Description

TECHNICAL FIELD

[0001] The utility model relates to a wall switch, in particular to a small swing angle wall switch. BACKGROUND

[0002] With the increase of electric appliances, the application of switch in life is more and more, and the panel of the switch is highlighted and arranged on the wall. The personalization requirement of home decoration is higher and higher, and new requirements are put forward for the design of wall switch which is often involved under the demand of emphasizing decoration style. The existing wall switch is mostly a rocker switch, and the rocker (usually integrated with a swing rod) is usually arranged above the mounting seat, that is, the rocker is swung by pressing the operation button to drive the swing rod to swing, so that the swing rod moves to the position. In the existing switch, the moving contact is usually flat and horizontally arranged, and a certain breaking distance is necessary for the product breaking, and the breaking distance is reflected in the swing distance (or angle) of the button. The swing angle of the button or operation part of the common wall switch is relatively large, for example, in the range of + / - 3° or 0~6°. The large swing angle of the button causes the thickness of the part exposed above the wall surface of the switch product to be relatively large, for example, for the swing angle in the range of + / - 3° or 0~6°, the thickness (part protruding above the wall surface) will be 8.8mm and 9.9mm respectively.

[0003] The large thickness of the switch product inevitably causes the part exposed outside the wall after the switch is installed in the wall to occupy a large space, and the switch is easy to be damaged by collision, and once damaged, danger is easy to occur; various components are relatively thick, which wastes materials, and the whole shape is not beautiful. Therefore, in the case of emphasizing the overall flatness of the wall, or for example, in the case where the user does not want the installed switch to be visually prominent, the user will want to obtain an improved solution for such actual needs. That is, the existing wall switch wants to realize ultra-thin (small thickness) at the panel as much as possible (small swing angle at the panel), but the existing wall switch uses the principle of lever to reduce the protruding distance of the panel, but the insertion distance on the panel is usually deep, and the distance from the panel driving swing rod rotating part to the swing rod hinge shaft is usually more than 8mm, so the actual swing angle is still relatively large. SUMMARY

[0031] The swing rod 5 is hinged to the pressing plate 4 through the hinge shaft 51 and is used for driving the movable contact 3 to move.

[0032] The driving block 6 is connected with the swing rod 5 and is used for driving the swing rod 5 to swing.

[0033] The driving block 6 is connected with the swing rod 5 and is used for driving the swing rod 5 to swing.

[0034] The swing rod 5 is arranged above the conductive sheet 11 and is used for driving the movable contact 3 to move.

[0035] The distance from the hinged shaft 51 to the driving block 6 driving the swing lever 5 to rotate is less than 5.5mm. Unlike the existing hinged shaft to the swing lever rotating distance of at least 8mm, the vertical distance from the swing lever hinged shaft to the driving block 6 driving the swing lever 5 to rotate is less than 5.2mm, which can drive the swing lever bottom to rotate in place through the principle of the lever, reliably drive the movable contact to swing in a larger range, so that the panel can be driven by the driving block to move the movable contact to the position even when the panel is swung at a small angle, meet the product performance requirements, thereby avoiding the panel from being too prominent on the wall body when in use, the product is overall thinner, and the production cost is reduced. The distance ensures the rotating distance of the movable contact, and also has a better operation feeling.

[0036] The swing lever 5 is provided with a baffle 54, the baffle 54 forms a guide groove 55 for inserting the driving block 6, the hinged shaft 51 is arranged on the outer side of the baffle 54, and the side of the baffle 54 facing the guide groove 55 is provided with a reinforcing rib. The reinforcing rib increases the strength of the swing lever, so that the product has a long service life. The guide groove formed by the baffle facilitates assembly and reliable operation of the driving block.

[0037] The outer side of the driving block 6 is recessed to form a notch groove 63, the driving block 6 is arranged on the driving plate 7, the panel 2 drives the driving block 6 to swing through the driving plate 7, and the driving plate 7 is hinged to the pressing plate 4 and is in rotating cooperation with the pressing plate 4. The notch groove saves materials, facilitates industrialized production, and reduces costs.

[0038] The driving block 6 and the driving plate 7 are in an integrated structure, the driving block 6 passes through the pressing plate 4 and is connected with the swing lever 5, and the upper surface of the driving plate 7 is provided with a supporting block 71.
