Problems solved by technology

However, due to the structural design of the existing electrical connections, in actual use, many of the joints are in the state of point contact and line contact, such as Figure 4 As shown, the local contact point provides a long current path and current carrying capacity, which gradually increases the contact resistance and eventually leads to failure.

Embodiment Construction

[0016] The electrical connector is composed of an outer taper sleeve joint 9 and an inner taper sleeve joint 7. The contact surface between the inner and outer taper sleeves is a tapered surface. The inner taper sleeve joint 7 is provided with an internal thread. The inner taper sleeve joint 7 uses the thread and The connecting piece of external thread is connected, and the outer taper sleeve joint 9 is sleeved on the outside of the inner taper sleeve joint 7 and fastened together by a nut 11 matched with the connecting piece. This kind of tapered surface will become tighter and tighter when the screw is used to tighten, so that the entire electrical surface is in close contact with the whole, so that the length of the current flow line can be shortened, the current distribution is more uniform and comprehensive, and the contact caused by contact is completely eliminated. Potential accidents such as heat generation of the joints caused by defects, and improve the safety of electri...

Abstract

The invention refers to a kind of electric connection technology, which concretely refers to a technology using a cone to realize the electric connection. According to the design project in the invention, it is made up of an outer taper sleeve connector and an inner taper sleeve connector, and, the contacting surface between the two sleeves is a cone surface. There sets an inner screw in the taper sleeve connector, the inner taper sleeve connector uses the screw to connect with the connectors which has outer screw, and the outer taper sleeve connector is covered out of the inner taper sleeve connectors, and is fixed together with the nut matching with the connectors. The invention upgrades the connecting performance of electric connection, reduces the occurrence of failure.

Description

Technical field [0001] The present invention relates to electrical connection technology, in particular to a technology that uses a tapered surface to realize electrical connection. Background technique [0002] As an intermediate link in the process of power energy consumption, the electrical equipment in operation is the basic component of the power system. Once a failure occurs, it will inevitably cause a partial or even a regional power outage, causing huge economic losses and adverse social impacts. . The powerful electricity produced by the power plant is sent to power users through facilities such as step-up substations, transmission lines, step-down substations, and high-voltage distribution lines. The connections between electrical equipment and conductors, conductors and wires, and transmission and distribution lines themselves in these power distribution devices are all inseparable from electrical connections. [0003] The main forms of electrical connection include ma...
