Description

Technical Field

[0001] The invention belongs to the technical field of switches, and in particular relates to a switch with a lamp and an arc control function. Background Art

[0002] Generally, in circuits with high voltage and high current, circuit breakers with arc extinguishing function are often used to control the opening and closing of the circuit. Ordinary switches do not have arc extinguishing function. If an arc extinguishing structure is added to an ordinary switch, the volume of the switch will be much larger than that of the ordinary switch.

[0003] At present, in some circuits with slightly larger currents, there is no circuit breaker configuration. In this case, the dynamic and static electric shocks of ordinary switches in the circuit will produce weak arcs. Although there is no danger, the arc erosion of the contacts affects the life of the contacts. In order to solve this problem, while trying to use the components of the original switch, that is, using the processing production line of the original switch, it is necessary to design an arc control mechanism that can be added to the ordinary switch.

[0022] As a preferred solution, an electric wire is connected between the battery and the motor, and the air pump is fixedly connected to the output shaft of the motor.

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] 1. In a conventional switch, when the connecting plate at the main control switch is squeezed and swung for opening and closing control, the pressure column squeezing the connecting plate will slide from one side of the connecting plate to the other side as the main control switch swings, thereby controlling whether the connecting plate is connected to the corresponding contact. However, in a conventional switch, when the pressure column slides, the time required for the connecting plate to close and separate from the contact is relatively long. The longer the time, the easier it is to generate an arc, and the arc generation time is also correspondingly longer. In order to solve this problem, the present invention provides a limit assembly on the side of the connecting electrode. When the main control switch swings, the main control switch drives the arc bar to swing through the guide rod. During the swinging process, the arc bar always contacts and cooperates with the arc surface on the driving block in an extrusion manner, and the connecting electrode deforms and stores energy until the arc bar is completely separated from the driving block. The extrusion of the arc bar on the driving block will disappear, and then the connecting electrode will quickly swing open under the action of its own deformation and the action of the pressure column, that is, the connecting electrode and the contact will be disconnected. Because the arc bar limits the driving block when the main control switch starts to swing, the connecting electrode is limited and cannot swing relative to the contact, and it is quickly disconnected after the limit is released. Therefore, the time for the connecting electrode to be disconnected from the contact is reduced to a certain extent, that is, the time for the arc to be generated during the disconnection process of the connecting electrode and the contact is reduced, the amount of arc generated is reduced, and the contact and the connecting electrode are protected.

[0025] 2. When the air pump is working, the air pump will pump air into the second connecting air pipe, and the pumping of air into the second connecting air pipe will form a negative pressure in the fourth connecting air pipe connected thereto, and the third valve plug will open. When the contacts at the socket control switch and the connecting electrode are opened and closed, an arc will be generated. After the arc is generated, it will be sucked into the fourth connecting air pipe by the air pump. When the arc enters the fourth connecting air pipe, part of the heat will be absorbed by the heat-absorbing wire mesh when passing through the heat-absorbing wire mesh, and the remaining heat will be absorbed and discharged by the air pump through the second connecting air pipe; that is, the degree of ablation of the connecting electrode and contacts at the socket control switch due to the arc generated at that location is reduced to a certain extent.

[0026] 3. When an arc is generated at the main control switch, the first valve plug and the second valve plug are opened due to the air pump working to exhaust air. The gas generated by the arc will enter from the third air hole under the action of the air pump. The entering gas pushes the sealing slide to open the sealing slide. The gas generated by the arc enters the sliding cavity from the third air hole. The gas entering the sliding cavity passes through the second air hole and the first air hole and enters the installation cavity. The gas entering the installation cavity will first absorb heat by the heat-absorbing wire mesh installed in the installation cavity, and then be sucked into the air pump and discharged. When the amount of gas is relatively large, the first valve plug and the second valve plug are closed, and the gas entering the installation cavity will squeeze the sealing plate to open the sealing plate. At this time, the installation cavity, the second connecting air pipe and the elliptical shell form a gas flow channel, and the outside gas enters from the exhaust port to dissipate the heat of the gas generated by the arc. Then the gas is discharged from the exhaust hole opened on the elliptical shell.

[0027] 4. In the present invention, since the current at the main control switch is relatively large, a double arc control is provided at the main control switch.

[0028] 5. The present invention can limit the indicator light group through the limit screw, and fix the indicator light group between the indicator light back cover and the indicator light front cover; when the indicator light group needs to be replaced, it is only necessary to unscrew the limit screw, release the limit screw on the indicator light group, and then the indicator light group can be quickly taken out; the indicator light module of the present invention indicates the on and off indicator light is closed and has high safety.

