Description

Technical Field

[0001] This utility model relates to an AC contactor and belongs to the field of AC contactors. Background Technology

[0002] An AC contactor is an electrical device used in industrial electricity that uses the magnetic field generated by the current flowing through a coil to close the contacts, thereby controlling the load.

[0003] Existing AC contactors require a coil to be wound around a copper sheet, and then the copper sheet with the coil wound around it is injection molded to isolate and protect the winding. This may cause damage to the assembled coil, and the processing efficiency is slow, the packaging requirements are high, the lifespan of the coil is shortened, and the difficulty of the process is greatly increased. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an AC contactor.

[0005] An AC contactor includes a sliding base and a control module slidably connected to a housing. The sliding base has a mounting groove for mounting a winding, a mounting seat within the mounting groove, and a receiving cavity within the mounting seat for the winding to extend into. Limiting portions on both sides of the receiving cavity are provided for limiting connection with the winding. By providing a mounting groove on the base for mounting the winding, and configuring the mounting seat and receiving cavity within the groove, a stable installation and effective protection of the winding can be achieved without directly injection molding the copper sheet, avoiding damage to the winding during assembly or packaging. The limiting portions on both sides of the receiving cavity limit and fix the winding, preventing loosening or displacement during operation, thereby improving the stability and reliability of the AC contactor. The modular mounting structure replaces the traditional injection molding method, significantly simplifying the processing flow, reducing the requirements for the packaging process, and decreasing manufacturing costs and time. The new structural design avoids the possibility of thermal damage to the coil caused by high-temperature injection molding, improving the coil's operating environment and effectively extending its service life. With pre-set mounting slots and mounting bases, the windings can be quickly positioned and assembled, shortening assembly time and improving overall production efficiency.

[0006] Preferably, the mounting base has a first fixing part and a second fixing part on its upper and lower sides. The first and second fixing parts are designed in a ring shape and are fitted over the winding located in the middle to isolate the windings from each other. The ring shape of the first and second fixing parts can wrap around and limit the upper and lower ends of the winding, providing physical isolation and effectively preventing contact or interference between the windings, thus improving the electrical safety of the product. The upper and lower ring fixing parts can provide stable support for the windings, preventing them from shifting or loosening due to external vibration or magnetic field impact during use, thereby improving the operational reliability of the contactor under harsh conditions. This structure facilitates the standardized installation of the windings, ensuring that each winding maintains a uniform position and posture during assembly, thereby improving assembly consistency and product qualification rate.

[0007] Furthermore, the first fixing part has a raised rim around its outer periphery, and a buckle that engages with the rim is located within the mounting groove. The raised rim and its engagement with the buckle in the mounting groove ensure secure positioning, preventing the mounting base from loosening or falling off due to vibration or impact during operation, thus enhancing the overall structural reliability. The engagement between the rim and the buckle provides excellent assembly convenience, allowing installation or replacement without additional tools, which improves production assembly efficiency and simplifies subsequent maintenance. The raised rim provides reinforced support for the edge of the mounting base, enhancing its overall resistance to deformation and protecting the internal windings from external forces. The precise fit between the rim and the buckle makes the mounting structure more compact, making efficient use of the internal space of the mounting groove, which contributes to miniaturization or improves the overall structural integration of the machine.

[0008] Furthermore, the second fixing part has positioning parts extending towards the base on both sides. Each positioning part has a horizontally arranged first sliding groove, and the outer casing has a sliding strip for sliding engagement with the sliding groove. By providing positioning parts extending to the base in the second fixing part, and having horizontal sliding grooves on them, allowing for sliding engagement with the sliding strip inside the outer casing, the base can be effectively guided to move smoothly in a predetermined direction. This sliding connection method maintains flexible assembly while also providing strong limiting effect, simplifying the assembly process, and facilitating maintenance and replacement of windings or other internal components.

[0009] Preferably, the sliding base is equipped with a control chamber for housing the control module, and a protective cover is installed outside the control chamber. By establishing an independent control chamber on the sliding base and installing a protective cover on its exterior, the control module can be effectively prevented from being interfered with by external factors such as dust and moisture, improving the adaptability of the equipment in various complex industrial environments. The external protective cover has a certain physical protection capability, preventing damage to the control module from external impacts during equipment transportation, installation, or operation, and enhancing the overall structure's resistance to damage. The control chamber, as the installation space for functional modules, facilitates centralized assembly, disassembly, and replacement of the control modules. Combined with the detachable protective cover structure, it improves maintenance efficiency and ease of use. Compared to traditional, cramped installation spaces, the control chamber provides a large amount of space leeway, facilitating use and wiring.

