Technical Field
[0001] This utility model relates to the field of plug technology, specifically a national standard non-polar two-prong bent female plug for concealed installation. Background Technology
[0002] A plug is a connector in general electronic products and a pin in electrical appliances. Household AC power plugs and sockets have a male connector with a protruding rod or copper plate, which is physically inserted into a female connector with a slot or recess. Size is a crucial technical requirement affecting the safe use of plugs, sockets, and adapters, ensuring they meet universal interchangeability requirements and preventing misinsertion. Incorrect dimensions can affect user experience or cause poor contact, misinsertion, and other hazards, ranging from equipment damage to fires and electric shocks.
[0003] Fiber optic networks are communication networks that use optical fibers to transmit optical signals. Optical fiber, often simply called optical fiber, is a medium for transmitting optical signals. Communication networks have a long history of development, aiming to transmit information from one place to another, regardless of the distance between them. Modern communication networks typically use electromagnetic waves with frequencies ranging from several megahertz (MHz) to several hundred terahertz (THz) to carry information. Based on the range of electromagnetic waves used, communication technologies can be divided into electrical communication and optical communication. Electrical communication uses lower electromagnetic wave frequencies and is generally divided into wired and wireless communication; these are two fairly mature communication technologies. Optical communication technology, on the other hand, represents the latest achievement in local communication technology development, using higher optical wave frequencies, thus greatly expanding the performance of modern communication.
[0004] In the process of promoting fiber optic networks, although operators and equipment manufacturers have continuously made various optimizations based on the actual situation of customers, improving from early desktop equipment to wall-mounted equipment, in actual application, whether it is desktop installation or wall-mounted installation, the power connection of external power adapters will affect the aesthetics. This can easily affect consumers' continued acceptance of fiber optic networks when new products are launched in the market. Utility Model Content
[0005] To overcome the shortcomings of existing fiber optic network equipment, whether desktop or wall-mounted, where the installation of external power adapters affects aesthetics and can negatively impact consumer acceptance of fiber optic networks during product launches, this application provides a concealed installation standard non-polarized two-prong angled female plug. By installing two junction boxes within the wall—one for wiring the socket terminals and supporting current flow—and the other for storing the power adapter, the power adapter can be directly connected to the socket terminals via the plug body and wire. This eliminates the need to plug the adapter into the socket's surface, resulting in a more aesthetically pleasing wall surface and improved user experience when the router is wall-mounted.
[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0007] A national standard non-polar two-pronged female plug for concealed installation includes a female plug body, a power adapter and a cord collection box, with plug wires provided on the surface of the female plug body.
[0008] The power adapter has adapter cables on its surface;
[0009] There are two cable reel boxes;
[0010] The front of each of the two cable collection boxes is provided with a socket that fits against the wall and a cover, and the top of the cover is machined with a first wire passage groove;
[0011] The power adapter has a contact point that is plugged into the inside of the angled female plug body and is connected to the inside of the cable tray. One end of the plug wire is connected to the inside of the socket, and one end of the adapter wire is passed through the inside of the first wire slot.
[0012] In one possible implementation, one end of the plug wire has a bare wire tail, which is obtained by stripping the wire, and the socket has multiple terminals inside; the bare wire tail on the plug wire is connected to the corresponding terminal, so that the socket can directly transmit current to the inside of the plug wire through the terminal.
[0013] In one possible implementation, the take-up box has a second wire-passing slot on all four sides. The power adapter and the main body of the right-angle female plug are located inside the same take-up box. One end of the plug wire on the main body of the right-angle female plug passes through the second wire-passing slots at two horizontally adjacent positions of the two take-up boxes and enters the interior of another take-up box.
[0014] In one possible implementation, one end of the adapter wire passing through the first wiring slot is connected to the power interface on the router or gateway, and a slot is cut out inside the wall to support the installation of the gateway storage box.
[0015] In one possible implementation, fastening seats are provided on the inner walls of both sides of the two cable retractors, and locking bolts are provided inside both sides of the socket; one end of each of the two locking bolts on the socket is connected to one of the two fastening seats inside a cable retractor, thereby fixing the socket to the wall surface.
[0016] In one possible implementation, two locking bolts are also disposed inside the sealing cover, the two locking bolts are arranged symmetrically on the left and right, and the first wire slot is located at the center of the top edge of the sealing cover, the first wire slot supporting the top of the sealing cover can be switched to the bottom.
[0017] In one possible implementation, the two locking bolts are threadedly connected to two fastening seats inside the cable tray, respectively, to fix the socket to the wall surface and allow one end of the adapter wire to pass through the inside of the first cable slot.
[0018] The beneficial effects of this application are as follows:
[0019] Firstly, this solution involves installing two junction boxes inside the wall. One box is used for wiring the terminals on the socket, supporting the current flow into the socket's interior. The other box is used to store the power adapter. When the right-angle female plug is connected to the contact point on the power adapter, and the bare wire end of the plug's cable is connected to the corresponding terminal, the power adapter can directly draw power from the terminals inside the socket using the right-angle female plug and the plug's cable. This eliminates the need to plug the power adapter's contact point into the hole on the socket's surface. This makes the wall-mounted router in the fiber optic network look more aesthetically pleasing and improves the user experience during daily use (and makes it less likely to be quickly replaced by new products due to differences in accessories, structure, etc.).
