Description

Rotary electric switch and switch layer thereof

Technical Field

The application relates to the field of switches, in particular to a rotary electrical switch for a photovoltaic system and a switch layer thereof.

Background

With the rapid development of the photovoltaic industry, the safety problem of the photovoltaic system is gradually concerned by the masses and becomes a hot spot problem in the industry in recent years. The photovoltaic direct current switch is applied to a photovoltaic system and used for controlling the electric connection between a photovoltaic cell panel and an inverter, so that the reliability of the photovoltaic direct current switch is related to the good operation of the whole photovoltaic system and the stable development of the photovoltaic industry. Photovoltaic dc switches face a core challenge: the unit breaking capacity is required to be larger and larger, but the size of a box body for accommodating the photovoltaic direct-current switch is required to be smaller and smaller. That is, the required unit breaking capacity and the compactness of the photovoltaic dc switch are a technical contradiction.

A commonly used photovoltaic dc switch is a rotary electrical switch, which typically comprises one or more modularly encapsulated contact modules, wherein the contact modules typically comprise a movable contact conductive assembly and a pair of stationary contact conductive elements, and a control module for controlling the one or more contact modules, the control module being operative to rotate the movable contact conductive assembly so that it can be switchably brought into and out of contact with the pair of stationary contact conductive elements to effect an electrical disconnection between the photovoltaic panel and the inverter.

In a dc return, when the voltage in the circuit is higher and higher or the current is higher and higher, the electrical disconnection will cause more electric arcs, and when the generated electric arcs exceed a certain limit, the photovoltaic dc switch will be burnt out or will not work normally. In the field of photovoltaic switches, the safe breaking capacity of a photovoltaic direct-current switch under preset voltage and current is measured by using a performance index of breaking capacity.

Some technical means for increasing the breaking capacity of the photovoltaic dc switch exist, such as increasing the rotation speed of the movable contact conductive assembly, adding a magnet to guide an arc, adding an arc chute, or increasing the diameter of the movable contact conductive element of the movable contact conductive assembly, but all of the above technical means increase the cost of the photovoltaic dc switch or increase the size of the photovoltaic dc switch.

Therefore, a new photovoltaic dc switch is desired, which can achieve compatibility between increase in breaking capacity and miniaturization without a large increase in cost.

Summary of the application

As mentioned above, electrical opens result in more arcing as the voltage in the circuit loop increases or the current increases. That is, as the voltage in the circuit loop increases or the current increases, the switching of the states of the switching layers of the rotary electrical switch generates more arcs, and the generated arcs exceed a certain limit, which may result in the switching layers being burned or failing to work properly.

The inventor of the application discovers through research on the existing rotary electric switch that: the existing rotary electric switch has important technical blind areas or technical prejudices.

Specifically, in the conventional rotary electrical switch such as that disclosed in patent publication No. CN 105742107a, a person skilled in the art appreciates that there is enough space between the stationary conductive elements between the upper and lower switch layers to satisfy the insulation requirement due to the requirement of high voltage insulation, and therefore, there is usually a relatively large "safety space" between the upper and lower switch layers in the conventional rotary electrical switch. However, this "safety space" is functionally redundant because the upper and lower switching layers have respective encapsulating housings, and therefore, when the upper and lower switching layers are assembled together, the upper and lower stationary conductive elements are insulated from each other by the presence of the encapsulating housings.

Based on the common consensus that the upper and lower layers of switch layers need to ensure high voltage insulation, the conventional rotary electrical switch usually arranges the movable contact conductive assembly and the stationary contact conductive element on the same plane. For example, in the rotary electrical switch disclosed in patent publication No. CN 105742107a, the housing of the switch layer of each rotary electrical switch has a central seat and a peripheral seat extending outward from the central seat, so that after the movable contact conductive member is mounted on the central seat and the stationary contact conductive member is mounted on the peripheral seat, the movable contact conductive member and the stationary contact conductive member are disposed in a plane (or the stationary contact conductive member is located outside the movable contact conductive member).

It will be appreciated by those skilled in the art that increasing the diameter of the movable contact conducting element of the movable contact conducting assembly is an important technical means to increase the breaking capacity of rotary electrical switches. However, the technical solution of increasing the diameter of the movable contact conducting element of the movable contact conducting assembly due to the existence of the technical dead zone (or technical prejudice) is hardly practicable in the actual industry, because once the diameter of the movable contact conducting element is increased, the size of the whole switch layer is inevitably increased due to the fact that each component in the switch layer is disposed in one plane, and the development trend of miniaturization of the switch layer is not met.

