INSTRUCTIONS: [Prior Art] Electrical connectors can use signal contacts to provide signal connections between electronic devices. The electrical connector can include a leadframe assembly having a dielectric leadframe housing and a plurality of electrical contacts extending therethrough. Typically, the electrical contacts within the leadframe assembly are arranged in a linear array that extends in the direction along which the leadframe housing is elongated. The contacts may be arranged in an edge-to-edge manner along the direction in which the linear array extends. Electrical contacts in one or more leadframe assemblies form a differential signal pair. A differential signal pair can consist of two contacts carrying differential signals. The value or amplitude of the differential signal can be the difference between the individual voltages at each contact. The contacts forming the pair may be wide-edge bonded (i.e., configured such that the wide sides of one of the contacts face the wide side of the other contact with which the pair is formed). A wide-edge or microstrip bond is typically required as a mechanism for controlling (e.g., minimizing or eliminating) the skew between the contacts forming the differential signal pair. When designing a printed circuit board (PCB), the circuit designer typically establishes the desired differential impedance for the traces that form the differential signal pairs on the pCB. Therefore, it is usually necessary to maintain the same desired impedance between the differential shunt contacts in the electrical connector. The length of the dot (from the clamping end to its mounting end) maintains a constant differential impedance profile. . It may be further desirable to minimize or eliminate insertion loss (i.e., decrease in signal amplitude caused by the insertion of the electrical connector into the path of the signal 2). The insertion loss can be a function of the operating frequency of the electrical connector. That is, the insertion loss can be compared to the fine frequency of only π 乂 乂 125 N. 125509.doc 200828688 Therefore, there is a need for a high-speed electrical connector that minimizes insertion loss at higher operating frequencies. , _ maintains the desired differential impedance between the differential signal contacts. SUMMARY OF THE INVENTION The disclosed embodiments include an electrical connector having a __first electrical contact and a second electrical contact adjacent to the first electrical contact. The first electrical contact defines a -th wide side and a second wide side opposite the first wide side. The second electrical contact defines a third wide side and a fourth wide side opposite the third wide side. The electrical connector can include a non-air dielectric and a common ground plane. The non-wire dielectric can be disposed between the second wide side of the first electrical contact and the fourth wide side of the second electrical contact. The common ground plane and the first electrical contacts may be adjacent to each other and may be separated by an air dielectric. [Embodiment] Figs. 1A and 1B respectively depict an isometric view and a side view of a prior art connector system. The connector system 1A includes a plug connector 1〇2 that is mated to a receptacle connector 104. The plug connector 1〇2 can be mounted to a first substrate such as printed circuit board 106. The receptacle connector 1〇4 can be mounted to a second substrate (such as printed circuit board 108). The plug connector 1〇2 and the receptacle connector 104 are not shown as vertical connectors. That is, the plug connector 1〇2 and the receptacle connector 104 each define a mating plane that is generally parallel to its respective mounting plane. The plug connector 102 can include a connector housing, a base 11 〇, a lead frame assembly 126, and electrical contacts 114. The connector housing of the plug connector i〇2 may include an interface portion 1〇5 defining one or more recesses 1〇7. As will be discussed in the following paragraph 125509.doc 200828688, the recess 107 can receive a portion of the receptacle connector i〇4 and thus can help provide mechanical rigidity and support to the connector system 1〇〇. Each of the leadframe assemblies 126 of the header connector 102 can include a first leadframe housing 128 and a second leadframe housing 130. The first lead frame peripheral 128 and the second lead frame housing 13 can be made of a dielectric material such as plastic. Lead frame assembly 126 can be an insert molded leadframe assembly and can accommodate a linear array of electrical contacts i 14 . For example, as will be discussed further below, an array of electrical contacts 114 can be disposed edge-to-edge in each leadframe assembly 126 (ie, the edges adjacent to electrical contacts U4 can face each other) ). The electrical contacts 114 of the header connector 102 can each have a cross section defining two opposing edges and two opposing wide sides. Each electrical contact 1 14 can also define at least three portions along its length. For example, as shown in FIG. 1B, each electrical contact 114 can define a mating end 116, a lead portion 118, and a terminating end 121. The mating end 116 can be blade-shaped and can be received by respective electrical