Accompanying drawing explanation
Fig. 1 is the structural representation of the fusible circuit breaker of a preferred embodiment of the present invention.
Embodiment
Present pre-ferred embodiments is provided, to describe technical scheme of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, fusible circuit breaker of the present invention comprises anode assemblies 1 and a cathode assembly 2, and described anode assemblies 1 comprises brass folder 11 and an aluminum pipe 12, and described cathode assembly 2 comprises brass folder 21 and an aluminum pipe 22 equally.
The brass folder 11 of described anode assemblies 1 presss from both sides 21 with the brass of described cathode assembly 2 and can clamp a fusible link 3 simultaneously, and like this, when normal power-up, described anode assemblies 1 and described cathode assembly 2 just can be electrically connected by described fusible link 3.
Live wire, then for holding cable, particularly, can be positioned in described aluminum pipe 12, and is positioned over by zero line in described aluminum pipe 22 by the aluminum pipe 12 of described anode assemblies 1 and the aluminum pipe 22 of described cathode assembly 2.
In specific embodiment of the invention process, described fusible circuit breaker also comprises an insulation upper cover 4 and and to insulate lower cover 5, described insulation upper cover 4 is for covering all parts of described anode assemblies 1, and described insulation lower cover 5 is then for covering all parts of described cathode assembly 2.Further, the end of described insulation lower cover 5 is stuck in described insulation upper cover 4 just, thus just can surround all parts of described anode assemblies 1 and described cathode assembly 2 by described insulation upper cover 4 and described insulation lower cover 5.
Simultaneously, described fusible circuit breaker also comprises two rubber caps 6, for the aluminum pipe 22 of the aluminum pipe 12 with described cathode assembly 2 that cover described anode assemblies 1 respectively, and described two rubber caps 6 are also tightly connected respectively at described insulation upper cover 4 and described insulation lower cover 5, thus just all parts of described anode assemblies 1 and described cathode assembly 2 are sealed up completely.
And between the end of described insulation lower cover 5 and described insulation upper cover 4, also pad the rubber ring 7 be provided with for sealing.Described rubber ring 7 can to the sealing gap between the end of described insulation lower cover 5 and described insulation upper cover 4, thus make all parts of described fusible circuit breaker all have good sealing property.
