The invention relates to a coupling for power cables, consisting of a plug part and a socket part, said plug part having a basic body comprising a coupling pin on which a locking pin is arranged. The locking pin is movably mounted on the coupling pin so as to be displaceable in the axial direction of the coupling pin. The locking pin is biased to a basic position towards a back end of the coupling pin by a spring force. When the coupling is being locked, the locking pin engages a helical groove of the socket part and, thus, moves towards the front end of the coupling pin. This movement causes the spring device to load.

An electrical connector is configured to couple an electrical conductor to a support surface of an electrical device. The electrical connector includes a terminal block having a connecting aperture and a threaded aperture. The connecting aperture is configured to receive the electrical conductor. The electrical connector includes a locking fastener having threads to be receivable within the threaded aperture. The locking fastener is configured to move in a first rotational direction to secure the electrical conductor against movement relative to the terminal block. The locking fastener is configured to move in a second rotational direction to release the electrical conductor from the terminal block. The electrical connector includes a lock engaging the locking fastener in a locked position to inhibit movement of the locking fastener in the second direction. The lock disengages the locking fastener in an unlocked position to permit movement of the locking fastener in the second direction.

A high-current module connector includes at least one electrical connector with a first connector portion, a threaded socket and a housing, wherein the housing is designed in the manner of a hollow body and encloses a housing interior, wherein the housing has a latching device, a first insertion opening arranged at the end and a feed opening on a housing portion extending circumferentially around the installation axis, wherein the connector traverses the first feed opening in such a way that the first connector portion and the threaded socket arranged on the first connector portion are arranged in the housing interior, wherein the latching device is arranged at the feed opening, wherein the latching device retains the first connector portion and the threaded socket in the housing interior by the threaded socket bearing against the latching device. A module connector system including the high-current module connector and a method for installing the high-current module connector are provided.

A connection arrangement (4) for connecting a first electrical conductor (2) to a second electrical conductor (3) comprises a first fastening element (6) that is inserted into an aperture (9a) defined in the first electrical conductor (2) and which is supported on a side of the first electrical conductor (2) facing away from the second electrical conductor (3), and a second fastening element (7) which is supported on a side of the second electrical conductor (3) facing away from the first electrical conductor (2). The first fastening element (6) and the second fastening element (7) form a common primary threaded connection (18) to frictionally and electrically connect the first electrical conductor (2) to the second electrical conductor (3) in a screwed-together state. The first fastening element (6) further has a mechanical connection interface (13) for a captive connection to the first electrical conductor (2).

A device includes a tensioning member including a head portion and a cylindrical portion. The head portion includes a first bore and a second bore in communication with the first bore. The cylindrical portion extends from the head portion towards a second end and includes one or more threads. A device may include a set screw member including threads formed along its length. The set screw member may couple to the first bore and retains an electrical conductor positioned in the second bore in connected engagement with the tensioning member. The tensioning member is configured to contact an elongate article to electrically connect the elongate article to the tensioning member and the electrical conductor. A device may also include a strap member. The strap member extends around the elongate article and the tensioning member applies a tension force between the strap member and the elongate article.

A connector assembly for battery modules of an electric vehicle includes a connector element and a counterpart arranged to be mutually connected in an electrically conductive manner. The connector element includes a protective casing having an outer collar configured for coupling with the counterpart. The connector assembly includes an electrical connection unit having opposite ends adapted for electrically connecting two connector assemblies positioned on respective battery modules. The connector assembly includes a fastening unit comprising a connection screw axially positioned within the outer collar and engaged with the counterpart, an integrated sealing system to prevent water infiltration into the connector element or the counterpart, and a locking ring to lock in position the screw inserted inside the outer collar even when not fixed to the counterpart. The locking ring comprises at least one locking flange cooperating with a locking shoulder formed along the inner surface of the outer collar.

The objective is to improve the electrical conductivity and heat conductivity at the connection part of the busbars while suppressing the loosening of bolts. The busbar connection structure includes a terminal block body, a fastening part, a fastened base, a bolt, grease, and a thread locking member. The fastening part fastens the terminal block body to the cooling section. The fastened base is attached to the terminal block body and includes a thread hole. The bolt fastens the connection part of the busbars to the fastened base. The grease is electrically conductive and is applied at the connection part of the busbars. The thread locking member is interposed between the outer circumferential surface of the bolt and the inner circumferential surface of the thread hole, and suppresses the loosening of the bolt by biting into the outer and inner circumferential surfaces.

A charging connector that facilitates a routing operation of an electric cable and is unlikely to cause contact failure between a connection terminal and an electric cable is provided. The charging connector has a housing having socket portions extending along an axial direction, connection terminals accommodated in terminal receptacle portions formed radially inward of the socket portions, and a rotation regulator structure operable to regulate rotation of the connection terminals about their axes with respect to the socket portions. The connection terminal includes a plug connection portion to which a terminal of the charging plug can be connected and a terminal coupling portion located at an opposite side of the plug connection portion in the axial direction. The fixture terminal is coupled to the terminal coupling portion. The rotation regulator structure includes terminal engagement portions formed in the connection terminal and socket engagement portions formed on the socket portions.
