Abstract
An electrical connector for overlapping grounded complementary shielded differential contact pairs for high speed transmission includes a header connector having a base, a ground shield blade and differential contact pairs. Wherein the base has mating guide slots and defines the array positions of the ground shield and differential contact pairs; each differential contact pair is arrayed according to a certain row spacing and a certain column spacing; the ground shield pieces form complementary shielding by positive and negative combination, overlapping, staggered layers and other arrangement modes. The complementary shielding method enables the differential pairs to be mutually isolated, so that a plurality of non-congruent differential pair sections are isolated, and the purposes of controlling the impedance of the differential pairs, reducing the mutual crosstalk and the like are achieved. The non-congruent differential pair sections are arranged in a cross way, and the arrangement is symmetrical about the central point of the bottom surface of the base, so that the use is convenient and the expansion is easy.
Description
One, technical field:
The present invention relates in the interconnection systems such as telecommunications, between the printed board and the electric connector that is connected between printed board and the lead, relate in particular to the right electric connector of overlapping ground connection complementary shielding differential contact elements.
Two, background technology
In the electronic interconnection system, raising along with field devices such as electronics and communication and system works frequency, requirement to connector is also more and more higher, from only realizing simple electrical communication at first, need to satisfy the high-speed interconnect requirement of Gbps level data transmission rate till now, experienced development and the renewal of number for product.Problems of Signal Integrity such as this novel high speed transmission connector needs that can satisfy Gbps level data transmission rate solve such as impedance, shield, crosstalk, reflection and time delay.
Set forth the metallic shield problem among the open 49-6543 of Japan's special permission of Fujitsu Ltd.'s submission in 1974, that is the early stage use of metallic shield technology.
Discussed about being applied to the metallic shield problem to signal contacting piece in the connector in No. the 4632476th, the laid-open U.S. Patents in 1986, the design that has disclosed a kind of connector has wherein been used metallic shield between the signal contact row.
Disclose a kind of connector construction in nineteen ninety No. the 4975084th, the laid-open U.S. Patents, this connector adopts and insert the signal integrity that earth shield sheet method is improved connector between adjacent signals contact row.
Impedance Control and matching problem about being applied to the signal contacting piece in the connector have been discussed in the United States Patent (USP) of announcing respectively at 1991 and 1996 No. 5066236 and No. 5496183.
A kind of connector construction is disclosed in No. the 6231391st, United States Patent (USP).This connector comprises a pedestal, a plurality of signal pins, a continuous band and a plurality of grounding pin, wherein band has a plurality of shielding blades continuously, a plurality of shielding blades are according to the shape moulding of right-angle cross-section, keep apart each signal pins, thereby be corresponding ground shield of each signal pins outfit.
Similar above-mentioned those connectors of mentioning, such as patent documentation 4632476,4975084,5066236,5496183 and 6231391, there are deficiency and defective at aspects such as transmission rate, shield effectiveness or Project Realization expenses, are difficult to satisfy higher level demands such as two-forty, high density and low cost.
On the other hand, the package dimension of connector often defines its concrete application scenario.Although the connectors such as HS3, Z-DOK that Tyco electronics, inc. produces show the higher signal characteristic, its transmission rate has reached 6.2Gbps even more than the 10Gbps, but because package dimension is incompatible, they may not be applied in the computer interconnected systems at Compact PCI specification.
A kind of optional electrical connector plug discloses in Chinese patent 1643742A (application number is 03807091.X), and this electric connector has adopted L shaped in the same way mask array, and each differential pair is kept apart, and has formed the differential pair cross section array of a plurality of congruences.But, because L shaped in the same way mask array does not structurally have symmetry, this connector has certain inconvenience in the concrete operations of using; The quantity of its earth shield sheet is more simultaneously, and efficiency of assembling is on the low side.
In sum, existing problem is how a kind of the satisfy little package dimension of differential signal interconnection needs, electric connector solution more economical, that have the quality signal operating characteristic and be user-friendly to simultaneously are provided.
Three, summary of the invention
Purpose of the present invention, a kind of impedance that is applicable to high speed transmission of signals and each differential pair of control is arranged is provided, reduces it and crosstalk each other, with overlapping ground connection, the right electric connector of complementary shielding difference contact that guarantees its quality signal operating characteristic, it comprises a pin connector, and this connector has pedestal, earth shield sheet and differential contact elements.Pedestal is wherein had the butt joint gathering sill, and limit above-mentioned earth shield sheet and the right array position of differential contact elements; Each differential contact elements is right, carries out array by certain line space and column pitch; Each earth shield sheet forms complementary shielding by modes such as positive and negative combination, overlapping and staggered floors.The method of this complementary shielding, make above-mentioned each differential pair between row, column, isolate mutually, thereby isolate a plurality of non-congruent differential pairs cross section, cross arrangement between this non-congruent differential pair cross section, this arranges the central point about base bottom surface, and is easy to use and be easy to expansion.
The beneficial effect that adopts the technical program is can satisfy the differential signal interconnection to require little package dimension, has quality signal, reduces it and crosstalks each other, to guarantee the quality signal operating characteristic.
