In order to make the technical solutions and advantages of the present invention clearer, the following will describe the embodiments of the present invention in further detail with reference to the accompanying drawings.

The switch is common electric current on-off device, and at present, the switch is usually designed for wane formula or pendulum piece formula, and in these two types of switches, the transition piece all passes through compression spring and connects drive structure to the realization dials to wane or pendulum piece.

However, the currently known rocker switch or swing sheet switch has limitations on its dialing performance, for example, the rocker switch is easy to generate an arc phenomenon when dialing, the swing sheet switch is easy to appear in a false position when dialing, and meanwhile, if the side edge of the panel is pressed for dialing, the dialing may be disabled.

In order to solve the technical problem in the related art, an embodiment of the present invention provides a switch, as shown in fig. 1 to 3, including: panel 1, base 2, transition component 3, elastic positioning piece 4, movable contact component 5 and fixed contact component 6.

As shown in fig. 3, the movable contact assembly 5 includes: the spring plate 51, the wiring terminal 52 connected and fixed in the middle of the spring plate 51, and the movable contact 53 connected and fixed at the end of the spring plate 51; the movable contact assembly 5 and the stationary contact assembly 6 are both located inside the base 2, and the movable contact 53 corresponds to the stationary contact 60 on the stationary contact assembly 6.

The panel 1 can be pressed and rotated relative to the base 2, and the transition component 3 is connected to the panel 1 and hinged to the base 2; the transition assembly 3 includes a driving rib 300, and the transition assembly 3 can be pressed by the panel 1 to act on the corresponding position of the elastic sheet 51 through the driving rib 300 to deform the same, so that the movable contact 53 is contacted with or separated from the fixed contact 60.

As can be seen from fig. 3 and 4, two opposite sides of the transition component 3 are respectively provided with a through hole 310, the elastic positioning element 4 penetrates through the through hole 310, and two ends of the elastic positioning element 4 respectively abut against the base 2, so that one of the two elastic positioning elements 4 located at two sides of the transition component 3 is extruded to be concave, and the other one is extruded to be convex.

The embodiment of the utility model provides a switch has following improvement for traditional rocker switch and pendulum piece switch at least:

firstly, a movable contact assembly 5 with an improved structure is used, wherein a terminal 52 is fixed at the middle part of the elastic sheet 51, a movable contact 53 is fixed at the end part of the elastic sheet 51, and the part of the elastic sheet 51 between the terminal 52 and the movable contact 53 is pressed by the driving rib 300 to be elastically deformed, so that the position change of the movable contact 53 is realized, and the movable contact 53 is contacted with or separated from the fixed contact 60.

With the wane in the changeover member must drive the wane swing in order to realize the position change of movable contact to and in the swing piece switch the changeover member must drive the swing piece swing in order to realize the position change of movable contact and compare, the embodiment of the utility model provides a this operation mode of movable contact subassembly 5, because terminal linkage segment 511 fixed connection is in shell fragment 51, in the change of movable contact 53 position, binding post 52 and movable contact 53 electric connection all the time, can not have the wane switch because of the wane arc problem that beats and arouse, also can not have the swing piece switch because of what the swing piece swing arouses dials the virtual bit problem, and then make the utility model provides a dial the performance and dial and feel of switch and all can promote. Moreover, this also facilitates that the longitudinal dimensions of both the transition member 3 and the spring 51 can be designed to be small, which facilitates that the switch is designed to be ultra-thin.

Secondly, the arrangement of the elastic positioning pieces 4 in the switch is improved, the two elastic positioning pieces 4 are symmetrically arranged at two opposite sides of the transition component 3, wherein the elastic positioning pieces 4 penetrate through the holes 310, and two ends of the elastic positioning pieces 4 are respectively abutted against the base 2, so that one of the two elastic positioning pieces 4 is extruded to be concave, and the other one is extruded to be convex. The elastic positioning pieces 4 are horizontally arranged in the switch, the distribution direction from the upwarp side to the drooping side of the panel 1 is defined as a first direction, and then the two elastic positioning pieces 4 are horizontally arranged in the switch along a second direction perpendicular to the first direction.

