[0038] The present application provides a row plug 10, please refer to Figures 1 to 3 , the row plug 10 includes a functional module 1, a power line assembly 2 and a shell body 3. The electrical equipment takes electricity through the functional module 1. The power line assembly 2 includes a plug 21 and an electrical connection line 22, and the power line assembly 2 is electrically connected with the functional module 1. The shell body 3 has a first accommodating cavity 31 in the inside, the functional module 1 is arranged in the first accommodating cavity 31, and at least part of the power line assembly 2 can extend outside the shell body 3; the shell body 3 is provided with an accommodating groove 32 and a plug interface 33 which are in communication with the outside of the shell body 3, the side wall of the accommodating groove 32 is provided with a fastening protrusion 34, and the plug interface 33 is matched with the pin of the plug 21. Among them, the accommodating groove 32 can accommodate the electrical connection line 22, and the fastening protrusion 34 can be in interference fit with the electrical connection line 22, and the plug interface 33 can accommodate at least part of the pin of the plug 21.
[0039] The row plug 10 is also called power socket, socket, which is a kind of electrical device connecting multiple electrical equipment, which can provide power access point for multiple devices at the same time, and is convenient for users to use multiple electrical equipment.
[0040] The functional module 1 is responsible for distributing and controlling current in the row plug 10, and can have some special functions, such as overload protection, lightning protection, USB charging, etc., and the electrical equipment obtains the processed and distributed electrical energy through it.
[0041] The power line assembly 2 is used to connect the row plug 10 to the external power supply. The power line assembly 2 is composed of a plug 21 and an electrical connection line 22, mainly plays a role in transmitting electrical energy, introduces the electrical energy of the external power supply into the row plug 10, and transmits it to the functional module 1.
[0042] The plug 21 is located at one end of the power cord assembly 2, used for plugging into an external power socket, and its shape, pin number, specifications, etc. are different according to the electrical standards of different countries and regions. Through physical connection and electrical contact with the external socket, the input of electrical energy is realized.
[0043] Exemplarily, the plug 21 can be a two-pin plug 21 or a three-pin plug 21 of the national standard plug 21, or a U.S. standard plug 21, a European standard plug 21, or a British standard plug 21, etc. The specific determination is based on the needs.
[0044] The electric connecting wire 22 is a wire connecting the plug 21 and the internal functional module 1 of the power strip 10, usually wrapped with an insulating outer skin and a conductive metal core, responsible for stable transmission of electrical energy between the plug 21 and the functional module 1. The insulating outer skin can prevent electric shock and avoid current leakage.
[0045] The specific length of the electric connecting wire 22 is not limited here. Exemplarily, the length of the electric connecting wire 22 is 55mm to 65mm. Within this range, the electric connecting wire 22 can have a smaller storage volume under the premise of having a certain use range of the power strip.
[0046] The shell body 3 is the outer shell of the power strip 10, which protects the internal functional module 1, power cord assembly 2, etc. and provides structural support for the installation and fixation of these components, ensuring the mechanical strength and stability of the power strip 10 as a whole.
[0047] The material of the shell body 3 is not limited here. Exemplarily, the shell body 3 can be made of high-strength, flame-retardant engineering plastic, which can effectively prevent damage to internal components by external forces and delay the spread of fire in the event of a fire.
[0048] In some embodiments, the surface of the shell body 3 can be designed with anti-slip texture to facilitate the user to hold and plug the plug 21.
[0049] The first accommodating cavity 31 is a space area specially designed for accommodating the functional module 1 inside the shell body 3. The first accommodating cavity 31 provides a relatively closed and safe installation environment for the functional module 1, protecting it from external physical damage and dust, water vapor, etc.
[0050] The accommodating groove 32 is a groove-shaped structure on the shell body 3 that communicates with the outside, mainly used for storing the electric connecting wire 22. When the electric connecting wire 22 is not in use, it can be neatly placed in the accommodating groove 32, playing a role of arrangement and storage, making the power strip 10 more regular after storage, and reducing the entanglement and disorder of the electric connecting wire 22.
