Detailed Description
Referring to fig. 1, a cable connector system 10 includes a cable connector 100 and a complementary cable connector 200. For ease of discussion, cable connectors 100 and 200 are referred to as first and second cable connectors, respectively. However, it should be understood that the cable connectors 100 and 200 may alternatively be referred to simply as cable connectors, or as male and female cable connectors, respectively, or as plug and receptacle connectors, respectively. Or as the second cable connector and the first cable connector, respectively. The first cable connector 100 and the second cable connector 200 are configured to dock with each other such that the first cable connector 100 and the second cable connector 200 are in electrical communication with each other. In one example, first cable connector 100 may have a clip (clip)101, clip 101 being configured to fixedly attach first cable connector 100 to second cable connector 200 when first cable connector 100 and second cable connector 200 are mated with each other. The catch 101 may comprise at least one tooth 101a, such as a pair of teeth 101a, each configured to engage a corresponding recess 213c of the mating interface of the second cable connector 200. It should be understood that other types of fasteners than the clasps 101 may be used to fixedly attach the first cable connector 100 to the second cable connector 200.
The first cable connector 100 may be configured to be attached to a first end of the at least one first cable 300 such that the first cable connector 100 is in electrical communication with the at least one first cable 300. The second end of the first electrical cable 106 can be configured to be attached to a complementary electrical component (not shown), such as another suitable cable connector. For example, the complementary electrical component can be any suitable cable connector, such as the CPI cable connector described in PCT application number PCT/US2019/55139 filed on 8/10/2019, the teachings of which are incorporated herein by reference as if fully set forth herein, or a suitable connector manufactured by Samtec inc. (santai corporation), such as a novara cable connector, ACCELERATE cable connector, or a direct connect connector described in U.S. patent publication No. 2019/0267732 published on 29/8/2019, the teachings of U.S. patent publication No. 2019/0267732 being incorporated herein by reference as if fully set forth herein. Thus, the at least one first electrical cable 300 can be configured to place the first cable connector 100 and the complementary electrical component in electrical communication with each other.
The second cable connector 200 may be configured to be attached to a first end of the at least one second cable 400 such that the second cable connector 200 is in electrical communication with the at least one second cable 400. A second end of the second electrical cable 400 can be configured to be attached to a second complementary electrical component (e.g., shown in figure 27), such as another suitable cable connector. For example, the second complementary electrical component can be any suitable cable connector, such as a CPI cable connector, for example, a cable connector described in PCT application number PCT/US2019/55139 filed on 8.10.2019, and the second complementary electrical component can also be a suitable connector manufactured by Samtec inc, such as a NOVARAY cable connector, ACCELERATE cable connector, or a direct connector described in U.S. patent publication number 2019/0267732 published on 29.8.2019. The second complementary electrical component can be disposed adjacent to the ASIC or the die package substrate. Thus, the at least one second electrical cable 400 may be configured to place the second cable connector 200 and the second complementary electrical component in electrical communication with each other. Thus, when the first cable connector 100 and the second cable connector 200 are mated, an electrically conductive path may be provided between the first complementary electrical component and the second complementary electrical component through the first cable connector 100 and the second cable connector 200, such as an electrically conductive path from at least one of the first complementary electrical component and the second complementary electrical component to the other of the first complementary electronic component and the second complementary electronic component.
Referring to fig. 2 and 3A, the first electrical connector 100 includes a mating end 102 and a mounting end 104, the mounting end 104 being spaced apart from the mating end 102. The mating end 102 is configured to mate with the second electrical connector 200 along a mating direction MA1And (6) butting. Thus, the second electrical connector 200 is configured to mate with the mating end 102 in the mating direction MA2Butt joint in a butt joint direction MA2And the butt joint direction MA1The opposite is true. For ease of discussion, the docking direction M will be describedA1And MA2Referred to as first docking direction and second docking direction, respectively. However, it should be understood that the docking direction MA1And a docking direction MA2May alternatively be referred to simply asAnd (4) butting direction. The mounting end 104 is configured to mount to at least one cable 300 (shown in fig. 1). The mating end 102 may be spaced from the mounting end 104 along an axis along a first mating direction MA1Extending such that the first electrical connector 100 forms a vertical connector. In an alternative example, the mating end 102 and the mounting end 104 may be angularly offset from each other such that the first electrical connector 100 forms an angled connector, such as a right angle connector.
