Overall mains charger is formed to transformer box.Because the mains charger use of notebook computer is extremely frequent, plus it
Stress point concentrates on the junction of power line and transformer box again, the connection of power line and transformer box easily occurs using long
Place loosens, and causes the appearance of loose contact situation occur, both uses to notebook computer impact, and also reduce power supply
The service life of charger.Therefore.Design it is a can effectively improve connective stability, and service life can be effectively improved
Laptop electric power charger is research purpose of the present utility model.
Utility model content
For in place of above-mentioned the shortcomings of the prior art, the utility model is to provide a kind of power supply of notebook computer
Charger, the mains charger of the notebook computer can effectively improve connective stability, and can effectively improve service life.
The technical solution of the utility model is：
A kind of mains charger of notebook computer, the power line comprising incoming transport power supply and square transformer box,
One end of the power line is provided with corresponding plug, and the other end of power line is detachably attached to the transformer box, described
One end that transformer box is not attached to the power line is connected with electricity for accessing notebook computer by corresponding output line
Source export head, the transformer box are internally provided with corresponding potential device and control circuit, the transformer box and the electricity
The connection end side of source line is provided with corresponding connecting hole, and the connection end of the power line and the transformer box is provided with and institute
The corresponding connector of connecting hole is stated, one is connected with the connector can entangle the square locating cover of the transformer box, institute
State the connector that power line is provided with by it and insert the connecting hole realization connection that the transformer box is provided with, it is described square fixed
The position enclosure enters on the square transformer box；One layer of corresponding cushion is provided with the square locating cover.
The cushion is one kind in elastomeric material layer or bed of cloth.
The upper surface of the transformer box is provided with the power supply indicator of instruction on/off, the power supply indicator connection
Control circuit inside to transformer box.
The advantages of the utility model：
From the above：One is connected with connector of the present utility model can entangle the square positioning of the transformer box
Cover, the connecting hole that the connector insertion transformer box that power line is provided with by it is provided with realize connection.Now, square positioning
Cover will be inserted on square transformer box, effectively improve lifting surface area, it is ensured that the stability of junction, improve the utility model
The usability life-span.The utility model is provided with one layer of corresponding cushion in square locating cover, improves cushion and improves company
Flexibility when connecing, while part external force can be also eliminated, it further ensure that the stability of junction.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
For the ease of it will be appreciated by those skilled in the art that existing make embodiment combination accompanying drawing into one to structure of the present utility model
Step is described in detail：
With reference to figure 1, a kind of mains charger of notebook computer, the power line 1 comprising incoming transport power supply and square
Transformer box 2, one end of the power line 1 are provided with corresponding plug 3, and the other end of power line 1 is detachably attached to described
