Problems solved by technology
Although the above two patents have made improvements to the two-pin plug and the three-pin plug, but because there is no safety protection device, when the user misuses or the child accidentally pokes the metal strip into the jack, it will cause damage to the electrical appliance, or even lead to injury

Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0019] Such as Figure 1 to Figure 7 As shown, the description of the icon number: seat body 1, cover body 2, positioning shaft 21, left limiting column 22, right limiting column 23, torsion spring positioning column 24, left convex body 25, right convex body 26, left protective piece 3. Left limiting groove 31, left positioning groove 32, right protective piece 4, right limiting groove 41, right positioning groove 42, torsion spring 5.
[0020] A power connector with a child protection device, including a matching seat body 1 and a cover body 2. The seat body 1 is equipped with an L-pole conductive insert and an N-pole conductive insert, and is matched with the position of the jack on the cover body 2. It is characterized in that: a positioning shaft 21 is formed in the cavity of the cover body 2, and the positioning shaft 21 penetrates and ...

The invention discloses a power connector with a child protection device, and the power connector comprises a base body and a cover body which are matched for assembly; a positioning shaft is arranged inside a cavity body; the positioning shaft penetrates and is matched with a left protection part and a right protection part in a rotating manner; a torsion spring positioning column is further arranged inside the cavity body of the cover body; the torsion spring positioning column penetrates and is matched with a torsion spring in a rotating manner; and two arms of the torsion spring are respectively connected with the left protection part and the right protection part in a supporting manner. When in normal insertion, diagonal planes which are matched with plugs is formed between the two rotating arms of the left protection part and the right protection part, and the plugs move downwards, simultaneously rotate to the clockwise and the counterclockwise directions, and extrudes and exposes the butt-joint plugs; and when the plugs are pulled out, two torque arms of the torsion spring respectively press a left positioning slot of the left protection part and a right positioning slot of the right protection part, and the left protection part and the right protection part form a parallel connection state in a leaning way after the reset. When a single jack is inserted by a thing and one side of the left protection part or one side of the right protection part bears the force, a middle lever support point below the left protection part or the right protection part forms the lever effect, the left protection part or the right protection part tilts to one side and buckles into a positioning frame so that the left protection part or the right protection part can not rotate, thereby playing the limiting state of non-normal use, further ensuring the electrical safety and preventing the occurrence of accidents.
Description
technical field [0001] The invention relates to the technical field of power connectors, in particular to power connectors with child protection devices. Background technique [0002] The operation of electrical appliances is usually inseparable from the power supply. As a necessary tool for connecting electrical appliances and power supplies, the application technology of power connectors is also constantly improving. Usually, the socket supporting the plug generally has two sockets and three sockets. Therefore, the plug corresponding to the socket is also divided into a two-pin plug and a three-pin plug. The plug effectively solves the technical problems that the existing vertical two-pin power plug is easy to fall off and occupies a large space. Another example is that the Chinese utility model patent with application number 200420047833.5 discloses a convex female socket three-pin plug, including three metal female sockets of ground, fire and zero wire, which are arrang...
