Description

Terminal, connector for substrate, and method for manufacturing terminal Technical Field The present disclosure relates to a terminal, a connector for a substrate, and a method of manufacturing a terminal. Background Patent document 1 discloses a connector for a substrate. The terminals of the substrate connector are formed by punching a single metal plate and then bending the metal plate. The terminal has a sheet-like fitting portion, a tab portion and a bridge portion that are provided integrally with an end portion on the opposite side of the fitting portion, and a sheet-like welding portion that is provided integrally with the bridge portion. Such a connector for a substrate is also disclosed in patent document 2. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 2000-68014 Patent document 2 Japanese patent application laid-open No. 2000-77120 Disclosure of Invention Problems to be solved by the invention However, plating is performed in advance at the connection portion such as the tab portion or the welded portion in order to improve connection reliability. In this case, when workability and cost of the plating step are considered, it is preferable to perform plating (plating-before-plating treatment) before punching the metal plate. However, according to the plating treatment, the plate surface of the metal plate becomes a plated surface, but the cut surface (plate thickness surface) of the metal plate after punching is not a plated surface. If the cut surface of the connection portion becomes the main surface for connection with the counterpart conductor, connection reliability may not be ensured. Accordingly, the present disclosure is directed to a technique capable of improving connectivity of terminals. Further, the object is to provide a method for manufacturing such a terminal. Means for solving the problems The terminal of the present disclosure includes a terminal body having a quadrangular cross section extending from one end to the other end, a terminal contact portion provided on one end side of the terminal body and contacting a counterpart terminal, and a substrate contact portion provided on the other end side of the terminal body and contacting a substrate, wherein 2 surfaces facing opposite sides of 4 surfaces around the terminal body are formed with plated surfaces having plating layers, and the plated surfaces of the terminal contact portion and the plated surfaces of the substrate contact portion face directions different from each other. The connector for a substrate of the present disclosure includes the terminal, wherein the plated surface of the terminal contact portion is disposed on a side contacting the contact portion of the counterpart terminal, and the plated surface of the substrate contact portion is disposed to stand up from the surface of the substrate. The method for manufacturing a terminal of the present disclosure includes a step of plating two plate surfaces of a plate-like metal material, and setting the two plate surfaces as the plated surfaces, a step of cutting the metal material having the plated surfaces to obtain a terminal body base material along the two plate surfaces, and a step of performing a process of making the plated surfaces different in orientation between a portion of the terminal body base material which can become the terminal contact portion and a portion which can become the substrate contact portion.
