Electrical header with improved post retention

摘要

An electrical header comprises a dielectric housing having cavities and contact posts held in the cavities. The contact posts extend beyond a first face of the housing for attachment to a substrate and extend beyond a second face of the housing for engagement with contacts of a mating electrical connector. Each of the contact posts has an enlargement in a vicinity of the second face. Each of the enlargements has a width which is greater than a width of its corresponding cavity for preventing the housing from being pulled off of the contact posts when the contact posts are attached to the substrate.
