Description

Technical Field

[0001] This utility model relates to the technical field of temperature control switch accessories, specifically to a novel fixing spring and temperature control switch device. Background Technology

[0002] In the past, temperature control switches in power products were generally fixed by spring clips or plastic clips. In actual use, traditional spring clips cannot secure the temperature control switch firmly, and the switch is prone to loosening and falling off. Plastic clips take up a lot of space and can also lead to problems such as lack of installation space. Therefore, there is an urgent need for a new type of device for fixing spring clips and temperature control switches to solve the above problems. Utility Model Content

[0003] In view of this, a new type of fixed spring and temperature control switch device is provided, which is simple in structure, low in cost, robust and reliable, and easy to use.

[0004] A novel fixing spring is used to fix a temperature control switch on a mounting surface. It includes a spring body, a bent baffle extending in the same direction from both sides of the spring body, an elastic bend, and a spring fixing part. The two ends of the elastic bend are respectively connected to the spring body and the spring fixing part. The spring fixing part is fixed to the mounting surface by fasteners. The spring body has a contact inner surface that forms an angle with the elastic bend. The spring body, the bent baffle, and the mounting surface form a slot structure. The temperature control switch is inserted into the slot structure along the inner edge of the bent baffle. The contact inner surface presses against the surface of the temperature control switch under the elastic force of the elastic bend.

[0005] Furthermore, the bent barrier extends perpendicular to the main body of the spring sheet and toward the mounting surface.

[0006] Furthermore, the bending barrier and the elastic bending part are respectively located on three sides that are in contact with the main body of the spring piece, and the temperature control switch is inserted from the side away from the elastic bending part.

[0007] Furthermore, the spacing between the bent barriers is adapted to the width of the temperature control switch, and the length of the bent barriers extending towards the mounting surface is adapted to the thickness of the temperature control switch.

[0008] Furthermore, the inner side of the bent guardrail is provided with an anti-slip structure.

[0009] Furthermore, the spring clip fixing part is provided with fixing holes, and the fastener fixes the spring clip fixing part to the mounting surface through the fixing holes.

[0010] Furthermore, when the temperature control switch is not inserted into the slot structure, the inner contact surface intersects with the fixing surface of the spring fixing part; when the temperature control switch is inserted into the slot structure, the inner contact surface is substantially parallel to the fixing surface of the spring fixing part.

[0011] Furthermore, the main body of the spring sheet, the bending barrier, the elastic bending part, and the spring sheet fixing part are integrally formed metal sheet structures.

[0012] A temperature control switch device includes a circuit board, a heat sink mounted on the circuit board, and a temperature control switch fixed on the heat sink. The temperature control switch is fixed to a mounting surface of the heat sink by the aforementioned novel fixing spring.

[0013] Furthermore, the mounting surface is the heat dissipation interface of the radiator.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] First, the main body of the spring, the bending barrier, and the mounting surface form a slot structure. The temperature control switch can be directly inserted into the slot along the inner edge of the bending barrier. The elastic bending part automatically springs back and presses tightly, so the temperature control switch can be fixed on the mounting surface without tools. When disassembling, the temperature control switch can be removed by simply bending the main body of the spring, making it convenient to use.

[0016] Secondly, the flexible bending part makes the inner contact surface vertically press against the surface of the temperature control switch. The limiting effect of the bending barrier prevents the temperature control switch from falling off vertically, and the anti-slip structure on the inner side of the bending barrier prevents the temperature control switch from slipping off laterally. The overall structure is firm and reliable.

[0017] Third, the new type of fixing spring adopts an integrated metal sheet structure, which is simple in structure, saves installation space significantly, and is suitable for space-constrained scenarios. It only requires metal sheet stamping, which is simple in production process and low in material cost, thus helping to reduce manufacturing costs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3 This illustration shows a novel fixing spring provided by an embodiment of the present invention, used to fix a temperature control switch 1 on a mounting surface 2. It includes a spring body 3, a bent baffle 4 extending in the same direction from both sides of the spring body 3, an elastic bent portion 5, and a spring fixing portion 6. The two ends of the elastic bent portion 5 are respectively connected to the spring body 3 and the spring fixing portion 6. The spring fixing portion 6 is fixed to the mounting surface 2 by fasteners 7. The spring body 3 has a contact inner surface 8, which forms an angle with the elastic bent portion 5. The spring body 3, the bent baffle 4, and the mounting surface 2 form a slot structure. The temperature control switch 1 is inserted into the slot structure along the inner edge of the bent baffle 4. The contact inner surface 8 presses against the surface of the temperature control switch 1 under the elastic force of the elastic bent portion 5.

