Abstract

An accessory 1 is mounted on a board 2, and a connector main portion 31 is formed by terminals 5 and a connector board 6, and one end portions of the terminals 5 are soldered to the board 2. A first sealing member 7 is provided at the connector main portion 31, and an inner housing 32, corresponding to the connector main portion 31, is formed within a receiving chamber 3e of a casing 3. A connector frontage portion 30a is formed at the casing 3. By mounting the board 2 on the casing 3, the first sealing member 7 is held in intimate contact with the inner housing 32 to seal the connector frontage portion 30a, and also a connector 30 is formed.

Claims

1. A sealing structure of an accessory module comprising:

an accessory mounted on a board; and

a connector main portion defined by terminals and a connector board, one end portions of said terminals are soldered to said board;

a first sealing member provided at said connector main portion;

an inner housing, corresponding to said connector main portion, formed within a receiving chamber of a casing; and

a connector frontage portion formed at said casing,

wherein when said board is mounted on said casing, said first sealing member is held in intimate contact with said inner housing to seal said connector frontage portion so as to form a connector.

2. A sealing structure of an accessory module according to claim 1, wherein the other end portions of said terminals project toward an opening of said connector frontage portion, and insertion holes, corresponding respectively to said terminals, are formed through said first sealing member, and said terminals are press-fitted into said insertion holes, respectively, so that said first sealing member is held in intimate contact with said connector board.

3. A sealing structure of an accessory module according to claim 1, further comprising:

a second sealing member is provided at a front portion of a mating connector secured to a cable, and when said mating connector and said connector are coupled together, the two are electrically connected together, and a front surface portion of said mating connector is held in intimate contact with said first sealing member provided at said connector, and said second sealing member, provided at said mating connector, is held in intimate contact with said inner housing of said casing to seal said connector.

4. A sealing structure of an accessory module according to claim 1, wherein at least one lip, comprising at least one ridge, is formed on at least one surface of said first sealing member, said lip enhancing a sealing performance of said surface.

5. A sealing structure of an accessory module according to claim 1, wherein when a cover is attached to said casing, a mating surface of said casing and a mating surface of said cover are abutted against each other, so that said accessory is sealed within said receiving chamber of said casing or a receiving chamber of said cover.

6. A sealing structure of an accessory module according to claim 1, wherein said accessory is a camera module which is equipped by a camera adapted to be mounted on an automobile.
