Description

A power adapter with self-cutting power for useless electric equipment

technical field

The utility model belongs to the field of electrical appliances, and relates to a power adapter, in particular to a power adapter for self-cutting off power for useless electric equipment.

Background technique

The power adapter, also known as an external power supply, is a power supply voltage conversion device for small portable electronic devices and electronic appliances. It is commonly found on small electronic products such as mobile phones, liquid crystal displays, and notebook computers. Commonly used power adapters are highly versatile, and usually one power adapter can provide power support for various types of small electronic products.

However, after the power adapter is connected to the power supply, it will still consume electric energy when it is not connected to the electrical equipment, which will not only cause waste of electric energy, but also cause aging of the internal components of the power adapter, posing a safety hazard.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a power adapter with simple structure, convenient use, energy saving, and automatic power-off for useless electric equipment that ensures safe use of electricity.

The utility model solves the problems of the technologies described above by adopting the following technical solutions:

A power adapter for self-cutting power of non-use equipment, including a power adapter body, a safety switch, a conductor and a power plug, two power plugs are inserted in parallel in the power adapter body, and the power adapter A longitudinal fracture is formed on one of the power plugs in the body, and the safety switch is inserted into the longitudinal fracture through the upper side of the power adapter body. The lower end of the safety switch is connected to the conductor, and the conductor is coaxially wound with a A spring, the upper end of the spring is connected to the lower end of the safety switch, the lower end of the spring is fixed on the upper end of the longitudinal fracture of the power plug, the lower end of the conductor is fixed with a metal sheet, and the inner part of the power adapter is set There is an electromagnet, which is connected to the low-voltage end of the power adapter plug, and is vertically spaced from the electric conductor metal sheet of the safety switch.

Advantage and beneficial effect of the present utility model are:

1. The utility model adds a safety switch in the ordinary power adapter, so that the power adapter can cut off the connection between the power adapter and the power supply after the power adapter is kept connected to the power supply, so that the connection Power adapters that are powered but not connected to electrical equipment have no power loss, thereby achieving the purpose of saving energy and using electricity safely.

2. The utility model opens a break on a power plug, utilizes the electromagnet set inside the power adapter to generate electromagnetic attraction after electrification, and attracts conductors to connect to the power plug, thus playing the role of continuous power supply for electrical equipment. When the electrical equipment is pulled out, the electromagnet loses its electromagnetic attraction, and the conductor of the safety switch resets under the action of the spring force, so as to achieve the purpose of cutting off the power supply and protecting the power adapter. It is quick to operate and easy to use.

3. The utility model is simple in structure, easy to manufacture, easy to operate, and low in cost. The structure of the power adapter is cleverly changed through the break and the spring, and the power adapter is cut off after the electrical equipment is pulled out through the cooperation of the electromagnet and the safety switch. At the same time, there is no need to unplug the power adapter from the power supply, which is convenient to use and saves electricity, is safe and environmentally friendly, and is suitable for vigorous promotion and use.

detailed description

The utility model is described in further detail below through specific examples, the following examples are only descriptive, not limiting, and cannot limit the protection scope of the utility model with this.

The utility model relates to a power adapter for self-cutting off power of useless electric equipment. It includes a power adapter body 1 , a safety switch 2 , a spring 3 , a conductor 4 , a power plug 5 and an electromagnet 6 . The two power plugs are inserted in parallel in the power adapter body, and the part of one of the power plugs in the power adapter body forms a longitudinal fracture; the safety switch is inserted in the power adapter body On the upper side, the lower end of the safety switch is connected to the conductor, the conductor is coaxially wound with the spring, the upper end of the spring is connected to the lower end of the safety switch, and the lower end of the spring is fixed on the upper end of the longitudinal fracture of the power plug , the lower end of the conductor is fixed with a metal sheet; the electromagnet is arranged inside the power adapter, the electromagnet is connected to the low-voltage end of the power adapter plug, and is connected to the conductor of the safety switch Metal sheets are set at vertical intervals.

Working principle of the utility model:

The utility model adds a safety switch on the main body of the power adapter, the safety switch is connected to the conductor through a spring, and the spring is in a non-stressed state under normal conditions. After the power adapter is connected to the power supply and connected to the electrical equipment, the safety switch is pressed so that the conductor is inserted into the longitudinal opening of the power plug. The power supply of the power adapter is turned on, and the low-voltage side of the adapter flows through the current when it is connected to the electrical equipment. At this time, the electromagnet set in the power adapter introduces the low-voltage end current to charge, and absorbs the metal sheet at the bottom of the conductor. At this time, even if no external force is applied to the safety switch, the power plug is still in the conduction state, and the adapter can work normally. Electrical equipment continues to be powered.

When the electrical equipment is unplugged, the current at the low-voltage end of the power adapter disappears, the electromagnet loses its magnetism, the spring recovers its deformation, the safety switch pops up and returns to its original position, and the circuit between the power adapter and the power supply is disconnected to form an open circuit state. At this time, the power adapter has no power. Loss occurs, so as to achieve the purpose of saving energy and using electricity safely. In this device, except for the contact surface between the conductor and the adapter plug, other parts are insulated.
