Description

Technical Field

[0001] This utility model relates to the field of energy storage device technology, and more specifically, to a socket protection device and an energy storage device. Background Technology

[0002] Currently, balcony photovoltaic (PV) energy storage devices are receiving increasing attention as a core component of home energy storage systems, and their adoption rate is gradually increasing. In home settings, balcony PV energy storage devices can serve as emergency energy storage devices to cope with unexpected situations such as power outages. Furthermore, due to their portable design and large storage capacity, balcony PV energy storage devices can also play an indispensable role in outdoor settings.

[0003] In related technologies, balcony photovoltaic energy storage equipment includes a box or enclosure, which has a wiring port. Users can plug their electrical equipment into the wiring port to allow the balcony photovoltaic energy storage equipment to supply power to the equipment and meet their electricity needs.

[0004] For convenient electricity use, the wiring ports of photovoltaic energy storage devices on balconies are usually exposed, making them susceptible to the entry of rainwater, dust, and other impurities, posing safety hazards and making them difficult to clean. Utility Model Content

[0005] In order to solve or improve the technical problem that rainwater, dust and other impurities can easily enter the wiring port, posing a safety hazard and making it difficult to clean, one objective of this utility model is to provide a socket protection device.

[0006] Another objective of this invention is to provide an energy storage device having the aforementioned socket protection device.

[0007] To achieve the above objectives, the first aspect of this utility model provides a socket protection device for connecting to the wiring port of an energy storage device. The socket protection device includes: at least two connected folding portions, each folding portion having an open wire groove; and a fixing portion disposed at one end of the folding portion, the fixing portion being connected to the wiring port. When the socket protection device is in a compressed state, in any two adjacent folding portions, the folding portion farther from the fixing portion can be located within the folding portion closer to the fixing portion. During the stretching of the folding portion away from the fixing portion, the open wire groove gradually increases in size as the folding portion stretches. During the compression of the folding portion towards the fixing portion, the open wire groove gradually decreases in size as the folding portion compresses.

[0008] In the technical solution defined by this utility model, by placing the socket protection device at the wiring port of the energy storage device, it can largely prevent rainwater, dust and other impurities from entering, which is beneficial to improving safety performance, reducing safety hazards, and also improving the cleanliness of the wiring port.

[0009] In addition, staff can stretch or compress the socket protection device according to actual needs (switching between the stretched and compressed states) to adjust the size of the opening cable tray. This design can largely prevent rainwater, dust and other impurities from entering without delaying wiring and cable routing, thereby improving safety performance and the cleanliness of the wiring port.

[0010] In some technical solutions, the socket protection device may optionally include a support piece disposed at at least one fold, wherein the stiffness of the support piece is greater than that of the fold.

[0011] In this technical solution, by setting a support plate, rigidity support can be provided to the folding parts when at least two connected folding parts are folded, without affecting the flexibility of folding. The folding parts have sufficient rigidity, and under external force, they fold first and then deform, to ensure that the smaller folding part can be smoothly inserted into the larger folding part.

[0012] In some technical solutions, optionally, the folded part has a first dimension in the first direction, and the support piece has a second dimension in the first direction, the second dimension being 0.2 to 0.4 times the first dimension.

[0013] In this technical solution, by limiting the dimensional ratio between the support plate and the folding part in the first direction, firstly, the size of the support plate is avoided from being too large, thereby avoiding material waste and reducing production costs; secondly, the size of the support plate is avoided from being too small, so as to ensure that the folding part folds first under the action of external force, and then deforms.

[0014] In some technical solutions, optionally, the folding part is provided with a first cavity, a support piece is disposed in the first cavity, and the outer wall of the support piece is fitted with the cavity wall of the first cavity.

[0015] In this technical solution, the first cavity provides installation space for the support piece, allowing the outer wall of the support piece to fit snugly against the cavity wall of the first cavity. The support piece, acting as a reinforcing structure, is embedded within the first cavity of the folded portion, which improves the rigidity of the folded portion and largely prevents the support piece from falling off.

[0016] In some technical solutions, the socket protection device may optionally include: a first support plate disposed on the fixing part, wherein the rigidity of the first support plate is greater than the rigidity of the fixing part.

