Description

Technical Field

[0001] This application relates to the field of connector component technology, and in particular to a backstop structure for a photovoltaic connector. Background Technology

[0002] Photovoltaic connectors are key components in photovoltaic power generation systems, used to connect photovoltaic modules, inverters, combiner boxes and other equipment to ensure efficient current transmission and withstand harsh environments.

[0003] The published patent document CN214506992U discloses a locking structure for a photovoltaic connector, including a connector body and a nut. A threaded sleeve is fixed to the terminal of the connector body. The inner wall of the nut has a thread and a groove sequentially formed, with the thread matching the threaded sleeve. The nut and threaded sleeve are detachably connected. An elastic element is provided between the threaded sleeve and the nut, and the elastic element is detachably connected to the groove. Several locking teeth are circumferentially fixed on the end face of the threaded sleeve near the elastic element, and several locking teeth are circumferentially fixed on the outer edge of the elastic element. The locking teeth on the threaded sleeve match the locking teeth on the elastic element, and the threaded sleeve and elastic element are detachably connected. This invention achieves triple locking through the engagement of the threaded sleeve and nut, the locking teeth, and the elastic element and groove. When the threaded sleeve and nut are tightened, the locking teeth work together to achieve a good locking effect. Furthermore, this invention has a simple structure and is easy to manufacture.

[0004] When using the above devices, only one end of the cable can be locked, which may result in an unstable fixing effect, leading to unstable connection at the photovoltaic connection end and making the device unstable during use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a locking structure for photovoltaic connectors, which overcomes the deficiencies of existing technologies. It aims to solve the problem that the above-mentioned devices in the prior art can only lock one end of the cable during use, which may result in an unstable fixing effect and may lead to unstable connection of the photovoltaic connection cable, resulting in instability during use.

[0006] To achieve the above objectives, this application provides the following technical solution: a non-retractable structure for a photovoltaic connector, comprising a fixed sleeve, clamping components on both sides of the fixed sleeve, multiple sets of mounting grooves on one side of each clamping component, a horizontal plate inside each set of mounting grooves, an inclined block and a clamping block on the outer and inner sides of each horizontal plate respectively, a connecting mechanism on both sides of the fixed sleeve, two sets of connecting mechanisms located outside the clamping components, two sets of fixing rods outside the connecting mechanisms, multiple sets of snap-fit ​​pieces at one end of each of the two sets of fixing rods, multiple sets of fixing blocks outside the fixed sleeve, through grooves inside each set of fixing blocks, slots on the outer side of each fixing block, fixing rods passing through the through grooves, and snap-fit ​​pieces snapping into the slots.

[0007] By adopting the above technical solution and setting a fixed sleeve, the photovoltaic connecting wire is passed through the fixed sleeve and the two sets of connecting mechanisms during use. At this time, the connecting mechanism is slid to one side of the fixed sleeve, and the connecting mechanism will squeeze the inclined block, so that the clamping block abuts against the photovoltaic connecting wire inside. This can fix the two ends of the internal cable, keeping the cable stable inside the fixed sleeve and connecting mechanism. After fixing, the external snap-fit ​​piece of the fixing rod can be directly inserted into the inside of the snap-fit ​​slot to achieve the fixing effect of the two sets of connecting mechanisms. In this way, during use, the cable can be fixed simply by sliding the connecting mechanism to one side of the fixed sleeve. At the same time, the connecting mechanism can be fixed by the external fixing rod and fixing block, making subsequent disassembly and installation more convenient and improving the practicality of the device.

[0008] As a preferred technical solution of this application, the connecting mechanism includes a connecting sleeve and a threaded sleeve. One end of the connecting sleeve is rotatably connected to the threaded sleeve. The clamping assembly is provided with threads on the outside, and the inside of the threaded sleeve is connected to the external threads of the clamping assembly.

[0009] By adopting the above technical solution and setting up a connecting mechanism, during use, the connecting mechanism can be gradually moved closer to the fixed sleeve by rotating the threaded sleeve. This makes the clamping effect on the cable more stable and precise. At the same time, it can cooperate with the fixed rod to further improve the locking effect and play a better role in preventing backlash.

[0010] As a preferred technical solution of this application, a reinforcing groove is provided on one side of each of the multiple sets of snap-fit ​​pieces, a fixing groove is provided above the fixing block, and a fixing pin is provided inside the fixing groove.

[0011] By adopting the above technical solution and setting a reinforcing groove, the snap-fit ​​piece can be fixed by inserting a fixing pin during use, thereby further improving the stability of the device.

[0012] As a preferred technical solution of this application, both sets of the connecting mechanisms are provided with side fixing rings on their outer sides, and both sets of the side fixing rings are provided with rubber rings inside.

[0013] By adopting the above technical solution and setting a side fixing ring, one end of the two sets of connecting mechanisms can be blocked during use. At the same time, the rubber ring can better clamp the cable and also play a certain sealing role.

