Description
Technical Field
The utility model relates to the field of low-voltage electric appliances, in particular to an air switch with a protection function.
Background
An air switch, also known as an air circuit breaker, is one type of circuit breaker. The switch can be automatically switched off as long as the current in the circuit exceeds the rated current. The air switch is an important electric appliance in a low-voltage distribution network and an electric power dragging system, and integrates control and multiple protection functions. Besides the contact and breaking of the circuit, the protection of short circuit, severe overload and undervoltage, etc. of the circuit or electrical equipment can be realized, and the protection device can also be used for starting the motor infrequently.
The existing air switch has no protection at the position of a wiring terminal, and once a bug easily causes short-circuit tripping at the wiring terminal or a hand accidentally touches the wiring terminal to cause personal injury.
SUMMERY OF THE UTILITY MODEL
The utility model solves the problems through the following technical scheme:
an air switch with a protection function, comprising: an air switch body and a toggle switch;
the air switch body is of a vertically symmetrical structure;
the toggle switch is connected with the air switch body;
the top and the bottom of the air switch body are respectively provided with a first groove, and the wall surface opposite to the first groove is provided with a jack;
a protection plate is arranged in the first groove and is just matched with the first groove;
two ends of the protection plate are respectively connected with a rotating shaft, and the rotating shaft is matched with the first groove;
a plurality of second grooves are formed in the protection plate; a partition plate is rotationally connected in the second groove;
the protection plate is also provided with a plurality of observation ports; the observation port is connected with a moving piece in a sliding way;
two arc-shaped grooves are formed in the wall surface of the observation port; two convex edges are arranged on the side wall surface of the moving sheet and are just matched with the arc-shaped groove.
Further, a third groove is formed in the moving plate.
The utility model has the following beneficial effects:
the utility model can effectively protect personal safety through the protection plate, avoid danger caused by mistakenly touching the air switch by people and play a good protection effect.

Detailed Description
Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those embodiments can be easily implemented by those having ordinary skill in the art to which the present invention pertains. However, the present invention may be embodied in many different forms and is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, components not connected to the present invention will be omitted from the drawings.
An air switch with a protection function, comprising: the air switch comprises an air switch body 1 and a toggle switch 2;
as shown in fig. 1, the air switch body 1 has a vertically symmetrical structure;
the toggle switch 2 is connected with the air switch body 1;
as shown in fig. 2, the top and the bottom of the air switch body 1 are respectively provided with a first groove 11, and the wall surface opposite to the first groove 11 is provided with an insertion hole 111;
as shown in fig. 3, a protection plate 12 is arranged in the first groove 11, and the protection plate 12 is just matched with the first groove 11;
two ends of the protection plate 12 are respectively connected with a rotating shaft 125, and the rotating shaft 125 is matched with the first groove 11;
a plurality of second grooves 121 are formed in the protection plate 12; a partition plate 122 is rotatably connected in the second groove 121, and adjacent connecting wires can be isolated by rotating the partition plate 122;
as shown in fig. 4, the protection plate 12 is further provided with a plurality of observation ports 123, and the position of each observation port 123 corresponds to the position of the connection terminal; the observation port 123 is connected with a movable piece 124 in a sliding manner, and the movable piece 124 can observe the condition of the wiring terminal;
as shown in fig. 5, two arc-shaped grooves 1231 are formed on the wall surface of the observation port 123; two convex edges 1241 are arranged on the side wall surface of the moving plate 124, and the convex edges 1241 are just matched with the arc-shaped grooves 1231.
Further, as shown in fig. 5, a third recess 1242 is formed on the moving plate 124 to facilitate a person to fasten the moving plate 124 and move.
In the description of the present technical solution, it should be specifically noted that, unless explicitly stated or limited otherwise, the terms "mounted," "connected," and "connected" used herein should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.
