[0002] In the bipolar double-break key switch, two conductive structures are configured, and the on-off of the two conductive structures is uniformly controlled through the key switch. Usually, in order to indicate the on-off state of the key switch, an indicating lamp assembly is also configured, which is electrically connected with the two conductive structures respectively.

[0051] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0052] In addition, reference numbers and / or reference letters can be repeated in different examples in the present application, and such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements being discussed. In addition, the present application provides examples of various specific processes and materials, but those skilled in the art can realize the application of other processes and / or the use of other materials.
[0053] The present application will be described below with reference to the drawings and specific embodiments:
[0054] The bipolar double-break key switch with an indicator light has two conductive structures corresponding to the neutral line and the live line, and can control the on-off of the two conductive structures and indicate the on-off state of the two conductive structures through the indicator light. Generally, the indicator light is arranged on the pressing part of the ratchet key mechanism of the key switch, and is electrically connected with the conductive reed of the key switch through the conductive spring to ensure the reliability of the electrical connection. However, the conductive spring also has a certain length, and there is a risk of radial deformation displacement, especially when the conductive spring abuts against the movable free end of the conductive reed, the displacement risk increases significantly, which seriously affects the functional stability and reliability of the indicator light.
[0055] Therefore, the present application provides a bipolar double-break key indicator switch, which aims to solve the technical problems of high displacement risk of the conductive spring of the indicator light of the bipolar double-break key indicator switch and unreliable electrical connection to some extent.
[0056] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the present application provides a bipolar double-break key indicator switch, which is adapted to and maintains the stability of the form, position and movement form of the conductive spring of the indicator light through structural design.
[0057] Specifically, the dual-pole dual-break push button indicator switch may include a housing 1, a first stationary contact 21, a first moving contact 22, a second stationary contact 31, a second moving contact 32, a pusher 4, a ratchet button mechanism 5, and an indicator light assembly 6.
[0058] The housing 1 serves as the support frame for the entire double-pole double-break push-button indicator switch, supporting and fixing the first stationary contact 21, the first moving contact 22, the second stationary contact 31, the second moving contact 32, the pusher 4, the ratchet button mechanism 5, and the indicator light assembly 6. The housing 1 also contains corresponding cavities adapted to each of the aforementioned components, providing a fixing structure. Generally, the housing 1 can be a single-piece molded part or composed of multiple components assembled together.
[0059] The first stationary contact 21 and the first moving contact 22 are detachably connected and disposed within the housing 1, forming the first conductive structure 2 of the double-pole double-break push button indicator switch; wherein, the first moving contact 22 has a first free end 221, which can move under the action of external force to approach or move away from the first stationary contact 21, thereby establishing or breaking the connection with the first stationary contact 21.
[0060] The second stationary contact 31 and the second moving contact 32 are detachably connected and disposed within the housing 1, forming the second conductive structure 3 of the double-pole double-break push button indicator switch; wherein, the second moving contact 32 has a second free end 321, which can move under the action of external force to approach or move away from the second stationary contact 31, thereby establishing or breaking the connection with the second stationary contact 31.
[0061] The pusher 4 is used to contact and drive the first free end 221 and the second free end 321; wherein, the pusher 4 can move along a set trajectory under the action of external force to push the first free end 221 and the second free end 321 close to the first stationary contact piece 21 and the second stationary contact piece 31.
[0062] The ratchet button mechanism 5 is disposed on the housing 1 as a switch button and is connected to the push member 4. Thus, by pressing, the push member 4 is driven to move, and then the position of the push member 4 is locked by the position holding function of the ratchet button mechanism 5, thereby maintaining the on or off state of the double-pole double-off button indicator switch.
[0063] The indicator light assembly 6 is equipped with two power terminals, which can be electrically connected to the first moving contact 22 and the second moving contact 32 through the first conductive spring 61 and the second conductive spring 62, respectively. When the first conductive structure 2 and the second conductive structure 3 are conducting, the indicator light assembly 6 can obtain electrical energy and then light up to indicate the on state of the double-pole double-break button indicator switch. If either the first conductive structure 2 or the second conductive structure 3 is in the off state, the indicator light assembly 6 cannot form a conducting loop and therefore cannot light up.
[0064] It is worth noting that in some embodiments, the indicator light assembly 6 is disposed on the outside of the housing 1 and moves synchronously with the pressing end of the ratchet button mechanism 5. Correspondingly, the first conductive spring 61 and the second conductive spring 62 will undergo compression deformation and reset. In order to maintain the deformation direction of the first conductive spring 61 and the second conductive spring 62 in the axial direction and limit the radial displacement, a limiting hole 41 is provided on the push member 4 to accommodate and limit the first conductive spring 61 and the second conductive spring 62. The inner diameter of the limiting hole 41 is slightly larger than the outer diameter of the first conductive spring 61 and the second conductive spring 62, thereby maintaining the smoothness of the expansion and contraction deformation of the first conductive spring 61 and the second conductive spring 62, while also taking into account the ability to maintain the position and orientation of the first conductive spring 61 and the second conductive spring 62.
