Abstract
The utility model discloses an inductor that diamagnetism was disturbed, including the inductor body, the inductor body in the parallel placement have one to normally open tongue tube and a normal close tongue tube, fixed normal close magnet of lower extreme position fixedly connected with of having placed an iron sheet, normal close tongue tube between two reed pipes, the interface of normally opening the one end of tongue tube and normal close tongue tube, the other end is connected to the system respectively, the one side and the work magnet actuation of normally opening the tongue tube, the beneficial effect of the utility model: the tongue tube is normally opened in the magnet actuation that iron sheet in the inductor can shield on the normal close tongue tube, can shield the external world and be used for disturbing the magnetic field of normally opening the tongue tube, can effectively strengthen the interference immunity of security protection system, the simply easy installation of this money inductor, and interference immunity is good, can reduce the loss that brings because of the defect of security protection system.
Description
Technical field
The utility model relates to a kind of anti-theft device, particularly the inductor that disturbs of a kind of diamagnetism.
Background technology
Door magnetic on current security protection market, its principle of work is the dry reed switch often opened by magnet attraction, allows switch be in closure state, when opening door and window, sends alarm command after magnet and dry reed switch disconnect to system.Its shortcoming: as long as burglar is first adsorbed near dry reed switch with one block of strong magnetic, then open door and window, although the magnet now door and window installed has been thrown off, the strong magnetic of external force still adhesive dry reed switch, now switch has still been in closure state, so can not report to the police.
Utility model content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides the inductor that a kind of diamagnetism is disturbed.
To achieve these goals, the measure taked of the utility model:
A kind of inductor of diamagnetism interference, comprise sensor body, parallelly in described sensor body be placed with one and often open tongue tube and a normally closed tongue tube, between two reed pipes, fixed placement has one piece of iron plate, and the lower end position of normally closed tongue tube is fixedly connected with a normally closed magnet.
The described interface often opening one end of tongue tube and normally closed tongue tube, the other end is connected respectively to system, the described one side often opening tongue tube and work magnet attraction.
The beneficial effects of the utility model: the magnet attraction that the iron plate in inductor can shield on normally closed tongue tube often opens tongue tube, can shield extraneous for disturbing the magnetic field of often opening tongue tube, effectively can strengthen the anti-interference of safety-protection system, this money inductor is simple and easy to install, anti-interference is good, can reduce the loss that the defect because of safety-protection system is brought.

Fig. 1, structural representation of the present utility model.
Embodiment
A kind of inductor of diamagnetism interference, comprise sensor body 1, parallelly in described sensor body 1 be placed with one and often open tongue tube 2 and a normally closed tongue tube 3, between two reed pipes, 2,3 fixed placement have one piece of iron plate 4, and the lower end position of normally closed tongue tube 3 is fixedly connected with a normally closed magnet 5; Iron plate 4 is used for normally closed magnet 5 adhesive shielded on normally closed tongue tube 3 and often opens tongue tube 2, and shielding is extraneous for disturbing the magnetic field of often opening tongue tube 2.
The described interface 6 often opening one end of tongue tube 2 and normally closed tongue tube 3 is connected in series, and the other end 7 is connected respectively to system.
The described one side often opening tongue tube 2 and the adhesive of work magnet 8.
Often open tongue tube 2 by adhesive or disconnection with work magnet 8, send signal, to play the effects such as security alarm to system.
The simple change of those ordinary skill in the art and replacement are all within protection domain of the present utility model.
