Abstract
The utility model relates to a small size breaker external shell which is provided with a cross groove on one side. The cross groove leads to two sides of the external shell. The utility model has simple construction, which can achieve good radiating effect for the small size breaker without bothering increasing volume or changing die technique.
Description
The utility model relates to a kind of miniature circuit breaker shell.
Miniature circuit breaker be a kind of overcurrent protection disconnect, it is except one pole uses, normally the two poles of the earth, three utmost points or four utmost points or a plurality of one pole parallel side by side are used.Owing to be a kind of overcurrent protection disconnect, and volume is little, this miniature circuit breaker heat that its thermal tripping mechanism produces in parallel side by side is used is difficult to distribute, and then influences its performance.
The purpose of this utility model is to solve the problems referred to above that existing miniature circuit breaker technology exists, and provides a kind of and can promote the particularly miniature circuit breaker shell of parallel side by side use miniature circuit breaker heat radiation of miniature circuit breaker.
The technical scheme that realizes the utility model purpose is such.A kind of miniature circuit breaker shell, its side is provided with translot, and translot leads to the both sides of shell side.When the miniature circuit breaker parallel side by side that has adopted this miniature circuit breaker shell was used, this translot promptly became radiating groove, and the heat that its thermal tripping mechanism produces can distribute from this translot through shell.
Aforesaid miniature circuit breaker shell, the quantity of the translot that is provided with on the side of its shell are one or two or many and two.
The utility model is owing to be provided with the translot that leads to both sides, shell side on the one side, this translot is as radiating groove, can make be in employing that parallel side by side uses the heat that produces of the miniature circuit breaker thermal tripping mechanism of this miniature circuit breaker shell distribute from this translot through shell.It simple in structure need not increase volume, also need not change its molding process, can reach better heat radiating effect.
Introduce embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model example structure schematic diagram one.
Fig. 2 is the utility model example structure schematic diagram two.
Miniature circuit breaker shell as shown in Figure 1, 2, shell 1 one sides are provided with translot 1-1, translot 1-1 leads to the both sides of side, the quantity of this translot 1-1 can be one two or more.Among the figure: the 2nd, the handle of operating system.This miniature circuit breaker shell is applicable to the miniature circuit breaker of existing various models.
Claims (2)
1. miniature circuit breaker shell, it is characterized in that: a side of shell is provided with translot, and translot leads to the both sides of shell side.
2. miniature circuit breaker shell according to claim 1 is characterized in that: the quantity of described translot is one or two or more than two.
