Description

A kind of connector with overlapping ground structure
Quoting of related application
The sequence number that the utility model requires on August 28th, 2008 to submit to is that 61/190,374 U.S. Provisional Application is a priority, and this provisional application is by with reference to being incorporated herein by integral body.
Technical field
The utility model is usually directed to high speed connector, more particularly relates to have crosstalking and the High speed rear panel connector of augmented performance of minimizing.
Background technology
High speed connector is used for the particularly telecommunication industry of many data transmission applications.Signal integrity is the important focus in high speed data transfer field, because parts need transmission of data signals reliably.High speed data transfer market is also developed with increase signal density direction to reducing part dimension.
High speed data transfer is used for telecommunication and is received from the data of data storage or parts transmitter with transmission, and this type of transmission betides in router and the server the most at large.Because the industry trends of the size that trends towards reducing, the Signal Terminal in the high speed connector must reduce size, and in order to realize effectively reducing of size, the terminal of connector must be with nearer being disposed on together.Because Signal Terminal more closely puts together, the differential signal terminal of particularly closing between the close at interval Signal Terminal between signal disturb and increase.This is called as " crosstalking " in this area, when its electric field that occurs in Signal Terminal overlaps each other.When high speed right signal of differential signal may be coupled to contiguous or near differential signal right.This has reduced the signal integrity of whole signal transmission system.The minimizing of crosstalking in the high-speed data system is the common-denominator target of high speed connector design.
The minimizing of crosstalking before this, mainly is to realize by the internal shield that use is positioned between contiguous many covers differential signal terminal.These shieldings are relatively large metallic plates of taking on electric field barrier between the row or column of differential signal terminal.These shieldings have increased the size that considerable cost has also increased connector simultaneously to connector.Thereby these shieldings also can increase Signal Terminal reduces connector system to the capacitive coupling of ground connection impedance.If impedance, should be noted that the impedance of guaranteeing the connector system ad-hoc location owing to internal shield reduces and is no more than or drops to below the desired value.The instructions for use system designer that reduces the shielding crosstalk in the connector system is considered to the influence of impedance with to the influence of the size of these internal shields of connector.
Someone has attempted using shielding and has relied on the independent grounding terminal, these terminals shape with big or small aspect differential signal terminal with related identical.Think over the interval of all terminals of the connector system that runs through the whole length of terminal to the instructions for use of the big or small similar grounding terminals of Signal Terminal.When coupling high speed connector interface, impedance and crosstalking perhaps because a large amount of metals of the device on contact both sides and energy is controlled.Because terminal body portion has the configuration different with the terminal contact site and at interval, the impedance in the connector body and the impedance matching difficulty that becomes along terminal body portion.
Therefore the utility model is devoted to overcome the high speed connector of above-mentioned shortcoming, this high speed connector at each differential signal to using a plurality of bigger, discrete shieldings to control to crosstalk and reduce resonance, wherein discrete shielding is collaborative take on other and at terminal arrays along the single shielding of the terminal body portion of connector.
The utility model content
The utility model is because its particular structure realizes these and other target.One main aspect, the utility model comprises and utilizes the back panel connector that is installed in the head connector on the backboard and is used to be installed in the rigging-angle connector on the subcard.When these two connectors linked together, backboard and subcard just were joined together, normally the right angle.
Rigging-angle connector also can be called the subcard connector, is formed by a series of similar connector units.Each connector unit has the insulated frame structure that is formed by plastic cement or other dielectric material mold pressing usually.The a plurality of discrete connector units of these frame supported, each frame supported one conductive terminal array.Each connector unit framework has two independences and contiguous side at least, the terminal afterbody of a lateral support terminal arrays, and the terminal contact site of terminal arrays is supported in the another side.In the main body of subcard connector, the terminal of frame supported to be listed as or to arrange and put, so wherein each unit supports a pair of terminal row thereon.
In each row, terminal is aligned to and makes differential signal to presenting the state of isolation.In each row, for promote the differential signal terminal between edge (difference modes) coupling, the differential signal terminal is to being arranged by edge-to-edge ground.Bigger earth shield terminal at first be arranged in and the differential signal terminal to the row of directly relative vicinity, secondly adjacent (thereon or its down) described differential signal terminal is to being arranged in described row.Like this, the terminal that each differential signal terminal is right in a column border coupled to each other and with comprehensively be coupled in the face of the earth shield terminal in the right adjacent column of this differential signal terminal.The coupling of some edges, the coupling of normal mode just, occur in the differential signal terminal to and close between the position of earth shield terminal in eventually.Bigger earth shield terminal in the connector body can be considered and arrange with a series of shape of falling v, and the described shape of falling v forms by the group of three earth shield terminals is interconnected by a dotted line, and the differential signal terminal is opposite in each of these v shapes.
