Embodiment
Below in conjunction with Figure of description, the concrete structure of moving contact protective cover of the present utility model is done to illustrate:
A movable contact spring protective cover, as shown in Figures 1 to 5, it comprises the U-shaped cover body 3 being connected and composed with the first connecting plate 2 that is connected two first side plates 1 by two the first side plates 1 that be arranged in parallel, described the first side plate 1 is provided with the first fixing hole 11; Movable contact spring protective cover in the present embodiment also comprises the U-shaped reinforcement 6 being connected and composed with the second connecting plate 5 that is connected two second side plates 4 by two the second side plates 4 that be arranged in parallel; Described U-shaped reinforcement 6 takes shape in described U-shaped cover body 3 inside, and described the second side plate 4 fits with described the first side plate 1, described the second connecting plate 5 fits with described the first connecting plate 2, and described the second side plate 4 is provided with the second fixing hole 41 with described the first fixing hole 11 correspondence positions; In the present embodiment, described U-shaped reinforcement 6 and described U-shaped cover body 3 one compression moldings.When fixing movable contact spring, the holding screw of being located in described the first fixing hole 11 and the second fixing hole 41 is fixed together moving contact protective cover and contact support, and movable contact spring is fixed between described contact support and movable contact spring protective cover; In movable contact spring protective cover of the present utility model, owing to being provided with U-shaped reinforcement 3 on the basis at existing movable contact spring protective cover, therefore can greatly improve the intensity of movable contact spring protective cover, and owing to having set up U-shaped reinforcement 3, movable contact spring protective cover is also difficult for when moulding deforming.
In the present embodiment, described the first connecting plate 2 is provided with spaced for by the separated dividing plate 21 of adjacent movable contact spring, and described dividing plate 21 is parallel to described the first side plate 1 and arranges.The present embodiment utilizes the principle of skin effect, is provided with dividing plate 21 on U-shaped cover body 3, so just adjacent movable contact spring can be separated, and adjacent two movable contact springs are not contacted, and so just can increase the ampacity of movable contact spring.
In the present embodiment, described the first connecting plate 2 has formed away from a side of described the first side plate 1 raised line 22 arranging along described the first side plate 1 bearing of trend that stops electric arc and guide effect, and described raised line 22 is provided with the guide surface 221 of arc or angled straight lines shape.By adopting this structure can prevent that electric arc from damaging circuit breaker inner part, simultaneously because existing of described guide surface 221 (forms the acting surface coordinating with described guide surface 221 on Shell of circuit breaker, in the process that movable contact spring moves to static contact direction, described guide surface 221 staggers with described acting surface effect in case the fixed contact of the moving contact on stop contact and static contact), can make the moving contact on movable contact spring reliably contact with the fixed contact on static contact, there is good result of use.
