Description

Technical Field

[0001] This utility model relates to the field of intelligent composite switches, specifically an intelligent composite switch. Background Technology

[0002] Intelligent composite switches are intelligent electromechanical devices used for reactive power compensation in low-voltage power systems. They combine thyristor and magnetic latching relay technology to achieve precise capacitor switching and are widely used in industrial power distribution networks to improve power efficiency.

[0003] For example, the utility model with announcement number CN214674365U discloses a composite switch, which involves a switch body, a wire pressing base, a wire pressing block, a positioning part, a positioning groove, a fixing rod, and a fourth sliding groove. The wire pressing base is located near the wire in the switch body. The wire pressing block inside can be moved to press the wire, thereby fixing the wire. The positioning part is then inserted into the positioning groove, and the fixing rod is inserted into the fourth sliding groove to fix the wire pressing block, thereby preventing the wire from detaching from the switch body.

[0004] Regarding the above solution: The inventor believes that after the pressure block in the above reference document presses down on the wire of the composite switch, it is simply moved into the slot to fix the pressure block. Not only is the fixation not secure, but the pressure block also fails to effectively position the wire. Utility Model Content

[0005] To overcome the shortcomings of existing technology, after the wire pressing block presses down on the wire of the composite switch, it is simply moved into the groove to fix the wire pressing block. This not only results in an unstable fixation, but also prevents the wire pressing block from effectively positioning the wire. This utility model proposes an intelligent composite switch.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an intelligent composite switch, including an intelligent composite switch, wherein an electric wire is fixedly connected to the top of the intelligent composite switch, and a positioning mechanism is provided on the outside of the electric wire;

[0007] The positioning mechanism includes a frame located at the top of the intelligent composite switch. A first hollow block is fixedly connected to the inner cavity of the frame. A bidirectional threaded rod is rotatably connected to the inner cavity of the first hollow block. A first clamping rod and a second clamping rod are threadedly connected to the surface of the bidirectional threaded rod. A limit rod is fixedly connected to the inner cavity of the frame. The first clamping rod and the second clamping rod are both slidably connected to the surface of the limit rod. A first pressure block is slidably connected to one side of the first clamping rod, and a second pressure block is slidably connected to the side of the second clamping rod closest to the first clamping rod.

[0008] Preferably, a first hollow groove is provided on one side of the first clamping rod, a magnet strip is fixedly connected to the inner cavity of the first hollow groove, a magnet block is provided on one side of the magnet strip, and the magnet block is fixedly connected to one side of the first pressure block.

[0009] Preferably, a rotating groove is provided on one side of the frame, and a rotating rod is rotatably connected to the inner cavity of the rotating groove. One side of the rotating rod is fixedly connected to one side of a bidirectional threaded rod.

[0010] Preferably, the inner cavity of the frame is provided with a second hollow groove, and a limiting ring block is rotatably connected to the inner cavity of the second hollow groove. The limiting ring block is fixedly connected to the surface of the rotating rod.

[0011] Preferably, a second hollow block is fixedly connected to one side of the frame, and a threaded groove is provided on the top of the intelligent composite switch. The inner cavity of the second hollow block and the threaded groove is threadedly connected with a bolt.

[0012] Preferably, a connecting block is fixedly connected to the top of both the first and second pressure blocks, and a plurality of connecting blocks are provided.

[0013] Preferably, a first rubber pad is fixedly connected to the inner cavity of the first pressure block, and a second rubber pad is fixedly connected to the inner cavity of the second pressure block.

[0014] Preferably, a cover plate is provided on the top of the first hollow block, and the cover plate is fixedly connected to the top of the frame.

[0015] The advantages of this utility model are:

[0016] 1. In this device, the positioning mechanism can be installed on the outside of the wire. Rotating the bidirectional threaded rod drives the first clamping rod and the second clamping rod to move in opposite directions. The first clamping rod and the second clamping rod will then drive the first pressure block and the second pressure block to move towards each other, thereby clamping and positioning the wire. This prevents the wire from being pulled or vibrated by external forces and thus from coming off the intelligent composite switch. Furthermore, the threaded connection between the bidirectional threaded rod and the first clamping rod and the second clamping rod has a certain degree of self-locking, which can effectively fix the first pressure block and the second pressure block to prevent movement, thereby achieving a better positioning effect for the wire.

