Common ground shielding 100 may be provided at mating interface 30, and including shielding body 102 with holes, shielding is originally Body 102 when being connected device housing 31 and supporting along can be substantitally planar by longitudinal L and transverse direction the T plane limited, and Biased relative to the respective column CL limited by signal electrical contact 35, so as to shield not Contacting signal probe 35 of body 102.First electricity Connector 22 includes the multiple ground connection installation ends 104 stretched out along a first direction from shielding body 102.It is grounded installation end 104 can with shielding body 102 it is integrated or can with shielding body 102 separate, so as to when shielding body 102 by connector shell Ground connection installation end 104 is electrically connected with shielding the second end of body 102 during 31 support.Being grounded installation end 104 can be with signal electrical contact 35 installation end 40 can be press-fit tail end along common column CL aligned in general, and tail end, or fusible element are installed in surface Such as tin ball, ground connection installation end 104 is configured to be electrically connected to complementary electric device such as first substrate 26.

Common ground shielding 100 can be supported by connector shell 31 so that being grounded installation end 104 is arranged along horizontal T It is adjacent with a pair of installation ends 40 of adjacent signal electrical contact 35 or be arranged between the pair of installation end 40.For example, public The ground connection installation end 104 of earth shield 100 and the installation end 40 of signal contact 35 can be by the mounting interfaces along electric connector 22 32 along common column CL spaced at equal intervals.According to one embodiment, ground connection installation end 104 may be disposed at restriction along between common column CL Every adjacent Difference signal pair 45 signal contact 35 installation end 40 between.Therefore, configured according to contact, the first electrical connection Device 22 can limit the G-S-S patterns of repetition, wherein " G " represents a ground connection installation end 104 of common ground shielding 100, and " S " represents an installation end 40 of signal electrical contact 35, wherein, two adjacent " S " in the G-S-S repeated can represent difference Signal to 45 signal contact 35 installation end 40.It should be understood that the first row in row CL can be limited from row CL top nematic CL's The G-S-S of the repetition of bottom the first contact configuration, and can be limited with the secondary series in the adjacent row CL of first row in row CL Surely it is different from the second contact configuration that the first contact is configured.For example, the configuration of the second contact can limit the top nematic CL from row CL Bottom repetition S-S-G.So, laterally A row CL can limit the first He of the repetition across the first electric connector 22 Second contact configuration (and also along lateral A across the second electric connector 24, should be understood that from following detailed description).It is optional Ground, the configuration of the second contact can be identical with the first contact configuration.

First electric connector 22 also include it is multiple ground connection abutting ends 106, ground connection abutting end 106 from shielding body 102 along Second direction stretches out, and second direction is opposite with the first direction that ground connection installation end 104 extends from shielding body 102.Ground connection Abutting end 106 can be integrated with shielding body 102 or can separated from shielding body 102, with when shielding body 102 is by connector Ground connection abutting end 106 is electrically connected with shielding the second end of body 102 when housing 31 is supported.Being grounded abutting end 106 can be with signal electricity The abutting end 38 of contact 35 is configured to when the first and second electric connectors 22 and 24 phases along common column CL aligned in general The complementary fit end of the earthing component 59 of the second electric connector 24 is electrically connected to during cooperation.

Being grounded abutting end 106 can be along longitudinal L and the ground connection substantially collinear of installation end 104, so that along the line of longitudinal L extension Can be by a ground connection abutting end 106 and a ground connection installation end 104 of alignment.Ground connection abutting end 106 is arranged at along horizontal stroke To between a pair of abutting ends 38 of T signal contact 35.Be grounded abutting end 106 can along horizontal T and signal contact 35 cooperation End 38 is aligned, so that the line extended along horizontal T can be by ground connection abutting end 106 and the abutting end 38 of signal contact 35.It is similar Ground, ground connection installation end 104 can be aligned along horizontal T with the installation end 40 of signal contact 35, so that can along the horizontal T lines extended By the installation end 40 for being grounded installation end 104 and signal contact 35.It is grounded abutting end 106 and abutting end 38 can be along common column CL Along the equi-spaced apart of mating interface 30 of electric connector 22.Correspondingly, ground connection abutting end 106 can be arranged at phase along common column CL Between adjacent Difference signal pair 45.As described in more detail below, each ground connection abutting end 106 can be limited by respective rib 124, rib 124 from shielding body 102 towards with being grounded the corresponding public of the signal contact 35 that installation end 104 and ground connection abutting end 106 are aligned Arrange the outside projections of CL.

