Abstract
The utility model relates to a grinding clamp for an optical fiber connector with a high return loss. The grinding clamp is provided with an orthohexagnal grinding plate, wherein a radial convex positioning boss is designed at a joint of edges of the grinding plate; four parallel clamping holes are drilled on the grinding plate close to each edge; radial threaded holes corresponding to the clamping holes are formed on six side walls of the grinding plate; each of the threaded holes is provided with a fastening bolt; the grinding clamp is characterized in that the four clamping holes formed side by side are all inclined clamping holes with inward inclined upper openings; a limiting boss is designed outside each row of clamping holes; a straight edge is arranged inside the limiting boss; the straight edge is parallel to a central line of the four clamping holes; and the straight edge of the limiting boss is pitched in small parts at the upper openings of the four clamping holes. The grinding clamp provided by the utility model is used for solving the problem that the traditional grinding clamp for the optical fiber connector cannot be used for grinding a nonstandard head with an inclined angle, the direction of the nonstandard head can be accurately confirmed, the clamping efficiency is greatly increased and the grinding clamp is mainly used for grinding the nonstandard head of the optical fiber connector with the inclined angle.
Description
The (1) technical field: the utility model relates to the manufacturing field of fiber products, especially a kind of high return loss joints of optical fibre grinding clamp.
(2) background technology: in the processing of the joints of optical fibre, will the non-header of connector be ground at last, to improve the return loss of the joints of optical fibre; Strengthen its optical property; Existing joints of optical fibre grinding clamp, its folder hole are that vertical hole shape can not adapt to the non-header grinding with angle of inclination, and can not locate; Grinding precision is not high enough, and quality is good inadequately.
The (3) summary of the invention: the purpose of the utility model is exactly will solve existing fiber connector grinding clamp can not grind the non-header with angle of inclination; Can not locate; Grinding precision is not high enough, and the imperfect problem of quality provides a kind of high return loss joints of optical fibre grinding clamp.
The concrete scheme of the utility model is: improve to existing grinding clamp; It has the regular hexagon abrasive sheet; Junction grinding edges of boards and limit is designed with the radially positioning table of evagination; And on abrasive sheet, be drilled with four folder holes that are arranged side by side near each limit, amount to 24 folder holes, corresponding each folder hole is shaped on a radial screw bore on six sides of abrasive sheet; Each screwed hole is furnished with a trip bolt, it is characterized in that: four folder holes of said every row are the oblique folder hole that tilts to the inside suitable for reading; And the outside in each row folding hole is designed with positive stop lug boss, and this positive stop lug boss inboard is a straight line, and this straight line is parallel with the line of centres of four folder holes, and the fraction suitable for reading of four folder holes of the straight line of boss incision.
Axis according to two kinds of said folder holes of nonstandard head tilt angle design of present the best becomes 8.8 ° or 11.7 ° of angles with vertical line.
1 ± the 0.2mm suitable for reading of four folder holes of straight line incision of positive stop lug boss described in the utility model.
The utility model in use; Because cutting has locating surface on the non-header of the joints of optical fibre; When grinding clamped, the straight line of the positive stop lug boss in its locating surface and the utility model matched and forms the corner location, the folder hole that is in tilted layout simultaneously can be fit to the to tilt clamping grinding of non-header.The utility model is simple in structure, and is easy to operate, and the location is reliable quick, and grinding precision is high, and quality is good, can greatly reduce the return loss of the joints of optical fibre.
The (4) description of drawings:
Fig. 1 is the front view of the utility model;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the B-B view of Fig. 1.
Among the figure: 1-abrasive sheet, 2-positioning table, 3-folder hole, 4-screwed hole, 5-positive stop lug boss, 6-trip bolt.
The (5) specific embodiment:
Referring to Fig. 1,2,3; The utlity model has regular hexagon abrasive sheet 1; Be designed with the positioning table 2 of warp-wise evagination in the junction on abrasive sheet 1 limit and limit; And on abrasive sheet 1, be drilled with four folder holes that are arranged side by side 3 near each limit, amount to 24 folder holes 3, corresponding each folder hole 3 is shaped on a radial screw bore 4 on six sides of abrasive sheet 1; Each screwed hole 4 is furnished with a trip bolt 6, and particularly: four folder holes 3 of said every row are the oblique folder hole 3 that tilts to the inside suitable for reading; And be designed with positive stop lug boss 5 in the outside in each row folding hole 3, these positive stop lug boss 5 inboards are straight line, and this straight line is parallel with the line of centres of four folder holes 3, and the fraction suitable for reading of four folder holes 3 of the straight line of boss incision.The axis of folder hole described in the present embodiment 3 becomes 8.8 ° with vertical line, (or be designed to 11.7 ° of angles, and can also confirm angle according to newly-designed nonstandard head tilt angle), the 1 ± 0.2mm suitable for reading of four folder holes 3 of straight line incision of said positive stop lug boss 5.Promptly constitute the utility model.
Claims (3)
1. one kind high return loss joints of optical fibre grinding clamp; Has the regular hexagon abrasive sheet; Junction grinding edges of boards and limit is designed with the radially positioning table of evagination; And on abrasive sheet, be drilled with four folder holes that are arranged side by side near each limit, amount to 24 folder holes, corresponding each folder hole is shaped on a radial screw bore on six sides of abrasive sheet; Each screwed hole is furnished with a trip bolt, it is characterized in that: four folder holes of said every row are the oblique folder hole that tilts to the inside suitable for reading; And the outside in each row folding hole is designed with positive stop lug boss, and this positive stop lug boss inboard is a straight line, and this straight line is parallel with the line of centres of four folder holes, and the fraction suitable for reading of four folder holes of the straight line of boss incision.
