Description
本発明は、複数の給電ピンと接地ピンとを有するプラグを受けるためのソケットに関するものである。 The present invention relates to a socket for receiving a plug having a plurality of power supply pins and a ground pin.
特許文献１は、３極プラグと２極プラグとの２種類のプラグが接続されるソケットを開示している。このソケットは、３極プラグの３つのピン、２極プラグの２つのピンが貫通するピン孔、各ピンを受けるピン受け、外部の電線が結合される金属製の端子台を備える。ピン受けとこれに対応する端子台は、各ピン孔の延長線上、すなわち、ソケットの高さ方向にそって並んで配置されており、各ピン孔に端子台が露出している。端子台には電線を結合するための端子ねじが備えられ、端子ねじと端子台の上壁との間で電線を保持する。このため、端子ねじの締め付けに伴う応力が端子台の上壁に作用する。この上壁がピン孔に露出しているため、繰り返しプラグの脱着が行われる際に、ピンが上壁に衝突して上壁を傷つける可能性がある。或いは、間違って棒をピン孔に差し込んだりすると、この棒で端子台の上壁を傷つける可能性がある。端子台が傷つけられると表面保護膜がはがれて、錆が生じることになるが、端子ねじの締め付けによる応力を受ける上壁に錆が生じると、応力腐食が助長されて、端子台の破損につながる虞がある。 Patent Document 1 discloses a socket to which two types of plugs, a three-pole plug and a two-pole plug, are connected. This socket includes three pins of a three-pole plug, a pin hole through which two pins of the two-pole plug pass, a pin receiver that receives each pin, and a metal terminal block to which an external electric wire is coupled. The pin receiver and the corresponding terminal block are arranged along the extension line of each pin hole, that is, along the height direction of the socket, and the terminal block is exposed in each pin hole. The terminal block is provided with a terminal screw for coupling the electric wire, and holds the electric wire between the terminal screw and the upper wall of the terminal block. For this reason, the stress accompanying tightening of the terminal screw acts on the upper wall of the terminal block. Since the upper wall is exposed in the pin hole, the pin may collide with the upper wall and damage the upper wall when the plug is repeatedly attached and detached. Alternatively, if the rod is mistakenly inserted into the pin hole, the rod may damage the upper wall of the terminal block. If the terminal block is damaged, the surface protection film will be peeled off and rust will be generated. However, if rust is generated on the upper wall that receives stress due to tightening of the terminal screw, stress corrosion will be promoted and the terminal block will be damaged. There is a fear.

A leg piece 70 extends downward from one coupling piece 56, and a power supply insertion piece 53 extends outward from the lower end of the leg piece 70. The feeding plug 53 is elastically contacted with the lower surface of the upper wall within the metal frame of the feeding terminal block 57 and is electrically connected to the feeding terminal block 57. A hooking piece 58 is formed at the tip of the power supply insertion piece 53, and the hooking piece 58 engages with the edge of the upper wall of the power supply terminal block 57, whereby the composite pin receiver 50 and the power supply terminal block 57 are temporarily connected. It is possible to be assembled in the case 20 in a stopped state. When the power supply line is coupled to the power supply terminal block 57 with the terminal screw 571, the power supply insertion piece 53 is pressed against the upper wall of the terminal block by the tightening force of the terminal screw 571, so that the composite pin receiver 50 and the power supply terminal block 57 are pressed. And are firmly fixed.
接地ピン受け６０は、図４に示すように、一対の弾性片６４がその一端で結合片６６により結合された構造を有し、弾性片６４の間に接地ピン２を受ける第３ポケット６１が形成される。結合片６６から外方に延出する接地差込片６３が接地端子台６７の上壁下面に圧接されて両者の電気接続がなされる。接地差込片６３の先端に形成した引っ掛け片６８が上壁の端縁に係合することで、接地ピン受け６０と接地端子台６７とが仮止めされた状態で、ケース２０内に組み込まれることを可能にしている。端子ねじ６７１でアース線を接地端子台６７に結合した時には、端子ねじ６７１の締め付け力により、接地差込片６３が接地端子台６７の上壁に押し付けられることで、接地ピン受け６０と接地端子台６７とが強固に固定される。 As shown in FIG. 4, the ground pin receiver 60 has a structure in which a pair of elastic pieces 64 are coupled by a coupling piece 66 at one end thereof, and a third pocket 61 that receives the ground pin 2 is interposed between the elastic pieces 64. It is formed. A grounding insertion piece 63 extending outward from the coupling piece 66 is pressed against the lower surface of the upper wall of the grounding terminal block 67 to make electrical connection therebetween. The hook piece 68 formed at the tip of the ground plug 63 is engaged with the edge of the upper wall, so that the ground pin receiver 60 and the ground terminal block 67 are temporarily fixed and assembled into the case 20. Making it possible. When the ground wire is coupled to the ground terminal block 67 with the terminal screw 671, the ground insertion piece 63 is pressed against the upper wall of the ground terminal block 67 by the tightening force of the terminal screw 671. The base 67 is firmly fixed.
このように、各ピン受け５０、６０はその一端から延出する差込片５３、６３で対応する端子台５７、６７に電気的に接続されて、各ピン受け５０、６０とこれに対応する端子台５７、６７とが、ケース２０内の２次元平面内、すなわち、ケース２０の高さ方向と直行する平面内で横に並んで配置される。そして、それぞれの端子台５７、６７がカバープレート１０のピン孔（１１、１２、１３）と横にずれることになり、ソケットの薄型化が達成されると共に、端子台（５７、６７）をピン孔（１１、１２、１３）から隠すことができる。この結果、ピン孔（１１、１２、１３）から挿入される給電プラグのピンの先端、あるいは、異物が端子台（５７、６７）の上面に及ぶことがなく、端子台（５７、６７）をこれらの部材との接触による損傷による腐食から保護して、長期に亘る品質の安定性
が計られる。
