Description

The adjustable power supply socket

The utility model belongs to a kind of electrical installation, the particularly a kind of general supply socket that can regulate watt level.

Household electrical appliance such as various desk lamps, pendent lamp, wall lamp, various insulating pot, electric chafing dish, electric wok go deep in the resident family quite widely, become the necessary article of daily life.Along with the raising of people's life, also more and more higher to the requirement of various household electrical appliance functions.As to lighting, wish that the brightness (thereby illumination) of lamp is adjustable, can satisfy the different requirements of different time to indoor light brightness, again can saves energy.And for example to electric wok, electric chafing dish etc., both having wished that initial the intensification wanted fast, and when boil or boil after temperature reduce maintenance low temperature a period of time again.Even, to add different temperature in gastronomical process different phases such as steaming, boil or burn stir-fry according to different food products requirement heating process process difference, could satisfy all good good results of color, smell and taste.And present most of household electrical appliance itself do not have power (thereby brightness, temperature etc.) regulatory function, and electric wok, lamp dimmer that has only minority etc. is equipped with special-purpose temperature adjustment, light modulating device.The structure of existing common power socket is roughly, have one group of group two hole or/and three hole jacks on the socket base plate, corresponding each jack fixedly is equipped with the socket shell fragment, and every group of socket shell fragment has lead connection of a usefulness, another connects with another lead again, is respectively live wire and zero line.Last socket shell fragment in the three hole jacks connects with the 3rd lead, Here it is public ground wire.Live wire, zero line and public ground wire connect with a plug, and plug is used to the civil power of pegging graft.When plug and civil power connection, then every group of socket shell fragment all constitutes supply socket, is the household electrical appliance power supplies.Device voltmeter and/or switch are also arranged on the socket base plate, constitute multi-functional combined power socket.Win board 250V 10A supply socket as the moral of Yongming Household Electric Appliance Plant, Electronic Instruments Factory, Beijing Univ. and Ningbo cause more than the Ningbo 90-MGB-C type of U.S. electronic apparatus factory Joint Production with combined power socket etc., but all do not have the power adjustments function.

The purpose of this utility model provides a kind of input voltage and fixes and the continuously adjustable universal power supply socket of electromotive power output, solves the power adjustments problem of the household electrical appliance that self do not have special-purpose adjusting device.

The utility model is to install a kind of electronic circuit with power adjustments function additional to realize on the structure foundation of original socket.Its structure comprises: have one group of one group of two hole or/and the socket base plate of three hole jacks, in the socket base plate the hard-wired socket shell fragment of corresponding jack, have the power line of plug etc.Have a socket shell fragment to connect as live wire with lead in every group of socket shell fragment, other has a socket shell fragment to connect as zero line with lead, and a socket shell fragment of every group of Three-hole socket shell fragment remainder is made the common ground line with the lead connection.These two holes are connected to power line again or/and all or part of of Three-hole socket shell fragment links with the power adjustments electronic circuit, constitute the adjustable power supply socket.Said power adjustments electronic circuit mainly is made up of regulating circuit, phase-shift circuit and regulating element, and regulating element is with the power adjustments knob mechanical attachment on the socket base plate.

Fig. 1 to Fig. 3 provides a kind of specific embodiment.

Fig. 1 is a kind of surface structure schematic diagram of the present utility model.

Fig. 2 is a kind of electrical schematic diagram of the present utility model.

Fig. 3 is a kind of line map of the power adjustments electronic circuit among Fig. 2.

As can be seen from Figure 1, the utility model is similar with existing supply socket.On socket base plate 1, have eight groups of jacks (certainly, the group number of jack can be less than or more than eight), they are respectively two circles, two

jacks

2 and 3, two side's two

jacks

4 and 5, two circle three

jacks

6 and 7, two side's three jacks 8 and 9.Correspondence is equipped with the socket shell fragment in each jack, and the socket shell fragment is represented with XS at Fig. 2, and one group of corresponding one group of socket shell fragment XS of jack, such as, circle two jacks 2 corresponding two socket shell fragment XS ₂, circle three jacks 7 corresponding three socket shell fragment XS ₇Or the like.The circuit of each socket shell fragment XS can be to connect like this---four groups of socket shell fragment XS are wherein arranged ₂, XS ₄, XS ₆, XS ₈, they do not connect with the power adjustments electronic circuit, directly are connected to power line (12), constitute the common power socket; Wherein other four groups of socket shell fragment XS ₃, XS ₅, XS ₇, XS ₉Connect with the power adjustments electronic circuit, be connected to power line (12) again, constitute the supply socket of adjustable power, the electrical equipment that supply and demand will be regulated watt level uses.Adjustable element WR is with power adjustments knob (11) mechanical attachment, so that in use, and rotary power adjusting knob (11) and changed adjustable element WR in the electronic circuit, thus changed the output power of partial socket.Among Fig. 1 10 is voltage or electric current or power on/off dial gauge, 12 power lines for the band plug.Among Fig. 2 13 is regulating circuit, and 14 is phase-shift circuit.

Shown in the power adjustments electronic circuit of Fig. 3, regulating circuit 13 mainly is by two bidirectional triode thyristor V ₂, V ₃And connect the three-terminal network of formation, wherein two ends connect respectively on the lead of shell fragment (the A point among Fig. 2 and Fig. 3) among the socket shell fragment XS of every group of power-adjustable and power line 12 (B point among Fig. 2 and Fig. 3), the 3rd end then with bidirectional trigger diode V ₁Connect bidirectional trigger diode V ₁Be used to trigger regulating circuit 13.Phase-shift circuit 14 is mainly by capacitance-resistance combination, as among Fig. 3 by resistance, R ₁, R ₂And capacitor C ₁, C ₂Constitute three-terminal network, a termination A point wherein, the other end connects the B point through regulating element WR, the 3rd end and bidirectional trigger diode V ₁Connect.

Regulating circuit and phase-shift circuit can also adopt the circuit of other form.

The utility model is to add a cover simply to have the electronic circuit of regulating power functions in original supply socket; The various electrical equipment that are suitable for the inactivity adjusting carry out temperature adjustment, light modulation (brightness), turn speed; When not needing too big power consumption, timely and appropriate discovery is regulated power and electrical energy saving; Because electrical power regulates continuously, adjustablely turn down greatly, bring convenience to use.In a word, the utlity model has simple in structure, power is adjustable continuously, highly versatile, advantages such as electricity saving and energy saving.
