Scalable contact conductive connection device

Abstract

A scalable contact conductive connection device comprises an insulating base; the upper surface of the insulating base is connected with a conductive connection unit; the conductive connection unit comprises a trigger and a conductor, wherein at least one conoid contact is arranged at the top end of the trigger; an arc strike is arranged at the top end of the contact; a spring is arranged in the middle of the trigger; the upper end of the spring is connected with a cylinder; the spring is driven to stretch out and draw back through the stretching out and drawing back of the cylinder to enable a scalable contact to be in a retracted state; a connecting conducting wire is arranged in the trigger; a thread is fixedly formed in the lower part of the trigger; and the conductor is directly connected with the trigger in a contact manner. According to the conductive connection device, through arrangement of the insulating base, breakover of the conductor on the insulating base can be ensured; meanwhile, through the insulating base, a conductive article is unlikely to realize entire breakover, and the base made of a polymer composite material is high-temperature-resistant and corrosion-resistant; and the spring is arranged in the middle of the trigger to ensure stable contact, so that the conductive connection device is not only high in applicability, safe and reliable, but also has a certain flexibility, and is long in service life.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a conductive connection device for a retractable contact. Background technique [0002] No matter what kind of conductive equipment, their performance is affected by contact material, voltage and current value, type of load, and temperature environment. Failure to meet predetermined values ​​for any of these factors can cause problems such as contact welding, wear, or a rapid increase in contact resistance. Because the large current passing through the contacts will easily cause damage to the conduction of the contacts, and the continuous conduction of the conductive equipment cannot be guaranteed. [0003] At the same time, the connection points of current conductive equipment are generally plug-type or adsorption-type, and the exposed contact points of the connected equipment are always connected to the internal components. If water or liquid touches the contacts...

AI Technical Summary

Problems solved by technology

Failure of any of these factors to meet predetermined values ​​can lead to problems such as contact welding, wear, or rapid increase in contact resistance

Because the large current passing through the contact point will easily cause damage to the contact conduction, and the continuous conduction of the conductive device cannot be guaranteed.

[0003] At the same time, the connection points of current conductive equipment are generally plug-type or adsorption-type, and the exposed contact points of the connected equipment are always connected to the internal components. If water or liquid touches the contacts, it will cause a short circuit of the internal components, resulting in equipment damage
