The moving contact of breaker assembly; Usually all comprise contact chip, conducting block, outreach and run in and the supporting instrument transformer of using of circuit breaker; Instrument transformer is provided with through hole, and conducting block is located in the through hole, is connected through movable conduction connecting line between contact chip and the conducting block; Outreaching runs in is arranged on conducting block and conducts electricity the connecting line opposite side relatively, and contact chip is provided with the silver alloy contact.For the internal resistance that reduces circuit breaker to reduce the circuit breaker temperature rise, increase usually and outreach the width that runs in to reach this purpose.In the prior art; Conducting block has adopt integral type or split type with running in outward, and non-miniaturization circuit breaker adopts integral type, referring to accompanying drawing 1; Its conducting block is the integrative-structure of long strip type with running in outward, and the through hole internal diameter of instrument transformer must be greater than this long strip type width and height; It is split type that the miniaturization circuit breaker adopts, and referring to accompanying drawing 2 and accompanying drawing 3, but its conducting block needs a configuration bigger transition joint face through screw to be fixedly connected with running in outward, thereby has reduced the economic index of its unfailing performance and circuit breaker.
Summary of the invention
To the deficiency that prior art exists, the purpose of the utility model is to provide a kind of minimizing amount of copper consuming, and product cost is lower, and reliability is higher, the better miniaturization moving contact of breaker of circuit breaker performance index assembly.
For realizing above-mentioned purpose; The utility model provides following technical scheme: a kind of moving contact of breaker assembly, and comprise contact chip, conducting block, outreach and run in and the supporting instrument transformer of using of circuit breaker, instrument transformer is provided with through hole; Conducting block can be located in the through hole; Be connected through movable conduction connecting line between contact chip and the conducting block, outreaching runs in is arranged on the movable relatively conduction connecting line of conducting block opposite side, and contact chip is provided with the silver alloy contact; Said conducting block is the integral type setting with outreaching to run in, and outreaches run in width or height greater than said instrument transformer through hole internal diameter.
The utility model technical scheme during assembling, is passed contact chip with the supporting through hole with instrument transformer of circuit breaker earlier; Be set on the conducting block or will conduct electricity connecting line earlier and pass the supporting through hole of circuit breaker, more movable conduction connecting line is connected with conducting block, because conducting block is the integral type setting with outreaching to run in instrument transformer; Make that cancelled the transition joint face has reduced amount of copper consuming, and reduced product cost, and conducting block and outreach to run in and be the integral type setting; Conducting block does not need to be connected with screw with outreaching to run in again; Increase reliability, reduced internal resistance, and strengthened the circuit breaker performance index.
The utility model further is set to: said outreach to run in be arranged on the opposite side of the corresponding movable conduction connecting line of conducting block.
Through technique scheme, running in outward when making assembling is connected convenient with movable conduction connecting line.
The utility model further is set to: said conducting block and movable conduction connecting line form a fixed connection through methods such as welding.
Through technique scheme, outreaching when further making assembling runs in is connected convenient with the conduction connecting line.
The utility model further is set to: said outreach to run in adopt horizontal or vertical direction setting.
Through adopting technique scheme, to adapt to the different model of circuit breaker.
The utility model further is set to: running in outside said is set to one or more.
Through technique scheme, to adapt to the different model of circuit breaker.
Below in conjunction with accompanying drawing the utility model is further described.
