Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a voltage regulating device for a rectifier transformer. Background Technology

[0002] A rectifier transformer is a special transformer designed to power rectifier circuits. Its core function is to convert the AC voltage in the circuit into an AC voltage suitable for the rectifier circuit. At the same time, it works with rectifier components (such as diodes and thyristors) to convert AC to DC. In the application of rectifier transformers, the output voltage needs to be adjusted according to the actual operating conditions. When adjusting the voltage, a rectifier transformer voltage regulating device is generally used.

[0003] However, the existing equipment has the following shortcomings: When connecting wires, the existing equipment generally uses bolts and knobs to make the wires and connectors come into close contact. However, bolts and knobs are cumbersome, making it difficult for users to quickly connect the wires.

[0004] Therefore, we propose a voltage regulating device for rectifier transformers to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, which makes it difficult for users to quickly install and connect wires, resulting in low installation efficiency. Therefore, a rectifier transformer voltage regulating device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rectifier transformer voltage regulating device, comprising a housing, a handle, an regulator, an external connector, a display screen, and a quick-connect device. The handle is fixedly connected to the upper surface of the housing, the regulator is installed at the upper end of the housing, the external connector is fixedly connected to the surface of the housing, the display screen is fixedly connected to the surface of the external connector, and the quick-connect device is installed on the surface of the external connector. The quick-connect device includes a connector head and a fixing block. The connector head is fixedly connected to the surface of the external connector, and the fixing block is fixedly connected to the end of the connector head away from the external connector. A pressure plate is slidably connected to the surface of the connector head. A contact block is fixedly connected to the side of the pressure plate near the external connector. A first limiting ring is fixedly connected to the end of the pressure plate away from the contact block, and a second limiting ring is fixedly connected to the end of the fixing block near the first limiting ring.

[0007] Furthermore, a first spring is sleeved and connected to the surface of the connector.

[0008] Furthermore, one end of the first spring is fixedly connected to the inside of the first limiting ring, and the end of the first spring away from the first limiting ring is fixedly connected to the inside of the second limiting ring. By setting the first spring, a reset force can be applied to the pressure plate, reducing the difficulty of the pressure plate resetting and pressing the wire during use.

[0009] Furthermore, a pull rod is fixedly connected to the surface of the pressure plate, and the pull rod is slidably connected to the inside of the fixing block. The pull rod facilitates the movement of the pressure plate.

[0010] Furthermore, an auxiliary component is fixedly provided on the side of the external connector. The auxiliary component includes a support frame and a mounting plate, and the mounting plate is fixedly connected to the side of the support frame.

[0011] Furthermore, the mounting plate is fixedly connected to the side of the external connector by bolts.

[0012] Furthermore, a first stop block is fixedly connected inside the support frame, and a second stop block is fixedly connected inside the support frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a quick-connect device, the wires can be connected quickly and effectively, which can stabilize the wires and reduce the need for existing equipment to connect wires. Generally, the wires are tightly connected to the connector by screws and knobs, which is cumbersome and makes it difficult for users to quickly connect the wires. This quick-connect device enables the wires to be connected quickly, which is convenient for users to install quickly and improves the user's connection efficiency.

[0015] 2. In this utility model, by setting an auxiliary component, the wire is effectively limited and supported, which plays a role in restricting the position of the wire. This reduces the situation where the wire is easily tangled together during use, and the copper wire at the connection between the wire and the connector is too long, causing a short circuit and damaging the equipment. This auxiliary component realizes the support and limitation of the wire, improving the practicality of the equipment. Attached Figure Description

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a rectifier transformer voltage regulating device, including a housing 1, a handle 2, an regulator 3, an external connector 4, a display screen 5, and a quick-connect device 6. The handle 2 is fixedly connected to the upper surface of the housing 1, the regulator 3 is installed at the upper end of the housing 1, the external connector 4 is fixedly connected to the surface of the housing 1, and the display screen 5 is fixedly connected to the surface of the external connector 4.

