Japanese Patent Laying-Open No. 2005-268019 (page 4, line 7 to line 20, FIGS. 1 and 2)

  The conventional socket requires four parts, that is, each contact 23, an insulator 25 that holds each contact 23, an outer case 24, and a mounting lid 26, so that the assembly process is complicated and the cost is high. It is. Furthermore, since the structure uses the insulator 25, the mounting height must be increased.

  Accordingly, the present invention aims to provide a socket that improves the drawbacks of the conventional socket and reduces the number of parts, thereby simplifying the assembly process, reducing the cost, and reducing the height. Is.

  The present invention employs the following means in order to solve the above problems.

  1. In a socket for connecting two connection objects, the socket 1 includes an accommodation part 1d for accommodating one connection object 3 and the other connection object 2, and a connection part 3a for the one connection object. Is integrally formed with a spring portion 1a that presses toward the connection portion 2a of the other connection object and an engagement portion 1b that engages with the engaged portion 2b of the other connection object. The connection object and the other connection object are accommodated in the accommodation part, and the engaged part and the engagement part engage with each other to connect the two connection objects.

  2. The socket according to 1 above, wherein the socket is made of metal, and the spring portion and the engaging portion are integrally formed.

  3. 2. The socket according to claim 1, wherein a plurality of the spring portions are formed in the socket, and each spring portion corresponds to a plurality of connection portions of the one connection object and a plurality of connection portions of the other connection object, respectively. .

  As is apparent from the description of the specification, the present invention has the following effects.

  1. Since the socket is composed of a single part, the assembly process is simple and the cost is low.

  2. Unlike the conventional socket, the socket of the present invention does not have an insulator and a contact, so that the mounting height of the socket can be reduced.

  3. The socket includes an accommodating portion that accommodates one connection object and the other connection object, a spring portion that presses one connection object toward the other connection object, and an engaged state of the other connection object. Since it has only the engaging part which engages with a part, a structure is simple and manufacture is easy.

  A socket for connecting the camera module of the third embodiment of the present invention to the FPC will be described.

  A first embodiment of the present invention will be described with reference to FIGS.

  1A to 1D are four views of the socket 1, and the metal socket 1 is formed into a quadrangular frame shape from a plate material by pressing (see FIG. 4). Fifteen contact springs 1a are respectively formed at the lower portions of the front and rear surfaces of the socket 1 by bending at a predetermined pitch. Each contact spring 1a is configured in a substantially L shape, and a bent tip portion of each contact spring 1a is located at the lower part of the socket 1 and corresponds to the terminal 2a of the camera module 2. In addition, a pair of engagement springs 1b are formed on the left and right side surfaces of the socket 1 by cutting and bending. Furthermore, a rectangular notch 1 c is formed at the lower part of the right side surface of the socket 1.

  2A to 2D are four views of a camera module 2 that is an example of an electronic component that fits into the socket 1. The camera module 2 is made of a synthetic resin, and has 15 terminals 2a at a predetermined pitch on both front and rear sides of the lower surface. In addition, rectangular cutouts 2b are formed from both upper corners of the left and right side surfaces of the camera module 2 downward.

  FIG. 3 is a front view of the FPC 3 adapted to the camera module 2. Fifteen pads 3 a are provided on both front and rear sides of the FPC 3. Each pad 3 a corresponds to the terminal 2 a of the camera module 2. Further, a narrow portion 3b is formed from the center on the right side of the FPC 3.

  FIG. 4 is a perspective view of the entire socket 1, camera module 2, and FPC 3.

  FIG. 5 is a perspective view of the socket 1, the camera module 2, and the FPC 3 in an exploded state.

  A method for fitting the socket 1, the camera module 2, and the FPC 3 will be described with reference to FIGS. 6 and 7.

  First, the FPC 3 is inserted diagonally from the lower side of the socket 1 so that each pad 3a of the FPC 3 faces upward, and the FPC 3 is positioned on the contact spring 1a as shown in FIG. It is accommodated in the accommodating portion 1 d of the socket 1. At this time, the narrow portion 3b of the FPC 3 is inserted in correspondence with the cutout portion 1c of the socket 1.

  Next, when the camera module 2 is accommodated in the accommodating portion 1d of the socket 1 in the direction of the arrow in FIG. 6, the fitting state shown in FIG. 7 is reached. At this time, each contact spring 1 a of the socket 1 is elastically displaced and presses each pad 3 a of the FPC 3 toward each terminal 2 a of the camera module 2. Accordingly, each terminal 2 a of the camera module 2 is connected to each pad 3 a of the FPC 3. Further, since each engagement spring 1b of the socket 1 is elastically displaced and engages with each notch 2b of the camera module 2, the camera module 2 is prevented from being detached from the socket 1.

  In the first embodiment, an FPC (flexible printed wiring board) is used as one connection object, but a normal printed wiring board or the like can be used.

  Moreover, although a camera module is used as the other connection object, not only high-frequency electronic components such as a camera module and an IC unit, but also semiconductor elements and other electronic components can be used.

  A second embodiment of the present invention will be described with reference to FIG. In the description of the second embodiment, description of the same points as in the first embodiment will be omitted, and different points will be described.

  Protrusions 1 e are formed on both front and rear surfaces of the resin socket 1. Holes 4 a are formed on both front and rear surfaces of the metal shell 4.

When the shell 4 covers the socket 1, the camera module 2 and the FPC 3,
Each hole 4 a of the shell 4 engages with each ledge 1 e of the socket 1.

  A third embodiment of the present invention will be described with reference to FIG. In the description of the third embodiment, description of the same points as in the second embodiment will be omitted, and different points will be described.

  Considering that the FPC 3 can be easily inserted into the socket 1, a notch 1 f is formed from the upper part of the right side surface of the resin socket 1 downward.

  Therefore, when the FPC 3 is accommodated in the accommodating portion 1 d of the socket 1 from above, the narrow portion 3 b of the FPC 3 is accommodated corresponding to the notch portion 1 f of the socket 1.