The electrical connector 100 comprises a first lateral side 106 and a second lateral side 108, the first lateral side 106 and the second lateral side 108 being perpendicular to the first mating direction MA1Are offset from each other. The electrical connector 100 includes a first transverse end 110 and a second transverse end 112, the first transverse end 110 and the second transverse end 112 are perpendicular to the first mating direction MA1And a transverse direction T of the lateral direction a are offset from each other. In one example, the electrical connector 100 is along a first mating direction MA1May be elongated from the first mounting end 104 to the first mating end 102. For example, the electrical connector 100 may have a first mating direction MA1Is greater than the dimension of the electrical connector 100 in the lateral direction a and the dimension of the electrical connector 100 in the transverse direction T. However, it should be understood that in alternative examples, the electrical connector 100 need not be elongated in the longitudinal direction L.
The electrical connector 100 includes a connector housing 114 and a plurality of electrical contacts 116 supported by the connector housing 114. The connector housing 114 may be formed of a dielectric material or an electrically insulating material. The connector housing 114 may have a housing body 115. The housing body 115 may define a cavity 117 therein. The cavity 117 may be configured to receive a first end of the at least one cable 300 when the at least one cable 300 is attached to the electrical contact 116. The housing body 115 of the housing 114 may have any suitable shape. For example, the housing body 115 may have a first lateral sidewall 115a and a second lateral sidewall 115b, the first lateral sidewall 115a and the second lateral sidewall 115b being offset from each other along the lateral direction a to define a cavity 117 between the first lateral sidewall 115a and the second lateral sidewall 115 b. The housing body 115 may have a first transverse end wall 115c and a second transverse end wall 115d, the first and second transverse end walls 115c, 115d being offset from one another along the transverse direction T to define a cavity 117 between the first and second transverse end walls 115c, 115 d.
The housing body 115 may have a first body portion 115e and a second body portion 115f, the first body portion 115e and the second body portion 115f being capable of coupling with each other to define a cavity 117 between the first body portion 115e and the second body portion 115 f. The first and second body portions 115e and 115f may include first and second transverse end walls 115c and 115d, respectively. For example, one of the first body portion 115e and the second body portion 115f may be formed as a cap for the other of the first body portion 115e and the second body portion 115 f. Additionally or alternatively, the first and second body portions 115e, 115f may be formed as first and second halves of a clamshell (clamshell) housing. In other examples, the housing body 115 may be defined as a unitary body portion, or the housing body 115 may include other portions in addition to the first and second coupleable body portions 115e and 115 f.
The first and second lateral side walls 115a, 115b may be along the first butt direction M compared to the first and second lateral end walls 115c, 115dA1Further extending. Accordingly, the first and second lateral sidewalls 115a and 115b may be along the first butting direction MA1And projects beyond the first transverse end wall 115c and the second transverse end wall 115 d. In one example, the first and second lateral sidewalls 115a and 115b may be along the first docking direction MA1At least extending up to the electrical contact 116 or beyond the electrical contact 116. Thus, the first and second lateral sidewalls 115a and 115b may provide protection for the electrical contacts 116. The first lateral sidewall 115a and the second lateral sidewall 115b at the docking end 102 may be substantially flat along a plane along the first docking direction MA1And a transverse direction T. The first and second lateral sidewalls 115a and 115b may have a dimension in the lateral direction a that is less than a dimension in the transverse direction T of the first and second sidewalls 115a and 115 b. It should be understood that the first lateral sidewall 115a and the second lateral sidewall 115aThe lateral side wall 115b may have another suitable shape.
The connector housing 114 may include an inner housing body 118, the inner housing body 118 configured to support at least a portion of the electrical contacts 116, such as supporting the mounting ends of the electrical contacts 116. The inner housing body 118 may be received within the cavity 117 of the outer body portion 115. Alternatively, the inner housing body 115 and the outer housing body 118 may be integrated with each other such that the connector housing 114 has a single housing body. The first and second lateral sidewalls 115a and 115b may be along the first docking direction MA1At least extending up to the inner housing body 118 or beyond the inner housing body 118.
