Description
Technical field
The utility model relates to appliance field, in particular, relates to a kind of circuit breaker.
Background technology
Circuit breaker refers to the electric current that can close, carry and cut-off under normal loop condition, and can close, the switching device of carrying and the electric current under cut-offfing abnormal loop condition (comprising short circuit condition) in official hour.
Then household circuit breaker is fixed on body of wall or on fixed head after normally being installed by whole breaker body, disclose in the Chinese patent of " circuit breaker " consistent is called as the patent No. is 201320036036.6, power line is accessed by one end power end, other end load end picks out load line, at power end or load end all by live wire, zero line and bottom line three binding posts, and cause short circuit phenomenon to prevent the spark occurred when circuit breaker is jumped disconnected between each terminal from splashing, insulating barrier is equipped with between each adjacent binding post, the set-up mode of insulating barrier and circuit breaker has detachable and fixed form two kinds, convenient in order to make when repairing binding post, prevent insulating barrier and screwdriver from interfering, insulating barrier and circuit breaker are arranged to detachablely more be obtained extensive use.
But in prior art, the set-up mode that removably connects of circuit breaker and insulating barrier is very simple, usually be exactly the fit system of simple slide block and chute, no doubt the effect of fast demountable is met, but owing to being directly single grafting, thus cause patching end and owing to lacking frictional force, disengaging occurring and can get loose of insulating barrier and circuit breaker.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of insulating barrier can the circuit breaker of firm dismounting.
For achieving the above object, the utility model provides following technical scheme: a kind of circuit breaker of dismantled and assembled insulating barrier, comprise housing, the opposite ends of described housing is provided with power input and load end, described power input and load end are equipped with zero line binding post, hot terminal and ground wire binding post, described power input and load end are all removably connected with the insulating barrier that adjacent binding post can be separated, the dovetail groove of the break-through be interval between adjacent line terminals is provided with in described housing, being provided with in described dovetail groove can by the elastic portion of insulating barrier compacting in dovetail groove.
By adopting technique scheme, adjacent binding post being kept apart by insulating barrier, prevents when circuit breaker is jumped disconnected suddenly, Mars vibration occurs between adjacent binding post and occurs the danger of short circuit; And the removably of insulating barrier and circuit breaker can be crossed, directly insulating barrier can be released in dovetail groove, realize dismounting easily, for maintenance circuit breaker provides convenient; And by being arranged on the elastic portion in dovetail groove, the insulating barrier compacting that can will insert in dovetail groove, decreases the probability that in use insulating barrier and circuit breaker get loose.
The utility model is optimized for further: described elastic portion comprises rubber bumps, and described rubber bumps is located on the inwall of dovetail groove.
By adopting technique scheme, by rubber bumps, the elastic variable of itself can be utilized, when insulating barrier inserts dovetail groove, extruded by insulating barrier automatically, and pressure is produced to insulating barrier, it is firmly fixed on dovetail groove, realizes the effect of simple operations.
The utility model is optimized for further: described rubber bumps is hemisphere.
By adopting technique scheme, hemispheric rubber bumps, when receiving extruding, is more prone to deform, and when inserting insulating barrier in dovetail groove, inserts more smooth.
The utility model is optimized for further: described elastic portion comprises the groove be located on the inwall of dovetail groove, and described groove can along the compacting block of described groove indentation or ejection by spring.
By adopting technique scheme, adopt the mode of spring and compacting block, achieve the another kind of mode of elastic portion, when compacting block receives extruding, can inside contract to groove automatically, and spring is compressed, spring can provide opposition by compacting block to insulating barrier simultaneously, makes the state of insulating barrier in dovetail groove more stable, firm.
The utility model is optimized for further: each seamed edge of described dovetail groove is all rounded down.
By adopting technique scheme, by each seamed edge at dovetail groove, all fillet being set, when it inserts insulating barrier, avoiding killing phenomenon, more smooth and easy when making to insert and extract out insulating barrier.
Compared with prior art, the utility model has following advantage: by being arranged on the elastic portion in the dovetail groove on housing, makes insulating barrier after insertion dovetail groove, can elastic portion compacting, patches more firm, decreases the probability occurring to get loose with housing.

Embodiment
With reference to drawings and Examples, the utility model is described further.
Be embodiment one with reference to attached Fig. 1 and 2: comprise the housing be made up of the upper shell 11 cooperatively interacted and lower house 12, the opposite ends of described housing is provided with power input 2 and load end 3, zero line terminals 41 is equipped with at the power input 2 of lower house 12 and load end 3, hot terminal 42 and ground wire terminals 43, described power input 2 and load end 3 are all removably connected with the insulating barrier (not shown in FIG.) that adjacent binding post can be separated, the dovetail groove 5 of the break-through be interval between adjacent line terminals is provided with in described housing, being provided with in described dovetail groove 5 can by the elastic portion of insulating barrier compacting in dovetail groove 5, described elastic portion comprises rubber bumps 6, described rubber bumps 6 is located on the inwall of dovetail groove 5, described rubber bumps 6 is in hemisphere, each seamed edge of described dovetail groove 5 is all rounded down.
When operating the dismounting of insulating barrier, very simple only need the direction along dovetail groove 5 directly insert just can, because each seamed edge at dovetail groove 5 all arranges fillet, when it inserts insulating barrier, avoid killing phenomenon, more smooth and easy when making to insert and extract out insulating barrier; And while insertion, insulating barrier will extrude rubber bumps 6, and the rubber bumps 6 that hemisphere is arranged is very easy to distortion when being subject to insulating barrier extruding, further adds the smoothness that slips into of insulating barrier; And after insulating barrier inserts and puts in place, the reaction force of rubber bumps 6 will be subject to, firmly by insulating barrier compacting in dovetail groove 5, decrease the probability that insulating barrier and dovetail groove 5 get loose.
See Fig. 3 and Fig. 4, be embodiment two: be with the difference part of embodiment one, described elastic portion comprises the groove 73 on the inwall being located at dovetail groove 5, and described groove 73 can along the compacting block 71 of the indentation of described groove 73 or ejection by spring 72.
Adopt the mode of spring 72 and compacting block 71, achieve the another kind of mode of elastic portion, when compacting block 71 receives extruding, can inside contract to groove 73 automatically, and spring 72 is compressed, spring 72 can provide opposition by compacting block 71 to insulating barrier simultaneously, makes the state of insulating barrier in dovetail groove 5 more stable, firm.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
