Example Embodiment

[0023] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0024] figure 2 It is the structure diagram of the damping current controller of the present invention.

[0025] Such as figure 2 As shown, in this embodiment, the damping current controller 100 includes an insulated bobbin 110, a coil 120, a yoke 130, a damping contact assembly 140, a driving assembly 150, a first electrode 160 and a second electrode 170.

[0026] The insulated coil bobbin 110 has a hollow cylindrical shape and can be directly or indirectly fixed on the housing of the damping current controller 100. There are two convex positioning rings on the outer circle of the cylindrical shape, which are an upper positioning ring 111 and a lower positioning ring 112 respectively. The coil 120 is sleeved on the outer circumference of the insulated coil bobbin 110; and is located between the upper positioning ring 111 and the lower positioning ring 112. Th...

Abstract

The invention provides a damping current controller. The damping current controller comprises an insulating coil framework, a coil, a magnet yoke, a damping contact assembly and a driving assembly; the coil sleeves the outer circumference of the insulating coil framework; the magnet yoke sleeves the outside of the coil; a metal damping tube is inserted into an inner hole of the insulating coil framework; one end of the metal damping tube is opened;an iron core moving contact is arranged in the metal damping tube; an iron core static contact is in insulated and sealed connection with the opening of the metal damping tube; a damping spring sleeves the iron core moving contact and is positioned between the iron core moving contact and the iron core static contact; a driving bracket is provided with an ejector rod hole; one end of the driving ejector rod penetrates through the ejector rod hole, is fixedly connected with the iron core static contact and moves linearly along with the movement of the iron core static contact; and the driving spring sleeves the driving ejector rod and is positioned between the driving bracket and the iron core static contact. The controller has the advantages that one controller has two functions at the same time; the control precision is improved, and the anti-vibration characteristic is achieved; and according to different load characteristics, tripping is avoided during short-time passing of overload current.

Description

technical field [0001] The invention relates to a damping current controller. And the application of the damping current controller in the circuit breaker. Background technique [0002] Circuit breakers are the most widely used products in low-voltage electrical appliances. my country has the largest number of manufacturers in this industry, but they all make a living by imitation. Up to now, no circuit breaker has been independently designed in China. More than 90% of enterprises are in middle and low-level repeated production. "Homogeneity" competition is fierce, and mid-range and high-end products are either entirely dependent on imports, or are assembled domestically by foreign-funded enterprises. [0003] At present, the above-mentioned circuit breakers widely used in China can be divided into two types of products for description, one of which is thermal magnetic (bimetal) circuit breaker, which has the advantages of high breaking capacity, complete variety and modu...
