Embodiment Construction

[0038] refer to Figure 1 to Figure 4 , a connector according to an embodiment of the present invention and a method of integrally molding the same will be described.

[0039] The connector 1 in this embodiment includes: an electric wire 7 whose core 3 is covered with a sheath 5; a terminal 11 having a connecting portion 9 connected to the core 3 of the electric wire 7; surrounding cover 13 . In addition, the cover member 13 includes an elastic resin 15 and a resin 17, the elastic resin 15 being provided around the connecting portion 9 and the end portion of the outer skin portion 5 near the connecting portion 9, joined to the outer skin part 5 and is crimped to the terminal 11 at the same time, the resin 17 is provided around the elastic resin 15 so as to compress the elastic resin 15 and bond to the elastic resin 15 .

[0040] This method of integrally molding the connector 1 includes: a first step: injecting the elastic resin 15 around the connecting portion 9 and the end...

Abstract

Provided is a method for integrally forming a connector, by which the number of parts can be reduced and productivity can be improved. The method has: a first step wherein an elastic resin (15) is injection-molded around a connecting section (9) and a coating section (5) end portion positioned on the connecting section (9) side, and the coating section (5) and the elastic resin (15) are bonded to each other; and a second step wherein a resin (17) is injection-molded around the elastic resin (15) such that the elastic resin (15) shrinks, the elastic resin (15) and a terminal (11) are pressure-welded, and the elastic resin (15) and the resin (17) are bonded to each other.

Description

technical field [0001] The invention relates to a method for integrally forming a waterproof connector and a target connector. Background technique [0002] As a connector having waterproof performance, there is conventionally known a connector in which electric wires and a housing are integrally molded of thermoplastic resin, and joints between the respective parts are sealed with thermoplastic resin (for example, refer to Patent Document 1). [0003] In the above-mentioned connector, the waterproof performance of the connector side depends on the shape of a counterpart to be connected with the connector. In this connector, although it is not necessary to seal the mating part side depending on the kind of oil-proof etc., in some cases, unless the connector side is sealed, there is a possibility that oil, etc. may flow along the electric wire and cause damage. Spreading concerns. In the case where a sealing mechanism is required, it is more efficient to provide sealing per...
