Description

本発明は、例えば自動車の電気系統等に用いて好適な防水コネクタに関するものである。   The present invention relates to a waterproof connector suitable for use in, for example, an electric system of an automobile.

一般に、自動車の電気系統に用いられる防水コネクタは、インナーハウジングとアウターハウジングが別部品からなる組立式のものであり、この防水コネクタは、図35に示すように、互いに嵌合可能な雄側コネクタ100と雌側コネクタ101とからなる。   In general, a waterproof connector used in an electric system of an automobile is an assembly type in which an inner housing and an outer housing are separate parts, and this waterproof connector is a male connector that can be fitted to each other as shown in FIG. 100 and a female connector 101.

雄側コネクタ100は、絶縁樹脂材からなる楕円筒形のアウターハウジング103を備えており、このアウターハウジング103は、相手コネクタ嵌合部103Aと、この相手コネクタ嵌合部103Aに連なる中空部104を有していて、この中空部104には、インナーハウジング105と、このインナーハウジング105の外周に被着された金属シェル112が挿嵌してある。そして、このインナーハウジング105には端子収容室106が形成してあり、端子収容室106にはシールド線107の絶縁芯線108に接続されたターミナルである雄側接続端子109が収容してある。この場合、相手コネクタ嵌合部103Aから端子収容室106の先側に雄側リテーナ110を挿入することで、ランス111を押し下げて雄側接続端子109を固定するようにしてある。   The male connector 100 includes an oval cylindrical outer housing 103 made of an insulating resin material. The outer housing 103 includes a mating connector fitting portion 103A and a hollow portion 104 connected to the mating connector fitting portion 103A. In addition, an inner housing 105 and a metal shell 112 attached to the outer periphery of the inner housing 105 are inserted into the hollow portion 104. The inner housing 105 is formed with a terminal accommodating chamber 106, and the terminal accommodating chamber 106 accommodates a male connection terminal 109 which is a terminal connected to the insulating core wire 108 of the shield wire 107. In this case, by inserting the male retainer 110 from the mating connector fitting portion 103A to the front side of the terminal accommodating chamber 106, the lance 111 is pushed down to fix the male connection terminal 109.

そして、シールド線107は防水用シール部材114を挿通しており、防水用シール部材114は中空部104とシールド線107の間を水密状態に封止している。   The shield wire 107 is inserted through the waterproof seal member 114, and the waterproof seal member 114 seals the space between the hollow portion 104 and the shield wire 107 in a watertight state.

また、雌側コネクタ101は雄側コネクタ100と略同様に構成してあり、絶縁樹脂材からなる楕円筒形のアウターハウジング203は相手コネクタ嵌合部203Aと、この相手コネクタ嵌合部203Aに連なる中空部204を有しており、この中空部204にはインナーハウジング205とこのインナーハウジング205の外周に被着された金属シェル214が挿嵌してあり、このインナーハウジング205の端子収容室206にはシールド線207の絶縁芯線208に接続されたターミナルである雌側接続端子209が収容してある。この場合、相手コネクタ嵌合部203Aから端子収容室206の先側に雌側リテーナ210を挿入することで、ランス211を押して下げて雌側接続端子209を固定するようにしてある。   The female connector 101 is configured in substantially the same manner as the male connector 100, and an oval cylindrical outer housing 203 made of an insulating resin material is connected to the mating connector fitting portion 203A and the mating connector fitting portion 203A. A hollow portion 204 is provided, and an inner housing 205 and a metal shell 214 attached to the outer periphery of the inner housing 205 are inserted into the hollow portion 204, and the terminal housing chamber 206 of the inner housing 205 is inserted into the hollow portion 204. Accommodates a female connection terminal 209 which is a terminal connected to the insulated core wire 208 of the shield wire 207. In this case, by inserting the female retainer 210 from the mating connector fitting portion 203A to the front side of the terminal accommodating chamber 206, the lance 211 is pushed down to fix the female connection terminal 209.

