Two, background technology
Along with the raising of back plate interconnection system transmission speed, require to be used for the electric connector of back plate interconnection system, must be in certain space, carry more faster data signals and do not reduce signal quality.
The connection of signal often distance is very near, occurs undesired crosstalking between the signal of the vicinity that makes.Along with the miniaturization of electronic equipment and the generally raising of data processing speed, crosstalking becomes a key factor of connector design.Reducing the existing method of crosstalking is that the ground signalling pin is set in the signal pins zone.In order to make at a high speed and highdensity connector, the designer has inserted earth shield at approach signal connector place.These earth shields have reduced the electromagnetic coupled between the signal, rational project organization, and shielding can also improve the integrality of connector carrying signal by the impedance of control signal path.
Simultaneously, by to differential signal design electric connector, can obtain the better control of crosstalking.
And, connector assembly must satisfy the concrete space constraints that depends on application type. as represent the HM connector of industrial standard connector, but, the HM connector can not be applied to all fields of expecting better signal operating characteristic. and some connector can supply signal operating characteristic preferably, as the Z-DOK andZ-DOK+ series connector of Tyco company, but possibly can't satisfy the encapsulation requirement of some connector standards.
The connector of patent documentation 03807091 provides a kind of L type earth-shielded structure, and this structure is effectively controlled the EM coupling, but structure is comparatively complicated, the technological requirement height. for reducing the difficulty of processing of connector, reduce cost, can provide reliable performance simultaneously, this also is a kind of trend.
At existing problem, provide a kind of and can satisfy the electric connector that is used for differential signal transmission and has high-quality operating characteristic simultaneously.
Three, summary of the invention
The objective of the invention is to: provide a kind of can satisfy be used for differential signal transmission, and have the high-speed and high-density electrical connector of the band shielding of high-quality operating characteristic simultaneously.This electric connector has a motherboard connector and daughter board connector, and motherboard connector has a pedestal, and this pedestal has a plurality of limiting holes, and a plurality of signal socket connectors are admitted and are fixed in these holes; Pedestal also has a plurality of long and narrow cracking, and is used to hold and fixing a plurality of earth shield sheets; Pedestal is provided with sidewall, is provided with many ribs perpendicular to sidewall, and intercostal is provided with and cracks when cooperating with the daughter board connector, and the guide-localization that is used to hold the daughter board connector is strong, and the earth shield sheet also has the press-fit terminals of bending.The daughter board connector is provided with laminate, three corner steadies, laminate is made up of loam cake, lower cover, signal socket connector, ground shield, ground shield is provided with fixed claw, positioning key, lower cover, loam cake signal socket connector are fitted in together, ground shield is press fit into corresponding side, the laminate that assembles is snapped in the three corner steady draw-in grooves, on cover and be provided with the guide-localization key, when the group connector for substrate inserted motherboard connector, the guide-localization key was inserted in the cracking of rib on the pedestal.
The beneficial effect that adopts the technical scheme of this structure is to make some selected signals avoid the interference of other signal in the pedestal, structure is comparatively simple, guaranteed the reliable contact between signal contacting piece, the earth shield device, had reliable performance, strengthened antidetonation and swing performance
