A connector includes a plurality of contacts each including first and second contact pieces provided with first and second contact portions at distal end sides, respectively, that come into contact with conductor portions of two insertable/removable connection objects when the connection objects are inserted, and a connection portion to be connected and secured to a board. The connector further includes a housing that holds the contacts in an array and includes an insertion opening of a shape that allows insertion of the connection objects and a battery from a same direction, and a terminal is arranged in the housing and spaced apart from the contacts in a width direction of the housing, the terminal including third and fourth contact pieces provided with third and fourth contact portions on distal end sides, respectively, configured to come into contact with the conductor portion of one of the connection objects and the battery.

Flexible electronic devices may be provided. A flexible electronic device may include a flexible display, a flexible housing and one or more flexible internal components configured to allow the flexible electronic device to be deformed. Flexible displays may include flexible display layers, flexible touch-sensitive layers, and flexible display cover layers. The flexible housing may be a multi-stable flexible housing having one or more stable positions. The flexible housing may include a configurable support structure that, when engaged, provides a rigid support structure for the flexible housing. The flexible internal components may include flexible batteries, flexible printed circuits or other flexible components. A flexible battery may include flexible and rigid portions or may include a lubricious separator layer that provides flexibility for the flexible battery. A flexible printed circuit may include flexible and rigid portions or openings that allow some rigid portions to flex with respect to other rigid portions.

A battery retention system is configured to facilitate insertion and removal of batteries from an electronic device. The electronic device includes a housing that defines a battery cavity for receiving a battery. The battery cavity has a floor. A floor contact extends from the floor. The floor contact is configured to provide a biasing force to push the battery away from the floor of the battery cavity. The housing has tabs extending into the battery cavity to hold the battery in the battery cavity against the biasing force of the floor contact. The battery cavity has a recess that allows the battery to move in a lateral direction along the floor to a position where the battery disengages from at least one of the tabs to allow at least a portion of the battery to be pushed out of the battery cavity by the biasing force of the floor contact.

An electronic key includes a housing including a battery housing portion that houses a battery, the battery housing portion being provided in the housing, a battery terminal, arranged within the battery housing portion, that makes contact with one electrode of the battery housed within the battery housing portion, and a board, arranged within the battery housing portion, including a first conductive portion that makes contact with the battery terminal and is electrically connected to the one electrode of the battery via the battery terminal, and a second conductive portion that makes contact with and is electrically connected to another electrode of the battery.
