Description

本発明は、ＦＰＣなどの接続に用いられる端子部材、該端子金具を備えたコネクタ、及び、該端子部材接続方法に関するものである。 The present invention relates to a terminal member used for connecting an FPC, a connector provided with the terminal fitting, and a method of connecting the terminal member.

小型の電子機器モジュールには、それが備える各部品間などを電気的に接続する電線として、屈曲自在な可撓性を有するフレキシブルプリント基板（ＦｌｅｘｉｂｌｅＰｒｉｎｔｅｄＣｉｒｃｕｉｔ、以下、「ＦＰＣ」という）が用いられる。ＦＰＣは、ポリイミド等の合成樹脂からなる絶縁フィルム間に、配線パターンとしての銅などからなる線状の導体（即ち、芯線）を挟み込んで構成されている。また、ＦＰＣの端部の一部には、導体を挟む一方のフィルムが除去されて導体がむき出しにされた端子部が形成されており、該ＦＰＣの端子部が形成された面とは反対側の面に、この端子部を支えるように上記フィルムより硬質で平板状に形成された合成樹脂板が設けられ、これら端子部と合成樹脂板とでＦＰＣの電気接触部を構成している。ＦＰＣは、例えば、特許文献１に示されるようなコネクタが実装された印刷配線板間の接続に用いられたり、小型の電子機器モジュールの内部配線に用いられたりする。 In a small electronic device module, a flexible printed circuit board (Flexible Printed Circuit, hereinafter referred to as “FPC”) is used as an electric wire for electrically connecting components included in the module. . The FPC is configured by sandwiching a linear conductor (that is, a core wire) made of copper or the like as a wiring pattern between insulating films made of a synthetic resin such as polyimide. In addition, a terminal portion in which one of the films sandwiching the conductor is removed to expose the conductor is formed on a part of the end portion of the FPC, and the side opposite to the surface on which the terminal portion of the FPC is formed. A synthetic resin plate that is harder than the film and formed in a flat plate shape is provided to support the terminal portion, and the terminal portion and the synthetic resin plate constitute an electrical contact portion of the FPC. The FPC is used, for example, for connection between printed wiring boards on which connectors as shown in Patent Document 1 are mounted, or used for internal wiring of a small electronic device module.

このようなＦＰＣを備える電子機器モジュールを、図９に示す。この電子機器モジュール７０１は、アッパケース７０８と、アッパケース７０８と組み合わされるとともに図１０に示すワイヤハーネス８０３が備えるコネクタ８０４と嵌合するコネクタ部７１８を備えたロアケース７０９と、アッパケース７０８に収容されるカメラユニット７１０と、カメラユニット７１０を上述したコネクタ８０４に電気的に接続するＦＰＣ７３４を備えた接続ユニット７１１と、を有している。 An electronic device module including such an FPC is shown in FIG. The electronic device module 701 is accommodated in an upper case 708, a lower case 709 that is combined with the upper case 708 and includes a connector portion 718 that fits into a connector 804 included in the wire harness 803 shown in FIG. And a connection unit 711 including an FPC 734 that electrically connects the camera unit 710 to the connector 804 described above.

ＦＰＣ７３４は、その一端部７３４ａが接続ユニット７１１を構成する一対の印刷配線板７３５に挟まれており、一方の印刷配線板７３５の表面に実装されたコネクタ７３３に電気的に接続されている。このコネクタ７３３はカメラユニット７１０が備えるコネクタ７２７に接続されている。ＦＰＣ７３４の他端部７３４ｂは、絶縁フィルムの一部を除去し、導体を露出させて形成した端子部７３４ｄが設けられている。また、この端子部７３４ｄを支持するための合成樹脂板７３４ｅが、端子部７３４ｄの導体が露出された面とは反対側の面に接着剤などで固着されており、端子部７３４ｄと合成樹脂板７３４ｅとでＦＰＣ７３４の電気接触部７３４１を構成している。ＦＰＣ７３４の他端部７３４ｂは、ロアケース７０９に設けられた貫通孔に挿通され、コネクタ部７１８に設けられた立設板部７２１の一方の表面に密に重ねられて固定されている。ＦＰＣ７３４は薄く且つ可撓性を有しているので、電子機器モジュール内の極小空間を引き回すことができ、そのため、カメラユニット７１０が備えるコネクタ７２７の端子を、ＦＰＣ７３４を介して、電子機器モジュール７０１の外部に引き出すことができた。 One end portion 734 a of the FPC 734 is sandwiched between a pair of printed wiring boards 735 constituting the connection unit 711, and is electrically connected to a connector 733 mounted on the surface of one printed wiring board 735. This connector 733 is connected to a connector 727 provided in the camera unit 710. The other end portion 734b of the FPC 734 is provided with a terminal portion 734d formed by removing a part of the insulating film and exposing the conductor. Further, a synthetic resin plate 734e for supporting the terminal portion 734d is fixed to the surface of the terminal portion 734d opposite to the surface where the conductor is exposed with an adhesive or the like, and the terminal portion 734d and the synthetic resin plate are fixed. 734e forms an electrical contact portion 7341 of the FPC 734. The other end portion 734 b of the FPC 734 is inserted into a through hole provided in the lower case 709, and is closely overlapped and fixed on one surface of the standing plate portion 721 provided in the connector portion 718. Since the FPC 734 is thin and flexible, a minimal space in the electronic device module can be drawn. Therefore, the terminal of the connector 727 included in the camera unit 710 is connected to the electronic device module 701 via the FPC 734. I was able to pull it out.

