A charging circuit for a screwdriver

Abstract

The invention discloses a charging loop of a screwdriver. The screwdriver comprises a metal casing, wherein a bearing seat, a conducting strip and a battery are arranged in the metal casing; a screwdriver accommodating seat comprises an accommodating seat main body, a PCBA (printed circuit board assembly), a cathodic conducting strip and an anodic elastic conducting body; when the screwdriver is connected to a position in the screwdriver accommodating seat in an inserting manner, an outside power supply source is connected with an anodic power supply terminal of the PCBA, the anodic elastic conducting body, the bearing seat, the conducting strip, the anode of the battery, the cathode of the battery, the metal casing, the cathodic conducting strip and a cathodic power supply terminal of the PCBA to form the charging loop. The charging loop of the screwdriver disclosed by the invention has the benefits that the screwdriver and the screwdriver accommodating seat which are matched are adopted, the screwdriver and the screwdriver accommodating seat are connected in the inserting manner so as to form the charging loop, and the screwdriver is convenient and rapid to charge by the charging loop; the anodic elastic conducting body adopts a specific structure, the contact between the anodic elastic conducting body and the screwdriver is more reliable, the accuracy requirements for a conducting component are reduced, and the inserting and the drawing are smoother; an elastic component is added, so that the abutted connection between the conducting strip and the bearing seat is steadier, and the stability of the charging loop is improved.

Description

technical field [0001] The invention relates to a charging circuit, in particular to a charging circuit for a screwdriver. Background technique [0002] A screwdriver is a tool used to twist a screw to force it into place. Generally, screwdrivers are divided into ordinary screwdrivers, combination screwdrivers and electric screwdrivers. [0003] Traditional electric screwdrivers are generally powered by batteries, but battery replacement is inconvenient and the use time is short. [0004] In the prior art, a rechargeable electric screwdriver generally needs a special charging stand, and the charging stand is generally contact or plug-in, and the connection between the contact charging stand and the electric screwdriver is not compact enough and easy to loosen. It is inconvenient to take off and plug in. Contents of the invention [0005] The purpose of the present invention is to solve the above-mentioned technical problems, and propose a charging circuit for a screwdriv...
