It is basically identical that the construction of OPLC, installation, erection technique and traditional power circuit set up mounting means, but widely different aspect continuing, relate to fibre junction and photodetachment technology, the technology of continuing, High-Voltage Insulation are had to strict requirement, and OPLC connector box becomes the key technology that its practical application is urgently captured.For existing demand, be badly in need of design and can realize the connector box that OPLC is laid.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of photoelectric composite low-pressure cable-joint protector box, simple in structure, optical fiber splice box good airproof performance, and fiber cable joint protectiveness is good, realizes photodetachment, compact conformation, volume is little, is convenient to safeguard.
Be achieved through the following technical solutions above-mentioned purpose:
A kind of photoelectric composite low-pressure cable-joint protector box, comprise connector box lower floor, connector box upper strata, fibre junction dish and enter cable hole, described connector box lower floor is connected with connector box upper strata, what described connector box upper strata arranged a pair of symmetry enters cable hole, and described fibre junction dish is set at the middle part on described connector box upper strata.
Described connector box upper strata comprises box body and lid, and described box body and described lid form a built-in space.Fibre junction dish described in described built-in spatial placement, and described fibre junction dish and described connector box lower floor are bolted.Described enter on cable hole, to arrange separately in order to the fixing groove of briquetting.Between described lid and box body, arrange in order to seal the sealing ring in space between the two.
The beneficial effects of the utility model are: optical fiber composite low-voltage cable (OPLC) connector box that is applicable to 500kV electric pressure, whole box body is made by the engineering plastics that insulate, wherein securing member is made with nylon material, so that whole connector box has mechanical strength is high, and the feature of good insulation preformance; Structurally, its design comparison is simple, overall volume is less, take resource few, easy construction, fail safe is good, being designed to of its joint box body introduced from side, easily realizing the metal tube of clad optical fiber can introduce in connector box naturally along joint box body internal edge, and complete connection on connecting disk is convenient to repair and safeguard.The rubber blanket adding on joint box body makes its inner sealing better, and outside increases protective cover structure simultaneously, and butt joint box plays a very good protection.Compare with optical fiber composite low-voltage cable (OPLC) connector box in the market, there is reliable in mechanical performance, electric property is more excellent, sealing property is good, material is corrosion-resistant, the feature of excellent insulation performance.