Referring to fig. 4A, fig. 4A illustrates a mating interface of the first electrical connector 100 of fig. 1. The housing 114 is configured to support the electrical contacts 116 such that the electrical contacts 116 are arranged in at least one row, the at least one row extending in the lateral direction a. For example, the at least one row may include a plurality of rows spaced apart from each other along the transverse direction T. For example, the plurality of rows may include, for example, four rows as shown in fig. 4A. In alternative examples, the plurality of rows may include two rows such as shown in fig. 10, six rows, eight rows such as shown in fig. 11, or more than eight rows. The electrical contacts 116 in each row may be spaced apart from each other along the lateral direction a. The rows may be parallel to each other. Each row may be a linear array of electrical contacts 116. Each linear array may extend in the lateral direction a or may extend in another suitable direction.
Each row of electrical contacts 116 includes a plurality of signal contacts 120 and a plurality of ground contacts 122. The signal contacts 120 in each row may be arranged in pairs. Each pair of signal contacts 120 may define a differential signal pair. The signal contacts 120 in each pair may be arranged edge-to-edge. The signal contacts 120 in each pair may be spaced apart from each other in the lateral direction a by a distance d1. Distance d1Can be measured from the center of one signal contact 120 of a pair of signal contacts to the center of the other signal contact 120 of the pair of signal contacts in the lateral direction a. In one example, the distance d1And may be 0.68 mm + -0.05 mm. Additionally or alternatively, the signal contacts 120 in each pair may be spaced apart from each other along the lateral direction a by a distance d11(shown in FIG. 4B), where the distance d11Measured from the innermost edge of one signal contact 120 of the pair to the innermost edge of the other signal contact 120 of the pair. In one example, the distance d11And may be 0.38 mm + -0.05 mm.
The pairs of signal contacts 120 may be spaced apart from each other in the lateral direction a by a distance d2Distance d2Greater than the distance d1. Distance d2Can be measured from a midpoint between two of the pair of signal contacts 120 to a midpoint between two of the adjacent pair of signal contacts 120 in the lateral direction a. E.g. distance d2And may be 2.90 mm ± 0.05 mm.
The plurality of ground contacts 122 in each row includes at least one ground contact 122 between adjacent pairs of signal contacts 120. The plurality of ground contacts may further include an outermost ground contact 123 disposed at an outermost end of each row of contacts, or a pair of outermost ground contacts 123 disposed at an outermost end of each row of contacts. Each pair of signal contacts 120 may be disposed between adjacent ground contacts 122 and 123. As will be described in further detail below, the plurality of ground contacts 122 and 123 in each row may be interconnected by a ground plate 134 (such as shown in fig. 6 and 8A). Each ground contact 122 of the at least one ground contact 122 may comprise a single wider ground contact as shown or two or more ground contacts spaced apart from each other along the lateral direction a. Each ground contact 122 of the at least one ground contact 122 may be spaced apart from an adjacent at least one ground contact 122 by a distance d3. Distance d3May be measured from the center of at least one ground contact 122 to the center of an adjacent at least one ground contact 122 along the lateral direction a. In one example, the distance d3And may be 2.90 mm ± 0.05 mm.
A pair of signal contacts 120 may be spaced apart from an adjacent ground contact 122 by a distance d in the lateral direction a12(as shown in fig. 4B). Distance d12Can be selected from one signal contact 1 of the pair of signal contacts 120The innermost edge of 20 is measured in the lateral direction a to the innermost edge of the adjacent ground contact. In one example, the distance d12And may be 0.50 mm ± 0.05 mm. Additionally or alternatively, a pair of signal contacts 120 may be spaced apart from an adjacent ground contact 123 by a distance d in the lateral direction a13(shown in FIG. 4B), wherein the distance d13Measured from the center of the nearest signal contact 120 (i.e., closest to the ground contact 123) of the pair of signal contacts 120 to the center of the adjacent ground contact 123. In one example, the distance d12And may be 0.78 mm + -0.05 mm.
