Description
Technical field
The present invention relates to a kind of connecting wire structure of electrical equipment, is more specifically a kind of electrical appliance connecting wire waterproof construction, belongs to electrical engineering and electric apparatus technical field.
Background technology
Some electrical equipment such as light fixture, electric heater can produce heat when work, thereby make its temperature increase.The wire that connects these electrical equipment generally comprises several electric wires, and electric wire comprises conductive cores and have insulating barrier outward in each conductive cores, and at several electric wires, be also provided with sheath outward, wire, in electrical equipment junction, need remove sheath.During due to electrical work, produce heat, make its temperature increase, near also corresponding rising of the temperature of the environment electrical equipment junction of wire, air is expanded, but after closing electrical equipment, temperature reduction along with near the environment electrical equipment junction of wire, air shrinks, due to air pressure reason, air can enter into along the space between jacket inner wall and electric wire outer wall near the electrical equipment junction of wire, a small amount of also can enter into along the space between conductive cores and insulating barrier near the electrical equipment junction of wire, when near the electrical equipment junction of wire, temperature is reduced to lower than dew point temperature, can bear water in the electrical equipment junction of wire, the easy like this use to electrical equipment brings potential safety hazard, also affected the useful life of electrical equipment simultaneously.
Utility model content
For above-mentioned situation, the problem that quasi-solution of the present invention is determined is to provide a kind of after closing electrical equipment, is not easy the electrical appliance connecting wire waterproof construction that bears water in the electrical equipment junction of wire, to guarantee the use safety of electrical equipment, the useful life of improving electrical equipment simultaneously.
For achieving the above object, the present invention has adopted following technical scheme: a kind of appliance wiring waterproof construction, described electrical appliance connecting wire comprises several electric wires, described electric wire comprises conductive cores, in each conductive cores, there is insulating barrier outward, at several electric wires, be also provided with sheath outward, on described electrical appliance connecting wire, there is electrical equipment junction, the electrical equipment junction of described electrical appliance connecting wire is provided with overcoat, and one end of described overcoat coordinates with the periphery of sheath end, the other end is expanded gradually to the direction extension of electrical equipment junction and the diameter of electrical appliance connecting wire; In described overcoat, be provided with electric wire separation frame, on described electric wire separation frame, there is several wiring region, in described each wiring region, there is a wire; Between described electric wire separation frame and overcoat, be provided with the marine glue of insulation.
As improvement, each electric wire in described overcoat is provided with the interval that insulate, described in go the to insulate conductive cores of interval exposed in the marine glue of insulation.
The expansion of described overcoat is: the angle α between described overcoat wall and electrical appliance connecting wire axis is 5-30 degree.The marine glue of described insulation is organic silicon water-proofing fluid sealant or poly-sulphur waterproof gasket cement or polyurethane water-proof fluid sealant or PVC waterproof gasket cement or the water base waterproof gasket cement of EVA.
Adopt such scheme, electrical appliance connecting wire waterproof construction of the present invention, after closing electrical equipment, temperature reduction along with near the environment electrical equipment junction of wire, air shrinks, owing to being provided with electric wire separation frame in overcoat, in each wiring region, thering is a wire, and between electric wire separation frame and overcoat, be provided with the marine glue of insulation.Cut off like this near air enters into the electrical equipment junction of wire along the space between jacket inner wall and electric wire outer wall, even temperature reduces near the electrical equipment downlink connection place of wire, also can avoid bearing water in the electrical equipment junction of wire, guaranteed like this use safety of electrical equipment, also can improve the useful life of electrical equipment simultaneously.
In addition, in improvement project, each electric wire in described overcoat is provided with the interval that insulate, described in go the to insulate conductive cores of interval exposed in the marine glue of insulation, air duct between conductive cores capable of blocking like this and insulating barrier, is conducive to avoid the electrical equipment junction of wire to bear water more.
Accompanying drawing explanation
Fig. 1 is the structural representation of electrical appliance connecting wire waterproof construction of the present invention;
Fig. 2 is that Figure 1A-A is to sectional structure chart;
Fig. 3 is the structural representation of another embodiment of electrical appliance connecting wire waterproof construction
In figure: 1-conductive cores, 2-insulating barrier, 3-sheath, the electrical equipment junction of 4-connecting line, 5-overcoat, 6-electric wire separation frame, 7-wiring region, 8-marine glue, 9-removes the interval that insulate.
Embodiment
As shown in Figure 1 and Figure 2, electrical appliance connecting wire waterproof construction of the present invention, described electrical appliance connecting wire comprises several electric wires, described electric wire comprises conductive cores 1, outside each conductive cores 1, there is insulating barrier 2, outside several electric wires 2, be also provided with sheath 3, have electrical equipment junction 4 on described electrical appliance connecting wire, said structure is identical with the structure of the electrical appliance connecting wire of prior art.
The feature of electrical appliance connecting wire waterproof construction of the present invention is: the electrical equipment junction 4 of described electrical appliance connecting wire is provided with overcoat 5, and one end of described overcoat 5 coordinates with the periphery of sheath 3 ends, the other end is expanded gradually to the 4 directions extensions of electrical equipment junction and the diameter of electrical appliance connecting wire.The expansion of described overcoat 5 is: the angle α between described overcoat 5 walls and electrical appliance connecting wire axis is 5-30 degree.
