Description

Technical Field

[0001] This application relates to the field of wiring equipment technology, and in particular to a power distribution wiring device. Background Technology

[0002] Transformer and distribution wiring devices are crucial components in power systems, used to connect electrical equipment. Their stability and reliability directly affect the normal operation of the power system. In existing technologies, transformer and distribution wiring devices typically use bolts to connect terminals to other electrical equipment. While this method is simple and easy to operate, bolt fixation alone may not provide sufficient stability. Bolts can easily slip, leading to poor contact at the terminals and affecting normal current transmission. Therefore, a new transformer and distribution wiring device is proposed. Utility Model Content

[0005] A power distribution wiring device includes a base, a fixing bolt inserted at the center of the upper surface of the base, an annular plate sleeved around the fixing bolt, the inner diameter of the annular plate being larger than the outer diameter of the fixing bolt shank but smaller than the outer diameter of the fixing bolt head, multiple sets of insert rods fixedly connected to the surface of the annular plate, the insert rods being distributed in a circular array on the surface of the annular plate, and insertion holes being opened at positions on the upper surface of the base opposite to the insert rods, the insert rods being inserted into the corresponding insertion holes, and an elastic support mechanism being provided on one side of the annular plate, the elastic support mechanism positioning the insert rods above the insertion holes.

[0006] Preferably, the elastic support mechanism includes a connecting plate fixedly installed on one side of the annular plate, a vertical rod fixedly connected to the lower surface of the connecting plate away from the annular plate, the lower end of the vertical rod being slidably inserted into the base, a spring being sleeved on the outer surface of the vertical rod, the upper end of the spring being fixedly connected to the connecting plate, and the lower end of the spring being fixedly connected to the base.

[0007] Preferably, it also includes a cover body, which is disposed above the base, and connecting bolts are inserted at the four corners of the cover body, the ends of which can be screwed into the base.

[0008] Preferably, the cover is mounted outside the fixing bolts and the elastic support mechanism.

[0009] Preferably, arc-shaped plates are fixedly connected to both sides of the base and both sides of the cover. When the cover is connected to the base, the arc-shaped plates on the same side of the base and the cover form a sleeve structure.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] This utility model, by setting a plug rod to cooperate with the plug hole, when the fixing bolt moves down, the head of the fixing bolt drives the annular plate and the plug rod to move down, so that the plug rod is inserted into the corresponding plug hole. The plug rod can then further fix the wire wrapped around the fixing bolt and prevent the wire from slipping off the fixing bolt. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses a power distribution wiring device, including a base 1. A fixing bolt 5 is inserted at the center of the upper surface of the base 1. An annular plate 11 is sleeved on the outside of the fixing bolt 5. The inner diameter of the annular plate 11 is larger than the outer diameter of the rod of the fixing bolt 5 but smaller than the outer diameter of the head of the fixing bolt 5. Multiple sets of plug rods 10 are fixedly connected to the surface of the annular plate 11. The plug rods 10 are distributed in a ring array on the surface of the annular plate 11. A plug hole 6 is opened at the position opposite to the plug rod 10 on the upper surface of the base 1. The plug rod 10 is inserted into the corresponding plug hole 6. An elastic support mechanism is provided on one side of the annular plate 11. The elastic support mechanism makes the plug rod 10 located above the plug hole 6.

[0018] In this embodiment, the outer shells of the two sets of wire terminals to be connected are stripped off, and the wire terminals of the two sets of wire terminals with the outer shells stripped are wrapped around the bottom of the fixing bolt 5. Then, the fixing bolt 5 is rotated to move the fixing bolt 5 downward and fix the wires. In addition, during the downward movement of the fixing bolt 5, the head of the fixing bolt 5 drives the annular plate 11 and the plug rod 10 to move downward, so that the plug rod 10 is inserted into the corresponding plug hole 6. The plug rod 10 can further fix the wires wrapped around the fixing bolt 5 and prevent the wires from slipping off the fixing bolt 5.

[0019] In actual use, the base 1, fixing bolts 5, annular plate 11, and connecting plate 7 are all made of insulating materials to ensure safe use.

[0020] Furthermore, the elastic support mechanism includes a connecting plate 7 fixedly installed on one side of the annular plate 11. A vertical rod 9 is fixedly connected to the lower surface of the connecting plate 7 away from the annular plate 11. The lower end of the vertical rod 9 is slidably inserted into the base 1. A spring 8 is sleeved on the outer surface of the vertical rod 9. The upper end of the spring 8 is fixedly connected to the connecting plate 7, and the lower end of the spring 8 is fixedly connected to the base 1.

[0021] In this embodiment, the spring 8 is used to support the connecting plate 7 and the annular plate 11, so that the insertion rod 10 is located above the insertion hole 6, so that the wire can be wound around the fixing bolt 5. When the fixing bolt 5 is rotated and moved down, the annular plate 11 is moved down, the connecting plate 7 and the vertical rod 9 move down accordingly, and the spring 8 is compressed.

[0022] Furthermore, it also includes a cover 2, which is set above the base 1. Each of the four corners of the cover 2 is fitted with a connecting bolt 3, the end of which can be screwed into the base 1. The cover 2 covers the outside of the fixing bolt 5 and the elastic support mechanism.

[0023] In this embodiment, by providing a cover 2, the fixing bolts 5, the elastic support mechanism, and the wire connection part can be protected.

[0024] Furthermore, arc-shaped plates 4 are fixedly connected to both sides of the base 1 and both sides of the cover 2. When the cover 2 is connected to the base 1, the arc-shaped plates 4 on the same side of the base 1 and the cover 2 form a sleeve structure.

[0025] In this embodiment, the wire is placed inside the arc-shaped plate 4 between the mounting covers 2. After the covers 2 are installed, the arc-shaped plate 4 on the same side as the base 1 and the covers 2 form a sleeve structure that can fix the wire.
