A connector as described in Japanese Patent Application Laid-Open No. 2012-119263 (Patent Document 1) is provided at the end of such an electric wire, and a terminal fitting attached to the electric wire is accommodated in the housing of the connector. Thus, it is configured to be connected to a counterpart terminal provided in the electric device.
　ところで、コネクタが接続される電気機器の周辺に他部材が配設される等して、電線を直線状に配索することが困難である場合があり、電線を屈曲して配索する必要が生じることがある。しかし、電線を屈曲して配索しようとすると、電線が円弧状に曲げられるために大きな配索スペースが必要になるという問題があった。特に、電気自動車やハイブリッドカーに用いられる電線は、高圧電流に対応するために太く剛性が高いことから、そのような電線を屈曲させようとすると大きな円弧を描くこととなって、より大きな配索スペースが必要であった。 By the way, it may be difficult to route the electric wire in a straight line by arranging other members around the electrical equipment to which the connector is connected, and it is necessary to bend and wire the electric wire. May occur. However, if the electric wire is bent and arranged, there is a problem that a large arrangement space is required because the electric wire is bent in an arc shape. In particular, electric wires used in electric cars and hybrid cars are thick and rigid to handle high-voltage currents, so if you try to bend such electric wires, you will draw a large arc, and a larger wiring Space was needed.
　そこで、特開２００８－２８８１１６号公報（特許文献２）には、電線を相手方端子と接続する端子金具として、相手方端子との接続部が、電線が取り付けられる電線取付部に対して直交して突出するＬ字型端子金具を用いたＬ字型コネクタが開示されている。このようなＬ字型コネクタを用いれば、相手方端子との接続方向に直交して電線を配索出来ることから、電線の配索スペースを小さくすることが出来る。 Therefore, in Japanese Patent Application Laid-Open No. 2008-288116 (Patent Document 2), as a terminal fitting for connecting an electric wire to a counterpart terminal, a connection portion with the counterpart terminal protrudes perpendicularly to an electric wire attachment portion to which the electric wire is attached. An L-shaped connector using an L-shaped terminal fitting is disclosed. If such an L-shaped connector is used, the electric wire can be routed orthogonal to the connection direction with the counterpart terminal, so that the wiring space for the electric wire can be reduced.
　しかし、特許文献２に記載のＬ字型コネクタにおいては、Ｌ字型端子金具をコネクタハウジングに差し込んで収容するために、コネクタハウジングに大きな開口を形成する必要があり、コネクタハウジングの大型化を招くという問題があった。更に、防水性を確保するためには、ハウジングの開口部分を別部材で封止する必要があり、部品点数が増加すると共に、組立工数が増加するという問題があった。 However, in the L-shaped connector described in Patent Document 2, it is necessary to form a large opening in the connector housing in order to insert and accommodate the L-shaped terminal fitting in the connector housing, leading to an increase in the size of the connector housing. There was a problem. Furthermore, in order to ensure waterproofness, it is necessary to seal the opening of the housing with a separate member, which increases the number of parts and the number of assembly steps.
　また、特表２０１２－５０２４４２号公報（特許文献３）には、電線に取り付けられる電線側の金具にばね構造（特許文献３の符号３５）を設けて、該ばね構造によって、相手方端子との接続部が形成された端子側の金具（符号５１）をコネクタハウジング内で接続するＬ字型コネクタが開示されている。しかし、特許文献３に記載の構造では、ばね構造によって端子側の金具との接点数が多くなり、接触抵抗が大きくなるおそれがあった。また、ばね構造において、車両走行時の振動等で位置ずれを生じて、接続安定性が損なわれるおそれがあった。 Also, in Japanese Translation of PCT International Publication No. 2012-502442 (Patent Document 3), a spring structure (reference numeral 35 of Patent Document 3) is provided on the metal fitting on the electric wire side attached to the electric wire, and the spring structure allows connection with the counterpart terminal. An L-shaped connector for connecting a terminal-side metal fitting (reference numeral 51) formed with a portion in a connector housing is disclosed. However, in the structure described in Patent Document 3, the number of contacts with the metal fitting on the terminal side is increased due to the spring structure, and the contact resistance may be increased. Further, in the spring structure, there is a possibility that the connection stability may be impaired due to a displacement due to vibration or the like when the vehicle travels.

　本発明は、上述の事情を背景に為されたものであって、その解決課題は、コネクタハウジングへの組付性に優れ、相手方端子に対して、電気的にも物理的にも安定して接続することの出来る、新規な構造のＬ字型端子金具、およびそれを用いた新規な構造のＬ字型コネクタを提供することにある。 The present invention has been made in the background of the above-described circumstances, and its solution is excellent in assembling to the connector housing, and is electrically and physically stable with respect to the counterpart terminal. An object is to provide an L-shaped terminal fitting having a novel structure that can be connected, and an L-shaped connector having a novel structure using the same.
　Ｌ字型端子金具に関する本発明の第一の態様は、相手方端子と接続される接続部と、電線に取り付けられる電線取付部とを備え、前記接続部が、前記電線取付部の延伸方向に対して直交して突出されているＬ字型端子金具において、前記接続部が形成された端子金具と、該端子金具と別体形成されて前記電線取付部が形成された電線金具とを含んで構成されていると共に、前記端子金具と前記電線金具の一方にはボルト部が形成されていると共に、前記端子金具と前記電線金具の他方にはネジ孔が形成されており、前記端子金具には、該端子金具を前記ボルト部と前記ネジ孔の螺合方向に回転させる工具と係合可能な工具係合部が形成されていることを、特徴とする。 The 1st aspect of this invention regarding an L-shaped terminal metal fitting is provided with the connection part connected with an other party terminal, and the electric wire attachment part attached to an electric wire, The said connection part is with respect to the extending direction of the said electric wire attachment part. In the L-shaped terminal fitting protruding orthogonally, the terminal fitting is formed including the terminal fitting formed with the connecting portion, and the electric wire fitting formed separately from the terminal fitting and formed with the wire mounting portion. In addition, a bolt portion is formed on one of the terminal fitting and the electric wire fitting, and a screw hole is formed on the other of the terminal fitting and the electric wire fitting. A tool engaging portion that can be engaged with a tool that rotates the terminal fitting in the screwing direction of the bolt portion and the screw hole is formed.