After discovering the above technical blind areas and technical biases, the present inventors have skillfully designed the extending manner of the stationary contact conductive members in each switch layer using the safety spaces between the stationary contact conductive members of two adjacent switch layers so that the movable contact conductive member and the stationary contact conductive member are at least partially overlapped in the axial direction along the rotary electric switch in a three-dimensional space, and in this way, it is possible to increase the diameter of the movable contact conductive member without increasing the size of the housing, that is, in a limited housing space. Accordingly, the increase in the diameter of the movable contact conductive member can increase the unit breaking capacity, and therefore, the rotary electric switch can achieve compatibility between the increase in the unit breaking capacity and miniaturization without a significant increase in cost, even without an increase in cost.

Based on this, the present application provides a switching layer comprising: the packaging shell forms a central bearing seat, wherein the central bearing seat is provided with a mounting cavity formed in the middle area of the central bearing seat and a pair of mounting channels formed in the edge area of the central bearing seat; a movable contact conductive assembly mounted within the mounting cavity, wherein the movable contact conductive assembly includes a movable contact conductive element; the pair of static contact conductive elements are respectively embedded in the pair of mounting channels; wherein the movable contact conductive element of the movable contact conductive assembly is adapted to be actuated to selectively engage or disengage a pair of the stationary contact conductive elements; wherein the movable contact conducting assembly and the pair of stationary contact conducting members are mounted on the central carrier in such a manner that at least one of the pair of stationary contact conducting members at least partially overlaps the plane of movement of the movable contact conducting member in the axial direction set by the switching layer.

In this regard, the present application also provides a rotary electrical switch comprising at least one switch layer as described above, and an actuation control element operatively connected to the at least one switch layer, wherein the actuation control element is configured to control the at least one switch layer to switch between a closed state and an open state.

Further, in the present embodiment, when the driving dial 121 is closed with the rotating base 123, the insertion head 12111 of the driving dial 121 is fittingly inserted into the central seat 123110 of the rotating base 123, the actuating element 1212 of the driving dial 121 corresponds to the supporting wall 12312, and the releasing element 1213 of the driving dial 121 corresponds to the at least one releasing arm 12313. More specifically, when the driving turntable 121 is covered with the rotating seat 123, the actuating element 1212 of the driving turntable 121 is located between the first end and the second end of the energy storage element 122, so that when the driving turntable 121 is rotated, the actuating element 1212 of the driving turntable 121 is adapted to drive the first end or the second end of the energy storage element 122 to rotate and the other end of the energy storage element 122 remains stationary to store energy in the energy storage element 122. It should be understood that when the driving dial 121 is rotated, the releasing member 1213 of the driving dial 121 can rotate along the at least one releasing arm 12313 until the locking head 12316 of the at least one releasing arm 12313 is released from the limiting arm 111 under the action of the releasing member 1213 to release the energy storage element 122. Accordingly, when the energy storage element 122 is in the energy release state, the energy storage element 122 that has stored energy can drive the rotation base 123 to rotate so as to drive the at least two switch layers to switch states.

From the perspective of the energy storage assembly 12, the rotating assembly 13 is configured to drive the energy storage assembly 12 to switch between an energy storage state and an energy release state, wherein when the energy storage assembly 12 is in the energy storage state, the locking head 12316 of the at least one release arm 12313 is in the locking state with the limiting arm 111, and the release member 1213 of the driving dial 121 rotates along the at least one release arm 12313 and acts downward on the at least one release arm 12313 under the action of the rotating assembly 13; when the energy storage assembly 12 is in the discharging state, the locking head 12316 of the at least one release arm 12313 is tripped between the limiting arm 111 under the action of the release element 1213 of the driving turntable 121, and the stored energy storage element 122 drives the rotation base 123 to rotate, thereby driving the switching between the states of the at least two switching layers.

As shown in fig. 4A to 4E, in the embodiment of the present application, the top surface of the at least one release arm 12313 is an arc surface, and more specifically, the top surface of the at least one release arm 12313 is an involute arc surface. It should be understood that when the release unit 1213 of the driving dial 121 rotates along the top surface of the at least one release arm 12313 under the action of the rotating assembly 13, due to the surface-type property of the top surface of the at least one release arm 12313, the downward force of the release unit 1213 on the at least one release arm 12313 will gradually increase with the increase of the rotation angle until the generated force can release the locking head 12316 of the at least one release arm 12313 from the limiting arm 111, that is, the energy storage assembly 12 completes the energy storage state and enters the energy release state.