Shielding body 102 can be at least partially in relation to corresponding common column CL laterally A biasing.For example, shielding body 102 It can generally along the plane extension on corresponding common column CL Strategic Lateral Offsets, and therefore by relative to signal electrical contact 35 and connecing The Strategic Lateral Offset of ground installation end 104.According to illustrated embodiment, it is for example many that shielding body 102 includes at least one the first noumenon component Individual the first noumenon component, the first noumenon component can be configured as the first beam 108, and beam 108 can be along can limit longitudinal L first party To elongation.So as to which each first beam 108 can extend along longitudinal L between ground connection installation end 104 and ground connection abutting end 106.

First beam 108 can limit the opposite transverse edge 112 for example along horizontal T intervals.Thus, each first beam 108 can limit along the horizontal T first sizes extended between outer lateral edges 112 or width W1.The first adjacent beam 108 It can be spaced apart along second direction first apart from D1, the second direction can be on first direction angle offset, such as substantially Vertically.According to illustrated embodiment, second direction can limit horizontal T.For example, second distance D2 can be defined to the first adjacent beam Between 1 08 adjacent transverse edge 112.It should be appreciated that when the first width W1 increases first can accordingly reduce apart from D1, and When the first width W1 reduces, first can accordingly increase apart from D1.First beam 108 can be with corresponding ground connection installation end 104 and ground connection The longitudinal direction of abutting end 106 is conllinear, and therefore can be equally spaced between adjacent signal electrical contact 35, and specifically sets It is set to adjacent with Difference signal pair 45 and is arranged between Difference signal pair 45.According to illustrated embodiment, the first beam 108 is set It is placed between the body 39 of signal electrical contact 35 and its is adjacent.It is for example many that common ground shielding 100 limits at least one hole 110 Individual hole 110, in a position, laterally A extends through shielding body 102 in hole 110, and the position is along horizontal T and adjacent the One beam 108 is spaced apart and positioned between them.Thus, one or more holes 110 are until all holes 110 can be along second distance D2 extends on horizontal T.

Shielding body 102 may also include for example multiple second body members of at least one second body member, the second body Component can be configured as the second beam 114, the second beam 114 along can parallel to first direction second direction, for example generally along Horizontal T, elongation.Specifically, the second beam 114 can extend along horizontal T between the first adjacent beam 108.One or more Two beams 114 are until all second beams 114 can connect between the first adjacent beam 108 and be connected to the first adjacent beam 108.According to illustrated embodiment, the second beam 114 can be with the general coplanar of the first beam 108 and can be one or more until all Extend between the mutually reply of the first adjacent beam 108, and can be one or more until all the first adjacent beam 108 Connected between mutually tackling.Thus, the second beam 114 can be on signal contact 35 in horizontal T upper offsets, so as to along extending laterally Line is without the second beam 114 and signal contact 35.Similarly, the first beam 108 can on signal contact 35 in horizontal T upper offsets, So as to along the line extended laterally without the first beam 108 and with signal contact 35.In addition, the first beam 108 phase adjacency pair it Between each second beam 114 for extending can be along horizontal T aligned in general.Similarly, each first beam 108 can be along horizontal T substantially Alignment.Although it should also be clear that being connected according to each second beam 114 of illustrated embodiment between the first adjacent beam 108, Two beams 114 can also be continuous across the first beam 108, so that one or more, until it is all, prolong between the first beam 108 Stretch and through one or more, until all, the first beam 108.

