Description

Technical Field

[0001] The utility model relates to the technical field of wall switches, in particular to a wall switch with a novel switch springboard. Background Art

[0002] The springboard switch and the swing plate switch are two common types of wall switches, and these two switches have their own disadvantages. The disadvantage of the springboard switch is that the static contact of the switch is arranged between the opposite terminals and has low stability. In the process of contact between the moving contact of the springboard and the static contact, the terminal block on which the static contact is installed will swing, which makes the overall pressing feel of the switch poor and the feedback feel after the switch is pressed is poor. The disadvantage of the swing plate switch is that the connection between the swing plate and the terminal block is unstable, and a spring needs to be added between the swing member and the swing plate to enable the swing plate to be pressed against the terminal block. In addition, since the bottom wall of the swing plate switch has two protruding ends connected to the terminal block, the contact area between the two is small, which causes the temperature to rise during use, affecting the overall service life.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model will be further described below in conjunction with the accompanying drawings of the specification.

[0028] The utility model provides the following technical solutions:

[0029] As attached Figure 1-10 As shown, the utility model discloses a wall switch with a novel switch springboard, comprising a switch box 1 and a switch panel 2, wherein a swinging member 3, an integrated springboard 4 and a wiring unit 5 are arranged in the switch box 1, wherein the wiring unit 5 is arranged on both sides of the integrated springboard 4, wherein one end of the wiring unit 5 extends to the bottom of the integrated springboard 4 and is connected to the integrated springboard 4, wherein the integrated springboard 4 has a springboard portion 6 and a swinging piece portion 7, wherein both ends of the swinging member 3 are respectively connected to the switch panel 2 and the springboard portion 6, wherein the switch panel 2 is pressed to drive the integrated springboard 4 to swing on the wiring unit 5 through the swinging member 3, wherein the swinging piece portion 7 of the integrated springboard 4 realizes circuit on-off control with the wiring unit 5 during the swinging process. Specifically, in the present design, the switch springboard and the switch swing piece in the prior art are set as an integrated springboard 4 that is integrally formed, the springboard portion 6 of the integrated springboard 4 can contact the swing member 3 and swing under the drive of the swing member 3, and the springboard portion 6 can drive the swing piece to swing during the swinging process so that the moving contact 13 on the swing piece portion 7 can contact or disconnect with the static contact on the wiring unit 5, thereby achieving the purpose of controlling the on-off of the circuit; compared with the traditional springboard switch, the present design achieves circuit on-off control through the swing of the swing piece portion 7, and in the present design, the static contacts are arranged on the upper part of both sides of the moving contact, such a structure can enhance the pressing feel and improve the user experience; and compared with the traditional swing piece switch, the present design adopts line contact between the springboard portion 6 and the wiring unit 5, thereby increasing the contact area between the two, reducing temperature rise, and extending the service life of the integrated springboard 4.

[0030] Specifically, the springboard 6 and the swing plate 7 of the integrated springboard 4 can be formed by stamping, welding or riveting. The above components described in the utility model are all formed by stamping technology.

[0031] Further, such as Figure 2-9 As shown, one end of the springboard portion 6 extends to form a swing piece connection portion 8, the wiring unit 5 has a static contact end 9, and the swing piece portion 7 is formed by the swing piece connection portion 8 extending toward the static contact end 9. The springboard portion 6, the swing piece connection portion 8 and the swing piece portion 7 are all integrally formed structures. Specifically, the swing piece portion 7 is formed on either side of one end of the springboard portion 6, and the swing piece connection portion 8 between the swing piece portion 7 and the springboard portion 6 can extend the distance of the springboard portion 6, thereby increasing the contact area between the springboard portion 6 and the springboard support end 19 of the main terminal 16, and reducing the temperature rise. In this embodiment, the springboard support end 19 is bent 180 degrees to form an arc-shaped folding surface 23, and the arc-shaped folding surface is in line contact with the springboard portion 6.

[0032] Further, such as Figure 2-9 As shown, the pendulum piece portion 7 is composed of a pendulum piece supporting portion 10, an inclined connecting portion 11 and a contact mounting portion 12, the pendulum piece supporting portion 10 is formed by bending the side of the pendulum piece connecting portion 8 away from the springboard portion 6 by 85-95 degrees, the two ends of the inclined connecting portion 11 are respectively connected to the contact mounting portion 12 and the pendulum piece supporting portion 10, the inclined direction of the inclined connecting portion 11 is that the top of the pendulum piece supporting portion 10 is inclined toward the bottom of the contact mounting portion 12, the contact mounting portion 12 is arranged on one side of the upper part of the inclined connecting portion 11 close to the center of the pendulum piece connecting portion 8, the contact mounting portion 12 and the pendulum piece supporting portion 10 are arranged in a parallel structure, and a moving contact 13 in contact with the static contact end 9 is arranged on the contact mounting portion 12. Specifically, the swing piece part 7 composed of the swing piece support part 10, the inclined connecting part 11 and the contact mounting part 12 has such a structural arrangement that when the swing piece part 7 is driven by the springboard part 6 to swing, due to the arrangement of the inclined connecting part 11, the vertical center line of the contact mounting part 12 coincides with the vertical center line of the springboard part 6, and the distance between the contact mounting part 12 on the swing piece part 7 and the static contacts on the dual-control terminal 18 and the auxiliary terminal 17 is consistent, thereby ensuring that when the switch is pressed, the swing angles in the two actions of opening and closing are consistent, and the phenomenon of lack of contact or poor contact between the static contact on the side with the larger swing angle between the moving contact during the swinging of the switch can be avoided, thereby improving the contact stability between the contacts.

