AI Technical Summary

Benefits of technology

This technology uses columns instead of traditional methods like buttons or levers for connecting electronic devices together with wires that allow them to work properly even when there's only one thing inside it. Additionally, this method allows for better alignment between contacts on different parts of an device without requiring extra effort from outside sources such as pliers or screwdriven connections. Overall, these technical improvements make electrical connectors more reliable while also being easier to use than older ways they were designed earlier.

Problems solved by technology

Technological Problem addressed by existing low voltage knifter switch designs involves improving their electrical connection between parts that come into physical proximity during normal usage conditions without causing damage or malfunctions over time caused by external factors such as vibrations from machinery.

Abstract

The invention discloses a radian column matched low-voltage knife switch which comprises a knife body and a supporting body. The supporting body comprises an insulating column and insulating boards fixedly connected with the insulating column. Sleeve type contact seats are arranged on the insulating boards. The knife body is provided with contacts matched with the sleeve type contact seats in position and radian. Insulating rubber is arranged between the contacts and fixed between knife body clamping boards and abuts against the contacts. The contacts are connected with electrified seats. Pull rings are further arranged on the knife body clamping boards. The radian column matched low-voltage knife switch has the advantages that due to the adoption of column contact, external pressure is not needed, and good contact can be guaranteed depending on the size match of the contacts and the contact seats which are reserved when a product is designed; in addition, due to the adoption of column contact, the contact area is increased compared with that of plane contact, and stability of the contact performance is further guaranteed.
