Arranging of conducting terminal 2 meets the USB3.0 transmission standard, and it comprises the first terminal 21 and the second terminal 22, and the first terminal 21 and the second terminal 22 are lined up two rows.

The first afterbody 213 that the first terminal 21 comprises flat the first contact site 211, be electrically connected with cable 10 and be connected the first contact site 211 and the first holding parts 212 of the first afterbody 213.The second afterbody 223 that the second terminal 22 comprises elasticity the second contact site 221, be electrically connected with cable 10 and be connected the second contact site 221 and the second holding parts 222 of the second afterbody 223.This first contact site 211 is housed in the first end pilot trench 127, the second contact site 221 is housed in the second terminal groove 128, thereby so that the first contact site 211 and the second contact site 221 are co-located at the below of hyoplastron 12 and form two rows that arrange in front and back, this first holding parts 212 is retained in the main part 11 of insulating body 1, the second holding parts 222 is retained in the pedestal 5, thereby locating piece 6 matches with pedestal 5 and the 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 first to bury and together be assembled on the insulating body 1 with pedestal 5 after being molded on the pedestal 5 again.

See also Fig. 2 to Fig. 4, fiber device 3 can slide along fore-and-aft direction on insulating body 1, the accepting groove 121 interior pedestals 30 that slide along fore-and-aft direction that it is included in insulating body 1 are installed in two lens 33 on the pedestal 30 and two optical fiber 35 that are connected with lens 33.

The below of pedestal 30 is provided with the chute 31 that matches with slide block 123, thereby makes pedestal 30 better in accepting groove 121 interior slips, and the front end centre position of pedestal 30 is provided with stop block 124 and matches and front wide and rear narrow V-shaped groove 32.Two lens 33 are arranged in respectively the left and right sides of the V-shaped groove 32 of pedestal 30.

Each optical fiber 35 is in holding slot 112 extends into groove 111, this optical fiber 35 is bent to form one and roughly becomes circular-arc flexing section 351, these flexing section 351 pile warp projections, 1110 outsides and be linked to lens 33 rear ends with lens 33 optically-coupled, thereby high speed optical signal transmission is provided.Aforementioned two optical fiber arrange in the mode of staggered cabling in groove 111, make optical fiber 35 that by a relatively large margin distortion be arranged, and are conducive to increase the floating effect of fiber device 3.And the problem that can prevent cable 10 to be stretched and optical fiber is broken occurs.Projection 1110 is between optical fiber flexing section 351.

Although only demonstrated in the drawings two lens 33 and two optical fiber 35 that are connected with these lens, only, in other embodiments, pedestal 30 also can arrange respectively in the left and right sides of V-shaped groove 32 a pair of lens 33 or more lens 33, has simultaneously the optical fiber 35 of some correspondences to be linked to corresponding lens 33.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 this spring 4 is clamped between insulating body 1 and the pedestal 30 to support forward pedestal 30.

Fiber device 3 lays respectively at insulating body with the first terminal 21 and the second terminal 22, and about in the of 1 both sides, and the lens 33 in the pedestal 30 of fiber device 3 are positioned at the place ahead of the first terminal 21 and the second terminal 22.Adopt above-mentioned method for designing, can reduce the volume of whole connector, and make things convenient for the assembling of each assembly.

Shell 7 and upper casing 8 common coated insulation bodies 1 are to provide fine shield effectiveness.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 pin connector inserts butt-joint socket connector with 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 to adjust along fore-and-aft direction under the acting force of spring 4, 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 Compress Spring 4 backward, because the rear end of spring 4 is fixed in the fluting 122 of insulating body 1, the front end of spring 4 can swing up and down above depression 129, can swing up and down when pedestal 30 is slided backward, 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 in the initial position misalignment, swing up and down to adjust in the time of can sliding backward by pedestal 30.After pin connector is extracted, pedestal 30 under the acting force of spring 4 to front slide, at this moment, stop block 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 forward accepting groove 121, 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, the projection 126 that supports on pedestal 30 all can prevent pedestal 30 rocking at above-below direction with projection 75, in sum, thereby stop block 124, projection 126 and projection 75 all can form and support supporting member and can prevent that fiber device 3 from rocking in 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 again.

In addition, in other embodiments, the hyoplastron 12 of insulating body 1 also can form to accepting groove 121 interior projections 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 discloses is pin connector, and in other embodiment of the present invention, this connector 100 also can be socket connector.

Above embodiment has disclosed the photosignal connector by conducting terminal 2 transmission of electric signals and lens 33 transmitting optical signals.And in other embodiments, also can only be used for the transmitting optical signal connector by module compositions such as lens 33 and optical fiber 35.
