[0002] A modular transformer is a power device that integrates the transformer body, high and low voltage power distribution equipment, control system, and other functional units into independent modules, which are then combined through standardized interfaces. Its core features are modular design, flexible assembly, and rapid deployment, making it suitable for scenarios with high requirements for installation efficiency and scalability.

[0003] A modular combined transformer is disclosed in the related technology (publication number: CN207993651U). The disclosed technical solution is that the display screen can intuitively display status data, can automatically illuminate when the transformer is being repaired, has heat dissipation function and can dry the tank, and prevents small animals from entering and affecting the operation of the device.

[0004] The above-disclosed technical solutions reveal the following problems: the transformer leads its internal circuitry to the outside through bushings and then connects it to the circuitry of external equipment. To improve the efficiency of the wiring process, we propose a modular combined transformer that facilitates quick wiring.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the transformer wiring problem in the prior art, this utility model provides a modular combined transformer that facilitates quick wiring. It employs a structure that facilitates connection to the line, combined with a wiring distance adjustment structure, to achieve easy connection with the leads. The specific technical solution is as follows:

[0007] A modular combined transformer for easy and quick wiring includes a lead extending from the top of the transformer. A junction box is slidably mounted on the top of the transformer. A limiting block is embedded in the inner cavity of the junction box, forming a locking cavity between the limiting block and the inner wall of the junction box. An elastic conductor is locked in the locking cavity. A wiring hole extending into the inner cavity is opened on the top of the junction box. A locking push rod extending to one end of the elastic conductor is embedded in the top of the junction box. The other end of the elastic conductor is connected to the lead through a spring-type extension wire.

[0008] In the above technical solution, a winding post is fixedly connected to the top of the junction box, and the extension wire is spirally wound around the outer wall of the winding post. One end of the extension wire is connected to the lead wire, and the other end of the extension wire extends into the inner cavity of the junction box and is connected to the elastic conductor.

[0009] A wire-blocking disc is fixed to one end of the winding post near the junction box. The wire-blocking disc has a wire-releasing hole, and the extension wire passes through the inside of the wire-releasing hole.

[0010] The bottom of the junction box is provided with a dovetail groove, and the top of the transformer is fixedly connected to a dovetail slider that is slidably disposed inside the dovetail groove. The top of the transformer is provided with a wiring distance adjustment component for adjusting the position of the junction box.

[0011] The wiring distance adjustment assembly includes a lead screw rotatably mounted on the top of the transformer, and the outer wall of the lead screw is threadedly connected to a displacement seat fixed on the junction box.

[0012] A guide rod parallel to the lead screw is fixed to the top of the transformer, and the displacement seat is sleeved on the outside of the guide rod.

[0013] The outer wall of the snap-fit ​​push rod is fitted with a support fixed to the top of the junction box. An operating component is fixed to the end of the snap-fit ​​push rod located outside the junction box, and an elastic component is provided between the operating component and the support, which is sleeved on the outside of the snap-fit ​​push rod.

[0014] The elastic conductor is a U-shaped spring sheet.

[0015] Compared with the prior art, the beneficial effects of this utility model are: this modular combined transformer facilitates quick wiring.

[0016] 1. When connecting to the transformer, extend the external wiring from the wiring hole to the inner wall of the junction box and between it and the elastic conductor. Then, release the locking push rod, allowing the elastic conductor to lock the external wiring between itself and the inner wall of the junction box. This allows the external wiring to connect to the extension wire through the elastic conductor, and then to the lead wire through the extension wire. This makes the process of connecting the external wiring to the transformer lead wire more convenient. When it is necessary to disconnect the external wiring from the lead wire, push the locking push rod and then remove the external wiring from the wiring hole, thus facilitating the maintenance process for relevant personnel.

[0017] 2. The extension wires are wound around the outer wall of the winding post in sequence. After the extension wires are wound around the winding post, they are kept connected to the lead wire as the junction box moves, ensuring that the length of the wiring is extended as the junction box is extended, thus avoiding the disconnection between the external wiring and the lead wire.

