Referring now to Fig. 1-2 E, the first electric connector 22 can further comprise at least one conductive common ground shielding 100 for example multiple common ground shieldings 100, common ground shielding 100 are configured to when the first and second electric connectors 22 and 24 Cooperate when matching to the corresponding earthing component 59 of the second connector 24.Therefore, earthing component 59 is configured to and common ground 100 cooperation of shielding, and it is configured to mount to the second substrate 28, it is described more fully below.Common ground shielding 100 can be by appointing What conductive material appropriate is formed, such as metal or conductive lossy material.It is public as understood from the following description Earth shield 100 can establish ground connection electrical connection between the first and second electric connectors 22 and 24 matched.

Common ground shielding 100 may be provided at mating interface 30, and including shielding ontology 102 with holes, shielding is originally Body 102 can be substantitally planar along the plane limited by longitudinal L and transverse direction T when being connected device shell 31 and supporting, and Relative to the respective column CL biasing limited by signal electrical contact 35, so as to shield not Contacting signal probe 35 of ontology 102.First electricity Connector 22 includes from shielding ontology 102 outwardly extending multiple ground connection installation ends 104 along a first direction.It is grounded installation end 104 can with shielding ontology 102 it is integrated or can with shielding ontology 102 separate, so as to when shielding ontology 102 by connector shell Ground connection installation end 104 is electrically connected with the second end for shielding ontology 102 when 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 are 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 lateral T Or setting adjacent with a pair of of installation end 40 of adjacent signal electrical contact 35 is 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 installation interfaces along electric connector 22 32 along common column CL spaced at equal intervals.According to one embodiment, being grounded 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, it is configured according to contact, the first electrical connection Device 22 can limit duplicate G-S-S mode, wherein " G " indicates a ground connection installation end 104 of common ground shielding 100, and One installation end 40 of " S " expression signal electrical contact 35, wherein two adjacent " S " in duplicate G-S-S can indicate difference Signal to 45 signal contact 35 installation end 40.It should be understood that the first row in column CL can be limited from the top nematic CL's of column CL The first contact of the duplicate G-S-S of bottom configures, and the secondary series in the column CL adjacent with the first row in column CL can limit Surely it is different from the second contact configuration of the first contact configuration.For example, the configuration of the second contact can limit the top nematic CL from column CL Bottom duplicate S-S-G.In this way, laterally A column CL can limit duplicate first He across the first electric connector 22 The configuration of second contact (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 as the first contact configuration.

First electric connector 22 further includes multiple ground connection abutting ends 106, ground connection abutting end 106 from shielding ontology 102 along Second direction extends outwardly, and second direction is opposite with the first direction that ground connection installation end 104 extends from shielding ontology 102.Ground connection Abutting end 106 can be integrated with shielding ontology 102 or can be separated from shielding ontology 102, when shielding ontology 102 is by connector Ground connection abutting end 106 is electrically connected with the second end for shielding ontology 102 when shell 31 supports.Being grounded abutting end 106 can be with signal electricity The abutting end 38 of contact 35 is configured to along common column CL aligned in general when the first and second phases of electric connector 22 and 24 The complementary fit end of the earthing component 59 of the second electric connector 24 is electrically connected to when cooperation.

Being grounded abutting end 106 can be substantially collinear along longitudinal L and ground connection installation end 104, so that along the line of longitudinal L extension It can be by a ground connection installation end 104 of a ground connection abutting end 106 and alignment.Ground connection abutting end 106 is arranged at along cross To between a pair of of abutting end 38 of the signal contact 35 of T.Being grounded abutting end 106 can be along the cooperation of lateral T and signal contact 35 38 alignment of end, so that the line extended along lateral T can be by the abutting end 38 of ground connection abutting end 106 and signal contact 35.It is similar Ground, ground connection installation end 104 can be aligned along lateral T with the installation end 40 of signal contact 35, so that can along the line that lateral T extends 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 30 equidistant interval of mating interface of electric connector 22.Correspondingly, ground connection abutting end 106 can be set to 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 ontology 102 is shielded towards the corresponding public of the signal contact 35 being aligned with ground connection installation end 104 and ground connection abutting end 106 Arrange the outside projection of CL.

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

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

Shielding ontology 102 may also include for example multiple second body members of at least one second body member, the second ontology Component can be configured to the second beam 114, the second beam 114 along the second direction that can be parallel to first direction, such as generally along Lateral T, elongation.Specifically, the second beam 114 can extend between the first adjacent beam 108 along lateral T.One or more the 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 108 general coplanar of the first beam and can be one or more until all Extend between the mutually reply of the first adjacent beam 108, and can be in one or more up to all the first adjacent beams 108 Mutually connected between reply.Thus, the second beam 114 can bias on lateral T about signal contact 35, so as to along being laterally extended Line is without the second beam 114 and signal contact 35.Similarly, the first beam 108 can bias on lateral T about signal contact 35, So as to along the line being laterally extended without the first beam 108 and with signal contact 35.In addition, the first beam 108 phase adjacency pair it Between each of extend the second beam 114 can be along lateral T aligned in general.Similarly, each first beam 108 can be along lateral 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, thus in one or more, until it is all, prolong between the first beam 108 One or more is stretched and passes through, until all, the first beam 108.

