The present invention generally relates to a connector, and more particularly to an electrical connector.

2. The Related Art

With the development of electronic products, a variety of the electronic products are connected with peripheral devices more and more frequently. The electronic products are usually connected with the peripheral devices by electrical connectors.

A conventional electrical connector includes an insulating housing, a plurality of terminals and a shielding shell. The terminals are integrally molded to the insulating housing. The shielding shell surrounds the insulating housing. The shielding shell has a top plate, two lateral plates extended downward from two opposite sides of the top plate, a bottom plate connected between bottom edges of the two lateral plates, and a rear plate bent downward from a rear edge of the top plate. The top plate, the two lateral plates, the bottom plate and the rear plate surround a receiving space thereamong. The insulating housing together with the terminals is received in the receiving space.

However, assembling procedures of the conventional electrical connector are generally complex, and the electrical connector is connected with a butting connector unstably. As a result, transmission signals between the conventional electrical connector and the butting connector are affected.

Thus, in order to effectively overcome the aforesaid drawbacks, an innovative electrical connector which has a reasonable-designed structure need be developped, the innovative electrical connector is capable of simplifying assembling procedures of the innovative electrical connector and making electrical connector connected with the butting connector stably.