[0018] Third, the position of the junction box can be adjusted by the wiring distance adjustment component, so that the junction box can be adjusted according to the external wiring position during operation, thereby bringing convenience to the wiring process. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The following are specific implementation cases and appendices. Figure 1-4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0026] A modular combined transformer for easy and quick wiring includes a lead wire 2 extending from the top of the transformer 1. The lead wire 2 is fixed by a bushing fixed to the top of the transformer 1, and external equipment is connected to the transformer 1 through the lead wire 2. A junction box 4 is slidably mounted on the top of the transformer 1. A limiting block 8 is embedded in the inner cavity of the junction box 4, and a retaining cavity 9 is formed between the limiting block 8 and the inner wall of the junction box 4. An elastic conductor 7 is engaged in the retaining cavity 9. The limiting block 8 is composed of a combination of square and circular bodies. The limiting block 8 is fixedly embedded in the inner cavity of the junction box 4. The sheet-like elastic conductor 7 is bent into a U-shape to generate elasticity, and then inserted into the retaining cavity formed by the limiting block 8 and the inner wall of the junction box 4 through the U-shaped slot.

[0027] The top of the junction box 4 has a wiring hole 6 extending into the inner cavity. A wiring hole 6 penetrating the top of the junction box 4 is also provided above one side of the elastic conductor 7. The wiring hole 6 is angled at the top of the junction box 4. A locking push rod 5 slides angledly into the top of the junction box 4 from the other side and extends into the inner cavity of the junction box 4. The end of the locking push rod 5 is fitted against the surface of the elastic conductor 7. A locking push rod 5 extending to one end of the elastic conductor 7 is embedded in the top of the junction box 4. The other end of the elastic conductor 7 is connected to the lead wire 2 via a spring-type extension wire 3.

[0028] When connecting to transformer 1, first slide the snap-fit ​​push rod 5 into the through hole at the top of the junction box 4, so that the snap-fit ​​push rod 5 is pushed to one side of the elastic conductor 7, so that the elastic conductor 7 and the inner wall of the junction box 4 are separated. Then, extend the external wiring from the wiring hole 6 to the space between the inner wall of the junction box 4 and the elastic conductor 7. Then release the snap-fit ​​push rod 5, so that the elastic conductor 7 snaps the external wiring between the elastic conductor 7 and the inner wall of the junction box 4, so that the external wiring is connected to the extension wire 3 through the elastic conductor 7, and connected to the lead wire 2 through the extension wire 3, making the operation of connecting the external wiring to the transformer lead wire 2 more convenient.

[0029] When it is necessary to disconnect the external wiring from lead 2, push the snap-fit ​​push rod 5, and then remove the external wiring from the wiring hole 6, thereby facilitating the maintenance process for relevant personnel.

[0030] The junction box 4 has a winding post 13 fixedly attached to its top. An extension wire 3 is spirally wound around the outer wall of the winding post 13. One end of the extension wire 3 is connected to the lead wire 2, and the other end extends into the inner cavity of the junction box 4 and connects to the elastic conductor 7. The winding post 13 is horizontally located between the lead wire 2 and the junction box. The column 19 is vertically fixed to the top of the transformer 1, and the top of the column 19 is vertically fixed to the bottom of the outer wall of the winding post 13.

[0031] The extension wire 3 is wound around the outer wall of the winding post 13 in sequence. After the extension wire 3 is wound around the winding post 13, it is kept connected to the lead wire 2 through the extension wire 3 as the junction box 4 moves, ensuring that the length of the wiring is extended as the junction box 4 is extended, and avoiding the disconnection between the external wiring and the lead wire 2.

[0032] It is worth noting that a wire-blocking plate 10 is fixedly connected to one end of the winding post 13 near the junction box 4. The wire-blocking plate 10 has a wire-releasing hole 11, and the extension wire 3 passes through the interior of the wire-releasing hole 11. The extension wire 3 is limited at its end by the wire-blocking plate 10, so that after the extension wire passes through the wire-releasing hole 11, it is stretched open with the junction box 4, ensuring the stability of the extension wire 3 during the stretching process.

