Description

Technical Field

[0001] This utility model relates to the field of frequency converter technology, specifically to a connector for frequency converters. Background Technology

[0002] A frequency converter is a power control device that uses frequency conversion technology and microelectronics to control an AC motor by changing the frequency of the power supply. Due to its simple parameter settings and good energy-saving effect, it can be widely used in equipment manufacturing, energy conservation in fields such as fans and pumps.

[0003] The existing frequency converters use threaded connections for electrical connectors, which makes disassembly inconvenient and prevents quick installation and removal. Furthermore, the bolts may fall out accidentally when being removed, requiring the search for suitable screws for installation, which is time-consuming and labor-intensive. Therefore, further improvements are needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a connector for a frequency converter, comprising a connection port and a connector head. A fixing rod is fixedly installed on one side of the front of the connection port, and a mounting bracket is fixedly installed at the end of the fixing rod. Limiting holes for limiting the position are provided on both sides of the mounting bracket. A mounting shell is sleeved on the outer side of the connector head, and the mounting shell is inserted into the interior of the mounting bracket. The upper and lower sides of the mounting shell are provided with auxiliary installation limiting and convenient disassembly components.

[0005] As an optimization, the convenient assembly and disassembly component includes a plug rod and a limiting rod that are slidably inserted into the mounting shell, with the limiting rod corresponding to the insertion of the limiting hole. A spring is fixedly installed between the two plug rods, and a pressing block is fixedly installed at the opposite end of the two limiting rods. A linkage component is provided in the middle of the mounting shell to drive the limiting rod to move inward out of the limiting hole.

[0006] As an optimization, the linkage includes an extrusion head slidably connected in the middle of the mounting shell, a connecting rod fixedly installed on the side of the extrusion head near the insertion rod, a connecting rod rotatably connected to the end of the connecting rod and the insertion rod located in the mounting shell, and a second spring fixedly installed between the extrusion head and the inner wall of the mounting shell.

[0007] As an optimization, the side of the extrusion block closest to the extrusion head is inclined, and both sides of the extrusion head closest to the two sets of extrusion blocks are inclined.

[0008] As an optimization, a limiting block is fixedly installed on the outer side of the limiting rod, and a tension spring is fixedly installed on one side of the limiting block, and the tension spring force is less than the spring force of the second spring.

[0009] As an optimization, a pressure plate is fixedly installed at one end of the insertion rod outside the mounting housing, and the pressure plate is in a bent arc shape.

[0010] As an optimization, a limiting plate is fixedly installed on the middle of both sides of the mounting shell, and a limiting groove is opened in the middle of the inner wall of both sides of the limiting hole. The limiting plate is slidably inserted into the limiting groove. By aligning the limiting plate with the limiting groove and inserting it, it can play a guiding and limiting role.

[0011] The beneficial effects of this utility model are:

[0012] This connector for frequency converters works by pressing the pressure plates on both sides, which causes the plug rods on both sides to move closer together. The connecting rod then pushes the connecting rod, which in turn pushes the compression head to slide and compress the second spring, thus stopping the compression block. At this time, the limit rods on both sides will move closer together into the mounting housing under the action of the tension spring, making it convenient and quick to install and remove.

Detailed Implementation

[0019] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] 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.

[0021] Please see Figure 1-2 A connector for a frequency converter includes a connection port 1 and a connector head 2. A fixing rod 3 is fixedly installed on one side of the front of the connection port 1. A mounting bracket 4 is fixedly installed at the end of the fixing rod 3. Limiting holes 5 for limiting are opened on both sides of the mounting bracket 4. A mounting shell 6 is sleeved on the outside of the connector head 2 and is inserted into the inside of the mounting bracket 4. Limiting plates 17 are fixedly installed in the middle of both sides of the mounting shell 6. Limiting grooves 18 are opened in the middle of the inner walls on both sides of the limiting holes 5, and the limiting plates 17 are slidably inserted into the limiting grooves 18. By aligning the limiting plates 17 with the limiting grooves 18 and inserting them, the limiting plate can play a guiding and limiting role. The upper and lower sides of the mounting shell 6 are provided with auxiliary installation limiting and easy disassembly and assembly components 7 for disassembly.