[0051] Exemplarily, some separation structures can be provided inside the accommodating groove 32 to separate and store electric connecting wires 22 of different specifications or purposes, avoiding mutual entanglement.
[0052] The plug interface 33 is an opening on the shell body 3 matched with the plug 21 pin, used for inserting the plug 21 when storing, so that the plug 21 pin can be tightly matched with the plug interface 33, and the plug 21 can be fixed when storing.
[0053] Exemplarily, a protective sleeve can be arranged around the plug interface 33 to prevent foreign matters from entering the plug interface 33 and affecting the electrical connection.
[0054] It should be noted that the shape of the plug interface 33 is matched with the plug 21 pin, and the plug interface 33 is opened according to the specific type of the plug 21.
[0055] The fastening protrusion 34 is a protruding structure on the side wall of the accommodating groove 32, which is used to be in interference fit with the electrical connection line 22. When the electrical connection line 22 is placed in the accommodating groove 32, the fastening protrusion 34 can generate a certain pressure on the electrical connection line 22, so that the electrical connection line 22 can be kept stable in the accommodating groove 32 and is not easy to shake or fall off.
[0056] The power strip 10 provided by the embodiment of the present application realizes the function of supplying power to the electrical equipment by arranging the functional module 1. The first accommodating cavity 31 arranged in the shell body 3 creates a relatively closed and safe installation environment for the functional module 1, which is conducive to enhancing the protection of the functional module 1. In addition, by arranging the accommodating groove 32 and the plug interface 33 on the shell body 3, the electrical connection line 22 can be placed in the accommodating groove 32 and the plug 21 can be inserted into the plug interface 33 to be fixed when the power strip 10 is stored. The interference fit between the fastening protrusion 34 and the electrical connection line 22 further improves the tightness of the cooperation between the electrical connection line 22 and the accommodating groove 32. Placing the power cord assembly 2 in the dedicated accommodating area, thus, is conducive to improving the convenience and aesthetics of the storage of the power strip 10 and reducing the damage risk caused by the winding of the electrical connection line 22.
[0057] In some embodiments, referring to Figures 1 to 3 , the shell body 3 includes a first sub-shell 3a and a second sub-shell 3b which are detachably arranged along a first direction, and the first sub-shell 3a and the second sub-shell 3b define the first accommodating cavity 31; the accommodating groove 32 is arranged in the first sub-shell 3a.
[0058] The first sub-shell 3a is a part of the shell body 3, and cooperates with the second sub-shell 3b to constitute a space for accommodating the internal components of the power strip 10. In the embodiment, it is a bearing part of the accommodating groove 32, and plays a supporting and protecting role for the accommodating groove 32.
[0059] The second sub-shell 3b is corresponding to the first sub-shell 3a, and is assembled along the first direction to cooperatively define the first accommodating cavity 31 for accommodating the important internal components such as the functional module 1 of the power strip 10.
[0060] The connection manner of the first sub-shell 3a and the second sub-shell 3b is not limited here, for example, a buckle and a slot matched with each other can be respectively arranged at the edges of the first sub-shell 3a and the second sub-shell 3b. The buckle can be designed as a flexible structure, and when assembling, the buckle is pressed to be clamped into the slot to realize fixation. In order to increase the stability of the connection, buckles can be arranged at multiple places on the edge, uniformly distributed, to ensure that the entire edge is connected tightly. For example, a large main buckle is arranged at every certain distance, and some small auxiliary buckles are interspersed in between, which can ensure the connection strength and facilitate disassembly.
