    摘要： An autosecuring solenoid utilizes an interposing device that restrains the solenoid plunger when the solenoid is de-energized and/or energized, effectively preventing undesired movement of the plunger. When a voltage is applied across the coil, the flowing current creates an magnetic field. This field causes the plunger to slide within the solenoid cavity, unless restrained. This field also causes displacement of a movable magnet in the interposing device. The direction of motion of the movable magnet will depend on the magnetic field orientation of the movable magnet with respect to the magnetic field. Thus, the interposing device may move either toward or away from the plunger. Additionally, if using two interposing devices, one device could move away from the plunger and the second device could move toward the plunger. The second interposing device could even permit the plunger to move until the second interposing device engaged a recess or notch in the plunger. The first and/or second interposing devices may be restored by attraction between the movable magnet and the plunger or top of the interposing housing when the solenoid is de-energized. Alternatively, a second small magnet, spring, or other device in the housing of the interposing device returns the movable magnet to its desired position when the solenoid is de-energized.

    摘要翻译： 自动保护电磁阀利用插入装置，当螺线管断电和/或通电时，该插入装置限制螺线管柱塞，有效地防止柱塞的不期望的运动。 当线圈上施加电压时，流过的电流产生磁场。 该场导致柱塞在螺线管腔内滑动，除非受到限制。 该场还引起插入装置中的可移动磁体的位移。 可动磁铁的运动方向取决于可动磁铁相对于磁场的磁场取向。 因此，插入装置可以朝向或远离柱塞移动。 另外，如果使用两个插入装置，一个装置可以移动离开柱塞，并且第二装置可以朝向柱塞移动。 第二插入装置甚至可以允许柱塞移动直到第二插入装置接合柱塞中的凹部或凹口。 当螺线管断电时，第一和/或第二插入装置可以通过可移动磁体和柱塞之间的吸引力或插入壳体的顶部来恢复。 或者，中间装置的壳体中的第二小磁体，弹簧或其他装置在螺线管断电时将可移动磁体返回到其期望的位置。

    摘要： A locking device (6) which is provided in particular for vacuum contactors prevents an unintentional closing of the contact due to arbitrary mechanical influence as long as the electromagnetic actuator (1) is not excited. This takes place by means of a blocking lever (10), which is adjustably attached to a bearing block (7) between both of the parallel-mounted coils (3) of the actuator (1). A particularly rapid response of the blocking lever (10) is achieved by means of an acute-angled blade that sticks out, which is designed as an extension of the midsection (17) of the U- or C-shaped principal body of the blocking lever (10).

    摘要： A latching relay includes a housing and a coil secured to the housing. An armature is electromagnetically coupled to the coil such that current to the coil biases the armature to a first position. A spring is coupled to the armature to bias the armature to a second position. The relay includes a switch which includes a movable contact coupled to the armature such that the switch is in a first state when the armature is in the first position and the switch is in a second state when the armature is in the second position. A magnet is movable in the housing between a blocking position, in which the magnet acts as a mechanical block to prevent the armature from moving to the second position, and an unblocking position, in which the magnet allows the armature to move to the second position. The magnet is electromagnetically coupled to the coil such that current through the coil in a first direction moves the magnet to the blocking position and current through the coil in a second direction moves the magnet to the unblocking position.

    摘要： The trip mechanism of a molded case type circuit breaker is actuated by a plunger that is integral with and axially extends from the end of a reciprocally-movable core member of a solenoid mounted within the breaker housing. The free end of the plunger strikes the trip bar of the breaker when the solenoid is energized in response to a current overload condition in the circuit being protected. The solenoid core member and plunger are mechanically locked in NO-TRIP position by spring-biased keeper means that is automatically released from its "lock" position by the magnetic field generated by the solenoid coil when it is energized. A spring automatically resets the trip-actuating assembly when the current-overload condition has been corrected and the solenoid coil is deenergized. The trip-actuating assembly is not only compact, reliable and inexpensive but is inherently adapted to withstand severe mechanical shocks and impacts, such as those encountered aboard naval vessels, and is thus especially suited for use in circuit breakers that will be employed to protect electrical circuits and equipment subjected to such rough service conditions.

    摘要： An actuating device for a vacuum switching tube has a connecting element which can be connected to an electric contact of the vacuum switching tube, an electromagnetic actuating device for displacing the connecting element between a first and a second position, and a retaining yoke, relative to which the connecting element can be displaced and has a first magnetic element. The first magnetic element generates a first and a second magnetic circuit in the retaining yoke. The actuating device further has a ferromagnetic retaining anchor, which is arranged on the connecting element. The retaining anchor is located in the first position of the connecting element in the first magnetic circuit and in the second position of the connecting element in the second magnetic circuit. The connecting element is held in the first and in the second position by a respective magnetic force between the retaining yoke and the retaining anchor.
