本発明は、それぞれが複数の接続端子を保持する２つのハウジングを嵌合した後に、これら両ハウジングの複数の接続端子を押圧することが可能な押圧部材を備えたコネクタ装置に関する。   The present invention relates to a connector device provided with a pressing member capable of pressing a plurality of connection terminals of both housings after fitting two housings each holding a plurality of connection terminals.

従来、例えば電気自動車の駆動源としての電気モータに電流を供給する電流供給経路に設けられ、電力ハーネス同士、又は電力ハーネスとモータもしくはインバータとの間を着脱可能とするコネクタが用いられている。この種のコネクタとして、第１コネクタ部と第２コネクタ部とを結合し、両コネクタ部のそれぞれの接合端子同士を押圧して接触させるものが知られている（例えば、特許文献１参照）。   2. Description of the Related Art Conventionally, for example, a connector that is provided in a current supply path that supplies current to an electric motor as a drive source of an electric vehicle and that is detachable between power harnesses or between a power harness and a motor or an inverter is used. As this type of connector, there is known a connector in which a first connector portion and a second connector portion are coupled to each other so as to press and contact the respective connecting terminals of both the connector portions (for example, see Patent Document 1).

特許文献１に記載されたコネクタは、複数の第１接合端子、及び複数の第１接合端子に一体的に固定された複数の絶縁部材が収容された第１ターミナルハウジングを有する第１コネクタ部と、複数の第２接合端子が収容された第２ターミナルハウジングを有する第２コネクタ部とを備え、第１ターミナルハウジングと第２ターミナルハウジングとを嵌合させると、第１接合端子と第２接合端子とが絶縁部材を介して交互に配置される積層状態となるように構成されている。   The connector described in Patent Document 1 includes a first connector portion having a first terminal housing in which a plurality of first joining terminals and a plurality of insulating members fixed integrally to the plurality of first joining terminals are accommodated. And a second connector portion having a second terminal housing in which a plurality of second joint terminals are accommodated, and when the first terminal housing and the second terminal housing are fitted together, the first joint terminal and the second joint terminal Are stacked so as to be alternately arranged via insulating members.

このコネクタはさらに、積層状態となった複数の第１接合端子、複数の第２接合端子、及び複数の絶縁部材を積層方向に押圧することで、複数の第１接合端子と複数の第２接合端子とを各接点にて一括して固定し、電気的に接続させる接続部材を第１ターミナルハウジング内に備えている。この接続部材は、複数の第１接合端子及び複数の絶縁部材を積層方向に貫通する軸部と、軸部の一端に設けられ、締め付け工具を嵌合させる異形穴が形成された頭部と、軸部の他端に設けられ、第１ターミナルハウジングに形成された雌ネジに螺合する雄ネジが形成されたネジ部とを有している。   The connector further presses the plurality of first joining terminals, the plurality of second joining terminals, and the plurality of insulating members that are in the laminated state in the laminating direction, so that the plurality of first joining terminals and the plurality of second joining are provided. The first terminal housing is provided with a connecting member that fixes the terminals together at each contact and electrically connects them. The connecting member includes a shaft portion that penetrates the plurality of first joining terminals and the plurality of insulating members in the stacking direction, a head portion that is provided at one end of the shaft portion, and has a deformed hole that fits a tightening tool, A screw portion provided at the other end of the shaft portion and formed with a male screw that is screwed into a female screw formed in the first terminal housing.

しかして、接続部材を締め付け工具によって回転させると、ネジ部の螺合によって頭部が軸方向に移動し、頭部が弾性部材を介して複数の絶縁部材のうち最も頭部側に位置する絶縁部材を積層方向に押圧し、これによって複数の第１接合端子と複数の第２接合端子とが電気的に接続される。   Thus, when the connecting member is rotated by the tightening tool, the head is moved in the axial direction by screwing of the screw portion, and the head is insulated most closely among the plurality of insulating members via the elastic member. The members are pressed in the stacking direction, whereby the plurality of first joint terminals and the plurality of second joint terminals are electrically connected.

（本実施の形態の作用及び効果）
以上説明した本実施の形態によれば、以下のような効果が得られる。 (Operation and effect of the present embodiment)
According to the present embodiment described above, the following effects can be obtained.

