Weatherproof light string

A method for manufacturing light string, comprising the steps of:

• cutting the first cable of predetermined length from raw material cable;
• stripping the outer sheath of the first cable from the first cable at two opposite ends to expose the insulation core wires A, stripping the insulation layers of the insulation core wires A from the insulation core wires A exposed at the two ends to expose the conductors, mechanically connecting the conductors of the insulation core wires A at the two ends to the conductive prongs of the male and female plugs respectively, and forming the male and female plugs by plastic injection molding;
• at the predetermined spacing, stripping the outer sheath from the first cable a predetermined length, to expose the insulation core wires A therein;
• positioning the insulation core wires A of the first cable and the insulation core wires B of the first cable in the T-shaped inner frame correspondingly in polarity, and mounting the T-shaped inner frame assembled with the positioned and overlapped insulation core wires to a nailing machine, so as to impact the conductive pins into the insulation core wires A and B at where they are overlapped;
• forming the sealing T-shaped connector on the T-shaped inner frame with the conductive pins impacted by plastic injection molding, wherein the T-shaped inner frame and the conductive pins are completely covered within the sealing T-shaped connector;
• repeating the positioning and forming steps to complete the connections between the first cable and all of the second cables and to form all of the sealing T-shaped connectors, and cooling the resulting light string in the air to ordinary temperature.
