Abstract: An insulating housing with integrated functions comprises a barrel-shaped shell, an interior wall of which being provided with a protruded or recessed uneven texture configured to increase a creepage distance between both axial ends of the barrel-shaped shell, the path of the creepage distance formed by the protruded or recessed uneven texture having more than two flyover or bypass sub-paths, such that the creepage distance is increased, and the voltage withstanding is increased. Meanwhile, by employing a construction of creepage-increasing rings, not only the creepage distance is increased greatly, but also the barrel-shaped shell is avoided from full-interior wall contamination by metal vapor evapotranspiration.

Abstract: The present invention relates to a vacuum switch tube, which includes a first contact and a second contact disposed on conductive rods respectively. The two contacts are disposed facing each other. The two contacts are cylinders and include conductive members and magnetic members to form contact bodies. The cross section shape of the magnetic members is divided by a neutrality line into two unequal regions. The magnetic member of the first contact and the conductive member of the second contact are disposed corresponding to each other. The conductive member of the first contact and the magnetic member of the second contact are disposed corresponding to each other. The two vacuum switch contacts are anti-symmetrically disposed, such that a rotating magnetic field having rotating lines of magnetic force is formed, so that re-ignition possibility during voltage breaking is effectively reduced, and an arc voltage is decreased.

Abstract: The present invention relates to a vacuum switch tube, which includes a first conductive rod and a second conductive rod. A first contact is disposed at the first conductive rod. A second contact is disposed at the second conductive rod. The first contact and the second contact include conductive members and magnetic members, and are sealed in a vacuum tube body and correspondingly disposed. A front end of the first contact is disposed with a convex hemisphere. A front end of the second contact is disposed with a concave hemisphere matching with the front end of the first contact in shape. Therefore, the vacuum switch tube increases surface areas of the contacts, and reduces a resistance increase caused by the poor contacting effect. Meanwhile, a rotating magnetic field is formed between the convex hemisphere and concave hemisphere contacts, thereby facilitating arc-extinguishing and enhancing a breaking capability.
