Description

Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector that can be inserted back and forth.

A related art is disclosed in US Published Patent Application No. 20130095702A1, which discloses a two-way plug connector having a plug connector having opposite upper and lower surfaces, and a plurality of conductive terminals disposed above and below surface. The conductive terminals exposed to the upper and lower surfaces are symmetrically spaced from each other, and the shape of the connector is substantially 180 degrees symmetric so that it can be inserted into the corresponding receptacle connector in the forward and reverse directions. However, the socket connector or the inside of the electronic device needs to be provided with a switching circuit to detect whether the plug connector is inserted in the forward direction or reversely inserted, thereby starting the corresponding subsequent program. The more the terminals of the connector, the more complicated the switching circuit, and thus, the trend is not met. At the same time, the plug connector is an exposed plug, and there is still the possibility of plugging damage in actual use.

The insulative housing includes a body portion and a tongue portion extending forwardly from the body portion, and a latching groove is recessed on both sides of the front portion of the tongue portion. The tongue portion has opposing first and second surfaces. The conductive terminal includes a set of first conductive terminals exposed on the first surface and a set of second conductive terminals exposed on the second surface. The grounded metal piece includes a fixed first in the tongue and spaced apart from the first conductive The plate body of the terminal and the second conductive terminal is provided with a plurality of through holes, and the two side edges of the modified plate body are exposed to the fastening groove. In the prior art, the method of dispensing is commonly used for sealing and waterproofing. However, since the gap between the insulating body and the shielding shell is small, the sealing portion of the level injection may not flow smoothly, thereby failing to accurately close the space requiring waterproofing, resulting in water leakage. Even damage the electrical connector.

Therefore, there is a need for an improved electrical connector to compensate for the above-discussed deficiencies in the prior art.
