Certainly, in other implementation manners, only one of the first fixing arm 411 and the second fixing arm 421 may also be included.

In addition, the types of the electrical connector 100 of the present invention are not limited to the ones described above, and may also include DisplayPort socket connectors and the like. Those skilled in the art can understand that any electrical connector of this type with the tongue plate 11 and the metal shielding shell 3 can adopt the idea of the present invention for corresponding improvement.

Compared with the prior art, the present invention shortens the length of the metal shielding shell 3 along the insertion direction A, so that the metal shielding shell 3 will not be obviously distorted after being installed in the equipment shell 200 The exterior of the device housing 200 is viewed. Please refer to FIG. 1 , FIG. 14 and FIG. 27 , the inner surface 523 of the extension protrusion 52 can be clearly observed from the outside of the device casing 200 , which is beneficial to improve the aesthetics. In addition, although the length of the metal shielding shell 3 is shortened, the shielding effect is improved by setting the metal fixed shell 4 supported on the equipment shell 200; the metal fixed shell 4 is compared with the metal The shielding shell 3 expands outwards, thereby making the metal fixed shell 4 deviate outward from the receiving space 30. On the one hand, this is beneficial to increase the shielding area; on the other hand, it is also beneficial to avoid the metal fixed shell 4. The casing 4 is viewed from the outside of the device casing 200, improving aesthetics.

The above embodiments are only used to illustrate the present invention rather than limit the technical solutions described in the present invention. The understanding of the present invention should be based on those skilled in the art, although this specification has described the present invention in detail with reference to the above embodiments. Note, however, those of ordinary skill in the art should understand that those skilled in the art can still modify the present invention or replace it equivalently, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the within the scope of the claims of the present invention.
