1. Field of the Invention
The present invention relates to an electrical connector, and particularly to a micro electrical connector for mating with a complementary connector.
2. Description of Prior Arts
A normal USB receptacle connector comprises an insulative housing, a shell enclosing the insulative housing and a plurality of contacts received in the insulative housing. Each contact always comprises a tail portion for soldering to an electronic member, such as a motherboard. The tail portions are exposed out of the insulative housing and the shell. However, as the development, the electronic member becomes more and more smaller. Therefore, the interior space between the electrical connector also becomes smaller. Accordingly the effect of the Electro-Magnetic Interference (EMI) to the discovered tail portions is obvious.
Obviously, it is desirable to have an electrical connector has an improved structure.
An object of the present invention is to provide an electrical connector to prevent EMI to the contacts.
To achieve the above object, an electrical connector adaptor for connecting with a complementary connector in a mating direction, comprises a shell, an insulative housing received in the shell and a plurality of contacts received in the housing. The shell comprises a top surface, a pair of lateral surfaces, respectively, connecting with the top surface, and a two-parts rear surface, respectively, bent from the lateral surfaces. The two-part rear surface comprises a base plate and a shielded plate extending rearwardly from the base plate. Each contact comprises a tail portion exposed out of the insulative housing. The shielded plate is above and covers the tail portions of the contacts.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.

Each contact 3 comprises a contacting portion 34, a retaining portion 33 extending downwardly from the contacting portion and a tail portion 32 extending rearwardly from the retaining portion 33. The contacting portions 34 are received in corresponding slots 2221. The retaining portions 33 are insert-molded in the housing 2. The tail portions are exposed out of the housing 2 and located between the slits 216 of the housing. Furthermore, the tail portions are fixed between the restricting tabs 122 of the shell 1 and under the shielded planes 152 of the shell 1. The restricting tabs 122 prevent Electro-Magnetic Interference (EMI) to the tail portions 32 from the lateral direction. The shielded planes 152 prevent EMI to tail portions 32 from the front-to-back direction and an up-to-down direction.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