[0061] The shell body 3 is composed of the first sub-shell 3a and the second sub-shell 3b which are detachably connected along the first direction, and the two combined form the first accommodating cavity 31 for accommodating the core function module 1 of the power strip 10. The accommodating groove 32 is arranged on the first sub-shell 3a, and this layout makes the storage area of the electric connection line 22 associated with the assembly structure of the shell body 3, facilitating the processing of the accommodating groove 32 and the electric connection line 22 during assembly and maintenance.
[0062] The first sub-shell 3a and the second sub-shell 3b are detachably arranged, so that the components of the power strip 10 can be machined and manufactured respectively during the production process, and then assembled. In this way, the production efficiency can be improved and the production cost can be reduced. For example, the first sub-shell 3a and the second sub-shell 3b can be machined at different workstations simultaneously on the production line, and finally quickly assembled. At the same time, for some complex internal structure, the detachable design facilitates the installation of the function module 1 and other components on one of the sub-shells first, and then the assembly with the other sub-shell, improving the convenience and accuracy of assembly.
[0063] In some embodiments, referring to Figure 3 The function module 1 includes the circuit board 11, and the circuit board 11 and the side wall of the first accommodating cavity 31 define the first sub-cavity 311 and the second sub-cavity 312 distributed along the first direction, and the electric connection line 22 is electrically connected with the circuit board 11 in the first sub-cavity 311.
[0064] The specific direction of the first direction is not limited here and can be any direction. For convenience of description, the first direction here is the direction shown in the drawings.
[0065] The circuit board 11, also known as a printed circuit board 11 (PCB), is an important electronic component and is the support body of electronic components and the carrier of electrical connection of electronic components. In the function module 1 of the power strip 10, the circuit board 11 plays a role in connecting various electronic components and realizing circuit layout and signal transmission, so that different circuit functions can be realized.
[0066] The first sub-cavity 311 is a space region jointly defined by the circuit board 11 and the side wall of the first accommodating cavity 31 in the first direction. The first sub-cavity 311 is mainly used to place components that are electrically connected with the electrical connection line 22, and provides a specific space for the connection of the electrical connection line 22 and the circuit board 11, facilitating the arrangement and management of the line. At the same time, the connection of the electrical connection line 22 and the circuit board 11 is arranged in the first sub-cavity 311, providing a relatively closed and stable environment for the connection.
[0067] The second sub-cavity 312 is also a space region jointly defined by the circuit board 11 and the side wall of the first accommodating cavity 31 in the first direction, and is distributed along the first direction with the first sub-cavity 311. It is generally used to place components with other different functions in the functional module 1, and cooperates with the first sub-cavity 311 to realize various functions of the extension socket 10.
[0068] The second sub-cavity 312 can accommodate components with multiple different functions. For example, the second sub-cavity 312 can place some relays for controlling the on-off of the circuit to realize the power supply control of the electrical equipment. There can also be indicator light modules to display the working state of the extension socket 10 through different colored lights, such as power on, overload protection starting, etc. In addition, some signal processing circuits can also be integrated to communicate with external devices to realize more advanced functions, such as remote control of the switch of the extension socket 10.
[0069] The functional module 1 contains the circuit board 11, and the circuit board 11 and the side wall of the first accommodating cavity 31 divide two different space regions in the first direction, namely the first sub-cavity 311 and the second sub-cavity 312. After the electrical connection line 22 enters the first sub-cavity 311, it establishes an electrical connection with the circuit board 11, which builds an electrical energy transmission channel from the external power supply to the functional module 1. Through this structural design, the internal space of the functional module 1 is utilized reasonably and the circuit connection is arranged in order.
[0070] By dividing the first accommodating cavity 31 into the first sub-cavity 311 and the second sub-cavity 312, the internal space of the functional module 1 is reasonably planned. Different functional components can be placed in corresponding sub-cavities, making the internal structure of the extension socket 10 more compact and orderly, and improving the space utilization. At the same time, this partition design also facilitates subsequent production, maintenance and upgrading. When a functional module 1 needs to be adjusted or replaced, it can be positioned and operated more conveniently.
