Description

Technical Field

[0001] The utility model relates to the technical field of toggle switches, and particularly relates to a synchronous conductive switch. Background Art

[0002] A toggle switch is used to connect or disconnect a circuit by toggling a switch handle, so as to achieve the purpose of switching the circuit. It is generally used in low-voltage circuits and has the characteristics of flexible slider movement and stable and reliable performance. Most toggle switches have a housing, with contact pieces respectively arranged at both ends of the housing, and pins extending outward from the contacts to the outside of the housing. Two contact bridges are swingably arranged in the housing, and different pins are energized by the swing of the contact bridges, so as to realize gear changes. However, in the manufacturing process, the precision requirements for the two contact bridges are relatively high. If the deformation degrees of the two contact bridges are inconsistent, the front and rear pins cannot be energized simultaneously, resulting in the failure of the toggle switch and a high defective rate of products in the manufacturing process. Summary of the Utility Model

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect that when the deformation degrees of the two contact bridges in the prior art are inconsistent, the front and rear pins cannot be energized simultaneously, so as to provide a synchronous conductive switch with a high product qualification rate.

[0004] To this end, the utility model provides a synchronous conductive switch, which includes a base and a cover plate arranged above the base. A button is arranged between the base and the cover plate. Two contact bridges are arranged below the button. The contact bridges are squeezed and arranged between the base and the button. The contact bridges are clamped below the button. A conductive sheet is arranged below the contact bridges. The conductive sheet includes a first output end, a second output end, and a conductive part arranged between the first output end and the second output end for connecting the two.

[0005] Further: The conductive sheet includes a common terminal and a plurality of output terminals located on the side of the common terminal. The first output end and the second output end are located on both sides of the common terminal and the output terminals. The first output end and the second output end are both connected with pins. One end of the contact bridge is connected with the common terminal, and the other end is connected with any output terminal. The contact bridge includes a connection end clamped below the button and elastic ends arranged on both sides of the connection end. The elastic ends are bent downward towards the end close to the conductive sheet, and contacts are arranged on the elastic ends.

[0006] Further: One end of the contact bridge is connected with the common terminal, and the other end is connected with any output terminal. The contact bridge includes a connection end clamped below the button and elastic ends arranged on both sides of the connection end. The elastic ends are bent downward towards the end close to the conductive sheet, and an extension end inclined upward is further arranged on the side of the elastic end far away from the connection end.

[0007] Furthermore: a plurality of positioning blocks for positioning the contact bridge are arranged on the lower end surface of the button, and a card cavity for the contact bridge to be inserted is formed between the positioning blocks and the button.

[0008] Further: the connecting end is provided with a clamping end on both sides, the lower end surface of the button is provided with a limiting cavity, the clamping end at one end of the connecting end is clamped in the clamping cavity, and the clamping end at the other end is provided in the limiting cavity.

[0024] Embodiment

[0025] This embodiment provides a synchronous conductive switch, which includes a base 1 and a cover plate 2 arranged above the base 1. A button 11 is arranged between the base 1 and the cover plate 2. Two contact bridges 3 are arranged below the button 11. The contact bridges 3 are squeezed and arranged between the base 1 and the button 11. The contact bridges 3 are clamped below the button 11. A conductive sheet 4 is arranged below the contact bridges 3. The conductive sheet 4 includes a first output end 41, a second output end 42, and a conductive part 43 arranged between the first output end 41 and the second output end 42 for connecting the two ends.

[0026] The above specific improvement is as follows: As Figure 1 shown, compared with the prior art, even if the two contact bridges 3 are deformed, when the button 11 is pressed downward, as long as one side of the first output end 41 and the second output end 42 is energized, the current will be conducted to the other end through the conductive part 43, so as to realize the on-off of the entire conductive switch.

[0027] Based on the above embodiment: The conductive sheet 4 includes a common terminal 5 and a plurality of output terminals 6 located on the side of the common terminal 5. The first output end 41 and the second output end 42 are located on both sides of the common terminal 5 and the output terminals 6. The first output end 41 and the second output end 42 are both connected with pins 44. One end of the contact bridge 3 is connected with the common terminal 5, and the other end is connected with any output terminal 6. The contact bridge 3 includes a connection end 31 clamped below the button 11 and elastic ends 32 arranged on both sides of the connection end 31. The elastic ends 32 are bent downward toward the end close to the conductive sheet 4, and contact points 33 are arranged on the elastic ends 32.

[0028] Based on the above embodiment: One end of the contact bridge 3 is connected with the common terminal 5, and the other end is connected with any output terminal 6. The contact bridge 3 includes a connection end 31 clamped below the button 11 and elastic ends 32 arranged on both sides of the connection end 31. The elastic ends 32 are bent downward toward the end close to the conductive sheet 4, and an extending end 34 inclined upward is further arranged on the side of the elastic ends 32 away from the connection end 31.

