摘要:
A contact mechanism (2) of an electromagnetic relay comprises a contact assembly (21), a movable contact assembly (22) and a driving unit (23). The contact assembly (21) comprises a bottom plate (211), an upper case (212) disposed on the bottom plate (211), and two stationary contact heads (213) disposed on and penetrating the upper case (212). The movable contact assembly (22) comprises a central axis (222) passing through the contact assembly (21), a movable contact plate (221) disposed on the top portion (222a) of the central axis (222) and configured to contact with or separate from the two stationary contact heads (213), and a cover element (223) covering the central portion (222b) of the central axis (222). The driving unit (23) is disposed around the lower portion (222c) of the central axis (222) and configured to drive the central axis (222) to move back and forth along the axial direction for allowing the movable contact plate (221) to contact with or separate from the two stationary contact heads (213).
摘要:
An auxiliary relay of an electronic contactor has its conducted state controlled by a plurality of lead switches, in a non-exposed state of contact parts to the outside. This may prevent dust or foreign materials from clinging to the contact part.

An interconnect assembly for a switching assembly in which the switching assembly includes a bus bar and an electromagnetic switching device having a contactor bus. The interconnect assembly is structured to mechanically couple and electrically connect the contactor bus to the bus bar. The interconnect assembly includes a socket member structured to engage the bus bar, a post assembly that includes a post member structured to extend through the contactor bus, in which at least a portion of the post member extends into the socket member, and a locking member disposed on the post member. The locking member is structured to extend through and removably engage the socket member in order to mechanically couple and electrically connect the contactor bus to the bus bar.

A power distribution system includes an electrical contactor arrangement. The electrical contactor arrangement includes a first contactor post, a first contactor lead, and a second contactor lead. The first contactor post extends from a first bus bar. The first contactor lead extends from the first contactor post. The first contactor lead is at least partially received within a contactor housing. The second contactor lead is spaced apart from the first contactor lead and extends from the first contactor post. The second contactor lead is at least partially received within the contactor housing.

A relay assembly comprises a relay mounted on a board. The relay may be a single or individual relay or a polyphasic relay. The relay has a housing (3) and at least one dip solder pin extending from the housing and soldered to a circuit board. The relay is mounted on the circuit board via at least one fastening clip (5) having a fitting part (6, 9) fitted into a hole in the housing, a latching part (9) latched to a bore in the board, and a central flange (7) between the fitting part (6, 9) and the latching part (9).

摘要:
The invention relates to a small bistable high-performance relay, comprising an insulating-material housing with a first housing chamber (1b) in which a single-phase contact module (4) with two busbars (8a, 8b) and a contact spring (13) are arranged, wherein the contact spring (13) is fixedly connected with one leg end to one of the busbars (8a) and acts with its other free leg end that carries at least one mobile contact (20) upon at least one fixed contact (21) located on the second busbar (8b), and wherein a bistable magnetic actuator module (3) having a pivotable armature (11) is arranged in a second housing chamber (1a), said armature deflecting the contact spring (13) by means of an output device (6; 23) arranged in the housing in order to close or interrupt a circuit via the busbars (8a, 8b). According to the invention, the contact module (4) and the actuator module (3) are arranged in one or two levels in the insulating-material housing, wherein the contact module (4) comprises a multi-layered contact spring (13) that is bent in a U shape to form an electrodynamic current loop while the actuator module (3) comprises a one-piece, U-shaped yoke (14) having at least one excitation coil (17) per yoke limb and a yoke center limb (16) supported by a flat permanent magnet (15) and on which is mounted a slightly V-shaped rocker armature (11).