The electrical contacts 116 arranged in a row may include a mutual spacing distance d4First row R of1And a second row R2. Distance d4Can be selected from the first row R1As shown in fig. 6 and 8A, to a second row R in a transverse direction T2To the ground plane 134. In one example, the distance d4May be 3.15 mm ± 0.05 mm. In other words, the first and second rows may be spaced apart at a row spacing of 3.15 millimeters ± 0.05 millimeters.

Referring to fig. 4A, 5A, and 5B, the electrical connector 100 may optionally include a body 126, the body 126 tuned to absorb a magnetic field of a certain frequency or a certain range of frequencies. For example, the body 126 may have material properties tuned to absorb a magnetic field substantially at the operating frequency of the first electrical connector 100. The word "substantially" with respect to frequency includes frequencies described herein as well as frequencies within 5GHz above and below the frequency (+/-5 GHz). Of course, it should be understood that the body 126 may be configured to attenuate other frequencies as desired. For example, the body 126 may be a broadband absorber. The body 126 may be tuned to attenuate frequency bands at frequencies wider than 1GHz, wider than 10GHz, wider than 20GHz, wider than 30GHz, wider than 40GHz, wider than 50GHz, wider than 60GHz, wider than 70GHz, wider than 80GHz, wider than 90GHz, or wider than 100 GHz.
The body 126 may include a substrate or plate formed of a conductive or non-conductive material. The substrate or plate may act as a shield. The body 126 may include a lossy material or a metamaterial. The substrate or plate may be embedded or otherwise covered by a lossy material or metamaterial. The body 126 may be isolated from ground such that the body 126 is not electrically coupled to ground, wherein the body 126 includes a substrate or plate and/or a lossy material or metamaterial. The lossy material or metamaterial may be magnetically absorptive. In one example, the lossy material or metamaterial may be electrically conductive. For example, the conductivity of the lossy material or metamaterial may be greater than 1 siemens/meter up to about 6.1 x 107Siemens per meter. Alternatively, the lossy material or metamaterial may be non-conductive. For example, the conductivity of the lossy material or metamaterial can range from 1 siemens/m up to 1X 10-17Siemens per meter. Without being bound by theory, it is believed that the lossy material or metamaterial can improve signal integrity relative to a comparable design in which the substrate or board or an ungrounded substrate or board is not embedded or covered by the lossy material or metamaterial. The connector of the present disclosure can meet the 32 gigabit/second PCIE Express Gen 5 standard without the body 126 or can be compatible with 56 gigabit/second NRZ or 112 gigabit/second PAM4 when implemented with the body 126. Without being bound by theory, it is believed that,it is believed that the body 126 may produce lower crosstalk at higher frequencies.
In one example, as shown, the inner housing body 118 can define an opening 118e, the opening 118e extending into the inner housing body 118 in an opposite direction, wherein the opposite direction is opposite the first mating direction MA1Conversely, the opening 118e is configured to receive the body 126. The openings 118e may extend through the inner housing body 118 in opposite directions. Alternatively or additionally, the connector housing 114 may include a body 126, such as the inner housing body 118, of the connector housing 114. Specifically, the connector housing 114 may include a body 126 carried by the inner housing body 118. Specifically, the body 126 may be embedded in the inner housing body 118. Alternatively or additionally, the body 126 may be disposed on an outer surface of the connector housing 114.
The bodies 126 may be arranged in a first row R1Electrical contacts 116 and a second row R2Between the electrical contacts 116. The body 126 may be elongated in the lateral direction a. Accordingly, a dimension of the body 126 in the lateral direction a may be greater than a dimension of the body 126 in the transverse direction T. The body 126 may extend along the centerline CL in the lateral direction a. As shown in fig. 5A, the body 126 may have a transverse direction a and a mating direction MA1A substantially flat body. The body 126 is along the butt joint direction MA1May be greater than the dimension of the body 126 in the transverse direction T. The body 126 may have a generally rectangular front or insertion end 126 a. However, it should be understood that the front or insertion end may have another suitable shape. For example, fig. 5B shows that the leading or insertion end 126a may be chamfered (chamferred). Chamfering the front or insertion end 126a may make it easier to insert the body 126 into the inner housing body 118.
