Description

Technical Field

[0001] The utility model relates to the technical field of hardware and electrical equipment, in particular to the technical field of switches, and specifically refers to a small-angle switch structure with a moving contact. Background Art

[0002] A wall switch is an electrical switch installed on a wall to connect and disconnect circuits and control the on and off of lights. Currently, there are two types of switch devices on the market, depending on their thickness and internal structure: 1. The button is directly connected to its internal swing structure, and the rotation angle of the button is consistent with the swing angle of the swing structure. Under this structure, the switch device requires a large thickness both inside and outside the wall, limiting the appearance of the switch device. 2. A lever is set on each side of the swing structure. The swing structure is operated by pressing the levers on both sides with the button, so that the button can rotate at a smaller angle to drive the swing structure to swing at a larger angle, reducing the thickness of the switch device. This design structure requires a large number of production and assembly parts, and its reliability is reduced.

[0003] Therefore, there is a need to optimize and improve the structure of wall switches, such as push button switches. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a small-angle switch structure with a moving contact that is simple in structure, stable and reliable, and has a wide range of applications.

[0005] In order to achieve the above-mentioned purpose, the structure of the small-angle switch with a moving contact of the present invention is as follows:

[0006] The small-angle switch structure with a moving contact has the following main features: the structure includes a switch button, a fixed plate, a metal base plate, a lower shell, a driving member, a spring, an incoming conductor, a movable contact piece, an outgoing conductor, a saddle-shaped terminal and a swinging member; the saddle-shaped terminal, the outgoing conductor, the movable contact piece, the swinging member, the spring and the incoming conductor are assembled in the lower shell in sequence; the lower shell is fixed to the fixed plate by clamping claws and buckles on both sides; the lower shell is arranged on the metal base plate; the switch button is clamped and fixed to the driving member; the driving member moves up and down following the switch button; the driving member is clamped and fixed to the fixed plate; the spring is arranged in the inner cavity on the upper side of the swinging member; the swinging member is connected to the driving member; and the spring is freely connected to one end of the movable contact piece.

[0007] Preferably, the fixing plate is provided with a first rotating shaft, the driving member is rotatably connected to the shaft hole of the fixing plate, and the driving member is supported to rotate around the first rotating shaft.

[0008] Preferably, the lower shell is provided with a second rotation axis, the swing member is rotationally connected to the shaft hole of the lower shell, and the swing member is supported to rotate around the second rotation axis.

[0009] Preferably, the U-shaped fork end of the driving member is connected to the lower end of the rotating shaft of the swing member in a sliding manner.

[0010] Preferably, an inner cavity is provided on the upper side of the swinging member, and the spring is provided in the inner cavity of the swinging member.

[0011] Preferably, an Ω-shaped fork is provided at the upper end of the swinging member.

[0012] The present invention employs a low-angle switch structure with a movable contact. The rotation angle of the driving member is much smaller than that of the swinging member, enabling the switch function to be achieved by swinging the switch button at a small angle. This reduces the overall height of the panel switch while maintaining the same functionality, thereby improving the overall aesthetics of the panel switch and meeting the user's personalized decorative requirements. The present invention's rocker mechanism for the movable contact and low-angle switch reduce the noise generated by the hard collision of the contacts during the toggle of the switch lever, resulting in a simple structure and convenient and practical use.

[0054] As a preferred embodiment of the present invention, the spring 60 drives the movable contact piece 83 to move, so that the movable contact piece 83 contacts and separates with the moving contact and the static contact on the outgoing conductive member 82. Under the pressure of the spring 60, the movable contact piece 83 can be kept in the contact and separation states.

[0055] In the specific implementation of the utility model, a rocker mechanism of a moving contact and a small-angle switch are provided, which can achieve ingenious design, stability and reliability, long service life and wide application range. The rocker mechanism reduces noise during use and has a simple structure, convenience and practicality.

[0056] A swing rod structure of a movable contact includes a switch button 10, a fixed plate 20, a driving member 50, a swing member 90, a spring 60, a movable contact piece 83, an outlet conductive member 82, a lower shell 40 and a metal bottom plate 30.

[0057] The driving member 50 is connected to the switch button 10 and can be pressed up and down along with the switch button 10 to realize the conduction or disconnection of the switch circuit;

[0058] The fixed plate 20 is provided with a first rotating shaft, and the driving member 50 is rotatably connected to the shaft hole of the fixed plate 20; the lower shell 40 is provided with a second rotating shaft, and the swing member 90 is rotatably connected to the shaft hole of the lower shell 40.

[0059] When the switch button 10 is pressed, the driving member 50 rotates around the first rotation axis, and the swing member 90 rotates around the second rotation axis. The U-shaped fork end of the driving member 50 is connected to the lower end of the rotation axis of the swing member 90 in a sliding manner, ensuring that the driving member 50 drives the swing member 90 to rotate;

[0060] An inner cavity is provided on the upper side of the swing member 90, and a spring 60 is provided in the inner cavity. The swing member 90 is driven to rotate by the driving member 50, thereby driving the spring 60 to twist back and forth. The spring 60 is freely connected to one end of the movable contact piece 83 to drive the movable contact piece 83 to move, so that the movable contact piece 83 contacts and separates with the movable contact and static contact on the outgoing conductive member 82, and the movable contact piece 83 can be kept in the contact and separation states under the pressure of the spring 60; the upper end of the swing member 90 is provided with an Ω-shaped fork, which can forcibly remove the contact sticking phenomenon caused by large current to ensure the stability of product performance.

