Description

Technical Field

[0001] The utility model relates to the technical field of bus duct plug-in boxes, in particular to a bus duct plug-in box. Background Art

[0002] In many scenarios of power distribution, bus duct plug-in boxes are key nodes for power transmission, and their performance is crucial. However, current bus duct plug-in boxes have significant deficiencies in temporary power supply functions. In terms of temporary power supply functions, traditional bus duct plug-in boxes are difficult to quickly and conveniently adapt to the diverse needs of different temporary power supply scenarios. For example, in some temporary construction sites, emergency rescue sites or temporary activity venues, the power and voltage requirements of electrical equipment are different, and the power supply time and location are uncertain. However, the existing bus duct plug-in boxes lack a flexible adjustment mechanism and cannot quickly adjust the power output parameters according to actual conditions, resulting in an unstable and inefficient supply of temporary power supply, affecting the progress of work or the smooth progress of activities.

[0003] At the same time, there are many problems in the fixation and protection of wires. The wires connected to the bus duct plug-in box may be interfered with by various external factors in a temporary use environment. Due to the lack of effective fixing measures, the wires are easily pulled and collided during the movement of people and equipment, resulting in displacement or even falling off. This will not only interrupt power transmission, but may also cause safety hazards to surrounding personnel and equipment. Moreover, the existing protection measures are not sufficient to cope with complex and changeable temporary environments, such as wet ground and dusty spaces. The wires are easily corroded, the insulation performance degrades, and aging is accelerated, which in turn affects the quality and safety of power transmission and shortens the service life of the wires and plug-in boxes.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0025] See also Figure 1-6 The utility model provides a technical solution: a bus duct plug-in box, including a box body 1 and a door panel 2. The front surface of the box body 1 is provided with a door panel 2, and the top inner surface of the box body 1 is provided with a connector 3, which can be inserted into the bus duct to transmit electricity to the switch unit 4. The bottom end of the connector 3 is provided with a switch unit 4, and the connector 3 at the top is connected to control the power switch at the same time.

[0026] The front surface of the switch unit 4 is connected to a special-shaped copper sheet 5, and the top is connected to the switch unit 4. At the same time, due to the tapping column 6 set on the front surface of the special-shaped copper sheet 5, temporary electricity can be connected to the tapping column 6, thereby realizing temporary electricity use in a small range around the plug-in box. The front surface of the special-shaped copper sheet 5 is provided with a tapping assembly, which cooperates with the special-shaped copper sheet 5 to enable electricity to be tapped, thereby realizing temporary electricity use in a small range around the plug-in box. A protective seat 8 is provided on the back of the special-shaped copper sheet 5 for protecting and fixing the special-shaped copper sheet 5. A protective cover 9 is provided at the bottom end of the protective seat 8 for protecting the part where the bottom end of the special-shaped copper sheet 5 is connected to the external wires. A through hole 10 is provided at the bottom end of the box body 1 for the passage of wires. Fixings 11 are provided on both sides of the bottom end of the box body 1 for fixing the wire locking assembly at the bottom. The bottom end of the fixing 11 is provided with a wire locking assembly, which can lock the wires to prevent damage to the wires due to dragging, thereby causing power outages.

[0027] The tapping assembly includes a tapping post 6, which is used to tap out electricity so as to achieve temporary power supply within a small range of the plug-in box. The tapping post 6 is arranged on the front surface of the special-shaped copper sheet 5. The outer wall of the tapping post 6 is provided with an insulating sleeve 7 to avoid direct contact between the tapped wires and the special-shaped copper sheet 5, thereby preventing mixing of electricity or short circuit of electricity. Fixed frames are provided on the left and right sides of the protective seat 8, and the fixed frames are connected to the protective cover 9. The protective cover 9 can be swung in and out with the fixed frame as the center to ensure that the protective cover 9 can be opened and closed. The bottom end of the special-shaped copper sheet 5 is provided with a through hole for connecting the wires to facilitate the connection of the wires.

[0028] The wire lock assembly includes a connector 12, which is arranged at the bottom end of the fixing member 11 and is used to connect the fixing member 11 and the swinging member 13. The bottom end of the connector 12 is provided with a swinging member 13, which can swing to control the rubber strip 14 at the bottom end. The bottom end of the swinging member 13 is provided with two rubber strips 14. When the two rubber strips 14 are clamped, the wires can be locked to prevent the wires from being damaged due to dragging. The left and right sides of the rubber strip 14 on the front surface are provided with grooves 15 for limiting the sliding position of the sliding member 17 and loading the sliding member 17 at the same time. The left and right sides of the rubber strip 14 on the back are provided with plastic buckles 16. When the sliding member 17 slides to the plastic buckle 16 When the wires are in contact with each other, the sliding member 17 can be stuck. The sliding member 17 is provided inside the slide groove 15, and the rubber strip 14 is controlled by the slide groove 15 and the plastic buckle 16 to lock and unlock the wires. The bottom end of the connector 12 is provided with a through hole. The swinging member 13 is connected to the connector 12 by a pin to ensure that the swinging member 13 can swing. There is a gap between the two rubber strips 14, and the side of the rubber strip 14 close to the gap is made of soft rubber material. Soft rubber can be more easily plasticized, so that the contact area between the rubber strip 14 and the wire is larger and the friction generated is also greater. The side of the rubber strip 14 away from the gap is made of hard plastic material. Hard plastic can make the rubber strip 14 clamp the wire more tightly.

[0029] The sliding member 17 can slide left and right inside the slide groove 15. When the sliding member 17 slides to the innermost side of the slide groove 15, it can be clamped by the plastic buckle 16. The sliding member 17 cooperates with the slide groove 15 and the plastic buckle 16 to control the rubber strip 14.

[0030] Working principle: When temporary electricity is needed around the bus duct plug-in box, it is necessary to first disconnect the connection between the wires and the switch 4, and then fix the special-shaped copper sheet 5 at the corresponding position of the protective seat 8, and then connect the special-shaped copper sheet 5 to the switch 4. After the connection, fix the protective seat 8 on the inner wall of the box body 1, and then open it by shifting the protective cover 9. In this way, the bottom end of the special-shaped copper sheet 5 can be connected to the wires again, and the tap wires can be connected to the tap column 6. In this way, the tap wires can be connected to the electrical appliances around the plug-in box for use.

[0031] After the wires are connected to the bus duct junction box, the fixing member 11 can be fixed to the bottom end of the box body 1 first, and then the sliding member 17 can be slid outward to release the lock between the slide groove 15 and the plastic buckle 16. At this time, the swing member 13 can control the gap between the rubber strips 14, so that the wires can pass through the through hole 10 and then through the gap between the rubber strips 14. After passing through, the sliding member 17 is pushed inward. When the sliding member 17 slides to the innermost side of the slide groove 15, it will be stuck by the plastic buckle 16, thereby locking the rubber strip 14. Due to the locking of the rubber strip 14, the wires are also clamped, thereby preventing damage to the wires due to dragging.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
