The shield 300 a of this embodiment is provided with a shielding plate 340 covering the entire side surface of the receptacle 100 and plug 200, further to another aspect of the shielding plate 340 and shielding plate 300 a, increase its strength Reinforcement rib 341 is formed. In the shield plate 300 of the first embodiment described above, the short reinforcing side plate 320 is provided on the side surface, and is not structured to cover the entire side surface of the receptacle 100 and the plug 200. Although an electrical and electromagnetic shielding effect can be obtained even with this, if the entire side surface is covered as in the second embodiment, the shielding effect is further improved, and the influence of electrical and electromagnetic noise is further reduced. It can be further reduced.
Note that the reinforcing rib 341 may have a structure in which the center portion is punched .
