Abstract
The utility model relates to a non-rubber polarizing related optical isolator, including an outer ring, a support installed at both ends of the outer ring; an optical component composed of an optical element and a spacer is provided between two supports via a pin bolt; a welding hole is provided on the cylinder surface of the outer ring, and the joint of the outer ring and the support is welded through the welding hole. This optical isolator fixes each component through the mechanical structure of metal component, and adopts welding flux to weld and fix the support and the outer ring without using organic adhesive to paste each component, thereby enhancing the reliability, stability and service life of the optical isolator.
Description
The utility model relates to optical device, more particularly, relates to a kind of no glue polarization relative photo isolator.
The optoisolator of prior art is to connect and fix each element with organic gel in the mill always, when adopting this method, organic gel aging distortion in use can influence optoisolator reliability of products, stability and serviceable life inevitably, especially when this optoisolator is used for deep-sea, plateau, rugged surroundings such as aerial, the existence of organic gel may make optoisolator stability and serviceable life the aspect can not meet the demands.
The purpose of this utility model is, a kind of novel optoisolator is provided, can overcome the defective that existing use glue fixes the optoisolator of each element, can be applied in and comprise that deep-sea, plateau, harsh and unforgiving environments such as aerial are down and maintain good reliability, stability and serviceable life.
The purpose of this utility model is to realize like this, construct a kind of no glue polarization relative photo isolator, it is characterized in that, comprise outer sleeve, be contained in the bearing at described outer sleeve two ends, between described two bearings, the optical module of being made up of optical element and pad is housed by pin, have welding hole on the described outer sleeve cylinder,, be welded to connect at described outer sleeve and bearing junction by described welding hole.
In the no glue polarization relative photo isolator that provides according to the utility model, described number of pins can be two or three, on the described outer sleeve cylinder to two or three welding holes should be arranged, to two or three pin holes should be arranged, the correspondence position of each described pad has two or three pin bayonet socket or pin holes on each described bearing.
In the no glue polarization relative photo isolator that provides according to the utility model, described optical element comprises the faraday optical rotation plate of a rectangle and two rectangle polaroids of both sides thereof, is arranged with pad between each optical element.The faraday optical rotation plate of all right two rectangles of described optical element and three rectangle polaroids of middle and both sides thereof are arranged with pad between each optical element.
In the no glue polarization relative photo isolator that provides according to the utility model, comprise that also two centers that are stuck in described bearing both ends of the surface have the capping of light hole.
In the no glue polarization relative photo isolator that provides according to the utility model, can also replace described capping with jump ring, described jump ring comprises that two centers that are stuck in described bearing both ends of the surface have the capping of light hole and connect the connecting portion of described two cappings.
Implement the no glue polarization relative photo isolator that the utility model provides, adopt scolder that bearing and outer sleeve welding is fixing when fixing each element by physical construction, do not adopt bonding each element of organic gel, overcome the above-mentioned defective of prior art, increased reliability, stability and the serviceable life of optoisolator.
Below in conjunction with drawings and Examples, further specify characteristics of the present utility model, in the accompanying drawing:
Fig. 1 is the schematic appearance of no glue polarization relative photo isolator of the present utility model;
Fig. 2 is the A-A cut-open view of the optoisolator of one pole shown in Fig. 1;
Fig. 3 is the assembling process synoptic diagram of the optoisolator of one pole shown in Fig. 1;
Fig. 4 is the structural representation that the utility model does not have the capping in the glue polarization relative photo isolator.
The finished product outward appearance of the no glue polarization relative photo isolator that the utility model provides as shown in Figure 1, its A-A analyses and observe effect as shown in Figure 2, as can be seen, this no glue polarization relative photo isolator comprises side supports 2 and 3 from Fig. 2 and Fig. 3; Be contained in optical elements in described two bearings 2 and 3 comprise a faraday optical rotation plate 6, at two polaroids 5 of faraday optical rotation plate 6 both sides; Between described three optical elements, play two pads 4 of buffer action.Be provided with two pin holes at each bearing, link together by two pins 7 between the bearing 2,3; Be provided with the pin bayonet socket corresponding with pin 7 on pad 4, pin 7 also plays the effect of fixing described pad 4.
After described bearing 2,3, pad 4 and optical element 5,6 linked together by pin 7, be stuck on the both ends of the surface of bearing 2,3 with two cappings 9 that cooperate with the end face of bearing 2,3 again, by outer sleeve 1 above-mentioned each element all be enclosed within its inside at last.
In the enforcement, also can by outer sleeve 1 jump ring 8 and other each element all be enclosed within its inside at last with being fixedly connected to form the jump ring 8 that is stuck on described bearing 2,3 both ends of the surface between two cappings 9.
Wherein, but described outer sleeve 1, bearing 2,3 and pin 7 are made for weld metal, as can be seen from the figure, described bearing 2,3 and pad 4 centers have light hole, two circular weld holes 10 that have symmetry on the cylinder of described outer sleeve 1 are weldingly fixed on together by scolder 11 at described welding hole 10 places between the described collar 1, bearing 2,3 and the pin 7.
Wherein, optical element can also be other assembled state, for example can be the faraday optical rotation plate of two rectangles and three rectangle polaroids of middle and both sides thereof, is arranged with pad between each optical element.
In the enforcement, number of pins can be two, also can be three, on the described outer sleeve cylinder to three welding holes should be arranged, on each described bearing to three pin holes being arranged, three pin bayonet sockets of the correspondence position of each described pad or pin hole.
The no glue polarization relative photo isolator that adopts the utility model to provide no matter whether incident light is polarized light, is linearly polarized light through the emergent light behind this optoisolator.Adopt scolder that bearing and outer sleeve welding is fixing when this optoisolator is fixed each element by physical construction, do not adopt bonding each element of organic gel, increased reliability, stability and the serviceable life of optoisolator.
