The photoelectric conversion device usually uses the photovoltaic effect principle of semiconductor devices for photoelectric conversion. The connection component required in the photoelectric conversion process is a photovoltaic connector.

[0003] The existing photovoltaic connector includes a male end housing, a female end housing, a male terminal, and a female terminal. The male terminal is assembled in the male end housing, and the female terminal is assembled in the female end housing. The male end housing and the female end housing are plugged together, and the male terminal and the female terminal are plugged together.

[0004] Since photovoltaic products are mostly used in the western deserts and Gobi, which are vast areas with sufficient sunlight and sparsely populated, but due to the harsh environment in these areas, photovoltaic equipment will be invaded by wind and sand before assembly and use, and sand will be stuck in some small and narrow gaps in the photovoltaic equipment, making it difficult to clean and use. In particular, if the live connecting components of photovoltaic connectors are taken out of the package before use and are not connected and installed as soon as possible, the inside and outside of the plug-in ends will be covered with sand and accumulated. If the sand is not cleaned up and connected directly, it will cause arcing with the sand during the power transmission process, thereby damaging the photovoltaic connector. Therefore, a corresponding protective cap needs to be provided, but the existing male protective cap and the male connector are not sealed tightly enough, and are not suitable for sandy environments and are easy to get sand. Utility Model Content

[0011] In one of the embodiments, a first end cover is provided at one end of the male cap facing away from the male connector, and the first end cover forms an outwardly convex step structure in the radial direction of the male cap.

[0012] In a second aspect, the utility model provides a connector protection kit, including a female head protection component and a male head protection component, wherein the female head protection component includes:

[0013] A female connector, which is used to mate with the male connector of the male protection assembly;

[0030] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments.

[0031] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] Example 1

[0033] See also Figure 1 and Figure 2 A male head protection assembly comprises a male head connector 10 and a male head cap 20 which are detachably connected and plugged together. One end of the male head connector 10 is a columnar plug-in end 11. The outer periphery of the plug-in end 11 is provided with at least one prism surface 12. The prism surface 12 is a plane and parallel to the axis of the plug-in end 11. The male head cap 20 is provided with a snap-in hole 21. A first sealing ring 22 is provided in the snap-in hole 21.

[0034] When the male cap 20 is plugged into the male connector 10 , the first sealing ring 22 seals the plug end 11 .

[0035] The beneficial effects of this embodiment are as follows: by setting the male connector 10 and the male cap 20 as a detachable structure, the plug-in end 11 of the male connector 10 is protected and the removal of the male cap 20 is also facilitated; a prism surface 12 parallel to the axis is set on the plug-in end 11. Compared with the plug-in end 11 of the cylindrical structure in the ordinary structure that squeezes the sealing ring to deform, when the prism surface 12 of the present application squeezes the first sealing ring 22, since the first sealing ring 22 needs to be deformed and fits and seals with the prism surface 12, the deformation of the first sealing ring 22 of the present application is larger, so that the sealing effect after the prism surface 12 and the first sealing ring 22 are fitted is better; in addition, the prism surface 12 can play an anti-rotation effect, thereby preventing the plug-in end 11 and the male cap 20 from bringing in sand and soil due to relative rotation, enhancing the tightness of the clamping between the plug-in end 11 and the male cap 20, and playing a role in strengthening the sealing; in summary, the sealing effect of the present application is good and can be applied to harsh environments such as sand and soil.

[0036] On the basis of the above embodiment, the prism surface 12 can penetrate the entire axial direction of the plug end 11, and the prism surface 12 is long enough to ensure the sealing effect of the plug end 11; in specific settings, the plug end 11 can be a regular cylinder, and the prism surface 12 is a section along the axial direction of the plug end 11, so the prism surface 12 can be a regular rectangular plane. The first sealing ring 22 can be deformed to a certain extent, so that the plug end 11 and the male cap 20 fit tightly and form an interference fit structure, so the inner diameter of the first sealing ring 22 is smaller than the outer diameter of the plug end 11.

[0037] Example 2

[0038] See also Figure 1 and Figure 2 Preferably, based on Embodiment 1, an even number of prism surfaces 12 are provided and are evenly distributed: wherein the prism surfaces 12 are arranged in parallel in pairs.

[0039] The beneficial effect of adopting the preferred scheme in the above embodiment is that the prismatic surfaces 12 are evenly and symmetrically arranged, so that when the male cap 20 is sealed, the force on the first sealing ring 22 is balanced, and the multiple prismatic surfaces 12 enhance the anti-rotation and sealing effects; the symmetrically arranged prismatic surfaces 12 make the processing and manufacturing of the plug-in end 11 convenient due to its symmetrical structure.

[0040] On the basis of the above embodiment, the prism surfaces 12 are specifically evenly distributed along the radial direction of the plug-in end 11 ; and the distance between two parallel prism surfaces 12 is greater than the inner diameter of the first sealing ring 22 .

