Description

Technical Field

[0001] The present invention relates to a switch, and more particularly to a fast switch and its on-off mechanism. Background Art

[0002] Circuit breakers are often used to control the on-off of circuits on high-voltage or low-voltage lines. A circuit breaker generally includes components such as a spring energy storage mechanism, a moving contact, and a static contact. When it is necessary to close and connect the circuit, the spring energy storage mechanism drives the moving contact to move quickly to contact the static contact, thereby realizing the conduction of the circuit. The more energy the spring energy storage mechanism stores, the faster the moving contact moves, the shorter the closing response time, and the more it can meet the requirement of instant response. However, the faster the moving contact moves, the greater the impact force on the static contact, and the greater the reaction force received after the impact, which causes the moving contact to rebound and separate from the static contact, and thus generates frequent opening and closing vibrations between the moving contact and the static contact in a short time, thereby disturbing the circuit and affecting the normal operation of the circuit. This problem has not been well solved so far. Summary of the Invention

[0003] An object of the present invention is to provide an on-off mechanism for a fast switch, which can well adapt to the high-energy driving level of the spring energy storage mechanism to quickly conduct the circuit, but does not generate opening and closing vibrations of the circuit, thereby avoiding affecting the circuit.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] An on-off mechanism for a fast switch includes a first guiding portion and a second guiding portion that are parallel to each other. The first guiding portion includes a first insulating portion and a first conducting portion, and the second guiding portion includes a second insulating portion and a second conducting portion. The first conducting portion and the second conducting portion are disposed opposite to each other and are respectively connected to the incoming end and the outgoing end of the wire. A conducting slider is provided between the first guiding portion and the second guiding portion. When the conducting slider moves from between the first insulating portion and the second insulating portion to between the first conducting portion and the second conducting portion, the first conducting portion and the second conducting portion are conducted. When the conducting slider moves from between the first conducting portion and the second conducting portion to between the first insulating portion and the second insulating portion, the first conducting portion and the second conducting portion are insulated from each other. A limiting portion is provided at one end of the first conducting portion or / and the second conducting portion; the material of the limiting portion has buffering properties, and after the conducting slider collides with the limiting portion, the limiting portion can stop the conducting slider without causing it to rebound and separate from the first conducting portion and the second conducting portion.

[0006] Preferably, the first guiding portion and the second guiding portion are parallel plane or arc-shaped guiding plates, the guiding plates are formed by connecting an insulating material and a conducting material, the conducting slider is a cuboid or a cylinder and is located between the guiding plates, and insulating jackets are wrapped around both sides of the conducting slider along the moving direction.

[0007] Preferably, guide edges or additional guide plates are provided on both sides of the mutually parallel guide plates.

[0008] Preferably, a guide rod is provided between the mutually parallel guide plates, and the conductor slider is sleeved on the guide rod.

[0009] Preferably, the first guiding portion and the second guiding portion are guide rails, guide grooves are provided on both the upper and lower sides of the conductor slider, and the guide grooves are matched with the guide rails.

[0010] Preferably, the first guiding portion and the second guiding portion are guide rods, and two mutually parallel guide holes are provided on the conductor slider, and the guide rods are respectively located in the guide holes.

[0011] Another object of the present invention is to provide a quick switch, which can be quickly switched on without frequent on-off of the moving and static contacts at the moment of switching on.

[0012] A quick switch includes a switching mechanism, the switching mechanism is the switching mechanism of the above-mentioned quick switch, and a first driving mechanism is provided at one end of the first guiding portion or / and the second guiding portion, and a second driving mechanism is provided at the other end.

[0013] Preferably, the first driving mechanism and the second driving mechanism are spring ejection mechanisms.

[0014] Preferably, both the first driving mechanism and the second driving mechanism are electromagnetic driving mechanisms, a magnetic action portion is provided on the conductor slider, and the electromagnetic driving mechanism drives the conductor slider to move by acting on the magnetic action portion on the conductor slider through electromagnetic force.

[0015] Preferably, the limiting portion is a limiting plate or a limiting block.

[0016] The switching mechanism and the corresponding quick switch of the present invention limit the movement of the conductor slider through the first guiding portion and the second guiding portion, and both the first guiding portion and the second guiding portion are composed of an insulating portion and a conductor portion. The conductor portion is connected to the wire, so that the conductor slider can quickly move from the insulating portion to the conductor portion to conduct the circuit. The insulating portion plays a role in guiding and enabling the conductor slider to smoothly enter the conductor portion, so that a very strong driving force can be applied to the conductor slider to make it move forward at an extremely fast speed, and then it is blocked by the limiting portion on one side of the conductor portion and stops. Although there will be an impact with the limiting portion and cause on-off vibration with the limiting portion, the on-off vibration does not affect the conduction of the conductor slider to the upper and lower conductor portions, so that there will be no frequent on-off of the circuit current and no disturbance to the circuit, thereby improving the switching-on operation level. It is precisely because the rapid movement of the conductor slider will not cause frequent on-off of the circuit, so a greater acting force can be applied to the conductor slider through the driving mechanism to increase the movement speed of the conductor slider, thereby shortening the switching-on response time.

