An electrical connector comprises a contact having a wire connection member and a mating contact receiving end. The mating contact receiving end includes an abutment edge and an inclined portion. A housing has a contact receiving opening with a contact receiving end. The housing has a projection extending into the contact receiving opening and a first bevelled surface opposing the projection. The first bevelled surface is arranged closer to the contact receiving end than the projection. The inclined portion engages the first bevelled surface to bias the abutment edge into the projection when the contact is incorrectly inserted into the contact receiving opening.
