Description

スイッチギヤSwitchgear
　この発明は、例えば固定側端子を含む固定側機器と可動側端子を含む可動側機器とはそれぞれ独立して製作され、それぞれの固定側機器と可動側機器とが組み込まれて製作されるスイッチギヤに関するものである。 In the present invention, for example, a fixed device including a fixed terminal and a movable device including a movable terminal are manufactured independently, and each fixed gear and a movable device are assembled and manufactured. It is about.
　従来のスイッチギヤは、固定接触部である固定側電極と、可動接触部である可動側電極が互いに対向して配設されている。可動側電極内には可動接触子が摺動自在に挿入されている。この可動接触子は直線的に移動して、固定側電極と可動側電極とを開閉するものである。 In a conventional switchgear, a fixed side electrode that is a fixed contact portion and a movable side electrode that is a movable contact portion are arranged to face each other.

　上述した従来のスイッチギヤは、可動接触子が固定側電極に投入される時、両者に芯ずれがあると、可動接触子は傾斜した状態で投入動作を行うことになる。この結果、摺動する可動接触子と可動側電極との接触が不安定となる。 In the conventional switchgear described above, when the movable contact is inserted into the fixed side electrode, if there is a misalignment between the two, the movable contact performs the closing operation in an inclined state. As a result, the contact between the sliding movable contact and the movable electrode becomes unstable.
　電力需要が増大する近年、スイッチギヤには優れた信頼性が求められている。そのため従来では、可動接触子及び固定側電極には芯ずれが起きないよう、可動接触子と固定側電極との同軸度の位置合せを調整治具等で極めて高い精度で調整を行っている。しかしながら、このような緻密な調整作業は多大の時間を要し、コスト高騰の要因となっていた。 In recent years, when power demand is increasing, switch gears are required to have excellent reliability. Therefore, conventionally, alignment of the coaxiality between the movable contact and the fixed side electrode is adjusted with extremely high accuracy using an adjustment jig or the like so that misalignment does not occur between the movable contact and the fixed side electrode. However, such precise adjustment work takes a lot of time and has been a cause of cost increase.
　この発明は、上記のような課題を解決するためになされたものであり、その目的は、簡単な構成で固定側端子と可動側端子との同軸度調整を省力化し、低コストの実現及び信頼性の向上を図ることができるスイッチギヤを提供するものである。 The present invention has been made to solve the above-described problems, and an object of the present invention is to save labor for adjusting the degree of coaxiality between the fixed-side terminal and the movable-side terminal with a simple configuration, thereby realizing low-cost realization and reliability. The switchgear which can aim at the improvement of property is provided.
　この発明に係わるスイッチギヤは、固定側端子を含む固定側機器と可動側端子を含む可動側機器とはそれぞれ独立して製作され、それぞれの固定側機器と可動側機器とが組み込まれて製作されるスイッチギヤにおいて、前記固定側端子の先端部は球面状に形成され、前記可動側端子の先端部は球面状に形成され、前記固定側端子および前記可動側端子の各先端部の円周上をまたいで所定の間隔で複数個配置され、球面状にそれぞれ形成された固定側接触部および可動側接触部がそれぞれ前記固定側端子および前記可動側端子と接触する導電性金属からなる接触子片と、前記接触子片の固定側に配置され、前記接触子片と前記固定側端子との接触圧を保持する固定側環状押圧体と、前記接触子片の可動側に配置され、前記接触子片と前記可動側端子との接触圧を保持する可動側環状押圧体とを設けたものである。 The switchgear according to the present invention is manufactured independently of the fixed-side device including the fixed-side terminal and the movable-side device including the movable-side terminal, and is manufactured by incorporating each fixed-side device and the movable-side device. In the switchgear, the distal end portion of the fixed side terminal is formed in a spherical shape, the distal end portion of the movable side terminal is formed in a spherical shape, and is on the circumference of each distal end portion of the fixed side terminal and the movable side terminal. A plurality of contact pieces made of conductive metal, each of which has a fixed side contact portion and a movable side contact portion that are arranged in a spherical shape and are in contact with the fixed side terminal and the movable side terminal. A fixed-side annular pressing body that is disposed on a fixed side of the contact piece, and that holds a contact pressure between the contact piece and the fixed-side terminal, and is disposed on a movable side of the contact piece. Piece and said movable It is provided with a movable side annular pressing body that holds the contact pressure between the terminals.
