Abstract
The utility model relates to a miniature breaker, which mainly resolves the problem that the double metal release connection rod of the prior miniature breaker is easy to release in the process of use, thereby being bad in product stability and influencing the service life of the prior miniature breaker. The miniature breaker comprises a housing, wherein inside the housing there are provided a double metal sheet, a connection rod and a release mechanism, one end of the connection rod is matched with the double metal sheet, the other end of the connection rod is connected with the release mechanism, the middle portion of the connection rod is provided with a first through hole, a limited post fixedly connected with the housing passes through the first through hole, the connection rod can be slidably arranged at the periphery of the limited post through the first through hole, the end portion of the limited post is provided with a separation blade, and the separation blade is axially matched with the connection rod in a manner of limit. The miniature breaker employs a rivet to replace the pin of the double metal release connection rod, thereby effectively avoiding the release of the double metal release connection rod in the process of use, ensuring product use stability, and effectively increasing product use performance.
Description
Technical field
The utility model relates to a kind of electric circuit protection equipment, refers in particular to a kind of two good miniature circuit breaker of golden trip link serviceability.
Background technology
Miniature circuit breaker is widely used in circuit control appliance field, and for the protection of circuit safety, the two golden trip link of existing miniature circuit breaker is to adopt slide-bar to connect, and in use, trip link is deviate from from slide-bar easily, thereby affects serviceability.
Summary of the invention
For the shortcoming and the weak point that overcome background technology, the utility model provides a kind of miniature circuit breaker.The two golden trip link that solves existing miniature circuit breaker breaks away from use easily, causes the poor stability of product, thereby affects the problem in useful life.
The technical solution of the utility model is: a kind of miniature circuit breaker, comprise housing, be provided with bimetal leaf, connecting rod and tripping mechanism in the described housing, one end of described connecting rod matches with described bimetal leaf, the other end of described connecting rod is connected with tripping mechanism, the middle part of described connecting rod is provided with the first through hole, pass the limited post that is fixedly connected with housing in described the first through hole, described connecting rod can be located at the periphery of limited post slippingly by described the first through hole, and the end of described limited post is provided with catch, and described catch cooperates with the connecting rod axial limiting.
The inboard of described housing is provided with boss, and described boss is provided with blind hole, and described limited post embeds in the described blind hole.
Described limited post is the first rivet.
Described tripping mechanism comprises snap close, and the end of described connecting rod is provided with the second through hole, passes the second rivet that is fixedly connected with snap close in described the second through hole.
The utlity model has following beneficial effect: because two golden trip links adopt the limited post with catch to replace bearing pin, prevented that effectively two golden connecting rods break away from use, guaranteed the stability that product uses, thereby so that serviceability effectively improved.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of another angle of the utility model.
Among the figure, housing 1, bimetal leaf 2, connecting rod 3, the first through holes 4, limited post 5, catch 6, boss 7, snap close 8, the second through holes 9, the second rivets 10.
Embodiment
The below is described further embodiment of the present utility model for accompanying drawing:
Shown in figure, a kind of miniature circuit breaker, comprise housing 1, be provided with bimetal leaf 2, connecting rod 3 and tripping mechanism in the described housing 1, one end of described connecting rod 3 matches with described bimetal leaf 2, the other end of described connecting rod 3 is connected with tripping mechanism, the middle part of described connecting rod 3 is provided with the first through hole 4, pass the limited post 5 that is fixedly connected with housing 1 in described the first through hole 4, described connecting rod 3 can be located at the periphery of limited post 5 slippingly by described the first through hole 4, and the end of described limited post 5 is provided with catch 6, and described catch 6 cooperates with connecting rod 3 axial limitings.According to such scheme because two golden trip links adopt the limited post with catch to replace bearing pin, prevented that effectively two golden connecting rods break away from use, guarantee the stability that product uses, thereby so that serviceability effectively improved.
In the utility model, the inboard of described housing 1 is provided with boss 7, and described boss 7 is provided with blind hole, described limited post 5 embeds in the described blind hole, described limited post 5 adopts the first rivet, and limited post 5 can adopt pin, bolt and screw etc. certainly, selects as required.
In the utility model, described tripping mechanism comprises snap close 8, and the end of described connecting rod 3 is provided with the second through hole 9, passes the second rivet 10 that is fixedly connected with snap close 8 in described the second through hole 9.Connecting rod 3 can be in the 4 interior slips of the first through hole, when being subjected to thermal overload protection, and bimetal leaf 2 heated bendings, connecting rod 3 is pressed on the top, and connecting rod 3 slides and drives snap closes 8 actions so that breaker open operation, thus the safety of protective circuit.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
