A kind of plug in circuit breaker with annex connected structure, comprise breaker body and erecting bed, circuit breaker is provided with main circuit plug, erecting bed is provided with main circuit socket, annex connected structure comprises plug-assembly and jack assemblies, plug-assembly and jack assemblies, according to the deployment scenarios of structure, are arranged in circuit breaker side or erecting bed side; If be arranged on circuit breaker side, plug-assembly or jack assemblies are connected with the annex that is contained in circuit breaker inside on electric, and connected mode adopts wire bonds, grafting or screw to fix; If be arranged on erecting bed side, plug-assembly or jack assemblies are connected with the secondary connection end on erecting bed on electric.
Plug-assembly adopts the mode of plug insertion socket to be connected with jack assemblies, and the plug portion in plug-assembly adopts copper cylindrical component, and part outer surface is zinc-plated, silver-plated or gold-plated; Socket part in jack assemblies adopts copper cylindrical component, and part outer surface is zinc-plated, silver-plated or gold-plated.
Plug portion and socket part also can adopt the structure of plane socket and elastic contact pin;
Further, pack elastic component in plug portion into, make plug have certain elasticity, can make plug be pressed on socket with certain pressure, connecting effect will be better;
Plug portion or socket part also can process with having certain flexible tin bronze band or beryllium bronze band, zinc-plated, silver-plated or gold-plated; Be connected with socket part or plug portion in the mode compressing, make can keep good contact and necessary contact after plug portion insertion.
If the plate shaped part that socket part is made with copper material, can be directly with the welding stage of electronic circuit board as socket, or with copper rivet or weld and make in the circuit board socket, the connection of wire is more convenient like this.
Further, in order to make plug reliably insert socket, socket part also comprises a guide frame part, and has certain cooperation requirement, to guarantee that in breaker body and erecting bed insertion or withdrawal process, position is accurate, unlikely damage plug and socket.
Beneficial effect:
1, the connection that the present invention utilizes plug-assembly and jack assemblies to adopt the mode that plug portion is inserted to socket part to realize control circuit substitutes the form of traditional attachments wiring, avoid because wiring error causes annex to damage or functional fault, save maintenance time, greatly reduce maintenance difficulty, solved the fast-wiring problem of circuit breaker accessory simultaneously.
2, the present invention packs elastic component in plug-assembly, makes plug have certain elasticity, can make plug be pressed on socket with certain pressure, has ensured the reliability that plug contacts with socket.
3, the present invention is to set up respectively guide frame part in plug-assembly and jack assemblies, and has certain cooperation requirement, with guarantee that breaker body and erecting bed insert or withdrawal process in position accurate, unlikely damage plug and socket.
