Abstract

PURPOSE:To prevent erroneous indication of polarity due to mistake in work by providing marks for indicating polarity of +, and - conforming to the position of a pair of terminals near mounting of the terminal of a frame by embossing or punching. CONSTITUTION:Polarity indication is made by providing polarity indication marks P3, N3 of +, and - by press work such as embossing or punching etc. near the mounting part of the terminal of a frame 1. In this case, + mark is positioned near a positive terminal 5b, and - mark is positioned near a negative terminal 5c. By this way, forming of the frame 1 and indication of polarity can be made simultaneously, and work for indicating polarity on the frame 1 (polarity indication on the terminal 5, polarity indication on the bottom plate 4 by marking) becomes unnecessary, and erroneous indication of polarity caused by mistake in work can be prevented. Further, as polarity indication marks P3, N3 are provided near the terminal 5, erroneous connection can also be prevented.
