Background technology
Circuit-breaker not only has by the operating grip that is provided with in this circuit-breaker is operated, thereby with the function of circuit on/off, be switching function, also have in order to prevent in advance because overcurrent flows through electric wire or load equipment are burnt and the important function that circuitry cuts is such.Disconnection for this circuit, for example in JIS (Japanese Industrial Standards) C8370, defined the such scope of 1kA~200kA as " specified cut-out electric current ", as everyone knows, each manufacturer all is being devoted to enrich product line, with can be corresponding to the situation of this circuit, promptly and the thickness of the distance between the transformer, electric wire etc., suitably select to have the circuit-breaker of suitable specified cut-out electric current.
But when cutting off, produce electric arc between a so-called docking point that constitutes by travelling contact and fixed contact, in order to eliminate this electric arc fast, the preferred arc voltage that is used for pilot arc itself that improves, if for example 2 group of one docking point (so-called one pole double break) therefore is set, then arc voltage correspondingly becomes twice, is specially adapted to the product of high rupturing capacity naturally.The known following structure of object lesson as this one pole double break, center of rotation with respect to the travelling contact seat that can rotate is disposed at point symmetry position with mains side and load-side contact seat, wherein, this travelling contact seat has two travelling contacts at two ends, this mains side and load-side contact seat have the fixed contact paired with each travelling contact (for example, with reference to patent documentation 1) respectively.
Patent documentation 1: the spy opens flat 10-223115 communique (~the 3 page of left hurdle of the 45th row, the 2nd page of right hurdle the 1st row, Fig. 1)
Summary of the invention
As this one pole double break (below, be also referred to as spinning movement (roto-active) formula) structural feature, according to Fig. 1 of patent documentation 1 as can be known, since when cutting off to load-side (right side on the paper) exhaust, so need make mains side travelling contact (label 3) to the housing bottom surface away from direction disconnect.On the other hand, usually, in circuit-breaker,, compare, on contact contact direction, need bigger power with the contact detaching direction in order to ensure the contact reliability between contact.Here, the configuration of the main spring that space availability ratio is the highest be this Fig. 1 direction (promptly, vertical direction), and, according to the structure that constitutes toggle link by last connecting rod and lower link (roughly in line, when not shown disconnection, being roughly " ㄑ " font when the illustrated connection), when driving lower link in switching mechanism portion, less relatively from the power (so-called clockwise disconnection direction) of bottom surface pull-up, but can produce bigger pushing force (so-called counterclockwise connection direction) to the bottom surface direction.
Therefore, considering that this configuration and structure have the advantage that product can obtain high reliability under the situation of the exhaust of described load-side and contact contact pressure.On the other hand, because drive the point of travelling contact seat (hereinafter referred to as rotating part) by lower link, compare with the rotating shaft of this rotating part and to be positioned at mains side (left side on the paper), therefore the switching mechanism portion that comprises lower link also naturally can be near the mains side of this circuit-breaker, and operating grip is configured in mains side similarly.
The ifs circuit circuit breaker all is this spinning movement formula, and then this " near mains side " also is out of question.But, as previously mentioned, specified rupturing capacity has multiple, actual conditions are that each manufacturer must produce with the corresponding manufacturing cost of rupturing capacity specified with it, promptly, the specified rupturing capacity of circuit-breaker is low more, therefore must produce with low more manufacturing cost, not all circuit-breaker all adopts the one pole double break, also have a lot of products adopt the cost performance excellences, so-called one pole list is disconnected.
Yet, also to improve the cut-out performance certainly even this one pole list is disconnected, as its measure, for example make movable contact long as far as possible, to guarantee the separating distance between contact.For this reason, in any case keep the cross bar of movable contact also must to accompany therewith near load-side, the switching mechanism portion that comprises operating grip also is configured in the substantial middle of this circuit-breaker.
Its result, disconnected for one pole double break and one pole list, though the so-called switching mechanism portion from operating grip to lower link can be general, but certainly exist each relevant auxiliary equipment of operating grip and must have two kinds of such troubles, also there is the difference in the appearance design that the position difference as operating grip causes the problem that user's usability aspect is relatively poor.In addition, have special-purpose separately switching mechanism portion if make the position consistency of operating grip, then variation correspondingly on the part standard this point will inevitably lose cost competitiveness.
The present invention proposes in order to solve above-mentioned problem, and its purpose is to obtain in the part standard that realizes switching mechanism portion, also makes its operating grip position obtain unified one pole double break and the disconnected circuit-breaker of one pole list.