[0017] In this technical solution, the addition of a first support plate improves the rigidity of the fixing part, i.e., its resistance to deformation. This increased resistance enhances the connection strength between the fixing part and the wiring port, significantly reducing the risk of deformation and instability when the user stretches or compresses the socket protection device.

[0018] In some technical solutions, optionally, the fixing part is provided with a second cavity, the first support plate is disposed in the second cavity, and the outer wall of the first support plate is fitted with the cavity wall of the second cavity.

[0019] In this technical solution, the second cavity provides installation space for the first support plate, allowing the outer wall of the first support plate to fit snugly against the cavity wall of the second cavity. The first support plate, as a reinforcing structure, is embedded within the second cavity of the fixing part, which improves the rigidity of the fixing part and ensures the fitting accuracy between the fixing part and the housing, preventing protective failure due to loosening of the fixing part.

[0020] In some technical solutions, optionally, the first support plate is provided with a flange structure, at least a part of which is connected to the folding part, and the stiffness of the flange structure is greater than that of the folding part.

[0021] In this technical solution, the flange structure is mainly used to strengthen the rigidity of the connection between the folding part and the fixed part, so that the folding part has a sufficiently large resistance to deformation near the fixed part, effectively preventing the folding part from collapsing near the fixed part under external force.

[0022] In some technical solutions, optionally, the folded part is provided with a third cavity, the flange structure is provided in the third cavity, and the outer wall of the flange structure is fitted with the cavity wall of the third cavity.

[0023] In this technical solution, the flange structure, as a reinforcing structure, is embedded in the third cavity of the folding part. This ensures the connection strength between the flange structure and the folding part while improving the folding part's resistance to deformation near the fixing part, effectively preventing the folding part from collapsing near the fixing part.

[0024] In some technical solutions, the socket protection device may optionally include a protective cover located at the end of the folded portion away from the fixed portion.

[0025] In this technical solution, the user can press or pull the socket protection device with the protective cover to switch the socket protection device between an extended state and a compressed state, thereby adjusting the size of the opening cable tray. The operation is simple, convenient and quick.

[0026] The second aspect of this utility model provides an energy storage device, including: a housing with a wiring port on the housing; and a socket protection device as described in any of the above technical solutions, which is located at the wiring port and has a fixing part connected to the outer wall of the housing.

[0027] Since the energy storage device includes any of the socket protection devices mentioned in the first aspect above, it has the beneficial effects of any of the above technical solutions, which will not be elaborated here.

[0028] Additional aspects and advantages of the present invention will become apparent in the following description or may be learned by practice of the present invention. Attached Figure Description

Detailed Implementation

[0044] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0045] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, embodiments of the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0046] The following reference Figures 1 to 13 This invention describes a socket protection device and an energy storage device provided according to some embodiments of the present invention.

[0047] In one embodiment of the present invention, the socket protection device 100 is used to connect to the wiring port 211 of the energy storage device 200.

[0048] Optionally, the energy storage device 200 is a balcony photovoltaic energy storage device. It should be noted that the wiring port 211 of the energy storage device 200 is a socket, and this socket is an AC output socket. Users can plug their electrical equipment into the AC output socket to allow the energy storage device 200 to supply power to the electrical equipment and meet their electricity needs.

[0049] The socket protection device 100 of this utility model is used to protect the AC output socket of a photovoltaic energy storage device on a balcony. The AC output socket can output AC power to supply AC loads.

[0050] In some scenarios, such as power outages, the balcony photovoltaic energy storage device (energy storage device 200) can supply power to important loads (such as refrigerators) through this AC output socket. In other scenarios, users can also take the balcony photovoltaic energy storage device outdoors for use. Through this AC output socket, users can use some electrical appliances outdoors, such as kettles and air fryers.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the socket protection device 100 includes at least two connected folding portions 110 and fixing portions 120. The folding portions 110 are provided with open wire channels 180. The open wire channels 180 are for passing wire harnesses. The wire harnesses are used to connect to the wiring port 211 (i.e., AC output socket) of the energy storage device 200.

