Description
[technical field]
The utility model relates to a kind of extruded mould that is used for network digital cable twisted-pair feeder.
[background technology]
At present, be applied to the twisted-pair feeder of network digital cable, be to coat production respectively by the two eradication edge conductive core lines that adopt the single hole extruded mould will form twisted-pair feeder, extrude one at every turn and thoroughly do away with the edge conductive core line, two of twice extrusion molding production thoroughly does away with the edge conductive core line again by the stranded twisted-pair feeder that becomes of other equipment, finishes the manufacturing of elementary cell.
This extruded mould includes head, and core rod and die cap only are provided with the passage that passes through for an eradication edge conductive core line in the core rod, and it adopts the concentric extrusion molding structure of single hole, can only coat single insulation conductive core line to produce.Reason owing to tension force, the centre-to-centre spacing of two insulated electric conductor heart yearns can change in stranded process, the probability that changes the scope that exceeds requirement is very big, on change point, can produce the reflection of signal, the amplitude of the reflected signal of pip, can produce the stack of amplitude under some particular environment, serious meeting infringement transmission quality causes the defective of transmission performance indicators.This is during conventional art is produced, the most scabrous problem.
On the other hand; this single hole extruded mould is in extruding the process of heart yearn; because the variation on the machine driven system; the fluctuation of supply voltage, the factors such as variation of environment temperature; the capital brings the external diameter of insulating protective layer to change; cause the variation of the concentricity at insulating barrier center and conductor core wire center, the single coating production of twisted-pair feeder causes the underproof probability of electrical property of twisted pair energy index bigger.
[summary of the invention]
The purpose of this utility model provides a kind of simple in structure, and result of use is good, and once the while extrusion molding goes out two different colour codes and the extruded mould of the parallel insulation heart yearn of the one that bonds.
The purpose of this utility model is achieved in that
A kind of extruded mould that is used for network digital cable twisted-pair feeder includes the extrusion head body, and the core rod seat is provided with through hole at the middle part of described handpiece body, and the front end of described core rod seat is arranged in the through hole, and leaves the gap with the handpiece body inwall; Being provided with charging aperture at the sidewall of handpiece body communicates with the gap, it is characterized in that being fixed with core rod in the described core rod seat, be provided with in the described core rod and can be provided with die cap in the through hole exit position of handpiece body, and be provided with the outlet diplopore by the outlet passage of two conductive core lines at die cap upper edge outlet passage.
Aforesaid a kind of extruded mould that is used for network digital cable twisted-pair feeder, the outlet diplopore sidewall that it is characterized in that described die cap are provided with the passage of the conductive core line dyeing that will pass through, and described passage communicates with charging hole on the handpiece body.
Aforesaid a kind of extruded mould that is used for network digital cable twisted-pair feeder, the outlet diplopore that it is characterized in that described die cap is the ∞ font.
Aforesaid a kind of extruded mould that is used for network digital cable twisted-pair feeder is characterized in that being fixed with adpting flange in the entry position of charging aperture.
The beneficial effects of the utility model are: 1, extruded mould can once be finished the parallel insulation heart yearn of two different colour codes and bonding one simultaneously, can greatly improve the transmission characteristic of cable, and improve the stability of construction of cable performance greatly.2, just the distance between two of the twisted-pair feeder eradication conductive core lines and the centre-to-centre spacing of conductor all remain constant on the each point of drum length of cable, the influence to the product electric property of the concentricity, out-of-roundness of conductor insulation has been got rid of in tight variation little when in time big during pine when the centre-to-centre spacing of distance between the conductive core line of can not insulating and conductor occurs.Thereby solved the inhomogeneities that characteristic impedance changes, made transmission go up the even pip of inequality signal and reduce greatly, improved the transmission performance of network.3, the quality and the production efficiency of network digital cable twisted-pair feeder have been improved greatly.
