The fixture 120 is used to fix optical fiber 101.
Specifically, the fixture 120 clamps the optical fiber 101 through the through hole, realizes the fixation of the optical fiber 101.
The fixture 120 is fixed in the hollow via-hole, thus the optical fiber 101 by the fixture 120 realize with it is described
Being fixedly connected between shell.
In the present embodiment, the fixture 120 is the cylinder with centre bore, and the centre bore is the through hole,
That is, the through hole and the coaxial setting of the fixture 120.This way can make the optical fiber 101 in the through hole and institute
The coaxial setting of fixture 120 is stated, so as to reduce the use difficulty of the fibre-optical splice, is conducive to improving optical coupling efficiency.
As shown in Figure 4 and Figure 5, in the present embodiment, the fibre-optical splice is used to insert in metal installation base 200, the gold
The jack of insertion optical fiber is provided with category mounting seat 200.In order that the fibre-optical splice can realize that inserting the metal installs

In order that eccentric light 130 as much as possible realizes transmission, the light transmittance of the material of the fixture 120 should not be too
It is little.
If the light transmittance of the material of the fixture 120 is too little, it is unfavorable for realizing the transmission of eccentric light 130, may
Increase eccentric light 130 possibility that is reflected and being projected to front end optical system, increase the impaired possibility of optical system；Also it is unfavorable
In the refraction of eccentric light 130, the absorption of the light at fixture 120 and the contact position of optical fiber 101 of eccentric light 130 can be increased
And reflection, the accumulation of the end heat of optical fiber 101 may be increased, increase the possibility that optical fiber 101 is burned out.Specifically, this enforcement
In example, the light transmittance of the fixture material is more than or equal to 85%.
In addition the fixture 120 is additionally operable to realize that heat is dissipated.The fixture 120 is used to improve the fibre-optical splice
Heat-sinking capability, be conducive to improving the elevated problem in the end of optical fiber 101, advantageously reduce the appearance that optical fiber 101 is burned out phenomenon.
And, with the transmission of eccentric light 130, the energy of eccentric light 130 that the fixture 120 absorbs reduces, and is also beneficial to drop

It should be noted that the wall thickness d of the fixture 120 also can make to the fixture translucent effect and radiating effect
Into impact.If the wall thickness d of the fixture 120 is too little, the metal installation base 200 and the light of eccentric light 130 is absorbed
Fine 101 distance is too near, is unfavorable for improving the too high problem of the temperature of the optical fiber 101；If the wall thickness d of the fixture 120
It is too big, then easily cause waste of material, increase the problem of technology difficulty.Specifically, in the present embodiment, the fixture 120
External diameter is in the range of 2.85mm to 3.49mm, so the wall thickness d of the fixture 120 is in the range of 2.17mm to 3.07mm.
