Patent number: 11945094Abstract: An interface for a battery pack and an electrical combination. The interface may include a battery-receiving portion configured to receive a battery pack and including a cavity. The cavity is defined by a pair of sidewalls with rails defining a groove between the rails and a lower surface of the cavity. The rails are stepped or angled along a battery insertion axis and are configured to guide the sliding engagement of a battery pack within the battery-receiving portion.Type: GrantFiled: January 19, 2023Date of Patent: April 2, 2024Assignee: Milwaukee Electric Tool CorporationInventors: Kyle J. Radovich, Cameron R. Schulz, Mitchell Carlson, John G. Marx, Paul Rossetto, David M. Schwalbach

Publication number: 20230344073Abstract: A battery pack including a housing having a first portion and a second portion coupled to the first portion. The first portion has a first wall and an interface extends from the first wall. The interface includes a plurality of terminal apertures that provide access to electrical terminals within the housing. The second portion has a second wall, and the second wall is positioned opposite the first wall. A first plurality of vents extends through the first wall and a second plurality of vents extends through the second wall. A cumulative surface area of the first plurality of vents is different than a cumulative surface area of the second plurality of vents.Type: ApplicationFiled: June 30, 2023Publication date: October 26, 2023Inventors: Wyatt R. Silha, John G. Marx, Zachery Meyer, David M. Schwalbach, Joel D. Snyder, Francis X. Summins, Cameron R. Schulz
