Bus plugging box with very high stability

Abstract

The invention discloses a bus plugging box with very high stability, comprising a box body. The back of the box body is provided with a plurality of interfaces, and a plurality of pins are arranged on each of the interfaces. Each pin comprises a center copper column, the lower end of the center copper column is provided with a fixing and bonding mechanism, the fixing and bonding mechanism comprises two bonding plates, and each bonding plate is composed of a first fixing part, an arc part, a second fixing part, and a tip bonding part. Two clamping patches are arranged at the two ends of the lower part of each center copper column, the two clamping patches are respectively arranged at the two sides of the corresponding fixing and bonding mechanism, the two clamping patches are arranged in axial symmetry with the corresponding fixing and bonding mechanism as the axis of symmetry, and the two clamping patches firmly contact a copper bar in use. The bus plugging box has very high stability. Moreover, each pin is provided with a radiating cavity, which improves the radiating effect and increases the safety performance.

Description

technical field [0001] The invention relates to a busbar plug-in box with extremely high stability. Background technique [0002] The busway system is a power distribution device that efficiently transmits current, and is widely used in the power distribution system of high-rise buildings and large-scale factories. The plug-in box is a part of the bus duct. When in use, the pins of the bus duct plug-in box are erected, and the lower end of the pin of the bus duct plug-in box clamps the copper bar, so that the lower end of the bus duct plug-in box pins is in contact with the copper bar; Some busway plug-in box pins have disadvantages after long-term use: the lower end of the busway plug-in box pins is not in tight contact with the copper bar, and the contact between the lower end of the busway plug-in box pins and the copper bar is more difficult after long-term use If it is not tight or firm, it will become loose, the stability is poor, and it is easy to shift and skew.

The plug-in box is a part of the bus duct. When in use, the pins of the bus duct plug-in box are erected, and the lower end of the pin of the bus duct plug-in box clamps the copper bar, so that the lower end of the bus duct plug-in box pins is in contact with the copper bar; Some busway plug-in box pins have disadvantages after long-term use: the lower end of the busway plug-in box pins is not in tight contact with the copper bar, and the contact between the lower end of the busway plug-in box pins and the copper bar is more difficult after long-term use If it is not tight or firm, there will be looseness, poor stability, and easy to shift and skew

Moreover, because the pins of the existing busbars are closely attached to the busbars, it often leads to poor heat dissipation, and it is easy to cause a short circuit due to excessive temperature rise of the pins. In severe cases, it may even cause equipment to burn out, increasing potential safety hazards.
