Description
Technical field
The utility model is about a kind of transmission cable, refers to a kind of twisted pair wire cable especially.
Technical background
Anaiog signal and the modal transmission medium of numerical digit signal are twisted pair wire cable (twisted paircable are hereinafter to be referred as the strand cable), and it is the basis of telephone wire transmission system, also is the main transmission medium of present computer local-area network (LAN).
As shown in Figures 1 and 2, a common strand cable 30 is by many twisted pair wire 31 harnesses (a common existing strand cable has four pairs of twisted pair wires) together, beyond wrap the outside again by 32 protections.One twisted pair wire 31 comprises that two are reversed into spiral helicine insulated conductor 33, and each insulated conductor 33 comprises a bare wire 34, and an insulating barrier 35 that is coated on this bare wire 34.
Existing strand cable 30, owing to just all twisted pair wires 31 are bundled together, therefore, twisted pair wire 31 is not to be in stable state, makes twisted pair wire 31 be easy to be subjected to electrical Interference.
In order to reduce the electrical Interference between the twisted pair wire, so the dealer further develops out the strand cable that can make twisted pair wire stable, as shown in Figure 3, the manufacturing process of this strand cable 40 is as follows:
One, utilizes coating extrustion process (extrusion coating) that two bare wires 41 are extruded in nib in company with insulating barrier 42, form insulated conductor 43, and two insulated conductors 43 are reversed into helical form when waiting to harden, become twisted pair wire 44.
Two, the filler 45 of moulding cross section.
Three, each twisted pair wire 44 is placed a grid 46 of filler 45 respectively after, filler 45 and twisted pair wire 44 are imposed twisting action (be commonly referred to as total strand, purpose is stabilized twisted pair wire), again in company with being extruded in nib by 47 outward, and be coated on twisted pair wire 44, form strand cable 40.
Though above-mentioned strand cable 40 can make each twisted pair wire 44 be fixed on the location, but because of after this filler 45 is indivedual moulding, extruded in nib by 47 outward with twisted pair wire 44 companions, because number of components is more, need total strand operation again, manufacturing process is comparatively loaded down with trivial details, and the strand cable can't be made under most economical situation very efficiently.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above and the shortcoming of prior art, and a kind of twisted pair wire cable of improvement is provided, and this strand cable can make each twisted pair wire be fixed on and define the position, can reduce the electrical Interference between the twisted pair wire.
Another purpose of the present utility model is to provide a kind of strand cable, and this strand cable can omit the operation of total strand and simplify processing procedure, enhances productivity, and reduces manufacturing cost, additional income.
The purpose of this utility model is achieved in that
A kind of twisted pair wire cable includes plural twisted pair wire, and each twisted pair wire has two and is reversed into spiral helicine insulated conductor along length direction; It is characterized in that also including:
One outer quilt comprises one and is coated on the pipe portion of twisted pair wire, and has the plural rib that is formed in this pipe portion, and these ribs and pipe portion define plural receiving room, this each receiving room receivability one twisted pair wire.And
This receiving room number is identical with the twisted pair wire number.
Good effect of the present utility model is: because the utility model comprises a plural twisted pair wire and an outer quilt, particularly should be outer be had a pipe portion that is coated on twisted pair wire, and has a plural rib that is formed in this pipe portion, these ribs and pipe portion define plural receiving room, each receiving room receivability one twisted pair wire can separate each other twisted pair wire and is fixed on and defines the position, to reduce the electrical Interference between the twisted pair wire, can omit simultaneously total strand operation, improve the production efficiency of twisted pair wire cable.

Embodiment
The utility model reaches the technology contents of above-mentioned purpose and other characteristics can be clear fully with reference to the graphic preferred embodiment explanation of following cooperation.
As shown in Figs. 4-6, specific implementation " twisted pair wire cable " the 10th of the present utility model, by being formed by 2 outside plural twisted pair wire 1 and one, in the embodiment of accompanying drawing, the number of twisted pair wire 1 has four pairs; Certainly, the embodiment of accompanying drawing is intended to illustration and explanation, and is not intended to be limited to any specific number, and with regard to the number of other twisted pair wires, the arrangement of for example six pairs, eight pairs or ten equities is from also being included in spirit of the present utility model and the scope.Described each twisted pair wire 1 has two bare wires 11, and utilize coating extrustion process (extrusioncoating), and be coated on the insulating barrier 12 of each bare wire 11, form insulated conductor 13, and when sclerosis of waiting two insulated conductors 13 are reversed into helical form, become twisted pair wire shown in Figure 61.
Describedly outer comprised a pipe portion 21 that is coated on twisted pair wire 1 by 2, and has a plural rib 22 that is formed in this pipe portion 21, these ribs 22 define and twisted pair wire 1 the same number of receiving room 23 altogether with pipe portion 21, each receiving room 23 receivabilities one twisted pair wire 1, make twisted pair wire 1 can be spaced from each other and be fixed on the location, to reduce the electrical Interference between the twisted pair wire 1.
Because each twisted pair wire 1 is after being positioned in a receiving room 23, promptly present highly stable state, so lining outer by 2 before, need not the traditional cable that twists of picture, all twisted pair wires are imposed twisting action, it is bundled together makes it stable, thereby can omit total strand operation, and simplify the processing procedure of strand cable, enhance productivity, reduce manufacturing cost, increase profit.
Described also is to utilize the coating extrustion process to form by 2 outward.When extruding, make all twisted pair wires 1 outward in company with being extruded in nib by 2.
Need know, being required to be the plastic material that can not fuse mutually by 2 with the insulating barrier 11 of twisted pair wire 1 outward extrudes and forms, for example insulating barrier 11 is polyethylene (PE) or polypropylene (PP), be can be polyvinyl chloride (PVC) by 2 then, extruded Shi Buhui with insulating barrier 12 bondings by 2 outside making, to form crosslinked polythene insulation PVC lining strand cable.
Moreover the utility model is not restricted to the described embodiments, for example, outward by 2 pipe portion 21 except circle, also can be rectangle (Fig. 7), square (Fig. 8 and Fig. 9); As for the shape of the visual pipe of rib 22 portion 21, crisscross (Fig. 4 and Fig. 8), X-shaped (Fig. 9) or be arranged in parallel (Fig. 7).Certainly, the embodiment of accompanying drawing is intended to illustration and explanation, and is not intended to be limited to any specific shape, and with regard to other suitable shapes, for example design of ellipse etc. is from also being included in spirit of the present utility model and the scope.
