Abstract: An electrical connector includes a housing, a number of contacts received in the housing and a spacer for holding the contacts. The housing includes a mating portion and a pair of extensions extending from the mating portion. The pair of extensions and the mating portion jointly form a receiving space to receive the spacer.
