以下、本発明に係るフラットケーブルと電子部品との接続構造の実施の形態について、図面を参照しながら説明する。   Hereinafter, embodiments of a connection structure between a flat cable and an electronic component according to the present invention will be described with reference to the drawings.

（実施の形態１）
図１は実施の形態１に係るフラットケーブルと電子部品との接続構造を示す斜視図である。図１に示すように、実施の形態１では、フラットケーブル１のフラット導体２の箇所に電子部品３のリード４が重ねられ、接続子５によってリード４とフラット導体２が接続される。 (Embodiment 1)
1 is a perspective view showing a connection structure between a flat cable and an electronic component according to Embodiment 1. FIG. As shown in FIG. 1, in the first embodiment, the lead 4 of the electronic component 3 is overlaid on the flat conductor 2 of the flat cable 1, and the lead 4 and the flat conductor 2 are connected by the connector 5.

フラットケーブル１は、平行配置された複数本のフラット導体２に、プラスチックフィルム（ポリエチレンテレフタレートフィルム等）の張り合わせ又は押出被覆等により絶縁被覆２ａを施したものである。フラット導体２は例えば厚さ0.15ｍｍ、幅5.2ｍｍの銅テープである。また、電子部品３は例えばＬＥＤなどの光源素子を備え、図３に示すように２本のリード４を有している。本実施の形態においてリード４はＬ形に屈曲され板状に形成されている。接続子５は、図２に示すように、背板部５ａと、背板部５ａの両側面から下側（図２の下方向）に形成された突刺し片５ｂと、背板部５ａの幅方向（図１のフラットケーブル１の長手方向）に突出する突出片５ｃとから構成されている。なお、接続子５は一枚の金属板を打ち抜き、折り曲げ加工するなどして製造される。また接続子５の両側の突刺し片５ｂの間隔は、その間に電子部品のリード４が入る大きさに設定されている。   The flat cable 1 is obtained by applying an insulating coating 2a to a plurality of flat conductors 2 arranged in parallel by bonding or extrusion coating of a plastic film (polyethylene terephthalate film or the like). The flat conductor 2 is, for example, a copper tape having a thickness of 0.15 mm and a width of 5.2 mm. Further, the electronic component 3 includes a light source element such as an LED, and has two leads 4 as shown in FIG. In the present embodiment, the lead 4 is bent into an L shape and formed in a plate shape. As shown in FIG. 2, the connector 5 includes a back plate portion 5a, a piercing piece 5b formed on the lower side (downward in FIG. 2) from both side surfaces of the back plate portion 5a, and a back plate portion 5a. It is comprised from the protrusion piece 5c which protrudes in the width direction (longitudinal direction of the flat cable 1 of FIG. 1). The connector 5 is manufactured by punching and bending a single metal plate. Moreover, the space | interval of the piercing piece 5b of the both sides of the connector 5 is set to the magnitude | size which the lead | read | reed 4 of an electronic component puts in between.

電子部品３のリード４、４は、フラットケーブル１の絶縁被覆２ａを剥ぐことなく、複数のフラット導体２の位置の上にそれぞれ載置される。接続子５は突刺し片５ｂがリード４の両側に位置するように配置され、突刺し片５ｂはフラットケーブル１のフラット導体２を突き抜け、フラットケーブル１の裏側で内側に曲成してかしめられ、フラットケーブルと電子部品とが電気的に接続された接続構造を得る。   The leads 4 and 4 of the electronic component 3 are respectively placed on the positions of the plurality of flat conductors 2 without peeling off the insulating coating 2a of the flat cable 1. The connector 5 is arranged so that the piercing pieces 5b are located on both sides of the lead 4, and the piercing piece 5b penetrates the flat conductor 2 of the flat cable 1 and is bent and crimped inward on the back side of the flat cable 1. A connection structure in which the flat cable and the electronic component are electrically connected is obtained.