[0071] In some embodiments, referring to Figure 3 The shell body 3 is recessed to form an accommodating space 35 on the side close to the first sub-cavity 311 in the first direction, and a structure protrusion 36 is arranged in the accommodating space 35. At least part of the side wall of the structure protrusion 36 is spaced apart from the side wall of the accommodating space 35 and defines an accommodating groove 32.
[0072] The accommodation space 35 is an internal space formed by the shell body 3 being recessed along the first direction towards the side close to the first sub-cavity 311. The accommodation space 35 is part of the internal structure of the shell body 3, and this space is used to accommodate the structure protrusions 36, which provide conditions for the formation of the accommodation grooves 32.
[0073] The structure protrusions 36 are structures arranged in the accommodation space 35, and the specific shape and size of the structure protrusions 36 are not limited here.
[0074] Exemplarily, the structure protrusions 36 can be rectangular, semicircular, trapezoidal, etc. The structure protrusions 36 are rectangular protrusions, which can form regular rectangular grooves when the side walls of the accommodation space 35 define the accommodation grooves 32, facilitating the neat arrangement of the electrical connection wires 22. The structure protrusions 36 are semicircular protrusions, which can form grooves with a certain arc, better fitting the natural curved shape of the electrical connection wires 22 and reducing the bending damage to the electrical connection wires 22.
[0075] The height and width of the protrusions can be adjusted according to the thickness and number of the electrical connection wires 22. For thicker electrical connection wires 22 or more electrical connection wires 22 that need to be accommodated, the height and width of the protrusions can be appropriately increased to ensure that the accommodation grooves 32 have enough space to accommodate.
[0076] In some embodiments, some auxiliary structures such as wire clamping grooves or positioning grooves can also be arranged on the structure protrusions 36. The wire clamping grooves can further fix the electrical connection wires 22 and prevent them from sliding randomly in the accommodation grooves 32. The positioning grooves can be used to classify and position different types or purposes of electrical connection wires 22, facilitating users to quickly find the required electrical connection wires 22.
[0077] The shell body 3 is recessed along the first direction towards the side close to the first sub-cavity 311, thereby constructing the accommodation space 35. The structure protrusions 36 are arranged in this accommodation space 35, and part of the side walls of the structure protrusions 36 are not closely fitted with the side walls of the accommodation space 35 but maintain a certain interval, which defines the shape and boundary of the accommodation grooves 32. The design of the accommodation grooves 32 provides space specially used for accommodating the electrical connection wires 22, enabling the electrical connection wires 22 to be placed in order and avoiding the electrical connection wires 22 from being randomly scattered and entangled in the use environment, thereby improving the accommodation convenience of the power strip 10.
[0078] In some embodiments, referring to Figure 4 , the shell body 3 is provided with a wire outlet 37, and the plug-in interfaces 33 are distributed along the circumferential side of the wire outlet 37. The wire outlet 37 and the plug-in interfaces 33 communicate the first sub-cavity 311 and the accommodation space 35, the electrical connection wires 22 pass through the wire outlet 37 and extend into the first sub-cavity 311, and the pins of the plug 21 can pass through the plug-in interfaces 33 and extend into the first sub-cavity 311.
[0079] The wire outlet 37 is a hole formed on the shell body 3, which is a passage for the electrical connecting wire 22 to lead out from the inside of the power strip 10 to the outside. Its main function is to enable the electrical connecting wire 22 to smoothly pass through the shell body 3 and realize connection with the external power supply, while ensuring the sealing and safety between the electrical connecting wire 22 and the shell body 3.
[0080] Exemplarily, the edge of the wire outlet 37 can be designed with a protective sleeve made of soft and elastic insulating material such as rubber or silicone. This not only can prevent the electrical connecting wire 22 from being scratched by the edge when passing out of the wire outlet 37, affecting the insulation performance, but also can play a certain sealing role, reducing the possibility of dust and moisture entering the inside of the power strip 10.
