The utility model has the beneficial effects that opening up plugboard trough on middle cover, small wiring board is inserted in plugboard trough across middle cover
Be electrically connected with the conductive sheet on the connecting terminal in breaker unit, realize it is internal take electricity to attach most importance to switching-on mechanism power supply, it is this to take
Electric mode takes full advantage of the space inside miniature circuit breaker, and electricity getting device need not additionally be arranged, and does not have to increase volume, and
It is easy to connect.
The utility model is further arranged to the conductive sheet and includes the fixed part being connect with terminal plate and be oppositely arranged
The inwardly protruded elastic portion in fixed part both sides, small wiring board realize connection between being inserted in conductive sheet elastic portion.Above-mentioned setting is led
Electric piece clamps small wiring board using the elastic portion being oppositely arranged and realizes conduction, more reliable and more stable.
The utility model is further arranged to form guide groove on the upper and lower two side in the plugboard trough, guide groove with
Gap between two elastic portions is corresponding.Small wiring board be inserted into when can limit in guide groove, not only make it is easy for installation, and
And stable connection.
The utility model is further arranged to be connected with motor wiring board and contact pin female seat on the main circuit board, motor electricity
Road plate is connected to motor end, and motor wiring board is corresponded on main circuit board and forms slot, motor wiring board is inserted in slot and master
Wiring board connects, and contact pin female seat corresponds to plugboard trough setting, is provided with contact pin on the small wiring board, contact pin is corresponding with contact pin female seat
Connection.Connection by socket and contact pin female seat is more convenient, and motor wiring board is connected also by slot, convenient for assembly.
