Description
Technical field
The utility model relates to a kind of switch, especially one day and night optical-filter switcher.
Background technology
For meeting the demand of taking in the environment of dark, in capture apparatus, all can be provided with optical-filter switcher, this optical-filter switcher can make capture apparatus carry out daytime screening-mode and shooting at night pattern between switching.Existing switch, coil can not be controlled the magnetic induction density that iron core produces well and be utilized, and, because the magnetic field intensity of magnet is more weak, make the control of active force part to rocking handle be difficult to perform to optimum efficiency.
Summary of the invention
The purpose of this utility model is to provide one day and night optical-filter switcher, realizes being controlled produced magnetic induction density and utilizing, make magnetic field intensity reach optimum efficiency by the iron core in control switch, coil.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: one is optical-filter switcher day and night, comprise cover plate, base, lens mount, magnet, pulling-on piece, cover plate is arranged on the upper surface of base, lens mount is arranged on the lower surface of base, magnet is arranged on the side in base, one side of magnet is provided with pcb board, pcb board is provided with electric wire and the Interface Terminal of protuberate basic unit, pulling-on piece is arranged on the middle part in base, pulling-on piece is provided with glass sheet, it is characterized in that: the outside of described magnet is provided with U-shaped sheet metal, the top symmetry of U-shaped sheet metal is wound with coil, magnet is provided with rocking handle by iron core, the top of rocking handle is connected with the chute of pulling-on piece.
Improvement to technique scheme: the coil on described U-shaped sheet metal top to be resistance the be coil of 30 ohm.
Further improvement to technique scheme: the thickness of described U-shaped sheet metal is 1.0mm, and material is SPCC material.
Improving further again technique scheme: the diameter of described iron core is 0.62mm, is provided with the spacing of 0.1mm between magnet and U-shaped sheet metal.
Beneficial effect:
One described in the utility model day and night optical-filter switcher, by control iron core in switch size, choose the specification that coil adopts and realize being controlled produced magnetic induction density and utilizing.And by Gauss's value of controlling magnet and the distance of magnet and iron core, make magnetic field intensity reach optimum efficiency.
Accompanying drawing explanation
Fig. 1 is explosive view of the present utility model.
Fig. 2 is the structural representation in base.
Embodiment
As Fig. 1, the utility model one day and night optical-filter switcher shown in Fig. 2, comprise cover plate 1, base 5, lens mount 6, magnet 12, pulling-on piece 4, cover plate 1 is arranged on the upper surface of base 5, lens mount 6 is arranged on the lower surface of base 5, magnet 12 is arranged on the side in base 5, one side of magnet 12 is provided with pcb board 8, pcb board 8 is provided with electric wire and the Interface Terminal 7 of protuberate basic unit 5, pulling-on piece 4 is arranged on the middle part in base 5, pulling-on piece 4 is provided with red, white glass sheet 2, 3, the outside of described magnet 12 is provided with U-iron sheet 11, the top symmetry of U-iron sheet 11 is wound with coil 13, magnet 12 is provided with rocking handle 9 by iron core 10, the top of rocking handle 9 is connected with the chute of pulling-on piece 4.
Principle of work: active force part adopts thickness: 1.0mm, and material: SPCC, shape is " U " iron plate of shape, be that the coil of 30 ohm (uses spooling equipment coiling by resistance, its apparent size can be controlled, the number of turn) be fixed on " U " shape iron plate, iron plate port is generated an electromagnetic field when being energized
(inductance value L(μ H)=(0.08 × D × D × N × N) ÷ (3 × D+9 × W+10 × H), D------coil diameter N------coil turn d-----wire diameter H----coil height W----coil width
),the direction in magnetic field can control by regulating the signal of reversal; The iron core of 0.62mm is adopted to fix the position of permanent magnet from power section, the spacing of 0.1mm is kept with " U " shape iron plate, permanent magnet is radial magnetizing, its magnetic field intensity 1200GS, reaches the effect of waving by active force part to the rocking handle that the control from power section reaches fixing on the permanent magnet.
