Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a lamp holder and a rocker switch with a light. Background Technology

[0002] A rocker switch (also known as a rocker switch or rocker switch) is a common electrical component that controls the on / off state of a circuit by the up-and-down movement of a mechanical rocker. It is widely used in home appliances, automobiles, industrial equipment and other fields.

[0003] Existing rocker switches use integrated indicator lights to indicate their current status. The indicator light is off when the rocker switch is off and illuminates when it is on. However, these indicator lights occupy a significant amount of space inside the rocker switch. For example, Chinese patent CN207149436U discloses a circuit board switch where the circuit board is almost the same size as the top cover, and the circuit board includes vertically pointing LEDs, resulting in a large product size. Another example is Chinese patent CN216288142U, which discloses a backlit rocker switch for vehicles. This uses an additional slot on one side of the base to accommodate the circuit board and LEDs, undoubtedly increasing the length of the rocker switch. Furthermore, the illuminated area is not in the center of the button, resulting in a weak illumination effect. Therefore, existing rocker switches suffer from large indicator light components with low integration, and the connection structure between the indicator light components and the rocker switch is unreasonable, reducing the illumination effect of the indicator light components.

[0004] In view of this, there is an urgent need to design a rocker switch holder with an indicator light and a rocker switch to solve the problem of positioning and installing the indicator light assembly in existing rocker switches. Utility Model Content

[0005] To solve the above problems, this utility model provides a light socket and a rocker switch with a light.

[0006] In a first aspect, this utility model provides a rocker switch holder with an indicator light, comprising a support base and an indicator light circuit board. The support base includes a body, the upper surface of which has a mounting cavity. Limiting platforms are provided on both sides inside the mounting cavity, and limiting slots are provided on the limiting platforms. One side of the limiting slot is an opening. The body has a positioning notch, and a positioning plate is connected within the positioning notch. One end of the positioning plate is connected to the inner wall of the positioning notch, and the other end of the positioning plate has a positioning end that protrudes towards the mounting cavity. The lower surface of the body has an actuating post and a locking post. The actuating post has an actuating cavity that communicates with the limiting slot. The locking post has a locking slot at its end away from the body. The indicator light circuit board includes a circuit board body and plug-in portions located on both sides of the circuit board body. The plug-in portions are connected within the limiting slots, and the positioning end is located on the side of the circuit board body.

[0007] Based on the first aspect, in one possible implementation, the outer periphery of the seat is provided with a blocking edge, and a positioning slot is provided on the outer wall of the blocking edge.

[0008] Based on the first aspect, in one possible implementation, the positioning plate has a separation gap on both sides.

[0009] Based on the first aspect, in one possible implementation, the height by which the positioning end protrudes into the mounting cavity is 1.0 mm to 2.0 mm.

[0010] Based on the first aspect, in one possible implementation, the circuit board body is connected to surface-mount LEDs and surface-mount resistors.

[0011] Based on the first aspect, in one possible implementation, the slot opening is provided with a guide ramp on the side near the positioning end.

[0012] In a second aspect, a rocker switch is provided, comprising a base, a middle seat connected to the base, and a button hinged to the middle seat, and further comprising the aforementioned illuminated rocker switch lamp holder. The support base is connected to the button, and the indicator light circuit board faces the button. Two sets of conductive units are fixedly connected to the base. Each conductive unit includes a support foot and a first stationary contact and a second stationary contact located on both sides of the support foot. A movable contact is movably connected to the support foot. An actuating assembly is connected inside the actuating cavity. The actuating assembly is linked to the movable contact. The movable contact is connected to the first stationary contact or the second stationary contact respectively by the action of the actuating assembly. The indicator light circuit board is electrically connected to the support foot, the first stationary contact, and the second stationary contact respectively.

[0013] Based on the second aspect, in one possible implementation, a partition wall is provided between the conductive units, and a snap-fit ​​pin is provided at the position of the snap-fit ​​post corresponding to the position of the partition wall. During the switching and swinging process of the snap-fit ​​post with the button, the snap-fit ​​slot is linked to the snap-fit ​​pin.

[0014] Based on the second aspect, in one possible implementation, the toggle assembly includes an elastic element and a pressing element, one end of the elastic element abutting against the indicator circuit board, the other end of the elastic element abutting against the pressing element, and the pressing element being linked to the moving contact piece.

[0015] Based on the second aspect, in one possible implementation, the moving contact piece has a positioning recess in the middle, and the two ends of the moving contact piece are respectively connected to moving contacts that are connected to the first stationary contact foot and the second stationary contact foot.

[0016] The carrier base and indicator circuit board of the illuminated rocker switch lamp holder in this technical solution are the actuating and indicating components of the rocker switch. The assembly method of the illuminated rocker switch lamp holder is as follows: place the indicator circuit board on the mounting cavity groove facing the positioning plate, press the indicator circuit board to move the positioning end of the positioning plate away from the mounting cavity groove, and then push the indicator circuit board towards the slot opening until the plug part of the indicator circuit board is connected in the limiting slot. At this time, the positioning end of the positioning plate resets and prevents the indicator circuit board from disengaging from the slot opening.

[0017] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0018] This utility model of a rocker switch holder with an indicator light adopts a vertically fitting structure between the limiting slot and the plug-in part, replacing the traditional horizontal layout of the circuit board. The indicator light circuit board is horizontally housed in the mounting cavity. Through the clamping of both sides of the limiting platform and the lateral limiting of the positioning end, the internal space of the support base is efficiently utilized, allowing the circuit board size to be reduced to be aligned with the center area of ​​the button, significantly reducing the product's vertical height and horizontal width. At the same time, the above positioning structure facilitates the assembly of the indicator light circuit board, helping to improve product assembly efficiency.

