Abstract
Disclosed is a monopole direct current switch, comprising a base component, an electromagnetic system, a contact system and a transmission component. The contact system includes a movable contact and a static contact fixed on the base. The electromagnetic system includes an installation plate, an annular magnetizer, a cylindrical magnetizer, a magnetic yoke and an electromagnetic coil. The base component is connected with the electromagnetic system through the installation plate. The transmission component is arranged in the center of the base component and the electromagnetic system. The transmission component includes a transmission shaft and a spring nested on the transmission shaft. The spring is arranged between the magnetic yoke and the transmission shaft. A keeper is arranged on the lower end of the transmission shaft on which a movable contact is arranged. A buffering spring and a spring seat are arranged on the upper part of the movable contact. Insulated pads are respectively arranged between the movable contact and the spring seat and between the movable contact and the transmission shaft. The insulation of the main circuit towards the ground is improved by the utility model. When closing the movable and the static contacts, the bouncing in the instant and the fusion welding phenomenon are avoided because of the buffering spring so that the contact reliability is increased and the heating of the contact is reduced. The service life of product is improved.
Description
Technical field:
The utility model relates to electric switch element, especially a kind of one pole dc switch element.
Background technology:
Dc switch element in the prior art is made up of electromagnetic system, drive system and one group of contact, and the closed action between its contact normally relies on electromagnetic system to drive that power transmission shaft realizes.
Summary of the invention:
Technical problem to be solved in the utility model is: because dc switch element of the prior art is made up of electromagnetic system, drive system and contact usually, closed action between its contact relies on electromagnetic system to drive power transmission shaft usually and realizes, owing to do not possess buffer unit in the drive system, tend to bounce in the moment of closure between contact, thereby the melting welding phenomenon takes place when causing contact closure, contact reliability is lower, and the useful life of product is not high.The utility model is to solve the problems of the technologies described above the technical scheme that is proposed to provide a kind of one pole dc switch, described this one pole dc switch comprises base assembly, electromagnetic system, contact system, transmission component and spring, wherein, described contact system includes a moving contact and a fixed contact, described base assembly has comprised a pedestal, in described pedestal, be embedded with nut, fixed contact in the described contact system is fixed on the pedestal by sunk screw, described electromagnetic system includes mounting panel, annular magnetizer, the cylindrical magnetic conducting body, yoke and solenoid, described base assembly is fixedlyed connected with electromagnetic system by the mounting panel in the electromagnetic system, described transmission component is arranged on the central authorities of base assembly and electromagnetic system, described transmission component is by a power transmission shaft, be linked in buffer spring and spring base on the described power transmission shaft, insulating case and insulation cushion constitute, the centre bore that described power transmission shaft passes described pedestal enters the center of electromagnetic system, the lower end of described power transmission shaft is connected with a columniform armature, moving contact in the described contact system is installed on the described power transmission shaft, the top of moving contact is provided with described buffer spring and spring base, be provided with described insulating case and insulation cushion between moving contact and the spring base and between moving contact and the power transmission shaft, also be provided with a spring between described yoke and power transmission shaft, an alignment pin that radially passes power transmission shaft is limited in described spring between yoke and the power transmission shaft.After the solenoid energising, excitation produces suction, the pressure that armature overcomes described spring drives power transmission shaft and upwards action of moving contact, make dynamic and static contact separately, otherwise, when solenoid cuts off the power supply, the refusal of excitation, armature drives power transmission shaft and moving contact and moves downwards under the effect of spring, makes dynamic and static contact closure.The utility model and prior art contrast, because a contact is fixed on the pedestal as fixed contact, improved major loop insulating properties over the ground, again because on power transmission shaft, be provided with buffer spring, so it is moving, fixed contact did not bounce in the moment of closure, contingent melting welding phenomenon when having avoided contact closure, also increased simultaneously contact reliability, reduced the heating of contact, product has been improved useful life, in addition, because during the solenoid outage, moving, fixed contact just can closed be worked, so when moving, during the work of fixed contact closure, solenoid can not generate heat because of energising.
