Abstract:
The present disclosure relates to a device for limiting movement of a movable part in electrical equipment and the electrical equipment comprising the same. The limiting device comprises: a stopper (10) provided in a moving path of the movable part (20) and configured to contact the movable part (20) at a predetermined position to prevent the movable part (20) from moving; wherein the stopper (10) is mainly formed of an elastomer and comprises a stop surface (11), the elastomer being configured to be deformed when the movable part (20) collides with the stop surface (11) in a first direction; and wherein the elastomer further comprises holes (12). With the holes being provided in the elastomer, impact resistance of the elastomer is enhanced, and performance deterioration of the elastomer due to a temperature rise is compensated.
Abstract:
A power relay (1) for a vehicle is disclosed, in particular for a utility vehicle. The power relay (1) comprises a housing (2) formed by a connector base (3) and a housing can (4) set thereon, two connection bolts (10) being inserted into the connector base (3) for contacting a load circuit. The power relay (1) further comprises a coil subassembly (20) arranged in the housing and comprising a solenoid coil (30) and an armature (24). The armature (24) is coupled by a force-transmission member (23) to a contact bridge (22) and can shift in the housing, under the effect of a magnetic field generated by the solenoid coil (30), in such a way that the contact bridge (22) can be reversibly moved between a closing position, in which the contact bridge (22) bridges the connection bolts (10) in an electroconducting manner, and an opening position, in which the contact bridge (22) is not in contact with the connection bolts (10). The housing can (4) is designed as an injection-moulded component made of plastics.
Abstract:
A relay comprising two parallel thermally coupled current paths is particularly fail-safe. If one main contact fails, the additional load current is conducted over the remaining operational main contact. The failed main contact and the thermal connection between the two main contacts then function as heat sinks, thus allowing the relay to continue operating.
Abstract:
An electromagnetic relay which comprises a bobbin comprising a winding part jaw parts extending from both ends of the winding part, and a pair of opposing side wall parts; a coil wound on the winding part of the bobbin; an iron core attached to the bobbin; an armature supported so as to be freely swung by a hinge spring and magnetically attracted to one end of the iron core by supplying a current to the coil; a movable contact which contacts or is separated from a fixed contact in accordance with a swing movement of the armature; and a case that accommodates the elements, wherein the jaw part of the bobbin is formed to extend partly toward a side wall of the case from the winding part so as to separate a space where the coil exists from a space where the fixed contact and the movable contact exist, and wherein each of the side wall parts extends from the jaw part along an axis of the bobbin in a direction toward the space where the fixed contact and the movable contact exist.
Abstract:
A contactor mounting system (100) is disclosed herein. A contactor (105) is directly mounted to the printed wire board (120). Pins (150) may be coupled to an exposed end portion of a first stationary lead (110) and a second stationary lead (115) of the contactor (105). Pins (150) may be configured to interconnect the contactor (105) to the printed wire board (120).
Abstract:
Current correction control is carried out by control process of a control circuit 13 that temperatures of the electromagnetic relays 18a and 18b are assessed one by one based on the detection temperature by the temperature sensor 18c, when the temperature assessed value rises over the predetermined value, the upper limit of the target current value of the motor 11 is decreased.
