Fig. 2 has shown that 2 the part 5 that matches of interconnecting is inserted into the interconnection 2 that forms an assembling in the base part 4.Figure 11 has shown the cross section of the interconnection of being done along the hatching 11-11 ' of Fig. 22.There is the zone 105 of a chamfering bottom surface 109 of the part that matches 5, it first be inserted into base part 4.The contact 103 that matches is separated out with the finger 20,30 of aiming at the

contact

16,26 in interconnection 2 base parts 4 and realizes with it being electrically connected.Therefore, the contact 103 that matches will refer to that 20 and second refer to that 30 realize being electrically connected with the mode that replaces and first.The part that matches 5 is pressed into base part 4, installs like this in the groove 82 that projection 102 is received in shell.When interconnection 2 was assembled, its part 5 that matches was seated in the base part 4 fully, provided a horizontal plane to be installed to circuit board thereby the end block of support component 101 106,107 extends beyond the identical level 125 of shell 3 arrival with standoff 113.Terminals 116 at the contact 103 that matches comprise the embodiment that is used for the pin of conductive pads on the contact circuit plate, and the end of pin should be in approximately identical level 125 with standoff.

Fig. 9 illustrates an embodiment of connector, and the insulating support member 101 of the part that matches therein 5 has sidewall 114 and 115, and they are the straight walls with the dimple that holds contact 103, forms a linear set of contact 103.Because

contact

16,26 is mutual lateral shift in the base part shell, so matching of

contact

16,26 refers to that 20,30 have different length (just, contact 26 comprises an extension 33) solving this skew, thus realize being electrically connected with the linear set of contact 103 on the part 5 that matches.In an alternative embodiment, the sidewall 114 and 115 of the support component 101 of the part that matches 5 has the wall of recess profile, and dark and shallow part alternately appears in the length along support component 101 like this.The dimple that is used for receiving contact 103 can show as each dark and shallow part, makes row's contact 103 have the profile (oscillating profile) that waves.In this case, matching of

contact

16,26 refers to that 20,30 can be same or similar mutually, and extension 33 can be optional, because the waving profile and can solve skew between the

contact

16,26 of the extension 33 on the part 5 that matches.

An application of the present invention is that Voltage Regulator Module (VRM) printed circuit board (PCB) is connected to other printed circuit board (PCB)s, realizes the distribution of plate to plate.Specific application is that the VRM printed circuit board (PCB) is connected to the microprocessor printed circuit board (PCB).From the viewpoint of electric property, wish that the resistance of these connectors in using and inductance keep low as far as possible so that the voltage drop by connector minimizes.Resistance can minimize by the material of selecting high conductance and the connector that designs the circuit with short-term road length and heavy in section area.The magnetic field that power/return paths (ground connection) in loop inductance and the configuration produces is proportional.Short line length helps minimum loop inductance.In addition, magnetic field cancellation is the geometry in circuit and loop and a function of separation.Gap between circuit and the ground connection is more little, and it is effective more that magnetic field cancellation becomes, and the loop inductance of connector can be minimized.The loop inductance of connector of the present invention can be for 200pH or still less, compares with the loop inductance of existing connector, and for example in-line connector or blade type and socket connector, it is generally 2nH or higher.

Utilizing coaxial connector to connect two printed circuit board (PCB)s is known in this area, and as at International Application No. WO 01/67512A3 and U.S. Patent No. 6,618,268 and No.6, as described in 623,279, they are incorporated into this with for referencial use.Consult Fig. 2 B of international application, shown in configuration in, first or inner conducting parts 105A provide a circuit or a circuit from the VRM plate to microprocessor board, and second or outside conducting parts 105B provide a loop or a ground path from microprocessor board to the VRM plate.Like this, though the coaxial geometry of this interconnection can provide low inductance, it is not a kind of appropriate method of effectively utilizing the space, for example circuit board real estate.

Utilize in-line connector configuration of the present invention, the demand of circuit board real estate and the demand of distance between plates can be considerably reduced.In the present invention, consult Fig. 3, concerning the pair of contacts that comprises first contact 16 and second contact 26, one in two contacts as circuit or power supply contact, and second in two contacts as loop or grounding component.First and second contact of interconnection in 2 near and the ground connection of intersecting mutually and being caused and the little distance that is subjected to good control between the circuit can produce low-down loop inductance.As shown in Figure 3, interconnection 2 can comprise two power/return paths, and each in them all is positioned at the widthwise edge of housing axis A.Here the interconnection that provides has low-down profile, and the height of the horizontal plane from the fitting surface 12 of shell to the part 5 that matches 125 interconnection of measuring just can be very little, for example, and less than 4mm or less than 3mm.

In an alternate embodiments,

independent contact

16,26 of the present invention can be divided into a plurality of contacts so that extra interconnect to be provided.More particularly, consult Figure 4 and 5, by punishing every contact at a straight line on main part 18 or 28, for example at one or more dotted line, 118,128 places,

contact

16,26 can be divided into two or more contacts.A plurality of contacts (by a dotted line 118,128

segment contact

16,26 and moulding in illustrated mode) must each have at least one finger that matches.The contact that is segmented can be arranged by linear array, and Xi Fen contact is vertically separated and mutual electric insulation therein.First contact of first segmentation of first linear array can be arranged in the interconnection 2 by the mode that is similar to contiguous first contact 16, and second contact of second segmentation of second linear array can be arranged in the interconnection 2 by the mode that is similar to contiguous first contact 26.Just, first linear array still is spaced laterally apart setting with it near second linear array, and first linear array is basically parallel to second linear array.Insulating element can be positioned between first and second array.Like this, can produce the interconnection of two, three, four or a plurality of circuits.The contact of each segmentation can comprise one or more fingers 20,30, depends on application demand.In addition,

contact

16,26 can be adjusted up or down to comprise more or less finger 20,30 than illustrated interconnection here.In addition, the feature of described first embodiment of interconnection can combine to produce other interconnection with the feature of alternate embodiments.For example, independent

adjacent contact

16 or 26 can be used in combination with a plurality of contacts of linear array, here

adjacent contact

16,26 near a plurality of contacts of linear array but be spaced apart with it, the matching of

adjacent contact

16,26 refer to linear array in the finger that matches of a plurality of contacts intersect mutually.Use the present invention's interconnection of a plurality of contacts of linear array easily to customize, allow interconnection to be used to various application.
