Problems solved by technology

[0007] The above-mentioned conventional waterproof plug has a concern of creating a gap between the bent electric wire and the resin member
In addition, when avoiding such concerns by making the resin member thicker over the entire circumference and reducing the bending range of the electric wire, there is a risk of lowering the waterproofness due to a decrease in the rubber filling factor which is the ratio of the rubber to the electric wire insertion hole

Abstract

A waterproof plug capable of improving waterproofness is provided. In a waterproof plug 1, the outside and the inside of a cylindrical resin member 2 are provided with a sealing section 3 including an outer circumference section 30 which intimately contacts to an inner wall face of a cavity 41 existing within a connector housing 4, and an inner circumference section 33 which intimately contacts to an outer circumference face of an electric wire 5, the electric wire 5 pulled out of the cavity 41 being inserted into the inner circumference section 33, and a contacting section 21 a of the resin member 2 is brought into contact with an inner wall face of an edge section 41 a of the connector housing 4 in which the electric wire 5 is pulled out of the cavity 41. The resin member 2 is provided with a plurality of protruded claw sections 211 protruding toward the side of the inner circumference section 33 along the circumference direction.

Description

technical field [0001] The invention relates to a waterproof plug. Background technique [0002] In the waterproof plug disclosed in the following Patent Document 1, a cylindrical resin member is buried to surround the covered electric wire, and when the electric wire is bent, contact between the electric wire and the electric wire insertion hole of the shield case is avoided by bringing the electric wire into contact with the resin member. The direct contact of the wire and the sliding contact between the wire and the wire insertion hole prevent the wire from being damaged. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Document JP-A-2009-123584 [0006] The technical problem that the present invention intends to solve [0007] The above-mentioned conventional waterproof plug has a concern of creating a gap between the bent electric wire and the resin member. Furthermore, when avoiding such concerns by making the res...