[0021] The present invention will be further described below through embodiments: Embodiment 1

[0022] As Figure 1 shown, the on-off mechanism of the present quick switch includes a first guide plate 1 and a second guide plate 2 which are oppositely arranged and parallel to each other. Both are flat plates. The first guide plate 1 is formed by connecting an insulating material part 101 and a conductor material part 102. The second guide plate 2 is formed by connecting an insulating material part 201 and a conductor material part 202. The conductor material part 102 is connected to the circuit incoming line end 3, and the conductor material part 202 is connected to the circuit outgoing line end 4. There is an insulating distance between the conductor material part 102 and the conductor material part 202. A conductor slider 5 is provided between the first guide plate 1 and the second guide plate 2. The conductor slider 5 can slide freely between the first guide plate 1 and the second guide plate 2. When the conductor slider 5 slides from the insulating material parts of the two guide plates to the conductor material parts, the incoming line end 3 and the outgoing line end 4 are conducted, that is, the closing operation is completed. When the conductor slider 5 moves from the conductor material part to the insulating material part, the circuit between the incoming line end 3 and the outgoing line end 4 is cut off and no longer conducted. In order to keep the conductor slider 5 moving directionally between the first guide plate 1 and the second guide plate 2, guide edges 103 can be extended downward on both sides of the first guide plate, and guide edges 203 can be extended upward on the second guide plate 2. The conductor slider 5 moves directionally under the guidance of the guide edges 103 and the guide edges 203. In addition to setting the guide edges, additional guide plates can also be provided on both sides of the first guide plate 1 and the second guide plate 2 to limit the conductor slider so that it remains moving between the first guide plate and the second guide plate. Guide rods can also be provided, and the conductor slider 5 is passed through the guide rods to limit the movement direction of the conductor slider through the guide rods.

[0023] Or as Figure 2As shown in the figure, both the first guide plate 1 and the second guide plate 2 are arc-shaped guide plates, and both are also formed by connecting an insulating material part and a conductor material part. For example, they can be two pairs of side surfaces of a cylinder, and the conductor slider 5 can be a cylinder. In order to reduce the arcing when contacting the first and second guide plates during movement, insulating jackets can be installed on both sides of the conductor slider 5 along the movement direction.

[0024] A limiting part is provided on one side of the conductor material part 102 of the first guide plate and the conductor material part 202 of the second guide plate, which is used to block the movement of the conductor slider 5. The limiting part can be a limiting plate or a limiting block. When driving devices are installed on both sides of this on-off mechanism, the housing of the driving device can be used as the limiting part. After installing the driving device, a quick switch is formed. Figure 1 In the figure, the boxes 6 on both sides are the first driving mechanism, and the box 7 is the second driving mechanism, which are respectively arranged on both sides of the first guide plate and the second guide plate. The front side wall of the box can block the movement of the conductor slider and serve as the limiting part. In this embodiment, both the first driving mechanism and the second driving mechanism select spring ejection mechanisms. The conductor slider is quickly ejected by the spring, so that it moves from the insulating material part 102 to the conductor material part 103, or the spring ejection mechanism on the other side springs the conductor slider 5 to the insulating material part, thereby cutting off the circuit.

[0025] Figure 3 The second embodiment of the on-off mechanism of the quick switch shown in the figure is to set the first guide rail 106 and the second guide rail 206 that are parallel to each other. Guide grooves 501 are opened on both sides of the conductor slider, and the guide grooves 501 are stuck on the first guide rail 106 and the second guide rail 206. The first guide rail 106 and the second guide rail 206 are also formed by connecting an insulating material and a conductor material. In this way, the conductor slider can move quickly between the two guide rails, thereby closing or cutting off the circuit.

[0026] Figure 4 The figure is a schematic diagram of the third embodiment, that is, the first guide rod 107 and the second guide rod 207 that are parallel to each other are set. A pair of through holes 502 are provided on the conductor slider, and the conductor slider is threaded on the first guide rod 107 and the second guide rod 207 through the through holes 502. The first guide rod and the second guide rod are also formed by connecting an insulating material and a conductor material. The conductor slider moves on the guide rod, and the circuit can be connected or cut off. In order not to affect the movement of the conductor slider, the conducting material parts of the first guide rod and the second guide rod should be connected to the wire from the side.

[0027] In addition to using the spring ejection mechanism, the first driving mechanism can also use an electromagnetic driving mechanism. At this time, a magnetic field is generated by the electromagnetic coil to attract the conductor slider and make it move. In order to enhance the magnetism of the conductor slider, a copper core can be made in the middle of the conductor slider, and iron plates or permanent magnets can be installed on both sides to enhance the attraction of the electromagnetic driving device by using ferromagnetism.

[0028] The above-mentioned first and second guide plates, first and second guide rails, and first and second guide rods are all guiding parts for making the conductor slider move in a certain direction. The setting of the insulating material part is to make it smoother when the conductor slider quickly enters the conducting material part. If only the conductor material part is set without the insulating material part, it is inevitable that the conductor slider will collide at the entrance of the conductor material, hindering the movement of the conductor slider and slowing down its movement speed, thus unable to meet the requirement of quick switching. The limiting part is to intercept the movement of the conductor slider and make it stop. Its material should be impact-resistant and preferably have a certain buffering property. In this way, after the conductor chute collides at a very high speed, it can be stopped without rebounding and separating from the upper and lower conductor material parts, so that the circuit will not be frequently switched on and off, thus overcoming the deficiencies of the previous circuit breakers.

[0029] The above embodiments are only illustrative of the concept and implementation of the present invention, and do not limit it. Under the concept of the present utility model, technical solutions without substantial transformation are still within the scope of protection.
