Description

Socket connector

The invention relates to a socket 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 terminals being disposed on the upper and lower surfaces. 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 plug connector can not only insert the socket connector in both directions, but also transmit high-speed signals, but inevitable signal interference problems occur.

Therefore, it is necessary to develop a combination of electrical connectors that can improve signal interference.

It is an object of the present invention to provide a socket connector that has a better shielding effect.

The object of the present invention is achieved by the following technical solutions: a socket connector comprising an insulative housing, a terminal, a shielding housing and a metal cover. The insulative housing includes a base portion and a mating tongue, and the terminal includes a contact portion arranged on the mating tongue and a pin extending from the insulative housing. The shielding housing has an abutting portion surrounding the butting tongue, the butting portion and the butting tongue form an abutting cavity, the metal cover is fixed on the outer side of the shielding shell and has a first circuit board supporting leg, the first A circuit board support foot is located on both sides of the abutting portion.

Compared with the prior art, the present invention has the following effects: the shield housing abutment does not have a circuit board support leg, thereby forming an approximately closed shield shell structure, so that the entire connector has a good shielding effect and better strength.
