Embodiment

Refer to Fig. 1, a kind of joints of optical fibre 100 that embodiment of the present invention provides, arrange on the circuit board 200 of an electronic installation (such as computing machine), for realizing the signal transmission between this circuit board 200 and external connected electronic device (such as USB flash disk).

As shown in Figures 2 and 3, these joints of optical fibre 100 comprise a body 10, a plurality of optical fiber group 30 and a plurality of slot 50.This body 10 comprises a plurality of optical transceiver modules 13 and opto-electronic conversion lens 14.

The plurality of optical transceiver module 13 is arranged on this circuit board 200.The plurality of optical transceiver module 13 is located along the same line.Each optical transceiver module 13 comprises a light emitting module 131 and a receipts optical module 132.This light emitting module 131 is for the utilizing emitted light signal, and this receives optical module 132 for receiving optical signals.This light emitting module 131 in each optical transceiver module 13 and the adjacent setting of this receipts optical module 132.

These opto-electronic conversion lens 14 comprise a rectangular-shaped pedestal 140, a plurality of the first collector lens 146, a plurality of the second collector lens 147 and a catoptron 148.Offer an accommodating cavity 141 in this pedestal 140.The plurality of optical transceiver module 13 is contained in this accommodating cavity 141.This accommodating cavity 141 comprises a roof 142 be oppositely arranged with this circuit board 200 and a sidewall 143 vertical with this roof 142.This roof 142 comprises a 142a of the inside surface towards this circuit board 200.This sidewall 143 comprises an outside surface 143a.It is upper that the plurality of the first collector lens 146 arranges this inside surface 142a, and it is upper that the plurality of the second collector lens 147 is arranged on this outside surface 143a, and corresponding one by one with this first collector lens 146.

The plurality of optical fiber group 30 is corresponding one by one with the plurality of optical transceiver module 13 respectively.The plurality of slot 50 is corresponding one by one with the plurality of optical fiber group 30 respectively.Concrete, an end of each optical fiber group 30 is by corresponding the second collector lens 147 docking of coupling arrangement 31 and corresponding optical transceiver module 13; The other end of each optical fiber group 30 connects with corresponding slot 50.Each optical fiber group 30 comprises two optical fiber 30a, and with this light emitting module 131 of corresponding optical transceiver module 13 and this, to receive optical module 132 corresponding one by one respectively for these two optical fiber 30a.The plurality of slot 50 is fixed on the edge of this circuit board 200, so that plug this external connected electronic device (not shown).
