Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application No. 63 / 363,547, filed on April 25, 2022, entitled “SOLAR CONNECTOR SELF-LOCKING DUST CAP LOCKOUT DEVICE,” the entire contents of which are hereby expressly incorporated herein by reference. Technical Field

[0003] The present application relates generally to latching systems, and more particularly to a utility scale solar power self-latching dust cap latching system. Background Art

[0004] Energy production and transmission infrastructure utilizes several cable types to transport current and / or signal data from source facilities to consumer locations. In large-scale solar power plants, cables can transport current and signal data from solar panels to other production and / or transmission equipment within the station. Cables can be arranged in underground or above-ground structures. These cables may include connectors arranged on either end of the cable for connection to adjacent cables or power generation or distribution systems, such as solar panels.

[0005] Commissioning is the process of ensuring that all systems and components of an energy production facility are designed, installed, tested, operated and maintained in accordance with set operating requirements. During commissioning, the order in which different systems are energized is critical to the safety of personnel on site. In addition, it is important for the connection points of cables and energy systems to have limited exposure to sand and dust to ensure reliable electrical connections between the connection points. In addition, the connection points of cables may be accidentally left in locations where mud or puddles may form, exposing the connectors to water, moisture and other foreign matter. In addition, due to construction schedules and supply chain reasons, the connection points of cables may be installed for up to weeks or months before being connected to the final location, which exposes them to outdoor weather such as rain or dust. Traditionally, flexible bags are used to cover the connectors of cables and energy systems to prevent connections between systems. However, these flexible bags may be easily removed or fall off, and due to exposure to weather, water may accumulate and allow dust to enter the connectors, and cause corrosion problems in the connectors, which may lead to future electrical risks.

[0067] It should be noted that the drawings are not necessarily drawn to scale. The drawings are intended to depict only typical aspects of the subject matter disclosed herein, and therefore should not be considered as limiting the scope of the disclosure. DETAILED DESCRIPTION

[0068] Certain exemplary aspects will now be described to provide an overall understanding of the principles of the structure, function, manufacture and use of the apparatus and methods disclosed herein. One or more examples of these aspects are shown in the accompanying drawings. It will be appreciated by those skilled in the art that the apparatus and methods specifically described herein and shown in the accompanying drawings are non-limiting exemplary aspects and that the scope of the present invention is limited only by the claims. The features shown or described in conjunction with an exemplary aspect may be combined with features of other aspects. Such modifications and variations are intended to be included within the scope of the present invention.

[0069] Energy production and transmission infrastructure utilizes several cable types to transport current, signal data, and ground paths from source facilities to consumer locations. In large-scale solar power plants, cables can transport current, signal data, and ground paths from solar panels to other production and / or transmission equipment within the station. In addition, traditional solar panels are typically attached to single-axis solar trackers that rotate the solar panels from east to west throughout the day so that the solar panels follow the sun, thereby maximizing their energy output. The cables to these solar panels can be arranged in underground or above-ground structures.

[0070] Energy generation and transmission infrastructure utilizes several cable connections to carry electricity from source facilities to consumer locations. In large-scale solar power plants, cables and connectors carry the electricity from the solar panels to other harness cables and / or transmission equipment within the station. The cables are laid out above ground, close to the solar panels, typically in locations that are easily accessible to humans.

[0071] Above-ground cable configurations, such as those used in utility-scale solar power generation and transmission systems, can be deployed using manual electrical connections with "plug-and-play" connectors so that electrical connections can be made by easily coupling male and female connectors to each other by hand. These connections must be powered on and connected in a specific sequence to avoid electric shock and pose additional safety risks. To prevent such situations, a locking device can be used to prevent the connectors from being electrically coupled together until the locking device is removed with a tool. In addition, to help prevent electrical safety risks, the locking device can have a feature such that a safety tag can be coupled to the locking device, which will warn uninformed installers not to attempt to electrically couple the connectors.