[0019] This utility model rocker switch uses the aforementioned illuminated rocker switch holder, which allows the indicator light circuit board to be directly aligned with the button. When the rocker switch is energized, the indicator light circuit board ensures that the illuminated area and the button's operating area are completely overlapped, improving the intuitiveness of human-computer interaction. The illuminated rocker switch holder adopts an integrally injection-molded support structure, and the positioning plate achieves elastic deformation through thin-walled connections, which not only ensures the clearance space when the circuit board is installed, but also provides a reliable limiting function.

[0032] In this embodiment, the positioning plate 15 can be pressed against the lower end face of the base 11, thereby inserting the indicator light circuit board 2 into the limiting slot 131 along the direction of the slot opening 132.

[0033] In this embodiment, the support seat 1 is integrally injection molded, and the positioning plate 15 achieves elastic deformation through thin-wall connection, which not only ensures the clearance space when the indicator light circuit board 2 is installed, but also provides a reliable limiting function.

[0034] In this embodiment, the toggle post 16 is used to drive the conductive sheet to move when the rocker switch is switched, and the locking post 17 is used to put the rocker switch in the intermediate state, that is, the open state. The specific details are explained in Embodiment 2.

[0035] In this embodiment, as shown in the appendix Figure 4 As shown, the outer periphery of the base 11 is provided with a blocking edge 18, and a positioning slot 181 is provided on the outer wall of the blocking edge 18. The positioning slot 181 is used for the connection and positioning of the base 11 with the rocker switch button.

[0038] In this embodiment, as shown in the appendix Figure 5 As shown, a surface-mount LED 23 and a surface-mount resistor 24 are connected on the circuit board body 2. Specifically, the surface-mount LED 23 and the surface-mount resistor 24 are connected in series.

[0040] In this embodiment, the carrier 1 and indicator circuit board 2 of the illuminated rocker switch lamp holder are the actuating and indicating components of the rocker switch. The assembly method of the illuminated rocker switch lamp holder is as follows: place the indicator circuit board 2 on the mounting cavity 12 facing the positioning plate, press the indicator circuit board 2 to move the positioning end 151 of the positioning plate 15 away from the mounting cavity 12, and then push the indicator circuit board 2 toward the slot opening 132 until the insertion part 22 of the indicator circuit board 2 is connected in the limiting slot 131.

At the same time, the above positioning structure facilitates the assembly of the indicator light circuit board and helps to improve the product assembly efficiency.

[0042] Example 2

It also includes a lamp holder as described in Embodiment 1. The support base 1 is connected to the button 5, and the indicator light circuit board 2 faces the button 5. Two sets of conductive units 6 are fixedly connected to the base 3.

A movable contact piece 64 is movably connected to the support foot 61. An actuating assembly 7 is connected within the actuating cavity 161. The actuating assembly 7 is linked to the movable contact piece 64. The movable contact piece 64, under the action of the actuating assembly 7, is connected to either the first stationary contact foot 62 or the second stationary contact foot 63. The indicator light circuit board 2 is electrically connected to the support foot 61, the first stationary contact foot 62, and the second stationary contact foot 63.

[0044] In this embodiment, as shown in the appendix Figure 7 As shown, a partition wall 31 is provided between the conductive units 6. A locking pin 32 is provided at the position of the locking post 17 corresponding to the partition wall 31. During the switching and swinging process of the locking post 17 with the button 5, the locking slot 171 is linked to the locking pin 32. When the button 5 is switched to the middle position, the locking post 17 is positioned on the locking pin 32, so that the moving contact 64 is neither connected to the first stationary contact 62 nor to the second stationary contact 63, that is, in a disconnected state.

[0045] In this embodiment, the rocker switch has three states: In the first state, the support foot 61 is electrically connected to the first stationary contact foot 62 via the moving contact 64; in the second state, the support foot 61 is electrically connected to the second stationary contact foot 63 via the moving contact 64; and in the third state, the moving contact 64 is in an intermediate state, connected only to the support foot 61. In the first and second states, the indicator light circuit board 2 is energized and illuminates.

[0046] In this embodiment, the electrical connection between the indicator light circuit board 2 and the support foot 61, the first stationary contact foot 62 and the second stationary contact foot 63 can be made using a flexible wire or a conductive pin.

[0047] In this embodiment, as shown in the appendix Figure 6 As shown, the toggle assembly 7 includes an elastic element 71 and a pressing element 72. One end of the elastic element 71 abuts against the indicator light circuit board 2, and the other end of the elastic element 71 abuts against the pressing element 72. The pressing element 72 is linked to the moving contact piece 64. The elastic element 71 is a compression spring.

[0048] In this embodiment, as shown in the appendix Figure 9As shown, the moving contact piece 64 has a positioning recess 641 in the middle. The two ends of the moving contact piece 64 are respectively connected to the moving contact 642 connected to the first stationary contact foot 62 and the second stationary contact foot 63. When the rocker switch is in the open state, the pressing member 72 abuts against the positioning recess 641, which improves the reliability of the linkage action of the conductive unit 6 and the toggle assembly 7.

[0049] In this embodiment, the rocker switch uses the aforementioned illuminated rocker switch holder, so that the indicator light circuit board 2 can be directly aligned with the button 5. When the rocker switch is energized, the indicator light circuit board 2 can ensure that the illuminated area and the button 3's operating area are completely overlapped, improving the intuitiveness of human-computer interaction. The illuminated rocker switch holder adopts an integral injection-molded support structure, and the positioning plate 15 achieves elastic deformation through thin-walled connection, which not only ensures the clearance space when the indicator light circuit board 2 is installed, but also provides a reliable limiting function.
