Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic adapters, and in particular to a new energy photovoltaic adapter. Background Art

[0002] In the new energy photovoltaic sector, complex system architectures encompass multiple key components, including photovoltaic panels, inverters, controllers, and energy storage devices. These devices come from different manufacturers and have varying interface specifications and communication protocols. Adapters serve as a bridge, connecting the photovoltaic panel output plug to a specific adapter socket, and then connecting the adapter plug to devices such as inverters. This cleverly resolves the problem of interface mismatches and ensures smooth power transmission and data communication. They play an indispensable role in the entire new energy photovoltaic system and are widely used in various scenarios, including photovoltaic power plants, distributed photovoltaic power generation projects, and household photovoltaic systems.

[0003] In the actual use of existing adapters, many problems are exposed: on the one hand, after the existing plug is inserted, it is often difficult to unplug it, and usually requires the coordinated operation of both hands, which is extremely inconvenient to use. This seriously affects the user experience in some scenarios where one-handed operation is required or the operating space is limited; on the other hand, the contacts of the adapter socket are very likely to suffer from metal fatigue after multiple plugging and unplugging, resulting in poor contact problems, which in turn affects the normal communication connection between devices and reduces the stability and reliability of the adapter. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a new energy photovoltaic adapter to solve the above problems.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions to implement it: a new energy photovoltaic adapter, including an adapter shell, the outer surface of the adapter shell is fixedly connected to a network cable, the outer surface of the network cable is located on the inner side wall of the adapter shell and is provided with a network cable protection block, network cable sockets are provided at both ends of the adapter shell, the inner top wall of the network cable socket is provided with a plug slot, the inner side wall of the adapter shell is provided with a plug ejection module, and the inner side wall of the adapter shell is located at the lower side of the network cable socket and is also provided with a contact adjustment module.

[0006] Preferably, the plug ejection module includes a first rotating shaft, which is rotatably connected to the inner side wall of the adapter housing, the outer surface of the first rotating shaft is rotatably connected to a hand-pinch block, the inner side wall of the hand-pinch block is rotatably connected to a first connecting rod, one end of the first connecting rod is rotatably connected to a push rod, the inner side wall of the hand-pinch block is rotatably connected to a second connecting rod through a rotating shaft, one end of the second connecting rod is rotatably connected to a first push plate through an axis rod and a support ear block, a limiting groove is provided on the lower side of the outer surface of the first push plate, the inner side wall of the limiting groove is slidably connected to the limiting rod, one end of the limiting rod is fixedly connected to a stop block, the other end of the limiting rod is fixedly connected to the second push plate, and the inner side wall of the second push plate is fixedly connected to a spring.

[0007] Preferably, the contact adjustment module includes a lifting rod, the inner side wall of the network cable socket is fixedly connected with a metal sheet contact, the inner side wall of the adapter housing is located at the lower side of the network cable socket and is slidably connected with a lifting rod, the upper surface of the lifting rod is fixedly connected with a lifting block, and the lower surface of the lifting rod is provided with a limit block, and the inner side wall of the limit block is inserted with an adjustment bolt.

[0008] Preferably, the plug ejection modules are provided with two and are symmetrically arranged, the outer surface of the hand-kneading block is provided with an anti-sliding block, and there are several anti-sliding blocks, and the hand-kneading blocks are provided with two and are symmetrically arranged.

[0009] Preferably, the push rod is slidably connected to the inner side wall of the adapter housing through a sliding block, two second connecting rods are provided and are symmetrically staggered, one end of the spring abuts against the outer surface of the first push plate, and the side of the stop block close to the limit rod abuts against the side of the outer surface of the first push plate away from the second push plate.

[0011] The beneficial effects of the present invention are:

[0012] 1. The present invention changes the plug-in and pull-out method by coordinating the plug-pushing module with the adapter housing. Users can quickly pull out the plug by pinching the pinch block with two fingers, eliminating the limitation of two-handed operation. It is suitable for one-handed operation or space-constrained scenarios, such as outdoor photovoltaic power station commissioning. The anti-slip block on the pinch block increases friction to prevent hand slippage, making plugging and pulling out more stable and reliable, thereby improving user experience and work efficiency.