　本発明に従う構造とされたＬ字型端子金具においては、相手方端子と接続される端子金具と、電線が取り付けられる電線金具が互いに別体構造とされている。そして、端子金具および電線金具に形成されたボルト部とネジ孔が相互に螺合することによって、端子金具を電線金具に取り付けられるようになっている。従って、端子金具が電線金具に直接にボルト締結されることから、端子金具と電線金具を強固に固定することが出来る。これにより、大きな接触荷重を得ることが出来て、接触抵抗を低減して電気的に安定して接続することが出来ると、物理的にも安定的に接続することが出来る。 In the L-shaped terminal metal fitting configured according to the present invention, the terminal metal fitting connected to the counterpart terminal and the electric wire fitting to which the electric wire is attached are separated from each other. Then, the bolts and the screw holes formed in the terminal fitting and the electric wire fitting are screwed together so that the terminal fitting can be attached to the electric wire fitting. Therefore, since the terminal fitting is directly bolted to the electric wire fitting, the terminal fitting and the electric wire fitting can be firmly fixed. As a result, if a large contact load can be obtained and the contact resistance can be reduced and the electrical connection can be made stably, the connection can be made physically and stably.
　また、端子金具と電線金具が互いに別体品とされていることから、コネクタハウジング内に組み込む場合には、Ｌ字形状のハウジングのキャビティの一方の開口から電線金具を差し込んだ後に、他方の開口から端子金具を差し込んで電線金具に螺着することで組み込みを完了することが出来る。その結果、組立作業を容易にすることが出来ると共に、コネクタハウジングの小型化を図ることが出来る。 In addition, since the terminal metal fitting and the electric wire fitting are separate from each other, when the wire fitting is inserted into the connector housing, after inserting the electric wire fitting from one opening of the cavity of the L-shaped housing, the other opening Assembling can be completed by inserting the terminal fitting from the screw and screwing it onto the electric wire fitting. As a result, assembly work can be facilitated and the connector housing can be miniaturized.
　特に、端子金具には、工具と係合する工具係合部が形成されている。これにより、端子金具自体をボルトまたはナットとして、電線金具に螺着することが出来る。従って、端子金具と電線金具とを締結するボルトなどを別途に用意する必要がなく、部品点数を削減することが出来る。更に、コネクタハウジングのキャビティに、端子金具と電線金具を差し込む差込口以外の開口を形成する必要がないことから、コネクタハウジングの防水性を向上することが出来る。 In particular, the terminal fitting is formed with a tool engaging portion that engages with the tool. Thereby, the terminal fitting itself can be screwed to the electric wire fitting as a bolt or a nut. Therefore, it is not necessary to separately prepare bolts for fastening the terminal fitting and the electric wire fitting, and the number of parts can be reduced. Furthermore, since it is not necessary to form an opening other than the insertion port for inserting the terminal fitting and the electric wire fitting in the cavity of the connector housing, the waterproofness of the connector housing can be improved.
　なお、端子金具の接続部の形状は、相手方端子の形状に応じて各種の形状が採用可能であって、雄端子形状でも良いし、雌端子形状でも良い。また、工具係合部の形状についても、使用される工具に応じて適宜に設定可能であって、例えばスパナやレンチに対応する六角ナット形状や、六角レンチに対応する六角溝形状、マイナスドライバーやプラスドライバーに対応するマイナスやプラスの溝形状等でも良い。 In addition, the shape of the connection part of a terminal metal fitting can employ | adopt various shapes according to the shape of an other party terminal, A male terminal shape may be sufficient and a female terminal shape may be sufficient. Also, the shape of the tool engaging portion can be appropriately set according to the tool to be used. For example, a hexagonal nut shape corresponding to a spanner or a wrench, a hexagonal groove shape corresponding to a hexagonal wrench, a flat screwdriver, A minus or plus groove shape corresponding to a plus driver may be used.
　Ｌ字型端子金具に関する本発明の第二の態様は、前記第一の態様に記載のものにおいて、前記工具係合部が、前記端子金具の外周面に形成されているものである。 A second aspect of the present invention relating to an L-shaped terminal fitting is the one described in the first aspect, wherein the tool engaging portion is formed on the outer peripheral surface of the terminal fitting.
　本態様によれば、端子金具における工具との係合面と、端子金具の中心軸との距離を可及的に大きく確保することが出来る。これにより、工具で端子金具を電線金具に螺着する際の締付トルクを大きく得ることが出来て、端子金具を電線金具により強固に固定することが出来る。 According to this aspect, the distance between the engagement surface of the terminal fitting with the tool and the center axis of the terminal fitting can be as large as possible. Thereby, it is possible to obtain a large tightening torque when the terminal fitting is screwed to the electric wire fitting with a tool, and the terminal fitting can be firmly fixed by the electric wire fitting.
　Ｌ字型端子金具に関する本発明の第三の態様は、前記第一又は第二の態様に記載のものにおいて、前記工具係合部が、前記端子金具に形成された前記ボルト部又は前記ネジ孔の形成面と反対の面上に形成されているものである。 A third aspect of the present invention relating to an L-shaped terminal metal fitting is the one described in the first or second aspect, wherein the tool engaging portion is the bolt part or the screw hole formed in the terminal metal fitting. It is formed on the surface opposite to the formation surface.
