  • Publication number: 20040247311
    Abstract: A mounting structure is disclosed that is capable of reliably installing a compact camera module into a socket while maintaining a good electrical connection between them. The mounting structure includes an electrode pad formed in a lower portion of the compact camera module, a contacting member having a contacting end and a springy portion disposed in the socket, and a depressed portion formed on the lower portion of the compact camera module to accommodate the springy portion of the contacting member so that the lower portion of the compact camera module does not make contact with the springy portion of the contacting member when the lower portion of the compact camera module is inserted into the socket. Therefore, the springy portion supplies a sufficiently large springy force to reliably bright the contacting end into contact with the electrode pad, and this maintains a good electrical connection between the contacting end and the electrode pad.
