The subject matter herein relates generally to header connectors.
Communication systems include electrical connectors, which are mated to electrically connect various components of the system. For example, a header connector may be mounted to a device, such as to a chassis, a panel, a circuit board, or another substrate, for mating with a plug connector. The plug connector may be terminated to a wire harness or another circuit board. The header connector typically includes a housing holding terminals or busbars, which are configured to be terminated to cables. The busbars are typically individually loaded into the header housing, which increases the number of components needed to be installed and assembled by the customer, which increases the assembly cost and complexity. During assembly, the header connector is typically loaded through an opening in the device (for example, a panel opening). The opening has a certain shape/size, known as a feed envelope, to feed the header connector through during assembly. The size of the header connector is limited by the size of the feed envelope to fit through the opening. The sizes and shapes of the busbars are limited by the size/shape of the feed envelope because the busbars need to pass through the opening.
A need remains for a header connector that may be assembled and installed in a cost effective and reliable manner.

For example, the mounting portion 164 may be located above, below, and at both sides of the support wall 162. The mounting portion 164 may have other shapes in alternative embodiments. For example, the mounting portion 164 may extend from the top and/or the bottom and/or the first side and/or the second side of the support wall 162. In the illustrated embodiment, the mounting portion 164 forms a ring around the support wall 162.
In an exemplary embodiment, the mounting portion 164 includes an end wall 170 and an outer wall 172. The end wall 170 extends between the support wall 162 and the outer wall 172. In an exemplary embodiment, the end wall 170 is located at the rear of the busbar carrier 160 and the outer wall 172 extends forward from the distal end of the end wall 170. The outer wall 172 forms the ring around the support wall 162. In an exemplary embodiment, the outer wall 172 includes slots 174 dividing the outer wall 172 into sections 176. The slots 174 allow the sections 176 to move relative to each other, such as for securing to the rear portion 123 of the header housing 110.
In an exemplary embodiment, the outer wall 172 of the mounting portion 164 includes latching features 178 configured to be latchably coupled to the header housing 110. In the illustrated embodiment, the latching features 178 are openings configured to receive latches extending from the rear portion 123 of the header housing 110. Other types of latching features may be used in alternative embodiments.
Each busbar 180 extends between a mating end 182 and a terminating end 184. The mating end 182 is configured to be connected to the plug connector 200. The terminating end 184 is configured to be connected to the power cable 102. In an exemplary embodiment, the busbar 180 is a stamped part. For example, the busbar 180 may be stamped from a sheet of metal. The busbar 180 may be generally planar. In the illustrated embodiment, the busbar 180 forms a blade 186 at the mating end 182 configured to be plugged into a socket of the plug contact 250 of the plug connector 200.

In an exemplary embodiment, the busbar 180 may include a load stop 192 extending from the side edges of the busbar 180. The load stop 192 is configured to engage the support wall 162. The load stop 192 positions the busbar 180 relative to the busbar carrier 160. For example, the busbar 180 may be rear loaded into the busbar channel 166 until the load stop 192 engages the rear surface of the support wall 162. The load stop 192 prevents forward loading of the busbar 180 once the load stop 192 is seated against the support wall 162. Other types of locating features may be used in alternative embodiments.
During assembly, the header housing 110 is coupled to the panel 20, such as from the front surface 22 of the panel 20. The rear portion 123 is loaded through the panel opening 30. The rear portion 123 is sized and shaped to fit through the panel opening 30. For example, the rear portion 123 is sized and shaped relative to the feed envelope of the panel opening 30 to allow the rear portion 123 to pass through the panel opening 30. For example, the rear portion 123 of the header housing 110 has a housing envelope having a height and a width. The housing envelope is smaller than the panel envelope allowing the rear portion 123 to pass through the panel opening 30. The header housing 110 is moved rearward toward the panel 20 until the mounting flange 134 bottoms out against the front surface 22 of the panel 20. The mounting flange 134 is dimensioned (for example, height and width) larger than the feed envelope of the panel opening 30 in at least one direction (for example, in all four directions in the illustrated embodiment) to bottom out against the panel 20 and not pass through the panel opening 30. The slide lock 140 is then coupled to the rear portion 123 of the header housing 110 to lock the header housing 110 to the panel 20. The slide lock 140 is dimensioned (for example, height and width) larger than the feed envelope of the panel opening 30 in at least one direction to bottom out against the panel 20 and not pass through the panel opening 30. The panel 20 is sandwiched between the mounting flange 134 and the slide lock 140. In an exemplary embodiment, the rear portion 123 extends rearward of the slide lock 140 for connection with the busbar carrier assembly 150.
During assembly, the busbars 180 are loaded into the busbar carrier 160. For example, the busbars 180 may be rear loaded into the busbar channels 166 in the support wall 162. The mating ends 182 of the busbars 180 extend forward of the support wall 162. The busbar carrier 160 holds the busbars 180 relative to each other at proper locations (for example, spacing) for mating with the plug connector 200. The busbar carrier assembly 150 is coupled to the rear portion 123 of the header housing 110. For example, the mating ends 182 of the busbars 180 are rear loaded into the cavity 114 of the header housing 110. The mating ends 182 are loaded to the front of the header housing to mate with the plug connector 200. The mating ends 182 pass through the panel 20, such as to a mating location located forward of the panel 20. The mating ends 182 are arranged at a spacing that fits within the panel envelope. In an exemplary embodiment, the support wall 162 supports the busbars 180 in the cavity 114. For example, the header housing 110 does not directly engage the busbars 180, but rather the busbars 180 are cantilevered into the cavity 114 by the support wall 162 of the busbar carrier 160. The front portion of the support wall 162 may be loaded into the cavity 114. The mounting portion 164 is coupled to the rear portion 123 of the header housing 110. For example, the rear portion 123 may be plugged into the space between the outer wall 172 and the support wall 162. The sections 176 may surround the rear portion 123. The latching features 178 are configured to be latchably coupled to the latches 125 at the rear portion 123 to secure the busbar carrier 160 to the rear portion 123. The busbar carrier 160 is removably coupled to the terminating end 118 of the header housing 110, such as by releasing the latching features 178 from the latches 125. The terminating ends 184 of the busbars 180 extend rearward from the busbar carrier 160. The terminating ends 184 are not loaded into the header housing 110 and thus may have any size and/or shape. The size and shape of the terminating ends 184 are not controlled by the size and shape of the header envelope because the terminating ends 184 do not have to pass through the header housing 110. Additionally, the terminating ends 184 are not loaded through the panel opening 30 and thus may have any size and/or shape. The size and shape of the terminating ends 184 are not controlled by the size and shape of the panel envelope because the terminating ends 184 do not have to pass through the panel opening 30. As such, the terminating ends 184 may be spread outward for connection or termination to the power cables. For example, the terminating ends 184 may be spread out to space the power cables 102 apart from each other for easier termination and/or to prevent electrical arcing therebetween.
