Description
Technical Field
[0001] The utility model relates to the technical field of a solid-sealed upper outlet seat, in particular to a split three-phase solid-sealed upper outlet seat. Background Art
[0002] The emergence of the sealed upper outlet seat is to solve the need for cable connection in the power system. It is designed to provide a convenient, safe and reliable connection method, reducing the difficulty of installing and replacing cables or wires. Behind this device is the continuous pursuit of power system safety and efficiency. It ensures the stability and reliability of cable connections and helps to ensure the operation of the entire power system. These sealed upper outlet seats are usually manufactured according to certain standards to ensure their quality, reliability and safety. Its design and use specifications are adjusted according to different power system needs and industry standards to meet specific application and environmental requirements. The working principle of the sealed upper outlet seat is based on its internal construction and material selection. It is usually made of metal materials with good electrical conductivity, such as copper or aluminum alloy. When the cable or wire is inserted into the sealed upper outlet seat, its end contacts the sealed pole or conductive part to form an electrical connection. This design ensures that the current can be transmitted from the cable to the power system, realizing the connectivity of the circuit. Its core function is to serve as a connection point so that the cable or wire can be easily and safely connected to the power system. This connection is a key link in power transmission because it allows electrical energy to be transmitted between equipment, systems or different power nodes. The design of this socket helps ensure the strength and stability of the electrical connection, thereby effectively transmitting current and ensuring the operation of the power system.
[0003] A clockwork hinge is a mechanical device that is mainly used to control the opening and closing of a door, lid or other object. It uses a clockwork or spring that stores energy and drives the movement of the door or lid when the energy is released, so that it opens or closes automatically. This hinge design helps to reduce the burden of user operation and to a certain extent control the opening speed and closing force of the door or lid. The principle of a clockwork hinge is based on a clockwork or spring that stores energy. When the door or lid is closed, the spring or clockwork is compressed or stretched, storing energy. When the door or lid needs to be opened, the energy of the spring or clockwork is released, driving the door or lid to open automatically. In some clockwork hinges, the clockwork can be re-installed manually or mechanically to prepare for the next opening.
[0004] Traditional sealed upper outlet sockets and sealed poles are usually formed in one piece. This integrated design, while ensuring the reliability of electrical connections, also brings some challenges. For example, when the sealed upper outlet socket is damaged, the damaged part cannot be directly replaced alone, but the entire electrical component needs to be replaced. This not only increases the difficulty of maintenance, but also brings significant repair costs; in addition, due to the limitations of the integrated design, when cables of different sizes need to be inserted into the sealed upper outlet socket, outlet sockets of different models usually need to be replaced. This means that in order to adapt to cables of different sizes, multiple sizes or models of upper outlet sockets are required. This increases the complexity of storing and managing outlet sockets of different specifications, and also increases the cost and workload of maintenance and management. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1 , this figure is a schematic diagram of the structure in which a limit assembly 2 is arranged in the upper outlet seat body 1, and a rubber protective sleeve is arranged on the outer periphery of the upper outlet seat body 1; at least two limit assemblies 2 are cleverly arranged on the inner ring of the head of the upper outlet seat body 1. In the schematic diagram, four limit assemblies 2 are arranged, which is to produce a more balanced pressure distribution on the inserted cable. By increasing the number of limit assemblies 2, the pressure at the insertion point can be better dispersed, thereby providing more uniform support and enhancing the fixing effect on the cable. This design of multiple limit assemblies 2 ensures that when the cable is inserted, each limit assembly 2 works together to form a balanced supporting force and avoid excessive pressure at a single point. Such a design optimizes the contact between the cable and the limit assembly 2, ensuring a more firm and reliable connection; the structure shown in the figure not only improves the stability near the insertion point, but also enhances the support and fixing effect of the entire upper outlet seat on the cable, providing an important guarantee for the reliable operation of the power system.
