Abstract
The utility model relates to a kind of New Mineral insulation heating cable connector, by insulated conductor cable (1), insulation heating cable (2), jointing (3), magnesia powder (4) and joint end cap (5) form, the left end of its insulated conductor cable (1) is embedded in jointing (3), the right-hand member of insulation heating cable (2) is embedded in jointing (3), it is embedded between the left end of the insulated conductor cable (1) in jointing (3) and the right-hand member of insulation heating cable (2) and has filled magnesia powder (4), two ends, jointing (3) outside all arrange a joint end cap (5), the beneficial effects of the utility model are: high temperature resistant, the applicable place that needs laser heating, expanded the scope of application, it uses coefficient of safety high, long service life, structural design is simple, easy for installation.
Description
technical field:
The utility model relates to electrical heating elements technical field, relates in particular to a kind of mineral insulation heating cable connected mode.
background technology:
In prior art, mineral insulation heating cable joint has two kinds, and the first is with oxygen welding, to weld heating wire in junction, is packaged in the sleeve pipe of metal by high-temp glue, metal sleeve and cable cover(ing) adopt stainless steel material to make, and are generally only applicable to serviceability temperature in the environment below 150 ℃; Another kind is to adopt magnesia powder to fill, and then rear welding is tightened with screw thread in two ends, and joint precipitates nature by magnesium oxide powder and falls tightly by manually beaing when filling magnesia powder, then screw thread place is welded with argon arc welding; This kind of joint due to magnesia powder fill solid not, inner air is more, very easily occurs the phenomenon of air-blowing when welding, inner powder can spray simultaneously, causes the qualification rate of joint greatly to reduce, and has a strong impact on the quality of product.
utility model content:
The purpose of this utility model is to propose a kind of New Mineral insulation heating cable connector, and insulating powder is filled accurate, and heating property is good, good sealing effect, electrical insulation properties is good, easy to operate, and qualification rate is high, use coefficient of safety is high, and long service life is applied widely.
Main feature of the present utility model is: insulated conductor cable, insulation heating cable, jointing, magnesia powder and joint end cap, consist of, the left end of its insulated conductor cable is embedded in jointing, the right-hand member of insulation heating cable is embedded in jointing, it is embedded between the left end of the insulated conductor cable in jointing and the right-hand member of insulation heating cable and has filled magnesia powder, and two ends all arrange a joint end cap outside jointing.
The beneficial effects of the utility model are: high temperature resistant, the applicable place that needs laser heating, expanded the scope of application, and it uses coefficient of safety high, long service life, structural design is simple, easy for installation.
Accompanying drawing explanation
Fig. 1 is product structure schematic diagram of the present utility model.
embodiment:
In embodiment, the utility model is described in further detail below
As shown in Figure 1: a kind of New Mineral insulation heating cable connector: by insulated conductor cable 1, insulation heating cable 2, jointing 3, magnesia powder 4 and joint end cap 5, formed, the left end of its insulated conductor cable 1 is embedded in jointing 3, the right-hand member of insulation heating cable 2 is embedded in jointing 3, it is embedded between the left end of the insulated conductor cable 1 in jointing 3 and the right-hand member of insulation heating cable 2 and has filled magnesia powder 4, and jointing 3 two ends, outside all arrange a joint end cap 5.
Mineral insulation leader cable 1 is filled magnesia powder 4 insulating barriers after welding by oxygen welding with mineral insulation heating cable 2 in jointing, magnesia powder 4 is not to fall tightly by knocking nature, but first put into jointing, then the extruding by cable is pressed in joint by magnesia powder 4 firmly, the highest magnesian bearing temperature is 1400 ℃, the temperature resistant grade of magnesia powder 4 insulating barriers is high, and heating property is good; Mineral insulated cable sheath 1 is welded and fixed and is connected with jointing employing argon arc welding, good sealing effect, and electrical insulation properties is good, and cable cover(ing) can bear the high temperature the same with cable cover(ing) with the joint of jointing 3, and maximum temperature reaches 750 ℃ of left and right.
Claims (1)
