Description

A kind of three rings, three feeder line jigs
Technical field
The present invention relates to communication equipment field, particularly a kind of three rings, three feeder line jigs.
Background technique
In communications industry; The equipment that is used for fixing synchronously cable that comes out from the base station and optical cable is on the feeder line card; General feeder line card structure comprises at present: screw rod, feeder line fastener, C type card frame, and the feeder line fastener passes screw rod and fixes through the nut and the screw rod at two ends, and screw rod passes C type card frame one end and fixes.During use, C type card frame is fixed on the fixation means such as iron tower, and the feeder line fastener is used for fixing cable and optical cable.Wherein the feeder line fastener is moulded the card unit by at least one and a sonet card unit is formed, and common is called two, mould card unit and sonet card unit by about two fasten each other mould card and sonet card is formed, respectively form two manholes behind the fastening, be commonly called as two rings.Mould the card unit and be used for fixing cable, fiber unit is used for fixing optical cable.
Because the specification of cable is a lot, the specification of optical cable also has quite a few kinds.Collocation is got up having tens kinds of feeder units like this, and prevailing three dicyclo feeder line cards can not satisfy the feeder line requirement of fixing so many specifications fully at present, and can not arbitrarily add feeder unit again for the national examination criteria of process on the feeder line card.So, fasten with regard to the feeder line that needs plurality of specifications during cabling in multiple not collinear footpath, the cost when so installing will increase, and waste man-hour.
Summary of the invention
The technical problem that the present invention will solve provides a kind of three or three ring feeder line cards of fixing multiple cable.
For solving the problems of the technologies described above; Technological scheme of the present invention is: a kind of three rings, three feeder line jigs comprise: C type card frame, screw rod, feeder line fastener, and said feeder line fastener passes screw rod and fixes through the nut and the screw rod at two ends; Said screw rod passes C type card frame one end and fixes; Its innovative point is: said feeder line fastener moulds the card unit by one and two sonet card unit are formed, and moulds the card unit and is made up of two cards of moulding that fasten each other, and the sonet card unit is made up of two optical fiber cards that fasten each other; The said side, card unit of moulding has three hollow cylinder die cavities, and the one-sided bin of said sonet card has three hollow ellipse cylinder die cavities; Said three hollow cylinder die cavities all are embedded with reduction center; Said on the screw rod of feeder line fastener two ends, being with moulded card compressing tablet and sonet card compressing tablet and fixed through nut.
Further, be provided with several bar shaped decorative patterns on said hollow cylinder die cavity and the hollow ellipse cylinder-type cavity wall.
Further, said reduction center is a semi-hollow cylindrical body die cavity face, and said reduction center is provided with projection and has the through hole that cooperates with projection on the circular arc top.
Further, the material of said reduction center is a polyethylene.
Further, the elliptical aperture aperture on the said sonet card is: 5mm-7mm.
Further, the described card compressing tablet of moulding is the cuboid thin slice that two ends are upturned, and the said card compressing tablet surface of moulding has and can hold the through hole that screw rod passes.
Further, the said card compressing tablet surface of moulding is provided with some the stiffening ribs that are distributed in around the through hole.
Further, said sonet card compressing tablet is and the cuboid thin slice of moulding the profiling of card compressing tablet.
The invention has the advantages that: feeder line fastener of the present invention is moulded the card unit by two sonet card unit and one and is formed, and just three, the through hole of three similar sized apertures is arranged, just three rings on each unit.Wherein especially the hole on the sonet card unit is an elliptical aperture, and the aperture is 5mm-7mm, and the hole is embedded with the reduction center of different size at the most on the card unit moulding, and has increased the specification of fixed cable, avoids installing the feeder line card of plurality of specifications, has practiced thrift installation cost.On the screw rod of feeder line fastener two ends, be with and mould card compressing tablet sonet card compressing tablet and fix through nut, make the two ends clamping force increase, each unit fits tightly in the feeder line fastener, helps the stable of fixed cable transmission.
