Description

Mobile phone charger with timing function

【Technical field】

The utility model relates to a charger, in particular to a mobile phone charger.

【Background technique】

The rapid development of information makes mobile phones an indispensable communication tool in people's daily life. After the mobile phone is charged with the mobile phone charger, we often forget to unplug the power plug of the charger from the power supply. In this way, not only The overcharging of the mobile phone will affect the service life of the mobile phone battery and bring potential safety hazards. Moreover, the charger is always plugged into the power supply, and the electronic components of the built-in circuit board of the charger will always be in a power-on state, and will not stop working, consuming power, causing unnecessary Necessary waste.

【Content of invention】

In view of the problems existing in the current known technology, the technical problem to be solved by the utility model is to provide a mobile phone charging time that can be set. After the charging of the mobile phone is completed within the set time, the charger will automatically disconnect from the charging power supply to prevent the mobile phone from overcharging. It is a mobile phone charger with the characteristics of energy saving and safety.

In order to solve the problems of the technologies described above, the utility model is accomplished by taking the following technical solutions:

A mobile phone charger with a timing function, including a power plug, a circuit board and a mobile phone tail plug. The power plug has a plastic shell and two electrode pieces. They are respectively electrically connected to the circuit board, and the feature is that a timer is provided on the connection circuit between the electrode sheet and the circuit board. The timer is a wind-up timer.

The utility model sets a timer on the mobile phone charger. When the mobile phone is charging, we only need to set a suitable charging time for the mobile phone. In this way, after the charging of the mobile phone is completed within the set time, the charger is automatically disconnected from the charging power supply. On, so it completely eliminates the overcharging of the mobile phone and the reactive power consumption of the charger, and has the characteristics of energy saving and safety.

【Description of drawings】

The utility model has following drawings:

Fig. 1 is the structural representation of the utility model

【Detailed ways】

Describe the embodiment of the utility model in detail below in conjunction with accompanying drawing.

As shown in the figure, the utility model comprises a power plug, a wind-up timer 3 (its structure is the same as that used by an electric fan), a circuit board 5 and a mobile phone tail plug 7, and the power plug has a plastic shell 2 and The two left and right electrode sheets 1, the timer 3 and the circuit board 5 are arranged in the plastic shell 2, the rotary switch 4 of the timer is exposed to the plastic shell 2, and the power-on time can be set by adjusting the rotary switch 4, and the timer 3 has The moving contact 10, the static contact 9 and the shifting block 11 (the working principle of the timer is that when the on-time is set, the moving contact 10 is closed with the static contact 9 under the push of the shifting block 11, and the circuit is connected. When the set time is up, the movable contact 10 is due to the recovery of the shifting block 11 and the elasticity of the movable contact 10 itself, the movable and static contacts are separated, and the circuit is cut off), and the left side electrode sheet 1 is directly electrically connected to the circuit board 5 by a lead. Connect, the right side electrode sheet is electrically connected with the moving contact 10 of the timer, the static contact 9 of the timer is electrically connected with the circuit board 5 through the wire 8, and the mobile phone tail plug 7 is connected with the circuit board 5 through the wire 6.
