Description

Technical Field

[0001] This utility model relates to the field of relay technology, and in particular to a multi-purpose relay. Background Technology

[0002] An electromagnetic relay is an electrical control device. When current passes through the coil of an electromagnetic relay, a magnetic field is generated, which attracts the iron core to move, thereby pushing the contacts to close or open, thus realizing the control of the circuit.

[0003] A relay mentioned in an existing Chinese patent (authorization announcement number: CN218299711U) can, through the design of the blocking component, fix the voltage isolator by picking it up and inserting it into the groove opened at the top of the extension part along the "U" shaped through-hole. With the cooperation of the voltage isolator, the first extension block and the second extension block, the electrical influence of the high voltage end on the low voltage end is completely blocked, which enhances the high voltage withstand value of the product, avoids breakdown, and makes the use of electrical appliances safer.

[0004] With the development and continuous iteration of the electronics industry, especially energy and electrical control technology, the requirements for relays are becoming increasingly demanding. These requirements are not only reflected in electrical characteristics, but also in product structure and space utilization. To adapt to the same electrical characteristics, it is necessary to develop multiple products of different sizes to meet customer needs and to carry out small-batch, multi-batch procurement and delivery. This may make the mold, production line, and product management of relay manufacturers increasingly complex, resulting in a waste of assets and management. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the procurement and delivery of small batches and multiple deliveries may cause complex mold, production line and product management for relay manufacturers. This utility model provides a multi-purpose relay.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A multi-purpose relay includes a base, on which frames are symmetrically fixedly connected to both sides of the top of the base. An iron frame is fixedly connected to the top of the frames. A coil is mounted on the top of the base, and an iron core is mounted on the top of one side of the frames. A fixing mechanism is provided on the outer side of the frames, and an elastic mechanism is provided on the top of the iron frame. The fixing mechanism includes a fixing bracket on the top of the frames, a fixing terminal fixedly connected to the bottom of the fixing bracket, an elastic block I fixedly connected to the top of the fixing bracket, and a fixing block fixedly connected to the top of the elastic block I. Two sets of connecting holes are symmetrically opened on the outer side of the fixing bracket, and a terminal extension block is provided on the outer side of the fixing bracket, connecting to the fixing bracket through the connecting holes. A mounting block is fixedly connected to the top of the iron frame, and a slot is opened on the inner side of the mounting block. A connecting block is provided on the inner side of the slot, and a contact is mounted on the bottom of the connecting block. An elastic block II is provided between the connecting block and the contact. A magnetic blow-out bracket is mounted on the top of the base, and a locking groove is opened on the outer side of the magnetic blow-out bracket, the locking groove being adapted to the frames and the base.

[0008] By adopting the above technical solution, the relay coil 2 is first energized. The current generates magnetic flux in the iron core 5, thus forming a magnetic field. When the electromagnetic force is large enough, the armature overcomes the spring tension and moves towards the iron core 5. The movement of the contact 15 achieves the purpose of connecting or disconnecting the load circuit, completing the current control. After use, the current to the coil 2 is released, and the magnetic field disappears, allowing the relay to return to its initial state. The fixing mechanism overcomes the problem of magnetic circuit dispersion or instability caused by the thickness tolerance of the magnetic core 6. The elastic mechanism saves on the length of the terminals and the amount of copper material used. The fixing bracket and fixing terminals... The integrated design, with the first elastic block made of polyurethane elastomer, provides a degree of flexibility, allowing for a more thorough integration of the magnetic core with the iron frame and iron core. The connection holes facilitate the easy access of terminals for other connection methods, improving the relay's applicability. Utilizing the iron frame and elastic mechanism as conductors, and achieving electrical connection with normally closed terminals via moving contacts, saves on terminal length and copper usage, improving the applicability of normally closed terminal electrical connections. The second elastic block further enhances the applicability of normally closed terminal electrical connections. The magnetic blowout bracket and fixed bracket tightly integrate the frame and base, reducing the molding difficulty of the frame and base.

[0009] In summary, this utility model has at least one of the following beneficial effects;

[0010] 1. This utility model integrates the fixed bracket and fixed terminal into one design, and uses an elastic block made of polyurethane elastomer, which has a certain degree of flexibility, so that the magnetic core is more fully integrated with the iron frame and the iron core, thereby overcoming the problem of magnetic circuit dispersion or instability caused by magnetic core thickness tolerance.

