Abstract
The invention discloses a circuit breaker base which is characterized in that the circuit breaker base is provided with a mounting groove for accommodating a power panel. The installation groove for accommodating the power panel is formed, so that the power panel does not need to be assembled in a side-hanging backpack manner as in the prior art, the space is saved, the overall structure of the circuit breaker is simple, the installation cost is saved, and the installation of other accessories of other circuit breakers is more convenient. According to the invention, the screw mounting hole does not need to be embedded with an opening piece in an auxiliary manner when a screw is screwed in, so that the production process is greatly simplified, the damage of the opening piece can be effectively prevented, and the production cost is further saved.
Description
Technical field
the present invention relates to a kind of circuit breaker pedestal.
Background technology
pedestal is the parts of an outbalance of circuit breaker; It normally is used for fixing trigger mechanism, thermal element, electronic building brick and fixed contact; If describe circuit breaker with one tree; Pedestal just is equivalent to the root of big tree so, this shows the importance of pedestal.
existing circuit breaker; Especially be example to mould shell small intelligent circuit breaker (common have 160 types, 250 model), because the restriction of breaker body size, the electronic building brick part all is dimeric; The one, controller part, the 2nd, power panel part.Existing above-mentioned this type circuit breaker all is that controller is built-in, and power panel is external, and the form of hanging knapsack with the side exists, and the shortcoming of bringing like this is following:
1. side hang the overall dimension that knapsack can increase circuit breaker, make that the circuit breaker profile is more too fat to move.
2. side hang the installation that knapsack can influence other annexes on the circuit breaker.
3. side hang production process and the production cost that knapsack has increased circuit breaker undoubtedly.
in addition, the diameter of the screw mounting hole on the existing circuit breaker pedestal all than screw come big, its objective is in installing hole, to be bumped into out part.Yet in the production process of reality; The technological requirement that is bumped into out part is than higher; Open part and must vertically put into installing hole; The angle of putting into has deviation will cause screw to twist not enter slightly, or makes that when assembling opening the part damage causes unnecessary waste, and this has also increased the production cost of circuit breaker undoubtedly to a certain extent.
Summary of the invention
the present invention seeks to: provide a kind of simple for structure, the circuit breaker pedestal that manufacturing cost is lower.
technical scheme of the present invention is: a kind of circuit breaker pedestal is characterized in that having the mounting groove that is used to hold power panel on this circuit breaker pedestal.
are preferred, and mounting groove described in the present invention is positioned at the positive middle part of circuit breaker pedestal.
are further, are provided with some screw mounting holes around the back side of the pedestal of circuit breaker described in the present invention, and the diameter of said screw mounting hole is less than the diameter of mounting screw.
further since at present in the industry known mounting screw diameter be 3.5mm (is example with 160 types, 250 model), so the diameter of screw mounting hole must be less than 3.5mm among the present invention.
are concrete, the preferred 3mm of the diameter of screw mounting hole described in the present invention.
the present invention opens a mounting groove in the front of circuit breaker pedestal, power panel is placed in the mounting groove, stretches out in the trough that power line then can originally just be provided with from the circuit breaker pedestal to be connected on fixed contact and the front end power supply.
the present invention changes the screw mounting hole that script on the circuit breaker pedestal need be bumped into out part into less than the mounting screw diameter screw mounting hole; Concrete fixedly the time; Screw directly screws in the screw mounting hole; Need not to be bumped into out again part, effectively simplified production process, practiced thrift production cost.
Advantage of the present invention is:
1. the present invention owing to have a mounting groove that holds power panel; The form that need not as prior art, power panel to be hung knapsack with side is assembled; Saved the space; Make the circuit breaker terminal with compact integral structure, and saved installation cost, simultaneously the installation of convenient other other annexes of circuit breaker.
2. the present invention are bumped into out part because its screw mounting hole need not to assist when hammering into screw, simplified production process greatly, can prevent out effectively that also part damages, and has further saved production cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is a circuit breaker pedestal dorsal view provided by the invention;
Fig. 2 is the right view of Fig. 1.
wherein: 1, circuit breaker pedestal; 2, mounting groove; 3, screw mounting hole.
Embodiment
embodiment: combine Fig. 1, shown in Figure 2; This circuit breaker pedestal 1 that present embodiment provides; Its positive middle part has the mounting groove 2 that is used to hold power panel; Simultaneously be provided with some screw mounting holes 3 around the back side of said circuit breaker pedestal 1, the diameter of each screw mounting hole 3 is 3mm, all less than the diameter 3.5mm of mounting screw.
A mounting groove 2 is opened in the front of this circuit breaker pedestal 1 that
present embodiment provides; Power panel is placed in the mounting groove 2; Stretch out in the trough that power line then can originally just be provided with from the circuit breaker pedestal 1 and be connected on fixed contact and the front end power supply; Need not as prior art the form that power panel is hung knapsack with side is assembled, saved the space, make the circuit breaker terminal with compact integral structure; And saved installation cost, the installation of convenient other other annexes of circuit breaker simultaneously.
this circuit breaker pedestal 1 simultaneously change the screw mounting hole that script on it need be bumped into out part into less than the mounting screw diameter screw mounting hole 3; Concrete fixedly the time; Screw directly screws in the screw mounting hole 3, need not to be bumped into out part again, has effectively simplified production process; Also can effectively prevent out the damage of part, further practice thrift production cost.
the foregoing description certainly only are explanation technical conceive of the present invention and characteristics, and its purpose is to let the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All modifications that the spirit of main technical schemes is done according to the present invention all should be encompassed within protection scope of the present invention.
