Description

Technical Field

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

[0002] With the increasing use of electrical appliances, switches are increasingly used in our daily lives, and their panels are prominently mounted on the wall. The demand for personalized home decoration is increasing, and the emphasis on decorative style has put forward new requirements for the design of wall switches, which are often used. Existing wall switches are mostly rocker-type switches. The rocker (usually an integrated structure with a rocker arm) is usually located above the mounting base. Pressing the operating button causes the rocker to swing, which in turn drives the rocker arm, which in turn drives the movable contact. During the swinging process, the movable contact engages or separates with the stationary contact to open and close the circuit. In practice, both the movable and stationary contacts are typically made of copper as the conductive material. Some also use silver contacts on the movable contact, but these silver contacts are typically cylindrical, large, heavy, and costly, which affects the movable contact's swing. The silver contacts are usually riveted to the movable contact, which is difficult and expensive to process. The silver contacts can also become loose due to loose rivets, resulting in high temperatures in the switch copper components and reduced product performance. Utility Model Content

DETAILED DESCRIPTION

[0024] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0025] Depend on Figure 1 Combine Figure 2-5 As shown, a wall switch includes a housing 1, wherein a movable contact piece 2 is provided in the housing 1, and further includes:

[0026] The first terminal 3 is provided in the housing 1 and is used for fixing an external wire;

[0027] The connecting piece 4 is provided in the housing 1 and is used to connect to the external wire. The movable contact piece 2 is provided on the connecting piece 4 and is electrically connected to the connecting piece 4.

[0028] The conductive sheet 5 is provided on the first terminal 3 and is used to connect to an external wire. The conductive sheet 5 is provided with a contact member 51, which is provided with a contact portion 52. The contact portion 52 is integrally formed from silver. The movable contact 2 is provided with a movable contact 21, which contacts the contact portion 52 to conduct the circuit. The movable contact 21 is integrally formed from silver and connected to the movable contact 2 by welding. The beneficial effects of the present invention are that the contact portion is provided on the conductive sheet, and the movable contact is provided on the movable contact. The movable contact and the contact portion cooperate to achieve circuit conduction. The movable contact is not easy to loosen, is easy to process, and has better conductivity. The present invention also has the advantages of simple structure, easy assembly, reliable operation, and long service life.

[0029] The movable contact 21 is arranged in a cross shape. The cross-shaped movable contact is convenient for reliable contact with the contact portion to realize circuit conduction, and it saves materials and reduces production costs.

[0030] The contact portion 52 is circular, and the surface of the contact portion 52 is convex toward the moving contact 21. Specifically, the surface of the contact portion is slightly arched and arc-shaped, which facilitates contact with the moving contact and is simple in structure.

[0031] The contact member 51 is formed integrally from copper material and is riveted to the conductive sheet 5. This rational use of the contact member as support results in a simple structure and low production cost.

[0032] The contact member 51 is provided with a groove, and the contact portion 52 is disposed in the groove of the contact member 51 through pier processing. Such a structure facilitates the fixing of the contact portion and facilitates circuit conduction.

[0033] The first terminal block 3 includes a frame 31 having a slot 32 for inserting an external wire. The conductive sheet 5 is inserted into the slot 32 and connected to the external wire. This structure facilitates the fixing of the conductive sheet, is simple in structure, and is easy and reliable to install and fix.

[0034] The frame 31 is provided with a first protrusion 33, which is positioned toward the receiving groove 32. Specifically, the conductive sheet 5 is provided with a second protrusion 53 that mates with the first protrusion 33, which is positioned toward the first protrusion 33. The first and second protrusions cooperate to better secure the external wires, preventing them from shaking and affecting contact performance.

[0035] The connecting piece 4 is provided with a notched groove 41, into which the movable contact piece 2 is inserted and swung relative to the connecting piece 4. Specifically, the notched groove 41 is arcuate or V-shaped, and the movable contact piece 2 is provided with a rotating portion 22 for insertion into the notched groove 41. The rotating portion 22 has a V-shaped cross-section. This allows the movable contact piece to be positioned vertically, allowing the rotating portion to reliably rotate within the notched groove during actual use, and even to allow for a certain amount of slippage within the notched groove, thereby enabling reliable contact or separation of the movable contact with even a slight swing of the panel.

[0036] In the description of the present invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified or limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
