Description

Technical Field

[0001] This utility model relates to the field of power distribution networks, and in particular to a line connection device for power distribution networks. Background Technology

[0002] The power distribution network is a crucial component of the power system, responsible for stepping down and distributing high-voltage electricity transmitted from the transmission network to end users such as homes, commercial buildings, and industrial facilities. It includes substations, distribution lines, transformers, switchgear, and various protection devices. In existing power distribution network systems, due to the frequent plugging and unplugging of plugs and sockets, these connections often loosen over time, leading to poor contact or even accidental disconnection. This not only severely impacts the reliability and security of power supply but can also result in economic losses such as equipment damage, power outages, and increased maintenance costs.

[0003] Therefore, it is necessary to design a line connection device for power distribution networks to solve the above-mentioned technical problems. Utility Model Content

[0004] In order to overcome the disadvantage that the connection points gradually become loose over time, resulting in poor contact, the technical problem of this utility model is to provide a line connection device for power distribution networks.

[0005] The technical implementation scheme of this utility model is as follows: A line connection device for power distribution network includes a housing, a connection socket, a transmission line, a support column, a buckle, a connecting frame, a pulley, and a second spring. Connection sockets are provided on both the left and right sides of the inner side of the housing. A transmission line is fixedly connected between the connection sockets on both sides, and the transmission line is electrically connected to the two connection sockets. Multiple support columns are fixedly connected to both the left and right sides of the middle of the housing. The number of support columns is equal to and corresponds to the number of connection sockets. The support columns on the left and right sides are symmetrical. Two buckles are fixedly connected to the upper part of each support column. A connecting frame is slidably connected to the upper part of each support column. A pulley is fixedly connected to the end of each connecting frame away from the center. The connecting frames and pulleys on the left and right sides of the housing are symmetrical. A second spring is fixedly connected between the connecting frame and the support column.

[0006] Furthermore, it also includes mounting blocks, snap-fit ​​blocks, wedge blocks, a first spring, and a push rod. Multiple mounting blocks are fixedly connected to the top left and right sides of the housing. The number of mounting blocks is equal to and corresponds to the number of sockets in the connection socket. Snap-fit ​​blocks are slidably connected to the front and rear sides of each mounting block. Wedge blocks are fixedly connected to the top of each snap-fit ​​block. The two wedge blocks are symmetrical. A first spring is fixedly connected between each snap-fit ​​block and the mounting block. A push rod is slidably connected to the right side of the mounting block, and the push rod contacts the wedge block.

[0007] Furthermore, it also includes placement frames and transparent plates. Multiple placement frames are fixedly connected to both the left and right sides of the housing. The number of placement frames is equal to and corresponds to the number of sockets on the connection socket. Each placement frame is electrically connected to the corresponding socket on the connection socket. A transparent plate is fixedly connected to the side of each placement frame away from the center.

[0008] Furthermore, it also includes a pull rod, with a pull rod slidably connected to the front side of each placement box.

[0009] Furthermore, it also includes supplementary lights, with each placement frame having a supplementary light fixedly connected to its bottom. The placement frames on the left and right sides are symmetrical, and the corresponding supplementary lights and placement frames are electrically connected.

[0010] Furthermore, it also includes an insulating sleeve, with an insulating sleeve fixedly connected to the top of each mounting block.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model, through the cooperation of the connecting socket, buckle, second spring and pulley, prevents workers from accidentally pulling the plug cord, thereby affecting the plug and causing the plug and connection point to gradually become loose, have poor contact and be accidentally pulled out over time.

[0012] 2. This utility model uses the cooperation of a snap-fit ​​block, a wedge block, and a push rod to clamp the plug and prevent it from becoming loose.

[0013] 3. This utility model uses a transparent plate and supplementary lighting to display the use of the power card, and makes it convenient for staff to view the information on the power card.