図１０に示すように、電子機器モジュール７０１と接続されるワイヤハーネス８０３が備えるコネクタ８０４は、ケーブル８１０が備える被覆導線８１６の絶縁被覆８１５が剥かれて露出された芯線８１４に電気的に接続された端子金具８５０と、端子金具８５０を収容して支持する絶縁性のインナハウジング８２０と、インナハウジング８２０の外周に密に重ねられる導電性のシールドシェル８３０と、シールドシェル８３０の外周に密に重ねられる絶縁性のアウタハウジング８６０と、を備えており、ケーブル８１０の端末に取り付けられている。 As shown in FIG. 10, the connector 804 included in the wire harness 803 connected to the electronic device module 701 is electrically connected to the core wire 814 exposed by peeling off the insulating coating 815 of the coated conductor 816 included in the cable 810. Terminal fitting 850, an insulating inner housing 820 that accommodates and supports the terminal fitting 850, a conductive shield shell 830 that is densely stacked on the outer periphery of the inner housing 820, and a dense overlap on the outer periphery of the shield shell 830. And an insulating outer housing 860 that is attached to the end of the cable 810.

図１０に示すように、電子機器モジュール７０１のコネクタ部７１８とコネクタ８０４とが嵌合すると、ＦＰＣ７３４に設けられた電気接触部７３４１の端子部７３４ｄと、コネクタ８０４の端子金具８５０とが接触して、電子機器モジュール７０１に備えられたカメラユニット７１０と、ケーブル８１０の先に接続された図示しない装置等とを電気的に接続することができた。
特開２００８−５２９９２号公報 As shown in FIG. 10, when the connector portion 718 of the electronic device module 701 and the connector 804 are fitted, the terminal portion 734d of the electrical contact portion 7341 provided in the FPC 734 and the terminal fitting 850 of the connector 804 come into contact with each other. The camera unit 710 provided in the electronic device module 701 can be electrically connected to a device (not shown) connected to the end of the cable 810.

しかしながら、ＦＰＣ７３４の電気接触部７３４１は、端子部７３４ｄを合成樹脂板７３４ｅで支持しており、この合成樹脂板７３４ｅは通常端子金具８５０より柔らかいので、端子部７３４ｄに端子金具８５０が接触した状態で長時間経過すると、端子部７３４ｄと端子金具８５０との間の接圧によって合成樹脂板７３４ｅが陥没変形してしまい、該接圧が低下して接触不良が生じてしまうという問題があった。また、合成樹脂板を有していないＦＰＣにおいても、ＦＰＣ自体（即ち、導体及び絶縁フィルム）が柔らかいので同様の問題があった。また、この問題を回避するため、端子部７３４ｄと端子金具８５０との間の接圧を予め高く設定しておくことが考えられるが、ワイヤハーネス８０３のコネクタ８０４が複数の端子金具８５０を備えている場合、コネクタ嵌合（挿入）に大きな力が必要となってしまい、組立性が悪化するという別の問題があった。 However, the electrical contact portion 7341 of the FPC 734 supports the terminal portion 734d with a synthetic resin plate 734e, and this synthetic resin plate 734e is usually softer than the terminal fitting 850, so that the terminal fitting 850 is in contact with the terminal portion 734d. When a long time elapses, the synthetic resin plate 734e is depressed and deformed by the contact pressure between the terminal portion 734d and the terminal fitting 850, and there is a problem in that the contact pressure is lowered and contact failure occurs. Further, even in an FPC that does not have a synthetic resin plate, the FPC itself (that is, a conductor and an insulating film) has a similar problem because it is soft. In order to avoid this problem, it is conceivable that the contact pressure between the terminal portion 734d and the terminal fitting 850 is set high in advance. However, the connector 804 of the wire harness 803 includes a plurality of terminal fittings 850. In such a case, a large force is required for connector fitting (insertion), which causes another problem that the assemblability deteriorates.

