Description

Socket connector

The present invention relates to a receptacle connector that can be inserted in both the forward and reverse directions of a corresponding 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 terminals being disposed on the upper and lower surfaces. The conductive terminals exposed to the upper and lower surfaces are symmetrically spaced apart from each other, and the shape of the plug 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 procedure. 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.

A new type of plug connector has emerged. The plug connector can be inserted into the socket connector in both forward and reverse directions. At the same time, the two connectors can transmit high frequency signals. During the continuous development process, various improved plug connections are made. And socket connectors have been born, and the application range is more extensive.

It is an object of the present invention to provide a receptacle connector that can be used not only for a circuit board within an electronic device, but also for other situations.

To solve the above technical problems, the present invention provides a socket connector, a socket connector including a terminal module, a metal case, and a cable. The terminal module includes a rear base, a forwardly extending butt tongue, a terminal, and a shielding plate, and the terminal includes a contact portion and a pin arranged on the butting tongue. The shielding plate is disposed in the docking tongue and has a locking side edge. The metal housing is fixedly wrapped around the rear base and surrounds the butt tongue to form an abutment cavity therebetween. The cable includes a core wire connected to a terminal pin.

Compared with the prior art, the present invention has the following effects: the socket connector of the present invention is connected to a cable, and the use condition of the socket connector can be effectively improved.

An empty plug 226 can insert and pull out the tubular abutting portion 216 in both the forward and reverse directions for preventing dust. Please note that in the actual test, the empty plug 226 will be replaced by the plug connector, the resilient contact portion of the plug connector contacts the terminal strip 208 of the receptacle connector, and the corresponding resilient shield contacts the ground plate 212. The butt tongues 206 are respectively formed with a side edge notch 228 at their opposite side edges for latching with the latch arms of the plug connector. A part of the socket connector of this embodiment is directly constituted by a circuit board, which can save space occupied by the electrical connector. In general, the socket connector is formed of an insulating material and disposed in the notch of the circuit board, thus wasting material that the board removes a portion to form a notch, and at the same time increases the insulating material portion of the socket connector. A pair of grounding plates 212 are directly soldered to the grounding strip 210 of the circuit board 202, so that the process is simplified, and the grounding plate has a certain thickness, which is equivalent to forming a stepped portion of the socket connector at the rear end of the butting tongue.
