Embodiment
Fig. 1 is for trigger the skeleton view of covering (only being called covering hereinafter) 1 according to an embodiment of the invention, and Fig. 2 is the skeleton view of putting upside down of Fig. 1.Covering 1 has roughly tabular pushing portion 11, is connected to the straps 13 of pushing portion 11 pivotally and straps 13 is fixed to the stopper section 14 in the pushing portion 11 with separable mode through articulated section 12.Straps 13 is pre-formed and is C shape roughly.Straps 13 can be moved between the open mode shown in Fig. 1 or 2 (position) and the closure state (position) as shown in Figure 3 through articulated section 12 pivotally.In this embodiment; Stopper section 14 has leading section 131 places or near the conjugate foramen 132 of straps of being formed on 13 and is formed on the bonding part (the perhaps convexity among this embodiment) 111 in the pushing portion 11, makes protruding 111 these conjugate foramens 132 of joint when straps 13 is in the close position.Straps 13 is not limited to belt shape.Straps 13 can have different widths in its some part.Straps 13 can have circular cross section.
The parts that are used for straps 13 is connected to pushing portion 11 are not limited to the articulated section, as long as straps 13 can be with respect to 11 motions of pushing portion.For example, through making straps 13 elasticity or plastic yield, the leading section 131 of straps 13 can be for respect to pushing portion 11.Although pushing portion 11 forms with straps 13 is molded integratedly, two sections can form independent member.Yet aspect the maintenance and processing of covering, preferably two sections form.Covering can form through resin molded manufacturing, yet the manufacturing of covering is not limited to this.For example, covering can be formed by made.
Fig. 4 for covering 1 the skeleton view of the attached joints of optical fibre (only being called connector hereinafter) 2, Fig. 5 is the cross-sectional view along the V-V line of Fig. 4.Connector 2 is used for connecting optical fiber, and has mechanical splice 21 (Fig. 5), and this mechanical splice is constructed to fixing these two optical fiber (not shown) when the end of two fibers abuts against each other.As shown in Figure 3, the straps 13 of covering 1 forms accommodation section 15 ordinatedly with the pushing portion 11 that is in the close position, and this accommodation section 15 is around at least a portion that comprises top cover 212 of connector 2.
Figure 17 shows the instance of the structure that can be applied to connector 2 of the present invention.Connector 2 have mechanical splice 21, lasso 24 and be fixed on the lasso 24 than staple fibre 25.Mechanical splice 21 has core fibre fixed part 211, trunk structure 213 and top cover 212, and trunk structure has recess 2131, and this recess is constructed to hold core fibre fixed part 211, and top cover 212 can be with respect to recess 2131 motions.
Core fibre fixed part 211 has through articulated section 2,112 two side plates 2111 connected to one another and is positioned at the concave part 2113 that being constructed on its inside surface receives core fibre.Be inserted in advance the concave part 2113 than the leading section of staple fibre 24 a end, and another core fibre (not shown) inserts from another end of core fibre fixed part 211 from core fibre fixed part 211.Then, abut against each other with the end place of another core fibre than staple fibre 24, and optics connects each other at them.Shown in the cross-sectional view of Fig. 5, the xsect vertical with direction of insertion core fibre core fibre fixed part 211 is V-arrangement roughly.Be pushed downwards in the state before core fibre fixed part 211 at top cover 212, concave part 2113 has the space that is enough to receive optical fiber.When top cover 212 was pushed downwards to core fibre fixed part 211, two side plates 2111 were shifted into close to each other.During this period, the space of concave part 2113 narrows down, and the optical fiber in the concave part is fixed between two plates 2111.
Top cover 212 has base part 2121 and a pair of leg portions 2122, and this base part has the upper surface of pushing portion 11 promotions of lining cover piece 1, and this generally perpendicularly extends leg portions 2122 against each other and by base part 2121 (Fig. 5).Distance between the relative leg portions is less relatively near base part 2121, and relatively large away from base part 2121 places.Before the lid of ejection downwards 212; The end of each side plate 2111 all is received in the relatively large place of distance between the leg portions between the leg portions 2122; After the lid of ejection downwards 212, the end of each side plate 2111 all is received in the relative smaller part of distance between the leg portions between the leg portions 2122.Therefore, through top cover 212 is pushed in the connector 2, can fixedly be inserted into the optics core fibre in the groove 2113.
