[0035] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0036] Example 1

[0037] refer to Figure 1 As shown, an embodiment of the present application provides a suspension clamp structure 100 , which includes a suspension insulator 110 , a connecting plate assembly 120 , a clamp assembly 130 , a connecting rope 160 , a cable 140 and a pre-twisted wire 150 .

[0038] Specifically, combined Figure 2 and Figure 3As shown, the connecting plate assembly 120 includes a connecting plate 121 and a first hanging ear 122, one end of the connecting plate 121 is movably connected to one end of the suspension insulating member 110, and the end of the connecting plate 121 away from the suspension insulating member 110 is movably connected to the first hanging ear 122; the wire clamp assembly 130 is movably connected to the end of the first hanging ear 122 away from the connecting plate 121, and the wire clamp assembly 130 defines an accommodating channel 131; the opposite ends of the connecting rope 160 are respectively connected to the wire clamp assembly 130 and the connecting plate 121; the cable 140 is passed through the accommodating channel 131; the pre-twisted wire 150 is wrapped around the cable 140, and a part of the pre-twisted wire 150 is located between the cable 140 and the accommodating channel Between the side walls of the channel 131, the wire clamp assembly 130 is movably connected to the suspension insulating member 110 through the connecting plate assembly 120, so that the cable 140 on the wire clamp assembly 130 has a certain swing amplitude and adjustment range, and the wire clamp assembly 130 forms a hanging structure, and the connecting rope 160 protects the hanging connection of the wire clamp assembly 130, and the flexibly connected connecting rope 160 will not cause obstruction and influence on the connecting plate assembly 120 and the wire clamp assembly 130. When the wire clamp assembly 130 is detached or separated from the connecting plate assembly 120, the connecting rope 160 can prevent the wire clamp assembly 130 and the cable 140 from falling directly, thereby improving the safety performance of the hanging wire clamp structure 100, and the cable 140 is clamped and fixed by the wire clamp assembly 130 to ensure that the cable 140 has a stable diversion path.

[0039] It is understandable that suspension insulators are installed on transmission towers, playing the dual role of insulation and supporting the conductors, maintaining the current flowing only in the conductors and preventing leakage to the tower or the ground.

[0040] Optionally, the wire clamp assembly 130 includes a protective pad and a wire clamp, the pre-twisted wire 150 is arranged between the protective pad and the wire clamp, the protective pad is sleeved on the cable 140, and the wire clamp is used to connect the connecting plate assembly 120.

[0041] It should be noted that the reference Figures 1 to 3 As shown, the first direction X is taken as the width direction of the suspension wire clamp structure 100, the second direction Y is taken as the length direction of the suspension wire clamp structure 100, and the third direction Z is taken as the height direction of the suspension wire clamp structure 100. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. It should be understood that the above definitions are merely for facilitating understanding of the relative positional relationship of the suspension wire clamp structure 100 and should not be construed as limiting the present application.

[0042] In the related art, the double-wire cable 140 may have a local temperature that is too high due to the different tensions of the two cables 140 and the unbalanced current load. The connection position of the two cables 140 may be subjected to overcurrent and may cause discharge ablation. The two cables 140 may affect and hinder each other, so that the connection position of the two cables 140 affects the connection and conduction status of the cables 140, affecting the normal operation and use of the two cables 140.

[0043] In one embodiment, optionally, reference Figure 2 As shown, the number of the first hanging ears 122 is two, and the two first hanging ears 122 are respectively arranged at the opposite ends of the connecting plate 121 along the first direction X. The number of the cables 140 is two, and one first hanging ear 122 is connected to one cable 140 through one wire clamp assembly 130. Accordingly, by using the connecting plate 121 and the first hanging ear 122 in combination, one connecting plate 121 can connect the two first hanging ears 122 accordingly, so that the two cables 140 can be adjusted and operated independently, reducing the influence and obstruction between the two cables 140, forming a stable current path, and thereby extending the service life of the cable 140.

[0044] Optionally, combined Figure 3 and Figure 4 As shown, a first mounting groove 1221 is provided at one end of the first hanging ear 122, and second mounting holes 1222 are provided on both opposite side walls of the first mounting groove 1221. The connecting plate 121 is provided with a first mounting hole 1211, and a first bolt is passed through the first mounting hole 1211 and the second mounting hole 1222, so that the connecting plate 121 can rotate relative to the first hanging ear 122 with the first bolt as the axis, so as to facilitate rotation adjustment relative to the connecting plate 121 through the first hanging ear 122, and has a certain adjustment range.

