Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a reactor quick-connect terminal assembly. Background Art

[0002] Reactors for variable-frequency air conditioners generally have two wiring methods, depending on their rated current: 250# quick-connect terminals, commonly used for reactors with currents below 30A; and screw-type terminals, secured with M5 screws and commonly used for higher currents, 30A to 70A. Because the screw-type terminals are irregularly shaped, they are impregnated together with the reactor using a vacuum impregnation process. To prevent contamination from insulating paper, the threaded terminals are wrapped with high-temperature tape before impregnation.

[0003] Traditional threaded terminals are made of flexible terminal assemblies made of insulating paper and fixed to the reactor coil using glass cloth tape. Because the insulating paper is flexible, the terminal assembly can exhibit different shapes for different products and coils after being fixed, resulting in poor product consistency. Insulating varnish often remains inside the threaded terminals, and customers often increase the torque applied to the screws during use. Due to the insufficient tear resistance of the insulating paper, the insulation often tears. Furthermore, when connecting the terminal to the wire, the difference in conductor diameter or cross-sectional area can make connecting the coil to the threaded terminal difficult, or require additional connectors to connect the two, reducing actual production efficiency and increasing labor costs.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 , this utility model provides two technical solutions:

[0024] The first embodiment: A reactor quick-connect terminal assembly includes a base plate 1, an extension plate is provided at one end of the base plate 1, and fixing claws 11 are provided on both sides of the extension plate. The fixing claws 11 can be bent by sheet metal. The upper surface of the base plate 1 is fixed with a reactor core 2 by bolts, and the middle part of the reactor core 2 is sleeved with a reactor coil 3. A terminal block 4 is provided on one side of the reactor core 2, and the bottom end of the terminal block 4 is connected to the base plate 1. The terminal block 4 is made of PET material and is used to improve the strength of the terminal block 4, thereby improving the yield rate of finished product inspection. Mounting grooves 41 are provided on both sides of the top of the terminal block 4, and the threaded terminals 5 are inserted into the mounting grooves 41. The bottom end of the terminal block 4 is fixed with a mounting plate 42, and the mounting plate 42 is connected to the fixing claw 11 sheet metal on the base plate 1. When installing, the fixing claw 11 sheet metal is bent, and the mounting plate 42 can be limited to the extension plate on the base plate 1, so that the terminal block 4 can be fixed on the base plate 1.

[0025] The second embodiment is mainly different from the first embodiment in that: two symmetrically distributed threaded terminals 5 are provided on the terminal block 4, and a connecting plate 51 is fixed at one end of the threaded terminal 5. The connecting plate 51 is arranged vertically to the threaded terminal 5, and limiting claws 52 are fixed on both sides of the upper end of the connecting plate 51. The limiting claws 52 correspond to the outer side of the lower end opening of the installation slot 41. The limiting claws 52 play a limiting role after the sheet metal is bent, limiting the threaded terminal 5 in the installation slot 41, so that the threaded terminal 5 can be quickly and conveniently limited and fixed. A wiring card plate 53 is connected to the middle part of the lower end of the connecting plate 51. The wiring card plate 53 cooperates with the connecting plate 51 to form an "h"-shaped structure, which is used to limit the wires of the reactor, thereby improving the compatibility of the device with wires of different wire diameters and different cross-sectional areas. A matching groove is opened in the middle part of the bottom end of the connecting plate 51, and the matching groove corresponds to the wiring card plate 53.

[0026] When installing this device, first insert the threaded terminal 5 into the mounting groove 41 on the terminal block 4 until the threaded terminal 5 is fully inserted. At this time, the limiting claw 52 on the connecting plate 51 is located below the mounting groove 41. Then, the limiting claw 52 is bent by sheet metal to play a limiting role, and the threaded terminal 5 is limited on the terminal block 4. Then, the terminal block 4 is placed on the base plate 1 after varnish dipping and drying, and the mounting plate 42 on the terminal block 4 is set between the two fixing claws 11. Then, the fixing claw 11 is bent by sheet metal to hold the mounting plate 42 on the terminal block 4 tightly, and the terminal block 4 is limited on the base plate 1. Finally, the lead of the reactor is clamped into the inner side of the wiring card plate 53, and then the incoming line card plate is clamped with pliers, and then fixed with soldering iron to obtain the finished product.
