The second rib extends beyond the mounting end of the outer housing. The first rib, wall, and second rib provide a barrier between the power contacts to prevent arc discharge and increase the surface distance between adjacent contacts. The second rib is positioned in a slot in the mating substrate when the power connector is mounted to that substrate, thereby allowing the isolation of the power contacts to continue into the substrate. 【0013】 One embodiment relates to an electrical connector module having a signal connector and an input voltage connector, each having signal contacts. The housing of the input voltage connector has a mating end and a mounting end. The housing has contact receiving slots and a wall extending between the contact receiving slots. Power contacts are provided in the contact receiving slots. A first rib extends from the wall toward the mating end of the housing. A second rib extends from the mounting end of the housing.

Since many different configurations of the plug-in module 10 can be used, the illustrated plug-in module 10 is illustrative. For example, in the illustrated exemplary embodiment, the alignment / keying member 12, the first signal and output power connector 14, the second signal and output power connector 16, and the second alignment / keying member 20 are known and can be replaced with other components. 【0015】 The plug-in module 10 is mounted on the daughter card 22. As shown in Figure 9, the daughter card 22 has five mounting sections. The first mounting section 24 is configured to engage with the first alignment / keying member 12. The second mounting section 26 is configured to engage with the first signal and output power connector 14. The third mounting section 28 is configured to engage with the second signal and output power connector 16. The fourth mounting section 30 is configured to engage with the input voltage connector 18. The fifth mounting section 32 is configured to engage with the second alignment / keying member 20. 【0016】 Referring to FIGS. 3 - 5, an exemplary input voltage connector 18 has an outer housing 34, power contacts 36, and an inner fin housing 38. The outer housing 34 has slots 40 for receiving the contacts 36. In the illustrated exemplary embodiment, four slots 40 are shown. The slots 40 extend from the mating end 44 of the outer housing 34 to the mounting end 43 of the outer housing 34. The slots 40 are separated by walls 45. Ribs 42 extend from the walls 45 and extend towards the mating end 44 of the housing 34. Recesses 41 are provided in the walls 45. The recesses 41 are spaced from the ribs 42 and extend towards the mounting end 43 of the outer housing 34. 【0017】 In the illustrated exemplary embodiment, four power contacts 36 are shown. The contacts 36 have mating tabs 46, body portions 47, and compliant pins or solder posts 48. The mating tabs 46 and the compliant pins or solder posts 48 extend from the body portion 47 in different directions. In the illustrated exemplary embodiment, the compliant pins or solder posts 48 extend from the body portion 47 essentially perpendicular to the mating tabs 46. However, other numbers and configurations of contacts 36 may be used. 【0018】 The inner fin housing 38 has slots 50 for receiving a portion of the body portion 47 of the contacts 36. In the illustrated exemplary embodiment, four slots 50 are shown. The slots 50 are separated by walls 52. The walls 52 extend from the rear wall 53 of the inner fin housing 38. The inner fin housing 38 further has ribs 54. The ribs 54 extend from the walls 52 and are disposed proximate to the compliant pins or solder posts 48 of the contacts 36. As shown in FIG. 3, when the inner fin housing 38, the contacts 36, and the outer housing 34 are assembled, the wall 52 of the inner fin housing 38 is disposed in the recess 41 of the wall 45 of the outer housing 34 and extends into the slot 40. In an exemplary embodiment, the outer housing 34 and the inner fin housing 38 are separate members or components. However, in other exemplary embodiments, the outer housing 34 and the inner fin housing 38 may be integrally formed as one piece. 【0019】 FIG. 9 illustrates a daughter card 22 to which a plug-in module 10 is attached. A fourth mounting section 30 configured to engage the input voltage connector 16 has a slot 58 disposed between plated through holes or receiving openings 56. The receiving openings 56 are configured to receive compliant pins or solder posts 48 of the contacts 36. The slot 58 is configured to receive the ribs 54 of the inner fin housing 38. 【0020】 When the input voltage connector 18 of the plug-in module 10 is properly assembled, the walls 45 and ribs 42 of the outer housing 34 cooperate with the walls 52 and ribs 54 of the inner fin housing 38 to isolate the mating tabs 46, body portions 47, and compliant pins or solder posts 48 of the power contacts 36 from other power contacts 36 and from the first signal and output power connector 14 and the second signal and output power connector 16. In a three-phase application example, this enables isolation of phases A / B / C and the neutral line from each other. For other power application examples such as, but not limited to, 270V and 28V, the walls 45 and ribs 42 of the outer housing 34 and the walls 52 and ribs 54 of the inner fin housing 38 provide a barrier between the power contacts 36 to prevent arc discharge and also provide an increase in the surface distance between adjacent contacts 36. 【0021】 When the input voltage connector 18 of the plug-in module 10 is mounted to the daughter card 22, the compliant pins or solder posts 48 of the contacts are positioned in the receiving openings 56 of the fourth mounting section 30 of the daughter card 22. Furthermore, the ribs 54 of the inner fin housing 38 are positioned in the slots 58 of the fourth mounting section 30 of the daughter card 22. By positioning the ribs 54 in the slots 58, the isolation of the power contacts 36 continues to the daughter card 22, thereby promoting a more reliable connection. 【0022】 Referring to Figures 2 and 10, an exemplary backplane module 110 includes an alignment / keying member 112, a first signal and output power connector 114, a second signal and output power connector 116, an input voltage connector 118, and a second alignment / keying member 120. The backplane module 110 is configured to allow mating with the plug-in module 10. Since many different configurations of the backplane module 110 are available, the illustrated backplane module 110 is illustrative. For example, in the illustrated exemplary embodiment, the alignment / keying member 112, the first signal and output power connector 114, the second signal and output power connector 116, and the second alignment / keying member 120 are known and can be replaced with other components. 