A printer includes a board including a connector to which a cable is connected, and a housing covering the board and having an opening through which the connector is accessible, wherein a cable gripping portion that is gripped when the cable is connected is located outside the opening in a state where the cable is connected to the connector, and in which the housing includes a connector cover movable to a cover position at which the connector cover covers an upper side and a lateral side of the cable gripping portion, and an open position at which the connector cover opens at least on a vertical upper side of the cable gripping portion.

Explosion-proof pressure-resistant housing with a receiving part for electric operating components and with a closure part that closes the receiving part via a bayonet catch, wherein the closure part has a cylindrical segment that forms a flameproof joint when inserted into the receiving part, the cylindrical segment of the closure part has pins and the cylindrical outer wall of the receiving part contains longitudinal slots, at the ends of which longitudinal slots short transverse slots connect for receiving the pins, where a locking part is slid onto the closure part and includes locking elements distributed across the periphery and engaging in the longitudinal slots such that the pins are prevented from rotating out of the transverse slots, and where the locking part is fastened to the closure part via at least one fastener that detachable exclusively via a tool.

An actuator assembly for actuating an electrical switch housed in sealed electrical enclosure is disclosed. The actuator assembly includes a handle assembly including a handle positioned on an exterior of a cover of the sealed enclosure, a trip bracket positioned within the sealed enclosure and a shaft connecting the handle to the trip bracket. A slider actuator is slidably mounted over an electrical switch positioned within the enclosure and operatively associated with or coupled to a toggle of the electrical switch. The slider actuator has a drive link which is adapted to engage the trip bracket such that rotation of the handle activates the drive link which causes linear movement of the slider actuator to move the electrical switch between on and off positions. The use of the slider actuator allows a higher density of electrical switches to be stacked within the sealed enclosure.

The disclosure relates to a battery pack, comprising a casing; a built-in circuit disposed inside the casing; a consumable component disposed inside the casing and connected in series to the built-in circuit, wherein an opening corresponding to the consumable component is provided on the casing; a safety switch disposed inside the casing, wherein an on/off of the safety switch controls a connection/disconnection of the built-in circuit; and a cover body disposed corresponding to the opening, wherein the cover body has a first state in which the cover body is capped at the opening, so that the safety switch is switched on and the built-in circuit is connected, and a second state in which the cover body is detached from the opening, so that the safety switch is switched off and the built-in circuit is disconnected.

A device assembly for accommodating an electrically operated device may include a housing made from a plastic, delimiting a housing interior space, and having a viewing window formed therein that may be closed by a window pane made of a transparent material. The device may include an electrically operated device arranged inside the housing interior space, on the outside of which at least one actuatable control element may be provided. An aperture may be formed in a housing wall in which an actuating element made from an elastic plastic may be arranged at least partially and may be operable by a user of the electrically operated device. The actuating element may be coupled mechanically to the control element such that the control element is operable from outside the housing. An inner housing part made from an elastic plastic may be arranged on an inner side of the housing wall.

An actuator assembly for actuating electrical switches housed in an electrical enclosure is disclosed. The assembly includes at least one handle assembly including a handle positioned above a cover of the enclosure, a trip bracket positioned below the cover and a shaft connecting the handle to the trip bracket. At least one slider actuator is slidably mounted over the electrical switch and coupled to a toggle of the electrical switch. The slider actuator has a drive link which is adapted to be engaged with the trip bracket such that rotation of the handle causes the drive link to slide which in turn causes a linear movement of the slider actuator to toggle the electrical switch. The use of the slider actuator allows a higher density of electrical switches to be stacked inside the enclosure.
