PROBLEM TO BE SOLVED: To provide a connector plug that can reduce a peak value of a force amount necessary in inserting the connector plug into a receptacle, using a simple configuration.SOLUTION: A connector plug to be connected to a receptacle that is a connection object paired with the connector plug includes an insertion part having an outer peripheral surface at which an electrode part having a plurality of electrodes is arranged, and inserted into the receptacle. A tip of the insertion part is formed with a profiled portion with a profiled shape where distances from end parts of at least part of the electrodes of the electrode part to a tip in a surface containing the electrodes are different from each other.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】簡易な構成で、コネクタプラグをレセプタクルに挿入する際に必要な力量のピーク値を低減させることができるコネクタプラグを提供すること。【解決手段】コネクタプラグは、対をなす接続対象のレセプタクルに接続されるコネクタプラグであって、複数の電極を有する電極部が外周面に配置されており、前記レセプタクルに挿入される挿入部を備え、前記挿入部の先端には、前記電極部の少なくとも一部の前記電極の端部から、該電極を含む面内における先端までの距離が異なる異形形状の異形部が形成されている。【選択図】図2
