Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to an electric power engineering wiring device. Background Art

[0002] Power engineering wiring devices are devices used to connect, protect, and control electrical wiring in power systems. They ensure the safe and efficient transmission and distribution of electrical energy. Common examples of power engineering wiring devices include junction boxes, terminal blocks, terminal blocks, and connectors.

[0003] A junction box is a wiring device used in power engineering to house and protect wire connection points. It's typically a box with a lid and contains multiple terminals or screws for securing and connecting wires. The primary function of a junction box is to protect the internal wire connection points from environmental factors such as moisture, dust, and mechanical damage. It also isolates the wire connection points to prevent electric shock and short circuits.

[0004] Before using a junction box for wiring, the wires need to be stripped (removed from the insulation) with a wire stripper. This exposes the conductor portion of the wire, allowing direct contact with the terminals or screws inside the junction box. However, existing junction boxes lack the ability to strip wires, requiring workers to use other tools to complete the process, which is inconvenient. While existing junction boxes allow for smooth wiring, the connectors on the junction boxes that connect to the wires lack external protection and are easily damaged by bumps and knocks. Furthermore, the wires connected to the connectors can easily fall off the junction box if pulled by external forces. To address this issue, we propose a wiring device for power engineering.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 - Figure 4 The figure shows an electric power engineering wiring device, comprising a junction box body 1 and four connectors 2 mounted on the junction box body 1. A square plate 3 is fixedly connected to the lower edge of the side wall of the junction box body 1. A cylindrical slot 4 is penetrated through the front end of the square plate 3, and a rectangular slot 18 is opened at the upper end of the square plate 3. The rectangular slot 18 is connected to the cylindrical slot 4, and a wire stripping knife 5 is attached to the inner wall of the rectangular slot 18. The upper end of the wire stripping knife 5 is fixedly connected to a connecting plate 6. A lifting assembly is provided between the connecting plate 6 and the junction box body 1. Concave plates 11 are symmetrically fixedly connected to the front and rear ends of the junction box body 1. The two concave plates 11 correspond to the positions of the two connectors 2 at the front and the two connectors 2 at the rear, respectively, and a threading mechanism is provided on both concave plates 11.

[0020] See also Figure 1 and Figure 3 In the figure, the lifting assembly includes a U-shaped plate 7, which is fixedly connected to the side wall of the junction box body 1 near the upper edge, and a screw 8 is screwed through the inner wall of the upper end of the U-shaped plate 7. The upper end of the screw 8 is provided with a rotating part, and the lower end of the screw 8 is rotatably connected to the upper end of the connecting plate 6, and a guide is provided between the connecting plate 6 and the U-shaped plate 7.

[0021] See also Figure 1 and Figure 3 In the figure, the rotating part includes a rotating block 9, which is fixedly connected to the upper end of the screw 8.

[0022] See also Figure 1 and Figure 3In the figure, the guide member includes a guide rod 10, which is fixedly connected to the upper end of the connecting plate 6 near the edge of the junction box body 1, and the upper end of the guide rod 10 is movable through the upper end of the U-shaped plate 7.

[0023] See also Figure 1 - Figure 2 In the figure, the threading mechanism includes two threading holes 12, and the two threading holes 12 are respectively opened at the front end of the concave plate 11 corresponding to the two connectors 2, and the inner walls of the two threading holes 12 are fitted with V-shaped plates 13 near the lower edge. The middle parts of the top ends of the two V-shaped plates 13 are fixedly connected with connecting columns 15. The upper ends of the two connecting columns 15 are movably passed through the upper end of the concave plate 11, and the upper ends of the two connecting columns 15 are jointly fixedly connected with a rectangular pull plate 14. The bottom end of the rectangular pull plate 14 and the upper end of the concave plate 11 are symmetrically fixedly connected with springs 16. The two springs 16 are slidably sleeved on the outer walls of the two connecting columns 15.

[0024] See also Figure 2 In the figure, the inner V-shaped surfaces of the two V-shaped plates 13 are fixedly connected with V-shaped rubber pads 17; specifically, the setting of the V-shaped rubber pads 17 can increase the friction between the wires, thereby making the wires clamped more firmly.

[0025] Working principle: When wire stripping is required before wiring, first rotate the rotating block 9 upward. The rotating block 9 will drive the screw 8 to rotate upward in the inner wall of the U-shaped plate 7, and the screw 8 will drive the connecting plate 6 to move upward (in this process, the screw 8 will also rotate on the connecting plate 6). The connecting plate 6 will drive the guide rod 10 to rotate upward in the inner wall of the U-shaped plate 7, and the connecting plate 6 will also drive the wire stripping knife 5 to slide upward in the rectangular groove 18 on the square plate 3. When the lower end of the wire stripping knife 5 is located above the cylindrical groove 4 on the square plate 3, the rotating block 9 can be stopped.

[0026] Then, pass one end of the wire through the cylindrical slot 4 so that the position where the wire needs to be stripped corresponds to the position of the wire stripping knife 5. Then, turn the rotating block 9 downward, and the wire stripping knife 5 will move down and cut the insulation layer of the wire. Then, hold the wire with one hand to keep it still, and hold and rotate the device with the other hand one circle. The wire stripping knife 5 will then cut the insulation layer of the wire in a circular manner. The insulation layer of the cut wire can then be removed from the wire. Then, follow the same operation to complete the stripping operation of the remaining wires. Similarly, when all wires are stripped, turn the rotating block 9 downward to reset the wire stripping knife 5 and put it in the storage state, avoiding the potential risks caused by the blade of the wire stripping knife 5 being exposed.

[0027] When the wire stripping is completed, the wiring operation can be carried out. When wiring, first pull the rectangular pull plate 14 at the front upwards. The rectangular pull plate 14 will drive the two connecting columns 15 on it to slide upwards in the inner wall of the concave plate 11 at the front (in this process, the two springs 16 between the rectangular pull plate 14 and the concave plate 11 will be stretched on the outer walls of their corresponding connecting columns 15). The two connecting columns 15 will drive their respective V-shaped plates 13 to move upwards in the wire threading holes 12 on their corresponding concave plates 11. Then, while keeping the rectangular pull plate 14 pulled, the two wires are inserted into the two wire threading holes 12 in turn and connected to the connectors 2 on their corresponding junction box bodies 1 (the wires are also located below the inner V-shaped surfaces of the V-shaped plates 13). Then, release the rectangular pull plate 14. Under the action of the two springs 16, the two V-shaped plates 13 will move downward, and the two wires can be clamped between the V-shaped rubber pads 17 on their corresponding V-shaped plates 13 and the wire threading holes 12. Similarly, the other two wires can be connected to the other two connectors 2 according to the same operation (and the other two wires will also be clamped between the V-shaped rubber pads 17 and the wire threading holes 12 on their corresponding V-shaped plates 13), which is easy to operate.

[0028] It should be noted that this wiring device does not require the staff to use other tools to strip the wires during wiring, which brings convenience to the staff. The two concave plates 11 not only provide external protection for the connector 2 on the wiring box body 1, reducing the possibility of the connector 2 being damaged by bumps, but also the threading mechanism on the concave plate 11 has the function of clamping the wires, reducing the possibility of the wires falling off from the wiring box when pulled by external force.