[0033] In addition, the bottom of the junction box 4 is provided with a dovetail groove 24, and the top of the transformer 1 is fixedly connected to a dovetail slider 23 that is slidably disposed inside the dovetail groove 24. The top of the transformer 1 is also provided with a wiring distance adjustment component for adjusting the position of the junction box 4. Two T-shaped dovetail grooves 24 are symmetrically provided on the bottom of the junction box 4, and two support columns are symmetrically fixedly installed on the top of the transformer 1. Dovetail sliders 23, also T-shaped, are fixedly installed on the top of the support columns. This allows the junction box 4 to slide against the outer wall of the dovetail slider 23, ensuring the stability of the junction box 4 during movement. The wiring distance adjustment component allows the junction box 4 to be adjusted according to the external wiring position during operation, thus facilitating the wiring process.

[0034] Additionally, the wiring distance adjustment assembly includes a lead screw 14 rotatably mounted on top of the transformer 1, with a displacement seat 25 fixed to the junction box 4 connected to the outer wall of the lead screw 14 by threads. Two parallel fixing plates 22 are vertically fixedly mounted on top of the transformer 1, located below and on either side of the junction box 4. Bearings are fixed to the opposite surfaces of the two fixing plates 22 via bearing seats. Both ends of the lead screw 14 are embedded within the two bearings, and an operating rod is fixedly connected to one end of the lead screw 14.

[0035] Rotating the operating lever causes the lead screw 14 to rotate, which in turn causes the displacement seat 25, which is threadedly connected to the lead screw 14, to move the junction box 4, thereby adjusting the junction box 4 to the position where it is connected to the external wiring.

[0036] Furthermore, a guide rod 15 parallel to the lead screw 14 is fixedly connected to the top of the transformer 1, and a displacement seat 25 is sleeved on the outside of the guide rod 15. The two ends of the guide rod 15 are respectively vertically fixed to the opposite surfaces of the two fixing plates 22, and the displacement seat 25 slides against the outer wall of the guide rod 15.

[0037] During the process of adjusting the position of the junction box 4 by rotating the lead screw 14 through the displacement seat 25, the displacement seat 25 slides against the outer wall of the guide rod 15. The guide rod 15, which is parallel to the lead screw 14, ensures the stability of the movement of the displacement seat 25, thereby ensuring the stability of the position adjustment process of the junction box 4.

[0038] The outer wall of the snap-fit ​​push rod 5 is fitted with a support 17 fixed to the top of the junction box 4. An operating element 21 is fixed to the end of the snap-fit ​​push rod 5 located outside the junction box 4. An elastic element 16, sleeved on the outside of the snap-fit ​​push rod 5, is provided between the operating element 21 and the support 17. The elastic force of the elastic element 16 is less than that of the elastic conductor 7. The snap-fit ​​push rod 5 slides within the through hole at the top of the junction box 4. The elastic element 16 can be a compression spring, with its two ends fixed to the opposite surfaces of the support 17 and the operating element 21, respectively. The elastic element 16 slides and extends against the outer wall of the snap-fit ​​push rod 5.

[0039] Since the elastic force of the elastic element 16 is less than that of the elastic conductor 7, after the snap-fit ​​push rod 5 opens the elastic conductor 7 to snap-fit ​​and fix the external wiring, the elastic force of the elastic element 16 drives the snap-fit ​​push rod 5 to move away from the surface of the elastic conductor 7 through the operating element 21, and at the same time the elastic conductor 7 resets and fixes the external wiring inside the wiring hole 6.

[0040] The elastic conductor 7 is a U-shaped spring. The U-shaped spring has the characteristic of elastic deformation. The U-shaped spring is made of conductive material to ensure the conductivity between the lead 2 and the external wire.
