PLUG-IN CONNECTOR AND CONNECTION STRUCTURE

To provide a plug-in connector in which a band connect has a spring property and which is capable of reducing, as further as possible, an area in which dissimilar metals are in contact with each other.SOLUTION: A plug-in connector 10 comprises: a plug 20 including a cylindrical part 21 holding a conductor 71 of one cable or a wire 70 and a pin part 22 including a pin 22A; and a socket 30 including a cylindrical part 31 holding the conductor 71 of the other cable or the wire 70 and an insert part 32 including an insertion port into which the pin 22A is inserted. A band contact 40 is provided between mutually opposed faces of the pin 22A and the insert part 32. The pin part 22 of the plug, the insertion port 32 of the socket and the band contact 40 are made of copper or copper alloy. The cylindrical part 21 of the plug 20 and the cylindrical part 31 of the socket 30 are made of copper or copper alloy, or aluminum or aluminum alloy correspondingly to a metal constituting the conductor 71.SELECTED DRAWING: Figure 2 【課題】バンドコンタクトがバネ性を有し、かつ、異種金属同士が接触する面積をできるだけ小さくすることが可能なプラグインコネクタを提供する。【解決手段】プラグインコネクタ１０は、一方のケーブル又は電線７０の導体７１を保持する筒状部２１とピン２２Ａを備えるピン部２２とを有するプラグ２０と、他方のケーブル又は電線７０の導体７１を保持する筒状部３１とピン２２Ａを挿入可能な差込口を備える差込部３２とを有するソケット３０とを備え、ピン２２Ａと差込部３２との相互の対向面の間にバンドコンタクト４０が設けられており、プラグのピン部２２とソケットの差込部３２とバンドコンタクト４０とは銅又は銅合金製であり、プラグ２０の筒状部２１とソケット３０の筒状部３１とは、導体７１を構成する金属に対応して、銅又は銅合金製、又はアルミニウム又はアルミニウム合金製である。【選択図】図２
