Description

本発明は、自動車などに搭載される複数の導体が平面状に並設されたフレキシブルプリント基板等のフラット配線部材を使用したコネクタ及びジョイントボックス等の電気接続装置に関する。   The present invention relates to an electrical connection device such as a connector and a joint box using a flat wiring member such as a flexible printed circuit board in which a plurality of conductors mounted in an automobile or the like are arranged in a plane.

近年、自動車部品のモジュール化及び省スペース化に伴い、自動車などに搭載されるワイヤーハーネスとして複数の導体を平面状に並設したフラットハーネスが多用されるようになってきた。フラットハーネスを使用する場合、フラットハーネス同士を接続したり、フラットハーネスと補機等の電気接続部材とを接続するためのフラットハーネス用コネクタやフラットハーネス用ジョイントボックスが必要になる。フラットハーネス用コネクタは、従来のワイヤーハーネス用のコネクタとの互換性を優先し、接続端子の先端側は従来型コネクタとの嵌合が可能な形状をなし、基端側はフラットハーネス用コネクタの端末部と接続可能な平板状の形状をなしている。   In recent years, with the modularization and space saving of automobile parts, flat harnesses in which a plurality of conductors are arranged side by side as a wiring harness mounted on an automobile or the like have been frequently used. When the flat harness is used, a flat harness connector or a flat harness joint box for connecting the flat harnesses or connecting the flat harness and an electrical connection member such as an auxiliary machine is required. The flat harness connector gives priority to the compatibility with the conventional wire harness connector, and the distal end side of the connection terminal has a shape that can be fitted with the conventional connector, and the proximal end side is the flat harness connector. It has a flat shape that can be connected to the terminal.

このフラットハーネス用コネクタの構造については、例えば特許文献１に開示されている。ここに開示されたフラットハーネス用コネクタは、コネクタハウジングの内部に、フラットハーネスの各導体と接合された複数の接続端子が収容されている。これらの接続端子の各導体への接合方式としては、例えば接合部分に対して一対の電極を所定間隔を空けて当接し溶接する抵抗溶接（シリーズ溶接）などが多く行われている。   The structure of the flat harness connector is disclosed in Patent Document 1, for example. In the flat harness connector disclosed herein, a plurality of connection terminals joined to the respective conductors of the flat harness are accommodated inside the connector housing. As a method of joining these connection terminals to each conductor, for example, resistance welding (series welding) in which a pair of electrodes are in contact with and welded to a joint portion at a predetermined interval is often performed.

特開２００２−１７０６６１号公報（段落０００６、図１３）JP 2002-170661 A (paragraph 0006, FIG. 13)

上述した特許文献１に記載されているように、フラットハーネスの導体と接続端子とを抵抗溶接で接合した場合に、その接合部分は、例えば接続端子とフラットハーネスとをそれぞれ引っ張る方向の引張強度はある程度得られるものの、接続端子をフラットハーネスから引き剥がす方向の引き剥がし（ピール）強度は不十分であるという欠点がある。   As described in Patent Document 1 described above, when the conductor of the flat harness and the connection terminal are joined by resistance welding, the joint portion has, for example, the tensile strength in the direction of pulling the connection terminal and the flat harness, respectively. Although it can be obtained to some extent, there is a drawback that the peel strength in the direction of peeling the connection terminal from the flat harness is insufficient.

そのため、コネクタの根元部分に折れ曲がるような力が加わった場合、接続端子の基端部とフラットハーネスの端末部とが剥離する可能性がある。従って、特許文献１のものでは、接続端子とフラットハーネスの接合部分を、例えばホットメルト樹脂などでモールドすることにより、ピール強度の向上を図るように工夫している。   Therefore, when a bending force is applied to the base portion of the connector, the base end portion of the connection terminal and the terminal portion of the flat harness may be peeled off. Therefore, in the thing of patent document 1, it has devised to aim at the improvement of peel strength by molding the junction part of a connection terminal and a flat harness, for example with hot-melt resin.