[0017] 2. In this device, the first and second wire pressing blocks can be moved laterally to accommodate multiple wires with different spacings. At the same time, the first and second wire pressing blocks will also drive the magnet block to slide on one side of the magnet strip. Through the magnetic attraction between the magnet strip and the magnet block, the first and second wire pressing blocks can be stabilized after they move. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0028] This application discloses an intelligent composite switch. (Refer to...) Figure 1-4A smart composite switch includes a smart composite switch 1, with a wire 2 fixedly connected to the top of the smart composite switch 1. A positioning mechanism 3 is provided on the outside of the wire 2. The smart composite switch 1 can be connected to other parts inside the distribution box through the wire 2, while the positioning mechanism 3 can position the wire 2 to prevent the wire 2 from detaching from the smart composite switch 1.

[0029] The positioning mechanism 3 includes a frame 31, which is located on top of the intelligent composite switch 1. A first hollow block 32 is fixedly connected to the inner cavity of the frame 31. A bidirectional threaded rod 33 is rotatably connected to the inner cavity of the first hollow block 32. A first clamping rod 34 and a second clamping rod 35 are threadedly connected to the surface of the bidirectional threaded rod 33. A limit rod 36 is fixedly connected to the inner cavity of the frame 31. The first clamping rod 34 and the second clamping rod 35 are both slidably connected to the surface of the limit rod 36. A first pressure block 37 is slidably connected to one side of the first clamping rod 34. A second pressure block 38 is slidably connected to the side of the second clamping rod 35 near the first clamping rod 34.

[0030] The frame 31 is installed on the outside of the wire 2 and can be connected to the bidirectional threaded rod 33 through the first hollow block 32, allowing the bidirectional threaded rod 33 to rotate. The threads on both sides of the bidirectional threaded rod 33 are opposite, and when rotated, they can drive the first clamping rod 34 and the second clamping rod 35 to move in opposite directions respectively. The limiting rod 36 is located on the side of the first clamping rod 34 and the second clamping rod 35 away from the bidirectional threaded rod 33, and can limit the first clamping rod 34 and the second clamping rod 35, so that the first clamping rod 34 and the second clamping rod 35 can move smoothly when the bidirectional threaded rod 33 rotates. The first and second wire pressing blocks 37 and 38 have arc-shaped grooves, which can be driven by the first clamping rod 34 and the second clamping rod 35 to move in opposite directions. After moving, they press down on the wire 2, so that the wire 2 can be positioned and cannot be pulled or vibrated by external force to detach from the intelligent composite switch 1. At the same time, the connection between the bidirectional threaded rod 33 and the first clamping rod 34 and the second clamping rod 35 has a certain self-locking property, which makes the first and second wire pressing blocks 37 and 38 more stable and not easy to move, thus effectively positioning the wire 2.

[0031] Reference Figure 4A first hollow groove 41 is provided on one side of the first clamping rod 34. A magnetic strip 42 is fixedly connected to the inner cavity of the first hollow groove 41. A magnetic block 43 is provided on one side of the magnetic strip 42. The magnetic block 43 is fixedly connected to one side of the first wire pressing block 37. The magnetic strip 42 can be connected inside the first hollow groove 41, while the magnetic block 43 is connected to the first wire pressing block 37 and magnetically attracted to the magnetic strip 42. This allows the first wire pressing block 37 to move on one side of the magnetic strip 42 via the magnetic block 43, thereby adjusting the spacing between multiple sets of first wire pressing blocks 37 and second wire pressing blocks 38 to accommodate multiple wires 2 with different spacings, thus improving the range of applications. Furthermore, due to the magnetic attraction between the magnetic strip 42 and the magnetic block 43, the first wire pressing block 37 can remain stable after movement. The second wire pressing block 38 also has a first hollow groove 41, a magnetic strip 42, and a magnetic block 43 on one side, achieving the same effect.

[0032] Reference Figure 5 A rotating groove 51 is provided on one side of the frame 31. A rotating rod 52 is rotatably connected to the inner cavity of the rotating groove 51. One side of the rotating rod 52 is fixedly connected to one side of the bidirectional threaded rod 33. The rotating rod 52 can be placed inside the rotating groove 51 so that the rotating rod 52 can be connected to the bidirectional threaded rod 33, thereby facilitating the rotation of the bidirectional threaded rod 33 by the operator.

