Description

Technical Field

[0001] This utility model belongs to the field of relay technology, and in particular relates to a static spring structure and a relay. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled quantity in an electrical output circuit when the change in the input quantity (excitation quantity) reaches a specified requirement. Relays play roles in circuits such as automatic adjustment, safety protection, and circuit switching.

[0003] An existing relay includes a housing, a stationary reed, a moving reed, a coil, and a heat sink. The stationary reed, the moving reed, and the coil are installed in the housing. One end of the stationary reed extends out of the housing. The heat sink has a flat plate structure and is connected to the part of the stationary reed that extends out of the housing. When the relay is energized, current enters the relay through the stationary reed, activating the coil and causing the contacts on the moving reed to engage with the contacts on the stationary reed, thus completing the circuit. A large amount of heat is generated at the contacts on the stationary and moving reeds. The heat is transferred through the stationary reed to the heat sink, which then conducts the heat to the outside of the housing, achieving heat dissipation.

[0004] However, existing relays have relatively small heat dissipation areas on their heat sinks, resulting in poor heat dissipation performance. Summary of the Invention

[0005] The technical problem to be solved by this utility model is: to address the problem that the heat dissipation area of ​​the heat sink in existing relays is small, resulting in poor heat dissipation effect of the relay, and to provide a static spring structure and relay.

[0006] To solve the above-mentioned technical problems, on the one hand, the present utility model provides a static spring structure, including a static spring sheet and a heat sink, the heat sink including a connecting part and a heat dissipation part, the connecting part being fixed to the static spring sheet, the heat dissipation part being fixedly connected to or integrally formed on the connecting part, and the heat dissipation part and the static spring sheet being spaced apart from each other along a first direction;

[0007] The heat dissipation part includes at least two heat dissipation layers arranged along the first direction, each heat dissipation layer including a plurality of heat dissipation teeth, and adjacent heat dissipation teeth on the same heat dissipation layer are spaced apart.

[0008] Optionally, any two heat dissipation teeth located in the same heat dissipation layer are arranged in parallel.

[0009] Optionally, the spacing between any two adjacent heat dissipation teeth located in the same heat dissipation layer is consistent.

[0010] Optionally, the heat dissipation teeth located in two adjacent heat dissipation layers are arranged alternately along a second direction, wherein the first direction is perpendicular to the second direction.

[0011] Optionally, the thickness of each of the heat dissipation teeth is the same in the first direction.

[0012] Optionally, the ends of each of the heat dissipation teeth that are away from the connecting portion are coplanar.

[0013] Optionally, the connecting portion is L-shaped and includes a heat transfer section and a transition section. The transition section is connected to the stationary spring, and the heat transfer section is connected between the transition section and the heat dissipation portion.

[0014] Optionally, the heat transfer section is attached to the stationary spring on the side facing the stationary spring.

[0015] Optionally, the heat transfer section is connected to the stationary spring screw.

[0016] According to the static spring structure of this utility model embodiment, multiple heat dissipation layers are arranged on the heat dissipation part, and each heat dissipation layer is provided with multiple heat dissipation teeth. Compared with the prior art, the contact area between the heat dissipation component and the air is increased, thereby increasing the heat dissipation area of ​​the heat dissipation component, improving the heat dissipation effect of the heat dissipation component, and thus improving the heat dissipation effect of the relay.

[0017] On the other hand, this utility model embodiment provides a relay including the above-described stationary spring structure. Attached Figure Description

[0020] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] like Figure 1 As shown, an embodiment of the present invention provides a stationary spring structure, including a stationary spring sheet 1 and a heat sink 2. The heat sink 2 includes a connecting part 3 and a heat sink 6. The connecting part 3 is fixed on the stationary spring sheet 1, and the heat sink 6 is fixedly connected to or integrally formed on the connecting part 3. The heat sink 6 and the stationary spring sheet 1 are spaced apart and opposite to each other along a first direction.

[0022] The heat dissipation part 6 includes at least two heat dissipation layers 7 arranged along the first direction, each heat dissipation layer 7 including a plurality of heat dissipation teeth 8, with adjacent heat dissipation teeth 8 on the same heat dissipation layer 7 spaced apart.

[0023] Specifically, the heat dissipation part 6 and the stationary spring 1 are spaced apart and opposite each other along a first direction. The stationary spring 1 has a rectangular plate structure. The first direction refers to the thickness direction of the stationary spring 1. The heat dissipation part 6 and the stationary spring 1 are arranged spaced apart and opposite each other along the thickness direction of the stationary spring 1. The heat dissipation part 6 is provided with multiple heat dissipation layers 7, which are also spaced apart along the first direction. Each heat dissipation layer 7 is provided with multiple heat dissipation teeth 8. Any two heat dissipation teeth 8 connected in the same heat dissipation layer 7 are arranged spaced apart. The heat on the stationary spring 1 is transferred to the heat dissipation part 6 through the connecting part 3. The heat dissipation teeth 8 provided on the heat dissipation part 6 transfer the heat to the air. Compared with the prior art, the arrangement of multiple heat dissipation layers 7 and multiple heat dissipation teeth 8 increases the contact area between the heat dissipation component 2 and the air, thereby increasing the heat dissipation area of ​​the heat dissipation component 2 and improving the heat dissipation effect of the heat dissipation component 2, thereby improving the heat dissipation effect of the relay.

