[ background of the invention ]

The production process of the existing high-waterproof lamp string connecting wire system for light supplement generally comprises the steps of directly connecting fixed lamp holder binding posts into wire cores of electric wires in parallel, and then placing a lamp holder on a mold to form an outer wide structure which can be held by fingers through injection molding by using PVC materials. The production process is simple, the cost is low, but along with the development of social economy and the use requirements of different areas, the requirements of people on products are not only low in price, but also the quality and the safety of the products are emphasized, after the traditional lamp string wire is subjected to injection molding, the lamp holder shrinks seriously after being directly irradiated by sunlight, water easily enters, the wind and rain are larger, the sunlight is more, the phenomenon of water entering is more serious, the light bulb is not bright, and the serious people have the danger of short circuit and electric leakage.

In addition, the binding post of lamp stand in the use continuously generates heat because of load electric charge, and especially the terminal is higher with the sinle silk junction of electric wire, and if electric charge transships, this department temperature rise phenomenon is more obvious. If the wind is strong, the wire core has a displacement phenomenon, and the risk of short circuit is increased. The sheath material of the electric wire is chlorinated polyethylene (thermosetting vulcanized rubber), the injection molding material of the shell is PVC (thermoplastic plastics), the two material molecules are different essentially, and a gap exists at the joint of the injection molding shell and the electric wire. After the wind blows and is sunned, the gap is enlarged, the water inlet degree is intensified, and the short circuit and electric leakage danger is increased.
