Description
Technical Field
[0001] This invention relates to electrical technology, and more particularly to spring assemblies and switches. Background Technology
[0002] A switch is a common device for switching current on and off. A typical switch is a rocker switch, which includes: a rocker with a moving contact, a transition piece connected to a pin assembly, and a panel that abuts against the transition piece. The user presses the panel to drive the transition piece to rotate, which in turn causes the pin assembly to move the rocker, making the moving contact contact or separate from the stationary contact, thereby achieving the purpose of turning the switch on or off.
[0003] However, due to the structure and layout of the components in a rocker switch, its thickness is usually designed to be large enough, making it difficult to make an ultra-thin switch. Summary of the Invention
[0004] In view of this, the present invention provides a spring assembly and a switch that can solve the technical problems existing in the related art.
[0005] Specifically, the following technical solutions are included:
[0006] On the one hand, a spring contact assembly is provided, the spring contact assembly including: a spring contact, a terminal block and a moving contact;
[0007] The terminal block is connected to and fixed to the middle of the spring piece;
[0008] The moving contact is connected to and fixed to the end of the spring piece;
[0009] The spring is configured such that it can be deformed by an external force, causing the moving contact to move between a first position and a second position.
[0010] In some possible implementations, the spring includes: a terminal connection segment, one or two elastic segments, and one or two contact connection segments;
[0011] The first end of the elastic segment is connected to one end of the terminal connection segment, and the second end of the elastic segment is connected to the corresponding contact connection segment;
[0012] The terminal connection section is used to connect to the wiring terminal;
[0013] The elastic segment can be pressed and deformed, causing the moving contact to move between a first position and a second position;
[0014] The contact connection segment is used to connect with the moving contact.
[0015] In some possible implementations, there is an angle between the elastic segment and the terminal connection segment, the angle being in the range of 120° to 180°.
[0016] In some possible implementations, both the contact connection segment and the elastic segment are arranged horizontally and are located in the same horizontal plane.
[0017] In some possible implementations, the contact connection segment includes: a guide segment and a connecting segment connected together, the guide segment being arranged at an angle relative to the elastic segment such that the connecting segment is located above or below the elastic segment.
[0018] In some possible implementations, the elastic segment includes: a first elastic segment and a second elastic segment connected together, wherein the end of the first elastic segment away from the second elastic segment is connected to the terminal connection segment, and the end of the second elastic segment away from the first elastic segment is connected to the contact connection segment;
[0019] From the terminal connection segment to the second elastic segment, the width of the first elastic segment gradually decreases, and the minimum width of the first elastic segment is equal to the width of the second elastic segment.
[0020] In some possible implementations, the spring is prepared by a one-piece molding process.
[0021] On the other hand, a switch is also provided, the switch comprising any of the aforementioned spring-loaded components.
[0022] In some possible implementations, the switch further includes: a base, a panel, a transition member, a swing positioning member, and a stationary contact assembly;
[0023] Both the spring assembly and the stationary contact assembly are located inside the base, and the moving contact on the spring assembly corresponds to the stationary contact on the stationary contact assembly.
[0024] The transition component includes: a transition component body and a driving part located on the side of the transition component body; the transition component body is connected to the panel and is also hinged to the base, and the panel can be pressed and rotated relative to the base;
[0025] The driving part corresponds to the elastic segment of the spring assembly. The driving part can act on the corresponding position of the elastic segment to deform it, thereby causing the moving contact to contact or separate from the corresponding stationary contact.
[0026] The swing positioning element is connected between the transition body and the base, and the swing positioning element is configured to stabilize the transition and the panel as a whole in the closed position and the open position.
[0027] In some possible implementations, the driving part acts on the elastic segment in the following ways: the driving part presses down on the elastic segment, and optionally, the driving part pulls up on the elastic segment.
[0028] In some possible implementations, the swing positioning element is a momentary spring, with a first end connected to the side of the base and a second end connected to the side of the transition element.
[0029] In some possible implementations, the transition element is a one-piece structural component.
[0030] In some possible implementations, the transition component is a split structural component, which includes multiple sub-transition components connected by a rotatable connection.
[0031] In some possible implementations, the base includes a seat and a cover, the seat having a receiving cavity to accommodate the spring assembly and the stationary contact assembly;
[0032] The cover is detachably connected to the seat and covers the upper port of the accommodating cavity. The opposite first and second sides of the cover are hinged to the two sides of the transition member, and the opposite third and fourth sides of the cover are each connected to one of the swing positioning members.
[0033] The driving part of the transition piece penetrates the cover and extends into the accommodating cavity to interact with the spring sheet.

[0035] The first and second opposite sides of the accommodating cavity are hinged to the two sides of the transition member, and the third and fourth opposite sides of the accommodating cavity are each connected to one of the swing positioning members.
[0036] In some possible implementations, the switch is a normally closed switch, the moving contact is located below the corresponding stationary contact, and the contact pressure between the moving contact and the stationary contact is provided by the spring.
[0037] In some possible implementations, the switch is a normally open switch, the moving contact is located above the corresponding stationary contact, and the contact pressure between the moving contact and the stationary contact is provided by the transition element.
[0038] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:
[0039] The spring assembly provided in this embodiment of the invention elastically deforms the portion of the spring located between the terminal and the moving contact by pressing it. This causes the moving contact at the end of the spring to move as the spring deforms, thereby switching the moving contact between a first position and a second position. When the spring assembly is used in a switch, the position of the moving contact can be changed by designing a transition member in the switch to deform the elastic segment (e.g., by pressing the transition member downwards against the elastic segment). Compared to rocker switches where the transition member must drive the rocker to change the position of the moving contact, this operation of the spring assembly provided in this embodiment of the invention allows for smaller longitudinal dimensions (i.e., thickness) of both the transition member and the spring, which significantly reduces the thickness of the switch, enabling the fabrication of ultra-thin switches. Furthermore, since the terminal connection section is fixedly connected to the spring, the terminal and the moving contact remain electrically connected during the change of the moving contact position, eliminating the arcing problem caused by rocker rocker movement.