[0052] It should be noted that during the stretching of at least two connected folds 110 along the first direction a, the overall length of the socket protection device 100 increases and the open wire groove 180 gradually increases; during the compression of at least two connected folds 110 along the first direction a, the overall length of the socket protection device 100 decreases and the open wire groove 180 gradually decreases.

[0053] Optionally, the first direction 'a' is the length direction of the socket protection device 100 (e.g., ...). Figure 1 , Figure 2 , Figure 3 and Figure 6 (As shown).

[0054] The fixing part 120 is located at one end of the folding part 110 and is connected to the wiring port 211.

[0055] Optionally, such as Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the energy storage device 200 includes a housing 210, and a wiring port 211 is provided on the housing 210. The fixing part 120 is detachably connected to the housing 210. When the fixing part 120 is connected to the housing 210, the socket protection device 100 is fixed at the position of the wiring port 211.

[0056] The fixing part 120 is detachably connected to the housing 210. This design makes it convenient for staff to disassemble and install the socket protection device 100, which is beneficial for maintenance or replacement.

[0057] In one specific embodiment, the fixing part 120 and the housing 210 are detachably connected by bolts, pins or other types of connectors, which is convenient, quick and easy to operate.

[0058] The socket protection device 100 has an extended state (e.g.) Figure 1 , Figure 2 and Figure 3 (as shown) and compression state (as shown) Figure 4 , Figure 5 and Figure 6 (As shown). The socket protection device 100 can switch from an extended state to a compressed state, so that the open wire groove 180 gradually decreases; the socket protection device 100 can switch from a compressed state to an extended state, so that the open wire groove 180 gradually increases.

[0059] When the socket protection device 100 is in the extended state, at least two folding portions 110 and a fixing portion 120 are sequentially arranged in the first direction a. Furthermore, among the at least two folding portions 110, the size of the folding portion 110 closer to the fixing portion 120 is larger than the size of the folding portion 110 farther from the fixing portion 120.

[0060] When the socket protection device 100 is in a compressed state, in any two adjacent folds 110, the fold 110 furthest from the fixing part 120 can be located within the fold 110 closest to the fixing part 120.

[0061] It should be noted that when the cross-sectional shape of the folded part 110 is circular, the "dimension of the folded part 110" can be understood as the "radius or diameter of the folded part 110". When the cross-sectional shape of the folded part 110 is square, the "dimension of the folded part 110" can be understood as the "side length of the folded part 110".

[0062] In one specific embodiment, the folding portion 110 has a square cross-sectional shape. The square-section folding portion 110 includes four side walls and four corner structures. Two adjacent side walls are connected by a corner structure, which is a rounded transition surface. In other words, the corners of the folding portion 110 have rounded transition surfaces. This design helps reduce wear between the socket protection device 100 and other components, extending its service life.

[0063] Normally, in any two adjacent folds 110, the size (here referring to the side length) of the fold 110 farther from the fixing part 120 is smaller than the size of the fold 110 closer to the fixing part 120.

[0064] In one specific embodiment, the folded portion 110 has a circular cross-sectional shape. This structural form of the folded portion 110 is easy to extend and retract, and easy to manufacture.

[0065] Normally, in any two adjacent folds 110, the size (here referring to radius or diameter) of the fold 110 farther from the fixing part 120 is smaller than the size of the fold 110 closer to the fixing part 120.

[0066] During the stretching of the folded portion 110 away from the fixed portion 120, the open groove 180 gradually increases as the folded portion 110 stretches; during the compression of the folded portion 110 towards the fixed portion 120, the open groove 180 gradually decreases as the folded portion 110 is compressed.

[0067] It should be emphasized that the number of folding parts 110 is at least two, that is, there can be two or more folding parts 110, and the number of folding parts 110 can be flexibly set according to actual needs.

[0068] In the technical solution defined by this utility model, by placing the socket protection device 100 at the wiring port 211 of the energy storage device 200, it can largely prevent rainwater, dust and other impurities from entering, which is beneficial to improving safety performance, reducing safety hazards, and also improving the cleanliness of the wiring port 211.

[0069] In addition, staff can stretch or compress the socket protection device 100 according to actual needs (switching between the stretched and compressed states) to adjust the size of the open wire groove 180. This design can largely prevent rainwater, dust and other impurities from entering without delaying wiring and cable routing, thereby improving safety performance and the cleanliness of the wiring port 211.