Accordingly, in one specific example of the present application, the actuating element 1212 and the releasing element 1213 of the driving dial 121 are included at an angle ranging from 170 ° to 175 ° with respect to the set center, so that after the knob 13280 ° to 85 ° is rotated in a predetermined direction (e.g., clockwise or counterclockwise), the force applied by the releasing element 1213 of the driving dial 121 to the at least one releasing arm 12313 can release the at least one releasing arm 12313 from the limiting arm 111 to switch the state of the energy storage assembly 12. It should be understood that the trigger angle of 80 ° to 85 ° conforms to the operation habit of the user for the switch, and this trigger angle can avoid the misoperation to some extent.

It should be noted that, in the embodiment of the present application, the force applied by the release unit 1213 of the driving dial 121 on the at least one release arm 12313 depends not only on the surface-type characteristics of the top surface of the at least one release arm 12313, but also on the length between the locking head 12316 of the at least one release arm 12313 and the fixed end of the at least one release arm 12313. It should be noted that in some embodiments of the present application, the locking head 12316 of the at least one release arm 12313 is located at the free end of the at least one release arm 12313, such that the length dimension between the locking head 12316 of the at least one release arm 12313 and the fixed end of the at least one release arm 12313 is the length dimension between the free end of the at least one release arm 12313 and the fixed end thereof.

In particular, in the embodiment of the present application, the at least one release arm 12313 extends upward from the chassis 12311 and then extends along the circumference defined by the chassis 12311, such that the length dimension (i.e., moment arm length) between the free end and the fixed end of the at least one release arm 12313 can be increased without increasing the diameter of the at least one release arm 12313, thereby meeting the control requirement of the energy storage assembly 12 without increasing the radial dimension of the swivel base 123. Alternatively, in the present embodiment, the energy storage assembly 12 is reduced in size in the radial direction by sacrificing its dimension in the height direction.

For ease of illustration and understanding, in the present embodiment, the portion of the at least one release arm 12313 extending upwardly is defined as stiffener 123130 and the portion of the at least one release arm 12313 extending circumferentially of the chassis 12311 is defined as cantilevered portion 123131. It should be appreciated that in the present embodiment, the height dimension of the reinforcement 123130 (i.e., the height of the upwardly extending portion of the at least one release arm 12313) is dependent upon the control requirements of the energy storage assembly 12. Preferably, in the present embodiment, the width dimension of reinforcement portion 123130 of at least one release arm 12313 is greater than the width dimension of cantilever portion 123131 of at least one release arm 12313, and in this way, reinforcement portion 123130 can increase the strength reinforcement effect on at least one release arm 12313 with the same height dimension.

To facilitate operation and use of the rotary electrical switch, as shown in fig. 4A-4E, in some embodiments of the present application, the at least one release arm 12313 includes a first release arm 12314 extending from the chassis 12311 first upwards and then along the circumference of the chassis 12311 and a second release arm 12315 extending from the chassis 12311 first upwards and then along the circumference of the chassis 12311, wherein the first release arm 12314 extends along the circumference of the chassis 12311 in a direction opposite to the second release arm 12315 along the circumference of the chassis 12311, e.g., the first release arm 12314 extends in a counterclockwise direction along the circumference of the chassis 12311 and the second release arm 12315 extends along the circumference of the chassis 12311 in a clockwise direction, e.g., the first release arm 12314 extends along the circumference of the chassis 12311 in a clockwise direction and the second release arm 12315 extends along the circumference of the chassis 12311 Extending in a counterclockwise direction, by which the state switching of the energy storage assembly 12 can be achieved regardless of whether the knob 132 of the rotating assembly 13 is rotated in a clockwise direction or a counterclockwise direction, the operation and use of the rotary electric switch can be greatly improved.

As shown in fig. 4A to 4E, the first release arm 12314, the second release arm 12315 and the support wall 12312 approximately enclose a circumference with each other, and a housing channel 12310 for housing the energy storage element 122 is set between the center seat 123110 of the swivel base 123 and the circumference enclosed by the support wall 12312, the first release arm 12314 and the second release arm 12315.

Preferably, in the present embodiment, the first release arm 12314 and the second release arm 12315 are symmetrically arranged with respect to the central axis defined by the chassis 12311, such that the user can switch the state of the energy storage assembly 12 by rotating clockwise or counterclockwise by a nearly uniform angle.