For example, lasso 24 is the substantial cylindrical member, and has center pit 241, can be inserted in this center pit 241 than staple fibre 25.Be fixed to the center pit 241 of lasso 24 through bonding agent etc. than staple fibre 25.An end 242 of lasso 24 be connected on the lasso of another connector (not shown) against the end, and polished or handle to form and the surface identical than the end surface of staple fibre 25.Than staple fibre 25 from lasso 24 with against the end 242 relative another ends 243 outstanding, and the outshot of staple fibre 25 is received by the groove 2113 of fiber fixed part 211.
Trunk structure 213 has recess 2132 at the one end thereof place, and lasso 24 is fixed to this recess 2132, and trunk structure 213 has through hole 2133 at its another place, end, and optical fiber is inserted in this through hole 2133.Lasso 24 arrives recess 2132 through for example adhesive.
Because the connector of this embodiment 2 is configured for the matrix connector that receives the convex connector; So connector 2 also has sleeve pipe 26 and adapter housing 27; This sleeve pipe 26 arranges coaxially that with lasso 24 adapter housing 27 covers an end of trunk structure 213 and has the recess that is configured to receive another connector.If desired, connector 2 can have and is configured to receive the housing (not shown) of trunk structure 213 and/or with the wind spring (not shown) of lasso 24 towards another connector bias voltage.In addition, connector can have the fixed mechanism (not shown), and this fixed mechanism is constructed to the introducing cable is fixed to connector.
As shown in Figure 2; The pushing portion 11 of covering 1 has top cover contact site 113 and connector clamping part 114 at inside surface (or when covering is attached to connector 2 in the face of the surface of connector 2) 112 places; Top cover contact site 113 is constructed to the top cover 212 of contact-connection assembly for electric 2 when covering 1 is attached to connector 2, and connector clamping part 114 is constructed to clamping connector.In an illustrated embodiment, top cover contact site 113 is protruding for the ridged that is formed on the inside surface 112, and clamping part 114 is to be formed on respect to one another a pair of bar member or the board member on the inside surface 112, thereby at the place, both sides of connector 2 connector 2 is clipped in the middle.Yet; Enough is; When covering 1 was attached to connector 2, top cover contact site 113 was along the pushing direction contact top cover 212 of top cover 212, and connector clamping part 114 is fixed to connector 2 with covering 1; So that when covering 1 is attached to connector 2, covering 1 can not carry out too big displacement with respect to connector 2.
As shown in Figure 5; When the straps 13 of covering 1 is in the close position; The convexity 111 of pushing portion 11 engages the conjugate foramen 132 of straps 13, the top cover 212 of the top cover contact site 113 contact mechanical splices 21 of pushing portion 11, and connector clamping part 114 is from the sandwich connector 2 of connector 2.In this, the inside surface 133 of the lower surface 22 of connector 2 (or with pushing portion 11 facing surfaces) and the straps 13 of covering 1 surface of connector 2 (or towards) is separated and is equal to or greater than zero distance ' ' d ' '.In order to prevent the direction that covering 1 changes along distance ' ' d ' ' with respect to connector 2 (vertical direction in Fig. 5) displacement; Shown in Figure 6 like what see along the direction of arrow VI; The clamping part 114 of covering 1 is made up of a plurality of bar member 114a, 114b and 114c; And go up formation kick 115 at a bar member (being 114b in the drawings), this projection is extended towards adjacent bar member (being 114c in the drawings).On the other hand, connector 2 has protruding 23 (Fig. 7) of ridged, and the width that this ridge projections 23 has is substantially equal to the distance between bar member 114b and the 114c.Therefore, can prevent the displacement of covering 1, reason is the upper end 231 of the ridged protruding 23 that projection 115 can joining connector 2.Projection 115 can be outstanding towards connector 2, rather than outstanding towards adjacent bar member.In this case, the side surface of connector 2 surface of bar member (or towards) can have can copulational protuberance 115 recess or projection.In addition, fall from connector 2, can on connector clamping part 114, form extra projection in order to prevent covering 1 effectively.
