摘要： There is provided an electromagnetic contactor with which it is possible to suppress electromagnetic repulsion forces which cause a movable contact to open when current is conducted without any effect of magnetic fields of external connection conductors. The electromagnetic contactor includes a contact mechanism (CM) including a pair of fixed contacts (2), interposed in a current conduction path, which have their respective fixed contact portions (2a), (2b) and a movable contact 3 having a pair of movable contact portions (3b), (3c) which are able to come into and out of contact with the pair of fixed contact portions, wherein at least one of the pair of fixed contacts or movable contact is formed in a shape such as to form magnetic fields which generate Lorentz forces opposing electromagnetic repulsion forces generated in an opening direction between the fixed contact portions and movable contact portions when current is conducted. Also, the attachment direction of fixed portions (22), (23), each of which, having an external connection conductor (20), (21) connected to an external connection terminal (2i), (2j) of the corresponding fixed contact 2, is attached to the external connection terminal of the external connection conductor, is set so as to cross the direction of current flowing through the movable contact.

摘要： A relay (70) includes contacts (73) residing within a glass tube (72). A coil (76) surrounding the tube (72) and a switch (66) are connected in parallel between two terminals (77) of the relay (70). A current source supplies a current to the coil (76) and switch (66). When the switch (66) is open, substantially all of the current passes through the coil (76) and the coil (76) produces a sufficient amount of magnetic flux to close the relay's contacts (73). When the switch (66) closes, it shunts a sufficient amount of the current away from the coil (76) to reduce the magnetic flux it produces below the level needed to keep the contacts (73) closed. The current source is sized so that the coil (76) requires relatively few turns, thereby allowing the relay (70) to be relatively thin. The coil (76) is formed by a conductor (140) embedded in an insulating substrate (128) surrounding the tube (72).

摘要： A coaxial relay is build up from a contact block 10 and an electromagnet block 60 . The contact block 10 carries a plurality of coaxial connectors 20 each composed of a core conductor 21 and a shield conductor 22 surrounding the core conductor 21 . The core conductors 21 extend into a shield chamber 12 to define thereat respective coaxial contacts. At least one movable blade 41, 42 is disposed within the shield chamber 12 for closing and opening the two adjacent coaxial contacts. The movable blade 41, 42 is provided with a dielectric actuator 44 which projects on the top of the contact block 10 and is engaged with a return spring 50 secured to the contact block 10 for urging the movable-blade 41, 42 in a direction of opening the coaxial contacts. The electromagnet block 60 carries at least one electromagnet 86 and an armature 100 which is engageable with the actuator 44 when the electromagnet block 60 is assembled to the contact block 10 . The armature 100 moves about a pivot axis X from a first position of opening the coaxial contacts to a second position of closing the same. The electromagnet 86 includes a frame 70 of a non-magnetic material which holds the electromagnet 86 and has its lower end secured to the contact block 10 . The frame 70 has a retainer mechanism for pivotally supporting the armature 100 . Thus, a magnetic gap distance between the electromagnet 86 and the armature 100 can be fixed and does not vary a the time of assembling the electromagnet block 60 to the contact block 10 , so that the relay can have a reliable armature movement in response to the excitation of the electromagnet 86 .

摘要： A high frequency relay comprises a contact base block (1) having pairs of fixed contacts (70), contact members (21) with movable contacts (22), and an electromagnet (3) for moving the contact members (21) to open and close the fixed contacts (70) by the movable contacts (22). The contact base block (1) comprises an injection-molded base having projections on its front surface, first metal films formed as the fixed contacts on top surfaces of the projections, second metal films formed as connection terminals for outside devices on a rear surface of the base, each of which corresponds to one of the first metal films, through holes (16) each having a conductive material on its inner surface to make an electrical connection between one of the first metal films and the corresponding second metal film in the shortest distance, and a third metal film formed on the base to provide electrical isolation from the first and second metal films, which works as electromagnetic shield means as well as ground means.

摘要： Each of first and second contact blocks (1, 1) includes a substantially rectangular insulating member, a pair of stationary contact members projecting inward from the insulating member and supported with a predetermined interval therebetween, a movable contact member arranged between the pair of stationary contact members and supported by the insulating member, and first, second, and third terminals for electrically extracting the pair of stationary contact members and the movable contact member, respectively, and projecting from a base portion of the insulating member with predetermined intervals therebetween. An electromagnet (30) includes a movable member for commonly acting on the movable contact members of the first and second contact blocks (1, 1) to move each movable contact member toward one of the pair of stationary contact members of each of the first and second contact blocks (1, 1). A shielding block member (17) with a substantially H-shaped section includes two storage spaces for storing the first and second contact blocks (1, 1), respectively, a support portion for mounting the electromagnet (30), and a predetermined number of notched portions for guiding the first, second, and third terminals of each of the first and second contact blocks. At least a surface of the shielding block member has conductivity. A shielding case (31) shields at least an edge of an opening portion of the shielding block member (17).

摘要： An electromagnetic relay includes a coil wound around a core both of whose ends project therefrom. A yoke extends parallel thereto, and each of its ends is formed with two pole pieces which extend towards and lie one on each side of an end of the core with a certain gap being defined therebetween. A connecting member extends parallel to the core and the yoke and is mounted so as to be movable transversely, and means are provided for establishing and breaking some electrical connection according to such transverse movement. There are provided two armature pieces, one for each end of the core and both fixed to the connecting member. Each armature piece includes a permanent magnet plate and two plates of magnetic material fixed to it so as generally to form a C shape with one of the magnetic material plates being magnetized to be a north pole and the other a south pole. Each of the two plates of magnetic material is inserted on one side of an end of the core between it and the opposing one of the pole pieces of the yoke, into the gap therebetween. The directions of magnetization of the armature pieces are oppositely oriented. Thereby, when the relay switches over, it does so without generating any off center jerking, and thus its mounting to a base is improved. Also the quality of the magnetic circuit, and the manufacturablity of the relay, are improved.
