Technical Field

[0001] This utility model relates to the field of anti-interference power cord technology, specifically an anti-interference power cord with multiple shielding layers. Background Technology

[0002] Power cords are wires that transmit current. The current transmission method is usually point-to-point. Power cords can be divided into AC power cords and DC power cords according to their uses. AC power cords are usually wires that carry higher voltage alternating current. Some existing power cords require a certain level of electromagnetic shielding due to the usage environment and requirements, while some power cords do not have the function of protecting the power cord from electromagnetic interference. In order to meet the needs of the market, there is a need for an anti-interference power cord with multiple shielding layers.

[0003] Existing anti-interference power cords lack sufficient anti-interference shielding performance, failing to achieve double electromagnetic shielding and thus compromising usability. Furthermore, their overheat protection needs improvement, hindering the rapid dissipation of heat from the first connector, compromising safety. Additionally, existing anti-interference power cords typically lack protection at the connection between the cord and the second connector, making this connection prone to breakage and impacting the cord's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide an anti-interference power cord with multiple shielding layers to solve the problems mentioned in the background art, such as insufficient anti-interference shielding performance, need for further improvement in overheat protection, and lack of protection for the connection between the power cord body and the second plug.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-interference power cord with multiple shielding layers, comprising a power cord body, a connector mounted on the surface of the power cord body, a first plug provided on one side of the connector, the connector being inserted into the interior of the first plug, a second plug mounted on the surface of the other end of the power cord body, an inner wire core provided inside the power cord body, a high-efficiency heat dissipation mechanism provided inside the first plug, a durable protection mechanism provided on the surfaces of the power cord body and the second plug, and a double shielding mechanism provided on the inner wall of the inner wire core.

[0006] Preferably, the surface of the power cord body is covered with a corrosion-resistant layer for wear-resistant protection of the power cord body surface, and multiple sets of wires are arranged inside the inner core. The wires are evenly distributed inside the inner core, the wires are copper conductors, the surface of the wires is covered with an insulating sleeve, and the space between the inner core and the wires is filled with a filler material.

[0007] Preferably, the high-efficiency heat dissipation mechanism consists of heat dissipation fins, heat dissipation holes, heat conduction plates, mounting studs, and a frame plate. The first plug has a frame plate inside, and a heat conduction plate for heat conduction is installed on the surface of the frame plate. The frame plate is connected to the inner wall of the first plug by mounting studs.

[0008] Preferably, the surface of the frame plate is fitted with multiple sets of heat dissipation fins by screws, the surface of the heat dissipation fins is in contact with the surface of the heat-conducting plate, and the inner wall of the first plug is provided with multiple sets of heat dissipation holes for heat dissipation, the heat dissipation holes being connected to the interior of the first plug.

[0009] Preferably, the durable protection mechanism consists of a first rubber protective sleeve, a protective plate, a second rubber protective sleeve, and a protective pad. A protective plate is provided on one side of the power cord body and the second plug. The first rubber protective sleeve is installed on the surface of the protective plate, and the second rubber protective sleeve is also installed on the surface of the protective plate.

[0010] Preferably, both the second rubber protective sleeve and the first rubber protective sleeve are fitted onto the surface of the power cord body and the second plug. The first rubber protective sleeve and the second rubber protective sleeve are made of rubber. Protective pads are installed on the inner walls of the first rubber protective sleeve and the second rubber protective sleeve. The surface of the protective pads is in contact with the surface of the second plug.

[0011] Preferably, the double shielding mechanism includes an inner insulation layer, an outer insulation layer, an outer shielding layer, and an inner shielding layer. The inner core has an outer insulation layer inside, and the outer insulation layer is adhered to the surface of the outer insulation layer.

[0012] Preferably, an inner shielding layer is adhered to the surface of the inner insulation layer away from the outer insulation layer, and an outer shielding layer is disposed inside the inner core. The surface of the outer shielding layer is adhered to the surface of the inner shielding layer away from the inner insulation layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the anti-interference power cord with multiple shielding layers not only enables the power cord body to achieve double electromagnetic shielding when used, making the power cord body have good usability, but also enables the heat inside the first plug to be dissipated quickly, making the anti-interference power cord safer to use. In addition, it protects the connection between the power cord body and the second plug, preventing damage to the connection between the power cord body and the second plug that would affect the service life of the power cord body.

[0014] 1. By incorporating a double shielding mechanism, the power cord body possesses dual insulation performance thanks to the inner and outer insulation layers. The corrosion-resistant layer further enhances its corrosion resistance, preventing environmental factors from damaging the surface of the power cord. The combined effect of the outer and inner shielding layers achieves double electromagnetic shielding, ensuring excellent usability and realizing the double shielding function of the anti-interference power cord. This ensures the power cord body achieves double electromagnetic shielding during use, resulting in excellent usability.

