[0026] The utility model provides a T-shaped wire clamp 100 .
[0027] See also Figure 1In one embodiment of the utility model, the T-shaped wire clamp 100 includes a clamping assembly 1 and three fasteners, wherein the clamping assembly 1 includes an upper clamp 11 and two lower clamps 12, wherein a first half groove 111 is provided on a side of the upper clamp 11 facing the lower clamp 12, and a second half groove 121 is provided on a side of the two lower clamps 12 facing the upper clamp 11, wherein the second half groove 121 is connected to the first half groove 111, and a third half groove 122 is provided on the opposite sides of the two lower clamps 12; wherein the two fasteners are respectively penetrated at the two ends of the upper clamp 11 and at one end of the two lower clamps 12 close to the upper clamp 11, and the other fastener is penetrated at one end of the two lower clamps 12 away from the upper clamp 11.
[0028] In the technical solution of the utility model, the main power line is accommodated in the first half groove 111 and the second half groove 121, and then the two fasteners are respectively passed through the two ends of the upper clamp 11 and the end of the two lower clamps 12 close to the upper clamp 11, the groove wall of the first half groove 111 and the groove wall of the second half groove 121 are enclosed to achieve the fixed installation of the main power line, and then the down conductor is accommodated in two connected third half grooves 122, and another fastener is passed through the end of the two lower clamps 12 away from the upper clamp 11, and the groove walls of the two third half grooves 122 are enclosed to achieve the fixed installation of the down conductor; this setting can make the main power line and the down conductor contact with the groove wall of the half groove, and the degree of fit between the groove wall and the conductor can be adjusted by adjusting the fastener, thereby increasing the contact area between the groove wall and the conductor while increasing the friction force, thereby improving the stability of the connection between the conductor and the wire clamp.
[0029] See also Figure 1 In one embodiment of the utility model, each lower clamp 12 includes a straight section 123 and a vertical section 124 connected to each other, the straight section 123 is provided with the second half groove 121, and the vertical section 124 is provided with the third half groove 122; wherein two fasteners are respectively provided at the two ends of the upper clamp 11 and the two straight sections 123, and another fastener is provided at the two vertical sections 124. The structure designed to connect the straight section 123 and the vertical section 124 can enhance the overall stability of the lower clamp 12, and such a design can provide more reliable support for the lower clamp 12 when it is subjected to wind force and external pressure, and reduce the possibility of deformation or failure caused by external force.
[0030] See also Figure 1In one embodiment of the utility model, each of the lower clamping member 12 further includes an inclined section 125, and the two ends of the inclined section 125 are respectively connected to the straight section 123 and the vertical section 124, and the two inclined sections 125 and the upper clamping member 11 enclose a receiving slot 126. A half slot may also be provided on the opposite side of the two inclined sections 125. The provision of the receiving slot 126 can ensure that the main power line and the down conductor have a certain distance during installation, providing a certain degree of insulation protection. When running at high load, the wires will generate a certain amount of heat. By maintaining a certain distance, the heat can be better dissipated to avoid safety problems caused by overheating. Maintaining a certain distance can also prevent mechanical collision or friction between the main power line and the down conductor, thereby reducing the possibility of accidental damage or failure. The provision of the receiving slot 126 can provide a certain degree of safety and reliability.
[0031] To improve the structural stability of the lower clamp 12, in one embodiment of the present invention, the angle between the vertical section 124 and the inclined section 125 is A, wherein 90°≤A≤135°. A larger angle can reduce the internal force concentration of the lower clamp 12, help disperse the effect of external forces, and can also enhance the overall structural stability of the lower clamp 12.
[0032] Further, in another embodiment of the present invention, A=135°. The larger the angle between the inclined section 125 and the vertical section 124 is, the stronger the bearing capacity and wind resistance of the connection part are, thereby improving the stability of the entire lower clamp 12 .
[0033] See also Figure 1 In one embodiment of the utility model, the two ends of the upper clamp 11 are formed with a first connection section 112, and the two ends of the two lower clamps 12 are respectively formed with a second connection section and a third connection section, wherein the two fasteners are respectively penetrated through the two first connection sections 112 and the two second connection sections, wherein the other fastener is penetrated through the two third connection sections. Providing the connection section can enhance the overall structural stability of the lower clamp 12 and the upper clamp 11, and the connection section provides additional support and connection points, making the connection between the two clamps more secure, thereby reducing the possibility of looseness and vibration; the connection section can also disperse the effect of external forces on the lower clamp 12 and the upper clamp 11, reducing the stress concentration of the connection part, which helps to improve the durability of the wire clamp and reduce material fatigue and damage caused by stress concentration.
[0034] See also Figure 1In one embodiment of the utility model, the T-type wire clamp 100 includes a plurality of the fasteners, and threaded holes 112a are provided on both sides of the first connection section 112, the second connection section, and the third connection section. The fasteners are usually bolts and nuts. The arrangement of multiple fasteners can disperse the stress between the connection points, thereby enhancing the stability of the overall structure. When subjected to external forces or vibrations, multiple connection points can share the load and reduce the possibility of single point failure. By increasing the number of connection points, the stress on each connection point can be reduced, thereby reducing the load on a single connection point and extending the service life.
[0035] See also Figure 1 In one embodiment of the utility model, both ends of each first connection section 112 are provided with arc transition sections 113. The arc transition sections 113 can effectively reduce the stress concentration at both ends of the connection section, thereby improving the stability and durability of the structure, because the arc transition section 113 can smoothly transition the shape of the connection section to the shape of the adjacent component, reducing the stress concentration caused by the sudden change; the arc transition section 113 makes the shape transition of the connection section smoother, which helps to improve the stability of the connection. To a certain extent, the arc transition section 113 can reduce the wind force borne by the connection section, thereby enhancing the bearing capacity of the connection.
[0036] In order to further improve the stability of the connection between the wire clamp and the wire, in one embodiment of the utility model, the groove wall of the first half groove 111, the groove wall of the second half groove 121, and the groove wall of the third half groove 122 are all provided with a plurality of convex ribs at intervals. The convex ribs can increase the rigidity of the groove wall, making it more resistant to external forces, thereby improving the stability of the overall structure. The presence of the convex ribs can disperse the stress to a larger surface area, reduce the possibility of local stress concentration, and help to extend the service life of the groove wall. The provision of the convex ribs can increase the connection stability between the wire and the groove wall.
[0037] See also Figure 2 In one embodiment of the utility model, the cross-sectional areas of the first half slot 111, the second half slot 121 and the third half slot 122 are gradually reduced from both ends to the middle. This configuration allows the T-shaped wire clamp 100 to adapt to wires of different diameters, and the user can select the corresponding installation position for wires of different diameters, thereby improving the applicability of the wire clamp.
