Description

Technical Field

[0001] This utility model relates to the field of electrical switch technology, specifically to a rocker switch using a split clamping component. Background Technology

[0002] A rocker switch, also known as a rocker switch, is an electrical switch that switches on and off by pressing a button to cause the contacts to swing.

[0003] Depending on the installation method, the rocker switch housing has different positioning structures. One type of rocker switch achieves its positioning on the mounting panel by setting deformable elastic clamps on both sides of the housing. When this type of rocker switch is installed in place, the elastic clamps are compressed and deformed, and the rocker switch is fixed in the designated position through interference fit, preventing the switch from loosening or falling off due to vibration or external force.

[0004] While using elastic clamps to secure rocker switches offers the advantage of easy installation, the current method of injection molding the elastic clamps and the housing as a single piece is costly due to the injection molding material of the housing. This can cause the elastic clamps to crack in low-temperature environments, leading to the rocker switch easily loosening from its fixed position. Chinese patent CN216957847U discloses a rocker switch with a transverse groove running through the side of the housing. The mounting fastener's snap-fit ​​strip connects to this groove, and elastic limiting pieces at both ends of the snap-fit ​​strip provide lateral restraint for the mounting fastener. Although this patent allows for separate installation of the mounting fastener and the housing, the hook-shaped elastic limiting pieces at both ends of the mounting fastener make it difficult to insert the fastener along the transverse groove during assembly, resulting in significant assembly challenges. Furthermore, it places higher demands on the injection molding process of both the mounting fastener and the housing, increasing production costs.

[0005] In view of this, there is an urgent need to design a rocker switch with a split clamping component to overcome the product defects of existing rocker switches. Summary of the Invention

[0006] To address the aforementioned problems, this utility model provides a rocker switch employing a split clamping component, comprising a base, a housing connected to the base, a conductive component connected to the base, a rocker button movably connected to the base, and a pressure component connected to the rocker button. The conductive component and the pressure component are linked together. The switch also includes clamping components connected to both sides of the housing. External slots are provided on both outer walls of the housing. One end of each external slot is an open end, and the other end is a closed end. A clearance opening is provided on the outer side of the external slot, with limiting portions on both sides of the clearance opening. At least one positioning groove is provided on the inner wall of the external slot. The clamping component includes a plug-in portion, an extension portion connected to the outside of the plug-in portion, and an elastic portion connected to the extension portion. A positioning portion is provided opposite the positioning groove to the plug-in portion. The plug-in portion is connected within the external slot, the extension portion is connected within the clearance opening, and the positioning portion is engaged within the positioning groove.

[0007] The present invention is further configured such that the distance from the top of the positioning part to the top of the insertion part is greater than the height of the external slot.

[0008] The present invention is further provided with a deformation gap between the positioning part and the insertion part, and a guide slope that curves toward the positioning groove on the side of the positioning part away from the deformation gap.

[0009] The present invention is further configured such that a positioning end face is provided on the side of the positioning part facing the opening end, and the positioning end face is adapted to the inner wall of the positioning groove.

[0010] The present invention is further provided with a guide recess on one side of the plug-in portion, and the positioning portion and the guide recess are located on the same side of the plug-in portion.

[0011] The present invention is further configured such that the distance from the guide notch to the opening is shorter than the distance from the positioning part to the opening.

[0012] The present invention is further configured such that the positioning groove is disposed on the upper inner wall or the lower inner wall of the external slot.

[0013] The present invention is further provided with a snap-fit ​​step at the end of the elastic part away from the extension part.

[0014] The present invention is further configured such that the end face of the outer shell away from the base is the switch surface, and the elastic portions on both sides protrude from the switch surface.

[0015] The present invention is further configured such that one or two elastic portions are provided on the same extension portion.

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] The rocker switch in this technical solution adopts a separate design for the clamping component and the housing material, which allows the elastic clamping component to be independently made of low-temperature resistant engineering plastics (such as modified POM or TPU), avoiding the low-temperature embrittlement problem caused by the cost limitation of the housing material in traditional one-piece injection molded parts, and effectively preventing fixation failure caused by low-temperature cracking.

[0018] This technical solution features a rocker switch with an open end and a closed end on one side of the external slot. Combined with the positioning groove on the inner wall of the external slot and the positioning part of the insertion part, the clamping part can be stably connected to the outer shell. When assembling the rocker switch, this technical solution allows for straight insertion along the axial direction of the external slot. Compared with the existing rocker switch insertion method, this provides a larger assembly operation space, higher assembly efficiency, and a more stable clamping connection.

