Abstract
A connector with controlled impedance includes at least one set of differential signal terminals with an associated ground terminal. The ground terminal has a symmetric configuration, while the two differential signal terminals have asymmetric configurations. The asymmetric configurations permit capacitive coupling to occur primarily between the two differential signals in an area of the connector where the inductance of the connector would be high. The two differential signal terminals flank the ground terminal.

In an importance of the present invention, the signal terminal of signalling channel and earth terminal are retained triangular relationship in its contact site and body, and therefore, the terminal of respectively organizing that constitutes signalling channel is called as " three unit groups " or " T junction ".This pass ties up to and has made diagram among Figure 12, and in the drawings, earth terminal GB is positioned at the last summit of empty triangle T, and the signal terminal SB1 of this signalling channel and SB2 are positioned at leg-of-mutton following two summits.The importance of this triangular relationship is, the size between signal terminal and earth terminal can change together with the size of the earth terminal of signalling channel, so that increase electric capacity and inductance coupling high between terminal group.The increase of electric capacity will make the impedance of signalling channel reduce.Equally, terminal operation and relative size thereof relative to each other will exert an influence to the inductance of signalling channel, and this also will exert an influence to the impedance of signalling channel.
Having now found that, increase the size of earth terminal, mainly be the surface area that the width of earth terminal will increase earth terminal, and this will increase the signalling channel electric capacity that is caused by the capacitive coupling that takes place successively between two difference signal terminal and earth terminal.Before this, the width of this increase can not be maintained in the vertical body 352 of the earth terminal in the connector of prior art of Fig. 1～shown in Figure 2.Use connector of the present invention, in earth terminal body 352 departs from its coherent signal terminal body 362 or retracts and be preferably located in himself plane from this body 362.Like this, the width W G of earth terminal compares and can increase with the width W S of signal terminal in the body zone, so that have more high surface area.The surface area of this increase will increase the electric capacity of signalling channel, make the total impedance of the connector in this zone reduce.
And, earth terminal keeps triangular relationship with respect to the not coplane interval (that is: earth terminal is positioned at the vertical plane that separates with plane, signal terminal place) of signal terminal, shown in the empty triangle T among Fig. 5, wherein, signal terminal and earth terminal are as vertex of a triangle.Like this, when observing from the rear portion of connector shown in Figure 4, although earth terminal GB can think between two signal terminal SB1, SB2, yet the outward flange OE of earth terminal GB is preferably overlapping with the inner edge I E of its coherent signal terminal.This difference in size has kept being provided with same material in matching area, that is: along the extension of the contact site of connector.This physical relation makes its impedance jumpily be reduced to H11 from amplitude H1 along the line M of Figure 18.
Beyond thoughtly be that earth terminal does not help to make connector of the present invention in the position in the coplanar orientation at it yet.Can become its support terminals module 320,330 separately to two groups of terminal inserted mode systems, first group of terminal, that is: when earth terminal and power supply terminal bend in its second plane, form this two groups of terminals then with bigger reliability.Handle in order to help this formation, as shown in figure 11, this the first terminal also can be molded into support component 370 on it, this support component 370 remains on terminal in its configuration that separates each other, and provide and form the parts contact point, be used for and the contacting of the first terminal group, and this first terminal group is formed into its final position as whole assembly.For the further electric capacity of definition signal passage, can in top or second group of terminal in abutting connection with intervention space " X " the filling dielectric substance between the terminal, normally with molded the first terminal module 320 used identical materials.Can select the dielectric constant of this material, so that between three terminals of each T junction or three unit groups, produce specific capacitor.The body 380 of connector is molded on these terminals, and its material will be filled in the vertical space between earth terminal body 352 and the signal terminal body 362.The dielectric substance that is used for molded body 380 can be selected (" F " that preferably see Figure 15 locates) at the expectation dielectric constant in this zone.