[0026] See also Figure 2 The limiting component 2 is in the shape of a hexagonal column, and the bottom surface is a bottom plate 21 that fits the upper outlet seat body 1. The bottom plate 21 is welded or bonded to the inner wall of the upper outlet seat 1. A first spring hinge 22 is arranged around the bottom plate 21. A pressure plate 23 is hinged on the first spring hinge 22. The pressure plate 23 is an arc-shaped straight plate that fits the inner wall of the upper outlet seat body 1. The arc-shaped straight plate design of the pressure plate 23 ensures a perfect fit with the inner wall of the upper outlet seat body 1, and enhances the firmness of the support. The upper side of the pressure plate 23 is provided with a second The spring hinge is hinged with a connecting plate 24, and the upper side of the connecting plate 24 is hinged with a supporting plate 25 through a third spring hinge. The supporting plate 25 forms the top plate of the limiting assembly 2, which enables the cable to move in a coordinated manner when inserted into the area enclosed by each limiting assembly 2. At the same time, through the ingenious combination of the spring hinges, the limiting assembly 2 can achieve multi-directional movement, providing more stable and balanced support for cable insertion, ensuring the efficiency and reliability of the cable connection process in the sealed upper outlet seat.
[0027] See also Figure 3-4 The limit assembly 2 is pressed against the inside of the upper outlet seat body 1 to form a tight fit; when the support plate 25 of the limit assembly 2 is subjected to pressure, it will move toward the bottom plate 21, forming an adaptive support mechanism, and will return to its original state when the pressure disappears, that is, Figure 4 As shown, when the cable is inserted, each support plate 25 is pressed and moves toward the bottom plate 21. Since the spring hinge is deformed under pressure, energy is stored. The release of this energy generates a squeezing force on the cable, thereby fixing the cable.
[0028] See also Figure 5 A thread 11 is designed on the inner side of the tail of the upper outlet seat body 1 to be threadedly connected to the sealed pole. The thread 11 is used to connect to the sealed pole. This split design makes the equipment easier to maintain. There is a rubber ring at the tail of the upper outlet seat body 1. When the upper outlet seat body 1 is threadedly connected to the sealed pole, the rubber ring provides sealing and tightness between the two.
[0029] Working principle: First, at least two limit assemblies are set on the inner ring of the head of the upper outlet seat body. These hexagonal limit assemblies fit perfectly with the bottom plate, ensuring good cooperation between the limit assemblies and the inner wall of the upper outlet seat body when in the connected state; during the entire connection process, the support plate of the limit assembly will move toward the bottom plate when under pressure. This design enables the support plates of each top plate to adjust their positions according to the external pressure when the cable is inserted, forming a uniform support force, which effectively increases the stability and firmness of the cable insertion point; when the cable is inserted, the spring hinge of the limit assembly is deformed under pressure, storing the energy of elastic potential energy. This stored energy is released at the right time, exerting a squeezing force on the cable and firmly fixing the cable in place.
[0030] In summary, the split three-phase solid-sealed upper outlet seat is designed with at least two limit components 2 arranged around the inner side of the head of the upper outlet seat body 1, and the hexagonal columnar limit component 2 is perfectly combined with the bottom plate 21 of the upper outlet seat body 1, and the first spring hinge 22, pressure plate 23, connecting plate 24, and support plate 25 cleverly arranged around the bottom plate 21 form the top plate of the limit component 2, providing a highly stable channel for cable insertion; when the cable is inserted into the channel surrounded by the limit component 2, the support plate 25 is pressed and moves toward the bottom plate 21, and this design enables the cable size within a certain range to be adapted to this upper outlet seat body 1; at the same time, due to the deformation of the limit component 1, the energy of all the spring hinges will be stored, and the stored energy will be applied to the cable when released, so that it is firmly fixed, thereby achieving the effect of being able to flexibly adapt to cables of different sizes. In addition, the threaded connection between the upper outlet seat body 1 and the solid-sealed pole adopts a split design, which provides a feasible solution for reducing maintenance costs. During maintenance or replacement, the damaged part can be replaced individually without replacing the entire device, which brings significant convenience to maintenance and management, thereby achieving the effect of reducing maintenance costs by split type.
