Description

Technical Field

[0001] This utility model relates to an electronic component, specifically to a relay with a quick-connect structure. Background Technology

[0002] In the field of industrial control and power equipment, intermediate relays, as core components for signal transmission and circuit switching, directly affect system operating efficiency due to their structural reliability and ease of operation. Currently, the widely used intermediate relay plug-in structures generally employ mechanical threaded connections or screw crimping methods, which have gradually revealed multiple technical defects in practical applications.

[0003] First, traditional plug-in methods require the use of tools such as screwdrivers for tightening. In confined spaces or densely packed equipment, installers often face challenges such as limited operating angles and repetitive tightening in multiple steps. Especially in harsh working conditions such as high temperatures and dust, the use of protective gloves further reduces the accuracy of manual operation.

[0004] Secondly, continuous impact under mechanical vibration environment can easily cause micro-displacement of threaded pairs, uneven pressure distribution on the contact surface leading to increased contact resistance, and the gradual formation of oxide film and arc erosion during long-term operation, resulting in signal transmission distortion or even contact adhesion failure.

[0005] In addition, the fasteners must be completely removed before the relay body can be separated during maintenance and repair. This not only prolongs the equipment downtime, but repeated disassembly and assembly can also cause secondary damage such as stripped threads and cracked housings. Utility Model Content

[0006] To address the technical problem of inconvenient insertion and removal caused by the mechanical threaded connection of the intermediate relay in the prior art, this utility model provides a relay with a quick connection structure. By setting a connecting part on the base and setting a buckle and a button on the mounting part of the coil bracket, quick installation and removal can be achieved by the button driving the buckle and matching the buckle with the connecting part.

[0019] Optionally, the elastic force of the support spring is greater than the sum of the elastic forces of the two tension springs.

[0020] Optionally, there is a gap between the vertical plane of the rotating connecting shaft of the buckle on the coil bracket and the vertical plane of the connection point of the tension spring on the buckle.

[0021] Optionally, the distance between the two buckle rotation shafts is greater than the distance between the two tension springs.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] By setting a connecting part on the base and a rotating buckle and a sliding button on the mounting part of the coil bracket, when it is necessary to install the relay on the base, press the button so that the bottom of the button presses the top of the buckle, thereby driving the buckle to rotate and the bottom of the buckle to move outward.

As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] Example:

[0034] See Figure 1 , Figure 2 and Figure 3 This embodiment discloses a relay with a quick-connect structure, including a base 10, a coil bracket 20, a snap-fit ​​30, and a button 40. The base 10 has connecting portions 11 on both sides, and the coil bracket 20 houses the main components of the relay, including an induction coil.

[0035] In addition, a mounting part 21 is provided on one side of the coil bracket 20, and a buckle 30 is rotatably provided at the bottom of the mounting part 21. The middle part of the buckle 30 is rotatably connected to the mounting part 21, and the bottom of the buckle 30 can match the connecting part 11 on the base 10.

[0036] Button 40 is slidably mounted on mounting part 21 of coil bracket 20, and button 40 is located above buckle 30 and can contact the top of buckle 30. At the same time, when button 40 is pressed, the bottom of button 40 can drive buckle 30 to rotate.

[0037] The working principle of this embodiment is as follows: by setting a connecting part 11 on the base 10, and setting a rotating buckle 30 and a sliding button 40 on the mounting part 21 of the coil bracket 20, when it is necessary to install the relay on the base 10, press the button 40 so that the bottom of the button 40 presses the top of the buckle 30, thereby driving the buckle 30 to rotate and the bottom of the buckle 30 to move outward. Then, place the relay on the base 10, release the button 40, and the buckle 30 will be locked in the connecting part 11.

[0038] Conversely, when the relay needs to be disassembled, press button 40 to separate the bottom of clip 30 from the connecting part 11, and then you can take the relay away.

[0039] In this technical solution, the buckle 30 is driven by the button 40, and quick installation and disassembly are achieved by matching the buckle 30 with the connecting part 11.

[0040] In one specific embodiment:

[0041] Two buckles 30 are symmetrically provided at the bottom of the mounting part 21. The bottom of the button 40 is poweredly connected to the top of the two buckles 30. A connecting part 11 is provided on each side of the base 10. The two buckles 30 can be matched with the two connecting parts 11 respectively.

[0042] In this embodiment, a stable connection between the relay and the base 10 is achieved by providing two snap-fits 30 and two connecting parts 11.

[0043] In another specific embodiment:

[0044] Tension springs 50 are provided at the top of the buckle 30 and the bottom of the button 40. When the button 40 is not subjected to external force, the tension spring 50 is in a stretched and straightened state, thereby generating an upward pulling force on the buckle 30 through the tension of the tension spring 50, so that the bottom of the buckle 30 is tightly locked on the connecting part 11.

[0045] When it is necessary to release the buckle 30, press the button 40. The button 40 presses the tension spring 50, which is then compressed, thereby driving the top of the buckle 30 to rotate downward.

[0046] Preferably, the connecting portion 11 on the base 10 is a concave groove, the inner side of the buckle 30 is a C-shaped structure, and the two buckles 30 are arranged opposite each other with their concave sides facing each other. The bottom end of the buckle 30 can be embedded in the groove, and the top end of the buckle 30 is connected to the tension spring 50. Through this technical solution, the bottom of the buckle 30 and the connecting portion 11 can be stably connected, and the buckle 30 and the connecting portion 11 will not separate when the button 40 is not subjected to external force.

[0047] In another specific embodiment:

[0048] The bottom of button 40 is U-shaped, with two tension springs 50 connected to each end of the U-shape. The top of button 40 is a straight rod structure, making button 40 a Y-shaped structure.

[0049] Additionally, a support spring 60 is provided in the middle of the U-shaped button 40, with one end of the support spring 60 connected to the coil bracket 20. The support spring 60 has a tendency to drive the button 40 to move upward (moving away from the latch 30).

[0050] Preferably, the elastic force of the support spring 60 is greater than the sum of the elastic forces of the two tension springs 50.

[0051] In this embodiment, the two tension springs 50 are mainly used to pull the top of the buckle 30 upward to prevent the bottom of the buckle 30 from detaching from the connecting part 11. By setting the support spring 60, the two tension springs 50 can be prevented from pulling the button 40 downward, which would cause the buckle 30 to loosen.

[0052] In another specific embodiment:

[0053] Based on actual usage requirements, when button 40 is pressed down, the tops of the two latches 30 need to rotate downwards, and the bottoms of the two latches 30 need to rotate away from each other.

[0054] Therefore, there is a gap between the vertical plane where the rotating connection shaft between the buckle 30 and the coil bracket 20 is located and the vertical plane where the connection point of the tension spring 50 on the buckle 30 is located.

[0055] Preferably, the distance between the rotating shafts of the two buckles 30 is greater than the distance between the two tension springs 50.

[0056] In this embodiment, when the top of the drive buckle 30 rotates downward, the bottom ends of the two buckles 30 rotate in a direction away from each other, thereby causing the bottom ends of the buckles 30 to disengage from the connecting part 11 of the base 10.

[0057] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
