Abstract

The invention discloses a locked fixing structure, an insulating sleeve and an electronic device applying the locked fixing structure. The locked fixing structure is configured to a fixing part and comprises an insulating sleeve and a stop nut, wherein the insulating sleeve comprises a hollow cylinder, a first stop platform and a lug; the hollow cylinder is positioned in a perforation of the fixing part; the first stop platform protrudes out of the side edge of the hollow cylinder and is contacted with the fixing part; the lug is configured to a horizontal surface of the first stop platform so as to form a second stop platform; the stop nut is configured in the hollow cylinder; the top of the stop nut is provided with a flange; and the flange is pressed against the horizontal surface of the first stop platform and is contacted with the second stop platform.

Description

technical field [0001] The invention relates to a locking and fixing structure, and in particular to a locking and fixing structure, an insulating sleeve and an electronic device using the same, which can avoid rotation caused by locking and twisting. Background technique [0002] In today's smart phones, in order to improve the appearance texture, metal shells with better luster are often used. The metal shell is usually locked on the fixed structure with a screw, and surrounds the antenna component, which often causes the antenna to be locked by the metal screw in the area covered by the fixed structure and the metal shell. The impact of the connection causes the antenna radiation to be offset by the interconnected metal structures and greatly attenuated, thereby reducing the antenna performance. [0003] In order to overcome this problem, it is necessary to cut off the communication between the locking and fixing structure and the metal shell to avoid significant attenua...