　本態様においては、工具係合部が、端子金具の内側に形成されている。従って、端子金具の外形寸法を小さくすることが出来て、Ｌ字型端子金具の小型化を図ることが出来る。 In this aspect, the tool engaging portion is formed inside the terminal fitting. Therefore, the external dimensions of the terminal fitting can be reduced, and the L-shaped terminal fitting can be miniaturized.
　Ｌ字型端子金具に関する本発明の第四の態様は、前記第一～第三の何れか１つの態様に記載のものにおいて、前記端子金具に前記ボルト部が形成されていると共に、前記電線金具に前記ネジ孔が形成されているものである。 According to a fourth aspect of the present invention relating to an L-shaped terminal fitting, in the one described in any one of the first to third aspects, the terminal fitting is provided with the bolt portion, and the electric wire fitting. Are formed with the screw holes.
　本態様においては、端子金具自体がボルトとして構成されている。そして、相手方端子との接続部が形成されることによりロッド形状とされる端子金具に、同じくロッド形状のボルト部が形成されることから、旋盤加工等を用いて端子金具を容易に製造することが出来る。また、電線金具のネジ孔は、例えば電線金具の本体部分を金属板で形成すると共に、該金属板にナットを溶着等することによって、容易に形成することが出来る。 In this aspect, the terminal fitting itself is configured as a bolt. And since the rod-shaped bolt part is also formed in the rod-shaped terminal metal fitting by forming the connection part with the counterpart terminal, the terminal metal fitting can be easily manufactured using lathe processing etc. I can do it. Further, the screw hole of the electric wire fitting can be easily formed by, for example, forming the main body portion of the electric wire fitting with a metal plate and welding a nut to the metal plate.
　Ｌ字型コネクタに関する本発明は、Ｌ字形状を有するＬ字型端子金具がハウジングに収容されたＬ字型コネクタにおいて、前記Ｌ字型端子金具として前記Ｌ字型端子金具に関する本発明の第一～第四の何れか１つの態様に記載のＬ字型端子金具を用いると共に、前記ハウジングには、前記Ｌ字型端子金具の前記端子金具が差し込まれる端子金具差込孔と、前記電線金具が差し込まれる電線金具差込孔とが直交して内部で連通して形成されており、前記端子金具差込孔および前記電線金具差込孔が、それぞれ、他方との連通部と反対側の端部においてのみ前記ハウジングの外部に開口されていることを、特徴とする。 The present invention relating to an L-shaped connector is an L-shaped connector in which an L-shaped terminal fitting having an L-shape is accommodated in a housing, and the first of the present invention relating to the L-shaped terminal fitting as the L-shaped terminal fitting. The L-shaped terminal fitting according to any one of the fourth aspect is used, and the housing includes a terminal fitting insertion hole into which the terminal fitting of the L-shaped terminal fitting is inserted, and the electric wire fitting. The terminal fitting insertion hole and the wire fitting insertion hole are respectively formed in an end portion on the opposite side to the communicating portion with the other. It is characterized by being opened only to the outside of the housing.
　本発明に従う構造とされたＬ字型コネクタによれば、端子金具と電線金具が別体形成された本発明のＬ字型端子金具を用いることから、端子金具と電線金具をハウジングの端子金具差込孔と電線金具差込孔に対してそれぞれの軸方向で差し込むことが可能であり、ハウジングに大きな開口を形成する必要が無く、ハウジングの小型化を図ることが出来る。そして、端子金具と電線金具自体が螺着構造を有することから、別体のボルトで締結する場合のように、ボルトへのアクセス用の開口等をハウジングに設ける必要がなく、ハウジングの開口を、端子金具の差込口と電線金具の差込口のみに限定することが出来る。これにより、ハウジングの防水性を向上することが出来る。 According to the L-shaped connector structured according to the present invention, since the L-shaped terminal fitting of the present invention in which the terminal fitting and the electric wire fitting are separately formed is used, the terminal fitting and the electric wire fitting are connected to the terminal fitting difference of the housing. It is possible to insert into the insertion hole and the wire fitting insertion hole in the respective axial directions, and it is not necessary to form a large opening in the housing, and the housing can be downsized. And since the terminal metal fitting and the electric wire fitting itself have a screwed structure, there is no need to provide an opening for accessing the bolt in the housing as in the case of fastening with a separate bolt, and the opening of the housing is It can be limited to the terminal fitting insertion port and the wire fitting insertion port only. Thereby, the waterproofness of a housing can be improved.
　本発明のＬ字型端子金具においては、相手方端子と接続する端子金具と、電線と接続する電線金具とを別体構造にすると共に、端子金具と電線金具にボルト部とネジ孔を形成して、端子金具を電線金具に直接に螺着するようにした。これにより、少ない部品点数で容易に組み立てることが出来ると共に、端子金具と電線金具との間の接触荷重を大きく確保することが出来て、端子金具と電線金具を電気的および物理的に安定的に接続することが出来る。そして、このようなＬ字型端子金具を用いたＬ字型コネクタによれば、ハウジングの開口を、端子金具と電線金具の差込口のみに限定できることから、優れた防水性を得ることが出来る。 In the L-shaped terminal fitting of the present invention, the terminal fitting to be connected to the counterpart terminal and the electric wire fitting to be connected to the electric wire are separated, and a bolt portion and a screw hole are formed in the terminal fitting and the electric wire fitting. The terminal fitting is screwed directly to the electric wire fitting. As a result, it is possible to easily assemble with a small number of parts, and to ensure a large contact load between the terminal fitting and the wire fitting, so that the terminal fitting and the wire fitting can be electrically and physically stable. It can be connected. And according to the L-shaped connector using such an L-shaped terminal metal fitting, since the opening of a housing can be limited only to the insertion port of a terminal metal fitting and an electric wire metal fitting, the outstanding waterproofness can be acquired. .

