Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of modular socket components, specifically a modular socket component. Background Technology
[0002] In modern power systems, surges and overloads are major causes of equipment damage and power accidents. To ensure the safe operation of electrical equipment, surge protectors and fuses are widely used in power systems. Surge protectors suppress overvoltage events, while fuses disconnect circuits by melting to prevent overloads or short circuits from causing fires and other safety accidents. As users' requirements for electrical equipment safety increase, socket assemblies integrating surge protectors or fuses are gradually becoming an important component of power protection systems. Currently, by using pluggable surge protectors and fuses with sockets that house protection modules, damaged surge protectors and fuses can be replaced simply by replacing the modules without disconnecting the circuit, making the process simple and efficient.
[0003] Existing pluggable sockets can be broadly categorized into two types: integrated and modular. Integrated sockets offer a more complete overall structure, with better appearance and structural strength. However, they require the development of corresponding bases for each pole, resulting in low repeatability and high cost (due to low component versatility and high cost). Modular sockets, on the other hand, typically develop only single-pole bases, mechanically assembling them to form multi-pole bases. This leads to large gaps between poles, poor overall integrity, and the need for external busbars to connect the poles, resulting in complex use and an unattractive appearance. Therefore, it is necessary to provide a modular socket assembly that offers tight and convenient splicing, good overall integrity, and meets the safety, stability, and economic requirements of modern power systems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a modular socket assembly that solves problems such as complex splicing structures, loose splicing, and poor overall splicing integrity in some existing socket assemblies.
[0005] A modular socket assembly includes a first socket, a second socket, and a third socket. The first socket has a first annular protrusion on one side and a plurality of positioning posts in the center. The second socket has a second annular protrusion on one side and a plurality of limiting posts in the center. The third socket has two opposite sides, each including a first annular protrusion on one side and a plurality of positioning posts in the center, and a second annular protrusion on the other side and a plurality of limiting posts in the center. Each positioning post has an inwardly recessed positioning hole on its outer side wall for insertion of the limiting post. The first annular protrusion has a receiving space recessed from the side away from the first or third socket towards the side closer to the first or third socket. The inner side wall of the receiving space has an annular groove recessed towards its outer side wall. The outer side wall of the second annular protrusion has an annular receiving groove towards its inner side wall. An annular rubber ring is embedded in the annular receiving groove. When the modular socket assembly is assembled, the annular rubber ring is tightened at the annular groove.
[0006] Preferably, the first socket, the second socket, and the third socket all have a threaded hole on each side along their length that is opposite to each other when they are joined together.
[0007] Preferably, each of the first socket, the second socket, and the third socket has a mounting hole at both ends of its bottom along the length direction. When the modular socket assembly is assembled, the mounting holes in the first socket, the second socket, and the third socket are interconnected, and a busbar is provided in the assembled mounting hole.
[0008] Furthermore, the busbar is an integral busbar, which is formed by processing an integral metal sheet. The bottom of the busbar forms a U-shaped structure, and a plug-in structure is formed between the U-shaped structures. The plug-in structure is provided with a first plug-in hole corresponding to the top of the modular socket assembly. The plug-in structure is used to contact the pins of the surge protector or fuse, and the plug-in structure is elastic to hold the pins.
[0009] Preferably, the cross-sections of the first socket, the second socket, and the third socket are all U-shaped.
[0010] Preferably, the first socket, the second socket, and the third socket are provided with limit baffles on the two opposite inner surfaces that come into contact with the surge protector or fuse when they are plugged in. After the modular socket assembly is assembled, the gap between two adjacent limit baffles is slightly greater than or equal to the width of the surge protector or fuse.
[0011] Preferably, an L-shaped notch is provided on one bottom side of the first socket along its length and on one bottom side of the third socket along its length, and an L-shaped plate is provided on one bottom side of the second socket along its length and on the other bottom side of the third socket along its length, which is offset from the L-shaped notch. When the modular socket assembly is assembled, the L-shaped notch and the L-shaped plate are spliced and fastened together.