This framework is the framework that serves as the opening of skeleton or network structure, and it makes the terminal row keep preferred and arranges and the interval.In this respect, framework comprises that cross one another at least vertical and horizontal component and at least one stretching out from the crosspoint are divided into two-part bisector with the area between vertical and the horizontal component.In addition two spokes radially segment these parts once more with the regional aperture area on each the outer surface that forms present connector unit needle stand.These radial spoke networks, with the vertical and horizontal component in basis together, support a series of rib, for bigger earth shield terminal provides the machinery support.This spoke also can preferably be arranged in as being pressed into and load the device be delivered to the compliant pin afterbody, and this is pressed into to be loaded in the subcard connector is assembled into the top that occurs in the subcard connector in the process of subcard.
Radial spoke is positioned on the surface, inside of one of connector unit half needle stand continuously, and is combining when two connector unit half needle stands when making that space length is presented between the terminal row as the stand-off of separating the terminal row.Signal and bigger earth shield terminal constitute at least two bendings in it runs through the scope of connector body, and in these bending areas, the impedance of connector unit is present in the differential signal terminal by minimizing the amount of metal that reaches in the related with it earth shield terminal is controlled.This minimizing realizes by forming big window in the earth shield terminal, and realizes with the distance that increases between the Signal Terminal edge by " constriction " or constriction Signal Terminal main part in Signal Terminal.
This improves also and can carry out in other zone in connector unit, and half needle stand is joined together in this zone.In a preferred embodiment, connector unit half needle stand joins in the hole that is formed on another needle stand half and links together by being formed on post on half needle stand.Above-mentioned window is formed in the big earth shield terminal, with the support spoke of support frame in line, and columnar projections is passed these openings.The necking section that the differential signal terminal is right is also aimed at the support spoke and the earth shield terminal window of connector unit support frame.In this way, alleviate the lateral of differential signal terminal and earth shield terminal in this zone.

Turn to accompanying drawing now, Fig. 1 illustration an execution mode of back panel connector assembly 100, this back panel connector assembly 100 is used for the auxiliary circuit board 102 that is called subcard known in this field is connected to another circuit board 104 that this area is commonly referred to backboard.These parts 100 comprise two connectors 106 and 108.As shown in Figure 2, back panel connector 108 adopts the form of pin, and it has dummy receptacle 110 in four sidewalls, 109 common the qualifications.A plurality of conductive terminals are provided and are fixed in the corresponding terminal receiver hole (not shown) of connector 108 with the form of contact pin 111.Contact pin 111 is for example terminated to conductive trace on the backboard 104 by afterbody, and these afterbodys are fitted to the electroplating ventilating hole that is arranged in the backboard, or pass hole.
Turn to accompanying drawing 3 now, subcard connector 106 is made up of a plurality of discrete connector units 112, and described connector unit 112 covers has the afterbody 113a at the reverse two ends that are positioned at terminal and the conductive terminal 113 of contact site 113b (Fig. 4).Terminal contact site 113b is connected with terminal afterbody 113a by the 113c of intermediate host portion.These main parts 113c runs through the overwhelming majority of connector unit main part, approximately extends to additional upright frame member 135 from basic framework parts 131.Connector unit 112 has its insertion and is formed on protecgulum, or covers the front end 115 of the middle dummy receptacle in 114 (Fig. 3).This cover 114 has the opening 116 of the contact pin 111 of a plurality of aligning back panel connectors 108, so when group card connector 106 inserted back panel connectors 108, contact pin was engaged by the contact site 113b of the terminal 113 of back panel connector 106.Connector unit 112 can be applied to the ribs of the rear surface 118 of connector unit 112, or support 117 is further fixing.
In one embodiment, each connector unit 112 adopts by combination, or merges two (waflets), or the form of the needle stand that together forms of two halves.Right half part needle stand 122 illustrates in Fig. 5 A, and left-half needle stand 121 illustrates in Fig. 5 B.Each half needle stand 121,122 is supported the array of conductive terminal 113 with a specific pattern.When the end of half needle stand that promptly supports terminal contact site 113b from mating end was observed, terminal arrays formed terminal " row " in half needle stand.Like this, when two and half needle stands were mated together, each needle stand or connector unit 112 were supported on a pair of row of terminal 113 spaced in the connector unit 112.This interval provides shown in Fig. 8 B " SP " and by the inside spoke as shown in Fig. 5 A 133 ', 135 ', 137 ', 139,139 ' and 140 '.For reliability, the contact site 113b of terminal 113 as shown in FIG. like that with contact arm to providing.Even this guarantee from two aspects terminal slightly under the situation of misalignment the subcard connector terminal also can touch the back panel connector contact pin.
