Embodiment 1

[0043] This embodiment is a moving contact quick-closing mechanism, combined with figure 1 , figure 2 and image 3 , the moving contact quick-closing mechanism acts on the moving contact 31 and controls the position of the moving contact 31, so that the moving contact 31 is relative to a fixed static contact (the moving contact quick-closing mechanism is not included, not shown in the figure out, see Figure 13 The shown embodiment of the circuit breaker using the moving contact quick-closing mechanism (the component marked 54) moves and switches between two stable positions, and the two stable positions are respectively that the moving contact 31 is in contact with the static contact so that The closed position where the circuit is turned on and the open position where the moving contact moves away from the static contact to open the circuit.

[0044] recombine figure 1 and figure 2 As shown, the moving contact quick-closing mechanism of this embodiment includes a brac...

Embodiment 2

[0062] to combine Figure 13 , this embodiment discloses a circuit breaker, including a housing 50 made of insulating plastic, the housing 50 is composed of two half-shell structures fastened and fixed; the housing 50 is sequentially installed with a first terminal 51 , the magnetic assembly 53, the static contact 54, the moving contact quick-closing mechanism of Embodiment 1, and the second terminal 52; the first terminal 51, the magnetic assembly 53 and the static contact 54 are electrically connected in series in sequence, and at the same time the first terminal 51 is electrically connected in series. The second terminal 52 is electrically connected to the free end of the moving contact 31 of the moving contact quick-closing mechanism through conductive copper sheets and flexible connecting copper wires to form a controllable wiring group.

[0063] The bracket of the quick closing mechanism of the moving contact 31 is fixed in the housing 50 , and the operating member is pr...

Abstract

The invention relates to a moving contact fast-operate mechanism and circuit breaker with the same. An energy storage rod and a stop piece are arranged on a support, an energy storage elastic piece is arranged between the energy storage rod and a moving contact, and the stop piece can abut against and limit the moving contact; meanwhile, the operating piece is connected to the energy storage rod, and is provided with a stir part to stir the stop piece; the operating piece can act on the moving contact through the energy storage rod, so that the purpose of integrating an energy storage mechanism and a moving contact linked mechanism is achieved, the structure of the moving contact fast-operate mechanism is simplified, and the assembly efficiency and the performance stability are improved; the purpose of integrating the energy storage mechanism and the moving contact linked mechanism is achieved, the energy storage elastic piece achieves the effect of dynamically compensating using loss of the moving contact, and the operating piece directly acts on the stop piece. According to the moving contact fast-operate mechanism and circuit breaker with the same, the structure is simpler, and stop and release of the moving contact is stabler and more reliable.

Description

technical field [0001] The present invention relates to the general technical field of circuit equipment, more specifically, the present invention relates to a kind of control line or switch, a kind of moving contact quick-closing mechanism that makes the circuit close quickly and a circuit breaker equipped with the moving contact quick-closing mechanism device. Background technique [0002] A circuit switch or a circuit breaker includes two terminals for connecting lines, and a disconnectable circuit is arranged between the two terminals; the disconnectable circuit includes a moving contact, a static contact, and a switch for controlling the position of the moving contact The operating part, the circuit breaker also includes a locking assembly, a bimetal sheet for controlling the thermal disconnection of the locking assembly, and an electromagnetic disconnecting part containing a coil; the coil of the electromagnetic disconnecting part has a connection with the push rod Th...
