Battery pack isolation system
The present disclosure is directed to a cordless power tool vibration isolation system. A solution to negative impacts of vibration on a removable battery pack caused by operation of a cordless power tool. Isolating the battery pack from the power tool reduces wear and tear on the battery pack including the pack housing, the pack terminals and internal pack components. A battery pack interface of the power tool including a discrete interface housing that mates with the battery pack and a vibration isolation element that separates and isolates the combination of the discrete interface housing and the battery pack from the power tool and the power tool's associated motor induced vibrations.
1 . A power tool comprising:
a power tool housing having a battery pack receptacle,
a battery pack interface, and
a vibration isolation element positioned between the battery pack receptacle and the battery pack interface, wherein the vibration isolation element is wrapped around a portion of the battery pack interface.
2 . The power tool as recited in claim 1 , wherein the battery pack interface includes a housing and a set of terminals, the battery pack interface housing including a set of grooves and rails configured to cooperate with a correspondingly configured set of grooves and rails of a power tool interface of a removable battery pack.
3 . The power tool, as recited in claim 2 , wherein the set of terminals are placed in a mold and plastic material is injection molded into the mold to fix the set of terminals relative to each other and create the battery pack interface housing.
4 . A power tool comprising:
a power tool housing having a battery pack receptacle,
a battery pack interface, wherein the battery pack interface includes a housing and a set of terminals, the battery pack interface housing including a set of rails configured to cooperate with a correspondingly configured set of grooves of a power tool interface of a removable battery pack and wherein the battery pack interface rails and the power tool terminals are integrally formed in a single piece assembly, and
a vibration isolation element positioned between the battery pack receptacle and the battery pack interface.
5 . The power tool, as recited in claim 4 , wherein the single piece terminals/rails assembly is divorced from the power tool housing with 6 degrees of freedom.
