Abstract
The utility model relates to a connecting system for an electric leakage circuit breaker, comprising a base seat providing with a flashboard inside, a flexible connection, a static contact, a movable contact, a positioning element, a contact compression spring, a rotating shaft, a rotating shaft compression spring and a residual current transformer. The left and the right edges of the side normally outputting lines of the base seat are provided with insert slots of the flashboard. A line input flashboard is inserted into the insert slot on the left side of the base seat. The line input flashboard is connected with the static contact by the flexible connection. The static contact is arranged at the side of normally inputting lines of the base seat. The movable contact is positioned in the rotating shaft by the positioning element. The movable contact is connected with the static contact by the rotating shaft which rotates by being driven by an operating mechanism. The movable contact passes the residual current transformer and is connected with a line output flashboard by the flexible connection. The line output flashboard is inserted into the insert slot on the right side of the base seat. Because the connecting system of the electric leakage circuit breaker adopting the structure uses flashboards for inputting and outputting the lines in the same direction, the connecting system for an electric leakage circuit breaker is very convenient to connect the lines in a power distribution box and saves the spacing of connecting the lines in the power distribution box.
Description
Technical field
The utility model relates to the heavy-current control field, and particularly leakage, breaking protective device field specifically is meant a kind of wiring system of residual current circuit breaker.
Background technology
In the prior art, the small-sized residual current circuit breaker mode of connection is all upper end, normal mounting position inlet wire, lower end outlet.But when in a kind of novel distribution box system, using, such residual current circuit breaker wiring inconvenience and comparatively loaded down with trivial details.
The utility model content
The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, and a kind of simple in structure, a kind of small-sized residual current circuit breaker of using easy-to-connect is provided.
In order to realize above-mentioned purpose, the wiring system of residual current circuit breaker of the present utility model has following formation:
The wiring system of this residual current circuit breaker, comprise pedestal, in establish plate, be flexible coupling, fixed contact, moving contact, keeper, contact compression spring, rotating shaft, rotating shaft compression spring, residual current transformer, described contact compression spring is positioned between the cylinder shape groove at the cylindrical boss at described keeper middle part and described moving contact rear portion, described rotating shaft compression spring is positioned between the cylindrical boss and the cylindrical end tangs in the deep-slotted chip breaker of rotating shaft middle part of inclined to one side front position, described pedestal middle part, it is characterized in that, the normal outlet one side the right and left of described pedestal is respectively established a plate slot, an inlet wire plate inserts in the slot on the pedestal left side, and this inlet wire plate is connected with fixed contact by being flexible coupling, described fixed contact is in normal inlet wire one side of pedestal, moving contact is positioned in the rotating shaft by keeper, described moving contact is connected with fixed contact by the rotation of the rotating shaft that operating mechanism drives, and this moving contact passes residual current transformer and is connected with an outlet plate by being flexible coupling, and this outlet plate inserts in the slot on pedestal the right.
Since adopted the wiring system of the residual current circuit breaker of this utility model, because the turnover line has all used plate, and in same direction, the wiring that makes it in distribution box is very convenient, and saved wiring space in distribution box, it is simple and reliable for structure that it is had, advantage easy to use.
Description of drawings
Fig. 1 is an internal structure schematic diagram of the present utility model.
Fig. 2 is a dextrad partial sectional view of the present utility model.
Embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also illustrated in figures 1 and 2, the wiring system of this residual current circuit breaker, comprise pedestal 1, in establish plate, be flexible coupling 3 and 11, fixed contact 4, moving contact 8, keeper 6, contact compression spring 7, rotating shaft 5, rotating shaft compression spring 10, residual current transformer 12, wherein, pedestal 1 normal outlet one side the right and left is respectively established one of plate slot, plate 2 inserts pedestal left side slot as inlet wire plate 2, inlet wire plate 2 usefulness are flexible coupling and 3 are connected with fixed contact 4, fixed contact 4 is in pedestal 1 normal inlet wire one side, moving contact 8 is positioned in the rotating shaft 5 by keeper 6, being connected of moving contact 8 and fixed contact 4 finished in the rotation that drives rotating shafts 5 by operating mechanism 14, moving contact 8 usefulness are flexible coupling and 11 pass residual current transformer 12 and be connected with outlet plate 13, and outlet plate 13 inserts in pedestals 1 the right groove.Inlet wire plate 2 and outlet plate 13 all adopt plug-in type to connect all in entopic outlet one side on both sides, pedestal 1 bottom.
When reality is used, one of slot is respectively established on leading-out terminal (being the lower end) both sides in pedestal 1 normal mounting position, the slot in the left side inserts plate as the live wire end of incoming cables, the slot in the right inserts plate as the live wire leading-out terminal, inlet wire plate 2 and outlet plate 13 point-blank so that the plug in type connection in the distribution box.In the middle of pedestal 1 lower end one on the right of the upper end one as zero line into and out of the line binding post.Inlet wire plate 23 is connected to fixed contact 4 by being flexible coupling.Be flexible coupling 3 with the connected mode of inlet wire plate 2 and fixed contact 4 be the spot welding mode.Moving contact 8 is fixed in the keeper 6, provide the contact pressure support by contact compression spring 7, be fixed in the rotating shaft 5 then together, being connected of moving contact 8 and fixed contact 4 finished in the rotation that drives rotating shafts 5 by operating mechanism 14, in breaking course, provide counter-force by rotating shaft compression spring 10, make it quick disjunction, contact on the fixed contact 4 is located on the relative position with contact on the moving contact 8, its the place ahead is provided with arc-control device 9, in order to extinguish arcs in breaking course, moving contact 8 usefulness are flexible coupling and 11 pass residual current transformer 12 and be connected with outlet plate 13, be flexible coupling and 11 adopt the spot welding modes to be connected with moving contact 8 and outlet plate 13, outlet plate 13 inserts in pedestals 1 the right groove.
The utility model also is provided with the chamfering of a R type in the bottom of plate, so that insert, also be provided with spherical boss in the plate bottom in addition, with the reliability that guarantees to peg graft.
