Description

Technical Field

[0001] This utility model relates to the field of relay technology, specifically to a relay with a welded fixing structure. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity reaches a specified requirement. It is widely used in fields such as automation control, communication, and power electronics.

[0003] In practical applications, relays are typically mounted on a PCB board, with electrical connections achieved through soldering pins to the PCB. Maintaining stable mounting is crucial to prevent loosening or poor contact due to equipment vibration or handling, which could affect normal equipment operation. Current relay mounting methods often rely on simple pin soldering, lacking additional fixing structures. This results in poor relay stability after installation, making the solder joints prone to detachment or loosening under prolonged use or vibration, thus impacting the relay's reliability. Some relays with fixed structures have complex mounting methods, are inconvenient to install and disassemble, and offer poor fixing effects, making them unsuitable for mounting on PCBs of different sizes.

[0004] Therefore, there is an urgent need for a relay with a simple, stable, and easy-to-install welded fixing structure to overcome the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this utility model is to provide a relay with a welding and fixing structure to solve the technical problems mentioned in the background art, such as poor fixing stability when the relay is welded and installed on the PCB board, easy loosening of the weld due to vibration, and inconvenience of installation and disassembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a relay with a welded fixing structure, comprising a relay and a positioning post, wherein pins are provided on a base at the bottom of the relay. The positioning post is inserted into the base at the bottom of the relay, and an arc-shaped spring is connected to the positioning post. Multiple sets of arc-shaped springs are evenly distributed in a ring, and a locking block is fixedly connected to the outer side of each arc-shaped spring. The relay is used for mounting on a PCB board, the pins are inserted into the PCB board and need to be soldered, and the relay is fixedly engaged with the PCB board by the arc-shaped springs on the positioning post.

[0010] Preferably, the top of the positioning post is provided with a threaded end, which is inserted into the inside of the threaded hole, and the positioning post is threadedly connected to the relay through the threaded end and the threaded hole.

[0011] Preferably, a prism segment is fixedly connected below the threaded end, and the prism segment is configured as a nut-shaped hexagonal prism.

[0012] Preferably, the arc-shaped spring is fixedly connected to the bottom of the prism segment, the arc-shaped spring is inserted into the inner side of the retaining ring with an interference fit, and the arc-shaped spring passes through the retaining ring and is fixedly engaged with the retaining ring through the outer retaining block.

An arc-shaped spring 33 is connected to the positioning post 3. Multiple sets of arc-shaped springs 33 are evenly distributed in a ring. A locking block 34 is fixedly connected to the outside of the arc-shaped springs 33. The relay 2 is used for mounting on a PCB board 1. The pin 21 is inserted into the PCB board 1 and needs to be soldered. The relay 2 is fixedly engaged with the PCB board 1 by the arc-shaped springs 33 on the positioning post 3.

[0030] According to the appendix Figure 6 As shown, further, multiple sets of pins 21 are provided, and pins 21 pass through the relay 2 to the inside, respectively connecting to the armature, contacts and coil inside the relay 2.

[0031] According to the appendix Figure 6 As shown, furthermore, the base at the bottom of the relay 2 is provided with threaded holes 22, and multiple sets of threaded holes 22 are arranged in an array.

[0032] According to the appendix Figure 7 As shown, the top of the positioning post 3 is provided with a threaded end 31, which is inserted into the inside of the threaded hole 22. The positioning post 3 is threadedly connected to the relay 2 through the threaded end 31 and the threaded hole 22.

[0033] According to the appendix Figure 7 As shown, a prism segment 32 is fixedly connected below the threaded end 31, and the prism segment 32 is configured as a nut-shaped hexagonal prism.

[0034] According to the appendix Figure 7 As shown, it is particularly important to emphasize that the arc-shaped spring piece 33 is fixedly connected to the bottom of the prism section 32, the arc-shaped spring piece 33 is inserted into the inner side of the retaining ring 11 with an interference fit, the arc-shaped spring piece 33 passes through the retaining ring 11 and is fixedly engaged with the retaining ring 11 through the outer retaining block 34.

[0035] According to the appendix Figures 1-7 As shown, it is particularly important to emphasize that a limiting bolt 35 is inserted into the inner side of the arc-shaped spring piece 33. The limiting bolt 35 is threadedly connected to the arc-shaped spring piece 33 which is distributed in a ring, which can prevent the arc-shaped spring piece 33 from deforming.

[0036] Working principle:

[0037] First, align the threaded end 31 of the positioning post 3 with the threaded hole 22 at the bottom of the relay 2, and use a wrench to rotate the prism section 32 to tighten and fix the positioning post 3 onto the relay 2. Then, align the pin 21 at the bottom of the relay 2 with the insertion hole 12 on the PCB board 1, and at the same time align the arc-shaped spring piece 33 at the bottom of the positioning post 3 with the retaining ring 11 on the PCB board 1. Press the relay 2 down so that the arc-shaped spring piece 33 is slightly deformed under the pressure of the retaining ring 11 until the arc-shaped spring piece 33 passes through the retaining ring 11 and the retaining block 34 is engaged with the bottom of the retaining ring 11, thus achieving the engagement and positioning of the relay 2 and the PCB board 1. Finally, fix the pin 21 to the PCB board 1 by soldering, and tighten the limiting bolt 35 to prevent the arc-shaped spring piece 33 from deforming, thus completing the entire installation process.

[0038] During disassembly, first loosen the limiting bolt 35, use a tool to melt the solder joint, then pinch the arc-shaped spring piece 33 to make it deform slightly, and push the locking block 34 inward to the inside of the retaining ring 11. Then pull the relay 2 upward to separate the locking block 34 from the retaining ring 11, and the relay 2 can be removed from the PCB board 1. If the positioning post 3 needs to be replaced, the prism section 32 can be rotated with a wrench to unscrew the positioning post 3 from the relay 2.

[0039] In this embodiment, the arc-shaped spring 33 is set to 4 groups, and the threaded hole 22 is set to 4 groups. The number of arc-shaped springs 33 and threaded holes 22 can be adjusted according to actual fixing requirements. The retaining ring 11 is made of stainless steel and can be replaced with other high-strength metal materials according to actual usage scenarios. The prism segment 32 is set as a hexagonal prism, or it can be set as other polygonal structures according to operational requirements. None of these will affect the implementation effect of this utility model.