It will be appreciated that two resilient locating members 4 are provided on either side of the transition member 3, one of which is also located below the upturned side of the panel 1 and the other of which is located below the downturned side of the panel 1. When pressing panel 1 and rotating with drive transition subassembly 3, transition subassembly 3 rotates to the horizontality, two elastic positioning element 4 that are located its both sides are also corresponding changes for the horizontality, because elastic positioning element 4 is extruded all the time, so it is unstable under the horizontality, thus, only need to continue to press panel 1 hard, then elastic positioning element 4 corresponding to this side of pressing will be recessed, and the elastic positioning element 4 of opposite side then epirelief, and then promote transition subassembly 3 to accomplish rapidly and dial, and simultaneously, elastic positioning element 4, transition subassembly 3 and panel 1's position converts balanced state into by unbalance state.

It can be seen that, when the switch is in a normally closed state or a normally open state, the convex elastic positioning member 4 has an upward pulling force on one side of the transition assembly 3, and the concave elastic positioning member 4 has a downward pressing force on the other side of the transition assembly 3, and when no external force is applied, the upward pulling force and the downward pressing force are balanced, so that each component in the switch is stable in the normally closed state or the normally open state. When the switch state needs to be switched, the elastic positioning piece 4 is instable instantly only by pressing the upwarping side of the panel 1, so that the transition component 3 is promoted to change the position, and the instant dialing effect is achieved.

All utilize vertical arrangement to realize the level or vertically dial in the spring at switch middle part in rocker switch and pendulum piece switch and compare, the embodiment of the utility model provides a arrange elastic positioning element 4 at the both sides level of switch and realize dialling transition subassembly 3 in the twinkling of an eye, should dial the mode more directly and can effectively increase pressing effective area of panel 1, the user presses panel 1 in multiple position, for example, presses at panel 1's lateral margin, all can realize effectively dialling transition subassembly 3. Particularly, the elastic positioning element 4 penetrates through the hole 310, two ends of the elastic positioning element 4 are respectively abutted to the base 2, and the wall of the hole 310 and the wall of the base 2 can both play a role in supporting the elastic positioning element 4, so that the dialing stability and reliability of the elastic positioning element 4 to the transition component 3 are improved.

In some examples, the embodiment of the utility model provides an elastic positioning element 4 is instantaneous spring, and it has simple structure, and the volume is less, and instantaneous advantage such as effectual because instantaneous spring has the characteristics that produce the instantaneous motion after receiving external force, and this speed when not only does benefit to and improves movable contact 53 and stationary contact 60 contact or separation still does benefit to and promotes the user and presses feeling when panel 1.

The embodiment of the utility model provides an in, the elasticity of instantaneous spring self is far greater than the elasticity of shell fragment 51 for the rigidity of transition subassembly 3 can only be controlled by instantaneous spring.

When elastic positioning element 4 is the instant spring, it can adopt multiple mode to arrange in the switch, has spliced pole 201 on the base 2 illustrated in fig. 5, and corresponding spliced pole 201 is located to the cover respectively in the both ends of elastic positioning element 4, for example, spliced pole 201 sets up on the lateral wall of casting die 22 of base 2.

For example, the connecting column 201 may be a cylinder or a polygonal prism, and the outer diameter of the connecting column is matched with the inner diameter of the elastic positioning member 4.

Through the both ends cover of elastic positioning piece 4 locate corresponding spliced pole 201 on for elastic positioning piece 4 butt can also be spacing between two spliced poles 201 in base 2, improves elastic positioning piece 4's positional stability.

When the elastic positioning element 4 is a snap spring, the length of the elastic positioning element 4 must be greater than the distance between the two connecting posts 201 at the two ends, so that after the elastic positioning element 4 is assembled in place, one of the elastic positioning elements 4 can be pressed into an upward convex shape (i.e., an upward convex arc shape), and the other elastic positioning element 4 can be pressed into a downward concave shape (i.e., a downward concave arc shape).

In some examples, as shown in fig. 5, the base 2 has abutting blocks 202, and two ends of the elastic positioning element 4 abut against the corresponding abutting blocks 202 respectively; wherein, the abutting block 202 is contacted with partial end surface of the corresponding end of the elastic positioning piece 4. For example, the abutment block 202 is provided on a side wall of the holding member 22 of the base 2.