And the signal terminal afterbody of connector and earth terminal afterbody are maintained in the single plane, particularly use (should be appreciated that install in the application at through hole, terminal tails and body can overlap, and also can be positioned at same plane) for mounted on surface.This plane is parallel substantially with the plane of contactor blade portion 350,360 separately.Like this, the invention provides a kind of device, be used for the body of signalling channel terminal and afterbody are remained in two different planes, compare simultaneously, increase the density of connector with the connector in all terminal body are maintained at same level with Fig. 1～shown in Figure 2.
By this structure, each of cable or circuit all has the relative earth terminal separately that extends by connector to difference signal terminal, thereby from the electric property aspect, more approaches cable and relevant pin connector thereof.This structure makes the holding wire of cable adopt same way as in the whole length of cable, and adopts same way as " observation " ground connection substantially by the socket connector interface up to circuit board.This attachment unit interface has been made indicative icon at Figure 18, and with regard to the impedance and electric property of whole coupling assembling or system, this attachment unit interface can think to be divided into four zones of different I-IV.Area I is represented cable 105 and structure thereof, and area I I represents when cable termination during in connector the termination area between cable connector 104 and the cable 105.Area I II is illustrated in the matched interfaces that exists between cable connector and the connector for substrate 110, and it comprises the coupling body of connector 104,110.Area I V represents to be included in the zone of termination between connector for substrate 110 and the circuit board 103.The line of Figure 17 " P ", " N " and " M " are superimposed on Figure 18, thereby can make two figure relevant easily.
The existence of associated ground and signal terminal importantly realizes three capacitive coupling between the terminal.This coupling only is the aspect that the final total impedance to bonder terminal exerts an influence.With regard to the terminal of T junction, resistance, terminal material and self-induction also are the parts that the total characteristic impedance to connector exerts an influence.As mentioned above, and with reference to Fig. 4 and Fig. 5, the width of earth terminal body 352 is even as big as making it and extend on the part of signal terminal body 362 or overlapping with this part at least in part.Preferably, the part of earth terminal always is positioned at least one side's relevant with this signal specific passage the part or is overlapping with this part.In other cases, between the dotted line that earth terminal can draw at the lateral edges from signal terminal, also can join with these dotted lines.The big width of earth terminal in its body compared with the surface area of corresponding signal terminal body and to be had bigger surface area, and therefore, the earth terminal body has bigger overlapping contact matching zone on the zone of signal terminal body.And it is to make earth terminal firmer that the width of the increase of earth terminal in body brings other benefit, and this will be convenient to the formation of earth terminal.
In the earth terminal contact site 350 of the matched interfaces of the area I II that is arranged in Figure 18 and the zone of signal terminal contact site 360, total board size of earth terminal increases with respect to total board size of its coherent signal terminal, thereby optionally reduces the impedance of connector.Equally, in second plane that the both sides by signal terminal body 352 that separates each other and earth terminal body 362 take, interval between earth terminal and its signal terminal increases, and the increase of the size of earth terminal makes when comparing with the connector of type illustrated in figures 1 and 2, keeps the electric effect that electric capacity increases and impedance reduces of this connector.
The effect of this tunability is described in Figure 17, wherein, the minimizing of the total impedance discontinuity that takes place in connector assembly is described.In connector of the present invention, estimate of dotted line 60 expressions of the impedance discontinuity of generation by Figure 17.The solid line of Figure 17 is illustrated in the typical impedance discontinuity of running in the connector system of Fig. 3.By dotted line and solid line being compared the peak value of this discontinuity and the amplitude H of valley
11, H
22And H
33Significantly reduce.The present invention is considered to significantly to reduce total discontinuity of running in conventional connector assembly.In an application, think, the discontinuity of top with about 135 ohm (at H
11), and the discontinuity of minimum level with about 85 ohm (at H
22).The target baseline impedance of connector of the present invention is incited somebody to action about 110 ohm usually, tolerance pact+/-25 ohm.Therefore it is contemplated that connector of the present invention will have about 50 ohm total discontinuity (H
11And H
22Poor), this makes and reduce almost 50% more than from above-mentioned about 90 ohm conventional discontinuity.
