Patent number: 9218919Abstract: An electrical contactor has a pair of first terminals and a pair of second terminals. Each first terminal has a fixed member with at least one fixed electrical contact facing the other fixed member. The second terminals having back-to-back electrically-conductive movable arms with an electrically-insulating partitioning element there between. Each second terminal is associated with a different one of the first terminals, and has a movable electrical contact on the associated movable arm which faces the corresponding fixed contact. When the contacts close, contra-flowing current through the back-to-back movable arms produces a repulsive force between the movable arms increasing a force between the fixed and movable contacts.Type: GrantFiled: July 10, 2014Date of Patent: December 22, 2015Assignee: JOHNSON ELECTRIC S.A.Inventor: Richard Anthony Connell

Publication number: 20150318134Abstract: An electrical contactor has a first terminal having a first fixed contact; a second terminal having a second fixed contact; a first electrically-conductive movable arm in electrical communication with the first terminal and having a first movable contact thereon; a second electrically-conductive movable arm in electrical communication with the second terminal and having a second movable contact thereon, counter-opposed to the first moveable arm; and an actuator for moving the first and second moveable arms in opposing directions. The first moveable contact and the second fixed contact form a primary contact set, and the second moveable contact and the first fixed contact form a secondary contact set, first and second moveable arms thereby forming a current-sharing arm pair between first and second terminals.Type: ApplicationFiled: May 1, 2015Publication date: November 5, 2015Inventor: Richard Anthony Connell

Patent number: 9136068Abstract: An electrical contactor has a first terminal having an electrically-conductive fixed member with fixed contacts on opposite faces thereof, and a second terminal having a terminal body and an odd-number of electrically-conductive movable arms extending from the terminal body. Each movable arm has a movable contact thereon remote from the terminal body. The movable arms are arranged to oppose each other such that their movable contacts are on either side of the fixed member and aligned with the fixed contacts. The arrangement of the fixed member and the movable arms is such that, when the contacts close, current flowing through the movable arms produces a force which urges the movable arms towards each other thereby increasing a force between the fixed and movable contacts. The number of movable arms at each side of the fixed member is different.Type: GrantFiled: July 10, 2014Date of Patent: September 15, 2015Assignee: JOHNSON ELECTRIC S.A.Inventor: Richard Anthony Connell

Publication number: 20150228428Abstract: An electrical contactor has first and second terminals; a movable arm connected to the second terminal; and an actuator. The actuator has a magnet, first and second coils having a common connection and located either side of the magnet, a magnetic rocking armature pivotably attached between the coils and an actuation element connected to the first end of the rocking armature for actuating the movable arm. Driving the first coil causes a demagnetization of the first coil and a corresponding increase in magnetic flux in the second coil, latching the armature to the second coil and moving the movable arm in a first direction. Driving the second coil causes a demagnetization of the second coil and a corresponding increase in magnetic flux in the first coil, latching the rocking armature to the first coil and moving the movable arm in a second direction.Type: ApplicationFiled: February 13, 2015Publication date: August 13, 2015Inventor: Richard Anthony Connell

Publication number: 20150145621Abstract: An electrical contactor has a first terminal having a fixed member with at least one fixed electrical contact, a second terminal, and a busbar connected to the second terminal. Two conductive movable arms are connected to the busbar and have a contact thereon. One arm is biased-closed to contact the fixed electrical contact in the absence of a separating force, and the other arm is biased-open to be spaced away from the fixed electrical contact in the absence of a closing force. The first and second movable arms and the busbar are arranged so that, when the contacts close, contra-flowing current urges the movable arms towards the fixed member to increase a force between the contacts.Type: ApplicationFiled: November 26, 2014Publication date: May 28, 2015Inventor: Richard Anthony Connell

Patent number: 7049932Abstract: In a system for remotely controlling the supply of electric power to customer premises, each customer premises is fitted with a power-switching arrangement coupled to a paging receiver (5-1, 5-2, 5-3). A utility company supplying the electric power can input requests to a server (1), optionally via a terminal (2) or a network link (3). A software application running on the server generates a control instruction in response to a request and sends it to a paging service (4) for transmission over a paging network. When a paging message is received at one of said customer-premises paging receivers, if the control instruction is appropriately addressed the power-switching arrangement will put it into effect, for example to connect or reconnect the customer premises power supply.Type: GrantFiled: December 22, 2003Date of Patent: May 23, 2006Assignee: BLP Components, LimitedInventors: James French, William White, Michael Brading, Rizwan Ahmad, Richard Anthony Connell
