Description

  The present invention relates to an electronic component connecting device formed by fixing a plurality of conductor patterns in a state of being sandwiched between resin films.

  An electronic component connecting apparatus of the above type is conventionally known, and such a connecting apparatus is generally abbreviated as FPC. FIG. 6 is a perspective view showing an example of a conventional electronic component connecting apparatus of this type, and FIG. 7 is a sectional view taken along line VII-VII in FIG. In the electronic component connecting apparatus 1A shown in these drawings, a plurality of conductor patterns 2A extending substantially parallel to each other are fixed in a state sandwiched between insulating resin films 3A and 4A. The end portions 5A and 6A in the longitudinal direction of these conductor patterns 2A are exposed to the outside, and as shown in FIG. 8, the end portions are inserted into connectors 9A and 10A of separate electronic components 7A and 8A. Both the electronic components 7A and 8A can be electrically connected through the conductor pattern 2A. Such an electronic component connecting device 1A has flexibility. FIG. 7 is a schematic cross-sectional view in which the thicknesses of the resin films 3A and 4A and the conductor pattern 2A are exaggerated and greatly shown.

  Also with the conventional electronic component connecting apparatus 1A, as shown in FIG. 8, when the electronic components 7A and 8A are arranged in a straight line, the electronic components can be electrically connected without any trouble. However, for example, as shown in FIG. 9, when the electronic components 7 </ b> A and 8 </ b> A are arranged in an orthogonal direction, the electronic component connecting device 1 </ b> A needs to be bent as shown in FIG. 9. Since the electronic component connecting apparatus 1A has flexibility, the electronic component connecting apparatus 1A can be bent as shown in FIG. 9, but the electronic component connecting apparatus 1A is strongly bent in this way. As a result, a large external force is applied to the ends of the electronic component connecting device 1A inserted into the connectors 9A and 10A, and the ends may be disconnected from the connectors 9A and 10A. In some cases, the conductor pattern 2A may be broken at the bent portion of the electronic component connecting apparatus 1A. Further, when the electronic component connecting device 1A is bent, the front and back of one electronic component connecting device portion 12A with the bent portion as a boundary is reversed, so that the end of the electronic component connecting device 1A is erroneously inserted into the connector 9A. There is also a fear.

  An object of the present invention is to provide an electronic component connecting apparatus that can eliminate the above-mentioned conventional drawbacks.

  In the present invention, a plurality of conductor patterns extending substantially in parallel to each other are fixed in a state of being sandwiched between insulating resin films, and each end portion in the longitudinal direction of the conductor pattern is exposed, and each end portion is separately provided. In the electronic component connecting apparatus having flexibility to electrically connect both electronic components through the conductor pattern by inserting each into the connector of the electronic component, the resin film portion between the adjacent conductor patterns A slit-like through hole extending along the conductor pattern is formed, and the electronic component connecting device region in which the through hole is formed is formed in a bellows shape so that it can expand and contract in the width direction. .

  According to the present invention, it is not necessary to bend the electronic component connecting device even if both electronic components electrically connected by the electronic component connecting device are arranged in an orthogonal direction. It does not come off the connector, the conductor pattern is broken, or the end of the electronic component connecting device is not inserted into the connector by mistake. Moreover, since the flexibility of the portion of the electronic component connecting device in which the slit-like through holes are formed is increased, each end of the electronic component connecting device can be easily inserted into each connector.

  Embodiments of the present invention will be described below in detail with reference to the drawings.