[0081] The plug-in port 33 is located on the shell body 3 and is an opening structure distributed along the periphery of the wire outlet 37. It is adapted to the plug of the plug 21 and used for inserting the plug 21 when stored to realize the fixation of the plug 21.
[0082] The design of the plug-in port 33 distributed along the periphery of the wire outlet 37 makes the connection position of the plug 21 and the electrical connecting wire 22 relatively concentrated, which is convenient for user operation. When stored, the electrical connecting wire 22 can be arranged and put into the accommodation groove 32 of the accommodation space 35 along the direction of the wire outlet 37, and the plug 21 can also be conveniently inserted into the plug-in port 33 for fixation, which greatly improves the storage convenience and use convenience of the power strip 10.
[0083] In some embodiments, referring to Figure 4 , the structure protrusion 36 is provided with an avoidance area 361 and a connecting channel 362. The avoidance area 361 is used to avoid the wire outlet 37 and the plug-in port 33, and the connecting channel 362 connects the avoidance area 361 and the accommodation groove 32. The electrical connecting wire 22 extending from the wire outlet 37 can extend into the accommodation groove 32 along the connecting channel 362.
[0084] The avoidance area 361 is a specially designed area on the structure protrusion 36, and its main function is to avoid spatial conflict with the wire outlet 37 and the plug-in port 33, to ensure that the wire outlet 37 and the plug-in port 33 can normally function, and to provide a reasonable space path for the electrical connecting wire 22.
[0085] The size and shape of the avoidance area 361 are determined according to the size and position of the wire outlet 37 and the plug-in port 33. In order to ensure that the electrical connecting wire 22 can smoothly pass through the avoidance area 361, the space of the avoidance area 361 should be spacious enough, and the edge thereof can be designed to be smoothly transitioned to avoid scratching the electrical connecting wire 22 by sharp corners.
[0086] The connecting channel 362 is a channel structure connecting the avoiding area 361 and the accommodating groove 32, which provides a special path for the electric connecting wire 22 to enter the accommodating groove 32 from the avoiding area 361, ensuring that the electric connecting wire 22 can be orderly arranged and accommodated inside the power strip 10.
[0087] The cross-sectional shape of the connecting channel 362 can be circular, rectangular, or other shapes suitable for the electric connecting wire 22 to pass through. If the electric connecting wire 22 is thicker, a larger cross-section connecting channel 362 can be provided. For thinner electric connecting wire 22, the channel cross-section can be appropriately reduced, but it is necessary to ensure that the electric connecting wire 22 has a certain movement space therein to avoid excessive friction affecting the insulation performance of the electric connecting wire 22.
[0088] The avoiding area 361 is provided on the structure protrusion 36, which is to avoid the positions of the wire outlet 37 and the plug-in port 33 to prevent mutual interference. The connecting channel 362 establishes a connection between the avoiding area 361 and the accommodating groove 32. After the electric connecting wire 22 passes out of the wire outlet 37 from the inside of the power strip 10, it can find a suitable space position through the avoiding area 361, and then enter the accommodating groove 32 through the connecting channel 362 for accommodation, thereby realizing the reasonable arrangement and orderly accommodation of the electric connecting wire 22 inside the power strip 10.
[0089] The avoiding area 361 solves the space conflict problem between the structure protrusion 36 and the wire outlet 37 and the plug-in port 33, making the structure inside the power strip 10 more compact and reasonable. By reasonably planning the path of the electric connecting wire 22, the crossing and confusion of the lines are avoided, the space inside the power strip 10 is fully utilized, and the overall space utilization is improved. The connecting channel 362 provides a clear path for the electric connecting wire 22 to enter the accommodating groove 32, making the accommodation of the electric connecting wire 22 more convenient and fast. When arranging the electric connecting wire 22, the user can easily put it into the accommodating groove 32 according to the designed path, reducing the difficulty of accommodation caused by winding of the lines, and improving the use convenience of the power strip 10.