The contact area between the elastic positioning piece 4 and the base 2 can be reduced by arranging the abutting block 202, so that the friction loss generated when the elastic positioning piece 4 deforms in an upward convex mode or a downward concave mode is reduced, the action of the elastic positioning piece 4 is smoother, the pressing action of the panel 1 is more smooth, and the purpose of improving the dialing hand feeling is achieved.

In some examples, the vertical cross-sectional area of the abutment block 202 gradually decreases from a first end of the abutment block 202 connected with the base 2 to a second end of the abutment block 202 distal from the base 2. For example, the abutment block 202 may be a triangular block, a trapezoidal block, an arcuate block, or the like.

Through arranging the structure of the abutting block 202 as above, not only a small contact area between the abutting block and the elastic positioning piece 4 can be ensured, but also a large connection area between the abutting block and the base 2 can be ensured, so that the strength of the abutting block is improved, and the problems of extrusion deformation and the like are prevented.

In some examples, as shown in fig. 5 and fig. 6, the base 2 has a connecting column 201 and an abutting block 202, wherein two opposing sides of the connecting column 201 are respectively disposed with one abutting block 202, so that two sides of the end of the elastic positioning member 4 respectively abut against the corresponding abutting blocks 202 while the end of the connecting column 201 is sleeved with the end of the elastic positioning member. For example, the connecting column 201 and the abutting block 202 are provided on the side wall of the pressing member 22 of the base 2.

For the movable contact assembly 5 involved in the switch provided by the embodiment of the present invention, referring to fig. 8, a structure of the elastic sheet 51 is illustrated, as shown in fig. 8, the elastic sheet 51 includes: a terminal connection section 511, two spring sections 512, one or two contact connection sections 513. First ends of the two elastic segments 512 are respectively connected with two opposite ends of the terminal connection segment 511, so that the two elastic segments 512 are located at two sides of the terminal connection segment 511.

When the number of the contact connection sections 513 is one, the second end of one of the elastic sections 512 may be connected to the contact connection section 513 to be adapted to a single control switch; and, when the number of the contact connection sections 513 is two, the second ends of the two elastic sections 512 may be connected to one contact connection section 513, respectively, to accommodate the dual-control switch.

The connection terminal 52 is fixedly connected through the terminal connection section 511 located in the middle of the elastic sheet 51, and the moving contact 53 is fixedly connected through the contact connection sections 513 located at both ends of the elastic sheet 51, so that the elastic section 512 located between the connection terminal 52 and the moving contact 53 is pressed by the driving rib 300, and the elastic section 512 can be elastically deformed, thereby driving the moving contact 53 to move, so that the moving contact 53 and the stationary contact 60 are contacted or separated.

In some examples, a high-elasticity metal sheet is used, and the spring plate 51 of an integrated structure is formed by performing operations such as stamping, bending, cutting and the like on the high-elasticity metal sheet. The metal sheet may be a copper sheet, which enables the spring plate 51 to have excellent elasticity, electrical conductivity and thermal conductivity.

In some examples, the elastic section 512 and the terminal connection section 511 have an included angle therebetween in a range of 120 ° to 180 °, for example, this includes but is not limited to: 120 °, 130 °, 140 °, 150 °, 160 °, 170 °, 180 °, etc.

When the included angle between the elastic section 512 and the terminal connection section 511 is less than 180 ° and greater than or equal to 120 °, the elastic section 512 is obliquely disposed above the terminal connection section 511. In this way, the elastic section 512 is more easily driven to be elastically deformed, and can obtain a larger elastic potential energy when being deformed.

In other examples, referring to fig. 9, the contact connecting section 513 includes: a connected guide section 5131 and a connection contact section 5132, the guide section 5131 being arranged obliquely with respect to the spring section 512 such that the connection contact section 5132 is located above or below the spring section 512.

The guide section 5131 may be disposed obliquely downward or obliquely upward with respect to the elastic section 512, and by obliquely disposing the guide section 5131, the connection contact section 5132 is located above or below the elastic section 512.

For example, for a normally closed switch, the movable contact 53 is located below the elastic section 512, and for a normally open switch, the movable contact 53 is located above the elastic section 512, and the above orientation of the movable contact 53 is arranged.

