[0053] Through the above-mentioned drawings, specific embodiments of this application have been shown, and there will be a more detailed description hereinafter. These drawings and the written description are not intended to limit the scope of the concept of this application in any way, but to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. Detailed Description of the Invention

[0054] Here, exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. On the contrary, they are merely examples of devices consistent with some aspects of this application as detailed in the appended claims.

[0055] The term "and / or" herein only describes an association relationship, indicating that three relationships may exist. For example, A and / or B may represent the following three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the term "at least one" herein represents any combination of at least two of any one or more of a plurality of. For example, including at least one of A, B, and C may represent including any one or more elements selected from the set consisting of A, B, and C.

[0056] At present, the commonly used tension clamps on the line are single-plate tension clamps. In actual operation, single-plate tension clamps are prone to become hot, burn red or even melt due to the high temperature of the drainage plate, which poses a serious threat to the safe operation of the line.

[0057] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a single-board tension clamp provided in an embodiment of the present application. Figure 1 As shown, the single-plate tension clamp includes a steel anchor 11, a first aluminum tube 12, a second aluminum tube 13 and a guide plate 14, wherein the steel anchor 11 is connected to the first aluminum tube 12, the first aluminum tube 12 can be used to connect to the wire, the two ends of the guide plate 14 are respectively connected to the first aluminum tube 12 and the second aluminum tube 13, and the second aluminum tube 13 is used to connect to the wire, so that the wires respectively connected to the first aluminum tube 12 and the second aluminum tube 13 are connected through the guide plate 14.

[0058] At this time, by Figure 1 It can be seen that the guide plate 14 is generally formed by bending an aluminum tube and then pressing (or directly pressing), which makes the guide plate part relatively weak, and further causes the guide plate to become hot, generate heat, or even melt due to excessive temperature when the tension clamp is working. Therefore, a tension clamp with strong heat resistance is urgently needed.

[0059] At the same time, since the guide plate is relatively weak, if the wires connecting the first aluminum tube 12 and the second aluminum tube 13 are subjected to uneven force or sudden force changes, the guide plate 14 may be broken.

[0060] In addition, this type of tension clamp has certain installation / maintenance problems. If the wires connected to the first aluminum tube 12 and the second aluminum tube 13 are subjected to a large force, the installation / maintenance of the tension clamp is affected.

[0061] The strain clamp provided by the present application aims to improve the mechanical strength and heat resistance of the strain clamp through a double drainage plate structure, thereby enhancing the heat resistance of the strain clamp. At the same time, by providing a corrugated structure between the drainage plate and the drainage wire clamp, the contact area between the drainage plate and the drainage wire clamp is further increased, thereby further enhancing the heat resistance of the strain clamp. Moreover, the corrugated structure enables the drainage plate and the drainage wire clamp to be fixed together even when no fastening component (or some fastening components) is installed, making the strain clamp more convenient for installation and maintenance, and thus solving the above technical problems in the prior art.

[0062] The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0063] See Figure 2 , Figure 2 which is a schematic diagram of the strain clamp provided by the embodiment of the present application. Figure 1 As Figure 2 shown, the strain clamp includes: a steel anchor 21, a strain pipe 22, a drainage plate 23, a drainage wire clamp 24, and a fastening component 25.

[0064] Among them, the steel anchor 21 is connected to the strain pipe 22; the strain pipe 22 is welded to one end of the drainage plate 23; the drainage wire clamp 24 is connected to the other end of the drainage plate 23, and the drainage wire clamp 24 and the drainage plate 23 are fastened by the fastening component 25.

[0065] Among them, a first corrugation is provided on the drainage plate 23, and a second corrugation is provided on the drainage wire clamp 24; after the drainage plate 23 and the drainage wire clamp 24 are connected, the first corrugation and the second corrugation fit together.

[0066] In one example, see Figure 3 , Figure 3 which is a schematic diagram of the strain clamp provided by the embodiment of the present application. Figure 2 As Figure 3 shown, a first corrugation 26 can be provided on the inner side of the drainage plate 23, and a second corrugation 27 can be provided on the outer side of the drainage wire clamp 24, so that the first corrugation 26 and the second corrugation 27 can fit together.

[0067] In one example, the number of corrugations corresponding to the first corrugation 26 (or the number of corrugations corresponding to the second corrugation 27) can be one or multiple, which can be associated with the conductor to be fixed by the strain clamp here, and no specific limitation is made here. For example, when the conductor to be fixed by the strain clamp is under less stress and has a lower heat generation intensity, the number of corrugations corresponding to the first corrugation can be set to 1. When the conductor to be fixed by the strain clamp is under greater stress and has a higher heat generation intensity, the number of corrugations corresponding to the first corrugation can be set to 3, etc.

