Abstract
The invention discloses a flat subscriber line, which comprises conductors, insulating layers coated outside the conductors, and a sheath for coating a plurality of conductors arranged side by side and the insulating layers thereof, wherein the sheath comprises an inner sheath and an outer sheath, the inner sheath is filled around each insulating layer, the transverse section of the inner sheath is in a dumbbell shape, the thickness of arc surfaces at two sides is slightly larger than the middle plane, the outer sheath is coated outside the inner sheath, and the thickness of the arc surfaces at two ends is also slightly larger than the middle plane. The invention has beautiful appearance, good consistency, difficult damping and aging, good mechanical property and long service life, and can be widely applied in the field of communication transmission terminals. The system has low overall cost and convenient use, and provides a brand-new solution for each operator.
Description
Technical field
The present invention relates to a kind of flat user wire.
Background technology
Along with the arrival of cybertimes, the popularizing of computer is widely used in order to the flat cable of transmission signals; flat conductor thickness is little; be easy to lay, it generally includes lead and is arranged on the outer insulation protection glued membrane of lead, and lead is arranged in parallel within the insulation protection glued membrane.When but such flat cable was subjected to bigger pressure in laying use, insulator might break and cause plain conductor to expose even two leads contact back short circuits, makes communication normally to carry out.Therefore, in order to guarantee the intensity of lead, the design of pressure buffer body occurred connecting at two sides of flat conductor, but such structure makes the integral width of cable broaden, radius of curvature is too big when the needs bending is laid, and should not operate.
Summary of the invention
The object of the invention provides a kind of flat user wire, and its duplex sheath design makes it have very high mechanical strength, can prevent the moisture invasion again, and shield electromagnetic interference is also played a role, and when optimizing the lead performance, has also increased its useful life.
Technical scheme of the present invention is: a kind of flat user wire, comprise conductor, the outer insulating barrier that coats of conductor, and a plurality of conductors that are arranged side by side and insulating barrier thereof wrapped up sheath in it, described sheath comprises inner sheath and oversheath, inner sheath be in each insulating barrier around, its lateral cross section becomes dumbbell shaped, both sides arc surface thickness is slightly larger than mid-plane, and oversheath is coated on outside the inner sheath, and its two terminal circle cambered surface thickness also is slightly larger than mid-plane.
The further technical scheme of the present invention is: a kind of flat user wire, comprise conductor, the outer insulating barrier that coats of conductor, and a plurality of conductors that are arranged side by side and insulating barrier thereof wrapped up sheath in it, described sheath comprises inner sheath and oversheath, inner sheath be in each insulating barrier around, its lateral cross section becomes dumbbell shaped, both sides arc surface thickness is slightly larger than mid-plane, and oversheath is coated on outside the inner sheath, and its two terminal circle cambered surface thickness also is slightly larger than mid-plane; Described inner sheath is the PE material, and oversheath is the PVC material, and inside and outside sheath inboard respectively is provided with one and tears rope.
Advantage of the present invention is:
1. the present invention adopts duplex sheath, makes it have very high mechanical strength, can prevent the moisture invasion again, and shield electromagnetic interference is also played a role, and when optimizing the lead performance, has also increased its useful life.
2. oversheath of the present invention adopts the PVC material, has good flame-retarding characteristic, and is convenient and safe when the user uses.
3. insulating barrier of the present invention combines with conductor firmly, when variations in temperature or when stretching, and not combining and can relatively move between insulating barrier and the inner wire.
4. sheath of the present invention is down vertical has put the rope of tearing that a rhizopodium is enough opened cable cover(ing), and line meets the Meng Saier colour code to color clear, and these characteristics bring great convenience to construction.
5. flat structure of the present invention is easy to lay, and is elegant in appearance, both can hang on the wall, also can be laid within the walls.
6. material therefor of the present invention all adopts ep-type material, and environment and human body are not had injury, and this is also just meeting the aim of the construction environment-friendly type society that advocates in the current whole world.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein: 1 conductor; 2 insulating barriers; 3 sheaths; 31 inner sheaths; 32 oversheaths; 4 tear rope.
Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
Embodiment: as shown in Figure 1, a kind of flat user wire comprises conductor 1, and it is a TR type annealed copper wire; The conductor 1 outer insulating barrier 2 that coats, it is the PE material; And with a plurality of conductors that are arranged side by side 1 and its interior sheath 3 of insulating barrier 2 parcels thereof.Described sheath 3 comprises inner sheath 31 and oversheath 32, described inner sheath 31 is the PE material, oversheath 32 is the PVC material, inner sheath 31 contacts with insulating barrier 2, is full of around each insulating barrier 2, to the effect of insulating barrier 2 and conductor inside 1 restricted position and reinforcing, its lateral cross section becomes dumbbell shaped, both sides arc surface thickness is slightly larger than mid-plane, and oversheath 32 is coated on outside the inner sheath 31, and its two terminal circle cambered surface thickness also is slightly larger than mid-plane.Like this, when being under pressure, the thick slightly circular arc in both sides can be shared most of pressure, and the part thin to the centre has protective effect.Inside and outside sheath 31,32 inboards respectively are provided with one and tear rope 4, can open sheath very easily when construction, and conductor 1 and insulating barrier 2 are exposed operation.
The present invention adopts unique design, and is specious, high conformity, moisture-sensitive, aging not, good mechanical property, long service life.
Claims (2)
1. flat user wire, comprise conductor (1), the outer insulating barrier (2) that coats of conductor (1), and a plurality of conductors that are arranged side by side (1) and insulating barrier (2) thereof be wrapped in sheath (3) in it, it is characterized in that: described sheath (3) comprises inner sheath (31) and oversheath (32), inner sheath (31) be in each insulating barrier (2) around, its lateral cross section becomes dumbbell shaped, both sides arc surface thickness is slightly larger than mid-plane, oversheath (32) is coated on outside the inner sheath (31), and its two terminal circle cambered surface thickness also is slightly larger than mid-plane.
