DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the power cable connection assembly has a hard insulating shell 1, and several shells 1 are arranged and fixed for connecting several lines. A line port 11 is opened on the left side of the shell 1. The fixed wheel 2, the conductor wheel 4, and the moving wheel 3 are all arranged in the shell 1. The fixed wheel 2 and the moving wheel 3 are made of insulating materials. The surface of the conductor wheel 4 has a metal copper layer. The fixed wheel 2 and the moving wheel 3 are distributed on the left and right. The conductor wheel 4 is located above the fixed wheel 2 and the moving wheel 3. Slide grooves are symmetrically opened on both sides of the inner wall of the shell 1. The slider is elastically installed in the slide groove by a spring. The shaft end of the moving wheel 3 is rotatably connected with the slider. The moving wheel 3 can be moved left and right by the guidance of the slider, and the elastic force of the spring makes the moving wheel 3 have a tendency to approach the fixed wheel 2. The axis of the fixed wheel 2 and the axis of the conductor wheel 4, and the axis of the conductor wheel 4 and the axis of the moving wheel 3 are rotatably connected in sequence through a connecting rod 5; like Figure 1 , Figure 2 , Figure 5 As shown, the pressing assembly includes two swing arms 7, which are symmetrically rotatably mounted on both sides of the housing 1. An arc groove 74 is formed through the side of the housing 1. A pressure rod 71 passes through the arc groove 74 and is connected to the swing arm 7. The pressure rod 71 presses the surface. A sliding groove is formed on the surface of the swing arm 7 at the top of the conductor wheel 4. The movable inclined block 72 slides on the surface of the swing arm 7 through the elasticity of a spring, and a fixed inclined block 73 is fixed on the side of the housing 1. A conductive terminal 6 is fixedly arranged at the bottom of the housing 1, and the conductive terminal 6 is led out from the right end of the housing 1; The conductive terminal 6 is connected to the power facilities of the distribution cabinet, the end of the cable is peeled to expose the battery core, the battery core at the end of the cable is inserted into the housing 1 through the wire port 11, and the battery core is inserted between the fixed wheel 2, the moving wheel 3, and the conductor wheel 4. The fixed wheel 2 and the moving wheel 3 are located below the battery core, and the conductor wheel 4 is located above the battery core. Then the swing arm 7 is swung downward to make the pressure rod 71 move downward along the arc groove 74, the pressure rod 71 presses the conductor wheel 4 downward, and the conductor wheel 4 is rotated around the fixed wheel 2 through the connecting rod 5. At the same time, the moving wheel 3 is pushed to the right through the connecting rod 5 to expand the spacing between the fixed wheel 2 and the moving wheel 3, so that the conductor wheel 4 moves through the fixed wheel 2 and the moving wheel 3. The conductor wheel 4 presses the battery core downward, and the fixed wheel 2 and the moving wheel 3 contact to cover the battery core and fit it to the outside of the conductor wheel 4. The cable is clamped in a continuously curved shape. At this time, the conductor wheel 4 descends to squeeze the battery core to fit with the conductive terminal 6, and the cable is connected to the circuit through the conductive terminal 6; When the swing arm 7 is in the downward swinging process, the movable bevel block 72 and the fixed bevel block 73 are in contact with each other, so that the movable bevel block 72 elastically slides over the fixed bevel block 73, and the fixed bevel block 73 is in contact with the movable bevel block 72, so as to prevent the swing arm 7 from swinging in the opposite direction, so that the pressure rod 71 can stably keep pressing down on the conductor wheel 4. When removing the cable, it is necessary to manually slide the movable bevel block 72 out of contact with the fixed bevel block 73, and then swing the swing arm 7 upward to release the conductor wheel 4.

[0022] like Figure 3 , Figure 4 , Figure 6 As shown, the surfaces of the fixed wheel 2, the conductor wheel 4, and the moving wheel 3 are all provided with grooves adapted to the cable cores, so that the fixed wheel 2, the conductor wheel 4, and the moving wheel 3 can stably buckle the cores, keep the cores fixed while preventing the cores from being damaged by excessive squeezing, and the conductive terminal 6 has an arc portion 61 that fits the conductor wheel 4, and the conductor wheel 4 squeezes the cable to fit with the arc portion 61 to maintain an effective conductive area. When the conductor wheel 4 squeezes the cable to fit with the arc portion 61, the center position of the conductor wheel 4 is lower than the center position of the fixed wheel 2 and the moving wheel 3, and an elastic squeezing force is exerted by the moving wheel 3 toward the fixed wheel 2, which generates downward pressure on the conductor wheel 4, so that the conductor wheel 4 maintains a stable position and can stably lock the bent cable.

[0023] like Figure 3 , Figure 4 As shown, the end of the connecting rod 5 has a movable groove 51, the axial end of the conductor wheel 4 penetrates into the movable groove 51, the fixed wheel 2 is rotatably connected to the bracket 21, and a stud 22 is threadedly penetrated on the left side of the housing 1, and the stud 22 is rotatably connected to the bracket 21; The movable groove 51 is provided so that there is a movable gap between the conductor wheel 4 and the fixed wheel 2 and the moving wheel 3. When the cable is inserted into the housing 1 in a straight line, the conductor wheel 4 can jump upward. During the descending process of the conductor wheel 4, the gap between the conductor wheel 4 and the fixed wheel 2 and the moving wheel 3 is reduced, which is used to clamp the cable. When removing the cable connection, the stud 22 can be rotated to push the bracket 21 and the fixed wheel 2 to move toward the left end of the housing 1, thereby releasing the clamping of the cable and facilitating the extraction of the cable.

[0024] like Figure 1 As shown, a carrier 8 is vertically elastically slidably provided on the surface of the shell 1, a rubber pressing block 81 for aligning the line port 11 is fixed on the surface of the carrier 8, a boss 82 is fixed at the bottom of the carrier 8, and the boss 82 contacts the bottom surface of the swing arm 7. When the cable is connected, after the end of the cable is inserted into the shell 1, the position where the cable contacts the line port 11 is not exposed, the swing arm 7 swings down to squeeze the boss 82, and the carrier 8 descends, so that the rubber pressing block 81 presses the cable in the line port 11, further tightening the cable connection.

[0025] The above-mentioned power cable connection assembly is applied to the line output and input of the distribution cabinet and the line connection of electrical components.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