[0090] In some embodiments, referring to Figure 4 and Figure 5 , the structure protrusion 36 is provided with a first clamping notch 363, and the electric connecting wire 22 can be clamped into the first clamping notch 363.
[0091] The first clamping notch 363 is a notch of a specific shape opened on the structure protrusion 36, and the electric connecting wire 22 can be clamped into the first clamping notch 363. Through this clamping mode, the electric connecting wire 22 is fixed at a specific position to prevent the electric connecting wire 22 from moving randomly in the accommodating groove 32 or the related area.
[0092] In some embodiments, the shell body 3 is provided with a second clamping notch 38, and the electric connecting wire 22 can be clamped into the second clamping notch 38.
[0093] The second clamping notch 38 is a notch structure provided on the shell body 3. Similar to the first clamping notch 363, the electric connection wire 22 can be clamped into the second clamping notch 38. By providing clamping notches at different positions, multi-point fixing of the electric connection wire 22 can be achieved, thereby enhancing the fixing effect.
[0094] The specific shape of the clamping notch is not limited here. For example, it can be semicircular, V-shaped, U-shaped, etc. The semicircular clamping notch has high fitting degree with the circular cross section of the electric connection wire 22, and can provide uniform clamping force. The V-shaped clamping notch can generate certain extrusion force on the electric connection wire 22 when clamping, thereby enhancing the fixing effect.
[0095] The size of the clamping notch can be accurately designed according to the thickness of the electric connection wire 22. For thinner electric connection wires 22, the width and depth of the clamping notch can be correspondingly reduced to ensure tight clamping. For thicker electric connection wires 22, the size of the clamping notch can be increased to ensure that there is enough space to accommodate the electric connection wire 22 and achieve effective fixing.
[0096] At the edge of the clamping notch, a layer of elastic material such as rubber or silicone can be embedded. In this way, when the electric connection wire 22 is clamped in, the elastic material can increase the friction force to prevent the electric connection wire 22 from loosening, and can also avoid damaging the outer skin of the electric connection wire 22.
[0097] The position selection on the shell body 3 can comprehensively consider the direction of the electric connection wire 22 and the overall structural stability. For example, the second clamping notch 38 can be provided near the part where the electric connection wire 22 is prone to sway after passing out of the wire outlet 37, which can better limit the movement range of the electric connection wire 22.
[0098] The second clamping notch 38 and the first clamping notch 363 cooperate with each other in terms of clamping method and fixing force. For example, the first clamping notch 363 is mainly responsible for fixing the electric connection wire 22 near the inside of the accommodation groove 32, and the second clamping notch 38 is responsible for supplementary fixing of the electric connection wire 22 near the outside of the shell body 3, thereby forming a comprehensive fixing system.
[0099] By clamping and fixing the electric connection wire 22 through the first clamping notch 363 and the second clamping notch 38 on the structural protrusion 36 and the shell body 3 respectively, the stability of the electric connection wire 22 inside the power strip 10 is greatly enhanced. Whether in the normal use process of the power strip 10 due to external force pulling, or in the storage process, the electric connection wire 22 can remain in the predetermined position, reducing the problem of unstable electrical connection caused by shaking and displacement, and ensuring the normal power supply of the electrical equipment.
[0100] In some embodiments, please refer to Figure 3The power cord assembly 2 includes a fixing block 23, which fixes at least part of the electric connecting wire 22 to the side wall of the first sub-cavity 311.
[0101] The fixing block 23 is a component in the power cord assembly 2, usually having a certain shape and structure, for fixing the electric connecting wire 22 in a specific position. It is generally made of materials with certain strength and rigidity to ensure that it can provide enough pressure to fix the electric connecting wire 22.
