Description

Power supply and its output module

technical field

The utility model relates to a power supply and its output module, in particular to a power supply that improves power transmission efficiency by improving the output module.

Background technique

The power supply is used to provide a plurality of output powers, and a circuit board and an output module are arranged in the housing. The extension wire (commonly known as the flying lead) is used to extend the power of the circuit board to the power output board through the extension wire, and finally output multiple output power from the power output board. However, the extension wires are all calculated before ordering during the manufacturing process, so if the calculation is wrong or the wires are damaged, some wires will have to be reimbursed at that time, resulting in waste. In addition, in addition to the problem of waste heat in power transmission, the extension wire itself is also a kind of impedance, so it will inevitably reduce the power transmission efficiency of the power supply.

Among the currently disclosed technologies, existing patents attempt to solve the above problems. For example, the "Output Architecture of Power Supply" of Taiwan Invention Patent Publication No. 201033790 discloses the use of a plurality of conductive elements and a plurality of connection elements. , so that the power of the conversion circuit board can be transmitted to the power extension board via the conductive element and the connecting element. Since the extension wire is replaced by the conductive element and the connecting element, the power transmission distance is shortened, the problem of power transmission efficiency and waste heat is solved, and the cost problem derived from the use of the extension wire is also solved. However, the following disadvantages still need to be overcome:

1. Both the conductive element and the connection element are electrically connected to the power extension board or the conversion circuit board through their sides, and the elements only transmit power in a line contact manner, so the transmission efficiency is still low.

2. As mentioned above, the bonding strength between the power extension board and the conversion circuit board is relatively low because it is only in line contact.

3. Although the conductive element can be bent into an L shape so that the power extension board is placed vertically on the conversion circuit board, the positioning effect of the conductive element is not good before it is fixed. It is indeed inconvenient.

4. The power extension board still needs to connect multiple output wires to output power through the connection terminals. The entire power supply will be very cumbersome due to a long string of output wires when it is packaged or transported, and users also There may not be so many devices. Therefore, the unused output wires are not only wasteful, but also have the disadvantages of occupying space and hindering the flow of cooling air.