Detailed Implementation
[0066] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0067] The directional terms used in the embodiments of this invention, such as "upper," "lower," and "side," are generally... Figure 4 The relative positions shown are for reference only, and these directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged. (It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in this embodiment of the invention are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the attached figures). If the specific orientation changes, the directional indication will also change accordingly.)
[0068] For the switch involved in the embodiments of the present invention, the position of the panel is defined as up, the position of the base is defined as down, and the thickness of each component involved in the embodiments of the present invention is considered to be the dimension along the vertical direction (i.e., longitudinal direction).
[0069] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0070] A switch is a common device for switching current on and off. A typical switch is a rocker switch, which includes: a rocker with a moving contact, a transition piece connected to a pin assembly, and a panel that abuts against the transition piece. The user presses the panel to drive the transition piece to rotate, which in turn causes the pin assembly to move the rocker, making the moving contact contact or separate from the stationary contact, thereby achieving the purpose of turning the switch on or off.
[0071] For example, rocker switches are commonly used as wall switches. Currently, the trend in wall switch development is towards large panels and small swing angles. However, due to the structure and layout of the components in a rocker switch, its thickness is usually designed to be sufficiently large, making it difficult to manufacture ultra-thin switches. The reasons for these defects in rocker switches include at least the following:
[0072] (1) In a rocker switch, the transition piece has a downwardly extending swing arm, which connects to the tumbler assembly. The swing arm, tumbler assembly, and rocker are distributed sequentially along the longitudinal direction, which makes the thickness of the rocker switch (which is perpendicular to the wall direction) generally larger. Correspondingly, the installation depth of the rocker switch in the junction box on the wall is also larger, which makes the volume of the junction box need to be designed to be larger.
[0073] (2) In order to ensure that the contact pressure between the moving contact and the stationary contact meets the requirements, if the swing angle of the panel is reduced, the swing arm length of the transition piece must be increased accordingly, which will further increase the thickness of the rocker switch.
[0074] (3) When the pin assembly moves the rocker, the end of the pin assembly slides horizontally along the rocker, which generates sliding friction. Furthermore, the end of the pin assembly is also prone to wear.
[0075] (4) The rocker is connected to the terminal block through the support member. The support member supports the rocker and allows it to swing. When the rocker swings, it is easy to bounce, which will cause the rocker to separate from the support member for a short time, which will cause arcing problems.
[0076] To address the technical problems existing in related technologies, embodiments of the present invention provide a spring assembly that can be used in switches. Based on its novel structural design, this spring assembly can significantly reduce the thickness of the switch when applied to a switch, which is beneficial for obtaining an ultra-thin switch.
[0077] Appendix Figure 1 An example of the structure of a spring assembly 1 is shown in the attached figure. Figure 1 As shown, the spring assembly 1 includes: a spring 11, a terminal block 12, and a moving contact 13. The terminal block 12 is connected to and fixed to the middle of the spring 11; the moving contact 13 is connected to and fixed to the end of the spring 11; the spring 11 is configured such that it can be deformed by an external force, causing the moving contact 13 to move between a first position and a second position.
[0078] The spring assembly 1 provided in this embodiment of the invention can be used as a switch. The terminal 12 is fixed to the middle of the spring 11, and the moving contact 13 is fixed to the end of the spring 11. By pressing the part of the spring 11 located between the terminal 12 and the moving contact 13, the moving contact 13 located at the end of the spring 11 moves in position as the spring 11 deforms, thereby realizing the switching of the moving contact 13 between a first position and a second position.
[0079] In this configuration, one of the first and second positions of the moving contact 13 can be in contact with the stationary contact 60 of the switch, in which case the switch is in the ON state. Conversely, the other position is separate from the stationary contact 60, in which case the switch is in the OFF state. Thus, as the moving contact 13 moves between the first and second positions, the switch is switched between the ON and OFF states.
[0080] Based on the structural arrangement of the spring assembly 1, when the spring assembly 1 is used as a switch, the position of the moving contact 13 can be changed by designing a transition member 4 in the switch to act on the elastic segment 112 to deform it (for example, the transition member 4 presses against the elastic segment 112 to deform it). Compared with the rocker switch where the transition member must drive the rocker to swing to change the position of the moving contact, the operation method of the spring assembly 1 provided in this embodiment of the invention allows the longitudinal dimensions (i.e., thickness) of both the transition member 4 and the spring 11 to be designed to be smaller, which is beneficial to significantly reduce the thickness of the switch and to manufacture an ultra-thin switch. In addition, since the terminal connection segment 111 is fixedly connected to the spring 11, the wiring terminal 12 and the moving contact 13 are always electrically connected during the change of the position of the moving contact 13, and there is no arcing problem caused by the rocker jumping of the rocker switch.
[0081] Appendix Figure 2 An example of the structure of a spring 11 is shown in the attached figure. Figure 2 As shown, the spring 11 includes: a terminal connection section 111, one or two elastic sections 112, and one or two contact connection sections 113.
[0082] The number of elastic segments 112 and contact connection segments 113 are the same and they correspond one-to-one. For example, when the switch is designed as a single-pole single-control switch, both elastic segments 112 and contact connection segments 113 can be set to one and located on one side of terminal connection segment 111. Of course, it is also feasible to set two elastic segments 112 and two contact connection segments 113 and arrange them symmetrically on both sides of terminal connection segment 111. In this case, a moving contact 13 can be set on only one of the contact connection segments 113. For example, when the switch is designed as a single-pole double-control switch, both elastic segments 112 and two contact connection segments 113 are set to two and arranged symmetrically on both sides of terminal connection segment 111, and each contact connection segment 113 is provided with a moving contact 13 (see [reference needed] for this case). Figure 2 ).