[0072] The solar connector self-locking dust cap closure devices disclosed herein are generally a single component having the following: a feature (plug or cap) to prevent dust ingress, a locking feature to prevent the connector from electrically coupling to another connector, a self-locking feature that requires the use of a tool to unlock and remove the device, and a tag attachment function that allows a security tag to be coupled to the device. In some aspects, the tag attachment feature can act as a tamper indicator feature by breaking if an installer attempts to remove the tag or closure device with force or incorrectly. In some aspects, large-scale solar power plants deploy plastic bags, mesh bags, balloons, or other unintended closure devices, such as Fig.26 As depicted, a separate device may be required to couple the bag to the connector, such as a cable tie or tape. In addition, large-scale solar power plants also deploy separate dust protection devices, such as Fig. 27 Depicted. It would be advantageous to use a suitable latching device for the solar connector that complies with OSHA requirements and requires a tool to be removed. It would also be advantageous to combine the latching device with a means for coupling the latching device to the solar connector, which may be described as "self-locking". It would also be advantageous to combine a self-locking latching member and a dust protection member to increase the efficiency of installation of the latching device and the dust protection. In addition, a single component may be superior to the current method of using separate components due to less material usage, which may be a more cost-effective solution than the separate components.

[0073] The embodiments of the self-locking dust cap closure described herein combine the self-locking locking member and the dust protection member into a single component. This is advantageous for cable assembly companies and solar construction and installation companies because the single component has less material and lower cost than three separate components. The single component aspect of the self-locking dust cap closure will result in fewer materials and components in a solar power plant or solar cable assembly plant than traditional locking and dust protection devices, which are easier to manage and keep track of during the assembly phase of the solar cable and the construction phase of the solar power plant. This results in cable assemblers and solar construction and installation companies saving time and money by improving efficiency.

[0074] An additional benefit is that the single component aspect of the self-locking dust cap closure will result in fewer shipping boxes than using various components, which are easier to manage and keep track of during the solar cable assembly phase and the construction phase of the solar power plant, which saves time and money for cable assemblers and solar construction and installation companies. In addition, the single component aspect of the device results in fewer parts for factory workers or installers to carry around the solar cable assembly plant or large-scale solar power plant, thereby improving the productivity of the workers or installers because there is less weight to carry and fewer parts to manage. By being made of a single component, the self-locking dust cap closure disclosed herein results in fewer parts to be lost, because small parts such as dust caps may easily fall off and be lost in the dirt, tall grass or snow typically found in large-scale solar power plants. In addition, the single component aspect of the self-locking dust cap closure results in fewer parts to be assembled or installed, which is faster for assemblers or installers than using various components, which saves time and money for solar cable assembly and solar construction and installation companies. Additionally, the single component aspect of the self-locking dust cap closure results in fewer parts to inspect for quality, which saves time and money for cable assemblies and solar construction and installation companies.

[0075] The solar lockouts and dust shields disclosed herein are configured to couple with any solar connector and wire assembly. In large-scale solar power plants, this may result in the need to install tens of thousands of lockouts and dust shields, so solar construction and installation companies are constantly developing methods to reduce the time required to install the lockouts and sun shields found in large-scale solar power plants. The benefits of the self-locking dust cap lockouts described above reduce the time required to install the lockouts and dust shields found in large-scale solar power plants.

[0076] Solar connector self-locking dust cap closures may have a variety of embodiments that are used to lock and prevent dust from entering the solar connector. The embodiments of the self-locking dust cap closures disclosed herein may include: a circular body that may be a solid body to act as a plug, or may be a hollow body to act as a cap; a thin and flexible extension member; a thin and flexible end tail that has a ribbed ratchet feature; and a ratchet locking feature that locks the end tail in place at various locations. In addition, some embodiments of the self-locking dust cap closures have a support body coupled to the cable of the connector. The end tail cannot be removed from the ratchet locking feature without destroying the ratchet locking feature with a tool. In addition, the circular body cannot be removed from the solar connector until the extension member or the end tail is cut off with a tool. In other embodiments of the self-locking dust cap closures disclosed herein, it may include: a circular body that acts as a plug; a support body that has a large through hole to couple and lock with the locking feature of the solar connector; and a side tab that has a small through hole for coupling a safety tag to the device. The device cannot be removed without engaging the locking feature of the solar connector with a specialized custom tool or a disconnect tool for the solar connector. If an untrained installer attempts to forcefully and improperly remove the security tag, the side tabs may break off, providing a visual indication of tampering. All embodiments of the self-locking dust cap latching device disclosed herein can be designed for a variety of solar electrical connectors, such as MC4, H4, SOLARLOK, TE Connectivity.

