A multifunction carrier for receiving circuit components of a battery system for an electric vehicle is disclosed, wherein the multifunction carrier includes: a busbar assembly with at least one charging connection rail and a drive connection rail; and an insulating housing in which the busbar assembly is embedded, wherein the insulating housing has openings exposing contact surfaces of the connecting rails, and wherein the insulating housing has plug connectors which are designed to provide a pluggable mechanical and electrical contact between the circuit components of the battery system with the open contact surfaces of the connecting rails. The invention further relates to a high-voltage contactor for a battery system of an electric vehicle.

A wire connection terminal structure includes a case main body. Wire plug-in ports are connected with an electro-conductive module. Arcuate slide guide slots are disposed on the electro-conductive module. Rotary buttons are pivotally disposed in the case main body. Each rotary button has a movable section. A pin is disposed on the movable section. The pin is extended into the slide guide slot. At least one abutment leaf spring is pivotally disposed between the rotary button and the electro-conductive module. When a conductive wire passes through the wire plug-in port into the lateral side of the electro-conductive module, the rotary button can be driven to make the movable section gradually displace from a section of the abutment leaf spring near the pivotally rotational center to an outer lateral side. The abutment leaf spring is pushed to engage with the conductive wire.

A junction box including a box body and a conductive bar. A guide plate extends from a lead insertion opening, with a laterally extended connection portion at its extended end to connect the box body. First and second support plates and edges of the guiding plate form passages accessible to a lead insert space defined by the guiding plate, the connecting portion, the second support plate and the box body. The conductive bar has a bent conductive arm that moves into the inside of the lead insert space by an elastic force, therefore locked in said space, after it passes the passages.

An electronic device is provided including a connector comprising a plurality of terminals, the connector being configured to be connected with an external device; a circuit electrically connected to at least a subset of the plurality of terminals; and a processor electrically connected to the circuit, wherein the processor is configured to detect a connection of the external device through the connector, detect a first impedance of a first electrical path including a first terminal of the plurality of terminals, detect a second impedance of a second electrical path including a second terminal of the plurality of terminals, and determine a connection direction of the external device connected through the connector, based on the first impedance and the second impedance.

A distribution block for attaching to a support rail extending in a support direction comprises an insulating housing, and a conductive member arranged in the insulating housing. A mounting assembly of the distribution block is connected to the insulating housing for attaching to the support rail. The distribution block is mountable on the support rail in a longitudinal configuration wherein the extension direction of the insulating housing is substantially parallel to the support direction, and in a transverse configuration wherein the extension direction of the insulating housing is transverse to the support direction.

A bus device of a terminal block includes a case and a latch assembly. The case has a connecting side and is formed with a sliding trough. The latch assembly includes an actuator and a locking peg. The actuator is disposed in the sliding trough and movable along the sliding trough between a release position and a locking position. The actuator has an actuating ramp set. The locking peg is axial-rotatably disposed in the case and arranged corresponding to an end of the sliding trough. An end of the locking peg projects from the connecting side and has an inverted hook. The locking peg has a protrusive key abutting against the actuating ramp set. When the actuator moves between the release position and the locking position, the actuating ramp set is configured to push the protrusive key to axially rotate the locking peg.

An electrical distribution block includes a first base, a second base, and a spacer plate discrete from the first and second base. The spacer plate is positioned between first base and the second base and secures the first base to the second base. A conductor block is connected to at least one of the first base or the second base. The conductor block includes a primary tap and a secondary tap.

A data acquisition module including a connection panel subassembly having a housing, a computing device subassembly, electrically coupled to the connection panel and having a housing configured to mechanically couple to the housing of the connection panel assembly; and a user interface subassembly, electrically coupled to the computing device subassembly and having a housing configured to mechanically couple to the housing of the computing device assembly.

A marker strip has a strip-shaped labelling strip formed of a first plastic material, which can be labelled on a first labelling side using a printer. A second side of the strip opposite the first side has a plurality of marker latching profiles formed of a second plastic material. The profiles are configured for latching in marker latching receptacles of serially arranged electrical devices. The marker strip has a main direction of extent and the latching profiles are arranged in the main direction of extent in a grid dimension on the second side of the labelling strip. The grid dimension in which the latching profiles are distributed on the second side of the labelling strip is smaller than or equal to 2 mm.

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.