本発明は、上記課題に係る問題を解決することを目的としている。即ち、本発明は、組立性を悪化させることなく接触不良を防止できる端子部材、コネクタ、及び、端子部材接続方法を提供することを目的としている。 The present invention aims to solve the above problems.

請求項１、３、４に記載された発明によれば、端子部材が有する一対のアーム部の他方の端部間の隙間が、それに挿入される電線の電気接触部の厚みと同じに形成されており、一対のアーム部の一方の端部間の隙間が、それに挿入される被狭持部材の厚みより小さく形成されているので、電線の電気接触部を他方の端部間の隙間に容易に挿入することができるとともに、被狭持部材を一方の端部間の隙間に挿入すると一方の端部間の隙間が広がることにより他方の端部間の隙間が狭まり、他方の端部間の隙間に挿入された電線の電気接触部を強く挟み込んで接圧を高めることができる。そのため、組立性を向上できるとともに接触不良を防止できる。 According to the first, third, and fourth aspects of the present invention, the gap between the other ends of the pair of arm portions of the terminal member is formed to be the same as the thickness of the electrical contact portion of the electric wire inserted therein. Since the gap between one end of the pair of arm portions is smaller than the thickness of the sandwiched member inserted into the arm portion, the electric contact portion of the electric wire can be easily placed in the gap between the other end portions. Can be inserted into the gap between the two ends, and the gap between the one ends widens when the member to be held is inserted into the gap between the other ends, thereby narrowing the gap between the other ends.

Because of the lever principle, the force to widen the gap between one end can be reduced and the force to narrow the gap between the other end can be increased by the lever principle. It can improve more and can prevent poor contact more.

以下、本発明に係る端子部材および該端子部材を備えた電子機器モジュールの一実施形態を、図１〜図８を参照して説明する。まず、端子部材について説明する。 Hereinafter, an embodiment of a terminal member and an electronic device module including the terminal member according to the present invention will be described with reference to FIGS. First, the terminal member will be described.

図５〜図７に示される端子部材７０は、導線性の板金を所定の形に打ち抜くなどして形成されている。端子部材７０は、図５などに示すように、互いに隙間を空けて平行に配された一対のアーム部７１と、一対のアーム部７１と一体に形成され且つ一対のアーム部７１の中央部分を互いに接続する支点部７２と、を備えている。なお、本発明において「平行」とは、厳密に平行の場合とほぼ平行の場合との両方を含む。 The terminal member 70 shown in FIGS. 5 to 7 is formed by punching a conductive sheet metal into a predetermined shape. As shown in FIG. 5 and the like, the terminal member 70 is formed integrally with a pair of arm portions 71 and a pair of arm portions 71 that are arranged in parallel with a gap between each other, and a central portion of the pair of arm portions 71. And a fulcrum part 72 connected to each other. In the present invention, “parallel” includes both strictly parallel and almost parallel.

Is formed. In addition, an electrical contact portion 341 provided at the other end portion 34b of the FPC 34 described later is inserted into the gap D2 between the other end portions 70b of the terminal member 70, and a gap between the one end portions 70a of the terminal member 70 is inserted. A terminal member mounting portion 21 (that is, a pinched member in the claims) provided integrally with the lower case 9 of the electronic device module 1 described later is inserted into D1.

端子部材７０の他方の端部７０ｂ間の隙間Ｄ２は、ＦＰＣ３４の電気接触部３４１の厚みと同じに形成されている。端子部材７０の一方の端部７０ａ間の隙間Ｄ１は、ロアケース９の端子部材取付部２１の厚みより小さく形成されている。なお、本発明において「同じ」とは、厳密に同じ場合とほぼ同じ場合との両方を含む。 A gap D <b> 2 between the other end portions 70 b of the terminal member 70 is formed to have the same thickness as the electrical contact portion 341 of the FPC 34.

In the present invention, “same” includes both exactly the same case and almost the same case.

また、端子部材７０の一方の端部７０ａの先端７０ｃから支点部７２までの長さＬ１が、端子部材７０の他方の端部７０ｂの先端７０ｄから支点部７２までの長さＬ２より、長くなるように形成されている。 In addition, the length L1 from the tip 70c of one end 70a of the terminal member 70 to the fulcrum 72 is longer than the length L2 from the tip 70d of the other end 70b of the terminal member 70 to the fulcrum 72. It is formed as follows.

