Description

Technical Field

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

[0002] Currently, most power cords used in household appliances and power strips on the market have a circular or elliptical cross-section in the radial direction. While this cross-section offers good flexibility in cable management, it can also lead to messy and inconvenient cable organization. Furthermore, power cords with a circular or elliptical cross-section are generally thicker. When these power cords are installed flush against a wall or other flat surface, they are tangential to the surface, resulting in a small contact area. Consequently, these power cords are more prone to detaching from walls or other flat surfaces when installed flush against them. Utility Model Content

This outer sheath structure is relatively flat, with a large contact surface with the wall or other flat surface, making it easy to attach to the wall or other flat surface and preventing it from falling off. Furthermore, because there is a gap between the wire core and the mounting hole, the wire core can move within the outer sheath structure, allowing the utility model to make turns in multiple directions when routing the cable.

[0029] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] See Figures 1-6This utility model discloses a power cord, including: a wire core 10; an outer sheath structure 20, which is sleeved on the outside of the wire core 10, and the radial cross-section of the outer sheath structure 20 is in the shape of an "I"; the outer sheath structure 20 is provided with mounting holes 201 inside, which are arranged along the extension direction of the outer sheath structure 20, and the mounting holes 201 correspond one-to-one with the wire core 10, with the wire core 10 passing through the corresponding mounting hole 201, and there is a gap between the wire core 10 and the mounting hole 201.

[0033] This utility model features an outer sheath structure 20 with a radial cross-section in the shape of an "I". This outer sheath structure 20 is relatively flat, with a large contact surface with the wall or other flat surfaces, making it easy to attach to the wall or other flat surfaces and preventing it from easily falling off. Furthermore, because there is a gap between the wire core 10 and the mounting hole 201, the wire core 10 can move within the outer sheath structure 20, allowing the utility model to make turns in multiple directions when routing wiring.

[0034] It should be noted that the ability of the power cord to bend in multiple directions during wiring refers to the fact that the power cord as a whole can bend along the directions of up, down, left, right, front, and back. The power cord can be bent directly as a whole, or when bending, the outer sheath 20 can be cut off at the point where the bend is needed, the internal wire core 10 can be pulled out, and the pulled-out wire core 10 can be bent along the target direction. This power cord is particularly suitable for wiring along walls or other flat surfaces.

[0035] In this embodiment of the invention, the outer diameter of the wire core 10 is smaller than the inner diameter of the mounting hole 201.

[0036] Specifically, the radial cross-sections of the wire core 10 and the mounting hole 201 are both circular, or the radial cross-sections of the wire core 10 and the mounting hole 201 are both square, irregular, or other shapes, or the radial cross-section of the wire core 10 is circular and the radial cross-section of the mounting hole 201 is square. The radial cross-sections of the wire core 10 and the mounting hole 201 are determined according to the actual application scenario and are not limited thereto.

[0037] When the radial cross-sections of the wire core 10 and the mounting hole 201 are the same, the shapes of the wire core 10 and the mounting hole 201 are adapted to each other; furthermore, when the radial cross-sections of the wire core 10 and the mounting hole 201 are both circular, it is convenient for the wire core 10 to move, for example, it is convenient to pull the wire core 10; since the radial cross-sections of the wire core 10 and the mounting hole 201 are both circular, the wire core 10 and the mounting hole 201 can be set on the same central axis, and there is an equal gap between the wire core 10 and the mounting hole 201 in all directions. When it is necessary to bend the power cord, the power cord can be bent from multiple directions.

[0038] If the inner diameter of the mounting hole 201 is much larger than the outer diameter of the wire core 10, that is, if the maximum gap between the wire core 10 and the mounting hole 201 is too large, the wire core 10 is likely to separate from the outer sheath structure 20 during use. If the outer diameter of the wire core 10 is close to the inner diameter of the mounting hole 201, that is, if the maximum gap between the wire core 10 and the mounting hole 201 is too small, the wire core 10 and the mounting hole 201 will interfere with each other, and the wire core 10 will have difficulty moving within the mounting hole 201. As a result, the bending direction and bending angle of the power cord will be restricted. Therefore, it is necessary to limit the range of values ​​for the gap between the wire core 10 and the mounting hole 201.