[0077] All embodiments of the self-locking dust cap closure disclosed herein can be made of non-conductive materials, such as thermoplastic materials or any non-conductive materials. The self-locking dust cap closure should be made of materials that have insulation and anti-electrical properties, which can make the self-locking dust cap closure safe to touch during power-on. All embodiments of the self-locking dust cap closure disclosed herein can be made of materials that meet industry standard UL rated flammability requirements. The self-locking dust cap closure can be made in any color, but is typically made in a bright and safe color for better consistency. For example, the solar closure system can be colored a bright and safe red.

[0078] Figures 1 to 8 1 and 2 depict exemplary aspects of a self-locking dust cap closure 10. The self-locking dust cap closure 10 may be configured for use as a solar connector closure and dust protection device for large-scale solar power plants, combining a closure member and a dust protection member into a single component. The self-locking dust cap closure 10 is configured to couple to solar connectors found across large-scale solar power plants.

[0079] The self-locking dust cap closure 10 includes a circular body 12, a protrusion 14, a protrusion 16, and tabs 18, 20. The circular body 12 includes a through hole 22 that allows access to the interior volume 13. The circular body 12 is configured to act as a dust cap to protect the connector 1 ( Figure 8 The protrusions 28, 30 are arranged on either side of the circular body 12. As described in detail below, when the locking device 10 is arranged on the connector 1 ( Figure 8 ), the protrusions 28 , 30 protect the tabs 2 , 4 of the connector 1 .

[0080] The protrusion 14 is arranged on the circular body 12 opposite the protrusion 16, thereby forming a channel 15 and including through holes 24 and 32. The through hole 24 is configured to allow the tab 2 of the connector 1 to pass into the locking device 10. The flange 23 can be positioned on the inner surface of the protrusion 14 and is configured to interact with the tab 2 once fully inserted into the channel 15. Once the tab 2 passes through the through hole 24 and is arranged in the channel 15 between the protrusion 14 and the circular body 12, the tab 2 engages with the flange 23, thereby preventing the tab 2 from being removed unless the tab 2 is deformed to disengage the flange 23. In this arrangement, the protrusion 14 and the circular body 12 protect the tab 2 from the outside weather.

[0081] In addition, the protrusion 16 forms a channel 17 and includes through holes 26 and 34. The through hole 26 is configured to allow the tab 4 of the connector 1 to pass into the locking device 10. The flange 21 can be positioned on the inner surface of the protrusion 16 and is configured to interact with the tab 4 once fully inserted into the channel 17. Once the tab 4 is positioned through the through hole 26 and enters the channel 17, the tab 4 engages with the flange 21, thereby preventing the tab 4 from being removed unless the tab 4 is deformed to disengage the flange 21. In this arrangement, the protrusion 16 and the circular body 12 protect the tab 4 from the outside weather. Because the protrusions 12, 14 are arranged in combination with the circular body 12, the tabs 2, 4 are partially enclosed in the channels 15 and 17, and some kind of tool may be required to deform the tabs 2, 4 in order to remove the connector 1 from the locking device 10.

[0082] Through holes 32, 34 are disposed on protrusions 14, 16, respectively, and are configured to receive further securing means, such as a safety strap, security tag, or cable tie, to prevent unauthorized removal of latching device 10 from connector 1. Additionally, tabs 18 and 20 may be integral to latching device 10 and configured to provide a surface for pushing or pulling the device during removal. In one aspect, circular body 12, protrusions 14, 16, and tabs 18, 20 are integral to latching device 10. In one aspect, circular body 12, protrusions 14, 16, and tabs 18, 20 may vary in size and length to accommodate a variety of solar connector types.

[0083] In an exemplary aspect, the self-locking dust cap closure device 10 is manufactured as a single piece. The self-locking dust cap closure device 10 can be manufactured by an injection molding process or a 3D printing process. The material made of the closure device 10 can be a flexible and deformable polymer.