[0070] It should be emphasized that the socket protection device 100 of this utility model can be adapted to various types of wiring ports 211 (i.e., various types of sockets), has high versatility, and also has multiple functions such as waterproofing, rain protection, and dust protection.

[0071] In some embodiments, optionally, such as Figure 2 , Figure 3 and Figure 8 As shown, the socket protection device 100 also includes a support piece 130. The support piece 130 is disposed on at least one fold portion 110, and the rigidity of the support piece 130 is greater than the rigidity of the fold portion 110.

[0072] Stiffness refers to an object's ability to resist deformation when subjected to external forces. Objects with high stiffness are less prone to deformation under stress and possess higher hardness and strength.

[0073] The support plate 130 serves as a reinforcing structure and can be installed in the folding section 110 either embedded or fitted. The support plate 130 does not completely cover the folding section 110, but is located in key stress areas of the folding section 110 (such as near the folding joint or in areas where the application is concentrated).

[0074] Optionally, a support piece 130 is disposed around the folded portion 110, and the shape of the support piece 130 is adapted to the shape of the folded portion 110. Furthermore, the position of the support piece 130 avoids the open wire groove 180 to ensure that the support piece 130 does not interfere with the passage of the wire harness.

[0075] By providing support plates 130, rigidity support can be provided to the folding portions 110 when at least two connected folding portions 110 are folded, without affecting the flexibility of folding. The folding portions 110 have sufficient rigidity to fold first and then deform under external force, ensuring that the smaller folding portion 110 can smoothly extend into the larger folding portion 110.

[0076] In one specific embodiment, there are three folded portions 110, and the dimensions of the three folded portions 110 decrease sequentially in the direction away from the fixing portion 120. The three folded portions 110 are designated as a first folded portion, a second folded portion, and a third folded portion. One end of the first folded portion is connected to the fixing portion 120, one end of the second folded portion is connected to the other end of the first folded portion, and one end of the third folded portion is connected to the other end of the second folded portion. The dimension of the first folded portion is larger than the dimension of the second folded portion, and the dimension of the second folded portion is larger than the dimension of the third folded portion.

[0077] A support piece 130 is provided on the second folding portion to ensure that the second folding portion has sufficient rigidity. During the compression of the folding portion 110 in the direction close to the fixing portion 120, the third folding portion can be housed inside the second folding portion, and because the second folding portion has sufficient rigidity, during the continued compression, the second folding portion and the third folding portion housed inside the second folding portion can be housed together inside the first folding portion.

[0078] In one specific embodiment, the support piece 130 and the folding part 110 are fixedly connected by integral injection molding to ensure the connection strength between the support piece 130 and the folding part 110, which can largely prevent the support piece 130 from falling off.

[0079] In one specific embodiment, the support sheet 130 is a stainless steel sheet, that is, the support sheet 130 is made of stainless steel (SUS, Stainless Steel).

[0080] Optionally, the thickness of the support sheet 130 is 0.2 mm to 0.5 mm.

[0081] By limiting the thickness range, firstly, it avoids the support piece 130 being too thick, which would cause the folding part 110 to have excessive rigidity, and also avoids material waste, which is conducive to reducing production costs; secondly, it avoids the support piece 130 being too thin, which would cause the folding part 110 to have excessive rigidity, so as to ensure that the folding part 110 folds first under the action of external force, and then deforms.

[0082] In one specific embodiment, the thickness of the support sheet 130 is 0.2 mm.

[0083] In one specific embodiment, the thickness of the support sheet 130 is 0.3 mm.

[0084] In one specific embodiment, the thickness of the support sheet 130 is 0.4 mm.

[0085] In one specific embodiment, the thickness of the support sheet 130 is 0.5 mm.

[0086] In some embodiments, optionally, such as Figure 2 As shown, the folding part 110 has a first dimension H1 in the first direction a, and the support piece 130 has a second dimension H2 in the first direction a, which is 0.2 to 0.4 times the first dimension H1.