しかしながら、上記特許文献１のようにフラットハーネスと接続端子との接合部をモールド樹脂で補強する場合、樹脂をモールドするための金型が必要になる他、樹脂モールド工程が入るため、コネクタの組み立てに時間がかかり、フラットハーネス用コネクタのコストアップに繋がるという問題がある。また、フラットハーネスと接続端子との接合部は、モールド樹脂で封止されるため、基本的に分解不可能であるという問題もある。   However, when the joint portion between the flat harness and the connection terminal is reinforced with a mold resin as in Patent Document 1, a mold for molding the resin is required, and a resin molding process is included, so that the connector is assembled. This takes time and leads to an increase in the cost of the flat harness connector. Moreover, since the junction part of a flat harness and a connection terminal is sealed with mold resin, there also exists a problem that it cannot fundamentally disassemble.

本発明は、このような問題点に鑑みてなされたもので、フラット配線部材と接続端子との接合部分のピール強度を向上させて機械的強度の信頼性を高めることができると共に組立作業性を向上させてコスト低減を図ることができ、しかも分解可能な電気接続装置を提供することを目的とする。   The present invention has been made in view of such problems, and can improve the peel strength of the joint portion between the flat wiring member and the connection terminal to increase the reliability of the mechanical strength and improve the assembly workability. An object of the present invention is to provide an electrical connecting device that can be improved in cost and can be disassembled.

本発明に係る電気接続装置は、平面状の導体を平面絶縁体上に設けたフラット配線部材と、基端部が前記フラット配線部材の導体の端末部と面接触により電気的に接続され先端部が他の電子部品と接続される接続端子と、前記フラット配線部材及び前記接続端子を支持する支持部材とを備えた電気接続装置において、前記支持部材が、前記フラット配線部材の導体の端末部と前記接続端子の基端部との接続部を前記フラット配線部材側から支持する第１の端末支持部と、前記接続部に前記接続端子側から当接して前記第１の端末支持部と共に前記接続部を挟持する第２の端末支持部とを備えたものであることを特徴とする。   The electrical connection device according to the present invention includes a flat wiring member in which a planar conductor is provided on a planar insulator, and a proximal end portion that is electrically connected to a terminal portion of the conductor of the flat wiring member by surface contact. In the electrical connection device including a connection terminal connected to another electronic component, and the flat wiring member and a support member that supports the connection terminal, the support member includes a terminal portion of a conductor of the flat wiring member A first terminal support portion that supports a connection portion with a base end portion of the connection terminal from the flat wiring member side, and a contact with the connection portion from the connection terminal side, together with the first terminal support portion, the connection And a second terminal support part for sandwiching the part.

なお、本発明における電気接続装置は、例えばコネクタハウジングやジョイントボックスであって、コネクタハウジングの場合、好ましくは、前記支持部材が、前記接続端子をその先端部及び基端部を外側に突出させた状態で支持する子ハウジングと、前記接続端子の先端部及び基端部が内部に収容されるように前記子ハウジングが装着されると共に、前記接続部の前記接続端子側の側面に開口部を有する親ハウジングとを有し、前記第１の端末支持部は、前記子ハウジングから前記接続端子の基端部に沿って延びる板状の支持部であり、前記第２の端末支持部は、前記親ハウジングの前記開口部から挿入されて前記接続部の前記接続端子側と当接するロック部材であることを特徴とする。
この場合、前記ロック部材は、前記子ハウジングが前記親ハウジングに完全装着された状態で前記接続端子の基端部が嵌合する溝部を有し、前記接続端子の基端部が前記溝部に嵌合した状態では前記開口部に完全挿入され、前記子ハウジングが前記親ハウジングに完全装着されていない状態では前記接続端子との干渉により前記開口部に完全挿入されないものであるとすることができる。 The electrical connection device according to the present invention is, for example, a connector housing or a joint box. In the case of a connector housing, preferably, the support member projects the connection terminal from the distal end portion and the proximal end portion to the outside. The child housing is mounted in such a manner that the child housing is mounted so that the distal end portion and the proximal end portion of the connection terminal are accommodated therein, and an opening is provided on the side surface of the connection portion on the connection terminal side. And the first terminal support portion is a plate-like support portion extending from the child housing along the proximal end portion of the connection terminal, and the second terminal support portion is the parent support portion. The lock member is inserted from the opening of the housing and is in contact with the connection terminal side of the connection portion.
In this case, the lock member has a groove portion into which the base end portion of the connection terminal is fitted in a state where the child housing is completely attached to the parent housing, and the base end portion of the connection terminal is fitted into the groove portion. In the combined state, it can be completely inserted into the opening, and in a state where the child housing is not completely attached to the parent housing, it cannot be completely inserted into the opening due to interference with the connection terminal.