[0061] Figure 1 This is the exploded view of the small angle switch. Figure 1 It includes a switch button 10, which is suitable for being pressed and rotated by the user; a metal base plate 30, which enhances the installation strength; a fixed plate 20, a lower shell 40, a driving member 50, a swinging member 90, a spring 60, an incoming conductive member 70, a movable contact piece 83, an outgoing conductive member 82 and a saddle-shaped terminal 81. The saddle-shaped terminal 81, the outgoing conductive member 82, the swinging member 90, the movable contact piece 83, the spring 60, and the incoming conductive member 70 are assembled in the lower shell 40 in sequence, and then the lower shell 40 with the assembled conductive members is fixed to the fixed plate 20 by the claws and buckles on both sides, the driving member 50 is clamped and fixed to the fixed plate 20, and the switch button 10 is clamped and fixed to the driving member 50. Finally, the assembled overall product is clamped to the metal base plate 30 to assemble into a small-angle sliding mechanism switch.

[0062] Figures 2 to 4 It is a simplified schematic diagram of the small-angle switch, a driving cross-sectional diagram of the small-angle switch swing member 90 and a cross-sectional diagram of the small-angle switch state. The principle is as follows: the user presses the switch button 10, the switch button 10 is connected to the driving member 50 and rotates around the first rotation axis with a rotation angle of ±1.5°. The U-shaped opening 53 at the lower end of the driving member 50 slides the 906 of the rocker 90, thereby driving the swing member 90 to rotate around the second rotation axis with a rotation angle of ±6°. The swing member 90 drives the spring 60 to twist back and forth. The spring 60 is freely connected to one end of the movable contact piece 83 to drive the movable contact piece 83 to move, so that the movable contact piece 83 contacts and separates with the moving contact and the static contact on the outgoing conductive member 82, and the pressure generated by the spring 60 can keep the movable contact piece 83 in the contact and separation states, so as to better keep the switch panel 1 in the open and closed states, and realize the new operation mode structure of switching the switch between the closed state and the open state; in addition, the upper end of the swing member 90 is provided with an Ω-shaped fork, which can forcibly remove the contact sticking phenomenon caused by large current to ensure the stability of product performance. Because the switch panel rotates at a ±1.5° angle, its travel is minimal, minimizing the noise of the switch panel striking the plastic base and the clashing of the contacts on the movable conductive member and the contacts on the outgoing conductive member 82. This reduces noise, providing a better user experience, simple operation, and a compact structure for ease of use. Furthermore, the thickness of the switch frame protruding from the wall is reduced from 8 to 10 mm to 6 to 8 mm, which falls short of meeting users' increasing demands for aesthetically pleasing products.

[0063] like Figure 4 As shown, the first rotating shaft fulcrum 01 mainly functions to drive the rotating shaft of the component to rotate around it; the V-shaped groove 02 of the incoming conductive component mainly functions to enable the movable contact piece to swing back and forth with the top of the V-shaped groove as the fulcrum, and also ensures that the movable contact piece and the incoming copper component are in full contact, thereby improving conductivity; the second rotating shaft hole 03 mainly functions to allow the rotating shaft of the swinging component to rotate around it.

[0064] like Figure 6 As shown, the square card hole 51 is mainly used in that a card hook is designed on the seesaw, which is fixed by the square card hole; the thrust rod 52 is mainly used in that the long arm makes the swing head on the swing member swing a certain distance, thereby realizing the swing member to swing a certain angle; the U-shaped fork 53 is mainly used in that the end of the U-shaped fork is connected to the swing head in a sliding manner to drive the swing head to swing.

[0065] like Figure 7As shown, the second rotating shaft 901 is the rotating shaft of the swing member, and its main function is to rotate the swing member around it; the swing head 902, whose main function is to connect the end of the U-shaped fork with the swing head in a sliding manner, is driven by the U-shaped fork of the driving member; the Ω-shaped fork 903, whose main function is to force the moving contact piece to force the protrusion to separate the moving and static contacts; the inner cavity 905 of the swing member, whose main function is to accommodate the spring, allowing the spring to twist and swing in the cavity to realize the swing of the movable contact piece; the rocker rod 906, whose main function is to connect the second rotating shaft and the swing head.

[0066] like Figure 8 As shown, the forced-pushing protrusion 831 on the moving contact piece is mainly used to separate the moving and static contacts when the current is large and the moving and static contacts are prone to sticking together. The Ω-shaped fork of the swinging member is used to forcibly drive the forced-pushing protrusion of the moving contact piece; the driven protrusion 832 on the moving contact piece is mainly used to freely connect the inner diameter of the spring with the driven protrusion on the moving contact piece, and the spring drives the moving contact piece to swing; the waist-shaped hole 833 is mainly used to reduce the rigidity of the movable contact piece and reduce the noise generated by the hard collision of the contacts.

[0067] This utility model features a rocker mechanism for a movable contact and a small-angle switch that allows the switch's rocker to swing at an angle of ≤1.5°, thereby reducing the sound of the rocker hitting the floor and the contact clashing. It also reduces the thickness of the switch protruding from the wall, meeting users' increasing demands for product aesthetics. The structure is simple, convenient, and practical.

In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0072] The low-angle switch structure with a movable contact of the present invention utilizes a drive member 50 with a rotation angle much smaller than that of the swing member 90, thereby enabling the switch function to be achieved through a small-angle swing of the switch button 10. This reduces the overall height of the panel switch while maintaining the same functionality, thereby improving the overall aesthetics of the panel switch and satisfying the user's personalized decorative requirements. The rocker mechanism of the movable contact and the low-angle switch of the present invention can reduce the noise generated by the hard collision of the contacts during the toggle of the switch lever, and the structure is simple, convenient and practical.