Referring now to fig. 3A and 5A, one example of a method of securing at least one cable 300 to the mounting end 104 of the electrical connector 100 will be described. The at least one cable 300 may include at least one jacket 302 and a plurality of smaller cables 304 supported within the jacket 302, the jacket 302 being, for example, a metal braided jacket. It should be noted that portions of the plurality of smaller cables 304 between the inner housing body 118 and the sheath 300 are hidden for ease of illustration. In one example, the smaller cable 304 may comprise a two-wire cable, such as a twinaxial cable (also referred to as a twisted pair cable). In one example, each twinaxial cable may be a 28-30 American Wire Gauge (AWG) twisted pair cable. The smaller cables 304 may extend out of one end of the sheath 302 and be divided into a plurality of rows, each row corresponding to a row of electrical contacts 116. As shown in fig. 6, each two-wire cable 304 can include a pair of wires electrically coupled to a pair of signal contacts 120 such that each wire in the two-wire cable 304 is electrically coupled to a different one of the pair of signal contacts 120. Additionally or alternatively, the smaller cable 304 may comprise a single wire containing cable, such as a coaxial cable. In one example, the coaxial cable may be a 34AWG coaxial cable. In such examples, each single-wire cable 304 may be electrically coupled to a different signal contact 120.
The first electrical connector 100 may include at least one strain relief 128, the at least one strain relief 128 attached to the corresponding row of smaller cables 304. For example, the first electrical connector 100 may include strain relief 128 for each row of smaller cables 304 to support a row of cables 304 in the strain relief 128. Each strain relief 128 may be overmolded to a row of cables 304 or attached to a row of cables in another suitable manner. The strain relief 128 may be spaced from the inner shell body 118 in an opposite direction from the first mating direction MA1And reversing. Each strain relief 128 may be configured to be received in the cavity 117 of the housing 114 such that the strain relief 128 is aligned with the mating direction MA1And the opposite direction of translation, is fixedly coupled to the housing 114. Accordingly, each strain relief 128 may help relieve strain so that tension applied to cable 300 is transferred to housing 114. This may reduce or limit the force applied to the connection between the smaller cable 304 and the corresponding signal contact 120 of the smaller cable 304. Each strain relief 128 may also arrange a collection of smaller cables 304 in a row.
Referring briefly to fig. 5C and 5D, one example of a method of securing the strain relief 128 in the cavity 117 of the housing 114 is shown. The connector 100 may include at least one protrusion 131, such as a plurality of protrusions 131, at least one protrusion 131 extending from one of the first and second lateral sidewalls 115a, 115b into the cavity 117 of the housing 114. In some examples, each protrusion 131 may have a pointed shape, such as a triangle. Each protrusion 131 is configured to engage one side of at least one strain relief 128 when the strain relief 135 is disposed in the cavity 117. Connector 100 may include a wedge 135, wedge 135 being configured to be received between: (i) the other of the first and second lateral sidewalls 115a and 115b (i.e., on the side opposite the at least one protrusion 131) and (ii) a side of the at least one strain relief 128. In one example, wedge 135 may have a plate-like shape. Optionally, the wedge 135 may include a plurality of protrusions 137, the plurality of protrusions 137 extending inwardly to engage one side of the at least one strain relief 128. When wedge 135 is inserted within cavity 117 between (i) the other of first and second lateral sidewalls 115a and 115b and (ii) the at least one strain relief 128, wedge 135 applies a biasing force to the at least one strain relief 128 that presses the at least one strain relief 128 against the at least one protrusion 131 to fix the position of the at least one strain relief 128 within cavity 117.
Referring to fig. 6 and 7, each row of electrical contacts 116 may include a lead frame 138 (otherwise referred to as an interposer assembly). Each leadframe 138 may include a dielectric or electrically insulative interposer 140 and a row of signal contacts 120 supported by the interposer 140. The row of signal contacts 120 may be overmolded by the body 140. Alternatively, the row of signal contacts 120 may be plugged (pinned) into the interposer 140. Each signal contact 120 may be formed of a conductive metal.
