Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes, and particularly relates to a junction box convenient for wiring. Background Art

[0002] During the connection of power lines, in order to ensure the safety and normal use of the lines, a junction box is usually used as a transition at the joint of the wires. The junction box mainly plays the role of protecting the wires and connecting the wires.

[0003] The current junction box mainly consists of a box body, a box cover, a wiring row installed in the box body, and wiring heads installed on both sides of the wiring row on the box body. Although the junction box with the above structure can achieve the docking protection between wires during use, on the one hand, the overall structure of the junction box with the above structure is fixed, and it is impossible to store the redundant wires during wiring. On the other hand, when docking and fixing between two wires, external screwing tools need to be used to screw the two pressure screws respectively to achieve the pressing and fixing between the docking wires. Since the above screwing process is relatively cumbersome, the docking and installation efficiency between the two wires is relatively low, which is not convenient for the efficient docking and laying of wires. Content of the Utility Model

Two rows of wiring heads are symmetrically installed on both side walls of the box body. A winding component is installed above each of the wiring heads on the box body. A wiring row is installed in the middle of the bottom end of the box body. A mounting plate is installed above the wiring row in the box body.

The winding component includes a fixing plate installed on the box body, a winding column installed on one side of the upper end of the fixing plate, a limiting pressing plate installed on the fixing plate on one side of the winding column, and a spring rod installed between the limiting pressing plate and the fixing plate. The pressing component includes a screw rod installed on the mounting plate, a cross-shaped turning head installed at the top end of the screw rod, and a double-headed pressing plate installed at the bottom end of the screw rod.

[0008] Furthermore, a box cover is arranged on the upper side of the box body, and the box cover is connected to the box body by bolts.

[0009] By adopting the above technical solution, the box cover can shield and protect the wiring row in the box body after being fixed.

[0010] Furthermore, the fixing plate is an L-shaped structure, and the fixing plate is connected to the box body by bolts.

[0011] By adopting the above technical solution, it can be ensured that the fixing plate is reliably installed and fixed on the box body.

[0012] Furthermore, the spring rod is composed of a telescopic rod and a spring, and the fixed portion of the spring rod is bolted to the fixing plate, and the telescopic portion of the spring rod is bolted to the limiting pressure plate.

[0013] By adopting the above technical solution, the spring rod is mainly used to realize the convenient extension and retraction of the limiting pressure plate.

[0014] Furthermore, the length of the limiting pressure plate is shorter than the length of the winding post, and the limiting pressure plate is an arc-shaped concave structure facing the side wall of the winding post.

[0015] By adopting the above technical solution, after the limiting pressure plate is pressed on the winding post under the action of the spring rod, the electric wires on the winding post can be limited to avoid loosening.

[0016] Furthermore, the screw rod passes through the mounting plate and is threadedly connected to the mounting plate, the screw rods are distributed on the mounting plate at equal intervals, and the screw rods are rotationally connected to the double-head pressure plate.

[0017] By adopting the above technical solution, the screw rod can drive the double-headed pressing plate to press downward when it rotates and moves downward.

[0018] Furthermore, the cross swivel is welded to the screw rod, and the double-headed pressure plate is composed of a pressure plate and a pressure rod installed at the bottom end of the pressure plate, and the pressure rod on the double-headed pressure plate is slidably connected to the terminal block.

[0019] By adopting the above technical solution, the double-headed pressing plate can simultaneously press and limit the two butted wires after being pressed down.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] At present, the junction box mainly consists of a box body, a box cover, a wiring row installed in the box body, and wiring heads installed on both sides of the wiring row on the box body. Although the junction box with the above structure can achieve the docking protection between wires during use, during the wiring process, on the one hand, the overall structure of the junction box with the above structure is fixed and cannot accommodate the excess wires while wiring. On the other hand, when docking and fixing between two wires, an external screwing tool needs to be used to screw the two pressure screws respectively to achieve the pressing and fixing between the butt wires. Since the above screwing process is relatively cumbersome, the docking and installation efficiency between the two wires is relatively low, which is not convenient for the efficient docking and layout of wires. In the present utility model, a winding component is installed on the upper side of each wiring head, so that when wiring, the excess wires can be wound and accommodated by means of the winding column, and the fixed spring rod and the limit pressing plate are used to fix the wires after winding. At the same time, a pressing component is arranged on the upper side of each wiring hole of the wiring row in the box body, so that when docking and installing between two wires, the two wires can be synchronously pressed and fixed only by one screwing operation, and no external screwing tool is needed during screwing, so that the docking efficiency between the two wires is higher and it is convenient for the efficient docking and layout of wires.

The clamping assembly 6 includes a screw 603 installed on the mounting plate 2, a cross swivel 601 installed on the top of the screw 603, and a double-headed pressure plate 602 installed at the bottom of the screw 603. When the screw 603 rotates and moves downward under the action of the cross swivel 601, the double-headed pressure plate 602 can be driven to press down. After the double-headed pressure plate 602 is pressed down, the two connected wires can be simultaneously clamped and limited.

[0030] like Figures 1 - 3 As shown, in this embodiment, a box cover 1 is arranged on the upper side of the box body 5, and the box cover 1 is connected to the box body 5 by bolts. After the box cover 1 is fixed, it can shield and protect the wiring row 7 in the box body 5.

[0031] like Figures 1 - 3 As shown, in the present embodiment, the fixing plate 303 is an L-shaped structure, and the fixing plate 303 is bolted to the box body 5, which can ensure that the fixing plate 303 is reliably installed and fixed on the box body 5. The spring rod 304 is composed of a telescopic rod and a spring, and the fixing part of the spring rod 304 is bolted to the fixing plate 303, and the telescopic part of the spring rod 304 is bolted to the limiting pressure plate 302. The spring rod 304 is mainly used to realize the convenient extension and retraction of the limiting pressure plate 302. The length of the limiting pressure plate 302 is shorter than the length of the winding post 301. The limiting pressure plate 302 is an arc-shaped concave structure facing the side wall of the winding post 301. After the limiting pressure plate 302 is pressed on the winding post 301 under the action of the spring rod 304, the wires on the winding post 301 can be limited to avoid loosening.