Second beam 114 can be opened generally along longitudinal interval L with hole 110 is divided at least one opening for example multiple first Mouth 110a, the second opening 110b and third opening 110c.Therefore, the second beam 114 also referred to as separates beam.It should be appreciated that shielding Ontology 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 external opening of the forefront for being positioned along longitudinal L, Second opening 110b can limit the second external opening of the rearmost for being positioned along longitudinal L, and in third opening 110c restriction Between be open, middle opening be set to along longitudinal L first and second opening 110a and 110b between.As needed, this is shielded Body 102 can be limited to the third being set between the first and second opening 110a and 110b opening 110c.One or more opening 110a-c is until all opening 110a-c laterally can be overlapped corresponding signal electrical contact 35 by A, as shown, 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 it is some can be across the mutually reply of signal contact 35, the signal contact 35 is mutually coped with selected by the second beam 114 those and is opened That of beginning extension extends between the first beam 108.Second beam 114 can by with signal contact 35 laterally the interval A so that second Beam 114 is electrically insulated with signal contact 35.

At least one or more opening 110a-c is until all opening 110a-c can pass through closed periphery restriction, the envelope The periphery closed includes at least part of the second beam of a pair 114 and a pair of first beam 108.Second beam 114 can limit for example along The opposite external margin 116 at longitudinal interval L, thus 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.Ontology 102 is shielded to limit 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 It can be increased accordingly from D2.It should be appreciated that second distance D2 limits each opening 110a-c along longitudinal corresponding size, 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 establish 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 a 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 matches, and when being grounded abutting end 106 and 66 (refer to Fig. 4 A) accordingly and matching, common ground shielding 100 Establish 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 established in common ground shielding 100 before connector 22 and 24 matches. After the first and second electric connectors 22 and 24 match, common ground shielding 100 is also set up across mating interface 34, specifically Ground is grounded abutting ends 66 up to the electrically grounded path of all ground connection abutting ends 66 across at least two of the second electric connector 24. 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 matching, first and second grounding path limits that the first and second electric connectors 22 and 24 are public to be connect Ground path.

Should be appreciated that shielding ontology 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 in the plane inner hole 110 limited by longitudinal L and transverse direction T in general rectangular 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 the limiting between in each the first adjacent beam 108 of ontology 102 Fixed four the second beams 114 and three corresponding opening 110a-c, it will be appreciated that shielding ontology 102 can include multiple the as needed Two beams 114, to limit multiple corresponding apertures 110 as needed.In addition, each opening 110a-c, which is limited, is equal to first distance D1 and the The respective area of the product of two distance D2.It is therefore to be understood that the area of each opening 110a-c is changeable, 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 the number by changing the second beam 114 with phase The distance between the second adjacent beam 114 along longitudinal L should be changed.It should also be clear that the accumulation area in hole 110, and be therefore open The accumulation area of 110a-c limits total open area OA of shielding ontology 102.Total open area OA of shielding ontology 102 can increase Big and reduction, such as by the number of change opening 110a-c and further by changing opening in the manner The size of 110a-c.It may therefore provide there is different open areas, and one or more until all opening 110a-c Different area common ground shielding 100 external member.

It has appreciated that when the first and second electric connectors 22 and 24 match, the first and second electric connectors 22 and 24 Laterally A limits mating area 118, such as mating area 118 can be defined as abutting end 38 and ground connection abutting end 106 extremely At least one for being grounded abutting end 66 and abutting end 50 of the signal electrical contact 44 of few one or both and the second electric connector 24 Or the region of two (referring to Fig. 4 A) overlappings.It should also be clear that when the total open area OA for shielding ontology 102 increases, mating area Impedance at 118 also increases.For example, if shielding ontology 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 about being electrically connected Connect the expection impedance mismatch of device assembly 20.