[0084] Figures 7 and 8 A self-locking dust cap closure 10 is depicted coupled to a male solar connector 1 having a wire 5. Although one type of solar connector is depicted, other solar connector types may also be used in conjunction with the self-locking dust cap closure 10. To properly position the self-locking dust cap closure 10 onto the solar connector 1, the male adapter 3 is inserted into the circular body 12 and the tabs 2, 4 pass through the through holes 24, 26 and couple with the flanges 21, 23 of the closure 10. The self-locking dust cap closure 10 can then only be removed with a solar connector disconnect tool, which disengages the tabs 2, 4 from the flanges 21, 23. As described above, after the self-locking dust cap closure 10 is installed on the solar connector 1, a security tag may be coupled through the through holes 32, 34.

[0085] The self-locking dust cap closure 10 can be configured to fit around larger or smaller solar connectors depending on the requirements of the deployment application. For example, the circular body can be increased or decreased in diameter or length, or the large through hole can be increased or decreased in size or moved in position on the support body. This is advantageous because a variety of solar connectors can be used depending on the specific requirements of the site.

[0086] Figures 9 to 17 Another aspect of a self-locking dust cap closure 50 is depicted. The self-locking dust cap closure 50 can be configured for use as a solar connector closure and dust protection device for large-scale solar power plants, which combines the closure member and the dust protection member into a single component. The self-locking dust cap closure 50 is configured to be primarily coupled to female solar connectors found across large-scale solar power plants.

[0087] The latching device 50 includes a support body 52 that acts as a cover over the connector. The support body 52 also includes through holes 62, 64 arranged on opposite sides of a circular body 74 that allow a disconnection tool to pass through the support body 52 in order to deform the locking tabs 70, 72. The self-locking dust cap latching device 50 also includes: a circular hollow body 64 that acts as a cap; locking tabs 70 and 72 that couple with the locking holes of the solar connector and lock together; and side tabs 54, 56 that have small through holes 58, 60 for coupling a security tag to the device and providing a surface for pushing or pulling the device during removal. Tabs 66, 68 are also positioned radially outward of the locking tabs 70, 72. When the latching device 50 is arranged on the connector 6, the locking tabs 66, 68 provide additional protection to the connector 6.

[0088] In an exemplary aspect, the circular hollow body 74, the tabs 66, 68, the locking tabs 70, 71, and the side tabs 54, 56 can be integral with the support body 52. ​​The locking tabs 70, 72 each include a flange 71, 73, respectively, to engage with corresponding features ( Fig.17 ) engagement. The locking tabs 70, 72 are also configured to allow the circular hollow body 74 to be inserted over the connection point of the female solar connector 6 and to couple with the locking hole of the female solar connector 6. Thus, the self-locking dust cap latch 50 is locked to the solar connector 6 and cannot be removed without using a solar connector disconnect tool. In an exemplary aspect, the circular hollow body 74, the support member 52, the tabs 66, 68, and the locking tabs 70, 72 can vary in size and length to accommodate various solar connector types.

[0089] In an exemplary embodiment, the self-locking dust cap closure device 50 is manufactured as a single piece. The self-locking dust cap closure device 50 can be manufactured by an injection molding process. The material made of the closure device 50 can be a flexible and deformable polymer.

[0090] Figures 15 to 17 The self-locking dust cap closure 50 is depicted coupled to a female solar connector 6. Although one type of solar connector is depicted, other solar connector types may also be used in conjunction with the self-locking dust cap closure 50. To properly position the self-locking dust cap closure 50 onto the solar connector 6, the circular hollow body 74 is inserted over the connection point of the connector 6, and the locking tabs 70, 72 are introduced and allow the flanges 71, 73 to engage with corresponding features ( Fig.17The self-locking dust cap latch 50 can then only be removed with a solar connector disconnect tool, which disengages the device's locking tabs 70, 72 from the locking holes of the female solar connector. After the self-locking dust cap latch 50 is installed on the solar connector, a security tag can be coupled to the latch 50.

[0091] The self-locking dust cap closure 50 can be configured to fit around larger or smaller solar connectors depending on the requirements of the deployment application. For example, the circular hollow body can be increased or decreased in diameter or length, or the locking tab can be increased or decreased in size or moved in position on the support body. This is advantageous because a variety of solar connectors can be used depending on site specific requirements.

[0092] As mentioned above, a disconnect tool may be used to disengage the latch from the connector. Fig.18 An exemplary embodiment of a disconnect tool 80 is depicted. The disconnect tool 80 may include forks 82, 84 positioned on the distal end of a body 81, and a wrench 86 may be positioned on the proximal end of the body 81 opposite the forks 82, 84. The forks 82, 84 are configured so that the outer angled surfaces of the forks 82, 84 contact a tab of a connector or latching device and deform the tab so that the tab disengages from the flange, thereby releasing the latching device from the connector.

