Description

The electric power connector plug of high transmission speed

Technical field

The utility model relates to a kind of electric power connector plug, is meant a kind of electric power connector plug (PLUG) that meets the high transmission speed of the 6th class (Category 6) standard especially.

Background technology

For adapting to the too later highspeed network applications of network of second, (the Telecommunications industry Associations of America Telecom TIA, TIA) work group, (category 5 at the 5th class standard, Cat.5) wiring system of 100MHz (its title is TSB-67) develops the 6th class (Enhanced Cat.6) standard that a kind of enhancing.And the 6th class standard to performance requirement, also will have more 25% than the 5th class standard except extending to from the 100MHz of the 5th class the 200MHz at least.Therefore, for the test frequency of 6 class performances, even more 250MHz will have been reached.The difference of the maximum of the 6th class and the 5th class standard is to improve its performance aspect the loss of crosstalking and reflux.For the full duplex formula highspeed network applications of a new generation, good backflow drain performance is epochmaking.Crosstalk performance is a factor of grasping best bandwidth.Though at present network set up present situation, still be main flow with 100Mbps, the standard of the 6th class will be more suitable for the demand in future.

The present high speed second too specification standards IEEE802.3u of network (Fast Ethernet) still is with the standard of EIA/TIA-568 as twisted-pair feeder, and twisted-pair feeder is divided into no screen type twisted-pair feeder (Unshielded Twisted Pair according to its structure, UTP) with screen type twisted-pair feeder (ShieldedTwisted Pair, STP), both main distinctions have been more than the STP layer of metal veil and a ground connection copper cash, but because of its price costliness and installation difficulty comparatively comparatively, make the use of UTP comparatively general on the contrary, so general alleged twisted-pair feeder refers to not have screen type twisted-pair feeder UTP more.

Yet on the above-mentioned standard guidelines not only at the high speed communication cable, transfer effect in order in the high speed communication network system, to keep identical high speed, the relevant peripheral equipment of high speed communication cable particularly telecommunication Connection Element (as the joint (PLUG) and the socket (JACK) of RJ-45 type) also must need corresponding design.Employed joint is RJ-45 (comprising PLUG and JACK) in the high speed communication network, and general RJ-45 connector is 8P8C, and 8P refers to 8 grooves (Position), and 8C refers to 8 gold-plated electrode contacts (Contact); But only use two pairs of lines in practical application, other two pairs of lines then can use for equipment such as telephone wire, facsimile machines.The joint of two kinds of specifications of EIA/TIA definition, be respectively EIA/TIA-568A and EIA/TIA-568B, wherein EIA/TIA-568A eliminates, the only surplus latter continues to use, its pin position is respectively Bai Cheng, orange, green, blue, Bai Lan, green, white palm fibre in vain by 1～8 the coating color according to cable of putting in order, with palm fibre.

Design major part is in the past all paid attention to the structure at socket, in the hope of meeting above-mentioned standard, for example No. 224547 of the Taiwan bulletin " the tool noise is eliminated the communications connectors terminal row of ability " adopts the means of contactless stacked arrangement to be improved by each metal pin with socket exactly; Otherwise the improvement design aspect plug (PLUG) is then less.In traditional plug, four to (eight) cable ties up to same plane (Level) and locates to be connected with electrode contact, and the cross-talk of this structure (cross-talk) is higher with the value of backflow loss (return loss), is difficult to meet the standard of Cat.6.

A kind of plug of improvement has been proposed in No. 424353 " with the connector of electric wire carry high frequency data " of Taiwan bulletin; Among this design, each of cable end piece all untied separated to twisted-pair feeder, be connected to each electrode contact via a kind of lead bindiny mechanism then, its characteristic is the order of these separated electric wires to set, drawn abreast within the plug within the framework that is connected to an electric insulation, this framework is separated into two passages at a distance of certain distance up and down by a surface plate, in order to four pairs of electric wires are separated among two passages of Different Plane, each channel end at this framework is provided with electric contacts at last, each bar electric wire is connected to the electrode contact of plug head respectively.

No. 424353 patented technology of above-mentioned bulletin and traditional plug are compared, though existing the improvement still has some following problems:

The original design purpose of l, twisted-pair feeder will reduce noise (Noise) exactly, cross-talk interference such as (Cross-talk), because when the electric current on the line flows, can generate an electromagnetic field, thereby disturb other leads, if positive signal line and negative signal line pair twist, then cancel each other in both magnetic fields of generation, just can reduce interference; But No. 424353 patented technology of bulletin then need be untied electric wire earlier separated in the end of every pair of twisted-pair feeder, lucky like this and twisted-pair feeder original design purpose is disagreed, so can cause cross-talk (cross talk) and backflow loss (return loss) value to raise.

Though 2 severally are respectively in the design of Different Plane in parallel with each other to twisted-pair feeder, its improved effect is still limited.

3, the electric contacts that is provided with at each channel end of framework, its structure are also comparatively complicated.
