Embodiment Construction

[0012] Please refer to figure 2 , the printed circuit board 2 of the present invention includes a first current area 21, a second current area 22, connecting elements 26-29 and connecting ends 23-25. According to actual needs, the printed circuit board 2 may also include two or more connection elements.

[0013] The connection terminal 23 is arranged on one side 50 of the first current area 21 and is used for connecting with an external load (not shown in the figure), and the connection terminal 24 is arranged on the side 51 of the first current area 21 Near and close to the second current area 22 for connecting to an external load (not shown), the connection terminal 25 is arranged near the side 51 of the first current area 21 and away from the second current area 22, used to connect with an external load (not shown). The printed circuit board 2 inputs the driving current into the external load through the connection terminals 23-25, so the connection terminals 23-25 ​​can...

Abstract

The invention provides a printed circuit board (PCB). The PCB comprises a first current region, a second current region and a plurality of connection elements, wherein the first current region is electrically connected with the second current region by the connection elements; a plurality of connection terminals connected with external loads are arranged on the first current region; the connection elements are arranged between the first current region and the second current region; and the current path from each connection element to the corresponding connection terminal is the shortest. The PCB can avoid local overtemperature of the PCB caused by excessive current flowing through one connection element.

Description

technical field [0001] The present invention relates to a printed circuit board. Background technique [0002] Please refer to figure 1 , the printed circuit board 1 is provided with a first current area 11 and a second current area 12, the first current area 11 is provided with connection terminals 13-15 for connecting with an external load, and the current in the second current area 12 is connected by Elements 16 - 19 flow into first current region 11 and further flow through current path 141 to connection 14 , through current path 151 to connection 15 and through current path 131 to connection 13 . The first current region 11 and the second current region 12 have different operating currents, but their operating voltages may be the same, for example, both are 12V. In view of the high driving current of the external load, it is generally necessary to connect the first current region 11 and the second current region 12 through the connecting elements 16-19. However, the ...
