Abstract
The utility model relates to a low interference network cable having shielding intervals, which comprises a cable core having a plurality of pairs of twisted pair cables (1) and an outer sheath (2) covered outside the cable core; the utility model is characterized in that: the cable core also includes a shielding separating shelf (3), which uniformly divides the cable core in a circumferential direction into shielding compartments (4) having the same pairs with the twisted pair cables (1), and the pairs of twisted pair cables (1) are respectively arranged inside the shielding compartments (4). The utility model resolves the problem of interference between prior network cable pairs, thereby improving the electric transmission characteristics and increasing the network bandwidth and signal velocity so as to contribute better excellent physical transmission medias for china to establish an advanced and developed information-based society.
Description
Technical field
The utility model relates to a kind of network cable, is specifically related to a kind of low network cable of crosstalking of tool shielding compartment.
Background technology
Along with the continuous development of information communication, users increase fast to the demand of information, such as the multimedia communication that utilizes computer, video telephone and video conferencing etc.At present, the user realizes that the network cable of broadband access generally uses the copper cable twisted-pair cable.
Existing copper cable twisted-pair cable comprises by many pair twist electric wire constituted cable core, cable core be covered successively more outward screen and oversheath.Though the inner twisted pair wire form that adopted of its copper cable is resisted extraneous electromagnetic interference, still since each line between apart from very near, line makes the improvement of signal bandwidth and speed be subjected to limitation to having crosstalk phenomenon.
Summary of the invention
The purpose of this utility model is to solve the line that exists in the prior art to there being the technical problem of crosstalk phenomenon, and a kind of low network cable of crosstalking of tool shielding compartment is provided.
For achieving the above object, the technical solution adopted in the utility model is: the low network cable of crosstalking of a kind of tool shielding compartment, comprise have many to the pair twist electric wire cable core and be coated on the outer oversheath of cable core; Wherein, also comprise a shielding isolating frame in the described cable core, this shielding isolating frame is at all shielding compartments that upwards evenly is separated out with pair twist electric wire logarithm equal amount of cable core, and each is respectively in respectively the pair twist electric wire and shields in the compartment.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described shielding isolating frame is meant the separation shape support body of tool shielding properties, and preferable employing semiconductive material is as the semiconductive plastics.Preferred version is: have four pairs of pair twist electric wires in the described cable core, the shielding isolating frame then corresponds to the semiconductive plastic processing frame of star section.
The utility model design principle and the effect of bringing are: the utility model is separated each in shielding compartment separately to the pair twist electric wire by the shielding isolating frame, location and guaranteed that each line is at a distance of certain distance, shielding intercepted each line between signal influence each other, fundamentally overcome line between crosstalk phenomenon take place, improved the electrical communications characteristic, signal bandwidth and speed are further enhanced.
Description of drawings
Accompanying drawing 1 is the utility model embodiment one structural representation;
Accompanying drawing 2 is the utility model embodiment two structural representations.
In the above accompanying drawing: 1, pair twist electric wire; 2, oversheath; 3, shielding isolating frame; 4, shielding compartment; 5, conductor wire core; 6, insulating barrier; 7, metal forming screen; 8, woven shield.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: shown in accompanying drawing 1, a kind of low network cable of crosstalking of tool shielding compartment comprises the cable core of four pairs of pair twist electric wires 1, and from inside to outside is coated on cable core outer metal forming screen 7, woven shield 8 and oversheath 2 successively; Also comprise a shielding isolating frame 3 in the described cable core, this shielding isolating frame 3 is the semiconductive plastic processing frame of star section, and the semiconductive plastic processing frame upwards evenly is being separated out four shielding compartments 4 cable core week, and each is respectively in pair twist electric wire 1 and respectively shields in the compartment 4.Each pair twist electric wire 1 constitutes by conductor wire core 5 outsourcing insulations 6.
Present embodiment is the low network cable of crosstalking of tool external shield, and its line is all very excellent to a shield effectiveness and exterior shield effect, no crosstalk phenomenon.
Embodiment two: shown in accompanying drawing 2, the low network cable of crosstalking of a kind of tool shielding compartment comprises the cable core of four pairs of pair twist electric wires 1, is with the difference of embodiment one: only coat oversheath 2, not provided with shielding layer outside cable core.Other repeat no more here with embodiment one.
The present embodiment line is good to a shield effectiveness, no crosstalk phenomenon.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection range of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the present utility model.
Claims (2)
1, the low network cable of crosstalking of a kind of tool shielding compartment, comprise have many to pair twist electric wire (1) cable core and be coated on the outer oversheath (2) of cable core; It is characterized in that: also comprise a shielding isolating frame (3) in the described cable core, this shielding isolating frame (3) is at the shielding compartment (4) that upwards evenly is separated out in cable core week with pair twist electric wire (1) logarithm equal amount, and each is respectively in pair twist electric wire (1) and respectively shields in the compartment (4).
2, shield the low network cable of crosstalking of compartment according to the tool of claim 1, it is characterized in that: have four pairs of pair twist electric wires (1) in the described cable core, shielding isolating frame (3) then corresponds to the semiconductive plastic processing frame of star section.
