Abstract
The utility model discloses a kind of residual current circuit breaker lead-in wire protective cover, it comprises the following two kinds protective cover: the first protective cover comprises the shield body in Contraband font tabular, and shield body is followed successively by the first shield portion, the second shield portion and the 3rd shield portion from top to bottom; The inner side in the first shield portion is provided with the chuck with the terminal screw hole clamping on circuit breaker, the 3rd shield portion be provided with the patch jack edge clamping on circuit breaker buckle platform and the boss with the adjustment screw hole grafting on circuit breaker; The second protective cover changes on the first protective cover basis: a sidepiece of shield body is provided with side shield, and the top of side shield, sidepiece and bottom are connected with the first shield portion, the second shield portion and the 3rd shield portion respectively.Lead-in wire protective cover in the utility model is installed fixing reliably convenient, and production cost reduces greatly, is convenient to stock management simultaneously.
Description
Technical field
The utility model relates to a kind of lead-in wire protective cover, belongs to residual current circuit breaker field of structural design.
Background technology
In existing residual current circuit breaker, lead-in wire protective cover is mostly integral structure, needs the lead-in wire protective cover that four kinds different from one pole residual current circuit breaker to four pole residual current circuit breaker, and three poles and four pole residual current circuit breaker need screw to be installed on circuit breaker by protective cover.Trouble installed by this kind of lead-in wire protective cover, and needs at least fourth officer mould, and cost is high, is also unfavorable for stock management simultaneously.
Utility model content
To this, technical problem to be solved in the utility model is that the inconvenience of existing residual current circuit breaker lead-in wire protective cover is installed and stock management, and the problem that production cost is high.
The technical scheme realizing the utility model object is:
A protective cover for residual current circuit breaker, it comprises the following two kinds protective cover: the first protective cover comprises the shield body in Contraband font tabular, and described shield body is followed successively by the first shield portion, the second shield portion and the 3rd shield portion from top to bottom; The inner side in described first shield portion is provided with the chuck with the terminal screw hole clamping on circuit breaker, described 3rd shield portion be provided with the patch jack edge clamping on described circuit breaker buckle platform and the boss with the adjustment screw hole grafting on described circuit breaker; The second protective cover changes on the first protective cover basis described: a sidepiece of described shield body is provided with side shield, and the top of described side shield, sidepiece and bottom are connected with described first shield portion, described second shield portion and described 3rd shield portion respectively.
The utility model has positive effect:
Protective cover of the present utility model only need produce two kinds when producing, be convenient to stock management, only need two width production moulds simultaneously, save production cost, when mounted, two kinds of protective cover collocation use, as second protective cover only need be installed in one pole residual current circuit breaker, two pole residual current circuit breaker install first protective cover and second protective cover, three pole residual current circuit breaker install two the first protective covers and second protective cover, four pole residual current circuit breaker install three the first protective covers and second protective cover, specifically when fixing, by the chuck in shield body and the terminal screw hole clamping on circuit breaker, platform and patch jack clamping will be detained, make boss and the grafting of adjustment screw hole can complete fixing, fixing fast firm, there is good result of use.

Embodiment
Do to illustrate to concrete structure of the present utility model below in conjunction with Figure of description:
A kind of residual current circuit breaker lead-in wire protective cover, as shown in Figures 1 to 4, it comprises the following two kinds protective cover: the first protective cover comprises the shield body 1 in Contraband font tabular, and described shield body 1 is followed successively by the first shield portion 3 of shield portion 2, second and the 3rd shield portion 4 from top to bottom; The inner side in described first shield portion 2 is provided with the chuck 21 with terminal screw hole 51 clamping on circuit breaker 5, described 3rd shield portion 4 be provided with the patch jack 52 edge clamping on described circuit breaker 5 buckle platform 41 and the boss 42 with adjustment screw hole 53 grafting on described circuit breaker 5; The second protective cover changes on the first protective cover basis described: a sidepiece of described shield body 1 is provided with side shield 6, and the top of described side shield 6, sidepiece and bottom are connected with described first shield portion 2, described second shield portion 3 and described 3rd shield portion 4 respectively.The protective cover of the present embodiment only need produce two kinds when producing, be convenient to stock management, only need two width production moulds simultaneously, save production cost, when mounted, two kinds of protective cover collocation use, as second protective cover only need be installed in one pole residual current circuit breaker, two pole residual current circuit breaker install first protective cover and second protective cover, three pole residual current circuit breaker install two the first protective covers and second protective cover (as shown in Figure 4), four pole residual current circuit breaker install three the first protective covers and second protective cover, specifically when fixing, by the chuck 21 in shield body 1 and terminal screw hole 51 clamping on circuit breaker, platform 41 and patch jack 52 clamping will be detained, make boss 42 and adjustment screw hole 53 grafting can complete fixing, fixing fast firm, there is good result of use.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And these belong to connotation of the present utility model the apparent change of extending out or variation still belong to protection range of the present utility model.
