Abstract

The utility model discloses optical cable, cable splice closure, including taking air door box body, end cap and sealing strip, the box body is formed through connection structure combination by the middle two parts that open and shut, and there is cable inlet hole at the box body both ends, and cable inlet hole is overall structure with the box body, end cap and cable inlet hole threaded connection, and the sealing strip is located cable inlet hole and end cap cooperation department. The structure is simple, the universality is good, the connection protection can be performed on the optical cable with large core number, the large-pair cable and the medium-sized comprehensive cable, the direct-through type and branch type connection boxes can be assembled through different combinations, the air tightness is good, the device is suitable for overhead, buried and pipeline use, and the connection protection of the large-pair cable in a manhole is particularly convenient.

Description

Novel optical cable, cable splice box

The utility model relates to a kind of optical cable, cable splice device, particularly relates to a kind of novel optical cable, cable splice box.

Along with development of Communication Technique, the long haul communication transmission optical fiber that adopt more, local telephone communications etc. still use and develop all-plastic cable, the involution mode of resolving joint is crucial, must satisfy the energy moistureproof and waterproof, certain physical construction is arranged, can reopen coincidence, use repeatedly, and arranged long serviceable life.The involution mode of optical cable and cable splice is a lot of at present, disclose a kind of all-plastic cable as Chinese patent CN95229783.3 and connect the cable box, it comprises the body that is provided with valve, with body two ends threaded engagement and the into end cap in cable hole is arranged, and with the gland that advances cable hole threaded engagement.This splice tray adopts unit construction form, detachable, assembling, uses repeatedly, but has four to connect seam on its splice tray, and its faying face is not minimum.Therefore, to the sealing of four seams, in operation, have relatively high expectations relatively.

The purpose of this utility model is to provide a kind of faying face minimum, and box body is novel optical cable, the cable splice box of middle folding.

The novel optical cable of the utility model, cable splice box are achieved in that it comprises box body, end cap and the sealing strip of being with valve.Box body is combined by syndeton by two parts of middle folding, and there is into cable hole at the box body two ends, and advancing cable hole and box body is one-piece construction, and end cap is threaded with entering the cable hole, and sealing strip is positioned at into cable hole and end cap cooperation place.For guaranteeing end cap and advancing being sealed and matched between the cable hole, end cap is good with interior Crossed Circle structure, in it ring with advance cable hole inwall and cooperate, outer shroud with advance cable hole outer wall thread and cooperate, make in it ring compression seal bar by screwing end cap, to guarantee end cap and to advance impermeability between the cable hole.The cable hole of advancing on the box body is 1～3 hole, is convenient to box body is combined into through type (one-in-and-one-out) splice tray and branch's formula (one-in-and-two-out or advances three and goes out) splice tray.Bindiny mechanism in the middle of the box body can be the abutment ring that is connected with box body two combination end-face helicals, and there is O-ring seal abutment ring and box body junction, generally are used for cylindrical box body; Bindiny mechanism in the middle of the box body also can be, box body link place has with it becomes holistic flange arrangement, and connecting on the end face has boss and the groove that cooperatively interacts respectively, and there is O-ring seal at boss and groove fit place, generally are used for square or the polygon box body.

When the novel optical cable of the utility model, the use of cable splice box, end with end cap, box body is inserted in cable to be continued respectively in opposite directions successively, and abutment ring is enclosed within on the link on box body one side, after the relevant specification that continues by cable continues and finishes then, the distance of adjusting between ply-yarn drill is also fastening, O-ring seal is put into the cooperation place, again the two ends box body is moved to the protective position that continues, screw abutment ring, enter the cable hole at the box body two ends at last and insert sealing strip, screw end cap, and utilize the valve inflation to check its sealing; Perhaps successively an end of end cap, box body is inserted in cable to be continued respectively in opposite directions; after the relevant specification that continues by cable continues and finishes then; the distance of adjusting between ply-yarn drill is also fastening; O-ring seal is put into the groove of box body abutting end, again the two ends box body is moved to the protective position that continues, boss is embedded in the groove; and with the flange on the bolt locking box body; enter the cable hole at the box body two ends at last and insert sealing strip, screw end cap, and utilize the valve inflation to check its sealing.During maintenance, the end cap of outwarding winding earlier takes out sealing strip, the box body of outwarding winding again, and be pushed into two ends, the left and right sides, and exposing the part that continues, can keep in repair, the maintenance back resets by said procedure.

The advantage of the novel optical cable of the utility model, cable splice box is simple in structure; versatility is good; count the protection that all can continue of optical cable, big logarithm cable and medium-sized comprehensive cable for big core, and can pass through various combination, be assembled into through type splice tray and branch's formula splice tray; impermeability is good; can utilize valve to inflate inspection immediately, reopen and overlap conveniently the physical strength height; be applicable to that built on stilts, buried, pipeline uses, convenient especially the continue protection of big logarithm cable in manhole.

Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
