Mobile phone uninterruptible power supply system and elastic switch for same

Abstract

The invention discloses a mobile phone uninterruptible power supply system and an elastic switch for the same. The uninterruptible power supply system comprises a main battery and an auxiliary battery as well as a mobile phone circuit mainboard, wherein the auxiliary battery is formed by a Farad capacitance. A positive electrode and a negative electrode of the auxiliary battery are at least provided with a diode, the electric power in the main battery can flow into the auxiliary battery through the diodes so as to charge the auxiliary battery, and the electric power can be prevented from flowing back to the main battery after the voltage of the main battery is dropped through the diodes. The elastic switch consists of a metal sheet I and a metal sheet II, wherein the metal sheet I has elasticity, one end of the metal sheet I is fixed, the other end of the metal sheet I is riveted with a projection; both ends of the metal sheet II are fixed; the end of the metal sheet I which is riveted with the projection is elastically and electrically connected with one end of the metal sheet II; and when the projection suffers pressure F, the electric connection between the metal sheet I and the metal sheet II is disconnected, and when the pressure F suffered by the projection disappears, the electric connection between the metal sheet I and the metal sheet II is restored.

Description

technical field [0001] The invention relates to a mobile phone component, in particular to an accessory component of a mobile phone power supply. Background technique [0002] The "uninterruptible power supply mobile phone and its use method" announced by the prior art publication number CN101621569, and the "uninterruptible power supply mobile phone battery" announced by the publication number CN2857238 all make the mobile phone Reach the purpose of changing the battery without shutting down the machine. [0003] But in the prior art, no matter increasing the number of batteries or changing the battery power supply circuit, the manufacturing cost of the mobile phone has been excessively increased, and the valuable space inside the mobile phone has been wasted. Contents of the invention [0004] The technical problem to be solved by the invention is to add a farad capacitor to the mobile phone so as to realize the purpose of replacing the battery without shutting down the...