　以下、本発明の実施形態について、図面を参照しつつ説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　先ず、図１および図２に、Ｌ字型端子金具に関する本発明の第一の実施形態としてのＬ字型端子金具１０を分解状態で示す。Ｌ字型端子金具１０は、端子金具１２が、電線金具１４に螺着される構造とされている。 First, FIGS. 1 and 2 show an L-shaped terminal fitting 10 as a first embodiment of the present invention relating to an L-shaped terminal fitting in an exploded state. The L-shaped terminal fitting 10 has a structure in which a terminal fitting 12 is screwed to a wire fitting 14.
　端子金具１２は、金属からなる一体成形品とされている。端子金具１２は、基部１６から接続部１８とボルト部２０が互いに反対方向に突出されたロッド形状とされている。接続部１８は、図示しない相手方端子と接続可能な形状に形成される。接続部１８の具体的形状は、相手方端子の形状に対応して各種の形状が採用可能である。本実施形態における接続部１８は、基部１６から突出する円筒形状とされており、周方向で所定間隔に分断されてなる複数の接触片２１を有する雌端子形状とされている。そして、図示しない例えば電気自動車のインバータに設けられた相手方端子としての円形断面の雄端子が接続部１８に差し込まれることで、接続部１８が相手方端子と接続されるようになっている。なお、接続部１８の内面の開口端部はテーパ面２２が形成されて拡径されており、雄端子の差し込みが容易とされている。 The terminal fitting 12 is an integrally molded product made of metal. The terminal fitting 12 has a rod shape in which the connecting portion 18 and the bolt portion 20 protrude from the base portion 16 in opposite directions. The connecting portion 18 is formed in a shape that can be connected to a counterpart terminal (not shown). Various shapes can be adopted as the specific shape of the connecting portion 18 corresponding to the shape of the counterpart terminal. The connecting portion 18 in the present embodiment has a cylindrical shape protruding from the base portion 16 and has a female terminal shape having a plurality of contact pieces 21 divided at a predetermined interval in the circumferential direction. For example, a male terminal having a circular cross section as a counterpart terminal provided in an inverter of an electric vehicle (not shown) is inserted into the connection portion 18 so that the connection portion 18 is connected to the counterpart terminal. In addition, the opening edge part of the inner surface of the connection part 18 is formed with the taper surface 22, and it is diameter-expanded, and insertion of a male terminal is made easy.
　また、基部１６は、中実のブロック形状とされている。本実施形態における基部１６は、接続部１８の外径寸法よりも僅かに大きな正六角形状とされている。これにより、基部１６の外周面２４は６つの平面から形成されており、基部１６の外周面２４が、工具係合部とされている。 Also, the base portion 16 has a solid block shape. The base portion 16 in the present embodiment has a regular hexagonal shape slightly larger than the outer diameter dimension of the connecting portion 18. Thereby, the outer peripheral surface 24 of the base part 16 is formed from six planes, and the outer peripheral surface 24 of the base part 16 is used as a tool engaging part.
　さらに、基部１６における接続部１８と反対側の面には、ボルト部２０が突設されている。ボルト部２０は、基部１６の中心軸：Ｏ上を接続部１８と反対方向に突出して延びる雄ねじ形状とされている。即ち、端子金具１２には、基部１６とボルト部２０によって、基部１６を頭部とすると共に、ボルト部２０をネジ部として、接続部１８の外径寸法よりも僅かに大きな二面幅を有する六角ボルトが形成されており、六角ボルトのボルト頭部からネジ部と反対方向に接続部１８が突出された一体成形品とされている。このような端子金具１２は、例えば旋盤加工等を用いて効率良く形成することが出来る。 Furthermore, a bolt portion 20 is projected from the surface of the base portion 16 opposite to the connection portion 18. The bolt portion 20 has a male screw shape extending on the central axis O of the base portion 16 so as to protrude in the direction opposite to the connecting portion 18. That is, the terminal fitting 12 has a base 16 and a bolt 20 that have the base 16 as a head and the bolt 20 as a screw and has a two-sided width slightly larger than the outer diameter of the connecting portion 18. Hexagonal bolts are formed, and the connection part 18 is projected from the bolt head of the hexagonal bolt in the direction opposite to the threaded part. Such a terminal fitting 12 can be efficiently formed using, for example, lathe processing.
　一方、電線金具１４は、金属板から形成された本体部２６に、金属製のナット２８が固着された一体品とされて、端子金具１２と別体形成されている。本体部２６の一方の端部には貫通孔が形成されており、ナット２８が貫通孔と同軸上で本体部２６に溶接等で固着されることにより、ナット２８の中心軸上に貫設された雌ねじによって、ネジ孔３０が形成されている。なお、ナット２８は、従来から広く用いられているナットが採用可能であり、本実施形態においては、汎用的なナットを利用することで電線金具１４を容易に形成することが可能とされているが、切削等で本体部２６にナット形状を一体形成することも勿論可能である。 On the other hand, the electric wire fitting 14 is an integral product in which a metal nut 28 is fixed to a main body portion 26 formed of a metal plate, and is formed separately from the terminal fitting 12. A through hole is formed at one end of the main body portion 26, and the nut 28 is coaxially connected to the through hole and fixed to the main body portion 26 by welding or the like, thereby penetrating on the central axis of the nut 28. A screw hole 30 is formed by the female screw. As the nut 28, a conventionally widely used nut can be used. In the present embodiment, the wire fitting 14 can be easily formed by using a general-purpose nut. However, it is of course possible to integrally form the nut shape on the main body portion 26 by cutting or the like.