端子部材７０の一方の端部７０ａには間隔をあけて相対する一対の爪７０ｅが、一方の端部７０ａの先端部分及び中央部分に設けられている。これら一対の爪７０は、端子部材７０の一方の端部７０ａ間の隙間Ｄ１に挿入された端子部材取付部２１に係合してそれを固定する。また、端子部材７０の他方の端部７０ｂには間隔をあけて相対する一対の爪７０ｆが、他方の端部７０ｂの先端部分に設けられている。これら一対の爪７０ｆは、端子部材７０の他方の端部７０ｂ間の隙間Ｄ２に挿入されたＦＰＣ３４の電気接触部７３４１に係合してそれを固定するとともに、接圧を高めて接触抵抗を低下させる。 A pair of claws 70e facing each other with a gap is provided at one end portion 70a of the terminal member 70 at the front end portion and the central portion of the one end portion 70a. The pair of claws 70 engage with and fix the terminal member mounting portion 21 inserted in the gap D1 between the one end portions 70a of the terminal member 70. In addition, a pair of claws 70f facing the other end portion 70b of the terminal member 70 with a space therebetween are provided at the distal end portion of the other end portion 70b. The pair of claws 70f engage and fix the electrical contact portion 7341 of the FPC 34 inserted in the gap D2 between the other end portions 70b of the terminal member 70, and increase the contact pressure to reduce the contact resistance. Let

本実施形態においては、例えば、端子部材７０の一方の端部７０ａ間の隙間Ｄ１が０．５０ｍｍ、他方の端部７０ｂ間の隙間Ｄ２が０．５１ｍｍ、一方の端部７０ａの先端７０ｃから支点部７２までの長さＬ１が４．００ｍｍ、他方の端部７０ｂの先端７０ｄから支点部７２までの長さＬ２が２．４０ｍｍ、厚みＴが０．２０ｍｍ、に形成されている。また、後述するＦＰＣ３４の電気接触部３４１の厚みが０．５０ｍｍ、後述するロアケース９の端子部材取付部２１の厚みが０．７０ｍｍ、にそれぞれ形成されている。 In the present embodiment, for example, the gap D1 between the one end portions 70a of the terminal member 70 is 0.50 mm, the gap D2 between the other end portions 70b is 0.51 mm, and the fulcrum from the tip 70c of the one end portion 70a. The length L1 to the portion 72 is 4.00 mm, the length L2 from the tip 70d of the other end portion 70b to the fulcrum portion 72 is 2.40 mm, and the thickness T is 0.20 mm. Moreover, the thickness of the electric contact part 341 of the FPC 34 to be described later is formed to 0.50 mm, and the thickness of the terminal member mounting part 21 of the lower case 9 to be described later is 0.70 mm.

このような端子部材７０は、その他方の端部７０ｂ間の隙間Ｄ２に、ＦＰＣ３４の電気接触部３４１を挿入したのち、その一方の端部７０ａ間の隙間Ｄ１に、ロアケース９の端子部材取付部２１を挿入することにより、隙間Ｄ１が広がるとともに支点部７２を支点として隙間Ｄ２が狭まり、端子部材７０をロアケース９に固定するとともに、端子部材７０によってＦＰＣ３４の電気接触部３４１を強く挟み込むことができる。そのため、ＦＰＣ３４と端子部材７０との間の接圧を高めることができる。 In such a terminal member 70, after inserting the electric contact portion 341 of the FPC 34 into the gap D2 between the other end portions 70b, the terminal member mounting portion of the lower case 9 is inserted into the gap D1 between the one end portions 70a. 21, the gap D1 is widened and the gap D2 is narrowed with the fulcrum part 72 as a fulcrum, so that the terminal member 70 can be fixed to the lower case 9 and the electric contact part 341 of the FPC 34 can be strongly sandwiched by the terminal member 70. . Therefore, the contact pressure between the FPC 34 and the terminal member 70 can be increased.

この端子部材７０は、図２、図３に示す、絶縁性の合成樹脂で形成された支持部材８０によって支持されている。支持部材８０は、複数の端子部材７０それぞれの他方の端部７０ｂをその内側に収容して支持する。支持部材８０は、角筒状の本体部８１と、本体部８１の一端部８０ａに設けられたフランジ部８２と、で構成されている。本体部８１の内側には、図３に示すように、相対する一対の内面間にわたされた棒状の支持部８３が、一端部８０ａ寄りの箇所に設けられている。 The terminal member 70 is supported by a support member 80 formed of an insulating synthetic resin as shown in FIGS. The support member 80 accommodates and supports the other end 70b of each of the plurality of terminal members 70 inside thereof. The support member 80 includes a rectangular tube-shaped main body portion 81 and a flange portion 82 provided at one end portion 80 a of the main body portion 81. As shown in FIG. 3, a rod-like support portion 83 provided between a pair of opposed inner surfaces is provided inside the main body portion 81 at a location near the one end portion 80 a.

