Description

Technical Field

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

[0002] A photovoltaic (PV) wire harness connector is a specially designed connector for connecting PV wire harnesses. PV wire harness connectors typically feature waterproof, high-temperature resistance, cold resistance, and UV resistance, ensuring the safe and stable operation of solar energy systems. These connectors employ a special design to effectively connect different wire harnesses, including DC and AC wires, to connect solar cell modules to inverters and the power grid. PV wire harness connectors not only provide reliable connections but also feature corrosion resistance and durability, enhancing system performance and reliability. Existing connectors often use snap-fit ​​connections at both ends, which, while convenient for disassembly and installation, are prone to detachment if the snap-fit ​​breaks. Therefore, we have introduced a connector specifically designed for PV power plants. Utility Model Content

[0003] The main purpose of this invention is to provide a connector for photovoltaic power plants, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A connector for a photovoltaic power station includes a first wire harness and a second wire harness. The right end of the second wire harness is fixedly connected to a left connecting part, and the left end of the first wire harness is fixedly connected to a right connecting part. A safety ring is sleeved on the outer surface of the right connecting part.

[0006] Preferably, the right connecting part includes a second connecting head, the left end of which is fixedly connected to a mating part. A sliding groove is opened on the right side of the outer surface of the mating part. Slots are opened on the upper and lower parts of the outer surface of the mating part. Buckles are fixedly connected to the right wall of the two slots. The ends of the two buckles that are far apart from each other are protruding. Both buckles are arc-shaped structures.

[0007] By adopting the above technical solution, the buckle does not contact the front and rear groove walls of the groove, thus avoiding affecting the deformation of the buckle.

[0008] Preferably, the second connector is fixedly connected to the first wire harness.

[0009] Preferably, the left connecting part includes a first connecting head, the right end of which is fixedly connected to an outer sleeve. The upper and lower parts of the outer surface of the outer sleeve are provided with slots, and the right part of the outer surface of the outer sleeve is provided with an external thread.

[0010] Preferably, the first connector is fixedly connected to the second wire harness.

[0011] Preferably, the outer surface of the safety ring is fixedly connected with a plurality of anti-slip protrusions, the inner wall of the safety ring is provided with an internal thread, the safety ring is threadedly connected to the outer sleeve through the internal thread, and the safety ring is slidably connected to the slide groove.

[0012] By adopting the above technical solution, the safety ring is used as the main connecting component, which makes the outer sleeve and the mating part tightly connected, and the buckle can prevent them from falling off.

[0013] Preferably, the diameter of the insert portion is adapted to the inner diameter of the outer sleeve portion, and the two buckles are respectively inserted and movably connected to the two slots.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, after the insert part and the outer part are inserted, the diameter of the insert part is adapted to the inner diameter of the outer part, so that part of the insert part extends into the outer part. At this time, the two buckles fixed on the insert part are deformed inward by the pressure of the outer part. When the two buckles move to the slot position opened on the outer part, the two buckles are no longer limited by the outer part and are reset. The two buckles extend into the two slots respectively for the first limiting. Then, the safety ring is moved to the left, so that the safety ring moves in the sliding groove opened on the insert part. After the safety ring contacts the outer part, the safety ring is rotated to make the safety ring threadedly connected to the outer part for the second limiting, thereby improving the stability of the connection between the left and right connecting parts and preventing them from falling off.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A connector for a photovoltaic power station includes a first wire harness 1 and a second wire harness 2. The right end of the second wire harness 2 is fixedly connected to a left connecting part 3, and the left end of the first wire harness 1 is fixedly connected to a right connecting part 5. A safety ring 4 is sleeved on the outer surface of the right connecting part 5.

[0026] In this embodiment, the right connecting part 5 includes a second connector 51. The left end of the second connector 51 is fixedly connected to a mating part 54. A groove 53 is opened on the right side of the outer surface of the mating part 54. A slot 55 is opened on the upper and lower parts of the outer surface of the mating part 54. A buckle 52 is fixedly connected to the right wall of the two slots 55. The ends of the two buckles 52 that are far apart from each other are protruding. Both buckles 52 are arc-shaped structures. The second connector 51 is fixedly connected to the first wire harness 1.

[0027] The above solution involves inserting the mating part 54 into the outer sleeve part 32, then inserting the two clips 52 into the two slots 33 on the outer sleeve part 32 to connect the outer sleeve part 32 and the mating part 54 and perform a first limiting action. Then, the safety ring 4 on the mating part 54 is moved to make the safety ring 4 threadedly connected to the outer sleeve part 32, thus achieving a second limiting action and improving the connection stability of the entire connector.

[0028] In this embodiment, the left connecting part 3 includes a first connecting head 31, and an outer sleeve 32 is fixedly connected to the right end of the first connecting head 31. The upper and lower parts of the outer surface of the outer sleeve 32 are provided with slots 33, and the right part of the outer surface of the outer sleeve 32 is provided with an external thread 34. The first connecting head 31 is fixedly connected to the second wire harness 2. Several anti-slip protrusions 41 are fixedly connected to the outer surface of the safety ring 4. The inner wall of the safety ring 4 is provided with an internal thread 42. The safety ring 4 is threadedly connected to the outer sleeve 32 through the internal thread 42. The safety ring 4 is slidably connected to the sliding groove 53. The diameter of the insertion part 54 is adapted to the inner diameter of the outer sleeve 32, and the two buckles 52 are respectively inserted and movably connected to the two slots 33.

[0029] It should be noted that this utility model describes a connector for a photovoltaic power station. The mating part 54 is precisely inserted into the outer sleeve 32, with their diameters matching the inner diameter, ensuring that the appropriate portion of the mating part 54 smoothly extends into the outer sleeve 32. During this insertion process, two pre-set latches 52 on the mating part 54 are automatically deformed inward by the pressure of the inner wall of the outer sleeve 32 to adapt to spatial changes. When the latches 52 reach the pre-set slots 33 on the outer sleeve 32 as the mating part 54 is inserted deeper, the latches 52 immediately release the pressure, return to their original shape, and are securely embedded in their respective slots 33, achieving initial locking and enhancing the stability of the connection structure. Next, the safety ring 4 is gently pushed to the left, allowing it to slide smoothly within the groove 53 on the mating part 54 until the safety ring 4 contacts the surface of the outer sleeve 32. Subsequently, by rotating the safety ring 4, a tight and reliable threaded connection is achieved through the threaded engagement between it and the outer sleeve 32. This step, as a secondary limiting measure, further enhances the connection strength and stability between the left connecting part 3 and the right connecting part 5, effectively preventing the accidental detachment of the connecting parts and ensuring the overall structure's sturdiness and safety.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