　また、電線金具１４におけるネジ孔３０と反対側の端部には、電線取付部３２が形成されている。電線取付部３２は、本体部２６に一体形成された平板状の突片形状とされており、容易に湾曲変形可能とされている。 Further, a wire attachment portion 32 is formed at the end of the wire fitting 14 opposite to the screw hole 30. The electric wire attachment portion 32 has a flat-plate-like protruding piece shape integrally formed with the main body portion 26, and can be easily bent and deformed.
　これら端子金具１２と電線金具１４を含んで構成されたＬ字型端子金具１０は、ワイヤハーネス等の電線３４の端末において絶縁膜３６から露出された芯線３８が電線金具１４に重ね合わされて、電線取付部３２でかしめ等で固定されることにより、電線３４の端末に電線金具１４が取り付けられる。そして、電線金具１４のネジ孔３０に端子金具１２のボルト部２０が螺合されることによって、図３に示すように、電線金具１４に端子金具１２が固定されるようになっている。これにより、Ｌ字型端子金具１０は、端子金具１２の接続部１８が、電線金具１４の電線取付部３２の延伸方向（図２中、上下方向）に対して直交して突出するＬ字形状を有している。 The L-shaped terminal fitting 10 including the terminal fitting 12 and the electric wire fitting 14 is configured such that the core wire 38 exposed from the insulating film 36 at the end of the electric wire 34 such as a wire harness is superimposed on the electric wire fitting 14. The wire fitting 14 is attached to the end of the electric wire 34 by being fixed by caulking or the like at the attachment portion 32. Then, when the bolt portion 20 of the terminal fitting 12 is screwed into the screw hole 30 of the electric wire fitting 14, the terminal fitting 12 is fixed to the electric wire fitting 14 as shown in FIG. 3. Thereby, the L-shaped terminal fitting 10 has an L-shape in which the connecting portion 18 of the terminal fitting 12 protrudes perpendicularly to the extending direction (vertical direction in FIG. 2) of the electric wire attachment portion 32 of the electric wire fitting 14. have.
　次に、図４に、このようなＬ字型端子金具１０を用いた、Ｌ字型コネクタに関する本発明の一実施形態としてのＬ字型コネクタ４０の断面を示す。Ｌ字型コネクタ４０は、上述の如きＬ字型端子金具１０が、ハウジング４２に収容されて構成されている。 Next, FIG. 4 shows a cross-section of an L-shaped connector 40 as an embodiment of the present invention relating to an L-shaped connector using such an L-shaped terminal fitting 10. The L-shaped connector 40 is configured by housing the L-shaped terminal fitting 10 as described above in a housing 42.
　ハウジング４２は、合成樹脂から形成された一体成形品とされている。ハウジング４２は、直角に屈曲された略Ｌ字の筒形状を有しており、直線状に延びる端子金具差込孔４４と、端子金具差込孔４４に直交して延びる電線金具差込孔４６が、それぞれの一方の端部においてハウジング４２内で相互に連通されている。そして、端子金具差込孔４４において電線金具差込孔４６との連通部と反対側の端部が、ハウジング４２の外部に開口されて端子金具差込口４８が形成されていると共に、電線金具差込孔４６において端子金具差込孔４４との連通部と反対側の端部が、ハウジング４２の外部に開口されて電線金具差込口５０が形成されている。特に本実施形態においては、端子金具差込孔４４および電線金具差込孔４６は、それぞれ、端子金具差込口４８および電線金具差込口５０においてのみハウジング４２の外部と連通されており、ハウジング４２の外部との開口部が、端子金具差込口４８と電線金具差込口５０のみに限定されている。 The housing 42 is an integrally molded product formed from a synthetic resin. The housing 42 has a substantially L-shaped cylindrical shape bent at a right angle, and includes a terminal fitting insertion hole 44 extending linearly and a wire fitting insertion hole 46 extending orthogonally to the terminal fitting insertion hole 44. Are in communication with each other within the housing 42 at one end of each. An end of the terminal fitting insertion hole 44 opposite to the communication portion with the wire fitting insertion hole 46 is opened to the outside of the housing 42 to form a terminal fitting insertion port 48. An end of the insertion hole 46 opposite to the communicating portion with the terminal fitting insertion hole 44 is opened to the outside of the housing 42 to form a wire fitting insertion port 50. In particular, in this embodiment, the terminal fitting insertion hole 44 and the electric wire fitting insertion hole 46 communicate with the outside of the housing 42 only at the terminal fitting insertion port 48 and the electric wire fitting insertion port 50, respectively. 42 is limited to the terminal fitting insertion port 48 and the electric wire fitting insertion port 50 only.
　そして、ハウジング４２の電線金具差込口５０に、電線３４の端末に取り付けられた電線金具１４が差し込まれる。本実施形態における電線金具１４には、保護キャップ５２が外挿されている。保護キャップ５２は合成樹脂から形成された略有底筒形状とされている。保護キャップ５２には、金属製の固定筒体５４が外挿されている。一方、電線金具１４が取り付けられた電線３４の端末の絶縁膜３６には、金属製の連結筒体５６の一方の端部がかしめ固定されており、連結筒体５６の他方の端部が、電線金具１４側に開口する開口端部５８とされている。そして、保護キャップ５２と固定筒体５４が電線金具１４に外挿されると共に、連結筒体５６の開口端部５８に差し込まれて、開口端部５８がかしめられることにより、保護キャップ５２と固定筒体５４が、電線金具１４の外挿状態で固定されている。 Then, the electric wire fitting 14 attached to the end of the electric wire 34 is inserted into the electric wire fitting insertion port 50 of the housing 42. A protective cap 52 is extrapolated to the wire fitting 14 in the present embodiment. The protective cap 52 has a substantially bottomed cylindrical shape formed from a synthetic resin. A metal fixed cylinder 54 is externally inserted into the protective cap 52. On the other hand, one end of a metallic connecting cylinder 56 is caulked and fixed to the insulating film 36 at the end of the electric wire 34 to which the electric wire fitting 14 is attached, and the other end of the connecting cylinder 56 is It is set as the opening edge part 58 opened to the electric wire metal fitting 14 side. Then, the protective cap 52 and the fixed cylinder 54 are extrapolated to the electric wire fitting 14 and are inserted into the opening end 58 of the connecting cylinder 56 so that the opening end 58 is caulked, whereby the protective cap 52 and the fixed cylinder 54 are inserted. The body 54 is fixed in an extrapolated state of the wire fitting 14.