さらに、ＦＰＣ３４は、それ自身が可撓性を有しているので、一端部３４ａと他端部３４ｂとの間の中央部３４ｃが、変形自在な変形部をなしている。 Further, since the FPC 34 itself has flexibility, the central portion 34c between the one end portion 34a and the other end portion 34b forms a deformable deformable portion.

取付部１２は、図４に示すように、ロアケース９の底壁１６から立設したボス部３６と、基板３２に設けられた貫通孔３７とを備えている。ボス部３６は、底壁１６から立設した円柱状の挟持部３８と、この挟持部３８から立設した一対の小径部３９と、当該小径部３９の先端に連なった一対の係止爪部４０とを一体に備えている。 As shown in FIG. 4, the attachment portion 12 includes a boss portion 36 erected from the bottom wall 16 of the lower case 9 and a through hole 37 provided in the substrate 32. The boss portion 36 includes a cylindrical pinching portion 38 erected from the bottom wall 16, a pair of small diameter portions 39 erected from the pinching portion 38, and a pair of latching claw portions continuous to the tip of the small diameter portion 39. 40 as a single unit.

小径部３９は、互いに間隔をあけかつ平行に配置されている。小径部３９は、貫通孔３７内に通される。小径部３９は、貫通孔３７内に通されると、当該その外周面が貫通孔３７の内面と間隔をあける。このため、小径部３９は、挟持部３８と係止爪部４０との間に設けられかつ貫通孔３７よりも小さく形成されてこの貫通孔３７の内面と間隔をあける。係止爪部４０は、小径部３９即ちボス部３６の先端に設けられて、貫通孔３７内に通されて基板３２のコネクタ３３が設けられた印刷配線板３５の表面に密に係止する。貫通孔３７は、基板３２を貫通しかつその内径が小径部３９の外径よりも大きく形成されている。 The small diameter portions 39 are arranged in parallel and spaced apart from each other. The small diameter portion 39 is passed through the through hole 37. When the small diameter portion 39 is passed through the through hole 37, the outer peripheral surface thereof is spaced from the inner surface of the through hole 37. For this reason, the small-diameter portion 39 is provided between the clamping portion 38 and the locking claw portion 40 and is formed smaller than the through-hole 37 and is spaced from the inner surface of the through-hole 37. The locking claw portion 40 is provided at the tip of the small diameter portion 39, that is, the boss portion 36, and is passed through the through hole 37 to closely lock the surface of the printed wiring board 35 provided with the connector 33 of the substrate 32. . The through hole 37 penetrates the substrate 32 and has an inner diameter larger than the outer diameter of the small diameter portion 39.

前述した取付部１２は、貫通孔３７内に係止爪部４０からボス部３６が圧入される。すると、一対の係止爪部４０が互いに近づく方向に小径部３９が一旦弾性変形した後、係止爪部４０が貫通孔３７内を通ると、小径部３９の弾性復元力により、係止爪部４０が基板３２の印刷配線板３５の表面に密に重なるとともに、ボス部３６の挟持部３８上に基板３２が密に接触して重なる。こうして、係止爪部４０と、ボス部３６との間に基板３２を挟みこむ。すると、取付部１２は、小径部３９が貫通孔３７の内面と間隔をあける。こうして、取付部１２は、ロアケース９に接続ユニット１１の基板３２を取り付ける。 In the mounting portion 12 described above, the boss portion 36 is press-fitted into the through hole 37 from the locking claw portion 40. Then, after the small diameter portion 39 is once elastically deformed in the direction in which the pair of locking claws 40 approach each other, when the locking claw portion 40 passes through the through hole 37, the locking claw is caused by the elastic restoring force of the small diameter portion 39. The portion 40 closely overlaps the surface of the printed wiring board 35 of the substrate 32, and the substrate 32 closely contacts and overlaps the sandwiching portion 38 of the boss portion 36. In this way, the substrate 32 is sandwiched between the locking claw portion 40 and the boss portion 36. As a result, the small diameter portion 39 of the attachment portion 12 is spaced from the inner surface of the through hole 37. Thus, the attachment portion 12 attaches the substrate 32 of the connection unit 11 to the lower case 9.