[0041] Example 3

[0042] See also Figure 2 Preferably, on the basis of Embodiment 1-2, the first sealing ring 22 is arranged in the middle of the snap-in hole 21, and the snap-in hole 21 is stepped along the direction from the first sealing ring 22 to the opening end of the snap-in hole 21, and a second sealing ring 23 is arranged at the bottom of the snap-in hole 21, and the radial dimension of the second sealing ring 23 is greater than the radial dimension of the first sealing ring 22.

[0043] The beneficial effect of adopting the preferred scheme in the above embodiment is that since a second sealing ring 23 is also provided at the bottom of the snap-in hole 21, and the diameter of the second sealing ring 23 is larger than that of the first sealing ring 22, when the end of the plug-in end 11 enters the second sealing ring 23, the end of the first sealing ring 22 close to one end of the second sealing ring 23 is pressed on the plug-in end 11, and also has a stop effect, which can prevent the plug-in end 11 from withdrawing from the snap-in hole 21, thereby improving the sealing effect of the male cap 20 on the plug-in end 11 of the male connector 10.

[0044] On the basis of the above embodiment, the clamping hole 21 is a stepped coaxial hole structure from the middle to the open end, and the clamping hole 21 also includes multiple coaxial circular holes from the middle to the bottom of the cylinder, wherein the inner diameter of the first sealing ring 22 is the smallest among all the coaxial circular holes, and the inner diameter of the circular hole gradually increases from the first sealing ring 22 to the open end of the clamping hole 21, so as to facilitate the insertion of the plug-in end 11 into the clamping hole 21 and to fit closely with the first sealing ring 22, and then to form a seal on the outer periphery of the plug-in end 11. A stepped sealing ring can also be arranged in the stepped section of the clamping hole 21, and the inner diameter of the outermost sealing ring is smaller than the diameter of the outer clamping part of the plug-in end 11, and the multi-layer sealing ring structure is combined to ensure the strength of the seal and prevent loosening.

[0045] Based on the above embodiments, see Figure 1 and Figure 2The other end of the male connector 10 is a first holding end 13, and the outer periphery of the first holding end 13 is a multi-turn thread structure. One end of the male connector 10 is a plug end 11 and needs to be sealed, and the other end has a thread structure and serves as the first holding end 13. The first holding end 13 facilitates the fixation of the male connector 10 during operation to prevent the male connector 10 from slipping or rotating.

[0046] Example 4

[0047] See also Figure 1 and Figure 2 Preferably, on the basis of embodiments 1-3, a first end cover 24 is provided at one end of the male cap 20 facing away from the male connector 10 , and the first end cover 24 forms an outwardly convex step structure in the radial direction of the male cap 20 .

[0048] The beneficial effect of adopting the preferred scheme in the above embodiment is that, on the one hand, the first end cover 24 seals one end of the snap-in hole 21 of the male cap 20, and on the other hand, since the first end cover 24 forms a radially protruding step structure on the male cap 20, the first end cover 24 can be used as a force-bearing part. When installing or disassembling the male cap 20 and the male connector 10, the first end cover 24 can play an auxiliary force-bearing effect, thereby facilitating the disassembly and assembly of the male cap 20 and preventing slipping.

[0049] Based on the above embodiment, the radially protruding shape of the first end cover 24 may be circular or polygonal; when the radially protruding shape of the first end cover 24 is circular, the first end cover 24 is preferably coaxially arranged with the first sealing ring 22, so that the radially protruding shape of the first end cover 24 along the male cap 20 is uniform, thereby facilitating the fixation and force of the first end cover 24.

[0052] A female connector 30, which is used to mate with the male connector 10 of the male protection assembly;

[0053] The female cap 40 is detachably and sealingly plugged onto the female connector 30 .

[0054] The beneficial effect of adopting the preferred scheme in the above embodiment is that a detachably connected female connector 30 and a female cap 40 are provided, so that the female connector 30 also has a protective female cap 40, and since the female connector 30 and the male connector 10 are also connected by plugging, the male connector 10, the male cap 20, the female connector 30 and the female cap 40 form a kit, which has a separate protective effect on the male connector 10 and the female connector 30.

[0055] On the basis of the above embodiments, the use principle of this embodiment is as follows: when installing the photovoltaic connector, due to the special use of the connector itself, it needs to be taken out of the package in advance before docking. After the cable is connected to the wiring end of the connector, the connected cable can no longer be completely stored in the package for sand and dust prevention; therefore, the present application provides a protective cap that can protect the male and female heads of the photovoltaic connector plug end 11 at this time, and the protective caps are separately arranged and divided into a male cap 20 and a female cap 40. The male cap 20 alone has a dust-proof and sealed protection effect on the connection end of the male connector 10, and the female cap 40 alone has a dust-proof and sealed protection effect on the connection end of the female connector 30; in summary, before the photovoltaic connector is docked, the male cap 20 and the female cap 40 can respectively prevent sand from invading the male connector 10 and the female connector 30; during docking, the male cap 20 and the female cap 40 are removed respectively, and then the female connector 30 and the male connector 10 are snap-connected and connected.

