Abstract
The utility model relates to a residual current operated circuit breaker, in particular to the structure of a residual current operated circuit breaker for preventing the movement of a tin melting block. According to the technical scheme of the utility model, the structure of the residual current operated circuit breaker for preventing the movement of the tin melting block is characterized in that a grid region positioned right below the welding joint point of a contact plate and a current-carrying conductor is arranged on the shell of a circuit breaker. The grids of the grid region can be melted along with the tin melting block when the tin melting block falls onto the grid region, so as to be bonded with the tin block. Due to the adoption of the above technical scheme of the utility model, the defect in the prior art can be overcome, while the movement of the tin melting block during the welding process is well avoided. Therefore, the potential troubles of products in performance can be avoided.
Description
Technical field
The utility model relates to a kind of residual current action breaker, refers to especially the structure that prevents molten block tin activity of residual current action breaker.
Background technology
In electronic type RCBO, because becoming more and more popular, modularized design make RC componentry wire use more the rigid line moulding process, and this makes the assembly technology difficulty increase, and has therefore derived the soldering technique of current carrying conductor.
The total process of assembling of RC element carries out soldering inevitably can produce the situation that molten block tin drops, and if as the electronic type product, electric conductor uncontrollable movement in product is arranged, what short circuit between circuit board component will occur may.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of and can finely overcome the molten block tin that produces and the structure that prevents molten block tin activity on the novel residual current action breaker of the properties of product potential problem that causes in welding process.
in order to realize above purpose, the utility model is by the following technical solutions: the structure that prevents molten block tin activity on a kind of residual current action breaker, include Shell of circuit breaker, contact plate and current carrying conductor, described contact plate is fixed or is plugged and is arranged on Shell of circuit breaker, the contact plate extension is provided with a welding ends, one end of described current carrying conductor is welded on the welding ends of contact plate, it is characterized in that: on described Shell of circuit breaker and be positioned at contact plate and current carrying conductor be welded to connect a little under be provided with a grid region, the grid of this grid region can melt on molten block tin drops it the time thereupon and consist of bonding setting with block tin.
By adopting such scheme, the molten block tin that drops in the time of can making an end of current carrying conductor be welded on the welding ends of contact plate drops in grid region, and grid is melted, block tin and grid are bonded together, can well overcome so the molten block tin that produces and the problem of the properties of product hidden danger that causes in welding process.
The utility model further arranges: described contact plate extends the welding ends that arranges and is provided with draw-in groove, and current carrying conductor is welded in draw-in groove; Grid and the Shell of circuit breaker of described grid region are wholely set.
In above-mentioned further scheme, draw-in groove is set for increasing the operating performance of soldering technique, increases current carrying conductor soldering firmness.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of the utility model embodiment Shell of circuit breaker reaction grid;
Fig. 3 is the structural representation of the utility model embodiment contact plate.
Embodiment
as Fig. 1-shown in Figure 3, the structure that prevents molten block tin activity on a kind of residual current action breaker, include Shell of circuit breaker 1, contact plate 2 and current carrying conductor 3, described contact plate 2 fixes or plug is arranged on Shell of circuit breaker 1, contact plate 2 extensions are provided with a welding ends 21, one end of described current carrying conductor 3 is welded on the welding ends 21 of contact plate 2, above-mentioned technical characterictic is also comparatively common in the prior art, so here we just have not been described in detail, in the present embodiment, on described Shell of circuit breaker 1 and be positioned at contact plate 2 and current carrying conductor 3 be welded to connect a little 4 under be provided with a grid region 11, the grid 111 of this grid region 11 can melt on molten block tin drops it the time thereupon and consist of bonding setting with block tin, the utility model adopts such scheme, the molten block tin that drops in the time of can making an end of current carrying conductor 3 be welded on the welding ends 21 of contact plate 2 drops in grid region 11, and with grid 111 fusings, block tin and grid 111 are bonded together, can well overcome so the molten block tin that produces and the problem of the properties of product hidden danger that causes in welding process.
In the utility model embodiment, described contact plate 2 extends the welding ends 21 that arranges and is provided with draw-in groove 211, and current carrying conductor 3 is welded in draw-in groove 211, draw-in groove 211 is set for increasing the operating performance of soldering technique, increases current carrying conductor 3 soldering firmness; In the present embodiment, the grid 111 of described grid region 11 is wholely set with Shell of circuit breaker 1.
