Abstract
Description
Technical Field
[0001] The utility model specifically relates to a wall switch, in particular to a self-resetting wall switch. Background Art
[0002] At present, a wall switch is an electrical switch installed on a wall for use. It is not only a functional home decoration product, but also an electrical component used to connect and disconnect circuits. The seesaw wall switch on the market adopts the principle of tilting up and down or swinging left and right. When the switch is not pressed, the switch panel tilts to one side, and when the switch is pressed, the switch panel tilts to the other side. There is always one side higher than the plane, making the switch surface button uneven. This feature of the seesaw switch will make it easy to accumulate dust on its surface, causing edge jamming, while affecting the visual beauty, and cannot meet the new aesthetic requirements of modern people. Therefore, a press-plate flat wall switch began to appear on the market. Although most of the press-plate flat wall switches can achieve a flat press plate or a small swing angle of the press plate, the structural design of the wall switch is complex, and the movable contact of the switch assembly cannot be realized by a press plate, and the use requirements of a flat wall switch to control multiple circuits cannot be met. In addition, the swing of the movable contact is not stable, and the contact between the movable contact and the static contact is unreliable, so the wall switch has the defect of unreliable working performance. Summary of the invention
[0003] The utility model aims to overcome the defects of the prior art and provide a self-resetting wall switch with simple structure, stable and reliable performance, long service life and good hand feeling.
[0004] To achieve the above object, the utility model adopts a self-resetting wall switch, which includes a base, a gland arranged in the base, a panel arranged on the base, two push plates rotatably arranged on the panel respectively, four groups of contact assemblies arranged in the base respectively, four toggle switches rotatably arranged in the gland and used to drive the four groups of contact assemblies to perform opening and closing, and four groups of self-resetting driving mechanisms arranged between the four toggle switches and the two push plates and distributed in a "field" shape. The self-resetting driving mechanism includes a driving plate rotatably arranged in the panel and cooperating with the push plate, a reset member slidably arranged in the gland, a support member联动配合 with the reset member and used to drive the toggle switch to perform opening and closing actions, and a reset spring arranged between the support member and the gland. A driving rib抵触在 the reset member is arranged at one end of the driving plate, and the linkage cooperation between the reset member and the driving plate is formed. A rib corresponding to the driving plate is arranged on the push plate. The rib passes through the through hole of the panel and抵触在 the driving plate, and the linkage cooperation between the driving plate and the push plate is formed. The contact assembly includes a first wiring terminal arranged in the base, a static contact connected to the first wiring terminal, a second wiring terminal arranged in the base, a moving contact rotatably arranged on the conductive plate of the second wiring terminal, and a driving spring arranged between the moving contact and the toggle switch. A positioning hole is arranged on the conductive plate. One end of the moving contact has a contact part passing through the positioning hole, and a moving contact cooperating with the static contact is arranged on the contact part. Two support swing arms are symmetrically arranged on both sides of the moving contact. The two support swing arms抵触在 both sides of the positioning hole, and the rotational connection cooperation between the two support swing arms and the conductive plate is formed.
[0005] It should be noted that there are some inaccuracies or unclear expressions in the original Chinese text, such as "联动配合" which is not a standard term and is translated as "联动配合" for the time being. It may need to be further clarified and accurately translated according to the specific context.The beneficial effect of the above structure is that the four groups of self-resetting drive mechanisms of the self-resetting wall switch adopt a "field"-shaped structure design, and the two push plates drive the four groups of contact assemblies to perform the opening and closing actions through the four groups of self-resetting drive mechanisms, so as to meet the use requirements of one self-resetting wall switch to control multiple lines. The moving contact is rotatably arranged on the conductive plate through two supporting swing arms, and the swing of the moving contact is more stable, so that the moving contact and the static contact can be reliably contacted, and the working reliability is higher. A driving spring is arranged between the button and the moving contact, and the driving spring can accelerate the movement of the moving contact, which is conducive to speeding up the opening and closing speed of the self-resetting wall switch. When working, the user presses one end of the push plate, and the driving convex strip on the push plate drives the driving plate of one group of the self-resetting drive mechanisms, and the driving plate drives the reset member to move, and the reset member drives the support member to move, and the support member compresses the spring and drives the button to swing, and the button drives the moving contact to move through the driving spring, thereby realizing the closing or opening of the self-resetting wall switch. After the user releases the button, the compressed spring drives the support member and the reset member to reset, the reset member drives the driving plate to reset, and the driving plate drives the button to reset, so that the button can maintain a flat state, which is beneficial to improving the aesthetics and pressing feel of the self-resetting wall switch. Therefore, the self-resetting wall switch has the advantages of simple structure, stable and reliable performance, long service life, and good feel.
[0006] In particular, one side of the two support swing arms is provided with a curved contact surface, which contacts the conductive plate. The two support swing arms of the moving contact contact the conductive plate through the curved contact surface, thereby ensuring that the moving contact can move smoothly, which is beneficial to improving the working reliability of the self-resetting wall switch.
[0007] In particular, the other end of the driving plate has a rotating shaft, and the panel is provided with two rotating shaft positioning grooves matched with the rotating shaft, and the two ends of the rotating shaft are rotatably arranged in the two rotating shaft positioning grooves, and constitute a rotating connection and cooperation between the rotating shaft and the panel. The driving plate is rotatably arranged in the panel through the rotating shaft, thereby ensuring that the driving plate can move flexibly, facilitating the assembly of the driving plate and the panel, and achieving higher assembly efficiency.
[0008] In particular, the other end of the moving contact has a positioning portion, one end of the driving spring is engaged with the positioning portion, and the other end of the driving spring is engaged with the positioning groove of the button. The two ends of the driving spring are respectively engaged with the driving spring and the button, which facilitates the assembly of the button, the driving spring, and the moving contact, and can ensure that the button can reliably drive the moving contact to move, and can accelerate the opening and closing speed of the moving contact.
[0009] In particular, two support arms are symmetrically arranged at the middle of the inner wall of the push plate, and arc-shaped slots are respectively arranged on the two support arms. Two support columns matched with the two support arms are arranged on the panel, and the arc-shaped slots of the two support arms are respectively engaged with the two support columns, and the two support arms are connected and matched with the two support columns. The push plate is rotatably arranged on the panel through the two support arms, so as to facilitate the assembly of the push plate and the panel, and ensure that the push plate can reliably move the panel.
