Abstract
An electric device includes a housing, an electromechanical assembly housed within the housing, a battery arranged within the housing and comprising at least one tabless battery cell, and at least one connector that is electrically coupled to the electromechanical assembly and the battery so as to electrically connect the electromechanical assembly and the battery. The at least one connector is mechanically decoupled from at least one of the electromechanical assembly and the battery.
Claims20
An electric device comprising:
- a housing;
- an electromechanical assembly housed within the housing;
- a battery arranged within the housing and comprising at least one tabless battery cell;
- and
- at least one connector that is electrically coupled to the electromechanical assembly and the battery so as to electrically connect the electromechanical assembly and the battery,
- wherein the at least one connector is mechanically decoupled from at least one of the electromechanical assembly and the battery.
A power tool comprising:
- a housing;
- an output shaft configured to receive a working tool;
- an electromechanical assembly housed within the housing, the electromechanical assembly including a motor configured to rotate the output shaft;
- a battery arranged integrally within the housing and comprising at least one tabless battery cell;
- and
- at least one connector that is electrically coupled to the electromechanical assembly and the battery so as to electrically connect the electromechanical assembly and the battery,
- wherein the at least one connector is mechanically decoupled from at least one of the electromechanical assembly and the battery.
A rotary tool comprising:
- an elongated housing having a longitudinal axis defined by a main extent direction of the elongated housing;
- an output shaft configured to receive a working tool;
- an electromechanical assembly housed within the housing, the electromechanical assembly including a motor configured to directly drive the output shaft in rotation, and a circuit board configured to control operation of the motor;
- a battery arranged integrally within the housing and comprising at least one tabless battery cell;
- and
- at least one connector that is permanently electrically coupled to the electromechanical assembly and to the battery so as to electrically connect the electromechanical assembly and the battery,
- wherein the at least one connector is mechanically decoupled from at least one of the electromechanical assembly and the battery, and
- wherein the at least one connector is electrically coupled to and mechanically decoupled from the at least one of the electromechanical assembly and the battery via at least one first flexible wire.
