Description

Technical Field

[0001] This invention relates to the field of high-voltage electrical appliance manufacturing technology, specifically a conductor structure that can accommodate multiple currents. Background Technology

[0002] The primary terminals connecting high-voltage electrical appliances to the busbar are a crucial component of a power system. Their primary function is to ensure the stable operation of the power system and effectively protect it from damage. Primary terminals are typically made of materials with excellent electrical conductivity, such as copper or aluminum, to efficiently transmit power. Their design and structure are also critical, requiring them to withstand the voltage and current of the power system.

[0003] The dimensions of primary terminals connecting high-voltage electrical appliances to the busbar are influenced by factors such as rated primary current, mechanical force, conductor connection structure, and the specific needs of users, resulting in a wide variety of specifications. Currently, the industry typically manufactures terminals using casting, with almost every specification requiring its own independent mold. Mold costs are very high, and the production cycle is long, necessitating a new solution.

The nut and the threaded post are located on both sides of the combined plate, and a nut is screwed onto the outer side of the threaded post.

[0010] Preferably, the bottom plate has multiple composite plates on its top, and each composite plate has a clamp fixedly installed on its top, with adjacent clamps fitting together.

The trapezoidal plug is an inverted trapezoid, and the bottom of the trapezoidal plug is in contact with the top of the combined rod.

[0012] Preferably, the clamp has two connecting grooves and a circular groove inside. The sliding groove is connected to the circular groove through the corresponding connecting groove. The circular groove penetrates both sides of the clamp. A baffle is fixedly installed inside the circular groove. The baffle divides the inside of the circular groove into an insertion groove and a sliding groove. The sliding groove is connected to the connecting groove.

[0017] Beneficial effects

[0018] This invention provides a conductor structure capable of handling multiple currents. Compared with the prior art, it has the following advantages:

[0019] Beneficial effects:

[0020] 1. This conductor structure can meet multiple current requirements. By aligning the combination rod with the hole opened on the combination plate and inserting it, the combination rod will completely penetrate the inside of the insert block. After penetration, it is fixed by screwing the nut onto the threaded post. After fixing, the internal structure is shown in the figure, thus completing the fixing of the combination plate and the clamp. Different numbers of clamps can be combined on the bottom plate as needed, so that the overall length of the clamp can be changed at will to suit the rated primary current of high voltage electrical appliances of different sizes.

[0021] 2. This conductor structure, capable of handling multiple currents, utilizes air entering the sliding groove to compress the internal piston block. As the piston block moves outward, it simultaneously moves the insertion rod outward, which, via the second limiting ring, is fixed. After the clamp is secured, the sliding groove inside the clamp aligns with the insertion slot inside the adjacent clamp, allowing the insertion rod to be inserted into the adjacent insertion slot as it moves outward. When fixing a single clamp using the combination rod, adjacent clamps can be assembled together using the insertion rod. When the assembled clamps secure the wire, they simultaneously compress the inner wire of each clamp, resulting in a better wire securing effect.

[0022] 3. This conductor structure can accommodate multiple currents. By rotating the outer terminal block, the terminal block rotates, which in turn drives the rotating shaft to rotate. The rotating shaft then drives the screw to rotate, thus fixing or releasing the fixing block. This allows for the disassembly and installation of the terminal block by rotating it. Terminal blocks of different sizes can be assembled using the fixing block, enabling the arbitrary combination of different sized terminal blocks according to the rated primary current of the high-voltage electrical appliances and the user's requirements.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0032] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Reference Figures 1 to 6 This application provides a conductor structure that can meet multiple current requirements, including a clamp 1 and a terminal block 5. A combination component 2 is provided at the bottom of the clamp 1, an auxiliary component 3 is provided inside the clamp 1, and a fixing component 4 is provided between the combination component 2 and the terminal block 5.

[0034] The combined component 2 includes a combined plate 21 and a bottom plate 22. The clamp 1 is fixedly installed on the top of the bottom plate 22. The top of the combined plate 21 is fixedly installed with a plug 27. The bottom of the bottom plate 22 has a slot 28. The plug 27 is inserted into the slot 28. A combined rod 24 is inserted into the bottom plate 22 and passes through the plug 27.

[0035] The fixing component 4 includes a fixing block 41 and a fixing groove 42. The fixing groove 42 is opened inside the bottom plate 22. The fixing block 41 is fixedly installed on the side of the wiring board 5 and is inserted into the fixing groove 42.

[0036] In an optional embodiment: a nut 23 is fixedly installed on one side of the combination rod 24, and a threaded post 25 is fixedly installed on the other side of the combination rod 24. The nut 23 and the threaded post 25 are located on both sides of the combination plate 21, and a nut 26 is screwed onto the outside of the threaded post 25.