Second beam 114 can generally along longitudinal L intervals and be opened so that hole 110 is divided into at least one opening for example multiple first Mouthful 110a, the second opening 110b are, and the 3rd opening 110c.Therefore, the second beam 114 also referred to as separates beam.It should be appreciated that shielding Body 102 can limit multiple second beams 114 between the first adjacent beam 108 as needed, to limit multiple phases as needed It should be open.According to illustrated embodiment, the first opening 110a can limit the first outside opening of the forefront for being positioned along longitudinal L, Second opening 110b can be limited in the second outside opening of the rearmost for being positioned along longitudinal L, and the 3rd opening 110c restrictions Between be open, middle opening be arranged at along longitudinal L first and second opening 110a and 110b between.As needed, this is shielded Body 102 can be defined to the 3rd opening 110c being arranged between the first and second opening 110a and 110b.One or more openings 110a-c until all opening 110a-c can laterally overlapping corresponding signal electrical contacts 35 of A, as illustrated, so as to along side The line extended to A can be by corresponding one in a corresponding signal contact and opening 110a-c.In addition, the institute of the second beam 114 Select some can across signal contact 35 mutually reply, the signal contact 35 mutually tackle selected by the second beam 114 those open That of beginning extension between the first beam 108 to extending.Second beam 114 can by with signal contact 35 laterally A intervals so that second Beam 114 is electrically insulated with signal contact 35.

At least one or more opening 110a-c can be limited up to all opening 110a-c by the periphery of closing, the envelope The periphery closed includes at least a portion of a pair of second beams 114 and a pair of first beams 108.Second beam 114 can limit for example along The opposite external margin 116 at longitudinal L intervals, so as to limit the second size or width W2, the second size or width W2 by along Longitudinal L is defined at least one second beam 114 until between the external margin 116 of all second beams 114.Shielding body 102 is limited Determine second distance D2, second distance D2 by along the longitudinally defined adjacent external margin 116 in the second adjacent beam 114 it Between.Should be appreciated that second distance D2 can accordingly reduce when the second width W2 increases, and when the second width W2 reduces second away from Can accordingly it increase from D2.It should be appreciated that second distance D2 limits corresponding sizes of each opening 110a-c along longitudinal direction, and be open The second distance D2 of one of them of 110a-c may differ from one or more up to all opening 110a-c.

It should be appreciated that the second beam 114 makes the first beam 108 of the first electric connector 22 be electrically connected each other, to be set up between following Common ground path：1) two or more ground connection abutting ends 106 are up to all ground connection abutting ends 106,2) two or more Up to all ground connection installation ends 104, and 3), at least one ground connection abutting end 106 connects individual ground connection installation end 104 up to all Ground abutting end 106 and at least one ground connection installation end 104 are up to all ground connection installation ends 104.When the first and second electrical connections Device 22 and 24 is engaged, and when ground connection abutting end 106 and 66 (with reference to Fig. 4 A) is engaged accordingly, common ground shielding 100 Set up the common ground path extended across the mating interface 30 and 34 of electric connector 22 and 24.Therefore, in the first and second electricity The common electrical grounding path across the first electric connector 22 is set up in common ground shielding 100 before connector 22 and 24 is engaged. After the first and second electric connectors 22 and 24 are engaged, common ground shielding 100 is also set up across mating interface 34, specifically Ground is grounded abutting ends 66 across at least two of the second electric connector 24 until the electrically grounded path of all ground connection abutting ends 66. Therefore, the first and second electric connectors 22 and 24 can limit corresponding first and second grounding path, be electrically connected when first and second When connecing device 22 and 24 and being engaged, first and second grounding path limits that the first and second electric connectors 22 and 24 are public to be connect Ground path.

