Description

Technical Field

[0001] This utility model relates to a wall switch, specifically a small-angle wall switch. Background Technology

[0002] With the increasing number of electrical appliances, switches are used more and more in daily life, and their panels are typically mounted prominently on the wall. Common wall switches have relatively large button or operating angles, for example, within the range of + / -3° or 0–6°. This larger button angle results in a correspondingly larger thickness of the outer edge of the switch product protruding above the wall; for example, for common angles within the range of + / -3° or 0–6°, the thickness (the portion protruding above the wall) would be 8.8 mm and 9.9 mm, respectively.

[0003] The considerable thickness of these switch products inevitably results in a significant portion of the switch protruding from the wall after installation, occupying a large space and making the switch susceptible to damage from impacts, potentially posing a safety hazard. The thicker components also waste materials and create an unsightly overall appearance. Therefore, in situations where the overall flatness of the wall is crucial, or where users prefer a visually unobtrusive switch after installation, they will seek improved solutions to address these practical needs. Existing wall switches typically consist of a panel, a pressure plate, and a housing. Switching is achieved by the movement of the panel, which actuates the moving contact. The panel is usually hinged to the housing. In actual installation, a recessed box is typically installed in the wall, the housing is placed inside, and then secured. Mounting holes, usually located on the left and right sides, are provided on the housing, while the panel is pressed and swung from the top and bottom. During installation, the housing may sag after mounting, as screws are turned to ensure a tight fit, leading to a reduced sway angle of the button (panel) and potential switch malfunction. Utility Model Content

[0027] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0028] Depend on Figure 1 and Figure 2-7 As shown, a small-angle wall switch includes a panel 1 and a conductive sheet 2, and further includes:

[0029] The movable contact 3, driven by the panel 1, is used to cooperate with the conductive sheet 2 to control the circuit to be turned on or off;

[0030] The housing 4, the movable contact 3 and the conductive sheet 2 are disposed inside the housing 4; the housing 4 is provided with a pressing side 41 and a mounting side 42, the mounting side 42 is provided with a mounting hole 43 for mounting the housing 4, and the pressing side 41 is located on the other side opposite to the mounting side 42.

[0031] A deformation pressure plate 5 is disposed inside the housing 4 and above the conductive sheet 2. When the housing 4 is installed, the deformation pressure plate 5 protrudes outward under the action of the inner wall of the compression side 41. The panel 1 is hinged to the deformation pressure plate 5 and swings relative to it. The beneficial effect of this invention is that the deformation pressure plate, which protrudes outward under the action of the inner wall of the compression side during housing installation, keeps the panel away from the housing, ensuring the swing angle of the panel and preventing switch failure. This invention also has the advantages of simple structure, convenient assembly, reliable operation, and long service life.

[0032] The deformation pressure plate 5 is positioned with a higher center and lower ends, with the two ends near the extrusion side 41 having a lower horizontal height than the deformation pressure plate 5. The deformation pressure plate 5 is provided with hinge holes 51. This structure causes the deformation pressure plate to arch slightly, facilitating deformation when compressed. Normally, the deformation pressure plate does not deform during normal use. During installation, tightening the housing allows the deformation pressure plate to bulge slightly outwards, and the panel moves accordingly (the panel is hinged to the hinge hole via a drive plate). Therefore, the design allows for a smaller swing angle in the product; the panel swing angle of this product can be designed to be around 2.5°, making the product thinner and lighter.

[0033] This utility model also includes a drive plate 6. The panel 1 is linked to the drive plate 6. The panel 1 is hinged to the deformation pressure plate 5 via the drive plate 6 and is oscillating relative to the housing 4. The drive plate 6 is provided with a drive block 61 for driving the moving contact piece 3. This structure facilitates panel oscillation, panel processing and installation, and has a simple structure.

[0034] The deformation pressure plate 5 protrudes upward to form a hinge seat 52. The drive plate 6 is provided with a hinge shaft 62 that matches the hinge hole 51. The hinge seat 52 is provided with a guide hole 53 to facilitate the installation of the hinge shaft 62. The hinge hole 51 and the mounting hole 43 are on the same cross section. Specifically, the deformation pressure plate 5 is provided with a beveled portion 54 and a flat portion 55. The beveled portion 54 and the flat portion 55 cooperate to form a structure that is high in the middle and low at both ends. The flat portion 55 is on the same cross section as the hinge hole 51. This facilitates the product's installation due to the compression of the shell side (see Appendix). Figure 4The dotted line indicates the deformation of the inner wall of the housing and the deformation direction of the deformation plate. The deformation plate "shrinks" towards the flat part. Due to the setting of the inclined part and the flat part, the flat part protrudes outward (towards the panel mounting direction), so that the product will be slightly raised to avoid product failure after installation.

[0035] The upper or lower surface of the planar portion 55 is recessed inward to form a groove, and the planar portion 55 is provided with a through hole 56. This reduces the strength of the planar portion and facilitates deformation along the planar portion.

[0036] The thickness of the deformation plate 5 is 1.2-1.8mm. This reduces the material used in the deformation plate from the original 2.0mm-2.5mm to about 1.5mm, thus reducing material usage, lowering costs, and facilitating deformation of the deformation plate when it is squeezed.

[0037] The housing 4 is provided with a receiving groove 44 and a receiving cavity 45. The moving contact 3 and the conductive sheet 2 are both disposed in the receiving groove 44. The receiving groove 44 is arranged perpendicular to the pressing side 41. The deformation pressure plate 5 is disposed in the receiving cavity 45 and is engaged with the inner wall of the housing 4. This structure facilitates the installation of the deformation pressure plate and the conductive sheet. A swing rod is usually also provided. The drive plate drives the moving contact to swing and switch via the swing rod.

[0038] A top block 46 is provided on the inner wall of the extrusion side 41. The end of the deformation pressure plate 5 is bent to form a bent edge 57. The top block 46 is positioned towards the receiving cavity 45 and abuts against the bent edge 57 of the deformation pressure plate 5. The bent edge 57 is arranged around the perimeter to form an annular groove 58. The bent edge facilitates the pushing of the top block, resulting in a simple structure. The annular groove helps save material and facilitates the deformation of the deformation pressure plate.

[0039] The extrusion side 41 of the housing 4 is perpendicular to the mounting side 42 of the housing 4. There are two extrusion sides 41 arranged symmetrically. There are multiple top blocks 46, and the top blocks 46 on different extrusion sides 41 are arranged correspondingly. The top blocks 46 are arranged in an "L" shape. This structure makes the deformation pressure plate uniformly stressed and has a simple structure.