contacts 136 of the receptacle connectors 1〇4. The termination end 121 can be "tough," and thus can be press fit into one of the apertures 124 of the substrate 110. The termination end 121 can be aligned with a ball grid array on the substrate surface 122 of the substrate 11 (Bga, ball grid array The i25 is electrically connected. The lead portion 118 of the electrical contact 114 can extend from the terminating end 121 to the mating end 116. The substrate 11 of the plug connector 102 can be made of a dielectric material such as plastic. The substrate 11 can define a A plane of the connector surface 12 and the substrate surface 122. The plane defined by the substrate 110 can be substantially parallel to a plane defined by the printed circuit board 106. As shown in Figure 1A, the substrate 11 is connected to the connector 125509. Doc 200828688 The face 120 can define an aperture 124 that receives the terminating end 121 of the electrical contact 114. The substrate face 122 of the substrate 110 can include a BGA 125 that can electrically connect the electrical contact 114 to the printed circuit board 106. The receptacle connector 104 can A connector housing, a base 112, a lead frame assembly 132, and an electrical contact 136 are included. The connector housing of the receptacle connector 1〇4 can include an interface portion 1〇9 defining one or more ridges 111. Plug connector 102 and socket connector 1 4, the ridge 111 on the connector housing of the socket connector 1 〇 4 can be engaged with the groove 107 on the connector housing of the plug connector i 02. Therefore, as indicated above, the groove and The ridges 111 can provide mechanical rigidity and support to the connector system 1. The lead frame assembly 132 of the receptacle connector 104 can include a leadframe housing 133. The leadframe housing 133 can be made of a dielectric material (such as Each of the leadframe assemblies 132 can be an insert molded leadframe assembly (IMLA) and can accommodate a linear array of electrical contacts 136. For example, an electrical connection can be made. The array of dots 13 6 is disposed in the lead frame assembly 132 in an edge-to-edge manner (ie, the edges adjacent the electrical contacts 136 may face each other). Similar to the electrical contacts 114, the receptacle connectors 1 〇 4 The electrical contact 136 can have a cross section defining two opposing edges and two opposing wide sides. Each electrical contact 136 can define at least three portions along its length. For example, as shown in Figure 1β, each An electrical contact 136 can define a mating end 141, a lead portion 144, and a The end 146. The mating end 141 of the electrical contact 136 can be any socket for receiving a male contact, such as the blade-like mating end 6 of the electrical contact 114. For example, the mating end 141 can include A slot is defined therebetween to 125509.doc 200828688 with two opposing tines 1 4 8 . The slot of the mating end 14 1 can accommodate the blade-like mating end 116 of the electrical contact ii 4 . (i.e., the distance between the opposing tines 148) may be less than the thickness of the blade-like mating end 116. Thus, a relatively large return 14 8 can apply a force to each side of the blade-like mating end 116, thereby retaining the mating end 116 of the electrical contact 114 in the mating end 142 of the electrical contact 136. Alternatively, as shown in Figure 1A, the mating end 141 can include a single tines 148 configured to contact one side of the blade-like mating end 116. The terminating end 146 of the electrical contact 136 can be ''tough'' and thus can be press fit into one of the apertures (not shown) of the substrate 112. The termination end ι 46 can be electrically coupled to a ball grid array (Bga) 142 on the substrate surface 140 of the substrate 112. Lead portion 144 of each electrical contact 136 can extend from termination end 146 to mating end 141. The base 112 of the receptacle connector 104 can be made of a dielectric material such as plastic. Substrate 112 can define a plane having a connector face 138 and a substrate face 140. The plane defined by the substrate 112 can be generally parallel to a plane defined by the printed circuit board 108. The connector face 138 can define an aperture (not shown) for receiving the terminating end 146 of the electrical contact 136. Although the aperture of the substrate 112 is not shown in Figures 1A and 1B, the aperture in the connector face 138 of the substrate 112 can be the same or similar to the aperture 124 in the connector face 120 of the substrate 110. The substrate surface 140 can include a BGA 142 that can electrically connect the electrical contacts 136 to the printed circuit board 108. Figure ic depicts one of the contact configurations 190 as viewed from the face of the plug connector 102, wherein the electrical contacts 114 are arranged in a linear array. As shown in Figure ic, the electrical contacts 114 can be configured in a 5x4 array, although it should be understood that the header connector 102 can include any number of electrical contacts 114 configured in a variety of configurations. Plug connector 102 can include contact trains 15A, 152, 154, 156, 158 and contact rows 160, 162, 164, 166, as shown in 125509.doc - 10 200828688. As noted above, each of the electrical contacts 114 can have a cross section defining two opposing edges and two opposing wide sides. The electrical contacts 114 can be configured in an edge-to-edge manner along each of the rows 16〇, 162, 164 166. Alternatively, the electrical contacts 114 can be disposed along the wide sides to the wide sides along each of the columns 15A, 152, 154, 156, 158. As shown in Figure (1), the wide sides of the electrical contacts 114 in the columns 150, 154, 158 can be smaller than the wide sides of the electrical contacts 114 in the columns 152, ι 56. Each of the electrical contacts 114 can be surrounded by a dielectric 176 (which can be air) on all sides. The electrical contacts 114 in the header connector 102 can include a ground contact G and a signal contact S. As shown in FIG. 1C, the columns 15 154, 154, 158 of the plug connector ι 2 may include all of the ground contacts g. The plug connectors 〇2, 152, ι 56 may include both the ground contact G and the signal contact S. For example, the electrical contacts 丨丨4 in the arrays 52, 156 can be configured in the G-S-S-G mode. As noted above, the electrical contacts 114 can be disposed along the wide sides to the wide sides along each of the columns 150, 152, 154, 156, 158. Thus, adjacent signal contacts S in columns 152, 156 can form a wide-edge junction differential signal pair (such as differential signal pair 174 shown in Figure ic). 2A and 2B depict an isometric view and a side view, respectively, of a connector system 2A, in accordance with an embodiment. The connector system 2A can include a plug connector 202 that mates to the receptacle connector 104. Plug connector 202 can be mounted to printed circuit board 106. The receptacle connector 1〇4 can be mounted to the printed circuit board 108. Plug connector 202 and receptacle connector 104 are shown as vertical connectors. However, either or both of the plug connector 2〇2 and the receptacle connector 1〇4 or both may be right angle connectors in alternative embodiments. The header connector 202 can include a base 110, a lead frame assembly 126, and an electrical contact 114. As shown in Figure 2B, the header connector 2A2 can further include a non-air dielectric (such as dielectric material 204) that must be located adjacent the leadframe assembly 126. In particular, the dielectric material 2〇4 can be positioned between adjacent lead frame assemblies that house one or more signal contacts s. The dielectric material 2〇4 can be made of any suitable material such as plastic. Dielectric material 2〇4 can be molded as part of leadframe assembly 126. Alternatively, dielectric material 204 can be molded separately from leadframe assembly 126 and subsequently inserted between the leadframe assemblies. 2C depicts a side view of dielectric material 2〇4. As shown in Figure %, the dielectric material 204 can include head portions 2〇5a, 205b that extend generally parallel to each other. The dielectric material can further include interconnecting portions 206b that extend generally parallel to each other and that are generally perpendicular to the head portions 205a, 2〇5b. The 荨 interconnecting portion 2〇6a, 206b can connect the head portion 2〇5a to the head portion 2〇5b. As noted above with reference to Figures 2A and 2B, the dielectric material 2〇4 can be disposed adjacent to the lead frame assembly 126 having the signal contacts s (i.e., the inner lead frame shown in Figure 2A and Figure). Between the assembly 126). More specifically, the head portion 2〇5a of the dielectric material = 204 may be adjacent to the first lead frame housing 128 and may extend in length. The head portion 2〇 of the dielectric material 204 can be adjacent to the second individual lead frame housing 130 and can extend along its length. Thus, the head 2 portions 205a, 205b can be disposed adjacent to at least a portion of each of the electrical contacts 114 in the inner lead frame assembly 126. The interconnect portion of the dielectric material 2〇4 125509.doc -12- 200828688 206a, 206b may extend substantially parallel to the electrical contacts 114 in the inner leadframe assembly 126. In particular, as will be discussed further below, the interconnect portions 206a, 206b can extend along the length of each of the signal contacts received in the inner lead frame assembly 126. 2D depicts a contact arrangement 290 as viewed from the face of plug connector 202, which includes a linear array of electrical contacts 114 and a portion of dielectric material 204. Similar to the contact configuration depicted in Figure ic, the electrical contacts 114 can be configured in a 5x4 array' and can define contact columns 15A, 152, 154, 156, 158 and contact rows 160, 162, 164, 166. The electrical contacts 114 in the header connector 202 can have a cross section defining two opposing edges and two opposing wide sides. The electrical contacts 114 can be configured in an edge-to-edge manner along each of the rows 160, 162, 164, 166. In addition, the electrical contacts 丨14 can be arranged along the wide side to the wide side along each of the columns 150, 15, 2, 4, 4, 1, 5, and 1 5 8 . The wide sides of the electrical contacts 114 in the columns 150, 154, 158 may be smaller than the wide sides of