供するにある。[Detailed description of the invention] The present invention has a plurality of plug blades 2, 2, .
Connect the conductor part of cord 3 to ..., and connect this plug blade 2, 2.
A surrounding wall 5 integral with the base body 1 is provided around the outer periphery of the connecting portion between the conductor portion of the cord 3 and a separating wall 6 is provided between the connecting portions.
The upper end of the surrounding wall 5 and the upper end of the separating wall 6 are located above the plug blade 2 and the connection part between the plug blade 2 and the conductor part of the cord 3, and the plug blades 2, 2... The purpose of this plug is to cover the outer periphery of the base 1 except for the insertion tip with a flexible synthetic resin outer skin 4, and to fill the surrounding wall with the flexible synthetic resin together with the synthetic resin outer skin 4. The object of the present invention is to provide a highly heat-resistant plug that can be used safely against heat generation caused by loose contact between an outlet and a plug blade, for example.

変形にて栓刃の位置が狂ったりしやすい欠点があった。In conventional integrally molded plugs, the area around the connection between the plug blade and the conductor part of the cord is directly covered with a coating resin such as polyvinyl chloride, so for example, heat generation due to loose contact between the outlet and the plug blade can occur. The coating resin easily softens or melts, and if the plug is inserted or removed in that state, the plug blade tends to fall out of the coating resin or become misaligned due to deformation of the coating resin. .
本考案はかかる従来の欠点を解消せんとするもので、以
下添付図により詳述する。The present invention is intended to solve these conventional drawbacks, and will be explained in detail below with reference to the accompanying drawings.
基体１は熱硬化性樹脂、耐熱硬質熱可塑性樹脂等の硬度
、耐熱性の良い材料で形成されるもので、複数個の栓刃
２，２が貫挿保持されており、この栓刃２，２とコード
３の導体部とを基体１内で連結しである。The base body 1 is made of a material with good hardness and heat resistance, such as a thermosetting resin or a heat-resistant hard thermoplastic resin, and has a plurality of plug blades 2, 2 inserted therethrough and held therein. 2 and the conductor portion of the cord 3 are connected within the base body 1.
この基体１の外周には上記栓刃２とコード３の導体部と
の接続部を囲む囲壁５が一体に施され、更に同接続部間
を分離する隔離壁６が一体に施される。A surrounding wall 5 surrounding the connecting portion between the plug blade 2 and the conductor portion of the cord 3 is integrally provided on the outer periphery of the base body 1, and a separating wall 6 is further integrally provided to separate the connecting portion.
この場合、栓刃２の基部は基体１の囲壁５と隔離壁６と
にて構成された凹所底面に密着し、また囲壁５と隔離部
６とはいずれも栓刃２とコード３の導体部との接続部が
隠れるだけの高さを有している。In this case, the base of the plug blade 2 is in close contact with the bottom of the recess formed by the surrounding wall 5 and the separating wall 6 of the base 1, and both the surrounding wall 5 and the separating part 6 are connected to the conductor of the plug blade 2 and the cord 3. The height is high enough to hide the connection part with the other parts.
また更に栓刃２の基部両側には保持板７，７が設けられ
、この保持板７，７の相対向する面より突設された突起
８，８・・・・・・にて栓刃２の基部を両側より挟持す
るようにしである。Further, retaining plates 7, 7 are provided on both sides of the base of the plug blade 2, and projections 8, 8, . The base of the holder is held between both sides.

るものである。However, a flexible synthetic resin outer skin 4 such as soft vinyl chloride resin is insert molded around the entire outer periphery of the base 1 of the lever except for the insertion tip of the plug blade 2, and is integrally covered with the outer periphery. In this case, the flexible synthetic resin is filled into the surrounding wall 5 together with the synthetic resin outer skin 4.

なり作業性よく行ない得る利点がある。In the present invention, a plurality of plug blades are inserted and held in a base made of a material with good heat resistance, so a synthetic resin outer cover covering the base and a flexible Even if the plastic synthetic resin softens and melts due to heat, the plug blade remains firmly in place. It has the advantage of being safe to use without causing the position of the plug blade to go out of order, and also when coating the base with a synthetic resin outer cover, the conductor part of the cord can be connected to the plug blade inserted through the base and held. Therefore, the coating process is performed while the plug blade to which the conductor part of the cord is connected is temporarily fixed to the base body, which has the advantage that workability can be improved.

きる利点がある。Moreover, in the present invention, a surrounding wall integral with the base body is provided around the outer periphery of the connecting portion, and a separating wall is provided between the connecting portions, and the upper end of the surrounding wall and the upper end of the separating wall are connected to the plug blade and the conductor portion of the plug blade and the cord. Since the base of the plug blade is hidden by the surrounding wall and is isolated from each other by the separating wall, the synthetic resin outer skin and the synthetic resin Even if the flexible synthetic resin filled in the surrounding wall together with the outer skin softens and melts due to heat generation, the clamping force when gripping the plug by hand will not be transmitted directly to the base of the plug blade, and the blade will be tilted. It has the advantage of preventing deformation and being safe to use.