[0015] 2. By setting up a high-efficiency heat dissipation mechanism, the bracket plate and heat conduction plate are installed inside the first plug by mounting studs. Under the action of the heat conduction plate, the heat generated by the internal components of the first plug during operation is conducted to the surface of the heat dissipation fins, and the heat dissipation fins are used for efficient heat dissipation. The heat dissipation is dissipated into the interior of the first plug through the heat dissipation holes, thereby achieving a high-efficiency heat dissipation effect for the interior of the first plug. This realizes the overheat protection function of the anti-interference power cord, so that the heat inside the first plug can be quickly dissipated when the anti-interference power cord is used, making the anti-interference power cord safer to use.

[0016] 3. By incorporating a durable protection mechanism, the user pushes the first and second rubber protective sleeves, which then cover the connection between the power cord body and the second plug. The protective pads protect the surface of the second plug. The combined action of the first and second rubber protective sleeves protects the connection between the power cord body and the second plug, preventing damage such as wire bending when the second plug is plugged in or unplugged from the device. This achieves the function of protecting the connection between the power cord body and the second plug during the use of the anti-interference power cord, preventing damage that could affect the lifespan of the power cord body.

In addition, the terms "first", "second", "third", "upper", "lower", "left", "right", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] The structure of the anti-interference power cable with multiple shielding layers provided by this utility model is as follows: Figures 1 to 3 As shown, the device includes a power cord body 1, a connector 11 mounted on the surface of the power cord body 1, a first plug 12 on one side of the connector 11, the connector 11 being inserted into the first plug 12, a second plug 13 mounted on the surface of the other end of the power cord body 1, a corrosion-resistant layer 16 covering the surface of the power cord body 1 for wear-resistant protection, an inner core 15 inside the power cord body 1, multiple sets of wires 14 inside the inner core 15, the wires 14 being evenly distributed inside the inner core 15, the wires 14 being copper conductors, the surface of the wires 14 being covered with an insulating sleeve 18, and a filler material 17 filling the space between the inner core 15 and the wires 14.

[0026] Furthermore, such as Figure 2 and Figure 4 As shown, the first plug 12 is equipped with a high-efficiency heat dissipation mechanism 2. The high-efficiency heat dissipation mechanism 2 consists of heat dissipation fins 21, heat dissipation holes 22, heat conduction plate 23, mounting studs 24 and a frame plate 25. The first plug 12 is equipped with a frame plate 25. The surface of the frame plate 25 is equipped with a heat conduction plate 23. The frame plate 25 is connected to the inner wall of the first plug 12 by mounting studs 24. Multiple sets of heat dissipation fins 21 are installed on the surface of the frame plate 25 by screws. The surface of the heat dissipation fins 21 is in contact with the surface of the heat conduction plate 23. Multiple sets of heat dissipation holes 22 are opened on the inner wall of the first plug 12. The heat dissipation holes 22 are connected to the interior of the first plug 12.

[0027] In practice, when the first plug 12 is plugged into the socket for a long time, the internal temperature will continue to rise. In order to further improve the heat dissipation effect inside the first plug 12, the mounting plate 25 and the heat conduction plate 23 are installed inside the first plug 12 by mounting studs 24. Under the action of the heat conduction plate 23, the heat generated by the internal components of the first plug 12 during operation is conducted to the surface of the heat dissipation fins 21, and the heat dissipation fins 21 are used for efficient heat dissipation. The heat dissipation is dissipated from the inside of the first plug 12 through the heat dissipation holes 22, thereby achieving efficient heat dissipation effect inside the first plug 12, so as to realize the function of preventing overheating of the anti-interference power cord.

[0028] Furthermore, such as Figure 2 and Figure 5As shown, a durable protection mechanism 3 is provided on the surface of the power cord body 1 and the second plug 13. The durable protection mechanism 3 consists of a first rubber protective sleeve 31, a protective plate 32, a second rubber protective sleeve 33, and a protective pad 34. A protective plate 32 is provided on one side of the power cord body 1 and the second plug 13. The first rubber protective sleeve 31 is installed on the surface of the protective plate 32, and the second rubber protective sleeve 33 is also installed on the surface of the protective plate 32. The second rubber protective sleeve 33 and the first rubber protective sleeve 31 are both fitted on the surface of the power cord body 1 and the second plug 13. The first rubber protective sleeve 31 and the second rubber protective sleeve 33 are made of rubber. A protective pad 34 is installed on the inner wall of the first rubber protective sleeve 31 and the second rubber protective sleeve 33. The surface of the protective pad 34 is in contact with the surface of the second plug 13.

