Problems solved by technology

[0004] However, when the electrical specifications require to provide a voltage and current of 3.8 volts and 50 amperes, the power supply device 10 is not suitable for use
On the other hand, if the user is not careful, the power module M2 that can provide a voltage of 5 volts and a current of 20 amperes is inserted into any slot of the slot area R1, or the power module M2 that can provide a voltage of 12 volts and a current of 8 amperes is inserted into any slot of the slot area R1. When the power module M3 is inserted into any slot of the slot area R1 or R2, it will damage the external circuit coupled to the above-mentioned output terminal V1 or V2

Embodiment Construction

[0013] Such as Figure 2a and Figure 2b Shown in is a combined power supply system of the present invention, including a printed circuit board PCB, several protrusions S1-Sn, several connecting parts T1 and several power modules CM1. The printed circuit board PCB has several power conducting lines L1-Ln for transmitting several predetermined voltages of different potentials, and one of the power conducting lines L1-Ln is coupled to a main power Vi.

[0014] These protrusions S1, S2-Sn are arranged on the printed circuit board PCB, these protrusions S1-Sn each have several insulating blocks C1-Cn, wherein each of these insulating blocks is provided with a terminal, and each of these insulating blocks C1-Cn The inner terminals are respectively electrically connected to one of the wires L1-Ln.

[0015] Several connection portions T1-Tn each have a plurality of slots P1-Pn corresponding to these insulating blocks C1-Cn of these protrusions S1-Sn, and a terminal (not shown in I...

Abstract

This invention relates to a combined power supply system including a PCB with several power conductive lines for transmitting several definite voltages of different potentials and one couples to a main power, several projected seats set on the PCB having several insulation blocks with a terminal in each connecting electrically to one of the conduction lines, several connecting parts with several plug, slots corresponding to the projected blocks with one terminal in each slot electrically connecting terminals in the insulation blocks and several power modules connecting to these connection parts for converting the main power to one of the definite voltages and become an output power supply outputting to a related conductive line.

Description

technical field [0001] The present invention relates to a power supply system, in particular to a power supply system whose electrical specifications can be replaced arbitrarily, and can prevent external circuit damage caused by wrong insertion position or specifications not conforming to use when plugging and unplugging a power supply module to change specifications . Background technique [0002] Currently on the market, the electrical specifications of power supplies often change with new products. However, it is quite time-consuming to re-develop a power supply with new electrical specifications and to apply for relevant certifications. Figure 1a Shown in is a known plug-in power supply device 10, which has three slot areas R1, R2 and R3, which are respectively used to provide power supplies of three different voltages, such as 3 volts, 5 volts, and 12 volts. , to the output terminals V1, V2 and V3. The slot areas R1 , R2 and R3 each have three slots and have an input ...
