Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cable technology, and more specifically, to a photovoltaic cable with interface fastening function. Background Technology

[0002] Cables are typically made up of several or groups of conductors twisted together, resembling a rope. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer, giving it the characteristics of being internally energized and externally insulated.

[0003] A search revealed a prior art cable for photovoltaic power stations, with patent publication number CN222508189U. The specification states that by setting an interface connection structure, a drive motor inside the drive box can drive a rotating rod to slide horizontally via a turntable. This causes the moving sleeve to move outside the fixed tube via a push rod, enabling the moving sleeve to provide wrapping protection at the connection point between the cable body and the photovoltaic power station. The entire protection process is mechanized, thereby improving the connection effect between the cable and the power connection point of the photovoltaic power station.

[0004] However, in actual use, the two cables still lack a limiting component when connected. As a result, under prolonged shaking, the cables will gradually loosen due to the shaking, leading to low interface stability, increased contact resistance, local overheating, and consequently, low safety in use. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a photovoltaic cable with interface fastening function, so as to solve the problem that in the prior art, when two cables are connected, there is still a lack of limiting components, and the cables will gradually loosen due to shaking over a long period of time, resulting in low interface stability, increased contact resistance, local overheating, and low safety in use.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a photovoltaic cable with interface fastening function, including a plug one, a slot is provided on the left side of the plug one, a plug two is inserted into the slot, the plug two fits with the plug one, two slots are provided inside the plug two, and a locking block is locked inside the slot, the locking block is slidably connected inside the plug one.

[0007] The plug has two mounting slots inside. The end of the locking block away from the slot is fixedly connected to a mounting piece. The end of the mounting piece away from the locking block is fixedly connected to a pull rope. The other end of the pull rope is fixedly connected to a pull ring. An elastic element is sleeved on the outside of the pull rope.

[0008] The inner wall of the pull ring is fixedly connected to two sliders, the sliders have a limiting groove inside, and the inner wall of the limiting groove is fixedly connected to multiple protrusions.

[0009] The locking block is slidably connected inside the mounting groove, the mounting plate is slidably connected inside the mounting groove, the pull rope is slidably connected inside the mounting groove, and the pull ring is slidably connected outside the plug.

[0010] One end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the mounting plate.

[0011] The limiting block slides against the outside of the slider, and the limiting block is inserted into the inside of the limiting groove.

[0012] The protrusion slides against the outside of the limiting block, and the protrusion fits into the inside of the corresponding groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In the above solution, the two plugs are snapped together using a clip, which allows for quick connection and high stability of the plug connection.

[0016] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0017] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a photovoltaic cable with interface fastening function, including a plug 1, a slot 2 on the left side of the plug 1, a plug 3 inserted into the slot 2, so that the plug 1 and the plug 3 can be connected. The plug 3 fits close to the plug 1, so that the connection between the plug 1 and the plug 2 is well sealed, thereby improving the waterproof and dustproof performance. The plug 2 3 has two slots 4 inside, and a locking block 5 is locked inside the slot 4. The locking block 5 is slidably connected inside the plug 1, so that the connection between the plug 1 and the plug 2 3 is highly stable.

[0018] When it is necessary to connect two cables, plug 1 and plug 2 3 are brought together so that plug 2 3 can be inserted into the slot 2. Then, the two locking blocks 5 are moved to the same side so that the locking blocks 5 can be engaged with the inside of the slot 4. This makes the connection between plug 1 and plug 2 3 more stable, thus preventing localized heating of the cable, resulting in a longer service life, reducing maintenance costs, and making it more economical to use.

[0019] Example 2: Based on Example 1, in order to facilitate the pulling of the locking block 5, two mounting slots 6 are opened inside the plug 1. The locking block 5 is slidably connected inside the mounting slots 6, and the mounting slots 6 provide moving space for the locking block 5. The end of the locking block 5 away from the locking slot 4 is fixedly connected to the mounting piece 7. The mounting piece 7 is slidably connected inside the mounting slot 6. The mounting slot 6 limits the mounting piece 7, allowing the mounting piece 7 to slide smoothly. The end of the mounting piece 7 away from the locking block 5 is fixedly connected to the pull rope 9. The pull rope 9 is slidably connected inside the mounting slot 6. The mounting slot 6 limits the pull rope 9, preventing it from deviating when sliding. The other end of the pull rope 9 is fixedly connected to the pull ring 10. The pull ring 10 is slidably connected to the outside of the plug 1. The plug 1 limits the pull ring 10, allowing the pull ring 10 to slide smoothly. An elastic element 8 is sleeved on the outside of the pull rope 9. One end of the elastic element 8 is fixedly connected to the inner wall of the mounting slot 6, and the other end of the elastic element 8 is fixedly connected to the mounting piece 7.