[0087] By limiting the dimensional ratio between the support plate 130 and the folding part 110 in the first direction a, firstly, the size of the support plate 130 is avoided from being too large, thereby avoiding material waste and reducing production costs; secondly, the size of the support plate 130 is avoided from being too small, so as to ensure that the folding part 110 folds first under the action of external force, and then deforms.

[0088] It should be noted that the support plate 130 does not completely cover the folding part 110, but is set in the key stress areas of the folding part 110 (such as the position near the folding joint or the area where the application is concentrated).

[0089] In one specific embodiment, the second dimension H2 is 0.2 times the first dimension H1.

[0090] In one specific embodiment, the second dimension H2 is 0.3 times the first dimension H1.

[0091] In one specific embodiment, the second dimension H2 is 0.4 times the first dimension H1.

[0092] In some embodiments, optionally, such as Figure 2 and Figure 3The folding part 110 is provided with a first cavity 111, and the support piece 130 is disposed in the first cavity 111. The outer wall of the support piece 130 is in contact with the cavity wall of the first cavity 111.

[0093] Optionally, the support piece 130 is snapped into the first cavity 111 so that the support piece 130 is relatively fixed to the folding part 110, and the support piece 130 is not easily dislodged from the folding part 110 when the user stretches or compresses the socket protection device 100. The support piece 130, as a reinforcing structure, is installed in the first cavity 111 of the folding part 110 in an embedded manner.

[0094] Optionally, the support piece 130 and the folding part 110 are fixedly connected by integral injection molding to ensure the connection strength between the support piece 130 and the folding part 110, which can largely prevent the support piece 130 from falling off.

[0095] The first cavity 111 provides installation space for the support piece 130, so that the outer wall of the support piece 130 fits against the cavity wall of the first cavity 111. The support piece 130, as a reinforcing structure, is embedded in the first cavity 111 of the folding part 110, which helps to improve the rigidity of the folding part 110 and can largely prevent the support piece 130 from falling off.

[0096] In some embodiments, optionally, such as Figure 2 , Figure 3 and Figure 7 As shown, the socket protection device 100 also includes a first support plate 141. The first support plate 141 is disposed on the fixing part 120, and the rigidity of the first support plate 141 is greater than the rigidity of the fixing part 120.

[0097] Stiffness refers to an object's ability to resist deformation when subjected to external forces. Objects with high stiffness are less prone to deformation under stress and possess higher hardness and strength.

[0098] The first support plate 141 serves as a reinforcing structure and can be installed in the fixing part 120 in an embedded or fitted manner. The first support plate 141 may partially cover the fixing part 120, or it may completely cover the fixing part 120, depending on actual needs.

[0099] By setting the first support plate 141, the rigidity of the fixing part 120 is improved, that is, the deformation resistance of the fixing part 120 is enhanced. By improving the deformation resistance of the fixing part 120, the connection strength between the fixing part 120 and the wiring port 211 is improved, which can largely prevent the fixing part 120 from deforming and causing the connection to be unreliable when the user stretches or compresses the socket protection device 100.

[0100] It should be emphasized that by placing the first support plate 141 on the fixing part 120, the deformation of the fixing part 120 under installation load (such as screw tightening force) or external impact force can be effectively suppressed, ensuring the fitting accuracy between the fixing part 120 and the housing 210, and avoiding the failure of protection due to the loosening of the fixing part 120.

[0101] In one specific embodiment, the first support plate 141 and the fixing part 120 are fixedly connected by integral injection molding to ensure the connection strength between the first support plate 141 and the fixing part 120, which can largely prevent the first support plate 141 from falling off.

[0102] In one specific embodiment, the first support plate 141 is an aluminum plate, that is, the material of the first support plate 141 is aluminum.

[0103] Optionally, the thickness of the first support plate 141 is 1 mm to 2 mm.

[0104] By limiting the thickness range, firstly, the thickness of the first support plate 141 is avoided from being too large, thus avoiding material waste and reducing production costs; secondly, the thickness of the first support plate 141 is avoided from being too small, ensuring that the fixing part 120 has sufficient resistance to deformation (rigidity).

[0105] In one specific embodiment, the thickness of the first support plate 141 is 1 mm.

