A clamp for a male terminal of a power source, the terminal including a frustoconical body projecting out of a base surface that is part of the source against which a greatest diameter of the terminal rests, may include: at least one ring-shaped first portion, with an open section of its circumference, the at least one first portion having a first diameter such that a predetermined radial clearance exists when the at least one first portion axially fits upon the frustoconical body, the at least one first portion also having two jaws which axially project out of the circumference of the at least one first portion, the jaws being in opposed, spaced-apart relationship; and a clamping device which acts on the jaws and is configured to move the first jaws toward each other to tighten the at least one first portion around the frustoconical body with elimination of the clearance.

A connection module includes a first bus bar, a second bus bar and a connection unit. The connection unit includes a housing case having an insulation property and having a housing space formed therein, and a fastening member disposed inside the housing space. The connection unit is provided with a tool insertion hole through which a tool to be attached to the fastening member is insertable. The fastening member is configured to electrically connect the first bus bar and the second bus bar that are disposed inside the housing space. An insulation member is disposed in a portion of the fastening member that is visible through the tool insertion hole when the fastening member is seen through the tool insertion hole.

An interconnect is disclosed that opens a battery circuit when an access cover is removed. The interconnect includes a single installed position, and does not include any throw positions to avoid ambiguity. The interconnect includes a conductive element that closes the battery circuit when the interconnect is installed. The access cover cannot be removed when the interconnect is installed, because the interconnect includes at least one mechanical feature that prevents removal of the access cover. In some instances, the interconnect is integrated into the access cover, such that when the cover is removed, the circuit is opened necessarily during removal. The interconnect interface may include blades, pins, or other electrically conducting elements. The interconnect is arranged in the battery system away from power electronics and other components that may interface to an electrical load, thus providing an added measure of safety when the access cover is off.

A clamp for providing an electrical connection to a battery includes a first arm, a second arm, a joint member, a first pivotable connection, and a second pivotable connection. The first arm includes a proximal end, a distal end, and an electrically conductive member at the distal end. The second arm includes a proximal end and a distal end. The first pivotable connection is between the joint member and the first arm, and defines a first axis, about which the first arm rotates relative to the joint member. The second pivotable connection is between the joint member and the second arm, and defines a second axis, about which the second arm rotates relative to the joint member. The first and second axes are displaced from each other in a direction that is perpendicular to the first axis.

A conductor module includes a wiring member, a plurality of bus bars, a plurality of locking pieces, and a reinforcing member. A plurality of wirings and through-holes are formed in the wiring member. The bus bar is electrically connected to one of two electrode terminals. The two through-holes are formed in a first opposing region opposing one end face between both end faces of the bus bar opposing each other in a width direction with an electrical connection portion where the bus bar and the wiring are electrically connected interposed therebetween. The locking piece is formed integrally with the bus bar, is arranged in the through-hole, has a distal end positioned radially outward of the through-hole, and fixes the bus bar to the wiring member. The reinforcing member reinforces the wiring member, and is formed to surround the through-hole.

A connection module includes a first bus bar, a second bus bar and a connection unit. The connection unit includes a housing case having an insulation property and having a housing space formed therein, and a fastening member disposed inside the housing space. The connection unit is provided with a tool insertion hole through which a tool to be attached to the fastening member is insertable. The fastening member is configured to electrically connect the first bus bar and the second bus bar that are disposed inside the housing space. An insulation member is disposed in a portion of the fastening member that is visible through the tool insertion hole when the fastening member is seen through the tool insertion hole.

A cooling lance is provided to cool an electrically conductive contact body. The cooling lance includes a lance body, a fluid line extending through the lance body, and a flexible cooling bladder positioned on an end of the lance body and in fluidic communication with the fluid line.

A connector assembly includes an installation seat having a pair of first installation holes and a second installation hole, a pair of first connectors respectively detachably inserted into the first installation holes, and a second connector detachably inserted into the second installation hole. Each of the first connectors has a power terminal. The second connector has a signal terminal and a grounding terminal.

Method for establishing a connection between an electrical connecting element for a motor vehicle on-board network and a cable of the motor vehicle on-board network in which the cable (2) is provided with a metallic stranded conductor (4), firstly the metallic stranded conductor is mechanically compacted in such a way that a flat area is formed, whereby during the compacting, a material bond is formed between strands of the stranded conductor (4), and subsequently, the connecting element is connected to the flat region in a material bond.
