Description

Technical Field

[0001] This application relates to the field of circuit breakers, and more specifically, to a socket structure for a circuit breaker switch. Background Technology

[0002] Switches, sockets, and other connecting components in circuit breakers serve to facilitate the insertion and removal of current and connect the internal and external circuits of the circuit breaker. They are widely used in industrial and mining power distribution systems requiring frequent switching, motor control systems, and other fields requiring flexible expansion or rapid switching, such as the Internet of Things and data centers. The quality of the switches and sockets in circuit breakers directly affects the reliability and stability of the circuit breaker and the power control system.

[0003] Most existing switches and sockets are fastened together using five parts: a socket head with threaded holes at the ends, a nut, a spring washer, a flat washer, and a conductive component with a threaded rod structure. When circuit breakers using this type of switch and socket are applied in high-frequency vibration environments such as subways, light rails, and vehicle power supply systems, the large number of parts in the switch and socket can lead to loosening over time. When peak current passes through these switches and sockets, poor contact can generate significant heat and easily burn out the switch and socket, thus affecting the reliability and service life of electrical appliances such as circuit breakers.

[0004] A search revealed limited research and reports both domestically and internationally on sockets for circuit breaker switches. Patent CN201717414U employs an interference fit between a copper alloy shell and an aluminum alloy inner core to create a plug-and-pin product. While this significantly reduces production costs, the copper-aluminum contact is physical, potentially trapping tiny air particles at the interface, posing a risk of electrochemical corrosion. Patent CN223007134U uses a rolling forming method for socket pins. Although this reduces the number of parts, the pins are prone to softening and deformation under high current impact, reducing the reliability of the switch and socket. Furthermore, it requires high processing precision and has a low yield, hindering mass production.

[0005] Therefore, it is necessary to develop a socket for equipment circuit breaker switches that is highly robust, highly reliable, and mass-producible. Summary of the Invention

[0006] In view of one of the defects in the prior art, the purpose of this application is to provide a socket structure for a circuit breaker switch.

[0007] This application provides a socket structure for a circuit breaker switch, comprising: The socket head includes a ball end, a retaining spring section, a hexagonal locking section, and a threaded fixing end, which are arranged sequentially and integrally formed; A hexagonal locking component has a through hole in its center. The threaded fixing end passes through the through hole, and the hexagonal locking section cooperates with the through hole to fasten the hexagonal locking component to the socket head. A conductive base has a flange at one end, and a flange through hole is provided on the flange, which is threadedly connected to the threaded fixing end.

[0008] Optionally, the snap ring segment has a circular or polygonal columnar structure.

[0009] Optionally, the hexagonal locking section has a circular or polygonal columnar structure.

[0010] Optionally, the cross-sectional dimension of the hexagonal locking section is smaller than the cross-sectional dimension of the snap ring section.

[0011] Optionally, the fitting clearance between the hexagonal locking member and the hexagonal locking section is -0.01mm to 0mm.

[0012] Optionally, it also includes a reverse riveting fixing structure, which is formed by reverse riveting the tail of the threaded fixing end extending from the flanged through hole.

[0013] Optionally, the height of the flange is 50% to 150% of the thickness of the conductive base.

[0014] Optionally, the outer wall of the threaded fixing end is provided with threads, and the inner wall of the flanged through hole is tapped to form a threaded inner wall that mates with the threads.

[0017] The socket structure for circuit breaker switches provided in this application adopts a socket head, a hexagonal locking component, and a conductive base. The original threaded rod and plug socket are processed into an integrated part and assembled into a plug structure containing three parts through a hexagonal hole tight fit. Compared with the existing socket head structure containing five parts, the structure is simpler, the number of parts is greatly reduced, and the variables required to prevent the socket structure from loosening are also reduced, which reduces the probability of the socket structure aging and loosening, thereby improving the connection firmness and reliability of the parts; it can also shorten the parts processing flow, reduce material waste, and facilitate mass production.

[0018] Other technical effects resulting from the additional features will be further illustrated in the corresponding embodiments. Attached Figure Description

Detailed Implementation

[0020] The present application will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present application, but do not limit the present application in any way. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present application, and these all fall within the protection scope of the present application. Parts not described in detail in the following embodiments can be implemented using existing technology.

[0021] Currently, circuit breakers contain a large number of switch and socket components, which hinders mass production and results in deficiencies in robustness and reliability. To address these issues, this application provides a socket structure for circuit breaker switches to solve these problems.

