Description

本発明は、電線の端末に接続される端子金具と、電線及び端子金具を収容するハウジングと、ハウジングの内側に設けられて該端子金具と電線との接続部分を被覆するチューブと、を備えたコネクタに関する。 The present invention includes a terminal fitting connected to an end of an electric wire, a housing that houses the electric wire and the terminal fitting, and a tube that is provided inside the housing and covers a connection portion between the terminal fitting and the electric wire. Concerning connectors.

移動体としての自動車には、多種多様な電子機器が搭載されている。この電子機器に電力や制御信号などを伝えるためにワイヤハーネスが用いられる。ワイヤハーネスは、複数の電線とコネクタとを備えている。 A wide variety of electronic devices are mounted on automobiles as moving bodies. A wire harness is used to transmit electric power and control signals to the electronic device. The wire harness includes a plurality of electric wires and connectors.

従来、コネクタにおいて、電線と端子金具との接続部分の防水性を確保する構造が用いられてる。例えば、電線と端子金具との接続部分の近傍に充填剤を充填することで電線と端子金具との接続部分の防水性を確保したコネクタが知られている。しかしながら、充填剤内に気泡が発生することがあり、気泡が多く発生したことを確認するのが難しいとともに、気泡が多く発生した場合には、防水性能を確保することが困難だった。そこで、充填剤を用いる代わりに、ハウジングと電線との隙間及び、ハウジングと端子金具との隙間のそれぞれにパッキンを介在させて、電線と端子金具との接続部分の防水性を確保することを試みていたが、部品点数が多く組み立て作業が長時間化する問題があった。また、パッキンを用いたコネクタも、パッキンが正しい位置に取り付けられていることを確認するのが難しく、パッキンが正しい位置に取り付けられていない場合には、防水性能を確保することが困難だった。 2. Description of the Related Art Conventionally, in a connector, a structure that ensures waterproofness of a connection portion between an electric wire and a terminal fitting is used. For example, a connector is known in which a filler is filled in the vicinity of a connection portion between an electric wire and a terminal fitting to ensure waterproofness at the connection portion between the electric wire and the terminal fitting. However, in some cases, bubbles are generated in the filler, and it is difficult to confirm that many bubbles are generated, and when many bubbles are generated, it is difficult to ensure waterproof performance. Therefore, instead of using a filler, an attempt is made to secure the waterproof property of the connection portion between the electric wire and the terminal fitting by interposing a packing in each of the gap between the housing and the electric wire and the gap between the housing and the terminal fitting. However, there is a problem that the number of parts is large and assembly work takes a long time. In addition, it is difficult to confirm that the packing is attached at the correct position in the connector using the packing, and it is difficult to ensure the waterproof performance when the packing is not attached at the correct position.

これらの問題を解決した防油水コネクタが、特許文献１に開示されている。特許文献１に開示されたコネクタ１０１は、図６に示すように、電線１００の端末に接続される端子金具１０２と、端子金具１０２に装着される樹脂製のハウジング１０３と、電線１００と端子金具１０２との接続部分を覆うグロメット１０４と、を備えている。グロメット１０４は、その一端１０４Ａが電線１００に嵌合し、その他端１０４Ｂがハウジング１０３に密に嵌合して、電線１００とハウジング１０３との両方に固定されていた。 An oil-proof water connector that solves these problems is disclosed in Patent Document 1. As shown in FIG. 6, a connector 101 disclosed in Patent Document 1 includes a terminal fitting 102 connected to a terminal of an electric wire 100, a resin housing 103 attached to the terminal fitting 102, an electric wire 100, and a terminal fitting. , And a grommet 104 that covers a connection portion with the G.102. The grommet 104 was fixed to both the electric wire 100 and the housing 103 by fitting one end 104 A to the electric wire 100 and the other end 104 B closely fitting to the housing 103.

しかしながら、上述した従来のコネクタ１０１では、グロメット１０４は、その一端が電線１００に嵌合し、その他端がハウジング１０３に密に嵌合して、電線１００及びハウジング１０３の両方に固定されていたので、例えば、車両の走行中の振動などにより、電線１００が、その長手方向に沿う方向の端子金具１０２から離れる方向に引っ張られた場合には、グロメット１０４の他端１０４Ｂが引っ張られ、グロメット１０４とハウジング１０３との嵌合が外れて、電線１００と端子金具１０２との接続部分が浸水してしまう虞れがあった。 However, in the conventional connector 101 described above, the grommet 104 is fixed to both the electric wire 100 and the housing 103 because one end of the grommet 104 is fitted to the electric wire 100 and the other end is closely fitted to the housing 103. For example, when the electric wire 100 is pulled in a direction away from the terminal fitting 102 in the longitudinal direction due to vibration during traveling of the vehicle, the other end 104B of the grommet 104 is pulled, and the grommet 104 There is a possibility that the fitting with the housing 103 is released and the connection portion between the electric wire 100 and the terminal fitting 102 is submerged.
