A terminal 12 connected to a front end portion of an electric cable 11 in the extension direction thereof is provided with a terminal main body 15 sandwiching the electric cable 11, and a slide member 16 which is capable of sliding relative to the terminal main body 15 in the extension direction of the electric cable 11. The terminal main body 15 includes a sandwiching portion 19 which is formed by means of a machined metal sheet material 60 and which sandwiches the electric cable 11, wherein: the sandwiching portion 19 includes a first holding projecting portion 23B which is formed by folding over the metal sheet material 60 at a side edge thereof that intersects the extension direction of the electric cable 11, and which projects out toward the electric cable 11 and is in contact with the electric cable 11, and a second holding projecting portion 23C which is formed by folding over the metal sheet material 60 at a side edge thereof in the extension direction of the electric cable 11, in such a way as to be positioned forward of the first holding projecting portion 23B in the extension direction of the electric cable 11, and which projects out toward the electric cable 11 and is in contact with the electric cable 11; and the slide member 16 includes a pressing portion which presses the sandwiching portion 19 toward the electric cable 11.

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.

An operation method for busbars docking platform has putting a first busbar and a loading unit in a receiving groove, arranging the first busbar to touch the loading unit, removing the loading unit; loading a connecting rod to the loading unit; putting the loading unit in the receiving groove; triggering the first release member to impact the loading unit; triggering the second release member to retract the action unit; removing the loading unit; putting a second busbar in the receiving groove; putting the first busbar between the action unit and the second busbar; removing the first busbar; putting the first busbar in the receiving groove; triggering the first release member to impact the first busbar; triggering the second release member to retract the action unit; and taking the first busbar and the second busbar out from the receiving groove.

A platform for connecting busbars has a loading unit having a blind hole on a docking surface for receiving a connecting rod, an action unit used for impacting the loading unit or a busbar to push the connecting rod into a pre-hole on the busbar, a limit unit used for stopping the busbar from moving along its length direction, and a support unit used for supporting the action unit and the limit unit. The connecting rod is assembled to the first busbar by the action unit combined the loading unit and then the connecting rod already assembled to the first busbar is assembled to the second busbar by the action unit.

An electrical coupling for making a secure and reliable connection between a frayed end of one or more wires. The electrical coupling comprises a terminal, a casing, a conical portion, and a threading portion. The electrical coupling is configured to receive and squeeze down the frayed end of the one or more wires due to the tapering and narrowing shape of the conical portion within an inner sidewall between a first inner diameter and a second inner diameter. The conical portion comprises a side wall. The side wall is configured to taper in from a first end to a second end to form a conical shape. The conical portion comprises a first open end having the first inner diameter.