the electrical contacts 114 in the columns 152, 156. The electrical contacts 114 in the header connector 202 can also include a ground contact g and a signal contact S. The columns 15 〇, 154, ι 58 of the header connector 202 may include all of the ground contacts G ′ and the columns 152 , 156 may include both the ground contacts G and the signal contacts S . For example, the electrical contacts 114 in the columns 152, 156 can be configured in a G-S-S-G mode. The electrical contacts 丨丨4 can be arranged along the broad side to the wide side along each of the columns 15〇, 152, 154, 156, ι58. Thus, the adjacent signal contacts 8 in the arrays 52, 156 can form a wide-edge junction differential signal pair 174. As shown in FIG. 2D, the interconnecting portions 206a, 206b of the dielectric material 204 can define a generally rectangular cross section and can be positioned in rows 162, ι 64 of 125509.doc -13 - 200828688 adjacent signal contacts s between. That is, the interconnecting portions 2〇6a, 2〇6b can be positioned between the wide-side of the plug connector 202 and the signal contact S of the differential signal pair 74, but may not be in close proximity to the differential signal pair. Ground contact. Additionally, each of the electrical contacts 114 can be surrounded by a dielectric 176 on all sides, which dielectric 176 can be different than the dielectric material 2〇4 disposed between the wide-side junction differential signal pairs 174. As further shown in FIG. 2D, the interconnecting portions 2A, 6a, 2b can extend a greater distance in the direction of columns 150, 152, 154, 156, 158 than each of the electrical contacts 114 (ie, The interconnect portions 2〇6a, 2〇6b may be comparable to the electrical contacts 114 I), but it should be understood that the width of the interconnect portions 2〇6a, 206b may be equal to or less than the width of the electrical contacts 114 in other embodiments. Additionally, interconnect portions 206a, 206b may extend substantially the same distance from each of electrical contacts 114 in the direction of contact rows 160, 162, 164, ι 66 (i.e., in interconnect portions 206a, 206b) Each of the heights may be substantially the same height as the electrical contacts 114 in the contact columns 152, ι 56, but it should be understood that the height of the interconnect portions 206a, 206b may be greater or less than the electrical connections in other embodiments. The height of point 114. 3A and 3B depict an isometric view and a side view, respectively, of a connector system 3 〇 根据 according to another embodiment. Connector system 300 includes a plug connector 302 that mates to receptacle connector 104. Plug connector 302 can be mounted to printed circuit board 106. The socket connector 1 〇4 can be mounted to the printed circuit board 1 〇 8. The plug connector 302 and the receptacle connector 1〇4 are shown as vertical connectors. However, it should be understood that either or both of the plug connector 302 and the receptacle connector 1 〇 4 may be right angle connectors in alternative embodiments. 125509.doc -14- 200828688 Plug connector 302 can include a substrate no, a leadframe assembly ι26, and an electrical contact 114. As shown in Figure 3A, the header connector 3 〇 2 can further include a common ground plate 178 that is received in at least one of the lead frame assemblies 126. The common ground plate 178 can be a continuous, electrically conductive sheet extending along the entire row of contacts and brought to the ground, thereby shielding all of the electrical contacts 114 adjacent the common ground plate 178. The common ground plate 178 can include a plate portion 18A, a terminating end 182, and a mating interface 184. More specifically, the plate portion 180 of the common ground plate 178 can be received within the lead frame assembly 126 and can extend from the terminating end 182 to the mating interface 184. As shown in FIG. 3A, the common ground plate 178 can include a terminating end 182 extending from the plate portion 18A and extending from the second leadframe housing 130 of the leadframe assembly 126. The terminating end 1 82 can be tough and can therefore be press fit into the aperture 124 of the substrate 1 . The terminating end 182 of the common ground plate 178 can be electrically coupled to the BGA 125 on the bottom side 122 of the substrate 11A. The common ground plate 178 can also include a mating interface 184 extending from the plate portion 18A and extending over the first leadframe housing 128 of the leadframe assembly 126. The mating interface 184 can be blade-shaped and can be received by the respective mating ends 14 1 of the electrical contacts 136. 3C depicts a contact configuration 39〇 viewed from the face of the plug connector 3〇2, which includes a linear array of electrical contacts 114 and common ground plates 178a, 178b. Electrical contacts 114 and common ground plates 178a, 178b can be arranged in a 5x4 array and can define contact columns 150, 152, 154, 156, 158 and contact rows 160, 162, 164, 166. Similar to the contact configuration depicted in Figure 1C, the electrical contacts 114 in the header connector 302 can have a cross section defining two opposing edges and two opposing wide sides of 125509.doc -15 - 200828688.