[0020] Secondly, in this solution, by positioning the first cable tray at the center of the top of the two locking bolts and machining it to the center of the top edge of the cover, when the cover is installed upside down, the first cable tray can face the bottom. This makes it convenient to pass the adapter cable through the top-facing first cable tray when the router is wall-mounted above the socket, and through the bottom-facing first cable tray when it is below the socket, which is flexible and convenient.

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0027] Example 1:
[0028] This embodiment describes the specific structure of a national standard non-polarized two-prong bent female plug for concealed installation. See details below. Figures 1-3 As shown, it includes a bent female plug body 11, a power adapter 6 and two cable trays 10. The surface of the bent female plug body 11 is provided with plug wires 8, the surface of the power adapter 6 is provided with adapter wires 3, and the front of the two cable trays 10 is respectively provided with a wall-mounted socket 1 and a sealing cover 5. The top of the sealing cover 5 is machined with a first wire-passing groove 4.
[0029] In this way, by connecting the contact points (i.e. the two contact pins) on the power adapter 6 to the inside of the bent female plug body 11, the connection is completed inside the cable box 10, and no protrusion is formed on the surface of the socket 1 and the adapter wire 3, thus ensuring that only the wall-mounted router is on the wall.
[0030] Secondly, one end of the plug wire 8 has a bare wire tail, which is obtained by stripping the wire. The socket 1 has multiple terminals inside. By connecting the bare wire tail on the plug wire 8 to the corresponding terminals, the socket 1 can directly transmit current to the inside of the plug wire 8 through the terminals, ensuring that one end of the plug wire 8 is in a stable state connected to the inside of the socket 1. When one end of the adapter wire 3 is passed through the first wire slot 4 and connected to fiber optic network devices such as routers, the messy parts of the adapter wire 3 can be stored inside the cable management box 10 as much as possible, keeping the wall clean.
[0031] Furthermore, the cord retractor 10 is equipped with second wire slots 9 on all four sides. By placing the power adapter 6 and the right-angle female plug body 11 inside the same cord retractor 10, and having one end of the plug wire 8 on the right-angle female plug body 11 pass through the second wire slots 9 at the horizontally adjacent positions of the two cord retractors 10 to enter the interior of another cord retractor 10, it is possible to avoid the power adapter 6 and the socket 1 occupying the same cord retractor 10, which would result in too many wires inside the cord retractor 10 and affect the assembly and electrical safety of the socket 1.
[0032] Furthermore, fastening seats 7 are provided on the inner walls of both sides of the two cable trays 10, and locking bolts 2 are provided inside both sides of the socket 1. By connecting one end of the two locking bolts 2 on the socket 1 to the two fastening seats 7 inside the cable tray 10 respectively, the socket 1 can be fixed to the wall surface.
[0033] Meanwhile, two locking bolts 2 can be placed inside the cover 5 and arranged symmetrically on the left and right. The first wire slot 4 is located at the center of the top edge of the cover 5. When the router is wall-mounted, the adapter wire 3 can be passed through the first wire slot 4 facing the top when the router is above the socket 1, and when the router is below the socket 1, the adapter wire 3 can be passed through the first wire slot 4 facing the bottom. This allows the first wire slot 4 on the cover 5 to switch back and forth between facing the bottom and facing the top.
[0034] In some examples, one end of the adapter wire 3 that passes through the first wiring slot 4 is connected to the power interface on the router or gateway. The slot is cut out inside the wall to support the installation of the gateway storage box, so that all devices in the fiber optic network except the router can be stored in the storage box and the wall surface remains aesthetically pleasing.
[0035] Meanwhile, after the two locking bolts 2 are threaded to the two fastening seats 7 inside the cable tray 10, the socket 1 can be fixed to the wall surface. In this state, one end of the adapter wire 3 passes through the inside of the first wire slot 4, which does not affect the connection between one end of the adapter wire 3 and the router.
[0036] The above design incorporates two cable management boxes 10 within the wall. One box is used for wiring the terminals on the socket 1, supporting the current flow into the socket 1. The other box is used to store the power adapter 6. When the body 11 of the right-angle female plug is connected to the contact point on the power adapter 6, and the bare wire end of the plug wire 8 is connected to the corresponding terminal, the power adapter 6 can directly receive power from the terminals inside the socket 1 through the body 11 of the right-angle female plug and the plug wire 8. This eliminates the need to plug the contact point on the power adapter 6 into the hole on the surface of the socket 1. This design achieves the aesthetic function of wall-mounting the router in the fiber optic network, preventing the power adapter and additional power strips from being scattered, thus ensuring a pleasing appearance and reducing user dissatisfaction during daily use.
[0037] Meanwhile, by passing the bolts through the interior of both sides of the cover 5 and the two fastening seats 7 inside the cable tray 10, since the first cable slot 4 is located at the center of the top of the two locking bolts 2, when the cover 5 is installed upside down, the first cable slot 4 can face the bottom. This makes it convenient to pass the adapter cable 3 through the first cable slot 4 facing the top when the router is wall-mounted above the socket 1, and through the first cable slot 4 facing the bottom when the router is below the socket 1, which is flexible and convenient.
[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
