Description
Technical field:
The utility model relates to the supply unit technical field, refers in particular to a kind of power supply change-over device.
Background technology:
Along with the development of society, increasing family expenses small electric apparatus has entered each family, and as mobile phone, notebook computer etc., and these family expenses small electric apparatus major parts all need to use power supply change-over device, convert civil power to low dc voltage.Existing power supply change-over device mainly is to be made of shell, circuit board and plug, and the volume of its circuit board is all bigger, makes the shell of mounting circuit boards also will correspondingly increase volume, and promptly the volume of whole power supply change-over device is big, weight is big, uses inconvenient.Also having its whole functional circuit all is that design is on a circuit board, if some functional circuits have been broken, need the more time to search, be inconvenient to keep in repair, if remove certain functional circuit simultaneously because production needs, then must redesign a circuit board and meet the needs of production, waste human and material resources, increase production cost.
The utility model content:
The purpose of this utility model is exactly to provide a kind of volume power supply change-over device little, simple in structure and easy to use at the deficiency of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is: it comprises outer casing upper cover, shell lower cover and plug, outer casing upper cover and shell lower cover snapping, plug is the bottom that is fixed on the shell lower cover, be provided with main circuit board and auxiliary circuit board between outer casing upper cover and the shell lower cover, auxiliary circuit board is connected with main circuit board, and auxiliary circuit board is provided with independently functional circuit.
Described auxiliary circuit board is provided with pin, and main circuit board is provided with the jack with pin size coupling, and jack is pegged graft with pin and cooperated.
Described auxiliary circuit board is welded on the main circuit board.
Be welded with LED on the described main circuit board, auxiliary circuit board is provided with the functional circuit that is used to control LED.
The utility model beneficial effect is: adopted between outer casing upper cover and the shell lower cover and be provided with main circuit board and auxiliary circuit board, auxiliary circuit board is connected with main circuit board, auxiliary circuit board is provided with independently functional circuit, reduced the volume of main circuit board, auxiliary circuit board is grafting or is welded on the main circuit board, can disassemble, satisfy different production needs, convenient production and maintenance, the utility model is simple in structure, easy to use, can reduce production costs effectively and saves human and material resources.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a decomposing schematic representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see accompanying drawing 1, shown in 2, the utility model comprises outer casing upper cover 1, shell lower cover 2 and plug 3, outer casing upper cover 1 and shell lower cover 2 snappings, plug 3 is the bottoms that are fixed on shell lower cover 2, be provided with main circuit board 4 and auxiliary circuit board 5 between outer casing upper cover 1 and the shell lower cover 2, auxiliary circuit board 5 is provided with pin 6, main circuit board 4 is provided with the jack 7 with pin 6 size couplings, the pin 6 of auxiliary circuit board 5 is plugged in the jack 7 of main circuit board 4, just auxiliary circuit board 5 is fixed on the main circuit board 4, simultaneously can also on main circuit board 4, pad be set, auxiliary circuit board 5 is welded on the main circuit board 4; Be welded with on the described main circuit board 4 and be used to indicate battery charger to make the LED8 of state, auxiliary circuit board 5 is provided with the functional circuit that is used to control LED8.
The utility model is simple in structure, main circuit board 4 and auxiliary circuit board 5 are separately produced, processing, auxiliary circuit board 5 can directly be welded on the main circuit board 4, perhaps can assemble with the mode of pegging graft, be fixed with socket or the jack 7 corresponding on the main circuit board 4 with the pin 6 of auxiliary circuit board 5, auxiliary circuit board 5 is plugged into socket or jack 7 gets final product, to realize being electrically connected of auxiliary circuit board 5 and main circuit board 4, then main circuit board 4 is fixed on the shell lower cover 2, outer casing upper cover 1 and shell lower cover are connected together for 2 mouthfuls, promptly finished assembling process of the present utility model, simple in structure, reduce volume; In addition, if remove the deixis of LED8 because customer requirement or production need, then as long as auxiliary circuit board 5 is not installed, just can realize, needn't redesign a circuit board, convenient production and maintenance reduced production cost effectively, simultaneously, the utility model can also be applied to other supply unit.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
