Description
Technical Field
The utility model belongs to the technical field of low-voltage electric appliances, and particularly relates to a wiring protection device of an intelligent miniature circuit breaker.
Background
When the existing intelligent miniature circuit breaker applied to a 5G cabinet is automatically switched on and off, a connecting cable easily interferes with the switching-on and switching-off actions of a switching-on and switching-off button, and a switch is caused to be in sliding buckle in serious cases. The current solution is to add a similar cover structure around the button under the terminal of the breaker to separate the button from the cable and protect the button from the interference of the cable (for example, chinese patent No. CN112490084A adopts such a structure). However, such a structure arrangement can block the manual operation when the manual opening and closing operation is performed, so that the operation is inconvenient; particularly, when the circuit breaker is disassembled, the circuit breaker is disassembled by unlocking the buckle by pulling the button, and the existence of the cover can interfere the forced pulling of the button.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The first embodiment is as follows:
as shown in fig. 1-4, the wiring protection device for the intelligent miniature circuit breaker comprises a circuit breaker body 3, a panel 4 which is vertically arranged at a wiring end of the circuit breaker body 3 and is provided with a wiring hole 6, and a button 1 which is arranged below the panel 4 and is used for operating opening and closing actions; a cable 5 is inserted in the wiring hole 6; the panel 4 is provided with an anti-interference mechanism for separating the button 1 from the cable 5, the anti-interference mechanism is positioned between the wiring hole 6 and the button 1 and can be inserted into or pulled out of the circuit breaker body 3; the interference preventing mechanism comprises a slot 41 and an inserting plate 2; the slot 41 is arranged on the panel 4 and is positioned between the button 1 and the wiring hole 6; the plug board 2 is transversely arranged in the slot 41 to separate the button 1 from the cable 5 and can be inserted into or pulled out of the breaker body 3 along the slot 41; the inserting plate 2 is made of a metal plate or a high-strength plastic plate, has certain strength and is not easy to deform completely so as to stably support the cable 5; when the inserting plate 2 is pulled out, the length of the inserting plate is greater than that of the inserting plate protruding out of the breaker body 3 when the button 1 is opened, so that the cable 5 can be more effectively blocked or separated, and the situation that the cable 5 bends downwards under the self gravity and presses the button 1 to influence the normal operation of the button 1 is avoided.
In the automatic operation process of the circuit breaker, the plug board 2 is pulled out of the slot 41, the button 1 is effectively separated from the cable 5, and the cable 5 can be prevented from interfering the automatic action of the button 1.
During manual operation, the inserting plate 2 can be pushed into the circuit breaker body 3 along the slot 41, so that the inserting plate 2 is no longer blocked above the button 1, and the manual operation of the button 1 is facilitated.
When the circuit breaker is pulled out, the inserting plate 2 is pushed into the circuit breaker body 3 along the slot 41, so that the inserting plate 2 is not blocked above the button 1 any more, the pulling-out of the button 1 cannot be interfered, and the circuit breaker can be smoothly pulled out of the cabinet body by pulling out the button 1 without interference.
Example two:
the difference between this embodiment and the first embodiment is:
the top of the head end (the end outside the circuit breaker body 3) of the plug board 2 is provided with a strip-shaped hole or a convex strip 21 for assisting the plug board 2 to pull out the slot 41. When the inserting plate 2 is pulled out, the inserting plate 2 can be pulled out only by inserting a straight screwdriver into the strip-shaped hole or clamping the straight screwdriver on the raised strips 21.
Example three:
the difference between this embodiment and the first or second embodiment is:
a bottom plate 7 which is arranged in the breaker body 3 and is positioned between the wiring hole 6 and the button 1 is transversely fixed below the panel 4; the bottom plate 7 is hollow and communicated with the slot, and the plug board 2 can be inserted into or pulled out of the bottom plate 7 along the slot 41. The bottom plate 7 can support and limit the inserting plate 2, the inserting plate 2 can slide in or slide out along the inner cavity of the bottom plate 7, and the upper surface and the lower surface of the inner cavity of the bottom plate 7 are in sliding fit with the upper surface and the lower surface of the inserting plate 2.
Example four:
the present embodiment is different from any one of the first to third embodiments in that:
in order to prevent the insertion plate 2 from completely falling out of the slot 41, the following structure is provided: both sides of the tail end of the inserting plate 2 are respectively concave to form a groove 22; two sides of the inner part of the bottom plate 7 are respectively provided with an elastic cantilever structure 71, and the end part of the elastic cantilever structure 71 protrudes towards the direction of the groove 22 to form a flange 72 matched with the groove 22; when the inserting plate 2 is pulled out of the inserting groove 41, the groove 22 is matched and positioned with the flange 72, and the inserting plate 2 is difficult to be pulled out completely; then the inserting plate 2 is pushed by force, the inserting plate 2 can push the elastic cantilever structure 71 to expand towards two sides, so that the flange 72 is disengaged from the groove 71, and the inserting plate 2 can be retracted into the bottom plate 7.
Example five:
the present embodiment is different from the fourth embodiment in that:
in order to prevent the insertion plate 2 from completely falling out of the slot 41, another structure is provided as follows: the width of the inner cavity of the bottom plate 7 is larger than that of the slot 41; the inserting plate 2 is a T-shaped plate with the tail end arranged in the bottom plate 7 and the width of the tail end larger than that of the inserting groove 41. Due to the arrangement of the structure, the part of the inserting plate 2 except the tail end can freely slide out of the slot 41, and the tail end of the inserting plate 2 is difficult to slide out of the slot 41 because the width of the tail end is larger than that of the slot 41, so that the aim of preventing the inserting plate 2 from completely falling out of the slot 41 (or completely falling out of the bottom plate 7) is fulfilled.
It is to be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
