Metal terminal rear cover and terminal

Abstract

The invention discloses a metal terminal rear cover and a terminal. The metal terminal rear cover comprises a bottom plate. At least one micro-seam belt is arranged on the bottom plate. A plurality of micro-seams are formed in each micro-seam belt. The micro-seam belts divide the bottom plate into at least two radiation parts. At least one of the radiation parts is used for being connected with a matched circuit and sending electromagnetic waves. The micro-seams are formed in the micro-seam belts, and therefore the proportion of nonmetal parts on the metal terminal rear cover is decreased; the radiation parts are connected with the matched circuit, and therefore electromagnetic waves are radiated; antenna radio frequency is achieved for the metal terminal rear cover, and therefore the antenna radio frequency efficiency is improved, the antenna radio frequency efficiency is improved when the overall appearance requirement of the terminal is ensured, and the effect of improving user experience is achieved.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a metal terminal back cover and a terminal. Background technique [0002] At present, the metal back cover of the mobile phone is usually provided with two plastic isolation strips to separate the metal back cover into three metal parts, so that the radio frequency efficiency of the antenna inside the mobile phone can be improved by utilizing the gap between the metal parts. However, as users have higher and higher requirements for the appearance of mobile phones, the proportion of the metal part of the metal back cover of the mobile phone is required to increase, resulting in a decrease in the proportion of the plastic isolation belt. In this case, as the proportion of the plastic isolation strip decreases, the radio frequency efficiency of the antenna inside the mobile phone will decrease, thereby affecting the user experience of the mobile phone.