In addition, common ground shielding 100 may be configured such that when the first and second electric connectors 22 and 24 match at least It is one or more until all opening 110a-c at least partly overlapped signal contact 35 and the second electric connector 24 signal 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 part of number contact 35 and signal contact 44, for example, at abutting end 50, in mating area 118.Common ground shielding 100 third opening 110c can, as shown in the figure in mating area 118, the signal contact 44 for second electric connector 24 that partly overlaps At least part, or can be at least part of the signal contact 44 of completely overlapped second electric connector 24 of mating area 118. The area of each opening 110a-c 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 match, the area of each opening 110a-c 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 transmits.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 the number and area of individual opening 110a-c and total open area OA, which are adjustable to, to be made to cooperate 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 established in the manner across at the mating interface 30 and 34 of the first and second electric connectors 22 and 24 The common ground path of corresponding earthing component, such as at mating area 118.In other words, hole 110 can limit balance by matching The impedance in region 118 and the area of crosstalk are closed, wherein crosstalk can relatively be increased 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 (referring to Fig. 4 B), for example, in the region being aligned with the signal contact 44 of the second electric connector 24 along lateral T, to limit Multiple gaps 120, gap 120 limit first distance along longitudinal L, and first distance can be substantial access to, or are substantially equivalent to, second away from From D2.Gap 120 further can limit second distance along lateral T between adjacent ground connection abutting end 66, and second distance can The first distance D1 substantially equivalent to extended between the first adjacent beam 108 of common ground shielding 100.Such as, 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 match.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 ontology 102 biased on lateral A about signal electrical contact 35 so that shielding ontology 102 with Signal electrical contact 35 is laterally spaced such as distance D3 (with reference to Fig. 2 E).In addition, ground connection installation end 104 can be with signal contact 35 Installation end 40 along lateral T be aligned.Therefore, public to connect when being grounded installation section 104 and shielding ontology 102 is integrally formed Ground shielding 100 may include the transitional region 122 extended between shielding ontology 102 and each ground connection installation section 104.Transition region Domain 122 can A extends outwardly towards corresponding common column CL backward and laterally along longitudinal L.Being grounded installation section 104 can be It extends back from transitional region 122 along longitudinal L with the installation end 40 of signal contact along the position of lateral T aligned in general.

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 It covers the support of ontology 102 and laterally the outside projection of A is to limit abutting end from shielding ontology 102, such as ground connection abutting end 106.According to illustrated embodiment, at least one until all rib 124 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 A first beam 108 is integrally formed.Therefore, rib 124 may be additionally referred to as protrusion, while it will be appreciated that rib 124 can optionally as needed It is 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 one distance of projection of A, when the first and second electric connectors 22 and 24 match, foot With the earthing component 59 with the second electric connector 24, and specifically contacted with ground connection abutting end 66.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 part of rib 124 can example It is aligned with signal contact 35 along lateral T such as at body part 39.For example, at least part of rib 124 can be placed in by signal Between the adjacent Difference signal pair 45 that contact 35 limits, and therefore replaceable discrete grounding contact.Thus, first is electrically connected Connect the public affairs that device 22 may include the discrete grounding contact instead of extending between the adjacent Difference signal pair of typical electrical connector Earth shield 100 altogether.

It 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 ontology 102 limit total open area OA can be adjusted as described above, and Signal contact 44 of the ontology 102 relative to the second electric connector 24 is shielded when the first and second electric connectors 22 and 24 match Position can further progress adjustment.For example, shielding ontology 102 may be disposed at ground connection installation end 104 it is longitudinal below, or with figure 2A-E the embodiment described is compared closer to ground connection installation end 104, this can be 1) when the first and second phases of electric connector 22 and 24 When cooperation, reduce for example at abutting end 50 a part of total open area OA of overlapped signal electrical contact 44 and 2) when the One and second electric connector 22 and 24 when matching, increase the gap being set between common ground shielding 100 and earth plate 62 120 along longitudinal L size.In addition, shielding ontology 102 may be disposed at longitudinal front of ground connection installation end 104, or with Fig. 2A-E The embodiment described is compared further from ground connection installation end 104, this can be 1) when the first and second electric connectors 22 and 24 match When, increase a part of total open area OA of overlapped signal electrical contact 44 and 2) when the first He for example at abutting end 50 When second electric connector 22 and 24 matches, reduce the gap 120 being set between common ground shielding 100 and earth plate 62 Longitudinal size.

Moreover, shielding ontology 102 and signal electrical contact 35 by laterally A spacing distance D4 referring now to 3A-D.Distance Size can be set as needed in D4, and is greater than distance D3 (referring to Fig. 2 E) according to illustrated embodiment.For example, common ground shields 100 may include multiple dactylozoites 126, and dactylozoite 126 is from shielding ontology 102 along longitudinal L forward and from shielding 102 edge of ontology Lateral A extend towards corresponding common column CL.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 ontology 102 so that dactylozoite 126 and shielding ontology with shielding ontology 102 as shown in the figure 102 are electrically connected each other when connected device shell 31 supports.Each dactylozoite 126 as shown in the figure can be bifurcated, or as needed Single solid dactylozoite can be limited.It should be appreciated that ground connection abutting end 106 can be limited by dactylozoite 126, so that dactylozoite 126 is matched It is set to and is in electrical contact with the earthing component 59 of the second electric connector 24.It is grounded installation end 104 and shields the transition region between ontology 102 Domain 122 laterally can extend to the depth equal to transitional region 122 so that shielding ontology 102 is in substantially parallel relationship to common column CL by A Extend.