[0010] Furthermore, the control room is located at the front end of the sliding base and is used for electrical connection with external equipment. Positioning the control room at the front end of the sliding base facilitates quick and direct electrical connection between the control module and external circuits or control systems, reducing connection paths and improving conductivity and connection stability. The front-end location of the control room also makes the interfaces with external equipment more centralized and clearly defined, which is beneficial for unified wiring and interface layout, improving the standardization and convenience of installation and maintenance.

[0011] Preferably, the sliding base has second sliding grooves on both sides, and the sliding strip inside the housing is slidably connected to the second sliding grooves. By providing second sliding grooves on both sides of the sliding base and slidably engaging with the sliding strip inside the housing, the swaying or offset of the sliding base can be effectively limited based on multi-point guidance, thereby improving the stability and smoothness of the movement process.

[0012] Furthermore, the second sliding groove is disposed on the extension block, and the bottom of the extension block is provided with an elastic part for sliding against the bottom of the outer shell. The elastic part is hollow. The hollow elastic part has good deformation recovery characteristics, and can deform briefly and rebound quickly when subjected to pressure or displacement, providing flexible support for the sliding of the base, while improving the adaptability and lifespan of the structure.

[0013] The beneficial effects of this utility model are as follows: By setting an installation groove for mounting the winding on the base, and configuring a mounting seat and receiving cavity within the groove, a stable installation and effective protection of the winding can be achieved without directly injection molding the copper sheet, avoiding damage to the winding during assembly or packaging. Limiting parts are provided on both sides of the receiving cavity, which can limit and fix the winding, preventing loosening or displacement during operation, thereby improving the stability and reliability of the AC contactor. The modular installation structure replaces the traditional injection molding packaging method, significantly simplifying the processing flow, reducing the requirements for the packaging process, and decreasing manufacturing costs and time. The new structural design avoids the possibility of thermal damage to the coil caused by high-temperature injection molding, improving the coil's operating environment and effectively extending its service life. The pre-set installation groove and mounting seat allow the winding to be quickly positioned and assembled, shortening assembly time and improving overall production efficiency.

[0026] like Figure 1-7The diagram illustrates an embodiment of an AC contactor according to this invention. It includes a sliding base 2 and a control module slidably connected to a housing 1. The sliding base 2 has a mounting groove 21 for mounting a winding 4. A mounting seat 3 is located within the mounting groove 21. The mounting seat 3 has a receiving cavity 31 for the winding 4 to extend into. Limiting portions 32 for limiting connection with the winding 4 are located on both sides of the receiving cavity 31. By providing a mounting groove 21 for mounting the winding 4 on the base, and configuring the mounting seat 3 and receiving cavity 31 within the groove, a stable installation and effective protection of the winding 4 can be achieved without directly injection molding the copper sheet, preventing damage to the winding 4 during assembly or packaging. The limiting portions 32 on both sides of the receiving cavity 31 limit and fix the winding 4, preventing loosening or displacement during operation, thereby improving the stability and reliability of the AC contactor. The modular mounting structure replaces the traditional injection molding packaging method, significantly simplifying the processing flow, reducing the requirements for the packaging process, and decreasing manufacturing costs and time. The new structural design avoids the possibility of thermal damage to the coil caused by high-temperature injection molding, improves the operating environment of the coil, and thus effectively extends the service life of the coil. The pre-set mounting slot 21 and mounting base 3 enable the winding 4 to be quickly positioned and assembled, shortening assembly time and improving overall production efficiency.

[0027] The mounting base 3 has a first fixing part 33 and a second fixing part 35 on its upper and lower sides. The first fixing part 33 and the second fixing part 35 are designed in a ring shape and are fitted over the winding 4 located in the middle to isolate the windings 4 from each other. The ring shape of the first fixing part 33 and the second fixing part 35 can wrap around and limit the upper and lower ends of the winding 4, playing a role in physical isolation and effectively preventing contact or interference between the windings 4, thereby improving the electrical safety of the product. The upper and lower ring fixing parts can provide stable support for the winding 4, preventing it from shifting or loosening due to external vibration or magnetic field impact during use, thereby improving the operational reliability of the contactor under harsh conditions. This structure is conducive to the standardized installation of the windings 4, ensuring that each winding 4 maintains a uniform position and posture during assembly, thereby improving assembly consistency and product qualification rate.