[0039] Specifically, the radial cross-sections of the wire core 10 and the mounting hole 201 are both circular, the outer diameter of the wire core 10 is D1, the inner diameter of the mounting hole 201 is D2, D2>D1, and 1mm≤D2-D1≤8mm.

[0040] Furthermore, 2mm≤D2-D1≤4mm.

[0041] Specifically, the wire core 10 is a flexible wire core 10, which is formed by multiple metal cores and is flexible and can be bent. For example, the wire core 10 is formed by multiple copper cores; of course, the wire core 10 can also be formed by multiple iron cores, depending on the actual application scenario, and is not limited thereto.

[0042] Specifically, the outer skin structure 20 is a flexible outer skin structure 20, which is made of flexible insulating plastics such as PVC plastic or PE plastic, so that the outer skin structure 20 can be bent.

[0043] Since the core 10 itself is a flexible core 10 and the outer sheath structure 20 is a flexible outer sheath structure 20, the core 10 has a certain degree of bending and undulation during the installation process and is not a completely straight line, and 1mm≤D2-D1≤8mm. The core 10 can be supported inside the outer sheath structure 20. At this time, the core 10 can also move relative to the outer sheath structure 20. When it is necessary to pull the core 10 to be bent, the core 10 can also be pulled. Of course, in some application scenarios, a separate core 10 fixing structure can be set to fix the core 10 to prevent the core 10 from separating from the outer sheath structure 20. Alternatively, the head of the core 10 can be bent to make it snap into the outer sheath structure 20 to prevent the core 10 from separating from the outer sheath structure 20.

[0044] In this embodiment of the present invention, a connecting seam 202 is provided between adjacent mounting holes 201, the connecting seam 202 connects two adjacent mounting holes 201, and the connecting seam 202 is provided along the extension direction of the mounting hole 201.

[0045] Because a connecting seam 202 is provided between adjacent mounting holes 201, the outer sheath structure 20 is broken at this point. That is, a portion of the outer sheath structure 20 between two adjacent mounting holes 201 forms a cross-section at this point, and this portion of the outer sheath structure 20 between two adjacent mounting holes 201 can swing in the direction of the mounting hole 201 to undergo elastic deformation. Compared to the case where there is no connecting seam 202 between adjacent mounting holes 201, the range of elastic deformation at the same position is larger when the connecting seam 202 is provided. When the wire core 10 in the mounting hole 201 moves, the wire core 10 can be squeezed in the direction of the connecting seam 202, thereby increasing the gap size between the wire core 10 and the mounting hole 201. In other words, the connecting seam 202 provided between adjacent mounting holes 201 makes this position have an elastic gap in the direction of the adjacent mounting hole 201.

[0046] It should be noted that the width of the connecting seam 202 should not be too large. If the width of the connecting seam 202 is too large, the mounting hole 201 will not be able to effectively limit the wire core 10.

[0047] In this embodiment of the utility model, the outer skin structure 20 has at least two mounting holes 201 inside, all mounting holes 201 are arranged in a row, all mounting holes 201 are arranged in a straight line, and the radial cross section of the outer skin structure 20 is in a straight line.

[0048] See appendix Figure 3 The power cord has three cores 10. To make the power cord structure more compact, the three cores 10 can be arranged along the length of the radial cross-section of the outer sheath structure 20. In other words, the three cores 10 can be arranged along the radial cross-section of the outer sheath structure 20. Figure 3 Arranged in the Y direction.