[0083] In this configuration, the first end of the elastic segment 112 is connected to one end of the terminal connection segment 111, and the second end of the elastic segment 112 is connected to the corresponding contact connection segment 113. For example, when two elastic segments 112 and two contact connection segments 113 are provided, the first ends of the two elastic segments 112 are each connected to the opposite ends of the terminal connection segment 111, thereby placing the two elastic segments 112 on both sides of the terminal connection segment 111. The second ends of the two elastic segments 112 are each connected to the corresponding contact connection segment 113 to accommodate a two-way switch.
[0084] In terms of application, the terminal connection section 111 is used to connect with the wiring terminal 12; the elastic section 112 can be pressed and deformed, so that the moving contact 13 moves between a first position and a second position; the contact connection section 113 is used to connect with the moving contact 13.
[0085] The terminal 12 is fixedly connected by the terminal connecting section 111 located in the middle of the spring piece 11, and the moving contact 13 is fixedly connected by the contact connecting sections 113 located at both ends of the spring piece 11. In this way, by pressing the elastic section 112 located between the terminal 12 and the moving contact 13, the elastic section 112 can undergo elastic deformation, thereby driving the moving contact 13 to move between the first position and the second position.
[0086] For the spring 11, its elastic segment 112, terminal connection segment 111 and contact connection segment 113 can be connected in various ways, as long as the three have high and reliable connection strength. For example, this includes but is not limited to integral molding connection, welding, bonding and other connection methods.
[0087] The integral molding connection method has the advantages of high connection strength, strong structural stability and simple manufacturing process. As an example, the spring piece 11 provided in the embodiment of the present invention is prepared by integral molding process.
[0088] For example, a one-piece spring sheet 11 can be formed by stamping, bending, and cutting a highly elastic metal sheet. This metal sheet can be a copper sheet, which gives the spring sheet 11 excellent elasticity, electrical conductivity, and thermal conductivity.
[0089] The two elastic segments 112 of the spring piece 11 are located on both sides of the terminal connection segment 111. In this way, after the terminal connection segment 111 is connected to the terminal 12, the two elastic segments 112 are suspended relative to the terminal 12 to ensure good elasticity.
[0090] When pressed, the two elastic segments 112 undergo elastic deformation, and then move in the up and down direction relative to the terminal connection segment 111, so that the moving contact 13 switches between the first position and the second position.
[0091] Understandably, one of the first and second positions of the moving contact 13 involved here is on top and the other is on the bottom.
[0092] The thickness, width, and length of the spring 11 can be adaptively determined based on the elastic force and shape memory function of the spring 11 (i.e., the ability of the spring 11 to quickly return to its initial position after the pressure is released).
[0093] Specifically, the length of the flexible segment 112 (i.e., the dimension of the flexible segment 112 from its first end to its second end) can be determined according to the specific switch type to adapt the arrangement of the moving contact 13 inside the switch. For example, if the terminal 12 is located in the middle of the switch, and the moving contact 13 and the stationary contact 60 are located on both sides of the switch, the length of the flexible segment 112 is sufficient to form a connection between the moving contact 13 and the terminal 12, and to extend to the side of the switch.
[0094] In some examples, there is an angle between the elastic segment 112 and the terminal connection segment 111, which ranges from 120° to 180°, for example, including but not limited to: 120°, 130°, 140°, 150°, 160°, 170°, 180°, etc.
[0095] See Figure 2 When the included angle between the elastic segment 112 and the terminal connection segment 111 is 180°, both are arranged in the horizontal direction and are located in the same horizontal plane.
[0096] See Figure 3 When the angle between the elastic segment 112 and the terminal connection segment 111 is less than 180° and greater than or equal to 120°, the elastic segment 112 is arranged at an angle relative to the terminal connection segment 111, and the elastic segment 112 is located above the terminal connection segment 111.
[0097] In some examples, the angle between the elastic segment 112 and the terminal connection segment 111 can be less than 180° and greater than or equal to 120°. In this way, the elastic segment 112 is easier to be driven to undergo elastic deformation, and at the same time, it can obtain a large elastic potential energy during deformation. This is beneficial to improve the action force of the moving contact 13 and is more advantageous in avoiding arcing.
[0098] In some examples, both the contact connection segment 113 and the resilient segment 112 are arranged horizontally and are located in the same horizontal plane (not shown in the figure). For example, the terminal connection segment 111, the resilient segment 112, and the contact connection segment 113 are all located in the same horizontal plane.
[0099] In other examples, see Figure 2 and Figure 3 The contact connection section 113 includes a guide section 1131 and a connecting contact section 1132 connected to each other. The guide section 1131 is arranged at an angle relative to the elastic section 112, such that the connecting contact section 1132 is located above or below the elastic section 112.
[0100] Taking the spring assembly 1 used in the switch as an example, the "upper" in the up and down directions refers to the direction closer to the panel 3, and the "lower" refers to the direction closer to the base 2.
[0101] Guide section 1131 can be arranged at an angle downward relative to elastic section 112 (see...) Figure 2 It can also be arranged at an angle upwards (see...). Figure 3 By tilting the guide section 1131, the connecting contact section 1132 is positioned above or below the elastic section 112. Thus, when the moving contact 13 is connected to the connecting contact section 1132, the moving contact 13 is positioned accordingly above or below the elastic section 112 to accommodate different types of switches.
[0102] For example, for normally closed switches, combined with Figure 2 It can be seen that the moving contact 13 is located below the elastic section 112. For a normally open switch, combined with... Figure 3 It can be seen that by positioning the moving contact 13 above the elastic segment 112, the above-mentioned orientation of the moving contact 13 can be adapted to different types of switches, ensuring that sufficient contact pressure is obtained between the moving contact 13 and the stationary contact 60.
[0103] In some examples, the connecting contact segment 1132 is arranged horizontally, so that the moving contact 13 is also arranged horizontally accordingly. When the stationary contact 60 in the switch is also arranged horizontally, the moving contact 13 and the stationary contact 60 can make complete ground-to-ground contact, increasing the contact area and obtaining a larger contact pressure.