[0068] As can be seen from the above description, the strain clamp provided by the embodiment of the present application can improve the stress intensity and heat resistance of the strain clamp through the double drainage plate structure, thereby enhancing the heat resistance of the strain clamp. In addition, the strain clamp provided by the embodiment of the present application also provides corresponding corrugated structures on the inner side of the drainage plate and the outer side of the drainage clamp, which can further increase the contact area between the drainage plate and the drainage clamp, thereby alleviating the heat generation problem of the strain clamp and further enhancing the heat resistance of the strain clamp. At the same time, the corrugated structure on the inner side of the drainage plate and the corrugated structure on the outer side of the drainage clamp can enable the drainage plate and the drainage clamp to be partially fixed together by the acting force even when no bolt / nut is installed (or when the bolt / nut is installed), thus facilitating the installation and maintenance of the strain clamp.

[0069] See Figure 4 , Figure 4 is a schematic structural diagram of a drainage plate provided by the embodiment of the present application. As Figure 4 shown, the drainage plate 23 includes an opening area 40; the opening area 40 is used to divide the drainage plate 23 into a first plate portion 41 and a second plate portion 42. At this time, the first corrugation provided on the drainage plate 23 includes a third corrugation 43 and a fourth corrugation 44.

[0070] As Figure 4 shown, the third corrugation 43 is provided on the first plate portion 41, and the fourth corrugation 44 is provided on the second plate portion 42. At this time, the second corrugation provided on the drainage clamp 24 is respectively fitted with the third corrugation 43 and the fourth corrugation 44 through the opening area 40 to connect the drainage plate 23 and the drainage clamp 24.

[0071] In one example, the third corrugation 43 provided on the first plate portion 41 and the fourth corrugation 44 provided on the second plate portion 42 can be the same or different. For example, the third corrugation 43 can be set as a corrugation with a first radian, and the fourth corrugation 44 can be set as a corrugation with a second radian. At this time, the first radian and the second radian are different.

[0072] In another example, the third corrugation 43 and the fourth corrugation 44 can also be set at different heights. For example, the third corrugation 43 can be set at a first height of the first plate portion 41, and the fourth corrugation 44 can be set at a second height of the second plate portion 42. At this time, the first height and the second height are different.

[0073] There is no limitation on the styles corresponding to the third corrugation 43 and the fourth corrugation 44 here, and it is subject to meeting the actual needs.

[0074] In this implementation manner, the drainage plate can be divided into a first plate portion and a second plate portion through the opening area, so that the drainage plate can be connected to the drainage line clamp. At this time, by extruding the integrally formed drainage plate, the impact resistance, fatigue resistance, and electrical conductivity of the strain clamp can be enhanced, thereby improving the overall performance of the strain clamp.

[0075] In one example, in order to further improve the electrical conductivity of the connection area between the drainage plate and the drainage line clamp, a conductive grease can be applied to the contact surface where the drainage plate and the drainage line clamp are connected. On the one hand, it can enhance the electrical conductivity of the strain clamp, and on the other hand, it can also fill the gap caused by the processing technology between the drainage plate and the drainage line clamp, thereby avoiding the increase in resistance caused by the gap between the drainage plate and the drainage line clamp, and further avoiding the problem of the line clamp heating up.

[0076] In a possible implementation manner, the fastening assembly can include at least one bolt, and each bolt corresponds to at least one nut; at least one bolt hole is included in the drainage plate and the drainage line clamp. At this time, after each bolt passes through the bolt hole to connect the drainage plate and the drainage line clamp in series, it is connected to at least one nut.

[0077] See Figure 5 , Figure 5 which is a schematic structural diagram of a fastening assembly provided by an embodiment of the present application. As Figure 5 shown, the fastening assembly 25 can include 4 bolts 51, and each bolt 51 can correspond to 2 nuts 52. At this time, 4 bolt holes 53 are included in the drainage plate 23 and the drainage line clamp 24, so that after each bolt 51 passes through the corresponding bolt hole 53 to connect the drainage plate 23 and the drainage line clamp 24 in series, it is connected to the corresponding nut 52.

[0078] In this implementation manner, the fastening ability of the fastening assembly can be enhanced by the way of one bolt corresponding to multiple nuts, preventing the connection between the drainage plate and the drainage line clamp from loosening, thereby avoiding the problem of increased resistance caused by the loosening between the drainage plate and the drainage line clamp, and further avoiding the problem of the strain clamp heating up.

