Patent number: 8144243Abstract: The present invention relates to a camera module assembled by using a connector. The present invention provides a camera module including: a main substrate having an image sensor mounted on an upper surface and a connector insertion groove formed at one side of the image sensor; a plurality of connectors mounted in a row in the connector insertion groove; a housing mounted on the main substrate and having a lens barrel vertically movably coupled therein; a flexible printed circuit board mounted to surround an outer peripheral surface of the housing while being electrically connected to a lens transfer device coupled to one side of the housing; and a shield case coupled to the outer peripheral surface of the housing. Since it is possible to minimize a distance between pads which are connectable through the connector, there is an advantage of miniaturizing the camera module as a whole by size reduction of the main substrate.Type: GrantFiled: December 22, 2009Date of Patent: March 27, 2012Assignee: Samsung Electro-Mechanics Co., Ltd.Inventor: Hwan Jun Kang
