Description

Technical Field

[0001] This utility model relates to the field of horizontal rocker switch technology, specifically a horizontal rocker switch. Background Technology

[0002] The horizontal rocker switch is shaped like a boat or V. The operating part is tilted at an angle similar to that of a boat. The circuit is turned on and off by manual tossing. The internal structure is a seesaw-like structure, which uses a support point to close or open the contacts.

[0003] In the existing technology, when only vertical space remains on the equipment mounting surface (such as cabinet side panels or wall controllers), vertical installation becomes a necessary choice. However, its operation feel and space efficiency are usually inferior to horizontal installation. Horizontal switches are usually installed on the horizontal panel of the equipment (such as the top surface or desktop), which does not occupy valuable vertical space. For equipment with compact internal structure or limited height (such as desktop appliances and instruments), horizontal layout is more conducive to optimizing the overall design.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a horizontal rocker switch to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A horizontal rocker switch includes a switch housing, a hooked pin connected to the bottom of the switch housing, a rocker button connected to the top of the switch housing, a metal movable piece connected inside the switch housing, a metal contact fixedly connected to the top of the metal movable piece, a slanted opening inside the switch housing, a metal support frame connected inside the slanted opening, a limit slot inside the metal support frame, a through hole on the front surface of the limit slot, a PCB pad on one side of the metal support frame, and a terminal fixedly connected to the side of the switch housing.

[0007] Preferably, the switch housing is made of PA66+30%GF. Two hooked pins are fixedly connected to the bottom of the switch housing. By using a plastic housing made of PA66+30%GF, the PA66 material itself possesses HB-level flame retardant properties (UL94 standard), which can be further improved to V-0 level (self-extinguishing upon removal of flame) by adding flame retardants. This is crucial for the switch housing, effectively preventing the risk of fire caused by short circuits or overloads. PA66 has high tensile strength (up to 80 MPa or more), and after adding 30% glass fiber (GF) reinforcement, its mechanical strength is close to that of metal, capable of withstanding the mechanical stress caused by frequent switching operations. PA66 has a volume resistivity >10¹ in a dry environment.5 With a dielectric strength of >20 kV / mm and Ω·cm, PA66 can effectively isolate high-voltage circuits (such as 220V AC) to avoid leakage or breakdown accidents, and meets the electrical safety standards of switches. PA66 can be efficiently molded into thin-walled complex structures through injection molding, and has good bonding with metal terminals (such as silver-plated brass) and low cost.

[0008] Preferably, the movable metal piece is disposed inside the switch housing, and the movable metal piece is connected to the metal support frame in a lever manner. The movable metal piece can be fixed to the metal support frame by the disposed metal support frame, and two metal support frames are embedded inside the plastic housing, with one end of the support frame being connected to the movable metal piece in a lever manner inside.

[0009] Preferably, a metal column is fixedly connected inside the rocker button, and the metal column is in contact with the metal contact. The rocker button is connected in a "seesaw" manner. A metal column is injection molded in the center of the rocker button as a metal contact. When one end is pressed, the other end tilts up, thus achieving high voltage breakdown insulation.

[0010] Preferably, the terminal is electrically connected to the PCB pad via a power line. The power line is connected inside the through hole. When one side of the switch is pressed, the internal spring is moved and the metal contacts are switched on and off based on the physical lever structure.

[0011] Preferably, the movable metal piece is provided with connecting ears on both sides, and the connecting ears are engaged with the limiting slots. The limiting slots can stably fix the movable metal piece on the metal support frame.

[0012] Preferably, the beveled cover is set in a stepped shape inside the switch housing, and the rocker switch is in contact with the inner surface of the beveled cover. The beveled cover design improves the feel and coverage of pressing the rocker button. The beveled opening just protrudes from the PCB board and is recessed, which can withstand the mechanical stress caused by frequent switching operations.

[0013] The beneficial effects of this utility model are as follows: By using PA66+30%GF material for the switch housing, it not only possesses HB-level flame retardancy (UL94) but can also be easily upgraded to V-0 level (self-extinguishing upon removal of flame) by adding flame retardants. This effectively prevents the risk of fire caused by short circuits, overloads, or external ignition sources, greatly improving the safety of electrical equipment. PA66 material has extremely high volume resistivity (>10¹) in dry environments. 5 With a dielectric strength of Ω·cm and a dielectric strength of >20 kV / mm, it can effectively isolate high-voltage circuits (such as 220V AC), prevent leakage or breakdown accidents, ensure user operation safety, and comply with strict electrical safety standards.

[0014] By incorporating a unique slanted encasing design inside the switch housing, it fits snugly against the surface of the rocker button. This structure provides more stable and smooth support and feedback when the user presses the button, significantly improving the feel and envelopment during pressing. This makes switch operation more comfortable and provides a stronger sense of confirmation. The rocker button operates based on the lever principle (similar to a seesaw), where pressing one end raises the other. This design itself has a clear operating range and a crisp switching feel, allowing users to intuitively perceive changes in the switch status. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] According to an embodiment of the present invention, a horizontal rocker switch is provided. Example

[0019] like Figure 1-4As shown, the horizontal rocker switch according to an embodiment of the present invention includes a switch housing 1, a hook pin 2 connected to the bottom of the switch housing, a rocker button 3 connected to the top of the switch housing 1, a metal movable piece 4 connected inside the switch housing 1, a metal contact 5 fixedly connected to the top of the metal movable piece 4, a beveled cover 6 opened inside the switch housing 1, a metal support frame 7 connected inside the beveled cover 6, a limit slot 8 opened inside the metal support frame 7, a through hole 9 opened on the front surface of the limit slot 8, a PCB pad 10 provided on one side of the metal support frame 7, and a terminal block 11 fixedly connected to the side of the switch housing 1.