In one embodiment, terminal 113 is divided into independently Signal Terminal 113-1 and earth shield terminal 113-2.Earth shield terminal 113-2 is used to mechanically Signal Terminal is divided into when connector is worked differential signal, and to be transmitted the Signal Terminal of (be carried) right.Earth shield terminal 113-2 dimensionally greater than each discrete signals terminal 113-1 and on surface area and total overall dimension greater than a pair of this Signal Terminal 113-1, therefore, each such earth shield terminal 113-2 can be regarded as a discrete earth shield that is arranged in the main body of connector unit 112.The size of signal and earth shield terminal and arrangement are shown best by Fig. 7 B, wherein as seen in each half needle stand, earth shield terminal 113-2 is got involved the space and is separated from each other, these spaces hold a pair of Signal Terminal 113-1, and it is aimed at earth shield terminal 113-2 so that the single line arrangement in fact in the terminal row of all terminals 113.Signal Terminal is provided with the Pt spacing, and earth shield terminal and Signal Terminal are spaced apart, and centreline spacing equals about 1.75-2.0Pt.
These Signal Terminals 113-1 is in order to transmit differential signal, and the meaning is that absolute value is identical and electronic signal that polarity is different.In order to reduce crosstalking in the differential signal application, promote or be driven into right differential signal terminal make it coupled to each other or with ground connection coupling be wise, rather than with the single terminal of another differential signal pair or terminal to coupling.In other words, " isolation " a pair of differential signal terminal is desirable with crosstalking under reducing at a high speed.Thereby this be to a certain extent by make earth shield terminal 113-2 in each terminal arrays in half needle stand be offset each other each to Signal Terminal 113-1 or side joint relative with big grounding terminals 113-2 realize.Because the size of earth shield terminal 113-2, it is primarily taken on and is used for the right discrete earth shield of each differential signal that it is faced in the needle stand (or connector unit).This differential signal is to being coupled with earth shield terminal 113-2 with landscape mode (in a broadsidemanner).Two connector units half 121,122 terminal is listed as by a little spacing separates, shown in the SP among Fig. 8 A and the 8B, so for most of length that they run through connector unit, to be 1 air by dielectric constant separate with the terminal in another row of this connector unit the terminal in the row of connector unit.Earth shield terminal 113-2 secondly also take in row or terminal (Fig. 7 B) position thereon or each differential signal under it to the earth shield of the terminal of 113-1.The nearest terminal edges that these differential signal terminals are right is coupled in earth shield terminal 113-2.These two terminals are listed as separating at interval closely together and with the thickness of inner spoke, and this thickness is about 0.25 to 0.35mm, and it is considerable comparing that the such size of other known back panel connector reduces.
Nearly pitch structure has like this promoted the three types interior coupling of each differential signal channel in the subcard connector body: (a) internal edge is coupled, and wherein this right differential signal terminal is coupled to each other; (b) the edge coupling of nearest earth shield terminal in differential signal terminal and the row with half needle stand; (c) differential signal is to the lateral between terminal and the earth shield terminal in half needle stand of facing.This just provides the ground connection return flow path, it is on the specification of discrete signals passage, shown in Fig. 7 B, be considered and have overall V font, if be positioned at differential signal the earth shield terminal of the vicinity on the edge is come the picture dotted line by intersecting in the face of the center on the right earth shield terminal of differential signal.By this structure, each differential signal terminal is to the combination that can have laterally and the edge is coupled, and this combination can help to force the differential signal terminal to internally better difference modes coupling of entering signal.
On bigger overall scope, in connector body, these discrete earth shield terminals are further worked in coordination with the puppet-earth shield that limits a bending in a pair of row in each needle stand.Word " puppet " although use mean that earth shield terminal 113-2 does not have mechanically coupled together, but they still laterally with on the edge direction closely are being in the same place at interval, thereby just as at needle stand, or exist a shielding to carry out electrical action like that in the connector unit.This has extended through whole in fact needle stand, just from the face of bottom to vertical supporting surface, wherein earth shield terminal 113-2 is greater than Signal Terminal 113-1." greater than " mean on surface area and terminal width all greater than.Fig. 7 B illustrates this arrangement best.The opposite edge of earth shield terminal is can be along ground directrix altogether aligned with each other or shown in Fig. 7 B, between the edge of contiguous ground connection, can be furnished with a clearance G STG, and this gap have 7% or a distance still less that is preferably the width G W of earth shield terminal.
