Embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of video camera switching device of optical fiber, as Fig. 1, Fig. 3, Fig. 4 and shown in Figure 5, this switching device shifter comprises: base 101 and loam cake 105, described loam cake 105 is installed on the described base 101, loam cake 105 is installed on this base 101 by screw 106 in the present embodiment, in other embodiment, also can install as the buckle mode by other.Described loam cake 105 is provided with an eyeglass window 111, is used to make cutoff filter or normal transparent optical filter to be positioned at this eyeglass window 111, and corresponding light is filtered.This device also comprises left electromagnet, the right electromagnet 103 that is installed on the described base 101, be equiped with slide block 109 between the described left and right sides electromagnet 103, be equiped with cutoff filter 107 and normal transparent optical filter 108 on the described slide block 109 side by side, two optical filters 107,108 also can be bonded on the slide block 109 by glue, also can be fixed on the slide block 109 by the mode of buckle.
The left and right sides of described slide block 109 is respectively arranged with permanent magnet 104, in the present embodiment, described base 101 is provided with groove, and left and right sides electromagnet 103 is buckled in this groove, in other embodiment, also can in other way this electromagnet 103 be fixed on the base 101.In the present embodiment, this permanent magnet 104 is fastened with glue in the both sides of slide block 109, among other embodiment, also can permanent magnet 104 be fixed on the slide block 109 by other modes.Described left electromagnet, right electromagnet 103, slide block 109, permanent magnet 104, cutoff filter 107 and normal transparent optical filter 108 are between described base 101 and described loam cake 105.Described base 101 is provided with chute, and the dual-side up and down of described slide block 109 is an arc, and dual-side slidably is stuck in the described chute up and down.When no power, remain on the rightmost state at the attractive force sliding block with iron core right electromagnet 103 right permanent magnet 104; During galvanization, left and right sides electromagnet 103 produces electromagnetic forces, at this moment, and product repulsive force between the permanent magnet 104 that former the right attracts mutually and the right electromagnet 103, and left electromagnet 103 and permanent magnet 104 produce attractive force simultaneously, so slide block 109 moves to the left side with regard to stressed; When slide block 109 moves to leftmost position, stop energising, under the attraction force acts of left permanent magnet 104 and the iron core of left electromagnet 103, slide block 109 will remain on this position always.Realized that the convenient of different eyeglasses switches.
In the present embodiment, further, also be provided with pcb board 102 on the described base 101, described pcb board 102 connects 110 described left and right sides electromagnet 103 by lead.Carry out the control of power on/off and providing of power supply by 102 pairs of left and right sides electromagnet of this pcb board 103, in other embodiment, also can carry out the control of power on/off and providing of power supply to left and right sides electromagnet 103 by other electron device.
In addition, in the switching device shifter that this embodiment provides, this electromagnet is concordant with the center line of permanent magnet, switching power when fully guaranteeing energising and the confining force fixedly the time; The slide block and the contact way of contact of all adopting circular arc and plane of base in level and vertical direction for linear contact, greatly reduce friction force when promptly realizing slide block movement, guarantee the smooth and easy of switching; All slipping planes of slide block and base contact, the mould aspect all adopts polishing, and loam cake is non-surface-treated stainless steel, greatly reduces the friction factor of slipping plane; Optical filter adopts ultrathin type, and (thickness T=0.3mm), reduced the weight of slide block has on the whole effectively reduced the friction force in the handoff procedure simultaneously; The gap width of slide block between base and loam cake is 0.3 ± 0.05, also reserved the space of expanded by heating in the time of smooth and easy the carrying out of guarantee switching.