It should be appreciated that shielding body 102 limits multiple holes 110, hole 110 can extend between the first adjacent beam 108, and It can also extend between the second adjacent beam 114.Although being in general rectangular in the plane endoporus 110 limited by longitudinal L and transverse direction T Shape, it will be appreciated that hole 110 can limit any shape as needed, for example, according to the external margin 112 of the first beam 108 and The geometry of the external margin 116 of two beams 114.Although shielding body 102 is limited in each the first adjacent beam 108 between Fixed four the second beams 114 and three respective openings 110a-c, it will be appreciated that shielding body 102 can include multiple the as needed Two beams 114, to limit multiple respective apertures 110 as needed.In addition, each opening 110a-c is limited and is equal to first apart from D1 and the Two apart from D2 product respective area.It is therefore to be understood that each opening 110a-c area can change, for example, by changing respectively Become the first and second width W1 and W2 of the first beam 108 and the second beam 114, and by changing the number of the second beam 114 with phase The distance along longitudinal L between the second adjacent beam 114 should be changed.It should also be clear that the accumulation area in hole 110, and be therefore open 110a-c accumulation area, limits total open area OA of shielding body 102.Total open area OA of shielding body 102 can increase Big and reduction, such as by change opening 110a-c number and further by changing opening in the manner 110a-c size.It may therefore provide with different open areas, and it is one or more until all opening 110a-c Different area common ground shielding 100 external member.

Have appreciated that when the first and second electric connectors 22 and 24 are engaged, the first and second electric connectors 22 and 24 Laterally A limits mating area 118, and such as mating area 118 can be defined as abutting end 38 and ground connection abutting end 106 extremely Few one or both and at least one for being grounded abutting end 66 and abutting end 50 of the signal electrical contact 44 of the second electric connector 24 Or two (with reference to Fig. 4 A) overlapping region.It should also be clear that when shielding total open area OA increases of body 102, mating area Impedance at 118 also increases.If for example, shielding body 102 is not perforated, and therefore total open area is zero, fitting area Impedance at domain 118 is generally below the expection impedance of electric coupler component 20, so that the impedance at mating area 118 is on being electrically connected Connect the expection impedance mismatch of device assembly 20.

In addition, common ground shielding 100 may be configured such that the first and second electric connectors 22 and 24 when being engaged at least It is one or more until the signal of all opening 110a-c electric connector 24 of overlapped signal contact 35 and second at least in part One or both in contact 44.According to illustrated embodiment, the first opening 110a of common ground shielding 100 completely overlapped can believe At least a portion of number contact 35 and signal contact 44, for example, at abutting end 50, in mating area 118.Common ground is shielded 100 the 3rd opening 110c can, be shown in mating area 118, the signal contact 44 for second electric connector 24 that partly overlaps At least a portion, or can the signal contact 44 of completely overlapped second electric connector 24 of mating area 118 at least a portion. Each opening 110a-c area can be reduced to reduce the crosstalk at mating area 118.For example, according to one embodiment, when When first and second electric connectors 22 and 24 are engaged, each opening 110a-c area is smaller than by electric across first and second The wavelength for the signal that the signal contact 35 and 44 of connector 22 and 24 is transmitted.When the signal transmitted across signal electrical contact 35 and 44 Frequency increase when opening 110a-c area can be reduced.

It should be understood that individual opening 110a-c number and area and total open area OA, which are adjustable to, makes cooperation The expection impedance of impedance substantial match electric coupler component 20 at region 118, and crosstalk is lowered, while allowing public connect Ground shielding 100 is set up across at the mating interface 30 and 34 of the first and second electric connectors 22 and 24 in the manner The common ground path of corresponding earthing component, such as at mating area 118.In other words, hole 110 can limit balance by matching somebody with somebody The impedance in region 118 and the area of crosstalk are closed, wherein crosstalk can relatively be raised with signal frequency (or wavelength).

In addition, the common ground shielding 100 of the first electric connector 22 can be between earth plate 62 corresponding to the second electric connector Every (with reference to Fig. 4 B), for example, in the region being aligned with the signal contact 44 of the second electric connector 24 along horizontal T, to limit Multiple gaps 120, gap 120 limits the first distance along longitudinal L, and the first distance can be substantial access to, or is substantially equivalent to, second away from From D2.Gap 120 further can limit second distance between adjacent ground connection abutting end 66 along horizontal T, and second distance can First extended between the first adjacent beam 108 that 100 are substantially equivalent to shielded in common ground is apart from D1.For example, it should be understood that when The first beam 108 can be aligned with ground connection abutting end 66 along longitudinal L when first and second electric connectors 22 and 24 are engaged.Therefore, Gap 120 can limit corresponding area, be sized to the impedance matching generally maintained across mating area 118 while also dropping Crosstalk at low mating interface 34.For example, the area in each gap 120 is smaller than the signal contact across the second electric connector 24 The wavelength of the signal of 44 transmission.