[0093] In use, the user inserts the forks 82, 84 into the connector or the locking device and applies a certain force to remove the locking device from the connector. Fig.19 As depicted, the user can use the disconnect tool 80 to deform the tabs 2, 4 of the connector inwardly toward the circular body 12 by applying a force F1 to deform the tabs 2, 4. This will disengage the tabs 2, 4 from the protrusions 14, 16. With the tabs 2, 4 disengaged, the user can apply a force F2 to slide the latch 10 off the connector 1.

[0094] Similarly, Fig. 20 The latch 50 is depicted secured to the connector 6. The user may use the disconnect tool 80 to deform the tabs 70, 72 of the latch 50 inwardly by applying a force F3 with the disconnect tool 80 to deform the tabs 70, 72. With the tabs 70, 72 disengaged, the user may apply a force F4 to slide the latch 50 off the connector 6.

[0095] Figure 21 to Figure 24 1 and 2. Exemplary aspects of a self-locking dust cap closure 100 are depicted in FIG. The self-locking dust cap closure 100 may be configured for use as a solar connector closure and dust protection device for a large-scale solar power plant, which combines a closure member and a dust protection member into a single component. The self-locking dust cap closure 100 is configured to couple to solar connectors found across large-scale solar power plants.

[0096] The self-locking dust cap closure device 100 includes a circular body 101, an extension body 102, a tail 103, and a ratchet locking body 104. The circular body 101 is a solid cylindrical body that is configured to be arranged in the male side of the connector 110. The circular body 101 includes a length corresponding to the length of the extension body 102, so that when the circular body 101 is inserted into the connector, the circular body 101 will not withdraw from the connector 110 due to the length of the extension body 102 being too short, as explained in more detail below. In some aspects, the circular body 101 can have various lengths and diameters so as to be correctly fixed to connectors of different sizes. In addition, the circular body 101 can be a hollow body with an orifice arranged therein so that the circular body 101 is completely assembled above the connector 110. In an exemplary aspect, the circular body 101, the tail 103, and the ratchet locking body 104 are integral with the extension body 102. In an exemplary aspect, circular body 101 , extension member 102 , and end tail 103 may vary in size and length to accommodate a variety of solar connector types.

[0097] The extension body 102 may be a flexible member that allows the circular body 100 to bend relative to the extension body 102 so that the circular body 101 may be parallel to a portion of the extension body 102 when in the connection position on the connector 110. The ratchet locking body 104 is disposed on the end of the extension body 102. The ratchet locking body 104 extends vertically upward from the extension body 102 and is substantially parallel to the circular body 101 when in the disconnection position. The ratchet locking body 104 is capable of flexing relative to the extension body 102 and allows the locking device 100 to be correctly bent around the connector in the connection position. The ratchet body 104 may include teeth 104a disposed in an opening 104b. The opening 104b is configured to allow the end tail 103 to pass therethrough, and the teeth 104a are configured to interact with a ratchet feature disposed on the end tail 103, which will be described in more detail below.

[0098] The end tail 103 corresponds to the ratchet locking body 104 and extends from the extension body 102. The end tail 103 may include a rib-like ratchet feature 103a. The rib-like ratchet feature 103a is configured to allow the end tail 103 to be inserted into the ratchet locking body 104 only in one direction, thereby allowing the end tail 103 to be locked to the ratchet locking body 104. More specifically, the teeth 104a engage with the rib-like ratchet feature 103a, which prevents the end tail 103 from moving out of the opening 104 unless the teeth 104a are deformed to be released from the rib-like ratchet feature 103a. The locking operation of the ratchet body 104 and the end tail 103 may be similar to the locking design of a cable tie.

[0099] In an exemplary aspect, the self-locking dust cap closure 100 is manufactured as a single piece. The self-locking dust cap closure 100 can be manufactured by an injection molding process or a 3D printing process. However, the closure 100 can be formed of multiple parts that are joined together at the assembly stage.

