Abstract
The utility model relates to a single-phase two-pole small-sized plug-pull type circuit breaker, which comprises a base and a circuit breaker body inserted on the base, wherein the base and the circuit breaker body are also connected through a thread connection device. The single-phase two-pole small-sized plug-pull type circuit breaker adopts thread connection to lock the circuit breaker body and the base, which can prevent the circuit breaker from generating displacement between an inserting pin and an inserting sleeve in normal opening and closing process, accident potential of generating spark, looseness between the inserting pin and the inserting sleeve, and the like due to bad contact between the inserting pin and the inserting sleeve of the circuit breaker is avoided, the single-phase two-pole small-sized plug-pull type circuit breaker also has the function of preventing a plug-pull interlocking mechanism from false actions as for a small-sized circuit breaker with the plug-pull interlocking mechanism, the single-phase two-pole small-sized plug-pull type circuit breaker also has the function of preventing non-anticipated pulling, and the use is safer.
Description
Technical field
The utility model relates to a kind of single-phase two minimal type plug-in circuit breakers.
Background technology
Along with the improvement of residenter house condition, miniature circuit breaker enters family in a large number and uses, and power supply department needs a kind of single-phase two utmost point plug-in type miniature circuit breakers in a large number to the improvement of resident's ammeter box.This circuit breaker mainly is made up of breaker body and pedestal, and the circuit breaker of some form increases a plug interlinked mechanism between body and pedestal.
Because this type of circuit breaker generally is applicable to family expenses and similar site, and be located in ammeter box or the termination rack more, not only operate the frequency than higher, and close branch operation each time normally and all can make pin and sleeve produce displacement, make the pin and the sleeve loose contact of circuit breaker, thereby accident potential such as sparking, pin and sleeve be loosening are arranged; For the miniature circuit breaker with plug interlinked mechanism form, when displacement reached certain value, its interlinked mechanism made circuit breaker tripping, influences normal power supply; Simultaneously, this type of circuit breaker also has by the possibility that other people pull out away easily, influences user's normal use, and power supply department is caused unnecessary trouble.
The utility model content
The technical problems to be solved in the utility model provides the single-phase two minimal type plug-in circuit breakers that are connected firmly between a kind of breaker body and the pedestal, can avoid loose contact, can prevent from again to be pulled out away easily, to overcome the technical problem that exists in the prior art by other people.
The utility model is by the following technical solutions:
A kind of single-phase two minimal type plug-in circuit breakers comprise pedestal and the inserting breaker body in pedestal, and described pedestal also is connected by screw connection with breaker body.
Be threaded because more, can prevent that circuit breaker from producing displacement between pin and the sleeve in normal occlusion branch process, make the pin of circuit breaker and sleeve loose contact and produce sparking, pin and sleeve and accident potential such as become flexible than circuit breaker of the prior art; For having the miniature circuit breaker that plugs interlinked mechanism, the function that prevents to plug the interlinked mechanism misoperation is arranged also; The utility model also has and prevents unexpected function of pulling out away, uses safer.
Preferably, also comprise the plug interlinked mechanism, be located at described pedestal and breaker body junction.
Preferably, respectively be provided with lug on described pedestal and the breaker body, described screw connection is positioned at lug.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, single-phase two minimal type plug-in circuit breakers comprise the pedestal 3 of breaker body 1 and inserting with it, and pedestal 3 is provided with wiring pile, and circuit breaker can be connected in the circuit by this wiring pile, be provided with operating mechanism and dynamic/static contact in the breaker body 1, be used for the break-make of control circuit.When breaker body 1 left pedestal 3, circuit was to be in visual off-state.Preferably, be provided with plug interlinked mechanism 2 in the junction of breaker body 1 and pedestal 3, before breaker body 1 is pulled out from pedestal 3, the operating mechanism of this plug interlinked mechanism 2 in can interlock breaker body 1, dynamic/static contact is separated with open circuit, make operation safer.
Breaker body 1 is respectively equipped with lug 6,7 with the side of pedestal 3, is provided with screw 5 and nut 4 in the lug 6,7, thereby realizes being threaded of breaker body 1 and pedestal 3, also can be connected by tapping screw.
During use, breaker body 1 is inserted pedestal 3, and screw-in screw 5 gets final product; In the time of need extracting, should earlier screw 5 be withdrawed from, just breaker body 1 can be pulled up, operation is very easy.The utility model adopts be threaded locking breaker body and pedestal, can prevent that circuit breaker from producing displacement between the pin sleeve in normal occlusion branch process, makes the pin of circuit breaker produce sparking, pin and sleeve with the sleeve loose contact and accident potential such as becomes flexible; For having the miniature circuit breaker that plugs interlinked mechanism, the function that prevents to plug the interlinked mechanism misoperation is arranged also; The utility model also has and prevents unexpected function of pulling out away, uses safer.
Claims (3)
1. single-phase two minimal type plug-in circuit breakers comprise pedestal and the inserting breaker body in pedestal, and it is characterized in that: described pedestal also is connected by screw connection with breaker body.
2. single-phase two minimal type plug-in circuit breakers according to claim 1 is characterized in that: also comprise the plug interlinked mechanism, be located at described pedestal and breaker body junction.
