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

Provided is a waterproof plug with which waterproofness can be improved. In the waterproof plug (1), a sealing section (3) is provided with an outer circumference section (30) that adheres closely to inner wall faces of cavities (41) existing within a connector housing (4), and an inner circumference section (33) through which a wire (5) to be pulled out from the cavity (41) is inserted, and which adheres closely to an outer circumference face of the wire (5). The sealing section (3) is formed on the inner side and outer side of a cylindrical resin member (2). A contacting section (21a) of the resin member (2) is made to come in contact with an inner wall face of an edge section (41a) of the connector housing (4), from which the wire (5) is to be pulled out from the cavities (41). A plurality of protruded claw sections (211), protruding towards the inner circumference section (33) side, are formed on the resin member (2) along the circumference direction thereof.

Description

technical field [0001] The present 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 embedded to surround the covered electric wire, and when the electric wire is bent, the electric wire is prevented from coming into contact with the resin member between the electric wire and the electric wire insertion hole of the shielding case The direct contact of the wire and the sliding contact between the wire and the wire insertion hole are produced to prevent the wire from being damaged. [0003] prior art literature [0004] Patent Literature [0005] Patent Document 1: Japanese Patent Document JP-A-2009-123584 [0006] The technical problem to be solved by the present invention [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 the resin member is mad...