[0049] Specifically, the axial length of the connecting seam 202 is equal to the axial length of the mounting hole 201. The connecting seam 202 and the center line connecting multiple mounting holes 201 are coaxially arranged, so the thickness of the outer sheath structure 20 can be made smaller, and the power cord as a whole can be made thinner, which is conducive to the flattening of the power cord, thus making it easier to use the power cord in a limited space.

[0050] In this embodiment of the invention, the back of the outer skin structure 20 is provided with a connection structure for connecting to the connection target.

[0051] In this embodiment of the invention, the connecting structure is an adhesive tape or a locking screw.

[0052] Specifically, the adhesive includes an adhesive, and the back of the outer sheath structure 20 is a flat surface with a large surface area. Users can use the adhesive to stick the outer sheath structure 20 to a wall or other flat surface. Of course, in some application scenarios, locking screws can also be used to lock the outer sheath structure 20, thereby installing the power cord.

[0053] In an embodiment of the present utility model, the outer skin structure 20 includes at least two sub-outer skin units 203, and at least two sub-outer skin units 203 are arranged at intervals along the extending direction of the wire core 10, and the wire core 10 forms a bend at the gap between two adjacent sub-outer skin units 203.

[0054] Specifically, the number of the sub-outer skin units 203 is determined according to the actual requirements of the bend needed.

[0055] In an embodiment of the present utility model, the power cord further includes a turning buckle 30, and the turning buckle 30 is arranged at the bending position of the wire core 10. The turning buckle 30 includes a first connecting portion and a second connecting portion which are connected to each other; the first connecting portion is sleeved outside one of the two adjacent sub-outer skin units 203, and the second connecting portion is sleeved outside the other of the two adjacent sub-outer skin units 203.

[0056] Specifically, the turning angle of the turning buckle 30 is 90°, and the turning angle of the turning buckle 30 can also be other angles such as 60° and 120°. The turning angle of the turning buckle 30 is set according to the actual bending angle of the power cord.

[0057] Since the power cord can be directly bent as a whole, or when bending, the outer skin structure 20 of the power cord can be cut at the position where bending is needed, the internal wire core 10 is pulled out and the pulled-out wire core 10 is bent along the target direction. Compared with directly bending the power cord as a whole, by adopting the method of cutting the outer skin structure 20 of the power cord at the position where bending is needed, pulling out the internal wire core 10 and bending the pulled-out wire core 10 along the target direction, the power cord can have more bending directions and larger bending angles. In order to prevent the wire core 10 from being exposed and deformed due to exposure, the above-mentioned turning buckle 30 is provided to support the wire core 10.

[0058] In an embodiment of the present utility model, a card slot 301 for supporting the wire core 10 is provided on the turning buckle 30; and / or, the turning buckle 30 includes a first buckling portion 302 and a second buckling portion 303 which are connected to each other.

[0059] Specifically, a tooth-like structure 304 for preventing detachment is provided at the connection position between the first buckling portion 302 and the second buckling portion 303.

[0060] Specifically, referring to Appendix Figure 5 and Appendix Figure 6 , the first buckling portion 302 is a "one" - shaped structure, the second buckling portion 303 is an "n" - shaped structure, and after the first buckling portion 302 and the second buckling portion 303 are buckled, an accommodation space for passing the wire is formed inside.

[0061] Of course, both the first fastening part 302 and the second fastening part 303 can be of an "n" shape.

[0062] Because the connection between the first fastening part 302 and the second fastening part 303 is provided with a toothed structure 304 to prevent detachment, the first fastening part 302 and the second fastening part 303 are not easy to detach after being fastened together. If it is necessary to remove the turning buckle 30, the user can pry open the two sides of the second fastening part 303 to separate the first fastening part 302 and the second fastening part 303 from each other, thereby removing the second fastening part 303 and the first fastening part 302.

[0063] In this embodiment of the invention, the outer skin structure 20 is cut to form at least two sub-outer skin units 203.

[0064] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
