Description

Technical Field

[0001] This utility model relates to the field of relay technology, specifically to a modular relay base. Background Technology

[0002] A relay is an electrical control device that uses electromagnetic induction or other physical effects to achieve automatic control, switching, and protection functions for circuits. The relay base is a supporting component that provides a stable mounting surface and electrical connection platform for the relay. In practical applications, the relay's pins are inserted into corresponding pin slots on the base (such as pin 1, pin 2, etc.). The conductive elastic plate and contact structures inside the base (such as contact one, contact two) make close contact with the relay pins, forming a stable electrical path, allowing the relay to be safely and reliably connected to the circuit.

[0003] Given the increasingly complex and diverse application scenarios of relays, traditional integrated relay bases are unable to meet diverse installation needs. Traditional bases are typically monolithic structures, which suffer from poor installation flexibility and difficulty in adapting to complex wiring when dealing with space-constrained, distributed, or modular circuit systems. Furthermore, when part of the base is damaged, the entire unit must be replaced, increasing maintenance costs. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 In this embodiment of the present invention, a modular relay base includes a relay housing 1. Four sets of modular mounting plates 2 are placed at the bottom of the inner cavity of the relay housing 1. A first pin slot 3 is formed through one edge of one set of modular mounting plates 2. A second pin slot 4 is formed in the middle of one of the first pin slots 3. A third pin slot 5 is formed on one side of the modular mounting plate 2 near the second pin slot 4. A fourth pin slot 6 is formed on one side of the modular mounting plate 2 away from the first pin slot 3. During assembly, firstly, pin 1 8 is embedded into the first pin slot 3, ensuring a secure connection between the top of pin 1 8 and the relay assembly 24. Subsequently, pins 2 9, 3 13, and 4 15 are sequentially installed into the second pin slot 4, the third pin slot 5, and the fourth pin slot 6, respectively.

Multiple slots 19 are opened on the upper part of the splicing mounting plate 2 on the side away from the first pin slot 3, and insertion rods 17 cooperate with slots 19. Multiple slots 20 are opened on the lower part of the splicing mounting plate 2 on the side of slots 19, and slots 20 cooperate with insertion rods 28. After the pin assembly is completed, insertion rods 17 and insertion rods 28 on each set of splicing mounting plates 2 are inserted into slots 19 and slots 20 opened on the other side of the adjacent splicing mounting plate 2, respectively. Through this mortise and tenon joint structure, the four sets of splicing mounting plates 2 are tightly fixed.

[0025] A splicing baffle 21 is installed on one side of the four sets of splicing mounting plates 2. Multiple slots 3 22 are opened on the upper part of the side of the splicing baffle 21 near the splicing mounting plate 2, and slots 3 22 cooperate with the first insertion rod 17. Multiple slots 4 23 are opened on the lower part of the side of the splicing baffle 21 near the splicing mounting plate 2, and slots 4 23 cooperate with the second insertion rod 18. After the four sets of splicing mounting plates 2 are spliced, the splicing baffle 21 is used to seal and protect the pin mounting side. During splicing, the first insertion rod 17 and the second insertion rod 28 are precisely inserted into the preset slots 3 22 and slots 4 23 of the splicing baffle 21 to form a complete base frame.

[0026] The relay assembly 24 is installed inside the relay housing 1. The bottom of the relay assembly 24 is provided with four pressure rods 25, and the pressure rods 25 penetrate through the splicing mounting plate 2. The pressure rods 25 inside the relay are driven by an electromagnetic coil or spring force to move up and down, thereby controlling the opening and closing of the contacts and ensuring the transmission and switching of circuit signals. This is existing technology and will not be described in detail here.

[0027] A set of first pin slots 3 has its inner cavity penetrating the splicing mounting plate 2 and housing pin 8. The top of pin 8 also penetrates the splicing mounting plate 2 and is connected to the relay assembly 24. A set of second pin slots 4 has its inner cavity penetrating the splicing mounting plate 2 and housing pin 9. A conductive elastic plate 10 is installed on one side of pin 9 within the inner cavity of the splicing mounting plate 2. A contact 11 is installed on the upper part of the conductive elastic plate 10 on the side away from pin 29. A contact 16 is installed on the side of the conductive elastic plate 10 away from contact 16. A second contact 12 is provided. A third contact 13 is installed through the inner cavity of the third pin slot 5. A third contact 14 is installed on one side of the inner cavity of the splicing mounting plate 2, and the third contact 14 abuts against the second contact 12. A pin slot 7 is provided on the side of the inner cavity of the splicing mounting plate 2 near the fourth pin slot 6. A fourth contact 15 is installed through the inner cavity of the fourth pin slot 6, and the fourth contact 15 is located on one side of the inner cavity of the splicing mounting plate 2 and cooperates with the pin slot 7. Pin 1 (8) is inserted into the first pin slot 3, ensuring a secure connection between the top of pin 1 (8) and the relay assembly 24. Then, pins 2 (9), 3 (13), and 4 (15) are sequentially installed into the second pin slot 4, third pin slot 5, and fourth pin slot 6, respectively. Pin 4 (15) has a contact 4 (16) installed on the bottom side of the inner cavity of the mounting plate 2, and contact 4 (16) abuts against contact 1 (11). Four pressure rods 25 penetrate one side of the mounting plate 2 and abut against the conductive elastic plate 10. The pressure rod 25 inside the shell vertically penetrates the splicing mounting plate 2 and forms a linkage structure with the conductive elastic plate 10. When the pressure rod 25 is pressed down, the conductive elastic plate 10 is deformed by force, and the second contact 12 on one side of it is tightly attached to the third contact 14 on the top of the third pin 13, completing the circuit conduction. When the pressure rod 25 is reset, the conductive elastic plate 10 rebounds by its own elasticity, causing the first contact 11 on its top to reliably contact the fourth contact 16 on the side of the fourth pin 15, realizing the switching of circuit state and stable connection.

[0028] The working principle of this utility model is as follows: During the splicing and installation, firstly, pin 8 is embedded into the first pin slot 3, ensuring that the top of pin 8 is securely connected to the relay assembly 24. Subsequently, pins 9, 13, and 15 are sequentially installed into the second pin slot 4, third pin slot 5, and fourth pin slot 6, respectively. After the pin assembly is completed, the first pin 17 and the second pin 18 on each splicing mounting plate 2 are inserted into the slots 19 and 20 on the other side of the adjacent splicing mounting plate 2, respectively. Through this mortise and tenon joint structure, the four splicing mounting plates 2 are tightly fixed. After the four splicing mounting plates 2 are spliced, the splicing baffle 21 is used to seal and protect the pin installation side. At this time, the first insertion rod 17 and the second insertion rod 18 are precisely inserted into the pre-set slots 22 and 23 of the splicing baffle 21 to form a complete base frame. Finally, the assembled base assembly is embedded into the relay housing 1. At this time, the pressure rod 25 inside the housing penetrates vertically through the splicing mounting plate 2 and forms a linkage structure with the conductive elastic plate 10. When the pressure rod 25 is pressed down, the conductive elastic plate 10 is deformed by force, and the second contact 12 on one side of it and the third contact 14 on the top of the third pin 13 are tightly attached to complete the circuit conduction. When the pressure rod 25 is reset, the conductive elastic plate 10 rebounds with its own elasticity, so that the first contact 11 on its top and the fourth contact 16 on the side of the fourth pin 15 can reliably contact, realizing the switching of the circuit state and stable connection.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
