Fig. 6 and Fig. 7 illustrate upstream side joints of optical fibre cover body 42 and downstream joints of optical fibre cover body 43.In addition, two joints of optical fibre cover bodies 42,43 have same configuration, on one side upstream side joints of optical fibre cover body 42 of explanation here (below be called " joints of optical fibre cover body 42 ").As shown in Figure 6, joints of optical fibre cover body 42 is made of left and right sides sidewall 42a, 42b and top board 42c and forms " コ " i section, up-winding fiber connector 20a in the portion space within it.Like this; because under the state of closed joints of optical fibre cover body 42; open-ended the 10a (with reference to Fig. 1) that is separated out with pedestal 30 becomes essentially rectangular; so be easy to seamlessly to accommodate and connect the common insertion bar 12 (with reference to Fig. 1) that is used under the state that has connected up protection optical cable 11a etc., can connect up under the situation attractive in appearance considering.
Shown in Fig. 6 and Fig. 7 (A), two side 42a, 42b protrude in top board 42c in the central portion side (central cover body 41 sides) of fiber optic closure 10, supported hole 44 is set respectively on this outshot, and above-mentioned supported hole 44 is chimeric rotationally with the support protrusion 34a on the breakout box clamping part 32 that is arranged on said base 30.Thus, end (peristome 10a side) opened and closed before and after joints of optical fibre cover body 42 can make as rotation axis with the support protrusion 34a (34b) of central portion side end.In addition, owing to be provided with the space 42e that top board 42c is shorter than sidewall 42a, 42b, when opening and closing joints of optical fibre cover body 42, can prevent that itself and central cover body 41 from interfering.
In addition, otch 45 is set in the bottom of the switching side end (upstream-side-end among Fig. 6 is a left end) of two side 42a, 42b, its have with the rear and front end portion that is arranged on pedestal 30 on the chimeric shape of fastener 36a.Thus, make fastener 36a and otch 45 chimeric, can under the state of closed cover body 42, carry out locking by closed cover body 42.In addition, shown in Fig. 7 (C), near the inside switching side (right side among Fig. 7 (the C)) end of joints of optical fibre cover body 42 is provided with dividing plate 48, on the lower central position of dividing plate 48 otch 48a is set, and is used to make optical cable 11a to pass.
Thus, because downstream joints of optical fibre cover body 43 can open and close with respect to pedestal 30,, improve operability so make the user be easy to carry out the dismounting of joints of optical fibre 20b.In addition, because upstream side joints of optical fibre cover body 42 also can open and close with respect to pedestal 30 in the same manner, so upkeep operations such as inspection when being easy to carry out fault and reparations.
Shown in Fig. 7 (C), on the inside surface of the top board 42c of joints of optical fibre cover body 42, stiffening rib 42d is set with predetermined distance, even applying under the situation of external force, also can prevent the distortion of top board 42c, thereby protection is housed in inner joints of optical fibre 20a.In addition, as shown in Figure 8, dust cap 47 is set in the inboard of top board 42c.This dust cap 47 is one-body molded with the inside surface of mode free to rotate and top board 42c via thinner wall section 47a, in the situation that joints of optical fibre cover body 42 is opened upward with do not have under the situation of up-winding fiber connector 20a, it is positioned at the rectangular position of top board 42c with joints of optical fibre cover body 42.
Like this, if do not having up-winding fiber connector 20a, i.e. closed joints of optical fibre cover body 42 under the state of mounted connector not, then dust cap 47 covers the inside of fiber optic closure 10, covers the peristome of breakout box 21 at least, invades in the breakout box 21 so can prevent dust etc.
On the other hand, under the situation that contains joints of optical fibre 20a, if joints of optical fibre cover body 42 is closed downwards, then the front end of dust cap 47 and joints of optical fibre 20a butt make dust cap 47 rotate and accommodate to the direction of top board 42c.
In addition, also can make dust cap 47 and top board 42c separate moulding, carry out axle by pin and support and be rotatably mounted.In addition, also can be by volute spring etc. and with its closing direction pretension to joints of optical fibre cover body 42.
The central cover body 41 of expression in Fig. 9 and Figure 10.The breakout box 21 that central authorities' cover body 41 covers and protection is fixed by the breakout box clamping part 32 of pedestal 30.Central authorities' cover body 41 has: top board 41a, and it bends to mild convex, and section is circular-arc; And arm 41b, its two outer ledges from about the top board 41a extend downwards.On the inside surface of top board 41a, stiffening rib 41c (with reference to Figure 10 (C)) is set, prevents to be out of shape and protect and be housed in inner breakout box 21 with predetermined distance.In addition, the stop hole 46 of rectangular perforation is set in the central authorities of arm 41b, its be used for the breakout box clamping part 32 that is arranged on pedestal 30 on the chimeric and card of snap fit tabs 35 end.In addition, on the edge, upper surface rear and front end of top board 41a, cut out conical surface 48a and end difference 48b, when opening and closing joints of optical fibre cover body 42, prevent that the top board 42c of joints of optical fibre cover body 42 and the top board 41a of central cover body 41 from interfering, simultaneously under closure state, make between itself and the central cover body 41 very close to each other.Thus, prevent that dust etc. is from invading fiber optic closure 10 inside between central cover body 41 and the joints of optical fibre cover body 42.
Thus, by central cover body 41 is covered on the breakout box clamping part 32 of pedestal 30 from the top, arm 41b is pressed into downwards along the lateral surface of the recess 33a of clamping wall 33, the outside expansion that is tilted to that makes arm 41b one edge card end projection 35 descends on one side.Then, only projection 35 is chimeric with the stop hole 46 of arm 41b by making card, central cover body 41 can be fixed on the pedestal 30, prevents that breakout box 21 from coming off.
Like this, fiber optic closure 10 is made up of pedestal 30, upstream side joints of optical fibre cover body 42, central cover body 41, downstream joints of optical fibre cover body 43 these 4 parts.Because central cover body 41 can be dismantled when breakout box 21 from coming off independently preventing; in addition; upstream side joints of optical fibre cover body 42 and downstream joints of optical fibre cover body 43 are protected upstream side joints of optical fibre 20a and downstream joints of optical fibre 20b respectively; can independently open and close simultaneously, so application property and maintainability are fine.In addition, owing between each cover body 41,42,43 gap is not set, so can improve dust tightness.