[0033] Further, such as Figure 2-9As shown, the angles between the inclined connection part 11 and the swing piece support part 10 and the contact mounting part 12 are all 135°±3°. Such a structural setting can make the contact between the springboard part 6 and the wiring unit 5 more stable during the swinging process of the integrated springboard 4, reduce the contact resistance, and improve the stability of the switch. At the same time, such a structural setting can also make the contact between the moving contact 13 and the static contact end 9 smoother during the swinging process of the swing piece part 7, reduce wear, and extend the service life of the switch. In addition, under this structure, the swing angle of the moving contact 13 during the swinging process is moderate, so that the static contact does not need to be placed far away from the moving contact, thereby reducing the required space and the volume of the switch box.

[0034] Further, such as Figure 2-9 As shown, swing limit ends 14 are provided on both sides of the springboard portion 6 away from the swing piece portion 7, and the swing limit ends 14 are bent toward the top of the springboard portion 6. There is a rounded structure 15 between the swing limit ends 14 and the springboard portion 6, and the angle of the rounded corner is 107°±2°. The swing limit ends 14 limit the swing position of the swing member 3 on the springboard portion 6. Specifically, in this embodiment, swing limit ends 14 are provided on both sides of the springboard portion 6, which are bent toward the top of the springboard portion 6, and the rounded structure 15 is formed between the springboard portion 6. This design accurately limits the swing position of the swing member 3 on the springboard portion 6, ensuring the stability and reliability of the switch. In the process of the swing member 3 swinging on the springboard, due to the setting of the rounded structure 15, it can be avoided that the swing member 3 is driven to directly contact the swing limit ends 14 when the switch is pressed, causing wear of the swing member 3, and the hand feeling of pressing the switch can be improved, ensuring the smoothness of the switch pressing.

[0035] Further, such as Figure 2-7 As shown, the wiring unit 5 includes a main terminal 16, an auxiliary terminal 17 and a dual-control terminal 18, the auxiliary terminal 17 and the dual-control terminal 18 are symmetrically arranged at both ends of the springboard portion 6, the main terminal 16 is arranged on one side of the auxiliary terminal 17, the static contact end 9 is respectively arranged on the dual-control terminal 18 and the auxiliary terminal 17, the main terminal 16 has a springboard support end 19, and the springboard portion 6 is swingably arranged on the springboard support end 19. Specifically, in this embodiment, during the swinging of the integrated springboard 4 on the springboard support end 19, the moving contact 13 and the static contact are in contact or disconnected, thereby realizing the on-off control of the circuit.

[0036] Specifically, by setting the above-mentioned integrated springboard 4, in one embodiment, the vertical distance between the center of the moving contact 13 and the swing limit end 14 can be in the range of 2.8mm~12.8mm, and the distance can be as small as 2.8mm. In the best embodiment, the vertical distance is 4.8mm, and such a structural setting can rotate integrated springboards of different sizes according to switch boxes of different thicknesses. By setting the above-mentioned integrated springboard 4, the vertical distance between the core pulling 28 and the springboard support end 19 is 5.15mm~18.15mm, and the distance can be as small as 5.5mm. Compared with the springboard switch and the swing plate switch in the prior art, such a structural setting has a smaller thickness of the switch box and the switch panel, so that the overall volume of the switch is relatively smaller, saving materials while facilitating installation and transportation.

[0037] Further, such as Figure 2-7 As shown, the main terminal 16, the auxiliary terminal 17 and the dual-control terminal 18 are all composed of corresponding terminal frames 20, terminal pieces 21 and terminal screws 22. The static contact end 9 is respectively arranged on the terminal pieces 22 corresponding to the dual-control terminal 18 and the auxiliary terminal 17, and the springboard support end 19 is arranged on the terminal piece 22 corresponding to the main terminal 16.

[0038] Specifically, Figure 2 As shown, in this embodiment, the switch panel 2 includes a panel bracket 24 and a panel button 25, the panel button 25 is rotatably connected to the panel bracket 24, a rotation groove 26 is provided on the side of the panel button 25 close to the panel bracket 24, a positioning shaft 27 is provided on the panel bracket 24 corresponding to the rotation groove 26, the positioning shaft 27 is embedded in the rotation groove 26, and the panel button 25 swings along the positioning shaft 27, and the distance from the center of the positioning shaft 27 to the top of the springboard support end 19 is 20.15mm±5mm. Such a structural setting can reduce the distance between the switch button 25 and the switch bracket, thereby reducing the swing angle of the switch button, and further reducing the thickness of the switch body.

[0039] Specifically, in the present embodiment, the swing angle of the switch button 25 is 1.5-2.8°, and such a swing angle can more effectively reduce the thickness of the switch.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
