Abstract
A contact type self-protective DC phase-reversing combined switch is composed of two four-contact four-pole single-throw switches, which are connected via their normally closed contacts and normally open contact. By pressing the button of one of the switches, a different output phase state is formed. The circuit has the advantages of simple structure, good expansion control performance, large circuit load selection area, self protection and low manufacturing cost.
Description
But the utility model relates to a kind of contact self-insurance direct current paraphase unit switch, but particularly a kind of self-insurance direct current paraphase unit switch that utilizes common contact switch Combination Design to form.
At present, the device of direct current paraphase generally adopts complex circuit design, and perhaps custom-designed mechanical switch carries out, and has complex structure, accommodation limitation, and cost of manufacture is higher, and the self-protection when being not easy to misoperation.
According to above situation, but the utility model provides a kind of contact self-insurance direct current paraphase unit switch at this, can only pass through common contact switch, by certain logical combination, under the prerequisite that the input phase place is determined,, change the phase state of output arbitrarily through simple operations, and when misoperation, cut off the electricity supply automatically, thereby but realize the paraphase of self-insurance direct current.
Concrete structure of the present utility model is as follows.
But contact self-insurance direct current paraphase unit switch described in the utility model is combined by two four contact four blade single-throw switches, and described switch can be non-self-lock switch, i.e. monostable switch, but also can be self-lock switch, i.e. bistable switch.Wherein one of every switch group of engage contacts state can Synchronization Control.For the convenience of narrating, existing four contacts with first switch are named as I-B1, I-K1, I-B2 and I-K2 respectively, and on behalf of this contact, letter b wherein be in normally off, and on behalf of this contact, alphabetical K be in normally open; Equally, four contacts of second switch are named as II-B1, II-K1, II-B2 and II-K2 respectively, and the meaning that letter b wherein, K express is identical with above-mentioned first switch.The utility model circuit structure is as follows.
Described I-B1 connects with II-K1, and I-K2 connects with II-B1, and I-B2 connects with II-K2, and I-K1 connects with II-B2.Simultaneously, I-B1 is in parallel with I-K1 simultaneously as a utmost point D of DC power supply, and I-B2 while in parallel with I-K2 is as another utmost point 0 of DC power supply; II-K1 is in parallel with II-B1 simultaneously as a utmost point B of direct current output, and II-K2 while in parallel with II-B2 is as another utmost point A of direct current output.Please note that two switches all are to be connected mutually with the normally opened contact of another switch by the normally-closed contact of a switch here.When two switches all in a state of nature, when promptly not pressing any button, DC power supply since combinations thereof be not communicated with any one output; Press the wherein button of a switch, four contacts status of this switch overturn simultaneously, cause with the contact of the corresponding series connection of another switch and form homomorphism, and making wherein, an output stage and another output stage form a kind of phase state; Press the wherein button of another switch, four contacts status of this switch overturn simultaneously, cause with the contact of the corresponding series connection of first switch and form homomorphism, make wherein that an output stage and another output stage form another kind of phase state, thereby only reach the purpose of selecting output phase by the state of selecting to change a switch.If misoperation, the state of two switches that overturn simultaneously, apparent, the combination of contact still can not reach connected state, power supply still not can with the output conducting, thereby reach the self-insurance purpose.
In view of the above, it is simple that the utility model has reached circuit structure, and the expansion control performance is good, and circuit load selects face big, but self-insurance, the purpose that cost of manufacture is cheap.
Describe a kind of embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the structural principle schematic diagram of the utility model embodiment.
According to Fig. 1, but contact self-insurance direct current paraphase unit switch described in the utility model, by two the four non-locking press button switches 1 of contact four single-pole single-throws and 2, be named as I respectively and II combines, wherein the engage contacts state of every switch can be by button 11 separately, be named as I-AN and 21, be named as II-AN Synchronization Control.Four contacts of switch I are named as I-B1, I-K1, I-B2 and I-K2 respectively, and on behalf of this contact, letter b wherein be in normally off, and on behalf of this contact, alphabetical K be in normally open; Equally, four contacts of switch II are named as II-B1, II-K1, II-B2 and II-K2 respectively, and the meaning that letter b wherein, K express is identical with above-mentioned first switch.
Described I-B1 connects with II-K1, and I-K2 connects with II-B1, and I-B2 connects with II-K2, and I-K1 connects with II-B2.Simultaneously, I-B1 is in parallel with I-K1 simultaneously as a utmost point D of DC power supply, and I-B2 while in parallel with I-K2 is as another utmost point 0 of DC power supply; II-K1 is in parallel with II-B1 simultaneously as a utmost point B of direct current output, and II-K2 while in parallel with II-B2 is as another utmost point A of direct current output.Please note that two switches all are to be connected mutually with the normally opened contact of another switch by the normally-closed contact of a switch here.When two switches all in a state of nature, when promptly not pressing any button, DC power supply since combinations thereof be not communicated with any one output; Press the button 11 of switch 1, four contacts status of this switch overturn simultaneously, cause with the contact of the corresponding series connection of switch 2 and form homomorphism, this moment, I-K2 was communicated with II-B1, I-K1 is communicated with II-B2, one end D of power supply is communicated with output terminals A with II-B2 by I-K1, and the other end 0 of power supply is communicated with the formation loop by I-K2 and II-B1 with output B; Equally, press the button 21 of switch 2, four contacts status of this switch overturn simultaneously, cause with the contact of the corresponding series connection of switch 1 and form homomorphism, one end D of power supply is communicated with output stage B, the other end 0 of power supply is communicated with output terminals A, forms another kind of phase state, thereby reaches the purpose of only selecting output phase by the state of selecting a switch of change.If misoperation, the state of two switches that overturn simultaneously, apparent, the combination of contact still can not reach connected state, power supply still not can with the output conducting, thereby reach the self-insurance purpose.