[0104] The elastic segment 112 can be a strip with a uniform width or a strip with varying widths. The length direction of the spring piece 11 refers to the distribution direction from the contact connection segment 113 to the terminal connection segment 111; the width direction of the spring piece 11 refers to the direction that is perpendicular to its length direction and extends in the horizontal plane.
[0105] In some examples, the width of the elastic segment 112 is inconsistent, as shown in the attached figure. Figure 2 As shown, the elastic segment 112 includes: a first elastic segment 1121 and a second elastic segment 1122 connected to each other, one end of the first elastic segment 1121 away from the second elastic segment 1122 is connected to the terminal connection segment 111, and one end of the second elastic segment 1122 away from the first elastic segment 1121 is connected to the contact connection segment 113.
[0106] From the terminal connection section 111 to the second elastic section 1122, the width of the first elastic section 1121 gradually decreases, and the minimum width of the first elastic section 1121 is equal to the width of the second elastic section 1122.
[0107] By making the width of the first elastic segment 1121 longer near the terminal connection segment 111 and gradually decreasing in width away from the terminal connection segment 111, the fatigue resistance between the elastic segment 112 and the terminal connection segment 111 can be improved. This is because the position of the terminal connection segment 111 is fixed, while the elastic segment 112 frequently deforms and displaces relative to the terminal connection segment 111. By increasing the width at this position, the frequent displacement of the elastic segment 112 can be accommodated, thus preventing irreversible hard deformation.
[0108] By making the width of the second elastic segment 1122 equal to the minimum width of the first elastic segment 1121, it is beneficial to improve the elastic deformation capacity of the second elastic segment 1122, giving it a higher deformation amount.
[0109] When the spring assembly 1 is applied in a switch, the transition piece 4 of the switch can abut against the second elastic segment 1122. The second elastic segment 1122 is, for example, a sheet with a uniform width. The width of the second elastic segment 1122 is designed to have good elastic deformation capability and to be able to adapt to the limited space inside the switch.
[0110] For the terminal block 12, which is connected to the terminal connection section 111 of the spring 11, the connection methods between the two include but are not limited to: welding, snap-fit, riveting, etc. Among them, snap-fit and riveting are easy to disassemble, which helps to simplify the assembly process of the terminal block 12 and facilitates maintenance or replacement.
[0111] For example, terminal 12 is snapped into terminal connection section 111, as shown in the attached diagram. Figure 1 and attached Figure 2As shown, the terminal connection section 111 includes a horizontal connection section 1111 and a vertical snap-fit section 1112, wherein the vertical snap-fit section 1112 is connected to one side of the horizontal connection section 1111 that is distributed along its width direction.
[0112] The horizontal connecting section 1111 is used to connect with the elastic section 112, and the vertical snap-fit section 1112 is used to snap-fit with the terminal block 12. For example, the terminal block 12 is provided with a snap-fit hole, and the vertical snap-fit section 1112 is inserted into and snap-fitted into the snap-fit hole on the terminal block 12.
[0113] Furthermore, as shown in the appendix Figure 1 and attached Figure 2 As shown, the terminal connection section 111 may also include a positioning section 1113, which is connected to the horizontal connection section 1111 and is located on the same side as the vertical snap-fit section 1112.
[0114] In this way, after the terminal block 12 is connected to the vertical snap-fit section 1112, the upper end of the terminal block 12 abuts against the positioning section 1113, and the lower end of the terminal block 12 can abut against the base 2 in the switch, thus realizing the positioning of the terminal block 12 inside the switch.
[0115] The structure of the moving contact 13 and its connection method with the contact connection section 113 can adopt conventional techniques in the field, and the embodiments of the present invention do not impose specific limitations on this.
[0116] The embodiments of the present invention also relate to the application of any of the spring components 1 shown above in switching electrical devices. When used in switching electrical devices, it is beneficial to significantly reduce their thickness, making them suitable for ultra-thin development.
[0117] According to another aspect of the present invention, a switch is also provided, the switch including any of the above-described spring assembly 1.
[0118] The switch provided in this embodiment of the invention has all the advantages of the above-mentioned spring assembly 1, enabling the switch to be designed as an ultra-thin switch.
[0119] According to the control method, the switch involved in the embodiments of the present invention can be a single-pole single-control switch or a single-pole double-control switch. When the switch is a single-pole single-control switch, the number of moving contacts 13 in the spring assembly 1 is designed to be one; when the switch is a single-pole double-control switch, the number of moving contacts 13 in the spring assembly 1 is designed to be two symmetrical contacts.
[0120] The switches involved in the embodiments of the present invention can be classified according to their normal energization method as either normally closed switches or normally open switches.
[0121] As attached Figure 4 Appendix Figure 5 and appendix Figure 6 As shown, when the switch is a normally closed switch, the moving contact 13 is located below the corresponding stationary contact 60, and the contact pressure between the moving contact 13 and the stationary contact 60 is provided by the spring 11; as shown in the attached figure. Figure 4 Appendix Figure 5 and appendix Figure 7 As shown, when the switch is a normally open switch, the moving contact 13 is located above the corresponding stationary contact 60, and the contact pressure between the moving contact 13 and the stationary contact 60 is provided by the transition member 4.
[0122] Taking a single-pole double-control switch as an example, as shown in the attached diagram. Figure 6 and appendix Figure 7 As shown, it includes a pair of normally closed contacts consisting of a moving contact 13 and a stationary contact 60, and a pair of normally open contacts consisting of a moving contact 13 and a stationary contact 60, with the normally closed and normally open contacts located on both sides of the switch.
[0123] Appendix Figure 6 A cross-sectional view of a normally closed single-pole double-control switch is shown below. Figure 7 An example is a cross-sectional view of a normally open single-pole double-control switch. In this embodiment of the invention, if the normally closed contact corresponds to the upturned side of panel 3, it is called a normally closed single-pole double-control switch (see [reference]). Figure 6 Conversely, if the normally open contact corresponds to the upturned side of panel 3, it is called a normally open single-pole double-control switch (see [reference]). Figure 7 ).