[0020] When it is necessary to pull the locking block 5, by pulling the pull ring 10 to the right, the pull ring 10 pulls the pull rope 9 to the right, which in turn pulls the mounting piece 7 to the outside, causing the mounting piece 7 to compress the elastic element 8 and deform. This allows the mounting piece 7 to pull the locking block 5 into the interior of the mounting groove 6. Conversely, by releasing the pull ring 10, the elastic element 8 pushes the mounting piece 7 to the inside, which in turn pushes the locking block 5 to engage with the interior of the locking groove 4.

[0021] Example 3: Based on Example 2, in order to limit the pull ring 10, two sliders 14 are fixedly connected to the inner wall of the pull ring 10. The sliders 14 have a limiting groove 15 inside, and multiple protrusions 16 are fixedly connected to the inner wall of the limiting groove 15. Two sliding grooves 11 are opened on the outside of the plug 1. A limiting block 12 is fixedly connected to the inner wall of the sliding groove 11. The limiting block 12 slides against the outside of the slider 14, so that the slider 14 can squeeze the limiting block 12 to produce deformation. The limiting block 12 is inserted into the inside of the limiting groove 15, so that the slider 14 can be limited. Multiple grooves 13 are opened on the outside of the limiting block 12. The protrusions 16 slide against the outside of the limiting block 12, so that the protrusions 16 can be squeezed to produce deformation. The protrusions 16 fit with the inside of the corresponding grooves 13, so that the limiting block 12 fits more stably with the limiting groove 15.

[0022] When the pull ring 10 moves to the right, it causes the slider 14 to move to the right, allowing the slider 14 to slide against the outside of the limiting block 12. This causes the limiting block 12 to deform. When the right side of the slider 14 comes into contact with the inner wall of the groove 11, the limiting block 12 returns to its original position and enters the interior of the limiting groove 15. This allows the protrusion 16 to come into contact with the interior of the corresponding limiting block 12, thus allowing the limiting block 12 to come into contact with the interior of the limiting groove 15. Consequently, the limiting groove 15 and the groove 11 are limited, and the pull ring 10 is limited.

[0023] The working process of this utility model is as follows: When plug 1 needs to be connected to plug 3, pull the pull ring 10 to the right, causing the pull rope 9 to move to the right. This pull rope 9 then moves the mounting piece 7 outwards, causing the mounting piece 7 to compress the elastic element 8 and deform. This, in turn, causes the mounting piece 7 to pull the locking block 5 into the mounting groove 6, and the pull ring 10 to move the slider 14 to the right. The slider 14 then slides against the outside of the limiting block 12, causing the limiting block 12 to deform. Once the right side of the slider 14 is in contact with the inner wall of the slide groove 11, the limiting block 12 returns to its original position, entering the limiting groove 15. This allows the protrusion 16 to engage with the corresponding part of the limiting block 12, thus allowing the limiting block 12 to... The pull ring 10 is then positioned so that it fits into the inside of the limiting groove 15, thereby limiting the sliding groove 11 of the limiting groove 15 and limiting the pull ring 10. Then, the plug 1 and plug 2 3 are fitted together so that plug 2 3 can be inserted into the inside of the slot 2. At this time, the pull ring 10 is moved to the left so that the limiting block 12 can slide against the limiting groove 15, thereby allowing the limiting block 12 to disengage from the inside of the limiting groove 15. At this time, by releasing the pull ring 10, the elastic element 8 can push the mounting piece 7 to move inward, thereby allowing the mounting piece 7 to push the locking block 5 to engage with the inside of the locking groove 4, thereby allowing the plug to quickly connect and making the connection of the plug more stable, thus preventing local heating of the cable, resulting in a longer service life, reducing maintenance costs, and making it more economical to use.
