Problems solved by technology

[0017] For this reason, the process of peeling off the insulating layer is required, which increases the manufacturing cost
[0018] In addition, since the insulation layer is peeled off, even if it is a part, it still has a bad influence on the life of the electromagnetic wave shielding layer.

Abstract

Provided is a seal structure which has a seal member integrally formed on a flexible wiring board without peeling out an insulating layer (top coat) of the flexible wiring board, has excellent sealing performance and can be manufactured at a low cost. The seal structure is composed of a housing wherein the flexible wiring board is inserted through, and the seal member, which is integrally formed with the flexible wiring board and seals a gap between the housing and the flexible wiring board. The flexible wiring board is composed of a base FPC composed of an elastic material, a patterned copper foil and an adhesive layer, a conductive electromagnetic shielding layer formed on the surface of the base FPC, and an insulating layer covering the surface of the electromagnetic shielding layer. The seal member is directly and integrally formed on the insulating layer by using a self-adhesive liquid rubber.

Description

technical field [0001] The present invention relates to a sealing structure. More specifically, it relates to a sealing structure that provides a waterproof structure for electronic equipment and connectors. Background technique [0002] Recently, miniaturization of waterproof connectors used in electronic devices such as mobile phones and wiring harnesses for automobiles has progressed, and at the same time, high waterproof performance has been sought. [0003] In order to make an electronic device composed of multiple spaces waterproof, and to make the housings constituting each space airtight, it is necessary to electrically connect each space with a flexible substrate or the like. [0004] At this time, the proposed method includes providing terminals on the wall surface of the housing that separates the spaces, connecting these terminals with wiring materials; The resulting gap between the material and the enclosure. [0005] However, the form in which the terminals ...
