Description

Four electrode welding device of optical fiber splicer

Technical field

A kind of electrode welding device is the utility model is related to, more particularly to a kind of four electrode welding device of optical fiber splicer.

Background technology

Optical fiber splicer is produced while high-voltage arc melts two profile of optic fibre with high accuracy fortune using two electrode bars 1 Motivation structure, which gently promotes, allows two optical fiber to be fused into one, and most of fibre diameter is 80um~125um (not including coat), It is as shown in Figure 1 that arc discharge area 3 melts above-mentioned 2 section disposition of optical fiber.

However, some application requirement fibre diameters such as high-capacity optical fiber laser reach on 1mm, common welder It will cannot heat the optical fiber of 200um, the technology in the existing big fine footpath of hot melt, mainly resistance wire or laser heating, for big straight The optical fiber in footpath, the medium character of optical fiber material can make arc discharge area 3 surround fibre-optical bending, rather than by the whole of optical fiber 2 A circumference parcel, as shown in Figure 2；But the above method may cause the non-uniform heat flux of optical fiber, and cause welding to fail.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of optical fiber welding simple in structure, improving welding setting ratio Pick four electrode welding devices.

In order to solve the above technical problems, the utility model provides a kind of four electrode welding device of optical fiber splicer；

Including four electrode bars, four rectangular arrangements of electrode bar, four electrode bar center lines all in same plane, The extended line of four electrode bar center lines intersects at a point, and the tip of each electrode bar all points to this intersection point；

After four electrode bars are powered, arc discharge area is produced between the tip of four electrode bars.

After such structure, the arc discharge area weldable one of four electrode welding device of this optical fiber splicer generation Root jumbo fiber or multifiber, and the slight fluctuations in the external world can be kept out, four electrode welding device of this optical fiber splicer is arranged on Partially or fully in vacuum, since the elimination (or reduction) of convection current additionally provides the isothermal scope of the argon-arc plasma field of enhancing, with showing There is Technical comparing, in the case where the temperature from plasma rises (under atmospheric pressure), generate upward slight fluctuations, its The Ion paths between electrode can be destroyed, which will shake and extinguish in atmosphere plasma.

For the clearer technology contents for understanding the utility model, below by four electrode welding device of this optical fiber splicer Referred to as this electrode welding device.

Four square arrangements of electrode bar of this electrode welding device, each electrode rod outside diameter are 2mm, and any two is electric Pole rod minimum spacing is 4mm；After such structure, the distribution of electrode bar is more reasonable, and the arc discharge area of release is more Tend towards stability.

Brief description of the drawings

Fig. 1 is normal optical fiber weld job figure in the prior art.

Fig. 2 is large-diameter fibre-optical weld job figure in the prior art.

Fig. 3 is the usage state diagram of this electrode welding device.

Embodiment

As shown in Figure 3

This electrode welding device includes four electrode bars 1, four 1 square arrangements of electrode bar, four 1 centers of electrode bar All in same vertical plane, the extended line of four 1 center lines of electrode bar intersects at a point line, the tip of each electrode bar 1 This intersection point is directed toward, each 1 outside diameter of electrode bar is 2mm, and 1 minimum spacing of any two electrode bar is 4mm.

In use, four electrode bars 1 are powered, arc discharge area 3, major diameter are produced between the tip of four electrode bars 1 2 end face of optical fiber is placed in arc discharge area 3.

Above-described is only a kind of embodiment of the utility model, it is noted that for the ordinary skill of this area For personnel, on the premise of the utility model principle is not departed from, some variations and modifications can also be made, these also should be regarded as Belong to the scope of protection of the utility model.