[0102] The fixing block 23 can be designed in various shapes, such as rectangular, arc-shaped, etc., to better fit the shape of the electric connecting wire 22 and the side wall of the first sub-cavity 311. For example, for a circular electric connecting wire 22, an arc-shaped fixing block 23 can provide a larger contact area, thus more evenly applying pressure and enhancing the fixing effect.
[0103] The fixing block 23 can be fixed to the side wall of the first sub-cavity 311 and the electric connecting wire 22 in various ways. For example, it can be fastened by screws, with corresponding screw holes provided on the fixing block 23 and the side wall of the first sub-cavity 311, and screws used to connect the two together while pressing the electric connecting wire 22 in between. In addition, it can also be designed with a buckle, with an elastic buckle provided on the fixing block 23 that can be directly buckled into a buckle slot on the side wall of the first sub-cavity 311, achieving quick installation and fixing of the electric connecting wire 22.
[0104] The power cord assembly 2 includes a fixing block 23, which fixes at least part of the electric connecting wire 22 to the side wall of the first sub-cavity 311. This design ensures the stability of the position of the electric connecting wire 22 in the first sub-cavity 311, guarantees the stability of the connection between the electric connecting wire 22 and the circuit board 11, meets the hanging load requirements of the electric connecting wire 22, satisfies the hanging load test of safety regulations, and thus provides a guarantee for the stable transmission of electric energy.
[0105] In some embodiments, referring to Figure 2 The functional module 1 includes a jack module 12 arranged in the second sub-cavity 312, which is electrically connected to the power cord assembly 2 through the circuit board 11.
[0106] The jack module 12 is a set of jack holes for connecting the plugs 21 of the electric devices, and is the part of the power strip 10 that directly provides the power interface for external electric devices. The types and specifications of the jack holes are determined according to different standards and requirements, such as common national standard, American standard, and European standard jack holes, etc.
[0107] In addition to the common two-hole, three-hole national standard socket, different standard sockets such as American standard and European standard sockets can be integrated to meet the international use requirements. At the same time, some special function sockets can be arranged in the socket module 12, such as sockets with USB charging interfaces, which are convenient for charging mobile devices such as mobile phones and tablet computers.
[0108] In some embodiments, the functional module 1 includes a stretch wire group 13 arranged in the second sub-cavity 312, which is electrically connected with the power line assembly 2 through the circuit board 11.
[0109] The stretch wire group 13 is a kind of wire assembly with stretchable function, which is usually composed of internal wires and external stretchable protective sleeves. It can be retracted and stored when not in use, and can be stretched to the appropriate length when needed, which is convenient for using electrical equipment at different distances.
[0110] The stretch wire group 13 can use an automatic retraction device for its stretch mechanism. When the stretch wire group 13 is used up, it can automatically and slowly retract to the initial position, avoiding the trouble of manual winding. At the same time, reinforced welding or special connection process can be used at the internal wire connection of the stretch wire, to ensure that the wire connection will not loosen during frequent stretching.
[0111] The length of the stretch wire group 13 can be customized according to different use scenarios, such as short distance for desktop devices and long distance for outdoor or large space device connection. In addition, according to the power demand of the connected device, the appropriate specification of the wire is selected to ensure that the power can be stably transmitted during stretching, and the heating or voltage drop caused by excessive resistance will not occur.
[0112] In some embodiments, the circuit board 11 is provided with a circuit interface 14.
[0113] The circuit interface 14 is an interface arranged on the circuit board 11, which is used to connect other circuit modules, devices or expansion function components. It can be a standard interface type such as USB interface, Type-c interface, etc., or a custom special interface to meet specific circuit connection requirements. In addition, according to different application scenarios, an Ethernet interface is added for network device connection, an HDMI interface is added for audio and video device connection, etc. These interfaces can be adapted to the power line assembly 2 and other functional modules 1 through the conversion circuit on the circuit board 11, realizing the interconnection between different devices.