[0029] The above specific improvement is as follows:

[0030] Embodiment 1: As Figure 2 and Figure 3As shown, the conductive sheet 4 includes a common terminal 5 and output terminals 6 located on both sides of the common terminal 5. Both the common terminal 5 and the output terminal 6 are provided with a first output terminal 41 and a second output terminal 42. The current enters from the first output terminal 41 and is output from the second output terminal 42. By moving the contact bridge 3, the contact bridge 3 includes a connecting end 31 and elastic ends 32 arranged on both sides of the connecting end 31. The elastic end 32 has a contact 33. The contacts 33 at both ends of the contact bridge 3 contact the common terminal 5 and different output terminals 6 respectively, thereby realizing gear switching.

[0031] Example 2: Figure 2 and Figure 4 As shown, the contact bridge 3 includes a connecting end 31 and elastic ends 32 arranged on both sides of the connecting end 31, and an extension end 34 is arranged on the side of the elastic end 32. The elastic end 32 on one side is connected to the common terminal 5. When the elastic end 32 on the other end needs to be cut from one output terminal 6 to another output terminal 6, the button 11 moves to the left or right, and the button 11 is pressed downward, thereby squeezing the accommodating space of the contact bridge 3. After the connecting end 31 is pressed downward, the elastic ends 32 on both sides are deformed toward the button 11 (that is, upwardly deformed). After the assembly is completed, the contact bridge 3 is squeezed and arranged between the base 1 and the base 1. Between the buttons 11, due to the elasticity of the deformation end itself, the contact state with the conductive sheet 4 is always maintained. Even if the contact bridge 3 is more or less deformed, it can ensure that the elastic ends 32 on both sides are always in contact with the conductive sheet 4, thereby reducing the manufacturing accuracy of the contact bridge 3 and improving the product qualification rate. During the gear switching process, when the elastic end 32 is deformed to a certain space, the top position of the extension end 34 will conflict with the lower end surface of the button 11, thereby preventing the contact bridge 3 from further deformation, reducing the deformation degree of the elastic end 32, and avoiding the elastic failure of the elastic end 32, thereby improving the service life of the contact bridge 3.

[0032] On the basis of the above embodiment: the lower end surface of the button 11 is provided with a plurality of positioning blocks 7 for positioning the contact bridge 3 , and a card cavity 71 for the contact bridge 3 to be inserted is formed between the positioning blocks 7 and the button 11 .

[0033] On the basis of the above embodiment: the connecting end 31 is provided with a snap-on end 311 on both sides, the lower end surface of the button 11 is provided with a limiting cavity 8, the snap-on end 311 at one end of the connecting end 31 is snap-on in the clamping cavity 71, and the snap-on end 311 at the other end is provided in the limiting cavity 8.

[0034] The above-mentioned specific improvements are as follows: four positioning blocks 7 are arranged on the lower end surface of the button 11, and the two positioning blocks 7 and the protruding parts of the lower end surface of the button 11 surround a card cavity 71 for the contact bridge 3 to be inserted into. In order to increase the contact area between the contact bridge 3 and the button 11, card connection ends 311 are arranged on both sides of the connecting end 31, a limiting cavity 8 is opened on the button 11, and a card cavity 71 is arranged between the two positioning blocks 7. The two card connection ends 311 of the connecting end 31 are respectively inserted into the limiting cavity 8 and the card cavity 71, and the three are interference fit, thereby effectively fixing the position of the contact bridge 3.

[0035] On the basis of the above embodiment: a protrusion 12 is provided on the upper end surface of the button 11, and a slot 13 for a card block 21 to be inserted is arranged between adjacent protrusions 12, the card block 21 is arranged on the cover plate 2, and a toggle block 14 is also provided above the button 11 to move the button 11 due to the driving force.

[0036] The above-mentioned specific improvements are as follows: when switching gears, the toggle block 14 needs to be moved. When moving, the card block 21 needs to overcome the limit of the protrusion 12 and enter the adjacent protrusion 12. When switching gears, the card block 21 has a downward squeezing force on the button 11 and the protrusion 12, so that the button 11 squeezes the contact bridge 3, causing the contact bridge 3 to deform, resulting in its elastic end 32 being separated from the conductive sheet 4. When the card block 21 enters the adjacent card slot 13, it means that the gear switching is completed, and the card block 21 loses the external force, so that the contact bridge 3 continues to maintain the contact state with the conductive sheet 4 due to its own elastic restoring force, thereby realizing the power-on of the first output terminal 41 and the second output terminal 42.

[0037] On the basis of the above embodiment: the base 1 is provided with an auxiliary cross bar 9 for assisting the button 11 to move, and an avoidance cavity 91 adapted to the cross bar is formed between the positioning blocks 7 .

[0038] The above-mentioned specific improvements are as follows: in order to ensure that the auxiliary button 11 can move smoothly, an auxiliary cross bar 9 is set on the base 1, and the positioning block 7 on the lower end surface of the button 11 forms an avoidance cavity 91 for avoiding the cross bar. After the installation is completed, the positioning block 7 will be located on both sides of the cross bar, so that the limit button 11 can only move laterally, ensuring that the gear switching can be carried out smoothly, and in order to ensure the waterproof and dustproof function of the card block, at the cover plate 2, a layer of coating sheet 92 is covered on the top of the card block 21.

[0039] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
