Abstract
The utility model discloses a magnetic-control switch of dry-reed tube, and a controlling circuit is composed of a resistor, a diode trigger, a dry-reed tube, a bidirectional thyristor and an illuminating lamp which are connected together. Since the dry-reed tube controlled the illuminating lamp is adopted in the controlling circuit by the utility model, and the dry-reed tube is controlled by the magnetic stripe on a refrigerator door seal. When the door is open, the magnetic field around the dry-reed tube disappears, the normally-closed contact of the dry-reed tube is closed, the bidirectional thyristor is conducted, and the illuminating lamp is lighted. And the controlling of the magnetism in large current and high voltage is realized, and the power control of the utility model has the features of contactless, noncontact, small volume, low cost, convenient installation, etc.
Description
Technical field
The utility model belongs to switching device, relates in particular to a kind of tongue tube magnetic switch of refrigerator inside control illuminating lamp.
Background technology
At present, the refrigerator illuminating lamp all adopts the contact mechanical switch, because the high humidity environment of refrigerator, and its contact easy-to-rust and cause loose contact, the life-span is shorter, and push rod that it exposes or briquetting influences the aesthetic feeling of casing, and easily bump to break and damage by pressure.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of volume little, easy for installation, and the magnetic stripe that adopts refrigerator doors to seal up is controlled a kind of tongue tube magnetic switch of illuminating lamp.
The utility model is achieved through the following technical solutions:
A kind of tongue tube magnetic switch, described control circuit is made up of resistance, resistance, diac, tongue tube and bidirectional triode thyristor, wherein resistance and resistance are contacted, its tie point links to each other with diac one end, diac the other end link to each other with an end of tongue tube, the control utmost point G end of the other end of tongue tube and bidirectional triode thyristor links to each other; The other end of resistance links to each other with the anode A of bidirectional triode thyristor 1, draws the lead L that links to each other with power supply from its tie point, is in series with illuminating lamp on the lead L; The other end of resistance links to each other with the anode A of bidirectional triode thyristor 2, draws a lead N who links to each other with power supply from its tie point.
The utility model has the advantages that: owing to adopted tongue tube to control illuminating lamp in the utility model control circuit, and tongue tube is to control by the magnetic stripe that refrigerator doors is sealed up, magnetic field when door is opened around the tongue tube disappears, the normally-closed contact closure of tongue tube, the bidirectional triode thyristor conducting, illuminating lamp is lighted, thereby has realized the control of big electric current, high-tension magnetic, and power control contactless, do not contact, volume is little, cost is low, characteristics such as easy for installation.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 is the structural representation that the utility model is installed in refrigerator inside.
Embodiment
Embodiment: tongue tube magnetic switch as shown in Figure 1, it comprises control circuit and illuminating lamp, control circuit is made up of resistance 1, resistance 2, diac 3, tongue tube 4 and bidirectional triode thyristor 5, wherein resistance 1 is contacted with resistance 2, its tie point links to each other with diac 3 one ends, 3 the other end of diac links to each other with an end of tongue tube 4, and the other end of tongue tube 4 links to each other with the control utmost point G end of bidirectional triode thyristor 5; The other end of resistance 1 links to each other with the anode A 1 of bidirectional triode thyristor 5, draws the lead L that links to each other with power supply from its tie point, is in series with illuminating lamp 6 on the lead L; The other end of resistance 2 links to each other with the anode A 2 of bidirectional triode thyristor 5, draws a lead N who links to each other with power supply from its tie point.
Above-mentioned resistance 2 also can just replace with electric capacity.
Described tongue tube 4 also can be changed with the position of diac 3 and resistance 1, can realize the function of switch equally.
According to position shown in Figure 2, when refrigerator 8 foaming, tongue tube magnetic switch 9 imbedded in the frame on the case mouth during installation, also on top punch on the frame, the tongue tube magnetic control is opened 9 close and insert, use gland seal then.The termination of tongue tube magnetic switch 9 must be in door seals the interval of magnetic stripe 7 glands, and the end can not be blocked by other object.
The course of work is as follows:
When the door on the refrigerator 8 was closed, the magnetic stripe 7 at door envelope place disconnected the normally-closed contact of tongue tube 4, bidirectional triode thyristor 5 not conductings, and illuminating lamp 6 does not work.When the door on the refrigerator 8 when opening, the magnetic stripe 7 at door envelope place is away from tongue tube 4, its normally-closed contact closure, and bidirectional triode thyristor 5 conductings, illuminating lamp 6 is lighted.
Tongue tube magnetic switch of the present utility model also can be used for various storehouses door, or needs the place of burglar alarm, and its power also can be expanded.
