Abstract
The utility model relates to a free-capacity-increasing mobile power supply. The power supply comprises a main body and an auxiliary body. Cell boxes are arranged in the main body and the auxiliary body. Contact sheets are fixed to two ends of each cell box. The main body and the auxiliary body are electrically connected through the contact sheets. a first magnet is fixed to a sidewall of the main body which is connected with the auxiliary body. A second magnet which attracts the first magnet is fixed to a sidewall of the auxiliary body which is connected to the main body. The first magnet is fixed to a sidewall of the auxiliary body, wherein the sidewall of the auxiliary body is far away from the main body. The power supply has the following advantages that because cells in the main body and the auxiliary body are connected in parallel, quantities of the auxiliary body can be increased without restriction; therefore, a cell capacity in the main body can be set to be small so that the weight of the power supply can be reduced; when the cell in the main body runs out, one or more auxiliary bodies can be connected according to an actual situation; the auxiliary body which does not use does not need to be carries so that usage is convenient.
Description
Technical field
The utility model relates to a kind of free increase-volume portable power source, belongs to technical field of electronic products.
Background technology
Therefore along with the universal use of large-screen, multinuclear mobile phone, the flying power of mobile phone worse and worse, can be carried more and more extensive that portable power source into mobile phone charging uses.But all there is following shortcoming in current portable power source: its lithium battery is fixed on the inside of portable power source, non-dismountable, and because current portable power source capacity is larger, weight is heavier, and it is quite inconvenient that each out using all needs to carry whole power supply.
Utility model content
The purpose of this utility model is in order to overcome the shortcoming of prior art, the free increase-volume portable power source that provides a kind of and be convenient for carrying, use.
For realizing utility model object, the technical solution adopted in the utility model is:
Free increase-volume portable power source, it is characterized in that: comprise main body and accessory body, in described main body and described accessory body, be provided with battery case, the two ends of described battery case are all fixed with contact, on described contact, be shaped with the first contact for contacting with battery positive/negative, described main body and described accessory body are electrically connected to by described contact, the side that described body interior is positioned at battery case is provided with circuit board, on the sidewall that described main body is connected with accessory body, be fixed with the first magnet, described main body is provided with USB output interface and charging input interface away from a side of described accessory body, described USB output interface and described charging input interface are all electrically connected to described circuit board, the sidewall that described accessory body is connected with described main body is fixed with the second magnet of inhaling mutually with described the first magnet, described accessory body is fixed with the first magnet away from the sidewall of described main body.
As the further optimization to technique scheme, on described contact, be also shaped with the second contact and the 3rd contact, the sidewall of main body is exposed in the 3rd contact of described body interior contact, the second contact of the inner contact of described accessory body and the sidewall that accessory body is all exposed in the 3rd contact, described main body contacts with the 3rd contact by the second contact on described contact with described accessory body to realize and is electrically connected to.
The beneficial effects of the utility model: because the battery in main body and accessory body is for being connected in parallel, therefore can unrestrictedly increase accessory body quantity, what the battery capacity in main body can arrange like this is less, has alleviated the weight of power supply.After battery electric quantity in main body is used up, can select connect one or more accessory body according to actual conditions, obsolete accessory body can be carried, therefore, use all more convenient.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
