特許文献１に開示されたプラグは、前壁部及び前壁部より後方に突出する筒状の周壁部を有するプラグ本体と、それぞれの前端部が前壁部から前方に突出するようにプラグ本体に収納される複数のプラグピンと、周壁部の両側にそれぞれ露設される一対の端子部及びプラグ本体内において一対の端子部同士を連結する連結部を有する接地端子と、を備える。   The plug disclosed in Patent Document 1 includes a plug body having a front wall portion and a cylindrical peripheral wall portion projecting rearward from the front wall portion, and a plug body so that each front end portion projects forward from the front wall portion.

特許文献１のプラグは、サーミスタを備えておらず、一対のピンでの発熱を検知できない。そこで、特許文献１のプラグに、特許文献２のようにサーミスタを設けることが考えられる。   The plug of Patent Document 1 does not include a thermistor and cannot detect heat generated by a pair of pins. Therefore, it is conceivable to provide a thermistor in the plug of Patent Document 1 as in Patent Document 2.

特許文献１のプラグでは、プラグ本体内に接地端子の連結部が存在する。そのため、特許文献１のプラグにサーミスタを設ける場合、サーミスタは、接地端子に接触しないように、接地端子の後方に配置する必要がある。この場合、プラグ本体は、接地端子の後方に配置されるサーミスタを収容できるような大きさにしなければならず、プラグ本体の大型化を避けることができない。また、サーミスタが接地端子の後方に配置されると、サーミスタとプラグピンとの距離が大きくなるから、一対のプラグピンでの発熱を精度よく検知することが難しい。   In the plug of Patent Document 1, there is a connecting portion of the ground terminal in the plug body. Therefore, when providing the thermistor in the plug of patent document 1, it is necessary to arrange | position a thermistor behind the ground terminal so that it may not contact a ground terminal. In this case, the plug body must be sized so as to accommodate the thermistor disposed behind the ground terminal, and an increase in the size of the plug body cannot be avoided. In addition, when the thermistor is disposed behind the ground terminal, the distance between the thermistor and the plug pin is increased, so that it is difficult to accurately detect the heat generated by the pair of plug pins.

本発明が解決しようとする課題は、プラグ本体の大型化を防止しながらも、複数の通電ピンでの発熱を精度よく検知できるプラグを提供することである。   The problem to be solved by the present invention is to provide a plug that can accurately detect heat generated by a plurality of energizing pins while preventing an increase in the size of the plug body.

本発明に係る形態のプラグは、前壁部及び前記前壁部より後方に突出する筒状の周壁部を有するプラグ本体と、それぞれの前端部が前記前壁部から前方に突出するように前記プラグ本体に収納される複数の通電ピンと、前記周壁部の両側にそれぞれ露設される長尺状の一対の接触片及び前記プラグ本体内において前記一対の接触片同士を連結する連結片を有する接地レールと、前記プラグ本体内において前記複数の通電ピンとそれぞれ間隔を空けて配置され前記複数の通電ピンの温度をそれぞれ検知する複数の温度検知素子と、を備える。前記連結片は、前記前壁部に対向する凹所を有するように曲げられた形状を有する。前記凹所は、前記前壁部と前記接地レールとの間に前記複数の温度検知素子を収容する収容スペースの少なくとも一部を構成する。   The plug according to the present invention includes a plug body having a front wall portion and a cylindrical peripheral wall portion protruding rearward from the front wall portion, and the front end portion protruding forward from the front wall portion. A plurality of energizing pins housed in the plug body, a pair of elongated contact pieces respectively exposed on both sides of the peripheral wall portion, and a grounding member for connecting the pair of contact pieces in the plug body A rail, and a plurality of temperature detection elements that are arranged at intervals from the plurality of energization pins in the plug body and detect temperatures of the plurality of energization pins, respectively. The connecting piece has a shape bent so as to have a recess facing the front wall. The recess constitutes at least a part of an accommodation space for accommodating the plurality of temperature detection elements between the front wall portion and the grounding rail.

本発明によれば、プラグ本体の大型化を防止しながらも、複数の通電ピンでの発熱を精度よく検知できるプラグを提供できる。   ADVANTAGE OF THE INVENTION According to this invention, the plug which can detect the heat_generation | fever with a several electricity supply pin accurately can be provided, preventing the enlargement of a plug main body.
