Plug and socket combining device of illuminating bus slot

Abstract

The invention discloses a plug and socket combining device of an illuminating bus slot. A socket seat of a socket device is fixed into a slot body; the upper surface of the slot body is provided witha sliding door seat; the sliding door seat and the socket seat form a fixing device; the top of the sliding door seat is fixed with a sliding door cover; an upper cover and a lower cover of a plug device are arranged on the upper part of the sliding door cover; copper sheet pins are fixed into the lower cover; both sides of the upper cover and the lower cover are respectively fixed with a side ear; a torsional spring is arranged between the upper part of each side ear and the lower cover; a central hole of the torsional spring is fixed by a bolt; the upper end of each side ear is higher than the upper cover, and the lower end of each side ear is clamped in the corresponding concave position of the slot body. The socket device avoids influencing the plug contact effect due to temperature rise in using a daily plug, enhances the connection fastness and reliability and has high protecting grade.

Description

technical field [0001] The invention belongs to a low-voltage electrical power distribution device, in particular to a plug and socket combination device for lighting bus ducts leading to a power supply, which provides feeder branches and protection for electric equipment such as lamps. Background technique [0002] In the traditional lighting busbar structure, to take power from the main line unit, the copper sheet is generally clamped on the copper wire by using a ∏-shaped reed, and the contact between the hard wire and the branch unit is realized by the elasticity of the manganese steel sheet itself. Bridge connection is easy to deform at room temperature, and the contact effect is not good, resulting in a high temperature rise in the contact part of the branch unit and the busbar, which poses a safety hazard; in addition, because the plug uses ∏-type pins, the insulation protection level of the plug branch unit is affected. Here comes the difficulty. Contents of the in...
