20100307893 | INSULATING SWITCHING ROD - An insulating switching rod has a drive element for initiating a drive movement in an electrical contact system of a switching device and for producing a contact force when the contact system is in the closed state. The system further includes a clamping apparatus for the drive element of the switching rod in order to maintain the contact force. The object is to produce a greater contact force with a compact design and ensure constant spring characteristics as well as low wear over the entire useful life. For that purpose, the switching rod and the drive element can be directly or indirectly connected to one another by way of a plug and latching connection. | 12-09-2010 |
20130118868 | TERMINAL ASSEMBLY FOR A POWER SWITCH IN TENSION SPRING TECHNOLOGY - A terminal assembly is disclosed for a power switch for electrical contact to terminal points which are designed to receive electrical lines. The terminal assembly of at least one embodiment is arranged on a tension-spring-based power switch. | 05-16-2013 |
20140131178 | Structure For Limiting Back-Travel Of Interrupters On Circuit Breakers - Holding structure includes a gear rack member for coupling with an object for movement therewith. The gear rack member includes a set of a teeth and a cam profile surface. A latch is associated with the set of teeth so as to engage and disengage the teeth. A cam follower is fixed to the latch to engage the cam profile surface thereby defining the engaged or disengaged position of the latch with respect to the teeth. A spring provides torque on the latch. The holding structure is constructed and arranged such that during movement of the object in an intended direction, the latch engages the teeth and is held in the engaged position by the spring so as to stop any movement of the object in a direction that is opposite the intended direction, otherwise, the spring is constructed and arranged to hold the latch in the disengaged position. | 05-15-2014 |
20140360850 | POWER SWITCHGEAR - Each outermost part of fixed-side connection conductors, fixed-side fixed contacts, movable-side fixed contacts, and movable-side connection conductors are placed outside of an outermost diameter of a fixed-side conductor and a movable-side conductor, as viewed from an axis line of the fixed-side conductor and the movable-side conductor as a center. This arrangement provides a power switchgear that can diminish mutual effects of currents among conduction parts to suppress decrease in a current-carrying capacity for each of the conduction parts and to increase a current-carrying capacity for a total of the conduction parts, without increasing the size of the switchgear. | 12-11-2014 |
200500290 | Switch locks plug | 1 |
20150380878 | Bus Plug Lockout Devices and Related Apparatus and Methods - An apparatus for locking out an elevated bus plug includes an elongated member, a lockout device at a distal end portion of the elongated member and an actuator at a proximal end portion of the elongated member. The lockout device includes a housing, a channel in the housing that is sized and configured to receive a handle of the bus plug and a handle engagement mechanism connected to the housing. The handle engagement mechanism is configured to engage a handle of the bus plug that has been received in the channel responsive to actuation of the actuator. | 12-31-2015 |
200500300 | Dual interlock | 1 |
20110203908 | MECHANICAL INTERLOCK OF A LEVER OPERATED RECEPTACLE WITH A SHAFT OPERATED SWITCH - A mechanical interlock of a lever operated receptacle with a shaft operated switch is disclosed and provides mechanically interlocked electrical service to cord-connected equipment such as wheeled gantries, vehicles docked at port terminals, heavy manufacturing, and mining equipment. The power transmission safety system locks a plug into a receptacle until a main power switch has been disengaged and a grounding switch has been engaged. Only if the receptacle is switched off and grounded will the receptacle allow a plug to be inserted. The power transmission safety system is mechanically prohibited from being engaged or ungrounded until a plug has been inserted into the receptacle and locked into place. To again unlock and remove the plug from the receptacle, the power transmission safety system must be deactivated and grounded. | 08-25-2011 |
