Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer lead-out wire structure. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The transformer lead wires are generally located outside the transformer windings. The transformer output voltage can be transmitted to other electrical equipment or circuits through the lead wires, realizing the transmission and control of electrical energy.

[0003] The existing lead-out wire structure can play a role in combing the wires to prevent multiple wires from being entangled together. For example, Chinese patent application number CN202322078441.0 discloses a transformer lead-out wire structure, including a base plate, a support plate fixedly connected to one side of the top of the base plate, three support grooves are opened on the top of the support plate, two stabilizing rods are fixedly embedded in the top of the base plate, and a fixing device is fixedly connected to the top of the base plate; the fixing device includes an installation box.

[0004] This structure fixes the wire through a circular hole. The circular hole is directly opened on the installation box, and the position of the circular hole on the installation box is fixed, so the wire can only be limited by passing through the circular hole, making this structure difficult to use for the already installed lead wire.

[0015] Beneficial effects

[0016] The utility model provides a transformer lead wire structure, which has the following beneficial effects:

[0017] By setting up the upper shell, lower shell and other structures, due to the rotational connection between the upper shell and the lower shell, the upper shell and the lower shell can be opened, and then multiple slots can be clamped on the corresponding wires. The upper and lower shells and the upper shell are closed and connected and fixed, so that the wires can be limited to prevent multiple wires from being entangled together.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 1-5 The utility model provides a technical solution: a transformer lead-out structure, including an upper shell 1, one side of the lower surface of the upper shell 1 is rotatably connected to the lower shell 2 through a rotating shaft, a plurality of slots 3 are provided on each side of the upper shell 1 and the lower shell 2, a spring 4 is longitudinally connected to the upper surface of the upper shell 1, the upper end of the spring 4 is connected to a connecting plate 5, the lower surface of the connecting plate 5 is connected to a plurality of limit plates 7 through a plurality of fixing plates 6, a plurality of through-holes 8 corresponding to the positions of the limit plates 7 are opened on the upper surface of the upper shell 1, and both sides of the lower surface of the limit plates 7 are provided. They are all connected to the limit rod 9 through a connecting rod, a fixed block 10 is provided on one side of the upper surface of the lower shell 2, and a hole 11 is opened through the outer surface of the fixed block 10, and an opening that is compatible with the hole 11 is opened on the side of the upper shell 1 close to the fixed block 10. The upper shell 1 and the lower shell 2 are both made of PVC, and the hole 11 and the inner wall of the opening are provided with threads. When the structure is not in use, the spring 4 is in a contracted state, and the limit plate 7 is located inside the slot 3. When the upper shell 1 and the lower shell 2 are fitted together, the corresponding two slots 3 form a complete cylinder.

[0026] During operation, the upper shell 1 and the lower shell 2 are opened, and the slot 3 is clamped on the wire. At the same time, the limit rod 9 will press against the surface of the wire, and the upper shell 1 and the lower shell 2 are closed. During the closing process, the height of the limit rod 9, the limit plate 7, and the connecting plate 5 will rise, causing the spring 4 to stretch. At the same time, the limit rod 9 will be close to the surface of the wire. After closing, the hole 11 will be aligned with the opening position, and bolts are screwed into the hole 11 and the opening to fix it. At this time, the limit rod 9 and the slot 3 clamp the wire to limit it.

[0027] See also Figure 1-5 The utility model provides a technical solution: the outer side of the upper surface of the upper shell 1 is connected to a frame 12 , and the spring 4 , the connecting plate 5 , and the fixing plate 6 are located inside the frame 12 .

[0028] During operation, the frame 12 can block part of the sunlight, reducing the direct sunlight on the spring 4, which is beneficial to the service life of the spring 4.

[0029] See also Figure 1-5 The utility model provides a technical solution: a guide rod 13 is connected to the upper surface of the upper shell 1, and the upper end of the guide rod 13 passes through the connecting plate 5 and is slidably connected to the connecting plate 5.

[0030] During operation, the guide rod 13 can limit the connection plate 5 and prevent the connection plate 5 from being offset when the height is increased.

[0031] See also Figure 1-5 The utility model provides a technical solution: a sealing plate 14 is connected to the outside of the connecting plate 5, the outside of the sealing plate 14 is in contact with the frame 12, and the sealing plate 14 is made of rubber.

[0032] During operation, the sealing plate 14 can prevent external impurities from entering the frame 12 .

[0033] See also Figure 1-5 The utility model provides a technical solution: the outer surface of the limiting rod 9 is covered with rubber.

[0034] During operation, the friction between the limiting rod 9 and the wire can be increased by setting the rubber, thereby ensuring the clamping effect of the limiting rod 9 and the clamping slot 3 on the wire.

[0035] See also Figure 1-5 The utility model provides a technical solution: a limit block 15 is provided on one side of the upper surface of the lower shell 2, and a groove adapted to the limit block 15 is opened on one side of the lower surface of the upper shell 1.

[0036] During operation, through the setting of the limit block 15 and the groove, after the upper shell 1 and the lower shell 2 are fitted together, the limit block 15 will be stuck in the groove, thereby preventing the upper shell 1 and the lower shell 2 from offsetting, making it easier to screw the bolts into the hole 11 and the opening.

[0037] See also Figure 1-5 The utility model provides a technical solution: the surfaces of the upper shell 1 and the lower shell 2 are coated with acrylic paint.

[0038] During operation, the acrylic paint has strong light resistance and weather resistance, which can reduce the damage caused by the outdoor environment to the upper shell 1 and the lower shell 2.

[0039] In summary, open the upper shell 1 and the lower shell 2, clamp the slot 3 on the wire, and at the same time, the limit rod 9 will press against the surface of the wire, and close the upper shell 1 and the lower shell 2. During the closing process, the height of the limit rod 9, the limit plate 7, and the connecting plate 5 will rise, causing the spring 4 to stretch. At the same time, the limit rod 9 will be close to the surface of the wire. After closing, the hole 11 will be aligned with the opening position, and bolts are screwed into the hole 11 and the opening to fix it. At this time, the limit rod 9 and the slot 3 clamp and limit the wire, and the frame 12 and the sealing plate 14 can protect the spring 4, the connecting plate 5 and other structures.