また、本発明におけるフラット配線部材は、例えば絶縁フィルムなどの絶縁被覆上に導体をパターン形成して回路部を形成しこれらの上にカバーレイフィルムなどを形成したフレキシブルプリント基板（Flexible Printed Circuit：ＦＰＣ）や、平面状導体の押出成形により回路部を形成してこの回路部を絶縁フィルムなどの絶縁被覆でラミネートしたフレキシブルフラットケーブル（Flexible Flat Cable：ＦＦＣ）等である。   The flat wiring member according to the present invention is a flexible printed circuit (FPC) in which a conductor is patterned on an insulating coating such as an insulating film to form a circuit portion and a coverlay film or the like is formed thereon. ), A flexible flat cable (FFC) or the like in which a circuit portion is formed by extrusion molding of a planar conductor, and the circuit portion is laminated with an insulating coating such as an insulating film.

また、接続端子の基端部とフラット配線部材の導体の端末部とのそれぞれの接合方法としては、例えばシリーズ溶接などの抵抗溶接、超音波溶着、レーザ溶接、アーク溶接、半田付け又はピアッシングが挙げられる。   In addition, as a method for joining the base end portion of the connection terminal and the terminal portion of the conductor of the flat wiring member, for example, resistance welding such as series welding, ultrasonic welding, laser welding, arc welding, soldering or piercing can be cited. It is done.

本発明によれば、フラット配線部材及び接続端子を支持する支持部材が、フラット配線部材の導体の端末部と接続端子の基端部との接続部を、フラット配線部材側から支持する第１の端末支持部と、接続端子側から当接する第２の端末支持部とを備え、これら第１及び第２の端末支持部によって接続部をその両側から挟持するようにしているので、電気接続装置の基端部に折れ曲がるような力が加わっても、フラット配線部材と接続端子との接続部に引き剥がし方向の力が加わるのを防止することができる。これにより、フラット配線部材と接続端子との接合部分のピール強度を向上させて機械的強度の信頼性を高めることができる。また、モールド樹脂を使用せずに、第１の端末支持部と第２の端末支持部とにより接続部を両側から挟持する構造であるため、組立作業性が向上してコスト低減を図ることができると共に、簡単に分解することが可能となり、メンテナンスも容易に行うことが可能となる。   According to the present invention, the support member that supports the flat wiring member and the connection terminal supports the connection portion between the terminal portion of the conductor of the flat wiring member and the base end portion of the connection terminal from the flat wiring member side. Since the terminal support portion and the second terminal support portion abutting from the connection terminal side are provided, and the connection portion is sandwiched from both sides by the first and second terminal support portions, the electrical connection device Even if a force that bends the base end portion is applied, it is possible to prevent the force in the peeling direction from being applied to the connection portion between the flat wiring member and the connection terminal. Thereby, the peeling strength of the junction part of a flat wiring member and a connecting terminal can be improved, and the reliability of mechanical strength can be improved. In addition, since the connection part is sandwiched from both sides by the first terminal support part and the second terminal support part without using the mold resin, the assembly workability can be improved and the cost can be reduced. In addition, it can be easily disassembled, and maintenance can be easily performed.

以下、添付の図面を参照して、本発明の好ましい実施の形態を説明する。
図１は、本発明の一実施形態に係るフラットハーネス用コネクタを示す分解外観斜視図、図２は、このフラットハーネス用コネクタの外観斜視図、図３は、図２のＡ−Ａ´断面図である。 Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
1 is an exploded external perspective view showing a flat harness connector according to an embodiment of the present invention, FIG. 2 is an external perspective view of the flat harness connector, and FIG. 3 is a cross-sectional view taken along line AA ′ of FIG. It is.

