Description
Technical Field
The utility model relates to an auxiliary for lamps and lanterns especially relates to a waterproof power cord for lamps and lanterns.
Background
At present, outdoor lamps such as projection lamps and mining lamps are increasingly applied outdoors. One end of the power line of the project lamp after leaving the factory usually needs a terminal customer to connect a plug, but is limited to the capability of the terminal customer, and generally adopts the simplest and most convenient mode to connect the plug, so that the waterproof effect is poor. The current power cord generally includes three wires and the rubber layer of parcel in three wire outsides as live wire, zero line and ground wire respectively, and in rainy day, steam can get into in the connection gap of power cord and plug, and the gap between the copper line in insulation layer surface and the wire through the wire permeates into the projecting lamp in, can form the drop of water in the projecting lamp, and the drop of water can adsorb on the glass cover of projecting lamp, and the illumination effect of projecting lamp has seriously been influenced in the existence of drop of water.
Disclosure of Invention
The utility model aims to solve the technical problem that a waterproof power cord is used to lamps and lanterns is provided, it can block in steam passes through the power cord gets into lamps and lanterns, has improved the illumination effect of lamps and lanterns.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a waterproof power cord is used to lamps and lanterns which characterized in that: comprises a nylon inner core die, the nylon inner core die is provided with three axial through holes, a metal conductive tube is tightly arranged in each of the three axial through holes, both ends of the metal conductive tube are respectively welded with a wire, the 1 st metal conductive tube and the wires welded at both ends thereof form a live wire, the 2 nd metal conductive tube and the wires welded at both ends thereof form a zero wire, the 3 rd metal conductive tube and the wires welded at both ends thereof form a ground wire, the nylon inner core mould, the live wire, the zero wire and the ground wire are externally injected with nylon to form a nylon outer protective layer, one end of the live wire, one end of the zero line and one end of the ground wire which are at the same side extend out of the nylon outer protective layer and are used for being connected with the electrical part of the lamp, the other ends of the live wire, the zero line and the ground wire extend out of the nylon outer protective layer and are used for connecting a plug.
The two ends of the metal conductive tube are hollowed out, so that the middle part of the metal conductive tube is of a solid structure, the two end parts of the metal conductive tube are of a hollow structure, and the end head of the lead extends into the hollow structure and is welded with the hollow structure. The two ends of the metal conductive tube are hollowed to form a hollow structure, and then the end of the wire is stretched into the hollow structure and then welded, so that the welding of the wire is more reliable.
the metal conductive tube is a copper tube. The copper tube is selected as the metal conductive tube, so that the conductivity is good.
The nylon inner core die is cylindrical. The cylindrical nylon inner core die is easy to be injection molded and convenient to process.
Compared with the prior art, the utility model has the advantages of:
The power line with the structure has excellent waterproof performance, and because the live wire, the zero line and the ground wire are respectively provided with one section of the metal conductive tube, water vapor enters the power line through gaps among copper wires in the wires and then is blocked by the metal conductive tubes, and cannot enter the lamp; because the nylon protective layer is injection moulding outside nylon inner core mould and live wire, zero line and ground wire, all gaps between the wire have been filled to nylon promptly, consequently the insulating layer surface's of wire steam is blocked by the nylon protective layer, can not get into in the lamps and lanterns again to the illumination effect of lamps and lanterns has been improved.