[0124] Combination Figure 6 and Figure 7 As can be seen, an exemplary switch, in addition to the aforementioned spring assembly 1, further includes: a base 2, a panel 3, a transition member 4, a swing positioning member 5, and a stationary contact assembly 6. Both the spring assembly 1 and the stationary contact assembly 6 are located inside the base 2, and the moving contact 13 on the spring assembly 1 corresponds to the stationary contact 60 on the stationary contact assembly 6. That is, the moving contact 13 of the spring assembly 1 cooperates with its corresponding stationary contact 60; when they come into contact, the switch is turned on; when they separate, the switch is turned off.
[0125] Combined with appendix Figure 5 As shown, the transition member 4 includes: a transition member body 41 and a driving part 42 located on the side of the transition member body 41. The transition member body 41 is connected to the panel 3 and is also hinged to the base 2. The panel 3 can be pressed and rotated relative to the base 2. The driving part 42 corresponds to the elastic segment 112 of the spring assembly 1. The driving part 42 can act on the corresponding position of the elastic segment 112 to deform it, thereby causing the moving contact 13 to contact or separate from the corresponding stationary contact 60.
[0126] The swing positioning element 5 is connected between the transition body 41 and the base 2. The swing positioning element 5 is configured to stabilize the transition element 4 and the panel 3 as a whole in the closed position and the open position. Here, the closed position refers to one position of the transition element 4 and the panel 3 when the switch is closed; and the open position refers to another position of the transition element 4 and the panel 3 when the switch is open.
[0127] Panel 3 has two pressing sides. In the closed and open states of the switch, one pressing side is in an upward-curved state, and the other pressing side is in a downward-curved state. When it is necessary to switch the switch between the open and closed states, simply press the upward-curved pressing side of panel 3.
[0128] The switch provided in this embodiment of the invention, when the panel 3 is pressed to rotate around the base 2, since the panel 3 is connected to the transition member body 41, the rotation of the panel 3 can drive the transition member 4 to rotate, thereby causing the driving part 42 on the side of the transition member 4 to move upward or downward. When the driving part 42 moves downward, it can drive the elastic segment 112 on the corresponding side of the spring piece 11 to move downward, thereby causing the moving contact 13 to move downward. Thus, for a normally closed switch, the downward movement of the moving contact 13 separates it from the stationary contact 60, realizing the disconnection of the normally closed contact; and for a normally open switch, the downward movement of the moving contact 13 contacts it with the stationary contact 60, realizing the connection of the normally open contact.
[0129] Understandably, for a single-control switch, a set of drive units 42 can be provided only on one side of the transition body 41; for a double-control switch, a set of drive units 42 can be provided on each side of the transition body 41, so that one set of drive units 42 on each side moves upward and the other set moves downward.
[0130] For each set of drive units 42 mentioned above, the number of drive units 42 can be designed to be one, two, or more. In some examples, the drive unit 42 can be designed as a drive rib.
[0131] When the switch switches between the closed and open states, panel 3 and transition piece 4 rotate clockwise or counterclockwise, thereby switching between the closed and open positions. By providing a swing positioning piece 5, panel 3 and transition piece 4 can maintain a stable position when rotated to the closed and open positions, thereby ensuring the stability of the interaction between moving contact 13 and stationary contact 60.
[0132] The following combination Figure 10 and attached Figure 11 The working principle of a switch including spring assembly 1 is described by way of example:
[0133] Appendix Figure 10 Example A1 illustrates the structure of a normally closed single-pole double-control switch in the normally closed contact closed state. As shown in A1, the panel 3 and the transition piece 4 are stabilized in the closed position under the action of the swing positioning piece 5 (the right side is in an upward state, and the left side is in a downward state). At this time, the drive part 42 located on the left side of the transition piece 4 presses against the left elastic segment 112 of the spring piece 11, and the moving contact 13 on the left side separates from the stationary contact 60 on the left side under the action of the transition piece 4, and the normally open contact on the left side is in the open state. Furthermore, the drive part 42 located on the right side of the transition piece 4 separates from the right elastic segment 112 of the spring piece 11, and the moving contact 13 on the right side contacts the stationary contact 60 on the right side under the elastic force of the right elastic segment 112 of the spring piece 11, and the normally closed contact on the right side is in the closed state, and they remain stable under the action of the swing positioning piece 5.
[0134] Appendix Figure 10 Example A2 illustrates the structure of a normally closed single-pole double-throw switch when the normally closed contact switches from a closed state to an open state. As shown in A2, pressing the right side of panel 3 causes panel 3 and transition piece 4 to rotate clockwise under the pressure of the pressing force. When rotated to a certain position, the drive part 42 on the left side of transition piece 4 presses against the left elastic segment 112 of spring piece 11, and the drive part 42 on the right side of transition piece 4 presses against the right elastic segment 112 of spring piece 11. The moving contact 13 on the left moves upward and remains separated from the stationary contact 60 on the left, while the moving contact 13 on the right moves downward and remains connected to the stationary contact 60 on the right (based on the elastic force of the right elastic segment 112). Although the normally closed contact on the right is in the connected state and the normally open contact on the left is in the open state, this state is unstable.
[0135] Appendix Figure 10Example A3 illustrates the structure of a normally closed single-pole double-control switch in the normally closed contact open state. As shown in A3, when the right side of panel 3 is pressed further, panel 3 and transition piece 4 rotate clockwise under the action of the pressing force until panel 3 and transition piece 4 quickly pass the critical point under the action of swing positioning piece 5 and stop in a stable state. Thus, panel 3 and transition piece 4 are stabilized at the open position under the action of swing positioning piece 5 (its left side is in an upward state, and its right side is in a downward state). At this time, the driving part 42 located on the right side of transition piece 4 presses against the right elastic segment 112 of spring piece 11, and the moving contact 13 on the right side separates from the stationary contact 60 on the right side under the action of transition piece 4, and the normally closed contact on the right side is in the open state. Furthermore, the drive section 42 located on the left side of the transition member 4 is separated from the left elastic segment 112 of the spring piece 11. The moving contact 13 on the left side contacts the stationary contact 60 on the left side under the elastic force of the left elastic segment 112 of the spring piece 11. The normally open contact on the left side is in the closed state, and they remain stable under the action of the swing positioning member 5.
