Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power sockets, specifically relating to a safety socket terminal block. Background Technology
[0002] Power sockets are essential power supply devices for daily electricity use. Their main function is to provide terminals for electrical equipment to connect to the power supply line. The circuit for electrical equipment connects to the live wire and the neutral wire to supply power. In a power socket, the live wire terminal and the neutral wire terminal are essential components. When the plug of an electrical device is inserted into the power socket, the metal prongs of the plug connect to the live wire terminal and the neutral wire terminal respectively, thus establishing a circuit. However, this traditional socket has a drawback: if the power to an electrical device is left on and the plug is not fully inserted or removed from the socket, the contact between the plug prongs and the live and neutral wire terminals can create a conductive circuit, potentially leading to a short circuit. Accidental contact with the socket in this situation could result in electric shock and a safety hazard. Therefore, it is necessary to improve the wiring terminals of the socket to enhance its safety. Utility Model Content

The switch spring is located between the insertion slot and the stationary conductive block, and the stationary conductive block is located at the end of the moving path of the movable conductive block.
[0006] Preferably, the conductive socket is formed by bending a metal conductive sheet, and the metal conductive sheets on both sides of the insertion groove are folded outwards to form two inclined guide surfaces on the front side of the insertion groove.

[0015] The beneficial effects of this utility model are as follows:
[0016] This utility model discloses a safety socket terminal block, which can be used as the live wire terminal and / or neutral wire terminal of the socket. It has a simple structure, is easy to manufacture, and has low production cost. The insertion groove of the conductive sleeve is used to connect with the prongs of the plug.

Therefore, the safety of the socket can be greatly improved. Attached Figure Description

