Description
One, technical field
The present invention relates to a kind of high speed transmission electric connector socket, relate in particular to a kind of high-speed high-density electric connector socket of the differential signal transmission that can dock with the contact pin connector enforcement of L type end side.
Two, background technology
In electronics industry, use rigging-angle connector realizing being electrically connected between two printed circuit board (PCB)s or between printed circuit board (PCB) and the lead-in wire usually.Rigging-angle connector generally has a large amount of pins and receives terminal, in its right angle orientation, has the pin that is electrically connected with printed circuit board (PCB).Binding post on the printed circuit board (PCB) or binding post connector can be inserted into these pins and receive in the terminal, to realize the electrical connection between them.The transmission frequency height very of the signal of telecommunication by these connectors is not only required in the impedance balance of each contact in the terminal module, reducing signal lag and reflection, and requires to shield between each rows of terminals, crosstalks reducing.
In United States Patent (USP) the 5066236th and No. 5496183, discussed the impedance matching of terminal contact.Rigging-angle connector is also discussed in these patent documentations, thus, standard design make to be produced short or long connector becomes very simple, and need not redesign and the whole new connector of machine work, and only produce a new rack unit, a plurality of same terminal modules are fitted into them.As shown in patent documentation US5066236, can between adjacent terminal module, insert shield member, if do not need shielding, can use insert to replace screen or the thicker terminal module of use to fill the slit that will insert screen so.Disclosed shielded module comprises the tabular screen that is fixed in the module among the patent documentation US5066236, has elastic arm on plate part.But screen is the comparison costliness to processing and assembling.And the screening arrangement among the patent documentation US5496183 need have enough spaces between the adjacent through hole of circuit board, with the short circuit of avoiding causing unintentionally.In addition, if in connector, reorientate ground pin, all must be changed through the module and the screen of insulation processing so.
A kind of optional electric coupler component discloses in No. the 5664968th, United States Patent (USP), wherein each terminal module all has a plurality of plugs, comprise and cooperate contact portion, connector coupling part and the mid portion between them, some of them or all mid portions to be encapsulated in the insulation net.Each module all has conductive shielding layer mounted thereto.Each screen all comprises first elastic arm that at least one is electrically connected with a selected plug in the module that screen is installed, with at least one second elastic arm, this second elastic arm be suitable for electric connector in adjacent terminal module in another selected plug be electrically connected.
Existing arrangements of electric connection, for example disclosed among patent documentation US5066236, US5496183 and the US5664968, be fit to single-ended applications and differential to using.In single-ended applications, a conductor guides whole signals in the first direction upper edge, and in the opposite direction the upper edge is different that conductor returns whole signals then.Each conductor is connected with a joint in the connector assembly, and therefore on first direction by a pin or joint and in the opposite direction by other pin or the whole signals of connector guide.In differential applications, signal is shunted and is transmitted by pair of conductors on first direction.Inverse signal is also also transmitted on a pair of conductor by shunting similarly in the opposite direction.
Single-ended applications has caused the different of characteristics of signals with differential difference to the signal propagation path used.Characteristics of signals can comprise impedance, propagation delay, noise, distortion performance or the like.Characteristics of signals also is subjected to being used to sending the influence with the circuit of received signal.For single-ended and differential applications, the circuit that is used to send with received signal is diverse.The difference of transmission and receiving circuit and signal propagation path produces different electrical characteristics, for example for impedance, propagation delay, distortion and noise characteristic.Can realize the Optimal Signals characteristic that signal is propagated by structure and the configuration that changes connector assembly.
Connector assembly must satisfy the concrete space constraints that depends on application type, as represents the HM connector of industrial standard connector.But the HM connector can not be applied to all fields of expecting better signal operating characteristic.Some connector can supply signal operating characteristic preferably, and as the Z-DOK and the Z-D OK+ 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, technological requirement is high for reducing the difficulty of processing of connector, reducing cost, can provide reliable performance simultaneously, is the development trend of high-speed electrical connectors.At the problem of above-mentioned existence, it is comparatively simple to the present invention proposes a kind of structure, can effectively suppress high speed, high density electrical connector socket that the EM coupling is applicable to differential signal transmission.
Three, summary of the invention
The purpose of this invention is to provide a kind of high speed, high density electrical connector socket that is applicable to differential signal transmission, comprise an insulator foot, a plurality of laminate, a plurality of barricade and a fixed head.Insulator foot is provided with a plurality of guide protrusions, is used to carry laminate, and the end face design of insulator foot is applicable to L type end side contact pin connector docks.Be to cooperate by a plurality of projectioies on the laminate and a plurality of pit to improve intensity between laminate and the laminate, and utilize fixed head that its whole implementation is fixed again, effectively improve the mechanical strength of electric connector integral body.
Advantage of the present invention and beneficial effect are to have reduced crosstalking between the adjacent signals, improve the integrality of connector carrying signal.Improved the mechanical strength of electric connector integral body.