（１）雄側接続端子８１〜８３と押圧部材７の軸部７ｂとの間に第１〜第３絶縁部材９４，９５，９６の筒部９４１，９５１，９６１が介在するので、軸部７ｂを例えば絶縁性樹脂によってコーティングするような絶縁加工を施すことなく、押圧部材７の軸部７ｂを介した雄側接続端子８１〜８３間の短絡や漏電を防止することができる。つまり、軸部７ｂを絶縁性樹脂によってコーティングするような場合、製造工程において、コーティングするという別の工程が発生するが、本発明の場合、第１〜第３絶縁部材９４，９５，９６の成型の際、一緒に、筒部９４１，９５１，９６１も成型できるため、非常に製造がし易い。また、筒部９４１，９５１，９６１は、本体部９４０，９５０，９６０から積層方向に突出しているので、第１〜第３絶縁部材９４〜９６同士の隙間を形成する際にも、利用できる。 (1) Since the cylindrical portions 941, 951, 961 of the first to third insulating members 94, 95, 96 are interposed between the male side connection terminals 81-83 and the shaft portion 7b of the pressing member 7, the shaft portion 7b For example, the short circuit between the male side connection terminals 81-83 via the axial part 7b of the press member 7 and an electrical leakage can be prevented, without performing the insulation process which coats these with insulating resin. That is, when the shaft portion 7b is coated with an insulating resin, another process of coating occurs in the manufacturing process. In the present invention, the first to third insulating members 94, 95, and 96 are molded. At this time, since the cylindrical portions 941, 951 and 961 can be molded together, it is very easy to manufacture. Further, since the cylindrical portions 941, 951, 961 protrude from the main body portions 940, 950, 960 in the stacking direction, they can be used when forming gaps between the first to third insulating members 94-96.

（２）受け部材９３及び第１〜第３絶縁部材９４，９５，９６は、筒部９４１，９５１，９６１によって相互に連結されるので、第１〜第３絶縁部材９４，９５，９６を雄側ハウジング９０内に保持する保持構造を簡略化することが可能となる。 (2) Since the receiving member 93 and the first to third insulating members 94, 95, 96 are connected to each other by the cylindrical portions 941, 951, 961, the first to third insulating members 94, 95, 96 are male. The holding structure held in the side housing 90 can be simplified.

（３）押圧部材７及び雄側ハウジング９０のアウタハウジング９１を金属によって構成したので、例えばこれらの部材を樹脂から構成した場合に比較して、強度及び耐久性を高めることができる。 (3) Since the pressing member 7 and the outer housing 91 of the male housing 90 are made of metal, for example, the strength and durability can be improved as compared with the case where these members are made of resin.

（４）押圧部材７は、ネジ部７ｃがインナハウジング９２の雌ネジ９１ｄに螺合することで軸方向移動し、軸部７ｂを介してネジ部７ｃと一体に形成された頭部７ａが押圧力を出力するので、簡素な構成で押圧力を発生する機構を構成することができる。また、軸部７ｂによって雄側接続端子８１〜８３の位置のずれを抑制することも可能となる。 (4) The pressing member 7 moves in the axial direction when the screw portion 7c is screwed into the female screw 91d of the inner housing 92, and the head portion 7a formed integrally with the screw portion 7c is pressed by the shaft portion 7b. Since the pressure is output, it is possible to configure a mechanism that generates a pressing force with a simple configuration. Further, it is possible to suppress the displacement of the positions of the male side connection terminals 81 to 83 by the shaft portion 7b.

（５）第１及び第２絶縁部材９４，９５に形成された貫通孔９４ａ，９５ａは、筒部側の小径部９４ａ_１，９５ａ_１と、本体部側の大径部９４ａ_２，９５ａ_２とを有し、その大径部９４ａ_２，９５ａ_２に、積層方向に隣り合う他の第２又は第３絶縁部材９５，９６の筒部９５１，９６１を収容している。このように構成することにより、本体部９４０，９５０，９６０から積層方向に突出する筒部９４１，９５１，９６１の高さをより大きくすることができる。これにより、押圧部材７の軸部７ｂに対して、直交方向に交わるように配置される各絶縁部材（第１及び第２絶縁部材９４，９５）が傾き難くなり（図４参照）、その結果、押圧部材７による押圧において、積層方向に、各絶縁部材（第１及び第２絶縁部材９４，９５）がスムーズに移動でき、適切に、押圧部材７による押圧が完了することができる。 (5) The through holes 94a and 95a formed in the first and second insulating members 94 and 95 include the small diameter portions 94a ₁ and 95a ₁ on the cylindrical portion side, and the large diameter portions 94a ₂ and 95a ₂ on the main body portion side. The cylindrical portions 951 and 961 of the other second or third insulating members 95 and 96 adjacent to each other in the stacking direction are accommodated in the large diameter portions 94a ₂ and 95a ₂ . By comprising in this way, the height of the cylinder parts 941, 951, 961 which protrude in the lamination direction from the main-body parts 940, 950, 960 can be enlarged more. Thereby, each insulating member (the 1st and 2nd insulating members 94 and 95) arrange | positioned so that it may orthogonally cross with respect to the axial part 7b of the press member 7 becomes difficult to incline (refer FIG. 4), and the result In the pressing by the pressing member 7, the insulating members (first and second insulating members 94, 95) can smoothly move in the stacking direction, and the pressing by the pressing member 7 can be completed appropriately.
