Present invention process flow process:
1 is connected with the adhesive curing of bare fibre point by draw-in groove lock pin, grinds to form semi-manufacture two.See Figure 27.
Semi-manufacture two gluing is inserted case shell by 2, and is pressed into plastic plug, and semi-manufacture two are fixedly connected with case shell;
V-shaped groove aluminium flake is loaded plastic case shell from wire Block direction by 3;
Packaged for wire cartonning shell afterbody is pressed into plastic plug by 4, makes case shell be fixedly connected with wire block;
5 put metal clip spring, composition semi-manufacture one;
6 by semi-manufacture one spring on wire block place cover, then puts into inner casing;
Spring base is loaded inner casing afterbody by 7 again;
Optical fiber is first peelled off cortex and coat by 8, puts into solidus groove and covers tightly gland, make optical fiber and solidus flute profile integral, and cut optical fiber by length requirement;
The optical fiber cut penetrates from spring base afterbody with solidus groove by 9 together, and the projection that the hook of solidus groove end hangs up wire block tightens up;
10 compress metal clip springs makes fiber alignment accurately and clamps, can anti-vibration;
11 side's lids snap in spring base, and the crust of fixed fiber, inner casing end put into by key, and dust cap is locked on draw-in groove lock pin.
The present invention adopts stainless metal clip spring, substitutes plastic cement gland.Due to the constant voltage of sheet metal, the impact of not expanded with heat and contract with cold.
The present invention adopts V-shaped groove aluminium flake, and its surface anodization improves hardness, thus does not affect Insertion Loss, return loss optical property.
The present invention adopts serial verb construction, the design that the constitutional detail tightening up optical fiber skin cable from draw-in groove lock pin to afterbody solidus groove becomes to be integrated, solves built-in fiber inner bare fibre amount of bow when draw-in groove lock pin pressurized inside contracts and expands 0.7mm to from 0.1mm and cause disconnected fine problem.
FTTH (Fiber To The Home) is that an optical fiber is directly to family.Specifically, FTTH refers to and optical network unit (ONU) is arranged on household user or enterprise customer place, is the optical access network application type near user except FTTD (fiber to the desk) in soft exchange series.