More preferably, in the present embodiment, the reinforcement portion 123130 of the first release arm 12314 and the reinforcement portion 123130 of the second release arm 12315 are at least partially overlapped (or, the reinforcement portion 123130 of the first release arm 12314 and the reinforcement portion 123130 of the second release arm 12315 are connected to each other), so that the reinforcement portion 123130 of the first release arm 12314 can reinforce not only the first release arm 12314 but also the second release arm 12315; similarly, the reinforcement 123130 of the second release arm 12315 can reinforce not only the second release arm 12315 but also the first release arm 12314, in such a way that the diameter of the first release arm 12314 and the second release arm 12315 can be further reduced so as to reduce the radial dimension of the energy storage assembly 12 and the radial dimension of the whole rotary electrical switch, thereby meeting the trend of the rotary electrical switch to save energy.

More preferably, in the present embodiment, the first release arm 12314 and the second release arm 12315 share one reinforcement portion 123130, i.e., the reinforcement portion 123130 of the first release arm 12314 and the reinforcement portion 123130 of the second release arm 12315 are completely overlapped, in such a way that not only the structural design of the swivel base 123 can be simplified to facilitate industrial production, but also the dimensional design of the first release arm 12314 and the second release arm 12315 can be optimized to the greatest extent.

Of course, in other embodiments of the present application, the first release arm 12314 and the second release arm 12315 are two completely independent release arms, as shown in fig. 4F. That is, in this embodiment, the reinforcement portion 123130 of the first release arm 12314 and the reinforcement portion 123130 of the second release arm 12315 are not connected to each other, and this is not intended to limit the present application.

It should be understood that in the present embodiment, the rotating assembly 13 and the energy storage assembly 12 cooperate with each other for the purpose of controlling the switching of the states of the at least two switching layers. Here, for convenience of explanation and understanding, it is exemplified that the at least two switching layers include two switching layers (a first switching layer 21 and a second switching layer 22) as shown in fig. 2. It should be understood, however, that in other examples of the present application, the rotary electrical switch may include a greater number of switching layers (as shown in fig. 10), and is not intended to be limited thereto.

As shown in fig. 3A and 3B, in some embodiments of the present application, the first switching layer 21 and the second switching layer 22 are assembled together to form the multi-layer switching layer structure 20, wherein the second switching layer 22 is located at a lower side of the first switching layer 21, and the first switching layer 21 is located at an upper side of the second switching layer 22. Accordingly, in the embodiment of the present application, each of the switch layers includes an encapsulating housing, a movable contact conductive assembly mounted on the encapsulating housing, and a pair of stationary contact conductive elements mounted on the encapsulating housing, wherein the movable contact conductive assembly is adapted to be switchably conducted or disconnected with the pair of stationary contact conductive elements under the action of the rotating assembly 13 and the energy storage assembly 12 to realize the switching of the states of the switch layers.

Specifically, the first switch layer 21 on the top side includes a first package housing 211, a first movable contact conductive assembly 212 mounted on the first package housing 211, and a pair of first stationary contact conductive elements 213 mounted on the first package housing 211, wherein the first movable contact conductive assembly 212 is drivingly connected to the connection head 1232 of the energy storage assembly 12, so that under the control of the rotating assembly 13 and the energy storage assembly 12, the first movable contact conductive assembly 212 can selectively engage with or disengage from the pair of first stationary contact conductive elements 213 to realize the state switching (on/off) of the first switch layer 21. The second switch layer 22 at the bottom side includes a second package housing 221, a second movable contact conductive assembly 222 mounted on the second package housing 221, and a pair of second static contact conductive elements 223 mounted on the second package housing 221, wherein the second movable contact conductive assembly 222 is drivingly connected to the first movable contact conductive assembly 212 of the first switch layer 21, so that when the first movable contact conductive assembly 212 is driven under the action of the rotating assembly 13 and the energy storage assembly 12, the second movable contact conductive assembly 222 is driven to selectively engage with or disengage from the pair of second static contact conductive elements 223 to realize the state switching (on/off) of the second switch layer 22.

More specifically, as shown in fig. 3A, the first package housing 211 forms a first center carrier 2111, the first center carrier 2111 having a first mounting cavity 2112, wherein the first movable contact conductive assembly 212 is fittingly fitted into the first mounting cavity 2112 of the first center carrier 2111. Accordingly, the first movable contact conductive assembly 212 includes a first insulating disk 2121, a first dial element 2122 for driving the first insulating disk 2121, and a first movable contact conductive element 2123 insulatedly sandwiched between the first insulating disk 2121 and the first dial element 2122.