　これら保護キャップ５２と固定筒体５４が外挿された電線金具１４が、ハウジング４２の電線金具差込口５０から電線金具差込孔４６に差し込まれると共に、固定筒体５４に切り起こされて形成された係止片６０が、電線金具差込孔４６内に形成された段差面６２に係止されることにより、電線金具１４が、電線金具差込孔４６内で固定されるようになっている。なお、電線金具１４が差し込まれた後の電線金具差込口５０には、蛇腹の筒形状とされたシールゴム６４が圧入されると共に、合成樹脂製の蓋部材６５が固定されることで、水密性が確保されている。 The wire fitting 14 in which the protective cap 52 and the fixed cylinder 54 are externally inserted is inserted into the wire fitting insertion hole 46 from the wire fitting insertion port 50 of the housing 42 and is cut and raised to the fixed cylinder 54. When the locking piece 60 is locked to the stepped surface 62 formed in the electric wire fitting insertion hole 46, the electric wire fitting 14 is fixed in the electric wire fitting insertion hole 46. Yes. In addition, a seal rubber 64 having a bellows-like shape is press-fitted into the electric wire fitting insertion port 50 after the electric wire fitting 14 is inserted, and a synthetic resin lid member 65 is fixed. Is secured.
　そして、図５に示すように、端子金具１２が、ボルト部２０を前方にして、端子金具差込口４８から端子金具差込孔４４に差し込まれる。端子金具１２は、工具としてのレンチ６６が外挿されて、六角形断面とされたレンチ６６の内周面が基部１６の外周面２４に係合した状態で、端子金具差込孔４４に差し込まれる。そして、端子金具１２は、保護キャップ５２および固定筒体５４を貫通して形成された貫通孔６７に挿通されて、レンチ６６によってボルト部２０とネジ孔３０との螺合方向に回転されることにより、ボルト部２０がハウジング４２内で電線金具１４のネジ孔３０と螺合される。これにより、図４に示したように、端子金具１２が電線金具１４に螺着されて、Ｌ字型端子金具１０が、ハウジング４２内に組み付けられる。 As shown in FIG. 5, the terminal fitting 12 is inserted into the terminal fitting insertion hole 44 from the terminal fitting insertion port 48 with the bolt portion 20 facing forward. The terminal fitting 12 is inserted into the terminal fitting insertion hole 44 in a state where a wrench 66 as a tool is extrapolated and the inner peripheral surface of the wrench 66 having a hexagonal cross section is engaged with the outer peripheral surface 24 of the base portion 16. It is. The terminal fitting 12 is inserted into a through hole 67 formed through the protective cap 52 and the fixed cylinder 54 and rotated in the screwing direction between the bolt portion 20 and the screw hole 30 by a wrench 66. Thus, the bolt portion 20 is screwed into the screw hole 30 of the wire fitting 14 in the housing 42. As a result, as shown in FIG. 4, the terminal fitting 12 is screwed to the electric wire fitting 14, and the L-shaped terminal fitting 10 is assembled in the housing 42.
　なお、端子金具差込孔４４に差し込まれた端子金具１２には、接続カバー６８が外挿される。接続カバー６８は合成樹脂から形成されている。接続カバー６８は、端子金具１２の接続部１８の外径寸法よりも僅かに大きな内径寸法を有する円筒状の挿通部７０と、挿通部７０と同軸上で、挿通部７０よりも小さな外径寸法と内径寸法を有する円筒状の案内部７２とが形成された段付筒形状とされている。案内部７２の外周面には、挿通部７０側に向けて拡径する三角板形状の複数のガイドリブ７４が、周方向の適宜の位置に形成されている。また、接続カバー６８には、金属製の保護筒体７６が外挿されている。このような接続カバー６８は、端子金具差込口４８から差し込まれて、電線金具１４に固定された端子金具１２に外挿される。なお、接続カバー６８の案内部７２側の端部は、端子金具差込口４８からハウジング４２の外方に突出して配設されている。これにより、端子金具１２の接続部１８に、接続カバー６８の挿通部７０が外挿されて、相手方端子との接続に際する接続部１８の過度の拡開を抑えると共に、接続部１８と同軸上に位置された案内部７２の内周面で相手方端子を案内することによって、接続部１８への差し込みを円滑に行なえるようになっている。 Note that the connection cover 68 is externally inserted into the terminal fitting 12 inserted into the terminal fitting insertion hole 44. The connection cover 68 is made of synthetic resin. The connection cover 68 includes a cylindrical insertion portion 70 having an inner diameter that is slightly larger than the outer diameter of the connection portion 18 of the terminal fitting 12, and an outer diameter that is coaxial with the insertion portion 70 and smaller than the insertion portion 70. And a cylindrical guide portion 72 having an inner diameter is formed into a stepped cylinder shape. On the outer peripheral surface of the guide portion 72, a plurality of triangular plate-shaped guide ribs 74 whose diameter is increased toward the insertion portion 70 are formed at appropriate positions in the circumferential direction. A metal protective cylinder 76 is externally inserted into the connection cover 68. Such a connection cover 68 is inserted from the terminal fitting insertion port 48 and is externally inserted into the terminal fitting 12 fixed to the electric wire fitting 14. Note that the end portion of the connection cover 68 on the guide portion 72 side is disposed so as to protrude from the terminal fitting insertion port 48 to the outside of the housing 42. As a result, the insertion portion 70 of the connection cover 68 is extrapolated to the connection portion 18 of the terminal fitting 12 to suppress excessive expansion of the connection portion 18 when connecting to the counterpart terminal, and to be coaxial with the connection portion 18. The other terminal is guided on the inner peripheral surface of the guide part 72 positioned above, so that the connection part 18 can be smoothly inserted.
