Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a photovoltaic connector. Background Technology

[0002] A photovoltaic connector is a device that provides a detachable and movable connection between optical fibers. It precisely aligns the two end faces of the optical fibers to maximize the coupling of light energy from the transmitting fiber to the receiving fiber and minimize the impact on the system caused by its intervention in the optical link. These are the basic requirements of photovoltaic connectors. To a certain extent, photovoltaic connectors affect the reliability and performance of optical transmission systems.

[0003] A search revealed a Chinese patent (authorization announcement number CN202404281U) disclosing a photovoltaic connector, comprising a hollow female connector and a male connector. The female connector includes a female body and an inner tube extending horizontally on the female body. Multiple latches surrounding the inner tube are also connected to the female body. The male connector includes a male body and an inner hole extending horizontally on the male body. The inner diameter of the inner hole is larger than the outer diameter of the inner tube. The male body also has multiple locking holes surrounding the inner hole that mate with the latches. In use, the female and male connectors are inserted together, the inner tube is inserted into the inner hole, the optical fiber passes through the inner tube, and the latches on the female body are inserted into the locking holes on the male body. This patented technology allows for the locking of the female and male connectors without tools, and the connection is reliable.

[0004] However, the above-mentioned devices still have some drawbacks in actual use. The most obvious one is that the photovoltaic connector adopts a clamp and a clamp hole fixing method. The single fixing point design may create a single point of failure risk in large-scale power plants. Once the fixing point fails due to external force or material aging, it will directly lead to the collapse of the reliability of the entire connection system. This risk is particularly prominent in large-scale photovoltaic power plants. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main objective of this utility model is to provide a photovoltaic connector.

[0006] The technical solution of this utility model is as follows: A photovoltaic connector includes a connector a, a connector b is provided on one side of the connector a, a connector terminal is fixedly connected to the side of the connector a near the connector b, a protruding ring is fixedly connected to the outer periphery of the connector terminal, a fixing ring is fixedly connected to the side of the connector b near the connector a, a locking hole is equidistantly opened inside the fixing ring, a steel ball is provided inside each locking hole, a groove is opened inside the fixing ring, a sliding ring is slidably connected to the outer wall of the groove, and several steel balls abut against the inner wall of the sliding ring and the outer wall of the connector terminal.

[0007] By adopting the above technical solution, the sliding ring can be pushed to slide in the groove by the action of the spring in the clamping component, which in turn can push the steel ball to abut against the outer wall of the connecting terminal, so that it is not easy to fall off under the locking of the protruding ring.

[0008] In a preferred embodiment, the interior of the groove is provided with a clamping component, which includes a spring sleeved on the outer periphery of the fixed ring and disposed between the sliding ring and the inner wall of the groove.

[0009] By adopting the above technical solution, by pushing the sliding ring, multiple steel balls can no longer come into contact with the outer wall of the connecting terminal, thus making it easier for workers to remove the connecting terminal and the protruding ring from the fixed ring.

[0010] In a preferred embodiment, a snap-fit ​​assembly is provided on the outer side of the connector b. The snap-fit ​​assembly includes two snap-fit ​​pieces fixedly connected to the outer side of the connector a. A snap-fit ​​groove is provided inside the connector b to cooperate with the snap-fit ​​pieces.

[0011] By adopting the above technical solution and using the snap-fit ​​connector and snap-fit ​​slot together, it is convenient for workers to quickly connect connector a and connector b.

[0012] In a preferred embodiment, the two snap-fit ​​components are respectively disposed on both sides of the connecting terminal, and each snap-fit ​​component is snapped into the corresponding snap-fit ​​groove.

[0013] By adopting the above technical solution and setting the connection terminals, the docking purpose can be achieved.

[0014] In a preferred embodiment, the connector a and connector b are provided with a sealing assembly inside. The sealing assembly includes a sealing ring fixedly connected to the outside of the fixing ring, and the connector a has a sealing groove inside that cooperates with the sealing ring.

[0015] By adopting the above technical solution, the sealing performance between connector a and connector b can be improved through the combined use of the sealing ring and the sealing groove.

[0016] In a preferred embodiment, a fixing handle is fixedly connected to both sides of the sliding ring, and the steel ball is disposed on one side of the raised ring.

[0017] By adopting the above technical solution and setting a fixed handle, the sliding ring can be pushed.

[0018] In a preferred embodiment, the outer walls of both connector a and connector b are coated with an anti-oxidation paint coating.

[0019] By adopting the above technical solution and setting an anti-oxidation paint coating, the material can be isolated from contact with oxygen, moisture and other corrosive substances.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, the sliding ring can be pushed to slide in the groove by the action of the spring in the clamping component, which in turn can push the steel ball to abut against the outer wall of the connecting terminal. In this way, it is not easy to fall off under the locking of the protruding ring. It can achieve a double fixing effect on the basis of the fixing of the snap-fit ​​component, thereby improving the connection stability of connector a and connector b and making it less likely to form a single point of failure risk.