取付部１２は、ボス部３６と係止爪部４０とが基板３２に密に接触するので、基板３２が当該基板３２の厚み方向に沿ってロアケース９に対して移動することを規制する。また、取付部１２は、小径部３９が貫通孔３７の内面と間隔をあけるので、基板３２が当該基板３２の表面に沿ってロアケース９に対して移動することを許容する。このように、取付部１２は、ボス部３６と貫通孔３７とを備えているので、ロアケース９と基板３２とに亘って設けられて、基板３２をロアケース９に取り付けている。 Since the boss portion 36 and the locking claw portion 40 are in close contact with the substrate 32, the attachment portion 12 restricts the substrate 32 from moving with respect to the lower case 9 along the thickness direction of the substrate 32. Further, the mounting portion 12 allows the substrate 32 to move relative to the lower case 9 along the surface of the substrate 32 because the small diameter portion 39 is spaced from the inner surface of the through hole 37. As described above, since the attachment portion 12 includes the boss portion 36 and the through hole 37, the attachment portion 12 is provided across the lower case 9 and the substrate 32, and attaches the substrate 32 to the lower case 9.

また、前述した電子機器モジュール１は、ロアケース９内に液状の状態で充填されて硬化したポッティング剤４１が充填されている。ポッティング剤４１は、例えば、シリコーンで構成されている。そして、このシリコーンは、揺変性を有した室温硬化型シリコーンゴムであるのが好ましい。ここでいう揺変性とは、硬化前のシリコーンゴムが、一定以上の振動等を加えると液体状態（流動性が高い状態）となり、静置状態では固体状態（前記液体状態よりも流動性が低い状態）となる性質のことである。 Further, the electronic device module 1 described above is filled with the potting agent 41 filled and cured in a liquid state in the lower case 9. The potting agent 41 is made of, for example, silicone. The silicone is preferably a room temperature curable silicone rubber having thixotropy. The thixotropy referred to herein is a liquid state (high fluidity state) when the silicone rubber before curing is subjected to a certain level of vibration or the like, and a solid state (lower fluidity than the liquid state) in the stationary state. State).

ポッティング剤４１が揺変性であることによって、液体状態で止水すべき部位に確実に入り込み、前記部位に入り込んだまま固体状態となって当該部位に留まるので、前記部位を確実に水密に保つことができる。また、ポッティング剤４１が室温硬化型であることによって、ポッティング剤４１を硬化させるために加熱する必要がなくなって製造工程が簡素化され、また加熱装置が必要なくなって製造設備の増加を防止できる。ポッティング剤４１は、孔６２及び窪み部６１を通してアッパケース８及びロアケース９内に液体が浸入することを規制する。 Since the potting agent 41 is thixotropic, it surely enters the part that should be stopped in the liquid state, and remains in the part in a solid state while entering the part, so that the part is surely kept watertight. Can do. Moreover, since the potting agent 41 is a room temperature curing type, it is not necessary to heat the potting agent 41 to cure it, the manufacturing process is simplified, and a heating device is not necessary, thereby preventing an increase in manufacturing facilities. The potting agent 41 restricts liquid from entering the upper case 8 and the lower case 9 through the hole 62 and the recess 61.

さらに、電子機器モジュール１は、ロアケース９の底壁１６に重ねられる平板状の導電性のグランドシェル４３を備えている。 Furthermore, the electronic device module 1 includes a flat conductive ground shell 43 that is stacked on the bottom wall 16 of the lower case 9.

次に、前述した構成の電子機器モジュール１の組み立てについて説明する。まず、支持部材８０の内側に端子部材７０を挿入してそれらを互いに組み付ける。そして、カメラユニット１０をアッパケース８に取り付ける。 Next, assembly of the electronic device module 1 having the above-described configuration will be described. First, the terminal member 70 is inserted inside the support member 80 and assembled to each other. Then, the camera unit 10 is attached to the upper case 8.

そして、ＦＰＣ３４の電気接触部３４１を支持部材８０の他端部８０ｂに挿入して、ＦＰＣ３４の電気接触部３４１を支持部材８０に収容されている端子部材７０の他方の端部７０ｂ間の隙間Ｄ２内に位置づける。そして、支持部材８０にＦＰＣ３４の電気接触部３４１を挿入したまま、支持部材８０をロアケース９の窪み部６１に挿入して、端子部材７０の一方の端部７０ａ間に端子部材取付部２１を挟み込む。これにより、端子部材７０が、ロアケース９に固定されるとともに、端子部材７０の他方の端部７０ｂ間の隙間Ｄ２内に位置づけられたＦＰＣ３４の電気接触部３４１を挟み込む。 Then, the electrical contact portion 341 of the FPC 34 is inserted into the other end portion 80b of the support member 80, and the gap D2 between the other end portions 70b of the terminal member 70 accommodated in the support member 80 is inserted into the electrical contact portion 341 of the FPC 34. Position within. Then, with the electrical contact portion 341 of the FPC 34 inserted into the support member 80, the support member 80 is inserted into the recessed portion 61 of the lower case 9, and the terminal member attachment portion 21 is sandwiched between one end portion 70 a of the terminal member 70. . As a result, the terminal member 70 is fixed to the lower case 9, and the electric contact portion 341 of the FPC 34 positioned in the gap D2 between the other end portions 70b of the terminal member 70 is sandwiched.