また、雌側コネクタ101のインナーハウジング205の外壁面にはシール部材212が装着してあるし、また、シールド線207は防水用シール部材213を挿通しており、防水用シール部材213は中空部204とシールド線207の間を水密状態に封止している。   Further, a seal member 212 is mounted on the outer wall surface of the inner housing 205 of the female connector 101, the shield wire 207 is inserted through the waterproof seal member 213, and the waterproof seal member 213 is a hollow portion. The space between 204 and the shield wire 207 is sealed in a watertight state.

このように構成された雄側コネクタ100と雌側コネクタ101とが結合されると、雄側接続端子109が雌側接続端子209に挿入され、雄側コネクタ100のインナーハウジング105と、雌側コネクタ101のインナーハウジング205とは、先端面同士で当接状態となる。同時に、雄側コネクタ100のアウターハウジング103は、雌側コネクタ101の相手コネクタ嵌合部203Aに挿入される。この際、シール部材212が雄側コネクタ100のアウターハウジング103の内壁面と雌側コネクタ101のインナーハウジング205の外壁面との間に位置して防水するようになる(特許文献1参照)。

しかしながら、上記した従来の防水コネクタは大型であったために小型化が望まれていた。このような防水コネクタを小型化した場合、雄側コネクタ100の相手コネクタ嵌合部103Aが小さくなって、相手コネクタ嵌合部103Aから雄側リテーナ110を端子収容室106の先側に挿入操作する操作性が悪くなり、雄側リテーナ110の挿入操作に治具等が必要になるし、同様に、雌側コネクタ101でも、相手コネクタ嵌合部203Aが小さくなって、相手コネクタ嵌合部203Aから雌側リテーナ210を端子収容室212の先側に挿入操作する操作性が悪くなり、雌側リテーナ210の挿入操作に治具等が必要になるという問題が生じていた。   However, since the conventional waterproof connector described above is large, downsizing is desired. When such a waterproof connector is reduced in size, the mating connector fitting portion 103A of the male connector 100 becomes small, and the male retainer 110 is inserted into the front side of the terminal accommodating chamber 106 from the mating connector fitting portion 103A. The operability is deteriorated, and a jig or the like is required for the insertion operation of the male retainer 110. Similarly, in the female connector 101, the mating connector fitting portion 203A becomes small, and the mating connector fitting portion 203A is separated from the mating connector fitting portion 203A. There has been a problem that the operability of inserting the female retainer 210 into the front side of the terminal accommodating chamber 212 is deteriorated, and a jig or the like is required for the inserting operation of the female retainer 210.

また、小型化の際に、雄側リテーナ110及び雌側リテーナ210の操作性を良くするために、雄側リテーナ110を相手コネクタ嵌合部103Aまで伸ばし、また、雌側リテーナ210を相手コネクタ嵌合部203Aまで伸ばそうとしても、雄側コネクタ101と雌側コネクタ102とを、雄側接続端子109を雌側接続端子209に対向させて配置した状態で対峙させた際に、雄側リテーナ110と雌側リテーナ210とが対向する位置関係にあるために、伸ばすことができない。   Further, in order to improve the operability of the male retainer 110 and the female retainer 210 during downsizing, the male retainer 110 is extended to the mating connector fitting portion 103A, and the female retainer 210 is fitted with the mating connector. Even if the male side connector 101 and the female side connector 102 are opposed to each other with the male side connection terminal 109 facing the female side connection terminal 209 even if the male side connector 101 and the female side connector 102 are opposed to each other. Since the female retainer 210 and the female retainer 210 are in a positional relationship facing each other, they cannot be extended.

また、シール部材212を、雄側コネクタ100のアウターハウジング103の内壁面と雌側コネクタ101のインナーハウジング205の外壁面との間に位置させて防水させていたために、シール部材212の厚さ分、防水コネクタが大型化するという問題があった。   Further, since the sealing member 212 is positioned between the inner wall surface of the outer housing 103 of the male connector 100 and the outer wall surface of the inner housing 205 of the female connector 101, the sealing member 212 is waterproofed.
