Description

Technical Field

[0001] The utility model relates to the 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. Its main components are the primary coil, secondary coil and iron core. Transformers are basic equipment for power transmission and distribution and are widely used in industries, agriculture, transportation, urban communities and other fields. Transformers are connected to external electrical equipment through lead wires.

[0003] In order to connect the lead wires to external electrical equipment, the lead wires need to be fixed before they can be connected to the external electrical equipment. At present, due to the different thicknesses of the lead wires of transformers with different specifications, the lead wires of transformers with different specifications need to use corresponding fixing devices, and the upper and lower clamping plates are often locked by two sets of bolts to clamp and limit the lead wires. The process is cumbersome, and the number of lead wires of different transformers is also different, and the corresponding number of devices are also needed to fix them, which limits the applicability. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a transformer lead-out wire structure.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a transformer lead-out wire structure, including a transformer main body, the outer wall of the transformer main body is fixedly connected with a guide rail, a slider is installed inside the guide rail, the top of the slider is fixedly connected with a support plate, the top of the support plate is provided with a mounting groove, and the number of mounting grooves is two, the insides of the two mounting grooves are both provided with mounting bars, the tops of the two mounting bars are both fixedly connected with a U-shaped frame, the outer wall of the U-shaped frame is provided with a lifting groove, and the number of lifting grooves is two, the bottoms of the inner walls of the two lifting grooves are movably connected with clamping screws, the outer walls of both ends of the clamping screws are threadedly connected with lifting blocks, the opposite surfaces of the two adjacent lifting blocks are fixedly connected with clamping plates, and the tops of the two clamping screws are fixedly connected with clamping knobs.

[0006] As a further description of the above technical solution:

[0007] A groove is provided at the bottom of the support plate, and the groove passes through the sliding block. A positioning screw is movably connected to the inner wall of the groove, and the outer walls at both ends of the positioning screw are threadedly connected to positioning plates. A positioning protrusion is fixedly connected to the outer wall of the positioning plate, and a positioning knob is fixedly connected to the other end of the positioning screw.

[0008] As a further description of the above technical solution:

[0009] Both inner walls of the guide rails are provided with positioning grooves, and there are a plurality of positioning grooves, and the other ends of most positioning protrusions are located inside the positioning grooves.

[0010] As a further description of the above technical solution:

[0011] The outer walls on both sides of the support plate are provided with connecting grooves, and the connecting grooves are connected with the installation grooves.

[0012] As a further description of the above technical solution:

[0013] A locking groove is provided inside the mounting strip, and locking springs are fixedly connected to the outer walls on both sides of the support plate, and there are two locking springs respectively, and the other ends of the two locking springs are fixedly connected to a pull plate, and the inner wall of the pull plate is fixedly connected to a locking plate.

[0014] As a further description of the above technical solution:

[0015] One end of the locking plate with an inclined surface is located inside the locking groove, and the locking plate is located between the two locking springs.

[0016] The utility model has the following beneficial effects:

[0017] By installing a slider inside the guide rail, connecting the top of the slider to a support plate, and setting a U-shaped frame on the top of the support plate, when the transformer has multiple lead wires, corresponding sliders, support plates and U-shaped frames can be added inside the guide rail, which can adapt to transformers with different numbers of lead wires. And turning the two clamping knobs respectively drives the two clamping screws connected thereto to rotate, and the lifting blocks threadedly connected to the outer walls of the two ends of the clamping screws respectively drive the clamping plates connected thereto to move relative or opposite to each other, so that lead wires of different sizes are clamped and fixed, thereby improving applicability. In summary, the lead wire structure can flexibly increase the structure for transformers of different specifications, with a simple process, and can meet the clamping of different numbers of lead wires of transformers of different models.

[0018] By setting a positioning screw, turning the positioning knob drives the positioning screw to rotate, and the positioning plates connected to the outer walls of the two ends of the positioning screw and the positioning protrusions connected to the outer walls of the positioning plates move in opposite directions, so that the positioning protrusions enter the corresponding positioning grooves, which is convenient for adjusting and fixing the position of the slider in the guide rail, and ensuring the stability of the lead wire when clamping. When the U-shaped frame is installed on the support plate, the two mounting strips connected to the bottom of the U-shaped frame correspond to the two mounting grooves at the top of the support plate respectively. When the mounting strip enters the mounting groove, the locking plate is pushed outward. At this time, the locking spring is in a stretched state. After the locking plate completely enters the locking groove, the locking spring rebounds to allow the locking plate to enter the locking groove, fixing the mounting strip and the U-shaped frame connected to the top. At the same time, a pull plate is set. By the same principle, the U-shaped frame can be removed for easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
