Description

Technical Field

[0002] Electronic connectors are mainly used to interconnect different ports between devices, so as to transmit data signals to different devices, such as Type-C connectors. Usually, a shielding iron shell is set inside the electronic connector to protect the electronic components inside the electronic connector from external electromagnetic interference. The shielding iron shell generally wraps the electronic components inside it to form a shielding layer to prevent interference from external electromagnetic waves. At the same time, the shielding iron shell can also reduce the impact of electromagnetic radiation generated by the electronic connector on the outside world, thereby reducing interference in signal transmission and providing a stable and reliable connection. However, the existing shielding iron shell is insulated and connected to the internal structure of the electronic connector, and there are many gaps on the surface of the shielding iron shell. These gaps will weaken the shielding effect of the shielding iron shell, so that external electromagnetic waves will affect the internal electronic components of the electronic connector.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. In the description of the present application, it is necessary to understand that the orientation or position relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0024] The relevant technical personnel of this application have noticed that there is no overlapping contact between the existing on-board Type-C connector shielding iron shell and the Type-C plug connector, that is, the shielding iron shell is insulated and connected to the Type-C plug connector, which greatly reduces the shielding effect of the shielding iron shell on the Type-C plug connector. And due to manufacturing process problems, there are large gaps in the transition interval on the side of the shielding iron shell. External electromagnetic waves can pass through these gaps to interfere with the internal plug connector or other components, thereby affecting the transmission of data signals. Therefore, the relevant technical personnel of this application have added a connection structure to the shielding iron shell in response to the above-mentioned problems, ensuring that the assembled shielding iron shell can form an effective overlap with the Type-C plug connector; at the same time, a bending portion is set in the transition interval on the side of the shielding iron shell, and the gap is covered by the bending portion, thereby effectively enhancing the shielding effect of the shielding iron shell.

[0025] The specific implementation methods of the present application are described below by way of examples:

[0026] like Figures 1 to 4 As shown, the embodiment of the present application provides an electronic connector, including: an outer shell 100, a first inner shell 300, a second inner shell 400 and a plug-in part 200; the outer shell 100 has a first accommodating cavity 110; the first inner shell 300 and the second inner shell 400 are assembled into a second accommodating cavity 800, and at least part of the structure of the first inner shell 300 and the second inner shell 400 is located in the first accommodating cavity 110; at least part of the structure of the plug-in part 200 is located in the second accommodating cavity 800; wherein the first inner shell 300 includes a first connecting part 310, and the second inner shell 400 includes a second connecting part 410, and the first connecting part 310 and the second connecting part 410 are respectively electrically connected to the plug-in part 200 to improve the electronic shielding effect of the first inner shell 300 and the second inner shell 400. Specifically, the outer shell 100 is an integrally formed structure through a mold, and is generally made of plastic. The first accommodating cavity 110 in the outer shell 100 includes a front end, a middle end and an outer end.