[0013] 2. The present invention effectively solves the problem of metal fatigue of the adapter contacts through the setting of the contact adjustment module. As the number of plugging and unplugging increases, the metal sheet contacts are prone to poor contact, affecting equipment communication. At this time, the user adjusts the bolts to raise the lifting rod and lifting block, pushing the metal sheet contacts to make them more tightly connected to the plug. This design ensures the long-term stable operation of the adapter, maintains smooth power and data transmission, extends the life of the adapter, reduces system downtime, and provides protection for the stable operation of various photovoltaic systems.

[0021] The following will describe various embodiments of the present invention in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] Example:

[0023] See also Figures 1 to 5A new energy photovoltaic adapter includes an adapter shell 1, which is characterized in that: a network cable 2 is fixedly connected to the outer surface of the adapter shell 1, and a network cable protection block 3 is provided on the inner side wall of the adapter shell 1 on the outer surface of the network cable 2. Network cable sockets 4 are provided at both ends of the adapter shell 1, and a plug slot 5 is provided on the inner top wall of the network cable socket 4. A plug ejection module is provided on the inner side wall of the adapter shell 1, and a contact adjustment module is also provided on the inner side wall of the adapter shell 1 located below the network cable socket 4.

[0024] The plug ejection module includes a first rotating shaft 6, which is rotatably connected to the inner wall of the adapter housing 1, and the outer surface of the first rotating shaft 6 is rotatably connected to the hand-pinching block 7, and the inner wall of the hand-pinching block 7 is rotatably connected to the first connecting rod 11, and one end of the first connecting rod 11 is rotatably connected to the push rod 10. The inner wall of the hand-pinching block 7 is rotatably connected to the second connecting rod 19 through the rotating shaft, and one end of the second connecting rod 19 is rotatably connected to the first push plate 12 through the shaft and the support ear block 18. A limiting groove 13 is provided on the lower side of the outer surface of the first push plate 12, and the inner side wall of the limiting groove 13 is slidably connected to the limiting rod 14, one end of the limiting rod 14 is fixedly connected to the stop block 15, and the other end of the limiting rod 14 is fixedly connected to the second push plate 16, and the inner side wall of the second push plate 16 is fixedly connected to the spring 17.

[0025] There are two plug ejection modules and they are symmetrically arranged. The outer surface of the hand-kneading block 7 is provided with an anti-sliding block 8. There are several anti-sliding blocks 8. There are two hand-kneading blocks 7 and they are symmetrically arranged.

[0026] The push rod 10 is slidably connected to the inner wall of the adapter housing 1 through the sliding block 9. Two second connecting rods 19 are provided and are symmetrically staggered. One end of the spring 17 abuts against the outer surface of the first push plate 12, and the side of the stop block 15 close to the limit rod 14 abuts against the side of the outer surface of the first push plate 12 away from the second push plate 16.

[0027] Working principle: When it is necessary to unplug the plug, the user pinches the two hand-knobs 7 with two fingers. Since the hand-knobs 7 are connected to the inner wall of the adapter housing 1 through the first rotating shaft 6, the hand-knobs 7 are rotated by force, and the rotation of the hand-knobs 7 drives the first connecting rod 11 connected to the inner wall of the adapter housing 1 to move. The first connecting rod 11 pushes the push rod 10 to slide on the inner wall of the adapter housing 1 through the sliding block 9. At this time, the push rod 10 will squeeze the limit card on the plug to disengage it from the plug slot 5. At the same time, the second connecting rod 19 connected to the inner wall of the hand-knob 7 through the rotating shaft also rotates with it, and the second connecting rod 19 drives the second connecting rod 19 connected to it The first push plate 12 moves, and the limiting groove 13 opened on the lower side of the outer surface of the first push plate 12 slides along the limiting rod 14. The stopper 15 fixed at one end of the limiting rod 14 limits the movement range of the first push plate 12 to prevent it from excessive displacement. When the first push plate 12 moves, the spring 17 fixed to the inner wall of the second push plate 16 is compressed. Under the action of the elastic force of the spring 17 and the first push plate 12, the second push plate 16 moves toward the direction close to the plug, thereby pushing the plug out of the network cable socket 4. The anti-sliding block 8 on the outer surface of the hand-holding block 7 increases the friction between the finger and the hand-holding block 7, ensuring a stable operation process and avoiding hand slippage.

