This invention relates to a secondary cell, particularly relating to one made by using PCB (Printed Circuit Board) fabrication processes and equipped with an electrical connection interface.
The conventional secondary cells, such as Lithium rechargeable cells and Ni—H rechargeable cells, all adopt metal packaging casings, into which elements for constructing the rechargeable cell, including the positive pole, negative pole, insulation film and electrolyte substance, are packed. The conventional secondary cells are mostly individually packed, such that more than one type of conventional secondary cells are to be connected in series or parallel, a cell housing is needed or wires are adopted to weld them together, which are then subsequently packed together by means of a packaging material. When more than one conventional secondary cell is to be connected in series or parallel, regardless of whether the cell housing or wire welding means is adopted, the conventional secondary cells that are connected together doubtlessly result in a relatively large volume.
In view of the difficulties involved in incorporating more than one conventional secondary cell, a secondary cell device having connection interface is developed so as to allow easy incorporation of plural secondary cell devices in use.
It is a first object of this invention to provide a secondary cell device made by PCB fabrication processes, where more and more such secondary cell devices can be easily connected to each other.
It is a second object of this invention to provide a secondary cell device made by PCB fabrication processes, where such secondary cell devices can easily meet the needs of modularization.
To achieve the objects of this invention, this invention provides a secondary cell device having a connection interface, including: a PCB; plural secondary cell units provided on the PCB, wherein the secondary cell units are made of part of the PCB material; an electrical connection interface provided on the PCB and forming electrical connection with the secondary cell units, and at least serving as an output terminal for power generated by the secondary cell units.
These and other modifications and advantages will become even more apparent from the following detained description of a preferred embodiment of the invention and from the drawings in which:
This invention discloses a secondary cell device having connection interface 10, including: plural secondary cell units 101; and particularly an electrical connection interface 103, where the electrical connection interface 103 of the plural secondary cell devices 10 are connected to each other. This invention is able to integrate power generated by plural secondary cell devices 10 in a flexible manner so as to construct a power supply. Furthermore, the electrical connection interface 103 of the secondary cell devices 10 is also an output terminal or input terminal of control signals, which serves as a communication channel in the power management of the secondary cell devices 10.
The electrical connection interface 103 is provided on the PCB 105 and forms the electrical connection of the secondary cell units 101. One function of the electrical connection interface 103 is to serve as the output terminals of the power generated by the secondary cell units 101.
Of course, the electrical connection interface 103 may implement a gold finger, a female type connector, a male type connector, a miniature electrical connector, or any other suitable forms of electrical connectors.
Such electrical connectors 201 serve to connect to the respective electrical connection interface 103 of the secondary cell devices 10. The electrical connectors 201 may implement an electrical connector adapted to the configuration of the electrical connection interface 103. For example, for a gold finger type electrical connection interface 103, the electrical connector 201 is a slot connecter. Through such electrical connectors 201 that are connected to the respective electrical connection interfaces 103, the power and control signals of the secondary cell device 10 can all be transmitted to the expansion board 20.
The connection interface 203 serves as a communication channel for the expansion board 20. With reference to
Furthermore, the circuit 205 of the expansion board 20 may include a serial/parallel circuit, through which the power generated by the secondary cell devices 10 is integrated and then transmitted to the electronic device 30 through transmission of the connection interface 203. The circuit 205 of the expansion board 20 may be a power management circuit for managing the power wattage of the secondary cell devices 10. The circuit 205 of the expansion board 20 may also be a charging circuit for charging all secondary cell units of the secondary cell devices 10.
The electrical connection interface 103 of the secondary cell device 10 of this invention may also adopt a pluggable electrical connection interface to allow easy plug-in or removal assembly operation to the expansion board 20.
The secondary cell device 10 of this invention is able to achieve the following effects due to the provision of the electrical connection interface 103:
