Mirror polishing method of mobile phone USB slot panel and mobile phone USB slot component

Abstract

The invention relates to a mirror polishing method of a mobile phone USB slot panel and a mobile phone USB slot component. The polishing method comprises the following steps: (1), punching to form the mobile phone USB slot component, (2), grinding the mobile phone USB slot panel to form a surface with mirror effect, (2.1), laying the ground mobile phone USB slot panel on a smooth grinding disc or a jig, ensuring that the grinding disc rotates anticlockwise and the jig drives a grinding work piece to rotate clockwise, adding rough grinding composition during rotation, performing relative operation friction through the rough grinding composition permeating the part between the grinding work piece and the grinding disc, and cutting the surface of the mobile phone USB slot panel through sand grains of the rough grinding composition, and (2.2), adding finish grinding composition, and repairing the surface of the mobile phone USB slot panel through sand grains of the finish grinding composition. The mobile phone USB slot component comprises the closed and annular slot panel matched with the shape of a USB plug, a slot wall vertically extending along the inner side of the slot panel, and a plurality of arm braces respectively, symmetrically and convexly arranged on the edge of the slot wall.

Description

technical field [0001] The invention relates to a mirror grinding method for a mobile phone USB slot panel and a mobile phone USB slot component. Background technique [0002] CN201020294752.0 announced "a mobile phone with a USB interface". Its purpose is to provide a USB plug connected to the mobile phone body through the connecting seat as a whole, so as to avoid poor contact of the mobile phone caused by stretching the USB cable. At the same time, the fixed shaft in the connection seat is a rectangular column, which can ensure that the USB connector is in a fastened state with the mobile phone body when rotating, and improves the stability of the USB use of the mobile phone. It has a USB interface. mobile phone. The technical solution: the mobile phone with a USB interface includes a mobile phone body (1), a mobile phone main circuit board installed in the mobile phone body (1), and a card slot (3) is also arranged on the mobile phone body (1) , the card slot (3) is p...

Problems solved by technology

Its weak point is: USB card is in the back cover of mobile phone, has caused mobile phone outward appearance not exquisite, and the USB of mobile phone is exposed at the back of mobile phone, and hand sweat or water are easy to enter mobile phone inside from USB interface when mobile phone is held in hand, cause The PCB board of the mobile phone is short-circuited and the entire mobile phone is scrapped

Its weak point is: after the USB plug is embedded in the card slot, the appearance of the mobile phone is not exquisite, and the USB of the mobile phone is exposed at the back of the mobile phone. The PCB board is short-circuited and the entire phone is scrapped

[0005] ⑴The USB plug makes the user more cumbersome when using USB;

[0006] ⑵The USB plug increases the cost;

[0007] ⑶The USB plug is made of plastic painting process. After a period of time, the entire USB plug will be painted off, which leads to the inconsistency between the position of the USB plug and the color of other parts of the mobile phone, which affects the product image.