[0028] See also Figure 2 、 Figure 4 and Figure 6 A new energy photovoltaic adapter includes an adapter shell 1, which is characterized in that: a network cable 2 is fixedly connected to the outer surface of the adapter shell 1, and a network cable protection block 3 is provided on the inner side wall of the adapter shell 1 on the outer surface of the network cable 2. Network cable sockets 4 are provided at both ends of the adapter shell 1, and a plug slot 5 is provided on the inner top wall of the network cable socket 4. A plug ejection module is provided on the inner side wall of the adapter shell 1, and a contact adjustment module is also provided on the inner side wall of the adapter shell 1 located below the network cable socket 4.

[0029] The contact adjustment module includes a lifting rod 21, the inner wall of the network cable socket 4 is fixedly connected to the metal sheet contact 20, the inner wall of the adapter housing 1 is located at the lower side of the network cable socket 4 and is slidably connected to the lifting rod 21, the upper surface of the lifting rod 21 is fixedly connected to the lifting block 22, the lower surface of the lifting rod 21 has a limit block 23, and the inner wall of the limit block 23 is inserted with an adjustment bolt 24.

[0030] There are several metal sheet contacts 20 and they are evenly distributed in a rectangular array. There are several lifting blocks 22 and they are evenly distributed in a rectangular array. The upper surface of the lifting block 22 abuts against the lower surface of the metal sheet contact 20. The outer surface of the adjusting bolt 24 is threadedly connected to the inner side wall of the lower side of the adapter housing 1. The lifting block 22 is electrically connected to the network cable 2 through a wire.

[0031] Working principle: As the number of times the plug is plugged in and out increases during the use of the adapter, the metal sheet contact 20 on the inner wall of the network cable socket 4 may have poor contact due to metal fatigue. At this time, the user can improve the contact effect by adjusting the adjusting bolt 24. The outer surface of the adjusting bolt 24 is threadedly connected to the inner wall of the lower side of the adapter housing 1. When the adjusting bolt 24 is rotated, the limit block 23 on the lower surface of the lifting rod 21 is sleeved on the adjusting bolt 24. The lifting rod 21 will slide upward on the inner side of the adapter housing 1 at the lower side of the network cable socket 4, and the lifting block 22 fixed on the upper surface of the lifting rod 21 will rise accordingly. The lifting block 22 abuts against the lower surface of the metal sheet contact 20, pushing the metal sheet contact 20 upward, making the connection between the metal sheet contact 20 and the plug tighter and restoring a good contact state. The lifting block 22 is electrically connected to the network cable 2 through a wire, ensuring that current can be smoothly transmitted through the metal sheet contact 20, maintaining smooth power transmission and data communication between devices, and ensuring long-term stable operation of the adapter.

[0032] In summary, when using the entire device: To unplug the new energy photovoltaic adapter, the user pinches the knob 7 with two fingers. Rotating the knob 7 drives the first connecting rod 11 to slide the push rod 10. Simultaneously, the second connecting rod 19 drives the first push plate 12. The first push plate 12 slides along the limit rod 14 through the limit slot 13 and compresses the spring 17, causing the second push plate 16 to push the plug out of the network cable socket 4. The anti-slider 8 ensures stable operation. If the metal contact 20 becomes loose due to repeated plugging and unplugging, the user rotates the adjustment bolt 24, driving the lifting rod 21 upward, causing the lifting block 22 to push the metal contact 20 upward, thereby tightening the connection between the metal contact 20 and the plug, ensuring smooth power and data transmission and maintaining stable operation of the adapter.
