed transmission and large-current transmission capabilities, and supports the function of plugging in either direction, solving the defects of low transmission rate and non-support for plugging in either direction in existing traditional USB interfaces. However, due to the small size of the USB Type C and the fact that the number of transmission terminals in the standard version reaches 24, the 24 transmission terminals are arranged in two rows corresponding to each other one by one, and a partition is provided between the two rows of transmission terminals.

[0003] Among them, a USB Type C socket generally includes: an insulating body, a plurality of transmission terminals fixed in the insulating body, and a metal shell sleeved on the periphery of the insulating body. The insulating body generally includes a base portion and a tongue portion extending forward from the front end surface of the base portion. The metal shell is sleeved and fixed on the periphery of the base portion. The insulating body and the metal shell jointly enclose and define a plugging space with a forward opening. When a USB Type C plug is inserted into the plugging space, it generally stops when the front end of the USB Type C plug correspondingly hits and impacts the front end surface of the base portion, completing the complete insertion of the plug connector. This will impact and damage the plastic of the base portion of the insulating body.

[0004] Therefore, it is necessary to design a new socket connector to solve the above technical problems. Utility Model Content

[0039] Please refer to Figures 1 to 6 As shown, a socket connector disclosed in the present application is mainly used to be installed inside an electronic device, and the electronic device can be a smart phone, a tablet computer, a laptop computer, a mobile camera, a game console, etc. The socket connector includes: an insulating body 1, a metal shell 2 sleeved and fixed around the insulating body 1, and a plurality of signal terminals 4 fixed inside the insulating body 1. Among them, the insulating body 1 is provided with a base 11 and a tongue portion 12 extending forward from the front end surface of the base 11. The tongue portion 12 includes a tongue root portion 121 integrally connected to the front end surface of the base 11 and a tongue end portion 122 further extending forward from the front end of the tongue root portion 121.

[0040] The metal shell 2 is sleeved and fixed around the base 11 and jointly encloses a docking cavity 20 with an opening at the front end, and the tongue portion 12 protrudes forward in the docking cavity 20 in a cantilever shape. The metal shell 2 is in a ring shape with openings at both ends. In a preferred embodiment, the metal shell 2 is a seamless ring shape with openings at both ends. For example, the metal shell 2 is formed by processing a seamless metal tube, or the metal shell 2 is formed by drawing / stretching a metal plate.

[0041] The signal terminal 4 includes an upper row terminal group (not labeled) composed of a row of several upper terminals (not labeled) and a lower row terminal group (not labeled) composed of a row of several lower terminals (not labeled). Each upper terminal includes an upper fixing section (not labeled) buried and fixed in the base 11, an upper contact section (not labeled) extending forward from the upper fixing section and fixed in the tongue portion 12, and an upper docking section (not labeled) extending backward from the upper fixing section and exposed outside the base. Each lower terminal includes a lower fixing section (not labeled) buried and fixed in the base 11, a lower contact section (not labeled) extending forward from the lower fixing section and fixed in the tongue portion 12, and a lower docking section (not labeled) extending backward from the lower fixing section and exposed outside the base. At least part of each upper contact section is upwardly exposed on the upper surface of the tongue portion 12 to form an upper contact portion, and at least part of each lower contact section is downwardly exposed on the lower surface of the tongue portion 12 to form a lower contact portion. The upper contact portion and the lower contact portion are arranged in a one-to-one mirror symmetry along the up-down direction and are respectively used for realizing signal transmission with a docking plug connector inserted into the docking cavity 20. Further, the upper contact portion and the lower contact portion are correspondingly exposed on the surface of the tongue end portion 122.

[0042] Please refer to Figures 1 to 6 As shown, a receiving groove 110 is formed by downwardly recessing and opening forward at a position near the front end of the upper surface of the base 11 of the insulating body 1. A stop boss 21 is integrally formed by downwardly drawing / stretching at a position corresponding to the receiving groove 110 of the metal shell 2. A process groove 210 is formed by inwardly recessing on the outer surface of the metal shell 2 corresponding to the stop boss 21. At least part of the stop boss 21 is received in the receiving groove 110. When the insulating body 1 fixed with the signal terminal is assembled with the metal shell 2, a preferred implementation is that the stop boss 21 is stopped backward at the inner wall surface of the receiving groove 110. In a further preferred implementation, taking a plane perpendicular to the insertion direction of the docking module as a cross-section, the cross-section of the stop boss 21 is triangular. The distance between the upper surface of the tongue root portion 121 and the inner surface of the metal shell 2 corresponding to the upper surface of the tongue root portion 121 is defined as L1, and the protruding height of the stop boss 21 protruding downward from the inner surface of the metal shell 2 is defined as L2. L2 is greater than half of L1 and less than L1.

[0043] Furthermore, in a preferred embodiment, a receiving groove 110 is formed at the middle position in the left-right direction on each of the upper surface and the lower surface of the base 11. In the up-down direction, the two receiving grooves 110 are arranged in mirror symmetry. Two of the stop bosses 21 are provided and respectively received in the two receiving grooves 110. Further, in the embodiment of the present application, there are also two metal fixing members 3, and the two metal fixing members 3 are respectively fixed in the upper surface and the lower surface of the base 11. The metal fixing member 3 is correspondingly attached to the inner surface of the metal housing 2 and fixed to the metal housing 2 by welding. A relief notch 31 that penetrates in the up-down direction and is open forward is formed at a position near the front end of the metal fixing member 3. The relief notch 31 corresponds to the receiving groove 110 and is used to make way for the stop boss 21.

[0044] Please refer to Figure 3 In the preferred embodiment, the front end face of the stop boss 21 is in a planar shape, and the front end face of the stop boss 21 is flush with the front end face of the base 11. In other embodiments, the front end face of the stop boss 21 can also be designed to protrude forward and be in front of the front end face of the base 11.

[0045] In the solution of the present application, the stop boss 21 is integrally formed by drawing / stretching on the metal housing 2. The stop boss 21 cooperates with the corresponding receiving groove 110 formed on the base 11, which can realize the assembly positioning function. At the same time, when the docking plug connector is inserted into the docking cavity 20, the stop boss 21 can be in contact with the front edge of the plug connector to prevent the over-insertion of the plug connector and prevent the plug connector from damaging the insulating body 1 of the socket connector, especially the base 11 of the insulating body 1. The design that L2 is greater than half of L1 and less than L1 can ensure that the docking plug connector can effectively contact the docking plug connector when inserted into the docking cavity 20. At the same time, it can ensure the stable and accurate assembly positioning between the metal housing 2 and the insulating body 1. On the other hand, the forming method of the stop boss 21 can achieve effective waterproof performance, so that there will be no unnecessary tear holes or tear cracks and other structures on the metal housing 2 due to the need to form the stop boss 21, which will affect the overall waterproof performance. Further, in order to achieve better overall waterproof performance of the socket connector of the present application, the metal housing 2 is integrally designed as a seamless ring, such as formed by processing a seamless metal tube or formed by drawing / stretching a metal plate.

[0046] In addition, the stop boss 21 formed by the solution of the present application has a large overall structural strength and stable structure, and can resist stronger impact force without deformation compared with the traditional bending and tearing stamping structure.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

[0048] Although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
