Abstract: An electrical connector includes an elongated insulative housing defining a central slot to receive a module therein. A plurality of contacts are provided by two sides of the central slot for mechanical and electrical engagement with the corresponding circuit pads on the module. A pair of platforms are provided adjacent two opposite ends of the housing. A pair of latch devices are provided at two opposite ends of the housing wherein each latch device includes a plastic member and a metal member. The plastic member integrally extends forward from the housing with a locking head proximate the distal free end thereof. The metal member includes a horizontal plate interferentially received within the corresponding platform, and a vertical plate closely positioned by the outer side of the plastic member.
