Description

Technical Field

[0001] This utility model relates to the field of relay technology, and more specifically, to a relay with heat dissipation protection function. Background Technology

[0002] A relay, also known as an electric relay, is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit). It is commonly used in automatic control circuits. In fact, it is an "automatic switch" that uses a small current to control a larger current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in the circuit. In daily life, a relay with heat dissipation protection function is often needed.

[0003] Traditional relays mostly lack effective heat dissipation structures. During relay operation, a large amount of heat is generated when the contacts come into contact. If this heat is not dissipated, it can lead to contact damage. At the same time, if the heat inside the relay cannot be dissipated, it will also affect the normal use of other components, reduce the overall lifespan of the relay, and decrease the safety factor during use.

[0004] Therefore, those skilled in the art have provided a relay with heat dissipation protection function to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a relay with heat dissipation protection function, including a housing, and further comprising:

[0006] The base is disposed inside the housing;

[0007] A frame is fixedly installed on the upper surface of the base, and a yoke is provided on the outside of the frame;

[0008] A connecting frame is disposed on the upper surface of the base, and the connecting frame has multiple movable feet inside;

[0009] The stationary feet are symmetrically arranged inside the base.

[0010] Contact assemblies are respectively disposed inside the moving foot and the stationary foot;

[0011] Heat dissipation components are symmetrically arranged on the upper surface of the housing.

[0012] As a further improvement to this technical solution, the contact assembly includes a moving contact disposed inside the moving foot and a stationary contact disposed inside the stationary foot.

[0013] As a further improvement to this technical solution, the heat dissipation component includes heat-conducting plates symmetrically arranged on the upper surface of the housing, the upper surfaces of the two stationary feet respectively contacting the bottom of the two heat-conducting plates, and heat dissipation plates symmetrically arranged on the upper surface of the housing, the upper surfaces of the two heat-conducting plates respectively contacting the bottom of the two heat dissipation plates.

[0014] As a further improvement to this technical solution, the connecting frame is externally fixedly connected with multiple overtravel springs, and the other end of each of the multiple overtravel springs is externally fixedly connected to multiple movable feet.

[0015] As a further improvement to this technical solution, the base is provided with a plurality of protrusions on its exterior, and the inner wall of the outer shell is provided with a plurality of snap-fit ​​grooves for snapping the protrusions.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this type of relay with heat dissipation protection, the contact components and heat dissipation components are designed to ensure the normal operation of the relay. During the operation of the relay, the contact components close together, generating heat. The heat dissipation components effectively dissipate this heat, thereby reducing the temperature between the contacts and preventing damage due to overheating. Simultaneously, the heat dissipation components effectively dissipate heat from within the relay, protecting the internal components, extending the relay's lifespan, and improving its safety and practicality during use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1 - Figure 4 As shown, this embodiment provides a relay with heat dissipation protection function, including a housing 1, and further including:

[0026] Base 2 is located inside the outer casing 1;

[0027] The frame 3 is fixedly installed on the upper surface of the base 2, and the frame 3 is provided with a yoke 4 on the outside;

[0028] A connecting frame 8 is provided on the upper surface of the base 2, and multiple movable feet 9 are provided inside the connecting frame 8;

[0029] Static feet 5 are symmetrically arranged inside the base 2;

[0030] The contact components are respectively located inside the moving foot 9 and the stationary foot 5;

[0031] Heat dissipation components are symmetrically arranged on the upper surface of the outer casing 1.

[0032] The working principle described above is as follows: The contact components enable the relay to function normally. During operation, the contact components close together, generating heat. The heat dissipation components effectively dissipate this heat, reducing contact temperature and preventing damage from overheating. Simultaneously, the heat is effectively dissipated from the relay's internal components, protecting them, extending its lifespan, and enhancing its safety and usability.

[0033] In order for the relay to function properly, the contact assembly includes a moving contact 11 located inside the moving foot 9 and a stationary contact 10 located inside the stationary foot 5. The arrangement of the moving contact 11 and the stationary contact 10 enables the relay to function properly, thus facilitating its use by the user.

[0034] Considering that a large amount of heat is generated during the operation of the relay, the heat dissipation component includes heat-conducting plates 6 symmetrically arranged on the upper surface of the housing 1. The upper surfaces of the two stationary feet 5 are in contact with the bottoms of the two heat-conducting plates 6 respectively. Heat dissipation plates 7 are symmetrically arranged on the upper surface of the housing 1, and the upper surfaces of the two heat-conducting plates 6 are in contact with the bottoms of the two heat dissipation plates 7 respectively. During the operation of the relay, the contacts will come into contact with each other. After the contacts have been in contact for a long time, a large amount of heat will be generated. At this time, the heat-conducting plates 6 can effectively conduct the heat out and transfer it to the interior of the heat dissipation plates 7, and then dissipate the heat through the heat dissipation plates 7. This can effectively reduce the temperature between the contacts and effectively dissipate heat inside the relay, effectively extending the service life of the relay, improving the practicality of the relay and the safety factor during use.

[0035] To prevent the movable foot 9 from overtraveling, multiple overtravel springs 13 are fixedly connected to the external of the connecting bracket 8. The other end of the multiple overtravel springs 13 is fixedly connected to the external of the multiple movable feet 9. By setting the overtravel springs 13, the overtravel of the movable foot 9 can be effectively prevented, and the overall stability of the relay during operation can be effectively improved.

[0036] To facilitate assembly between the housing 1 and the base 2, the base 2 is provided with multiple protrusions 12 on its exterior, and the inner wall of the housing 1 is provided with multiple snap-fit ​​grooves for engaging the protrusions 12. The engagement of the protrusions 12 and the snap-fit ​​grooves on the inner wall of the housing 1 facilitates assembly between the base 2 and the housing 1, thereby effectively improving the overall production efficiency of the relay.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