In some examples, by arranging the connection contact section 5132 in a horizontal direction such that the movable contact 53 is also arranged horizontally accordingly, when the stationary contact 60 in the switch is also arranged horizontally, the movable contact 53 and the stationary contact 60 can be brought into complete surface-to-surface contact, the contact area is increased, and a large contact pressure is obtained.

The elastic segments 512 may be in the shape of long strips with uniform width, or in the shape of long strips with non-uniform width. The length direction of the spring 51 refers to the distribution direction from the contact connecting section 513 to the terminal connecting section 511; the width direction of the spring piece 51 refers to a direction perpendicular to the longitudinal direction thereof and extending in a horizontal plane.

In some examples, the width of the resilient section 512 is not uniform, as shown in fig. 9, the resilient section 512 includes: the first elastic segment 5121 and the second elastic segment 5122 are connected, wherein one end of the first elastic segment 5121 far away from the second elastic segment 5122 is connected to the terminal connection segment 511, and one end of the second elastic segment 5122 far away from the first elastic segment 5121 is connected to the contact connection segment 513. From the terminal connection section 511 to the second elastic section 5122, the width of the first elastic section 5121 is gradually reduced, and the minimum width of the first elastic section 5121 is equal to the width of the second elastic section 5122.

By making the width of the first elastic segment 5121 longer at a position close to the terminal connection segment 511 and gradually smaller in a direction away from the terminal connection segment 511, it is possible to improve fatigue resistance between the elastic segment 512 and the terminal connection segment 511. This is because the position of the terminal connection section 511 is fixed, the elastic section 512 is frequently deformed and displaced with respect to the terminal connection section 511, and the unrecoverable hard deformation is prevented from occurring by increasing the width at the position to accommodate the frequent displacement of the elastic section 512. By making the width of the second elastic segment 5122 equal to the minimum width of the first elastic segment 5121, it is beneficial to increase the elastic deformability of the second elastic segment 5122, so that it has a higher deformation amount.

For the connection terminal 52, it is connected to the terminal connection segment 511 of the elastic sheet 51, and the connection mode between the two includes but is not limited to: welding, joint, riveting etc., wherein, modes such as joint, riveting are all dismantled easily, do benefit to the assembly process who simplifies binding post 52 and are convenient for maintain or change. For example, the connection terminal 52 is engaged with the terminal connection section 511.

For the movable contact 53, the structure of the movable contact 53 and the connection manner with the contact connection section 513 can all adopt the conventional technology in the art, and the embodiment of the present invention does not specifically limit this.

The switches related to the embodiment of the present invention are classified according to their control modes, and may be a single-gang single-control switch, or a single-gang double-control switch, wherein, when the switch is a single-gang single-control switch, the number of the movable contacts 53 in the movable contact assembly 5 is designed as one; when the switch is a single-gang double-control switch, the number of the movable contacts 53 in the movable contact assembly 5 is designed to be two symmetrically.

Transition piece 31 is attached to panel 1 in a manner including, but not limited to: clamping, riveting, welding, bonding, integrally forming connection and the like.

In some examples, the transition piece 31 is clamped to the panel 1, for example, the first side and the second side of the transition piece 31 opposite to each other are respectively provided with a clamping hole, and the bottom of the panel 1 is respectively provided with a buckle at a corresponding position, and the buckle is in fit clamping with the clamping hole, so that the transition piece 31 is connected to the panel 1. Wherein the distribution direction of the first and second sides of the transition piece 31 coincides with the distribution direction of the two pressing sides of the panel 1.

The transition piece 31 is further hinged to the base 2, for example, a pin is respectively connected to the middle of the third side and the fourth side of the transition piece 31, a bracket having a shaft hole is arranged at the corresponding position on the side of the base 2, and the pin is rotatably sleeved in the shaft hole, so that the transition piece 31 is hinged to the base 2. Wherein the distribution direction of the third and fourth sides of the transition piece 31 is perpendicular to the distribution direction of the first and second sides.

In order to make the function between the panel 1 and the transition piece 31 more stable and reliable, so that the panel 1 and the transition piece 31 can rotate synchronously, a plurality of joint bars can be arranged at the bottom of the panel 1 and inserted into the insertion holes arranged at the corresponding positions on the top of the transition piece 31.

The top end of the driving rib 300 is connected to one side of the bottom of the transition piece 31, and the bottom end of the driving rib 300 is used for abutting against the elastic sheet 51.
