A bus duct socket device

Abstract

The invention discloses a bus duct jack device which relates to the field of low-voltage power transmission and distribution technology. The bus duct jack device comprises a through and an insulating bracket which is mounted in the trough. A plurality of bus mounting troughs are equidistantly arranged on the insulating bracket. Each bus mounting trough is internally provided with a bus. An insulator is mounted between two adjacent buses. Two sides of the bus are provided with insulated elastic clamping pieces. Furthermore the lower end of each elastic clamping piece is fixed on the insulator. Each bus is provided with a Y-shaped pin in a clamped manner. The Y-shaped pin is inserted between the elastic clamping pieces and the bus. A pin block is arranged above the Y-shaped pin. The bus duct jack device has advantages of high stability, high reliability and effective prevention for contact failure.

Description

technical field

[0001] The invention relates to the technical field of low-voltage power transmission and distribution, in particular to a bus duct socket device. Background technique

[0002] Due to the structure of the existing bus duct socket, the copper pins are not directly inserted outside the copper pins corresponding to the phase sequence during the plugging process of the bus main line current and the plug box, so the contact resistance is large and the overload capacity is low. Copper and aluminum materials are directly over-plated, which increases the temperature rise. Due to the different hardness of copper and aluminum materials, the number of times of plugging and unplugging between the two cannot meet the standards and usage requirements. Because the temperature rise of the pins exceeds the standard, it will cause a short circuit, and in severe cases, it will even cause a failure to burn the device. Therefore, need a kind of good stability, safe and reliable...
