The invention relates to a shielding element and an electrical connector plug using the same. The shielding element comprises a shielding sleeve and a clamping sleeve, wherein the clamping sleeve is used for clamping a shielding layer of a cable, and is conductively connected with the shielding layer of the cable; cable channels communicated with each other are formed on the shielding sleeve and the clamping sleeve; the front end of the shielding sleeve is provided with a contact part for conductively connecting an electrical connector shell; the clamping sleeve comprises a permanent seat integrally connected to the rear end of the shielding sleeve and a pressing plate for buckling with the permanent seat to clamp the shielding layer of the cable inserted into the cable channels; and a tile-shaped concave surface is formed on at least one of the pressing plate and the permanent seat. The shielding element provided by the invention can be sleeved to the tail end of an electrical connector, conductively connected with the shielding layer of the cable by the clamping sleeve and conductively connected with the electrical connector shell by the shielding sleeve, so the shielding layer of the cable can be effectively connected by the electrical connector shell and prevented from shielding failure at the wiring position of the electrical connector, thereby effectively solving the problem that the conventional electrical connector cannot prevent lightning.

The invention discloses a chair facilitating storage of objects. The chair facilitating storage of the objects comprises a chair back, a seat plate and supporting legs connected with the seat plate. One side of the upper surface of the seat plate is provided with a mounting block, and the mounting block is movably connected with an overturning supporting plate through a rotating shaft; mounting grooves are formed in the upper surface of the overturning supporting plate, and overturning lateral supporting legs are hinged to the insides of the mounting grooves; the overturning lateral supportinglegs are connected with the inner walls of the mounting grooves through clamping mechanisms; and the lower surface of the overturning supporting plate is provided with an accommodating groove, and two ends of the accommodating groove are hinged t lateral protecting plates through positioning and hinging mechanisms. Articles such as a carry-on bag and a book can be placed in the chair to prevent accidental loss of the articles.

The invention relates to an exhibition device. The exhibition device comprises a display mechanism which comprises a display screen for playing product information; and a display table which comprisesa first folding piece and a second folding piece which are connected in a folding mode, wherein the display screen is rotatably connected with the first folding piece, and the second folding piece isused for bearing a product; after the first folding piece and the second folding piece are completely folded, the display screen is clamped between the first folding piece and the second folding piece; when the first folding piece and the second folding piece are completely unfolded, the display screen can rotate and incline relative to the first folding piece to form a set included angle. The display screen is rotated to an inclined state relative to the first folding piece, so that the display screen displays product information at a proper angle, and the use convenience of the exhibition device is ensured; and when the display screen stops being used, the display screen is rotated so as to be clamped between the first folding piece and the second folding piece which are completely folded, and finally the carrying and storing convenience of the folded exhibition device is improved.