[0020] In this embodiment, the switch housing 1 is made of PA66+30%GF. Two hooked pins 2 are fixedly connected to the bottom of the switch housing 1. By using PA66+30%GF as the material for the switch housing 1, the PA66 material itself possesses HB-level flame retardant properties (UL94 standard), which can be further improved to V-0 level (self-extinguishing upon removal of flame) by adding flame retardants. This is crucial for the plastic housing 1, effectively preventing the risk of fire caused by short circuits or overloads. PA66 has high tensile strength (up to 80 MPa or more), and after adding 30% glass fiber (GF) reinforcement, its mechanical strength is close to that of metal, capable of withstanding the mechanical stress caused by frequent switching operations. PA66 has a volume resistivity >10¹ in a dry environment. 5 With a dielectric strength of >20 kV / mm and Ω·cm, PA66 can effectively isolate high-voltage circuits (such as 220V AC) to avoid leakage or breakdown accidents, and meets the electrical safety standards of switches. PA66 can be efficiently molded into thin-walled complex structures through injection molding, and has good bonding with metal terminals (such as silver-plated brass) and low cost.

[0021] In this embodiment, the metal movable piece is disposed inside the switch housing 1 and the metal movable piece 4 is connected to the metal support frame 7 in a lever manner. The metal movable piece 4 can be fixed to the metal support frame by the metal support frame 7. Two metal support frames 7 are embedded inside the plastic housing, and one end of the bracket is connected to the metal movable piece 4 in a lever manner inside.

[0022] In this embodiment, a metal post 301 is fixedly connected inside the rocker button 3. The metal post 301 is in contact with the metal contact 5. The rocker button 3 is connected in a "seesaw" manner. A metal post 301 is injection molded in the center of the rocker button 3 as a metal contact. When one end is pressed, the other end is lifted up to achieve high voltage breakdown insulation.

[0023] In this embodiment, terminal 11 is electrically connected to PCB pad 10 via a power line. The power line is connected inside the through hole 9. When the switch side is pressed via the PCB pad 10, the internal spring is moved and the metal contacts are switched on and off based on the physical lever structure.

[0024] In this embodiment, both sides of the movable metal piece 4 are provided with connecting ears, and the connecting ears are engaged with the limiting slot 8. The limiting slot 8 can stably fix the movable metal piece 4 on the metal support frame 7.

[0025] In this embodiment, the beveled cover 6 is set in a stepped shape inside the switch housing 1, and the rocker switch 3 is attached to the inner surface of the beveled cover 6. The beveled cover 6 improves the feel and coverage of pressing the rocker button. The beveled opening just protrudes from the PCB board and is recessed, which can withstand the mechanical stress caused by frequent switching operations.

[0026] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0027] In practical applications, the core of the switch is a lever structure. The metal movable piece 4 is securely engaged with the limiting slots 8 inside the metal support frame 7 via connecting ears on both sides. The metal support frame 7 is fixedly embedded inside the switch housing 1 (PA66+30%GF). The rocker button 3 is mounted on the top of the switch housing 1, and a metal post 301 is fixedly molded in the center inside. A metal contact 5 (as a fixed contact) is fixed on the top of the metal movable piece 4. When the rocker button 3 is not pressed, the metal post 301 inside it is in a specific contact or separation state with the metal contact 5 on the top of the metal movable piece 4. The electrical connection of the switch is achieved through the hook pin 2 at the bottom and the wiring terminals on the side. The current path is typically as follows: input current flows through a hooked pin 2 / terminal 11 → into the metal support frame 7 → through the metal movable piece 4 → to the metal contact 5 at its top → through contact / separation with the metal post 301 → to the metal post 301 of the rocker button 3 → finally through another metal support frame 7 or connecting structure → to the output of another hooked pin 2 / terminal 11. PCB pads 10 are the soldering fixation and electrical connection points for the switch on the circuit board.

[0028] In summary, the rocker button 3 moves in a rocker motion around its central fulcrum (or approximately the fulcrum area). The pressed end moves downwards, while the other end tilts upwards. The downward-moving button end drives its internal metal column downwards as well. The downward-moving metal column 301 directly presses down on the corresponding end of the metal movable piece 4, which is in contact with it. The metal movable piece 4 itself is a rigid lever, with its fulcrum located at the limiting slot 8 (connecting ear) connected to the metal support frame. When one end of the metal movable piece 4 is pressed down by the metal column 301, according to the lever principle, the other end of the metal movable piece 4 will inevitably tilt upwards. Furthermore, the beveled design inside the switch housing 6 ensures that its inner surface is tightly fitted to the lower surface of the rocker button 3. When the button is pressed, this beveled structure provides stable support and guidance, resulting in even force distribution and smooth stroke during the pressing process, significantly improving the feel and coverage of the operation (i.e., the button is stable and does not wobble when pressed, with clear feedback).

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