このとき、突出片５ｃは背板部５ａの幅方向（フラットケーブル１の長手方向）に延びているので、フラットケーブル１を曲げたときなど、フラットケーブル１に外力が掛かった場合でもフラットケーブルと電子部品のリードとの接続箇所（突刺し片５ｂがフラットケーブル１を突き抜け、フラットケーブル１の裏側で内側に曲成してかしめられている箇所）に、応力が直接加わることがない。   At this time, since the protruding piece 5c extends in the width direction of the back plate portion 5a (longitudinal direction of the flat cable 1), even when an external force is applied to the flat cable 1 such as when the flat cable 1 is bent, Stress is not directly applied to a connection portion (a portion where the piercing piece 5b penetrates the flat cable 1 and is bent and crimped inward on the back side of the flat cable 1) with the lead of the electronic component.

なお、リード４と接続子５の背板部５ａとが重ね合わされており、この重ね合わせ部を図１０に示すように、せん断接合により接合してもよい。せん断接合は、例えば、リード４と背板部５ａの重ね合わせ部の一部を平行又はほぼ平行にせん断してせん断部９を形成すると共に、せん断部９の間をその両側と段違いになるように凹ませることにより形成される。これによりリード４と背板部５ａは半田付けなしで強固に接合される。   In addition, the lead 4 and the back plate portion 5a of the connector 5 are overlapped, and the overlapped portion may be joined by shear bonding as shown in FIG. In the shear bonding, for example, a part of the overlapping portion of the lead 4 and the back plate portion 5a is sheared in parallel or substantially in parallel to form the shearing portion 9, and the shearing portion 9 is stepped on both sides. It is formed by being recessed. Thereby, the lead 4 and the back plate portion 5a are firmly joined without soldering.

As shown in FIG. 4, in the second embodiment, the lead 4 of the electronic component 3 is superimposed on the flat conductor 2 of the flat cable 1, and the lead 4 and the flat conductor 2 are connected by the connector 15.

この接続構造が図１に示した接続構造と異なる点は、接続子１５が、図５に示すように、背板部１５ａと、背板部１５ａの両側面から下側（図５の下方向）に形成された突刺し片１５ｂと、背板部１５ａの幅方向（図４のフラットケーブル１の長手方向）に突出する突出片１５ｃと、突刺し片１５ｂの反対側の背板部１５ａが突出片１５ｃを含めてコ字状に折り返されて形成された折り返し部１５ｄと溝部１５ｅから構成され、フラット導体２に重ねられたリード４に接続子１５の突刺し片１５ｂを重ねるとともに、接続子１５の溝部１５ｅにフラットケーブル１の幅方向縁端を収容されることである。   This connection structure is different from the connection structure shown in FIG. 1 in that the connector 15 has a back plate portion 15a and a lower side from both side surfaces of the back plate portion 15a as shown in FIG. ), A protruding piece 15c protruding in the width direction of the back plate portion 15a (longitudinal direction of the flat cable 1 in FIG. 4), and a back plate portion 15a opposite to the piercing piece 15b. It is composed of a folded portion 15d and a groove portion 15e formed by being folded back in a U-shape including the protruding piece 15c, and the piercing piece 15b of the connector 15 is superimposed on the lead 4 superimposed on the flat conductor 2, and the connector That is, the edge in the width direction of the flat cable 1 is accommodated in the 15 grooves 15e.

