Plug connector

This creation relates to a plug connector.

U.S. Patent Application Publication No. 20130095702A1 discloses a two-way plug connector having a plug connector having opposing upper and lower surfaces, the plurality of conductive socket terminals being disposed on the upper and lower surfaces. The conductive socket 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 socket 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 socket 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.

Our company actively develops new plug connectors that can be inserted into the socket connector in both directions. The two connectors can transmit high-frequency signals. In the continuous development process, we have developed electromagnetic interference and RF. Interfering plug connector and socket connector.

The purpose of this creation is to provide a plug connector that has a good function of preventing signal interference.

The purpose of the present invention is achieved by the following technical solutions: a plug connector comprising an insulative housing, a shielding shell attached to the outside of the insulative housing, and two rows of terminals, the insulative housing is provided with a forwardly extending docking chamber and a through-and-out chamber The terminal slots on the two sides, the terminal includes an elastic contact portion received in the terminal slot and protruding into the mating cavity, and the latching arms are respectively disposed on lateral sides of the mating cavity. The plug connector further includes a grounding member and an insulating film sandwiched between the insulating body and the shielding case. The insulating body is provided with a through groove in front of the terminal slot, and the grounding member is provided with a front elastic region protruding forwardly through the through groove and protruding into the docking cavity. The insulating film is attached to the terminal groove to insulate the elastic contact portion of the terminal from the shielding case from each other.

Compared with the prior art, the creation has the following effects: the setting of the grounding member can better prevent the high frequency signal from being disturbed.
