Description

Cassette divides electronic box

The utility model relates to for distribution, specifically is a kind of distribution box.

Distribution box also claims to divide electronic box or switch-box.In the past, because other power consumption of each household is little and electrical equipment is more single, so general only the need gets final product with a master switch formula distribution box.Along with improving constantly of economic development and quality of life, big multi-user's electric equipment is all constantly changing and is increasing, make power consumption increase suddenly, this just needs various big capacity correspondingly, high safety is divided electronic box, and divides electronic box also really to become the important equipment of large and small building now.Combine existing various minute electronic box, general all be casing with welding or establish bore mode and directly lay fixed on the reservation template die in the building wall, and each shunt circuitbreaker installation is fixedly arranged between confluence copper bar positioning seat and stator on the branch electronic box base plate in the solid mode of spiral shell.In theory, electronic box freezed by screw locking and weldering and connect this type of minute, can guarantee durability and the fail safe used, but in fact,, add the problem of construction aspect owing to the error of prefabricated default part, make the branch electronic box after installing have many flaws, for example, make appearance, profile impaired, even cause chamber door to tilt and influence switch; Be more because of electric elements all fixing, make and install and maintenance is quite wasted time and energy that careless slightlyly lock screw not tight, spark phenomenon very easily takes place in the joint with screw; Again just like, because the confluence copper bar positioning seat structure of its use of disposing, all be to make with the one jetting formation process, its specification, length all are again fixing, this just makes that production efficiency is lower, and manufacturing cost is higher, and when installing if find to have length not enough or when the part of damage is arranged, can only be forced to once all change, very uneconomical; And because the setting of its confluence copper bar is all separated by a thin insulating trip again, the security appliance performance is also bad.

The purpose of this utility model provides a kind of cassette that is suitable for family electricity consumption in various minutes and divides electronic box, makes it can do appropriateness adjustment according to condition and specific requirement on the spot when mounted, and makes that its installation, maintenance construction is simple and easy, convenient.

The utility model is the improvement that divides electronic box to existing, so also consist predominantly of casing, chamber door and box plate, confluence copper bar and circuit breaker is housed on the box plate.The utility model can be made the suitably purpose of adjustment to casing and box plate according to the erecting bed condition for realizing, the design disposes Telescopic Fixed respectively on the upper and lower edge fixed position of casing one side; On the corner location of box plate, respectively be preset with curved fixing hole.Simultaneously, for making the utility model reach simple and easy, the purpose easily of installation, maintenance, and making it to have security appliance performance preferably, the design respectively is provided with a row in the upper and lower of box plate can be by two cramp devices for directly fixing the fixedly snap-in elasticity Button Block of circuit breaker fast; Be designed to segmentation cassette structure using the holder pedestal that sets up confluence copper bar, promptly before each unit pedestal of forming confluence copper bar overall fixed seat pedestal, one of back both sides side is provided with and is the jack that the triangle fixed point is arranged, in addition side is provided with corresponding three latches of this three jack on the opposite face with adjacent pedestal, and the upper limb middle position at this pedestal is preset with for the groove of inserting first confluence copper bar, and the both sides upper edge portion improved and constitute and use for setting up the flange of second confluence copper bar, also be respectively equipped with jack in order to the latch of intercalation pedestal cover plate at the upper limb corner location of this pedestal.Like this confluence copper bar unit pedestal of structure, the latch of adjacent two unit pedestals and jack to slotting be connected afterwards a whole pedestal, then make the length of confluence copper bar to adjust according to needs on the spot.After inlay card has set up bus-bar on this whole pedestal that connects into, plant each unit pedestal cover plate into the upper limb of unit pedestal again.

The utility model has the advantages that: the forward and backward position of casing and the angle position that the box plate of electric elements is housed can adjust, even then there is error Yu She installation site, also can successfully install well-behaved electronic box; The card insert type structure is adopted in the connection of electric elements and pedestal thereof, make to install and maintenance work becomes simple and make things convenient for, and can save time, laborsaving, raise the efficiency and the reduction expense is paid.
