Abstract
The utility model belongs to the field of electrical appliances and relates to a circuit breaker, in particular to a rectangular hollow circuit breaker porcelain knob. The rectangular hollow circuit breaker porcelain knob comprises a porcelain knob body, wherein the porcelain knob body is in a porcelain structure with a hollow part in the middle part; and an opening at the lower end of the hollow part is arranged at the bottom end of the porcelain knob. The rectangular hollow circuit breaker porcelain knob is characterized in that the hollow part of the cross section of the porcelain body is rectangular. The porcelain knob has the advantages of high intensity and capability of meeting the connection requirement on connecting the wires at the back side of a mounting plate of the circuit breaker.
Description
Technical field
The utility model relates to appliance field, relates to circuit breaker, specifically relates to the porcelain knob on the circuit breaker.
Background technology
Has porcelain knob on the circuit breaker, porcelain knob is the parts of supports contacts and contact knife, porcelain knob is installed on the mounting panel, in the prior art, for weight reduction, be convenient to wiring and use at circuit breaker mounting panel rear side, the porcelain knob that has a kind of inside to have hollow-core construction, the hollow-core construction of porcelain knob is circular like this, because the area that inner hollow parts accounts for is bigger, such porcelain knob has had the not high shortcoming of intensity again.
Summary of the invention

The technical solution of the utility model is achieved in that the hollow circuit breaker porcelain knob of rectangle, comprise the porcelain knob body, described porcelain knob body is middle porcelain structure with hollow parts, the hollow parts lower ending opening is characterized in that in the bottom of porcelain knob: the hollow parts of the cross section of described porcelain knob body is rectangular.
The beneficial effects of the utility model are: such porcelain knob has the intensity height, can also satisfy and be convenient to the advantage that wiring requires in the wiring of circuit breaker mounting panel rear side.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of the hollow porcelain knob of the utility model circuit breaker.
Wherein: 1, porcelain knob body 2, hollow parts
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the hollow circuit breaker porcelain knob of rectangle comprises porcelain knob body 1, and described porcelain knob body 1 is middle porcelain structure with hollow parts, the hollow parts lower ending opening is characterized in that in the bottom of porcelain knob: the hollow parts 2 of the cross section of described porcelain knob body 1 is rectangular.
