Embodiment Construction

[0062] Below, based on Figure 1 to Figure 5 ,as well as Figure 10 , a preferred embodiment for carrying out the present invention will be described.

[0063] figure 1 is a diagram showing an example of a sealing structure to which the present invention is applied, figure 2 is the first embodiment of the present invention, image 3 shown with the existing example of Figure 6 same place, yes figure 2 The B-B section diagram.

[0064] exist figure 1 Among them, at both ends of the flexible wiring board 1, sealing members 3, 3 having different shapes are integrally formed.

[0065]The upper sealing member 3 in the figure forms a casing-shaped sealing member 31 that simultaneously seals the gap between the housings and the gap with the flexible wiring board 1, and the lower sealing member 3 in the figure forms a seal between the insertion hole provided in the housing and the flexible wiring board. A sleeve-shaped seal 32 for the gap of the wire substrate 1 .

Abstract

To eliminate rubber burr formation at the time of molding and to make sealing members to be surely integrated with the flexible wiring board, a sealing structure consists of housings to which the flexible wiring board is inserted, and sealing members integrally formed on the flexible wiring board to seal gaps between the housings and the flexible wiring board, the flexible wiring board consists of a base board made of an elastic material, a conductive printed wiring layer formed on the surface of the base board, and a cover film covering the surface of the printed wiring layer, and dummy printed wiring layers are arranged in regions where the sealing members are integrated with the flexible wiring board, so as to make a shape as if the printed wiring layer exists substantially over the entire base board in the width direction.

Description

technical field [0001] The present invention relates to a sealing structure. [0002] More specifically, it relates to a sealing structure providing a waterproof structure of an electronic device or a connector. Background technique [0003] Recently, waterproof connectors used in electronic devices such as mobile phones and harnesses for automobiles have been miniaturized, and high waterproof performance is required. [0004] In order for an electronic device composed of multiple spaces to have a waterproof function, it is necessary to make the casing constituting each space airtight, and to electrically connect each space through a flexible substrate or the like. [0005] In this case, there have been proposed methods of providing terminals on the wall surface of the housing that separates the spaces and connecting these terminals with wiring material, and of passing the wiring material through the wall surface of the housing and filling the wiring material with an adhesi...