[0014] 4. This utility model has excellent electrical performance through the insulating sleeve, which can effectively prevent power outage accidents caused by human contact. Attached Figure Description

Detailed Implementation

[0021] Example: A line connection device for a power distribution network, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the device includes a housing 1, a connecting socket 2, a power transmission line 3, a support column 13, a buckle 14, a connecting frame 15, and a second spring 16. Connecting sockets 2 are provided on both the left and right sides of the inner side of the housing 1. A power transmission line 3 is fixedly connected between the two connecting sockets 2 on both sides. The power transmission line 3 is electrically connected to the two connecting sockets 2. Multiple support columns 13 are fixedly connected to both the left and right sides of the middle part of the housing 1. The number of support columns 13 is equal to and corresponds to the number of sockets in the connecting socket 2. The support columns 13 on the left and right sides are symmetrical. Two buckles 14 are fixedly connected to the upper part of each support column 13. A connecting frame 15 is slidably connected to the upper part of each support column 13. A pulley 17 is fixedly connected to the end of each connecting frame 15 away from the center. The connecting frames 15 and pulleys 17 on the left and right sides of the housing 1 are symmetrical. A second spring 16 is fixedly connected between the connecting frame 15 and the support column 13.

[0022] like Figure 2 and Figure 3 As shown, it also includes mounting blocks 4, snap-fit ​​blocks 5, wedge blocks 6, first springs 7 and push rods 8. Multiple mounting blocks 4 are fixedly connected to the top left and right sides of the housing 1. The number of mounting blocks 4 is equal to and corresponds to the number of sockets in the connection socket 2. Snap-fit ​​blocks 5 are slidably connected to the front and rear sides of each mounting block 4. Wedge blocks 6 are fixedly connected to the top of each of the two snap-fit ​​blocks 5. The two wedge blocks 6 are symmetrical. The first spring 7 is fixedly connected between each of the two snap-fit ​​blocks 5 and the mounting block 4. Push rods 8 are slidably connected to the right side of the mounting block 4. Push rods 8 are in contact with wedge blocks 6.

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a placement frame 9 and a transparent plate 10. Multiple placement frames 9 are installed on both the left and right sides of the housing 1. The number of placement frames 9 is equal to and corresponds to the number of sockets on the connecting socket 2. Each placement frame 9 is electrically connected to the corresponding socket on the connecting socket 2. A transparent plate 10 is fixedly connected to the side of each placement frame 9 away from the center end.

[0024] like Figure 5 As shown, it also includes a pull rod 11, and each placement frame 9 is slidably connected to the front side of the pull rod 11.

[0025] like Figure 5 As shown, it also includes a fill light 12. Each placement frame 9 is equipped with a fill light 12 at its bottom. The placement frames 9 on the left and right sides are symmetrical, and the corresponding fill lights 12 and placement frames 9 are electrically connected.

[0026] like Figure 1 As shown, it also includes an insulating sleeve 18, with an insulating sleeve 18 installed on the top of each mounting block 4.

[0027] When this device is needed for power distribution, first, insert the plug cord that needs to be energized into the upper latch 14, then connect the energized plug cord to the pulley 17, and then insert it into the lower latch 14. Press the push rod 8 towards the center, thereby causing the wedge block 6 to move the locking block 5 away from the center, compressing the first spring 7. Then, insert the energized plug into the connector socket 2, release the push rod 8, and the first spring 7 extends, causing the locking block 5 to move towards the center, locking the plug. If the operator accidentally pulls the plug cord, the pulling force will cause the pulley 17 to rotate clockwise, moving the connecting bracket 15 towards the support column 13, which will compress the second spring 16 to prevent the pulling force from affecting the plug. When the plug cord is no longer pulled, the second spring 16 will release. Spring 16 extends and drives connecting bracket 15 to reset, while pulley 17 rotates counterclockwise to adjust plug cable. This plugging method prevents plug and connection points from gradually becoming loose, having poor contact, or being accidentally pulled out over time. This device is equipped with multiple sockets, making it convenient for staff to use multiple devices that require power. Then, insert the power card into the corresponding placement frame 9. After inserting the power card, the supplementary light 12 is activated to emit light. Because each placement frame 9 is equipped with a transparent plate 10, staff can easily view the information on the power card. Each mounting block 4 is equipped with an insulating sleeve 18 on top, which has excellent electrical performance and can effectively prevent power outages caused by human contact. If power distribution is still required, the above operation can be performed again.

[0028] To unplug the plug and cancel the power distribution, first pull the lever 11 upwards to move the power-on clip upwards and remove the power supply. Release the lever 11 to reset it. Then, disconnect the plug wire from the two clips 14. Next, press the push rod 8 towards the center end to remove the plug from the jamming. Then you can unplug the plug. After unplugging the plug, release the push rod 8. The first spring 7 extends and drives the locking block 5 and the push rod 8 to reset.