[0045] In one embodiment, optionally, reference Figure 2 As shown, the two cables 140 are arranged in parallel, and the cables 140 extend along the second direction Y, that is, each cable 140 extends along the second direction Y, and the two cables 140 are parallel to each other and arranged side by side, and the second direction Y is perpendicular to the first direction X. The two cables 140 remain independent of each other and will not affect each other, so as to keep the two cables 140 safe and regular.

[0046] In summary, the wire clamp assembly 130 of the suspension wire clamp structure 100 is movably connected to the suspension insulating member 110 through the connecting plate assembly 120, so that the cable 140 on the wire clamp assembly 130 has a certain swing amplitude and adjustment range, and the wire clamp assembly 130 forms a suspension structure. The connecting rope 160 protects the suspension connection of the wire clamp assembly 130, and the flexibly connected connecting rope 160 will not cause obstruction and influence on the connecting plate assembly 120 and the wire clamp assembly 130. When the wire clamp assembly 130 is detached or separated from the connecting plate assembly 120, the connecting rope 160 can prevent the wire clamp assembly 130 and the cable 140 from falling directly, thereby improving the safety performance of the suspension wire clamp structure 100. The cable 140 is clamped and fixed by the wire clamp assembly 130, ensuring that the cable 140 has a stable conduction path, reducing the situation where the cable 140 has poor contact and causes discharge or ablation.

[0047] Example 2

[0048] refer to Figures 1 to 3 As shown, an embodiment of the present application provides another suspension clamp structure 100 , which includes a suspension insulator 110 , a connecting plate assembly 120 , a clamp assembly 130 , a connecting rope 160 , a cable 140 and a pre-twisted wire 150 .

[0049] Specifically, combined Figure 2 and Figure 3 As shown, the connecting plate assembly 120 includes a connecting plate 121 and a first hanging ear 122, one end of the connecting plate 121 is movably connected to one end of the suspension insulating member 110, and the end of the connecting plate 121 away from the suspension insulating member 110 is movably connected to the first hanging ear 122; the wire clamp assembly 130 is movably connected to the end of the first hanging ear 122 away from the connecting plate 121, and the wire clamp assembly 130 defines an accommodating channel 131, and the wire clamp assembly 130 is movably connected to the suspension insulating member 110 through the connecting plate assembly 120, so that the cable 140 on the wire clamp assembly 130 has a certain swing amplitude and adjustment range, and the wire clamp assembly 130 forms a hanging structure.

[0050] In this embodiment, the opposite ends of the connecting rope 160 are respectively connected to the wire clamp assembly 130 and the connecting plate 121; the cable 140 is passed through the accommodating channel 131; the pre-twisted wire 150 is wrapped around the cable 140, and a partial area of ​​the pre-twisted wire 150 is located between the cable 140 and the side wall of the accommodating channel 131. The connecting rope 160 protects the hanging connection of the wire clamp assembly 130, and the flexibly connected connecting rope 160 will not cause obstruction and influence on the connecting plate assembly 120 and the wire clamp assembly 130. When the wire clamp assembly 130 and the connecting plate assembly 120 are detached or separated, the connecting rope 160 can prevent the wire clamp assembly 130 and the cable 140 from falling directly, thereby improving the safety performance of the suspended wire clamp structure 100. The cable 140 is clamped and fixed by the wire clamp assembly 130 to ensure that the cable 140 has a stable diversion path.

[0051] It should be noted that the reference Figures 1 to 3 As shown, the first direction X takes the width direction of the suspension clamp structure 100 as an example, the second direction Y takes the length direction of the suspension clamp structure 100 as an example, and the third direction Z takes the height direction of the suspension clamp structure 100 as an example, wherein the first direction X, the second direction Y and the third direction Z are arranged perpendicularly to each other.

[0052] In one embodiment, optionally, reference Figure 2 As shown, there are two first hanging ears 122, which are respectively disposed at opposite ends of the connecting plate 121 along the first direction X. There are two cables 140, and one first hanging ear 122 is connected to one cable 140 via one wire clamp assembly 130. Accordingly, through the cooperation between the connecting plate 121 and the first hanging ears 122, one connecting plate 121 can connect two first hanging ears 122, allowing the two cables 140 to be adjusted and operated independently, reducing the mutual influence and obstruction between the two cables 140, forming a stable current path, and thereby extending the service life of the cables 140. Exemplarily, the connecting plate 121 is a multi-angle connecting plate, so that any corner of the connecting plate 121 can be used as a connection point for connecting various components to achieve a stable and adjustable connection. This can distribute the connection load, increase the stability of the structure, and allow a certain range of angle adjustment, making it suitable for applications with dynamic loads or those requiring fine-tuning.

