Blade spring type power current inserting-connecting device

Abstract

The invention relates to a blade spring type power current inserting-connecting device, which belongs to the technical field of power cable inserting-connecting devices in coal mines and is applied to coal mine electric accessories for power cable quick connection. The adopted technical scheme is that the blade spring type power current inserting-connecting device comprises a female connector and a male connector, the female connector is a hollow cylindrical metal pipe, the hole diameter at the front end of the metal pipe is smaller than that in the middle of the metal pipe, a blade spring is installed on the inner wall of the metal pipe, the blade spring is an elastic metal sheet which is folded in the saw-toothed shape, and the blade spring is installed by being bended into a pipe shape along the inner wall of the metal pipe of the female connector. The male connector is a columnar metal rod, the front end of the male connector is a small cylinder matched with the inner wall of the metal pipe of the female connector, and an axial hole is arranged on the end face at the back end of the male connector. The blade spring type power current inserting-connecting device is suitable for the fields of coal mines, factories and the like.

Description

technical field [0001] The invention discloses a leaf spring type power current plugging device, which belongs to the technical field of power cable plugging devices in coal mines. Background technique [0002] At present, the electrical equipment in coal mines in my country generally adopts the fixed cable connection type. Once an electromechanical failure occurs, it is difficult to deal with it. It takes a long time to eliminate the problem, and it is not easy to replace it. Hidden danger; the connection point between cables or wires and electrical equipment usually uses cable connectors, commonly known as wire lugs. The connection is reliable. After the connection, the electrical equipment is fixed with the cable, but the wiring and disassembly are troublesome and time-consuming; this cannot be applied in many occasions that require fast connection, especially in some unitized and assembled electrical equipment. There are many terminals and frequent connections and disconne...

[0002] At present, the electrical equipment in coal mines in my country generally adopts the fixed cable connection type. Once an electromechanical failure occurs, it is difficult to deal with it. It takes a long time to eliminate the problem, and it is not easy to replace it. Hidden danger; the connection point between cables or wires and electrical equipment usually uses cable connectors, commonly known as wire lugs. The connection is reliable. After the connection, the electrical equipment is fixed with the cable, but the wiring and disassembly are troublesome and time-consuming; this cannot be applied in many occasions that require fast connection, especially in some unitized and assembled electrical equipment. There are many terminals and frequent connections and disconnections. A wiring device that can quickly connect wires is needed. For coal mines whose production is calculated in minutes, every minute of electromechanical failure time is a waste of production and a hidden danger to safety.
