Description
本考案は、ノーヒューズブレーカーの構造に関するものであり、特に電気スイッチ機能を兼ね備えたノーヒューズブレーカーに関するものである。 The present invention relates to the structure of a no-fuse breaker, and more particularly to a no-fuse breaker having an electric switch function.
電気スイッチ機能を兼ね備えたノーヒューズブレーカーには通常、オーバーロード防止機能が備
えられており、その原理は、熱膨張係数の異なるバイメタルプレートが可動コンタクトの弾性プレ
ートとして用いられ、ブレーカーにおけるスイッチ部材が押圧されて導通状態となった時、そのス

から離れ、電源が瞬断される。また、ブレーカーがON状態、即ち導通状態の時にオーバーロード
が発生した場合は、バイメタルプレートが熱変形し可動コンタクトが固定コンタクトから即座に離
れて、スイッチ部材が復位し電源が瞬断される。故に、オーバーロードによる電気装置の破損を防
止することができる。
前記バイメタルプレートをオーバーロード防止手段として使用するブレーカーは、数多く設計され、それらのブレーカーにおけるスイッチ部材の殆どが直接に中空のカバー体上に枢設される構成を採用しており、また、該ボタンの一端には成形或いは接合方式により突ブロックが設けられる。これにより、スイッチ部材が導通状態の時、該突ブロックがバイメタルプレートを下方へ押圧して、二つのコンタクトを接触させ導通状態とする。
A no-fuse breaker that also has an electric switch function is usually provided with an overload prevention function.The principle is that a bimetal plate having a different coefficient of thermal expansion is used as an elastic plate of a movable contact, and the switch member in the breaker is pressed. When the switch is turned on and the switch member is pressed, the movable contact on the bimetal plate and the fixed contact on the pin of the lead come into contact with each other to be in a conductive state. Conversely, when the switch member is pressed to be in a non-conductive state, the bimetal plate is immediately lifted upward, the movable contact is separated from the fixed contact, and the power supply is momentarily interrupted. If an overload occurs when the breaker is in the ON state, that is, in the conductive state, the bimetal plate is thermally deformed, the movable contact is immediately separated from the fixed contact, the switch member is restored, and the power is cut off instantaneously. Therefore, breakage of the electric device due to overload can be prevented.
Many breakers using the bimetal plate as the overload prevention means are designed, and adopt a configuration in which most of the switch members in those breakers are pivoted directly on a hollow cover body. A protruding block is provided at one end by molding or joining. Thus, when the switch member is in the conductive state, the protruding block presses the bimetal plate downward, and the two contacts are brought into contact to make the conductive state.
しかし、前記のような、直接に中空のカバー体上に枢設させる方式によるスイッチ部材は、各メーカーにより形状が異なることから、スイッチ部材に応じてその都度型を作製する必要があるので、製造コスト及び製造時間の増加につながる。 However, since the shape of the switch member that is directly pivoted on the hollow cover body as described above is different depending on the manufacturer, it is necessary to manufacture a mold in accordance with the switch member each time. This leads to increased costs and manufacturing time.
本考案は、スイッチ部材(10)、ベース(20)及び筐体(30)を有するブレーカーであって、
ベース(20)は、筐体(30)に枢設されると共に、筐体(30)におけるバイメタルプレートと対応するように押圧ブロック(26)が突設され、スイッチ部材(10)は、ベース(20)の押圧ブロック(26)が形成されない側に係合される係合部(13)を備えることを特徴とするノーヒューズブレーカー、を提供する。
The present invention is a breaker having a switch member (10), a base (20) and a housing (30),
The base (20) is pivotally mounted on the housing (30), and a pressing block (26) is provided so as to correspond to the bimetal plate on the housing (30). 20) A non-fuse breaker provided with an engagement portion (13) engaged with the side where the pressing block (26) is not formed.
