Description
The application be on May 26th, 2016, application No. is 201610361997.2, entitled " data the applying date
The divisional application of cable ".
Technical field
The present invention relates to field of signal transmissions, and in particular to data cable.
Background technique
With the high speed development of optical communication technique, the backbone network and interoffice trunk of wire net generally use light
Cable, optical fiber enter access net and have become inexorable trend.But fiber cable laying expense is too high, connector expense and terminal optical-electronic exercise fees
With valuableness, therefore, within a very long time before optical fiberization is universal, the user's line for accessing net will be based on metal cables.Number
The transmission media of more satisfactory broadband access network at present according to cable as a kind of metal cables, it have manufacturing cost it is lower,
Structure is simple, expandability is good, is convenient for the advantages of network upgrade, is mainly used for building wiring, cell computer generalization cloth
Line etc..
Existing data cable includes cruciform skeleton and the sheath that is arranged in outside cruciform skeleton, and multiple groups are twisted
Line to being separately positioned in the corresponding mounting groove of skeleton, the data cable of this spline structure when in use, the opposite position of each group line pair
It sets and is easy to channel bit, cross-talk resistant jamming performance is weaker.
Summary of the invention
The present invention is in view of the above-mentioned problems, propose a kind of data cable.Solves the phase of available data cable each group line pair
Position is easy to channel bit, the weaker problem of cross-talk resistant jamming performance.
The technical solution adopted by the present invention is as follows:
A kind of data cable, comprising:
Criss-cross skeleton, for tool there are four mounting groove, each mounting groove includes two orthogonal side walls, is had on side wall
Multiple the first limit raised lines along backbone length direction arrangement, the height of the first limit raised line gradually become along the radial direction of skeleton
Change, and more outward, the height of the first limit raised line is bigger, and each first limit raised line constitutes accommodation space in mounting groove；
Four groups of twisted lines pair, are separately mounted in corresponding accommodation space；
Four pieces of cover plates are covered each by corresponding mounting groove, and cover plate has towards the side of line pair to be protruded into mounting groove
Raised line is limited to the second of cooperation with line；
Waterproof cloth, outsourcing is in the outside of the skeleton and cover plate；
Sheath, outsourcing is in the outside of the waterproof cloth.
The first limit of setting raised line in the two side walls of mounting groove, and the height of each first limit raised line is along the radial direction of skeleton
Direction gradually changes, and setting in this way can prevent movement and deformation, to make between line pair effectively by line to limiting
Distance keeps more uniform stabilization, improves the cross-talk resistant jamming performance of cable；There are two effects for cover plate, first is that can prevent
Water cloth is embedded in mounting groove, influences data cable quality；Second is that the second limit raised line of cover plate can further limit line pair
Position guarantees line to position.
Optionally, the end face of the second limit raised line has arc groove.
Arc groove design so that second limit raised line and line it is big to the area of cooperation, good limit effect.
Optionally, each side wall of the mounting groove all has three first limit raised lines, the first limit raised line
Cross section is trapezoidal or triangle.
Optionally, the mounting groove has a recess adjacent to the end of sheath, the both ends of cover plate by glue with it is corresponding recessed
Mouth is relatively fixed.
Optionally, the cover plate is arc, after cover plate and skeleton cooperate, the lateral wall and skeleton lateral wall of cover plate
It is adapted.
Optionally, the data cable manufacturing method the following steps are included:
1) skeleton and cover plate is made in extrusion molding, and skeleton and cover plate are dried；
2) by line to being installed into the corresponding mounting groove of skeleton, skeleton, line pair and cover plate are carried out by shaping equipment
Sizing；
3) waterproof cloth is wrapped up in the outside of the skeleton after sizing and cover plate；
4) sheath is wrapped up in the outside of waterproof cloth by extrusion moulding apparatus.
Optionally, the shaping equipment in the step 2) includes:
Shaper, has a round limit hole, and the skeleton, line pair and cover plate pass through the round limit hole；
Four groups of rubber-coated mechanisms, for carrying out gluing to the recess；
Four groups of rolling press-wheels cooperate with corresponding cover plate respectively, cover plate are pressed together on to the recess of corresponding mounting groove
On.
The rolling press-wheel closes on the shaper between shaper and rubber-coated mechanism.
Optionally, the criss-cross skeleton includes four points of framves, and the end of point frame is arranged in the recess；The gluing
Mechanism includes:
Gluing frame, positioned at the corresponding outside for dividing frame, gluing frame is connected to by pipeline with glue case；
Two glue brushes, one end and the gluing frame of each glue brush are fixed, and the other end stretches to corresponding recess on point frame；
Pressure pump, for painting the glue in glue case by Pipeline transport to glue.
When work, skeleton and cover plate are mobile, and pressure pump paints the glue in glue case by Pipeline transport to glue, glue brush
With the recess relative motion for dividing frame, while glue is applied on recess.
The beneficial effects of the present invention are: the first limit of setting raised line in the two side walls of mounting groove, and each first limit convex
The height of item is gradually changed along the radial direction of skeleton, and setting in this way can prevent to move effectively by line to limiting
Deformation, thus make line to the distance between keep more uniform stabilization, improve the cross-talk resistant jamming performance of cable；Cover plate has two
A effect influences data cable quality first is that waterproof cloth can be prevented to be embedded in mounting groove；Second is that the second limit raised line of cover plate
The position of line pair can be further limited, guarantees line to position.
