Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, and in particular to a two-way rocker switch with a pre-installed bottom shell. Background Technology

[0002] The inside of a rocker switch is usually equipped with a conductive dome. When the two-way rocker is rotated, the two-way rocker presses the conductive dome, causing the conductive dome to be recessed and contact the two electrical pads below it, thus making the two electrical pads conductive.

[0003] In existing rocker switches, the conductive dome switch is not pre-fixed to other components. Due to its light weight and small size, it is easily affected by vibration, airflow, and other factors during assembly, causing the conductive dome switch to shift. Because the conductive dome switch is prone to shifting, assembly workers need to spend a lot of time and effort adjusting its position to ensure it is correctly aligned with the electrical pads. This not only increases labor costs but also reduces production efficiency, negatively impacting the company's development.

[0004] Therefore, existing rocker switches need to be improved to solve the problem that the conductive dome switch is prone to displacement during the assembly process, resulting in low assembly efficiency.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a pre-installed two-way rocker switch with a bottom shell, which can effectively solve the problem that the conductive dome switch is prone to displacement during the assembly process, resulting in low assembly efficiency.

[0007] To achieve the above objectives, this utility model provides a pre-installed two-way rocker switch with a bottom shell, comprising:

[0008] include:

[0009] A rectangular pre-assembled shell, comprising a rectangular shell surrounding a cavity and a plurality of conductive dome switches fixed to the bottom of the rectangular shell;

[0010] A button panel, which is located within the accommodating cavity;

[0011] A two-way rotating rocker arm is rotatably connected to the rectangular housing and is used to press the button panel downwards when driven.

[0012] The circuit board is located below the rectangular pre-assembled shell, and the circuit board is provided with a pair of conductive pads corresponding to the position of each conductive dome switch.

[0013] The conductive dome switch has an open state where it recovers its upward deformation and detaches from the corresponding two conductive pads when not under pressure, thus disconnecting the two conductive pads; and an on state where it moves downward under the drive of the two-way rotating rocker arm to fit against the corresponding two conductive pads, thus making the two conductive pads conductive.

[0014] Optionally, the conductive dome switch is thermally riveted to the bottom of the rectangular housing.

[0015] Optionally, the bottom of the rectangular housing is provided with a spring positioning groove for the conductive dome to enter and be positioned.

[0016] Optionally, the rectangular housing includes a housing base and a housing cover disposed above the housing base and cooperating with the housing base to surround and form the accommodating cavity.

[0017] Optionally, the housing base is provided with a lower clearance groove corresponding to the position of each pair of conductive pads.

[0018] Optionally, the keypad includes a connecting base plate, and the connecting base plate is provided with a floating pressure block corresponding to the position of each of the lower clearance slots. The floating pressure block is movably connected to the connecting base plate through an elastic arm.

[0019] Optionally, the two sides of the two-way rocker arm are provided with transverse pivots for rotating and inserting into the inner wall of the housing cover.

[0020] Optionally, the two-way rotating rocker arm is provided with a transverse pressure bar for pressing down on the floating pressure block at the position of the floating pressure block, and the housing cover is provided with an upper clearance groove at the position of each transverse pressure bar.

[0021] Optionally, the number of the transverse compression bars is two.

[0022] Optionally, each of the transverse pressure bars is provided with two floating pressure blocks, and a U-shaped flexible pressure block is provided between the transverse pressure bar and the two corresponding floating pressure blocks. The U-shaped flexible pressure block is provided with an upwardly protruding force-bearing protrusion at the position corresponding to the transverse pressure bar.

[0023] The beneficial effects of this utility model are as follows: It provides a bottom shell pre-installed two-way rocker switch. When the rocker switch is not operated, the conductive dome is in an unpressed state due to its elasticity. At this time, the conductive dome returns to its original shape and disengages from the two conductive pads below it, so that the conductive pads are in an open state.

[0024] When the operator rotates the two-way rocker arm, the rocker arm presses down on the button panel, which in turn transmits force to the conductive dome switch, causing the conductive dome switch to move downwards until it contacts the conductive pad below, thus making the conductive pad conductive and completing the circuit closure.

[0025] In this design, the conductive dome is pre-mounted at the bottom of the rectangular housing, corresponding to the conductive pads on the circuit board, rather than being left freely placed. This design reduces the degree of freedom of movement of the conductive dome during assembly, lowering the risk of displacement due to vibration or airflow. Assembly workers do not need to position and fix the conductive dome during assembly, which greatly simplifies the assembly process and reduces assembly time. Furthermore, because the conductive dome's position is pre-fixed, there is no need for fine-tuning of the spring contacts during assembly, thereby reducing the possibility of assembly errors and improving production efficiency.

