Abstract
The utility model relates to a switch controlled by magnetic field. The utility model is characterized in that the utility model is composed of an upper contact sheet, a reed, and a lower contact sheet; the reed is arranged between the upper contact sheet and the lower contact sheet; one end part of the reed is fixedly provided with at least one permanent magnet. The utility model has the selectivity of the value of the magnetic field strength and the direction of the outer magnetic field and has three operating states of 'switch on 1', 'switch on 2 ', and ' open circuit'.
Description
The utility model belongs to field of electrical components.
Tongue tube is the at present widely used switch that is subjected to magnetic field control, and when the external world had certain magnetic field intensity, the two metal sheets in the tongue tube was that joining becomes on-state; When the external magnetic field weak strength can not make in the tongue tube two metal sheets joining, tongue tube then became open-circuit condition.Because tongue tube has only " open circuit " and " connection " two kinds of operating states, magnetic direction there is not selectivity, thereby in the occasion of some special applications, for example: under external magnetic field size and Orientation change at random condition, require that switch element is corresponding to have " connecting 1 ", " connecting 2 " and " open circuit " three kinds of operating states, so that when picking up the information of external magnetic field size and Orientation, tongue tube just can not directly use.
The purpose of this utility model is to manufacture and design a kind of switch that is subjected to magnetic field control, this switch that the is subjected to magnetic field control size and Orientation of the magnetic field intensity in magnetic field to external world has selectivity, and has " connecting 1 ", " connecting 2 " and " open circuit " three kinds of operating states.
The purpose of this utility model reaches like this: a kind of switch that is subjected to magnetic field control, of the present utility model being characterised in that: by being formed with fixing last contact (3), reed (4) and the following contact (5) also adjacent to each other together of insulating material, described reed (4) is positioned between contact (3) and the following contact (5) and an end is fixed with an above permanent magnet (7).Last contact (3), reed (4) and following contact (5) are made with the nonmagnetic metal sheet.
The utility model of taking above measure size and Orientation of the magnetic field intensity in magnetic field to external world has selectivity, and has " connecting 1 ", " connecting 2 " and " open circuit " three kinds of operating states.
In conjunction with the accompanying drawings the utility model is described in further detail again below:
Accompanying drawing 1 is the structure chart of the utility model embodiment;
Accompanying drawing 2 is installation diagrams of the utility model embodiment.
With reference to above accompanying drawing.From accompanying drawing 1 as can be seen, embodiment of the present utility model utilizes insulated bolt (1), insulation gasket ring (2) and nut (6) will go up contact (3), reed (4) and following contact (5) and is fixed together, the tail end of reed (4) is fixed with a permanent magnet (7), also can increase the quantity of permanent magnet (7), can improve sensitivity like this, but the direction of their magnetic poles wants consistent.Last contact (3), reed (4) and following contact (5) generally will with nonmagnetic metal book sheet for example phosphorus bronze sheet make.The utility model of above structure, the selection that can make operating state according to the magnitude of field intensity and the direction of external magnetic field.For example: when the magnetic field intensity of external magnetic field is 0, be in " open circuit " state; When the magnetic field intensity of external magnetic field reaches certain value and direction when consistent with the magnetic direction of permanent magnet (7), reed (4) be subjected to permanent magnet (7) to drive upwards contact (3) becomes " connecting 1 " operating state near until joining; When the magnetic field intensity of external magnetic field reaches the magnetic direction of certain value and direction and permanent magnet (7) when opposite, reed (4) is subjected to permanent magnet (7) to drive downward contact (5) near until joining, becomes " connecting 2 " operating state.Lead is connected the also suitable encapsulation of contact (3), reed (4) and following contact (5) can become a practical switch that is subjected to magnetic field control.Accompanying drawing 2 has at length provided the installation diagram of the utility model embodiment, is convenient to bending in order to make reed (4), and both sides, approximate mid-section position have hollowed out partly material.Except use embodiment with the fixing method of insulated bolt, the bonding method of also available insulation will go up contact (3), reed (4) and following contact (5) and be fixed together.Below provide the utility model parameter once experimental design again: going up contact (3) and following contact (4) is that 0.18 millimeter phosphorus bronze sheet is done 20 millimeters of growth with thickness, wide 4 millimeters, reed (4) is that 0.18 millimeter phosphorus bronze sheet is made with thickness also, long 30 millimeters, wide 4 millimeters, tail end cementation one block is long-pending to be 5 * 5 * 3mm
3The NdFeB rear-earth permanent magnet.Reed (4) all is 1 millimeter with the distance of last contact (3) and following contact (5), the utility model of above parameter, and the employing volume is 10 * 10 * 10mm
3The NdFeB rear-earth permanent magnet detect as the external magnetic field source, can make reliable reaction at distance the utility model below 10 millimeters, directly apply to picking up signal and automatically control.
