続いて、嵌合筒部１２に装着されるアース用の端子金具３０について説明する。端子金具３０は、導電性の金属板材から一体に形成され、図３に示す展開形状から形成される。詳しくは端子金具３０は、前方に突出するタブ３１を雌端子金具６０との対応する位置に四つ横並びで設けた接続部３２と、この接続部３２の後端に連なって嵌合筒部１２の内部に埋設される装着部３３と、この装着部３３の後端に連なって嵌合筒部１２の外部に突出して車両のボディ等のアース用部材９０（本発明の接地部に相当）にボルト２０で締め付け固定される取付部３４とからなる。   Next, the grounding terminal fitting 30 attached to the fitting cylinder portion 12 will be described. The terminal fitting 30 is integrally formed from a conductive metal plate material, and is formed from a developed shape shown in FIG. Specifically, the terminal fitting 30 includes a connecting portion 32 in which four tabs 31 protruding forward are provided side by side at positions corresponding to the female terminal fitting 60, and the fitting tube portion 12 connected to the rear end of the connecting portion 32. A mounting portion 33 embedded in the interior of the vehicle body and a grounding member 90 (corresponding to a grounding portion of the present invention) such as a vehicle body that projects from the fitting cylinder portion 12 to the rear end of the mounting portion 33. The mounting portion 34 is fastened and fixed by the bolt 20.

端子金具３０は、図３に示す折れ線Ｌに沿って折り曲げられて成形され、装着部３３がクランク状に屈曲されることで接続部３２と取付部３４とを接続部３２を上位とした段違い状に配して構成される。この折り曲げにより、装着部３３は、高さ方向に沿って延びる垂直部３５と前後方向に沿って延びる水平部３６とに形成され、水平部３６の前端が接続部３２の後端に連なるとともに、垂直部３５の下端が取付部３４の前端に連なるようになっている。   The terminal fitting 30 is formed by being bent along a fold line L shown in FIG. 3, and the mounting portion 33 is bent in a crank shape so that the connecting portion 32 and the mounting portion 34 are arranged in a stepped manner with the connecting portion 32 as the upper level. Arranged. By this bending, the mounting portion 33 is formed into a vertical portion 35 extending along the height direction and a horizontal portion 36 extending along the front-rear direction, and the front end of the horizontal portion 36 is continuous with the rear end of the connection portion 32. The lower end of the vertical part 35 is connected to the front end of the attachment part 34.

また、取付部３４は、図５に示すように、装着部３３に連なる基板部３７（本発明の第一板部に相当）とこの基板部３７の左右両側縁から内側へ折り返し状に延出する左右一対の折り返し部３８（本発明の第二板部に相当）とに形成され、基板部３７と折り返し部３８とが両側縁において半円弧部３９を介して連なるようになっている。各折り返し部３８と基板部３７とは板厚方向に密着状に重ね合わされ、これにより、本発明の二重板構造部４０が構成される。   Further, as shown in FIG. 5, the mounting portion 34 extends inwardly from a substrate portion 37 (corresponding to the first plate portion of the present invention) connected to the mounting portion 33 and from both left and right edges of the substrate portion 37. A pair of left and right folded portions 38 (corresponding to the second plate portion of the present invention) is formed, and the substrate portion 37 and the folded portion 38 are connected to each other through semicircular arc portions 39 at both side edges. Each folded portion 38 and the substrate portion 37 are overlapped in the plate thickness direction so as to form a double plate structure portion 40 of the present invention.

各折り返し部３８は、取付部３４の全長に亘って延びる細長い形状をなし、互いに左右対称形となっている。各折り返し部３８の自由端（延出端）の端面同士は、基板部３７の幅方向略中央（端子金具３０全体として見ても幅方向略中央）において互いに突き合わされており、したがって、各折り返し部３８は同一高さ位置で並列した構造となっている。
基板部３７において中央部から少し後端寄りの位置には、図３に示すように、略円形状のボルト通し孔４１が貫通して形成されており、各折り返し部３８の自由端の端面には、この両端面が互いに突き合わされたときに、全体としてボルト通し孔４１と整合し得る略半円弧状の切り欠き４２が対称状に一対形成されている。 Each folded-back portion 38 has an elongated shape extending over the entire length of the attachment portion 34 and is bilaterally symmetric. The end surfaces of the free ends (extending ends) of the folded portions 38 are abutted with each other at the approximate center in the width direction of the substrate portion 37 (approximately the center in the width direction even when viewed as the terminal fitting 30 as a whole). The portions 38 are structured in parallel at the same height position.
As shown in FIG. 3, a substantially circular bolt through hole 41 is formed in the substrate portion 37 at a position slightly closer to the rear end from the center portion, and is formed on the end surface of the free end of each folded portion 38. A pair of symmetrically semicircular arc-shaped notches 42 that can be aligned with the bolt through-hole 41 as a whole when the both end faces are abutted with each other.

