Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a child safety plug, which aims to solve the lack of protection measures for plugs in the prior art against children's misplugging of electrical appliances. The two-pole plug is basically composed of an insulating body, two plugs and a power cord. Insert pins, which may lead to electric shock, and cannot fundamentally prevent safety accidents caused by children plugging in electrical appliances by mistake

Embodiment 1

[0024] An insulating rubber layer 4 is installed on the outer pin 112 and the working pin 2 , and the distance between the insulating rubber layer 4 and the top of the inner pin 112 and the working pin 2 is 3mm-10mm.

[0025] The first gear 13 and the second gear 14 are meshed, and the first gear 13 and the second gear 14 have the same size.

[0026] The unstressed length of the spring 15 is greater than the maximum thickness of the housing 3 , the minimum length of the spring 15 is less than the minimum thickness after the meshing of the first gear 13 and the second gear 14 , and the diameter of the spring 15 is greater than the diameter of the inner pin 111 .

[0027] The height of the inner insertion pin 111 is less than the minimum thickness of the first gear 13 after meshing with the second gear 14 plus the height of the rotation button 16 .

[0028] The insulating sleeve 17 has grid-shaped anti-slip lines.

[0029] The diameter of the rotary button 16 is 8mm-20mm, and t...

Embodiment 2

[0032] The difference between this embodiment and the embodiment is that there is a rectangular groove on the insulating sleeve 17 .

[0033] Working process of the present invention:

[0034] In the working process of a child safety plug of the present invention, press and hold the rotation button 16 when it needs to be used, and release it after rotating 90 degrees, and it can be used normally. Under normal conditions, the rotation pin of the plug is horizontal and cannot be inserted into the socket. When in use, press and hold the rotation button and rotate to turn the pin to the vertical direction and insert it into the socket for use. The structure of pressing and rotating can effectively prevent children from accidentally touching and inserting, reducing hidden dangers of electricity consumption. At the same time, the pin is also equipped with The insulating rubber sleeve only exposes the metal parts at the contact part, which effectively reduces the probability of elect...

Abstract

The invention discloses a children safety plug. The safety plug comprises a rotary contact pin, a working contact pin and a shell, wherein the rotary contact pin is connected with the shell, and the working contact pin is connected with the shell. The structure is reasonable, in a normal state, the rotary pin of the plug is transverse and can not be inserted into a socket, when an adult needs to use the device, a rotary button is pressed to rotate, the pin can be made to rotate to the vertical direction, the plug is inserted into the socket for use, mistaken touch and mistaken insertion by children can be effectively prevented through pressing the rotary structure, hidden dangers of electricity utilization are reduced, the pin is further provided with an insulating rubber sleeve, a metal part is exposed only at a contact part, the occurrence probability of electric shock accidents is effectively reduced, anti-skid lines are arranged at edge recess of the shell, and a safety coefficientis increased.

Description

technical field [0001] The invention relates to the technical field of plugs, in particular to a child safety plug. Background technique [0002] The connectors of general electronic products and the pins of electrical appliances are called plugs. Household AC power plugs and sockets have rod-like or copper-plate-shaped protruding male connectors that physically insert into female connector-type power outlets with slots or recesses. The size is an important technical requirement related to whether the plug, socket and converter can be used safely and whether they meet the general interchangeability requirements to avoid mis-insertion. If the size is unqualified, it will affect the user's use or cause hidden dangers such as poor contact and wrong insertion. If it is light, it will damage the equipment, and if it is serious, it will cause fire and electric shock. [0003] The existing plugs have insufficient protection measures against children misplugging electrical applian...