[0065] The bipolar double-break push-button indicator switch provided in this application includes a housing, a first stationary contact, a first moving contact, a second stationary contact, a second moving contact, a pusher, a ratchet button mechanism, and an indicator light assembly. The two power terminals of the indicator light assembly are connected to the first free end of the first moving contact and the second free end of the second moving contact via conductive springs. The ratchet button mechanism abuts against the first and second free ends via the pusher, thereby uniformly realizing the movement of the first and second free ends and controlling the switch's on / off state. A limiting hole is provided on the pusher, and the bodies of the two conductive springs pass through the limiting hole, thereby increasing resistance to external interference, maintaining the stability of the position and shape of the contact portion between the conductive springs and the first and second free ends, and ensuring the stability of the elastic electrical connection.
[0066] In some embodiments, the first free end 221 and the first stationary contact piece 21 are spaced apart along the pressing direction of the ratchet button mechanism 5, so that when an external force presses the pressing end of the ratchet button mechanism 5, the output end of the ratchet button mechanism 5 can push the pusher 4 to move, thereby pushing the first free end 221 towards the first stationary contact piece 21, and then making contact and connecting. Alternatively, after pressing the pressing end of the ratchet button mechanism 5, the ratchet button mechanism 5 resets, the output end of the ratchet button mechanism 5 and the pusher 4 reset and retract, thereby releasing the push on the first free end 221, the first free end 221 naturally and elastically resets, disconnecting from the first stationary contact piece 21, and then breaking the circuit.
[0067] Similarly, the second free end 321 and the second stationary contact 31 are spaced apart along the pressing direction of the ratchet button mechanism 5, so that when the pressing end of the ratchet button mechanism 5 is pressed, the output end of the ratchet button mechanism 5 can push the pusher 4 to move, thereby pushing the second free end 321 towards the second stationary contact 31, and then conducting. Alternatively, when the pressing end of the ratchet button mechanism 5 is pressed, the output end of the ratchet button mechanism 5 and the pusher 4 reset and retract, thereby releasing the push on the second free end 321, and the second free end 321 naturally and elastically resets, disconnecting from the second stationary contact 31, and then breaking the circuit.
[0068] In some embodiments, the ratchet button mechanism 5 can be a typical ratchet button function mechanism consisting of a large ratchet 51, a small ratchet 52, and a return spring 53, which can switch between two locking positions by pressing. Specifically, the large ratchet 51 and the small ratchet 52 are nested and driven by ratchet teeth. The return spring 53 is disposed inside the small ratchet 52 and abuts against the pusher 4, thereby pushing the small ratchet 52 and the return spring 53 by pressing the large ratchet 51, thus realizing the output of pushing torque. At the same time, the housing 1 has a constraint hole 11 and a guide rib on the hole wall. The large ratchet 51 cooperates with the guide rib to keep the large ratchet 51 moving back and forth in a set direction. The teeth of the large ratchet 51 and the small ratchet 52 have a certain curvature, which can guide the large ratchet 51 and the small ratchet 52 to rotate relative to each other when they are engaged, while the large ratchet 51 remains stationary in the circumferential direction. Thus, when the large ratchet 51 is pressed, the small ratchet 52 rotates under the action of the return spring 53 and the curved teeth, and then maintains the position after rotation.
[0069] In some embodiments, since the indicator light assembly 6 is located outside the housing 1, and the housing 1 is also provided with a clearance hole 12, the first conductive spring 61 and the second conductive spring 62 can be embedded in the clearance hole 12 to be compatible with the conductive functional structure and the external setting method of the indicator light assembly 6.
[0070] In some embodiments, the indicator light assembly 6 includes a light-emitting element 63 and a pressing bracket 64; the pressing bracket 64 abuts against the pressing end of the ratchet button mechanism 5, the light-emitting element 63 is installed in the pressing bracket 64, and pressing the pressing bracket 64 can drive the pressing bracket 64, the light-emitting element 63 and the pressing end of the ratchet button mechanism 5 to move synchronously.
[0071] Generally, the light-emitting element 63 is equipped with two power supply terminals, which are electrically connected to the ends of the first conductive spring 61 and the second conductive spring 62, respectively.
[0072] In some embodiments, the light-emitting element 63 may be a printed circuit board with integrated LEDs, which is secured within the pressing bracket 64. The printed circuit board is provided with two power terminals, which respectively abut against the ends of the first conductive spring 61 and the second conductive spring 62.
[0073] In some embodiments, a light-transmitting cap 65 may also be installed on the pressing bracket 64 to cover the LED light, thereby constraining and protecting the LED light.
[0074] Generally, the size, specifications, shape, and other features of the light-emitting area can be set on the light-emitting cap 65 to make the light-emitting shape distinctive.
[0075] In some embodiments, in order to maintain the stability of the posture and trajectory of the pressing bracket 64, a guide post 13 can be provided on the housing 1, and a guide hole 641 is correspondingly opened on the pressing bracket 64. The guide post 13 is embedded in the guide hole 641, and the guiding direction of the guide post 13 is set along the pressing direction of the ratchet button mechanism 5.
[0076] Generally, the number of guide posts 13 and guide holes 641 can be set to multiple, such as two or more.