[0100] Fig.24 The self-locking dust cap closure 100 is depicted flexed and bent around a solar connector 110 and a cable 111. Although one type of solar connector size and cable size is depicted, other solar connector types and cable sizes may also be used in conjunction with the self-locking dust cap closure 100. To properly position the self-locking dust cap closure 100 onto the solar connector, the circular body 101 is inserted into the connector 110 and the extension body 102 is extended through the connector 110. The end tail 103 is wrapped around the cable 111 and locked in place with the ratchet locking body 104. The self-locking dust cap closure 100 can then be removed only when the extension body 120 and / or the end tail 103 are cut to release the circular body 102 from the connector 110.

[0101] As described above, the circular body 101 fits within the opening within the connector 110. Since the end tail 103 is wrapped around the cable 111 and fastened with the ratchet locking body 104, the diameter of the wrapped end tail 103 is smaller than the diameter of the connector 110. Therefore, if the circular body 101 is slid away from the connector 110 in the horizontal direction to remove the circular body 101 from the connector 110, the wrapped end tail 103 will abut against the connector 110 where the cable 111 is joined to the connector 110. This prevents the circular body 101 from moving in the horizontal direction by more than a length equal to the difference between the lengths of the extension body 102 and the connector 110.

[0102] The self-locking dust cap closure 100 can be configured to fit around larger or smaller solar connectors and larger or smaller cables as required for the deployment application. For example, the circular body 101 can be increased or decreased in diameter or length, or the extended body can be increased or decreased in length. This is advantageous because a variety of solar connector and cable sizes can be used according to site specific requirements.

[0103] In one aspect, the circular body of the latching device can be configured as a hollow circular body rather than a solid plug. The hollow circular body can act as a cap that fits around part or all of the solar connector and can be configured to be compatible with both male and female solar connectors. Figure 25 to Figure 27A self-locking dust cap latch 200 is shown. The latch 200 may be similar to the latch 100 described above. Therefore, common features will not be described in detail. The self-locking dust cap latch 200 includes a circular body 201, an extension body 202, a tail 203, and a ratchet locking body 204. The circular body 201 is a hollow cylindrical body having an opening 201a that is configured to be arranged around a connector 210. The ratchet body 204 may include teeth 204a arranged in an opening 204b.

[0104] In another aspect, the circular body of the latch may be a hollow body and disposed within the connector rather than around the connector. Figure 28 to Figure 29 A self-locking dust cap latch 300 is shown. The latch 300 may be similar to the latch 200 described above. Therefore, similar components will not be described in detail. The self-locking dust cap latch 300 includes a circular body 301, an extension body 302, a tail 303, and a ratchet locking body 304. The circular body 301 is a hollow cylindrical body having an opening 301a that is configured to be arranged around an internal pin of a connector 310. The ratchet body 304 may include teeth 304a arranged in an opening 304b.

[0105] In some aspects, the hollow circular body can be increased or decreased in diameter or length to be compatible with various connector types. In addition, multiple extension bodies, support bodies, and ratchet locking features can be added to the device so that the end tail can be locked at various locations along the device, making the device compatible with various connector lengths and sizes, as described in more detail below.

[0106] Figure 30 to Figure 34 Another aspect of a self-locking dust cap latch 400 is depicted. The self-locking dust cap latch 400 can be configured for use as a solar connector latch and dust lock for large-scale solar power plants, combining a latch member and a dust lock member into a single component. The self-locking dust cap latch 400 is configured to couple to solar connectors found across large-scale solar power plants. The self-locking dust cap latch 400 is different in design from the self-locking dust cap latch 100.

[0107] The self-locking dust cap latching device 400 includes a circular body 401 that acts as a plug, a support body 402 having large through holes 403 and 404 to couple and lock together with the locking features of the solar connector, side tabs 405 and 406 that hinder and prevent misaligned engagement with the solar connector and provide a surface for pushing or pulling the device during removal, small through holes 407 and 408 for coupling a security tag to the device, and a protective tab 409 disposed on the outer edges of the through holes 403, 405. In one aspect, the circular body 402, the large through holes 403 and 404, the side tabs 405 and 406, the small through holes 407 and 408, and the tab 409 are integral with the support body 402. The through holes 403 and 404 are configured to allow the circular body 401 to be inserted into the connection point of the male solar connector and to couple with the locking tabs of the male solar connector. Thus, the self-locking dust cap latch 400 is locked to the solar connector and cannot be removed without using a solar connector disconnect tool. In one aspect, the circular body 401, support member 402, large through holes 403 and 404 can vary in size and length to accommodate various solar connector types.