Fig. 7 and 8 shows the operation that is used for covering 1 is attached to connector 2.At first, as shown in Figure 7, covering 1 motion makes the pushing portion 11 of covering 1 be positioned at top cover 212 tops of connector 2.Next, as shown in Figure 8, covering 1 engages with connector 2, makes bar member 114a, 114b and the 114c of covering 1 that connector 2 is clipped in the middle.In this, the position between covering 1 and the connector 2 relation is confirmed as and makes the top cover contact site 113 (Fig. 2) of covering 1 separate with the top cover 212 of connector slightly or contact (not pushing away) top cover 212 slightly downwards.Such position relation can realize like this; Promptly through confirming the position of projection 115; Make when projection 115 contacts the upper end 231 of ridgeds protruding 23; Contact site 113 contact top covers 212 are perhaps separated with top cover 212 slightly, and through making covering 1 towards connector 2 motions, up to the upper end 231 of projection 115 contact ridges 23.At last, as shown in Figure 4, straps 13 engages with pushing portion 11, thereby covering 1 is fixed to connector 2.
When covering 1 was pushed in the connector 2, bar member 114b, 114c were positioned at respect to ridged protruding 23 on the side of connector 2 (Fig. 7), and the upper surface of the surface in contact of the contact site 113 of covering 1 and top cover 212 can keep the state of almost parallel thus.Therefore, during the attended operation of optics core fibre, top cover 212 can with the situation of the body almost parallel of connector 2 under be pushed downwards.Through the lid of ejection downwards 212 under the situation parallel with connector, core fibre fixed part 211 can not tilt, and can avoid the damage of core fibre in the fiber fixed part and/or high connection loss.Can in following situation, ejection downwards cover 212, wherein top cover 212 is parallel with the body of connector 2, the bar member that on the side of connector 2, forms groove (this groove extends to lower surface from the upper surface of connector) and pass through joint covering member 1.Although protruding 23 upper surfaces from connector 2 of ridged extend to lower surface continuously in this embodiment, this convexity can be made up of a plurality of discontinuous parts.
Shown in Fig. 5 or 9, bar member 114a, 114b and 114c form the distance that makes between the relative bar member and narrow down gradually towards its leading section (downward in Fig. 5).Therefore, connector 2 can be by the clamping lightly of bar member, makes that connector 2 can not be because of himself weight and drop, though thus when the straps 13 of covering 1 is shown in an open position connector 2 can not drop from covering 1 yet.
Bar member 114 can form (for example, on the inside surface of straps 13) with straps 13, perhaps with among this embodiment equally can form (for example, being formed in the pushing portion 11) independently with straps 13.Through forming bar member 114 independently, even connector 2 also must be by the clamping of bar member when straps 13 is shown in an open position with straps 13.
The straps 13 of covering 1 is not a full flexible, and when being in the close position, is used as the body of rigidity substantially.Perhaps; Straps 13 can have flexibility to a certain degree; But have rigidity, make the operator has the situation of connector of covering with fingers under (particularly, operator's finger is with respect to the band-like portions 134 relative with pushing portion 11 of connector 2 contact pushing portions 11 and straps 13); If the operator applies unintentionally the pressure of band-like portions 134 towards pushing portion 11 bias voltages, the operator can not push away the top cover 212 of mechanical splice 21 downwards so.In other words; The straps 13 that is in the close position has rigidity to a certain degree; Thus, imposed under the pressure of connector by the operator usually, the distance that the inside surface 133 of straps 13 can be shifted towards the lower surface 22 of connector 2 can be greater than the distance ' ' d ' ' among Fig. 5.Therefore, except can not receiving external force etc., the operator's lid of ejection downwards 212 (or closed mechanical splices 21) unintentionally also when transporting connector, have been prevented through covering 1 protection connector 2.Distance ' ' d ' ' is confirmed as and makes connector 2 can not drop from the covering 1 that forms accommodation section 15 (that is, connector 2 can not carry out too big displacement along the axial direction of core fibre with respect to covering 1).
Fig. 9 is the cross-sectional view of the connector with covering 12 seen along the direction identical with Fig. 5, and shows the state that the straps 13 of covering 1 is shown in an open position.When the core fibre (not shown) was connected in the connector 2, as shown in Figure 9, the convexity 111 of pushing portion 11 was thrown off with the conjugate foramen of straps 13 132, straps 13 rotations then.In this embodiment, straps 13 is around the axis rotation parallel with the axis direction (that is the longitudinal direction of connector) of core fibre.Then, the operator is at lower surface 22 place's clamping connectors 2 of outside surface 116 of pushing portion 11 (or with towards connector 2 inside surface facing surfaces) and connector 2, and exert pressure so that pushing portion 11 towards connector 2 motions.Therefore, the top cover contact site 113 of pushing portion 11 pushes away the top cover 212 of mechanical splice 21 downwards, and core fibre fixed part 211 closures, accomplishes the attended operation of core fibre thus.Preferably, the outside surface 116 of pushing portion 11 forms recessed portion, with handled easily person's operation.
