摘要： PROBLEM TO BE SOLVED: To provide a sealed contact device capable of preventing damage to a junction part of a sealing vessel and a fixed contact.
SOLUTION: A junction part 17a formed at one end part of a bus bar 17 made of a conductive material and formed in a slender plate shape is screwed to a fixed terminal 2 exposed outside of a housing C with its rear face in contact with the fixed terminal 2. A terminal part 17b to which an electric wire is to be connected is fitted to the other end part of the bus bar 17. A load receiving part 19 in contact with one end of the bus bar 17 at the junction part 17a side, both sides of the junction part 17a in a direction crossing a length direction of the bus bar 17 along the surface of the junction part 17a, and the surface of the junction part 17a are provided at the housing C. Even if the bus bar 17 receives force of pushing toward the junction part 17a side of the bus bar in the length direction or force in a direction tearing it off from the fixed terminal 2, the force is released to the load receiving part 19, so that force added on a junction part of a fixed contact retaining member 11 and the fixed terminal 2 constituting the sealing vessel is alleviated to prevent damage.

摘要： PURPOSE:To stably maintain the specific value of a suction current and a hold ing current. CONSTITUTION:The conduction of a coil L of an electromagnet device is controlled by a switching element 1. A coil current is detected by a current detector 6 so as to amplify the detected output by an amplifier 12. The amplification factors of this amplifier 12 in the suction and holding times are converted into the outputs from a controller 4. The output from the amplifier 12 is amplified by the difference between the integrating output from an integrator 7 and the reference voltage using an error amplifier 8. The coil current is controlled at a specific value by controlling the on-term of the switching element 1 corresponding to the output from the error amplifier 8 using a PWM controller 9. The detection level of the coil current is converted by substituting the conversion of the amplification factors of the amplifier 12 in suction and holding times for the conversion of the reference voltage of the error amplifier 8. Through these procedures, the suction current and the holding current can be stably maintained at a specific value without being affected by the dispersion in DC voltage of the other circuits.

摘要： PURPOSE:To provide an electromagnet drive device capable of keeping the attracting state even when an external force acts thereon under the attracting state. CONSTITUTION:An electromagnet device has an armature, and an attracting force acts between an iron core and the armature when a current is carried to a coil Co. A pulse width control part 13 controls a switching element S in such a manner that a relatively large starting current for starting is carried to the coil Co for a certain time when a trigger pulse is inputted, and a holding current required to hold the attracting state between the iron core and the armature is carried to the coil Co after the elapse of the certain time. A current detecting part 15 detects the current of the coil Co and generates a re-trigger pulse through a re-trigger pulse generating part 16 when the electromagnet device is transferred from the attracting state to the non-attracting state. A trigger pulse generating part 12 starts the pulse width control part 13 in the same manner as the starting time, when the re-trigger pulse is inputted, to carry a large starting current to the coil Co.

摘要： PURPOSE:To obtain the zero cross switching relay with less heat evolution from which noise hardly takes place with simple configuration. CONSTITUTION:A contact 20 of an electromagnetic relay and a 2-way thyristor 21 of light trigger type are connected in parallel, and after the contact 20 is opened, the thyristor 21 is subject to zero cross turn-off. When the thyristor is turned on and a voltage between output terminals 3,4 is dropped, an optical signal of light emitting diodes 18,19 is lost, a photo transistor(TR) 14 is turned off and power is supplied to a coil 15 of an electromagnetic relay and a light emitting diode 16 to allow the thyristor 21 to be in zero cross turn-on. As a result, since a main current is obtained via a contact of the electromagnetic relay, heat evolution is less and since turning-on and turning-off are implemented in the vicinity of a zero cross point, noise production is less and the relay is manufactured inexpensively with simple configuration.

摘要： PURPOSE:To provide the semiconductor relay not causing a surge generating source when a 2-way thyristor with a large power capacity energized by an AC power supply is connected between relay output terminals. CONSTITUTION:A 2-way thyristor 6 is connected between relay output terminals 3, 4 and two photo thyristors 7, 8 having a zero cross function are connected in anti-parallel between a gate terminal of the 2-way thyristor 6 and one main electrode terminal to couple optically the two photo thyristors 7, 8 with a light emitting diode 5 connected between relay input terminals 1, 2. When the semiconductor relay with a large power capacity energized by an AC power supply is employed, the relay is controlled with a comparatively small input signal and the occurrence of a surge generating source is prevented.

摘要： PROBLEM TO BE SOLVED: To secure the safety of surrounding work without a lock means flipping out suddenly by providing a lock means so that the quantity of its shifting may be regulated when it takes off the occupation of space for movement of a mobile part or a interlock part. SOLUTION: Rotating a knob 17 for operation with a shaft 15 as its axis of rotation will release the lock between the lock pin 16b and the groove of the body 13, but at this time, a lock means EE shifts outward of a housing DD with the energizing force of a return spring 18, that is, in the direction of taking off the occupation of space for movement. The lock pin 16 abuts on the groove of the case 12, and the quantity of the shifting in its direction is regulated. Hereby, a person working in circumference never gets in dangerous condition, and he can do without work of removing the occupation of space for movement, and can break a fixed contact slightly fused together surely from the mobile contact.

摘要： PURPOSE: To sufficiently elongate an arc to increase an interrupting voltage, and improve contact opening and closing performance by providing a clearance between a fixed contact and a return spring housing part. CONSTITUTION: When an arc AA is generated between movable and fixed contacts 9a, 8b, the arc AA is traveled along one surface 9b of the contact 9, then smoothly traveled along a movable contact holder which becomes flush with the one surface 9b, and finally linked between a pair of contacts 8b. The Lorentz force received from a magnetic means by the arc AA in this state is in the direction making contact with the contact, the arc AA is traveled in the deep part of a clearance 16c, and also traveled along the inner edge part of the groove part 16d of a housing part 16, so that the arc AA is sufficiently elongated. Thus, the interrupting voltage is increased, never interfering with the contact opening and closing performance.

摘要： PURPOSE:To eliminate an arc at a contact section by connecting an FET in parallel with the section, and providing a delay circuit for generating a delay signal for turning OFF the FET by delaying from the section. CONSTITUTION:When a switch S0 is closed, an electromagnet driver A and a delay circuit 2 are simultaneously turned ON. When a plunger M3 is separated from a core M2, an electromagnet M is driven by large power to complete attracting, then driven by low power, and a contact section C is turned ON. On the other hand, the circuit 2 drives a gate of an FET 1 through an oscillator 3, an insulating transformer 4 and a rectifier 5 to turn ON the FET 1. When the switch S0 is opened, a regenerated current flows to a regenerating circuit of the driver A to so control that the plunger M3 is delayed at its resetting speed to be reset, and the section C is turned OFF. On the other hand, the circuit 2 generates a delay signal, and an oscillation signal from the oscillator 3 drives the gate of the FET 1 through the transformer 4 and the rectifier 5, and the FET 1 is turned OFF by delaying as compared with the section C.
