Description

Technical Field

[0001] The present invention belongs to the technical field of electric power fittings, and in particular relates to a multifunctional connection type electric power fitting. Background Art

[0002] Electrical fittings are used to connect and combine various devices in the power system. They not only connect the various devices in the power system into a whole, ensuring the continuity and stability of power transmission, but also withstand the mechanical and electrical loads transmitted by the conductors and other fittings, ensuring the safe operation of the power system. These fittings are typically made of high-strength, corrosion-resistant iron or aluminum materials to withstand the various harsh climatic conditions in outdoor environments.

[0003] Traditional electrical hardware typically connects conductors using bolts and nuts. While this method meets the basic needs of power systems to a certain extent, its cumbersome and time-consuming operation is becoming increasingly prominent. Furthermore, improper tightening force can lead to poor fixing, making it difficult to clamp conductors of varying diameters and materials, significantly inconvenient for power system maintenance and repair. More critically, traditional connection methods are inadequate for connecting conductors in different directions, failing to meet the increasingly complex demands of power systems.

[0017] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0018] refer to Figures 1 to 7 The embodiment of the present invention provides a multifunctional connecting type electric power fitting. Figure 1 FIG. 1 is a schematic diagram of the overall structure of an embodiment of the present invention, as shown in FIG. Figure 1 As shown, the multifunctional connecting electrical fitting includes a semicircular barrel-shaped wire clamp. Two of these wire clamps 1 are combined and connected to form a single wire clamp. Each electrical fitting is composed of two of these wire clamps, with an angle adjustment mechanism 2 provided between the two sets of these clamps. The design of combining two of these wire clamps 1 into a single clamp facilitates installation and removal, as well as clamping and securing wires. The angle adjustment mechanism 2 is used to adjust the angle between the two clamps to accommodate wire connections in different directions.

[0019] like Figures 2 to 4As shown, the two sets of wire clamps that make up each electrical hardware are arranged vertically relative to each other. The angle adjustment mechanism 2 includes a first central shaft 21 fixedly connected to the lower side of the wire clamp at the top. A first bevel tooth 22, a U-shaped member 23, and a connecting ring 24 are sequentially sleeved on the first central shaft 21 from bottom to top. A second central shaft 25 is inserted through each curved surface of the U-shaped member 23. A second bevel tooth 26 is sleeved on each of the second central shafts 25. The first bevel tooth 22 meshes with two of the second bevel teeth 26. The other sides of the two second bevel teeth 26 are meshed with third bevel teeth 27. A third central shaft 201 is inserted through the center of the third bevel tooth 27. The lower end of the third central shaft 201 is fixedly connected to the wire clamp at the bottom.

[0020] When the upper wire clamp as a whole needs to rotate a certain angle relative to the lower wire clamp as a whole, the first bevel tooth 22 rotates with the upper wire clamp as a whole via the first central axis 21. It is worth noting that the first bevel tooth 22, the U-shaped member 23, and the first central axis 21 are fixedly connected by a flat key, that is, the first bevel tooth 22 and the U-shaped member 23 cannot rotate relative to the first central axis 21; the third bevel tooth 27 and the third central axis 201 are connected by an axial hole, and the third bevel tooth 27 can rotate relative to the third central axis 201; the connecting ring 24 and the first central axis 21 are also connected by an axial hole, that is, the connecting ring 24 can rotate relative to the first central axis 21. The first bevel tooth 22 is meshed and driven by the second bevel tooth 26, causing the third bevel tooth 27 to rotate relative to the first central axis 21, thereby achieving the required angle adjustment between the upper wire clamp as a whole and the lower wire clamp as a whole.

[0021] like Figures 3 and 4 As shown, the third bevel gear 27 includes an inner meshing ring 271 that meshes with the third bevel gear 27, and an outer positioning ring 272 that serves as a positioning mechanism. The inner meshing ring 271 and the outer positioning ring 272 are fixedly connected. The connecting ring 24 is cylindrical, and the lower end of the connecting ring 24 surrounds the outer side of the inner meshing ring 271. The inner meshing ring 271 is provided with an annular retaining groove 28, and the inner side of the lower end of the connecting ring 24 is provided with an annular protrusion 241 that is inserted into the limiting groove 28. A plurality of balls 29 are rollingly connected between the annular protrusion 241 and the inner meshing ring 271.

[0022] The meshing inner ring 271 is used to mesh with the second bevel teeth 26, and the annular protrusion 241 is inserted into the limiting groove 28 to tightly connect the upper and lower wire clamps. A plurality of balls 29 are connected by a rolling connection between the annular protrusion 241 and the meshing inner ring 271, ensuring the stability of the relative angular rotation of the upper and lower wire clamps.