[0106] In one specific embodiment, the thickness of the first support plate 141 is 1.2 mm.

[0107] In one specific embodiment, the thickness of the first support plate 141 is 1.5 mm.

[0108] In one specific embodiment, the thickness of the first support plate 141 is 1.8 mm.

[0109] In one specific embodiment, the thickness of the first support plate 141 is 2 mm.

[0110] In some embodiments, optionally, such as Figure 2 and Figure 3 As shown, the fixing part 120 is provided with a second cavity 121, and the first support plate 141 is disposed in the second cavity 121, and the outer wall of the first support plate 141 is in contact with the cavity wall of the second cavity 121.

[0111] Optionally, the first support plate 141 is fitted into the second cavity 121 to fix the first support plate 141 relative to the fixing part 120, ensuring that the fixing part 120 has a sufficiently large resistance to deformation. The first support plate 141, as a reinforcing structure, is installed in the second cavity 121 of the fixing part 120 in an embedded manner.

[0112] Optionally, the first support plate 141 and the fixing part 120 are fixedly connected by integral injection molding to ensure the connection strength between the first support plate 141 and the fixing part 120, which can largely prevent the first support plate 141 from falling off.

[0113] The second cavity 121 provides installation space for the first support plate 141, allowing the outer wall of the first support plate 141 to fit against the cavity wall of the second cavity 121. The first support plate 141, as a reinforcing structure, is embedded within the second cavity 121 of the fixing part 120, which improves the rigidity of the fixing part 120 and ensures the fitting accuracy between the fixing part 120 and the housing 210, preventing protective failure due to loosening of the fixing part 120.

[0114] In some embodiments, optionally, such as Figure 2 , Figure 3 and Figure 7 As shown, the first support plate 141 is provided with a flange structure 142, at least a part of the flange structure 142 is connected to the folding part 110, and the stiffness of the flange structure 142 is greater than the stiffness of the folding part 110.

[0115] The flange structure 142 serves as a reinforcing structure and is embedded in the folding part 110. The flange structure 142 is mainly used to strengthen the rigidity of the connection between the folding part 110 and the fixing part 120, so that the folding part 110 has sufficient resistance to deformation near the fixing part 120, effectively preventing the folding part 110 from collapsing near the fixing part 120 under external force.

[0116] Optionally, the number of flange structures 142 is at least one, that is, there can be one, two or more flange structures 142. Taking into account the rigidity of the connection position between the folding part 110 and the fixing part 120, the ease of processing, cost and other factors, the number of flange structures 142 can be flexibly set according to actual needs.

[0117] In one specific embodiment, the first support plate 141 and the flange structure 142 are an integral structure. Compared with post-processing methods (such as assembly connection or welding), it has better mechanical properties and higher connection strength, which helps to reduce the number of parts and improve assembly efficiency.

[0118] In some embodiments, optionally, such as Figure 2and Figure 3 As shown, the folding part 110 is provided with a third cavity 112, and the flange structure 142 is provided in the third cavity 112, and the outer wall of the flange structure 142 is fitted with the cavity wall of the third cavity 112.

[0119] Optionally, the flange structure 142 is fitted into the third cavity 112 so that the flange structure 142 is fixed relative to the folding part 110, ensuring that the folding part 110 has a sufficiently large resistance to deformation at the position near the fixing part 120.

[0120] Optionally, the flange structure 142 and the folded part 110 are fixedly connected by integral injection molding to ensure the connection strength between the flange structure 142 and the folded part 110.

[0121] The third cavity 112 provides installation space for the flange structure 142, allowing the outer wall of the flange structure 142 to fit against the cavity wall of the third cavity 112. The flange structure 142, as a reinforcing structure, is embedded within the third cavity 112 of the folding portion 110. This ensures the connection strength between the flange structure 142 and the folding portion 110 while simultaneously increasing the deformation resistance of the folding portion 110 near the fixing portion 120, effectively preventing the folding portion 110 from collapsing near the fixing portion 120.

[0122] In some embodiments, optionally, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 and Figure 6 As shown, the socket protection device 100 also includes a protective cover 150. The protective cover 150 is located at the end of the folding portion 110 away from the fixing portion 120.

