Abstract

The invention discloses a waterproof wire and a production technology therefor. The wire comprises a wire core and an insulating sheath. A gap between one or more segments of the wire core or the whole core wire and the insulating sheath is provided with a sealing glue layer. The sealing glue layer is formed through vacuum pumping and the sucking of waterproof glue, and can effectively prevent water from being sucked into equipment or a lamp tool from the wire core or the gap between the wire core and the insulating gap, and improves the waterproof performance. Moreover, the outer side of the insulating sheath is fixedly provided with an anti-bending sheath made of hard plastic materials through the technology of injection molding. The position of the anti-bending sheath is corresponding to the position of the sealing glue layer, so as to prevent the sealing glue layer from being bent and peeled, thereby preventing the sealing glue layer from losing efficacy after the sealing glue layer is bent, and improving the waterproof reliability.
