Abstract
The invention relates to a joint for a mineral insulation heating cable, comprises a mineral insulation heating cable and is characterized by also comprising a mineral insulation conductive cable, a common insulated cable, a cold and hot switching member and a cable switching member, wherein one end of the mineral insulation heating cable is welded in the cold and hot switching member, one end of the mineral insulation conductive cable is also welded in the cold and hot switching member, the heating core of the mineral insulation heating cable and the conductive core of the mineral insulation conductive cable are welded, the cold and hot switching member is filled with insulating powder, the other end of the mineral insulation conductive cable is welded in the cable switching member, one end of the common insulated cable is also welded in the cable switching member, the conductive core of the mineral insulation conductive cable and the cable core of the common insulated cable are welded, and the cable switching member is filled with sealant. The invention adopts two part connection mode, thus being capable of using higher temperature without worrying about problems of sealant.
Description
Technical field
The present invention relates to a kind of mineral insulation heating cable, particularly relate to a kind of joint of mineral insulation heating cable, is to the improvement of existing mineral insulation heating cable structure, belongs to the mineral insulation heating cable manufacturing technology.
Background technology
At present, the mineral insulation heating cable of domestic production has a lot, for example, publication number be the Chinese utility model patent of CN2362253 provided that " a kind of mineral insulation heating cable " and the applicant provide patent application formerly--application number is 2007101589371 application for a patent for invention " high temperature mineral insulation heating cable ", though above mineral insulation heating cable has the intensity height, non-oxidizability and corrosion resistance are good, can in high temperature (600~1100 ℃) oxidizing atmosphere and under the exhaust gas corrosion condition, bear the characteristics of big stress and long service life, but owing to it very easily absorbs airborne steam the moisture absorption takes place, insulation is descended can not be used, existing solution is to solve by the glue envelope, but because serviceability temperature is higher, the glue envelope is prone to problem.
Summary of the invention
Purpose of the present invention just is to overcome the prior art above shortcomings, improve by research, provide a kind of joint of novel mineral insulation heating cable, this novel joint has adopted two parts to connect mode: the first step, with the common insulated cable switching of mineral insulation heating cable and lead-in wire, the end that will generate heat separates with lead end; Second step, adopt encapsulating method that common insulated cable is drawn, thereby can use higher temperature, satisfy instructions for use, and worry that no longer the glue envelope goes wrong.
The technical solution that the present invention provides is: the joint of this mineral insulation heating cable, include mineral insulation heating cable, be characterized in also including the mineral insulation conductive cable, common insulated cable, cold and hot bridgeware and cable bridgeware, one end of wherein said mineral insulation heating cable is welded in the cold and hot bridgeware, one end of described mineral insulation conductive cable also is welded in the cold and hot bridgeware, the heating core of mineral insulation heating cable welds mutually with the conductor wire core of mineral insulation conductive cable, dosed insulating powder in the cold and hot bridgeware, the other end of described mineral insulation conductive cable is welded in the cable bridgeware, one end of common insulated cable also is welded in the cable bridgeware, the conductor wire core of mineral insulation conductive cable welds mutually with the cable core of common insulated cable, has dosed fluid sealant in the cable bridgeware.
The structure division that does not elaborate in the present invention (as insulating powder, fluid sealant) is same as the prior art, particularly the patent application formerly that provides with the applicant--and application number is that 2007101589371 application for a patent for invention " high temperature mineral insulation heating cable " is identical.
Compared with prior art, beneficial effect of the present invention is: adopted two parts to connect mode: the first step, and with the mineral insulation conductive cable switching of mineral insulation heating cable and lead-in wire, the end that will generate heat separates with lead end; Second step, adopt encapsulating method that common insulated cable is drawn, thereby can use higher temperature, satisfy instructions for use, and worry that no longer the glue envelope goes wrong.
Description of drawings
Accompanying drawing is the structural representation of the embodiment that provides of the present invention.
Embodiment
Below in conjunction with embodiment concrete technical scheme of the present invention is described further:
As shown in the figure, the joint of this mineral insulation heating cable, include mineral insulation heating cable 1, mineral insulation conductive cable 6, common insulated cable 10, cold and hot bridgeware 2 and cable bridgeware 7, wherein the welding 11 of an end of mineral insulation heating cable 1 is in cold and hot bridgeware 2, one end of described mineral insulation conductive cable 6 also welds 12 in cold and hot bridgeware 2, the heating core 3 of mineral insulation heating cable 1 welds 13 mutually with the conductor wire core 4 of mineral insulation conductive cable 6, dosed insulating powder 5 in the cold and hot bridgeware 2, the other end welding 14 of described mineral insulation conductive cable 6 is in cable bridgeware 7, one end of common insulated cable 10 also is welded in the cable bridgeware 7, the conductor wire core 4 of mineral insulation conductive cable 6 welds 15 mutually with the cable core 9 of common insulated cable 10, has dosed fluid sealant 8 in the cable bridgeware 7.
