Embodiment
To be described in further detail embodiment of the present invention below in conjunction with accompanying drawing.
Refer to Fig. 1-4, it comprises a kind of joints of optical fibre 100: main part 10, collimation portion 20, optical fiber 30 and lid 40.
This main part 10 is L-type, it comprise interface 11, with the opposing installed surface 12 of this interface 11 and with the perpendicular upper surface 13 of this installed surface 12.
This interface 11 comprises the first installing zone 111, and this installed surface 12 comprises the second installing zone 121, and this first installing zone 111 is corresponding with the position of this second installing zone 121, and in the present embodiment, this first installing zone 111 is all rectangular with this second installing zone 121.This collimation portion 20 is arranged on this second installing zone 121.
This upper surface 13 offers accepting groove 131, and the cross section of this accepting groove 131 is semicircle shape.This accepting groove 131 extend axially vertical this installed surface 12 of direction, this accepting groove 131 is aimed at this collimation portion 20, this optical fiber 30 be positioned at this accepting groove 131 and with this collimation portion 20 separately, particularly, can this optical fiber 30 be fixed in this accepting groove 131 by glue.
This interface 11 is arranged at intervals with two keepers 110; This keeper 110 is slot or projection.Relative position when this keeper 110 is used for controlling with other optically-coupled modular connector.In the present embodiment, the edge of this keeper 110 contiguous these the first installing zones 111, these two keeper 110Liang Ge centers are at the orthogonal projection of this interface 11 and this first installing zone 111 center point-blank.In the present embodiment, the cross section of slot or projection is all rounded.This main part 10, collimation portion 20 and this keeper 110 structure that is formed in one, wherein, in present embodiment, this collimation portion 20 is convex lens.
In present embodiment, the structure that this collimation portion 20 and the main part 10 that is provided with this accepting groove 131 are formed in one, thus while having avoided collimation portion 20 to dock with the main part 10 of placement optical fiber 30, be not easy to occur contraposition deviation and the light signal energy loss that causes; And this keeper 110 is arranged on opposing two sides with this collimation portion 20, has avoided this collimation portion 20 to be broken or scratch, has improved the transfer efficiency of light signal.
This lid 40 is roughly rectangular structure, and it comprises first surface 41, opposing second surface 42 parallel with this first surface 41, on this second surface 42, offers holding tank 43; The cross section of this holding tank 43 is semicircle shape.This holding tank 43 and the common storage tank 45 that forms this optical fiber 30 of clamping of this accepting groove 131.Thereby this second surface 42 contacts this lid 40 is positioned on this main part 10 with this upper surface 13.
In the present embodiment, can adopt glue (not shown) that this lid 40 is fixing with this main part 10, in other embodiments, groove (projection) can be set on the second surface of this lid 40 42, at this upper surface 13, projection (groove) is set, this groove (projection) is matched with this projection (groove), thereby fix this lid 40 and this main part 10.
By lid 40 being covered to the upper surface of main part 10, thereby the optical fiber head of optical fiber 30 and this collimation portion 20 are covered, avoided like this dust to trickle down the optical fiber head surface with this optical fiber 30 in this collimation portion 20, promote the transfer efficiency of light signal.
Refer to Fig. 5, a kind of joints of optical fibre 200 that second embodiment of the invention provides, the joints of optical fibre 100 of these joints of optical fibre 200 and the first embodiment are basic identical, its difference is: this main part 10 also comprises the projection 14 of a rectangle, the structure that this projection 14 and this main part 10 are formed in one.This projection 14 is arranged on this interface 11 and covers this first installing zone 111, and this keeper 110 is arranged on this projection 14.This projection 14 comprises the non-optical zones 142 of Optical Region 141 and 141 both sides, Optical Region.Thereby this Optical Region 141 is with this, the corresponding light signal that can make passes through with these the first installing zone 111 positions, this keeper 110 is positioned at this non-optical zones 142, particularly, make the line of the orthogonal projection of two this keeper 110Liang Ge centers on this projection 14 through this projection 14 center, the orthogonal projection of this collimation Bu center on this interface 11 also drops on this line.Present embodiment is by this interface 11, a projection 14 being set, and this keeper 110 is arranged on projection 14, utilizes this projection 14 to observe collimation portion, optical fiber whether be positioned at the position of appointment with keeper 110 and without contraposition deviation.
