The conductor terminal 3 of the curved female connectors of this D type is formed with four rows (A, B, C, D) at terminal external part 12, and at inserted terminal 10, described a plurality of conductor terminals 3 form two rows.
Adjust by the connecting portion 33 to terminal 3, adjust the crooked place and the overbending direction of adjacent two row's terminals, can make adjacent two row's terminal equal in length, as can be seen from Figure 4, A type terminal and Type B terminal are isometric, and C type terminal and D type terminal are isometric.From inserted terminal 10 1 sides, in row's terminal (CDCD...... or DCDC......), each terminal is isometric terminal on it; It is arranged in the terminal (ABAB...... or BABA......) down, and each terminal is isometric terminal.Be A type terminal length=Type B terminal length＜C type terminal length=D type terminal length.And from terminal external part 12, the arrangement of the stitch portion 33 of each terminal 3 in the invention process is identical with arrangement of the prior art, the encapsulation of the curved female plug base connector of D type that can be compatible present fully just need not redesign printed circuit board and just can directly use the improved D type in the embodiment of the invention to bend the female plug base connector.So can, high-speed differential signal is arranged in A/B type terminal, and when transmitting respectively on the C/D type terminal, with regard to the SKEW (length difference) that can not occur causing owing to the right needle tubing pin length difference of each signal pin because of in the prior art, when promptly adopting the curved female plug base connector of D type of present embodiment to come the transmitting high speed differential signal, shake owing to the right different high-speed differential signals that cause of needle tubing pin length of each signal pin can not appear, and the problem of electromagnetic compatibility aspect.
As shown in Figure 5, be the spacing optimization schematic diagram of the connecting portion of terminals of adjacent in the embodiment of the invention; Please refer to the frame of broken lines part of Fig. 4 again, see from the side on dotted portion and the frame thereof and a frame part down that the schematic diagram of whenever adjacent terminal as shown in Figure 5.Illustrated among Fig. 5 a pair of be used for the transmitting high speed differential signal the signal of forming by two terminals to (can be an A type terminal and the Type B terminal that is adjacent as it, perhaps be a C type terminal and the D type terminal that is adjacent).In one embodiment, existing D type is bent the female plug base connector, and at connecting portion 33 places, the horizontal center distance of terminals of adjacent 3 is 1.27mm, and terminal edge distance is about 0.86mm, and the differential impedance between this terminals of adjacent is about 190 ohm; Test shows, reduces this terminals of adjacent edge distance, can reduce its differential impedance, and for example, when terminals of adjacent edge distance was 0.38mm, its differential impedance can be reduced to about 110 ohm.In the embodiment of the invention, each difference signal terminal between differential impedance can be controlled between 80 to 120 ohm.
So in the curved female plug base connector of the D of embodiment of the invention type, terminals of adjacent 3 can be designed to the shape as Fig. 5 at its connecting portion 33 places, there is shown two kinds of shapes: a kind of is the width of widening connecting portion 33 places of terminal 3; Another kind is that connecting portion 33 places of terminal 3 are out of shape, and terminals of adjacent is partly protruded at its connecting portion 33 place's adjacent surfaces, and is more approaching, then shrinks away from face.These two kinds of shapes all can reduce the insulation spacing between the terminals of adjacent edge, thereby increasing electromagnetic field intercouples, allow the differential impedance of terminal of adjacent equal length type reduce near 100 ohm, and because electromagnetic field couples is tighter, can allow the electromagnetic radiation of pin pin diminish, anti-electromagnetic interference capability strengthens.
Fig. 6～Fig. 9 is in the first embodiment of the invention, difference signal terminal schematic diagram is set, it shows the partial schematic diagram of looking up of connector; In an embodiment of the present invention, the curved female plug base connector of D type can be used according to high-speed-differential and be lined up specific combination, be used for the transmitting high speed differential signal, can reduce crosstalking between combination.Its basic principle is to increase to isolate the pin pin, and is interspersed;
In the application of reality, the cable of differential signal transmission generally uses Shielded Twisted Pair or parallel line, and in these cables, each all has a ground wire to differential lines, this ground wire on cable connector usually and differential signal line be close together; In order to reduce crosstalking between signal, high-speed differential signal spatially separates usually in addition, perhaps places shielded metal sheet etc.
For convenience, in embodiments of the present invention, wherein be used at interval or the terminal of ground connection, be called isolation terminal, arrangement is used for the terminal of differential signal transmission, is called difference signal terminal, and it is right that two difference signal terminal that are used to transmit a pair of differential signal are called as a difference signal terminal.In an embodiment of the present invention, isolation terminal can be vacant difference signal terminal, isolation pin or spacer etc.Isolation terminal can ground connection, and is unsettled or connect stationary singnal.
