It is widely used in electricity consumption and distribution. The vacuum circuit breaker is mainly composed of a vacuum arc extinguishing chamber and an opening and closing operating mechanism, and has the advantage of fast opening and closing speed.
[0003] After searching, a Chinese patent application with application announcement number CN208422770U discloses a new type of vacuum circuit breaker, including a utility pole and a vacuum circuit breaker body.

[0015] The beneficial effects of the present invention are:
[0016] 1. The present invention provides a first wire-bundling mechanism. When the vacuum circuit breaker is in operation, the closing button and the opening button are used to close and open the vacuum circuit breaker. During this period, when wiring the components inside the vacuum circuit breaker, one end of the wire will connect the components inside the vacuum circuit breaker, and the other end of the wire will be connected to the terminal board through the first wire-bundling mechanism. The other end of the wire will be installed on the terminal board through two limiting rollers, the first wire-bundling roller and the second wire-bundling roller in sequence. Since the first wire-bundling roller and the second wire-bundling roller are arranged in a straight line, the wire will be distributed in an S shape under the action of the first wire-bundling roller and the second wire-bundling roller.

When the first wire harness mechanism is used to tighten and constrain the wire, the first wire harness roller and the second wire harness roller will rotate under the action of the wire tension. At this time, the two turntables will rotate with the rotation of the first wire harness roller and the second wire harness roller, and the pin will rotate in a circle with the center of the turntable as the center. At this time, the push rod will drive the push plate to swing back and forth under the action of the pin and the sleeve. At this time, the push plate will squeeze the airbag when it swings back and forth, and the gas inside the airbag will be squeezed. After being squeezed, the gas will be transported to the inside of the squeeze pad through the conduit. The air pressure inside the squeeze pad will increase with the input of gas. At this time, the squeeze pad will bulge under the action of the air pressure, and the bulged squeeze pad will act on the wire. Since the squeeze pad is made of flexible material, the squeeze pad can protect the wire while squeezing it. The squeezing of the squeeze pad can effectively tighten the wire, so as to facilitate the restraint of the wire, thereby improving the wiring effect of the wire and preventing the wire from falling off during connection, thereby affecting the operation of the vacuum circuit breaker.

Since the first wire bundling roller 21 and the second wire bundling roller 23 are distributed in a straight line, the wire will be on the first wire bundling roller. 21 and the second wire roller 23 are S-shaped. Therefore, the cooperation between the first wire roller 21 and the second wire roller 23 can effectively tighten the wire, and the setting of multiple limit openings 14 can independently set the wire.

At the same time, by tightening the wire, the gravity of the wire can be prevented. The wires are dragged, and thus fall off during wiring, thereby affecting the operation of the vacuum circuit breaker. When the wires are tightened and constrained by the first wire harness mechanism 15, the first wire harness roller 21 and the second wire harness roller 23 rotate under the action of the wire tension. At this time, the two turntables 25 rotate with the rotation of the first wire harness roller 21 and the second wire harness roller 23, and the pin 26 rotates in a circle with the center of the turntable 25 as the center. At this time, the push rod 28 drives the push plate 29 to swing back and forth under the action of the pin 26 and the shaft sleeve 27. At this time, the push plate 29 squeezes the airbag 30 when it swings back and forth. , and the gas inside the airbag 30 will be transported to the inside of the squeezing pad 34 through the conduit 35 after being squeezed. The air pressure inside the squeezing pad 34 will increase with the input of gas. At this time, the squeezing pad 34 will bulge under the action of the air pressure, and the bulged squeezing pad 34 will act on the wire. Since the squeezing pad 34 is made of flexible material, the squeezing pad 34 can protect the wire while squeezing the wire. Therefore, the squeezing of the squeezing pad 34 can effectively tighten the wire, so as to facilitate the restraint of the wire, thereby improving the wiring effect of the wire and preventing the wire from falling off during connection, thereby affecting the operation of the vacuum circuit breaker.
