Specific embodiment
Below in conjunction with the embodiment that attached drawing 1 to 6 provides, the specific reality of the breaker assembly of the invention is further illustrated
Apply mode.The breaker assembly of the invention is not limited to the following description.
As shown in Figure 1-3, the breaker assembly of the invention includes assembled axis 1 and two breaker units 5, it is each described
Breaker unit 5 is equipped with the assembled hole 20 connecting with the assembled realization of axis 1 shaft hole matching, described two breaker units 5
Between assembled connection side by side realized by the assembled axis 1, the both ends of the assembly axis 1, which are respectively provided with, extends to the spelling
The flattening portion 11 inside hole 20 is filled, the periphery in the flattening portion 11 includes recessed in the flattening on the outer wall 15 of the assembled axis 1
Recess 12 and the flattening protrusion 14 being convexly equipped on the outer wall 15 of the assembled axis 1.Assembled axis 11 can not only be recessed by flattening
While the contact area reduction assembly difficulty in when sunken 12 reduction assembly and assembled hole 20, and passes through and flatten raised 14 and assembly
Hole 20 forms closer cooperation.In addition, the invention is not limited in two breaker units 5 when being bolted together, example
If the pole 3P breaker assembly is that three breaker units are bolted together use, assembled axis 1 is connected to two adjacent breakers
Between unit 5, similarly 3P+N breaker assembly can also be connected by assembled axis 1, belong to the protection model of the invention
It encloses.Further, the flattening recess 12 and flattening protrusion 14 in each flattening portion 11 are respectively equipped at least two, each flattening
The flattening recess 12 in portion 11 and the flattening protrusion 14 are in interlaced arrangement in the outer radial periphery of the assembled axis 1.In addition,
Also multiple flattening recess 12 being arranged alternately can be set in one flattening portion 11 and flatten protrusion 14, can equally reduce dress
The difficulty matched and the reliability for improving connection, but the difficulty and cost of processing and fabricating can be improved.
Further, the flattening recess 12 and flattening protrusion 14 in each flattening portion 11 are respectively equipped with two, each flattening
The recess 12 of flattening of two of portion 11 is symmetrical set in the outer radial periphery of the assembled axis 1, each flattening portion 11
Two protrusions 14 of flattening are symmetrical set in the outer radial periphery of the assembled axis 1.By the way that two 11 energy of flattening portion are arranged
Enough on the basis of improving assembly efficiency and connection reliability, guarantee the assembled structural strength of axis 11 and the cost of production.
Further, the both ends for flattening recess 12 on the axial direction of the assembled axis 1 respectively with the assembled axis 1
Outer wall 15 between form overhead kick step 13, assembled hole 20 and assembled axis 11 are both preferably circle, and assembled axis 1 and assembled hole
20 interference fits.Closer cooperation can be formed with assembled hole 20 by flattening protrusion 14 and overhead kick step 13, make assembled axis 1
It can more reliably be connect with lock 2.
A kind of embodiment of breaker unit 5 as shown in Figure 2, breaker unit 5 include being arranged in the intracorporal operation of shell
Mechanism 4, the handle 41 connecting respectively with operating mechanism 4 and moving contact 42, the static contact being oppositely arranged with moving contact 42 are (in figure
It is not shown), and the tripping protection mechanism (not shown) cooperated with operating mechanism 4, when breaker unit 5 is spliced together
Handle 41 can be linked together, when rotational handle 41 can drive the operating mechanism 4 of each breaker unit 5 respectively, pass through
Operating mechanism 4 drives moving contact 42 and static contact stationary contact and separates, but since breaker unit 5 is respectively connected to different phases
In line, if a certain phase line failure, the tripping protection mechanism for accessing the breaker unit 5 of the phase line can unlock operating mechanism 4,
Released by the energy storing members of operating mechanism 4 moving contact 42 and static contact can be driven to separate (energy storing members connect in moving contact 42 with static contact
The process meeting energy storage of touching), while disconnecting the phase line of failure, other breaker units 5 are driven by the assembled axis 1
