Description

  The present invention relates to a camera module board mounting structure for mounting a camera module to a board.

  Conventionally, when attaching a camera module to a printed wiring board placed inside an electronic device such as a mobile phone, a camera module that is vulnerable to heat cannot be attached directly by soldering, so use a camera module mounting socket. They are connected to the printed wiring board.

  This camera module mounting socket is composed of a bottom plate portion and a peripheral wall arranged so as to rise from the periphery of the bottom plate portion, and includes a socket housing having a module housing portion whose upper surface is open, and a plurality of contacts supported by the socket housing. The camera module is inserted into the module housing portion and brought into contact with the terminal of the camera module and the contact, thereby connecting the camera module to the connection substrate through the contact.

The camera module is prevented from coming off by locking a retaining piece that is supported by the peripheral wall of the socket housing in a recess formed on the upper edge of the camera module and protrudes into the module housing (for example, (See Patent Document 1).

  However, in the conventional technology as described above, if a recess is provided in the upper edge of the camera module, the space in the camera module is narrowed. Therefore, in order to secure a space for accommodating the elements constituting the camera module. There has been a problem that the outer shape of the camera module has to be enlarged, which makes it difficult to reduce the overall size including the camera module mounting socket.

  Accordingly, an object of the present invention is to provide a camera module board mounting structure that can be miniaturized in view of the above-described problems of the prior art.

  In order to solve the conventional problems as described above and achieve the intended object, the invention according to claim 1 is a socket housing having a module housing portion in which a camera module is housed, and is supported by the socket housing. A socket for mounting a camera module having a plurality of contacts is attached to a connection board having a terminal pattern disposed on a surface portion so that the contact and the terminal pattern are connected, and the camera module is accommodated in the module A camera module in which a terminal arranged on the bottom surface of the camera module and the contact come into contact with each other by being inserted into the camera module, and the camera module is connected to the connection board via the camera module mounting socket. In the substrate mounting structure, the camera module protrudes to the side surface The socket housing is formed on the inner wall surface of the module housing portion, and has a vertically extending projection insertion groove that is open on the inner side where the locking projection is inserted, and projects into the projection insertion groove. It is a board mounting structure of a camera module comprising an elastic pressing piece locked to the upper edge of the stop protrusion.

  According to a second aspect of the present invention, in addition to the configuration of the first aspect, the socket housing includes a shield member that covers an outer surface thereof, and the elastic pressing piece is integrally supported on an upper edge of the shield member. It is characterized by that.

  The camera module board mounting structure according to the present invention includes a socket housing having a module housing portion for housing a camera module, and a camera module mounting socket having a plurality of contacts supported by the socket housing.

  As shown in FIG. 2, the camera module mounting socket 11 includes a socket housing 14 having a module housing portion 13 whose upper surface is open, and a plurality of contacts 15, 15... Supported by the socket housing 14. .. Are inserted into the module housing portion 13 so that the contacts 15, 15... Are connected to the terminal portions disposed on the bottom surface of the camera module 10.

  The socket housing 14 is formed of a synthetic resin material in a box shape having an upper surface opened with a flat bottom plate portion 16 and a peripheral wall 17 arranged so as to rise from the periphery of the bottom plate portion 16, and is surrounded by the bottom plate portion 16 and the peripheral wall 17. Thus, a module housing portion 13 is formed.

  In the peripheral wall 17, contact insertion grooves 18 opened downward are formed at predetermined intervals, and the contact pieces 15, 15... Are formed by press-fitting attachment pieces of the contacts 15 into the contact insertion grooves 18. It can be attached to the socket housing 14.

  The contact insertion groove 18 is opened on the lower side and the inner side, that is, on the module housing portion side, and slit-like contact mounting grooves 19 and 19 are formed on both side edges thereof.

  Further, on the inner wall surfaces of the module housing portion 13 facing each other, that is, the inner surface surfaces of the peripheral wall 17 facing each other, vertical projection insertion grooves 20, 20,.

  Further, the outer peripheral wall 17 is covered with a shield member 21 made of a conductive plate material. The shield member 21 is integrally provided with an elastic pressing piece 22 supported on the upper edge portion in accordance with the position of the protrusion insertion groove 20. I have.

  The elastic pressing piece 22 is bent from the upper edge of the shield member 21 and is arranged so as to protrude into the protrusion insertion groove 20, and the lower edge of the elastic holding piece 22 protrudes from the side of the camera module 10. It is to be locked to.

  In the bottom plate portion 16, contact avoidance holes 24, 24... Are arranged in parallel with the contact insertion groove 18 so as to be directed in a direction substantially orthogonal to one side around the bottom plate portion 16. .

  The contact 15 is connected to a longitudinally flat mounting piece 30, a terminal piece 31 bent from the lower end of the mounting piece 30, and a connecting piece 32 bent downward from the upper edge of the mounting piece 30. The elastic contact piece 33 is bent obliquely upward from the lower end of the piece 32, and is formed by punching a conductive plate such as a copper alloy plate into a predetermined shape and bending it.

  The attachment piece 30 is formed wider than the width of the contact insertion groove 18, and the side edge thereof is press-fitted into the contact attachment grooves 19, 19 formed on the side of the contact insertion groove 18, thereby fitting the socket. A contact 15 is attached to the housing 14.

  The elastic contact piece 33 is bent at its tip, and a contact portion 34 is formed on the upper surface thereof.

  The elastic contact piece 33 is formed on the bottom surface of the camera module 10 that protrudes from the bottom plate 16 side into the module housing portion 13 and is accommodated in the module housing portion 13 by attaching the mounting piece portion 30 to the socket housing 14. The contacted terminal portion is elastically contacted.

  The terminal piece portion 31 is bent from the lower edge of the attachment piece portion 30 and is connected to a terminal pattern formed on the connection substrate 12.

  The camera module 10 includes a box-shaped main body 40 in which an image pickup device such as a CCD or CMOS, other elements, and the like are accommodated, and a lens tube 41 that protrudes from the upper surface of the main body 40 and accommodates a lens therein. In addition, locking projections 23 project from the side surfaces of the main body portion 40, that is, the portion inserted into the module housing portion 13, at positions corresponding to the projection insertion grooves 20.