[0029] In practice, the user places the first rubber protective sleeve 31 and the second rubber protective sleeve 33 on the surface of the protection plate 32 onto the surface of the power cord body 1 and the second plug 13. The user pushes the first rubber protective sleeve 31 and the second rubber protective sleeve 33, at which point the first rubber protective sleeve 31 and the second rubber protective sleeve 33 are placed at the connection between the power cord body 1 and the second plug 13. The protective pad 34 on the inner wall of the first rubber protective sleeve 31 and the second rubber protective sleeve 33 moves to contact the surface of the second plug 13. Under the action of the protective pad 34, the surface of the second plug 13 is protected. Under the combined action of the first rubber protective sleeve 31 and the second rubber protective sleeve 33, the connection between the power cord body 1 and the second plug 13 can be protected, avoiding the phenomenon of wire bending and damage when the second plug 13 is plugged in and unplugged from the device, so as to realize the function of the anti-interference power cord protecting the connection between the power cord body 1 and the second plug 13.

[0030] Furthermore, such as Figure 3 and Figure 6 As shown, the inner wall of the inner core 15 is provided with a double shielding mechanism 4. The double shielding mechanism 4 includes an inner insulation layer 41, an outer insulation layer 42, an outer shielding layer 43, and an inner shielding layer 44. The inner core 15 is provided with an outer insulation layer 42. The inner insulation layer 41 is adhered to the surface of the outer insulation layer 42. The inner shielding layer 44 is adhered to the surface of the inner insulation layer 41 away from the outer insulation layer 42. The inner core 15 is provided with an outer shielding layer 43. The surface of the outer shielding layer 43 is adhered to the surface of the inner shielding layer 44 away from the inner insulation layer 41.

[0031] In practice, the dual insulation layer 41 and the outer insulation layer 42 provide the power cord body 1 with dual insulation performance. The corrosion-resistant layer 16 provides the power cord body 1 with good corrosion resistance, preventing external environmental factors from causing corrosion damage to the surface of the power cord body 1. The combined action of the outer shielding layer 43 and the inner shielding layer 44 achieves the effect of dual electromagnetic shielding for the power cord body 1, enabling the power cord body 1 to have good usability and realize the function of dual shielding for anti-interference power cords.

[0032] Working principle: When in use, first place the power cord body 1 in the designated position. With the double setting of the inner insulation layer 41 and the outer insulation layer 42, the power cord body 1 can have double insulation performance. Under the action of the corrosion-resistant layer 16, the power cord body 1 can have good corrosion resistance, avoiding the corrosion damage to the surface of the power cord body 1 caused by external environmental factors. With the combined action of the outer shielding layer 43 and the inner shielding layer 44, the power cord body 1 can achieve the effect of double electromagnetic shielding, so that the power cord body 1 can have good usability, thus realizing the function of double shielding of anti-interference power cord. Therefore, when using the anti-interference power cord, the power cord body 1 can achieve the effect of double electromagnetic shielding, so that the power cord body 1 can have good usability.

[0033] Subsequently, when the first plug 12 is plugged into the socket for extended periods, its internal temperature will continuously rise. To further improve the heat dissipation effect inside the first plug 12, the mounting plate 25 and the heat-conducting plate 23 are installed inside the first plug 12 using mounting studs 24. Under the action of the heat-conducting plate 23, the heat generated by the internal components of the first plug 12 during operation is conducted to the surface of the heat dissipation fins 21, and then efficiently dissipated through the heat dissipation fins 21. The heat dissipation is then dissipated through the heat dissipation holes 22, thus achieving efficient heat dissipation inside the first plug 12 and realizing the overheat protection function of the anti-interference power cord. This allows the anti-interference power cord to quickly dissipate the heat inside the first plug 12 during use, making it safer to use. The inner wall of the heat dissipation holes 22 is equipped with a dust filter to prevent dust from entering the interior of the first plug 12 through the heat dissipation holes 22.

[0034] Subsequently, the user places the first rubber protective sleeve 31 and the second rubber protective sleeve 33 on the surface of the protection board 32 onto the surface of the power cord body 1 and the second plug 13. The user pushes the first rubber protective sleeve 31 and the second rubber protective sleeve 33, at which point the first rubber protective sleeve 31 and the second rubber protective sleeve 33 are placed at the connection between the power cord body 1 and the second plug 13. The protective pad 34 on the inner wall of the first rubber protective sleeve 31 and the second rubber protective sleeve 33 moves to contact the surface of the second plug 13. Under the action of the protective pad 34, the surface of the second plug 13 is protected. Under the combined action of the first rubber protective sleeve 31 and the second rubber protective sleeve 33, the connection between the power cord body 1 and the second plug 13 can be protected, avoiding the phenomenon of wire breakage and damage when the second plug 13 is plugged in and unplugged from the device. This realizes the function of the anti-interference power cord protecting the connection between the power cord body 1 and the second plug 13. Thus, when using the anti-interference power cord, the connection between the power cord body 1 and the second plug 13 can be protected, avoiding the phenomenon of wire breakage and damage to the connection between the power cord body 1 and the second plug 13, which would affect the service life of the power cord body 1. Finally, the use of the anti-interference power cord is completed.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