[0037] It should be noted that during the assembly of clamp 1, the combination plate 21 and the bottom plate 22 are inserted into the slot 28 via the insert block 27 to pre-fix the clamp 1. When multiple clamps 1 are combined, adjacent clamps 1 fit tightly against each other. Then, the combination rod 24 is inserted by aligning it with the hole on the combination plate 21. After insertion, the combination rod 24 will completely penetrate the insert block 27. After penetration, it is fixed by screwing the nut 26 onto the threaded post 25. After fixing, the internal structure is as follows. Figure 3 As shown, this completes the fixing of the combination plate 21 and the clamp 1. As needed, different numbers of clamps 1 can be combined on the bottom plate 22, so that the overall length of the clamp 1 can be changed at will to suit the rated primary current of high voltage electrical appliances of different sizes.

[0038] In an optional embodiment: a plurality of combined plates 21 are provided on the top of the bottom plate 22, and a clamp 1 is fixedly installed on the top of each combined plate 21, with adjacent clamps 1 fitting together.

[0039] It should be noted that the tightly fitted clamps 1 after assembly make the wire fixing through the clamps 1 more stable and will not affect the power transmission of the clamps 1.

[0040] In an optional embodiment: the auxiliary component 3 includes a slide 31, which is opened inside the clamp 1. A trapezoidal plug 32 is slidably connected inside the slide 31. A spring 33 is fixedly installed between the top of the trapezoidal plug 32 and the inner top wall of the slide 31. The trapezoidal plug 32 is an inverted trapezoid, and the bottom of the trapezoidal plug 32 is in contact with the top of the combined rod 24.

[0041] It should be noted that when the combination rod 24 is not inserted, the trapezoidal plug 32 is located inside the insert block 27 under the action of the spring 33. When the combination rod 24 is inserted, the threaded post 25 on the combination rod 24 will first contact the trapezoidal plug 32. Under the action of the inclined side of the trapezoidal plug 32, the trapezoidal plug 32 will be squeezed upward. When the trapezoidal plug 32 is squeezed upward, the spring 33 is contracted. Since the trapezoidal plug 32 and the slide groove 31 are in a sealed state, when the trapezoidal plug 32 moves upward, the air above the slide groove 31 is compressed.

[0042] In an optional embodiment: the clamp 1 has two connecting grooves 34 and a circular groove 35 inside. The sliding groove 31 is connected to the circular groove 35 through the corresponding connecting groove 34. The circular groove 35 penetrates the two side walls of the clamp 1. A baffle 36 is fixedly installed inside the circular groove 35. The baffle 36 divides the inside of the circular groove 35 into an insertion groove and a sliding groove. The sliding groove is connected to the connecting groove 34.

[0043] It should be noted that when the trapezoidal plug 32 moves upward, the compressed air will enter the circular groove 35 through the connecting groove 34. The air entering the circular groove 35 will be blocked by the baffle 36 and enter the sliding groove.

[0044] In an optional embodiment: a first limiting ring 39 and a second limiting ring 310 are fixedly installed inside the sliding groove. The second limiting ring 310 is located at the outlet of the sliding groove, and the first limiting ring 39 is located at the connection between the sliding groove and the connecting groove 34. A piston block 37 is slidably connected between the first limiting ring 39 and the second limiting ring 310. A plug rod 38 is fixedly installed on the side of the piston block 37 and is inserted into the second limiting ring 310.

[0045] It should be noted that the air entering the sliding groove will compress the piston block 37 inside. As the piston block 37 moves outward, it will drive the insertion rod 38 to move outward synchronously and move outward through the second limiting ring 310. The second limiting ring 310 can restrict the piston block 37 to move out of the sliding groove without affecting the outward movement of the insertion rod 38. The first limiting ring 39 can restrict the other side of the piston block 37 and restrict the piston block 37 without affecting the air flow. After the clamp 1 is fixed, the sliding groove inside the clamp 1 will correspond to the insertion groove inside the adjacent clamp 1, so that when the insertion rod 38 moves outward, it can be inserted into the adjacent insertion groove. When a single clamp 1 is fixed by the combination rod 24, adjacent clamps 1 can be combined together by the insertion rod 38. When the combined clamp 1 is used to fix the wire, it can simultaneously compress the wire inside the clamp 1, thereby achieving a better wire fixing effect.

[0046] In an optional embodiment: the fixing block 41 has an internal groove 47 inside, and a locking block 43 is inserted into the inside of both sides of the internal groove 47. The locking block 43 is inserted into the bottom plate 22 on the corresponding side.

[0047] It should be noted that when the fixing block 41 is inserted into the fixing groove 42, the fixing block 41 is fixed by the locking block 43 inserted at the connection between the fixing block 41 and the fixing groove 42, thereby fixing the terminal block 5 and the bottom plate 22. When conducting electricity, the terminal block 5 is connected to the bottom plate 22, the bottom plate 22 is connected to the combination plate 21, and the combination plate 21 is connected to the clamp 1. The terminal block 5, the bottom plate 22, the combination plate 21 and the clamp 1 are all made of aluminum.

