Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of integrated thermal overload release support of miniature circuit breaker is provided, and can reduce production costs and the warehousing management cost; Can shorten the production cycle, the consistency of the magnetic property of thermal overload release is fully improved, and can make the circuit breaker machine performance more stable.
The technical scheme that provides according to wooden utility model, the integrated thermal overload release support of miniature circuit breaker comprises connecting plate, leads arc plate, terminal block, feature is: described connecting plate is being led between arc plate and the terminal block, and connecting plate and arc plate or connecting plate and terminal block are made as one.
Described connecting plate is provided with the bearing end that is connected with bimetallic element; Connecting plate is provided with the bearing end that is connected with terminal block; Connecting plate is provided with and leads the bearing end that the arc plate is connected.
Described connecting plate, lead the arc plate and terminal block is formed by the conductive metallic material punching out.
Compared with the prior art the utility model has the following advantages:
The utility model is because with connecting plate with lead arc plate or terminal block and be designed to the incorporate element that formed by the conductive metallic material punching out, the structure of incorporate thermal overload release support element is oversimplified more, reduce the part kind, cost of material and processing cost have not only been saved, also brought convenience for warehousing management, reduced simultaneously and member that it links together between solder joint, shortened the production cycle, also reduced the internal resistance of circuit breaker, and the consistency of the resistance of thermal overload release is improved, thereby make the heat dropout performance of circuit breaker and complete machine performance more reliable and more stable.