Each signal contact 120 has a signal mounting end 120a and a signal mating end 120b, the signal mating end 120b being opposite the signal mounting end 120 a. The wires 304a of each smaller cable 304 may be soldered or otherwise electrically coupled to each signal mounting end 120 a. Each signal contact 120 has a first signal edge 120c and a second signal edge 120d opposite each other along the lateral direction a. Each signalThe contact 120 has a first signal broadside 120e and a second signal broadside 120f that are opposite each other along the transverse direction T. The contacts 120 can have a width in the lateral direction a across the broadsides 120e and 120f, a thickness in the lateral direction T across the edges 120c and 120d, and a mating direction MA1Length of (d). The width may be greater than the thickness. Further, the length may be greater than the width and thickness. Thus, each signal contact 120 can be elongated as it extends from its signal mounting end 120a to its signal mating end 120 b.
The signal mating end 120b of each signal contact 120 may include a contact beam 120 g. The contact beam 120g may be configured as a flexible beam having a curvature, such as an arc.

The contact beam 120g can include a beam body 120h and a tip 120j extending from the beam body 210 h. The beam body 120h can extend in a direction away from the signal mounting end 120a, and the tip 120j can extend from the beam body 120h in a direction angularly offset from the beam body 120h, such as in the mating direction MA1And a direction angularly offset from the transverse direction T. The beam body 120h and the tip 120j may abut one another at the bend 120 k.
Referring to fig. 6, 8A, and 8B, each row of signal contacts 116 may include a ground conductor 133, the ground conductor 133 including a ground plate 134 and a plurality of ground contacts 122 and 123. The ground plate 134 and each of the ground contacts 122, 123 may be formed of a conductive metal. Each ground plate 134 has a ground mounting end 134a and a ground mating end 134b, the ground mating end 134b being along the first mating direction MA1Opposite the ground mounting end 134 a. Each ground plate 134 has a first ground edge 134c and a second ground edge 134d opposite each other in the lateral direction a. Each ground plate 134 has a first ground broadside 134e and a second ground broadside 134f that oppose each other along the transverse direction T. Each ground plate 134 may have a width in the lateral direction a across the broadsides 134e and 134f, a thickness in the lateral direction T across the edges 134c and 134d, and a mating direction MA1Length of (d). Length ofMay be greater than the thickness. Further, the width may be greater than the length and thickness. Accordingly, each ground plate 134 may be elongated as it extends from its first ground edge 134c to its second ground edge 134 d. Each ground plate 134 may be in the lateral direction a and the first mating direction MA1The extended plane has a substantially flat shape.
Each of the ground contacts 122 and 123 may be butted in a direction M from a ground butting end 134b of the ground plate 134A1And (4) extending. However, it should be understood that in alternative examples, each of the ground contacts 122 and 123 need not extend from the ground plate 134, but may be defined on a surface of the ground plate 134. In one example, each of the ground contacts 122 and 123 can be integral with the ground plate 134. Each ground contact 122 and 123 may define a tab (tab) or a ground contact beam. Each ground contact beam may be configured to have a curved, flexible beam, the curve such as being arcuate. Curved structures as described herein refer to curved shapes that may be manufactured by, for example, bending ends or by stamping a curved shape or by any other suitable manufacturing process. Each ground contact beam may include a beam body 122h, a beam body 123h, and a tip 122j, 123j extending from the beam bodies 122h, 123 h. The beam bodies 122h, 123h may extend in a direction away from the ground plate 134, and the tips 122j, 123j may extend from the beam bodies 122h, 123h in a direction angularly offset from the beam bodies 122h, 123h, such as in a direction M that is aligned with the mating directionA1And a direction angularly offset from the transverse direction T. Beam body 122h and tip 122j may abut one another at bend 122k, and beam body 123h and tip 123j may abut one another at bend 123 k.