Ground shield terminal 113-2 should be greater than its related differential signal at least about 15%-40%, preferably about 34-35%.For example, a pair of differential signal terminal can have the width of 0.5mm, and is separated by the spacing of 0.3mm, forms the combined width of 1.3mm, SPW, and the width of the right earth shield terminal 113-2 of related this signal can have 1.75mm.Earth shield terminal 113-2 in each row separates with interval S and their adjacent signal terminal 113-1, this spacing preferably equals the spacing between the Signal Terminal 113-1, perhaps in other words, all terminals in each row of each half needle stand are separated each other by unified interval S, thereby form preferred coupled mode.
Big earth shield terminal helps to provide a kind of mode to force the differential signal terminal to entering the difference modes coupling, it is described to the inward flange coupling that Here it is, and the edge coupling that helps to remain in this pattern will be reduced to absolute minimum with any coupling of other any Signal Terminal simultaneously.Figure 10 A and 10B illustrate this relation best, are respectively the power strength and the electric field strength curve charts of terminal body portion.Figure 10 A is the power strength curve chart of above-mentioned tlv triple type structure.Drawing of this curve chart is by using ANSOFT HFSS software, simulation is in that illustrative arrangement mode has the cross section of 4 differential signal terminals to the main body of the utility model connector unit of the earth shield terminal 113-2 of 113-1 and 4 subtends among Fig. 7 B, thereby wherein differential voltage is assigned to these two right Signal Terminal 113-1 and produces electric field and power strength.
These analog demenstrations occur in the degree of the coupling in the connector of the present utility model.The value that occurs in the energy field intensity between two terminal edges of each differential signal pair is shown in Figure 10 A, and scope is from 1.6 * 10 -4Joule/cubic meter is to 1.44 * 10 -4Joule/cubic meter, however the value of the energy field intensity between two angled edges of the Signal Terminal centering between the row is decreased to 1.6x10 -5And approach zero, demonstrated the isolation that can realize with the embodiment of specific description.Similarly, it is that the electric field strength of unit and its have shown the field intensity between the right edge of the differential signal terminal of coupling that Figure 10 B represents with volt/rice, and scope is from 8.00 * 10 3Beginning, and the field intensity on the slant path at the right edge of the differential signal terminal of interconnected two adjacency is decreased to 2.4 to 0 volts/rice.

Figure 19 illustrates another embodiment of the element 500 of subcard connector.Connecting element 500 illustrates with the conductive terminal 501 that a plurality of S-S along the line section.Figure 20 illustrates best how different with aforesaid embodiment connecting element 500 is.Although context demonstration and description is rigging-angle connector, yet feature disclosed herein can be utilized in other application such as mezzanine-style connector.
Conductive terminal 501 comprises that paired arrangement is with different Signal Terminal 502 that transmits differential signal and the wide grounding terminals 503 that refluxes and discharge as connector.These terminals are arranged with the form of linear array, perhaps arrange with the form of the row in the right angle application, this application be illustrated as terminal 501 with in each linear array with edge-and further arrange with the pattern of ground connection-signal-signal-ground connection to the mode at-edge.Each is used as differential signal transmission to Signal Terminal 502, and wherein the terminal 502a that terminal is right transmits the positive voltage with given value, and right another terminal 502b of terminal transmits the negative voltage of same magnitude.
As shown in, the width of grounding terminals 503 (is measured acquisition by edge-to-edge, shown in the GW of Figure 21) in fact greater than the width S PW of differential signal terminal to the edge-to-edge of 502a, 502b, and the edge of grounding terminals 503 or the terminal edge of the grounding terminals 503 in the adjacent end array that extends across are to limit an overlapping region between adjacent grounding terminals 503, shown in the left side of Figure 21.In other words, if tangent line " T " along the edge of grounding terminals and the CLV3 that passes the connector unit among center line-Figure 21 draw, they will intersect with the main part of grounding terminals 503.This is overlapping to be preferably the about 15% to 25% of grounding terminals width G W, and more preferably about 15% to 20% of GW.By constriction be present in adjacent signals between hole, connector unit width and increase distance between the right edge of Signal Terminal in the adjacent end array, this is overlapping help be connected each row that the device list supports and each to the terminal signaling in being listed as to being isolated from each other.This has increased the ground connection surface area right with respect to Signal Terminal, this surface area increases the electric capacity in each differential signal transmission or the passage, thereby forces down the impedance of transmission channel and also cause noise littler in the transmission channel and littler the crosstalking of Signal Terminal centering.The bigger width of grounding terminals cause signal between the minimizing of spacing, this signal pair may be leaked.