そして、取付部１２によりロアケース９に基板３２を取り付ける。その後、ロアケース９内に液状のポッティング剤４１を充填して、当該ポッティング剤４１を硬化させる。こうして、ロアケース９に接続ユニット１１を取り付ける。 Then, the substrate 32 is attached to the lower case 9 by the attachment portion 12. Thereafter, the lower case 9 is filled with a liquid potting agent 41 to cure the potting agent 41. In this way, the connection unit 11 is attached to the lower case 9.

そして、接続ユニット１１のコネクタ３３をカメラユニット１０のＣＣＤ用コネクタ２７に嵌合させながら、ケース８，９同士を取り付ける。すると、取付部１２が、接続ユニット１１の基板３２を当該基板３２の表面に沿って移動することを許容しているので、コネクタ２７，３３の位置に応じて、接続ユニット１１の基板３２の位置が移動する。さらに、ロアケース９にグランドシェル４３を重ねて、リアパネル２の孔７を通ったねじ６がねじ孔にねじ込まれることで、電子機器モジュール１が自動車のリアパネル２に取り付けられる。 Then, the cases 8 and 9 are attached to each other while the connector 33 of the connection unit 11 is fitted to the CCD connector 27 of the camera unit 10. Then, since the attachment portion 12 allows the substrate 32 of the connection unit 11 to move along the surface of the substrate 32, the position of the substrate 32 of the connection unit 11 depends on the positions of the connectors 27 and 33. Move. Furthermore, the electronic device module 1 is attached to the rear panel 2 of the automobile by overlapping the ground shell 43 on the lower case 9 and screwing the screw 6 that has passed through the hole 7 of the rear panel 2 into the screw hole.

図８に、電子機器モジュール１とワイヤハーネス１０３とが接続された図を示す。ワイヤハーネス１０３は、ケーブル１１０と、その末端に設けられたコネクタ１０４と、を有している。ケーブル１１０は、周知のシールドケーブルであり、芯線１１４と絶縁被覆１１５とを備えた被覆導線１１６と、この被覆導線１１６を覆う導線性のシールド部材である編組１１２と、編組１１２に重ねられてその周囲を覆うシース１１１と、を備えている。 FIG. 8 shows a diagram in which the electronic device module 1 and the wire harness 103 are connected. The wire harness 103 has a cable 110 and a connector 104 provided at the end thereof. The cable 110 is a well-known shielded cable. The cable 110 is a covered conductive wire 116 including a core wire 114 and an insulating coating 115, a braid 112 that is a conductive shield member covering the coated conductive wire 116, and the braid 112 is overlapped with the braid 112. A sheath 111 covering the periphery.

コネクタ１０４は、ケーブル１１０が備える被覆導線１１６の絶縁被覆８１５が剥かれて露出された芯線１１４に電気的に接続された複数の雌型の端子金具１５０と、これら端子金具１５０を収容して支持する絶縁性のインナハウジング１２０と、インナハウジング１２０の外周に密に重ねられる導電性のシールドシェル１３０と、シールドシェル１３０の外周に密に重ねられる絶縁性のアウタハウジング１６０と、を備えている。 The connector 104 accommodates and supports a plurality of female terminal fittings 150 electrically connected to the core wire 114 exposed by peeling off the insulation coating 815 of the covered conductive wire 116 included in the cable 110 and the terminal fittings 150. Insulating inner housing 120, conductive shield shell 130 closely stacked on the outer periphery of inner housing 120, and insulating outer housing 160 closely stacked on the outer periphery of shield shell 130 are provided.

図８に示すように、電子機器モジュール１のコネクタ部１８とワイヤハーネス１０３のコネクタ１０４とが接続されると、コネクタ部１８内の端子部材７０が雄型の端子金具として機能して、コネクタ１０４が備える雌型の端子金具８５０と接触し、電子機器モジュール１に備えられたカメラユニット１０と、ケーブル１１０の先に接続された図示しないモニタ装置等とが接続される。 As shown in FIG. 8, when the connector portion 18 of the electronic device module 1 and the connector 104 of the wire harness 103 are connected, the terminal member 70 in the connector portion 18 functions as a male terminal fitting. The camera unit 10 provided in the electronic device module 1 is connected to a monitor device (not shown) connected to the end of the cable 110.

