Abstract
The utility model relates to the technical field of the sealing weld of a pipe body of a coaxial photoelectric device in photo-communication industries, in particular to a sealing weld positioning device for the pipe body of the coaxial photoelectric device. The sealing weld positioning device comprises an electrode cover; a cylindrical inner hole for simultaneously limiting the excircle of a base and the excircle of the pipe body is arranged in the center of the electrode cover; and the sealing weld positioning device is characterized in that the cylindrical inner hole is internally provided with a ceramic circular ring or is coated by a ceramic material. The sealing weld positioning device has the advantages of being capable of ensuring the concentricity between a TO-can (transistor outline-can) and the pipe body, avoiding the adhesion between the TO-can and the pipe body, fully ensuring the gas tightness of the TO-can and simultaneously being capable of preventing a series of problems such as unstable sealing weld of the pipe body, deformation of the pipe body, burrs of the inner wall of the electrode cover which are caused by the declining of insulation property.
Description
Technical field
The utility model relates to the body sealing technique field of axis light electrical part in the optic communication industry, especially a kind of axis light electrical part body soldering and sealing positioner.
Background technology
Body soldering and sealing is a step important process of axis light electrical part in the optical communication field, and this technology is welded on body on the base through the discharge mode of electric resistance welding securely.At present, the locate mode of body soldering and sealing mainly contains two kinds in the industry, first kind of locate mode: fixing body only, utilize the matched in clearance between the circle in metal cylindrical and the body of lens hood on the base again, and realize the coaxial positioning of the two; Second kind of locate mode: it is spacing that the electrode cap after utilizing surface anodization to handle is carried out the while to base cylindrical and body cylindrical.Yet; More than two kinds of locate modes all have hidden danger; To first kind of mode; Matched in clearance is prone to cause the metal outer wall and the inboard wall of tube body adhesion of lens hood when soldering and sealing is discharged, thereby can't guarantee that (a kind of cylindrical shell that is formed by base and lens hood encapsulation, inner sealing is also used nitrogen protection to TO-can.) air-tightness; For the second way, though the spacing electrode cap of surface anodization can guarantee the air-tightness of TO-can, still; Because the wearability of anodized surface is very poor, be prone to cause the anodized surface wearing and tearing in the soldering and sealing process, cause serious consequences such as electric leakage, burr; The intensity of the electrode cap of anodization simultaneously is not high; When soldering and sealing voltage is bigger than normal, be prone to cause the body distortion, influence the coupling clamping of photoelectric device.
Summary of the invention
The utility model has proposed a kind of axis light electrical part body soldering and sealing positioner to the deficiency of above-mentioned prior art, adopts this positioner; Both can guarantee the axiality of TO-can and body; Avoid the adhesion between the two, fully guarantee the air-tightness of TO-can, simultaneously; Can prevent that the body soldering and sealing that causes because of insulating properties decline is not firm, the body distortion, serial problems such as electrode cap inwall burr.
The utility model is for solving above technical problem; Following technical scheme is provided: a kind of axis light electrical part body soldering and sealing positioner; It comprises an electrode cap; There is a cylindrical bore that is used for spacing base cylindrical of while and body cylindrical the electrode cap center, and its difference is: said cylindrical bore built-in ceramic annulus or application ceramic material.
Compared with prior art, the utlity model has following advantage:
1, inboard ceramic material or the built-in ceramic annulus of adopting of electrode cap centre bore utilizes ceramic good insulation performance property, serial problems such as the body soldering and sealing that can avoid causing because of electric leakage is not firm, electrode cap inwall burr;
2, the inboard ceramic material that adopts of electrode cap centre bore utilizes the good wearability of pottery, can stop bad phenomenon such as body distortion;
3, ceramic endoporus is embraced base cylindrical and body cylindrical simultaneously, can guarantee the axiality between the two, the TO-can air-tightness problem that causes to avoid the lens hood adhesion;
4, the injection moulding manufacture craft of ceramic material is very ripe, especially, adopts built-in ceramic annulus scheme to be more convenient for processing, and has more versatility.
In a word, the serial hidden danger that the application of the utility model can stop to leak electricity in axis light device soldering and sealing process well and adhesion brings, the ratio of performance to price is high, and therefore wide application prospect is arranged.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the application structure sketch map of the utility model embodiment.
The specific embodiment
With concrete implementation the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment; Fig. 2 is the application structure sketch map of the utility model embodiment.
As shown in Figure 1, a kind of axis light electrical part body soldering and sealing positioner, it comprises an electrode cap 1; There is a cylindrical bore 1-1 who is used for spacing base 3 cylindricals of while and body 4 cylindricals electrode cap 1 center, cylindrical bore 1-1 built-in ceramic annulus 2 or application ceramic material, in a word; As long as guaranteeing the inside material of cylindrical bore 1-1 is pottery; Can realize the technical problem of the utility model, other parts of electrode cap or the pottery of same material, or plastics; Or metal, or the metal of surface anodization.As shown in Figure 2, the contact-making surface 3-4 between base 3 and the body 4 is arranged in cylindrical bore 1-1.
Electrode cap centre bore inboard is the implementation of ceramic material; Or spraying, or injection mo(u)lding, or built-in ceramic annulus 2; Promptly at first be processed into a ceramic annulus 2 with ceramic material; The mode that adopts some glue then or be press-fitted is enclosed within the outside of ceramic annulus 2 with electrode cap outer shroud 1, referring to Fig. 1.
During body soldering and sealing, ceramic endoporus must be embraced base cylindrical and body cylindrical simultaneously.
Electrode cap processing implementation in the utility model; Can adopt single injection-molded, also can be divided into two step manufacture crafts, promptly at first be processed into an electrode cap body 1 that has cylindrical bore with non-ceramic material; Pass through the mode of built-in ceramic annulus 2 or ceramic coated powder then; Form an electrode cap assembly, wherein, the built-in method of ceramic annulus can adopt a glue and press-fit to fix.
Localization method in the utility model is seen functional diagram (referring to Fig. 2); The electrode cap endoporus is embraced body 4 cylindricals and base 3 cylindricals simultaneously; This moment, body and base contact-making surface (plane of promptly discharging) were in ceramic ring; Wherein the last plane of base 3 must be protruded, and base 3 can full contact with the top electrode of welder during with assurance soldering and sealing.
In actual use, the upper-lower position of base 3, body 4 can exchange.
Above content is the further explain that combines concrete embodiment that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
