[0018] The following is a further detailed description of the present application in conjunction with the attached Figure 1 - attached Figure 3 to further illustrate the present application in detail.

[0019] The embodiment of the present application provides an integrated quick-installation strain string, which can be used to connect transmission cables, including an insulator string 10 and a strain clamp 20 fixedly connecting the cables. The two ends of the insulator string 10 are respectively fixedly connected with a first connecting member 11 for connecting the cross arm and a second connecting member 12 for connecting the strain clamp 20. The second connecting member 12 is connected to the strain clamp 20 through a connecting bolt.

[0020] The second connecting member 12 includes a fixed rod 13 fixedly connected to the insulator string 10. One end of the fixed rod 13 away from the insulator string 10 is hinged with a movable rod 14. The insulator string 10, the first connecting member 11 and the second connecting member 12 are integral prefabricated components. A locking hole 15 is formed in the movable rod 14, and the axis of the locking hole 15 does not coincide with the axis of the movable rod 14. The strain clamp 20 is provided with a positioning channel 21 through which the movable rod 14 can pass and a locking channel 22 for locking the movable rod 14. When the movable rod 14 is inserted into the positioning channel 21, the connecting bolt passes through the locking channel 22 and the locking hole 15 to realize the connection between the second connecting member 12 and the strain clamp 20.

[0021] The following is a further introduction in combination with a specific usage scenario.

[0022] In use, the operator uses a wire tightener to connect the cable to be connected and the cross arm. Subsequently, the strain string provided in the embodiment of the present application is lifted. First, it is connected to the cross arm using the first connecting member 11. Then, the strain clamp 20 is installed on the cable to be connected. After the installation is completed, the operator inserts the movable rod 14 of the second connecting member 12 into the positioning channel 21 of the strain clamp 20 until the locking hole 15 on the movable rod 14 coincides with the axis of the locking channel 22. Then, the operator can use a connecting bolt to connect the strain clamp 20 and the insulator string 10 into an integral body.

[0023] In the prior art, the entire strain string includes a suspension insulator equivalent to the insulator string 10 in the embodiment of the present application, a clamp equivalent to the strain clamp 20 in the embodiment of the present application, and fittings. In use, the operator also uses a wire tightener to connect the transmission cable and the pole tower. Subsequently, the operator uses connecting fittings to connect the suspension insulator and the clamp, thereby fixing the cable.

[0024] In the above-described prior art, first, look at the connection process between the suspension insulator and the pole tower. In this connection process, first, the connection head of the suspension insulator needs to be inserted into the fitting, and then a tool such as a hammer is used to knock the M pin into the fitting to achieve the connection between the suspension insulator and the fitting. Subsequently, the operator installs the fitting on the pole tower to achieve the connection between the suspension insulator and the pole tower. In this process, three steps are required. In the embodiment of the present application, the first connecting member 11 for connecting to the pole tower is directly fixed on the insulator string 10, and there is no need for the operator to connect the first connecting member 11 and the insulator string 10 on site, reducing two installation steps for the operator.

[0025] Next, look at the connection between the suspension insulator and the clamp in the prior art. In the prior art, the suspension insulator and the clamp are also connected through fittings. During this connection process, first, the connection head of the suspension insulator needs to be inserted into the fitting, and tools such as a hammer are used to knock the M-pin into the fitting to achieve the connection between the suspension insulator and the fitting. Then, the connection head of the fitting is aligned with the connection part of the clamp, and bolts are used to connect and fix the fitting and the clamp. Especially when connecting the fitting installed on the suspension insulator to the clamp, the operator needs to manually support the relatively heavy suspension insulator, control the connection head of the fitting on the suspension insulator to align with the connection hole on the clamp and keep the position relatively unchanged, so as to insert and connect the stud. Generally speaking, it consists of five steps: the positioning step between the fitting and the suspension insulator, the fixing step between the fitting and the suspension insulator, the positioning step between the fitting and the clamp, the position-keeping step between the fitting and the clamp, and the fixing step between the fitting and the clamp. In the embodiment of the present application, the second connecting member 12 and the insulator string 10 are prefabricated components. The fixing rod 13 is directly fixed on the insulator string 10, and the movable rod 14 is directly hinged on the fixing rod 13, omitting two steps of installing the electrical fitting on the insulator string 10. When the insulator string 10 is connected to the strain clamp 20, the operator only needs to insert the movable rod 14 into the positioning channel 21 on the strain clamp 20. After the end of the movable rod 14 contacts the inner wall at the end of the positioning channel 21, the positioning is completed. After the operator inserts the connection stud into the locking channel 22 and the locking hole 15 of the movable rod 14, the connection can be completed. Compared with the prior art, the embodiment of the present application omits two steps of connecting between the insulator string 10 and the electrical fitting when realizing the connection between the strain clamp 20 and the insulator string 10, reducing the difficulty of positioning and position-keeping between the strain clamp 20 and the insulator string 10. Generally, it reduces the steps and time for the operator to install the strain string, improving the work efficiency.

[0026] Generally speaking, in the embodiment of the present application, by integrating the electrical fitting into the insulator string 10 and optimizing the connection relationship between the insulator string 10 and the strain clamp 20, the steps required for the operator to install the entire strain string are reduced, and the installation efficiency of the strain string is improved.

[0027] The first connecting member 11 is used to connect to the tower. In some possible implementation manners of the embodiment of the present application, the first connecting member 11 may include a connecting rod and a hanging ring fixedly connected to the connecting rod.

[0028] The positioning can be achieved by inserting the movable rod 14 of the second connecting member 12 into the positioning channel 21 of the strain clamp 20. The operator can install it by passing a bolt through the locking channel 22 of the strain clamp 20 and the locking hole 15 of the movable rod 14. In the embodiment of the present application, the angle between the axis of the locking hole 15 and the axis of the movable rod 14 can be an acute angle or a right angle. When the angle between the axis of the locking hole 15 and the axis of the movable rod 14 is an acute angle, the contact area between the inner wall of the locking hole 15 of the movable rod 14 and the connecting bolt is large, which can improve the stability and firmness of the connection between the movable rod 14 and the strain clamp 20. When the angle between the axis of the locking hole 15 and the axis of the movable rod 14 is a right angle, it is convenient for the operator to install and the installation efficiency is high.

[0029] The positioning channel 21 is located on the strain clamp 20. In actual use, a locking member 23 is fixedly connected to the strain clamp 20. Both the positioning channel 21 and the locking channel 22 are opened on the locking member 23. The locking member 23 is fixedly connected to one side of the strain clamp 20, which enables the end of the stud to easily engage in threaded cooperation with the nut after passing through the locking hole 15 and the locking channel 22 without interfering with the fixing of the cable.

[0030] In a feasible specific implementation manner of the embodiment of the present application, the cross-sections of both the movable rod 14 and the positioning channel 21 are rectangular. In this way, after the movable rod 14 is inserted into the positioning channel 21, the probability of the axial rotation of the movable rod 14 relative to the positioning channel 21 can be reduced, so that the locking hole 15 of the movable rod 14 can be more stably aligned with the locking channel 22, reducing the difficulty for the operator to maintain the positional relationship between the strain clamp 20 and the insulator string 10 and improving the work efficiency.

[0031] In a feasible specific implementation manner of the embodiment of the present application, the end edge of the movable rod 14 away from the insulator string 10 is chamfered. The chamfer of the end edge of the movable rod 14 can play a guiding role during the insertion into the positioning channel 21, reducing the time for the operator to insert the movable rod 14 into the positioning channel 21 and improving the work efficiency.

[0032] The embodiments of this specific implementation manner are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