[0114] By setting different components such as the socket module 12 and the stretchable wire set 13 in the second sub-cavity 312, and setting the circuit interface 14 on the circuit board 11, the power strip 10 has multiple functions. Users can choose to use different functions according to actual needs to meet diversified power consumption scenarios, such as simultaneously powering multiple different types of electrical equipment, or using stretchable wires to connect equipment at a remote location when needed, thereby improving the practicality and applicability of the power strip 10.
[0115] In some embodiments, referring to Figure 4 The accommodating groove 32 is annular.
[0116] The diameter of the annular accommodating groove 32 can be designed according to the overall size of the power strip 10 and the length of the electrical connecting wire 22. If the power strip 10 is small in size, a relatively small compact annular shape can be designed to adapt to limited space; for a larger size power strip 10, the diameter of the annular accommodating groove 32 can be increased accordingly to accommodate longer electrical connecting wires 22.
[0117] The annular accommodating groove 32 can be located in the central region of the shell body 3, so that the electrical connecting wire 22 is wound around the center of the power strip 10; or it can be eccentrically arranged near one side of the shell body 3, in combination with other structural designs, to optimize the internal space utilization of the power strip 10.
[0118] The groove wall of the annular accommodating groove 32 can be smooth to reduce the frictional resistance of the electrical connecting wire 22 during storage and removal; or some small textures or grooves can be provided on the groove wall, which can increase the friction between the electrical connecting wire 22 and the groove wall to prevent the electrical connecting wire 22 from sliding randomly in the groove. The grooves can also guide the arrangement of the electrical connecting wire 22, so that the electrical connecting wire 22 is arranged more neatly in the annular groove.
[0119] The groove bottom of the annular accommodating groove 32 can be designed to have a certain elasticity, such as rubber or silicone material. When the electrical connecting wire 22 is placed in the groove, the elastic groove bottom can provide a certain buffering effect to protect the electrical connecting wire 22 from being scratched by the hard bottom of the groove. At the same time, the elastic groove bottom can also exert a certain pressure on the electrical connecting wire 22 to further fix the position of the electrical connecting wire 22 in the groove.
[0120] In order to facilitate the entry and exit of the electrical connecting wire 22, the annular accommodating groove 32 needs to be provided with a suitable opening. The size of the opening should be moderate, which can ensure that the electrical connecting wire 22 can pass through smoothly, and cannot be too large to cause the electrical connecting wire 22 to easily slide out of the opening after being stored. The opening can be designed to be inclined or smooth in shape, which is convenient for the insertion and removal of the electrical connecting wire 22.
[0121] The annular accommodating groove 32 can accommodate the electric connecting wire 22 in a relatively compact manner. Compared with a linear or other irregular accommodating groove 32, the annular design can make full use of the space, so that the relatively long electric connecting wire 22 can be orderly arranged in a relatively concentrated area. This not only improves the accommodation efficiency, but also makes the power strip 10 look more neat and beautiful as a whole, thereby enhancing the visual appeal of the product.
[0122] In some embodiments, referring to Figure 4 The interference amount between the fastening protrusions 34 and the electric connecting wire 22 is greater than 0 mm and less than or equal to 0.4 mm.
[0123] The specific interference amount between the fastening protrusions 34 and the electric connecting wire 22 is not limited herein, and for example, can be 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, etc.
[0124] The electric connecting wire 22 is interference-fitted with the fastening protrusions 34, and in addition, the twisted stress of the electric connecting wire 22 itself can further fix the electric connecting wire 22 inside the misaligned bone positions.
[0125] The interference amount greater than 0 mm means that the interval size between the fastening protrusions 34 is indeed smaller than the size of the part of the electric connecting wire 22 that is fitted therewith, so that a certain pressure can be generated to fix the electric connecting wire 22. The interference amount greater than 0 mm and less than or equal to 0.4 mm enables the fastening protrusions 34 to effectively fix the electric connecting wire 22 while not damaging the electric connecting wire 22 due to excessive pressure.
