[0069] Figure 5 A schematic cross-sectional view of an electrical connection device according to a second exemplary embodiment of the present invention is shown.

[0070] and figure 1 Compared to the first embodiment shown, the Figure 5 The main difference of the second embodiment shown is: not only at least one first threaded through hole 31 is formed in the first raised portion 30c of the first conductive half body 30, but also at least one first threaded through hole 31 is formed in the second conductive half body 40 At least one second threaded through hole 41 is formed in the second protrusion portion 40c. Simultaneously, in the first threaded through hole 31 and the second threaded through hole 41, screw in the bolt 51 and the bolt 52 respectively, like this, the bolt 51 and the bolt 52 just can push the first conductor on the direction F1, F2 that separates from each other simultaneously. half body 30 and the second conductive half body 40 .

[0072] Figure 6 A schematic perspective view of the first conductive semi-body of the electrical connection device according to the third exemplary embodiment of the present invention is shown.

[0073] and Figure 1-Figure 5 Compared with the first and second embodiments shown, the Figure 6 The main difference of the third embodiment shown is that: the first insertion end and the second insertion end of the first conductive half body 30 are no longer semicircular cylinders, but at least two concentric fan-shaped cylinders separated from each other .

[0074] Such as Figure 6 As shown, one insertion end of the first conductive semi-body 30 includes two concentric fan-shaped cylinders 30a1 and 30a2 spaced apart from each other. Similarly, the other insertion end of the first conductive half body 30 includes two concentric fan-shaped cylinders 30b1 and 30b2 spaced apart from each other. The advantage of adopting this structure is that the contact force and bonding force ...

Abstract

The invention discloses an electric connecting device electrically connected with a tubular bus. The electric connecting device comprises a first conductive half body with a first insertion end, a second conductive half body with a second insertion end, and an expansion device. The expansion device is used for extruding the first insertion end and the second insertion end inserted into the tubular bus to the inner wall of the tubular bus towards mutually separated directions under predetermined expansion force, so that the outer walls of the first insertion end and the second insertion end are tightly jointed with the tubular bus, wherein, the expansion device comprises a threaded through hole formed in a raised part of at least one of the first and second conductive half bodies and a bolt screwed into the threaded through hole, and the bolt pushes the first conductive half body and the second conductive half body towards the mutually separated directions. Compared with the prior art, the electric connecting device has the advantages that the electric connecting device is convenient to install, the bus is not required to be machined, the electric connecting device can be installed only by using a screw wrench, special training for installation workers is not required, and special installation tools are also not required.

Description

technical field [0001] The invention relates to an electrical connection device, in particular to a connection device for electrical connection with a tubular busbar, especially suitable for electrical connection with a large cross-section tubular busbar. Background technique [0002] In various high-voltage places such as power plants, distribution substations, and large-scale industrial and mining fields, tubular busbars that transmit power frequency and high currents are required. This high-voltage tubular busbar has a large cross-section. In the prior art, for the connection operation of such a large cross-section high-pressure tubular busbar, the following three traditional connection methods are generally adopted: [0003] 1) Hoop connection method [0004] The hoop connection method hugs the tubular busbar from the outside. The mechanical structure is complex, the size is large, and the shape is irregular. The outer covering shielding layer is not firm, and it is not...
