Abstract
The utility model discloses a steel pipe is used in the encapsulation of slab guide optical divider, including two units. Two unit width vary, second unit B's width slightly is greater than first unit A's width. The punching press has two bumps on each lateral wall of first unit A, each lateral wall of second unit B rotate upward and have two holes. Closely the buckle is together between first unit A and the second unit B. The utility model discloses a mechanical properties that the PLC optical divider encapsulation had been guaranteed in the use is and effectively reduced epoxy AB glue's use. The environment that this has not only practiced thrift former material protection has avoided a few peoples to contact the problem that the glue solution can produce slight skin hypersensitivity and sufferings for a long time moreover. Consequently the utility model discloses be fit for being applied to in optical divider's the equipment.
Description
Technical field

Background technology
Planar light shunt is a kind of based on quartz base plate integrated light guide optical power distribution devices, there is the advantages such as volume is little, working range is wide, reliability is high, point optical uniformity is good, be therefore widely used in connecting in EPON local and terminal device and realize the shunt of light signal.In the number of assembling steps that planar light shunt manufactures, stainless-steel tube is adopted to be used for the encapsulation of optical branching device assembly.
In optical branching device assembling inwall scribbled the larger steel pipe socket of the width of epoxy AB glue on the steel pipe that the width that plug is housed is less, reach bonding object.Epoxy AB glue smear the mechanical property requirements that improper meeting affects planar light shunt greatly.The buckle-type encapsulation of plane waveguide light shunt encapsulation steel pipe utilizes the elastic deformation of stainless steel self to ensure that the mechanical property of encapsulation; effectively reduce the use of epoxy AB glue, protect physical environment and avoid the problem that a few peoples' Long contact time glue can produce mild skin allergy and sufferings.
Prior art is difficult to the needs of people, in order to solve above-mentioned Problems existing, the utility model proposes a kind of buckle-type plane waveguide light shunt encapsulation steel pipe, it effectively ensure that and the mechanical property that plane waveguide light shunt encapsulates decreases the use of epoxy AB glue.
For realizing this technical purpose, the technical solution adopted in the utility model is: a kind of buckle-type plane waveguide light shunt encapsulation steel pipe, is made up of first module A and second unit B two parts.Each lateral wall upper punch of described first module A is pressed with two salient points, and the lateral wall of second unit B turns two holes.After described first module A is buckled in second unit B, both compact siro spinning technology together, meets the requirement to PLC optical branching device component package.
Further, described steel pipe adopts stainless steel material, and the thickness of stainless steel substrates is not more than 0.5mm.
Further, described bump size tolerance is 0.03mm.
Further, described hole dimension tolerance is 0.03mm.
Further, it is tolerance value 0.08mm that described perforation and the axis of salient point are positioned at diameter.
Further, the stand out of two described unit is less than 2 times of stainless steel thickness.
Compared with prior art, the utility model has following beneficial effect: the use of plane waveguide light shunt encapsulation steel pipe ensure that the mechanical property of PLC optical divider packaging.The optical branching device utilizing the method for packing of the utility model patent to produce carries out vibration test and impulse test, and its experimental result meets the requirement of optical branching device failtests completely.The utility model patent decreases the use of epoxy AB glue; Not only protect physical environment, and avoid problem that is that a few peoples' Long contact time glue can produce mild skin allergy and sufferings.One-piece construction is simple, practical, is easy to promote the use of.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Figure of description 1 ~ 5, in the utility model embodiment: a kind of buckle-type plane waveguide light shunt encapsulation steel pipe, is made up of first module A and second unit B two parts.Each lateral wall upper punch of described first module A is pressed with two salient points, and the lateral wall of second unit B turns two holes.After described first module A is buckled in second unit B, both compact siro spinning technology together, meets the requirement to PLC optical branching device component package.
Further, described steel pipe adopts stainless steel material, and the thickness of stainless steel substrates is not more than 0.5mm.
Further, described bump size tolerance is 0.03mm.
Further, described hole dimension tolerance is 0.03mm.
Further, it is tolerance value 0.08mm that described perforation and the axis of salient point are positioned at diameter.
Further, the stand out of two described unit is less than 2 times of stainless steel thickness.
The utility model, when designing, needs to cut out the stainless steel substrates of certain size according to the size of described unit A and unit B and determines the position of punching press salient point and perforation.Stainless steel tapping machine is utilized to bore a hole to the stainless steel substrates made for unit A, red needle and mould is utilized to carry out punching press to the stainless steel substrates made for unit B, obtain treated two kinds of stainless steel substrates, recycling sheet metal process process two kinds of stainless steel substrates obtain the shape as Fig. 2.
In described unit A and unit B, the position of salient point and perforation as shown in Figure 4, is determined the value of stainless steel substrates size and a, b according to actual needs, the stainless steel substrates cut is carried out salient point and perforation.
