Description

The RJ45 cable

Technical field

The present invention relates to the comprehensive wiring field, specifically is a kind of RJ45 cable that network connects that is used for.

Background technology

The RJ45 cable is the important the service of connection devices that network connects, and also claims network jumper wire can be called for short netting twine again, and it is the cable that connects network interface card socket, router and the RJ45 socket etc. of computer.

As described in Fig. 1, Fig. 2, the branch line bracket 103 that four pairs of twisted-pair feeders 102 that the RJ45 cable of prior art comprises that outermost insulating sleeve 101, eight heart yearns be wound in twos and Pe material constitute, divide line bracket 103 and four pairs of twisted-pair feeders 102 to be contained in the insulating sleeve 101, dividing line bracket 103 cable length directions along the line to extend and divide the cross section of line bracket 103 is cross, divide line bracket 103 that insulating sleeve 101 inner chambers are divided into four quadrants, be equipped with a pair of twisted-pair feeder 102 in each quadrant.

In the comprehensive wiring process, people are communicated with a plurality of RJ45 sockets with many RJ45 cables with a total router, and the corresponding computer of each RJ45 socket.And above-mentioned many RJ45 cables lean on an end of router to abut one another.This is because though the distance of the different RJ45 socket in office is far away, in this segment distance the office, the RJ45 cables all for the needs that meet reasonable line arrangement abut against together from the machine room at router place.

Because the needs of comprehensive wiring, have to many RJ45 cables are abutted against together, but in case the broadband of every RJ45 cable reaches the 500MHz of standard-required, the RJ45 cable that abuts against together will interfere with each other each other, specifically, twisted-pair feeder in every RJ45 cable can produce with the twisted-pair feeder in the adjacent RJ45 cable interferes, for fear of this interference, people adopt two kinds of schemes, but effect is all undesirable: the one, with the tube wall thickening of insulating sleeve, make the distance increase of the twisted-pair feeder in twisted-pair feeder and the adjacent R J45 cable in the insulating sleeve of every RJ45 cable, reduce to interfere with this, but caused the cost of RJ45 cable to rise significantly; The 2nd, outside four pairs of twisted-pair feeders and branch line bracket, twine one deck insulating tape in addition, and then outside insulating tape, put insulating sleeve, reduce mutual interference between the RJ45 cable with this, but twine the process trouble of insulating tape, can increase labour intensity, increase production cost, and be wrapped in outer insulating tape and can't form perfect regular circular, promptly destroyed the rounding property of whole RJ45 cable, make this RJ45 cable be difficult to be connected with crystal head.

Summary of the invention

The technical problem to be solved in the present invention is, provides a kind of and can prevent to interfere, can not increase considerably production cost again and can guarantee the RJ45 cable of its rounding property.

Technical solution of the present invention is, a kind of RJ45 cable is provided, it comprises outermost insulating sleeve, the four pairs of twisted-pair feeders and divide line bracket, divide line bracket and four pairs of twisted-pair feeders to be contained in the insulating sleeve, divide line bracket to comprise four identical demarcation strips that extend along RJ45 length of cable direction, each side of four demarcation strips interconnects, every demarcation strip is vertical with adjacent demarcation strip, four demarcation strips are divided into four quadrants with the insulating sleeve inner chamber, be equipped with a pair of twisted-pair feeder in each quadrant, divide line bracket also to be provided with four identical support sheets that extend along RJ45 length of cable direction, every support sheet is fixed on the outer end of a demarcation strip, every support sheet along with the center line symmetry of its fixing demarcation strip.

The RJ45 cable of above structure compared with prior art has the following advantages:

Owing to divide line bracket also to be provided with four support sheets that extend along RJ45 length of cable direction, every support sheet is fixed on the outer end of a demarcation strip, every support sheet along with the center line symmetry of its fixing demarcation strip, like this, four support sheets that are separately fixed at the demarcation strip outer end strut the outermost insulating sleeve of RJ45 cable, make the external diameter of insulating sleeve increase, cause twisted-pair feeder in the insulating sleeve of twisted-pair feeder in the insulating sleeve of every RJ45 cable and adjacent RJ45 cable apart from increase, this has just effectively reduced the interference between the adjacent R J45 cable; And RJ45 cable of the present invention does not increase the wall thickness of insulating sleeve, also not be used in the branch line bracket and twine insulating tape outward, so can not increase cost significantly, specifically, prior art is interfered in order to prevent, with the wall thickness increasing of insulating sleeve, like this, the cost of every meter RJ45 netting twine has increase by a relatively large margin, as has increased by 0.15 yuan/meter; Perhaps outside minute line bracket, twine insulating tape, can strengthen labour intensity significantly, also can increase certain cost, as increased by 0.12 yuan/meter; And RJ45 cable of the present invention, though increased by four demarcation strips and increased the girth of insulating sleeve, make cost increase to some extent, increased by 0.06 yuan, but the cost of its increase still increases wall thickness or twines the cost that insulating tape increased less than prior art as the cost of every meter RJ45 netting twine; Again because four support sheets that increase along with the center line symmetry of its fixing demarcation strip, and four demarcation strips are also identical and vertical in twos, and like this, the insulating sleeve of support outside the support sheet remains a circle that rule is complete, can not destroy its rounding property, convenient and crystal head butt joint.

As improvement, four demarcation strips and four support sheets are one, like this, this minute line bracket can utilize the pultrude process moulding, the production efficiency height, labour intensity is low, production cost is low.

As improving again, the gap that exists the confession twisted-pair feeder to pass between every support sheet and the adjacent support sheet, like this, this minute line bracket and the assembling of twisted-pair feeder more convenient.