As described above, shielding body 102 by signal electrical contact 35 in lateral A upper offsets so that shielding body 102 with Signal electrical contact 35 is laterally spaced for example apart from D3 (with reference to Fig. 2 E).In addition, ground connection installation end 104 can be with signal contact 35 Installation end 40 along horizontal T be aligned.Therefore, it is public to connect when being grounded mounting portion 104 and shielding body 102 is integrally formed Ground shielding 100 may include the transitional region 122 extended between shielding body 102 and each ground connection mounting portion 104.Transition region Domain 122 can be along longitudinal L backward and laterally A stretches out towards corresponding common column CL.Being grounded mounting portion 104 can be Position with the installation end 40 of signal contact along horizontal T aligned in general extends back from transitional region 122 along longitudinal L.

As described above, common ground shielding 100 may also include at least one rib 124, such as multiple ribs 124, rib 124 is by shielding Cover body 102 support and from shielding body 102 laterally the outside projections of A to limit abutting end, for example, be grounded abutting end 106.According to illustrated embodiment, at least one is until all rib 124 is from the outside projection of corresponding first beam 108.According to institute Show embodiment, each rib 124, which is molded, makes its protrusion on corresponding first beam 108, and therefore to described corresponding one Individual first beam 108 is integrally formed.Therefore, rib 124 may be additionally referred to as convex portion, although should be appreciated that rib 124 can be alternatively as needed Constructed.Rib 124 can be constructed substantially as described in the rib 74 of the earth plate 62 below with reference to the second electric connector 24, and And can be from the first beam 108 laterally outside distances of projection one of A, when the first and second electric connectors 22 and 24 are engaged, foot With the earthing component 59 with the second electric connector 24, and specifically with being grounded abutting end 66, contact.Therefore, the first electrical connection The ground connection abutting end 106 of device 22 can be limited by projecting outwardly rib 124 from the first beam 108.At least a portion of rib 124 can example Such as it is aligned at body 39 with signal contact 35 along horizontal T.For example, at least a portion of rib 124 can be placed in by signal Between the adjacent Difference signal pair 45 that contact 35 is limited, and therefore replaceable discrete grounding contact.Thus, first is electrically connected Connecing device 22 may include the public affairs of the discrete grounding contact instead of extending between the adjacent Difference signal pair of typical electrical connector Earth shield 100 altogether.

Should be appreciated that the selected performance characteristic of common ground shielding 100 can adjust as needed.For example, opening 110a-c is limited Area can be adjusted as described above, shielding body 102 limit total open area OA can be adjusted as described above, and Signal contact 44 of the body 102 relative to the second electric connector 24 is shielded when the first and second electric connectors 22 and 24 are engaged Position can further be adjusted.For example, shielding body 102 may be disposed at ground connection installation end 104 longitudinal direction behind, or with figure Embodiment described in 2A-E is compared closer to ground connection installation end 104, and this can be with 1) when the first and second electric connectors 22 and 24 phases During cooperation, reduce a part of total open area OA of overlapped signal electrical contact 44 for example at abutting end 50, and 2) when the One and second electric connector 22 and 24 when being engaged, increase is arranged at the gap between common ground shielding 100 and earth plate 62 120 along longitudinal L size.In addition, shielding body 102 may be disposed at ground connection installation end 104 longitudinal direction before, or with Fig. 2A-E Described embodiment is compared further from ground connection installation end 104, and this can be with 1) when the first and second electric connectors 22 and 24 are engaged When, increase a part of total open area OA of overlapped signal electrical contact 44 for example at abutting end 50, and 2) when the first He When second electric connector 22 and 24 is engaged, reduction is arranged at the gap 120 between common ground shielding 100 and earth plate 62 Longitudinal size.