The ground plate 134 can include a plurality of engagement features 139 that are configured to engage the cable 304. In some examples, the engagement feature 139 can include a pair of tabs for each cable 304, where the pair of tabs are received on opposite sides of the cable 304. As shown in fig. 8A, a pair of engagement features 139 can define a cradle (cradle) having a recess configured to support one cable 304 therein. In some casesIn an example, the ground plate 134 may include a stiffening rib 141, the stiffening rib 141 configured to strengthen the ground plate 134 so as to limit bending of the ground plate 134, although examples of the present disclosure are not limited to having the rib 141. The ribs 141 may be elongated in the lateral direction a. Thus, the ribs 141 may have a length in the lateral direction a that is greater than the length of the ribs 141 in the mating direction MA1Is measured. The ribs 141 may limit bending along an axis that is along the mating direction MA1Extending, the bending will cause the first and second grounding edges 134c, 134d to move toward each other. The ribs 141 may be stamped or otherwise formed in the ground plate 134. As shown in fig. 8B, the ribs 141 may have a first side and a second side that are spaced apart from each other along the transverse direction T. The first side may define a recess that may receive a portion of the insulative insert 140 of the leadframe 138 therein. The second side of the rib 141 may define a protrusion extending into the insulating insert 140. The interposer and/or the recess may help retain the ground plate 134 within the interposer 140.
Referring briefly to fig. 4A, the electrical contacts 116 of each row may be aligned with corresponding electrical contacts of an adjacent row along the transverse direction T. For example, each pair of signal contacts 120 in a row may be aligned in the transverse direction T with a pair of signal contacts 120 in each adjacent row. Thus, it can be said that the signal contact pairs are arranged in a column of signal contacts. Similarly, each ground contact 122 in a row may be aligned with a ground contact 122, 123 in each adjacent row along the transverse direction T. Therefore, it can be said that the ground contacts are arranged in a column of the ground contacts. Thus, the signal contacts 120 and ground contacts 122 in each row are not staggered with respect to the signal contacts 120 and ground contacts 122 in each adjacent row, but are aligned with those contacts. It should be understood that in alternative examples, the signal contacts 120 and ground contacts 122 in one row may be staggered with respect to the signal contacts 120 and ground contacts 122 in an adjacent row.
The electrical contacts 116 in each row may be arranged edge-to-edge along the lateral direction a. The electrical contact disposed on the first side of the centerline CL may have a tip 120j, a tip 122j, a tip 123j, the tip 120j, the tip 122j, the tip 123j extending or bending away from the centerline CL in a first direction. The electrical contact disposed on the second side of the centerline CL may have a tip 120j, a tip 122j, and a tip 123j, the tip 120j, the tip 122j, and the tip 123j extending or bending away from the centerline CL in a second direction, the second direction being opposite the first direction. In some examples, the electrical contacts disposed on the second side of the centerline CL may mirror the electrical contacts disposed on the first side of the centerline CL.

The plurality of arms 136b may include first and second arms 136b, the first and second arms 136b being spaced apart from each other along the lateral direction a. The base 136a is configured to be disposed on a first side (e.g., 134f) of the ground conductor 133, and the arms 136b are configured to extend through respective apertures 143 of the ground conductor 133 and engage the cap 132 on a second side (e.g., 134e) of the ground conductor 133. The arms 136b may define a catch configured to hold the cap 132 over the signal mounting end 120 and the ground conductor 133.
The first electrical connector 100 may optionally include strain relief 130 for each row, the strain relief 130 attached to the smaller cable 304. Each strain relief 130 may be overmolded to a row of cables 304 or attached to a row of cables in another suitable manner. The strain relief 130 may be configured to be secured to the cover 132. The strain relief 130 may be formed of an electromagnetic interference absorbing material. The strain relief 130 may be configured to provide strain relief for the smaller cable 304 to prevent the cable 304 from disconnecting from the signal contact 120.
Referring to fig. 3A, the connector housing 114 may include a coupler 142, the coupler 142 configured to engage a coupler 306 of at least one cable 300 to secure the at least one cable 300 to the connector housing 114. For example, the coupler 142 of the connector housing 114 may define an inner surface 142a, the inner surface 142a defining an opening 142b, the opening 142b configured to receive the coupler 306 of the at least one cable 300. In one example, when the inner surface 142a is along a first mating direction MA1The inner surface 142a tapers inwardly as it extends in the opposite and distal direction from the docking end 102. The coupler 306 may be a widened portion of the metal braid of the jacket 302 of the cable 300. The coupler 306 of the at least one cable 300 may include an outer surface 306a, the outer surface 306a being disposed along a first mating direction MA1And tapers as it extends in the opposite and distal direction from the mating end 102.

