BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] 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
[0002] 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.
[0003] Obviously, it is desirable to have an electrical connector has an improved structure.
SUMMARY OF THE INVENTION
[0004] An object of the present invention is to provide an electrical connector to prevent
EMI to the contacts.
[0005] 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.
[0006] 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] Referring to FIGS. 1 and 2, an electrical connector 100 comprises a shell 1, an insulative
housing received in the shell 1, and a plurality of contacts 3 insert-molded in the
insulative housing 2.
[0012] Still referring to FIGS. 1 and 2, the shell 1 comprises a top surface 11, a bottom
surface 12, a left surface 13, a right surface 14 and a rear surface 15 bent rearwardly
from the left surface 13 and the right surface 14. Above-mentioned surfaces together
define a receiving room (not labeled). The top surface 11, the bottom surface 12,
the left and the right surface 13, 14, respectively, forms a guiding surface for guiding
the complementary connector (not shown). The top surface 11 comprises a resilient
tab 111 bent into the receiving room for resisting the shield (not shown) of the complementary
connector. The top surface 11 comprises a pair of holding portions 112 extending rearwardly
from the opposite ends of a rear edge thereof. The holding portions 112 and the rear
surface 15 together define a receiving space (not labeled). The left surface 13 and
the right surface 14, respectively, forms a positioning tab 121 extending outwardly
therefrom for positioning the electrical connector 100 on the motherboard (not shown)
during soldering. The bottom surface 15 comprises a pair of restricting tabs 122 extending
rearwardly from the opposite ends of a rear edge thereof. The rear surface 15 comprises
a base plane 151 and a shielded plane 152 extending rearwardly from the base plane
151.
[0013] Referring to FIG. 3 and FIG. 4, the insulative housing 2 comprises a main body 21
and a mating portion 22 extending forwardly from the main body 21. The main body 21
comprises a retaining block 212 projecting upwardly therefrom. The retaining block
212 is located between the holding portions 112 of the shell 1 for restricts the movement
in a front-to-back direction of the housing 2. A plurality of blocks 213 are alternatively
formed at a bottom wall 218 of the main body 21 engaging with the bottom surface 12
of the shell 1. A plurality of slits 216, respectively, forms between every two adjacent
blocks 213. A pair of stopping blocks 215 are formed at the opposite ends of the bottom
wall for engaging with the restricting tabs 122 of the shell to restrict the movement
in a lateral direction of the housing 2. A pair of engaging blocks 214 are formed
at the opposite ends of the main body 21 for engaging with the inner surface of the
left and right surface 13, 14 of the shell 1. The mating portion 22 defines a plurality
of receiving slots 2221 thereon.
[0014] 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.
[0015] 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