[0048] In an optional embodiment: a screw 44 is rotatably connected inside the internal groove 47, and two sliders 45 are screwed to the outside of the screw 44. A connecting rod 46 is hinged between each slider 45 and the corresponding locking block 43. The two sliders 45 are screwed to the outside of the two different thread directions of the screw 44, and the two sliders 45 are symmetrical about the center of the screw 44.

[0049] It should be noted that by rotating the screw 44, the two sliders 45 on it can be driven to move synchronously in opposite directions. The synchronous reverse movement of the sliders 45 can change the included angle of the two connecting rods 46 on the same locking block 43. After the included angle of the connecting rods 46 is changed, the locking block 43 will be moved. After the locking block 43 is moved out of the bottom plate 22, the fixing of the fixing block 41 can be released. Thus, by rotating the screw 44, the fixing effect between the fixing block 41 and the bottom plate 22 can be changed.

[0050] In an optional embodiment: a rotating shaft is fixedly installed on the outer end of the screw 44, the rotating shaft passing through the side wall of the fixing block 41 and being fixedly connected to the terminal block 5.

[0051] It should be noted that when the screw 44 needs to rotate, the outer terminal plate 5 is rotated. The rotation of the terminal plate 5 drives the rotating shaft to rotate, which in turn drives the screw 44 to rotate, thereby fixing or releasing the fixing block 41. This allows the terminal plate 5 to be disassembled and installed by rotating it. Terminal plates 5 of different sizes can be assembled using the fixing block 41, allowing for the arbitrary combination of different sizes of terminal plates 5 according to the rated primary current of the high-voltage electrical appliances and the user's requirements.

[0052] Working principle: During the assembly of clamp 1, the combination plate 21 and the bottom plate 22 are inserted into the slot 28 through the insert block 27 to pre-fix the clamp 1. When multiple clamps 1 are combined, adjacent clamps 1 fit tightly against each other. Then, the combination rod 24 is inserted by aligning it with the hole on the combination plate 21. After insertion, the combination rod 24 will completely penetrate the insert block 27. After penetration, it is fixed by screwing the nut 26 onto the threaded post 25. After fixing, the internal structure is as follows. Figure 3As shown, this completes the fixing of the combination plate 21 and the clamp 1. As needed, different numbers of clamps 1 can be combined on the bottom plate 22, so that the overall length of the clamp 1 can be changed at will to suit the rated primary current of high voltage electrical appliances of different sizes.

[0053] When the combination rod 24 is not inserted, the trapezoidal plug 32 is located inside the insert block 27 under the action of the spring 33. When the combination rod 24 is inserted, the threaded post 25 on the combination rod 24 will first contact the trapezoidal plug 32. Under the action of the inclined side of the trapezoidal plug 32, the trapezoidal plug 32 will be squeezed upward. When the trapezoidal plug 32 is squeezed upward, the spring 33 is contracted. Since the trapezoidal plug 32 and the slide groove 31 are in a sealed state, when the trapezoidal plug 32 moves upward, the air above the slide groove 31 is compressed. When the trapezoidal plug 32 moves upward, the compressed air will enter the circular groove 35 through the connecting groove 34. The air entering the circular groove 35 is blocked by the baffle 36 and will enter the sliding groove. The air inside the sliding groove will compress the piston block 37 inside. As the piston block 37 moves outward, it will drive the insertion rod 38 to move outward synchronously. It will also move to the outside through the second limiting ring 310. After the clamp 1 is fixed, the sliding groove inside the clamp 1 will correspond to the insertion groove inside the adjacent clamp 1. This allows the insertion rod 38 to be inserted into the adjacent insertion groove when it moves outward. When a single clamp 1 is fixed by the combination rod 24, adjacent clamps 1 can be combined together by the insertion rod 38. When the combined clamps 1 are used to fix the wire, they can simultaneously compress the wire inside each clamp 1, thus achieving a better wire fixing effect.

[0054] By rotating the outer terminal block 5, the rotation of the terminal block 5 drives the rotating shaft to rotate, which in turn drives the screw 44 to rotate. By rotating the screw 44, the two sliders 45 on it can move synchronously in opposite directions. The synchronous reverse movement of the sliders 45 can change the included angle of the two connecting rods 46 on the same locking block 43. After the included angle of the connecting rods 46 is changed, the locking block 43 will move. After the locking block 43 moves out of the bottom plate 22, the fixing of the fixing block 41 can be released. Thus, by rotating the screw 44, the fixing effect between the fixing block 41 and the bottom plate 22 can be changed. This allows the terminal block 5 to be disassembled and installed by rotating the terminal block 5. Terminal blocks 5 of different sizes can be assembled by fixing blocks 41, allowing different sizes of terminal blocks 5 to be freely combined according to the rated primary current of the high-voltage electrical appliances and the user's requirements.
