Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 1 to FIG. 6 , the first embodiment of the present invention includes a cage 1 , a front frame member 2 and a plurality of elastic pieces 3 .

The cage 1 is made of a metal plate and has a top wall 11, a bottom wall 12 and two side walls 13 which are spaced apart from each other and which are respectively connected to the top wall 11 and the two sides of the bottom wall 12. The top wall 11, the bottom wall 12 and the two side walls 13 together define a plug-in space 14 and a front end of the cage body 1 for accessing the The socket 15 of the space 14 is inserted.

The front frame member 2 is integrally formed from a metal plate and sleeved on the cage The outer side of the front end of the 1 has a seamless frame portion 21, a seamless extension ring portion 22, and two locking tab portions 23. The frame plate portion 21 is erected and has an opening 211. The extension ring portion 22 is defined by the frame plate portion 21 and defines an inner circumferential edge of the opening 211 extending integrally rearwardly and sleeved on an outer side surface of the front end of the cage body 1. The two locking tab portions 23 respectively extend rearwardly from the two side edges of the two side walls 13 by the position of the extension ring portion 22 and respectively have a button hole 231. Each of the side walls 13 of the cage body 1 is provided with two fastening portions 16 that are spaced apart from the corresponding fastening holes 231. The two fastening portions 16 are respectively located on the upper and lower sides of the corresponding fastening holes 231 to fasten the fastening portion. Front frame 2. Further, the top wall 11 and the bottom wall 12 of the cage 1 are respectively provided with two stopper portions 17 for blocking the extension ring portion 22 of the front frame member 2. Specifically, in the embodiment, the fastening holes 231 of the two locking pieces 23 are elongated in the up-and-down direction, and the two fastening portions 16 on each side wall 13 are respectively in the shape of a tab from the side wall. The wall body 13 extends obliquely rearwardly toward the outside of the insertion space 14 and respectively abuts the upper and lower inner edges of the fastening hole 231 by the corresponding locking piece portion 23, thereby forming two fastening fulcrums. The locking piece portion 23 and the two fastening portions 16 are not swayed relative to each other, thereby achieving a firm fastening effect and providing a better holding force. Further, it is assumed that a single elongated buckle portion is engaged with the elongated buckle hole 231 of the present embodiment. In contrast, the two upper and lower spaced buckle portions 16 of the present embodiment can further reduce the locking tab portion 23. Deformation and resistance during assembly. In addition, the upper side edge and the lower side edge of the extension ring portion 22 respectively form two notches 221 corresponding to the stopper portions 17 of the cage body 1, and the stopper portions 17 are respectively in the shape of a lug from the top wall 11 and the bottom. Wall 12 The wall body extends integrally and protrudes laterally from the outside of the wall body and is located in the corresponding notch 221 to define the inner edge of the notch 221 against the extension ring portion 22, thereby combining the front frame member 2 with the cage body 1. And relative positioning is more stable. In the present embodiment, although there are two stopper portions 17 provided on the top wall 11 and the bottom wall 12, respectively, only one of them may be implemented. Of course, the notch 221 of the extension ring portion 22 corresponds to the stopper portion 17 and Adjustment. The effect of electromagnetic shielding of the shield cover 100 at the front end portion can be increased by the outer surface of the front end of the cage 1 by the seamless extension ring portion 22.

The elastic pieces 3 are respectively disposed on the top wall 11 and the bottom wall 12 of the cage 1. And two side walls 13 and surrounding the socket 15 for holding the docking device (not shown).

Referring to FIG. 7 and FIG. 8, the second implementation of the novel shield 100 The example is substantially the same as the first embodiment. However, in the second embodiment, the two side edges of the extension ring portion 22 are respectively formed with two grooves extending in the front and rear directions of the corresponding locking piece portion 23 and extending in the front-rear direction. 222, thereby increasing the elasticity of the locking piece portion 23 to the outside.

Referring to FIG. 9 and FIG. 10, the third embodiment of the novel shield 100 The embodiment is substantially the same as the first embodiment, except that in the third embodiment, the front frame member 2 has a seamless frame portion 21, two locking piece portions 23 and two stop pieces 24, which The frame plate portion 21 is the same as the frame plate portion 21 of the first embodiment, and the two locking piece portions 23 are respectively defined by the frame plate portion 21 and the positions are opposite to the inner edges of the two side walls 13 and extend rearward. Each of the two retaining tab portions 24 is defined by the frame plate portion 21 and the upper and lower inner edges of the opening 211 extend rearward, and respectively form two corresponding cages 1 The notch 221 of the stopper portion 17. The action of the fastening hole 231 of the locking piece portion 23 of the third embodiment and the fastening portion 16 of the cage 1 is the same as that of the first embodiment, and the notch 221 of the stopper piece portion 24 and the stopper portion 17 of the cage body 1 The action relationship is the same as that of the first embodiment, and will not be repeated here.

In summary, the seamless extension ring portion 22 by the front frame member 2 The outer side surface of the front end of the cage 1 can increase the electromagnetic shielding effect of the shield cover 100 at the front end portion. Furthermore, the fastening holes 231 of each of the locking piece portions 23 are engaged with the two upper and lower fastening portions 16 of the side wall 13 of the cage 1 to form two fastening fulcrums, thereby making the locking pieces The portion 23 and the two fastening portions 16 do not sway relative to each other, and the two upper and lower spaced portions 16 can reduce the deformation and resistance of the locking piece portion 23 during assembly, thereby achieving a stable fastening effect and providing better performance. Retentivity.

However, the above is only an embodiment of the present invention, when The scope of the novel implementation is not limited thereto, that is, the simple equivalent changes and modifications made by the present invention in the scope of the patent application and the contents of the patent specification are still within the scope of the present patent.
