Abstract
The present invention relates to a kind of high-speed-differential connector of differential characteristic impedance high, under the premise of the total spacing for ensureing high-speed-differential bonder terminal is constant, the positive pole and the spacing of negative pole of each differential pair in appropriate increase each column, the simultaneously appropriate spacing for reducing each difference positive and negative electrode and connector ground terminal in each column, and terminal spacing is constant in keeping often going, non- equidistant differential pair arrangement is formed, the differential characteristic impedance of each differential pair is improved.The present invention can simply, it is quick, effectively improve bonder terminal and the differential characteristic impedance of printed board via junction, while terminal occupies little space, total spacing of bonder terminal is not increased, do not increase take printed board using space.
Description
Technical field
The invention belongs to differential characteristic Technology of ZO control, and in particular to a kind of high-speed-differential of differential characteristic impedance high connects
Connect device.
Background technology
Conventional high rate differential connector terminal arrangement mode generally is equidistantly arrangement, as shown in figure 1, all adjacent columns
Spacing be m, the spacing of all adjacent lines is n.By taking terminal 1,2,3,4 as an example, terminal 1 and 4 is ground connection, terminal 2 and end
Son 3 is a pair of difference, and terminal 3 is the positive pole of difference, and terminal 2 is the negative pole of difference.Terminal 1 and the line space of terminal 2, the and of terminal 2
The line space of terminal 3, terminal 3 and the line space of terminal 4 are n.By taking 9 trip link actuators as an example, the total a height of 8n of terminal.
For the weldering connector terminal structure mode that is press-fitted or perforates, bonder terminal need to load in printed board via, therefore one
As printed board via diameter it is relatively large, according to transmission line theory, this can cause bonder terminal and printed board via junction
Differential characteristic impedance it is relatively low, cause the mismatch of impedance, have impact on the transmission of signal.The arrangement of convention connectors terminal is general all
It is equidistantly arrangement, then correspondence printed board is also accordingly fixed to used hole site, is equidistantly arrangement.According to transmission lineation
By if it is desired to the differential characteristic impedance of raising bonder terminal and printed board via junction, increases connector end at equal intervals
The spacing of son is fast and effectively method, but it is as follows also to have many drawbacks：
1) total spacing of bonder terminal is increased；
2) space shared by bonder terminal is increased；
3) reduce printed board using space.
The content of the invention
The purpose of the present invention is：Under the premise of the space for not increasing terminal occupancy, a kind of high-speed-differential connector end is invented
The non-equidistant differential pair arrangement mode of son, the difference for improving high-speed-differential bonder terminal and printed board via junction is special
Property impedance.
In view of the above mentioned problem of prior art, according to one side disclosed by the invention, the present invention uses following technology
Scheme：
A kind of high-speed-differential connector of differential characteristic impedance high, it is characterised in that due to differential pair positive pole and negative pole it
Between spacing it is big to differential characteristic impedance influences, and the spacing between differential pair positive and negative electrode and ground connection is to differential characteristic impedance shadow
Sound is small, during arrangement between each terminal for carrying out high-speed-differential connector, ensure high-speed-differential bonder terminal it is total between
Under the premise of constant, the positive pole and the spacing of negative pole of each differential pair in appropriate increase each column, while every in suitably reducing each column
The spacing of individual difference positive and negative electrode and connector ground terminal, and keep often go in terminal spacing it is constant, formed it is non-at equal intervals it is poor
Divide the differential characteristic impedance that each differential pair is improved to arrangement.
Beneficial effect：
The high-speed-differential connector of differential characteristic impedance high of the invention, can simply, it is quick, effectively improve connector end
Son and the differential characteristic impedance of printed board via junction, while terminal occupies little space, total spacing of bonder terminal are not increased,
Do not increase take printed board using space.
Brief description of the drawings
Fig. 1 is the equidistant difference arrangement example of convention connectors terminal.
Fig. 2 is the non-equidistant difference arrangement example of bonder terminal of the present invention.
Specific embodiment
The present invention is described in further detail with reference to embodiment, but embodiments of the present invention not limited to this.
The present invention is described in further details below.A kind of high-speed-differential of differential characteristic impedance high proposed by the present invention
Connector, because the spacing between differential pair positive pole and negative pole is larger to differential characteristic impedance influences, and difference both positive and negative polarity and connects
Spacing between ground is relatively small to differential characteristic impedance influences, therefore by increasing the positive pole of differential pair and the spacing of negative pole, together
When reduce the spacing for connecing difference both positive and negative polarity and ground connection, under the premise of the total spacing for not increasing terminal, form non-equidistant difference
The purpose for improving differential characteristic impedance is reached to arrangement.
Such as Fig. 2, by taking terminal 11,12,13,14 as an example, terminal 11 and 14 is ground connection, and terminal 12 and terminal 13 are poor a pair
Point, terminal 13 is the positive pole of difference, and terminal 12 is the negative pole of difference.Terminal 11 and the line space of terminal 12 are n-a, terminal 12 and end
Son 13 line space n+b, terminal 13 and the line space of terminal 14 are n-a.By taking 9 trip link actuators as an example, the total height of terminal is still 8n, and is schemed
1 head office is high identical, but the differential pair that is formed of terminal 12 in Fig. 2 and terminal 13 is than difference that terminal in Fig. 12 and terminal 3 are formed
To differential characteristic impedance will height.
How to ensure to be arranged using non-equidistant differential pair on the premise of total spacing is constant is the key implemented, such as Fig. 2,
With 9 trip link actuator behaviors example, a height of 8n of terminal head office is high with Tu1Zhong head offices consistent.Head office 8n high in so Fig. 2 is terminal
Line space sum, you can obtain 8n=(n-a)+(n+b)+(n-a)+(n-a)+(n+b)+(n-a)+(n-a)+(n+b), then carry out
When terminal is arranged, appropriate increase or the ratio for reducing are a=3b/5.For the connector of other total line numbers, principle and algorithm can
With by that analogy.
