The present invention is to provide an electrical connector, especially a grounding terminal using a partition assembly to minimize power loop coupling, provide the best waveguide shielding effect, and provide high-efficiency waterproof electrical connectors with front and rear outer shells and front and rear waterproof parts. .

Press, USB Type-C, also known as USB-C, is a hardware interface form of universal serial bus (USB). The biggest feature in appearance is that its upper and lower ends are completely consistent. Compared with Micro-USB, users don’t have to distinguish USB. On the positive and negative side, in terms of function, it can provide a faster transmission rate. Since the release of the USB-C specification in 2014, many new Android mobile devices, notebook computers, desktop computers, and even game consoles and other 3C devices have begun to use this port.

However, the USB Type-C standard connector, due to the substantial increase in the amount of synchronously transmitted data, may generate corresponding electromagnetic radiation during use, which may interfere with the normal operation of other electronic components. In view of this, the industry is constantly researching and developing Methods to improve electromagnetic radiation problems, such as changing the sequence of terminal welding ends to isolate the noise between signal terminals with shielding characteristics. However, this improvement method has been tested to have limited effects and cannot take into account the coupling characteristics of all power circuits. .

In addition, the industry generally uses grounding methods to reduce electromagnetic interference (EMI) generation. For example, a grounded metal partition is set between the upper row of terminals and the lower row of terminals, and the metal partition is contacted with the outer shell by an elastic sheet. Cooperate with the outer shell and the metal partition to isolate the noise. However, whether it is a one-piece metal separator or a multi-piece metal separator, and even the metal separator extends the terminal so that it is located on the outermost sides of the left and right sides of the welding end, the common feature is grounding. Therefore, although it can be It provides the noise isolation effect of the upper and lower terminals, and the noise isolation effect of the connector and the external electronic components, but it does not help the coupling characteristics of the power circuit.

In the past, the electrical connector used as a waterproof related structure, mainly through a waterproof ring made of rubber material, or through a waterproof structure formed after the solidification of waterproof glue. But the electrical connector There are often riveting gaps due to the stamping and forming of metal shells. Therefore, only through structures such as waterproof rings or solidification of waterproof glue, the gaps caused by such riveting cannot be overcome.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the creators of the present invention and the related manufacturers engaged in this industry are eager to study and improve.

Therefore, in view of the above-mentioned deficiencies, the creator of the present invention collected relevant information, evaluated and considered from multiple parties, and based on the accumulated years of experience in this industry, through continuous trials and modifications, he began to design this kind of partition assembly. The grounding terminal minimizes the coupling of the power circuit and provides the best waveguide shielding effect. At the same time, it cooperates with the front and rear housings and the front and rear waterproof parts to provide the patented invention of the electric connector with high efficiency and waterproof.