[0022] Reference Figure 1 and Figure 2 As shown in one embodiment of this application, the socket structure for the circuit breaker switch includes a socket head 1, a hexagonal locking member 2, and a conductive base 3. The socket head 1 includes a ball end 4, a snap ring section 5, a hexagonal locking section 6, and a threaded fixing end 7, which are sequentially arranged and integrally formed. The hexagonal locking member 2 has a through hole 8 at its center, and the threaded fixing end 7 passes through the through hole 8. The hexagonal locking section 6 cooperates with the through hole 8 to fasten the hexagonal locking member 2 to the socket head 1. One end of the conductive base 3 has a flange, and the flange has a flanged through hole 9, which is threadedly connected to the threaded fixing end 7.

[0023] Specifically, the ball end 4, the snap ring section 5, the hexagonal locking section 6, and the threaded fixing end 7 together form the overall geometric structure of the socket head 1. The ball end 4 is a spherical structure located at one end of the socket head 1, the threaded fixing end 7 is located at the other end of the socket head 1, and the snap ring section 5 is located between the ball end 4 and the hexagonal locking section 6. This embodiment breaks through the conventional design concept of existing products. The threaded fixing end 7 can be regarded as a threaded rod in existing conventional products. By adjusting the structure, the threaded rod and the plug socket are processed into an integrated part to replace the existing threaded, nut, and washer connection method of switch sockets, saving the number of parts and making it more conducive to mass production. The outer wall of the hexagonal locking part 2 has a hexagonal geometric structure, which facilitates the clamping of the hexagonal locking part with tooling when installing the hexagonal locking part and the socket head, and keeps the axes of the two parts aligned during installation.

[0024] The hexagonal locking section 6, the snap ring section 5, and the threaded fixing end 7 have the same axis of symmetry, making the overall structure of the socket head 1 columnar. The different geometric structures are only present at different positions of the socket head parts to achieve different functions. The cross-sectional shape of the through hole 8 of the hexagonal locking part 2 is consistent with the cross-sectional shape of the hexagonal locking section 6 of the socket head 1, which makes it easy for the hexagonal locking part 2 to be fitted into the hexagonal locking section 6 of the socket head 1. The through hole 8 of the hexagonal locking part 2 and the hexagonal outer wall structure of the hexagonal locking part 2 have the same axis of symmetry, which allows the tooling fixture to hold the hexagonal locking part 2 well when installing it.

[0025] In the above embodiments of this application, a socket head 1, a hexagonal locking component 2, and a conductive base 3 are used to process the original threaded rod and plug socket into an integrated part. The plug structure containing three parts is assembled by a tight fit through the through hole (hexagonal hole or round hole) of the hexagonal locking component. Compared with the existing socket head structure containing five parts, the structure is simpler, the number of parts is greatly reduced, and the variables required to prevent the socket structure from loosening are also reduced, which reduces the probability of the socket structure aging and loosening, thereby improving the connection firmness and reliability of the parts. It can also shorten the parts processing flow, reduce material waste, and facilitate mass production.

[0026] In some specific embodiments of this application, the retaining ring section 5 has a circular or polygonal columnar structure. The hexagonal locking section 6 has a circular or polygonal columnar structure.

[0027] Specifically, the hexagonal locking section uses a round hole structure, which makes it easier to assemble the hexagonal locking component. The polygonal columnar structure helps to restrict the axial rotation of the hexagonal locking component. The appropriate structure can be selected based on the dimensions and mechanical properties of the parts.

[0028] In order to improve the connection between the socket head 1 and the hexagonal locking member 2, in some specific embodiments of this application, the cross-sectional dimension of the hexagonal locking section 6 is smaller than the cross-sectional dimension of the snap ring section 5.

[0029] In the above embodiments of this application, the cross-sectional dimension of the hexagonal locking section 6 is smaller than that of the snap ring section 5, forming a step on the side wall of the socket head 1, which facilitates the subsequent assembly of the hexagonal locking component 2 and restricts the installation position of the hexagonal locking component 2.

[0030] To further improve the reliability of the socket, in some specific embodiments of this application, the fitting gap between the hexagonal locking member 2 and the hexagonal locking section 6 is -0.01mm to 0mm.

[0031] In the above embodiments of this application, the hexagonal locking member 2 is tightly fitted with the hexagonal locking section 6 of the socket head 1, thereby restricting the subsequent movement of the spring on the outer wall of the socket head retaining spring section 5, so that the spring maintains its elasticity, and thus the circuit breaker of the equipment made using the switch socket has the function of preventing it from loosening and falling off the circuit when plugged in and out.