[0026] Therefore, the pre-installed two-way rocker switch in the bottom shell provided by this utility model can effectively solve the problem that the conductive dome switch is easy to shift during the assembly process, resulting in low assembly efficiency. Attached Figure Description

[0047] See Figure 1 and Figure 2 This utility model provides a pre-installed two-way rocker switch, including a rectangular pre-installed shell 1, a button plate 2, a two-way rotating rocker 3, and a circuit board 4.

[0048] The rectangular pre-assembled shell 1 includes a rectangular shell 101 surrounding a cavity, and a plurality of conductive dome switches 102 fixed to the bottom of the rectangular shell 101; the keypad 2 is located inside the cavity; the two-way rocker arm 3 is rotatably connected to the rectangular shell 101 and is used to press the keypad 2 downward when driven; the circuit board 4 is located below the rectangular pre-assembled shell 1, and the circuit board 4 is provided with a pair of conductive pads corresponding to the position of each conductive dome switch 102.

[0049] The conductive dome switch 102 has an open state where it recovers its upward deformation and detaches from the corresponding two conductive pads when not under pressure, thus disconnecting the two conductive pads; and an on state where it is driven downward by the two-way rotating rocker arm 3 to fit against the corresponding two conductive pads, thus making the two conductive pads conductive.

[0050] The bottom shell pre-installed two-way rocker switch provided in this embodiment, when the rocker switch is not operated, the conductive dome 102 is in an uncompressed state due to the elastic effect. At this time, the conductive dome 102 restores its upward deformation and disengages from the two conductive pads below it, so that the conductive pads are in an open state.

[0051] When the operator rotates the two-way rocker arm 3, the two-way rocker arm 3 presses down on the button plate 2, and then the force is transmitted to the conductive dome 102 through the button plate 2, causing the conductive dome 102 to move downward until it contacts the conductive pad below, thereby making the conductive pad conductive and completing the circuit closure.

[0052] In this design, the conductive dome 102 is pre-mounted on the bottom of the rectangular housing 101, corresponding to the conductive pads on the circuit board 4, rather than being freely placed. This design reduces the degree of freedom of movement of the conductive dome 102 during assembly, lowering the risk of displacement due to vibration or airflow. Assembly workers do not need to position and fix the conductive dome 102 during assembly, which greatly simplifies the assembly steps and reduces assembly time. Furthermore, due to the pre-fixed position of the conductive dome 102, there is no need for fine-tuning of the spring contacts during assembly, thereby reducing the possibility of assembly errors and improving production efficiency.

[0053] Therefore, the pre-installed two-way rocker switch in the bottom shell provided by this utility model can effectively solve the problem that the conductive dome 102 is prone to displacement during the assembly process, resulting in low assembly efficiency.

[0054] Optionally, the conductive dome switch 102 is thermally riveted to the bottom of the rectangular housing 101. Specifically, the bottom of the housing base 1011 is provided with a spring positioning groove 1011b for the conductive dome switch 102 to enter and be positioned, so as to complete the positioning of the conductive dome switch 102.

[0055] In this embodiment, the rectangular housing 101 includes a housing base 1011 and a housing cover 1012 that covers the housing base 1011 and cooperates with the housing base 1011 to form the accommodating cavity. The housing base 1011 and the housing cover 1012 are snap-fit ​​connected. The housing base 1011 is provided with a lower clearance groove 1011a corresponding to the position of each pair of conductive pads.

[0056] The button panel 2 includes a connecting base plate 201. A floating pressure block 202 is provided at each position corresponding to each of the lower clearance grooves 1011a. The floating pressure block 202 is vertically connected to the connecting base plate 201 via an elastic arm 203. When the two-way rotating rocker arm 3 presses down on the floating pressure block 202, the floating pressure block 202 can deform downwards through the corresponding lower clearance groove 1011a and contact the conductive dome 102 directly below the lower clearance groove 1011a, thereby applying downward pressure to the conductive dome 102.

[0057] A U-shaped flexible pressure block 5 is provided between the two-way rotating rocker arm 3 and each of the floating pressure blocks 202. Each of the transverse pressure rods 301 presses down on the corresponding floating pressure block 202 through the U-shaped flexible pressure block 5.