As described in first embodiment, grounding terminals 503 is partly supported by plastic cement rib 504 along its length, and these plastic cement ribs 504 are by forming with connector half framework 505,506 identical materials.These ribs have the width littler than grounding terminals 503, and they are mainly grounding terminals 503 structural support is provided, but also can be formed to influence the capacitive coupling of Signal Terminal pair and contiguous grounding terminals by the material with desired dielectric constant.
In one embodiment, the grounding terminals 503 that is close to linear array be connected or short circuit together.This connection is shown and occurs among Figure 20 and Figure 21 near the place of front baffle parts 505 with back basic components 507, although this contact may occur over just the place near the front baffle parts, if necessary.The means of contact show as the contact component that adopts push type contact protrusion thing form, and this contact component is bent away from the main part of the grounding terminals 503 in the zone that is close to grounding terminals that overlaps.Figure 23 shows the generation type of thrust 510, and having a spring arm that stops with free end 513 is main part 512, and it preferably has layout smooth contact-making surface thereon.Thrust 510 is pushed by the window 511 from be formed on corresponding grounding terminals 503.Although contact smooth, adjacency has been described, also can use other contact form such as a contact or angle contact.
This common ground structure provides the multiple emission path of (with the electric field of its generation) of induced current in the grounding terminals, thereby helps to reduce the quantity that resonance in the course of the work may take place.Figure 24 be according to Ansoft HFSS software show will occur in contiguous differential signal between the curve chart of far-end cross talk.This is crosstalked and measures between the terminal 502b of two centerings, except also having shown DSP1 and DSP2 among this extra curvature figure.The about 25-29dB of some peaks demonstrations minimizing the on the curve.
Figure 11 A is the contact pin figure that crosstalks that represents as shown in Figure 1 according to the pin layout of the connector of principles of construction of the present utility model.For the corresponding terminal of identification connector, the row of terminal has the alphabetical label that extends along the figure left side, demarcates row and use along the numeral of figure top margin extension.In this way, any contact pin all can be discerned by given letter and number.For example, " D5 " refers to the terminal in " D " row 5 row.Sacrifice the right test of end (victim) differential signal and be by run signal through 4 adjacency in Figure 12, demarcated for " invading end (aggressor) " right differential signal to carrying out.6 around be identical or the mirror image of their counter pair in abutting connection with two of centering, so only test 64 of invading end centerings, this is common in this area.Test is carried out with the paired subcard and the back panel connector that are installed on the circuit board, and the rise time is 33 psecs (20-80%), and it is equivalent to be about 10Gb/ second by the data transmission rate of terminal.Can see as following table, sacrificing end is 2.87% and far-end cross talk (FEXT) is 1.59% to the near-end cross (NEXT) of last accumulation, two values all are lower than 3%, and Figure 11 B is that using along the differential signal terminal of Figure 11 A is differential impedance (TDR) curve chart of the signal imitation of 33 psecs (ps) by connector to H1-J1 and G2-H2 loading rise time (20-80%).
Under the rise time of 33 psecs by impedance that connector assembly and circuit board obtained pact+/-10% for the reference impedance 100ohm of expectation.Each of connector component section quilt is demarcated on curve.Impedance in the transitional region of the subcard connector 106 about 5ohm (with respect to about 103-104ohm) that only rises, wherein the expansion of terminal afterbody is to form terminal body portion, and described impedance to terminal body portion descend about 6-8ohm (with respect to about 96-97ohm) and in the connector unit support frame maintenance cardinal principle constant, wherein big earth shield terminal 113-2 and their differential signal terminal are to linking to each other.When group card connector terminal contact site 113b contacts with the terminal 111 of back panel connector 108, impedance rising about 6-8ohm (with respect to about 103-104ohm), the impedance that spreads all over back panel connector (pin) 108 then reduces to the 100ohm of benchmark resistance value.Like this, will recognize that connector of the present utility model will have low crosstalking in the impedance in keeping acceptable+/-10% scope.
Return Fig. 4 now, each half needle stand has one and supports the insulative support frame 130 that its conductive terminal is listed as.Framework 130 has the foundation 131 of the support 132 that has one or more columns or ear handle shape, and it contacts with the subcard surface in the place that the subcard connector is mounted.It also has vertical front portion 133.These parts can be described with " spoke " and preceding spoke 133 and basic spoke 131 match each other best at this, also limit the border of the main part 113c of terminal 113 simultaneously substantially with the surface of two adjacency of limiting connector unit and skew.The main part 113c of terminal 113 that is to say, wherein earth shield terminal 113-2 extends between basis and preceding spoke 131,133 wide and big zone than their correlation difference sub-signal terminal.
