A support member may be connectable in a removable and adjustable manner to a track assembly. The support member may include an electrical connector, a contact, and a biasing member. The electrical connector may be adjustable to a first position and a second position. The contact may be connected to the electrical connector and configured to engage a conductor of said track assembly. The contact may be engageable with said conductor when the electrical connector is in the first position. The contact may not be engageable with said conductor when the electrical connector is in the second position. The biasing member may be configured to bias the contact into engagement with said conductor when the electrical connector is in the first position.

A luminaire (30) or electrical unit for connection to a supporting rail (10) has a contacting element (40, 50, 60), which is introducible into the supporting rail profile (15) and has connection contacts (42, 52, 62) mounted adjustably in order to bear against lines (25) of the busbar (20) in a state in which the contacting element (40, 50, 60) has been inserted into the supporting rail profile (15). The contacting element (40, 50, 60) has at least one contact block (41, 42, 51, 52, 61, 62) with connection contacts (43, 53, 63), which is linearly laterally adjustable between an open position and a contacting position.

A method is disclosed for performing extension mobility via a headset connection. The method includes receiving a headset identifier from a headset. Also, the method includes, in response to receiving the headset identifier, sending the headset identifier to a device management server. Further, the method includes receiving a call control user identifier from the device management server, and sending, to a call control server, the call control user identifier. Still yet, the method includes receiving, from the call control server, a configuration profile associated with the call control user identifier. One or more settings of a desk phone are configured using the configuration profile.

An adapter, including a socket body, a guiding body, a movable conducting strip and a control member. The guiding body and the movable conducting strip are both disposed on one side of the socket body facing away from jacks, the control member is connected to the movable conducting strip in a transmission fashion, and is configured to drive the movable conducting strip to rotate relative to the socket body.

An electronic shelf label system includes a powered rail for holding electronic shelf labels. The front side of the rail includes a recess that is physically configured to receive a protrusion at the upper rear side of the shelf label. The shelf label further comprises a lower hook member for engaging with a lower edge of the rail. The rail may comprise two conductors for providing the labels with power and data for display on the label. Data and power may be provided via a controller and power module connected to the back of the rail.

A busbar connector includes an insulator body, a positive power delivery contact, a negative power delivery contact, and a side band contact. The insulator body has first prong and a second prong oriented in a longitudinal direction and proximate one another with a gap therebetween. The positive power delivery contact is on a first inner surface of the first prong adjacent the gap, and the negative power delivery contact is on a second inner surface of the second prong adjacent the gap. The side band contact is positioned on the insulator body and insulated from the positive power delivery contact and the negative power delivery contact by the insulator body.

A connector comprises a housing defining a terminal accommodating portion a supporting block. The connector further includes a pair of terminal assemblies mounted in the terminal accommodating portion and arranged to be spaced apart from each other. Each terminal assembly of the pair of terminal assemblies has a plate-shaped fixing portion extending in a first direction, and a terminal portion extending from the plate-shaped fixing portion in a second direction perpendicular to the first direction. Each terminal assembly further includes an elastic supporting arm extending from a lower end of the terminal portion adjacent to the plate-shaped fixing portion in a direction inclined to both the first direction and the second direction. The elastic supporting arms of the pair of terminal assemblies abutted against the supporting block.

A mounting assembly for mechanical and electrical engagement of a power module includes a stem having a base operably coupled to the power module and a distal end distal the base, a first electrode arm extending perpendicularly from a first side of the and having formed thereon a first electrode disposed on the first electrode arm to form a first incline surface, and a first locking arm extending perpendicularly from the first side of the and having formed thereon a first locking surface. A plane of the first incline surface intersects a plane of the first locking surface.

A lighting assembly connector is configured for being inserted into a lighting track. The lighting assembly connector includes a casing having a width defining a lateral direction and a length defining longitudinal direction. The length is greater than or equal to the width. The casing is definable as including three sections each defining one-third of the length. The three sections include a middle section, a first end section including a first longitudinal end of the casing and a second end section including a second longitudinal end of the casing. The middle section has a greater average width than each of the first end section and the second end section. The lighting assembly connector also includes a plurality of electrical contacts extending out of the casing each configured for contacting a respective line of the lighting track; and at least one fastener connected to the casing configured for removably connecting the lighting assembly connector to the lighting track.

An electrical power connector includes a connector housing having a receptacle receiving an elongated DC power distribution busbar, a first spring contact element arranged at a first side of the receptacle and pressed with a contact area to a first surface of the elongated DC power distribution busbar, and a second spring contact element pressed to a second surface of the elongated DC power distribution busbar opposite the first surface. The second spring contact element is arranged at a second side of the receptacle opposite to the first side. The power connector includes a temperature sensing device arranged inside the connector housing and monitoring a temperature at the first spring contact element and/or the second spring contact element.