[0032] In order to improve the connection strength between the socket head 1 and the conductive base 3, in some specific embodiments of this application, the outer wall of the threaded fixing end 7 is provided with threads, and the inner wall of the flanged through hole 9 is tapped to form a threaded inner wall that mates with the threads.

[0033] Specifically, the outer wall of the other end of the socket head 1 is threaded to form a threaded fixing end 7; the inner wall of the flanged through hole 9 of the conductive seat 3 is tapped to form a threaded inner wall, which matches the threaded end of the socket head 1 to achieve a good threaded fastening connection.

[0034] In the above embodiments of this application, by adding a flanged through hole 9 to the conductive base 3 and tapping the hole, the connection strength between the conductive base 3 and the screw thread fixing end 7 of the plug seat is increased.

[0035] To further improve the firmness and reliability of the connection between the various parts, in some specific embodiments of this application, the socket structure also includes a reverse riveting fixing structure 11, which reverse rivets the tail of the thread fixing end 7 of the outwardly extending flanged through hole 9 to form the reverse riveting fixing structure 11.

[0036] Specifically, the conductive base 3 is threaded and connected to the threaded fixing end 7 of the socket head 1 by means of thread fastening. Then, the tail of the threaded fixing end 7 of the socket head with the flanged through hole 9 extending outward is riveted in the opposite direction to form a reverse riveting fixing structure 11. The socket head 1 is pre-connected with a hexagonal locking member 2 before riveting.

[0037] The embodiments described above in this application further improve the firmness and reliability of the connections between the various parts of the switch and socket through reverse riveting. When a large current flows through the switch and socket, because the parts of the socket do not loosen, the materials are less likely to experience poor contact, high contact thermal resistance, and thus problems such as high-temperature softening and burning.

[0038] In order to simultaneously meet the requirements of connection strength and ease of processing, in some specific embodiments of this application, the height of the flange is 50% to 150% of the thickness of the conductive base 3.

[0039] In the above embodiments of this application, by setting the height of the flange, the threaded hole channel of the conductive seat 3 is long enough, while ensuring the yield of the flange processing.

[0040] Considering that the socket may be in a high-temperature and high-humidity working environment, in some specific embodiments of this application, the socket head 1 and the hexagonal locking member 2 are made of any one of the following: brass plated with silver, iron plated with copper and then plated with silver, copper alloy plated with silver, copper plated with silver, copper, and copper alloy. The conductive base 3 is made of any one of the following: iron plated with copper and then plated with silver, copper plated with silver, copper alloy plated with silver, copper, and copper alloy.

[0041] For example, the copper plating layer thickness is 3μm to 6μm, and the silver plating layer thickness is 1μm to 10μm.

[0042] In the embodiments described above, each component of the switch and socket has rust-proof function, which can be applied to special applications such as high temperature and high humidity, thus improving its applicability.

[0043] The circuit breaker switch socket structure provided in the above embodiments of this application, through structural adjustment, integrates the original threaded rod and plug socket into a single part, replacing the existing threaded, nut, and washer connection method of switch sockets, resulting in a simpler structure. The plug socket assembly, consisting of 3 parts, is assembled using a hexagonal hole tight-fitting method, replacing the existing socket head structure with 5 parts. This significantly reduces the number of parts, shortens the parts processing flow, reduces material waste, and facilitates mass production, high quality, and cost-effectiveness. Furthermore, the reduction in the number of parts also reduces the variables required to prevent socket structure loosening, thereby lowering the probability of socket structure aging and loosening, and improving product performance.

[0044] When a large current flows through the switch and socket provided in the above embodiments of this application, the material is less likely to experience high-temperature softening or burning due to poor contact, thereby improving the quality, reliability, and stability of electrical products such as circuit breakers.

[0045] The socket structure described in the above embodiments of this application breaks through the conventional design concept of existing products. It significantly reduces the number of parts, simplifies the structure, and facilitates mass production. It effectively solves problems such as numerous parts, poor vibration resistance, and susceptibility to aging, loosening, overheating, and burning in existing switch and socket structures. It shortens the parts processing flow, reduces material waste, and significantly reduces the production cost of sockets for circuit breaker switches for enterprises. Compared to the existing conventional 5-part socket structure, the circuit breaker obtained using the socket described in the above embodiments of this application has a 21% increase in production efficiency and a 16% increase in mechanical life.

[0046] It should be understood that the types of materials, number of layers, thickness, processing methods, and application fields of the switch and socket components involved in the above embodiments can all be adjusted within the scope of this application. This is easily achieved by those skilled in the art based on the description in this application, and therefore will not be elaborated further.
