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. Its core components include a primary coil, a secondary coil and an iron core (magnetic core). When the primary coil is energized, an alternating magnetic field is generated in the iron core, which in turn generates an induced electromotive force in the secondary coil, thereby achieving a change in voltage. It should be noted that the transformer will produce certain losses during operation. Therefore, choosing an energy-efficient transformer is of great significance to improving energy utilization efficiency and promoting green and low-carbon development. In recent years, my country has also been continuously advancing the improvement of transformer energy efficiency. By formulating relevant plans and standards, it has promoted the improvement of transformer energy efficiency and the research and development and application of efficient energy-saving technologies.

[0003] Among them, the transformer lead wire structure is an indispensable part of the transformer. For example, the transformer lead wire can transfer the electric energy generated by the internal winding of the transformer to the external circuit, realizing the power transmission between the power supply and the load; through different connection methods and circuit combinations, the transformer lead wire can realize the adjustment and transformation of different voltages to meet the power supply requirements of different electrical equipment; the transformer lead wire plays an important transmission role in the circuit and can effectively improve the stability of the circuit.

[0004] Currently, when using the transformer lead wire structure, it is first necessary to check the condition of the transformer lead wire to ensure that it is intact, and then use special tools and techniques to connect the lead wire to the appropriate terminal of the transformer so that the transformer can operate. At the same time, it is also necessary to use a clamping structure to fix the position of the lead wire, which can increase the stability of the connection.

[0005] When using a clamping structure to fix the position of the lead, since the size of the existing clamping structure is fixed, but the lead size of the transformer is not necessarily the same, it is easy to need to replace a different clamping structure to fix the position of the lead, which makes the operation more troublesome and easily reduces work efficiency. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide a transformer lead wire structure to solve the technical problem that since the size of the existing clamping structure is fixed, but the lead wire size of the transformer is not necessarily the same, it is easy to need to replace different clamping structures to fix the position of the lead wire, which is troublesome to operate and easily reduces work efficiency.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transformer lead wire structure, comprising a box body, a lower clamping block is movably connected to the top of the box body, and an upper clamping block is movably connected to the top of the lower clamping block, a first groove is provided on the adjacent side of the lower clamping block and the upper clamping block, and an air bag is provided in the first groove, a group of lead rings is provided on the adjacent side of the air bag, a group of second grooves is provided on the adjacent side of the lower clamping block and the upper clamping block, one end of a spring is fixedly connected in the second groove, and the other end of the spring is fixedly connected to a pressing plate.

The pressing plate can then squeeze the airbag to cause the gas in the airbag to move, thereby causing the airbag to expand, until a group of lead rings on the adjacent side of the airbag can be used to fix multiple lead positions. When the airbag cannot continue to expand after the lead position is fixed, the airbag can react to the pressing plate, and the spring between the pressing plate and the second groove is squeezed to cause the pressing plate to move upward until the airbag and the pressing plate reach a balanced state. This is beneficial for the airbag to expand to different degrees according to the actual size of the lead, so that leads of different sizes can be fixed.

[0010] By adopting the above technical solution, liquid, such as water or night coolant, is transported into the cavity through the liquid injection hole, so that the lower clamp block and the upper clamp block can play a cooling role. At the same time, when the external temperature is high, it can play a heat insulation role, which facilitates better use of the device.

[0011] The utility model is further configured that a plurality of matching first threaded holes are provided between the box body and the lower clamping block, and first bolts are threadedly connected in the first threaded holes.

[0012] By adopting the above technical solution, the first bolt can be used to install the box body and the lower clamp block, which can ensure the tight connection between the box body and the lower clamp block and facilitate improving the working effect of installing and disassembling the lower clamp block.

[0014] By adopting the above technical solution, the lower clamp block and the upper clamp block can be positioned by the card slot and the card block, so that the pressing plate can stably squeeze the airbag in the first groove. At the same time, the lower clamp block and the upper clamp block are connected by the second bolt, which can ensure the tightness of the connection and facilitate improving the work efficiency of installation and disassembly between the lower clamp block and the upper clamp block.

[0015] The utility model is further configured such that sealing rings are provided in the first threaded hole and the second threaded hole.

[0016] By adopting the above technical solution, the sealing effect between the first bolt, the second bolt and the first threaded hole, the second threaded hole can be enhanced. At the same time, the contact between the first bolt and the second bolt and the first threaded hole and the second threaded hole can be reduced through the sealing ring, thereby reducing wear and extending its service life.

[0017] The utility model is further configured such that the pressing plate and the first groove are matched in size and position, and the pressing plate moves in the first groove.

[0018] By adopting the above technical solution, the stability of the pressing plate on the airbag can be increased, which facilitates increasing the accuracy of the operation.

[0020] By adopting the above technical solution, the tiny gap between the card slot and the card block can be filled, thereby improving the sealing between them and preventing liquid or dust from entering the upper clamp block and the lower clamp block through the gap to affect use.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] The utility model can place the lead wire in the lead wire ring on the top of the lower clamp block first, and then connect the lower clamp block and the upper clamp block so that the pressing plate is located in the first groove. The pressing plate can squeeze the airbag to make the gas in the airbag move, thereby causing the airbag to expand, until a plurality of lead wire positions can be fixed by a group of lead wire rings on the adjacent side of the airbag. When the airbag cannot continue to expand after the lead wire position is fixed, the airbag can react to the pressing plate, and the spring between the pressing plate and the second groove is squeezed to make the pressing plate move upward until the airbag and the pressing plate reach a balanced state. This is beneficial for making the airbag expand to different degrees according to the actual size of the lead wire, so that leads of different sizes can be fixed. The operation is simple and it is convenient to improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
