Description

Technical Field

[0001] This utility model relates to the field of inverter wiring hole technology, specifically a waterproof mechanism for inverter wiring holes. Background Technology

[0002] In power conversion systems, inverters are key components, and their performance stability and safety are crucial to the operation of the entire system. As key equipment for power conversion, inverters are widely used in various occasions, including outdoor environments.

[0003] Existing inverter wiring hole designs often lack effective waterproofing measures. Once exposed to rain or humid environments, they can easily cause short circuits or damage to electrical components, affecting the normal operation of the inverter. Additionally, when the connector is shaken or bumped, it can easily become loose, creating gaps that allow water to enter.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a waterproof mechanism for inverter wiring holes. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof mechanism for inverter wiring holes, so as to solve the problem mentioned in the background art that the connector plug is prone to loosening when shaken or bumped, resulting in gaps that allow water to enter.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof mechanism for inverter wiring holes, comprising an inverter body, wherein a wiring hole is provided on the front end face of the inverter body, a connector plug is provided inside the wiring hole, and an anti-disconnection component for the connector plug is provided on the front end face of the inverter body;

[0007] A limiting plate is fixedly connected to the outer wall of the connector plug. A first rubber ring is fixedly connected to the inner edge of the limiting plate. A plug is fixedly connected to the inner wall of the limiting plate. A second rubber ring is fixedly connected to the front end of the plug. A conical block is fixedly connected to the front end of the second rubber ring. A slot corresponding to the plug is opened on the front end face of the inverter body.

[0008] Furthermore, a third rubber ring is fixedly connected to the inner wall of the slot, and the inner wall of the third rubber ring is provided with a tapered groove.

[0009] Furthermore, the anti-detachment component includes a first stop block fixedly connected to both sides of the connector plug, the first stop block having a triangular structure.

[0010] Furthermore, a fixing plate is fixedly connected to the edge of the front end face of the inverter body, and a sliding plate is provided on the inner wall of the fixing plate. A second stop is slidably connected inside the sliding plate.

[0011] Furthermore, a spring is fixedly connected to the left side wall of the second stop.

[0012] Furthermore, an L-shaped push rod is fixedly connected to the upper end of the second stop.

[0013] Furthermore, a rainproof baffle is fixedly connected to the front end of the drainage block, and an inclined drainage groove is provided on the surface of the drainage block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Firstly, this utility model uses a limiting plate on the outer wall of the connector plug to prevent excessive insertion, ensuring a stable connection. Simultaneously, the connector plug adheres to the outer wall of the inverter body via the first rubber ring on the limiting plate, forming a preliminary sealing layer that effectively prevents external moisture and impurities from entering. The rubber material has good elasticity and sealing properties, ensuring a tight fit when the plug is inserted, improving waterproofing. Then, the plug block, fixedly connected to the inner wall of the limiting plate, is inserted into the corresponding slot on the front face of the inverter body. The second rubber ring and conical block at the front of the plug block engage tightly with the third rubber ring and conical groove inside the slot. This tight fit between the plug block and the slot enhances the stability of the connection. During insertion, the second rubber ring and conical block at the front of the plug block engage tightly with the third rubber ring and conical groove inside the slot, further improving the tightness and stability of the connection, forming a more reliable waterproof and dustproof barrier. This effectively prevents external moisture, dust, and other impurities from entering the inverter through the wiring holes.

[0016] Secondly, when the connector plug is connected to the inverter body through the wiring hole, the first stop and the second stop on the outer wall of the connector plug come into contact. The second stop is compressed along the upper and lower sliding plates by the spring. When the connector plug is inserted, the first stop is located on the rear side wall of the second stop. The second stop is blocked by the restoring elasticity of the spring, which effectively prevents the plug from accidentally falling off under the action of external force, enhances the stability of the connection, and can also maintain a certain pressure through the elasticity of the spring, thereby effectively preventing external moisture from seeping into the inverter through the gaps.

Detailed Implementation

[0022] 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.

[0023] Example 1

[0024] like Figure 1 - Figure 4 As shown, a waterproof mechanism for inverter wiring holes includes an inverter body 1. A wiring hole 2 is provided on the front end face of the inverter body 1. A connector 201 is provided inside the wiring hole 2. An anti-disconnection component for the connector 201 is provided on the front end face of the inverter body 1. The connector 201 is inserted into the wiring hole 2 and connected to the inverter body 1.

[0025] A limiting plate 3 is fixedly connected to the outer wall of the connector plug 201. A first rubber ring 301 is fixedly connected to the inner edge of the limiting plate 3. A plug block 302 is fixedly connected to the inner wall of the limiting plate 3. A second rubber ring 303 is fixedly connected to the front end of the plug block 302. A conical block 304 is fixedly connected to the front end of the second rubber ring 303. A slot 4 corresponding to the plug block 302 is opened on the front end face of the inverter body 1.