[0051] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples or drawings are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0052] A switch with a light and arc control function, such as Figure 1 , 2 As shown, it includes a switch panel 1, a bolt hole 2, a main control switch 3, a socket control switch 4, a socket 5, an indicator light module 6, a wiring port 8, and a rear panel 12. Figure 2 As shown, the air pump 15, the battery 16, the motor 17 and the arc control assembly 10 are fixedly mounted on the rear panel 12. Figure 3 As shown, an electric wire is connected between the battery 16 and the motor 17, and the air pump 15 is fixedly connected to the output shaft of the motor 17; Figure 4 As shown, the arc control assembly 10 includes an elliptical housing 13, a second connecting air pipe 18, a first valve plug 19, a first spring 20, a third connecting air pipe 21, a second valve plug 22, a second spring 23, a baffle 24, an exhaust hole 25, a connecting rod 26, and a pull rod 27, wherein as shown in Figure 3As shown, one end of the second connecting air pipe 18 is fixedly mounted on the output end of the air pump 15. Figure 4 As shown, a first valve plug 19 is slidably installed in the second connecting air pipe 18, and a first spring 20 is installed between the first valve plug 19 and the second connecting air pipe 18; one end of the elliptical shell 13 is fixedly installed on the second connecting air pipe 18, and the other end of the elliptical shell 13 is fixedly installed with a third connecting air pipe 21, and one end of the third connecting air pipe 21 extends into the inner side of the elliptical shell 13; a second valve plug 22 is slidably installed in the third connecting air pipe 21, and a second spring 23 is installed between the second valve plug 22 and the third connecting air pipe 21; a plurality of exhaust holes 25 are uniformly opened on the outer wall surface of the elliptical shell 13 near one end of the third connecting air pipe 21, and the outer surface of each exhaust hole 25 is A baffle 24 is slidably installed on each side, and the baffle 24 is close to the outer wall of the elliptical shell 13. A connecting rod 26 is swingably installed on the outer wall of each baffle 24. The end of the connecting rod 26 away from the baffle 24 is connected to the second valve plug 22 through a pull rod 27. The connecting rod 26 is hingedly connected to the pull rod 27, and the pull rod 27 is fixedly connected to the second valve plug 22; when the second connecting air pipe 18 and the third connecting air pipe 21 are in an open state, the exhaust hole 25 is blocked by the corresponding baffle 24 and is in a closed state; a plurality of fourth air holes 60 are evenly opened on the side of the second connecting air pipe 18 close to the second valve plug 22, and a plurality of ribs 14 are evenly installed on the elliptical shell 13. In the present invention, when the second valve plug 22 slides relative to the third connecting air pipe 21 toward the second connecting air pipe 18, the second valve plug 22 will drive the pull rod 27 to slide, and the sliding of the pull rod 27 drives the connecting rod 26 to swing, and the connecting rod 26 drives the baffle 24 to slide on the outer wall of the elliptical shell 13, so that the exhaust hole 25 opened on the elliptical shell 13 is opened. When the amount of gas sucked into the second connecting air pipe 18 is relatively large, the second valve plug 22 and the first valve plug 19 will be closed, and the gas sucked into the second connecting air pipe 18 directly enters the elliptical shell 13 from the fourth air hole 60. Because the inner cavity of the elliptical shell 13 is large, the heat dissipation efficiency of the gas entering can be improved to a certain extent; at this time, the exhaust hole 25 is open, and the gas entering the elliptical shell 13 is directly discharged from the exhaust hole 25.

