In the figure, 1 is a metal female terminal; 2 is a metal male terminal; 3 is a circuit board; 4 is a bonding pad; 5 is a connector; 101 is a threaded hole, 201 is a stud, and 202 is a nut.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, the wiring system for separated electrical connection of a circuit board and a connector of the present utility model comprises a connector 5, and further comprises a plurality of groups of metal female terminals (1) and metal male terminals 2 which are adapted to each other, wherein the metal female terminals 1 and the metal male terminals 2 are detachably and fixedly connected to the circuit board 3 through holes of a bonding pad 4 on the circuit board 3.
As shown in fig. 2 and fig. 3, one end of the metal female terminal 1 is provided with a threaded hole 101, one end of the metal male terminal 2 is provided with a stud 201 corresponding to the threaded hole 101, that is, the diameter of the threaded hole 101 is matched with the diameter of the through hole of the bonding pad 4 of the circuit board 3 and the diameter of the stud 201 of the metal male terminal 2, and the diameters of the threaded hole 101 and the stud 201 are smaller than the diameter of the through hole of the bonding pad 4.
