Description

Technical Field

[0001] The utility model relates to a switch, in particular to a wall switch. Background Art

[0002] With the increase in the number of electrical appliances, switches are increasingly used in life, and the switch panels are prominently installed on the wall. With the increasing personalized requirements for home decoration and the emphasis on decorative styles, new requirements have been put forward for the design of wall switches that are often involved. Most existing wall switches are toggle switches. The toggle (usually an integral structure with a swing rod) is usually arranged above the mounting base, that is, by pressing the operation button, the toggle swings to drive the swing rod to swing. In order to make the swing rod move in place. In the existing switch, the moving contact is usually arranged horizontally in a flat shape. In order to ensure a certain breaking distance for the product to be disconnected, and this breaking distance is reflected in the swing distance (or angle) of the button. The swing angle of the button or the operating part of the common wall switch is relatively large, for example, within the range of + / - 3° or 0 - 6°. The relatively large button swing angle causes the thickness of the part of the outer edge of the switch product exposed above the wall surface to be correspondingly large. For example, for the swing angles within the common range of + / - 3° or 0 - 6°, the thickness (the part protruding above the wall surface) will be 8.8 mm and 9.9 mm respectively.

[0003] This relatively large thickness of the switch product inevitably causes the part exposed outside the wall to occupy a large space after the switch is installed in the wall, and at the same time, the switch is easily damaged by collision. Once damaged, it is prone to danger; all kinds of components are relatively thick, which wastes materials and the overall shape is not beautiful. Therefore, in the case of particularly emphasizing the overall flatness of the wall, or for example, when the user does not want the installed switch to be visually obtrusive, the user will hope to obtain an improved solution for this actual need. In addition, a face frame is usually provided on the existing housing, and the panel is arranged to swing on the panel, which makes the product as a whole thicker and affects the swing of the panel. The existing panel usually directly drives the swing rod to swing, the panel structure is complex, and the panel usually needs to have an aesthetic function. Therefore, the existing panel and its driving part have problems such as complex structure, difficult processing, high production cost, and unreliable transmission. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further describes the embodiments of the present utility model with reference to the drawings:

[0028] As Figure 1 Combined with Figures 2 - 7 shown, a wall switch includes a housing 1 and a panel 2. A moving contact piece 3 and a conductive sheet 4 are provided inside the housing 1, and further includes:

[0029] A pressing plate 5, which is provided inside the housing 1 and above the conductive sheet 4;

[0030] The swing rod 6 is provided on the pressure plate 5 and is used to drive the movable contact piece 3 to swing;

[0031] The driving plate 7, the panel 2 is connected to the driving plate 7; the driving plate 7 is provided with a driving block 71, the driving block 71 is provided with a driving slot 72, the driving slot 72 is inserted into one end of the swing rod 6 and is used to drive the swing rod 6 to swing relative to the pressure plate 5. The beneficial effect of the utility model is that a driving plate is provided, and the swing rod can be reliably driven to swing through the driving plate, the structure is simple, and the transmission is convenient and reliable; at the same time, the structure of the panel is simplified, the production difficulty and cost are reduced, so that the panel can swing at a small angle to meet the transmission and product performance requirements. The utility model also has the advantages of simple structure, convenient assembly, reliable action, overall lightness and thinness of the product, and long service life.

[0032] The swing rod can drive the moving contact piece to swing. Of course, in fact, the swing rod can drive the moving contact piece to swing through a spring, so that even when the panel swings at a small angle, the elastic member (spring) can drive the moving contact piece to swing in a larger range, meeting the product performance requirements, thereby avoiding the panel protruding too much outside the wall when in use, making the product thinner as a whole, and reducing production costs. The large swing of the moving contact piece can make the power-on stability good, the pressure high, the temperature rise good, and the conductivity good.

[0033] The swing rod 6 is provided with a transmission part 61, and the driving groove 72 is in a "U" or "V" shape and is arranged outside the transmission part 61 and is used to drive the swing rod 6 to swing. Specifically, the cross section of the transmission part 61 is arranged in a trapezoidal shape, and the swing rod 6 is hinged on the pressing plate 5 and is swingably connected to the pressing plate 5. Such a structure allows the swing rod to have a certain relative slip with the driving plate when the driving plate rotates, so that the panel can drive the moving contact piece to swing greatly when the panel swings slightly, meeting the product performance requirements.

[0034] The panel 2 and the drive plate 7 are linked by the hook 21 and the slot 73. The hook and the slot make the panel connection convenient and reliable, so that the panel and the drive plate can be made of different materials to reduce costs, and can be manufactured separately to reduce processing difficulty.

[0035] The driving plate 7 is provided with a positioning groove 74, and the panel 2 is provided with a positioning block 22 adapted to the positioning groove 74. Specifically, a guide block 75 is provided in the positioning groove 74, and the guide block 75 is provided with an inclined surface 751 in the insertion direction toward the positioning block 22. Such a structure facilitates the connection between the panel and the driving plate, has a simple structure, and the panel and the driving plate can be quickly disassembled and assembled, and is convenient for use with the housing and the pressure plate.

[0036] The described drive plate 7 is hinged to the pressure plate 5 and is swing - fitted with the pressure plate 5. The panel 2 is placed on the drive plate 7 and is linked with the drive plate 7. Specifically, a relief surface 11 is provided on the housing 1. The relief surface 11 is set to be high in the middle and low at both ends. When the panel 2 swings into place, it fits with the relief surface 11. The setting of the relief surface reduces the setting of the upper frame of the housing, reduces the number of parts, makes the product thinner and lighter, and is convenient for the panel to rotate and make way.

[0037] A groove 12 and a receiving groove 13 are provided on the housing 1. The conductive sheet 4 is arranged in the receiving groove 13. The pressure plate 5 is arranged in the groove 12 and covers the receiving groove 13. A limiting block 14 is arranged on the inner wall of the housing 1. An elastic block 51 is provided on the pressure plate 5. The elastic block 51 is arranged below the limiting block 14 for limiting the pressure plate 5. Such a structure is convenient for the installation of the pressure plate. The pressure plate is reliably limited, easy to disassemble and assemble, convenient for maintenance, does not need to be fixed by additional structures such as bolts, and has a simple structure. The setting of the receiving groove makes the product safer, avoids the exposure of the conductive sheet, and has a long service life.

[0038] The upper surface of the drive plate 7 is provided with a top block 76 and a hole groove 77. The hole groove 77 is arranged above the drive block 71. The setting of the hole groove reduces the material used in the product, increases the strength at the drive block, has a simple structure, low production cost. The setting of the top block is convenient for cooperation with the panel, avoids over - movement, and has a long service life.
