An electrical connection device including a support and an electrically conductive terminal lug, wherein the support includes a first face, with channels projecting from a second face opposite from the first face and defining between them a housing; the terminal lug includes a base for placing in the housing and a shank fastened coaxially to the base, the base including a first face from which the shank extends and a second face opposite from the first face for coming to bear against the second face of the support; the terminal lug including a locking ring having the shank passing through its center and movable in rotation relative to the shank, the ring including ramps extending from the outer periphery of the ring, the ramps co-operating with the channels.

A coupler (100; 100) between a first coaxial connector and a coaxial cable (10) has a first coaxial connector with an inner conductor (2), at least one hollow cylindrical insulator part (27; 271, 272) and a hollow cylindrical outer conductor (1) and a first spring sleeve (9) for accommodating an outer conductor (11) of the coaxial cable (10), which spring sleeve is connected to the outer conductor (1) of the first coaxial connector. In addition, the coupler (100; 100) in accordance with the invention has a locking device, which is axially movable relative to a longitudinal axis of the first coaxial connector and is supported on a conically realized outer surface (20) at a distal end of the first spring sleeve (9). The outer conductor (1) of the first coaxial connector is connected to the locking device via a bayonet connection.

The invention relates to an electric device, especially to a connecting rod, said connecting rod comprises a conductive first column portion that has an interference fit with a busbar, said first column portion axially arranges a conductive second column portion which has an interference fit with said first column portion, said second column portion is located inside of said first column portion, a thermal expansion coefficient of said second column portion is greater than that of said first column portion. Said transformer has such advantageous effects, 1. the same overlapping length increases more conductive surface for reducing a current density to achieve low temperature rising of connecting part; 2. amount of material is reduced and save the social source; 3. the electric clearance or safety distance is increased, an electric safety of device is also increased; 4. a width of a connecting part is reduced, an occupation space of transformer is also reduced.

The invention relates to a fastening bolt (10, 10) comprising a fastening bolt head and a fastening bolt shank (13).
