Abstract
The utility model relates to a circuit breaker, and particularly to a DC circuit breaker. The DC circuit breaker comprises a housing. Side surfaces of the housing are provided with a terminal hole and wiring holes. The DC circuit breaker further comprises a dustproof safety structure and a protective cover. The dustproof safety structure is equipped on the terminal hole. The protective cover is equipped on one wiring hole. According to the structure of the DC circuit breaker, the dustproof safety structure which is obtained through combining a busbar and a cap is equipped on the terminal hole, and the protective cover is equipped on the wiring hole. Before the DC circuit breaker is used, a converge hole can be blocked by the busbar after a terminal is connected, and simultaneously a mounting hole is sealed for realizing a dustproof function. Simultaneously, a client does not require wiring and can directly use after the product is obtained, and therefore the use is facilitated. Because the wiring hole at one side of the DC circuit breaker is not used, the wiring hole is sealed by the protective hole, thereby realizing a dustproof and protective function, and integrally improving safety of the DC circuit breaker.
Description
Technical field
The utility model relates to a kind of circuit breaker, especially a kind of dc circuit breaker.
Background technology
Circuit breaker (English name: circuit-breaker; circuit breaker) refer to close and close, carry and cut-off electric current under the normal loop condition, and can close close, carrying and cut-off the switching device of the electric current under the unusual loop condition (comprising short circuit condition) in official hour.Circuit breaker can be used to distribute electric energy; do not start asynchronous motor continually; power circuit and motor etc. are carried out protection, can automatic shutdown circuit when serious overload or short circuit and fault such as under-voltage take place for their, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And behind the disjunction fault current, generally do not need to change parts.At present, obtained to use widely.Circuit breaker generally is made of contact system, arc quenching system, operating mechanism, release, shell etc.When short circuit, the magnetic field that big electric current (general 10 to 12 times) produces overcomes reaction spring, release pull operation mechanism action, the instantaneous tripping operation of switch.When overload, it is big that electric current becomes, the caloric value aggravation, and bi-metal plate deformed is to a certain degree pushing mechanism action (electric current is more big, and operate time is more short).
And dc circuit breaker is the circuit breaker for the conversion of direct current system operational mode or failure removal, present dc circuit breaker is cumbersome in time wiring, when in use, dc circuit breaker when in use, be to use after two terminals need being connected, when using connection, it is not need wiring that wiring hole is on one side arranged, but dc circuit breaker in the market, terminal and wiring hole all expose, and not only deposit dust easily, and potential safety hazard arranged, when in use neither be very convenient, the client manually with after the terminal connection, just can put into the circuit wiring and use.
Summary of the invention
The purpose of this utility model is, a kind of dc circuit breaker easy to use, safe is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of dc circuit breaker; comprise housing, the housing side is provided with terminal hole, wiring hole, also comprises dustproof safeguard construction, over cap; dustproof safeguard construction is arranged on the terminal hole, and over cap is arranged on the wiring hole.
Of the present utility modelly further be set to: described terminal hole comprises installing hole, the hole of confluxing, and dustproof safeguard construction comprises capping, bus-bar, and bus-bar is pegged graft with the hole of confluxing and cooperated, and capping cooperates with the installing hole grafting.
Of the present utility modelly further be set to: described installing hole is circular hole, and capping is a cylindrical cover, is inserted in the installing hole, the Kong Weiyi elongated slot that confluxes, and bus-bar is sheet, is inserted in the hole of confluxing.
Of the present utility modelly further be set to: described over cap is a convex shape over cap, is embedded on the wiring hole.
The dustproof safeguard construction that said structure utilizes bus-bar and capping to constitute; it is arranged on the terminal hole; at wiring hole over cap is set; so before use; after can earlier terminal being connected; with the bus-bar hole shutoff of will confluxing, seal installing hole simultaneously, reach the dustproof purpose; simultaneously; the client does not just need wiring again, can directly use after taking product, uses easily; because the wiring hole of dc circuit breaker one side does not need to use; therefore use the over cap involution, just can reach purpose dustproof and protection, integral body has improved fail safe of the present utility model.
Description of drawings
Fig. 1 is the structural representation of present embodiment;
Embodiment
With reference to figure 1 as can be known, a kind of dc circuit breaker of the utility model comprises housing 1; the housing side is provided with terminal hole, wiring hole 13, and described terminal hole comprises installing hole 11, the hole 12 of confluxing, and dustproof safeguard construction comprises capping 2, bus-bar 3; installing hole 11 is circular hole; capping 2 is a cylindrical cover, is inserted in the installing hole 11, and the hole 12 of confluxing is an elongated slot; bus-bar 3 is sheet; be inserted in the hole 12 of confluxing, described over cap 4 is a convex shape over cap, is embedded on the wiring hole 13.
This real embodiment is a 4P circuit breaker; because when in use; at least want the circuit breaker of 2P just can finish the function of dc circuit breaker; therefore in the utility model; bus-bar normally two bus-bars is wholely set; convenient when in use; simultaneously; because dc circuit breaker when in use, is to need to use connecting hole, therefore on structure; the wiring hole that only need seal a side gets final product; certainly, if reach better dustproof effect, it is also passable that the both sides wiring hole all arranges over cap.
Obviously, above-described embodiment only be for explanation clearly do for example, and be not restriction to execution mode.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here need not also can't give all execution modes exhaustive.And the apparent variation of being extended out thus or change still are in the protection range of the present utility model.