The end that bottom spoke 131 and preceding spoke 133 are sentenced them at the point " O " that is positioned at connector unit 112 front bottom edges is bound up.From then on connect and light, radial spoke 137 is to leave the zone between basic spoke and the vertical spoke 135 this tie-point and extend upward being cut into two-part mode as shown in the figure, and these two parts can equate in case of necessity or be unequal.Radial spoke 137 extends to a position of crossing outmost terminal in the connector unit 112.Attachment spoke is with 138,139 and 140 expressions.In these spokes two, 138 and 139, part is radially in their length range because they the preceding position of tie-point " O " stop and then to different directions extend be attached to vertical before on spoke 135 or the basic spoke 131.If their longitudinal centre line extends, can see that these two radial spokes disperse out from tie-point " O ".The terminal point of these two parts spoke 138,140 radially occurs on the position that intersects with earth shield rib 142, and its structure and purpose below will make an explanation.Be transferred to the top of compliant pin terminal afterbody in order to be pressed into the load that will be added in equably when in place on the subcard 102 on the connector unit at connector unit, radial spoke is also preferably arranged in mode as shown in Figure 4.
The rib 142 of support frame provides support for the earth shield terminal but the runner that also serves as mould is used for carrying the plastics of injection or the material of other any formation connector unit support frame.These ribs 142 are obviously open zone and as the fused mass inlet of spoke with as the fixing point of terminal to support frame in the support frame mould.Rib 142 preferably has the width RW that shows best as among Fig. 8 B, and it is less than the width G W of earth shield terminal.Expectation makes the width of the width of rib 142 less than earth shield terminal 113-2, with influence surface to right edge of the differential signal terminal at the edge of ground connection shield terminal 113-2 and the coupling between their rib 142, thereby the electric field concentration degree at restriction grounding terminals edge can be done consistently with the edge of earth shield terminal 113-2 although have been found that the edge of rib 142.Yet the edge that keeps rib 142 retreats from the edge of earth shield terminal 113-2 so that the connector unit moulding, and reason is that it reduces to form the possibility of mould overflow and influence its electric property thus along the edge of earth shield terminal.The earth shield terminal also provide one in the support frame forming process shaping jig can near reference surface.Shown in Fig. 8 A and when in a commercial embodiment of the present utility model, utilizing, the width range of supporting rib 142 be earth shield terminal 113-2 width about 60% to about 75%, preferred width is about 65% of an earth shield terminal width.
Fig. 4 further shows the additional vertical preceding spoke 135 that is separated and be connected to via expansion 134 connector unit 122 by preceding spoke 133 1 forward.Be somebody's turn to do additional vertical preceding spoke and be centered around they carry out the transition to terminal contact site 113b from terminal body portion the interior terminal in zone.In this transition, the size of big earth shield terminal is reduced to the bifurcated form that can form as the terminal contact site 113b that shows best in Fig. 6 and 9.
Shown in Fig. 5 A, radial spoke 133,135,137,138,139 and 140 can be considered to partly on the surface, inside 150 of one of them of connector unit half needle stand 122 continuously.Row with two terminals 113 together when these elements serve as support and form a connector unit 112 to join at two connector units, half needle stand 121,122 separate each other.Surface, inside among Fig. 5 A 150 illustrations 6 such single spoke member.One is to locate the basic internal spoke 131 ' that intersects with preceding vertical inner spoke 133 at tie-point " O ".Another inner spoke 137 ' roughly extends between two opposite turnings of connector unit half needle stand 122 along the diagonal path direction as a bisection element.In addition two radially, inner spoke 138 ', the 140 ' extension between the preceding inner spoke 131 ' and 133 ' on inner spoke 137 ' and basis of halving.In this preferred embodiment, other inner radial spoke 138 ', 140 ' is positioned between inner radial spoke 137 ' and basis and the preceding inner spoke 131 ' and 133 ', thereby forms the V-type zone that two air can freely circulate therein.Connector unit half needle stand 122 preferably is configured to engage second half with a kind of means, and is illustrated as a plurality of columns 154 in a preferred embodiment.Column 154 is formed in the zone that the differential signal terminal narrows down, and relative with earth shield terminal window 170.Each spoke parts comprises a recess 155 of accepting column 154 accordingly.Inner spoke also is used to provide the isolation SP between the row of the terminal 113 in the connector unit 112 of expectation.In this respect, inner spoke also is used for limiting two V-type air ducts that indicate with arrow 160,161 among Fig. 5 A.The slit 163 that these two V-type air ducts all pass through to demarcate for uppermost terminal in any one connector unit half needle stand opens wide to the outside of connector unit.
