Method for preventing erroneous loading of component-to-be-loaded on main body side apparatus, component-to-be-loaded and battery pack

摘要

In case a similar component-to-be-loaded is erroneously loaded on a main body side apparatus, contact of terminals are avoided. To this end, a video camera (main body side apparatus) 1 has a main body side terminal 30, and a battery pack (component-to-be-loaded) 100 has a battery side terminal (component-to-be-loaded side terminal) 120. In the vicinity of the battery side terminal of the component-to-be-loaded, a discriminating tab 111 is provided, and a blocking portion 19 is provided in the vicinity of the main body side terminal of the video camera (main body side apparatus) for determining whether or not its loading is permitted based on the combination of concave and convex engagement with respect to the above-mentioned discriminating tab, and when the loading is not permitted due to the interference between the blocking portion and the above-mentioned discriminating tab, an electric connection between the main body side terminal and the battery side terminal (component-to-be-loaded side terminal) is not to be established.

主权项

1. A battery having battery cell, the battery comprising:
a first end surface; a first surface provided approximately perpendicular to the first end surface; a first side surface provided approximately perpendicular to both the first end surface and the first surface; a terminal block located at and projecting from the first end surface and including terminal grooves opened to both the first surface and the first end surface; electrode terminals provided inside and accessible through the terminal grooves; a groove portion opened to both the first end surface and one of the surfaces which are approximately perpendicular to the first end surface; wherein the first end surface includes a pair of positioning ribs projecting from the first end surface, and offset from a center line of the first end surface, and wherein the terminal block is disposed between the positioning ribs at the first end surface in a step portion of the first end surface.