[0123] The user presses or pulls the socket protection device 100 by the protective cover 150, meaning the protective cover 150 is usually subjected to pressing or pulling force. When the user presses the protective cover 150, the socket protection device 100 switches from an extended state to a compressed state; when the user pulls the protective cover 150, the socket protection device 100 switches from a compressed state to an extended state.

[0124] Users can press or pull the socket protection device 100 by the protective cover 150 to switch the socket protection device 100 between the extended and compressed states, thereby adjusting the size of the opening wire groove 180. The operation is simple, convenient and quick.

[0125] In some embodiments, optionally, such as Figure 3 and Figure 9As shown, the socket protection device 100 also includes a second support plate 160. The second support plate 160 is disposed on the protective cover 150, and the rigidity of the second support plate 160 is greater than the rigidity of the protective cover 150.

[0126] The second support plate 160 serves as a reinforcing structure and can be installed on the protective cover 150 in an embedded or fitted manner. The second support plate 160 may partially cover the protective cover 150, or it may completely cover the protective cover 150, depending on actual needs.

[0127] By setting the second support plate 160, the rigidity of the protective cover 150 is improved, that is, the deformation resistance of the protective cover 150, which makes it convenient to press or pull the socket protection device 100 through the protective cover 150.

[0128] In one specific embodiment, the second support plate 160 and the protective cover 150 are fixedly connected by integral injection molding to ensure the connection strength between the second support plate 160 and the protective cover 150, which can largely prevent the second support plate 160 from falling off.

[0129] In one specific embodiment, the second support plate 160 is an aluminum alloy plate, that is, the material of the second support plate 160 is aluminum alloy.

[0130] Optionally, the thickness of the second support plate 160 is 1 mm to 2 mm.

[0131] By limiting the thickness range, firstly, the thickness of the second support plate 160 is avoided from being too large, thus avoiding material waste and reducing production costs; secondly, the thickness of the second support plate 160 is avoided from being too small, ensuring that the protective cover 150 has sufficient resistance to deformation (rigidity).

[0132] In one specific embodiment, the thickness of the second support plate 160 is 1 mm.

[0133] In one specific embodiment, the thickness of the second support plate 160 is 1.2 mm.

[0134] In one specific embodiment, the thickness of the second support plate 160 is 1.5 mm.

[0135] In one specific embodiment, the thickness of the second support plate 160 is 1.8 mm.

[0136] In one specific embodiment, the thickness of the second support plate 160 is 2 mm.

[0137] In some embodiments, the folding portion 110, the protective cover 150, and the fixing portion 120 are optionally integrated into a single structure, meaning the socket protection device 100 is integrally injection molded. This design ensures sufficient connection strength between the components, reduces the number of parts, thereby reducing the number of assembly steps and improving assembly efficiency.

[0138] Optionally, the socket protection device 100 is made of a material that is elastic, heat-resistant, and light-resistant, such as TPE (Thermoplastic Elastomer), PU (Polyurethane), EPDM (Ethylene-Propylene-Diene Monomer Rubber), etc.

[0139] In a specific embodiment, such as Figure 9 As shown, the second support plate 160 is provided with a fourth connecting hole 161. Since the second support plate 160 and the protective cover 150 are integrally injection molded, at least a part of the protective cover 150 is provided in the fourth connecting hole 161, which is beneficial to increase the contact area between the protective cover 150 and the second support plate 160, thereby improving the connection strength between the protective cover 150 and the second support plate 160.

[0140] In some embodiments, optionally, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the socket protection device 100 also includes at least one first connecting portion 170. A folding portion 110 is connected to the first connecting portion 170. Any two adjacent folding portions 110 are connected via the first connecting portion 170. When the socket protection device 100 is in a compressed state,

[0141] In any two adjacent folds 110, the fold 110 further away from the fixing part 120 (the smaller fold 110) is housed in the first connecting part 170, and the first connecting part 170 and the fold 110 housed in the first connecting part 170 are together housed in the fold 110 closer to the fixing part 120 (the larger fold 110).

[0142] By cooperating with the first connecting part 170, the socket protection device 100 can be switched between an extended state and a compressed state, thereby adjusting the size of the opening wire groove 180.
