Abstract
The utility model relates to a remote intelligent switch. The switch comprises a shell, wherein an electromagnetic coil is mounted in the shell; an electromagnetic iron core is arranged in the electromagnetic coil; two ends of the electromagnetic iron core are respectively connected with two L-shaped steel magnets; two magnetic steel pieces mutually parallel are fixed on two sides of a support body; a support shaft is arranged in the center of the support body between the two magnetic steel pieces and connected to the shell; the axis of the support shaft is parallel to the end surfaces of the two L-shaped steel magnets; the two magnetic steel pieces swing freely around the support shaft and along with the support body to be contacted with the L-shaped steel magnets alternately; at least one swinging arm is connected with the magnetic steel pieces and connected with a contact arm of a main contact of the switch; a microswitch is mounted in the shell; the swinging arm swings to be in contact with the microswitch; and the microswitch is provided with at least one group of contacts. The remote intelligent switch has a compact structure, can be switched on and off by adopting the current pulse method, and can be kept in the on/off state; and the L-shaped steel magnets push the magnetic steel pieces to act, so that the contacts have high contact reliability and low failure rate.
Description
Technical field
The utility model belongs to electric-controlled switch, relates in particular to a kind of long-distance intelligent switch.
Background technology
At present along with the progress of science and technology is realizing intelligent management for the control of electrical network, particularly need develop more electric equipment for the intelligent management of residential customer, cooperation needs a kind of distribution compact electromagnetic switch to user's sampling, the method realization switch motion and the maintained switch state that touch with point are constant, feedback signal in action, be no longer to need the solenoid energising to keep after the switch motion, in order to realize this function, can realize from circuit with relay commonly used now, but use a plurality of devices to overlap with outer circuit, the time-consuming cost height of complex circuit, but also it is big to take up room, and is unfavorable for the on-the-spot requirement of using of present far-end sequencing control.
Summary of the invention
The purpose of this utility model is the technical scheme that has proposed a kind of long-distance intelligent switch for addressing the above problem, this scheme adopts permanent magnet as movement arm, magnet and coil are as the promotion source, change the energising direction of coil and then the polarity of change magnet, realize the Push And Release of contact thereby promote the permanent magnet action.
For achieving the above object, the technical solution of the utility model is: a kind of long-distance intelligent switch, include a housing, solenoid is installed in housing, electromagnetic core is arranged in the solenoid, be connected with a L shaped magnet steel respectively at the two ends of electromagnetic core, an end face of two L shaped magnet steel is parallel relatively, there are two magnetic links to be parallel to each other and are fixed on supporter both sides, supporter center between two magnetic links is provided with back shaft, back shaft is connected on the housing, the axis of back shaft is parallel with the end face of described two L shaped magnet steel, and back shaft is in two parallel relative centers of L shaped magnet steel end face, and two magnetic links are that the center freely swings and alternately touches L shaped magnet steel with the back shaft with supporter; Have at least a swing arm to be connected with magnetic links, swing arm connects switch main contacts contact arm, and sensitive switch is installed in housing, and the swing of swing arm touches sensitive switch, and the contact of sensitive switch has one group at least.
Described electromagnetic core and L shaped magnet steel be connected to riveted joint.
Described switch main contacts is two groups.
The contact of described sensitive switch has two groups.
The utility model has the advantages that: compact conformation, the method with current impulse of having accomplished in a switch realize switch motion and keep, and in action feedback signal, the function that promptly no longer needs the solenoid energising to keep after the switch motion; L shaped magnet steel of the present utility model promotes the moving structure of doing of magnetic links, the reliability height of contact point contact, and failure rate is low.
Below in conjunction with drawings and Examples the utility model being done one describes in detail.

Fig. 3 the utility model contact schematic diagram.
Embodiment
A kind of long-distance intelligent switch embodiment, described switch includes a housing 1, solenoid 2 is installed in housing, electromagnetic core is arranged in the solenoid, be connected with a L shaped magnet steel (permanent magnet) 3 respectively at the two ends of electromagnetic core, an end face 3-1 of two L shaped magnet steel is parallel relatively, there are two magnetic links (permanent magnet) 4 to be parallel to each other and are fixed on supporter 5 both sides, supporter center between two magnetic links is provided with back shaft 6, back shaft is connected on the housing, the axis of back shaft is parallel with the end face of described two L shaped magnet steel, and back shaft is in two parallel relative centers of L shaped magnet steel end face, and two magnetic links are that the center freely swings and alternately touches L shaped magnet steel with the back shaft with supporter; Have at least a swing arm 7 to be connected with magnetic links, swing arm connects switch main contacts contact arm 8, sensitive switch 9 is installed in housing, the swing of swing arm touches sensitive switch, the contact 9-1 of sensitive switch has one group at least, also be provided with signal and draw socket 10 in housing, the contact line of the power line of solenoid, sensitive switch is connected to socket and draws, and the solenoid among the embodiment is a d-c solenoid.
Operation principle of the present utility model is: d-c solenoid is by changing the electric power polarity of input, the polarity of the L shaped magnet steel at magnetic core two ends changes thereupon, because the polarity of two magnetic links is constant therefore along with the variation of L shaped magnet steel polarity, two magnetic links are inhaled moving up and down, drive swinging arm and then drive the action that main contacts has switch, also driven the sensitive switch action that auxiliary contact are arranged simultaneously.
In order to guarantee that L shaped magnet steel well is connected with electromagnetic core, described electromagnetic core and L shaped magnet steel be connected to riveted joint.
Main contacts can be provided with many groups as required, and the described switch main contacts of present embodiment is two groups.
The contact of sensitive switch also can dispose one or more groups as required, and the contact of the described sensitive switch of present embodiment has two groups.
