Description

Technical Field

[0001] The invention relates to the technical field of inverter housings, and in particular to a solar inverter housing capable of improving wiring safety. Background Art

[0002] The solar inverter housing is an important part of the solar inverter, which is mainly responsible for heat dissipation and protection of internal electronic components. There are multiple holes on the housing, which can facilitate the connection end of the inverter to slide out of the hole and install with the external terminal head. The inverter connection end extends out of the housing, so that the inverter can fit better in the housing, ensuring that the inverter can be stably installed in the housing, which is convenient for the safe protection of the inverter. Most of the existing terminal heads and connection ends adopt plug-in connection to adapt to different equipment structures and installation positions. After the connection end is installed with the terminal head, the terminal head and the housing are in contact. However, the space reserved for the housing and the connection end is fixed, which makes the line at the end of the terminal head easy to bend. Over time, its mechanical stress may decrease, which will gradually loosen the connection at the bent part, resulting in poor electrical contact, affecting the stability of the equipment and reducing the stable installation of the housing to the terminal.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] The present invention provides Figure 1-Figure 8 A solar inverter housing capable of improving wiring safety is shown, comprising: an inverter connection terminal 11 communicating with the interior of the housing 1 is mounted on the housing 1, and a detachable wiring head 12 is mounted on the inverter connection terminal 11;

[0035] The safety component 2 is used to keep the terminal head 12 stably connected to the shell 1. The safety component 2 includes a mounting frame 21 installed on one side of the shell 1, a safety ring 22 fixedly sleeved on the outside of the terminal head 12, and a first rotating ring 23 installed at one end of the mounting frame 21. The mounting frame 21 and the first rotating ring 23 are both sleeved on the outside of the inverter connection end 11 and the terminal head 12. A second rotating ring 24 is fixed to one end of the first rotating ring 23. Three through grooves 25 are formed between the first rotating ring 23 and the second rotating ring 24. Limiting components are provided in the three through grooves 25. The limiting components keep the terminal head 12 stably connected to the inverter connection end 11 on the shell 1. The first rotating ring 23 is provided with a gear component 3 that drives it to rotate. The mounting frame 21 is provided with two groups of ejection components 5 that match it with the gear component 3. The rotation of the gear component 3 drives the two groups of ejection components 5 to move and push the safety ring 22 to slide.

[0036] Each set of limiting components includes a protective sleeve 28 installed in the through groove 25 and a shaft rod 26 fixed to one end of the mounting frame 21. A safety arm 27 is movably installed at one end of the shaft rod 26. A slide groove for inserting the safety arm 27 is opened on one side of the protective sleeve 28. One end of the safety arm 27 extends to the outside of the slide groove and is fixed with a contact ring 29, and the outside of the contact ring 29 is in contact with the outside of the terminal head 12.

[0037] The gear assembly 3 includes a gear ring 31 fixedly sleeved on the outside of the first rotating ring 23 and a connecting column 32 fixed to one end of the mounting frame 21. A first gear 33 matching the gear ring 31 is installed on the outside of the connecting column 32. A rotating disk 34 is fixed at one end of the first gear 33. A locking assembly 4 is provided on the connecting column 32 for positioning it with the rotating disk 34.

[0038] The locking assembly 4 includes a mounting column 43 fixed at one end of the connecting column 32, a pawl 41 fixed in the rotating disk 34, and a ratchet 42 sleeved on the outside of the mounting column 43, and the ratchet 42 is meshed with the pawl 41, and a reset assembly for driving the ratchet 42 to reciprocate is provided in the mounting column 43; the reset assembly includes an adjusting threaded column 44 screwed in the mounting column 43, a limit block 47 fixed in the ratchet 42, and a limit groove 48 opened on the mounting column 43 and communicating with the interior thereof for sliding the limit block 47, a connecting ring 46 is fixed at the bottom of the limit block 47, and the connecting ring 46 is located in the mounting column 43 and rotatably connected to one end of the adjusting threaded column 44, and a spring 45 is installed between the connecting ring 46 and the mounting column 43.

