Wire holder

Abstract

The invention relates to a wire holder. The wire holder comprises a base, a wiring board, multiple lug plates, a wire pressing plate and a wire pressing fastening piece, wherein the wiring board is arranged at the bottom part of the base; the multiple lug plates are arranged at the top part of the base, are mutually isolated and are connected with the wiring board by penetrating through the base; and the wire pressing fastening piece penetrates through the lug plates and is in threaded connection with the lug plates. According to the wire holder disclosed by the invention, the lug plates are connected with the wiring board by penetrating through the base, the wire pressing fastening piece is in threaded connection with the lug plates after penetrating through the lug plates, the lug plates can be tightly pressed by tightly screwing the wire pressing fastening piece, thus a connecting wire can be stably and tightly pressed on a connecting plate by the lug plates, the wiring can be finished, the wiring is simple, firm and reliable, the wiring and the disconnecting are fast and convenient, the anti-shock ability is strong, the anti-loosing performance is excellent, the creep age distance and the electric clearance are extremely low, the interference and the radiation to outside world can be ignored, the wire holder is safe and reliable, the violent vibration requirement of the lamp ship inspection GD01-2006 can be completely met by the wire holder according to determination, and the anti-explosion electric performance requirement is accordant.

Description

【Technical field】 [0001] The invention relates to a circuit conversion device, in particular to a terminal block. 【Background technique】 [0002] At present, the country has clear requirements for explosion-proof electrical equipment used in explosive environments, such as the GD01-2006 standard. Explosion-proof lamps have high standards for wire connection, creepage distance and electrical clearance. When explosion-proof lamps are connected to terminal blocks, due to the poor shock resistance of traditional terminal blocks, they cannot meet the performance requirements of explosion-proof electrical equipment, especially in military and marine environments with severe vibrations. At the same time, it cannot meet the high requirements for electrical interference and radiation, and does not meet the requirements for explosion-proof electrical performance. 【Content of invention】 [0003] In view of this, it is necessary to provide a terminal block with strong shock resistan...

AI Technical Summary

Problems solved by technology

When the explosion-proof lamps are connected to the terminal block, due to the poor shock resistance of the traditional terminal block, they cannot meet the performance requirements of explosion-proof electrical equipment, especially in military and marine environments with severe vibrations.

At the same time, it cannot meet the high requirements for electrical interference and radiation, and does not meet the requirements for explosion-proof electrical performance.
