DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-3 A line installation and connection device shown includes a fixing box 1 and a plurality of wiring ports a2 installed at the front end of the fixing box 1;

[0027] The rear end outer wall of the fixing box 1 is provided with wiring ports b8 near the left and right sides respectively;

[0028] The inner walls of the lower ends of the plurality of wiring ports a2 and wiring ports b8 are all threadedly connected with wiring terminals 3 to be fixed to the external circuits. First, the plastic skin of the input and output circuits is partially cut to leak out the copper wires in the circuits, and then the wiring terminals 3 in the wiring ports a2 and b8 are unscrewed, and then the copper wires in the input circuits are bent into arc shapes and put into the wiring ports b8 to be fixed by the wiring terminals 3. The copper wires in the output circuits are also bent and put into the wiring ports a2 to be fixed by the wiring terminals 3. The current input in the input circuits will disperse the current through the working elements inside the fixing box 1 and transmit it through the output circuits.

[0029] A plurality of fixing frames 13 are fixedly connected to the front end outer wall of the fixing box 1, a bottom pad 14 is fixedly connected to the lower end inner wall of the plurality of fixing frames 13, a clamping pad 15 is arranged inside the fixing frame 13 and on the upper side of the bottom pad 14, a threaded rod 17 is threadedly connected to the inner part of the upper end outer wall of the fixing frame 13 to drive the clamping pad 15 to move up and down under the action of external force, before the line is fixed, it passes through between the clamping pad 15 and the bottom pad 14 for fixing, and when the line is fixed, the threaded rod 17 is controlled to drive the clamping pad 15 to move downward to stably clamp the line on the bottom pad 14.

[0030] like Figure 6 and Figure 7 As shown, a threaded hole 18 that passes through from top to bottom is opened at the center of the upper outer wall of the fixed frame 13 to be screwed together with the threaded rod 17, a limiting plate 16 is fixedly connected between the upper outer wall of the clamping pad 15 and the lower outer wall of the threaded rod 17, a handle b19 is fixedly connected to the upper outer wall of the threaded rod 17 to drive the threaded rod 17 to rotate clockwise and counterclockwise under the action of external force, a through hole 20 with upper and lower openings is opened at the center of the upper outer wall of the limiting plate 16, a positioning groove 22 that passes through and is connected to the through hole 20 is opened at the center of the limiting plate 16, and a positioning plate 21 that is clamped in the positioning groove 22 is fixedly connected to the lower outer wall of the threaded rod 17.

[0031] When controlling the clamping pad 15 to move up and down, the threaded rod 17 is driven to rotate clockwise and counterclockwise by grasping the handle b19 to control the clamping pad 15 to move up and down. During the rotation of the threaded rod 17, the positioning plate 21 is driven to rotate in the positioning groove 22, thereby avoiding the situation where the limit plate 16 is driven to rotate.

[0032] like Figure 2 and Figure 4 As shown, a limiting groove 7 is arranged at the center of the outer wall of the right end of the fixed box 1 near the upper side, a guide column 11 is fixedly connected to the center of the inner wall of the lower end of the limiting groove 7, a pressure block 10 which is downwardly inserted into the limiting groove 7 is sleeved on the outside of the guide column 11, a handle a9 is fixedly connected to the center of the outer wall of the upper end of the pressure block 10 to control the pressure block 10 to move up and down in the limiting groove 7, a limiting hole 12 which opens downwards is arranged inside the center of the outer wall of the lower end of the pressure block 10 to abut and fix with the guide column 11, and the limiting groove 7 and the left side of the pressure block 10 are both arc-shaped.

[0033] When the copper wires in the input and output lines are bent, the pressing block 10 is first taken out of the limiting groove 7, and the copper wire can be placed in the limiting groove 7, and the copper wire is bent by abutting and controlling the copper wire and the guide column 11, so that the bending range of the copper wire can be smoother. After the bending is completed, the pressing block 10 is pressed downward in the limiting groove 7, so that the copper wire after bending can be flatter. When the pressing block 10 is pressed into the limiting groove 7, the pressing block 10 can be moved by pulling the handle a9 when it is taken out. The pressing block 10 can be taken out more quickly. When there is no need to bend the copper wire, the limiting hole 12 in the pressing block 10 and the guide column 11 can be plugged in to prevent the pressing block 10 from escaping from the limiting groove 7. The arc-shaped limiting groove 7 can assist in shaping the copper wire, making it more beautiful after bending. The circular outer wall of the guide column 11 and the circular inner wall of the limiting hole 12 fit together, so that the guide column 11 can be more accurately plugged into the limiting hole 12.

[0034] like Figure 1 As shown, the lowermost sides of the left and right outer walls of the fixed box 1 are fixedly connected to mounting plates 4, and fixing holes 6 are provided in the center of the upper outer walls of the two mounting plates 4 and close to the front and rear sides respectively, and the lower outer wall of the mounting plate 4 is fixedly connected to a base 5.

[0035] By moving the base 5 and the mounting plate 4 to the corresponding mounting position, the fixing holes 6 correspondingly provided on the mounting plate 4 and the base 5 can be passed through by external fixing screws to be fixedly connected to the mounting position.

[0036] The implementation principle of this embodiment is as follows: first, partially cut open the plastic skin of the input and output circuits to leak out the copper wires in the circuits, then unscrew the wiring terminals 3 in the wiring ports a2 and b8, then bend the copper wires in the input circuit into an arc shape under the restriction of the guide column 11 in the limit groove 7, and pass through between the clamping pad 15 and the bottom pad 14 and put into the wiring port b8 to be fixed by the wiring terminal 3, and similarly bend the copper wires in the output circuit and put into the wiring port a2 to be fixed by the wiring terminal 3, the current input in the input circuit will disperse the current through the working elements inside the fixing box 1 and transmit it through the output circuit, and after the circuit is fixed, the clamping pad 15 is moved downward by rotating the threaded rod 17, so that the circuit is clamped and fixed between the clamping pad 15 and the bottom pad 14.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
