Detailed Description

The utility model is further described below with reference to the accompanying drawings: as shown in the figure, a dc breaker comprises a breaker housing 1 and a cover body 2 which are detachably connected, wherein the cover body comprises a plurality of side plates 21 arranged on the periphery of a wiring row 91 or a shorting row, at least one side plate is provided with a baffle 22 which is detachably arranged, and the cover body comprises a first state of detaching the baffle when being installed at the load end of the breaker and a second state of retaining the baffle when being installed at the shorting end of the breaker. The baffle can be made of different materials or connected with the side plate through a fragile connecting part, but the baffle can be detached through knocking, hammering and the like when the baffle needs to be detached, and the fragile connecting part can be of a thinner structure and can also adopt a smaller connecting contact area, such as strip-shaped connection. A plurality of curb plates form the empty slot that the short link held, and the top of curb plate is equipped with the roof, when pulling down one side curb plate, the side direction forms an open slot and is used for the wire to pass through.

In this embodiment, as shown in the drawing, the side plate is provided with a connecting portion 23, and the thickness of the connecting portion is smaller than that of the side plate, and the connecting portion is disposed between the side plate and the baffle. The circumference of baffle is connected by connecting portion and curb plate, and connecting portion are comparatively fragile part, can fracture and take off the baffle when beating.

In this embodiment, as shown in the figure, the cover body is provided with a plurality of heat dissipation grooves 25. Has good heat dissipation and exhaust functions.

In this embodiment, as shown in the figure, the cover body is provided with a buckle 24, and the circuit breaker housing is provided with a boss 11 matched with the buckle. The buckle is installed and forms a locating fit installation structure with the boss relatively simply.

In this embodiment, as shown in the drawing, the circuit breaker housing is provided with a shorting bar 12, and a plurality of heat dissipation plates 121 are disposed on the shorting bar. The heat dissipation plate may be directly disposed on the shorting bar, or may be of a radiator type structure, that is, disposed on the bottom plate, and then the bottom plate is mounted on the heat dissipation plate.

In this embodiment, as shown in the figure, the cover body includes a first cover body 3 mounted at the short-circuit end of the circuit breaker, a latch 31 is disposed on the inner wall of the first cover body, and a mounting groove 13 in plug-in fit with the latch is disposed on the circuit breaker housing. The installation stability is increased, and the falling-out is prevented.

In this embodiment, as shown in the drawing, the outer wall of the first cover is provided with a fixing groove 32 for installing the arc-shaped plate. The installation of the arc-shaped plate is convenient.

In this embodiment, as shown, the housing includes a second housing 4 mounted to the load end of the circuit breaker, with a spacer 41 provided therein for separating adjacent rows of wires. Increasing the creepage distance prevents short circuits.