[0024] In one embodiment, any two heat dissipation teeth 8 located in the same heat dissipation layer 7 are arranged in parallel.

[0025] Specifically, the displacement is the same as that of any two heat dissipation teeth 8 of the heat dissipation layer 7, which are arranged in parallel, making the structure of each heat dissipation layer 7 more regular and easier to design and manufacture.

[0026] In one embodiment, the spacing between any two adjacent heat dissipation teeth 8 located in the same heat dissipation layer 7 is consistent. Specifically, the consistent spacing between any two adjacent heat dissipation teeth 8 located in the same heat dissipation layer 7 ensures that the ventilation gap between any two adjacent heat dissipation teeth 8 in the same heat dissipation layer 7 is consistent, thus preventing any one heat dissipation tooth 8 from experiencing a rapid temperature rise.

[0027] In one embodiment, the heat dissipation teeth 8 located on two adjacent heat dissipation layers 7 are alternately arranged along the second direction, where the first direction is perpendicular to the second direction. Specifically, the heat dissipation teeth 8 located on two connected heat dissipation layers 7 are alternately arranged along the second direction, which refers to the width direction of the stationary spring 1 and is perpendicular to the thickness direction (first direction) of the stationary spring 1. This alternating arrangement allows the airflow passing through the ventilation gap between two heat dissipation teeth 8 of a heat dissipation layer 7 to directly hit the heat dissipation teeth 8 of the connected heat dissipation layer 7, thereby accelerating heat dissipation.

[0028] In one embodiment, the thickness of each of the heat dissipation teeth 8 is consistent in the first direction, and the ends of each heat dissipation tooth 8 away from the connecting portion 3 are coplanar. Specifically, the thickness of each heat dissipation tooth 8 is consistent in the first direction, that is, the thickness of each heat dissipation tooth 8 is consistent along the thickness direction of the stationary spring 1, and the ends of each heat dissipation tooth 8 away from the connecting portion 3 are located in the same plane, resulting in a uniform structure that is easy to design and manufacture.

[0029] In one embodiment, the connecting portion 3 is L-shaped and includes a heat transfer section 4 and a transition section 5. The transition section 5 is connected to the stationary spring 1, and the heat transfer section 4 connects the transition section 5 and the heat dissipation portion 6. Specifically, the connecting portion 3 is L-shaped and includes the connected heat transfer section 4 and transition section 5. The heat transfer section 4 is parallel to the stationary spring 1, and the transition section 5 is perpendicular to the stationary spring 1. The side of the heat transfer section 4 facing the stationary spring 1 is in contact with the stationary spring 1, which can increase the contact area between the heat transfer section 4 and the stationary spring 1 and improve the heat transfer efficiency between the stationary spring 1 and the heat transfer section 4. Heat is transferred through the heat transfer section 4 to the transition section 5, and then from the transition section 5 to the heat dissipation portion 6.

[0030] In one embodiment, the heat transfer section 4 is screwed to the stationary spring 1. Specifically, the heat transfer section 4 is provided with a first mounting hole, and the stationary spring 1 is provided with a second mounting hole. By inserting screws through the first mounting hole and the second mounting hole, the heat transfer section 4 is fixed to the stationary spring 1, which facilitates connection.

[0031] The working principle of the static spring structure in this embodiment of the utility model is as follows:

[0032] The heat on the stationary spring 1 is transferred to the transition section 5 via the heat transfer section 4, and then to the heat dissipation teeth 8 on the heat dissipation part 6 via the transition section 5. The gap between two adjacent heat dissipation teeth 8 and the gap between two adjacent heat dissipation layers 7 form an air duct. When the airflow passes through the air duct, it carries away the heat on the heat dissipation teeth 8.

[0033] According to the static spring structure of this utility model embodiment, multiple heat dissipation layers 7 are arranged on the heat dissipation part 6, and each heat dissipation layer 7 is provided with multiple heat dissipation teeth 8. Compared with the prior art, the contact area between the heat dissipation component 2 and the air is increased, thereby increasing the heat dissipation area of ​​the heat dissipation component 2, which can improve the heat dissipation effect of the heat dissipation component 2, and thus improve the heat dissipation effect of the relay.

[0034] In addition, one embodiment of this utility model provides a relay including the above-described stationary spring structure.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