図１に示すように、フラットハーネス用コネクタ１は、フラットハーネス５０と、このフラットハーネス５０の端末部と接続される複数の接続端子４０と、これら複数の接続端子４０及びフラットハーネス５０の端末部が装着される支持部材としてのコネクタハウジング２とを備えて構成されている。   As shown in FIG. 1, the flat harness connector 1 includes a flat harness 50, a plurality of connection terminals 40 connected to a terminal portion of the flat harness 50, a plurality of connection terminals 40 and a terminal portion of the flat harness 50. And a connector housing 2 as a support member to which is mounted.

フラットハーネス５０は、この例では絶縁フィルムなどの平面状絶縁体５３の上に平面状の複数の導体５１をパターン形成して所定の回路部を形成し、これらの上にカバーレイフィルムなどの絶縁被覆５２を形成したいわゆるフレキシブルプリント基板（ＦＰＣ）からなり、例えばその端末部において厚さ方向の一方の面側の絶縁被覆５２が除去されて、並設された各導体５１がそれぞれ露出された構造からなるものである。   In this example, the flat harness 50 is formed by patterning a plurality of planar conductors 51 on a planar insulator 53 such as an insulating film to form a predetermined circuit portion, and insulating a coverlay film or the like thereon. A structure comprising a so-called flexible printed circuit board (FPC) having a coating 52 formed thereon, for example, the insulating coating 52 on one surface side in the thickness direction is removed at the terminal portion, and the respective conductors 51 arranged in parallel are exposed. It consists of

その他にもフラットハーネス５０としては、図示は省略するが例えば複数の矩形断面形状の導体５１の押出成形により所定の回路部を形成してこの回路部を絶縁フィルムなどの絶縁被覆５２でラミネートしたいわゆるフレキシブルフラットケーブル（ＦＦＣ）などを用いることができる。   In addition, the flat harness 50 is a so-called flat harness 50, which is not illustrated, for example, a predetermined circuit portion is formed by extrusion molding of a plurality of conductors 51 having a rectangular cross-sectional shape, and this circuit portion is laminated with an insulating coating 52 such as an insulating film. A flexible flat cable (FFC) or the like can be used.

フラットハーネス５０の各導体５１とそれぞれ接続される複数の接続端子４０は、例えば図３に示すように、先端側に形成されて図示しない相手方接続端子と接続可能な端子接続部４１と、基端側に形成されてフラットハーネス５０の各導体５１と接続される導体接続部４２とを備えて構成され、この例では全体が板状に形成されている。   The plurality of connection terminals 40 respectively connected to the respective conductors 51 of the flat harness 50 include, as shown in FIG. 3, for example, a terminal connection portion 41 that is formed on the distal end side and can be connected to a counterpart connection terminal (not shown), The conductor connection part 42 formed in the side and connected with each conductor 51 of the flat harness 50 is comprised, and the whole is formed in plate shape in this example.

コネクタハウジング２は樹脂成型部材からなり、複数の接続端子４０が装着される子ハウジング１０と、この子ハウジング１０を内部に収容する親ハウジング２０と、この親ハウジング２０に収容された子ハウジング１０を親ハウジング２０に係止固定するロック部材３０とを備えて構成されている。   The connector housing 2 is made of a resin molded member, and includes a child housing 10 in which a plurality of connection terminals 40 are mounted, a parent housing 20 that houses the child housing 10, and a child housing 10 that is housed in the parent housing 20. And a lock member 30 that is locked and fixed to the parent housing 20.

子ハウジング１０は、複数の接続端子４０を、その端子接続部４１と導体接続部４２とをそれぞれ先端側及び基端側に露出させた状態で保持するもので、複数の接続端子４０を複数の端子圧入孔１１に圧入して保持するか一体成形により保持する。子ハウジング１０には、導体接続部４２が突出した側に、導線接続部４２の下面側とわずかの隙間を空けて対向する板状の端子支持部（第１の端子支持部）１２が形成されている。上記の隙間は、ほぼフラットハーネス５０の端末部の厚みに相当する。従って、図３に示すように、端子支持部１２は、複数の接続端子４０の導体接続部４２とフラットハーネス５０の端末部の導体５１との接合部５４を、フラットハーネス５０側から支持するものとなっている。   The sub-housing 10 holds the plurality of connection terminals 40 in a state where the terminal connection portions 41 and the conductor connection portions 42 are exposed at the distal end side and the proximal end side, respectively. The terminal is press-fitted into the terminal press-fitting hole 11 or is held by integral molding. The child housing 10 is formed with a plate-like terminal support portion (first terminal support portion) 12 facing the lower surface side of the conductor connection portion 42 with a slight gap on the side where the conductor connection portion 42 protrudes. ing. The above gap substantially corresponds to the thickness of the terminal portion of the flat harness 50. Therefore, as shown in FIG. 3, the terminal support part 12 supports the joining part 54 of the conductor connection part 42 of the some connection terminal 40 and the conductor 51 of the terminal part of the flat harness 50 from the flat harness 50 side. It has become.

