Description

Electrical connection device

The present invention relates to a connection structure, and in particular to a connection structure for connecting a power transmission bus.

In the construction of large-scale factories or high-tech factories, setting up stable and safe power is a key to the operation of machines or equipment in the factory. Compared with setting up cables, setting up power transmission busbars has better space utilization and safety. Therefore, power transmission busses that can transmit large amounts of power are now mostly used to replace traditional cables.

When laying out a power transmission bus, different segments of the power transmission bus need to be connected to each other. When the power transmission bus needs to be laid out over a larger area, the number of power transmission busses that need to be connected will also increase. If the installation method of the connection structure connecting the two power transmission bus bars is too complicated, it will extend the work hours and increase the installation cost. In addition, if the connection structure is poorly designed, the resistance at the connection will increase or the contact will be poor, resulting in power loss and heat generation.

In summary, how to save the time of connecting the power transmission bus and reduce the complexity of the connection structure will also be the research goal of the connection structure of the power transmission bus.

One object of the present invention is to provide a connection structure that is easy to install and avoids excessive resistance differences at the connection points.

The invention provides an electrical connection device, which includes a first pressing plate, a second pressing plate and a power bridge part. The second pressure plate is arranged opposite to the first pressure plate. The power bridge is disposed between the first pressure plate and the second pressure plate. The power bridging part includes an insulating structural member and a first bridging piece. The first bridge piece is disposed on the first surface of the insulating structural member, wherein the first bridge piece is electrically coupled to the first conductor piece and the second conductor piece. The first pressure plate and the second pressure plate provide compressive stress to the power bridge portion through the fixing member.

As mentioned above, the first pressure plate and the second pressure plate provide compressive stress to the power bridge portion through the fixing member. The first conductor piece and the second conductor piece are electrically coupled through the first bridge piece in the power bridge portion, so that power can be transmitted from the first conductor piece to the second conductor piece. In order to achieve the purpose of easy installation and avoid excessive resistance differences at the connections.
