Electrical connector having hold down member

An electrical connector comprising:

• a dielectric connector housing including a housing body, the housing defining a channel that extends into the housing body;
• a plurality of electrical contacts supported by the housing body such that the electrical contacts define respective mating portions and mounting portions opposite the mating portions, wherein the mating portions are configured to mate with complementary electrical contacts of a complementary electrical component, and the mounting portions are configured to be placed in electrical communication with a substrate when the electrical connector is mounted to the substrate;
• and
• a hold down member including a hold down body and at least one aperture that extends at least into the hold down body, wherein the hold down member is slidably disposed in the channel between a first position whereby the aperture is out of alignment with a complementary aperture in the substrate, and a second position whereby the aperture is in alignment with the complementary aperture,
• wherein when the hold down member is in the second position, at least one fastener is insertable through the aperture in the substrate and into the at least one aperture of the hold down member so as to secure the connector housing to the substrate.