[0023] In some optional embodiments, the annular protruding structure 241, the meshing inner ring 271 and the ball 29 are coated with lubricating oil, which helps to reduce friction between the contact parts of the structure, and also helps to reduce wear and extend the service life.

[0024] In certain preferred embodiments, Figure 2 and Figure 5 As shown, the lower wire clamp as a whole is located on one side of the angle adjustment mechanism 2 and is also fixedly provided with a locking mechanism 3. The locking mechanism 3 includes a support seat 39 fixedly connected to the lower wire clamp as a whole. A second shaft cylinder 37 is fixedly provided on the upper end of the support seat 39 close to the side of the angle adjustment mechanism 2. A fixing cover 36 is glued to the other end of the second shaft cylinder 37. A third shaft cylinder 38 is glued to the outer side of the fixing cover 36. A first shaft cylinder 33 is passed through the third shaft cylinder 38. The third shaft cylinder 38 and the first shaft cylinder 33 are slidably connected. A first spring 35 is provided in the first shaft cylinder 33. An adjustment column 34 is passed through the first spring 35. A connecting block 32 is fixedly connected to the end of the connecting block 32 away from the support seat 39. A positioning screw 31 is threadedly connected to the connecting block 32.

[0025] The locking mechanism 3 is used to lock the angle between the upper wire clamp as a whole and the lower wire clamp as a whole after the angle adjustment mechanism 2 has adjusted the angle between the two. The support seat 39 is the base part of the locking mechanism 3 and is fixedly connected to the wire clamp as a whole. The second shaft cylinder 37, the fixed cover 36 and the third shaft cylinder 38 are in a fixed state. Pulling the connecting block 32 can drive the adjusting column 34 to translate in the direction away from the supporting seat 39, and the first spring 35 is extended accordingly. When the external tension disappears, the first spring 35 naturally retracts, driving the connecting block 32 and the adjusting column 34 to translate in the direction close to the supporting seat 39.

[0026] In certain preferred embodiments, Figure 3As shown, the outer positioning ring 272 is further provided with a plurality of positioning grooves 20. The positioning grooves 20 are arranged in two circles, one inside and one outside, and the positioning grooves 20 in the two circles are staggered. The positioning grooves 20 are used to provide locking points. The staggered distribution of the positioning grooves 20 in the two circles allows locking at multiple different angles, providing more self-locking rotation angle options.

[0027] In certain preferred embodiments, Figure 5 As shown, the positioning screw 31 is composed of an upper threaded portion and a lower cylindrical portion. The diameter of the threaded portion is larger than that of the cylindrical portion. The connecting block 32 is provided with a threaded hole that is compatible with the threaded portion. The design of the threaded portion having a larger diameter than the cylindrical portion facilitates smooth installation and removal of the positioning screw 31 from the connecting block 32.

[0028] In certain preferred embodiments, Figure 5 As shown, the cylindrical portion of the set screw 31 fits within the positioning slot 20, with the lower end of the cylindrical portion inserted into the positioning slot 20. With the set screw 31 inserted into the positioning slot 20, the third bevel gear 27 is no longer able to rotate about the third central axis 201. This means that the first bevel gear 22, the second bevel gear 26, and the third bevel gear 27 are no longer able to rotate relative to each other through engagement, thereby locking the angle adjustment mechanism 2 and fixing the angle between the upper and lower wire clamps. To adjust the angle, the set screw 31 is rotated in the opposite direction to remove it from the positioning slot 20.

[0029] At the same time, pulling the connecting block 32 can drive the adjusting column 34 to translate away from the supporting seat 39, so that the positioning screw 31 can be inserted into the positioning groove 20 of the inner ring. When the connecting block 32 is pushed toward the supporting seat 39, the first spring 35 naturally retracts, allowing the positioning screw 31 to be inserted into the positioning groove 20 of the outer ring. This provides more self-locking rotation angles between the upper and lower wiring clamps.

[0030] In certain preferred embodiments, Figure 6As shown, a block 341 is glued to one end of the adjustment column 34 near the support seat 39. A slot 361 is defined on the side of the fixing cover 36 near the support seat 39. The block 341 and slot 361 correspond to and fit together in a front-to-back manner. Both the block 341 and slot 361 are made of magnetic material. When the connecting block 32 is pulled, the adjustment column 34 is translated away from the support seat 39. When the positioning screw 31 is inserted into the positioning slot 20 of the inner ring, the block 341 fits neatly into the slot 361. Because the block 341 and slot 361 are magnetic and attract each other, they offset the natural retraction force of the first spring 35, allowing the block 341 to extend stably, thereby more stably inserting the positioning screw 31 into the positioning slot 20 of the inner ring. When the connecting block 32 is pushed toward the supporting seat 39 , the adjusting column 34 and the clamping block 341 are away from the clamping slot 361 , and the clamping block 341 and the clamping slot 361 are no longer attracted to each other.

