Because the requirement of Modern Family's finishing; Be loaded on circuit breaker or the switch that indoor wall is embedded on the formula magazine and be raised in wall outer height and limited space; The circuit breaker of this structure or switch because the bimetal leaf of overload protection that adopts and short-circuit protection and electromagnetism wink the dynamic formula release volume bigger, be embedded on the formula magazine if be arranged on indoor wall; Because structural configuration limited space; Reason such as adjustment difficulty etc. makes in the market and to realize possessing simultaneously earth leakage protective, overload protection and short-circuit protection function on this series products structure and bring difficulty, and the requirement of causes users slowly is difficult to realization.
Summary of the invention
The objective of the invention is deficiency to prior art; And provide a kind of indoor wall that is loaded on to be embedded on the formula magazine; Can realize possessing simultaneously the function that earth leakage protective, overload protection and short-circuit protection are arranged; And simple in structure, cost is low, volume is less, protrudes from outer height circuit breaker or the switch low, elegant in appearance of wall.
The technical scheme that realizes the object of the invention is:
A kind of circuit breaker or switch; Comprise moving contact, fixed contact, power inleting terminal, load wiring end, action release, leakage protection module, outer cover, pedestal; The pitch-row of said pedestal installing hole is consistent with the pitch-row that wall is embedded into the corresponding installing hole on the formula magazine, and different with prior art is: said pedestal is provided with and moves the lubricating cup formula release that release matches; Coil in the said lubricating cup formula release is connected between moving contact and the load wiring end or is connected between power inleting terminal and the fixed contact.
Armature in the said lubricating cup formula release separates fully with yoke and does not contact; And directly be arranged on the dropout part of action release of circuit breaker or switch; The corresponding setting of yoke pole-face in armature pole-face and the lubricating cup formula release; Armature in the perhaps said lubricating cup formula release contacts with yoke through modes such as the yoke edge of a knife or rotating shafts and connects as one, and can rotate around the edge of a knife or rotating shaft, and armature with move the corresponding setting of dropout part of release.
The pitch-row of the installing hole of said pedestal is 59 ~ 61mm or 70 ~ 72mm.
The present technique scheme do not adopt bimetal leaf and electromagnetism wink the dynamic formula release; But adopt lubricating cup formula release; Realized being loaded on indoor wall and be embedded into circuit breaker or switch on the formula magazine and possess simultaneously earth leakage protective, overload protection and short-circuit protection function are arranged, and simple in structure, with low cost, volume is less, it is low, elegant in appearance to protrude from the outer height of wall.
This circuit breaker or switch are installed on indoor wall and are embedded on the formula magazine, be applicable to need possess simultaneously earth leakage protective is arranged, the electrical equipment of overload protection and short-circuit protection function.