各接続端子４０の導体接続部４２とフラットハーネス５０の端末部の導体５１とは、例えば抵抗溶接（シリーズ溶接）により接合部５４において接合されている。即ち、フラットハーネス５０の端末部を、接続端子４０の基端側から上記隙間に挿入したのち、例えば図４に示すように、導体接続部４２の上方から一対の電極６１，６２を導体接続部４２に当接させ、加圧しながら各電極６１，６２間に所定の電流を所定時間通電させて導体接続部４２と導体５１との接触部分である接合部５４の金属を溶解し、両者を接合するようにしている。なお、図面上では便宜的に接合部５４をスポット状に描画しているが、実際には接合部５４は各電極６１，６２の直下周辺から両電極６１，６２間にわたって形成されるものである。   The conductor connection part 42 of each connection terminal 40 and the conductor 51 of the terminal part of the flat harness 50 are joined at the joint part 54 by, for example, resistance welding (series welding). That is, after the terminal portion of the flat harness 50 is inserted into the gap from the base end side of the connection terminal 40, the pair of electrodes 61 and 62 are connected to the conductor connection portion from above the conductor connection portion 42, for example, as shown in FIG. 42, a predetermined current is passed between the electrodes 61 and 62 for a predetermined time while applying pressure to melt the metal of the joint portion 54, which is a contact portion between the conductor connection portion 42 and the conductor 51, and join them together. Like to do. In the drawing, the joint portion 54 is drawn in a spot shape for convenience, but in reality, the joint portion 54 is formed from the periphery immediately below the electrodes 61 and 62 to between the electrodes 61 and 62. .

導体接続部４２と導体５１とは、このようなシリーズ溶接などの抵抗溶接の他にも、例えば超音波溶着、レーザ溶接、アーク溶接、半田付け及びピアッシングの少なくとも１つによって接合されていても良い。   In addition to resistance welding such as series welding, the conductor connecting portion 42 and the conductor 51 may be joined by at least one of ultrasonic welding, laser welding, arc welding, soldering, and piercing, for example. .

一方、子ハウジング１０と共にコネクタハウジング２を構成する親ハウジング２０は、図３に示すように、基端側に形成されて内部に子ハウジング１０を収容する子ハウジング収容室２１が形成された基端側ハウジング２３と、先端側に形成されて子ハウジング収容室２１に収容された子ハウジング１０から突出する接続端子４０の端子接続部４１が収容されると共に図示しない相手方コネクタハウジングと嵌合する嵌合部２２が内部に形成された先端側ハウジング２４とを樹脂により一体形成したものである。基端側ハウジング２４の図中上方の側壁には開口部２８が形成されている。   On the other hand, as shown in FIG. 3, the parent housing 20 that constitutes the connector housing 2 together with the child housing 10 is formed on the proximal end side, and the proximal end in which the child housing accommodation chamber 21 for accommodating the child housing 10 is formed. The side housing 23 and the terminal connection portion 41 of the connection terminal 40 that is formed on the distal end side and protrudes from the child housing 10 housed in the child housing housing chamber 21 are accommodated and fitted into a mating connector housing (not shown). A distal end side housing 24 having a portion 22 formed therein is integrally formed of resin. An opening 28 is formed in the upper side wall of the base end side housing 24 in the drawing.