[0136] It is evident that normally closed switches have at least the following advantages:
[0137] (1) The contact pressure between the moving contact 13 and the stationary contact 60 is provided by the elastic force of the elastic segment 112 on the corresponding side of the spring sheet 11, which makes the contact pressure between the moving contact 13 and the stationary contact 60 stable and controllable.
[0138] (2) The separation between the moving contact 13 and the stationary contact 60 is provided by the pressing external force. When the moving contact 13 separates from the stationary contact 60, the driving part 42 on the transition member 4 pushes it open instantly. The separation speed is fast. Compared with the traditional rocker switch, which is prone to arcing due to the contact pressure changing from large to small, the normally closed switch provided in this embodiment of the invention significantly reduces the arcing phenomenon.
[0139] (3) The spring piece 11 is located below the stationary contact 60, and uses its own elasticity to make the moving contact 13 and the stationary contact 60 make stable contact. It can be seen that the elastic segment 112 of the spring piece 11 has a large deformation capacity, which gives it a large operating force. This is particularly beneficial to improving the contact stability and contact speed between the moving contact 13 and the stationary contact 60, which not only ensures the reliability of the switch, but also further reduces the arcing phenomenon.
[0140] The following combination Figure 11 The working principle of a switch including spring assembly 1 is described by way of example:
[0141] Appendix Figure 10Example B1 illustrates the structure of a normally open single-pole double-control switch in the normally open contact open state. As shown in B1, panel 3 and transition piece 4 are stabilized in the open position under the action of swing positioning piece 5 (the right side is tilted upwards, and the left side is tilted downwards). At this time, the drive part 42 located on the left side of transition piece 4 presses against the left elastic segment 112 of spring piece 11, and the moving contact 13 on the left side contacts the stationary contact 60 on the left side under the action of transition piece 4, and the normally closed contact on the left side is in the closed state. Additionally, the drive part 42 located on the right side of transition piece 4 contacts the right elastic segment 112 of spring piece 11, and the moving contact 13 on the right side separates from the stationary contact 60 on the right side under the elastic force of the right elastic segment 112 of spring piece 11, and the normally open contact on the right side is in the open state, and they remain stable under the action of swing positioning piece 5.
[0142] Appendix Figure 10 Example B2 illustrates the structure of a normally open single-pole double-control switch when the normally closed contact switches from an open state to a closed state. As shown in B2, pressing the right side of panel 3 causes panel 3 and transition piece 4 to rotate clockwise under the pressure. When rotated to a certain position, the drive part 42 on the left side of transition piece 4 presses against the left elastic segment 112 of spring piece 11, and the drive part 42 on the right side of transition piece 4 presses against the right elastic segment 112 of spring piece 11. The moving contact 13 on the left moves upward and is separated from the stationary contact 60 on the left, while the moving contact 13 on the right moves downward and remains separated from the stationary contact 60 on the right. Although the normally closed contact on the left is in an open state and the normally open contact on the right is in an open state, this state is unstable.
[0143] Appendix Figure 10 Example B3 illustrates the structure of a normally open single-pole double-control switch in the normally open contact closed state. As shown in B3, when the right side of panel 3 is pressed further, panel 3 and transition piece 4 rotate clockwise under the action of the pressing force until panel 3 and transition piece 4 quickly pass the critical point under the action of swing positioning piece 5 and stop in a stable state. Thus, panel 3 and transition piece 4 are stabilized in the closed position under the action of swing positioning piece 5 (its left side is in an upward state, and its right side is in a downward state). At this time, the driving part 42 located on the right side of transition piece 4 presses against the right elastic segment 112 of spring piece 11, and the moving contact 13 on the right side contacts the stationary contact 60 on the right side under the action of transition piece 4, and the normally open contact on the right side is in the closed state. Furthermore, the drive section 42 located on the left side of the transition member 4 is still in contact with the left elastic segment 112 of the spring piece 11. The moving contact 13 on the left side is separated from the stationary contact 60 on the left side under the elastic force of the left elastic segment 112 of the spring piece 11. The normally closed contact on the left side is in the open state, and they remain stable under the action of the swing positioning member 5.
[0144] As can be seen, for a normally open switch, the contact pressure between the moving contact 13 and the stationary contact 60 is provided by the driving part 42 on the transition member 4 pressing down against the spring 11, and the separation between the moving contact 13 and the stationary contact 60 is provided by the elastic force of the elastic segment 112 on the corresponding side of the spring 11.
[0145] In this embodiment of the invention, the driving part 42 acts on the elastic segment 112 in the following ways: the driving part 42 presses down on the elastic segment 112, and optionally the driving part 42 pulls up on the elastic segment 112.
[0146] For example, the driving part 42 can press down on the elastic segment 112 by having the bottom end of the driving part 42 directly abut against the surface of the elastic segment 112. In this way, when the driving part 42 moves downward, the elastic segment 112 is pressed down and deformed. When the driving part 42 moves upward, the elastic segment 112 is reset and can be separated from the elastic segment 112.
[0147] The upward pulling mechanism of the drive unit 42 on the elastic segment 112 can be implemented, for example, by connecting the bottom end of the drive unit 42 to the elastic segment 112 via a movable connector. In this way, when the drive unit 42 moves downward, the elastic segment 112 is compressed and deformed; when the drive unit 42 moves upward, the elastic segment 112 returns to its original position and can move upward together with the drive unit 42. Exemplarily, the movable connector can have a hook, clamp, or similar device with a limiting cavity, within which the elastic segment 112 can movably reside.
