Abstract

The present disclosure is directed to an electric power tool system with cordless power tools and removable, rechargeable battery packs that mate with the power tools to provide stored energy to the power tools. The battery packs may include a first battery pack having a basic interface and a second battery pack having an advanced interface. The power tools may include a first power tool having a basic interface and a second power tool having an advanced interface. The basic interface battery pack may mate with both the basic interface power tool and the advanced interface power tool. The advanced interface battery pack may mate with both the basic interface power tool and the advanced interface power tool.

Dependent claims

A removable battery pack for providing electrical energy to a cordless electric tool, the removable battery pack comprising:

a housing having a forward side and a rearward side, the forward side including a plurality of terminal slots;
and an interface including a first set of rails and a second set of rails, the second set of rails having a set of front walls, the first set of rails positioned closer to the forward side than the second set of rails, and the first set of rails starting forward of the set of front walls of the second set of rails such that the first set of rails do not overlap with the second set of rails, wherein
the first set of rails includes two rails in a first plane and the second set of rails includes two rails in a second plane, each of the two rails of the first set of rails includes aside wall, the side walls of the two rails of the first set of rails being parallel to each other and separated by a first distance and each of the two rails of the second set of rails includes a side wall, the side walls of the two rails of the second set of rails being parallel to each other and separated by a second distance, the first distance being less than the second distance.

A cordless electric power tool for receiving electrical energy from a removable battery pack, the cordless electric power tool comprising:

a housing having a forward side and a rearward side, the forward side including a plurality of terminal slots;
and an interface including a first set of power tool rails and a second set of power tool rails, the second set of power tool rails having a set of front walls, the first set of power tool rails positioned closer to the forward side than the second set of power tool rails, and the first set of power tool rails starting forward of the set of front walls of the second set of power tool rails such that the first set of power tool rails do not overlap with the second set of power tool rails, wherein
the first set of power tool rails includes two rails in a first plane and the second set of power tool rails includes two rails in a second plane, each of the two rails of the first set of power tool rails includes a side wall, the side walls of the two rails of the first set of power tool rails being parallel to each other and separated by a first distance and each of the two rails of the second set of power tool rails includes a side wall, the side walls of the two rails of the second set of power tool rails being parallel to each other and separated by a second distance, the first distance being less than the second distance.

A cordless power tool system, comprising:

a removable battery pack configured to mate with a cordless power tool and to provide electrical energy to the cordless power tool, the removable battery pack comprising:
a battery pack housing having a forward side and a rearward side, the forward side including a plurality of terminal slots that provide access to a plurality of battery terminals;
and
an interface including a first set of battery pack rails and a first set of battery pack grooves associated with the first set of battery pack rails and a second set of battery pack rails and a second set of battery pack grooves associated with the second set of battery pack rails, the second set of battery pack rails having a set of front walls, the first set of battery pack rails and the first set of battery pack grooves positioned closer to the forward side than the second set of battery pack rails and the second set of battery pack grooves, and the first set of battery pack rails starting forward of the set of front walls of the second set of battery pack rails such that the first set of battery pack rails do not overlap with the second set of battery pack rails, wherein
the first set of battery pack rails includes two rails in a first plane and the second set of battery pack rails includes two rails in a second plane, each of the two rails of the first set of battery packs rails includes a side wall, the side walls of the two rails of the first set of battery pack rails being parallel to each other and separated by a first distance and each of the two rails of the second set of battery pack rails includes aside wall, the side walls of the two rails of the second set of battery pack rails being parallel to each other and separated by a second distance, the first distance being less than the second distance;
and
a cordless power tool configured to mate with the removable battery pack and to receive electrical energy from the removable battery pack, the cordless power tool comprising:
a power tool housing having a forward side and a rearward side, the rearward side including a plurality of tool terminals configured to mate with the plurality of battery terminals upon mating with the removable battery pack;
and
an interface including a first set of power tool rails and a first set of power tool grooves associated with the first set of power tool rails and a second set of power tool rails and a second set of power tool grooves associated with the second set of power tool rails, the second set of power tool rails having a set of front walls, the first set of power tool rails and the first set of power tool grooves positioned closer to the rearward side than the second set of power tool rails and the second set of power tool grooves, and the first set of power tool rails starting forward of the set of front walls of the second set of power tool rails such that the first set of power tool rails do not overlap with the second set of power tool rail, wherein
the first set of power tool rails includes two rails in a first plane and the second set of power tool rails includes two rails in a second plane, each of the two rails of the first set of power tool rails includes a side wall, the side walls of the two rails of the first set of power tool rails being parallel to each other and separated by a first distance and each of the two rails of the second set of power tool rails includes a side wall, the side walls of the two rails of the second set of power tool rails being parallel to each other and separated by a second distance, the first distance being less than the second distance;
and
the first set of battery pack rails and the first set of battery pack grooves and the second set of battery pack rails and the second set of battery pack grooves and the first set of power tool rails and the first set of power tool grooves and the second set of power tool rails and the second set of power tool grooves shaped, dimensioned and configured such that when the battery pack is mated with the power tool the first set of battery pack rails is received in the first set of power tool grooves and the second set of battery pack rails is received in the second set of power tool grooves and the first set of power tool rails is received in the first set of battery pack grooves and the second set of power tool rails is received in the second set of battery pack grooves.
