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.

In the daily maintenance, the most common problem is the problem that the side of being qualified for the next round of competitions or the side of being qualified for the next round of competitions is empty to open and burns out, and the reason that leads to empty to open and burn out, except that the overload operation, it is not hard up to lead to the wire contact to become flexible exactly to open the screw and heat up and burn out, but when the installation is empty to open, table incasement operating space is limited, and the screw is difficult to the circumstances of screwing up takes place occasionally, simultaneously also takes place the screw and too tightly and lead to the wire pressure break, thereby the current situation that the empty of opening is burnt out in the heating of the conducting ability of wire has been influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to: in order to solve the problems, the rapid wiring open in the meter box is provided.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides an empty opening of quick wiring in table case, includes air switch, the last wiring mouth of having seted up of air switch, wiring mouth department is equipped with the indent, it has the briquetting to stretch into in the indent, fixedly connected with connecting rod on the briquetting, fixedly connected with horizontal pole on the air switch, it has the dwang to articulate on the horizontal pole, the tip and the connecting rod fixed connection of dwang, dwang fixedly connected with connecting plate, the connecting plate rotates with the horizontal pole to be connected, the last driving piece to briquetting driven that is equipped with of air switch.

Preferably, the driving piece includes fixed connection's side piece on air switch's the lateral wall, the spout has been seted up on the side piece, sliding connection has the slider in the spout, it has the swinging boom to articulate on the slider, the swinging boom is articulated with the connecting plate, set up flutedly on the air switch, the welded spring in the recess, the tip and the slider lateral wall welding of spring.

Preferably, the outer wall of the pressing block is provided with an elastic insulating cushion block.

Preferably, a handle is arranged on the connecting rod.

Preferably, the runner extends from the side block all the way into the recess.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:

1. this application gives the slider through the spring the power can make the slider when removing in the spout, lead to the swinging boom rotatory to promote the dwang and rotate, consequently lead to the briquetting to stretch into the indent in the rotation of certain angle, thereby compress tightly the wire of wiring department, need not to use the bolt to compress tightly the wire of wiring department, thereby it is loose to need not anxious bolt loosen and lead to the wire, the phenomenon of opening circuit appears.

2. This application is corresponding through the shape of briquetting and wiring mouth, and the cushion that centers on the briquetting outer wall can compress tightly the wire of wiring mouth department, because the cushion possesses elasticity, thereby the too big wire damage of dynamics that can not appear compressing tightly when consequently the briquetting compresses tightly the wire, and the briquetting can effectual performance.