[0031] In certain preferred embodiments, Figure 1 As shown, fixing blocks 11 are fixedly provided on both sides of the cross-section of each wire clamp body 1. When two wire clamp bodies 1 are combined to form the wire clamp as a whole, the two sets of fixing blocks 11 on the two wire clamp bodies 1 fit together in a vertical position, and the two sets of fixing blocks 11 are connected by screws 12. The fixing blocks 11 on the two wire clamp bodies 1 are connected by the screws 12, thereby forming a complete wire clamp as a whole for clamping the wire.

[0032] In certain preferred embodiments, Figure 2 and Figure 7 As shown, each of the two ends of the wire clamp body 1 is provided with a conical tightening adjustment mechanism 4. Each conical tightening adjustment mechanism 4 includes a conical flexible pad 41. The thinner end of the conical flexible pad 41 is located at the end of the wire clamp body 1. Both ends of the wire clamp body 1 are provided with an outer ring thread 13. The outer ring threads 13 of the two wire clamp bodies 1 form the two parts of the wire clamp as a whole. The outer ring threads 13 are combined to form a full-circle thread, and the full-circle thread is threadedly connected to a thread ring 42. Each set of the conical tightening adjustment mechanism 4 is symmetrically distributed at both ends of the wire clamp as a whole. By rotating the thread ring 42 to move on the outer ring thread 13, the clamping force of the conical flexible pad 41 on the wire and other objects can be adjusted. This can be adjusted according to the diameter and material of the wire to be clamped, ensuring that the wire is firmly clamped in the wire clamp as a whole while avoiding damage to the wire.

[0033] In certain preferred embodiments, Figure 2 and Figure 7As shown, an elastic force adjustment mechanism 5 is also provided between the two groups of the cone tightening adjustment mechanisms 4 in the wire clamp split 1. The elastic force adjustment mechanism 5 includes a plurality of second springs 51 fixedly connected to the inner side of the wire clamp split 1. The other ends of the plurality of second springs 51 are fixedly connected to a fastening clamp 52. The fastening clamp 52 is in the shape of a semicircular barrel with an outer diameter smaller than the inner diameter of the wire clamp split 1, and the fastening clamp 52 is made of an elastic material. While the cone tightening adjustment mechanism 4 clamps the conductor, the elastic force adjustment mechanism 5 also plays a role in clamping the conductor. The second spring 51 uses its elastic force to push the fastening clamp 52 toward the conductor. Since the fastening clamp 52 is made of an elastic material, it can fit tightly to the surface of the conductor, further increasing the stability of the clamping. At the same time, the semicircular barrel design of the fastening clamp 52 enables it to adapt to conductors of different diameters, providing additional clamping flexibility.

[0034] In the above embodiment, the angle adjustment method of a multifunctional connecting electrical fitting is characterized by first installing one of the two wires to be connected using the electrical fitting in one of the wire clamp assemblies, at which time the angle adjustment mechanism 2 is not locked, and then rotating the other wire clamp assembly.

[0035] When the upper wire clamp as a whole is rotated, the first bevel tooth 22 rotates accordingly, and the first bevel tooth 22 engages with the two second bevel teeth 26 and rotates around the second center axis 25. The other side of the two second bevel teeth 26 engages with the third bevel tooth 27 and rotates around the third center axis 201 to adapt to the angle change. At the same time, the first bevel tooth 22 and the connecting ring 24 are connected to the third bevel tooth 27 through the annular protruding structure 241 and the ball 29 and rotate relative to each other, thereby realizing the connection and relative angle adjustment function between the two wire clamps as a whole.

[0036] When the lower wire clamp as a whole is rotated, the third bevel tooth 27 rotates around the third center axis 201, and at the same time, the third bevel tooth 27 engages with the two second bevel teeth 26 and rotates around the second center axis 25. At the same time, the other sides of the two second bevel teeth 26 engage with the first bevel teeth 22, so that the third bevel tooth 27 and the first bevel tooth 22 rotate relative to each other to adapt to the angle change. At the same time, the connecting ring 24 is connected to the third bevel tooth 27 through the annular protruding structure 241 and the ball 29 and rotates relative to each other, realizing the connection and relative angle adjustment functions between the two wire clamps as a whole.

[0038] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the aforementioned embodiments, or that some of the technical features may be replaced with equivalents.
