Arranging of conducting terminal 2 meets the USB3.0 transmission standard, it comprises the first terminal 21 and second terminal 22, first afterbody 213 that the first terminal 21 comprises flat first contact site 211, electrically connect with cable 10 and be connected first contact site 211 and first holding parts 212 of first afterbody 213.Second afterbody 223 that second terminal 22 comprises elasticity second contact site 221, electrically connect with cable 10 and be connected second contact site 221 and second holding parts 222 of second afterbody 223.This first contact site 211 is housed in the first terminal groove 127, second contact site 221 is housed in second terminal groove 128, thereby make win contact site 211 and second contact site 221 be positioned at the below of hyoplastron 12 jointly and form before and after two rows that arrange, this first holding parts 212 is retained in the main part 11 of insulating body 1, second holding parts 222 is retained in the pedestal 5, thereby locating piece 6 matches with pedestal 5 and second terminal 22 can be fixed in the insulating body 1 better.In other embodiments, this first terminal 21 can be inlayed to bury and be molded in the insulating body 1, and this second terminal 22 can be inlayed earlier to bury and together be assembled on the insulating body 1 with pedestal 5 after being molded on the pedestal 5 again.

Please refer to Fig. 2 to shown in Figure 5, fiber device 3 can slide at insulating body 1 upper edge fore-and-aft direction, it is included in the accepting groove 121 of insulating body 1 pedestal 30 that slides along fore-and-aft direction and is installed in optical fiber 35 on the pedestal 30, optical fiber 35 is fixed in the holding slot 112 of insulating body 1, the below of pedestal 30 is provided with the chute 31 that matches with slide block 123, thereby pedestal 30 is slided in accepting groove 121 better, and the front end centre position of pedestal 30 is provided with shelves stops 124 and matches and front wide and rear narrow V-shaped groove 32.Pedestal 30 is respectively equipped with lens 33 in the left and right sides of V-shaped groove 32, optical fiber 35 be installed in lens 33 rear ends with lens 33 optically-coupled, thereby high speed optical signal transmission is provided.Though only demonstrated two lens 33 in the drawings, in other embodiments, pedestal 30 also can be provided with a pair of lens 33 or more lens 33 in the left and right sides of V-shaped groove 32 respectively.Pedestal 30 the both sides of two lens 33 be provided with pilot hole 34 with butt connector (not shown) on cylinder connect, thereby make the center line complete matching of pin connector and socket connector, guarantee the quality of optical signal transmission.The rear end of pedestal 30 is provided with the projection 36 of projection backward, and the front end of spring 4 is fixed on the projection 36, and therefore, this spring 4 is clamped between insulating body 1 and the pedestal 30 to support pedestal 30 forward.

Shell 7 and upper casing 8 common coated insulation bodies 1 are to play shield effectiveness well.Shell 7 comprises the roof 71 that coats hyoplastron 12 tops and be pressed on hyoplastron 12 upper surfaces, the diapire 73 relative with roof 71 and the two side 72 that connects roof 71 and diapire 73.The downward integrated punching of the front end of roof 71 forms a projection 75 that supports above fiber device 3.

When the pin connector insertion has the butt joint socket connector of corresponding fiber device, cylinder on the fiber device of the pilot hole 34 on the fiber device 3 of pin connector and corresponding butt joint socket connector matches, when the length size of pilot hole 34 and cylinder are inconsistent, the fiber device 3 of this pin connector can slide at the acting force lower edge of spring 4 fore-and-aft direction and adjust, thereby makes the fiber device 3 on the pin connector cooperate reliable with fiber device on the corresponding socket connector.In addition, when this fiber device 3 slides backward, pedestal 30 is the front end of compression spring 4 backward, because the rear end of spring 4 is fixed on the reference column 1221 of insulating body 1, the front end of spring 4 can swing up and down above groove 129, thereby when being slided backward, pedestal 30 can swing up and down, therefore, when the cylinder on the fiber device of the pilot hole 34 on the fiber device 3 of pin connector and corresponding butt joint socket connector during, swing up and down in the time of can sliding backward by pedestal 30 and adjust in the initial position misalignment.After pin connector is extracted, pedestal 30 under the acting force of spring 4 to front slide, at this moment, shelves stops 124 supports in the V-shaped groove 32 of pedestal 30 front ends, this stop block 124 of one side is positioned at fiber device 3 front ends and can prevents that fiber device 3 from skidding off accepting groove 121 forward, on the other hand, thus this stop block 124 matches with V-shaped groove 32 on the fiber device 3 and can prevent fiber device 3 rocking on left and right directions.The front end of pedestal 30 top supports on the set projection 75 of shell 7 front ends, the front end of pedestal 30 below supports on the set projection 126 of hyoplastron 12 front ends, therefore, the projection 126 that supports on pedestal 30 all can prevent pedestal 30 rocking at above-below direction with projection 75, in sum, stop block 124, thereby projection 126 and projection 75 all can form and support supporting member can prevent that fiber device 3 from rocking on the direction perpendicular to fore-and-aft direction at fiber device 3, fiber device 3 is returned to virgin state better, thereby the convenient plug connector inserts socket connector once more.

In addition, in other embodiments, the hyoplastron 12 of insulating body 1 also can form in accepting groove 121 projection and support press block above pedestal 30 above the left and right sides of accepting groove 121, thereby prevents fiber device 3 rocking at above-below direction.

The connector 100 that above accompanying drawing disclosed is pin connector, and in other embodiments of the present utility model, this connector 100 also can be socket connector.

In sum, it below only is preferred embodiment of the present utility model, should not limit scope of the present utility model with this, promptly every simple equivalent of doing according to the utility model claims and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