When therefore on the curved female plug base connector of D type of the present invention, carrying out the signal definition arrangement, stretch out face 12 from terminal, pin pin 1 (PIN1#) and pin 2 (PIN2#) are defined as difference signal terminal, it is right to form a difference signal terminal, and (N can be 0,1 every N, 2,3 etc., N=0 is for do not have isolating) isolating pin, to define an other difference signal terminal more right, such as:
N=1, then pin pin 4 and 5 is difference signal terminal, and it is right to form a difference signal terminal, and pin pin 3 is isolation terminals;
N=2, then pin pin 5 and 6 compositions, one difference signal terminal are right, and pin pin 3 and 4 is isolation terminals;
And the like.
When N=0, no isolation terminal can also reach the effect with the N=2 situation with a difference signal terminal to unsettled or ground connection.
Fig. 6 to Fig. 9 shows the situation of N=0 to N=3 respectively.Two pin pins in the oval circle of among each figure each are that a difference signal terminal is right, and other outer pin pins of oval circle are isolation terminal.
Please refer to the content of Fig. 5 again, in an embodiment of the present invention, the connecting portion 33 of the terminal of each difference signal terminal centering can carry out the distortion among Fig. 5, so that the insulation distance between two terminals of a difference signal terminal centering diminishes; And isolation terminal, can be identical with shape of the prior art; Such as working as N=1, the shape of isolation terminal (pin pin 3) can be with of the prior art identical, and just the width at its connecting portion 33 places does not change.
From the curved female plug base connector front view of the D type of the embodiment of the invention, its 10 places, Plug Division are provided with two row's terminals, promptly one of A type terminal and Type B terminal composition arrange another row that C type terminal and D type terminal are formed.In each row, include a plurality of difference signal terminal to and a plurality of isolation terminals, wherein, each difference signal terminal pair is that the space is provided with isolation terminal, i.e. each difference signal terminal pair and at least one isolation terminal space.
And, in the terminal of two rows, the position of difference signal terminal and isolation terminal is to stagger mutually to be provided with, for example, below a row (A/B row) if in begin with difference signal terminal, then one arrange in (C/D row) and begin in the above with isolation terminal, perhaps conversely, A/B row begins with isolation terminal, begins with difference signal terminal C/D row, can make two rows (A/B and C/D row's) the minimum of crosstalking like this.
For example, for DB-68 connector (the D type of 68 pins is bent the female plug base connector), situation at N=2, C/D row's pin pin 1 and 2 is a difference signal terminal, pin 3 and 4 is an isolation terminal, then A/B row's pin pin 35 and 36 is an isolation terminal, and pin pin 37 and 38 are difference signal terminal or the like.Can make so different difference signal terminal between crosstalk be reduced to littler.
To sum up, the D type that the embodiment of the invention provided is bent the female plug base connector, and its impedance continuous type is better, and SKEW (difference in length) is littler, and electromagnetic radiation diminishes, and anti-electromagnetic interference capability strengthens, and it is littler to crosstalk, and is more suitable for the transmission of high speed signal.In addition, only need existing mould is carried out a spot of change, the cost increase is very little, in addition can compatible existing D type pin connector.
In addition, can carry out some changes, can overcome existing problem in the prior art equally the structure of the embodiments of the invention of above-mentioned announcement.
As Figure 10 and shown in Figure 11, be in another embodiment of the present invention isolation terminal schematic diagram is set, it shows the partial schematic diagram of looking up of connector;
With signal terminal according to application packet, two difference signal terminal to isolating N isolation terminal, in the present embodiment, change the width of described isolation terminal, make it become shield blade, be used for ground connection, with a difference signal terminal pair and another difference signal terminal to separating, can reduce equally difference signal terminal between crosstalk.
As Figure 12 and shown in Figure 13, be the schematic diagram that is provided with of an embodiment high speed difference signal terminal more of the present invention.Change the position of pin pin, the adjacent differential signal terminal is made a row at terminal external part 12 places, and be close together, length is the same, can reduce SKEW (difference in length) like this; Equally, can with this to the shape at connecting portion 33 places of high-speed differential signal terminal according to carrying out corresponding change among Fig. 5, reduce the spacing between every pair of differential terminal, promptly on same row, distance between two terminals of same difference signal terminal centering less than two adjacent difference signal terminal between distance, impedance also is reduced near 100 ohm like this; In addition, also can different difference signal terminal between N isolation terminal is set, be staggeredly placed, can reduce crosstalking between the differential signal pin equally, Figure 12 and Figure 13 promptly show the situation of N=1 and N=2.The D type that present embodiment provides is bent the female plug base connector, can be used for the transmitting high speed differential signal equally, and transmission performance and aforesaid embodiment are similar.But because variation has taken place in the position and the layout of the pin pin at terminal external part 12 places, can not be compatible mutually with existing connector, needing to revise printed circuit board can use.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