[0148] Based on the above description of the working principles of normally closed and normally open switches, in some examples, such as those shown in the appendix... Figure 10 The normally closed switch shown can be implemented by having the bottom end of the drive unit 42 directly abut against the surface of the elastic segment 112. (See attached diagram) Figure 11 The normally closed switch shown can be implemented by connecting the bottom end of the drive unit 42 to the elastic section 112 via a movable connector, which facilitates the rapid separation and positioning of the moving contact 13.
[0149] As mentioned above, the transition piece 4 can be stabilized in the on and off positions under the action of the swing positioning piece 5. Two swing positioning pieces 5 are symmetrically arranged in the switch, one of which is located below the upturned side of the panel 3, and the other is located below the drooping side of the panel 3.
[0150] When the switch is in the normally closed or normally open state, one of the swing positioning members 5 has an upward pulling force on one side of the transition member 4, and the other swing positioning member 5 has a downward pulling force on the other side of the transition member 4. When there is no external force, the upward pulling force and the downward pulling force are balanced, so that the positions of the swing positioning member 5 and the transition member 4 are fixed.
[0151] The swing positioning component 5 can be designed in various structural types, as long as it meets the following conditions: it can change its position accordingly with the rotation of the transition component 4 to adapt to the position change of the transition component 4, and it can achieve a stable state at two extreme positions to achieve self-fixation, thereby positioning the position of the transition component 4. This self-fixation can only be released by an external force of a certain magnitude.
[0152] Understandably, the stable contact state and stable separation state between the moving contact 13 and the stationary contact 60 are controlled by the two stable states of the swing positioning element 5, thereby achieving the purpose of switching on and off.
[0153] Examples of swing positioning elements 5 that meet the above requirements include, but are not limited to: instantaneous springs, cooperating linkage mechanisms + springs, etc. Considering the miniaturization requirements of the switch, in some examples, the swing positioning element 5 is an instantaneous spring (see...). Figures 5-7 The instantaneous spring, used as the swing positioning component 5, not only fixes the transition component 4 at its extreme positions but also adapts to the lateral layout of the internal components of the switch, facilitating the ultra-thin development of the switch. Furthermore, the instantaneous spring's characteristic of generating instantaneous motion upon being subjected to external force not only improves the speed at which the moving contact 13 and the stationary contact 60 contact or separate but also enhances the tactile feedback when the user presses the panel 3.
[0154] In this embodiment of the invention, the elastic force of the instantaneous spring is much greater than that of the spring plate 11, so that the position of the transition piece 4 and the spring plate 11 can be fixed by the instantaneous spring alone.
[0155] See Figures 5-7 When the swing positioning component 5 is a momentary spring, the first end of the swing positioning component 5 is connected to the side of the base 2, and the second end of the swing positioning component 5 is connected to the side of the transition component 4. The connection between the swing positioning component 5 and the base 2, and between the swing positioning component 5 and the transition component 4, is a fixed connection and / or a movable connection.
[0156] Taking movable connections as an example, they include, but are not limited to, bushing connections, hook and loop connections, etc. For example, the swing positioning part 5 can be connected to the base 2 and the transition part 4 by a bushing connection.
[0157] In some examples, as shown in the appendix Figure 6 and attached Figure 7 As shown, protruding posts are arranged on the sides of the base 2 and the transition piece 4, so that the protruding posts are sleeved in the two ends of the swing positioning piece 5 (i.e., the instantaneous spring), realizing the above-mentioned bushing connection. In this way, the swing positioning piece 5 (i.e., the instantaneous spring) is more adaptable to the rotation process of the transition piece 4, making the pressing operation of the panel 3 smoother.
[0158] During the switching process of the normally open or normally closed contact of the switch, both the swing positioning element 5 and the transition element 4 are in an unstable state. At this time, the swing positioning elements 5 (i.e., instantaneous springs) located on both sides of the transition element 4 can be in a horizontal state. That is, the central axes of the two protrusions on the side of the base 2 and the side of the transition element 4 coincide. At this time, both ends of the swing positioning element 5 are squeezed, causing the swing positioning element 5 to deform and become unstable.
[0159] In this embodiment of the invention, a transition member 4 is used to transmit the pressing pressure of the panel 3 to the spring piece 11. The transition member 4 includes a transition member body 41 and two driving parts 42 located on both sides of the transition member body 41. Exemplarily, the top end of the driving part 42 is connected to the bottom side of the transition member body 41, and the bottom end of the driving part 42 is used to abut against the second elastic segment 1122 of the spring piece 11.
[0160] In some examples, the transition body 41 is a flat plate structure, such as a rectangular plate. The transition body 41 is fixedly connected to the panel 3. For example, the connection methods between the two include, but are not limited to: snap-fit, riveting, welding, bonding, integral molding connection, etc.
[0161] In some examples, as shown in the appendix Figure 8 As shown, the transition body 41 is snapped onto the panel 3. For example, a first snap-fit structure 411 is arranged on the first and second opposite sides of the transition body 41, and a second snap-fit structure 31 is arranged at the corresponding position on the bottom of the panel 3. One of the first snap-fit structure 411 and the second snap-fit structure 31 is a buckle, and the other is a snap hole. The buckle and the snap hole are matched and snapped together, thereby realizing the snap-fit of the transition body 41 onto the panel 3.
[0162] For example, the first snap-fit structure 411 is a snap hole (the number of snap holes on the same side can be one, two, three or more), and the second snap-fit structure 31 is a buckle (the number of buckles is the same as the number of snap holes). The distribution direction of the first and second sides of the transition member body 41 is consistent with the distribution direction of the two pressing sides of the panel 3.
