The frame portion 22 is a quadrangular frame formed integrally with the peripheral portion of the upper surface of the plate portion 21. The frame portion 22 corresponds to the planar shape and size of the CCD camera module 15 and has a function of determining the position of the CCD camera module 15 in the two-dimensional direction. Examples of the material of the insulating housing 20 include PPS (pol yp henylenesulfide ) .

  As shown in FIG. 5, the first film base 31 includes an insulating film 41 and an elastic body 42. The first film base 31 is attached to the upper surface of the plate portion 21 with a double-sided adhesive tape 51.

  The insulating film 41 is substantially rectangular and has four corners 41a. The corner portion 41 a contacts the corner portion of the frame portion 22. Thereby, the insulating film 41 is positioned with respect to the plate part 21. Examples of the material of the insulating film 41 include polyimide and PET (polyethylene terephthalate).

  The elastic body 42 is formed on the periphery of the insulating film 41 by mold-in molding. The elastic body 42 has a plurality of block-like portions 42a and a plurality of connecting portions 42b. The block-shaped part 42a supports the end part of the conductive path 72 of the connection film 70 described later. The connecting portion 42b connects the block-like portions 42a. Examples of the material of the elastic body 42 include a silicon-based gel.

  The plurality of conductive paths 72 are formed at four corners of the insulating film 71, respectively. The plurality of conductive paths 72 formed at each corner are parallel to each other and extend parallel to the diagonal line of the insulating film 72. The conductive path 72 is formed on the insulating film 71 by, for example, plating or sputtering of a metal such as copper or silver. Since the insulating film 71 is transparent, the conductive path 72 can be seen through from the back side.

  The connection film 70 is affixed to the insulating housing 20 with an adhesive (not shown) or a double-sided adhesive tape (not shown). At this time, the four corners of the connecting film 70 are bent so as to be wound around the four sides of the frame part 22, and the one end part 72a of the conductive path 72 is overlaid on the block-like part 42a of the elastic body 42 of the first film base 31, The other end portion of the conductive path 72 is overlaid on the block-like portion 42 a of the elastic body 42 of the second film base 32.

  In order to electrically connect the CCD camera module 15 to the printed wiring board 16 using the connector 1, first, the connector 1 is mounted on the upper surface of the printed wiring board 16 by the double-sided adhesive tape 52 as shown in FIG. . The double-sided adhesive tape 52 is formed with four holes 52a for exposing the terminal portions 16a of the printed wiring board 16.

  Next, the CCD camera module 15 is fitted into the insulating housing 20 via the double-sided adhesive tape 51. At this time, the frame portion 22 of the insulating housing 20 guides the outer peripheral surface of the CCD camera module 15, and the CCD camera module 15 is positioned with respect to the plate portion 21 of the insulating housing 20.

  As shown in FIG. 9, when the CCD camera module 15 is fitted to the connector 1, the one end portion 72 a of the conductive path 72 of the connection film 70 and the CCD camera module 15 are caused by the elasticity of the elastic body 42 of the first film base 31.

  Further, the elastic member 42 of the first and second film bases 31 and 32 makes the one end 72a of the connection film 70 conductive path 72 and the terminal portion of the CCD camera module 15 stably contact each other, and the connection film. 70 The other end portion 72b of the conductive path 72 and the terminal portion 16a of the printed wiring board 16 are in stable contact.

  The elastic body 42 is made of gel, and even if it is damaged, the elastic body 42 is formed on the insulating film 41, so that the elastic body 42 can be replaced with the insulating film 41. In addition, since the insulating film 41 is accurately positioned when the corner portion 41a of the insulating film 41 comes into contact with the corner portion of the frame portion 22 during this replacement operation, the elastic body 42 can be easily positioned with respect to the plate portion 21. And it can position correctly.

  In addition, since the elastic body 42 is separated from the insulating housing 20, the distance between the elastic body 42 and the frame portion 22 can be narrower than when the elastic body 42 and the insulating housing 20 are molded in. Accordingly, the connector 1 can be reduced in size.

  Furthermore, since the connector 1 is composed of a film-like member except for the insulating housing 20, the connector 1 can be thinned.

  Further, since the CCD camera module 15 is attached to the connector 1 with the double-sided adhesive tape 51, the CCD camera module 15 can be repeatedly attached to and detached from the connector 1.

  Furthermore, since the connector 1 is mounted on the printed wiring board 16 by the double-sided adhesive tape 52, the connector 1 can be repeatedly attached to and detached from the printed wiring board 16.

  Further, since the connecting film 70 is used, it is not necessary to round the bent portion as in the FPC, and the connecting film 70 can be attached to the insulating housing 20 in close contact with each other. Can be prevented from increasing in size.

  The connector 1 of this embodiment electrically connects the CCD camera module 15 and the printed wiring board 16, but the use of the connector of the present invention is not limited to this. For example, the printed wiring boards are electrically connected to each other. It can also be applied as a connector to be connected.
