[0002] With the rapid development of the communications and power industries, higher and higher performance requirements are placed on cables, especially on the waterproof performance of cables. First, the outer sheath of the cable is prone to aging and cracking during use, and external water vapor will enter the cable from the cracks, affecting the electrical performance of the cable. Secondly, when the core wire of the axial connection end of the cable is connected to the connector, the core wire of the connection end needs to be wrapped with insulating tape to achieve a waterproof effect. However, the insulating tape is prone to loosening after long-term use, resulting in poor waterproofing effect. Water vapor diffuses from the axial connection end of the cable to the inside of the cable, affecting the electrical performance of the cable. Utility Model Content

[0006] Furthermore, in the aforementioned high-resistance water-resistant Category 6 communication cable, the cross frame is made of PE material, and the support arm and the T-shaped stop end are integrally formed.

[0007] Furthermore, in the aforementioned high water-resistance Category 6 communication cable, the wrapping direction of the non-woven fabric tape is opposite to the wrapping direction of the aluminum-plastic composite tape.

[0009] Furthermore, in the aforementioned high water-resistance Category 6 communication cable, the overlapping position of the water-blocking tape and the overlapping position of the coated non-woven fabric are arranged opposite to each other.

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a structural schematic diagram of the high water-resistance Category 6 communication cable described in the utility model. DETAILED DESCRIPTION

[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0017] like Figure 1As shown, the high-resistance water-resistant category 6 communication cable described in the utility model includes: a cross frame 1, the cross frame 1 is made of PE material, the cross frame 1 made of PE material has a lower dielectric constant, and can better play the role of isolating signals, a chamber is formed between each two adjacent support arms 11 of the cross frame 1, and a T-shaped stopper 12 is arranged on each support arm 11 of the cross frame 1, the support arm 11 and the T-shaped stopper 12 are integrally formed, and the T-shaped stopper 12 and the support arm 11 are connected by a smooth arc transition to reduce the local stress between the T-shaped stopper 12 and the support arm 11, and a long blind hole 121 is opened inwardly on the outer side wall of the T-shaped stopper 12, and the long blind hole 121 extends inwardly to be aligned with the smooth arc, and the cross frame 1 Water-blocking powder 13 is adhered to the outer wall and the inner wall of the long blind hole 121. During the production process, the extruded cross skeleton 1 is first passed through the adhesive, and then the cross skeleton 1 coated with adhesive is passed through the powder box containing water-blocking powder 13. The water-blocking powder 13 is spread all over the cross skeleton 1 and the long blind hole 121. A water-absorbing and swellable water-blocking yarn 14 and a twisted pair of wires 2 are arranged in each chamber. Each twisted pair of wires 2 is stuck in the two T-shaped stop ends 12 of the corresponding chamber. When the subsequent wrapping work is carried out, the twisted pair of wires 2 is not easy to detach from the cross skeleton 1, which facilitates the subsequent wrapping work. The pitches of the four twisted pairs of wires 2 are different, which reduces the signal interference between the twisted pairs of wires 2 and improves the transmission performance of the cable. Non-woven fabric tapes 3 are wrapped around the four twisted pairs of wires 2. The woven fabric tape 3 does not contact the cross skeleton 1, which can improve the tightening strength of the non-woven fabric tape 3 on the four twisted wires 2. After being tightened by the non-woven fabric tape 3, the twisted wires 2 will rest on the water-absorbing and swelling water-blocking yarn 14. The water-absorbing and swelling water-blocking yarn 14 plays a buffering role on the twisted wires 2 to prevent the twisted wires 2 from being deformed after being tied too tightly. An aluminum-plastic composite tape 4 is wrapped around the non-woven fabric tape 3, and the wrapping rotation direction of the non-woven fabric tape 3 is opposite to that of the aluminum-plastic composite tape 4, which can enhance the tensile and compressive strength of the cable, make the cable more stable when subjected to external force, and also improve the tightness between the aluminum-plastic composite tape 4 and the non-woven fabric tape 3. The overlap rate of the non-woven fabric tape 3 is between 10% and 15%, which can simultaneously ensure the wrapping stability and softness of the non-woven fabric tape 3, and the aluminum-plastic composite tape 4 is more stable. The shielding rate of the composite tape 4 is between 20% and 25%, which can prevent the shielding effect from being affected by too low a shielding rate, and can also prevent the bending performance of the cable from being affected by too high a shielding rate. A tinned copper wire braided tape 5 is woven on the aluminum-plastic composite tape 4, and the braiding density of the tinned copper wire braided tape 5 is greater than 95%. A coated non-woven fabric 6 is wrapped on the tinned copper wire braided tape 5, and a water-blocking tape 7 is wrapped on the coated non-woven fabric 6. The overlapping position of the water-blocking tape 7 is opposite to the overlapping position of the coated non-woven fabric 6. The coated non-woven fabric 6 is composited by a PE film layer and a non-woven fabric layer. The PE film layer in the coated non-woven fabric 6 is in contact with the tinned copper wire braided tape 5, and the non-woven fabric layer in the coated non-woven fabric 6 is in contact with the water-blocking tape 7. A sheath 8 is extruded on the water-blocking tape 7, and a tear rope 81 is arranged in the sheath 8.

[0018] If there is a crack on the sheath 8, the external water vapor will contact the water-blocking tape 7 after passing through the crack, and the water-blocking tape 7 will swell after encountering water to form a gel-like substance to seal the crack, effectively preventing water vapor from penetrating into the interior of the cable and affecting the electrical performance of the cable. If water penetrates into the interior of the cable from the overlap of the water-blocking tape 7, the non-woven fabric layer in the coated non-woven fabric 6 can absorb the water vapor, and the PE film layer in the coated non-woven fabric 6 can isolate the water vapor adsorbed on the non-woven fabric layer to prevent the water vapor from contacting the tinned copper wire braided tape 5; if the insulating tape on the axial connecting end is loose and encounters water, the water-blocking powder 13 on the cross skeleton 1 and the water-absorbing and swellable water-blocking yarn 14 absorb water and swell to form a gel-like substance to seal the gap at the connecting end and the twisted wire 2. Since the cross skeleton 1 is not in contact with the non-woven fabric tape 3, and the water-blocking powder 13 in the long blind hole 121 will also swell after absorbing water, the long blind hole 121 The expanded water-blocking powder 13 will stretch the T-shaped stopper end 12. After the two T-shaped stopper ends 12 are stretched, the twisted wires 2 in the chamber will be clamped. In this way, the sealing effect of the expanded water-blocking powder 13 on the T-shaped stopper end 12 on the twisted wires 2 can be improved, and water vapor can be more effectively prevented from diffusing into the twisted wires 2. After absorbing water, the water-blocking tape 7 will expand toward the coated non-woven fabric 6, the tinned copper wire braided tape 5 and the aluminum-plastic composite tape 4 to form a gel-like substance, thereby forming a good water-blocking layer on the tinned copper wire braided tape 5 and the aluminum-plastic composite tape 4 to prevent water vapor from diffusing into the tinned copper wire braided tape 5 and the aluminum-plastic composite tape 4 to affect the shielding effect. The non-woven tape 3 can absorb a small amount of water vapor that has penetrated between the aluminum-plastic composite tape 4 and the non-woven tape 3. The water-blocking powder 13, the water-blocking tape 7 and the non-woven tape 3 can have a good water-blocking effect on the axial connection end of the cable.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
