At this time, the side fixing tabs 114 correspondingly extend from the two side faces surrounding the casing 11 ,, and extend out of the shielding casing 1 at a height position of the electric plate 11 m334523. The fixing tab 121 is also correspondingly extended from the terminal portion housing 120 of the height reducing circuit board. The above preferred embodiments are described by taking the Mien) female socket as an example, but the creation is not limited thereto. In the following patent scope, the electrical connection g of this creation can be modified and applied to the female socket of various specifications of the electrical connector 'for example, general, mini or micro universal serial bus (USB, Mini USB, 〇r Micr〇 removes the female socket of the specification electrical connector's or other female connector of similar structure. It can be seen from the above preferred embodiment of the present invention that the application of the present invention has the following advantages: 1. The electrical connector of the present invention can shield the opening portion of the conventional terminal for extending the terminal by the terminal portion housing, thereby improving electromagnetic and other impurities. The shielding effect of the signal 2, whether it is the board surface configuration or the sinking board type electrical connector, can use the design of the terminal part shell of the original electrical connector to achieve the shielding effect of improving electromagnetic and other noise. 3. The electrical connector of the present invention can fix the terminal portion of the electrical connector to the circuit board by fixing the tabs of the terminal housing, thereby making up for the deficiency of the conventional technology. , to increase the stability of the electrical connector when assembled on the circuit board. Although the present invention has been disclosed in a preferred embodiment as above, it is not intended to limit the present invention, and any person skilled in the art can make various changes and refinements without departing from the spirit and scope of the present invention. The scope of the creation of the thinning is subject to the definition of the scope of the patent application. 12 M334523 [Simple Description of the Drawings] In order to make the above and other objects and features of the present invention more comprehensible, the detailed description of the drawings is as follows.