The wide sides of the electrical contacts 114 in the columns 150, 154, 158 may be smaller than the wide sides of the electrical contacts 114 in the columns 152, 156. The common ground plates 178a, 178b can be positioned adjacent to the contact rows 162, 164, respectively. Thus, as shown in FIG. 3C, the common ground plates 178a, 178b can be substituted for the ground contacts G in the contact rows 16A, 166 shown in FIG. 1C. The electrical contacts 114 in the header connector 302 can include a ground contact G and a signal contact S. The columns 15 154, 154, 158 of the header connector 302 can include all of the ground contacts G' and the columns 152, 156 can include both the ground contacts G and the signal contacts s. For example, the common ground planes 178a, 178b and the electrical contacts 114 in the columns 152, 156 can be configured in a G-S-S_G mode. The electrical contacts 114 can be configured along the broad side to the wide side along each of the columns 150, 152, 154, 150, 158.

The common ground plates 178a, 178b may each have a cross section of a generally rectangular shape. As shown in Figure 3C, the common ground plates 178a, 178b can each extend substantially the entire length of the contact rows 160, 162, 164, 166. The common ground plates 178a, 178b may also extend substantially the same distance from each of the electrical contacts 1丨4 in the direction of the contact train (ie, each of the common ground plates 78a, 178b may There is substantially the same width as the electrical contacts 114, but it should be understood that the width of the common ground plates 178a, 178b may be less than or greater than the width of the electrical contacts 114 in other embodiments.

Connector system 400 can include a plug connector 402 that mates to a socket connector 104. Plug connector 402 can be mounted to printed circuit board 106. The receptacle connector 1〇4 can be mounted to the printed circuit board 108. The plug connector 402 and the receptacle connector 1〇4 are shown as vertical connectors.

The header connector 4A2 can include a substrate 110, a leadframe assembly 126, electrical contacts 114, common ground pads 178a, 178b, and a dielectric material 204. 4C depicts a contact arrangement 490 as viewed from the face of plug connector 402, which includes a linear array of electrical contacts 114, common ground plates 178a, 17A, and dielectric material 204. As shown in Figure 4C, the interconnecting portions 206a, 206b of the dielectric material 204 can define a generally rectangular cross section and can be positioned between the signal contacts s in the contact rows 162, 164. That is, the interconnect portions 206a, 206b can be positioned between the wide side junction differential signal pairs 174 in the contact rows 162, ι64. In addition, each of the electrical contacts 114 and the common ground plates 178a, 17A can be surrounded by a dielectric 176 on all sides, the dielectric 176 being different from being disposed between the wide-side coupled differential signal pairs 174 Dielectric material 204 ° As further shown in FIG. 4C, the common ground plates 178a, 17A can be positioned adjacent to the contact rows 162, 164, respectively. Therefore, the common ground plates 178a, 178b can be substituted for the ground contacts G in the contact rows ι60, ι 66 shown in FIG. 1C. The common ground plates 178a, 178b may each have a cross section of a generally rectangular shape 125509.doc -17- 200828688. As shown in Figure 4C, the common ground plates 178a, 178b can each extend substantially the entire length of the contact rows 160, 162, 164, 166. The common ground plates 178a, 178b may also extend substantially the same distance from each of the electrical contacts 114 in the direction of the contact columns (ie, each of the common ground plates 78a, 178b may have electrical and electrical The contacts 114 have the same width), but it should be understood that the width of the common ground plates 178a, 178b may be less than or greater than the width of the electrical contacts 114 in other embodiments. It has also been found that the embodiment as described herein splits the coupling wave of the up-shift connector, thereby creating an insertion loss of about 4 GHz. The purpose of the dielectric material 204 is to slightly change the signal to the ground. The impedance is minimized by minimizing the coupling wave and its associated insertion loss. The ground plane minimizes the signal pair that is bonded to the grounded individual pin edge and provides a continuous ground plane.