[0012] Preferably, each of the three inner surfaces of the first, second, and third sockets that come into contact with the surge protector or fuse is provided with a heat sink. Each heat sink has a heat dissipation fin on the side away from the surge protector. The heat sinks are all located in the mounting slots provided in the first, second, and third sockets.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This utility model provides a modular socket assembly. Firstly, by designing multiple positioning and limiting posts on the sides of the first, second, and third sockets, the limiting posts can be inserted into the positioning posts during connection, thus achieving alignment and facilitating subsequent connection. Next, as the two bases to be joined approach each other, a second annular protrusion inserts into the receiving space of the first annular protrusion. Then, as they continue to approach, the annular rubber ring on the second annular protrusion engages with and tightens within the annular groove. At this point, the two bases are tightly connected through the annular rubber ring tightening within the annular groove. Simultaneously, the first annular protrusion being a single ring enhances the sealing between the sockets after the modular socket assembly is assembled, effectively preventing the intrusion of external contaminants such as dust and moisture, and avoiding the risk of electrical equipment malfunction or electrical accidents due to poor external environments. Furthermore, the modular design of the modular socket assembly allows for free combination and replacement of sockets according to needs, simplifying the installation and maintenance process. Users can easily replace damaged modules or adjust socket positions, greatly improving operational convenience. Finally, through modular design, the socket components can be highly interchangeable, reducing production and procurement costs while improving product economy and production efficiency. Therefore, the modular socket assembly of this invention has significant advantages in structural design, ease of installation, safety, and economy, and can meet the multiple requirements of modern power systems for socket assemblies that are efficient, safe, and aesthetically pleasing.

Detailed Implementation
[0020] The embodiments described below are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0021] See Figures 1-3 This embodiment provides a modular socket assembly, which includes a first socket 10, a second socket 20, and a third socket 30. The first socket 10 has a first annular protrusion 21 and a plurality of positioning posts 22 disposed in the center on one side of its outer periphery. The second socket 20 has a second annular protrusion 31 and a plurality of limiting posts 32 disposed in the center on one side of its outer periphery. The third socket 30 has two opposite sides, each including a first annular protrusion 21 and a plurality of positioning posts 22 disposed in the center on one side, and a second annular protrusion 31 and a plurality of limiting posts 32 disposed in the center on the other side. The outer side wall of the positioning post 22 is recessed inward to form a positioning hole 23, which is used for the insertion of the limiting post 32. The first annular protrusion 21 is recessed inward from the side away from the first socket 10 or the third socket 30 to the side closer to the first socket 10 or the third socket 30 to form a receiving space 24. The inner side wall of the receiving space 24 is recessed inward to the side of the outer side wall to form an annular groove 25. The outer side wall of the second annular protrusion 31 is provided with an annular receiving groove 33 inward to the side of the inner side wall. An annular rubber ring 34 is embedded in the annular receiving groove 33. When the modular socket assembly is assembled, the annular rubber ring 34 is tightened at the annular groove 25.
[0022] It should be noted that when assembling the modular socket assembly in this embodiment, one first socket 10, one second socket 20, and zero or more third sockets 30 are selected. The number of third sockets 30 can be selected and assembled according to the requirements.
[0023] Preferably, the first socket 10, the second socket 20, and the third socket 30 all have a threaded hole 40 on both sides along their length for splicing. Screws are screwed into the threaded holes 40 to ensure a tighter, more seamless connection between the sockets, further reinforcing the tight connection.
[0024] Preferably, each of the first socket 10, the second socket 20, and the third socket 30 has a mounting hole at both ends of its bottom along its length. When the modular socket assembly is assembled, the mounting holes in the first socket 10, the second socket 20, and the third socket 30 are interconnected, and a busbar is provided in the assembled mounting holes. Further, the busbar is an integral busbar, formed from a single piece of metal. The bottom of the busbar forms a U-shaped structure, and a plug-in structure is formed between the U-shaped structures. The plug-in structure has a first plug-in hole corresponding to the top of the modular socket assembly. The plug-in structure is used to contact the pins of a surge protector or fuse, and the plug-in structure is elastic to grip the pins.
[0025] By providing mounting holes at the bottom of the first socket 10, the second socket 20, and the third socket 30 and connecting them via a busbar, a convenient, stable, and efficient splicing method is provided. When multiple sockets are spliced, the mounting holes are interconnected, and the integrated busbar effectively connects each socket, ensuring smooth current flow and stable connection. The busbar is formed from a single piece of metal, possessing high conductivity and strong mechanical strength, capable of withstanding large current loads and effectively distributing current. Simultaneously, the U-shaped structure and plug-in structure at the bottom of the busbar ensure tight contact with the pins of surge protectors or fuses, guaranteeing a stable connection. The plug-in structure is flexible, firmly gripping the pins and preventing loosening and poor contact. Therefore, it not only improves the reliability of electrical connections but also simplifies the installation process, reduces costs, enhances the overall structural compactness and aesthetics, and ensures that the surge protector continues to provide stable and effective protection during long-term use.
