Description

  The present invention relates to a module mounting connector, and more particularly to a connector used for securely mounting a camera module such as a mobile phone or a game machine on a printed circuit board at a relatively long interval.

  An electronic device such as a mobile phone or a game machine usually needs to connect the camera module and the circuit board of the mobile phone or game machine as a single unit through a connector, and an image signal acquired by the camera module is connected to the mobile phone via the connector. Alternatively, it can be transmitted to a circuit board of a game machine to perform related processing.

  The camera module is a very small component in order to meet the demand for development of miniaturization. For this reason, in order to attach the camera module to a position away from the printed circuit board by a certain height, a new type of connector having a large height (the camera module connectors described in this specification can all be abbreviated as connectors). ), And the space occupied by the connector must be reduced as much as possible due to space and structural limitations. Therefore, the contact terminal of the connector is sufficiently long and the contact terminal is elastically deformed. Is required to move and compress only in the height direction (or vertical direction), which makes the contact connection between the contact terminal of the connector and the camera module unreliable, and the camera module is inserted into the connector. In the shock vibration environment, the electrical connection is very easy to disconnect and is unreliable. Difficult to achieve.