[0079] In a possible implementation manner, as Figure 5As shown, at least one bolt hole 53 included in the drainage plate and the drainage wire clamp can be arranged in multiple rows and columns; each bolt hole 53 is used to set a bolt 51 and at least one nut 52.

[0080] In this implementation, when using multiple bolts, it can avoid the problem that the strain clamp is too long caused by arranging the bolt holes corresponding to the multiple bolts in a single row, which will affect the installation and maintenance.

[0081] In a possible implementation, the fastening assembly in the embodiments of the present application may further include a disc spring. Among them, after each bolt passes through the bolt hole to connect the drainage plate and the drainage wire clamp in series, it is first connected to the disc spring and then connected to at least one nut.

[0082] See Figure 6 , Figure 6 which is a schematic structural diagram of another fastening assembly provided by the embodiments of the present application. As Figure 6 shown, after the bolt 51 connects the drainage plate 23 and the drainage wire clamp 24 in series, it is first connected to the disc spring 61 and then connected to at least one nut 52 (such as Figure 6 the two nuts shown).

[0083] This implementation can further improve the fastening effect of the fastening assembly according to the disc spring.

[0084] In a possible implementation, the thickness of the drainage plate is associated with the number of columns of the bolt holes included in the drainage plate; the length of the drainage plate is associated with the number of rows of the bolt holes included in the drainage plate.

[0085] Among them, the thickness of the drainage plate can be understood as the distance formed along the direction of the strain pipe 22 as Figure 3 shown. At this time, the number of columns of the bolt holes included in the drainage plate can be understood as the number of bolt holes determined along the direction of the strain pipe 22.

[0086] Among them, the length of the drainage plate can be understood as the distance formed along the direction of the drainage wire clamp 24 as Figure 3 shown. At this time, the number of rows of the bolt holes included in the drainage plate can be understood as the number of bolt holes determined along the direction of the drainage wire clamp.

[0087] This implementation can determine the size of the drainage plate according to the number of rows and columns of the bolt holes included in the drainage plate, thereby expanding the application scenarios and scope of application of the strain clamp.

[0088] It should be noted here that the size of the drainage plate is adapted to the size of the drainage wire clamp, which will not be elaborated in detail here.

[0089] In one example, when the drainage plate is as Figure 4As shown, it includes an opening area 40. When the drainage plate is divided into a first plate portion 41 and a second plate portion 42 based on the opening area 40, the corresponding drainage wire clamp may include a plate connection portion and a wire connection portion. Among them, the plate connection portion is used to be arranged within the opening area to connect the drainage wire clamp to the drainage plate; the wire connection portion is used to connect to the first wire.

[0090] See Figure 7 , Figure 7 which is a schematic structural diagram of a drainage wire clamp provided by an embodiment of the present application. As Figure 7 shown, the plate connection portion 71 of the drainage wire clamp may be provided with a second corrugation 27, and the second corrugation 27 corresponds to the third corrugation of the first plate portion of the drainage plate and the fourth corrugation of the second plate portion. At this time, the plate connection portion 71 of the drainage wire clamp can be arranged in the opening area of the drainage plate to connect the drainage wire clamp to the drainage plate.

[0091] In this implementation manner, by arranging the plate connection portion of the drainage wire clamp within the opening area to connect the drainage wire clamp and the drainage plate, not only the contact area between the drainage wire clamp and the drainage plate is increased, thus being able to alleviate the heating problem. At the same time, the installation difficulty of the strain clamp can also be reduced, and the installation convenience of the strain clamp can be improved, so that the strain clamp is convenient for installation and maintenance.

[0092] Based on the strain clamp provided by the above embodiment, it can be used to fix the wire. Specifically, among the strain clamps provided in the above embodiment, the drainage wire clamp is connected to the first wire, and the strain tube is connected to the second wire; power is conducted between the first wire and the second wire through the drainage wire clamp and the drainage plate.

[0093] In one example, the strain tube and the strain clamp may include a tubular structure capable of conducting electricity. For example, the strain tube may be an aluminum tube. As Figure 7 shown, the wire connection portion 72 of the drainage wire clamp may be an aluminum tube. At this time, the first wire can be fixed in the aluminum tube corresponding to the wire connection portion 72 of the drainage wire clamp, and the second wire can be fixed in the aluminum tube corresponding to the strain tube, so as to realize the connection between the first wire and the second wire.