  FIG. 1 is a perspective view showing an example of an electronic component connecting apparatus 1 according to the present invention, and FIG. 2 is a sectional view taken along line II-II in FIG. As shown in these drawings, the basic configuration of the electronic component connecting device 1 of this example is the same as that of the conventional electronic component connecting device. That is, this electronic component connecting device 1 also has a plurality of linear conductor patterns 2 extending substantially parallel to each other, and each conductor pattern 2 is, for example, a copper foil printed on an insulating resin film 3. It is comprised by. Another insulating resin film 4 is laminated on the resin film 3 and the conductor pattern 2, and the plurality of conductor patterns 2 are fixed while being sandwiched between the insulating resin films 3 and 4. Moreover, the resin film 4 is not laminated | stacked on each edge part 5 and 6 of the longitudinal direction of the some conductor pattern 2, The each edge part 5 and 6 is exposed outside. Thus, since the electronic component connection apparatus 1 of this example is comprised by the thin resin films 3 and 4 and the thin conductor pattern 2, the whole electronic component connection apparatus 1 has flexibility. 2 is also a schematic cross-sectional view in which the thicknesses of the resin films 3 and 4 and the conductor pattern 2 are exaggerated and enlarged as in FIG.

  As shown in FIG. 4, each end portion in the longitudinal direction of the electronic component connecting apparatus 1 is inserted into the connectors 9 and 10 into the separate electronic components 7 and 8. Thus, the exposed end portions 5 and 6 in the longitudinal direction of the conductor pattern 2 are respectively inserted into the connectors 9 and 10 of the separate electronic components 7 and 8. In this way, the electronic components 7 and 8 are electrically connected via the plurality of conductor patterns 2. Examples of the electronic components 7 and 8 include a printed circuit board.

  The configuration described above is not different from the conventional electronic component connecting apparatus. A difference from the conventional electronic component connecting apparatus is that a slit-like through-hole 11 extending along the conductor pattern 2 is formed in the resin film portion between the conductor patterns 2 adjacent to each other, as shown in FIGS. And at least the region A of the electronic component connecting device 1 in which the through hole 11 is formed is formed in a bellows shape so that it can expand and contract in the width direction W of the electronic component connecting device 1. It is. As shown in FIG. 3, the cross section of the part of the electronic component connecting device 1 in which the through hole 11 is formed is formed in a continuous C-shape. In the illustrated example, a through hole 11 is formed in the central region A in the longitudinal direction of the electronic component connecting device 1. FIG. 3 is also a schematic cross-sectional view in which the thicknesses of the resin films 3 and 4 and the conductor pattern 2 are exaggerated.

  According to the above configuration, since the electronic component connecting device region A in which the through hole 11 is formed can be flexibly expanded and contracted in the width direction W, the electric component connecting device 1 can be electrically connected as shown in FIG. As shown in FIG. 4, the region A in which the through-hole 11 of the electronic component connecting device 1 is formed is in the width direction even when the electronic components 7 and 8 that are connected to each other are arranged in directions orthogonal to each other. It can be compressed and deformed flexibly. Therefore, a large external force is not applied to each end portion of the electronic component connecting device 1 inserted into each connector 9, 10, and the end portions are prevented from coming off from the connectors 9, 10. be able to.

  Moreover, since the electronic component connecting apparatus 1 is not bent as in the prior art, but compressively deformed in the width direction, the stress generated in each conductor pattern 2 can be kept small, and the conductor pattern 2 is prevented from breaking. can do.

  Furthermore, since it is not necessary to reverse the front and back of the electronic component connecting device 1, the end of the electronic component connecting device 1 is not erroneously inserted into the connectors 9 and 10.

  Further, by forming the through hole 11 and forming the region A in which the through hole 11 is formed in a bellows shape, the flexibility of the electronic component connecting device 1 is increased. The part can be inserted into each connector 9, 10. Moreover, the bending radius R of the electronic component connection apparatus 1 shown in FIG. 4 can be adjusted by appropriately determining the length of the slit-shaped through hole 11.

  Furthermore, as shown in FIG. 5, in the case where both electronic components 7 and 8 are arranged so as to face each other with their positions shifted, the two regions A and B of the electronic component connecting apparatus 1 are If the through holes 11 are formed and the regions A and B are formed in a bellows shape, the electronic components 7 and 8 can be electrically connected without accompanying the conventional drawbacks.