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., 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.
[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] refer to Figures 1-4 This application claims protection for a safety socket terminal block, which is mainly used as a live wire connection terminal and / or neutral wire connection terminal and / or ground wire connection terminal of the socket. The safety socket terminal block includes a conductive sleeve 1, a stationary conductive block 2, and a moving conductive block 3. The insertion groove 11 of the conductive sleeve 1 is used to connect with the pins of a plug. The stationary conductive block 2 and the moving conductive block 3 are spaced apart, so that even if the socket is connected to a power source, the socket cannot supply power because the moving conductive block 3 is not connected to the stationary conductive block 2.
[0025] In detail, the movable conductive block 3 is installed on the movable end of the switch spring 12, and the other end of the switch spring 12 is a fixed end. Under the action of force, the movable end of the switch spring 12 can rotate with the fixed end as a fulcrum, thereby driving the movable conductive block 3 to move. The insertion groove 11 is a through groove. The movable end of the switch spring 12 extends to one side of the insertion groove 11 of the conductive sleeve 1, and the body of the switch spring 12 is perpendicular to the groove direction of the insertion groove 11 of the conductive sleeve 1. The switch spring 12 is located between the insertion groove 11 and the stationary conductive block 2. The stationary conductive block 2 is located at the end of the moving path of the movable conductive block 3. When the plug pins are inserted into the socket 11, the movable end of the switch spring 12 blocks the upward movement of the socket 11, allowing the plug pins to contact the movable end of the switch spring 12. This provides a pushing force to the movable end of the switch spring 12, enabling it to move the movable conductive block 3. When the plug pins are fully inserted into the socket 11, the movable conductive block 3 moves to the end of its path and contacts the stationary conductive block 2. At this time, the circuit in the socket is connected, providing power to the plug. If the plug pins are not fully inserted into the socket 11, the movable conductive block 3 does not move to the end of its path, and the stationary conductive block 2 does not contact the movable conductive block 3. In this case, the circuit in the socket is disconnected, and the socket remains de-energized.
[0026] In other embodiments, the conductive sleeve 1 can be formed by welding multiple metal conductive sheets, with at least two sides of the insertion groove 11 being metal conductive sheets. When the plug pins are inserted into the insertion groove 11, they can contact the metal conductive sheets on both sides of the insertion groove 11. Furthermore, to reduce production costs, improve production efficiency, and address the problem of complex structures in traditional conductive sleeves, in this application, the conductive sleeve 1 is formed by bending a single metal conductive sheet. The metal conductive sheets on both sides of the insertion groove 11 are folded outwards, forming two inclined guide surfaces on the front side of the insertion groove 11. When the terminal block is installed inside the socket housing, the guide surfaces are located inside the socket hole of the socket housing, and the insertion groove 11 is aligned with the socket hole, which facilitates the precise insertion of the plug pins into the insertion groove 11.
[0027] To ensure that the conductive sleeve 1 can be stably installed inside the socket housing, the outer sides of the metal conductive sheets on both sides of the insertion groove 11 are respectively provided with bearing surfaces 13. The bearing surfaces 13 are located on the side of the metal conductive sheet away from the guide plate. The bearing surfaces 13 can be welded to the outer side of the metal conductive sheet, or they can be formed by folding the rear side of the metal conductive sheet outward. Preferably, the bearing surfaces 13 match the support surface of the socket housing, and are used to vertically install the insertion groove 11 inside the socket housing. In this embodiment, the bearing surfaces 13 are horizontal. In other embodiments, the bearing surfaces 13 can also be inclined or curved.
[0028] In detail, in this embodiment, the conductive sleeve 1 includes a conductive frame 14 connecting the insertion slot 11. The conductive frame 14 has an L-shaped structure, and the switch spring 12 is connected to the end of the conductive frame 14, so that there is a distance difference between the insertion slot 11 and the switch spring 12. The end face of the conductive frame 14 is perpendicular to the body of the switch spring 12, and the switch spring 12 can improve the installation stability of the conductive frame 14. It is worth noting that the switch spring 12 can be welded to the bottom of the conductive frame 14, or it can be integrally formed with the conductive sleeve 1. As a preferred embodiment, the switch spring 12 and the conductive sleeve 1 are formed by bending the same piece of metal conductive sheet.
[0029] To improve the compatibility between the socket 11 and the plug pins, the conductive sleeve 1 includes a tension buffer groove 15 communicating with the socket 11. The tension buffer groove 15 is formed by bending the metal conductive sheet. The tension buffer groove 15 allows the metal conductive sheets on both sides of the socket 11 to have good elastic tension. Therefore, the width of the socket 11 can be finely adjusted according to the plug pins. When the plug pins are inserted into the socket 11, the metal conductive sheets on both sides of the socket 11 can move outward, increasing the width of the socket 11. The metal conductive sheets can elastically press tightly against one side of the plug pins. When the plug pins are pulled out of the socket 11, the metal conductive sheets on both sides of the socket 11 return to their original position under elastic action.
[0030] Furthermore, the switch spring 12 includes a movable end and a fixed end. The fixed end is connected to the bottom of the conductive frame 14. The angle between the movable end and the fixed end is an obtuse angle. The switch spring 12 is stamped from a metal conductive sheet. The fixed end and the movable end are integrally formed. The movable end includes a slanted pressure plate 16. The end of the slanted pressure plate 16 near the fixed end is folded downwards and connected to the slanted pressure plate 16. The movable conductive block 3 is installed at the end of the slanted pressure plate 16 away from the fixed end. The folding angle of the slanted pressure plate 16 is greater than 120°. The plug pins are inserted and pass through the plug slot 11, abutting against the upper end of the slanted pressure plate 16. By applying pressure to the slanted pressure plate 16, the slanted pressure plate 16 is elastically pressed down, thereby causing the movable conductive block 3 to press down synchronously, ultimately achieving contact with the stationary conductive block 2 and connecting the circuit. The static conductive block 2 is mounted on the metal conductive frame 21. The structure of the metal conductive frame 21 matches the mounting groove on the socket shell. In this embodiment, the metal conductive frame 21 includes a static conductive block mounting surface. The static conductive block mounting surface is connected to an inverted L-shaped connecting frame. The metal conductive frame 21 is mounted on the socket shell through the inverted L-shaped connecting frame, so that the static conductive block 2 is stably installed inside the socket shell.
[0031] In summary, the safety socket terminal disclosed in this utility model can be used as the live wire terminal and / or neutral wire terminal of the socket. It has a simple structure, is easy to manufacture, and has low production cost. The insertion groove of the conductive sleeve is used to connect with the prongs of the plug. When the plug is not fully inserted into the socket, the socket will not be energized because the stationary conductive block and the moving conductive block are not in contact. Only when the prongs of the plug are fully inserted into the insertion groove will the prongs of the plug push the moving conductive block of the switch spring to the side of the stationary conductive block, so that the moving conductive block and the stationary conductive block come into contact, thereby enabling the socket to be energized. Therefore, the safety of the socket can be greatly improved.
[0032] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the utility model. It should not be construed that the specific implementation of the utility model is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the inventive concept, and all such modifications and substitutions should be considered within the scope of protection of the utility model.
