The housing defines a sliding slot and at least two guide holes. The at least two contacts are received in the housing and are operable to protrude out of the housing via the at least two guide holes. The transmission mechanism is received in the housing and is used for driving the at least two contacts to protrude out of the housing. The driving member is received in the housing and partially extends out of the housing after passing through the sliding slot. The driving member is coupled to the transmission mechanism, and is capable of sliding in the sliding slot to activate the transmission mechanism to drive the at least two contacts to protrude out of the housing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Battery charger with retractable contacts","description":"A battery charger includes a housing, at least two contacts, a transmission mechanism and a driving member.