[0014] As a preferred technical solution of this application, a connecting ring is fixedly connected to the side of the threaded sleeve near the connecting sleeve, and a connecting groove is provided on one side of the connecting sleeve.

[0015] By adopting the above technical solution and setting a connecting ring, the connection effect between the threaded sleeve and the connecting sleeve can be improved during use, further enhancing the stability of the device during use.

[0016] As a preferred technical solution of this application, one end of each of the two sets of connecting mechanisms is fixedly connected with a threaded ring, and the side fixing ring is threadedly connected to the threaded ring.

[0017] By adopting the above technical solution and setting a threaded ring, the connection effect between the side fixing ring and the connecting mechanism can be improved during use, making disassembly and installation more convenient.

[0018] As a preferred technical solution of this application, the distance between the multiple sets of clamping components is the same, and the bottom of the multiple sets of clamping blocks is provided with a buffer pad.

[0019] By adopting the above technical solution and setting a buffer pad, the clamping effect on the internal photovoltaic connection wires can be further improved during use, while also providing a certain anti-slip and stabilizing effect.

[0020] As a preferred embodiment of this application, the inner wall of the connecting sleeve abuts against the outer side of the clamping assembly, and the size of the fixing rod matches the size of the through groove.

[0021] By adopting the above technical solution, and by setting the inner wall of the connecting sleeve to abut against the outside of the clamping assembly, the clamping stability can be further ensured. The size of the fixing rod and the size of the through groove are matched to further improve the stability of the snap-fit ​​and prevent the phenomenon of shaking and displacement.

[0022] The beneficial effects of this application are:

[0023] 1. By setting a fixed sleeve, during use, the photovoltaic connecting wire is passed through the fixed sleeve and two sets of connecting mechanisms. At this time, the connecting mechanism is slid to one side of the fixed sleeve. The connecting mechanism will squeeze the inclined block, so that the clamping block abuts against the photovoltaic connecting wire inside. This can fix the two ends of the internal cable, keeping the cable stable inside the fixed sleeve and connecting mechanism. After fixing, the external snap-fit ​​piece of the fixing rod can be directly inserted into the inside of the snap-fit ​​slot to achieve the fixing effect of the two sets of connecting mechanisms. In this way, during use, the cable can be fixed simply by sliding the connecting mechanism to one side of the fixed sleeve. At the same time, the connecting mechanism can be fixed by the external fixing rod and fixing block, making subsequent disassembly and installation more convenient and improving the practicality of the device.

[0024] 2. By setting up a connecting mechanism, during use, the connecting mechanism can be gradually moved closer to the fixed sleeve by rotating the threaded sleeve. This makes the clamping effect of the cable more stable and precise. At the same time, it can cooperate with the fixed rod to further improve the locking effect and play a better role in preventing backlash. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Reference Figure 1-4 A photovoltaic connector anti-retraction structure includes a fixed sleeve 1, with clamping components 4 on both sides of the fixed sleeve 1. Multiple mounting slots 401 are provided on one side of each clamping component 4. A horizontal plate 402 is provided inside each mounting slot 401. An inclined block 403 and a clamping block 404 are respectively provided on the outer and inner sides of the horizontal plate 402. Connecting mechanisms 2 are provided on both sides of the fixed sleeve 1. Two sets of connecting mechanisms 2 are located outside the clamping components 4. Two sets of fixing rods 3 are provided outside the connecting mechanisms 2. Multiple sets of snap-fit ​​pieces 301 are provided at one end of each fixing rod 3. Multiple sets of fixing blocks 5 are provided outside the fixed sleeve 1. Through slots 501 are provided inside each fixing block 5. A slot 502 is provided on the outer side of each fixing block 5. The fixing rods 3 pass through the through slots 501, and the snap-fit ​​pieces 301 snap into the slots 502. Each of the multiple sets of snap-fit ​​pieces 301 has a reinforcing groove 302 on one side, and a fixing groove 504 is provided above the fixing block 5. A fixing pin 503 is provided inside the fixing groove 504.

[0032] By setting a fixed sleeve 1, during use, the photovoltaic connecting wire passes through the fixed sleeve 1 and the two sets of connecting mechanisms 2. At this time, the connecting mechanism 2 slides to one side of the fixed sleeve 1, and the connecting mechanism 2 will press the inclined block 403, so that the clamping block 404 abuts against the internal photovoltaic connecting wire. This can fix the two ends of the internal cable, keeping the cable stable inside the fixed sleeve 1 and the connecting mechanism 2. After fixing, the external snap-fit ​​piece 301 of the fixing rod 3 can be directly inserted into the inside of the snap-fit ​​slot 502 to achieve the fixing effect of the two sets of connecting mechanisms 2. In this way, during use, the connecting mechanism 2 only needs to be slid to one side of the fixed sleeve 1 to achieve the fixing effect of the cable. At the same time, the connecting mechanism 2 can be fixed by the external fixing rod 3 and fixing block 5, making subsequent disassembly and installation more convenient and improving the practicality of the device. By setting a reinforcing groove 302, during use, the snap-fit ​​piece 301 is fixed by inserting the fixing pin 503, which can further improve the stability of the device during use.

