Technical Field
The utility model relates to an electric connector indicates an earth terminal who utilizes baffle subassembly especially, makes power return circuit coupling minimum, provides best waveguide shielding effect, and shell body and front and back waterproof spare provide high-efficient waterproof electric connector around the cooperation simultaneously.
Background
The USB Type-C, also called USB-C, is a hardware interface form of a Universal Serial Bus (USB), and is characterized in that the upper end and the lower end of the USB are completely consistent in appearance, and compared with a Micro-USB, a user does not need to distinguish the front side and the back side of the USB, and functionally, the USB Type-C can provide a faster transmission rate. Since the USB-C specification was released in 2014, many new versions of 3C devices such as Android mobile devices, notebook computers, desktop computers, and even game machines began to use such ports.
However, because the amount of data transmitted in USB Type-C standard is greatly increased, corresponding electromagnetic radiation may be generated during the use process, so as to interfere with the normal operation of other electronic components, therefore, there is a need to develop a method for improving the electromagnetic radiation problem, such as changing the arrangement sequence of the terminal welding ends to isolate the noise between the signal terminals by using the terminals with shielding property.
In addition, the industry generally reduces the generation of electromagnetic interference (EMI) by grounding, for example, a grounded metal partition plate is disposed between the upper row of terminals and the lower row of terminals, and the metal partition plate is contacted with the outer shell by using the elastic sheet, so as to cooperate with the outer shell and the metal partition plate to isolate noise. However, no matter the metal partition plate is a one-piece metal partition plate or a plurality of pieces of metal partition plates, even if the terminals extend from the metal partition plate and are positioned at the outermost sides of the left and right sides of the welding end, the common characteristic is the grounding, so that although the noise isolation effect of the upper and lower rows of terminals and the noise isolation effect of the connector and the external electronic component can be provided, the coupling characteristic of the power circuit is not helpful.
In the related waterproof structure of the conventional electrical connector, a waterproof ring made of rubber or a waterproof structure formed by solidifying waterproof glue is mainly used. However, the electric connector often has a riveted gap due to the punch forming of the metal shell, so that the gap caused by the riveting can not be overcome only by penetrating through the structure such as the waterproof ring or the waterproof glue solidification.