[0022] 2. In this utility model, after connector a and connector b are connected, the sealing ring at the fixing ring will always engage with the sealing groove inside connector a, thereby improving the sealing performance between connector a and connector b. When it is necessary to unlock the inside of connector a and connector b, the sliding ring can be pushed to the spring to compress, so that multiple steel balls no longer abut against the outer wall of the connector terminal, thus making it easier for the staff to remove the connector terminal and the protruding ring from the fixing ring.

[0028] The technical solutions in 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. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-4 A photovoltaic connector includes a connector a1, a connector b2 on one side of connector a1, a connector terminal 6 fixedly connected to the side of connector a1 near connector b2, a protruding ring 7 fixedly connected to the outer periphery of connector terminal 6, and a fixing ring 12 fixedly connected to the side of connector b2 near connector a1. The fixing ring 12 has equidistantly spaced locking holes 11, each containing a steel ball 14. The fixing ring 12 has a groove 13 inside, and a sliding ring 9 is slidably connected to the outer wall of the groove 13. Several steel balls 14 abut against the inner wall of the sliding ring 9 and against the outer wall of the connector terminal 6. During the docking process, the connecting terminal 6 on connector a1 can be inserted into connector b2, so that both the connecting terminal 6 and the protruding ring 7 are inside the fixing ring 12. At this time, through the action of the spring 10 in the clamping assembly, the sliding ring 9 can be pushed to slide in the groove 13, which in turn can push the steel ball 14 to abut against the outer wall of the connecting terminal 6. Thus, under the locking of the protruding ring 7, it is not easy for it to fall off. On the basis of the fixing of the snap-fit ​​assembly, a double fixing effect can be achieved, thereby improving the connection stability of connector a1 and connector b2 and reducing the risk of single-point failure.

[0030] Specifically, the interior of the groove 13 is equipped with a clamping component, which includes a spring 10 sleeved on the outer periphery of the fixing ring 12. When it is necessary to unlock the interior of connector a1 and connector b2, the sliding ring 9 can be pushed to press against the spring 10, so that the multiple steel balls 14 no longer abut against the outer wall of the connector terminal 6, thereby making it easier for the operator to remove the connector terminal 6 and the protruding ring 7 from the fixing ring 12. The spring 10 is located between the sliding ring 9 and the inner wall of the groove 13. The outer side of connector b2 is equipped with a snap-fit ​​component, which includes two snap-fit ​​pieces 4 fixedly connected to the outer side of connector a1. The interior of connector b2 is provided with a snap-fit ​​groove 3 that cooperates with the snap-fit ​​pieces 4. Through the cooperation of the snap-fit ​​pieces 4 and the snap-fit ​​groove 3, the operator can easily achieve the purpose of quick docking between connector a1 and connector b2. The two snap-fit ​​pieces 4 are respectively located on both sides of the connector terminal 6, and each snap-fit ​​piece 4 is engaged with the corresponding snap-fit ​​groove 3.

[0031] Specifically, connectors a1 and b2 are equipped with sealing components inside. The sealing components include a sealing ring 8 fixedly connected to the outside of the fixing ring 12. After connectors a1 and b2 are connected, the sealing ring 8 at the fixing ring 12 will always engage with the sealing groove 15 inside connector a1, thereby improving the sealing performance between connectors a1 and b2. The inside of connector a1 is provided with a sealing groove 15 that works with the sealing ring 8. Fixing handles 5 are fixedly connected to both sides of the sliding ring 9. The fixing handles 5 are used to push the sliding ring 9. The steel ball 14 is located on one side of the protruding ring 7. The outer walls of connectors a1 and b2 are coated with an anti-oxidation paint coating. Through physical isolation, a stable protective structure can be formed to isolate the material from contact with oxygen, moisture and other corrosive substances, reducing the probability of oxidation reaction.

[0032] Working principle: First, the operator can insert the connecting terminal 6 on connector a1 into connector b2, so that both the connecting terminal 6 and the protruding ring 7 are inside the fixing ring 12. At this time, the snap-fit ​​component 4 is engaged with the corresponding snap-fit ​​groove 3, thereby achieving the peripheral fixation effect between connector a1 and connector b2. Subsequently, through the action of spring 10, the sliding ring 9 can be pushed to slide in the groove 13, thereby pushing the steel ball 14 to abut against the outer wall of the connecting terminal 6. Thus, under the locking of the protruding ring 7, it is not easy for it to fall off. Based on the fixation of the snap-fit ​​component, double... The fixed ring 12 provides a strong fixing effect, thereby improving the connection stability of connectors a1 and b2. When it is necessary to unlock the inside of connectors a1 and b2, the sliding ring 9 can be pushed against the spring 10, so that the multiple steel balls 14 no longer abut against the outer wall of the connector terminal 6. This makes it easier for the operator to remove the connector terminal 6 and the protruding ring 7 from the fixing ring 12. After connectors a1 and b2 are connected, the sealing ring 8 at the fixing ring 12 will always engage with the sealing groove 15 in connector a1, thereby improving the sealing performance between connectors a1 and b2.