[0053] like Figure 5 , 6 As shown, a circular hole is opened at the contact area of ​​the socket control switch 4, and the circular hole passes through the rear panel 12; a heat dissipation component 11 is fixedly installed at the circular hole, and the heat dissipation component 11 includes a fourth connecting air pipe 32, a third valve plug 29, and a third spring 28, wherein the fourth connecting air pipe 32 is fixedly installed at the circular hole, as shown in FIG. Figure 7As shown, a plurality of second ribs 58 are evenly fixedly installed on the outer circumferential surface of the fourth connecting air pipe 32; a third valve plug 29 is slidably installed in the fourth connecting air pipe 32, and a third spring 28 is installed between the third valve plug 29 and the fourth connecting air pipe 32; a heat absorbing wire mesh 30 is installed in the fourth connecting air pipe 32 and the circular hole; the fourth connecting air pipe 32 is connected to the second connecting air pipe 18 through the air pipe. The function of the second ribs 58 is to improve the heat dissipation efficiency of the fourth connecting air pipe 32. The function of the heat absorbing wire mesh 30 is to improve the heat dissipation efficiency of the heat in the fourth connecting air pipe 32. When the air pump 15 is working, the air pump 15 will pump air into the second connecting air pipe 18. The pumping of air from the second connecting air pipe 18 will form a negative pressure in the fourth connecting air pipe 32 connected thereto, and the third valve plug 29 will open. When the contacts at the socket control switch 4 are opened and closed with the connecting electrode 35, an arc will be generated. After the arc is generated, it will be sucked into the fourth connecting air pipe 32 by the air pump 15. When the arc enters the fourth connecting air pipe 32, part of the heat will be absorbed by the heat absorbing wire mesh 30 when passing through the heat absorbing wire mesh 30, and the remaining heat will be absorbed and discharged by the air pump 15 through the second connecting air pipe 18; that is, the degree of ablation of the connecting electrode 35 and the contacts at the socket control switch 4 due to the arc generated at that place is reduced to a certain extent.

[0054] like Figure 2 , 8 As shown, an arc control block 33 is installed at the contact area of ​​the main control switch 3, and a uniformly distributed first rib 48 is installed on the upper end of the arc control block 33; Figure 2 As shown, the rear panel 12 is provided with a vent 7 corresponding to the arc control block 33; Fig.12 As shown, a first connecting air pipe 9 is fixedly installed at one end of the arc control block 33; the inner side of the arc control block 33 is divided into an installation cavity 53 and a sliding cavity 57; a heat absorbing screen 30 is installed in the installation cavity 53, an exhaust port 51 is opened on one side of the installation cavity 53, a sealing plate 50 is slidably installed on the side of the arc control block 33 with the exhaust port 51, and a fifth spring 49 is installed between the sealing plate 50 and the arc control block 33; a plurality of guide slide bars 52 are evenly installed in the sliding cavity 57, a second air hole 55 evenly distributed is opened on the sealing slide plate 47, the sealing slide plate 47 is slidably installed in the installation cavity 53 through the guide slide bar 52, and a sixth spring 56 is installed between the sealing slide plate 47 and the bottom surface of the sliding cavity 57; a third air hole 59 evenly distributed is opened on the bottom surface of the sliding cavity 57, and a first air hole 54 evenly distributed is opened on the partition between the installation cavity 53 and the sliding cavity 57, and the first air hole 54 and the second air hole 55 are aligned; as shown Fig.13As shown, the third air hole 59 is staggered with the first air hole 54 and the second air hole 55; the first connecting air pipe 9 passes through the rear panel 12 and is connected to the third connecting air pipe 21 through the air pipe. The function of the heat absorbing wire mesh 30 is to improve the heat dissipation efficiency of the heat entering the installation cavity 53. The function of the first rib 48 is to improve the heat dissipation efficiency of the arc control block 33.

[0055] In the present invention, when the sealing slide 47 moves to be close to the bottom surface of the sliding cavity 57, the sealing slide 47 will seal the third air hole 59 opened on the lower side of the sliding cavity 57. When there is a gap between the sealing slide 47 and the sliding cavity 57, the second air hole 55 opened on the sealing slide 47 can ensure that the upper and lower cavities of the sealing slide 47 in the sliding cavity 57 are connected. The function of the first air hole 54 is to ensure that the sliding cavity 57 is connected to the installation cavity 53.

[0056] like Fig. 9 , 10 As shown, a limit assembly 36 is installed at the connecting electrode 35 on one side of the main switch 3, and the limit assembly 36 includes a guide rod 42, an arc strip 41, a fourth spring 43, a transmission block 37, and a driving block 39, wherein a guide rod 42 is slidably installed on the side wall of the main switch 3, an L-shaped arc strip 41 is fixedly installed on the guide rod 42, and a fourth spring 43 is installed between the guide rod 42 and the side wall of the main switch 3; the swingable connecting electrode 35 at the main switch 3 A transmission block 37 is fixedly installed on the side wall, a guide block 40 is fixedly installed on one side of the driving block 39, and the driving block 39 is slidably installed on the terminal 34 on the corresponding side through the guide block 40. The upper end of the driving block 39 is provided with an arc surface 44, one side of the driving block 39 has a first inclined surface 45 from top to bottom, and the other side has a second inclined surface 46 distributed front to back; the arc strip 41 cooperates with the driving block 39; a clamping block 38 is fixedly installed on the driving block 39, and the clamping block 38 is clamped with the transmission block 37.

