Battery charger with body slot and catch arrangement to prevent incorrect battery orientation
First Claim
1. A battery charging apparatus for use in charging a rechargeable battery having battery terminals and a battery slot and catch arrangement, said battery charging apparatus comprising:
- a charger body having a battery connecting part;
wherein said connecting part of said charger body is provided with charger terminals for electrical connection with the battery terminals of the battery;
wherein said connecting part of said charger body is provided with a body slot and catch arrangement which, when the battery is mounted to said connecting part of said charger body in a correct orientation, matches with the battery slot and catch arrangement of the battery and allows the battery terminals of the battery to electrically connect with said charger terminals of said connecting part and, when the battery is mounted to said connecting part of said charger body in an incorrect orientation, does not match with the battery slot and catch arrangement of the battery and prevents the battery terminals of the battery from electrically connecting with said charger terminals of said connecting part;
wherein said connecting part comprises a connecting recess in said charger body;
wherein said body slot and catch arrangement comprises a body slot and a body catch; and
wherein said body slot comprises an upwardly opening groove formed about an inner peripheral portion of said connecting recess.

Abstract
A battery charger is provided with a connecting part for connection of a rechargeable battery in a freely removable fashion. The charger body has charger terminals protruding from the connecting part to electrically connect with battery terminals of the rechargeable battery. The connecting part of the charger body has a body slot and catch to allow connection thereto of only a particular rechargeable battery. The slot and catch of the body are designed to match with a battery slot and catch of the rechargeable battery when the appropriate rechargeable battery is normally connected to the connecting part, but to not match with the battery slot and catch when the connecting part of the rechargeable battery is abnormally connected. Both catches of the battery slot and catch and of the body slot and catch are provided to protrude at a location facing each other to prevent the electrical connection of the terminals when the battery slot and catch and the body slot and catch do not match each other.