[0025] Specifically, the bent barrier 4 extends perpendicular to the main body of the spring sheet 3 and toward the mounting surface 2.

[0026] Specifically, the bending barrier 4 and the elastic bending part 5 are located on three sides that are connected to the main body of the spring piece 3, and the temperature control switch 1 is inserted from the side away from the elastic bending part 5.

[0027] Specifically, the spacing between the bends of the baffle 4 is adapted to the width of the temperature control switch 1, and the length of the bends of the baffle 4 extending toward the mounting surface 2 is adapted to the thickness of the temperature control switch 1.

[0028] In some specific embodiments, preferably, the length of the bent barrier 4 extending toward the mounting surface 2 is more than 1 / 2 of the thickness of the temperature control switch 1, while the length of the bent barrier 4 extending toward the mounting surface 2 is less than the thickness of the temperature control switch 1, so as to avoid gaps between the contact inner surface 8 and the surface of the temperature control switch 1, so that the contact inner surface 8 cannot press the surface of the temperature control switch 1 tightly. The spacing between the bends of the barrier 4 is slightly larger than the width of the temperature control switch 1 so that the temperature control switch 1 can be smoothly inserted into the slot.

[0029] Specifically, the inner side of the bent barrier 4 is provided with an anti-slip structure. In some specific embodiments, the inner side of the bent barrier 4 is provided with anti-slip protrusions. Anti-slip protrusions are one embodiment. Anti-slip strips can also be engraved or anti-slip strips can be attached to the inner side of the bent barrier 4.

[0030] Specifically, the spring clip fixing part 6 is provided with a fixing hole 9, and the fastener 7 fixes the spring clip fixing part 6 on the mounting surface 2 through the fixing hole 9.

[0031] Specifically, when the temperature control switch 1 is not inserted into the slot structure, the inner contact surface 8 intersects with the fixing surface of the spring fixing part 6. When the temperature control switch 1 is inserted into the slot structure, the inner contact surface 8 is basically parallel to the fixing surface of the spring fixing part 9.

[0032] Specifically, the spring body 3, the bending barrier 4, the elastic bending part 5, and the spring fixing part 6 are integrally formed metal sheet structures. In some specific embodiments, the spring body 3, the bending barrier 4, the elastic bending part 5, and the spring fixing part 6 can be integrally stamped from a single stainless steel sheet.

[0033] A temperature control switch device includes a circuit board 10, a heat sink 11 mounted on the circuit board 10, and a temperature control switch 1 fixed on the heat sink 11. The temperature control switch 1 is fixed to a mounting surface 2 of the heat sink 11 by the aforementioned novel fixing spring.

[0034] Specifically, the mounting surface 2 is the heat dissipation interface of the heat sink 11.

[0035] In summary, the spring body 3, the bending baffle 4, and the mounting surface 2 form a slot structure. The temperature control switch 1 can be directly inserted into the slot along the inner edge of the bending baffle 4. The elastic bending part 5 automatically springs back and presses, fixing the temperature control switch 1 to the mounting surface 2 without tools. During disassembly, the temperature control switch 1 can be removed by slightly bending the spring body 3, making it convenient to use. At the same time, the elastic bending part 5 makes the inner contact surface 8 vertically press against the surface of the temperature control switch 1, the limiting effect of the bending baffle 4 prevents the temperature control switch 1 from falling vertically, and the anti-slip structure on the inner side of the bending baffle 4 prevents the temperature control switch 1 from slipping laterally. The overall structure is firm and reliable. In addition, the new fixing spring adopts an integrated metal sheet structure, which is simple in structure, significantly saves installation space, and is suitable for space-constrained scenarios. Moreover, it only requires metal sheet stamping, which is simple in production process and low in material cost, thus helping to reduce manufacturing costs.

[0036] It should be noted that this utility model is not limited to the above-described embodiments. Based on the inventive spirit of this utility model, those skilled in the art can make other changes, and these changes made based on the inventive spirit of this utility model should be included within the scope of protection claimed by this utility model.