[0019] The rocker switch in this technical solution does not require a complex core-pulling mechanism for its housing injection mold and clamping component injection mold, which significantly reduces the mold manufacturing cost. The housing can continue to use ordinary injection molding materials, while the clamping component uses a high-performance elastomer material, resulting in a significant reduction in overall material cost compared to materials that are resistant to low temperatures. At the same time, the vibration resistance is optimized, and the wedge-shaped fit between the positioning part and the positioning groove forms a reliable mechanical lock.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Combined with appendix Figure 1 To be continued Figure 10 This utility model provides a rocker switch with a split clamping component, comprising a base 1, a housing 2 connected to the base 1, a conductive component 3 connected to the base 1, a rocker button 4 movably connected to the base 1, and a pressing component 5 connected to the rocker button 4. The conductive component 3 and the pressing component 5 are linked together. The switch also includes clamping components 6 connected to both sides of the housing 1. External slots 21 are provided on both outer walls of the housing 2. One end of each external slot 21 is an open end 22, and the other end is a closed end 23. The outer side of the external slot 21 is provided with a clearance opening 24, and the clearance opening 24 is provided with limiting portions 25 on both sides. The inner wall of the external slot 21 is provided with at least one positioning groove 26. The clamping member 6 includes a plug-in portion 61, an extension portion 62 connected to the outside of the plug-in portion 61, and an elastic portion 63 connected to the extension portion 62. The plug-in portion 61 is provided with a positioning portion 64 opposite to the positioning groove 26. The plug-in portion 61 is connected to the external slot 21, the extension portion 62 is connected to the clearance opening 24, and the positioning portion 64 is engaged in the positioning groove 26.

[0032] In this embodiment, the clamping member 6 is installed onto the outer casing 2 by inserting it linearly along the axial direction of the external slot 21. During insertion into the external slot 21, the positioning part 64 is compressed and deformed to a certain extent until it engages with the positioning groove 26. After the positioning part 64 is engaged with the positioning groove 26, it resets and forms a snap-fit ​​with the positioning groove 26, preventing the clamping member 6 from being pulled out of the external slot 21. In this embodiment, the clamping member 6 and the outer casing 2 of the rocker switch are designed as separate parts, allowing the elastic clamping member 6 to be independently made of low-temperature resistant engineering plastics (such as modified POM or TPU). This avoids the low-temperature embrittlement problem caused by the cost limitations of the outer casing material in traditional one-piece injection molded parts, effectively preventing fixation failure due to low-temperature cracking.

[0033] The rocker switch of this technical solution has an external slot 21 with an open end 22 and a closed end 23. Combined with the positioning groove 26 on the inner wall of the external slot 21 and the positioning part 64 on the insertion part 61, the clamping part 6 can be stably connected to the outer shell 2. When assembling the rocker switch of this technical solution, it can be inserted in a straight line along the axial direction of the external slot 21. Compared with the existing rocker switch insertion method, the assembly operation space is larger, the assembly efficiency is higher, and the clamping part connection is more stable.

[0034] In this embodiment, as shown in the appendix Figure 10 As shown, the distance from the top of the positioning part 64 to the top of the insertion part 61 is greater than the height of the external slot 21, so that the positioning part 64 can form an effective snap-fit ​​with the positioning groove 26.

[0035] In this embodiment, as shown in the appendix Figure 6 As shown, a deformation gap 65 is provided between the positioning part 64 and the insertion part 61. The side of the positioning part 64 away from the deformation gap 65 is provided with a guide slope 641 that curves toward the positioning groove 26. The guide slope 641 makes it easier for the clamping member 6 to be inserted into the external slot 21.

[0036] In this embodiment, as shown in the appendix Figure 10 As shown, the positioning part 64 has a positioning end face 642 on the side facing the opening end 22, and the positioning end face 642 is adapted to the inner wall of the positioning groove 26.

[0037] In this embodiment, as shown in the appendix Figure 6As shown, a guide recess 66 is also provided on one side of the insertion part 61. The positioning part 64 and the guide recess 66 are located on the same side of the insertion part 61. During the process of inserting the clamping member 6 into the external slot 21, there is a stroke in which the positioning part 64 and the external slot 21 are interference-fitted. The shrinkage design of the guide recess 66 can reduce the resistance of the clamping member 6 during the insertion and assembly process and improve the assembly efficiency.

[0038] In this embodiment, as shown in the appendix Figure 10 As shown, the distance from the guide notch 66 to the opening end 22 is shorter than the distance from the positioning part 64 to the opening end 22.

[0039] In this embodiment, the positioning groove 26 is disposed on the upper inner wall or lower inner wall of the external slot 21, as shown in the attached figure. Figure 8 and attached Figure 10 As shown, preferably, the positioning groove 26 is disposed on the lower inner wall of the external slot 21, and the positioning groove 26 is connected to the outside. When the clamping member 6 breaks, the positioning part 64 is pressed to pull the clamping member 6 out of the outer shell 2 for easy replacement.

[0040] In this embodiment, the end of the elastic portion 63 away from the extension portion 62 is provided with a snap-fit ​​step 631.

[0041] In this embodiment, the end face of the outer shell 2 away from the base 1 is the switch surface 27, and the elastic portions 63 on both sides protrude from the switch surface 27.

[0042] In this embodiment, one or two elastic portions 63 are provided on the same extension portion 62. In this embodiment, two elastic portions 63 are provided. In other embodiments, only one elastic portion 63 may be provided.

[0043] The rocker switch in this technical solution does not require a complex core-pulling mechanism for its housing injection mold and clamping component injection mold, reducing mold manufacturing costs by 25%-30%. The housing can continue to use ordinary injection molding materials, while the clamping component uses a high-performance elastomer material, resulting in a significant reduction in overall material costs compared to materials resistant to low temperatures. At the same time, the vibration resistance is optimized, and the wedge-shaped fit between the positioning part and the positioning groove forms a reliable mechanical lock.
