Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Example 1:

the utility model discloses a novel anti-siphon electric wire, as shown in fig. 1 to 3, include: the power cord 1 and the injection molding sealing part 2 arranged in the middle of the power cord 1, a plurality of core wires 9 are arranged in the power cord 1, the inter-wire insulation support 3 is arranged in the injection molding sealing part 2, the plurality of core wires 9 are respectively spaced by the inter-wire insulation support 3, and the core wires 9 at the inter-wire insulation support 3 are in an exposed state with the inner insulation layer removed; the line-to-line insulating support 3 and the power supply line 1 at the two ends of the line-to-line insulating support 3 are sealed and fixed into a whole by the injection molding sealing part 2.

Every 9 inside strand wires that are of heart yearn, every strand wire passes through the soldering mode welding, be about to the space in the strand wire seal tin will through the soldering mode welding, and the soldering adopts the crest welder to weld, welding efficiency is high, it is effectual to weld, realize the sealing of strand wire itself, 9 quantity of heart yearn are 3, the strand wire quantity is 3 promptly, correspond the zero line respectively, ground wire and live wire, be equipped with 3 insulating barrier 6 around the axle center equipartition on the insulating support 3 of line, 3 sets up respectively between insulating barrier 6 through welded strand wire.

Also, the length of the inter-wire insulation holder 3 is slightly longer than the length of the core wires 9 in the bare state where the inner insulation layer is removed, further completely spacing the core wires 9 apart.

And finally, the position of the line-to-line insulating support 3 on the power line is fixed through injection molding and is completely sealed to form an injection molding sealing part 2, the injection molding sealing part slightly exceeds the two ends of the power line with the outer insulating layer stripped during injection molding, the power line without the outer insulating layer stripped is reformed into a whole through injection molding, and the anti-siphon line is processed and produced, so that the effective sealing performance of the power line at the position of the injection molding sealing part 2 is ensured, and the siphon phenomenon is avoided.

In the prior art, a cut-off production method is usually adopted to realize the anti-siphon effect of a power line, namely, two ends of the cut-off power line are connected after an insulating layer is removed, are clamped by corresponding clamping blocks, are generally manually welded or connected with a hardware terminal for crimping, and finally form a fixedly connected sealing part in an injection molding mode; the production process of the mode is complex in process, and a large part of work needs to be finished manually; meanwhile, in the process of disconnection and reconnection, the situation of connection failure or dislocation is easy to occur, so that the tensile strength is reduced, the product is scrapped, and the quality of the produced anti-siphon wire product is poor; therefore, the siphon-proof line has high production efficiency, extremely high safety and reliability, stable quality and good siphon-proof effect.
