A connection terminal for the electrically contacting connection of a conductor to a current bar which is accommodated on a holder includes a clamping spring having a first limb and a second limb, said clamping spring being provided for applying a clamping force for damping the conductor. An actuation device which comprises the clamping spring is provided. Between the first limb and the second limb of the clamping spring, which is in the form of a tension spring, is arranged an insert device which provides a counter-bearing for a tool when the actuation device is actuated.

An electrical connector includes a housing and a conductive contact member disposed in the housing. A first contact portion of the conductive contact member receives a blade contact of an electrical device and a second contact portion electrically engages an inserted electrical wire. A spring member is disposed in the housing and is connected to the contact member. A rotatable member is movable between first and second positions. When the rotatable member is in the second position the spring member secures an inserted wire in electrical engagement with the conductive contact member and prevents removal of the inserted wire. When the rotatable member is in the first position the spring member allows for removal of an inserted wire and allows for insertion of a wire in the housing.

A connector includes a pushing member having a projection, a support member disposed to contact a lateral surface of the projection, and a contact made of a conductive material and having a support member facing portion facing the support member, a part of the flexible conductor being disposed between the support member and the support member facing portion of the contact, the lateral surface of the projection pressing the part of the flexible conductor against the support member facing portion of the contact via the support member, whereby the contact is electrically connected to the flexible conductor.

A method of manufacturing a board-to-board connector capable of preventing a short-circuit from occurring between contacts when connectors are fitted to each other. Pin-shaped male-side contact portions protrude from one surface of a male-side insulating film, and male-side terminal portions are provided on the other surface of said male-side insulating film. This makes it possible to prevent a short-circuit from occurring between adjacent female-side contacts by the male-side contacts.

A wedge cartouche (1) for use with at least one line (3) and corresponding containment assembly (5). The wedge cartouche (1) includes at least one wedging 5 component (7) being positioned, shaped and sized for inserting inside the containment assembly (5), adjacent to the at least one line having a segment (9) extending through said containment assembly (5), the at least one wedging component (7) being moveable along at least one given path (11), and being operable between opposite drawn-in and drawn-out configurations along said at 10 least one given path (11). The wedge cartouche (1) also includes and a blasting assembly (13) for propelling the at least one wedging component (7) into the drawn-out configuration, in order to operatively secure the segment (9) of the at least one line (3) between a receiving portion (15) of the containment assembly (5) and said at least one drawn-out wedging component (7). 15

An electrical connector includes two pads having the same shape. Each pad has a connector body with a first groove, a second groove, and a hole. The hole extends through the connector body between the first groove and the second groove. A fastener extends through the hole of both of the two pads so that the two pads having the same shape are connected to one another and are pivotable around the fastener relative to one another with the two first grooves contacting a first conductor when the first conductor is in an installed position and the two second grooves contacting a second conductor when the second conductor is in an installed position. A spring is between a first end of the fastener and one of the two pads having the same shape so that the spring biases the two pads having the same shape towards each other.

Contact system for producing an electrically conductive contact between an aluminum conductor (3) and a contact component (2). A housing (1) is provided, as well as a contact component (2) having a shearing section (13) and a tapered compression segment (14), where the housing (1) has an insertion volume (4) for the aluminum conductor (3) and an insertion volume (5) for the contact component (2) and the two insertion volumes (4, 5) overlap within the housing (1) and form a common overlapping volume (8) so as to enable, when the aluminum conductor (3) has been pushed into the insertion volume (4), for the aluminum conductor (3), the severing/shearing and cold welding of the aluminum conductor (3) with the contact component (2) by means of the contact component (2).

This disclosure addresses the problem of aluminum and in particular stranded aluminum wires, which generally do not well bond to other metals such as e.g. copper or brass. In the long term, transition resistance changes, in particular under the influence of oxygen and due to the energizing with high currents. There is also a need for high-current connectors that can be flexibly strapped and field-wired. This disclosure provides a heavy-duty plug-type connector having at least one crimp contact, the transition between a crimping region formed of aluminum and a contact region formed of copper being shifted to the cylindrical or at least rotationally symmetric crimp contact. The stranded wire can thus be crimped with the crimp contact without the aforementioned problems. Furthermore, an additional inner thread and a pin that the can screwed into it are provided in the crimping region.

A busbar connection system comprises a plate member formed of a first material having a higher tensile strength than second and third materials of first and second busbars, respectively, and defining first and second apertures and first and second stud members securely inserted through the first and second apertures of the plate member, respectively, the first and second stud members being configured to be securely inserted through first and second apertures, respectively, in each of the first and second busbars, wherein the first and second stud members mitigate rotational movement between the first and second busbars when connected.

A polarized battery clamp includes a contact handle with an internal electrical path connecting a handle electrical connector at one end of the contact handle to a terminal contact pad at a second handle end, the contact handle also having an internal electrical contact bus connected to the electrical connector; and a contact arm having a terminal contact pad at a first arm end and a stepped pivot pin at a second arm end, the contact arm also having an electrical conductor electrically connected to the arm terminal contact pad; wherein the electrical conductor is placed into electrical contact with the electrical contact bus by inserting the stepped pivot pin into a handle positional slot.
