Abstract

An electrical connector includes a housing including a front housing and a rear housing matable to define the housing. The front housing and the rear housing are molded as a single piece with a hinge member connecting the front housing and the rear housing. The rear housing is rotatable about the hinge member from an open position to a closed position. The front housing has front terminal channels configured to receive terminals and the rear housing has rear terminal channels aligned with the front terminal channels when the rear housing is rotated to the closed position but not aligned with the front terminal channels when the rear housing is in the open position. The rear terminal channels are configured to allow the terminals to at least partially pass therethrough into the front terminal channels during loading of the terminals into the housing.
