Plug with unplugging assisting function

Abstract

A plug with an unplugging assisting function comprises a plug body and conductive terminals. A button assembly, two transmission parts and a pushing portion are arranged on the plug body. The button assembly comprises two buttons and a spring, the buttons are symmetrically arranged on two sides of the plug body, the spring is arranged between the upper ends of the two buttons, and the lower end of each button is of sectorial gear structures. Each transmission part is a transmission gear set comprising a gearwheel and a pinion transmitting coaxially, the two transmission parts are respectively correspondingly arranged at the lower ends of the two buttons and are respectively mounted on the plug body through a positioning shaft, sectorial gear structures of the lower ends of the buttons are meshed with the pinions of the corresponding transmission gear sets. The pushing portion is mounted on the outer side of the front end of the plug body and forms a sliding matching relation with the plug body through the outer side and the inner side as well as a guide groove and a guide rack, the inner wall of the pushing portion is provided with a rack structure which is longitudinally disposed and is meshed with the gearwheel of the transmission gear set at the corresponding position, the pushing portion is driven to move back and forth along the plug body by rotation of the gearwheel, the front end of the pushing portion contacts with the surface of a socket. The plug with the unplugging assisting function has the advantages of convenience, quickness, labor saving and safety in unplugging.

Description

Technical field: [0001] The invention relates to a plug for a power supply or a charger, in particular to a plug for a power supply or a charger that can be pulled out safely. Background technique: [0002] The plug and socket of the power supply or charger are widely used in various fields such as industry, agriculture, commerce, and family, and are indispensable devices in modern life and work. But also there are serious deficiencies in the process that plug and socket are used together and are: [0003] 1. Some sockets cannot clamp the metal conductive terminals of the plug due to the poor material or insufficient elasticity of the metal reed, which may easily cause virtual contact, resulting in heating of the contact point between the plug and the socket when using high-power electrical equipment. Burn out and then die, many manufacturers have overcome the above shortcomings through technological innovation and process improvement, but the problem that arises is that wh...

Problems solved by technology

[0003] 1. Some sockets cannot clamp the metal conductive terminals of the plug due to the poor material or insufficient elasticity of the metal reed, which may easily cause virtual contact, resulting in heating of the contact point between the plug and the socket when using high-power electrical equipment. Burn out and then die, many manufacturers have overcome the above shortcomings through technological innovation and process improvement, but the problem that arises is that when the electrical equipment with the plug and socket in close contact is used up and the power plug is to be unplugged But it is very difficult, especially some old people and women can't pull out the plug at all

Sometimes, if the force is too strong, it is easy to pull out the plug and the socket from the wall together and cause the risk of electric shock; or it is easy to lose the center of gravity and fall backward after the plug is pulled out

[0004] 2. When the plug is combined with the mobile socket, when unplugging the plug, you must fix the socket with one hand and pull out the plug with one hand, especially when the mobile socket is at the foot of the wall or under the table, you need to bend over with both hands and work hard, and you cannot operate with one hand , very inconvenient

[0005] 3. In some cases, when the plug is pulled out halfway, it is necessary to temporarily stop changing the force position of the finger and the plug. At this time, the short stop makes the conductive terminal of the plug still live and exposed, and it is easy to cause indirect or direct electric shock between the finger and the conductive terminal.
