Abstract
The utility model discloses an electric-shock protection structure for residual current circuit breakers and moulded case circuit breakers, which is characterized in that a wire incoming end and a wire outgoing end of a circuit breaker casing are respectively provided with a protective cover, each clamping wall between each two adjacent wiring grooves on the circuit breaker casing is provided with a strip-shaped chute, and the protective covers are correspondingly provided with strip-shaped projections plugged with the chutes. After wiring terminals are mounted, exposed portions of the wiring terminals can be fastened inside the protective covers, and then electric shock hidden dangers to human bodies can be further stopped. In addition, the electric-shock protection structure can be fastened, dismounted and mounted without additional tools, is simple in structure, does not need more manufacturing cost, and can be expanded and applied to various circuit breakers and relative devices.
Description
Technical field
The utility model relates to a kind of circuit breaker electrocution-proof protection structure, specifically a kind of electrocution-proof protection structure that is used for residual current circuit breaker and breaker of plastic casing.
Background technology
Circuit breaker is a kind of on-load switch; but on-load disjunction and connection circuit; short circuit and overload protection function are arranged; some has functions such as no-voltage trip, electric leakage simultaneously, and its overload function (heat is threaded off) realizes by bimetal leaf that generally short-circuit protection function (magnetic dropout) is realized by solenoid; common have air circuit, vacuum circuit-breaker, oil-minimum breaker, a bulk-oil circuit-breaker etc.; because of its defencive function perfect, the maintenance, easy to use, of many uses in electric utility.Be assemblied in the power distribution cabinet in its use of formal occasion more; but in the simple and easy electricity consumption occasion of majority; it directly uses as the switch of power consumption equipment; adopt bright dress mode, but present circuit breaker end of incoming cables and leading-out terminal all do not have the corresponding protection structure, very easily make operating personnel's contact lead-wire; especially the end of incoming cables is not passed through residual current circuit breaker as yet; more can not play a protective role, very easily cause corresponding electric shock accidents, have bigger Electrical Safety hidden danger.
The utility model content
At above defective; the purpose of this utility model provides a kind of residual current circuit breaker and breaker of plastic casing electrocution-proof protection structure; by the grafting protection structure that is complementary is set respectively on circuit breaker turnover line end and containment vessel thereof, to stop the potential safety hazard that the person easily gets an electric shock.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of residual current circuit breaker and breaker of plastic casing electrocution-proof protection structure; end of incoming cables and leading-out terminal at Shell of circuit breaker respectively are equipped with an over cap; on the double wall on the described Shell of circuit breaker between per two adjacent connecting grooves a bar shaped chute is set, corresponding being provided with is used for the bar shaped projection that plugs together with described chute on the described over cap.The part cross section that described bar shaped chute and described bar shaped projection plug together mutually is trapezoidal; The bar shaped projection start-up portion that is used to plug together on the described over cap does not have the trapezoid cross section; Described Shell of circuit breaker is provided with the cylindroid hole, is correspondingly provided with the oval cylinder that can insert described cylindroid hole on the described over cap.
The beneficial effect of residual current circuit breaker described in the utility model and breaker of plastic casing electrocution-proof protection structure is: can be after binding post is finished installation; its exposed part is fastened within the over cap; can further stop potential person electric shock hidden danger; fastening and dismounting need not other instrument; simple in structure; need not to drop into more cost of manufacture, its structure can be expanded and be applied to various circuit breakers and associated device.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the described Shell of circuit breaker protection against electric shock of a utility model embodiment structural representation;
Fig. 2 is the described over cap part-structure of a utility model embodiment schematic diagram;
Fig. 3 is that the described over cap A of the utility model embodiment is to view;

Embodiment
Shown in Fig. 1-4, residual current circuit breaker described in the utility model and breaker of plastic casing electrocution-proof protection structure, end of incoming cables on Shell of circuit breaker 1 and below leading-out terminal an over cap 2 respectively is installed, on the double wall on the Shell of circuit breaker 1 between per two adjacent connecting grooves 4 a bar shaped chute 5 is set, the circuit breaker that is used for three-phase four-wire system for shown in the present embodiment is provided with three chutes 5 altogether; Accordingly, correspondingly on the over cap be provided with three and be used for the bar shaped projection 6 that plugs together with chute 5; Be unlikely disengaging after making over cap 2 insert Shell of circuit breaker 1, the part cross section that described bar shaped chute 5 and described bar shaped projection 6 plug together mutually is trapezoidal as shown in Figure 4; In order to make projection 6 easier insertion chutes 5, the bar shaped projection start-up portion that is used to plug together on described over cap 2 does not have the trapezoid cross section simultaneously.Fastening in order to guarantee that over cap 2 and Shell of circuit breaker 1 plug together, on housing 1, be provided with cylindroid hole 9 simultaneously, the outer wall 8 of corresponding over cap 2 is provided with oval cylinder 10.
During use; electric power incoming line and outlet are respectively with after binding post 3 in the connecting groove 4 is connected; over cap is inserted along chute 5; and make oval cylinder 10 also finally insert cylindroid hole 9; finish fastening; power supply lead wire not exposed part self-shield covers U-shaped hole 7 and passes, and 2 on all protected lid of all alive exposed parts covers, thereby stops potential personal Danger Electric shock risk.
Claims (4)