[0077] In some embodiments, considering that the pusher 4 abuts against the ratchet button mechanism 5 and the first movable contact 22 and the second movable contact 32, and moves with the first movable contact 22 and the second movable contact 32, it is necessary to ensure the stability of the movement of the pusher 4. Therefore, a guide mechanism 7 can be provided between the housing 1 and the pusher 4 to ensure the stability of the movement trajectory of the pusher 4 relative to the housing 1.
[0078] Generally, the guiding direction of the guiding mechanism 7 can be set to the pressing direction of the ratchet button mechanism 5, so that the moving direction of the pusher 4 can be stably maintained in the pressing direction of the ratchet button mechanism 5, thereby limiting displacement in other directions and ensuring the accuracy control of the displacement of the first moving contact 22 and the second moving contact 32.
[0079] In some embodiments, the guiding mechanism 7 may include a guide rib plate 71 and a guide groove 72. The guide rib plate 71 may be disposed inside the housing 1, and the guide groove 72 may be directly formed on the pusher 4. The pusher 4 is sleeved on the guide rib plate 71 through the guide groove 72, so that the pusher 4 can move stably relative to the housing 1 by relying on the relative movement of the guide rib plate 71 and the guide groove 72, thereby stably pushing the first movable contact piece 22 and the second movable contact piece 32 to move.
[0080] Generally, the guide rib plate 71 can be positioned in the middle between the first movable contact piece 22 and the second movable contact piece 32, so as to keep the force applied by the pusher 4 to the first movable contact piece 22 and the second movable contact piece 32 located on both sides of the guide groove 72, so as to ensure the uniformity and reliability of the force.
[0081] In some embodiments, in order to realize the guide groove 72 on the pusher 4, a matching groove can be directly formed on the side of the pusher 4 near the guide rib 71.
[0082] The guide groove 72 has a certain depth in the pressing direction of the ratchet button mechanism 5, which can ensure that the guide groove 72 is always sleeved on the guide rib plate 71 during the movement of the pusher 4 relative to the housing 1, thus ensuring the reliability of the guide and limit function.
[0083] In some embodiments, in order to reduce the thickness of the pusher 4, a pair of clamping plates 721 may be provided on the pusher 4 to form the guide groove 72 together with one side surface of the pusher 4.
[0084] The spacing between the pair of clamping plates 721 is slightly greater than the thickness of the guide rib plate 71.
[0085] In some embodiments, a groove of a certain depth may be formed on one side surface where the pair of clamping plates 721 are located, which cooperates with the stack of clamping plates 721 to form the complete guide groove 72, thereby reducing the overall height of the pusher to a certain extent.
[0086] In some embodiments, considering that direct contact between the plate surfaces can easily create a certain surface-to-surface contact adsorption resistance, affecting the smoothness of the pusher 4's movement, local structures such as holes, grooves, and protrusions can be opened on the guide rib plate 71 and / or the clamping plate 721 to avoid the entire contact surface being in a surface-to-surface contact state, which can reduce static adsorption resistance to a certain extent.
[0087] In some embodiments, in order to reduce the overall thickness of the housing 1, a through hole 14 can be made in the housing 1 to avoid the clamping plate 721, thereby allowing the clamping plate 721 to be made longer to ensure the functional reliability of the guide mechanism 7.
[0088] In some embodiments, considering that the reset spring 53 of the ratchet button mechanism 5 abuts against the pusher 4, in order to ensure the stability of the abutting state, a limiting groove 42 can be provided on the pusher 4, and the reset spring 53 of the ratchet button mechanism 5 is embedded in the limiting groove 42 to limit the lateral displacement of the reset spring 53.
[0089] Generally, the inner diameter of the limiting groove 42 is slightly larger than the outer diameter of the reset spring 53, thus achieving a good match.
[0090] In some embodiments, a limiting boss 421 may be provided on the bottom surface of the limiting groove 42, and the limiting boss 421 may be embedded in the end of the return spring 53 to further enhance the position retention reliability of the return spring 53.
[0091] In some embodiments, considering that the edge of the limiting hole 41 affects the extension and contraction of the reset spring 53, the edge of the limiting hole 41 can be set as an arc surface or be chamfered.
[0092] In some embodiments, for the purpose of facilitating electrical connection, a first wire bonding portion 211 may be provided on the first stationary contact piece 21 for external wire bonding.
[0093] Accordingly, in order to facilitate electrical connection, a second welding part 311 can be provided on the second stationary contact piece 31 for welding external wires.
[0094] See Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 In some embodiments, to facilitate electrical connection, a first crimping portion 212 may be configured on the first stationary contact piece 21 for crimping external wires.
[0095] Accordingly, in order to facilitate electrical connection, a second crimping part 312 can be provided on the second stationary contact piece 31 for crimping external wires.
[0096] In some embodiments, the double-pole double-break push-button indicator switch may also be equipped with a terminal block 8 to achieve wire clamping electrical connection. Specifically, the double-pole double-break push-button indicator switch further includes a terminal block 8, in which the first wire clamping part 212 and the second wire clamping part 312 are embedded to achieve wire clamping connection.