　上述の如き構造とされたＬ字型端子金具１０およびＬ字型コネクタ４０によれば、Ｌ字型端子金具１０において、端子金具１２と電線金具１４が互いに別体構造とされている。そして、端子金具１２にボルト部２０が形成されると共に、電線金具１４にネジ孔３０が形成されていることから、ハウジング４２に電線金具１４を挿し込んだ後に、端子金具１２の基部１６の外周面２４に工具を係合して、端子金具１２をハウジング４２内で回転させて電線金具１４に螺着することで、Ｌ字型端子金具１０をハウジング４２内に容易に組み込むことが出来る。 According to the L-shaped terminal fitting 10 and the L-shaped connector 40 configured as described above, the terminal fitting 12 and the wire fitting 14 are separated from each other in the L-shaped terminal fitting 10. And since the bolt part 20 is formed in the terminal metal fitting 12 and the screw hole 30 is formed in the electric wire fitting 14, after inserting the electric wire fitting 14 in the housing 42, the outer periphery of the base 16 of the terminal fitting 12 The L-shaped terminal fitting 10 can be easily assembled in the housing 42 by engaging the tool with the surface 24, rotating the terminal fitting 12 in the housing 42, and screwing the terminal fitting 12 into the electric wire fitting 14.
　そして、端子金具１２が電線金具１４に対して、ボルト部２０とネジ孔３０との螺合構造で固着されることから、端子金具１２の電線金具１４への接触荷重を大きく確保することが出来る。これにより、端子金具１２と電線金具１４との接触抵抗を低減することが出来て、相手方端子と電気的に安定して接続することが出来ると共に、物理的にも安定して接続することが出来る。特に本実施形態においては、端子金具１２の基部１６の外周面２４が工具係合部とされており、端子金具１２の中心軸：Ｏからの距離が大きく確保されることから、レンチ６６による締付トルクを大きく確保して、電線金具１４により強固に固着することが出来る。更にまた、端子金具１２にボルト部２０が一体形成されていることから、端子金具１２を電線金具１４に固着するために別途にボルト等を用いる必要が無く、部品点数を削減することが出来る。 And since the terminal metal fitting 12 is fixed to the electric wire fitting 14 by a screwed structure of the bolt portion 20 and the screw hole 30, a large contact load of the terminal fitting 12 to the electric wire fitting 14 can be secured. . As a result, the contact resistance between the terminal fitting 12 and the wire fitting 14 can be reduced, and it can be electrically and stably connected to the counterpart terminal, and can be physically and stably connected. . In particular, in the present embodiment, the outer peripheral surface 24 of the base 16 of the terminal fitting 12 is a tool engaging portion, and a large distance from the central axis O of the terminal fitting 12 is ensured. A large attached torque can be secured and the wire fitting 14 can be firmly fixed. Furthermore, since the bolt portion 20 is integrally formed with the terminal fitting 12, there is no need to use a bolt or the like separately for fixing the terminal fitting 12 to the electric wire fitting 14, and the number of parts can be reduced.
　更にまた、端子金具１２を中心軸回りで回転して電線金具１４に直接に螺着することから、ハウジング４２に形成される端子金具差込孔４４と電線金具差込孔４６は、端子金具１２および電線金具１４を挿通可能な大きさをもって形成すれば足る。これにより、ハウジング４２の小型化を図ることが出来る。更に、別途にボルト等を用いて端子金具１２を電線金具１４に固定する場合のように、ハウジング４２にボルトにアクセスするための開口を設けることも不要とされる。従って、ハウジング４２の開口を端子金具差込口４８と電線金具差込口５０のみに限定することが出来、Ｌ字型コネクタ４０の防水性を向上することも出来る。 Furthermore, since the terminal fitting 12 is rotated around the central axis and screwed directly into the electric wire fitting 14, the terminal fitting insertion hole 44 and the electric wire fitting insertion hole 46 formed in the housing 42 are provided in the terminal fitting 12 as shown in FIG. It is sufficient to form the wire fitting 14 with a size that allows the wire fitting 14 to be inserted. Thereby, size reduction of the housing 42 can be achieved. Further, it is not necessary to provide an opening for accessing the bolt in the housing 42 as in the case where the terminal fitting 12 is fixed to the electric wire fitting 14 using bolts or the like. Therefore, the opening of the housing 42 can be limited only to the terminal fitting insertion port 48 and the electric wire fitting insertion port 50, and the waterproofness of the L-shaped connector 40 can be improved.
　なお、端子金具に形成される工具係合部は、使用される工具に応じて各種の形状が採用可能である。以下に、Ｌ字型端子金具に関する本発明の異なる実施形態を幾つか例示するが、本発明の具体的態様は、以下のものに限定されない。また、以下の実施形態は、端子金具の具体的形状が異なるのみであることから、端子金具のみを示し、前記第一の実施形態と同様の構造については、図中に第一の実施形態と同一の符号を付することにより、その説明を省略する。 It should be noted that various shapes can be adopted for the tool engaging portion formed on the terminal fitting depending on the tool used. Several different embodiments of the present invention relating to the L-shaped terminal fitting will be exemplified below, but the specific aspects of the present invention are not limited to the following. In addition, since the following embodiments are only different in specific shapes of the terminal fittings, only the terminal fittings are shown, and the structure similar to the first embodiment is different from that of the first embodiment in the figure. The description is abbreviate | omitted by attaching | subjecting the same code | symbol.
