A connector system includes a male connecter including a male housing defining a recess and a plurality of pins arranged within the recess; and a female connector including a female housing configured to be insertable into the recess of the male housing. The female housing includes: front and back portions; a pair of longitudinal sides that extend from the front portion to the back portion; a planar side that extends from the front portion to the back portion, the planar side connecting first ends of the pair of longitudinal sides; a rounded side that extends from the front portion to the back portion, the rounded side connecting second ends of the pair of longitudinal sides; a front surface defined at the front portion by the pair of longitudinal sides, the planar side, and the rounded side; and a plurality of sockets formed at the front surface.

A docking station for a medical device is described. In some examples, the docking station includes a frame and a base plate coupled to the frame. At least a portion of the base plate is coupled to a lower portion of the frame. In some examples, an electronic connector of the docking station is configured to couple to the medical device and to provide power to the medical device when the medical device is docked to the docking station. In some examples, a docking mechanism is coupled to an upper portion of the frame and configured to retain the medical device.

An embodiment of a cradle has a cradle body configured to support a printing device. The cradle has first and second printer capture flanges extending from the cradle body proximate a capture end of the cradle body. The cradle has first and second biased latches extending from the cradle body between the capture end and a release end of the cradle body. The cradle has a biased release member movable between a first position and a release position. The cradle has a release linkage supported by the cradle body, the release linkage coupling the biased release member and the first and second biased latches, wherein the release linkage is structured to drive the first and second biased latches from respective locked positions to respective unlocked positions in response to movement of the biased release member from a first position to a release position.

A connecting device including a housing, a connector and an elastic element is provided. The housing comprises a connector base including a bottom plate and a side wall, the bottom plate and the side wall jointly surround a space. The connector is disposed at the connector base and located in the space. The connector includes a positioning element and a plug terminal element connected to the positioning element. The positioning element including a limit portion is connected with the plug terminal element. The elastic element abuts between the plug terminal element and the bottom plate. When the plug terminal element is moved to a skewed position by an external force, the limit portion is moved away from the bottom plate. When the external force is disappeared, the limit portion returns to abut against the bottom plate, such that the plug element is in an upright position.

A kitchen appliance, including at least one kitchen appliance base and at least one preparation module is provided. The kitchen appliance base includes at least one electrical interface and at least one receiving region. The preparation module includes at least one electrical counter-interface for electrical contacting with the electrical interface. The electrical interface includes at least two power contacts and at least one auxiliary contact. The electrical counter-interface includes at least two power counter-contacts and at least one auxiliary counter-contact. In the kitchen appliance, the insertion forces for the electrical contacting for the user are reduced, are realized by the power contacts and the power counter-contacts, as well as the auxiliary contact and the auxiliary counter-contact being designed and configured such that the power contacts are electrically contacted with the power counter-contacts at a different point in time than is the auxiliary contact with the auxiliary counter-contact.

An electrical component socket includes a socket body arranged on a circuit board and including a receiving portion configured to receive an electrical component. The socket body includes an arrangement portion in which a row of contact pins to be in contact with leads of an IC package is arranged. At least one of these contact pins and another one of the contact pins adjacent to the at least one of the contact pins have an arrangement pitch that is narrower than a pitch between the terminals of the electrical component, and the other one of the contact pins and still another one of the contact pins adjacent to the other one of the contact pins have an arrangement pitch that is substantially equal to the pitch between the terminals of the electrical component.