[0163] The transition body 41 is also hinged to the base 2, for example, see Figure 5 and combined Figure 9 A pin 412 is connected to the middle of the third and fourth opposite sides of the transition body 41. A bracket 21 with a shaft hole is provided at the corresponding position on the side of the base 2. The pin 412 is rotatably sleeved in the shaft hole, thereby enabling the transition body 41 to be hinged to the base 2. The distribution direction of the third and fourth sides of the transition body 41 is perpendicular to the distribution direction of the first and second sides.
[0164] Understandably, apart from the improved designs adapted to the embodiments of the present invention, such as the second snap-fit structure 31 described above, the main structure of the panel 3 can adopt a panel structure commonly used in the art.
[0165] To increase the interaction area between panel 3 and transition piece 4, and to enable them to rotate synchronously, see [reference needed]. Figure 8 Furthermore, multiple first pressure ribs 32 can be provided at the bottom of panel 3, and the multiple first pressure ribs 32 abut against the corresponding positions on the top of the transition body 41.
[0166] In some examples, the bottom end of the drive portion 42 is used to abut against the top of the second elastic segment 1122 of the spring 11 near the contact connection segment 113, so that the moving contact 13 is driven quickly and reliably. For example, the bottom end of the drive portion 42 is arc-shaped.
[0167] Furthermore, the width of the drive section 42 can be equal to the width of the second elastic segment 1122 of the spring 11, so that the two can fully abut against each other, thereby improving the driving reliability of the transition member 4 on the spring 11.
[0168] The transition body 41 and the drive part 42 can be fixedly connected in various ways, such as integral molding connection, welding, snap-fit, bonding, etc. In some examples, the integral molding connection method is used to connect the transition body 41 and the drive part 42.
[0169] See in some examples Figure 9 The transition component 4 involved in this embodiment of the invention is an integral structural component, that is, an integral structural component is used as the transition component 4.
[0170] In other examples, the transition member 4 of the present invention includes multiple split sub-transition members (not shown in the figure) connected by a rotatable connection. For example, the transition member 4 includes a first sub-transition member and two second sub-transition members symmetrically arranged on both sides of the first sub-transition member. The first sub-transition member is fixedly connected to the panel 3 and its middle two sides are hinged to the base 2. The swing positioning member 5 is connected between the side of the first sub-transition member and the side of the base 2. One end of the second sub-transition member is rotatably connected to the base 2, and the other end of the second sub-transition member is rotatably connected to the first sub-transition member. The driving part 42 is disposed at the bottom of the second sub-transition member near the end of the first sub-transition member.
[0171] By setting the transition piece 4 as the aforementioned split structure, it is possible not only to ensure that the pressing force of the button is efficiently transmitted to the spring piece 11, but also to further reduce the swing amplitude of the panel 3 when it is pressed, while ensuring that the transition piece 4 reaches the target stroke, which is conducive to the ultra-thin development of the switch.
[0172] In this embodiment of the invention, the base 2 accommodates and fixes the spring assembly 1, the stationary contact assembly 6, etc. The base 2 can be designed as an integral structural component, that is, the base 2 is formed by a single integral structural component. Alternatively, the base 2 can be composed of multiple separate structural components. Examples are given below:
[0173] In some examples, as shown in the appendix Figure 6 and attached Figure 7 As shown, base 2 is composed of multiple separate structural components, as illustrated in the attached diagram. Figure 1 As shown, the base 2 includes a seat body 201 and a cover body 202. The seat body 201 has a receiving cavity 20 to accommodate the spring assembly 1 and the stationary contact assembly 6.
[0174] The cover 202 is detachably connected to the seat 201 and covers the upper port of the accommodating cavity 20. The opposite first and second sides of the cover 202 are hinged to the two sides of the transition member 4. The opposite third and fourth sides of the cover 202 are each connected to a swing positioning member 5.
[0175] The drive part 42 of the transition piece 4 passes through the cover 202 and extends into the accommodating cavity 20 to interact with the spring piece 11. That is, there is a through hole at the corresponding position on the cover 202, and the drive part 42 on the transition piece 4 passes through the through hole and extends into the accommodating cavity 20 of the seat 201.
[0176] The implementation methods for the hinged connection between the cover 202 and the transition piece 4, and the connection between the cover 202 and the swing positioning piece 5, can be found in the above description of the connection method between the transition piece body 41 and the base 2, and the connection method between the swing positioning piece 5 and the base 2. They will not be repeated here.
[0177] By designing the base 2 as a detachable connection between the seat 201 and the cover 202, the assembly of the internal components of the switch becomes more convenient and efficient.
[0178] Furthermore, as shown in the appendix Figure 7 As shown, the bottom of the cover 202 may also be provided with a plurality of second pressure ribs 2021. The plurality of second pressure ribs 2021 are used to abut against the top of the spring assembly 1 and / or the stationary contact assembly 6, so as to further position the spring assembly 1 and / or the stationary contact assembly 6.
[0179] For example, the top of the terminal connection section 111 of the spring 11 can abut against the second pressure rib 2021 at the corresponding position on the bottom of the cover 202.
[0180] For the stationary contact assembly 6, it is understood that it includes connected terminals and a contact piece with a stationary contact 60, such that the top of the contact piece abuts against the second pressure rib 2021 at a corresponding position on the bottom of the cover 202.
[0181] The cover 202 can be detachably connected to the base 201 in a variety of ways, such as including but not limited to: snap-fit, riveting, screw connection, etc.
[0182] In other examples, see Figure 10 and Figure 11 The base 2 is an integral structural component. The base 2 includes a receiving cavity 20 to accommodate the spring assembly 1 and the stationary contact assembly 6. The opposite first and second sides of the receiving cavity 20 are hinged to the two sides of the transition member 4. The opposite third and fourth sides of the receiving cavity 20 are each connected to a swing positioning member 5.
[0183] Specifically, the middle of the first inner wall and the second inner wall of the accommodating cavity 20 are hinged to the middle of the corresponding side of the transition member 4, and the third inner wall and the fourth inner wall of the accommodating cavity 20 are each connected to a swing positioning member 5.
[0184] The integrated structure design of base 2 also enables the various components inside the switch to work together.
