Connector

The present invention relates to a connector, and more particularly to a connector having optical transmission.

The Universal Serial Bus (USB) interface is a standard input/output interface that has been widely used in the design of many electronic devices. In 1994, seven world-renowned computer and communication companies, including Intel, Compaq, Digital, IBM, Microsoft, NEC, and Northern Telecom, jointly established the USB Association (USB-IF) to initially establish a USB interface specification. So far, the USB Association has released versions 1.0, 1.1, 2.0 and 3.0, and the USB transfer rate has gradually improved. With the development of the electronics industry and the advancement of technology, people continue to strive to increase the transmission rate of USB. Currently, there is a USB connector that can transmit optical signals to further increase the transmission rate. The connector usually includes an insulating body and is fixed to a conductive terminal on the insulative housing and a fiber optic assembly for optical transmission. However, when docking different mating plugs (such as docking plugs different from the USB standard), different connectors are required to be docked with them, and if they are arranged, it is not conducive to the simplification of the connector and the miniaturization of the motherboard.

Therefore, it is necessary to modify the conventional connector to overcome the above drawbacks.

The purpose of this creation is to provide a connector that can be selectively plugged into a variety of plugs.

In order to achieve the above object, the present invention adopts the following technical solution: a connector comprising an insulative housing, a conductive terminal mounted on the insulative housing, a fiber optic assembly disposed on the insulative housing, and a shielding housing covering the outer side of the insulative housing. The conductive terminal is provided with a contact portion and a tail portion, and the insulating body is provided with an accommodating space and a tongue plate located in the accommodating space, the tongue plate is provided with a first side and a second side opposite to each other, and the conductive terminal is mounted On the first side and the second side, the optical fiber component is exposed to the accommodating space and located at a side of the tongue.

In order to achieve the above object, the present invention can also adopt the following technical solution: a connector comprising a body, a conductive terminal mounted on the insulating body, a fiber assembly disposed on the insulating body, and a shielding shell covering the outside of the insulating body, The insulative housing is provided with a receiving space and a tongue plate located in the receiving space, the conductive terminal is provided with a contact portion and a tail portion, and the conductive terminal comprises a first terminal group and a second terminal group on one side of the tongue plate And a third terminal group on the other side of the tongue plate, the first terminal group is a USB2.0 terminal, and the first terminal group and the second terminal group together form a USB3.0 terminal, and the third terminal group is The E-Sata terminal is exposed to the accommodating space and located at a side of the tongue.

Compared with the prior art, the conductive terminals and the optical fiber assembly mounted on the first side and the second side of the connector enable the connector to selectively insert different butt plugs, which is advantageous for the arrangement. The simplification of the connector and the miniaturization of the motherboard.