そして、アース用の端子金具３０は、インサート成形によって嵌合筒部１２内に装着されている。詳しくは端子金具３０は、図６及び図７に示すように、装着部３３の全体つまり垂直部３５及び水平部３６と、取付部３４の前端部つまり装着部３３との連結部４３とを、嵌合筒部１２の奥壁１５の内部に埋め込んで構成されている。したがって、取付部３４は、連結部４３を除いた部分が嵌合筒部１２の外部に露出して配置されるとともに連結部４３が嵌合筒部１２の内部に埋入して配置され、もって二重板構造部４０が雄ハウジング１０の内外に亘って形成されるようにしている。また、端子金具３０における装着部３３の水平部３６には、略方形状の透孔４４が開設されており、図２に示すように、インサート成形によって透孔４４内に樹脂材が埋まることにより、端子金具３０の嵌合筒部１２からの抜けや位置ずれが確実に阻止されるようになっている。   And the terminal fitting 30 for earth | grounding is mounted | worn in the fitting cylinder part 12 by insert molding. Specifically, as shown in FIGS. 6 and 7, the terminal fitting 30 includes the entire mounting portion 33, that is, the vertical portion 35 and the horizontal portion 36, and the front end portion of the mounting portion 34, that is, the connecting portion 43 with the mounting portion 33. It is configured to be embedded in the back wall 15 of the fitting cylinder portion 12. Accordingly, the attachment portion 34 is disposed with the portion excluding the connection portion 43 exposed to the outside of the fitting tube portion 12 and the connection portion 43 is disposed in the fitting tube portion 12. A double plate structure 40 is formed over the inside and outside of the male housing 10. Further, a substantially rectangular through hole 44 is formed in the horizontal portion 36 of the mounting portion 33 of the terminal fitting 30. As shown in FIG. 2, the resin material is buried in the through hole 44 by insert molding. The terminal metal 30 is reliably prevented from coming off from the fitting cylinder portion 12 and from being displaced.

次に、本実施形態に係るアースジョイントコネクタの使用方法の一例を示すと、まず、端子金具３０をインサートとしてインサート成形された雄ハウジング１０に対して雌コネクタ５０を嵌合させ、ロックアーム１１のロック受け部１８とロック部５５との弾性係止に基づいて両コネクタをロックする。これにより、図７に示すように、雌コネクタ５０に装着された雌端子金具６０は、嵌合筒部１２の奥壁１５の前面から突出した対応するタブ３１と嵌合接続される。これと前後して、端子金具３０の取付部３４を車両のボディ等のアース用部材９０の上面に載せた状態で、取付部３４のボルト通し孔４１に対して上方からボルト２０を挿通し、ボルト２０の頭部２１で取付部３４をアース用部材９０との間に板厚方向に締め付けて固定する。これにより、雌コネクタ５０に収容された雌端子金具６０、ひいてはそれに接続されたアース用の電線７０が端子金具３０を介してアースに落とされる。   Next, an example of a method of using the ground joint connector according to the present embodiment will be described. First, the female connector 50 is fitted into the male housing 10 that is insert-molded using the terminal fitting 30 as an insert, and the lock arm 11 is Both connectors are locked based on the elastic locking between the lock receiving portion 18 and the lock portion 55. As a result, as shown in FIG. 7, the female terminal fitting 60 attached to the female connector 50 is fitted and connected to the corresponding tab 31 protruding from the front surface of the back wall 15 of the fitting cylinder portion 12. Before and after this, with the mounting portion 34 of the terminal fitting 30 placed on the upper surface of the grounding member 90 such as the body of the vehicle, the bolt 20 is inserted from above into the bolt through hole 41 of the mounting portion 34. The mounting portion 34 is fastened and fixed in the plate thickness direction between the head portion 21 of the bolt 20 and the grounding member 90. As a result, the female terminal fitting 60 accommodated in the female connector 50, and thus the grounding electric wire 70 connected thereto, is dropped to the ground via the terminal fitting 30.

その後、本実施形態に係るアースジョイントコネクタが振動環境下に置かれ、端子金具３０のうちボルト２０の締め付け部分と雄ハウジング１０の後端面との間に露出する部分に大きな応力が作用しても、本実施形態の場合には、この部分を構成する取付部３４が二重板構造部４０となっており、しかもこの二重板構造部４０の一部（連結部４３）が雄ハウジング１０の内部にも埋め込まれた構造となっているから、取付部３４の強度が高められ、取付部３４の折損等が起こる事態を回避できる。   Thereafter, even when the earth joint connector according to the present embodiment is placed in a vibration environment and a large stress acts on a portion of the terminal fitting 30 exposed between the tightening portion of the bolt 20 and the rear end surface of the male housing 10. In the case of this embodiment, the mounting portion 34 constituting this portion is a double plate structure portion 40, and a part of the double plate structure portion 40 (connecting portion 43) is the male housing 10. Since the structure is embedded in the interior, the strength of the mounting portion 34 is increased, and a situation in which the mounting portion 34 is broken can be avoided.

また、雄ハウジング１０が二重板構造部４０の一部（連結部４３）と装着部３３の周囲を覆うインサート成形によって形成されているから、二重板構造部４０の一部と雄ハウジング１０の樹脂材とが互いに密着状態で接し合うこととなり、振動等に対する機械的耐性がより一層向上する。
さらに、二重板構造部４０が基板部３７とその両側縁から幅方向中央に向けて折り返されて互いの自由端の端面同士を突き合わせた一対の折り返し部３８とにより構成されるから、かかる二重板構造部４０を歩留まり良く簡単に成形することができる。 Further, since the male housing 10 is formed by insert molding that covers a part of the double plate structure part 40 (the connecting part 43) and the periphery of the mounting part 33, a part of the double plate structure part 40 and the male housing 10 are formed. These resin materials are in close contact with each other, and the mechanical resistance to vibration and the like is further improved.
Further, the double plate structure portion 40 is constituted by the substrate portion 37 and a pair of folded portions 38 which are folded back from the both side edges toward the center in the width direction and the end surfaces of the respective free ends are brought into contact with each other. The heavy plate structure 40 can be easily formed with a good yield.