[0039] When the housing is wired, the wiring head 12 is inserted into the second rotating ring 24 and the first rotating ring 23 and moved toward the inverter connection end 11. Then, the wiring head 12 passes the safety ring 22 installed on its outside through the abutment ring 29 and approaches the ejection component 5. At this time, the wiring head 12 drives the safety ring 22 to fit with the ejection component 5 during the continuous movement, and one end of the wiring head 12 is pre-inserted into the inverter connection end 11. Then, the rotating disk 34 is rotated to drive the first gear 33 to rotate along the connecting column 32. As the first gear 33 rotates, The first rotating ring 23 is meshed with the gear ring 31 to drive the first rotating ring 23 to rotate along one end of the mounting frame 21, and the first rotating ring 23 rotates to drive the second rotating ring 24 and the protective sleeve 28 to rotate. Then the protective sleeve 28 moves to drive the safety arm 27 to rotate along the shaft 26, so that the safety arm 27 slides between the slide groove and moves downward, so that the safety arm 27 moves downward to push the abutment ring 29 to approach the outside of the terminal head 12, and then the push-out assembly 5 is driven to slide under the rotation of the gear ring 31, so that the distance between the push-out assembly 5 and the safety ring 22 is increased. The terminal block 12 is adjusted to continue to be pushed to move into the inverter connection end 11, and the terminal block 12 is stably installed in the inverter connection end 11 and cannot be pushed, and the abutment ring 29 continuously approaches the outside of the terminal block 12 and abuts against it, so that the terminal block 12 is restricted on the inverter connection end 11 and the housing 1, which can ensure that the terminal block 12 is subjected to uniform force during the restriction process, thereby enhancing the mechanical stress at the terminal block 12, thereby improving the stability of the terminal block 12 and the inverter connection end 11, and enhancing the stability of the housing to the terminal. The screw threaded column 44 is rotated and adjusted to rotate it along the mounting column 43 and push the connecting ring 46 forward. At this time, the connecting ring 46 moves to drive the limit block 47 to slide along the limit groove 48, and then the ratchet 42 slides along the mounting column 43 to move into the rotating disk 34. Then the ratchet 42 and the pawl 41 are engaged and abutted, so that the terminal head 12 has additional stability, ensuring that the terminal head 12 is stably connected to the inverter connection terminal 11 on the housing 1, and improving the wiring safety of the terminal head 12 on the housing 1 and the inverter connection terminal 11.

[0040] refer to Figure 1 , Figure 2 , Figure 6 and Fig. 9 As shown, each group of ejection components 5 includes a second gear 57 rotatably connected to one end of the mounting frame 21 and meshing with the gear ring 31, a receiving seat 55 slidably mounted on one end of the mounting frame 21, and an inclined seat 52 fixed to one end of the safety ring 22, a rack 56 meshing with the second gear 57 is fixed in the receiving seat 55, a slide bar 54 is fixed to one side of the receiving seat 55, and one end of the slide bar 54 extends into the through groove 25 and is installed with a moving wheel 53, and the outside of the moving wheel 53 is in contact with the inclined seat 52; a guide plate 58 is also fixed to one side of the receiving seat 55, and a guide groove 51 for the guide plate 58 to slide is provided on one side of the mounting frame 21.

[0041] Through the above technical solution:

[0042] When the terminal head 12 needs to be taken out from the inverter connection end 11, the gear ring 31 first rotates to drive the resistance ring 29 to move, and then the resistance ring 29 and the terminal head 12 lose their resistance effect, and the gear ring 31 rotates and meshes with the second gear 57 to drive the second gear 57 to rotate along one end of the mounting frame 21 and mesh with the rack 56 to drive the receiving seat 55 to slide along one end of the mounting frame 21, and then the guide plate 58 slides synchronously along the guide groove 51. At this time, the receiving seat 55 moves to drive the slide bar 54 to slide along the through groove 25. As the slide bar 54 moves, it drives the moving wheel 53 to slide along one side of the inclined seat 52 and pushes the inclined seat 52 to move. Then the inclined seat 52 moves to push the safety ring 22 to move, so that the safety ring 22 moves and pushes The terminal head 12 moves along the direction of the force in the inverter connection end 11, and then the terminal head 12 and the safety ring 22 move along the first rotating ring 23 and the second rotating ring 24 toward the contact ring 29, so that the contact ring 29 is reset under continuous movement, and then the user pulls the terminal head 12 to separate from the inverter connection end 11, so that the terminal head 12 and the safety ring 22 pass through the contact ring 29 and are taken out along the first rotating ring 23 and the second rotating ring 24, which can reduce the force required for the user to pull and pull out the terminal head 12, which is conducive to the terminal head 12 being smoothly pulled out in the inverter connection end 11, thereby effectively loosening or falling off the terminal head 12 in the inverter connection end 11, and increasing the service life of the terminal head 12.