Moreover, with reference now to 3A-D, shielding body 102 and signal electrical contact 35 are by laterally A spacing distances D4.Distance D4 can be arranged as required to size, and be more than according to illustrated embodiment apart from D3 (with reference to Fig. 2 E).For example, common ground is shielded 100 may include multiple dactylozoites 126, and dactylozoite 126 is from shielding body 102 along longitudinal L forward and from shielding body 102 edge Lateral A towards corresponding common column CL to extend.According to illustrated embodiment, dactylozoite 126 extends from the first beam 108.Dactylozoite 126 It can be integrally formed, or can be separated from shielding body 102 so that dactylozoite 126 and shielding body with shielding body 102 as shown in the figure 102 are electrically connected each other when connected device housing 31 is supported.Each dactylozoite 126 can be bifurcated as shown in the figure, or as needed Single solid dactylozoite can be limited.Should be appreciated that ground connection abutting end 106 can be limited by dactylozoite 126 so that dactylozoite 126 by with The earthing component 59 being set to the second electric connector 24 makes electrical contact with.It is grounded the transition region between installation end 104 and shielding body 102 Domain 122 laterally can extend to the depth equal to transitional region 122 so that shielding body 102 is in substantially parallel relationship to common column CL by A Extension.

When the first and second electric connectors 22 and 24 are engaged, dactylozoite 126 can contact earthing component 59, and specifically Ground contacts the earth plate body 64 of the second electric connector 24.Alternatively, dactylozoite 126 may be configured such that first and second are electrically connected Connect the ground connection installation end 68 that the second electric connector 24 is contacted when device 22 and 24 is engaged.It should be appreciated that common ground shielding can also include Rib 124 and dactylozoite 126 as described above.Rib 124 can laterally A be extended laterally to limit substantially etc. from shielding body 202 In dactylozoite 126 and the depth of transitional region 122, so as to contact second when the first and second electric connectors 22 and 24 are engaged The earthing component 59 of electric connector 24, such as at corresponding installation end 66.

Therefore electric coupler component 20 may include the first He for shielding 100 and the restriction of earth plate 62 by common ground respectively Second crosstalk shields that can coordinate.First can coordinate twine crosstalk shields, such as common ground shielding 100, including first touch Head dactylozoite, such as dactylozoite 126, and the second crosstalk shields can limit the second contact dactylozoite, for example, be grounded abutting end 66 The dactylozoite of restriction.When the first and second electric connectors 22 and 24 mate with each other, the first contact dactylozoite, such as dactylozoite 126, can material contact earth plate 62, and the second grounding contact dactylozoite, for example, the finger-like limited by ground connection abutting end 66 Body, can material contact common ground shielding 100.

Alternatively, the depth of rib 124 is smaller than the depth of dactylozoite 126 with when the first and second electric connectors 22 and 24 phases Only have dactylozoite 126 to set up with the earthing component 59 of the second electric connector 24 during cooperation to electrically connect.It should be appreciated that ground connection as needed Abutting end 106 can limit any appropriate depth on lateral A, and body 102 is shielded on signal electrical contact 35 with corresponding adjustment, And therefore common column CL, the offset or dish D4 on lateral A.

It is therefore to be understood that the external member of electric connector 22 is configurable to have different performance characteristics, for example, it is adjusted or It is adjusted on including other identical electric connectors reduction of discrete grounding contact rather than common ground shielding 100 Crosstalk when unlike signal frequency and wavelength, and can further be configured in the operating process of electric connector 22 in difference Impedance level under operate.For example, each of multiple electric connectors 22 may include different number of opening 110a-c, opening 110a-c has different areas, a different total open area OA, and shield body can be relative to signal contact 35 differently Positioning.For example, the lengthwise position of shielding body 102 can be different, and biased on signal contact 35.All these different In configuration, it should be understood that open area, such as by extending through the regions that limit of opening 110a-c of shielding body 102, position Can be different from connector to connector.The position can be along the direction for the common column CL for being in substantially parallel relationship to signal contact, and edge The direction difference of the common column CL generally perpendicular to signal contact.
