[0025] Embodiment 1:
[0026] like Figure 1-Figure 3 As shown, an embodiment of the utility model provides a dedicated wire clamp for live wires, comprising: a wire clamp body 1, a main line through hole 2, a through hole 3, a torque aluminum screw 4, an aluminum screw 5 and a pressure block 6. The main line through hole 2 is opened on the left side of the outer surface of the wire clamp body 1, and an incoming line channel is opened on the left side of the main line through hole 2, and a through hole 3 is opened on the right side of the outer surface of the wire clamp body 1. The torque aluminum screw 4 is threadedly arranged on the left side of the upper surface of the wire clamp body 1, and the through hole 3 is threadedly arranged on the right side of the wire clamp body 1. The torque aluminum screw 4 and the aluminum screw 5 are respectively inserted into the main line through hole 2 and the through hole 3, and a pressure block 6 is rotatably arranged at the bottom of the torque aluminum screw 4 and the aluminum screw 5.
[0027] When in use, the wire clamp body 1 is connected to the main line through the incoming line channel opened on the left side of the main line through hole 2, and the torque aluminum screw 4 is turned. The torque aluminum screw 4 drives the pressure block 6 to move downward, and cooperates with the bottom of the main line through hole 2 to clamp the main line, and then the lead wire is inserted into the through hole 3, and then the aluminum screw 5 is turned. The aluminum screw 5 drives the pressure block 6 to move downward, and cooperates with the bottom of the through hole 3 to press and hold the lead wire. The operation is simple and convenient, and the bottom of the pressure block is in an inverted "V" shape, so that when the pressure block 6 presses the main line and the lead wire, the main line and the lead wire will be embedded in the center of the inverted "V" shape at the bottom of the pressure block, which is convenient for pressing main lines and leads of different diameters.
[0028] In this embodiment, the upper parts of the main line through holes 2 and 3 are rectangular, and the lower parts of the main line through holes 2 and 3 are arc-shaped, which increases the contact area between the wire clamp and the wire and improves conductivity.
[0029] In this embodiment, two torque aluminum screws 4 and two aluminum screws 5 are provided, and the torque aluminum screws 4 and the aluminum screws 5 are respectively passed through the inner and outer ends of the main line through hole 2 and the through hole 3, so that when the main line or the lead is pressed, there are two pressing blocks 6 to press and increase stability.
[0030] In this embodiment, the width of the pressing block 6 is equal to the width above the main line through hole 2 and the through hole 3, which prevents the pressing block 6 from rotating with the torque aluminum screw 4 or the aluminum screw 5, thereby ensuring the stable lifting and lowering of the pressing block 6.
[0031] In this embodiment, the center of the bottom of the pressing block 6 is in an inverted "V" shape, and the bottom of the pressing block 6 is provided with anti-slip stripes, so that the pressing block 6 can press and hold cables of different diameters.
[0032] Example 2: Reference Figure 1-5 , which is different from the first embodiment in that:
[0033] In this embodiment, the pressing block 6 includes a track groove 601, a triangle 602, a track 603 and a spring 604. A track groove 601 is opened in the center of the bottom surface of the pressing block 6. Tracks 603 are slidably arranged on both sides of the track groove 601. The triangle 602 is fixedly arranged at the bottom of the track 603. Springs 604 are fixedly arranged between the two tracks 603 and the left and right sides of the track groove 601.
[0034] In this embodiment, the track groove 601 is matched with the track 603, and both the track groove 601 and the track 603 are in an inverted "convex" shape, which prevents the track 603 from escaping from the track groove 601 and can ensure the stability of the track 603 sliding left and right in the track groove 601.
[0035] In this embodiment, when the spring 604 is in a naturally stretched state, the two triangles 602 are in close contact with each other.
[0036] When the pressing block 6 presses the cable, the cable is between the two triangles 602. As the pressing block 6 moves downward, the two triangles 602 move in opposite directions, and the spring 604 is in a compressed state until the top of the cable contacts the bottom surface of the pressing block 6. The elastic force of the spring 604 causes the two triangles 602 to contact the side of the cable, so that the contact between the pressing block 6 and the cable changes from the original two-point contact to a three-point contact, thereby increasing the contact area between the cable and the pressing block 6 and increasing the conductivity of the wire clamp body 1 after installation.