Oppositely connector unit half needle stand 121 is shown in Fig. 5 B, comprise a plurality of recesses or opening 155, it is designed to accept the column 154 of second half needle stand 122 and two connector units, half needle stand 121,122 is kept together as single connector unit 112.In the zone that two connector units, half needle stand 121,122 is bound up, the impedance of connector unit 112 is controlled by the amount of metal that minimizing is present among signal and grounding terminals 113-1, the 113-2.This minimizing realizes by form window 170 big, preferred rectangle in the 113c of terminal body portion in earth shield terminal 113-2, and the 113c of terminal body portion holds the plastic cement of column 154 and connector unit half support frame simultaneously.Preferably, these windows have 1.2 aspect ratio, and wherein on one side (1.2) are 1.2 times of another side (1.0).This reduces in Signal Terminal by " constriction " Signal Terminal main part 113c, thus two types extended region or opening 171,172 occur in respectively the differential signal terminal to and this right terminal 113-1 and earth shield terminal 113-2 between.In this zone the constriction increase differential signal terminal of terminal body portion between the distance of edge-to-edge, thereby influence its coupling, be explained as follows.
Window 170 is formed in the edge of earth shield terminal 113-2, and terminal length because two as among Figure 13 best the sidebar 174 of same constriction of demonstration be continuous via window area.Preferably, window 170 has 1.2 aspect ratio (high/wide).Constriction between earth shield terminal 113-2 and the adjacent differential signal terminal 113-1 limits by two opposite recesses in the edge that is formed on signal and earth shield terminal 113-1,113-2.Shown in the viewgraph of cross-section of Figure 13, recess 175 is formed on the relative two edges of earth shield terminal 113-2 in the zone of window 170 and can extends across the lateral edges 170a of window 170 slightly.Other recess 176 is formed on the edge of Signal Terminal 113-1, so the width of Signal Terminal 113-1 reduces the width RSW that is reduced at window from their normal main part width S W.The width (Figure 12) of the opening NW of the constriction between right two terminals of differential signal preferably is equal to or greater than Signal Terminal width S W, and preferably necked width is greater than the Signal Terminal width, and its value is no more than about 10%.
This structural change is effectively, thereby minimizes the interruption of any impedance that may take place because of the flip-flop of dielectric (from the air to the plastic cement).Signal Terminal 113-1 is by constriction when rectangular window 170 is cut cross-under ground shield terminal 113-2.These changes have increased edge coupling physical distance and have reduced the lateral influence, change with the dielectric of compensation from the air to the plastic cement.In window area, the part of the metal of big earth shield terminal is replaced by the plastic cement dielectric in the window area, and in this zone, the width of Signal Terminal 113-1 is reduced so that their edge moves further to separate and hinders and the lateral of earth shield terminal and promote edge coupling between the differential signal terminal 113-1.The increase of the edge spacing of the Signal Terminal 113-1 in this path along open window 170 causes distance that the differential signal terminal separates as them and identical electrical operation in their regular width segments.Interval between the Signal Terminal of two constrictions has the plastic cement of the dielectric constant higher than air abrim.This plastic cement filler will be used to be increased in the regular signal terminal to the Signal Terminal at marginating compartment place between coupling, but by in this zone, making them be moved further separation, Signal Terminal is identical with the distance interval in regular domain at interval as their distance to the electrical characteristic in the work, thereby the coupling between them is remained on any impedance discontinuity that identical level minimizes the place, installation region simultaneously.
Turn to Figure 14-18 now, according to an importance of the present utility model, the main part 113c of ground connection and Signal Terminal 113-1 and 113-2 has irregular coplane shape, its afterbody 113a that allows signal and grounding terminals 113-1,113-2 can make the position of the right terminal 113-1 of above-mentioned differential signal concern the relation that is in the face of the big grounding terminals 113-2 separately in the adjacent column of half relative connector unit simultaneously to unify pitch arrangement.Can see, the main part 113c of the signal of each row of terminal and grounding terminals 113-1,113-2 is aligned with each other with coplanar relation, simultaneously, the main part that is divided the terminal in the row of each connector unit of half with respect to the main part of the terminal in another row of half connector unit with identical preset distance " t " layout (Fig. 7 B and 15).Distance " t " is the separating distance between the terminal of opposing connector needle stand.Because grounding terminals 113-2 has the lateral width bigger than Signal Terminal 113-1, the longitudinal centre line 113d of the main part 113c of signal and grounding terminals 113-1,113-2 does not have equal spacing (Figure 18).In fact, as shown in figure 18, spacing between the longitudinal centre line 113d of the main part 113c of Signal Terminal 113-1 is a distance ' ' d ' ', and the spacing between the grounding terminals 113-2 of the longitudinal centre line 113d of the main part 113c of Signal Terminal 113-1 and vicinity is 1.78d.