[0108] In an exemplary aspect, the self-locking dust cap closure device 400 is manufactured as a single piece. The self-locking dust cap closure device 400 can be manufactured by an injection molding process or a 3D printing process.

[0109] Fig.34 A self-locking dust cap closure 400 is depicted coupled to a male solar connector 410 having a wire 411. Although one type of solar connector is depicted, other solar connector types may also be used in conjunction with the self-locking dust cap closure 400. To properly position the self-locking dust cap closure 400 onto the solar connector 410, the circular body 401 is inserted into the connector and the large through holes engage and couple with the locking tabs of the male solar connector. The self-locking dust cap closure 400 can then only be removed with a solar connector disconnect tool, which disengages the solar connector locking tabs from the large through holes 403 and 404. After the self-locking dust cap closure 400 is installed on the solar connector 410, a security tag may be coupled through the small through holes 407 and 408 or the side tabs 405 and 406, which security tag may be designed to break off and show a visual sign of tampering if an individual attempts to remove the security tag or the self-locking dust cap closure 400 with force or incorrectly.

[0110] The self-locking dust cap closure 400 can be configured to fit around larger or smaller solar connectors depending on the requirements of the deployment application. For example, the circular body can be increased or decreased in diameter or length, or the large through hole can be increased or decreased in size or moved in position on the support body. This is advantageous because a variety of solar connectors can be used depending on the specific requirements of the site.

[0111] Figure 35 to Figure 39 Another aspect of a self-locking dust cap latch 500 is depicted. The self-locking dust cap latch 500 can be configured for use as a solar connector latch and dust lock for large-scale solar power plants, combining a latch member and a dust lock member into a single component. The self-locking dust cap latch 500 is configured to primarily couple to female solar connectors found across large-scale solar power plants.

[0112] The self-locking dust cap closure device 500 includes: a circular hollow body 501, which acts as a cap; a support body 502, which has locking tabs 503 and 504 to couple with the locking hole of the solar connector and lock together; and side tabs, which have small through-hole holes 505 and 506 for coupling the security tag to the device and providing a surface for pushing or pulling the device during removal. In an exemplary aspect, the circular hollow body 502, the locking tabs 503 and 504, and the side tabs with small through-holes 505 and 506 are integral with the support body 502. The locking tabs 503 and 504 are configured to allow the circular hollow body 501 to be inserted over the connection point of the female solar connector and coupled with the locking hole of the female solar connector, so that the self-locking dust cap closure device 500 is locked to the solar connector and cannot be removed without using a solar connector disconnect tool. In an exemplary aspect, circular hollow body 501 , support member 502 , locking tabs 503 and 504 may vary in size and length to accommodate various solar connector types.

[0113] In an exemplary aspect, the self-locking dust cap closure device 500 is manufactured as a single piece. The self-locking dust cap closure device 500 can be manufactured by an injection molding process.

[0114] Fig.39A self-locking dust cap closure 500 is depicted coupled to a female solar connector 510 having wires 511. Although one type of solar connector is depicted, other solar connector types may also be used in conjunction with the self-locking dust cap closure 500. To properly position the self-locking dust cap closure 500 onto the solar connector 510, the circular hollow body 501 is inserted over the connection point of the connector, and the locking feature engages and couples with the locking hole of the female solar connector 510. The self-locking dust cap closure 500 can then only be removed with a solar connector disconnect tool, which disengages the locking tabs 503 and 504 of the device from the locking holes of the female solar connector. After the self-locking dust cap closure 500 is installed on the solar connector, a security tag may be coupled to the side tabs 505 or 506, or the side tabs 505 and 506 may be designed to break off and show a visual sign of tampering if an individual attempts to remove the security tag or the self-locking dust cap closure 500 with force or incorrectly.

[0115] The self-locking dust cap closure 500 can be configured to fit around larger or smaller solar connectors depending on the requirements of the deployment application. For example, the circular hollow body can be increased or decreased in diameter or length, or the locking tab can be increased or decreased in size or moved in position on the support body. This is advantageous because a variety of solar connectors can be used depending on site specific requirements.