[0056] When setting the specific structure, the connection structure between the female connector 30 and the male connector 10 can be set to be detachable.

[0059] The beneficial effect of adopting the preferred scheme in the above embodiment is that the second end cover 41 is used to seal one end of the sealing sleeve 42, and the other end of the sealing sleeve 42 is used to extend into the female connector 30 and form a clamping and sealing structure for the female connector 30, thereby preventing foreign matter or sand from entering the female connector 30.

[0060] On the basis of the above-mentioned embodiment, the sealing sleeve 42 and the female connector 30 form an interference fit structure. Specifically, the outer diameter of the sealing sleeve 42 is greater than the inner diameter of the female connector 30 .

[0061] Example 7

[0062] See also Figure 3 and Figure 4 Preferably, on the basis of Embodiment 6, at least one third sealing ring 43 is arranged around the axial periphery of the sealing sleeve 42 , and the third sealing ring 43 protrudes outwardly along the radial direction of the sealing sleeve 42 .

[0063] The beneficial effect of adopting the preferred scheme in the above embodiment is that the third sealing ring 43 is arranged in the axial direction of the sealing sleeve 42, and when the sealing sleeve 42 and the female connector 30 are in contact, the female connector 30 is pressed by the compression deformation of the third sealing ring 43, and the connection between the female connector 30 and the sealing sleeve 42 is made tighter, so that the third sealing ring 43 and the female connector 30 form an interference fit structure, that is, the outer diameter of the third sealing ring 43 is greater than the inner diameter of the female connector 30.

[0064] On the basis of the above embodiment, the number of the third sealing rings 43 can be adjusted according to the specific sealing scenario. Preferably, there are two third sealing rings 43 and they are arranged at intervals.

[0065] Example 8

[0066] See also Figure 4 Preferably, on the basis of Embodiments 6-7, the sealing sleeve 42 is a hollow tubular structure, one end of the sealing sleeve 42 is sealed by a second end cover 41 and is provided with a first reinforcing rib 44; the first reinforcing rib 44 is fixedly connected to the second end cover 41 and / or the inner wall of the sealing sleeve 42.

[0067] The beneficial effect of adopting the preferred solution in the above embodiment is that the sealing sleeve 42 is a hollow structure, which can reduce the weight; the first reinforcing rib 44 is provided to strengthen the structural strength of the female cap 40. When specifically provided, the position of the first reinforcing rib 44 has three situations: the first reinforcing rib 44 can be fixed on the second end cover 41 or the inner wall of the sealing sleeve 42, and the first reinforcing rib 44 can also be fixed on both the second end cover 41 and the inner wall of the sealing sleeve 42. In addition, the first reinforcing rib 44 can be cross-shaped.

[0071] Example 10

[0072] Based on embodiments 1-9, a photovoltaic assembly is provided, including a male connector 10 of a male protection assembly, and a female connector 30 of a female protection assembly included in a connector protection kit.

[0073] On the basis of the above embodiment, the second end cap 41 is teardrop-shaped and includes a large end and a small end. The large end is provided with a large arc structure, the center of which coincides with the circle of the sealing sleeve 42. The small end is provided with a small arc structure, and the pull ring hole 45 is located at the center of the small arc structure. The distance between the center of the pull ring hole 45 and the center of the sealing sleeve 42 is greater than the outer diameter of the female connector 30 close to the female cap 40. The pull ring hole 45 can be used to install the pull ring, which can facilitate the quick removal of the female cap 40, prevent the occurrence of jamming, and improve the efficiency of connector docking.

[0075] When using the male and female head protection kit of the present application, the male connector 10 and the female connector 30 can be sealed and protected to protect the unplugged photovoltaic connector from the influence of complex environment and pollution, thereby ensuring the subsequent long-term stable and reliable connection of the photovoltaic connector. Through small accessories, big benefits can be achieved. The male cap 20 and the female cap 40 are two types of connector protection caps that can effectively protect the photovoltaic connector, reduce the unnecessary system-end after-sales caused by the inability to plug in the connector after being contaminated, reduce the temperature rise and fire risk caused by the contamination of the connector, and avoid the reduction of connector reliability caused by corrosion pollution. Therefore, before docking the male connector 10 and the female connector 30, it is only necessary to first connect the wiring terminals of the female connector 30 and the male connector 10 to complete the docking of the cables. When the female connector 30 and the male connector 10 need to be docked, the female cap 40 and the male cap 20 are quickly pulled out, and then the female connector 30 and the male connector 10 are docked and plugged. This will minimize the entry of sand and soil into the interior of the plug-in ends 11 of the two, and will not cause the accumulation of pollutants such as sand and soil at the working position of the plug-in end 11 during storage, transportation and wiring.