Consistent with the utility model, although the spacing of the center line 113d of the main part 113c of signal and grounding terminals 113-1,113-2 is unequal, the installation afterbody 113a of ground connection and Signal Terminal still arranges with the uniform array of row and row so that many-sided and use effectively.For this reason, the afterbody 113a of signal and grounding terminals 113-1,113-2 opens predetermined different distance from terminal longitudinal centre line 113d laterally offset separately, and signal and grounding terminals 113-1,113-2 are formed with recess or the neck that convenient terminal is installed with the nested relation of side direction each other, and wherein consistent interval or spacing is necessary between the afterbody 113a of the terminal of each row.The interval of this unanimity can be square interval, preferably the interval of rectangle.In illustrative embodiments as seen in Figure 18, can see the Signal Terminal 113-1 on the right hand distally, as seen in Figure 18, open a relatively little distance " k1 " from the longitudinal centre line 113-d laterally offset of terminal, and the afterbody 113a of another Signal Terminal 113-1 of differential pair offsets a bigger distance " k2 " from the center line 113d of the main part 113c of terminal, and the afterbody 113a of grounding terminals 113-2 offsets a distance " k3 " from the center line 113d of grounding terminals simultaneously.In this case, the side offset distance of grounding terminals 113-2 " k3 " less than the side offset distance " k2 " of contiguous Signal Terminal greater than the side offset distance " k1 " of another right Signal Terminal of differential signal.
For facility has the placement of the afterbody of so consistent spacing, in this case each among signal and grounding terminals 113-1, the 113-2 on its sidepiece or edge side, be formed with a horizontal recess or neck 113e with the skew that allows desired afterbody 113a with nested.Among the embodiment that shows in Figure 18, for example, grounding terminals 113-2 is formed with a pair of recess or neck 113e and the afterbody 113a of closing signal terminal 113-1 is nested among the recess 113e in the following mode of the main part 113c that is in grounding terminals 113-2.As will be understood by the skilled person in the art, when they extended through the dielectric installation frame of half connector unit, such degree of opening recess or constriction of terminal 113-1,113-2 can influence by the mode that keeps the right Signal Terminal suitable resistance control of each differential signal.
According to the further aspect of the utility model, the afterbody 113a of signal and each row of grounding terminals 113-1,113-2 separates with the afterbody 113a of consistent horizontal spacing from the adjacent column of terminal, and this horizontal spacing is different from the horizontal spacing between the main part 113c of terminal of each connector unit.In illustrated embodiment, the afterbody 113a of each signal and grounding terminals 113-1,113-2 by one horizontal, the horizontal flanges 113f of portion (Figure 15 and 18) supports substantially, this flange part 113f from main part 113c extending, so the afterbody 113a of each row of signal and grounding terminals has greater than the horizontal spacing " t1 " of the horizontal spacing " t " between the main part 113c of the signal of connector unit and grounding terminals (Figure 15) with relation that the terminal of relative half connector unit becomes to disperse.The signal of half relative connector unit and the afterbody main part 113c of grounding terminals also with the connector unit of direct vicinity in the signal horizontal spacing t1 identical with the lateral separation of the row of the afterbody of grounding terminals arrange.
Therefore, the afterbody 113a that can see the ground connection of connector unit and Signal Terminal is with consistent arranged in arrays, comprise the row of the afterbody 113a that spacing equates, and the afterbody of each row also is equally spaced.In illustrated embodiment, the afterbody of each row of terminal is spaced apart by the spacing " p " with 1.35mm, and the row of afterbody are spaced apart by the horizontal spacing " t1 " with 1.90mm.The spacing of these spacings and Width is obeyed about 0.71 aspect ratio; T1 (equaling above-cited WW) is so approximately be minimum can realizing by the spacing on the printed circuit board (PCB) of mounted connector.
Although preferred embodiment of the present utility model is shown and describes, obviously those skilled in the art can carry out changes and improvements under the situation of the claim restricted portion that does not break away from spirit of the present utility model, added.