上記以外の構成は図１に示した接続構造と同じであるので、同一部分には同一符号を付して説明を省略する。なお、上記折り返し部１５ｄはフラットケーブル１に接続する前に予め形成しておいてもよく、突刺し片１５ｂがフラットケーブル１のフラット導体２を突き抜けフラットケーブル１の裏側で内側に曲成してかしめられる際に、加工してもよい。また、溝部１５ｅにフラットケーブル１の幅方向縁端を収容された後に、折り返し部１５ｄを背板部１５ａ側に押圧、圧縮又はかしめるなどして、背板部１５ａと折り返し部１５ｄとでフラットケーブルを挟み込むようにしてもよい。   Since the configuration other than the above is the same as that of the connection structure shown in FIG. The folded portion 15d may be formed in advance before being connected to the flat cable 1, and the piercing piece 15b penetrates the flat conductor 2 of the flat cable 1 and is bent inward on the back side of the flat cable 1. It may be processed when it is caulked. Further, after the edge in the width direction of the flat cable 1 is accommodated in the groove 15e, the folded back portion 15d is pressed, compressed, or caulked to the back plate portion 15a side so that the back plate portion 15a and the folded portion 15d are flat. You may make it pinch | interpose a cable.

（実施の形態３）
図６は実施の形態３に係るフラットケーブルと電子部品との接続構造を示す斜視図である。図６に示すように、実施の形態２では、フラットケーブル１のフラット導体２に電子部品３のリード４が重ねられ、接続子２５によってリード４とフラット導体２が接続される。 (Embodiment 3)
FIG. 6 is a perspective view showing a connection structure between the flat cable and the electronic component according to the third embodiment. As shown in FIG. 6, in the second embodiment, the lead 4 of the electronic component 3 is superimposed on the flat conductor 2 of the flat cable 1, and the lead 4 and the flat conductor 2 are connected by the connector 25.

この接続構造が図４に示した接続構造と異なる点は、接続子２５が、図７に示すように、背板部２５ａと、背板部２５ａの一部がコ字状に折り返されて形成された折り返し部２５ｄと溝部２５ｅから構成され、突刺し片や突出片が形成されていない点であり、リード４と接続子２５の背板部２５ａとが重ね合わされて、この重ね合わせ部をせん断接合により接合されていることである。   This connection structure is different from the connection structure shown in FIG. 4 in that the connector 25 is formed by folding the back plate portion 25a and a part of the back plate portion 25a into a U shape as shown in FIG. It is composed of the folded portion 25d and the groove portion 25e, and no piercing piece or protruding piece is formed. The lead 4 and the back plate portion 25a of the connector 25 are overlapped, and the overlapping portion is sheared. It is joining by joining.

せん断接合は、例えば、リード４と背板部２５ａの重ね合わせ部の一部を平行又はほぼ平行にせん断してせん断部９を形成すると共に、せん断部９の間をその両側と段違いになるように凹ませることにより形成される。これによりリード４と背板部２５ａは半田付けなしで強固に接合される。   In the shear bonding, for example, a part of the overlapping portion of the lead 4 and the back plate portion 25a is sheared in parallel or substantially in parallel to form the shearing portion 9, and the shearing portion 9 is stepped on both sides. It is formed by being recessed. Thereby, the lead 4 and the back plate portion 25a are firmly joined without soldering.

上記以外の構成は図４に示した接続構造と同じであるので、同一部分には同一符号を付して説明を省略する。なお、リード４と背板部２５ａの重ね合わせ部は図６に示すように背板部２５ａとフラットケーブル１の間にリード４を配置するほか、図８に示すようにフラットケーブル１、背板部２５ａ、リード４の順に重ねてもよい。また、折り返し部２５ｄは図７に示すようにフラットケーブル１に接続する前に予め形成しておいてもよく、図９に示すように背板部２５ａとは別体としてもよい。   Since the structure other than the above is the same as that of the connection structure shown in FIG. As shown in FIG. 6, the overlapping portion of the lead 4 and the back plate portion 25a is arranged between the back plate portion 25a and the flat cable 1 as shown in FIG. 6, as well as the flat cable 1 and the back plate as shown in FIG. The portion 25a and the lead 4 may be stacked in this order. Further, the folded portion 25d may be formed in advance before being connected to the flat cable 1 as shown in FIG. 7, or may be separated from the back plate portion 25a as shown in FIG.