[0022] Please see Figure 3-4 The easy-to-install and disassemble component 7 includes a plug rod 8 and a limiting rod 9 that are slidably inserted into the mounting shell 6. A pressure plate 16 is fixedly installed at one end of the plug rod 8 outside the mounting shell 6, and the pressure plate 16 is bent into an arc shape. The limiting rod 9 is inserted into the limiting hole 5. A spring 10 is fixedly installed between the two plug rods 8. A pressing block 11 is fixedly installed at the opposite end of the two limiting rods 9. A linkage component is provided in the middle of the mounting shell 6 to drive the limiting rod 9 to move inward out of the limiting hole 5. By pressing the plug rods 8 on both sides closer together, the limiting rod 9 will be driven to move into the mounting shell 6 through the linkage component. At this time, the mounting shell 6 can be inserted into the mounting bracket 4. After the plug rod 8 is released, the limiting rod 9 will be reset and inserted into the limiting hole 5 under the action of the linkage component, thus achieving the function of limiting installation.

[0023] Please see Figure 3-4The linkage includes an extrusion head 12 slidably connected in the middle of the mounting shell 6. The side of the extrusion block 11 near the extrusion head 12 is inclined, and both sides of the extrusion head 12 near the two sets of extrusion blocks 11 are inclined. A connecting rod 13 is fixedly installed on the side of the extrusion head 12 near the insertion rod 8. The connecting rod 13 and the insertion rod 8 are rotatably connected to a connecting rod 14 at one end inside the mounting shell 6. A second spring 15 is fixedly installed between the extrusion head 12 and the inner wall of the mounting shell 6. The spring 15 will drive the extrusion head 12 to press against the two extrusion blocks 11, so that the initial position of the limiting rod 9 protrudes out of the outer side of the mounting shell 6. By pressing the two insertion rods 8 closer to each other, the connecting rod 14 can push the connecting rod 13, so that the extrusion head 12 will no longer press the extrusion block 11. At this time, the two limiting rods 9 will move closer to each other into the mounting shell 6, which facilitates installation and disassembly.

[0024] Please see Figure 3-4 A limiting block is fixedly installed on the outer side of the limiting rod 9, and a tension spring is fixedly installed on one side of the limiting block. The tension spring has a smaller elastic force than the spring 15. The spring 15 itself will drive the extrusion head 12 to extrude the extrusion block 11, which will cause the initial position of the limiting rod 9 to be outside the mounting shell 6. When the tension spring is no longer under force, the limiting rod 9 will move into the mounting shell 6.

[0025] During installation, first, the mounting shell 6 is placed on the outside of the connector 2. Then, the pressure plates 16 on both sides are pressed, which will cause the insertion rods 8 on both sides to move closer to each other. Then, the connecting rod 14 will drive the connecting rod 13 to move towards the pressing head 12. This will cause the pressing head 12 to press the second spring 15, no longer limiting the pressing block 11. Therefore, the limiting rods 9 on both sides will be pulled into the mounting shell 6 under the action of the tension spring. At this time, the connector 2 can be inserted into the connecting port 1, and the mounting shell 6 will be inserted into the mounting bracket 4. As the pressure plate 16 is released, the pressing head 12 will press the pressing blocks 11 on both sides under the elastic force of the second spring 15. This will cause the limiting rods 9 to move out and insert into the limiting hole 5, thus achieving the function of limiting the installation.

[0026] Similarly, during disassembly, pressing the pressure plates 16 on both sides will cause the limiting rod 9 to move back into the mounting shell 6, thus making it easy to pull the mounting shell 6 outward for disassembly.

[0027] In summary, this connector for frequency converters, by pressing the pressure plates 16 on both sides, will cause the plug rods 8 on both sides to move closer to each other. The connecting rod 14 can then squeeze and push the connecting rod 13, which will push the squeezing head 12 to slide and compress the spring 15, thus stopping the squeezing block 11 from being squeezed. At this time, the limiting rods 9 on both sides will move closer to each other and into the mounting housing 6 under the action of the tension spring, thus facilitating quick and easy installation and disassembly.
