Description

Technical Field

[0001] The utility model relates to the technical field of power lines, in particular to a connecting device for power lines. Background Art

[0002] The power cord is an electric wire that transmits electric current. Usually, the current is transmitted point to point. According to their use, power cords can be divided into AC power cords and DC power cords. Usually, AC power cords are wires that transmit alternating current with a higher voltage, and DC cords basically transmit direct current with a lower voltage. Power cords play a vital role in the use of home appliances. During the use of power cords, connections often appear between power cords to extend the conductive distance of the power cords.

[0003] In the prior art, the power cord is connected to the power cord by stripping out the metal wire inside the power cord, winding the two metal wires together, and then wrapping the two power cords with insulating tape. However, after a period of use, the viscosity of the tape will gradually weaken. As the power cord shakes, the power cord is easy to fall off, which may cause poor contact and easily cause circuit breakage, affecting the normal use of the power cord. Therefore, it is necessary to design a connection device for the power cord to solve the above problem. Utility Model Content

As the power cord shakes, the power cord is easy to fall off, which may cause poor contact, easily cause circuit breaking, and affect the normal use of the power cord, thereby achieving the technical effect of ensuring the stability of the two power cords and avoiding the situation of falling off. Since a technical means is adopted to position the power cord before clamping it, the first fixed plate will be driven to descend during the lowering of the upper shell, so that the roller can squeeze the trapezoidal plate to move the trapezoidal plate toward the direction of the power cord, and the trapezoidal plate will drive the positioning plate to move close to the power cord, so that the position of the power cord can be located, thereby achieving simple operation, facilitating the positioning of the power cord, avoiding unnecessary search time, and saving work time.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Reference Figure 1-Figure 3 A connection device for a power line comprises a lower shell 1, an upper shell 2 is arranged on the top of the lower shell 1, four first fixing plates 3 are fixedly connected to the inner wall of the top of the upper shell 2, the four first fixing plates 3 are all penetrated with rollers 4, the first fixing plates 3 are rotatably connected to the rollers 4, a trapezoidal plate 5 is arranged at the bottom of the rollers 4, the trapezoidal plate 5 is fixedly connected to a positioning plate 6 on the side away from the bevel, a plug plate 7 is arranged at the bottom of the positioning plate 6, the plug plate 7 is fixedly connected to the trapezoidal plate 5, the plug plate 7 is sleeved with a sleeve 8, the plug plate 7 is slidably connected to the sleeve 8, the sleeve 8 is fixedly connected to a square plate 9 on the side away from the trapezoidal plate 5, and the sleeve 8 and the plug plate 7 are sleeved with springs 10. Due to the use of a technical means for clamping and fixing two power boxes, the existing problems proposed in the background technology are effectively solved. The way of connecting the power cord is unstable. As the power cord shakes, the power cord is easy to fall off, which may cause poor contact and easily cause circuit breaking, affecting the normal use of the power cord, thereby achieving the technical effect of ensuring the stability of the two power cords and avoiding the situation of falling off. Since a technical means is adopted to position the power cord before clamping it, the first fixed plate will be driven to descend during the lowering of the upper shell, so that the roller can squeeze the trapezoidal plate to move the trapezoidal plate toward the direction of the power cord, and the trapezoidal plate will drive the positioning plate to move close to the power cord, so that the position of the power cord can be located, thereby achieving simple operation, facilitating the positioning of the power cord, avoiding unnecessary search time, and saving work time.

[0022] In this embodiment, a sealing gasket 13 is fixedly connected to the lower housing 1 and the upper housing 2 on one side close to each other.

[0023] In this embodiment, the inner walls at both ends of the lower shell 1 and the upper shell 2 are fixedly connected with support plates 14 , the support plates 14 are fixedly connected with clamping plates 11 , and the inner walls of the clamping plates 11 are fixedly connected with rubber pads 12 .

[0024] In this embodiment, two second fixed plates 15 are fixedly connected to the outer walls on both sides of the upper shell 2, and the bottom of the second fixed plate 15 is fixedly connected to a limiting rod 16, and the limiting rod 16 is sleeved with a sleeve plate 17, and the limiting rod 16 is slidably connected to the sleeve plate 17, and the sleeve plate 17 is fixedly connected to the lower shell 1, and the bottom of the sleeve plate 17 is fixedly connected to a baffle 18.

[0025] In this embodiment, both side outer walls of the lower housing 1 are fixedly connected with threaded sleeves 20 , and both end outer walls of the upper housing 2 are fixedly connected with mounting plates 19 .

[0026] In this embodiment, the inner wall of the mounting plate 19 is provided with bolts 21 , and the bolts 21 are matched with the threaded sleeves 20 .

[0027] Working principle: When using this device, one of the power cords can be placed between the two upper shells 2, and then the metal wires of the two power cords can be twisted together. Finally, the device can be moved to move the lower shell 1 and the upper shell 2 to the connection point of the metal wires of the two power cords, and the upper shell 2 can be pressed. The upper shell 2 will descend and drive the second fixing plate 15 to descend, and the second fixing plate 15 will drive the limiting rod 16 to move along the sleeve plate 17. Through the cooperation between the limiting rod 16 and the sleeve plate 17, the upper shell 2 will not deviate when moving, and the movement of the upper shell 2 will drive the first fixing plate 3 to move, and the first fixing plate 3 will drive the roller 4 to move. If the roller 4 continues to move after contacting the hypotenuse of the trapezoidal plate 5, the roller 4 will squeeze the trapezoidal plate 5, and the roller 4 will drive the trapezoidal plate 5 to move, and the trapezoidal plate 5 will drive the positioning plate 6 to move. If the positioning plate 6 continues to move after contacting the power cord, it can drive the power cord to move, and the power cord can be adjusted through the two positioning plates 6 at both ends. The positioning is corrected so that the power cord is placed between the rubber pads 12 at the top and bottom ends. After the roller 4 contacts the straight edge on the hypotenuse side of the trapezoidal plate 5, the power cord is between the rubber pads 12, and then the upper shell 2 descends to drive the support plate 14 to descend, and the support plate 14 will drive the clamping plate 11 to descend, and the clamping plate 11 will drive the rubber pad 12 to descend until the rubber pads 12 at the top and bottom ends contact the power cord, so that the two power cords can be clamped, which can prevent the position between the two power cords from being offset and falling off. At the same time, the two sealing pads 13 will also contact, with a certain degree of waterproofness. When the trapezoidal plate 5 moves, the trapezoidal plate 5 will also drive the plugging plate 7 to move, and the plugging plate 7 will move along the sleeve 8. The movement of the trapezoidal plate 5 will also squeeze the spring 10 to shrink the spring 10. After the two sealing pads 13 are in contact, the bolt 21 can be rotated to make the bolt 21 turn into the threaded sleeve 20, so that the position between the lower shell 1 and the upper shell 2 can be limited to prevent the lower shell 1 and the upper shell 2 from separating.
