The use of the micro-slit tape is provided with a plurality of micro-slits, thereby reducing the proportion of the non-metallic part of the metal terminal cover; And the use of at least one radiation portion connected to the matching circuit to achieve radiated electromagnetic waves; Thus the metal terminal cover itself to achieve antenna RF, thereby improving the antenna RF efficiency, and then in order to ensure the overall appearance of the terminal requirements, but also improve the antenna RF efficiency, to achieve the effect of improving the user experience.

The invention relates to a stripper ejector mechanism which comprises a stripper and an integrated insert. The integrated insert comprises a mold core at the upper part and a fixed plate connected with the mold core and positioned at the lower part. The mold core at the upper part of the integrated insert is matched with the stripper. A cooling water passage is arranged on the stripper. A cooling water passage is arranged on the integrated insert. The mold core and the fixed plate are integrated into the integrated insert, so that the problem that the strength of the mold core is influenced due to a gap between the stripper and the mold core of a conventional die, so that the thickness of a product is nonuniform is solved, the requirement on the appearance of the product is ensured and the form of the stripper ejector mechanism is also ensured.

A mobile phone shell and its processing method are provided. The mobile phone shell comprises an outer shell (1) formed by metal punching, forging or injection molding, and inserts (21,22) are welded or concave structures are formed on the inner side of the outer shell. The mobile phone shell also comprises an inner shell (3) molded on the inner side of the outer shell by metal pressure casting, and the inner shell surrounds the inserts or fills into the concave structures so as to combine the outer shell with the inner shell. The processing method includes following steps: forming the outer shell by metal punching, forging or injection molding; soldering the inserts or forming the concave structures on the inner side of the outer shell; putting the outer shell into a mould and pressure casting the inner shell in the inner side of the outer shell. The method ensures the appearance requirement of the mobile phone shell, as well as reduces processing amount of cutting process, which reduces the cost of mobile phone shell largely.

The invention discloses an automobile oil filler cap hinge module which comprises an oil filler cap hinge (1), a hinge seat (2), a rotating shaft (3) and a hinge spring (4), wherein the oil filler cap hinge (1) is articulated with the hinge seat (2) by the rotating shaft (3) which is penetrated with the hinge spring (4); and a welding locating hole (12a) is welded on the oil filler cap hinge (1).The automobile oil filler cap hinge module is characterized in that mounting holes (2a) on the hinge seat (2) are strip-shaped; at least one of the welding locating holes (12a) on the oil filler cap hinge (1) is strip-shaped; and the axes in length direction of the strip-shaped holes are all parallel to the axis of the oil filler cap hinge (1). The automobile oil filler cap hinge module can conveniently adjust the matching clearance difference of an oil filler cap assembly and a side-wall shell plate hole, is convenient for adjusting the surface difference of an oil filler cap and a side-wallshell plate, improves production efficiency, and is easy to ensure the appearance of the automobile body at the oil filler.