[0057] In a conventional switch, when the connecting plate 35 at the main control switch 3 is squeezed and swung for opening and closing control, the pressure column squeezing the connecting plate 35 will slide from one side of the connecting plate 35 to the other side as the main control switch 3 swings, thereby controlling whether the connecting plate 35 is connected to the corresponding contact. However, in a conventional switch, when the pressure column slides, the time required for the connecting plate 35 to close and separate from the contact is relatively long, and the longer the time, the easier it is to generate an arc, and the arc generation time is also correspondingly longer. In order to solve this problem, the present invention provides a limit assembly 36 on the side of the connecting electrode 35. When the main switch 3 swings, the main switch 3 drives the arc strip 41 to swing through the guide rod 42. During the swinging process, the arc strip 41 is always pressed and contacted with the arc surface 44 on the driving block 39, and the connecting electrode 35 deforms and stores energy until the arc strip 41 is completely separated from the driving block 39. The pressing of the arc strip 41 on the driving block 39 will disappear. After that, the connecting electrode 35 will quickly swing open under the action of its own deformation and the action of the pressure column, that is, the connecting electrode 35 and the contact will be disconnected. Because the arc strip 41 limits the driving block 39 when the main switch 3 starts to swing, the connecting electrode 35 is limited and cannot swing relative to the contact, and it is quickly disconnected after the limit is released. Therefore, the time for the connecting electrode 35 to be disconnected from the contact is reduced to a certain extent, that is, the time for the arc to be generated during the disconnection process between the connecting electrode 35 and the contact is reduced, the amount of arc generated is reduced, and the contact and the connecting electrode 35 are protected.

[0058] When the main switch 3 is closed, the main switch 3 will drive the arc bar 41 to swing, and the end of the arc bar 41 that contacts the driving block 39 will move laterally relative to the main switch 3 under the action of the first inclined surface 45 on the driving block 39, and the fourth spring 43 is compressed; when the arc bar 41 moves to cooperate with the second inclined surface 46, under the joint action of the second inclined surface 46 and the swing of the main switch 3, the arc bar 41 moves upward relative to the driving block 39, and finally moves to the uppermost side of the driving block 39. At this time, under the action of the fourth spring 43, the arc bar 41 moves laterally in the opposite direction to a position cooperating with the arc surface 44, that is, the limit assembly 36 designed in the present invention will not affect the normal opening and closing of the main switch 3.

[0059] In the present invention, since the current at the main control switch 3 is relatively large, a double arc control is provided at the main control switch 3 .

[0062] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.

[0063] Implementation method: When the switch designed by the present invention is used, when an arc is generated at the main control switch 3, the air pump 15 works to pump air, the first valve plug 19 and the second valve plug 22 are opened, and the gas generated by the arc enters from the third air hole 59 under the action of the air pump 15. The entering gas pushes the sealing slide 47, so that the sealing slide 47 opens, and the gas generated by the arc enters the sliding cavity 57 from the third air hole 59. The gas entering the sliding cavity 57 enters the installation cavity 53 through the second air hole 55 and the first air hole 54. The gas entering the installation cavity 53 is The gas will first absorb heat through the heat-absorbing mesh 30 installed in the installation cavity 53, and then be sucked into the air pump 15 and discharged; when the amount of gas is relatively large, the first valve plug 19 and the second valve plug 22 are closed, and the gas entering the installation cavity 53 will squeeze the sealing plate 50, causing the sealing plate 50 to open. At this time, the installation cavity 53, the second connecting air pipe 18 and the elliptical shell 13 form a gas flow channel, and external gas enters from the exhaust port 51 to dissipate the heat of the gas generated by the arc, and then the gas is discharged from the exhaust hole 25 opened on the elliptical shell 13.

[0064] When the contacts at the socket control switch 4 are opened and closed with the connecting electrode 35, an arc will be generated. After the arc is generated, it will be sucked into the fourth connecting air pipe 32 by the air pump 15. When the arc enters the fourth connecting air pipe 32, part of the heat will be absorbed by the heat-absorbing wire mesh 30 when passing through the heat-absorbing wire mesh 30, and the remaining heat will be absorbed and discharged by the air pump 15 through the second connecting air pipe 18; that is, the degree of ablation of the connecting electrode 35 and the contacts at the socket control switch 4 due to the arc generated at that place is reduced to a certain extent.