親ハウジング２０の開口部２８には、ロック部材３０が挿入されている。このロック部材３０は、第２の端末支持部材として機能するもので、図３に示すように、子ハウジング収容室２１内に完全収容された子ハウジング１０の端末支持部１２に支持されたフラットハーネス５０の端末部を、端末支持部１２と共に挟み込んだ状態で固定すると共に子ハウジング１０を親ハウジング２０に係止固定する機能を有する。ロック部材３０の側面３９ａ３９ｂには、完全挿入時の開口部２８からの離脱を防止するための係止突起３８が形成されている。また、ロック部材３０の挿入方向の先端面には、開口部２８への完全挿入時に接続端子４０の導体接続部４２が嵌る溝部３１が形成されている。ロック部材３０は、溝部３１の底面で導体接続部４２の上面と基端の縁を押さえると共に、溝部３１の底面から先端側に一段高くなった固定面３２でフラットハーネス５０の端末部をその厚さ方向に押さえる。したがって、フラットハーネス５０の端末部の導体５１と接続端子４０の導体接続部４２との接合部５４は、端末支持部材１２とロック部材４０とで上下から挟持され、接合部５４に引き剥がし方向の力が加わるのを防止することができる。   A lock member 30 is inserted into the opening 28 of the parent housing 20. The lock member 30 functions as a second terminal support member. As shown in FIG. 3, the flat harness supported by the terminal support portion 12 of the child housing 10 fully accommodated in the child housing accommodation chamber 21 as shown in FIG. 3. 50 terminal portions are fixed in a state of being sandwiched together with the terminal support portion 12 and have a function of locking and fixing the child housing 10 to the parent housing 20. Locking projections 38 are formed on the side surfaces 39a39b of the lock member 30 to prevent the lock member 30 from being detached from the opening 28 during complete insertion. Further, a groove portion 31 into which the conductor connection portion 42 of the connection terminal 40 is fitted when the lock member 30 is inserted completely into the opening portion 28 is formed on the distal end surface in the insertion direction. The lock member 30 presses the upper surface and the base edge of the conductor connection portion 42 on the bottom surface of the groove portion 31, and the thickness of the end portion of the flat harness 50 on the fixed surface 32 that is raised from the bottom surface of the groove portion 31 to the distal end side. Hold in the direction. Therefore, the joint portion 54 between the conductor 51 of the terminal portion of the flat harness 50 and the conductor connection portion 42 of the connection terminal 40 is sandwiched from above and below by the terminal support member 12 and the lock member 40 and is peeled off from the joint portion 54 in the peeling direction. It is possible to prevent force from being applied.

ロック部材３０は、図５（ａ），（ｂ）に示すように、子ハウジング１０を親ハウジング２０に挿入した後に、接合部５４側に押し込まれる。これにより、図５（ｃ）のように、ロック部材３０が導体接続部４２の上面と基端縁部とをしっかりと押さえて固定する。もし、図６に示すように、子ハウジング１０が親ハウジング２０内に完全に収容されていない場合には、ロック部材３０の固定面３２が接続端子４０の導体接続部４２と干渉するため、接続端子４０の導体接続部４２が溝部３１に入らず、ロック部材３０を開口部２８に完全挿入することができない。このため、組み立て不良を事前に発見することができる。   As shown in FIGS. 5A and 5B, the lock member 30 is pushed into the joint portion 54 side after the child housing 10 is inserted into the parent housing 20. Thereby, as shown in FIG. 5C, the lock member 30 firmly presses and fixes the upper surface and the base end edge portion of the conductor connection portion 42. If the child housing 10 is not completely accommodated in the parent housing 20 as shown in FIG. 6, the fixing surface 32 of the lock member 30 interferes with the conductor connection portion 42 of the connection terminal 40. The conductor connecting portion 42 of the terminal 40 does not enter the groove portion 31, and the lock member 30 cannot be completely inserted into the opening portion 28. For this reason, a defective assembly can be found in advance.

なお、ロック部材３０の固定面３２及び端末支持部１２の固定面３２と対向する面の少なくとも一方に突起や突条を形成すれば、ロック部材３０の開口部２８への完全挿入時に更に強固にフラットハーネス５０の端末部を挟み込んで固定することが可能となる。   In addition, if protrusions or protrusions are formed on at least one of the fixed surface 32 of the lock member 30 and the surface facing the fixed surface 32 of the terminal support portion 12, the lock member 30 can be more firmly inserted when completely inserted into the opening 28. The terminal portion of the flat harness 50 can be sandwiched and fixed.