Figure 19 shows another embodiment 400 of the terminal structure that can use in connector of the present invention.Present embodiment 400 is that with the different of embodiment of explanation in the past it uses the configuration of asymmetric signal terminal.In the connector of Fig. 3～Figure 16, in fact signal terminal has constant width for its total length in the both sides of its contact site 360 and body 362.Have now found that, asymmetric by making signal terminal along its length, can further control the impedance of connector.This asymmetry has been made diagram at Figure 19 and Figure 20, and in the drawings as can be seen, signal terminal 405 comprises contact site 406, afterbody 407 and body 408, or the transition part 408 that contact site 406 and afterbody 407 are interconnected.Signal terminal contact site 406 and body 408 separate each other, and separate with the contact site and the body of its associated ground 420.Realize asymmetry by making signal terminal 405 have the first preselected width Q that in fact total length of its contact site 406 is extended.Shown in Figure 19 the best, this width reduces or decrescence or be necked up to another width.In signal terminal body 408, width reduces to another smaller value G from width Q, that is: second width, and this width can further reduce to littler value Y from G, is used for the representative width of signal terminal afterbody 408 that is:.
Figure 20 shows the asymmetry that begins from the terminal structure rear portion, and can find out generation change width (from Q to the G) first time in contact site zone 406, and change width (from G to Y) for the second time takes place in the vertical body 408 of terminal.The term of Shi Yonging " asymmetric " or " asymmetry " are presented its common definition in this article, that is to say, if draw the virtual center line along its length by terminal, will be different then in the terminal part of virtual center line opposite sides thereof, be not mirror image each other.These signal terminals are with the different of signal terminal of another embodiment, in signal terminal body 408, there are more materials, this impedance to connector construction exerts an influence, for example, the impedance between the signal terminal (in the differential impedance mode) is opposite with the impedance (in common mode) between signal terminal and its earth terminal.
In connector of the present invention, use the asymmetric signal terminal that useful and beyond thought result is provided.Difference signal terminal mainly is arranged in the zone below the position that the earth terminal width reduces, along the part coupling at all each other of its body.This has made diagram in Figure 20.Earth terminal is along the wider width of its contact site, and raises and signal terminal coplane not, therefore, takes place to reduce and controlled capacitive coupling between earth terminal contact site and two difference signal terminal contact sites.This top area that indicates " coupling " in Figure 20 has been made diagram.The width of earth terminal reduces in the earth terminal body until this constantly, that is: takes place to be coupled between earth terminal and its correlator difference signal terminal at all.
Yet, the width of earth terminal body part reduces to second width in the earth terminal body and in a position, in Figure 19 and embodiment shown in Figure 20, this position above the signal terminal contact site and reduce to from Q first at the width of signal terminal contact site G the position above, carry out the transition to the position of body usually in termination contact portion.Signal terminal should allow in same area by big width along its body, that is: along the minimizing near the zone of difference signal terminal body of the width of the earth terminal of body.By this way, between earth terminal and signal terminal, in its contact site and along its body, be coupled, up to the width minimizing of earth terminal.At this moment, signal terminal and earth terminal " decoupling ", and tentatively coupling each other.This is denoted as " decoupling " in Figure 20.At last, all three terminals are coupled again at earth terminal afterbody and signal terminal afterbody, and here, the earth terminal afterbody and should be denoted as " coupling " in the zone in Figure 20 between two coherent signal terminal tails.
By making earth terminal turn back to the mounting plane identical with signal terminal, that is: in tail region, earth terminal " is coupled " again with two correlator difference signal terminal in the tail region that inductance increases usually.This has appended the coupling in the signalling channel, and has reduced the impedance that is caused by inductance usually and risen.
Although above to the preferred embodiments of the present invention done the diagram and the explanation, yet it will be understood by those skilled in the art that and can change without departing from the spirit of the invention and revise that scope of the present invention is defined by claims.