[0026] Preferably, the cross-sections of the first socket 10, the second socket 20, and the third socket 30 are all U-shaped. Limiting baffles are provided on the two opposing inner surfaces of the first socket 10, the second socket 20, and the third socket 30 when they are plugged into the surge protector or fuse. After the modular socket assembly is assembled, the gap between two adjacent limiting baffles is slightly greater than or equal to the width of the surge protector or fuse. When the socket is plugged into the surge protector or fuse, the limiting baffles effectively facilitate the insertion of the surge protector or fuse between two adjacent limiting baffles, ensuring smooth insertion and correct alignment. Furthermore, the gap between two adjacent limiting baffles, slightly greater than or equal to the width of the surge protector or fuse, allows the limiting baffles to provide a certain degree of restraint on the installed surge protector or fuse, ensuring that the surge protector or fuse is stably fixed within the socket assembly, preventing loosening or displacement.
[0027] Preferably, an L-shaped notch is provided on one bottom side of the first socket 10 and one bottom side of the third socket 30 along its length. An L-shaped plate, offset from the L-shaped notch, is provided on one bottom side of the second socket 20 and the other bottom side of the third socket 30 along its length. During assembly of the modular socket assembly, the L-shaped notch and the L-shaped plate are spliced and fastened together. The bottom of the second socket 20 is aligned with that of the first socket 10 or the third socket 30, so that the L-shaped notch and the L-shaped plate are spliced in an offset manner. Then, the two sockets are pressed, so that the two L-shaped notches interlock to form a tight connection. Due to the design of the L-shaped notch, the sockets can not only achieve precise alignment during splicing, but also ensure the stability between the sockets, playing a certain limiting role and avoiding adverse effects caused by loosening or displacement of the sockets.
[0028] Preferably, each of the three inner surfaces of the first socket 10, the second socket 20, and the third socket 30 that come into contact with the surge protector or fuse is provided with a heat sink. Each heat sink has heat dissipation fins on the side away from the surge protector. The heat sinks are all housed within mounting slots provided in the first socket 10, the second socket 20, and the third socket 30. The heat sinks effectively improve the heat dissipation performance of the sockets during operation, preventing overheating from affecting the normal operation of the surge protector or fuse. The heat dissipation fins on the heat sinks further enhance the heat dissipation effect. These heat sinks and fins are all installed in the mounting slots within the sockets, ensuring the stability and durability of the heat dissipation device. Therefore, by optimizing the heat dissipation performance of the sockets, the service life of the equipment is effectively extended, ensuring that the circuit maintains safe and stable operation under high loads or long-term operation.
[0029] This utility model provides a modular socket assembly. First, by designing multiple positioning posts 22 and limiting posts 32 on the sides of the first socket 10, the second socket 20, and the third socket 30, the limiting posts 32 can be inserted into the positioning posts 22 during connection, thereby achieving alignment during connection and facilitating subsequent connection. Next, as the two bases to be spliced approach each other, the second annular protrusion 31 is inserted into the receiving space 24 of the first annular protrusion 21. Then, as they approach each other, the annular rubber ring 34 on the second annular protrusion 31 is engaged in the annular groove 25 and tightened within the annular groove 25. At this time, the two bases to be spliced are tightly connected by the annular rubber ring 34 tightened within the annular groove 25. At the same time, the first annular protrusion 21 is set as a circle, which also enhances the sealing between the sockets after the modular socket assembly is spliced, effectively preventing the intrusion of external contaminants such as dust and moisture, and avoiding the risk of electrical equipment failure or electrical accidents due to poor external environment. Furthermore, the modular design of the modular socket assembly allows for free combination and replacement of sockets according to needs, simplifying the installation and maintenance process. Users can easily replace damaged modules or adjust socket positions, greatly improving operational convenience. Finally, through modular design, socket parts can be highly interchangeable, reducing production and procurement costs while improving product economy and production efficiency. Therefore, the modular socket assembly of this utility model has significant advantages in structural design, ease of installation, safety, and economy, and can meet the multiple requirements of modern power systems for socket assemblies that are efficient, safe, and aesthetically pleasing.
[0030] The above-disclosed embodiments are merely some preferred embodiments of the present utility model, and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
