Description
[technical field]
The utility model relates to a kind of socket connector, but refers to a kind of modularized socket connector with substrate of electric coupling between the balanced terminals especially.
[background technology]
Socket connector is to be widely used in telecommunication system, and the more extensive network system that is used in of alleged Registered Jack-45 connector.
For satisfying the needs of computer miniaturization development, all corresponding electronic building bricks all need reduce its diameter or size.The Registered Jack-45 connector generally all has eight butt, must reduce its terminal pitch if will reduce the size of this electric connector.But electronic building brick miniaturization meeting produces a negative effect, promptly produces electric coupling between the terminal.When the RJ socket connector is used in low speed signal when transmission, the small electric coupling that is produced between the terminals of adjacent, even can ignore, when the RJ socket connector was used in high speed transmission of signals, the electric coupling that terminals of adjacent produced increased and becomes serious problems.Hence one can see that, unless the electric coupling that is produced between the terminal can be controlled in the acceptable scope, just the Registered Jack-45 connector can be used for high speed transmission of signals.
A kind of solution is that selected pair of terminal is right as differential terminal, at this terminal is internally transmitted the opposite same signal of phase place.The part noise can be weakened in data processing unit like this.
Associative directory as Simon company, its differential terminal with at least eight kinds is right, as T568A, T568B, USOC 4-pair, USOC 1-, 2-or 3-pair, 10base-T (802.3), TokenRing (802.5), 3-pair (MMJ), and TP-PMD (X3T9.5) and ATM.In each classification, right two special terminals of each terminal are close to each other or be separated from each other.Each classification all has its unique distinction, but each is to all producing the electric coupling that must be eliminated.
Above-mentioned all kinds of in, T568A and T568B are widely used, in T568A, it is right that terminal 1,2 constitutes the 3rd terminal, it is right that terminal 3,6 constitutes second terminal, it is right that terminal 4,5 constitutes the first terminals, it is right that terminal 7,8 constitutes the 4th terminal.In T568B, it is right that terminal 1,2 constitutes second terminal, and it is right that terminal 3,6 constitutes the 3rd terminal, and it is right that terminal 4,5 constitutes the first terminal, and it is right that terminal 7,8 constitutes the 4th terminal.
Because these eight terminal pitch equate, so the electric coupling between terminal will inevitably cause some problems, as coupling or cross-talk.With terminal 3 is example, and terminal 3 obtained electrical couplings from its contiguous terminal 2 and terminals 4 originally, and the signal that transmitted of terminal 6 is opposite with the signal phase that terminal 3 is transmitted on the other hand, its terminal 5 also adjacent thereto and terminal 7 formation electrical couplings.But the electrical couplings between terminal 3,6 and the terminal 2,7 but can not be eliminated just, owing to can not set up electric coupling with the electric coupling between balanced terminals 2,3 and the terminal 6,7 between terminal 3,6 and the terminal 1,8.Simultaneously, terminal 3,6 signals that transmitted are owing to the existence of its adjacent terminal 2,7 has noise.Terminal 3,6 also will have the electric coupling that produces owing to terminal 4,5 in addition, and above-mentioned electric coupling must be overcome to prevent to produce some noise.
For reduce terminal 3 and 4,3 and 2 and terminal 6 and 5,6 and 7 between the influence of electric coupling, many methods have been adopted, as set up between the terminal 3 and 1,3 and 5 electric coupling with balanced terminals 3 and 2 and terminal 3 and 4 between electric coupling, set up between the terminal 6 and 8,6 and 4 electric coupling with balanced terminals 6 and 7 and terminal 6 and 5 between electric coupling.
But eight terminals are to be positioned at same plane as mentioned above, are difficult to equilibrium establishment electricity coupling between these terminals of sustained height, as terminal 1 and 3,3 and 5,6 and 4,6 and 8.Equally also can not between these terminals, set up electrical path to produce corresponding electric coupling.
U.S. Siemon company has disclosed a kind of solution at network address http://www.siemon.com/white_papers/99-08-30-through-hole.asp place.At this as a reference.
Shown in Figure 4 as above-mentioned reference, terminal 2 and 6 is positioned at ground floor, and terminal 8,5,4,1 is positioned at the second layer, and terminal 7,3 is positioned at the 3rd layer.The terminal 6 that is positioned at ground floor has a rectangular-shaped loops, and its vertical side aligns with the terminal 4 and 8 that is positioned at the second layer respectively, and the terminal 3 that is positioned at the 3rd layer also has a rectangular-shaped loops, and its vertical side aligns with the terminal 5 and 1 that is positioned at the second layer respectively.
In addition, have a square department on the right edge of the rectangular-shaped loops of terminal 6 and align, have a square department on the limit, left side of the rectangular-shaped loops of terminal 3 and align with the square department of terminal 5 with the square department of terminal 4.
The layout of Siemon company is to be to increase electric coupling between the terminal 1 and 3,3 and 5 and 4 and 6,6 and 8 with the electric coupling between these terminals of balance.But above-mentioned eight terminals four groups of terminals in other words are to be positioned at three aspects, and each group terminal is all isolated by an insulation strip, and this must increase the difficulty that connector is made.
Above-mentioned eight terminals have different structures and moulding, each terminal all has the moulding that is different from other terminal, especially terminal 3 and terminal 6, it is overlapping obtaining required electric coupling all to have rectangular-shaped loops and corresponding terminal, and each rectangular-shaped loops comprises that further square department is to increase the electric coupling between this terminal and the corresponding terminal with square department.The electric coupling that is produced can adapt to the more needs of AS.The terminal of described eight different shapings must increase the difficulty of production.
Have in addition some other method comprising the afterbody route by arranging terminal 3,6,4,5 changing the mutual alignment between the terminal, thereby influence the electric coupling between the terminal 2 and 3,3 and 4,6 and 5,6 and 7.The right route of terminal tails of arranging will increase manufacturing cost.
United States Patent (USP) the 6th, 120 has disclosed another solution to the problems described above No. 329.The structure of its terminal, size also are to differ from one another and increased manufacture difficulty.
United States Patent (USP) the 5th, 069, No. 614 is to adopt a laminate on the socket connector insulating body, however this method is difficult to implement.
