Description

  The present invention relates to a camera-equipped mobile phone, and more particularly to a camera module fixing structure.

  In order to reduce the size of the camera-equipped mobile phone, the camera unit is arranged in a notch provided in the circuit board arranged in the second housing, and the circuit in the camera unit and the circuit board are arranged. There is known one that is electrically connected by connecting a connection terminal attached to the tip of a flexible substrate of a camera unit and a terminal portion of a circuit board (for example, see Patent Document 1).

The solid-state imaging device (camera module) includes a solid-state imaging device, a lens barrel that supports the imaging lens and the optical filter, and a substrate on which the solid-state imaging device and the lens barrel are fixed. It is known to be mounted on a mobile phone by being inserted into the positioning part of the telephone case, with the top surface of the main body of the lens barrel being in contact with the positioning part, and the pin being inserted into the positioning part of the mobile phone case. (For example, refer to Patent Document 2).

  However, in order to reduce the thickness of the camera-equipped mobile phone, when the connector cannot be arranged on the board closest to the camera module due to the mounting arrangement relationship of the mounting object or structure, a key is provided on one side of the main board, etc. Then, in the arrangement relationship in which the other electrical components are mounted on the other side, the connector of the main board cannot be provided on the side where the key of the main board is provided due to space restrictions. You have to lengthen the length. For this reason, there has been a problem that workability is poor because a long flexible substrate is hung when assembling a mobile phone. Therefore, when the camera module is attached to a mobile phone, it is desired that the camera module can be temporarily set in order to facilitate assembly work.

  If the camera module is temporarily installed, adding a mounting member such as resin makes it easy to obtain the accuracy of the shape and dimension. As a result, the mounting of the camera module is facilitated. Since this requires a space near the camera module, the size of the mobile phone becomes large and may become thick in some cases.

  The present invention has been made in order to solve such a conventional problem, and while making the mobile phone with a camera smaller and thinner, it is possible to easily attach and assemble the camera module to the mobile phone. The purpose is to do.

  The camera-equipped mobile phone of the present invention includes a housing, a circuit board disposed in the housing, and a camera module, the circuit board has a mounting hole, and the camera module has a sheet metal for electromagnetic shielding, The clip portion provided on the sheet metal for the electromagnetic shield of the camera module is inserted and held in the mounting hole of the circuit board.

  With this configuration, the camera module can be temporarily held on the circuit board by inserting the clip portion of the sheet metal for electromagnetic shielding provided in the camera module into the mounting hole of the circuit board.

  In the camera-equipped mobile phone according to the present invention, the electromagnetic shielding sheet metal of the camera module abuts against a spring contact electrically connected to the circuit board, and abuts against a holding part on the surface opposite to the spring contact. It has a configuration.

  With this configuration, the electromagnetic shielding sheet metal of the camera module is electrically connected to the circuit board, and the camera module is positioned by the spring contact and the pressing member on the surface opposite to the spring contact.

  The camera-equipped mobile phone of the present invention has a configuration in which the camera module is fixed by being sandwiched between the positioning portions of the housing.

  With this configuration, the camera module is finally fixed by being sandwiched between the positioning portions of the housing.

  The camera-equipped mobile phone of the present invention includes a housing, a circuit board disposed in the housing, and a camera module, the circuit board has a mounting hole, the camera module has a sheet metal for electromagnetic shielding, The camera module is temporarily held on the circuit board without the need for a mounting member such as resin by having a configuration in which the clip portion provided on the sheet metal for electromagnetic shielding of the module is inserted and held in the mounting hole of the circuit board. Therefore, the camera module can be easily attached to the mobile phone casing and the mobile phone can be made smaller and thinner.