More specifically, in the embodiment of the present application, the first movable contact conducting member 2123 is fittingly provided to the first insulating disk 2121 along a center line of the first insulating disk 2121, and a diameter of the first movable contact conducting member 2123 is similar to a diameter of the first insulating disk 2121, so that an edge of the first movable contact conducting member 2123 is approximately flush with an edge of the first insulating disk 2121 after the first movable contact conducting member 2123 is mounted to the first insulating disk 2121. Accordingly, the first movable contact conducting member 2123 has a first movable contact conducting end 2124 formed at a first end portion thereof and a second movable contact conducting end 2125 formed at a second end portion thereof (opposite to the first end portion), that is, in the embodiment of the present application, the first movable contact conducting end 2124 of the first movable contact conducting member 2123 is formed at an edge of the first insulating rotary disk 2121, and the second movable contact conducting end 2125 of the first movable contact conducting member 2123 is formed at an edge of the first insulating rotary disk 2121.

Accordingly, in the present embodiment, the first dial element 2122 is engaged with the connecting head 1232 of the energy storage assembly 12, and in this way, the first movable contact conductive assembly 212 is drivingly connected to the energy storage assembly 12, such that under the action of the rotating assembly 13 and the energy storage assembly 12, the first dial element 2122 is rotated to rotate the first insulating dial 2121 on which the first movable contact conductive element 2123 is mounted. Further, in the embodiment of the present application, a pair of the first stationary contact conductive elements 213 are mounted on the first central bearing seat 2111, the first stationary contact conductive elements 213 respectively have first stationary contact conductive ends 2131, wherein the pair of the first stationary contact conductive elements 213 are mounted on the first central bearing seat 2111 in such a position that the first stationary contact conductive ends 2131 of the pair of the first stationary contact conductive elements 213 are located on the central axis of the first central bearing seat 2111 and adjacent to the edge of the first insulating turntable 2121, and by such a position and structure configuration, the first movable contact conductive end 2124 and the second movable contact end 2125 of the first movable contact conductive element 2123 of the first movable contact conductive assembly 212 can be simultaneously combined with or separated from the first stationary contact conductive ends 2131 of the pair of the first stationary contact conductive elements 213 under the action of the rotating assembly 13 and the energy storage assembly 12, to enable state switching of the first switching layer 21.

More specifically, as shown in fig. 3B and 5, the second package housing 221 forms a second central bearing seat 2211, the second central bearing seat 2211 has a second mounting cavity 2212, and the second movable contact conductive assembly 222 is fittingly fitted into the second mounting cavity 2212 of the second central bearing seat 2211. Accordingly, the second movable contact conductive assembly 222 includes a second insulating turntable 2221, a second dial element 2222 for driving the second insulating turntable 2221, and a second movable contact conductive element 2223 which is insulatively clamped between the second insulating turntable 2221 and the second dial element 2222. More specifically, in the embodiment of the present application, the second movable contact conductive member 2223 is fittingly disposed to the second insulating rotary table 2221 along the central axis of the second insulating rotary table 2221, and the diameter of the second movable contact conductive member 2223 is similar to the diameter of the second insulating rotary table 2221, so that the edge of the second movable contact conductive member 2223 is approximately flush with the edge of the second insulating rotary table 2221 after the second movable contact conductive member 2223 is mounted to the second insulating rotary table 2221. Accordingly, the second movable contact conductive member 2223 has a third movable contact conductive end 2224 formed at a first end portion thereof and a fourth movable contact conductive end 2225 formed at a second end portion thereof (opposite to the first end portion), that is, in the embodiment of the present application, the third movable contact conductive end 2224 of the second movable contact conductive member 2223 is formed at the edge of the second insulating rotary table 2221, and the fourth movable contact conductive end 2225 of the second movable contact conductive member 2223 is formed at the edge of the second insulating rotary table 2221.

