It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The following description will further explain embodiments of the present invention with reference to the drawings.

As shown in fig. 1-3, an integrated circuit breaker splicing copper bar comprises a zero line copper bar 1 and a fire line copper bar 2, wherein the zero line copper bar 1 and the fire line copper bar 2 are arranged in parallel and are spaced from each other, the zero line copper bar 1 and the fire line copper bar 2 both comprise copper bar bodies, each copper bar body comprises a fixed seat 3 and a splicing part 4, each splicing part 4 is uniformly and fixedly connected to one side of the fixed seat 3 and comprises a connecting body 5 connected with the fixed seat 3, the top end of each connecting body 5 is provided with a splicing head 6 in a connecting manner, and the corresponding splicing heads 6 on the zero line copper bar 1 and the fire line copper bar 2 are arranged in parallel to each other to form a splicing position; the plugging position at least comprises a protective plugging end 7, a bus input end 8 and a branching output end 9 which are arranged in sequence.

As shown in fig. 1-2, when in use, the copper bar is fixedly arranged in the base of the power distribution unit of the circuit breaker, and then various power distribution modules can be inserted on the copper bar through the plug connectors 6 to form a parallel structure, so that a large amount of external wiring can be saved. Wherein protection grafting end 7 can be used for pegging graft surge protector, and bus input 8 generally need occupy two grafting positions at least, and two connector 6 of one of them grafting position all are connected with live wire copper bar 2, and two connector 6 of another grafting position all are connected with zero line copper bar 1, are used for the input of grafting live wire and zero line respectively, and defeated department end of separated time is used for each branch switch of pegging graft.

As shown in fig. 1 and 2, the connecting bodies 5 of the zero line copper bar 1 and the fire line copper bar 2 are arranged close to each other, so that the zero line copper bar 1 and the fire line copper bar 2 form a back-to-back L-shaped structure; the bayonet joint 6 still includes adapter 10, adapter 10 is L shape, one end and 5 fixed connection of connector, the other end is buckled and is connected with insertion piece 11 to between zero line copper bar 1 and the live wire copper bar 2, the vertical setting of insertion piece 11 is between zero line copper bar 1 and live wire copper bar 2, be parallel to each other between all insertion pieces 11, this kind of structure makes all insertion pieces 11 position size homogeneous phase the same, the structure is more general, avoid the module to need to set up different spliced eyes for the position that adapts to bayonet joint 6.

As shown in fig. 3, the plug 6 is a sheet structure, the top of the plug away from the fixing base 3 is a trapezoid with a narrow top and a wide bottom, one side of the lower part of the trapezoid plug 11 is provided with a first clamping portion 12 which is recessed inwards, and the other side is provided with a second clamping portion 13 which protrudes outwards; first joint portion 12 is including setting up at the inside sunken step portion of trapezoidal plug-in strip 11 downside, and second joint portion 13 includes that the top is circular-arc cuboid shape arch, and second joint portion 13 sets up two at least. This structure can make things convenient for the grafting of distribution module, and first joint portion 12 and the cooperation of second joint portion 13 make the distribution module insert the back and be in locking state, prevent to deviate from. Circular-arc can conveniently be dismantled, and under the general condition, because first joint portion 12 only has a limiting displacement, can preferentially demolish first joint portion 12 during the dismantlement, increase the installation convenience.

In the above embodiment, the insulating layer is arranged on the side, close to the lower part of the insertion piece 11, of the zero line copper bar 1 and the fire wire copper bar 2, and the insulating layer can prevent the instant high voltage generated during power-on from striking fire to cause safety accidents. Generally need not set up the insulating layer on the inserted sheet 11, influence transmission of electricity efficiency on the one hand, on the other hand is that the copper bar just can the circular telegram after the module grafting of circular telegram generally, and inserted sheet 11 is located the spliced eye this moment, is in complete isolated state each other, does not have the risk of striking sparks.

In the above embodiment, the positioning grooves 14 are uniformly formed on the outer side of the fixing base 3. Constant head tank 14 generally is triangle-shaped, and triangle-shaped cardboard and the clamp plate that can cooperate to fix in the distribution unit base fix fixing base 3 in the base, also can adopt bolt lug connection to fix on the base, but because the material of copper is generally softer, adopt the bolt atress when dismantling repeatedly to return and lead to the screw hole to warp, make the copper bar position change, consequently adopt the mode of cardboard and clamp plate more fixed.