　図６に、Ｌ字型端子金具に関する本発明の第二の実施形態としての端子金具８０の正面視を示す。端子金具８０には、基部１６においてボルト部２０（図１等参照）が形成された面と反対側の面上に、工具係合部としての六角溝８２が形成されている。六角溝８２は、正六角形断面をもって接続部１８の突出方向と同方向に開口する有底の溝形状とされており、端子金具８０の中心軸：Ｏと同一中心軸上に形成されている。なお、本実施形態における基部１６は、正面視において円形状とされており、基部１６の外周面２４は、円周面とされている。 FIG. 6 shows a front view of a terminal fitting 80 as a second embodiment of the present invention relating to an L-shaped terminal fitting. The terminal fitting 80 is formed with a hexagonal groove 82 as a tool engaging portion on the surface of the base portion 16 opposite to the surface on which the bolt portion 20 (see FIG. 1 or the like) is formed. The hexagonal groove 82 has a bottomed groove shape having a regular hexagonal cross section and opening in the same direction as the protruding direction of the connecting portion 18, and is formed on the same central axis as the central axis O of the terminal fitting 80. Note that the base portion 16 in the present embodiment is circular in a front view, and the outer peripheral surface 24 of the base portion 16 is a circumferential surface.
　本実施形態によれば、工具としての図示しない六角レンチ等を六角溝８２に差し込んで係合することによって、端子金具８０を中心軸：Ｏ回りで回転させて電線金具１４に螺着することが出来る。そして、六角溝８２が基部１６の中央に形成されることから、基部１６の外径寸法を小さくすることが出来て、端子金具８０を小さくすることが出来る。なお、六角溝８２に代えて、工具としての三角形断面のレンチ等と係合する三角形状の溝等も採用可能である。 According to this embodiment, by inserting a hexagonal wrench (not shown) as a tool into the hexagonal groove 82 and engaging it, the terminal fitting 80 can be rotated around the central axis O and screwed to the wire fitting 14. I can do it. And since the hexagonal groove | channel 82 is formed in the center of the base 16, the outer diameter dimension of the base 16 can be made small and the terminal metal fitting 80 can be made small. Instead of the hexagonal groove 82, a triangular groove that engages with a triangular wrench or the like as a tool may be employed.
　次に、図７に、Ｌ字型端子金具に関する本発明の第三の実施形態としての端子金具９０の正面視を示す。端子金具９０には、基部１６においてボルト部２０と反対側の面上に、工具係合部としてのマイナス溝９２が形成されている。マイナス溝９２は、正面視において円形状とされた基部１６の径方向に延びて、接続部１８の突出方向と同方向に開口する有底の溝形状とされており、端子金具９０の中心軸：Ｏを通って形成されている。なお、マイナス溝９２は、基部１６の径方向の全長に亘って形成されており、接続部１８は、マイナス溝９２の形成部分において周方向で分断されている。 Next, FIG. 7 shows a front view of a terminal fitting 90 as a third embodiment of the present invention relating to an L-shaped terminal fitting. The terminal fitting 90 is formed with a minus groove 92 as a tool engaging portion on the surface of the base portion 16 opposite to the bolt portion 20. The minus groove 92 has a bottomed groove shape that extends in the radial direction of the base portion 16 that is circular when viewed from the front and opens in the same direction as the protruding direction of the connection portion 18. : Formed through O The minus groove 92 is formed over the entire length of the base portion 16 in the radial direction, and the connecting portion 18 is divided in the circumferential direction at the portion where the minus groove 92 is formed.
　本実施形態の端子金具９０は、工具としての図示しないマイナスドライバー等をマイナス溝９２に差し込んで係合することによって、端子金具９０を中心軸：Ｏ回りで回転させて電線金具１４に螺着することが出来る。そして、マイナス溝９２が、基部１６におけるボルト部２０と反対側の面上に形成されていることから、基部１６の外径寸法を小さくすることが出来ると共に、マイナス溝９２が基部１６の径方向の全長に亘って形成されていることから、端子金具９０の小径化を図りつつ、有効な締付トルクを得ることが出来る。なお、マイナス溝９２に代えて、工具としてのプラスドライバーと係合するプラス形状の溝等も採用可能である。 The terminal fitting 90 of the present embodiment is screwed into the wire fitting 14 by rotating the terminal fitting 90 around the central axis: O by inserting and engaging a minus driver (not shown) as a tool into the minus groove 92 as a tool. I can do it. Since the minus groove 92 is formed on the surface of the base portion 16 opposite to the bolt portion 20, the outer diameter of the base portion 16 can be reduced, and the minus groove 92 is formed in the radial direction of the base portion 16. Therefore, an effective tightening torque can be obtained while the diameter of the terminal fitting 90 is reduced. Instead of the minus groove 92, a plus-shaped groove that engages with a plus screwdriver as a tool may be employed.
　以上、本発明の実施形態について詳述したが、本発明はその具体的な記載によって限定されない。例えば、端子金具と電線金具に設けられるボルト部とネジ孔は、端子金具側にネジ孔を設けて、電線金具側にボルト部を設けてもよい。 As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited by the specific description. For example, the bolt portion and screw hole provided in the terminal fitting and the electric wire fitting may be provided with a screw hole on the terminal fitting side and a bolt portion on the electric wire fitting side.
　また、端子金具における接続部の具体的形状は、接続される相手方端子の形状に応じて各種のものが採用可能である。例えば、相手方端子が雌端子の場合には、接続部を雄端子形状で形成しても良い。 In addition, as the specific shape of the connecting portion in the terminal fitting, various types can be adopted depending on the shape of the counterpart terminal to be connected. For example, when the counterpart terminal is a female terminal, the connecting portion may be formed in a male terminal shape.