[0116] Figure 40 to Figure 43 Another aspect of a self-locking dust cap latch 900 is depicted. The self-locking dust cap latch 600 is substantially similar to the self-locking dust cap latch 400, and therefore common features are not described in detail herein. It should be understood by those skilled in the art that the above description of the self-locking dust cap latch 400 is also applicable to the additional self-locking dust cap latch 600. The self-locking dust cap latch 600 includes: a cylindrical body 601, which is to be inserted into a connector 610 having a wire 611; a support body 602; a through hole 603; and an extension 606, which couples with and locks together with a locking feature of the solar connector 610. The device 600 differs from the device 400 in that a custom-made special tool is required to remove the device from the solar connector.

[0117] Figure 44 to Figure 45Another aspect of a self-locking dust cap closure 1600 is depicted. The self-locking dust cap closure 1600 is substantially similar to the self-locking dust cap closure 100, and therefore common features are not described in detail herein. It should be understood by those skilled in the art that the above description of the self-locking dust cap closure 100 is also applicable to the additional self-locking dust cap closure 1600. The self-locking dust cap closure 1600 can be configured for use as a solar connector closure and dust protection device for large-scale solar power plants, which combines a closure member and a dust protection member into a single component.

In one aspect, the circular body 1601, the end tails 1603 and 1604, and the ratchet lock bodies 1607 and 1608 are integral with the extension bodies 1602 and 1605. The ribbed ratchet features 1603a and 1604a are configured to allow the end tails 1603 and 1604 to be inserted into the ratchet locking bodies 1606 and 1607 in only one direction, thereby allowing the end tails 1603 and 1604 to lock to the ratchet locking features 1606 and 1607. In an exemplary aspect, the circular body 1601, the extension members 1602 and 1605, and the end tails 1603 and 1604 can vary in size and length to accommodate various solar connector types.

The self-locking dust cap closure 1600 can then be removed only when one of the extension body or the end tail is cut off.

[0122] The self-locking dust cap locking device 1600 can be configured to fit around larger or smaller solar connectors and larger or smaller cables as required by the deployment application. For example, the circular body can be increased or decreased in diameter or length, or the extension body can be increased or decreased in length.

[0128] The self-locking dust cap locking device 1800 can be configured to fit around larger or smaller solar connectors and larger or smaller cables as required for deployment purposes. For example, the circular body can be increased or decreased in diameter or length, or the extended body can be increased or decreased in length. This is advantageous because various solar connector and cable sizes can be used according to specific requirements on site. The circular body member 1801 can also be configured as a hollow circular body, rather than a solid plug. The hollow circular body can act as a cap around part or all of the solar connector assembly, and can be configured to be compatible with both male and female solar connectors. The hollow circular body can be increased or decreased in diameter or length to be compatible with various connector types.

The self-locking dust cap closure 2000 is substantially similar to the self-locking dust cap closure 100, and therefore common features are not described in detail herein. It should be understood by those skilled in the art that the above description of the self-locking dust cap closure 100 is also applicable to the additional self-locking dust cap closure 2000.

[0131] In an exemplary aspect, the self-locking dust cap closure device 2000 is manufactured as a single piece. The self-locking dust cap closure device 2000 can be manufactured by an injection molding process or a 3D printing process.

[0132] Fig.49 Depicted is a self-locking dust cap closure 2000 that flexes, bends, and locks into position around a solar connector and cable. Although depicted is one type of solar connector and cable size, other solar connector types and cable sizes may also be used in conjunction with the self-locking dust cap closure 2000.

The end tail 2005 is then locked in place with the ratchet locking body 2004. The self-locking dust cap closure 2000 can then only be removed when the end tail 2005 is cut. When the end tail 2005 is cut, the notched tag body 2006 provides protection from damage by the cutting device used.

[0134] The self-locking dust cap locking device 2000 can be configured to fit around larger or smaller solar connectors and larger or smaller cables as required for deployment purposes. For example, the circular body can be increased or decreased in diameter or length, or the extension body can be increased or decreased in length. This is advantageous because a variety of solar connector and cable sizes can be used according to specific requirements on site. The circular body member 2001 can also be configured as a hollow circular body, rather than a solid plug. The hollow circular body can act as a cap that fits around part or all of the solar connector, and can be configured to be compatible with both male and female solar connectors.
