Description

  The present invention relates to a camera module socket for attaching a small camera module mainly to an electronic device such as a mobile phone.

  Generally, a camera module socket is used to incorporate a small camera module into an electronic device such as a mobile phone. In this conventional camera module socket, especially when used for a small electronic device such as a mobile phone, when there is not a sufficiently high accommodation space on the surface side of a printed wiring board (hereinafter referred to as a board) to which the socket is attached, A so-called window-hole mounting method is adopted in which a socket mounting window hole is opened through the substrate and the lower end side of the socket is inserted and mounted therein (for example, Patent Documents 1 and 2).

  This type of conventional camera module socket uses a housing molded with an insulating synthetic resin (mold housing), and the mold housing has front and rear walls raised from four sides of a rectangular bottom plate portion. It is integrally formed with a peripheral wall made up of a wall part and left and right wall parts, and is formed into a box shape with an open top that is square overall, incorporating the necessary contacts into this mold housing, and a peripheral wall made up of a bottom plate and front, rear, left and right wall parts The shielding material was attached to the arrangement | positioning which covers an outer side.

  In addition, in the case of mounting by the above-described window hole drop-in type, a method of soldering the terminal portion of the contact protruding from the housing to the pattern terminal portion provided on the edge surface of the window hole of the substrate is adopted. In this case, the terminal for connecting the board is projected from the intermediate height position of the peripheral wall of the housing.

  As described above, the conventional camera module uses a housing molded in a box shape and shields the outside by covering it with a shielding material. Therefore, the thickness of the entire peripheral wall must be increased. For this reason, there is a problem that a mounting window hole for mounting on the substrate becomes large and a large space is required for the substrate.

  Further, in the window hole drop-in type mounting method, there is a problem that the shape of the shielding material is complicated and the number of parts is large because the terminal connected to the substrate needs to protrude to the intermediate height position of the peripheral wall.

  Furthermore, when manufacturing a product with a different mounting height with respect to the board, there is a problem that the number of parts that require a design change for that purpose is large and the cost is high.

  In view of the conventional problems as described above, the present invention can reduce the size of the mounting window hole to be opened in the substrate, reduce the number of components and lower the manufacturing and assembly cost, and reduce the number of components to change the substrate. It is an object of the present invention to provide a camera module socket that can be easily changed in mounting height with low cost.

  The feature of the invention according to claim 1, which solves the conventional problems as described above and achieves the initial object, is a rectangular bottom plate portion and front and rear wall portions raised upward from four sides around the bottom plate portion. And a housing having an upper open type camera module housing portion surrounded by the left and right wall portions, contacts are supported on the front and rear wall portions of the housing, and contact pieces of the contacts with respect to the modules are arranged from the bottom plate portion to the upper surface thereof. And the board side connection terminals of the contacts are juxtaposed at a desired height position on the outer surface of the front and rear wall portions, and the housing shields the bottom plate portion, the left and right wall portions, and the front and rear wall portions with a shielding material. In addition, the upper side of the contact terminal on the board side of the contact protruding from the front and rear wall portions is shielded by a shielding material, and the lower part of the housing with respect to the board is placed on the board In the camera module socket for fixing by insertion into the through opening is allowed socket mounting window hole on the front and back,