【0023】 The backplane module 110 is mounted on the backplane 122. As shown in Figure 11, the daughter card 122 has five mounting sections. The first mounting section 124 is configured to engage with the first alignment member 112. The second mounting section 126 is configured to engage with the first signal and output power connector 114. The third mounting section 128 is configured to engage with the second signal and output power connector 116. The fourth mounting section 130 is configured to engage with the input voltage connector 116. The fifth mounting section 132 is configured to engage with the second alignment / keying member 118. 【0024】 Referring to Figures 2, 3 and 10, an exemplary input voltage connector 118 has a housing 134 and power contacts 136. The housing 134 has slots 140 for receiving the contacts 134. In the exemplary embodiment, four slots 140 are shown, corresponding to slots 40 of the input voltage connector 18. The slots 140 extend from the mating end 144 of the housing 134 to the mounting end 143 of the housing 134. The slots 140 are separated by a wall 145. A rib 142 extends from the wall 145 and extends toward the mating end 144 of the housing 134. A recess 141 is provided in the wall 145. The recess 141 is spaced apart from the rib 142 and extends toward the mounting end 143 of the outer housing 134. The recess 141 is configured to receive the power contact 136. 【0025】 In the illustrated exemplary embodiment, four contacts 136 are illustrated. Each contact 136 has a mating portion 146 and a compliant pin or solder post 148. In the illustrated exemplary embodiment, the mating portion 146 and the compliant pin or solder post 148 of each contact 136 are arranged essentially in a row. However, other numbers and configurations of contacts 136 may be used. 【0026】 The housing 134 has ribs 154 that extend from the wall 145 and are positioned close to the compliant pins or solder posts 148 of the contact 136. The wall 145 and the ribs 154 may be integrally molded together or may be separate components. 【0027】 Figure 11 illustrates the backplane 122 to which the backplane module 110 is mounted. A fourth mounting section 130 configured to engage with the input voltage connector 116 has a slot 158 ​​positioned between plated through holes or receiving openings 156. The receiving openings 156 are configured to receive compliant pins or solder posts 148 of the contacts 136. The slot 158 ​​is configured to receive the ribs 154 of the housing 134. 【0028】 When the input voltage connector 118 of the backplane module 110 is properly assembled, the walls 145, ribs 142, and ribs 154 isolate the mating portion 146 and compliant pins or solder posts 148 of the power contacts 136 from other power contacts 136, as well as from the first signal and output power connector 114 and the second signal and output power connector 116. In three-phase applications, this allows for isolation of phases A / B / C and the neutral wire from each other. In other power applications, such as 270V and 28V, but not limited to these, the walls 45 and 145, ribs 142, and ribs 154 provide a barrier between the power contacts 136 to prevent arc discharge and further increase the surface distance between adjacent contacts 136. 【0029】 When the input voltage connector 118 of the backplane module 110 is mounted to the backplane 122, the compliant pins or solder posts 148 of the contact 136 are positioned in the receiving opening 156 of the fourth mounting section 130 of the backplane 122. Furthermore, the rib 154 of the housing 134 is positioned in the slot 158 ​​of the fourth mounting section 130 of the backplane 122. By positioning the rib 154 in the slot 158, the isolation of the power contact 136 continues to the backplane 122, thereby promoting a more reliable connection. 【0030】 As shown in Figure 3, when the plug-in connector 10 and the backplane connector 110 are mated, the ribs 42 of the outer housing 34 and the ribs 142 of the housing 134 provide a barrier between the mated contacts 36 and 136, preventing arc discharge and increasing the surface distance between adjacent contacts. 【0031】 Figures 12 and 13 show a second exemplary embodiment. In this exemplary embodiment, the configuration of the alignment / keying alignment member 212, the first signal and output power connector 214, the second signal and output power connector 216, the input voltage connector 218, and the second alignment / keying member 220 may differ from the alignment / keying member 12, the first signal and output power connector 14, the second signal and output power connector 16, the input voltage connector 18, and the second alignment / keying member 20 of the embodiment described above, however the operation of the input voltage connector 218 remains the same as that of the input voltage connector 18. In this embodiment, the input voltage connector 218 and the second signal and output power connector 216 include power contacts 236. Each power contact 236 is surrounded by an outer housing and an inner fin housing, as described above with reference to the first embodiment. 【0032】 Similarly, the configurations of the alignment / keying alignment member 312, the first signal and output power connector 314, the second signal and output power connector 316, the input voltage connector 318, and the second alignment / keying member 320 may differ from those of the alignment / keying alignment member 112, the first signal and output power connector 114, the second signal and output power connector 116, the input voltage connector 118, and the second alignment / keying member 120 in the embodiments described above, but the operation of the input voltage connector 318 remains the same. In this embodiment, the input voltage connector 318 and the second signal and output power connector 316 include power contacts 336. Each power contact 336 is surrounded by a housing as described above with reference to the first embodiment. 【0033】 Figure 14 shows a third exemplary embodiment. In this embodiment, the voltage connector 418 is independent of the other connectors and is mounted on the daughter card 422 and the voltage backplane 522. The components and operation of the voltage connector 418 are the same as those described above with respect to the voltage connector 18.
