Description

Technical Field

[0001] This utility model relates to the field of inverter plug-in connector technology, specifically to a detachable plug-in connector for inverters. Background Technology

[0002] Energy storage inverters in home and commercial energy storage systems can store electrical energy generated by solar panels or wind turbines for use at night or when energy production is low, helping to reduce dependence on the grid and lower energy costs. The inverter casing is often equipped with multiple connector boards. One end of the board connector connects to the circuit board inside the photovoltaic inverter, and the other end extends out of the photovoltaic inverter casing to connect to other connectors.

[0003] Traditional inverter plug-in connectors rely on friction between the plug and socket to stabilize the electrical connection, or use a locking connection. The male connector has a locking clip, and the female connector has a locking groove. The male and female connectors are connected by the locking clip and locking groove. However, the connection by friction and locking is not secure. When the connector is subjected to external pulling force, it is easy to separate the plug and socket, resulting in unstable or interrupted electrical connection. Therefore, we need to propose a detachable plug-in connector for inverters. Utility Model Content

[0004] The purpose of this utility model is to provide a detachable pluggable connector for inverters. By setting a sliding protective mechanism on the plug at the line end, waterproofing is provided when connecting the connector.

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a detachable pluggable connector for an inverter, comprising:

[0027] Inverter body 1, and multiple sets of connector board ends 2 installed on inverter body 1, each set of connector board ends 2 can be detachably connected to connector wire ends 3;

[0028] The protective structure 4 installed on the connector wire end 3 protects the connection end between the connector board end 2 and the connector wire end 3.

[0029] A locking mechanism 8 is provided on the connector plate end 2 to fix the protective structure 4. The protective structure 4 is provided with a foolproof structure 5 that is fastened to the locking mechanism 8, so as to realize convenient assembly of the protective mechanism.

[0030] The protective structure 4 includes symmetrically spliced ​​protective shells 41, and the two sets of spliced ​​protective shells 41 are fastened together by multiple sets of connecting bolts 42;

[0031] The splicing protective shell 41 is mainly formed by integral injection molding of plate end protective shell 411 and line end protective shell 412. The end of the line end protective shell 412 connected to the plate end protective shell 411 is provided with a sealing groove 413. The inner wall of the plate end protective shell 411 is provided with a guide groove 415. The guide groove 415 has a card hole 416 for installing the anti-foolproof structure 5 and the locking mechanism 8. The inner wall of the line end protective shell 412 is provided with a limit groove 414.

[0032] It is worth noting that in this embodiment, the protective structure 4 adopts a symmetrical spliced ​​protective shell 41, which is fastened by connecting bolts 42, making it easy to install and disassemble. At the same time, the plate end protective shell 411 and the wire end protective shell 412 are integrally injection molded, which ensures structural strength and sealing performance and improves the protection effect on the connector connection end.

[0033] The outer side of the connector plate end 2 is symmetrically provided with guide beams 23 for the guide groove 415 to be inserted, and the guide beams 23 are provided with hidden grooves 24 for the installation of the locking mechanism 8.

[0034] The connector wire end 3 is provided with a sheath 31, and one end of the sheath 31 is provided with a mating seat 33. A plug 34 is installed on the mating seat 33. The connector plate end 2 is provided with a socket 21 for the plug 34 to be inserted, and the connector plate end 2 is provided with a directional hole 22 located above the socket 21. A directional rod 36 inserted into the directional hole 22 is fixedly connected to the mating seat 33.

[0035] Furthermore, the guide beam 23 cooperates with the guide groove 415 to achieve rapid positioning and installation of the protective structure 4, and the directional rod 36 cooperates with the directional hole 22 to ensure that the plug 34 and the socket 21 are accurately connected, thereby improving the reliability and stability of the connection and avoiding problems such as poor contact caused by misalignment.

[0036] The locking mechanism 8 includes a spring member 81 fixedly connected to the bottom of the hidden groove 24. The upper end of the spring member 81 is fixedly connected to a locking block 82 that slides in the hidden groove 24, and one side of the locking block 82 is provided with an inclined surface that abuts against the guide groove 415.

[0037] In a further preferred embodiment, the protective structure 4 is automatically locked by the spring member 81 and the locking block 82. The spring member 81 consists of a spring and a telescopic sleeve rod. The spring provides elastic force to make the locking block 82 pop out and fit into the locking hole 416 after contacting the guide groove 415. The protective structure 4 can be quickly fixed without additional tools during installation, which is simple to operate and can prevent the protective structure 4 from falling off accidentally, ensuring connection safety.

[0038] The foolproof structure 5 includes a pressure rod 51 inserted into the outside of the splicing protective shell 41. The lower end of the pressure rod 51 is set in the card hole 416 and fixedly connected to a push block 52. The outside of the pressure rod 51 is clamped with an anti-pressure clip 53.

[0039] Preferably, the pressure rod 51 and the push block 52 can push the locking block 82 to quickly disengage from the locking hole 416, thereby facilitating the release of the restriction on the protective structure 4. The anti-pressure clamp 53 can prevent the pressure rod 51 from being accidentally pressed, avoid the protective structure 4 from being accidentally loosened, play a foolproof role, and ensure that the installation process is correct and error-free.

[0040] Two sets of limiting beams 35 are fixedly connected to the outer side of the sheath 31. The inner wall of the wire end sheath 412 slides on the limiting beams 35 through the limiting groove 414. An anti-detachment ring 32 is provided at the end of the sheath 31 away from the docking seat 33. The limiting beams 35 cooperate with the limiting groove 414 to limit the sliding range of the wire end sheath 412 and guide the movement of the protective structure 4, ensuring that the protective structure 4 is installed in an accurate position. At the same time, the anti-detachment ring 32 can prevent the protective structure 4 from detaching from the connector wire end 3, thereby improving the reliability of the connection.

[0041] It also includes a sealing ring 6 fitted on the outside of the sheath 31. Two sets of positioning holes 7 are provided on one side of the sealing ring 6. Two sets of positioning blocks 37 are provided on the side of the mating seat 33 opposite to the plug 34, which are inserted into the positioning holes 7. The sealing ring 6 is embedded in the sealing groove 413. The sealing ring 6 embedded in the sealing groove 413 can effectively prevent dust and moisture from entering the connector connection part, enhance the sealing effect, further protect the connector, and extend its service life.

[0042] In use, the plug 34 of connector wire end 3 is inserted into the socket 21 of connector board end 2, and the directional rod 36 is inserted into the directional hole 22 to achieve precise docking. Then, the splicing protective shell 41 slides along the guide beam 23 through the guide groove 415, so that the splicing protective shell 41 of the protective structure 4 is fitted on the connection part of connector board end 2 and connector wire end 3. During the sliding process, the guide groove 415 slides along the guide beam 23. After the guide groove 415 abuts against the locking block 82, it presses the spring member 81. When the locking hole 416 moves to align with the hidden groove 24, the locking block 82 of the locking mechanism 8 is ejected by the elastic force of the spring member 81 and locks into the locking hole 416, fixing the protective structure 4. The anti-pressure clamp 53 is used to prevent accidental contact with the pressure rod 51 to release the fastening of the protective structure 4.

[0043] When it is necessary to disassemble the connector wire end 3, remove the anti-pressure clamp 53 from the pressure rod 51, then press down the pressure rod 51, and the push block 52 pushes the locking block 82 out of the locking hole 416, thereby releasing the fastening of the protective structure 4, so that the protective structure 4 can be easily removed and the connector wire end 3 can be pulled out, improving the disassembly efficiency of the connector wire end 3.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
