Through mount connector with alignment device

An electrical connector mountable to a substrate, the substrate having a hold down receiving hole and a plurality of contact receiving holes, the connector comprising:

• a housing having a first end, a second end, and a face;
• a plurality of contacts extending through the housing, each of which has a contact tail that extends beyond the face;
• an alignment device having a first face adjacent the housing, a second face positionable adjacent the substrate, and a plurality of apertures extending between the first face and the second face for receiving a respective contact tail;
• a hold down fastener that extends from the face of the housing at least partially into a receiving aperture of the alignment device;
• and
• a pair of latches that slidably couple the alignment device to the ends of the housing such that the alignment device is selectively disposable along a length of the contact tails between a first position in which the latches hold the alignment device such that distal ends of the contact tails generally extend between the first face of the alignment device and the second face of the alignment device, and a second position in which the latches hold the alignment device such that the contact tails generally extend beyond the second face of the alignment device, such that when the connector is mounted to the substrate, the contact tails enter the contact receiving holes before the hold down fastener engages the hold down receiving hole.
