Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sockets, and particularly relates to a German corner socket. Background Art
[0002] A socket is an important component in an electrical system and is used to provide power to various electrical devices. With the development of technology, the demand for electrical devices in home and commercial environments is increasing continuously, especially in occasions where convenient and efficient connection and disconnection of electrical appliances are required.
[0003] When traditional sockets are designed, most of them are standard straight-in sockets, and their thickness and size are not optimized according to the requirements of space utilization. In many homes and offices, due to the large size of the sockets, when multiple sockets are installed side by side, congestion will occur, resulting in insufficient space between the sockets, which in turn affects the convenience and safety of simultaneously inserting multiple electrical devices. In addition, the outer shell design of some sockets is relatively bulky, increasing the distance between the socket and the wall, thus occupying more space in a limited area.
[0004] Most current sockets adopt a vertical or horizontal plugging and unplugging method, and the plug must be inserted into the socket at a certain angle. Although this design meets the basic functions, in places with limited space or special designs (such as where the wall decoration is thin or the equipment layout is dense), plugging and unplugging the plug may become extremely inconvenient. Especially when the power plug is large in size or the connecting cable of the plug is long, the limitation of the plugging and unplugging angle will make it difficult for the device to be inserted or removed, increasing the difficulty and time of use.
[0005] In many modern home and office environments, the number of electrical devices has increased significantly, such as computers, TVs, air conditioners, kitchen appliances, etc. Therefore, traditional sockets may not meet the requirements, and users have to use multiple power strips or extension cords, which not only easily cause chaos in electrical connections but also may lead to potential electrical safety hazards. In addition, the position of the socket is often not very flexible, and the socket fixed on the wall may not meet the requirements of different angles and space layouts in some cases. The plugging and unplugging method of traditional sockets and the structural design of the socket itself may cause current impact or poor electrical contact during the plugging and unplugging process to a certain extent. Due to the incomplete coincidence of the contact surfaces of the socket and the plug or the lack of flexibility in the plugging and unplugging angle, the contact may be unstable, which in turn affects the normal operation of electrical devices and even poses a risk of fire or electrical accidents. No solutions have been proposed for the related technical problems. Content of the Utility Model
[0006] To address the problems in related technologies, this utility model proposes a German-style corner socket to overcome the aforementioned technical issues in existing technologies. The purpose of this utility model is to maximize space saving by using a corner socket with a 90-degree plug-in design, allowing for more compact placement and arrangement, thereby improving space utilization efficiency. It solves the problem that traditional sockets cannot flexibly adapt to different plug-in angles, reduces interference between sockets, and facilitates the simultaneous insertion of multiple electrical devices. It also solves the problem that traditional sockets are too tightly packed to allow multiple plugs to be inserted at the same time. This not only reduces the risk of electrical faults but also avoids safety hazards such as electrical fires caused by poor socket contact, while improving aesthetics and tidiness.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a German-style corner socket, comprising a lower cover, an upper cover on top of the lower cover, a plurality of single-break switches inside the lower cover, a USB power board on one side of each single-break switch, a double-break switch on one side of each USB power board, a grounding clamp assembly on one side of each double-break switch, a plurality of protective boxes at the bottom of each grounding clamp assembly, an L-polar conductive sheet at the bottom of each protective box, an N-polar conductive sheet at the bottom of each L-polar conductive sheet, a hanging hole cover plate at the bottom of each N-polar conductive sheet, and a power cord connected to one side of the lower cover via a cable protector.
[0008] Preferably, the grounding clamp assembly is made of metal material, and the grounding clamp assembly includes a grounding clamp and a grounding terminal. Several grounding clamps are provided, and all of them are disposed on the grounding terminal.
[0009] Preferably, the upper cover has a single-break switch hole, a double-break switch hole, and a USB power port.
[0010] Preferably, the lower cover and the upper cover are made of plastic material.
[0011] Preferably, the upper cover is also provided with heat dissipation holes.
[0012] Preferably, the lower cover has an L-shaped cross-section.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model is a German-style corner socket. The corner socket with a 90-degree plug-in design makes the socket no longer occupy too much space during the insertion and removal process, maximizing space saving and allowing for more compact placement and arrangement, thereby improving the efficiency of space use. It solves the problem that traditional sockets cannot flexibly adapt to different plug-in angles. Users can more easily insert or remove plugs from the socket, avoiding the inconvenience caused by the unsmooth insertion and removal of traditional sockets. Especially for large appliances or devices with long plugs, the insertion and removal operations can be completed more smoothly.
[0015] (2) This utility model is a German-style corner socket that does not occupy too much space. Multiple sockets can be installed more closely side by side, which not only reduces interference between sockets, but also makes it convenient to insert multiple electrical devices at the same time. It solves the problem that traditional sockets cannot insert multiple plugs at the same time because they are too close together. In the 90-degree plug-in design, the contact surface of the socket and the plug make a tighter contact, avoiding poor contact problems that may occur during plugging and unplugging. This not only reduces the risk of electrical faults, but also avoids safety hazards such as electrical fires caused by poor socket contact; it reduces the size and protruding parts of traditional sockets, allowing them to better integrate into the wall and making the socket look simpler and neater. This not only improves the overall aesthetics, but also avoids the sense of disharmony caused by the size and shell of traditional sockets. Attached Figure Description
