Utility model content
The technical problems to be solved in the utility model is: manufacture difficult and that error is larger problem in order to the contact supporting solving circuit breaker in prior art exists, now provide a kind of manufacture simple, can ensure the accurate link span of stitching position and circuit breaker thereof.
The utility model solves the technical scheme that its technical problem adopts: a kind of link span, and comprise two side plates and connect the base plate of two side plates, leave space between two described side plates, the outside of described side plate all has the post that is located by connecting.
In order to overcome the manufacture difficulty and error that punch forming brings, further, described link span is the integral structure of die cast.
Further, the described post that is located by connecting comprises interference portion and guide part, the two ends in described interference portion are fixedly connected with described side plate and guide part respectively, guide part plays the effect of guiding, interference portion and hole interference fit joined together play fixing effect, comparatively easy and convenient when be located by connecting post and hole joined together are spliced, and connect firm.
Preferably, described interference portion is cylindrical, and conically, the large end of described guide part is connected with described interference portion described guide part.
In order to increase bonding strength between link span and fastness, further, the outside of described side plate all has secondary reference column.
Preferably, the cross section of described secondary reference column is Long Circle.
Preferably, described side plate all has pin shaft hole, the pin shaft hole concentric on two described side plates.
Preferably, the post that is located by connecting described in has three and distribution triangular in shape.
The utility model proposes a kind of circuit breaker, comprise at least two above-mentioned link spans and some connectors, the both sides of described connector all offer the connecting hole matched with the described post that is located by connecting, multiple described link span is arranged side by side, be fixedly connected with by described connector between adjacent two link spans, the post correspondence that is located by connecting on described link span is plugged in the connecting hole of described connector, described interference portion and described connecting hole interference fit.
Further, the both sides of described connector all offer the location hole matched with secondary reference column, and the secondary reference column correspondence of described link span is plugged in the location hole of described connector.
The beneficial effects of the utility model are: link span of the present utility model and circuit breaker thereof adopt link span die casting integrated formed structure to solve manufacture difficulty that traditional punch forming brings and error, the post that is located by connecting on link span adopts front end to be guide part rear end is the structure in interference portion, when link span and connector clamping, comparatively easily and connect reliable, adopt the circuit breaker of this kind of link span to be specially what circuit breaker and just select several link span, comparatively simple and convenient and cost is lower.