本考案は上述したように、スイッチ部材、ベース及び筐体を有するブレーカーであって、ベースは、筐体に枢設されると共に、筐体におけるバイメタルプレートと対応するように押圧ブロックが突設され、スイッチ部材は、ベースの押圧ブロックが形成されない側に係合される係合部を備える構成であるので、同一のベースに異なる形状のスイッチ部材を自由に組み合わせることができる。故に、ベースの大量生産が可能になると共に、コストダウンも図れる。 As described above, the present invention is a breaker having a switch member, a base, and a housing, wherein the base is pivotally mounted on the housing, and a pressing block is protruded to correspond to a bimetal plate in the housing. Since the switch member has an engagement portion that is engaged on the side of the base where the pressing block is not formed, switch members having different shapes can be freely combined with the same base. Therefore, the base can be mass-produced and the cost can be reduced.
以下、添付図面を参照して本考案の好適な実施の形態を詳細に説明する。

図1及び図2に示すように、本考案のノーヒューズブレーカーは互いに組み合わされるスイッチ部材(10)、ベース(20)及び筐体(30)を有し、その内のベース(20)は四辺を有するケース状であり、その内部に中空の収容空間(21)が形成され、収容空間(21)における一方の側壁上に二つの第一係合孔(22)が形成されると共に、他方の側壁上に少なくとも一つの第二係合孔(23)が形成され、更に、該二つの第一係合孔(22)の間における、収容空間(21)の内壁に、第一係合孔(22)の軸方向と同様に内側へ垂直に伸びる凸部(24)が設けられると共に、ベース(20)における第一係合孔(22)が形成される両側壁にそれぞれ外側へ伸びる枢設ブロック(25)が設けられ、それにより、ベース(20)を筐体(30)の側壁に枢設する。また、前記ベース(20)の一端に、筐体(30)内における二つの金属弾性部材の自由端の上方と対応する押圧ブロック(26)が突設され、その二つの金属弾性部材が押圧されることにより導通状態となる。尚、押圧ブロック(26)と二つの金属弾性部材との切換動作は周知の技術であるので、その説明は省略する。
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a perspective view showing a state in which the switch member and the base of the no-fuse breaker according to the present invention are combined with a housing. FIG. 4 is an exploded view showing different switch members of the no-fuse breaker according to the present invention. It is a perspective view.
As shown in FIGS. 1 and 2, the no-fuse breaker of the present invention has a switch member (10), a base (20) and a housing (30) combined with each other, and the base (20) has four sides. A hollow housing space (21) is formed therein, two first engagement holes (22) are formed on one side wall of the housing space (21), and the other side wall is formed. At least one second engagement hole (23) is formed on the inner wall of the storage space (21) between the two first engagement holes (22). ) Are provided in the same manner as in the axial direction, and a protrusion (24) extending vertically inward is provided, and a pivoting block (24) extending outward on both side walls of the base (20) where the first engagement holes (22) are formed. 25), whereby the base (2 ) Is pivotally coupled to the side wall of the housing (30). At one end of the base (20), a pressing block (26) corresponding to a position above the free ends of the two metal elastic members in the housing (30) is projected, and the two metal elastic members are pressed. As a result, a conductive state is obtained. The switching operation between the pressing block (26) and the two metal elastic members is a well-known technique, and a description thereof will be omitted.
また、前記スイッチ部材(10)にベース(20)の側に開口するカバー体(11)が設けられ、そのカバー体(11)におけるベース(20)側の対向位置それぞれ係合板(12)が延設されると共に、二つの係合板(12)上にそれぞれ第一係合孔(22)及び第二係合孔(23)と対応する係合部(13)が設けられ、これにより、図3に示すようにスイッチ部材(10)がベース(20)に固定されると共に、スイッチ部材(10)が固定されたベース(20)が筐体(30)に枢設される。そして、スイッチ部材(10)が切換えられると、それにベース(20)が連動し、押圧ブロック(26)により二つの金属弾性部材が押圧される。更に、スイッチ部材(10)の係合板(12)における、収容空間(21)の凸部(24)と対応する位置にスリット(14)が形成され、これにより、スイッチ部材(10)とベース(20)との間の接合強度を高められる。 The switch member (10) is provided with a cover body (11) that opens toward the base (20). In addition, an engagement portion (13) corresponding to the first engagement hole (22) and the second engagement hole (23) is provided on each of the two engagement plates (12). As shown in FIG. 7, the switch member (10) is fixed to the base (20), and the base (20) to which the switch member (10) is fixed is pivotally mounted on the housing (30).
