Description

Technical Field

[0001] This utility model relates to the field of electrical switch technology, and in particular to a switch spring and toggle switch with dual channels. Background Technology

[0002] The switch spring is used for electrical conduction in the switch. It conducts electricity through contact between a moving contact fixed at one end of the spring and a stationary contact inside the switch. For example... Figure 1 As shown, all existing switch springs are single-channel. Under high current conditions, single-channel switch springs are prone to overheating, which may lead to softening of the switch springs and poor switching performance. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a switch spring and toggle switch with dual channels.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: a switch spring with dual channels, comprising a spring body, a moving contact end and a fixed end respectively formed at both ends of the spring body, a spring channel formed between the moving contact end and the fixed end, two spring channels formed, the two spring channels are arranged in parallel, a gap is formed between the two spring channels, and the beginning and end of the two spring channels converge on the moving contact end and the fixed end respectively.

[0005] Preferably, the two spring channels are formed symmetrically from left to right.

[0006] Preferably, the moving contact end is formed in a conical shape, and the fixed end is formed in a rectangular shape.

[0007] Preferably, a plurality of symmetrical limiting portions are formed on the fixed end, the limiting portions including inserts formed on the outer side of the fixed end and slots formed on the fixed end.

[0008] A toggle switch includes a switch base, a top cover covering the switch base, a strip groove formed on the top cover, a lever slidably connected in the strip groove, a spring strip and a ball ball disposed below the lever, a wave-shaped stop strip formed on the switch base corresponding to the strip groove, and a stationary contact terminal disposed in the switch base. It also includes a dual-channel switch spring, wherein the wave-shaped stop strip is inserted in the gap between two spring channels, and the lever simultaneously contacts both spring channels when sliding on the strip groove and the wave-shaped stop strip.

[0009] Preferably, the switch base has a socket corresponding to the insert of the limiting part of the switch spring, and the switch base also has a post corresponding to the slot on the fixed end of the switch spring.

[0010] Compared with existing technologies, this solution increases the overcurrent area of ​​the spring body by adding a spring channel between the moving contact end and the fixed end, reduces the heat generation of a single spring channel, and increases the overall current that can be passed, allowing the applied switch products to pass a current of 20A, which is greater than the general 15A current.

[0020] The present invention will be further described below with reference to specific embodiments: Example

[0021] This utility model discloses a dual-channel switch spring, comprising a spring body 1, a moving contact end 11 and a fixed end 12 respectively formed at both ends of the spring body 1, and a spring channel 13 formed between the moving contact end 11 and the fixed end 12. The spring channel 13 is suspended from the fixed end 12 to the moving contact end 11, and an upward protrusion is formed on the spring channel 13 to facilitate downward pressing of the spring channel 13, allowing the moving contact end 11 to swing up and down. Figure 1As shown, the existing single spring channel 13 has a small overcurrent area, which can easily cause overheating and switch failure. Simply increasing the area of ​​the spring channel 11 will increase the overall size of the switch, which does not meet the requirements of electrical miniaturization, or the overall layout will be unevenly stressed, which will greatly affect the service life of the switch.

[0022] like Figure 2-3 As shown, in this application, the spring channel 13 is formed in two parallel arrangements, with a gap 14 formed between the two spring channels 13, and the beginning and end of the two spring channels 13 converge on the moving contact end 11 and the fixed end 12 respectively.

[0023] The second spring contact channel 13, which is set in parallel, not only increases the overcurrent area and allows for a larger current of 20A than the 15A current in the market, but also the two spring contact channels 13 are set separately, and the gap 14 between them can better integrate with the switch, reduce the size of the switch, and the force on both sides is relatively uniform, which can extend the service life of the switch.

[0024] To achieve a better stress distribution, the two spring channels 13 are symmetrically formed on the left and right sides.

[0025] The moving contact end 11 is formed into a cone shape, and the fixed end 12 is formed into a rectangle, which can increase the area of ​​the fixed position and reduce the weight of the moving contact end 11 while maintaining a large overcurrent area.

[0026] To facilitate assembly, a plurality of symmetrical limiting portions 15 are formed on the fixed end 12. The limiting portions 15 include inserts 151 formed on the outside of the fixed end 12 and slots 152 formed on the fixed end 12.

[0027] like Figure 4-9 As shown, a toggle switch includes a switch base 2, an upper cover 3 covering the switch base 2, a strip groove 31 formed on the upper cover 3, a lever 4 slidably connected in the strip groove 31, a spring strip 5 and a ball bearing 6 disposed below the lever 4, a wave-shaped stop strip 21 formed on the switch base 2 corresponding to the strip groove 31, and a stationary contact terminal 7 disposed in the switch base 1. It also includes a switch spring 1 with dual channels as described above. The wave-shaped stop strip 21 is inserted in the gap 14 between the two spring channels 1. When the lever 4 slides on the strip groove 31 and the wave-shaped stop strip 21, it simultaneously contacts and acts on the two spring channels 13.

[0028] Compared to the single spring channel 13 in the prior art, the switch spring 1 not only increases the overcurrent area and allows for a larger current flow, but also the two spring channels 13 are set separately, and the gap 14 between them can better integrate with the switch, reducing the size of the switch while ensuring that the force on both sides is relatively uniform, thus extending the service life of the switch.

[0029] The switch base 2 is formed with a socket 22 corresponding to the insert 151 of the limiting part 15 of the switch spring 1. The switch base 2 is also formed with a post 23 corresponding to the slot 152 on the fixing end 12 of the switch spring 1. This ensures that the switch spring 1 will not move during soldering and assembly under the action of the limiting part 15, and is stably fixed on the switch base 2, thus ensuring the stability of the product.