[0058] In the pre-installed two-way rocker switch with a bottom shell, the U-shaped flexible pressure block 5 plays a role in transmitting pressure, buffering, maintaining stability, and adapting to deformation. It effectively transmits the movement and pressure of the two-way rocker arm 3 to the floating pressure block 202, while reducing hard contact during operation, lowering vibration and noise, and improving user comfort and switch lifespan. Furthermore, the U-shaped flexible pressure block 5 prevents the floating pressure block 202 from excessively compressing the conductive dome 102, protecting other sensitive components on the circuit board 4, simplifying the assembly process, and improving the overall reliability and lifespan of the product.

[0059] In this embodiment, the two-way rocker arm 3 is provided with transverse rocker arms 302 on both sides for rotating and inserting into the inner wall of the housing cover 1012. The two-way rocker arm 3 is provided with transverse pressure rods 301 for pressing down on the floating pressure block 202 at the position of the floating pressure block 202, and the housing cover 1012 is provided with an upper clearance groove 1012a at the position of each transverse pressure rod 301.

[0060] The presence of the upper clearance groove 1012a ensures that even with a relatively small overall height of the rectangular housing 101, the lateral pressure rod 301 has sufficient space during rocker arm movement and will not interfere with the housing cover 1012. This helps to further reduce the size of the compact rocker switch and improve the structural compactness.

[0061] Optionally, there are two transverse pressure bars 301, each transverse pressure bar 301 corresponding to two floating pressure blocks 202, and a U-shaped flexible pressure block 5 is provided between the transverse pressure bar 301 and the corresponding two floating pressure blocks 202. The U-shaped flexible pressure block 5 has an upwardly protruding force-bearing protrusion 501 at the position corresponding to the transverse pressure bar 301. After the force-bearing protrusion 501 concentrates the force, the U-shaped flexible pressure block 5 distributes the pressing force downward to the two floating pressure blocks 202.

[0062] See Figure 3 The assembly process of the pre-installed two-way rocker switch with a bottom shell provided in this embodiment is as follows:

[0063] S10: Install the two-way rotating rocker arm 3 and two U-shaped flexible pressure blocks 5 into the housing cover 1012 in sequence;

[0064] S20: The conductive dome switch 102 is hot-riveted to the bottom of the housing base 1011;

[0065] S30: Install the keypad 2 into the housing base 1011;

[0066] S40: Connect the housing base 1011 to the housing cover 1012 via a snap-fit ​​connection;

[0067] S50: The rectangular pre-assembled shell 1 is locked and fixed to the circuit board 4 by fasteners, etc., to complete the assembly; further, the bottom of the shell cover 1012 is provided with a positioning post 1012b that passes through the shell base 1011, and the circuit board 4 is provided with a positioning hole for the positioning post 1012b to be inserted, so that the alignment operation between the rectangular shell 101 and the circuit board 4 can be completed.

[0068] In summary, the pre-installed two-way rocker switch with a bottom shell provided in this embodiment has the following advantages:

[0069] ① Simplified assembly process: Since the conductive dome 102 is pre-installed on the bottom of the rectangular housing 101, the assembly worker does not need to position and fix the conductive dome 102 during the assembly process, which greatly simplifies the assembly steps and reduces the assembly time.

[0070] ② Improve assembly efficiency: The pre-assembled design reduces the degree of freedom of movement of the conductive dome 102 during the assembly process, reduces the risk of displacement due to vibration or airflow, thereby reducing the possibility of assembly errors and improving production efficiency.

[0071] ③ Improve product reliability: The pre-fixing of the conductive dome 102 ensures the consistency of the position of the conductive dome 102 in each switch, which improves the quality stability of the product and extends the service life of the switch.

[0072] ④ Reduce assembly errors: Since there is no need to fine-tune the conductive dome 102, the possibility of human error is reduced, further improving the product qualification rate.

[0073] ⑤ Compact structure: By designing the upper clearance groove 1012a, the rectangular shell 101 can be designed to be smaller, which improves the structural compactness and is conducive to miniaturization design.

[0074] ⑥ Improve user comfort: The use of U-shaped flexible pressure block 5 reduces hard contact during joystick operation, reduces vibration and noise, and improves the user's operating experience.

[0075] ⑦ Low cost: The conductive dome switch 102 is fixed to the bottom of the housing base 1011 by heat riveting. The process is mature and simple, the cost is low, and it is suitable for large-scale production.

[0076] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
