The utility model content

Main purpose of the present utility model is to overcome above-mentioned shortcoming, and a kind of USB battery of being convenient to assemble positive and negative electrode is provided;

Another purpose of the present utility model is to provide a kind of USB battery that the battery cap and the battery body of USB battery are linked together.

For realizing above-mentioned purpose, USB battery of the present utility model comprises the battery body and the battery cap of cylinder groove shape, be provided with rechargeable cell in the battery body, the metallic elastic body, circuit board, USB male support, USB male sheath body, be provided with USB female sheath body and conduction card in the battery cap, USB male sheath body sheathed with USB male support on, this USB male support be provided with some be used for USB interface in the electrode terminal of electrode conduction, circuit board is provided with the USB battery charger, this charging circuit just, negative input is connected with electrode terminal on the USB male support respectively, conduction card and USB female sheath body are mutually fixedly set, and the card that should conduct electricity is corresponding with the electrode terminal on the USB male support, the battery body of this USB battery and battery cap are the metal material of conduction, and an electrode of the rechargeable cell in the above-mentioned battery body is by metallic elastic body and battery body conducting, the electrode terminal corresponding with the conduction card in another electrode and the USB male support is connected, and this conducts electricity the metal shell conducting of card and battery cap.

This USB battery also comprises an elastic caoutchouc circle, and this elastic caoutchouc circle is fixedlyed connected with battery cap with battery body respectively.

This USB battery also includes a metal spring.

Beneficial effect: USB battery of the present utility model, owing to adopted above-mentioned structure, therefore can be connected battery body with battery cap, and this battery body and battery cap used as electrode respectively, so just can realize rechargeable cell and the battery body of this USB battery and being connected of battery cap easily, thereby can save the welding of electrode in battery body and between the battery body of rechargeable cell, thereby be more convenient for assembling; In addition owing to used flexible rubber ring to connect between the battery body of this USB battery and the battery cap, therefore when charging, can keep still keeping certain connection between this battery cap and the battery body, avoid occurring that battery cap is lost and the situation that can't use.

For making things convenient for the auditor can further understand the utility model is technology, means and the effect that the utility model purpose that reaches predetermined is taked, see also following about detailed description of the present utility model and accompanying drawing, only for reference and the explanation usefulness of the following drawings is not to be used for the utility model is limited.
