Abstract
Abstract An electrical connector includes a front shielding shell member, a front housing member, a number of contacts, a rear housing member and a rear shielding shell member. The contacts are mounted to two sides of the rear housing member to prevent the contacts from moving sideward and to and fro. The rear housing member with the contacts is then inserted into a cavity defined in the front housing member to fixedly connect therewith, whereby contact portions of the contacts extend into contact passageways defined in the front housing member and are further prevented from moving upward and downward, whereby the contacts and the front and rear housing members are all fixedly connected. Finally, the front shielding shell member is mounted to the front housing member and the rear shielding shell member is connected to the front shielding shell member to accomplish the assembly of the electrical connector.
