Abstract
A battery protection device (10) has a hollow casing body (11) formed by ultrasonic welding of a first casing member (12) and a second casing member (13) with respect to casing body (11), a first external terminal extends from a first end surface (11b) and a second external terminal extends from a second end surface (11c). The battery protection device (10) further has a first contact (18) connected to the first external terminal, a second contact (16) connected to the second external terminal, and a bimetallic member (17) which enables the connection between and first and second contacts to be opened and closed. In a second embodiment one of the casing member (72) is formed of a sheet of electrically insulative material which is received over and closes the opening in the other casing member (71).
