Electrical connector

This creation is about an electrical connector, especially an electrical connector with a waterproof function.

The electrical connector is a pipe that provides a signal connection between electronic devices by using a plurality of terminal signal contacts. The commonly used electrical connector interface is a Universal Serial Bus (USB), and is more compact. It is small, easy to carry and widely used by the public. It is commonly used in the connection holes of various portable electronic devices such as smart mobile communication devices and digital cameras, and the corresponding transmission lines are arranged and docked.

In order to facilitate the user to plug in the USB connector in the forward and reverse directions, a manufacturer has developed a socket type electrical connector of the USB Type-C connection interface specification. The Type-C connector includes an insulating body, a plurality of first terminals, and a plurality of The second terminal and the hollow outer casing. The insulating body comprises a base and a tongue extending on one side of the base. Each of the first terminal and the second terminal are disposed on the base and the tongue. The front part of each first terminal is disposed on the upper surface of the tongue, and the rear part is worn. The circuit board is connected outside the base, the front part of each second terminal is disposed on the lower surface of the tongue plate, and the rear part is passed out of the base to connect the circuit board, and the insulating body and the tongue structure are covered by the hollow outer casing. However, the rear side of the hollow casing does not have a waterproof structure that prevents moisture from penetrating from the front side of the hollow casing to the rear side. That is, the rear side of the generally hollow outer casing is not provided with any sealing structure, so that it is behind the insulating body. The possibility of forming a gap with other members causes moisture to penetrate from the gap and affects the application of the electronic product, that is, the board inside the electronic product is damp and affects the operation. Therefore, how to solve the problem of the conventional structure is the problem that the relevant industry must think about and solve.

Conventional connectors do not have a waterproof structure to reduce water vapor penetration, so it is easy to cause the board inside the electronic product to be damp and affect the operation, thus failing to meet the customer's requirements for the barrier of water vapor penetration of the electrical connector.

The shielding plate is disposed in the tongue, and the shielding plate is located between the left surface and the right surface. The plurality of first terminals are disposed on a left surface of the tongue, each of the first terminals has a first soldering leg, and the first soldering leg extends to protrude from the base. The plurality of second terminals are disposed on the right surface of the tongue plate, each second terminal has a second soldering leg, and the second soldering leg extends to protrude from the base portion, and the plurality of first soldering legs of the plurality of first terminals and the second plurality The plurality of second soldering legs of the terminal are disposed symmetrically with respect to the vertical centerline of the tongue. The metal casing surrounds the tongue to form a mating space, the docking space has an opening, the metal casing has a plurality of welded portions, and the welded portions are symmetrically disposed with respect to a vertical center line of the opening. The protection member is covered with a metal casing, and the protection member has a bottom portion. The bottom portion is provided with a socket. The insulation body is inserted into the socket, a gap is formed between the base portion and the bottom portion, and a waterproof rubber layer is disposed on the base portion and the bottom portion to cover the gap.

The electrical connector provided by the present invention is provided with a protective member on the metal casing, and a socket is arranged at the bottom of the protective member, and the insulating body is inserted into the socket to set a waterproof rubber layer. It is placed on the base and the bottom and covers the gap between the base and the bottom. The structural design can solve the problem that the conventional connector can not block the moisture penetration and cause the circuit board to be wet and affect the operation.
