Description

Technical Field

[0001] The utility model relates to a switch, in particular to a wall switch with a small-angle button. Background Art

[0002] With the increase in the number of electrical appliances, switches are more and more widely used in life, and the switch panels are prominently installed on the wall. With the increasing personalized requirements for home decoration, under the demand for emphasizing the decorative style, new requirements are put forward for the design of wall switches that are often involved. Most existing wall switches are rocker switches. The rocker (usually an integral structure with a swing rod) is usually arranged above the mounting seat, that is, pressing the operation button makes the rocker swing, thereby driving 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 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, and once damaged, it is easy to cause danger; all kinds of components are relatively thick, which wastes materials and the overall shape is not beautiful. Therefore, when particularly 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 obtrusive, the user will hope to obtain an improved solution for this actual demand. That is, the existing wall switch hopes to achieve ultra-thin at the panel (small thickness, small swing angle at the panel), but due to the requirements for power-on stability and performance at the moving contact piece, a certain swing distance is required.

Detailed Embodiments

[0026] The following further describes the embodiments of the present utility model with reference to the drawings:

[0027] As Figure 1 Combined Figures 2 - 5 shown, a wall switch with a small-angle button includes a housing 1 and a panel 2. A conductive sheet 3 is arranged inside the housing 1, and further includes:

[0028] A moving contact piece 4, arranged inside the housing 1, is used to cooperate with the conductive sheet 3 to control the on or off of the circuit;

[0029] A pressing plate 5, arranged inside the housing 1 and above the conductive sheet 3;

[0030] The swing rod 6 is arranged on the pressure plate 5 and extends towards the conductive sheet 3. The swing rod 6 is driven by the panel 2 to swing relative to the pressure plate 5. A guiding groove 61 and a swinging groove 62 are provided on the swing rod 6. The moving contact piece 4 is inserted into the swinging groove 62 and has a swinging space within the swinging groove 62.

[0031] An elastic member 63 is arranged within the guiding groove 61 of the swing rod 6. The elastic member 63 abuts against the moving contact piece 4 and is used to drive the moving contact piece 4 to swing. The beneficial effects of the present utility model are as follows: through the arrangement of the elastic member and the moving contact piece, with a swinging groove provided on the swing rod, the moving contact piece can swing within the swinging groove, enabling the panel to drive the moving contact piece to swing within a large range through the elastic member even when swinging at a small angle, meeting the product performance requirements, thereby preventing the panel from protruding too much outside the wall during use, making the overall product thinner and reducing production costs. The present utility model also has the advantages of simple structure, convenient assembly, reliable operation, overall thin and light product, and long service life. The large swing of the moving contact piece can result in good power-on stability, large pressure, good temperature rise, and good electrical conductivity.

[0032] The swinging groove 62 is arranged in a trumpet shape with one end contracted and the other end open. This provides a larger space for the swinging groove, facilitating the driving of the swinging of the moving contact piece by the elastic member, with a simple structure and convenient and reliable swinging of the moving contact piece.

[0033] The present utility model further includes a swinging foot 64 arranged on the swing rod 6 for driving the moving contact piece 4 to swing. The swinging groove 62 is arranged on the swinging foot 64. The arrangement of the swinging foot drives the swinging of the moving contact piece under the condition of bonding or other special conditions when the moving contact piece is energized, with a simple structure and convenient and reliable transmission.

[0034] The present utility model further includes a connecting piece 7. The connecting piece 7 is arranged within the housing 1 and cooperates with the conductive sheet 3 to achieve circuit conduction. A contact head 41 and a rotating part 42 are provided on the moving contact piece 4. The rotating part 42 of the moving contact piece 4 is arranged on the connecting piece 7 and is driven by the swing rod 6 through the elastic member 63 to rotate relative to the connecting piece 7. Specifically, a guiding block 43 is provided on the moving contact piece 4. The elastic member 63 is sleeved outside the guiding block 43 and abuts against the moving contact piece 4. The guiding block 43 is arranged between the contact head 41 and the rotating part 42. The distance from the guiding block 43 to the contact head 41 is greater than the distance from the guiding block 43 to the contact head 41.

[0035] In this way, the moving contact piece can be arranged vertically with the contact head far from the rotating part. That is, the movement of the guiding part can be amplified by the principle of leverage to make the moving contact part swing. That is, the panel can swing slightly to achieve a large swing amplitude of the moving contact piece, enabling the contact head to reliably connect or disconnect from the conductive sheet. The attached drawings of the present utility model provide a double-control switch, and of course, it can also be applied to a single-control switch.

[0036] The connecting piece 7 is provided with a groove 71, and the rotating part 42 of the moving contact piece 4 is inserted into the groove 71 and driven to swing by the elastic member 63. The groove 71 is arranged in an arc shape or a "V" shape, and the cross-section of the rotating part 42 is in a "V" shape. During actual production, the rotating part can rotate reliably in the groove, and even can have a certain slip in the groove, so that reliable contact or separation of the contact head can be achieved when the panel swings slightly.

[0037] The utility model further includes a driving plate 8. The panel 2 is connected to the swing rod 6 through the driving plate 8 and is used to drive the swing rod 6 to swing. Such a structure enables the panel to reliably drive the swing rod to swing, and the structure is simple.

[0038] The driving plate 8 is hinged to the pressing plate 5 and swingingly cooperates with the pressing plate 5. The panel 2 is covered on the driving plate 8 and is linked with the driving plate 8. There is a relief surface 11 on the housing 1. The relief surface 11 is arranged with the middle part higher and the two ends lower. The panel 2 is in fit with the relief surface 11 when swinging in place. The setting of the relief surface reduces the setting of the upper frame of the housing, reduces the number of components, makes the product thinner and lighter, and is convenient for the panel to rotate and make way.

[0039] The driving plate 8 is provided with a driving block 81, and the driving block 81 is provided with a driving groove 82. The driving groove 82 is engaged with one end of the swing rod 6 and is used to drive the swing rod 6 to swing. Specifically, the cross-section of the other end of the swing rod 6 relative to the swing groove 62 is trapezoidal, and the driving groove 82 is arranged in a "U" shape or a "V" shape. Such a structure enables 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 swinging slightly, meeting the performance requirements of the product.
