연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An apparatus includes an electrical assembly (e.g., a contactor) configured to be inserted into an enclosure. The electrical assembly includes at least one first contact configured to mate with at least one second contact disposed in an enclosure when the contactor assembly is inserted in the enclosure. The apparatus further includes an ejector mechanism including at least one pivoting member attached to the electrical assembly and configured to pivot about a point of attachment to the electrical assembly to apply a force to a surface of the enclosure and thereby cause movement of the electrical assembly within the enclosure. The movement of the electrical assembly caused by the ejector mechanism may disengage the at least one first contact from the at least one second contact. The electrical assembly may include a wheeled undercarriage and the at least one pivoting member may be attached to the undercarriage.

1. An apparatus for installation in and removal from an enclosure having at least one first contact, the apparatus comprising: an electrical assembly having a wheeled undercarriage and configured to be rolled on a horizontal wall of the enclosure, the electrical assembly comprising at least one second contact configured to mate with the at least one first contact when the electrical assembly is rolled into the enclosure; andan ejector mechanism comprising first and second pivoting members attached to the undercarriage near respective first and second sides thereof and configured to apply a force to a surface of the enclosure and a bar attached to the first and second pivoting members near respective first and second ends of the bar, wherein pressure applied to the bar causes the first and second pivoting members to pivot and thereby cause movement of the electrical assembly by movement of the wheeled undercarriage within the enclosure. 2. The apparatus of claim 1, wherein movement of the electrical assembly caused by the ejector mechanism disengages the at least one second contact from the at least one first contact. 3. The apparatus of claim 1, wherein the first and second pivoting members are configured to pivot from a first position to a second position to engage the surface of the enclosure in response to a force applied thereto, and wherein the ejector mechanism is spring loaded to cause the first and second pivoting members to return to the first position when the force is removed. 4. The apparatus of claim 1, wherein the undercarriage has a front edge that faces outward from the enclosure when the electrical assembly is inserted in the enclosure, wherein the first and second pivoting members are attached to the undercarriage near the front edge, and wherein the bar is disposed outward of the front edge. 5. The apparatus of claim 4, wherein the enclosure comprises a floorstanding cabinet, wherein the surface of the enclosure engaged by the first and second pivoting members is located near a front edge of a floor-facing wall of the cabinet. 6. The apparatus of claim 1, wherein the at least one first contact comprises a conductive member extending toward the electrical assembly in a direction of the movement of the electrical assembly and wherein the at least one second contact comprises a stab configured to receive the conductive member when the electrical assembly is inserted in the enclosure. 7. The apparatus of claim 1, wherein the electrical assembly comprises a switching device. 8. The apparatus of claim 7, wherein the electrical assembly comprises a contactor assembly. 9. An apparatus for installation in and removal from an enclosure, the apparatus comprising: an electrical contactor;a wheeled undercarriage configured to support the electrical contactor and to roll along an upper surface of a horizontal wall of the enclosure to facilitate insertion of the electrical contactor into the enclosure; andan ejector mechanism comprising first and second pivoting members attached to the undercarriage and configured to engage the surface of the enclosure and a bar attached to the first and second pivoting members, wherein pressure applied to the bar causes the first and second pivoting members to pivot and apply a force to the surface of the enclosure and thereby cause movement of the undercarriage and the electrical contactor within the enclosure. 10. The apparatus of claim 9, wherein the first and second pivoting members are configured to pivot from a first position to a second position to engage the surface of the enclosure in response to a force applied thereto, and wherein the ejector mechanism is spring loaded to cause the first and second pivoting members to return to the first position when the force is removed. 11. The apparatus of claim 9, wherein the undercarriage has a front edge that faces outward from the enclosure when inserted in the enclosure, and wherein the first and second pivoting members are attached to the undercarriage near the front edge. 12. The apparatus of claim 9, wherein the electrical contactor comprises at least one first contact configured to engage at least one second contact within the enclosure when the electrical contactor and the undercarriage are inserted in the enclosure, and wherein movement of the undercarriage and the electrical contactor by the ejector mechanism disengages the at least one first contact from the at least one second contact. 13. An ejector for extracting an electrical assembly from an enclosure, the ejector comprising: first and second pivoting members configured to be attached to a wheeled undercarriage that supports the electrical assembly and facilitates rolling of the electrical assembly along an upper surface of a horizontal wall of the enclosure; anda force receiving member coupled to the first and second pivoting members and configured to pivot the first and second pivoting members about points of attachment to the wheeled undercarriage that supports the electrical assembly to apply a force to a surface of the enclosure and thereby cause movement of the electrical assembly within the enclosure. 14. The ejector of claim 13, wherein the force receiving member comprises a bar attached to the first and second pivoting members at respective first and second ends of the bar, and wherein pressure applied to the bar causes the first and second pivoting members to pivot. 15. The ejector of claim 14, wherein the undercarriage has a front edge that faces outward from the enclosure when inserted in the enclosure, and wherein the first and second pivoting members are configured to be attached to the undercarriage near the front edge. 16. The apparatus of claim 1, wherein the ejector mechanism is configured to be engaged by a foot of an operator to enable movement of the at least one pivoting member with the operator's body weight. 17. The apparatus of claim 11, wherein the ejector mechanism is configured for engagement of the bar by a foot of an operator to enable actuation of the ejector mechanism with the operator's body weight. 18. The ejector of claim 15, wherein the ejector is configured for engagement of the bar by a foot of an operator to enable actuation of the ejector with the operator's body weight.
