New description: [New technical field] The present invention relates to a connector, and more particularly to a connector capable of transmitting optical signals. [Prior Art] The Universal Serial Bus (USB) interface has been widely used in the design of many electronic devices as a standard input/output interface. In 1994, seven world-famous 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 of 1.〇, 2.0 and 3.0, and the USB transfer rate is gradually improving. With the development of the electronics industry and advances in technology, people are still working hard 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. Conductive terminals on the insulative body and fiber optic devices for optical transmission. The insulative housing is provided with a receiving slot, and the optical fiber device can slide in the front and rear direction in the receiving slot, so that the optical fiber device can be rearward in the receiving slot when the USB connector is opposite to the mating connector with the optical fiber device. Sliding, when the USB connector is not docked with the mating connector, the fiber optic device slides forward to restore the original shape, so that it can be easily docked again. However, after the fiber optic device slides in the receiving slot, it is inevitably in the up and down direction, the left and right direction, or the front and rear directions. The skew is created, which is not conducive to the fiber optic device being in contact with the fiber optic device on the docking connector. Therefore, it is necessary to provide a connector having an improved structure to overcome the above drawbacks. [New content] In view of the above, it is necessary to provide a connector that can ensure reliable docking of fiber optic devices. The purpose of the present invention is achieved by the following technical solution: a connector comprising an insulative housing, a conductive terminal held on the insulative housing, and a fiber optic device for optical signal transmission, the insulative housing having an upper surface and a lower surface, the insulating body is provided with a receiving groove recessed from the front side of the lower surface, and an elongated recess 4 M385116 groove recessed from the lower surface and extending in the front-rear direction, and the optical fiber device includes a base sliding in the front and rear direction in the receiving groove And a fiber disposed on the pedestal and extending rearward in the front-rear direction, wherein the pedestal is provided with a lens that is compliant with the optical fiber, and the optical fiber is provided with a coupling portion fixed to the rear side of the lens in the pedestal, and self-coupling The portion extends rearwardly and is positioned in the positioning portion in the elongated recess and the connecting portion connected to the positioning portion.

The upper casing 71 is covered by the tongue plate 14 and includes a bottom wall 711 which is pressed against the lower surface of the tongue plate 14, a top wall 712 opposite to the bottom wall 711, and two side walls 713 which connect the bottom wall π with the top wall 712. The front end of the bottom wall 711 is integrally stamped upward to form a projection 75 that abuts against the fiber unit 3. When the present plug connector 1 is inserted into the mating receptacle connector with the corresponding fiber optic device, the positioning hole 34 on the fiber optic device 3 of the plug connector 100 and the post on the fiber optic device of the corresponding mating receptacle connector When the length of the positioning hole 34 is inconsistent with the cylinder, the optical fiber device 3 of the plug connector 100 can be slid in the front-rear direction under the force of the spring 4 to adjust the optical fiber device 3 on the plug connector 100. The fiber optic device on the corresponding socket connector is flexible and reliable, and the optical fiber 35 is received in the elongated recess 143 and moved in the front-rear direction in the elongated recess 143, so that the optical fiber 35 can be in the initial position and during the active process. Effective control of the system facilitates the overall movement of the fiber optic device 3 without excessive offset. In addition, when the fiber optic device 3 slides backward, the base 3 〇 compresses the front end of the magazine 4 backward, and since the rear end of the spring 4 is fixed on the positioning column of the insulating body ,, the front end of the spring 4 can be in the notch 149 And the lower and lower lions, the rear end can swing up and down in the opening and the upper side to swing up and down when the base 30 slides backward, thereby locating the positioning hole 34 on the optical fiber device 3 of the plug connector 1 corresponding thereto When the cylinder on the optical fiber device of the docking socket connector is misaligned at the initial position, it can be adjusted by swinging up and down or left and right when the base 30 slides backward; when the base 30 is swung up and down or left and right, the rear side of the optical fiber 35 is positioned. In the elongated recess M3 and being pressed by the cover 10 without moving up and down and left and right, the optical fiber device 3 can be effectively restrained, and the optical fiber device 3 can be prevented from excessively swinging and cannot be reliably connected to the optical fiber device of the mating connector. When the plug connector 100 is pulled out, the base 30 slides forward under the force of the spring 4. At this time, the blocking block 145 abuts against the V-shaped groove 31 at the front end of the base 30. On the one hand, the stop The block 145 is located at the front end of the optical fiber device 3 to prevent the optical fiber device 3 from sliding forward out of the receiving groove 141. On the other hand, the blocking block 145 cooperates with the V-shaped groove 31 on the optical fiber device 3 to prevent the optical fiber device 3 from being insulated from the insulating body. 1 Shake in the lateral direction. The lower end of the base 3 abuts against the protrusion 75 provided at the front end 8 of the upper shell, and the front end of the base 30 abuts against the protrusion 147 provided at the front end of the tongue 14 , thereby resisting The bumps 147 and the protrusions 75 on the base 3 can prevent the base from swaying in the up and down direction. As described above, the block 145, the bumps 147 and the protrusions 75 can be formed to resist the optical fiber. The abutting member of the device 3 thus prevents the fiber optic device 3 from swaying in a direction perpendicular to the front-rear direction, thereby better restoring the fiber optic device 3 to the original state, thereby facilitating the plug connector to be reinserted into the receptacle connector. When the optical fiber device 3 is accidentally vibrated, the optical fiber device 3 can be positioned in the elongated recess 143 to pin the base 3〇 to prevent the optical fiber device 3 from being excessive. The swing affects the reliable docking of the fiber optic device with the docking connector. " ^ The drawings and descriptions of the connection (4) and (4) of the age are contact connectors.
