Abstract
A kind of eight line two-wire RJ45 network switch heads, this new network switch head has two features, first feature is that outlet and entrance have 8 heart yearns, 2 plain conductors are arranged in each heart yearn wire casing, strengthen circuit contact area, single line loose contact improves contact reliability, as long as can be avoided just to there will be the situation of network failure; Second feature only has 4 cores for communication for 8 core grid lines, the situation that other 4 heart yearns are completely idle, 4 heart yearns of free time are in parallel with 4 heart yearns being used for communicating, avoid single line in grid line to disconnect the situation just likely causing communication failure, improve the reliability of communication further.
Description
Technical field
The utility model relates to a kind of computer networking connection device, particularly a kind of RJ45 network switch head.
Background technology
Network switch head is the one of connector in wiring system, and two netting twines can couple together by it, to facilitate network layout, realize the electrical continuity of wire.RJ45 network switch head is one the most frequently used in network switch head, and known RJ45 network switch head is eight plain conductors, and eight heart yearn one_to_one corresponding in extraneous grid line.But for a local area network (LAN), general service time is longer, in long use procedure, be easy to aging circuit occurs, the situation of loose contact, especially network switch head this grid line wiring place position is being used, more easily there is the situation of loose contact aging circuit, and once there is loose contact in circuit, network failure will be caused, namely the situation of network failure can be caused in order to overcome a certain heart yearn loose contact in existing circuit, reduce the generation of this situation of circuit loose contact in network, the utility model provides a kind of eight line two-wire RJ45 network switch heads, this new network switch head have employed 16 heart yearns and connects, strengthen circuit contact area, as long as single line loose contact can be avoided just to there will be the situation of network failure.
On the other hand, road as known, grid line has 8 groups, grid line 8 groups of lines and network switch head 8 groups of line one_to_one corresponding, but only have 4 groups of lines in these 8 groups of lines for communication, other 4 groups is for telephone wire is reserved at first, but in fact at present almost without any connecting the netting twine of local area network (LAN) simultaneously for connecting phone, that is other 4 groups of lines are idle completely.Although grid line adopts twisted-pair feeder can the mutual crosstalk of anti-stop signal, but through facts have proved, 4 heart yearns of this free time are also completely passable for communicating, for this reason, the utility model, by 4 of the free time groups of lines and the 4 groups of line parallels being used for communicating, improves the reliability of communication further.
Summary of the invention
The purpose of this utility model is to provide a kind of eight line two-wire RJ45 network switch heads, this new network switch head has two features, first feature have employed 16 heart yearns to connect, strengthen circuit contact area, single line loose contact improves contact reliability, as long as can be avoided just to there will be the situation of network failure; Second feature only has 4 groups for communication for 8 networking winding threads, the situation that other 4 groups of lines are completely idle, the utility model is by 4 of the free time groups of lines and the 4 groups of line parallels being used for communicating, avoid single line in grid line to disconnect the situation just likely causing communication failure, improve the reliability of communication further.
For achieving the above object, the utility model is by the following technical solutions:
A kind of eight line two-wire RJ45 network switch heads, comprise entrance, connecting line and outlet, it is characterized in that, described outlet adopts 16 heart yearns, and arrange 2 heart yearns in each wire casing, 16 heart yearns are arranged in 8 wire casings, thus can with existing equipment connection, described entrance also adopts 16 heart yearns; 2 heart yearns are arranged in each wire casing, 16 heart yearns are arranged in 8 wire casings, thus can with existing equipment connection, described connecting line has 8 groups, and wherein 4 groups of lines are used for communication, and other 4 groups of lines are idle, be further characterized in that, 4 groups of idle lines and group line parallel of 4 for communicating, avoid single line in grid line to disconnect the situation just likely causing communication failure, improve the reliability of communication further.
The utility model solves the technical scheme that its technical problem adopts: the every single line in general network adapter is all welded into two lines, connect entrance and exit again, simultaneously, 4 groups of idle lines are directly in parallel with group line of 4 for communicating, avoid single line in grid line to disconnect the situation just likely causing communication failure, improve the reliability of communication further.
The beneficial effects of the utility model are, this new network switch head have employed 16 heart yearns and connects, strengthen circuit contact area, as long as single line loose contact can be avoided just to there will be the situation of network failure, 4 groups of simultaneously idle lines are directly in parallel with group line of 4 for communicating, avoid single line in grid line to disconnect the situation just likely causing communication failure, improve the reliability of communication further.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is general network adapter schematic diagram.
Fig. 2 is the utility model schematic diagram.
Embodiment
With reference to Fig. 2, for a kind of eight line two-wire RJ45 network switch heads of the utility model, this device is all being welded into two lines the every single line in general network adapter, connect entrance and exit again, this new network switch head have employed 16 heart yearns and connects, strengthen circuit contact area, enhance the reliability of wiring circuit contact, as long as single line loose contact can be avoided just to there will be the situation of network failure, simultaneously, 4 groups of idle lines and group line parallel of 4 for communicating, single line in grid line is avoided to disconnect the situation just likely causing communication failure, the further reliability improving communication.
With reference to Fig. 2, the parallel way that 4 groups of idle lines are concrete with group line of 4 for communicating is such, and 8 groups of lines sort from top to bottom and are followed successively by 1,2,3,4,5,6,7,8; Time in parallel, in parallel by 1 and 4; 2 and 5 is in parallel; 3 and 7 is in parallel; 6 and 8 is in parallel.This is because 1,2,3,6 for communication; 4,5,7,8 is idle, so 1 and 4 is in parallel; 2 and 5 is in parallel; 3 and 7 is in parallel; 6 and 8 parallel connections are suitable.
