Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer installation 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, the secondary coil and the iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. It is divided into large transformers and small transformers. Small transformers mainly refer to single-phase transformers below 20kV·A and three-phase transformers below 50kV·A. Their load rate and utilization rate are generally low. The inductive loads they carry are generally not capacitively compensated. Small transformers are a common equipment in factory electrical control systems. With the large-scale application of electronic components in power plant control, monitoring and automatic circuits, the application of small transformers is becoming more and more extensive.

[0003] For example, in the prior art, a utility model with application number 202320042983.X discloses a small transformer. Traditional small transformers generally include structures such as a shell, an iron core, a terminal seat, and pins. When installed and used, the pins are directly welded to the circuit board. Although it is simple and convenient, in actual use, the small transformer as a whole is only fixed by the welding support of the pins, which is easily affected by external forces and the pin welding points may break, affecting the normal use of the transformer. In view of this, the present application proposes a transformer installation structure. Utility Model Content

[0009] Preferably, the fixing sleeve is symmetrically divided into two sections, and connecting ear blocks are provided at the ends of the two sections of the fixing sleeve, and a connecting screw is threadedly inserted between the two connecting ear blocks that are aligned with each other.

[0010] Preferably, the transformer body comprises a transformer housing, a transformer winding assembled in the transformer housing, and pins located at the bottom of the transformer housing, and the fixing frame is sleeved on the transformer housing.

The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0024] Example

[0025] See also Figures 1 to 5 , the utility model preferably provides a technical solution:

[0026] A transformer mounting structure is applied to a transformer body 1, comprising a fixed sleeve frame 2 and a support sheet 4, wherein the fixed sleeve frame 2 is sleeved on the transformer body 1. Specifically, the transformer body 1 comprises a transformer housing 7, a transformer winding 8 assembled in the transformer housing 7, and pins 9 located at the bottom of the transformer housing 7, and the fixed sleeve frame 2 is sleeved on the transformer housing 7. A collar 3 is provided on the outer wall of the fixed sleeve 2, and at least one pair of collars 3 is provided; the support sheet 4 is vertically penetrated on the collar 3 and can move up and down, and a positioning piece 5 for limiting the upward and downward movement of the support sheet 4 is provided on the collar 3, and a foot piece 14 is provided at the bottom end of the support sheet 4. Through this structural method, after the pins 9 of the transformer body 1 are welded on the circuit board, the support sheet 4 is pulled down to make the foot piece 14 abut against the circuit board, and a mounting hole 15 is opened on the foot piece 14. The mounting hole 15 is used to cooperate with the screw to fix the support sheet 4 on the circuit board, and then the positioning piece 5 is used to limit the upward and downward movement of the support sheet 4. Thus, the fixed sleeve 2 and the support sheet 4 constitute a supporting frame to reinforce and support the transformer body 1, effectively solving the problem that the stability is insufficient when only the pins 9 are welded and fixed, and the pins 9 are easily broken at the welding position due to the influence of external force, thereby improving the installation strength of the transformer body 1 and ensuring that the transformer body 1 can work stably.

[0027] As a preferred implementation manner of this embodiment, the positioning member 5 includes a through hole 16 opened on the ring 3 and a stopper 18 embedded in the through hole 16. The stopper 18 can be embedded in the ring 3 to press against the support sheet 4. A rubber pad 20 is provided on the side of the stopper 18 facing the ring 3. Specifically, a stud 17 is passed through the through hole 16, and the stud 17 is fixed on the fixed sleeve 2. An adjustment groove 13 for the stud 17 to pass through is vertically opened on the support sheet 4. The stopper 18 is sleeved on the stud 17. A screw sleeve 19 that is threadedly sleeved with the stud 17 is provided on the side of the stopper 18 away from the ring 3. The screw sleeve 19 is screwed, and the threaded cooperation between the screw sleeve 19 and the stud 17 is utilized to push the stopper 18 to be embedded in the through hole 16 to press against the support sheet 4, thereby relatively positioning the support sheet 4 and the fixed sleeve 2. The rubber pad 20 on the stopper 18 can increase the friction between the stopper 18 and the support sheet 4, which is beneficial to the effective positioning of the support sheet 4.

[0028] In this embodiment, the top end of the adjustment groove 13 passes through the top wall of the support sheet 4, which is conducive to inserting the support sheet 4 into the ring 3 or pulling out the support sheet 4; the fixed sleeve 2 is symmetrically divided into two sections, and the ends of the two sections of the fixed sleeve 2 are provided with connecting ear blocks 12, and a connecting screw 21 is threadedly penetrated between the two aligned connecting ear blocks 12. By setting the fixed sleeve 2 into two sections, the two sections of the fixed sleeve 2 are connected and fixed by using the connecting ear blocks 12 and the connecting screws 21, which can facilitate the fixed sleeve 2 to be sleeved and assembled on the transformer body 1, and is easy to produce and assemble.

[0029] In this embodiment, a pair of limiting ridges 6 are provided on the opposite side walls of the transformer housing 7, the fixed sleeve 2 is located between the pair of limiting ridges 6, a positioning hole 10 is opened on the side wall of the transformer housing 7 adjacent to the limiting ridge 6, and a positioning column 11 that is plugged into and adapted to the positioning hole 10 is provided on the inner wall of the fixed sleeve 2. Through the plugging of the positioning hole 10 and the positioning column 11, and the positioning of the fixed sleeve 2 by the limiting ridge 6, the fixed sleeve 2 can be stably mounted on the transformer body 1, the structure of the transformer body 1 is reinforced, and the structural strength of the transformer body 1 is improved.

[0030] The transformer installation structure is as follows: after the pins 9 of the transformer body 1 are welded on the circuit board, the support sheet 4 is pulled down to make the pin 14 abut against the circuit board, and then the support sheet 4 is fixed to the circuit board by using the mounting hole 15 in combination with the screw, and then the screw sleeve 19 is screwed, and the threaded cooperation between the screw sleeve 19 and the stud 17 is used to push the block 18 to be embedded in the through hole 16 to tighten the support sheet 4. The rubber pad 20 on the block 18 can increase the friction between the block 18 and the support sheet 4, thereby relatively positioning the support sheet 4 and the fixed frame 2. As a result, the fixed frame 2 and the support sheet 4 constitute a support frame to reinforce and support the transformer body 1. The invention effectively solves the problem that the stability of only using the pin 9 for welding is insufficient, and the pin 9 is easily broken at the welding position due to the influence of external force, thereby improving the installation strength of the transformer body 1 and ensuring that the transformer body 1 can work stably. On this basis, with the positioning column 11 plugged into the positioning hole 10, and the upper and lower limit of the fixed sleeve frame 2 by the limiting convex strip 6, the fixed sleeve frame 2 can be stably mounted on the transformer body 1, and the structure of the transformer body 1 can be reinforced, the structural strength of the transformer body 1 is improved, the transformer body 1 is more durable, and the practical life of the transformer body 1 is extended.