以上より、本発明によれば、端子部材７０が有する一対のアーム部７１の他方の端部７０ｂ間の隙間Ｄ２が、それに挿入されるＦＰＣ３４の電気接触部３４１の厚みと同じに形成されており、一対のアーム部７１の一方の端部７０ａ間の隙間Ｄ１が、それに挿入される端子部材取付部２１の厚みより小さく形成されているので、ＦＰＣ３４の電気接触部３４１を他方の端部７０ｂ間の隙間Ｄ２に容易に挿入することができるとともに、端子部材取付部２１を一方の端部７０ａ間の隙間Ｄ１に挿入すると一方の端部７０ａ間の隙間Ｄ１が広がることにより他方の端部７０ｂ間の隙間Ｄ２が狭まり、他方の端部７０ｂ間の隙間Ｄ２に挿入されたＦＰＣ３４の電気接触部３４１を強く挟み込んで接圧を高めることができる。そのため、組立性を向上できるとともに接触不良を防止できる。 As described above, according to the present invention, the gap D2 between the other end portions 70b of the pair of arm portions 71 of the terminal member 70 is formed to be the same as the thickness of the electrical contact portion 341 of the FPC 34 inserted therein. Since the gap D1 between the one end portions 70a of the pair of arm portions 71 is formed smaller than the thickness of the terminal member mounting portion 21 inserted therein, the electric contact portion 341 of the FPC 34 is connected between the other end portions 70b. Can be easily inserted into the gap D2, and when the terminal member mounting portion 21 is inserted into the gap D1 between the one end portions 70a, the gap D1 between the one end portions 70a widens, so that the gap between the other end portions 70b is increased. The gap D2 is narrowed, and the electric contact portion 341 of the FPC 34 inserted into the gap D2 between the other end portions 70b can be strongly sandwiched to increase the contact pressure. Therefore, it is possible to improve assemblability and prevent contact failure.

また、端子部材７０が有する一対のアーム部７１の一方の端部７０ａの先端７０ｃから支点部７２までの長さが、一対のアーム部７１の他方の端部７０ｂの先端７０ｄから支点部７２までの長さより長く形成されているので、てこの原理により、一方の端部７０ａ間の隙間Ｄ１を広げる力を小さく且つ他方の端部７０ｂ間の隙間Ｄ２を狭める力を大きくすることができるため、組立性をより向上できるとともに、接触不良をより防止できる。 Further, the length from the tip 70 c of one end portion 70 a of the pair of arm portions 71 of the terminal member 70 to the fulcrum portion 72 is from the tip 70 d of the other end portion 70 b of the pair of arm portions 71 to the fulcrum portion 72. Because of the lever principle, the force that widens the gap D1 between the one end portions 70a can be reduced and the force that narrows the gap D2 between the other end portions 70b can be increased. Assemblability can be further improved and contact failure can be further prevented.

また、端子部材７０が金属で形成されているとともにコネクタ部１８の雄型の端子金具として機能するので、同じく金属で形成されたワイヤハーネス１０３のコネクタ１０４が備える雌型の端子金具１５０との接圧を適正な値に設定することができ、そのため、コネクタ１０４を挿入に必要な力を低くすることができ、組み立て性をより向上できる。 Further, since the terminal member 70 is made of metal and functions as a male terminal fitting of the connector portion 18, it is in contact with the female terminal fitting 150 provided in the connector 104 of the wire harness 103 that is also made of metal. The pressure can be set to an appropriate value, so that the force required for inserting the connector 104 can be reduced, and the assemblability can be further improved.

なお、本実施形態においては、端子部材７０の一方の端部７０ａ間の隙間Ｄ１に、ロアケース９に設けられた端子部材取付部２１を挿入するものであったが、これに限らず、例えば、端子部材７０を雌型の端子金具とし、コネクタ部１８に接続される相手方のコネクタが備える雄型の端子金具をこの端子部材７０の一方の端部７０ａの間の隙間Ｄ１に挿入するようにしてもよい。この場合、相手方のコネクタが備える雄型の端子金具が、請求項中の被狭持部材に相当する。 In the present embodiment, the terminal member mounting portion 21 provided in the lower case 9 is inserted into the gap D1 between the one end portions 70a of the terminal member 70. The terminal member 70 is a female terminal fitting, and the male terminal fitting provided in the mating connector connected to the connector portion 18 is inserted into the gap D1 between the one end portions 70a of the terminal member 70. Also good. In this case, the male terminal fitting included in the mating connector corresponds to the pinched member in the claims.
