Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
A kind of high speed connector as shown in Figure 1, be applicable to the high speed connector of 85 ohm, comprise plastic parts 1, brace 2 and metallic support 3, one end of brace 2 is plugged in plastic parts 1, metallic support 3 is positioned at the top of brace 2 and is fixedly connected with brace 2, and brace 2 has terminal assemblies 21 and insulated plastic glue-line 22, and terminal assemblies 21 is positioned at insulated plastic glue-line 22, terminal assemblies 21 is comprised of a plurality of terminals 211, is provided with corrugated bar shaped limit 212 on the side of terminal 211.
On the surface of insulated plastic glue-line 22, offer 221, five holes 221, five holes shape, differ in size, can cause the difference of electric capacity, also can cause the difference of system matches impedance, finally cause the difference of signal transmission; In hole 221, be provided with and a plurality of terminal 211 between spacing match and the strip piece 222 that can be crisscross arranged with a plurality of terminals 211, the making material of strip piece 222 is insulation plastic cement, hole can be through hole or blind hole, or groove.
Signal in high-frequency transmission, hole 221 and bar shaped limit 222 can to signal, the transmission between terminal exerts an influence, thereby affects electric capacity, inductance, causes signal to produce variation.
Terminal 211 is structure as a whole with bar shaped limit 212, by Production of Stamping Die, terminal 211,212Yu hole, bar shaped limit 221 be injection moulding together out.
Embodiment 1:
According to actual conditions, bar shaped limit 212 can be arranged on to segmentation A, segmentation B, any one of segmentation C or tetra-segmentations of segmentation D or two places or three places, can be arranged on arbitrarily on one or two terminals, any one side (with limit relative between terminals of adjacent) that also can be arranged on terminal is gone up or is arranged on two sides of a terminal simultaneously, the length on bar shaped limit 212 can change according to actual conditions, the like, so, by design bar shaped limit, be positioned at the position of terminal, cause the spacing between terminal different, just can realize different inductor design.
On hole 221, appear terminal 211, be provided with strip piece appearing between terminal 211, strip piece has been blocked the spacing between the terminal manifesting 211, signal in high-frequency transmission like this, can exert an influence to signal, thereby affect electric capacity, make it just produce variation.
The different high speed connector of another kind of structure, be applicable to the high speed connector of 100 ohm, comprise plastic parts 1, brace 2 and metallic support 3, one end of brace 2 is plugged in plastic parts 1, metallic support 3 is positioned at the top of brace 2 and is fixedly connected with brace 2 ', and brace 2 has terminal assemblies 21 and insulated plastic glue-line 22, and terminal assemblies 21 is positioned at insulated plastic glue-line 22, terminal assemblies 21 is comprised of a plurality of terminals 211, on the side of described terminal 211, is provided with lug 212 '.
The shape that offers 221, five holes 221, five holes on insulated plastic glue-line 22 is different, differ in size, and can cause the difference of electric capacity, thereby cause system matches impedance different, finally causes the difference of signal transmission; Hole can be through hole or blind hole, or groove.
Embodiment 2:
According to actual conditions, lug 212 ' can be arranged on arbitrarily on one or two terminals, any one side (with limit relative between terminals of adjacent) that also can be arranged on terminal is gone up or is arranged on two sides of a terminal simultaneously, and the length of lug 212 ' can change according to actual conditions, the like, so, by design lug 212 ', be positioned at the position of terminal, cause the spacing between terminal different, just can realize different inductor design.
The setting in hole 221, has manifested the spacing between terminal 211 and terminal 211, signal in high-frequency transmission, signal transmits between terminal, because the shape in hole 221, size and change have produced impact to signal, thereby affect electric capacity, make it just produce variation.
In the situation that interworking interface (being attachment unit interface interface) is identical, in different servers, system matches impedance is not necessarily identical, during system matches impedance, in system, signal transmits most important parameter, if system impedance is not mated, in the high-speed transfer process of signal, just there will be serious crosstalk phenomenon so, signal transmission is unstable, and quality declines.Therefore conventionally for different systems, the parts that need to design different system matched impedance meet the requirement of signal high-speed transfer.Actual in the situation that, mainly to parts by designing different inductance, capacitance parameter meets different system matches impedance requirements.
The change of inductance, capacitance parameter can change (in high frequency by essential attribute and the form of medium (raw material) in theory, insulated plastic glue-line, conductor (terminal) and air are all different media, only their dielectric constant is different), but according to actual conditions, alternative medium (raw material) or to meet the medium that different designs wants few, therefore from medium aspect, consider, restriction is just many.
The present invention passes through in the different structure of terminal design and shape, and the spacing (width) designing between unequal terminal realizes different inductor design; By designing the structure of different insulated plastic glue-lines, design different medium forms and realize different capacitor design.
The present invention, by the design of above different induction, electric capacity, realizes different system matches impedances, and by the difference that dielectric structure is arranged, rather than the difference of the essential attribute of medium realizes the difference of system matches impedance.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