As stated, in having the connector of covering of the present invention, top cover can not be pushed downwards, only if the straps of covering moves to open position.As shown in Figure 9, the leading section 131 of straps 13 can have tongue 135, and this tongue 135 is extended along the direction of different with the bearing of trend of leading section 131 (being vertical with this bearing of trend in this embodiment).
Figure 10 show covering 1 into the modification of covering 1 '.The pushing portion 11 of covering 1 ' have and covering 1 and articulated section 12 similar pushing portions 11 ' and articulated section 12 '; And have straps 13 ', this straps 13 ' be connected to pivotally articulated section 12 ' and have with the distance piece part 139 of straps 13 ' form '.As similarly shown in Figure 11 with Fig. 5, distance piece part 139 ' be constructed to make when straps 13 ' distance piece part 139 when moving to make-position ' the side of leading section 1391 ' be inserted in top cover 212 on connector 2 upper surface 28 and pushing portion 11 ' lower surface 112 ' between.The motion of straps 13 ' between the open and close position for ease, can reduce distance piece part 139 ' base part 1392 ' thickness.Therefore; When straps 13 ' around the articulated section 12 ' when make-position rotates to open position; Distance piece part 139 ' can be in base part 1392 ' locate bending, thus distance piece part 139 ' can be easily from the top cover of connector and covering 1 ' pushing portion 11 ' between extract out.Otherwise, distance piece part 139 ' can be from straps 13 ' extension, simultaneously straps 13 ' base part 1392 ' curvature and straps 13 ' rotatablely move corresponding, distance piece part 139 ' can also easily extract out thus.
Can have discontinuous distance piece member 3 according to connector of the present invention, shown in figure 12, and do not have aforesaid distance piece part 139 '.Distance piece member 3 has by the retained part 31 of operator's clamping and the insertion portion 32 that forms with retained part 31.With above-mentioned distance piece part 139 ' leading section 1391 ' similar, when straps 13 moved to make-position, insertion portion 32 can be inserted between the lower surface 112 of upper surface 28 and pushing portion 11 of the connector 2 on the side of top cover 212.The thickness of distance piece member 3 be substantially equal to or greater than top cover 212 from the outstanding length of the upper surface of connector 28.Therefore, when pushing portion 11 is pushed to connector 2 and distance piece member 3 when being inserted into, prevented that top cover 212 is pushed downwards the body to connector 2.
Shown in figure 13, the insertion portion 32 of distance piece member 3 can be arranged on the both sides of top cover 212, or is arranged on the side of top cover 212.Particularly, when connector can be limited the member (such as a plurality of bar members) of this connector around the rotation of its axial direction and kept, even when the distance piece member only is arranged on the side of top cover, can prevent effectively that also top cover is pushed downwards.
Otherwise distance piece member 3 can be constructed to through moving with respect to covering with straps 13 different portions.Particularly, covering and distance piece member can be through such as being connected to each other with the turn up the soil connection part of the wire rod arranged of band-like portions.When using with the separated distance piece of covering member 3, covering can not have straps, only if covering is difficult for falling from connector.In this case, each in distance piece member, connector and the covering can have connected structure, is thus connected device and can be connected via the distance piece member with covering.
When aforesaid distance piece part 139 ' or distance piece member 3 during as distance piece, the straps of covering can not have certain rigidity, that is, can be flexible.
Figure 14 shows the covering of revising into the another kind of covering 11 ".Covering 1 " has pushing portion 11, articulated section 12 and straps 13 similar pushing portions 11 with covering 1 ", articulated section 12 " with straps 13 ", and the outside surface 136 that straps 13 " has in straps 13 " " is gone up the aciculiform or the rod projection 137 that form ".Because projection 137 ", if the operator will be in straps 13 " closed mechanical splice under the situation about being in the close position, projection 137 so " maybe stimulation applications person finger, can avoid operator's faulty operation thus.Recess or step can be used for replacing projection, as long as the finger that it can stimulation applications person.
