Abstract

The invention provides a zener diode adapter, which comprises a first input end, a second input end, a first output end and a second output end; the first input end and the first output end are connected with each other through a conducting wire which is serially connected with more than one zener diode in the same direction; the second input end and the second output end are connected with each other through a conducting wire which is serially connected with more than one zener diode in the same direction; and negative electrodes of the zener diodes collectively face towards the first input end and the second input end or collectively face towards the first and the second output ends. The adapter is arranged between an alternative-current power supply and an electric appliance, so that when staying at an unused status, the electric appliance can be maintained almost open-circuit with an alternative-current power supply system.

Description

The Zener diode adapter

Technical field

The present invention relates to the electric equipment field, especially, is a kind of appliance socket.

Background technology

In family expenses or office electric equipment, some more equipment are owing to need use or need long-time charging everyday, therefore; The user is disinclined to plug plug usually; Thereby make electrical equipment no matter using or non-working condition, be in "on" position for a long time, this is unfavorable for the maintenance of electrical equipment very much; So long-term, with the useful life that influences appliances power source structure and electrical equipment battery.

Summary of the invention

To the problems referred to above, the object of the present invention is to provide a kind of Zener diode adapter, this adapter is connected between AC power and the electrical appliance, can make electrical equipment when non-working condition, and the state that maintenance approaches to open circuit between the ac power supply system.

The technical solution adopted for the present invention to solve the technical problems is: this Zener diode adapter comprises first input end, second input, first output, second output; Said first input end and first output link to each other through a lead that is serially connected with more than Zener diode in the same way; Said second input and second output also link to each other through a lead that is serially connected with more than Zener diode in the same way; And the negative pole of each said Zener diode is jointly towards said first, second input, or jointly towards said first, second output.

As preferably, light-emitting diode of parallel connection on each said Zener diode, said Light-Emitting Diode is prepended to the housing outer surface of said Zener diode adapter.

As preferably; Zener diode quantity between said first input end, first output equates with Zener diode quantity between said second input, second output; So that in the alternating current one-period, positive half period and negative half-cycle have the circuit characteristic of symmetry.

As preferably, the Zener diode quantity between said first input end, first output is 3 ~ 6; Zener diode quantity between said second input, second output is 3 ~ 6.

The invention has the advantages that: this Zener diode adapter in use, after the appliance switch closure, at any one time; Zener diode between said first input end, first output, the Zener diode between perhaps said second input, second output must have one the tunnel to be in the high back voltage state; This high pressure is broken through reverse dead band voltage, makes Zener diode be reversed conducting, at this moment; All Zener diodes all are in low resistive state, can make the electrical equipment operate as normal; When electrical equipment cuts out, only there is little electric current to exist in the electrical equipment, at this moment, electrical equipment is equivalent to a big resistance; Most of voltage of AC power all is divided to the electrical equipment two ends, and the voltage on each Zener diode reduces significantly, thereby get into the voltage dead band, cause Zener diode oppositely to end; So, further reduced said little electric current, made the state that maintenance approaches to open circuit between electrical equipment and the ac power supply system; Thus, be beneficial to the maintenance of appliances power source structure, and the useful life of improving the electrical equipment battery.

Description of drawings

Fig. 1 is the circuit structure diagram of first embodiment of this Zener diode switching.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified:

In the embodiment shown in fig. 1, this Zener diode adapter comprises first input end 11, second input 12, first output 21, second output 22; Said first input end 11 links to each other through a lead that is serially connected with three Zener diodes 3 in the same way with first output 21; Said second input 12 also links to each other through a lead that is serially connected with three Zener diodes 3 in the same way with second output 22; And the negative pole of each said Zener diode 3 is jointly towards said first output 21, second output 22.

In addition, light-emitting diode 4 of parallel connection on each said Zener diode 3, said Light-Emitting Diode 4 is prepended to the housing outer surface of said Zener diode adapter; In the case, if each said Zener diode 3 is intact, then when normal the use; Pressure drop on each zener diode 3 can be lighted its pairing Light-Emitting Diode 4; If certain Zener diode 3 is during by irreversible puncture, then during operate as normal, there is not pressure drop on this Zener diode; Its pairing light-emitting diode is in the state that secretly goes out all the time, then can point out the replacing Zener diode.

Above-mentioned Zener diode adapter in use, after the appliance switch closure, at any one time; Zener diode 3 between said first input end 11, first output 21, the Zener diode 3 between perhaps said second input 12, second output 22 must have one the tunnel to be in the high back voltage state; As; If at the alternating current positive half period, the Zener diode 3 forwards energising between said first input end 11, first output 21, the Zener diode 3 between then said second input 12, second output 22 is in the high back voltage state; Otherwise the Zener diode 3 between said first input end 11, first output 21 is in the high back voltage state; This high back voltage will be broken through the reverse dead band voltage of Zener diode 3, make Zener diode be reversed conducting (reversible puncture), and at this moment, all Zener diodes 3 all are in low resistive state, can make the electrical equipment operate as normal; When electrical equipment cuts out, only there is little electric current to exist in the electrical equipment, at this moment; Electrical equipment is equivalent to a big resistance, most of voltage of AC power all is divided to the electrical equipment two ends, and the voltage on each Zener diode 3 reduces significantly; Thereby get into the voltage dead band, cause Zener diode 3 oppositely to end, so; Further reduced said little electric current, made the state that maintenance approaches to open circuit between electrical equipment and the ac power supply system, thus; Be beneficial to the maintenance of appliances power source structure, and the useful life of improving the electrical equipment battery.

The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