[0026] Furthermore, a third rubber ring 401 is fixedly connected to the inner wall of slot 4. The inner wall of the third rubber ring 401 has a tapered groove 402. When the connector 201 is inserted, the limiting plate 3 on the outer wall of the connector 201 blocks the insertion, preventing excessive depth and ensuring a stable connection. Simultaneously, the connector 201 adheres to the outer wall of the inverter body 1 via the first rubber ring 301 on the limiting plate 3, forming a preliminary sealing layer that effectively prevents external moisture and impurities from entering. The rubber material has good elasticity and sealing properties, ensuring a tight fit when the connector is inserted, improving waterproofing. Then, the plug block 302 fixedly connected to the inner wall of the limiting plate 3 moves along the inverter... The plug 302 is inserted into the slot 4 on the front end of the main body 1. The second rubber ring 303 and the conical block 304 at the front end of the plug 302 engage tightly with the third rubber ring 401 and the conical groove 402 inside the slot 4. The tight engagement between the plug 302 and the slot 4 enhances the stability of the connection. During the insertion of the plug 302 into the slot 4, the second rubber ring 303 and the conical block 304 at the front end of the plug 302 engage tightly with the third rubber ring 401 and the conical groove 402 inside the slot, further improving the tightness and stability of the connection. This forms a more reliable waterproof and dustproof barrier, which can effectively prevent external moisture, dust and other impurities from entering the inverter through the wiring hole.

[0027] Furthermore, the anti-detachment component includes a first stop 5 fixedly connected to both sides of the connecting plug 201, the first stop 5 having a triangular structure.

[0028] Furthermore, the upper end of the second stop 603 is fixedly connected to a push rod 7 with an L-shape. When disassembling, the push rod 7 is pulled to both sides to compress the second stop 603.

[0029] Furthermore, a fixing plate 6 is fixedly connected to the edge of the front end face of the inverter body 1. A sliding plate 601 is provided on the inner wall of the fixing plate 6. A second stop 603 is slidably connected inside the sliding plate 601. A spring 602 is fixedly connected to the left side wall of the second stop 603. When the connector 201 is connected to the inverter body 1 through the wiring hole 2, the first stop 5 on the outer wall of the connector 201 contacts the second stop 603, thereby compressing the second stop 603 along the upper and lower sliding plates 601 by the spring 602. When the connector 201 is inserted, the first stop 5 is located on the rear side wall of the second stop 603. The second stop 603 is blocked by the restoring elasticity of the spring 602, effectively preventing the connector from accidentally falling off under external force, enhancing the stability of the connection, and maintaining a certain pressure through the elasticity of the spring 602, thereby effectively preventing external moisture from seeping into the inverter through gaps.

[0030] Example 2

[0031] like Figure 1 and Figure 4 As shown, the present invention proposes a waterproof mechanism for inverter wiring holes. Compared with Embodiment 1, as another embodiment of the present invention, the front end of the drain block 8 is fixedly connected to a rainproof baffle 801. The surface of the drain block 8 is provided with an inclined drain groove, which can directly block most of the direct impact of rainwater and impurities, reducing the possibility of them entering the inverter. The inclined drain groove on the surface of the drain block 8 can guide rainwater and other liquids to flow along a specific path, avoiding accumulation around the wiring hole.

[0032] Working Principle: The limiting plate 3 on the outer wall of the connector 201 prevents excessive insertion, ensuring a stable connection. Simultaneously, the connector 201 adheres to the outer wall of the inverter body 1 via the first rubber ring 301 on the limiting plate 3, forming a preliminary sealing layer that effectively prevents external moisture and impurities from entering. The rubber material has good elasticity and sealing properties, ensuring a tight fit when the connector is inserted, improving waterproofing. Then, the plug block 302, fixedly connected to the inner wall of the limiting plate 3, is inserted into the slot 4 on the front end of the inverter body 1. The second rubber ring 303 and conical block 304 at the front end of the plug block 302 engage tightly with the third rubber ring 401 and conical groove 402 inside the slot 4. This tight fit between the plug block 302 and the slot 4 enhances the stability of the connection. During the insertion of the plug 302 into the slot 4, the second rubber ring 303 and the conical block 304 at the front end of the plug 302 are tightly engaged with the third rubber ring 401 and the conical groove 402 inside the slot, further improving the tightness and stability of the connection. Then, when the connector 201 is connected to the inverter body 1 through the wiring hole 2, the first stop 5 on the outer wall of the connector 201 contacts the second stop 603, thereby compressing the second stop 603 along the upper and lower sliding plates 601 by the spring 602. After the connector 201 is inserted, the first stop 5 is located on the rear side wall of the second stop 603. The second stop 603 is restored by the elasticity of the spring 602, thereby blocking the first stop 5, effectively preventing the plug from accidentally falling off under the action of external force, and enhancing the stability of the connection.

[0033] This is the working principle of the waterproof mechanism for inverter wiring holes.

[0034] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
