摘要： PROBLEM TO BE SOLVED: To minimize coil loss and a stray magnetic flux. SOLUTION: At least two iron cores 15, 16 to extend out in parallel with each other along the overall length of one common coil 18 are provided on a magnetic system for an electromagnetic relay. Each of the iron cores is a part of a characteristic magnetic circuit to actuate an armature, and the armature actuates a contact system to correspond by being arranged in this magnetic circuit. An interval between the iron cores 15, 16 inside of the coil 18 is made smaller than the maximum dimensions of a cross-sectional surface of each of the iron cores, and the loss and the stray magnetic flux are minimized by using the magnetic flux to generate on the coil 18 to the maximum.

摘要： PROBLEM TO BE SOLVED: To provide a spring contact unit for a relay having an oscillating armature, which is easy to design and produce and suitable also for a high-frequency relay. SOLUTION: The spring contact unit comprises spring contacts 9, formed as fringing contacts and a spring portion 7 arranged between the spring contacts 9. The spring contacts 9 are connected to the spring portion 7 in insulated conditions. The spring portion 7 is relatively large, while the spring contacts have small faces. An elastic portion 10 is also provided for giving a contact force so that the spring portion 7 having a larger face can be connected for grounding and the spring contact unit is suitable for high frequency.

摘要： PROBLEM TO BE SOLVED: To provide a compact electromagnetic switch for pressuring a movable contact with high holding force onto a fixed contact along with being compact. SOLUTION: The electromagnetic switch has a cup 3 shaped yoke 1 rotationally symmetrically on the base portion 4 wherein a permanent magnet 5 is disposed. Magnetic flux of the permanent magnet 5 is carried to an armature 11 in a board shape through a core 6 having a core flange 8 in a radial direction. A relation between a magnetic resistance WA in an actuating space formed by the armature 11, the core 6, and the yoke 1 and a magnetic resistance WR in a peripheral space between the core flange 8 and the yoke 1, WA

摘要： PROBLEM TO BE SOLVED: To provide a relay easy to assemble. SOLUTION: This relay is so structured that an electromagnet block 5 composed by incorporating an electromagnet device 3 for executing a connecting- disconnecting operation by attracting a movable frame 1 to an iron core 2 into an electromagnet base 4 is combined with a contact block 8 composed by incorporating a contact device 7 into a contact base 6 different from the electromagnet base 4, and the switching of the contact of the contact device 7 is carried out by the movable frame 1 of the electromagnet device. In this case, a yoke 22 constituting the electromagnet base 4 is provided with projecting parts to be fitted into guide slot parts 35 formed on the electromagnet base 4 at both ends of the yoke 22 with the left and right lengths set different from each other.

摘要： PROBLEM TO BE SOLVED: To make a solenoid small to manufacture at a low price by arranging a magnetizing means at both ends of a bobbin core having a conductive coil wound in the outer circumference, for forming a magnetic field with current, movably fitting an armature within a through hole of the bobbing core, installing a first magnetic body between the both ends of the bobbin core and a magnetizing means, and installing a second magnetic body on the outside of the magnetizing means. SOLUTION: First magnetic bodies 142, 144 magnetized with a permanent magnet 150 have an S pole, and second magnetic bodies 162, 164 have an N pole. When current in the positive direction is supplied to a coil 124, the upper part of an armature 130 has an N pole, attraction is produced to the upper first magnetic body 142, repulsion is produced to the second magnetic body 162, the lower part of he armature 130 has an S pole, repulsion is produced to the lower first magnetic body 144, and attraction is produced to the second magnetic body 164. The armature 130 falls down, presses a pressure fin 240, and lets a contact lead 260 contact with connectors 220, 230.
