Embodiment
Referring to Fig. 1～Figure 35, the utility model elastomeric seal member can be divided into two big classes:
One, be used for the hat type cable splice closure the elastomeric seal member (referring to Fig. 1～Fig. 8):
This elastomeric seal member has two kinds of purposes, the one, the elastomeric seal member that is used for the hat type cable splice closure is loaded on the large sealing packing ring between hat type cable splice closure housing and anchor ear, the nut, its basic structure is the sealing strip 1 of annular, it is characterized in that being respectively equipped with detent 12 or positioning convex 11 or outer peripheral face in the one or both sides of described sealing strip 1 is the conical surface.Embodiment as depicted in figs. 1 and 2, the front of annulus sealing strip 1 (upside of Fig. 2) is provided with positioning convex 11; Fig. 3 and embodiment shown in Figure 4 are that the reverse side (following) of round rectangle sealing strip 1 is provided with detent 12; (be provided with positioning convex 11, reverse side is provided with detent 12 for the front of annulus sealing strip 1 for Fig. 5 and Fig. 6.Sealing strip 1 can also be the elliptical shape or the Any shape of coincideing with hat type cable splice closure housing.Described positioning convex 11 and detent 12 respectively and the male and fomale(M﹠F) of the faying face between hat type cable splice closure housing and anchor ear, the nut match.In order to guaranteeing that large sealing packing ring is difficult for displacement, the pressure that in the time of also can alleviating sealing hat type cable splice closure simultaneously housing and fixed structure piece is caused has guaranteed that sealing property remains unchanged for a long period of time.
Second kind of purposes of the elastomeric seal member of hat type cable splice closure is to be loaded on the nut of the hat type cable splice closure that adopts the turnover of cap rotating-type sealing optical cable and the small sealing ring (referring to Fig. 7 and Fig. 8) between the optical cable turnover pipe, be circle, its internal diameter is identical with corresponding optical cable turnover bore, and diameter is identical with the diameter of corresponding optical cable turnover pipe.The cross section of small sealing ring can be trapezoid (as shown in Figure 7), also one side has the gradient (the inclined ladder shape that matches with the corresponding optical cable turnover pipe mouth of pipe, as shown in Figure 8), after optical cable penetrates, rotation along with nut, small sealing ring can be held optical cable automatically tightly, guarantees the reliability of optical cable turnover and optical cable sealing.When optic cable diameter during less than optical cable turnover bore, should pass in and out the position at optical cable and suitably increase the external diameter of this section optical cable with sealant tape, guarantee that the sealing of cable splice closure is reliable.
The elastomeric seal member that is used for the hat type cable splice closure, its large sealing packing ring makes large sealing packing ring compress sealing hat type cable splice closure housing buckling surface by the lid and the base of anchor ear lock sealing hat type cable splice closure.The rotation of small sealing ring by optical cable turnover pipe nut fixedly optical cable compresses and seals the optical cable manhole appendix.Thereby guarantee that the hat type cable splice closure has excellent sealing performance for a long time.
Two, the elastomeric seal member that is used for the Hafu type cable splice closure is (referring to Fig. 9～Figure 35): between the elastomeric seal member that is used for Hafu type (horizontal) cable splice closure is loaded at the bottom of the lid of Hafu type cable splice closure housing and the box, its basic structure is (referring to Figure 15～Figure 17) or two ends (referring to Fig. 9～Figure 11 at described sealing strip 1 (it is shaped as round rectangle or fillet is a trapezoidal) end, Figure 27～Figure 29, Figure 33～Figure 35), be provided with and connect to one with described sealing strip 1, be used to pass sealing optical fiber cables seat 2, sealing strip 1 and sealing socket 2 constitute the seal of a disjunctor.On sealing seat 2, be provided with at least one semi-circular recesses 21; On sealing seat 2, be provided with a gland bonnet, on described sealing socket 2 and gland bonnet 3, be provided with corresponding mounting hole 22 and 32 with semi-circular recesses 31 corresponding with semi-circular recesses 21.In the semi-circular recesses 21 of sealing socket 2 and gland bonnet 3 and 31 formation circular ports, be provided with identical seal plug 4.
The seal groove that matches with above-mentioned elastomeric seal member is arranged on the lid of Hafu type cable splice closure housing and the buckling surface at the bottom of the box, and this elastomeric seal member just is positioned in the seal groove.
Described sealing strip 1 can be similar to rectangle with the shape of the disjunctor seal that sealing socket 2 constitutes, and also can be similar to trapezoidal (as figure Figure 33～shown in Figure 35).Sealing socket 2 is basic identical with the shape and the structure of gland bonnet 3.All there is the semi-circular recesses 21 and 31 of several or a plurality of different inner diameters that are arranged side by side gland bonnet 3 and sealing socket 2 inboards.2 pairs of gland bonnet 3 and sealing sockets are buckled together the circular optical cable manhole appendix that can form several or a plurality of different inner diameters.Optical cable can be put into the optical cable manhole appendix like a cork during construction, has saved the cutting sealing part and optical cable is penetrated time of optical cable manhole appendix, makes construction more convenient.Gland bonnet 3 and sealing socket 2 are equipped with mounting hole 32 and 22, are used to pass gib screw.Buckling surface at gland bonnet 3 and sealing socket 2 has recessed 34,24 and the projection 33,23 that matches, and is guaranteeing also to play the effect that makes the two stationkeeping be difficult for displacement when the two closely fastens.The detent 12 and the positioning convex 11 that match at the seal groove that can have on gland bonnet 3, sealing socket 2 and the sealing strip 1 with buckling surface at the bottom of Hafu type cable splice closure lid and the box, be difficult for displacement in order to guarantee that this elastomeric seal member can be stuck in securely in seal groove, the pressure that in the time of also can alleviating simultaneously sealing Hafu type cable splice closure housing and fixed structure piece is caused has guaranteed that sealing property remains unchanged for a long period of time.
The Elastic Cylindrical body plastic seal plug 4 of in gland bonnet 3 and 2 pairs of sealing sockets are buckled together the optical cable manhole appendix of formation, all being furnished with respective diameters.Sealing plug 4 can be combined closely with the optical cable manhole appendix.During optical cable turnover Hafu type cable splice closure, only need open cable splice closure, take off seal plug 4 with the corresponding optical cable manhole appendix of optic cable diameter, again optical cable is placed on the optical cable manhole appendix and gets final product by cable splice closure is fixing, when optic cable diameter during less than optical cable manhole appendix internal diameter, should pass in and out the position at optical cable and suitably increase the external diameter of this section optical cable, make its external diameter identical with optical cable manhole appendix internal diameter with sealant tape.Other optical cable manhole appendixs then by seal plug 4 sealings, guarantee that the sealing of cable splice closure is reliable, also can be used as the reserve cable manhole appendix simultaneously, convenient dilatation increment from now on.This elastomeric seal member can be installed many optical cables simultaneously according to the capacity of Hafu type cable splice closure.
This elastomeric seal member passes on Hafu type cable splice closure housing, gland bonnet and the sealing socket corresponding mounting hole by gib screw and is fixed, utilize fastening buckling surface and the optical cable manhole appendix that compresses sealing cable splice closure housing at the bottom of Hafu type cable splice closure lid and the box, thereby guarantee that the Hafu type cable splice closure has excellent sealing performance for a long time.
Adopt the construction of the utility model elastomeric seal member to save time fast.Can be the time of installation saving more than 50%, is that maintenance and dilatation increment save for 70% set-up time.
