An electrical connector is provided that includes a housing that has a mating end and a carrier receiving end. The housing includes a rail that extends through the carrier receiving end into a chamber defined by the housing. The electrical connector also includes a carrier configured to be loaded into the chamber from the carrier receiving end. The carrier has terminal channels that are configured to receive terminals therein, and retention latches configured to retain the terminals in the terminal channels. The carrier also has a groove that is configured to receive the rail of the housing when the carrier is loaded within the housing. When a terminal is not fully inserted within a terminal channel, the retention latch in the terminal channel is deflected outward into the groove. The retention latch interferes with the rail of the housing and prevents further advancement of the carrier into the chamber.

1. An electrical connector comprising: a housing having a mating end and a carrier receiving end, the housing including a rail that extends from the carrier receiving end into a chamber defined by the housing, anda carrier configured to be loaded into the chamber through the carrier receiving end, the carrier having terminal channels spaced along a width that are configured to receive terminals therein, the carrier having retention latches within the terminal channels configured to retain the terminals in the terminal channels, the carrier also having a groove extending along the width of the carrier that is configured to receive the rail of the housing when the carrier is loaded within the housing,wherein, when one of the terminals is not fully inserted within one of the terminal channels, the corresponding retention latch in the terminal channel is deflected outward at least partially into the groove such that the retention latch interferes with the rail of the housing and prevents further advancement of the carrier into the chamber. 2. The electrical connector of claim 1, wherein when the carrier is loaded fully into the housing, the rail prohibits the retention latches from deflecting outward of the terminal channel. 3. The electrical connector of claim 1, wherein the terminal includes a latch opening that is configured to receive a locking surface of the retention latch therein when the terminal is in a fully loaded position within the carrier, the locking surface configured to prevent rearward movement of the terminal relative to the terminal channel. 4. The electrical connector of claim 3, wherein when the locking surface of the retention latch is received in the latch opening of the terminal, the retention latch is not deflected into the groove and does not interfere with the rail of the housing, allowing the carrier to be advanced further into the chamber. 5. The electrical connector of claim 1, wherein the ten Anal channels are aligned along parallel terminal channel axes, and the groove extends perpendicular to the terminal channel axes. 6. The electrical connector of claim 5, wherein the carrier is loaded into the housing in a loading direction that is perpendicular to the terminal channel axes. 7. The electrical connector of claim 1, wherein the mating end of the housing is adjacent to the carrier receiving end that receives the carrier. 8. The electrical connector of claim 1, wherein the terminal includes a socket that aligns with a lead-in opening at the mating end of the housing. 9. The electrical connector of claim 1, wherein the terminals are terminated to wires of a wire harness. 10. The electrical connector of claim 1, wherein the housing includes at least two rails that are located on different inner walls, each rail configured to be received in a groove of a different carrier. 11. An electrical connector comprising: a carrier having terminal channels spaced along a width of the carrier and a track on an outer surface of the carrier that extends along the width, the terminal channels configured to receive terminals therein for connecting to mating contacts of a mating connector, the carrier including retention beams mounted inward of the outer surface and extending into the terminal channels; anda housing that receives and at least partially surrounds the carrier, the housing including a rail that is received in the track of the carrier when the carrier is loaded into the housing;wherein until a terminal that is being inserted into a corresponding terminal channel reaches a fully loaded position within the terminal channel, the terminal deflects the corresponding retention beam in the terminal channel outward at least partially into the track, which interferes with the rail of the housing and prevents further advancement of the carrier into the housing beyond the retention beam. 12. The electrical connector of claim 11, wherein the terminal includes a latch opening that is configured to receive a locking surface of the retention beam therein when the terminal is in the fully loaded position, the locking surface configured to engage an edge of the terminal to prevent rearward movement of the terminal relative to the terminal channel. 13. The electrical connector of claim 12, wherein the retention beam is biased towards the terminal channel, and when the locking surface of the retention beam is received in the latch opening of the terminal, the retention beam pivots toward the terminal channel and away from the track, allowing the carrier to be advanced further into the housing beyond the retention beam. 14. The electrical connector of claim 11, wherein when the carrier is loaded fully within the housing, the rail is located proximate to an outer side of the retention beams, and the rail prohibits the retention beams from deflecting outward of the terminal channels. 15. The electrical connector of claim 11, wherein the terminal channels are aligned along parallel terminal channel axes, and the track extends perpendicular to the terminal channel axes. 16. The electrical connector of claim 15, wherein the carrier is loaded into the housing in a loading direction that is perpendicular to the terminal channel axes. 17. An electrical connector comprising: a housing having a mating end configured to interface with a mating connector and a carrier receiving end adjacent to the mating end, the housing including a rail protruding from an inner wall and extending from the carrier receiving end into a chamber defined by the housing; anda carrier having a front and a rear and defining multiple terminal channels between the front and the rear that are oriented along parallel terminal channel axes and configured to receive terminals therein, the carrier having retention latches configured to retain the terminals in the terminal channels, the carrier configured to be loaded into the chamber of the housing through the carrier receiving end in a loading direction that is perpendicular to the terminal channel axes such that the front of the carrier is proximate to the mating end of the housing, the carrier including a groove extending along an outer surface across the terminal channels that is configured to receive the rail of the housing when the carrier is loaded within the housing such that the rail extends across the terminal channels, the rail providing retention latch reinforcement for each of the retention latches. 18. The electrical connector of claim 17, wherein the retention latches of the carrier each have a locking surface that is received in a latch opening of the corresponding terminal and engages an edge of the terminal to prevent rearward movement of the terminal. 19. The electrical connector of claim 17, wherein if the terminals in the terminal channels are not in a fully loaded position, the corresponding retention latches are deflected outward at least partially into the groove and interfere with the rail when the carrier is advanced into the housing. 20. The electrical connector of claim 17, wherein the rail prohibits the retention latches from deflecting outward from the terminal channels, supporting retention of the terminals within the terminal channels.
