Further, the width of described press strip is less than the width of described point fine groove, makes the press strip better fixing optical fiber divided in fine groove.The length of described side plate is equal to or less than the fine pickup groove of input and exports the spacing of fine pickup groove, outside described two side plates, spacing equals box body width, described box body side and side plane contact position be provided with the groove holding side plate, so that demolition packaged fiber shunt.
Further, the inner side of described lid side panels is provided with card article, and the side of described box body is provided with the draw-in groove coordinated with card article, makes box body and lid reliable connection by this simple snap-in structure.
Further, described point of fine groove comprises inlet wire and divides fine groove to divide fine groove with two outlets dividing fine groove to be connected with inlet wire, inlet wire divides fine groove and outlet to divide fine groove in " people " font, described inlet wire divides fine groove to be communicated with the fine pickup groove of input, described outlet divides fine groove to be communicated with the fine pickup groove of output, ensures that optical fiber occurs bending or is wound around in point fine groove further.
Further, fiber optic protection layer is provided with in described point of fine groove, optional froth bed or rubber layer; optical fiber splitter generally adopts rigid plastic to make; directly optical fiber is snapped in during installation in point fine groove of plastics, easily damage optical fiber, the fiber optic protection layer energy available protecting optical fiber in point fine groove.
The beneficial effects of the utility model:
The utility model provides a kind of tension optical fiber splitter, by being arranged on the optic fibre fixing device that box body two ends input fine pickup groove and export fine pickup groove sidewall, strengthen the tensile strength of optical fiber splitter, lid again by being connected with Snap of box, make optical fiber splitter have good sealing, thus play optical fiber protection against the tide, dust-proof effect.
