Abstract
The utility model discloses a single core cable straight-through type intermediate connector which is used for connecting two mineral insulated cables. A sealing element, which is used for connecting a bare core wire conductor and a copper sheath, is arranged at the starting position of the bare core wire conductor. The single core cable straight-through type intermediate connector comprises an intermediate connecting tube, a straight-through type intermediate coupling sleeve, a porcelain sleeve, stuffing box bodies, stuffing nuts, and compression rings, wherein the stuffing box bodies are connected on two ends of the intermediate connecting tube and the straight-through type intermediate coupling sleeve by screw threads, the stuffing nut is connected on an outer end of the stuffing box body by a screw thread, and the compression ring is installed on the outer end of the stuffing box body in a press-in manner via the stuffing nut. The stuffing box body is provided with a sealing element containing hole used for containing the sealing element. The sealing elements are contained in the sealing element containing holes of the stuffing box bodies after the two mineral insulated cables penetrate through the stuffing box bodies. According to the utility model, double sealing is formed by adopting sealing tanks, a sealing material and the compression rings so as to prevent the cable from being damped. The connector can live for 3 hours in flame with a temperature of 950 DEG C together with the mineral insulated cables.
Description
Technical field
The utility model relates to the mineral insulated cable field of connectors, particularly a kind of single-core cable through type intermediate connector.
Background technology
Mineral insulated cable is called for short the MI cable, and domestic custom is called copper core sheath magnesium oxide insulating cable or fireproof cable.Mineral insulated cable is to adopt the metallic copper of high conductivity to do conductor, and inorganic matter magnesia is done insulation, and copper pipe is made a kind of cable of sheath.
The single-core cable intermediate connector basic structure that each MI cable manufacturer is equipped with all relates to according to " mineral insulated cable lays atlas " ZJ series through type intermediate connector in (99D163); Major part all is to adopt moisture preventive measure and the insulating means of heat-shrinkable T bush as cable at present; Referring to shown in Figure 1; One end of two sections insulated cables 1 ' exposes one section cored wire conductor 6 ' separately; The said cored wire conductor that exposes separately 6 ' two ends link together through crimping sleeve 5 ', and this crimping sleeve 5 ' is coated with heat-shrinkable T bush 4 ', and heat-shrinkable T bush 4 ' is coated on cored wire conductor, crimping sleeve and the cable copper sheath (crust); Heat-shrinkable T bush has been sealed the space between copper sheath and the conductor, prevents moisture intrusion insulating barrier.Big envelope body 3 ' is enclosed within outside the heat-shrinkable T bush 4 '; The big envelope body passes through on big envelope nut 2 ' the fixed insulation cable 1 ' for 3 ' two sections; Page or leaf has fraction to adopt to hold in the hermetically sealed can fluid sealant and Bakelite Cover as seal means, adopts the insulation of heat-shrinkable T bush or porcelain bushing simultaneously.
But under fire or high temperature; Though cable can tolerate 1000 degrees centigrade high temperature; But because heat-shrinkable T bush that intermediate connector uses or fluid sealant and Bakelite Cover carburizing temperature are about between 300-500 ℃, can cause sheath and core short circuit, cause the whole piece line powering to stop.
