Abstract
The invention provides an electromagnetic relay which comprises a base, a control circuit and an output circuit. A vertical column vertical to a base plane is arranged at the center of the base. The top end of the vertical column is movably connected with the middle part of an armature. A movable contact is arranged on one end of the armature. An electromagnet is arranged at the position corresponding to the base plane below one side of the armature. The electromagnet and the control circuit are connected. The other side of the armature is connected with the base through a reset spring. A permanent magnet is arranged on the top end of an iron core in the electromagnet. A fixed contact which is used with the movable contact is arranged below the movable contact. The fixed contact and the output circuit are connected. The electromagnetic relay provided by the invention has the advantages that the electromagnetic relay has the advantages of simple structure and convenient use; current strength required by maintaining the work of the electromagnetic relay is effectively reduced; and energy loss is reduced.
Description
(1) technical field
The present invention relates to a kind of circuit control appliance, particularly relate to a kind of electromagnetic relay.
(2) background technology
At present, aspect circuit control, electromagnetic relay is brought into use in increasing field.Yet now electromagnetic relay is on the market after starting working output circuit is communicated with, needing to continue a large amount of electric currents of output makes the electromagnet in electromagnetic relay produce magnetic force, the effect that resetting means in opposing electromagnetic relay produces, keep armature contact in electromagnetic relay to contact with fixed contact, thereby maintain the connected state of output circuit, if be large-scale electromagnetic relay, the electric energy expending is huger.Therefore, be necessary existing circuit control appliance to improve, make electromagnetic relay in work, effectively reduce the magnitude of current that maintains relay work, reduce the consumption of the energy.
(3) summary of the invention
In order to overcome the weak point of available circuit control appliance, the invention provides a kind of electromagnetic relay.
Technical scheme of the present invention is to realize like this.
A kind of electromagnetic relay of this programme, comprises base, control circuit and output circuit, and described base centre is provided with the column vertical with base plane, and this column top is flexibly connected with armature middle part; Described armature one end is provided with armature contact, on the corresponding base plane of this side armature below, is provided with electromagnet, and this electromagnet is communicated with control circuit, between described armature opposite side and base, by back-moving spring, is connected; The iron core top of described electromagnet inside is provided with permanent magnet; Described armature contact below is provided with fixed contact matching used with it, and this fixed contact is communicated with output circuit.
Described armature middle part is connected with the rotating shaft of column top.
Usefulness of the present invention is: this electromagnetic relay is simple in structure, easy to use, can effectively reduce needed current strength while maintaining electromagnetic relay work, thereby reduces the loss of the energy.
(4) accompanying drawing explanation
Accompanying drawing is institutional framework schematic diagram of the present invention.
(5) embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made to brief description.
As a kind of electromagnetic relay of figure, comprise base 1, control circuit 10 and output circuit 9, described base 1 centre is provided with the column vertical with base plane 2, and these column 2 tops are flexibly connected with armature 3 middle parts; Described armature 3 one end are provided with armature contact 4, in corresponding base 1 plane of this side armature below, are provided with electromagnet 5, and this electromagnet 5 is communicated with control circuit 10, between described armature 3 opposite sides and base 1, by back-moving spring 7, are connected; The iron core top of described electromagnet 5 inside is provided with permanent magnet 6; Described armature contact 4 belows are provided with fixed contact 8 matching used with it, and this fixed contact 8 is communicated with output circuit 9.
Described armature 3 middle parts are connected with column 2 top rotating shafts.
The course of work of this example: when using this equipment to carry out circuit control, connect control circuit 10, electromagnet 5 is started working, under half section of armature of correspondence 3 is inhaled, because the iron core top in electromagnet 5 is provided with permanent magnet 6, can act on electromagnet 5 simultaneously, resist together the active force that back-moving spring 7 produces, make armature contact 4 and fixed contact 8 continuous contacts, thereby keep output circuit 9 in connected state.In this process, due to the existence of permanent magnet 6, required the providing for resisting the magnetic force of back-moving spring 7 of electromagnet 5 reduced greatly, thereby the required current strength providing of control circuit 10 has been provided, reduced the loss of the energy.When needs are stopped using this equipment, closing control circuit 10, one section of armature 3 at back-moving spring 7 places can be left behind, one section of armature at armature contact 4 places is pulled up, and now, armature contact 4 separates with fixed contact 8, output circuit 9, in off-state, quits work.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
