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. Apparatus comprising:
a battery including:
opposing front and rear sides provided in a loading direction;opposing right and left sides provided between the front and rear sides;opposing first and second sides provided between the front and rear sides, right and left sides;a terminal portion located at one of said sides, the terminal portion including a plurality of ribs separated by respective slits opened in orthogonal directions, one of which is in a direction facing toward the front side, and having terminals disposed in the slits; andan erroneous loading prevention groove provided at a corner of the right side and the second side and extending in the loading direction, the groove having a step surface parallel to the second side, and an imaging apparatus that receives the battery, the imaging apparatus including:
a battery receiving portion to receive the battery loaded in the imaging apparatus; andelectric terminals configured to establish an electric connection with the terminals of the battery when the battery is loaded in the imaging apparatus.