[0033] Reference Figure 5 The inner cavity of the frame 31 is provided with a second hollow groove 61. The inner cavity of the second hollow groove 61 is rotatably connected to a limiting ring block 62. The limiting ring block 62 is fixedly connected to the surface of the rotating rod 52. The second hollow groove 61 can limit the rotating rod 52 and the bidirectional threaded rod 33 through the limiting ring block 62, so that the bidirectional threaded rod 33 is not easy to move inside the frame 31. In turn, the first clamping rod 34 and the second clamping rod 35, as well as the first wire pressing block 37 and the second wire pressing block 38 are also not easy to move, making the positioning of the wire 2 more stable.

[0034] Reference Figure 6 A second hollow block 71 is fixedly connected to one side of the frame 31. A threaded groove 72 is provided on the top of the intelligent composite switch 1. Bolts 73 are threadedly connected to the inner cavities of the second hollow block 71 and the threaded groove 72. The bolts 73 can be connected to the interior of the second hollow block 71 and the threaded groove 72 to achieve the effect of fixing the frame 31. At the same time, the bolts 73 can also be rotated out of the threaded groove 72 and the bolts 73, which facilitates the disassembly of the frame 31. This allows the frame 31 to be reused on different intelligent composite switches 1, reducing waste.

[0035] Reference Figure 3The top of the first pressure block 37 and the second pressure block 38 are fixedly connected to a connecting block 8. Several connecting blocks 8 are provided. The connecting blocks 8 make it easier for the staff to move the first pressure block 37 and the second pressure block 38. They only need to push the connecting block 8.

[0036] Reference Figure 3 The inner cavity of the first pressure block 37 is fixedly connected to a first rubber pad 91, and the inner cavity of the second pressure block 38 is fixedly connected to a second rubber pad 92. The first rubber pad 91 and the second rubber pad 92 can replace the first pressure block 37 and the second pressure block 38 to clamp the wire 2, which not only makes it less likely to damage the wire 2, but also further improves stability due to excessive friction.

[0037] Reference Figure 5 The top of the first hollow block 32 is provided with a cover plate 10, which is fixedly connected to the top of the frame 31. The cover plate 10 can block the bidirectional threaded rod 33, so that dust will not fall onto the surface of the bidirectional threaded rod 33, thus making the bidirectional threaded rod 33 less likely to be blocked by dust.

[0038] Working principle: When using this device, firstly, install the frame 31 on the surface of the intelligent composite switch 1 at the position where the wire 2 needs to be connected. Then, the operator connects the wire 2 to the intelligent composite switch 1. Next, slide the first wire pressing block 37 and the second wire pressing block 38 onto the surface of the wire 2. At the same time, the first wire pressing block 37 and the second wire pressing block 38 will drive the magnet block 43 to move on one side of the magnet strip 42, and stabilize it through the magnetic attraction between the magnet block 43 and the magnet strip 42. Then, rotate the rotating rod 52 to drive the bidirectional threaded rod 33 to rotate. The bidirectional threaded rod 33 will drive the first clamping rod 34 and the second clamping rod 35 to move in opposite directions. At the same time, the first clamping rod 34 and the second clamping rod 35 will slide on the surface of the limiting rod 36. After that, the first clamping rod 34 and the second clamping rod 35 will slide on the surface of the limiting rod 36. The second clamping rod 35 will also drive the first clamping block 37 and the second clamping block 38 to move in opposite directions, thereby clamping the wire 2 and positioning the wire 2 so that it cannot be pulled or vibrated out of the intelligent composite switch 1. At the same time, the threaded connection between the bidirectional threaded rod 33 and the first clamping rod 34 and the second clamping rod 35 has a certain self-locking property, which can effectively fix the first clamping block 37 and the second clamping block 38 to prevent movement, thereby better positioning the wire 2. This solves the problem that after the clamping block presses down on the wire 2 of the intelligent composite switch 1, simply moving the block into the slot to fix it is not only not secure, but also makes the clamping block unable to effectively position the wire 2.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
