摘要： Sealed relays intended for high-voltage or high-power switching are enclosed in a herrnetically sealed plastic housing or jacket (11) capable of long-term maintenance of either a high vacuum or a pressurized insulating gas within the relay to suppress contact arcing during switching. The impermeable plastic housing eliminates need for conventional glass or ceramic contact enclosures, and enables use of inexpensive relays (71) in demanding applications.

摘要： A relay device utilizing a linear "impact break" method for contact break. An armature shaft has attached at one end a plunger situated at the base of the relay core. The armature has a terminal end portion at its other end. A spring provides a biasing force to maintain the plunger and armature shaft in open state. Resiliently mounted on the armature shaft adjacent its end opposite the plunger is a movable contact disc rotatable about the armature shaft for coming in contact with two stationary contacts in the closed state. The armature shaft towards its plunger end extends into an armature travel cavity. The armature shaft towards its movable contact end extends into a chamber open to the armature travel cavity. A movably mounted further spring is located about the armature shaft between the contact disc and a stop on the armature shaft. The further spring rotates upon its compression to rotate the contact disc to vary the position of contact during a plurality of closing operations. The terminal end portion extends beyond the contact disc upon closed state, and is accelerated by expansion of the further spring to impact the contact disc to provide the contacts open state. All moving parts of the relay are hermetically sealed from the outside atmosphere.

摘要： A relay device utilizing an angular "impact break" method to achieve contact break. A rotatable armature is pivotally mounted to one end of the relay while its other end remains separated from the relay pole center by a spring. A separate rotatable actuator, carrying a moving contact, is movably positioned atop the armature and pivoted at the same point where the armature is pivotally mounted. The armature responds to the electromagnetic effects caused by the excitation of the coil, and rotates downward towards the pole center. The actuator rotates along with the armature, due to a spring receptacle on the armature and an overtravel spring between the receptacle and actuator, until the moving contact connected to the actuator contacts the stationary contacts of the relay. After contact, the armature, continues its rotation while the actuator maintains the contact between the moving and stationary contacts. Upon de-energization, the armature rotates upward and away from the pole center and, before making contact with the actuator, acquires kinetic energy which is imparted upon the actuator upon impact with same. Impact force is sufficient to break the previously closed contacts and any welding which occurs between the contacts. The relay device further provides a number of features serving to reduce arcing, puddling and welding.
摘要翻译：一种利用角度“冲击断裂”方法实现接触断裂的中继装置。可旋转电枢枢转地安装在继电器的一端，而其另一端通过弹簧与继电器极中心保持分离。承载移动触点的单独的可旋转致动器可移动地定位在电枢顶部并且枢转在电枢枢转地安装的相同点处。电枢响应于由线圈的激励引起的电磁效应，并向着磁极中心向下旋转。由于电枢上的弹簧座和插座与致动器之间的超行程弹簧，致动器与电枢一起旋转，直到连接到致动器的可动触头与继电器的固定触点相接触。接触后，电枢继续旋转，同时致动器保持移动和静止触点之间的接触。在断电时，电枢向上旋转并离开极点，并且在与致动器接触之前获得在与其相撞时施加在致动器上的动能。冲击力足以破坏先前闭合的触点和触点之间发生的任何焊接。继电器装置还提供了许多用于减少电弧，搅拌和焊接的特征。