[0028] In this embodiment, unlike the previous embodiment, the first fixing part 33 has a raised periphery 34, and the mounting groove 21 has a buckle 22 that engages with the periphery 34. The raised periphery 34 of the first fixing part 33, engaging with the buckle 22 in the mounting groove 21, ensures secure positioning, preventing the mounting base 3 from loosening or falling off due to vibration or impact during operation, thus enhancing the overall structural reliability. The engagement between the periphery 34 and the buckle 22 provides excellent assembly convenience, allowing installation or replacement without additional tools, which improves production assembly efficiency and simplifies subsequent maintenance. The raised periphery 34 provides reinforced support for the edge of the mounting base 3, enhancing its overall resistance to deformation and protecting the internal winding 4 from external forces. The precise engagement between the periphery 34 and the buckle 22 makes the mounting structure more compact, rationally utilizing the internal space of the mounting groove 21, which contributes to miniaturization or improves the overall structural integration.

[0029] The second fixing part 35 has positioning parts 36 extending towards the base on both sides. Each positioning part 36 has a horizontally arranged first sliding groove 37. The outer casing 1 has a sliding strip 11 for sliding engagement with the sliding groove. By providing positioning parts 36 extending to the base on the second fixing part 35 and having horizontal sliding grooves on them, which then slide and engage with the sliding strip 11 inside the outer casing 1, the base can be effectively guided to move smoothly in a predetermined direction. This sliding connection method maintains flexible assembly while also providing strong limiting function, simplifying the assembly process and facilitating maintenance and replacement of the winding 4 or other internal components.

[0030] In this embodiment, unlike the previous embodiments, a control chamber 23 is provided on the sliding base 2. The control chamber 23 is used to house the control module, and a protective cover 24 is installed outside the control chamber 23. By establishing an independent control chamber 23 on the sliding base 2 and installing a protective cover 24 outside it, the control module can be effectively prevented from being interfered with by external factors such as dust and moisture, improving the adaptability of the equipment in various complex industrial environments. The external protective cover 24 has a certain physical protection capability, preventing damage to the control module caused by external impacts during equipment transportation, installation, or operation, and enhancing the overall structure's resistance to damage. The control chamber 23 serves as the installation space for functional modules, making it easy to centrally assemble, disassemble, and replace the control modules. Combined with the detachable protective cover 24 structure, it improves maintenance efficiency and ease of use. Compared to the traditional cramped installation space, the control chamber 23 provides a large amount of space leeway, facilitating use and wiring.

[0031] The control room 23 is located at the front end of the sliding base 2 and is used for electrical connection with external equipment. Positioning the control room 23 at the front end of the sliding base 2 facilitates quick and direct electrical connection between the control module and external circuits or control systems, reducing connection paths and improving conductivity and connection stability. The front-end placement of the control room 23 also makes the interfaces with external equipment more centralized and clearly defined, which is beneficial for unified wiring and interface layout, improving the standardization and convenience of installation and maintenance.

[0032] The sliding base 2 has second sliding grooves 26 on both sides, and the sliding strip 11 inside the outer shell 1 is slidably connected to the second sliding grooves 26. By providing second sliding grooves 26 on both sides of the sliding base 2 and slidingly engaging with the sliding strip 11 inside the outer shell 1, the swaying or offset of the sliding base 2 can be effectively limited based on multi-point guidance, thereby improving the stability and smoothness of the movement process.

[0033] In this embodiment of the application, unlike the embodiments described above, the second sliding groove 26 is disposed on the extension block 25, and the bottom of the extension block 25 is provided with an elastic portion 27 for sliding against the bottom of the outer casing 1. The elastic portion 27 is hollow. The hollow elastic portion 27 has good deformation recovery characteristics, and can deform briefly and rebound quickly when subjected to pressure or displacement, providing flexible support for the sliding of the base, while improving the adaptability and lifespan of the structure.

Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
