Definitions
- the present invention relates to a seal structure.
- the present invention relates to a sealing structure that provides a waterproof structure for electronic equipment and connectors.
- waterproof connectors used for electronic devices such as cellular phones and automobile wire harnesses have been required to have high waterproof functions as the size of the connectors has been reduced.
- terminals are provided on the walls of the housing that divides each space, and the terminals are connected with wiring materials, or the wiring material is passed through the walls of the housing to bond the gaps between the wiring materials and the housing.
- a method of filling with an agent was proposed.
- the aspect in which the terminal is provided on the wall surface of the housing has a problem that the device becomes large.
- the method of filling the gap between the wiring material and the housing with an adhesive or the like has caused a problem that disassembly and reassembly are difficult.
- FIGS. 4 and 5 a mode in which a sealing member is integrally formed on a flexible wiring board has been proposed (Japanese Patent Laid-Open Nos. 2003-142836 and 2004-214 927). . '' The embodiment shown in FIG. 4 is integrally molded with a frame-shaped seal member 30 0 1 force corresponding to the shape of each nodling and udging (not shown).
- the flexible wiring board 1 ⁇ 0 extends through the respective seal members 3 0 1, and an electronic component is mounted in a region surrounded by the respective seal members 3 0 1.
- a bush-shaped seal member 30 3 is integrally formed with the flexible wiring board 100.
- This seal member 303 is attached to a through hole provided in each housing (not shown).
- the connectors 30 4 provided at both ends of the flexible wiring board 100 are electrically connected to the electrical components in the housing.
- the flexible layered wiring board with shield layer 100 shown in FIGS. 4 and 5 has the following structure.
- an elastic material such as polyimide, polyamide, polyester, liquid crystal polymer, or polyethylene naphthaleate makes the circuit pattern of copper foil a sandwich structure.
- Both sides of the base FPC have an electromagnetic shielding layer using silver paste.
- an insulating layer is formed on the surface of the electromagnetic wave shielding layer to protect the surface and to provide electrical insulation. This insulating layer is called a top coat and uses an alkyd resin.
- this insulating layer has poor compatibility with the seal members 30 1 and 30 3, and it is difficult to integrally fix the seal members 3 0 1 and 30 3 on the insulating layer. It was.
- Patent Document 1 Japanese Patent Laid-Open No. 2 0 0 3— 1 4 2 8 3 6
- Patent Document 2 Japanese Unexamined Patent Application Publication No. 2 0 0 4-2 1 4 9 2 7 Disclosure of Invention
- the present invention makes it possible to integrally form a sealing member on a flexible wiring board without peeling off the insulating layer (top coat) for the flexible wiring board, and has a good sealing performance and is manufactured at low cost.
- An object of the present invention is to provide a seal structure that can be used.
- Another object of the present invention is to provide a seal structure that can be easily assembled by eliminating the trouble of applying an adhesive treatment to the surface of the insulating layer. '' Means to solve the problem
- a housing through which a flexible wiring board passes, and a sealing member that is integrally formed with the flexible wiring board and seals a gap between the knowing and the flexible wiring board.
- the flexible wiring board includes a base FPC made of an elastic material, a conductive electromagnetic shielding layer formed on a surface of the base FPC, and an insulating covering the surface of the electromagnetic shielding layer.

- sealing members 3 and 3 having different shapes are integrally formed on both ends of the flexible wiring board 1. : '
- the upper seal member 3 in the figure is a frame-shaped seal 3 1 that seals the gap between the housing 2 and the gap between the flexible wiring board 1 at the same time. It is a push-shaped seal 3 2 that seals the gap between the through hole provided in the housing and the flexible wiring board 1.
- the flexible wiring board 1 has the following structure.
- the base FPC 11 generally has a polyimide-to-foil-polyimide sandwich structure.
- insulating layers 1 3 and 1 3 for protecting the surface are formed on the surfaces of the electromagnetic wave yield layers 12 and 12 '.
- This insulating layer 13 is called a top coat, and alkyd resin is used.
- the sealing members 3 and 3 are made of self-adhesive type rubber which is a self-adhesive liquid rubber.
- this self-adhesive silicone rubber Shin-Etsu Silicone Co., Ltd. X— 3 4— 1 2 7 7 A / B, X— 3 4— 1 5 4 7 A / B, X— 3 4— 1 4 6 4 AZB etc. It is.
