Abstract

The utility model discloses a modularized shell of a molded case circuit breaker, which comprises a basic module; the basic module comprises a main shell and a contact system and an operating mechanism arranged on the main shell; the main shell is further provided with an over-current protection module which comprises a shell and a functional assembly installed on the shell; and any one of the over-current protection module without an RCD (residual current device) and the over-current protection module with the RCD can be adopted as the functional assembly. In the modularized shell of the molded case circuit breaker, after the base of the molded case circuit breaker is modularized, the eight of the molded case circuit breaker with the RCD can be shortened, so that the consumption of insulating materials and non-ferrous metal such as conductor connectors and the like can be reduced; the structure is simple and the cost is low; and during the production process by manufacturers, the basic module can be assembled, and then the over-current protection module or the over-current protection module with the RCD can be spliced according to market requirement, so that the manufacturing process and the managing process can be more scientific.

Description

The modularization housing of breaker of plastic casing

Technical field

The utility model relates to a kind of circuit breaker, relates in particular to a kind of modularization housing of breaker of plastic casing.

Background technology

As everyone knows; Any breaker of plastic casing all has the plastic casing of an insulation; The inside is all installed and be included in to this insulation crust to the contact system of circuit breaker and coupled operating mechanism, overcurrent protection with control unit etc. and other release and indications as annex with auxiliary contact, Alarm contactor etc., thereby make complete whole of circuit breaker composition.

The ambroin shell of breaker of plastic casing comprises two parts of base and cover at least; And pedestal wherein is that the contact system of circuit breaker and the operating mechanism that is attached thereto, the overcurrent protection unique parts with control unit etc. are installed; The plastic base of tradition breaker of plastic casing is a monomer; When breaker of plastic casing will increase RCD and is creepage protection function; Because total height must increase, always make another independent plastic base to the circuit breaker of band RCD, doing the plastic base part that makes breaker of plastic casing like this must be that independently two monomers are distinguished band and are not with RCD; Or make the whole splicing of independent parts to RCD on former breaker of plastic casing; The height of such structure collectivity increases to some extent; The result that the overall height increase brings is the increase of the consumptions such as non-ferrous metal of insulating material, conductor adapting piece, causes production cost to increase.

The utility model content

The purpose of the utility model is to provide a kind of modularization housing of breaker of plastic casing, and it has simple in structure, and cost is low, can increase the characteristics of RCD module according to demand.

The purpose of the utility model is to realize through following technical scheme:

A kind of modularization housing of breaker of plastic casing; It comprises basic module; Said basic module comprises main casing and is installed in contact system and the operating mechanism on the main casing, wherein, tool overcurrent protection module is installed also on the said main casing; Said overcurrent protection module comprises housing and is installed on the functional unit on the housing, and said functional unit is not for any of the overcurrent protection module of the overcurrent protection module of RCD and band RCD.

Especially, said overcurrent protection module is any of Thermomagnetic type or smart electronics formula.

Especially, be extended with several mounting panels to a side on the said housing, offer through hole on the said mounting panel, corresponding mounting panel offers installing hole on contact system, passes through hole through hold-down screw housing is assembled on the contact system.

The beneficial effect of the utility model does; The modularization housing of said breaker of plastic casing the base moduleization of breaker of plastic casing after; Can make the height of the breaker of plastic casing of band RCD shorten 20～40mm (according to different circuit breaker rated current), thereby make the consumption of the non-ferrous metal etc. of insulating material, conductor adapting piece descend about 2.5%～7.5% respectively; Not only simple in structure, cost is low; And manufacturer in process of production, can assemble basic module earlier, adds the RCD module by market demand splicing overcurrent protection module or overcurrent protection then and get final product, and makes manufacture process and the management process science that more becomes.