[0011] 2. This utility model uses an iron frame and elastic mechanism as conductors, and achieves electrical connection with normally closed terminals through moving contacts, saving the length of terminals and the amount of copper material used, thereby reducing costs, and realizing the circuit planning of connecting the upper and lower parts, saving a large amount of copper material.

[0019] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0020] This utility model discloses a multi-purpose relay.

[0021] Reference Figures 1 to 5A multi-purpose relay includes a base 1, with frames 3 symmetrically fixedly connected to both sides of the top of the base 1. An iron frame 4 is fixedly connected to the top of the frames 3. A coil 2 is mounted on the top of the base 1. An iron core 5 is mounted on the top of one side of the frame 3. A fixing mechanism is provided on the outer side of the frame 3. An elastic mechanism is provided on the top of the iron frame 4. The fixing mechanism includes a fixing bracket 7 on the top of the frame 3, a fixing terminal 8 fixedly connected to the bottom of the fixing bracket 7, an elastic block 9 fixedly connected to the top of the fixing bracket 7, and a fixing block 19 fixedly connected to the top of the elastic block 9. The outer side of the fixing bracket 7... Two sets of connecting holes 10 are symmetrically arranged. Terminal extension blocks are provided on the outer side of the fixed bracket 7. The terminal extension blocks are connected to the fixed bracket 7 through the connecting holes 10. The top of the iron frame 4 is fixedly connected to the mounting block 11. The inner side of the mounting block 11 is provided with a slot 12. The inner side of the slot 12 is provided with a connecting block 14. The bottom of the connecting block 14 is provided with a contact 15. An elastic block 16 is provided between the connecting block 14 and the contact 15. The top of the base 1 is provided with a magnetic blow-out bracket 17. The outer side of the magnetic blow-out bracket 17 is provided with a locking groove 18. The locking groove 18 is adapted to the frame 3 and the base 1.

[0022] When using a relay, first energize the relay coil 2. The current will generate magnetic flux in the iron core 5, thus forming a magnetic field. When the electromagnetic force is large enough, the armature will overcome the spring tension and move towards the iron core 5. The movement of the contact 15 achieves the purpose of conducting or cutting off the load circuit, completing the current control. After use, the current to the coil 2 is released, and the magnetic field also disappears, allowing the relay to return to its initial state. The fixing mechanism can overcome the problem of magnetic circuit dispersion or instability caused by the thickness tolerance of the magnetic core 6. The elastic mechanism saves the length of the terminals and the amount of copper material used.

[0023] By integrating the fixed bracket 7 and the fixed terminal 8, and using the elastic block 9 as a polyurethane elastomer, which has a certain degree of flexibility, the magnetic core 6 is more fully integrated with the iron frame 4 and the iron core 5. This overcomes the problem of magnetic circuit dispersion or instability caused by the thickness tolerance of the magnetic core 6, and reduces the precision requirements for the size of the magnetic core 6 during the production process. It also allows for greater flexibility in selecting the material or manufacturing process of the magnetic core 6, reducing the inconvenience of developing multiple products of different sizes.

[0024] Furthermore, terminals for other connection methods can be easily led out through the connection hole 10, improving the applicability of the relay.

[0025] By using the iron frame 4 and the elastic mechanism as conductors, and achieving electrical connection with the normally closed terminal through the moving contact 15, the length of the terminal and the amount of copper material are saved, thereby reducing the cost. It also realizes the circuit planning of connecting the top and bottom, saving a lot of copper material.

[0026] The frame 3 and the base 1 are tightly joined together by the magnetic blow-out bracket 17 and the fixed bracket 7, which reduces the molding difficulty of the frame 3 and the base 1 and achieves precise fit between the parts.

[0027] Working principle: When the coil 2 of the relay is energized, the current will generate magnetic flux in the iron core 5, thus forming a magnetic field. When the electromagnetic force is large enough, the armature will overcome the tension of the spring and move towards the iron core 5. The movement of the contact 15 achieves the purpose of conducting or cutting off the load circuit, completing the current control. After use, the current to the coil 2 is released, and the magnetic field also disappears, allowing the relay to return to its initial state. Through the integrated design of the fixed bracket 7 and the fixed terminal 8, and the elastic block 9 being made of polyurethane elastomer, it has a certain degree of flexibility, making the magnetic core 6 more fully integrated with the iron frame 4 and the iron core 5, thereby overcoming the problem of magnetic circuit dispersion or instability caused by the thickness tolerance of the magnetic core 6.
