Description

  The present invention particularly relates to an electrical connector that is waterproof and has a small metal cover volume.

  USB is usually used for exchanging data between electronic devices such as digital cameras, mobile phones, portable media players, mice, keyboards, USB memory and personal computers. In other words, USB is currently used by the PC industry and other consumption. This is the serial bus with the widest range of applications for the electronics industry. As the capacity of flash memory has increased, the USB transfer speed has also been upgraded. Currently, USB has already been upgraded from 2.0 to 3.0, and theoretically speaking, the transfer speed of USB 3.0 is about 10 times that of USB 2.0, and the volume of the USB connector has been further reduced. In order to prevent liquid from entering the inside of the electronic product during the use process, a waterproof function is generally designed for the female connector of the micro USB mounted on the electronic product. A USB female connector with a general waterproof function encloses a plastic insertion support terminal block, a plurality of terminals mounted on the insertion support terminal block, and a insertion support terminal block. A metal cover for covering and a plastic waterproof cover body for covering the outside of the metal cover body are provided.

  Due to the necessity of design and assembly, when the above-described USB female connector is attached near the antenna inside the mobile phone, the metal cover of the USB female connector affects the function of the antenna of the mobile phone. However, since the metal cover of the USB female connector is an indispensable part in order to ensure the attachment / detachment function of the USB female connector and the USB male connector, the USB cover can be waterproof and the metal cover has a small volume. A side connector is required.

  An object of the present invention is to provide an electrical connector that can be waterproofed and has a small metal cover against the shortcomings of the prior art described above.

  In order to achieve the above-described object, the electrical connector provided by the present invention is used to insert the connection connector, and includes a clamping member on each side of the connection connector. The electrical connector includes a plastic terminal block, a plurality of terminals mounted on the terminal block in a mold, a first insulating cover body covering the periphery of the terminal block, and a rear end of the first insulating cover body And a metal cover body molded into the first insulating cover body in the mold. On the front surface of the first insulating cover body, a rearward connection port is opened. On the metal cover body, an upper cover is formed by press-molding a storage cover in the upward direction on both sides, and a penetration corresponding to the storage cover is provided on both sides. A lower cover provided with a groove is provided, and the upper cover and the lower cover are both plate-shaped, welded, and connected to the through groove and the connection port. When connecting the electrical connector and the connection connector, the clamping member of the connection connector sandwiches the through-groove portion and is inserted into the housing cover.

  As described above, the electrical connector seals the electrical connector by attaching the first insulating cover body to the peripheral side surface of the terminal block and molding the second insulating cover body in the mold at the rear end of the first insulating cover body. And achieve a waterproof effect. In addition, the metal cover body is formed by joining the plate-shaped upper cover and lower cover by laser welding, and then molding the first insulating cover body in the mold, the lower surface of the lower cover and the upper surface of the connection port are flat. The housing cover of the upper cover is coated on the through groove of the lower cover, and the through groove is connected to the connection port. When connecting the electrical connector and the connection connector, the clamping member of the connection connector sandwiches the through-groove portion and is contained in the housing cover, and the volume of the metal cover body is relatively small. It is an electrical connector with less obstacles.

  The electrical connector of the present invention is waterproof, has a small metal cover volume, and has an effect that there are few obstacles to the antenna signal compared to the prior art.

It is a three-dimensional view regarding the electrical connector of the present invention. It is a three-dimensional exploded view of the electrical connector shown in FIG. It is a three-dimensional view of the 1st insulation cover body of the electrical connector shown in FIG. FIG. 3 is a three-dimensional view of a state in which the electrical connector shown in FIG.