[0053] Optionally, combined Figure 3 and Figure 4As shown, a first mounting groove 1221 is provided at one end of the first mounting groove 1221, and second mounting holes 1222 are provided on opposite side walls of the first mounting groove 1221. The connecting plate 121 is provided with a first mounting hole 1211, and a first bolt is passed through the first mounting hole 1211 and the second mounting hole 1222, so that the connecting plate 121 can rotate relative to the first mounting groove 122 with the first bolt as the axis, so as to facilitate rotational adjustment relative to the connecting plate 121 via the first mounting groove 122, with a certain adjustment range. Exemplarily, the opposite side walls of the first mounting groove 1221 are two single ears of the first mounting groove 122, and the two single ears are arranged opposite each other so that the two single ears can be used in conjunction with the first bolt and connected via a nut.

[0054] Furthermore, a spring washer is included, which abuts between the nut and the single ear to generate continuous pressure on the nut, thereby enhancing the stability of the connection to prevent the nut from falling off due to vibration or loosening.

[0055] Alternatively, as Figure 3 As shown, the wire clamp assembly 130 is provided with a second mounting groove 132 at one end away from the accommodating channel 131, and fourth mounting holes 133 are provided on the opposite side walls of the second mounting groove 132. The first hanging ear 122 is provided with a hanging portion 1223 at one end away from the first mounting groove 1221, and the hanging portion 1223 is provided with a third mounting hole 1224, and a second bolt is passed through the fourth mounting hole 133 and the third mounting hole 1224, so that the hanging portion 1223 of the first hanging ear 122 can rotate relative to the wire clamp assembly 130 with the second bolt as the axis, so as to facilitate rotation adjustment relative to the wire clamp assembly 130 through the hanging portion 1223 of the first hanging ear 122, and the wire clamp assembly 130 is connected through the hanging portion 1223 of the first hanging ear 122. The wire clamp assembly 130 allows a certain angle adjustment range, which is convenient for releasing the stress of the cable 140 on the wire clamp assembly 130 and maintaining the stability of the suspended wire clamp structure 100.

[0056] Optionally, refer to Figure 2 As shown, the axial direction of the rotation axis of the wire clamp assembly 130 is perpendicular to the axial direction of the rotation axis of the connecting plate 121, that is, the rotation direction of the wire clamp assembly 130 is different from the rotation direction of the connecting plate 121, which facilitates the cable 140 connected to the wire clamp assembly 130 to have rotation adjustment methods in different directions, thereby improving the adjustment range of the suspension wire clamp structure 100 for the cable 140.

[0057] In one embodiment, optionally, in combination Figure 3 and Figure 5As shown, the opposite ends of the connecting rope 160 are respectively provided with a first crimping ring 161 and a second crimping ring 162, and the connecting plate 121 further includes a fifth mounting hole 1212, the first crimping ring 161 corresponds to the fifth mounting hole 1212, and is fixedly connected to the first crimping ring 161 and the fifth mounting hole 1212 by a third bolt, the second crimping ring 162 is sleeved on the second bolt, and the second crimping ring 162 abuts between the hanging portion 1223 and the side wall of the second mounting groove 132, through the first crimping ring 161 and The second crimping ring 162 enables the two ends of the connecting rope 160 to be connected more stably, preventing the connecting rope 160 from falling off. The connecting rope 160 protects the connection of the wire clamp assembly 130, and the flexibly connected connecting rope 160 will not cause any obstruction or impact on the connecting plate assembly 120 and the wire clamp assembly 130. When the wire clamp assembly 130 is detached or separated from the connecting plate assembly 120, the connecting rope 160 can prevent the wire clamp assembly 130 and the cable 140 from falling directly, thereby improving the safety performance of the suspended wire clamp structure 100 and ensuring the connection effect of the connecting rope 160.

[0058] In one embodiment, optionally, reference Figure 2 As shown, the two cables 140 are arranged in parallel, and the cables 140 extend along the second direction Y, that is, each cable 140 extends along the second direction Y, and the two cables 140 are parallel to each other and arranged side by side, the second direction Y is perpendicular to the first direction X, and the two cables 140 remain independent.

[0059] In one embodiment, optionally, the suspension insulating member 110, the connecting plate assembly 120 and the wire clamp assembly 130 are arranged in sequence along a third direction Z, and the third direction Z is perpendicular to the first direction X and the second direction Y, respectively, that is, the suspension insulating member 110, the connecting plate assembly 120 and the wire clamp assembly 130 are arranged along the height direction of the suspension wire clamp structure 100, and the connecting plate assembly 120 is located between the suspension insulating member 110 and the wire clamp assembly 130.

[0060] Optionally, the suspension insulator 110 includes a second mounting lug 111, one end of which is movably connected to the connecting plate 121 via the second mounting lug 111.