[0025] The outer casing 1 is made of high-strength cold-rolled steel plate with anti-corrosion treatment and an internal insulation layer for high safety; the handle 2 is made of insulating plastic with anti-slip texture for easy handling; the regulator 3 is a precision potentiometer with high adjustment accuracy and stable voltage control; the external connector 4 is a copper conductive component with good conductivity and gold-plated surface for oxidation prevention; the display screen 5 is a high-definition LCD screen that can display voltage and current parameters in real time.

[0026] The following section will explain the specific settings and functions of its quick-connect device 6 and auxiliary components 7.

[0027] In this embodiment: the quick-connect device 6 is installed on the surface of the external connector 4. The quick-connect device 6 includes a connector 61 and a fixing block 62. The connector 61 is fixedly connected to the surface of the external connector 4. The fixing block 62 is fixedly connected to the end of the connector 61 away from the external connector 4. A pressure plate 63 is slidably connected to the surface of the connector 61. A contact block 64 is fixedly connected to the side of the pressure plate 63 near the external connector 4. A first limiting ring 66 is fixedly connected to the end of the pressure plate 63 away from the contact block 64. A second limiting ring 67 is fixedly connected to the end of the fixing block 62 near the first limiting ring 66.

[0028] Specifically, a first spring 68 is sleeved on the surface of the connector 61.

[0029] Specifically, one end of the first spring 68 is fixedly connected to the inside of the first limiting ring 66, and the end of the first spring 68 away from the first limiting ring 66 is fixedly connected to the inside of the second limiting ring 67.

[0030] In this embodiment: by setting the first spring 68, a reset force can be applied to the pressure plate 63, reducing the difficulty of the pressure plate 63 resetting and pressing the wire during use.

[0031] Specifically, a pull rod 65 is fixedly connected to the surface of the pressure plate 63. The pull rod 65 is slidably connected to the inside of the fixing block 62. The pull rod 65 is provided to facilitate the movement of the pressure plate 63.

[0032] In this embodiment: an auxiliary component 7 is fixedly provided on the side of the external connector 4. The auxiliary component 7 includes a support frame 71 and a mounting plate 74, and the mounting plate 74 is fixedly connected to the side of the support frame 71.

[0033] Specifically, the mounting plate 74 is fixedly connected to the side of the external connector 4 by bolts 75.

[0034] Specifically, a first stop 72 is fixedly connected inside the support frame 71, and a second stop 73 is fixedly connected inside the support frame 71. The second stop 73 is an insulating plastic block, which cooperates with the first stop 72 to form an electrical cable channel.

[0035] Working principle: When using the device, the user connects the circuit requiring rectification to the connector 61 on the surface of the external connector 4. The current in the circuit is adjusted to a suitable voltage using the rotary adjuster 3 on the upper part of the device. When connecting the wire to the connector 61, the user pulls the lever 65, causing the pressure plate 63 to compress the first spring 68, which moves across the surface of the connector 61. The pressure plate 63 then moves, causing the contact block 64 to detach from the surface of the external connector 4. After the wire to be connected is wound around the connector 61, the user releases the lever 65, and the first spring 68 moves. Spring 68 resets, causing pressure plate 63 and contact block 64 to press the wire onto the surface of connector 4 and secure it to connector 61. By setting quick-connect device 6, the wire can be connected quickly and securely. This reduces the need for conventional equipment to use bolts 75 and knobs to tightly connect the wire to connector 61, which is cumbersome and makes it difficult for users to quickly connect the wire. This quick-connect device 6 enables quick connection of the wire, making it convenient for users to install quickly and improving connection efficiency.

[0036] After the wires are connected, the device integrates the wires with the inside of the support frame 71. The wires slide along the side of the second stop 73 to the upper surface of the first stop 72. Then, the wires slide through the first stop 72 to the lower end of the first stop 72 for limiting and blocking. By setting the auxiliary component 7, the wires are effectively limited and supported, which restricts the position of the wires. This reduces the problems that occur when the wires are easily tangled during use, and the long copper wires at the connection between the wires and the connector 61 can cause short circuits and damage to the equipment. This auxiliary component 7 achieves the support and limitation of the wires, improving the practicality of the device.

[0037] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
