Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a bundled tension clamp. Background Technology

[0002] In the field of power transmission, tension clamps are key components used to fix conductors and withstand conductor tension. Traditional tension clamps have some defects in their structural design. For example, their fastening components generally use bolt structures, which can easily loosen during long-term use due to conductor tension and external environmental factors. This can affect the fixing effect on the conductor and may even lead to safety accidents.

[0003] In addition, conductors generate heat during current transmission. If this heat cannot be dissipated in time, it will accelerate conductor aging and reduce conductor lifespan. Existing tension clamps generally clamp the conductor directly, causing the insulation layer of the clamped section of the conductor to be completely sealed by the metal cavity. This prevents the heat generated by the conductor during operation from being effectively dissipated, and long-term high temperatures can easily accelerate insulation aging and even cause carbonization breakdown.

[0004] Therefore, this application provides a bundled tension clamp to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a bundled tension clamp to solve the technical problems of poor fastening stability caused by loose bolts and accelerated insulation aging caused by the fully enclosed clamping structure hindering heat dissipation of the conductor.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A bundled tension clamp includes an integrally formed aluminum body. Flame-retardant clamps are provided on both the upper and lower sides of the integrally formed aluminum body. A metal shell is provided on the side of each of the two flame-retardant clamps away from each other. A stud is provided between the two metal shells, penetrating the integrally formed aluminum body and the flame-retardant clamps. The end of the stud protrudes from the outside of the integrally formed aluminum body and is threaded with a nut. A positioning ring is fixed to the bottom of the nut. A reinforcing block is fixed to the middle of the outside of the integrally formed aluminum body. A reinforcing block is installed at the end of the reinforcing block and is inserted into the side wall of the positioning ring.

[0008] A clamping cavity for wires to pass through is formed between the flame-retardant clamping plate and the metal shell. The inner wall of the clamping cavity is fixed with multiple friction ridges, and ventilation holes are opened at the same position on the multiple friction ridges.

[0009] Optionally, the two sides of the integrally formed aluminum body are symmetrically fixed with fixing ears, and a thickened pull ring is installed on both fixing ears.

[0010] Optionally, at least two sets of studs and nuts are provided, and the reinforcing block is located between two nuts.

[0011] Optionally, two positioning plates are provided and are horizontally inserted into both ends of the reinforcing block via springs, and the two positioning plates are respectively horizontally inserted into the two positioning rings.

[0012] Optionally, the ventilation holes at the same position on multiple friction edges together form a longitudinal heat dissipation air duct.

[0013] Optionally, a longitudinal drain groove is provided in the middle of the inner wall of the clamping cavity.

[0014] Optionally, the bottom of the sewage trough is inclined at one end.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, thanks to the setting of the reinforcing block and the positioning plate, the positioning plate can be used to abut against the positioning ring, thereby reinforcing the tightened nut and preventing it from loosening.

[0017] In the above solution, thanks to the setting of friction ridges, ventilation holes and drain troughs, the friction ridges can be used to ensure the effect of clamping and fixing the wires, the air duct formed by the ventilation holes can ensure the heat dissipation of the wires, and the drain trough can be used to prevent water accumulation in the clamping cavity from corroding the wires.

[0018] In summary, this device not only ensures the fixing effect after the bolts are tightened, but also ensures heat dissipation for the clamped and fixed wires, resulting in good overall performance. Attached Figure Description

It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0028] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0029] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0030] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0031] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings.

[0032] like Figure 1-4 As shown, an embodiment of this utility model provides a bundled tension clamp, the main structure of which is an integrally formed aluminum body 1. Fixing ears 101 are symmetrically fixed on both sides of the integrally formed aluminum body 1, and a thickened pull ring 102 is installed on both fixing ears 101.

[0033] Flame-retardant clamping plates 2 are provided on both the upper and lower sides of the one-piece molded aluminum body 1. Metal shells 3 are provided on the side of the two flame-retardant clamping plates 2 that is away from each other. A stud 4 is provided between the two metal shells 3, penetrating the one-piece molded aluminum body 1 and the flame-retardant clamping plates 2. The end of the stud 4 protrudes out of the outside of the one-piece molded aluminum body 1 and is threaded with a nut 5, which is tightly engaged with the stud 4 to achieve the fastening of the entire structure.

[0034] The nut 5 has a positioning ring 501 fixed to its bottom. The positioning ring 501 is integrally formed with the nut 5 and is made of the same material. A reinforcing block 6 is fixed to the middle of the outer side of the integrally formed aluminum body 1. The reinforcing block 6 is fixed to the integrally formed aluminum body 1 by welding. Two positioning plates 601 are horizontally inserted into the end of the reinforcing block 6 via springs. The springs 602 are made of high-quality stainless steel. The positioning plates 601 can pop out horizontally under the action of the springs and insert horizontally into the positioning ring 501, thereby reinforcing the tightened nut 5 and preventing the nut 5 from loosening due to vibration or other reasons during long-term use.

[0035] In this specific implementation, two sets of studs 4 and nuts 5 are provided, and two positioning plates 601 are provided, located between the two sets of studs 4 and nuts 5.

[0036] A clamping cavity 201 is formed between the flame-retardant clamping plate 2 and the metal outer shell 3, allowing the wire to pass through. The clamping cavity 201 can tightly wrap the wire, ensuring effective fixation. In this embodiment, multiple friction ridges 202 are fixed to the inner wall of the clamping cavity 201. The friction ridges 202 are distributed in a strip shape, which can increase the friction between the wire and the clamping cavity, further ensuring the effectiveness of clamping and fixing the wire. Ventilation holes 203 are opened at the same position on the multiple friction ridges 202. These ventilation holes 203 together form a longitudinal heat dissipation channel. When the wire generates heat while transmitting current, air can circulate through the heat dissipation channel to carry away the heat, thereby ensuring the heat dissipation effect of the wire and extending the service life of the wire.

[0037] In addition, a longitudinal drainage groove 204 is provided in the middle of the inner wall of the clamping cavity 201. The bottom of the drainage groove 204 is inclined to one end at an angle of 5°-10°. This design allows rainwater, dust, etc., to be discharged along the inclined direction of the drainage groove 204 after entering the clamping cavity 201, avoiding water and dust accumulation in the clamping cavity 201. In specific implementation, the surface of the drainage groove 204 is smoothed, for example, by using a polishing process to achieve a surface roughness of Ra0.8-Ra1.6, reducing the adhesion of dirt and facilitating cleaning.

[0038] The working principle of this utility model is as follows: In actual use, the construction personnel first pass the conductor through the clamping cavity 201, and then fasten the two metal shells 3, the flame-retardant clamping plate 2, and the one-piece molded aluminum body 1 together using studs 4 and nuts 5. Next, the positioning insert plate 601 is popped out and inserted into the positioning ring 501 to reinforce the nut 5. Finally, the tension clamp is installed onto the corresponding power facility using the thickened pull ring 102. Through the above structural design and usage, this bundled tension clamp not only effectively solves the problem of easy loosening of the fastening components of traditional tension clamps, but also ensures heat dissipation of the conductor and prevents corrosion from water and dust accumulation. It has good overall performance and high practical value and promotional significance.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
