Description

A kind of circuit breaker or switch

Technical field

The present invention relates to circuit breaker or switch, relate in particular to and be loaded on indoor wall and be embedded on the formula magazine circuit breaker or switch with earth leakage protective, overload protection and short-circuit protection.

Background technology

Development along with science and technology; increasing of home appliance; the user is in the urgent need to more fully protecting power consumption equipment being loaded on circuit breaker or the switch that indoor wall is embedded on the formula magazine: not only have earth leakage protective, also should possess overload protection and short-circuit protection function simultaneously.

The existing indoor wall that is loaded on is embedded into circuit breaker or switch on the formula magazine, such as CN2781543 disclosed a kind of " switch on wall ", its structure is: " comprise lid, pedestal and be fitted to actuating mechanism on the pedestal; contact system and wiring system; described actuating mechanism is made of handle and connecting rod actuating mechanism, handle is loaded on the pedestal by the arm pivot post hinge; Described contact system is the single-break clapper-type contact system that is made of moving contact and fixed contact; The defencive function assembly also is installed on the pedestal; Described defencive function assembly is the creepage protection function assembly; Or electric leakage adds the overload protection function assembly; Or electric leakage adds the short-circuit protection function assembly; Or electric leakage adds overload and adds the short-circuit protection function assembly; ".The disclosed creepage protection function assembly of this patent is: consist of tripping system by circuit board and coil and dropout actuating mechanism and form; The overload protection function assembly is: be fixed in the bimetal leaf that the other end is against on the connecting rod actuating mechanism on the fixed head by an end and consist of; The short-circuit protection function assembly is: the electromagnetism wink dynamic formula release that is comprised of iron core, coil, reaction spring.

Because the requirement of Modern Family's finishing; be loaded on that indoor wall is embedded into circuit breaker on the formula magazine or switch is raised in wall outer height and limited space; the circuit breaker of this structure or switch; because the overload protection that adopts and the bimetal leaf of short-circuit protection and electromagnetism wink the dynamic formula release volume larger; if being arranged on indoor wall is embedded on the formula magazine; because structural configuration limited space; adjust the reasons such as difficulty; make in the market and can realize possessing simultaneously earth leakage protective on this product structure; overload protection and short-circuit protection function bring difficulty, cause user's requirement slowly to be difficult to realize.

Summary of the invention

The objective of the invention is for the deficiencies in the 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, small volume, 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 described pedestal installing hole is consistent with the pitch-row that wall is embedded into the corresponding installing hole on the formula magazine, unlike the prior art be: described pedestal is provided with and moves the oil-cup type release that release matches; Coil in the described oil-cup type 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 described oil-cup type 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 oil-cup type release, perhaps the armature in the described oil-cup type release contacts with yoke by 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 described pedestal is 59 ~ 61mm or 70 ~ 72mm.

The technical program do not adopt bimetal leaf and electromagnetism wink the dynamic formula release; but adopt the oil-cup type release; realized being loaded on indoor wall and be embedded into circuit breaker on the formula magazine or switch and possess simultaneously earth leakage protective, overload protection and short-circuit protection function are arranged, and simple in structure, with low cost, small volume, to protrude from the outer height of wall low, elegant in appearance.

This circuit breaker or switch are installed on indoor wall and are embedded on the formula magazine, be applicable to possess simultaneously earth leakage protective is arranged, the electrical equipment of overload protection and short-circuit protection function.

Embodiment

Below in conjunction with drawings and Examples content of the present invention is further elaborated, but is not limitation of the invention.

Embodiment 1:

With reference to Fig. 1, a kind of circuit breaker or switch, comprise pedestal 1, outer cover, power inleting terminal, fixed contact 8, moving contact 7, load wiring end 15, action release 11, leakage protection module 13 and arc-extinguish chamber 10, be installed with action release 11 on the pedestal 1, electric leakage tripping coil 9, leakage protection module 13, power inleting terminal, fixed contact 8, moving contact 7, load wiring end 15 and arc-extinguish chamber 10, pedestal 1 is provided with the consistent pedestal installing hole 12 of pitch-row that pitch-row and indoor wall are embedded into the corresponding installing hole on the formula magazine, also is provided with on the pedestal 1 and moves the oil-cup type release that release 11 matches; Oil-cup type trip coil 2 is connected between moving contact 7 and the load wiring end 15 or is connected between power inleting terminal and the fixed contact 8.

Particularly; the oil-cup type release comprises oil-cup type tripping coil 2; yoke 3; lubricating cup 4; armature 5; one end of oil-cup type trip coil 2 is connected with moving contact 7 by soft connection; the instrument transformer that the other end passes in the leakage protection module 13 by soft connection 14 is connected with load wiring end 15; power inleting terminal when having realized switch closure; fixed contact 8; moving contact 7; oil-cup type trip coil 2 and load wiring end 15 are cascaded; perhaps an end of oil-cup type trip coil 2 is connected with power inleting terminal by soft connection; the other end is connected with fixed contact 8 by soft connection, power inleting terminal when having realized switch closure; fixed contact 8; oil-cup type trip coil 2; moving contact 7 and load wiring end 15 are cascaded.

The oil-cup type release is arranged on a side of leakage protection module 13.

The armature 5 of oil-cup type release is arranged on the dropout part 6 of action release 11 of circuit breaker or switch, the oil-cup type release that this example adopts is different from the structure of the cup type release of traditional oils, difference is: the armature 5 in the oil-cup type release separates fully with yoke 3 and does not contact, and armature 5 is arranged on the dropout part 6 of circuit breaker or switch, armature 5 pole-faces and the corresponding setting of yoke 3 pole-faces.