The metal braided sheath 302 of the cable 300 may be in the mating direction MA1Extending over flange 115j such that metal braided sheath 302 conforms to the shape of flange 115 j.Thus, the mounting end of the housing 115 including the flange 115j may be received in the metal braided sheath 302. The electrical connector 100 may include a leaf spring 311, the leaf spring 311 being received over the metal braided sheath 302 and the mounting end of the housing 115.

Thus, the flange 115j may act as a stop to interfere with the movement of the braided metal sheath 302 and the leaf spring 311 in opposite directions. Optionally, the electrical connector 100 may include a shrink wrap 310, the shrink wrap 310 being shrinkable over the interface between the metal braided sheath 302, the leaf spring 311, and the mounting end of the housing 115.

For example, the electrical connector 200 is along the second mating direction MA2May be longer than the electrical connectorA width of the electrical connector 200 in the lateral direction a and a height of the electrical connector 200 in the transverse direction T. However, it should be understood that in alternative examples, the electrical connector 200 need not be elongated in the longitudinal direction L.

One of the housing body 215 and the housing sheath 213 may include a protrusion, and the other of the housing body 215 and the housing sheath 213 may include a recess configured to receive the protrusion. For example, fig. 13A and 13B show a specific example in which the housing jacket 213 has a protrusion 209, the protrusion 209 extends outwardly from the housing jacket 213, and the housing body 215 defines a recess 211, the recess 211 extending outwardly from the cavity 217 of the housing body 215, wherein the recess 211 is configured to receive the protrusion 209.

The word "substantially" with respect to frequency includes frequencies described herein as well as frequencies within 5GHz above and below the described frequency (+/-5 GHz). Of course, it should be understood that the body 226 may be configured to attenuate other frequencies as desired. For example, the body 226 may be a broadband absorber. The body 226 may be tuned to attenuate frequency bands of frequencies wider than 1GHz, wider than 10GHz, wider than 20GHz, wider than 30GHz, wider than 40GHz, wider than 50GHz, wider than 60GHz, wider than 70GHz, wider than 80GHz, wider than 90GHz, or wider than 100 GHz.

The lossy material or metamaterial may be magnetically absorptive. In one example, the lossy material or metamaterial may be electrically conductive. For example, the conductivity of the lossy material or metamaterial may be greater than 1 siemens/meter up to about 6.1 x 107Siemens per meter. Alternatively, the lossy material or metamaterial may be non-conductive. For example, the conductivity of the lossy material or metamaterial can range from 1 siemens/m up to 1X 10-17Siemens per meter. Without being bound by theory, it is believed that the lossy material or metamaterial can improve signal integrity relative to a comparable design in which the substrate or board or an ungrounded substrate or board is not embedded or covered by the lossy material or metamaterial. The connector of the present disclosure can meet the 32 gigabit/second PCIE Express Gen 5 standard without the body 126, or when combined with the body 126 oneMay be implemented to be compatible with a 56 gbit/s NRZ or a 112 gbit/s PAM 4.

Accordingly, a dimension of the body 226 in the lateral direction a may be greater than a dimension of the body 226 in the transverse direction T. The body 226 may extend along the centerline CL in the lateral direction a. Referring briefly to fig. 15, the body 226 may have a lateral direction a and a mating direction MA2A substantially flat body. The body 226 is along the mating direction MA2Is greater than the dimension of the body 226 in the transverse direction T. The body 226 may have a generally rectangular front or insertion end. However, it should be understood that the front or insertion end may have another suitable shape. For example, the front or insertion end of the body 226 may be chamfered in a manner similar to that discussed above with respect to the front end 126a of the body 126. Chamfering the front or insertion end may make it easier to insert the body 226 into the inner housing body 218.