[0033] Reference Figure 1-4The connecting mechanism 2 includes a connecting sleeve 201 and a threaded sleeve 202. One end of the connecting sleeve 201 is rotatably connected to the threaded sleeve 202. The clamping assembly 4 has threads on its exterior, and the interior of the threaded sleeve 202 is threadedly connected to the exterior of the clamping assembly 4. Both sets of connecting mechanisms 2 have side retaining rings 6 on their outer sides, and both sets of side retaining rings 6 have rubber rings 601 inside. One end of both sets of connecting mechanisms 2 is fixedly connected to a threaded ring 205, and the side retaining rings 6 and threaded rings 205 are threadedly connected. By setting the connecting mechanism 2, during use, the threaded sleeve 202 can be rotated... The connecting mechanism 2 gradually moves towards the fixed sleeve 1, which makes the clamping effect on the cable more stable and precise. At the same time, it can cooperate with the fixed rod 3 to further improve the locking effect and play a better role in preventing backlash. By setting the side fixing ring 6, one end of the two sets of connecting mechanisms 2 can be blocked during use. At the same time, the rubber ring 601 can better clamp the cable and play a certain role in sealing. By setting the threaded ring 205, the connection effect between the side fixing ring 6 and the connecting mechanism 2 can be improved during use, making disassembly and installation more convenient.

[0034] Reference Figure 1-4 A connecting ring 203 is fixedly connected to the side of the threaded sleeve 202 near the connecting sleeve 201, and a connecting groove 204 is provided on one side of the connecting sleeve 201. By setting the connecting ring 203, the connection effect between the threaded sleeve 202 and the connecting sleeve 201 can be improved during use, further enhancing the stability of the device during use. The distance between the multiple sets of clamping components 4 is the same, and the bottom of each set of clamping blocks 404 is provided with a buffer pad 405. By setting the buffer pad 405, the clamping effect on the internal photovoltaic connecting wire can be further improved during use, while also providing a certain anti-slip and stabilizing effect. The inner wall of the connecting sleeve 201 abuts against the outer side of the clamping component 4, and the size of the fixing rod 3 matches the size of the through groove 501. By setting the inner wall of the connecting sleeve 201 abuts against the outer side of the clamping component 4, the clamping stability can be further ensured. The matching size of the fixing rod 3 with the size of the through groove 501 can further enhance the stability of the clamping and prevent shaking or displacement.

[0035] Working principle: By setting a fixed sleeve 1, during use, the photovoltaic connecting wire passes through the fixed sleeve 1 and the two sets of connecting mechanisms 2. At this time, the connecting mechanism 2 slides to one side of the fixed sleeve 1, and the connecting mechanism 2 will squeeze the inclined block 403, so that the clamping block 404 abuts against the photovoltaic connecting wire inside. This can fix both ends of the internal cable, so that the cable remains stable inside the fixed sleeve 1 and the connecting mechanism 2. After fixing, the snap-fit ​​piece 301 on the outside of the fixing rod 3 can be directly inserted into the inside of the slot 502 to achieve the fixing effect of the two sets of connecting mechanisms 2. When in use, simply slide the connecting mechanism 2 towards one side of the fixed sleeve 1 to achieve the cable fixing effect. At the same time, the connecting mechanism 2 can be fixed by the external fixing rod 3 and fixing block 5, making subsequent disassembly and installation more convenient and improving the practicality of the device. By setting the connecting mechanism 2, during use, the connecting mechanism 2 can be gradually moved towards the fixed sleeve 1 by rotating the threaded sleeve 202. This can make the cable clamping effect more stable and precise. At the same time, it can cooperate with the fixing rod 3 to further improve the locking effect and play a better anti-reverse role.

[0036] Among them, by setting the reinforcing groove 302, the fixing effect of the snap-fit ​​piece 301 is achieved by inserting the fixing pin 503 during use, which can further improve the stability of the device during use. By setting the side fixing ring 6, one end of the two sets of connecting mechanisms 2 can be blocked during use, and the rubber ring 601 can better clamp the cable and also play a certain sealing role.

[0037] Meanwhile, by setting the connecting ring 203, the connection effect between the threaded sleeve 202 and the connecting sleeve 201 can be improved during use, further enhancing the stability of the device during use;

[0038] In addition, by setting the threaded ring 205, the connection effect between the side fixing ring 6 and the connecting mechanism 2 can be improved during use, making disassembly and installation more convenient; by setting the buffer pad 405, the clamping effect of the internal photovoltaic connection wire can be further improved during use, while also providing a certain anti-slip and stabilizing effect; by setting the inner wall of the connecting sleeve 201 to abut against the outside of the clamping component 4, the clamping stability can be further ensured; the size of the fixing rod 3 and the size of the through groove 501 are matched to further improve the stability of the snap-fit ​​and prevent the phenomenon of shaking and displacement.
