In the sealed connector at the end of the electric wire, the covering tube to maintain the insulating properties of the metal sleeve is made of a heat-shrinkable resin material with a heat-melting resin layer formed on the inner surface, so that it can be used after the wire is connected under pressure. It can be heated and shrunk to make it adhere tightly to the wires, and the watertightness of the wire connection can be maintained, so it has the advantage of being able to be used as a connector with less risk of electrical leakage even in humid areas. . Furthermore, since the part that fits into the metal sleeve has a small diameter in advance, it can be mechanically crimped onto the bare end of the wire easily, and there is no fear that the connector will separate from the end of the wire. In particular, since the inner surface of the covering tube is coated with a heat-melting resin or adhesive, it has extremely good sealing properties, and after the wire is connected, it can be covered again with a plastic bag or the like to ensure watertightness. It can be used as is without the need for maintenance operations, and the hermetically sealed state of the end of the small diameter part can be easily obtained by heat crimping, making it easy to manufacture in mass production. It has the effect of being suitable for
Moreover, even if the thin outer tube is damaged during crimping, there is no risk of the inner metal sleeve covered by the intermediate resin sleeve being exposed to the outside, and furthermore, since the outer tube is transparent, it is easy to check whether the crimping operation is good or not. This has the advantage of being visually confirmed.
