Abstract

The utility model relates to an anti-theft magnetic reed sensor. The utility model comprises a switch body, in which a magnetic reed pipe is arranged, and connected on a common circuit of a security circuit, and the spring leaf of the magnetic reed pipe is alternatively connected with the constantly closed circuit or the constantly opening circuit of the circuit system; a magnet, which is located at the position opposite to the outside of the switch body; a luminous element is connected on the constantly closed circuit of the security system in series. when the magnet is near to the switch body, the spring leaf of the magnetic reed pipe is absorbed away from the constantly closed circuit to present a broken circuit; when the magnet is deviated from the switch body, the spring leaf of the magnetic reed pipe is near to the constantly closed circuit to present a connected circuit, to enable the luminous element to perform the alarming function, therefore the whole circuit contains simpler element design, and further the failure occurrence opportunity is eliminated.

Description

Antitheft magnetic red sensor

Technical field

The utility model relates to a kind of antitheft magnetic red sensor, refers to a kind of antitheft magnetic red sensor that can only be connected in series light-emitting component on the normally closed circuit of safety system especially.

Background technology

Fig. 1 is the accompanying drawing 3 of No. 322991 patent in Taiwan, the series circuit of a LED (light-emitting diode) 108 with a resistance 109 compositions that it is characterized in that on the contact of the inner magnetic reed switch 106 outer signal power lines of magnetic red perceptron cross-over connection.

This antitheft magnetic red perceptron adopts the design of " series circuit that gives cross-over connection one LED light-emitting diode and a resistance on the contact of the inner magnetic reed switch outer signal of magnetic red perceptron power line ", its clearer accompanying drawing, please consult Fig. 1 and Fig. 2 simultaneously in the lump, because this resistance 109 is set suitable resistance value according to each host computer system, make signal code whether " in the main control system that in this set point, also can reflux " by the magnetic red contact, can involve this LED 108 and whether send light, so that detect the whether normal operation of magnetic red perceptron, and can find failure situations ahead of time and can be overhauled recovery in good time.Only this kind circuit structure needs more element, and makes set point for this resistance 109 in advance, if this resistance 109 has fault then can cause the running of magnetic red perceptron to lose efficacy.

Thereby, the circuit structure of employing " cross-over connection LED series resistor on normally opened track circuit ", still being difficult to exempt resistance value needs setting in advance to reach puzzlements such as the fault generation is probably arranged, and necessity of being improved is arranged then.

Summary of the invention

Because the shortcoming of aforementioned prior art, the purpose of this utility model provides a kind of antitheft magnetic red sensor, and its circuit simply can be eliminated the fault chance of occurrence, can fully reach the anti-theft warning effect.

For achieving the above object, the utility model by the following technical solutions:

A kind of antitheft magnetic red sensor, it comprises:

A switch body, it is provided with a magnetic red pipe, and this magnetic red pipe is connected in the shared line of a safety system, and this magnetic red pipe reed selectively is connected with the normally closed circuit or the normally opened track circuit of this safety system;

A magnetite, it is positioned at corresponding on the position outside the described switch body;

When described magnetite when the described switch body, described magnetic red pipe reed is away from normally closed circuit by magnetic to open circuit; When described magnetite departed from described switch body, described magnetic red pipe reed was pressed close to normally closed circuit and is path.

Be connected in series light-emitting component on the normally closed circuit of described safety system.

Described light-emitting component is light-emitting diode or bulb.

Advantage of the present utility model is, directly be serially connected in by light-emitting component on the normally closed circuit of safety system, be with signal power source and connect, also need not to set resistance value because of detecting unusually, so can make integrated circuit on element design, more simplify, eliminate the fault chance of occurrence.

Description of drawings

Fig. 1 is the accompanying drawing 3 of No. 322991 patent in Taiwan.

Fig. 2 is according to Fig. 1 will " the right Hou of LED series resistor be serially connected with the circuit diagram on the normally closed circuit.

Fig. 3 is the stereo appearance figure of switch body of the present utility model and magnetite.

Fig. 4 is for only being connected in series the circuit diagram of one group of light-emitting component (LED) on the normally closed circuit of the present utility model.

Fig. 5 is for only being connected in series the circuit diagram of one group of light-emitting component (bulb) on the normally closed circuit of the present utility model.

Embodiment

Below, lift preferred embodiment of the present utility model now, and conjunction with figs. is described in further detail.

See also Fig. 3, the utility model mainly is made up of a switch body 1 and a magnetite 2, both keep corresponding states, wherein ccontaining with a housing respectively, this switch body 1 is installed on the doorframe (and window frame, the moving rolling door frame of electric hand, manual rolling door frame, window type cold air or separate cold or the like reach other protection subject matter of applicating adn implementing according to this), except that inside is provided with circuit, outside more the electric wire of circuit being extended; This magnetite 2 is installed on the door-plate (window, electronic or manual rolling door).

See also Fig. 4 and Fig. 5.Switch body 1 is provided with a magnetic red pipe reed 11, magnetic red pipe reed 11 is connected in shared (COM) circuit 121 of a safety system 12, and this magnetic red pipe reed 11 is selected normally closed (N.C.) circuit 122 of a ground and this safety system 12 or often opened (N.O.) circuit 123 and is connected; Magnetite 2 is corresponding on the position outside this switch body 1.Therefore, when magnetite 2 during near switch body 1, magnetic red pipe reed 11 is subjected to the magnetic effect and is off state away from normally closed (N.C.) circuit 122; Otherwise when magnetite 2 departed from switch body 1, magnetic red pipe reed 11 was pressed close to normally closed (N.C.) circuit 122 and is path (ON) state.

Light-emitting component 13 on normally closed (N.C.) circuit 122 of this safety system 12 can select only to be serially connected with LED or bulb or the like, and for example the light-emitting component 13 of Fig. 4 is LED, and the light-emitting component 13 of Fig. 5 is a bulb.

Form by above-mentioned member, on normally closed (N.C.) of safety system circuit 122, be serially connected with light-emitting component 13, use (that is door shuts away) in the time of to make magnetite 2 near switch body 1, magnetic red pipe reed 11 is subjected to the magnetic effect and is off state away from normally closed (N.C.) circuit 122, this moment light-emitting component 13 can be not shinny (that is LED or bulb extinguish); Otherwise, when magnetite 2 departs from switch body 1 (that is door is opened), magnetic red pipe reed 11 is pressed close to normally closed (N.C.) circuit 122 and is channel status, this moment, light-emitting component 13 meetings were shinny, that is LED or bulb light, send warning function, so integrated circuit is not only possessed the element design of more simplifying, and then eliminates the fault chance of occurrence.

Though the utility model above-mentioned preferred embodiment of mat is described in detail, only the above only is familiar with this skill person and can be easier to understand the utility model for making, and non-limiting the utility model practical range.

So all equalizations of doing according to described shape structural feature of the utility model claim and spirit change and modify, and all should be contained in the claim of the present utility model.
