Description
[technical field]
This utility model relates to a kind of microsphere pipe cap, particularly to a kind of optical communication microsphere pipe cap.
[background technology]
In fiber optic communication field, optical transceiving device generally uses the optical element such as globe lens and non-globe lens as coupling
Element carries out optical focus, the most also needs that lens and supporting structure are carried out installation and is fixedly connected, solid to reach mechanical location
Fixed and hermetic closed purpose.Optical window encapsulation technology plays vital effect to the normal work of photoelectric device, impact
Optical window sealing technology is mainly the interconnection technique between shell and lens.Along with photoelectric device is to the air-tightness of sealing-in assembly and can
Require more and more higher, frequently with the form of level Hermetic Package, to increase the long-term reliability of device by property.
Current existing lens optical window forming technique mainly has cold-formed lens, molds non-globe lens, injection mo(u)lding
Lens etc., connection technique the most generally uses low temperature glass solder sealing-in, soldering sealing-in, the technique such as gluing to realize.It is cold worked into
Type glass be glass is used car, grind, the mode such as rolling is processed as design size, complex process, efficiency is low；Molding non-globe lens is
By molded at the mould inner mould designed after glass melting, can accurately realize Glass Design face type, but this technique is for work
Skill equipment, Mold Making require the highest, and difficulty is relatively big, causes cost of manufacture higher, and the most domestic not yet have this technical products
Occur；Lens injection mo(u)lding is then plastic part, with low cost, but operating temperature range is narrow, has that intensity is low, the life-span
The defects such as short, poor reliability, luminous power are limited.
And low temperature glass welding is to be welded on supporting structure by the glass optical window of molding with solder, this process warm
Degree, less than the softening temperature of light window glass, changes thus without the face type causing glass optical window；But glass solder and supporting construction
Firm welding very poor, cause the fastness being connected between lens optical window and package casing the most very poor, lens optical window easily exists
Come off during use, be especially applied to problem time on the device of those self existence vibrations the most prominent；Gluing work
Skill then uses adhesive means to be bonded on supporting structure by the glass optical window of molding, and its shortcoming mainly adhesive means causes
Linking intensity is poor, the life-span is short and the integrity problem such as organic contamination；Soldering sealing-in is by formed glass light with low-temperature alloy solder
Window is welded on supporting structure, and this technique needs the solder side of formed glass optical window carries out pretreatment of metallizing, and technique is multiple
Miscellaneous and high to process control needs, cost of manufacture is high.
[utility model content]
Main purpose of the present utility model be to provide one by glass bead can improve glass solder and metalwork it
Between contact area, thus increase the optical communication microsphere pipe cap of the bond strength between glass solder and metalwork.
For achieving the above object, the technical scheme that this utility model is taked is:
A kind of optical communication microsphere pipe cap, including the cap body being made up of metal material, the end of cap body is provided with glass bead, cap body
Lower edge position be provided with convex edge, convex edge is arranged on the lateral wall, lower edge position of cap body；The bottom of convex edge is provided with projection,
The inside of cap body is provided with cavity；Low temperature glass solder is arranged on the position, lateral wall of glass bead.
Further, it is provided with microflute between described cap body and low temperature glass solder.Further, microflute is less groove knot
Structure.
Compared with prior art, this utility model has the advantages that and can improve glass solder by glass bead
And the contact area between metalwork, thus increase the bond strength between glass solder and metalwork；And can by glass bead
To reach guide-lighting effect.
[accompanying drawing explanation]
Fig. 1 is the structural representation of this utility model optical communication microsphere pipe cap.Fig. 2 is this utility model optical communication microsphere
The side view of pipe cap.
Fig. 3 is A-A profile in Fig. 2.
[detailed description of the invention]
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, under
Face combines detailed description of the invention, and this utility model is expanded on further.
As shown in Fig. 1 to Fig. 3, a kind of optical communication microsphere pipe cap, including the cap body 1 being made up of metal material, cap body
The end of 1 is provided with glass bead 2, and the lower edge position of cap body 1 is provided with convex edge 3, and convex edge 3 is arranged on cap body 1
Lateral wall, lower edge position；The bottom of convex edge 3 is provided with projection 4, and the inside of cap body 1 is provided with cavity 6；Cap body 1
Top is provided with low temperature glass solder 7, and low temperature glass solder 7 is arranged on the position, lateral wall of glass bead 2；Glass bead 2
For spherical form, between cap body 1 and low temperature glass solder 7, it is provided with microflute 8；Microflute 8 is less groove structure.
This utility model optical communication microsphere pipe cap, can be improved between glass solder and metalwork by glass bead 2
Contact area, thus increase the bond strength between glass solder and metalwork；And guide-lighting work can be reached by glass bead 2
With.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also
Have various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model
Claimed scope is defined by appending claims and equivalent thereof.
