Abstract

The utility model relates to a plastic housing breaker and a thermal overload releaser system of the plastic housing breaker. The breaker and the system mainly overcome problems that the thermal overload releaser system of the conventional plastic housing breaker is complex in processing and assembly and has large consumption of a copper material. The system is characterized in that a connecting plate is an integrated structure and comprises a heating part, a connecting part and an electrifying part disposed at two ends, and the connecting plate, a bimetal and an iron core are in rivet connection. The system is advantaged in that the integrated connecting plate and the rivet connecting manner enable the consumption of the copper material to be reduced and allow processing and assembly processes to be simple.

Description

Breaker of plastic casing and hot tripping system thereof
Breaker of plastic casing and hot tripping system thereof
Technical field
The utility model relates to a kind of hot tripping system, is specifically related to the hot tripping system of a kind of breaker of plastic casing.
Background technology
Breaker of plastic casing is protective device important in the low-voltage distribution system, and it plays connection, disjunction running current in low-voltage distribution system, and having simultaneously provides short-circuit protection, overload protection, under voltage protection etc. to AC network circuit and power consumption equipment.The hot tripping system design of traditional breaker of plastic casing with the copper material amount large and processing and assembly technology complicated: it is pieced together chain by thermal element, bimetal leaf, back seat by electric welding processing repeatedly and forms, and hot tripping system to be connected with moving contact be to realize by the fastened by screw mode.Have like this that the copper material consumption is large, processing and assembly technology is complicated, during work consuming, high, the temperature rise of consuming electric power, power consumption is not easy the shortcomings such as control.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of breaker of plastic casing hot tripping system, solves that the copper material consumption is large, processing and assembly technology is complicated, the problem such as during work consuming.
The technical scheme that the utility model adopts: a kind of hot tripping system of breaker of plastic casing, include connecting plate, iron core, described connecting plate is the integral type structure, the power part that comprises heating part, coupling part and be positioned at two ends divides, and described connecting plate, bimetal leaf, iron core pass through rivet.
The heating part of described connecting plate is identical with the thickness of coupling part, and described heating part is narrower than the width of coupling part.
Described iron core, bimetal leaf lay respectively at the both sides of connecting plate heating part.
A kind of breaker of plastic casing with described hot tripping system, include housing and be installed on housing interior operating mechanism, arc quenching system, contact system, hot tripping system, described contact system comprises moving contact, fixed contact, described moving contact is connected with hot tripping system, described hot tripping system includes connecting plate, bimetal leaf, iron core, described connecting plate is the integral type structure, the power part that comprises heating part, coupling part and be positioned at two ends divides, and described connecting plate, bimetal leaf, iron core pass through rivet.
Described hot tripping system and moving contact are formed by connecting by the electric welding mode.
Described hot tripping system one end is provided with backing plate, and described backing plate is fixedly connected with connecting plate, and the material of described backing plate is iron material.
The beneficial effects of the utility model are: adopt above scheme, the connecting plate of described hot tripping system is the integral type structure, and connecting plate, bimetal leaf, iron core, rivet etc. are by rivet, not only so that product copper material consumption is few but also processing and assembly technology are simple.
Description of drawings
Fig. 1 is the hot tripping system structural representation of the utility model.
Fig. 2 is the utility model breaker of plastic casing structural representation.
The hot tripping system of 1-among the figure, the 2-connecting plate, the 3-bimetal leaf, the 4-iron core, the 5-rivet, the 6-moving contact, the 7-backing plate, the 21-heating part, the 22-coupling part, the 23-power part divides
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of hot tripping system of breaker of plastic casing, include connecting plate 2, bimetal leaf 3, iron core 4, described connecting plate 2 is by a pressing and bending moulding of copper coin material, be the integral type structure, the power part that comprises heating part 21, coupling part 22 and be positioned at two ends divides 23, and described bimetal leaf 3, iron core 4 are by rivet 5 disposable being riveted on the connecting plate 2.
The heating part 21 of described connecting plate 2 is identical with the thickness of coupling part 22, and described heating part 21 is narrower than the width of coupling part 22.Therefore the resistance of heating part 21 when electric current passes through more easily heating, makes the bimetal leaf temperature distortion crooked greater than coupling part 22, reaches the dropout purpose.
Described iron core 4, bimetal leaf 3 lay respectively at the both sides of connecting plate heating part 21.
Than the hot tripping system of traditional breaker of plastic casing, the structure of terminal block 2 integral types has not only greatly reduced the consumption of copper coin material, and make processing and assembly technology simpler; The connected mode of riveted joint, not only easy to process, and compare with the connected mode of electric welding, more firm, compare with the mode that screw is fixedly connected with, saved screw, Cost reduction.
As shown in Figures 1 and 2, a kind of breaker of plastic casing with described hot tripping system, include housing and be installed on housing interior operating mechanism, arc quenching system, contact system, hot tripping system, described contact system comprises moving contact 6, fixed contact, described moving contact 6 is connected with hot tripping system, described hot tripping system includes connecting plate 2, bimetal leaf 3, iron core 4, described connecting plate 2 is the integral type structure, the power part that comprises heating part 21, coupling part 22 and be positioned at two ends divides 23, and described connecting plate 2, bimetal leaf 3, iron core 4 are by rivet 5 riveted joints.
Described hot tripping system one end is provided with backing plate 7, and described backing plate 7 is fixedly connected with connecting plate 2, and the material of described backing plate 7 is iron material.
Described hot tripping system and moving contact 6 are formed by connecting by the electric welding mode.The screw fixed form of comparing traditional, not only easy to process, and avoided the existence of contact resistance and the power consumption that produces, reduced the temperature rise of product.
