Therefore, there is a problem that the cost becomes very high.

May not be possible. This is because the heat-shrinkable tube 4 is made of a connector material (PBT polybutyl terephthalate), so that the heat-shrinkable tube 4 is not sufficiently adhered to the connector 2 due to contamination by a release agent or the like attached to the surface of the connector. That's why. In addition, there is a problem that the cost increases if the cleaning is performed to remove the dirt on the surface of the connector 2.

ネクタの保護構造を提供している。According to the present invention, a connector is connected to an end of an electric wire, and a protective tube is provided on a group of electric wires remote from a connection position with the connector. A heat-shrinkable tube filled with a sealing material is interposed from the outer peripheral surface on the distal end side of the tube to the outer peripheral surface of the housing on the wire connection side of the connector, and the sealing material is filled and fixed in the gaps of the electric wires and thermally contracted. A protective structure for an electric wire connection side connector is provided, wherein the tube is shrunk so as to be in close contact with the outer peripheral surface of the upper protective tube and in close contact with the outer peripheral surface of the connector housing in a boot shape.

外周に密着させている。Specifically, the protective tube externally fitted to the electric wire is a corrugated tube, and one side of the heat-shrinkable tube filled with the sealing material is externally fitted to the distal end side of the corrugated tube. The valley is filled with a sealing material, and the gap between the tip of the corrugated tube and the tip of the connector housing is at least 10 mm.
With a dimension of 20 mm to 20 mm, this portion is filled with the sealing material between the wires, and the heat-shrinkable tube is brought into close contact with the outer periphery of the wire group.

してもコネクタ外周面より外れない。[0010] As described above, when a space is provided between the connector (corrugated tube or the like) and the connector, which are provided outside the wire group, and the required space is provided, the sealing material applied to the inner surface of the heat-shrinkable tube is heated at this portion. When heated to shrink the shrink tubing, the sealing material melts and fills between the wires, and is fixed to the wires. The sealing material and the heat-shrinkable tube are firmly fixed inseparably. Therefore, the connector connected to the end of the wire group also has the terminal connected to the wire end locked inside the connector, and the wire group and the connector are integrated, so the heat-shrinkable tube is tightly fixed to the wire group. This prevents the heat-shrinkable tube from coming off the outer peripheral surface of the connector. Further, since the heat-shrinkable tube itself is in close contact with the outer peripheral surface of the connector via the sealing material, even if an external force acts on the connector, it does not come off from the outer peripheral surface of the connector.

Since the heat-shrinkable tube coated with the sealant is covered, the sealant fills and adheres between the wires, and the heat-shrinkable tube itself adheres to the outer periphery of the wire group,
The electric wire group and the heat-shrinkable tube can be fixed, and the electric wire can be reliably protected, and the connector connected to the electric wire can be prevented from coming off from the heat-shrinkable tube.

Due to the close contact, the outer sheath of the electric wire, the connector housing, and the exposed electric wire between them are reliably protected by the heat-shrinkable tube, thereby preventing inundation and intrusion of pride. Therefore, the wire connection side of the connector, which has conventionally been difficult to protect, can be reliably protected, and the waterproof and dustproof effects can be achieved.