Accordingly, in the present embodiment, the second dial plate 2222 is engaged with the first insulating turntable 2121, and in this way, the second movable contact conductive assembly 222 is drivingly connected to the first movable contact conductive assembly 212, so that when the first movable contact conductive assembly 212 rotates under the action of the rotating assembly 13 and the energy storage assembly 12, the second dial plate 2222 is rotated to rotate the second insulating turntable 2221 on which the second movable contact conductive member 2223 is mounted. Further, in the present embodiment, a pair of the second fixed contact conducting elements 223 are mounted on the second central carrier 2211, the second fixed contact conducting elements 223 respectively have second fixed contact conducting ends 2231, wherein a pair of the second fixed contact conducting elements 223 are mounted on the second central carrier 2211 at a position such that the second fixed contact conducting ends 2231 of the pair of the second fixed contact conducting elements 223 are located on the central axis of the second central carrier 2211 and adjacent to the edge of the second insulating rotary table 2221, by such a position and structure configuration that the third movable contact conducting end 2224 and the fourth movable contact conducting end 2225 of the second movable contact conducting element 2223 of the second movable contact conducting assembly 222 can be simultaneously combined with or separated from the second fixed contact conducting ends 2231 of the pair of the second fixed contact conducting elements 223 under the action of the rotating assembly 13 and the energy storage assembly 12, to effect state switching of the second switching layer 22.

As mentioned before, electrical disconnection leads to more arcing when the voltage in the circuit loop, which is participated by the rotary electrical switch, is higher and higher or the current is higher and higher. That is, when the voltage in the circuit loop is higher and higher or the current is higher and higher, the switching of the states of the first switching layer 21 and the second switching layer 22 may generate more arcs, and when the generated arcs exceed a certain limit, the first switching layer 21 and/or the second switching layer 22 may be burnt or may not work properly.

The inventor of the application discovers through research on the existing rotary electric switch that: an important technical blind area or technical prejudice exists in the existing rotary electric switch. First, in the conventional rotary electrical switch such as that disclosed in patent publication No. CN 105742107a, a person skilled in the art appreciates that there is enough space between the static contact conductive elements between the upper and lower switch layers to satisfy the insulation requirement due to the requirement of high voltage insulation, and therefore, there is usually a relatively large "safety space" between the upper and lower switch layers in the conventional rotary electrical switch. However, this "safety space" is functionally redundant because the upper and lower switching layers have respective enclosure housings, and thus, when the upper and lower switching layers are assembled together, the stationary conductive elements of the upper and lower layers are insulated from each other by the enclosure housings. Also, the conventional rotary electrical switch has the movable contact conductive member and the stationary contact conductive member arranged on the same plane. For example, in the rotary electric switch disclosed in patent publication No. CN 105742107a, the housing of the switch layer has a central seat 123110 and a peripheral seat located outside the central seat 123110, so that after the movable contact conductive member is mounted on the central seat 123110 and the stationary contact conductive member is mounted on the peripheral seat, the movable contact conductive member and the stationary contact conductive member are disposed in a plane (or the stationary contact conductive member is located outside the movable contact conductive member).

After discovering the technical dead zone and the technical bias, the inventor of the application skillfully designs the extending mode of the static contact conducting elements in each switch layer by utilizing the safety space between the static contact conducting elements of two adjacent switch layers so that the movable contact conducting elements and the static contact conducting elements are at least partially overlapped along the axial direction of the rotary electric switch in a three-dimensional space, and by the mode, the whole size of the rotary electric switch can not be increased under the condition of increasing the diameter of the movable contact conducting elements. Accordingly, the increase in the diameter of the movable contact conductive member can increase the unit breaking capacity, and therefore, the rotary electric switch can achieve compatibility between the increase in the unit breaking capacity and miniaturization without a large increase in cost.

Specifically, as shown in fig. 3A, in the embodiment of the present application, the first central bearing seat 2111 of the first package housing 211 has a first mounting channel 2113 and a second mounting channel 2114 concavely formed at edge regions thereof, wherein a pair of the first static contact conductive elements 213 are fittingly mounted in the first mounting channel 2113 and the second mounting channel 2114, respectively. In particular, in the present embodiment, the first and second mounting passages 2113 and 2114 are formed at the formation position and extension of the first central bearing seat 2111 and the shape configuration of the pair of first fixed contact conductive elements 213 are such that at least one first fixed contact conductive element 213 of the pair of first fixed contact conductive elements 213 and the first movable contact conductive element 2123 at least partially overlap in the axial direction set by the first switch layer 21 after the pair of first fixed contact conductive elements 213 are mounted to the first and second mounting passages 2113 and 2114, respectively, in such a manner that the first fixed contact conductive element 213 and the first movable contact conductive element 2123 are folded in the three-dimensional space set by the first enclosing housing 211, thereby making it possible to increase the diameter of the first movable contact conductive element 2123 to increase the breaking capacity of the first switch layer 21 The dimensions of the first switching layer 21 are maintained.

Similarly, as shown in fig. 3B, in the embodiment of the present application, the second central bearing seat 2211 of the second package body 221 has a third mounting passage 2213 and a fourth mounting passage 2214 concavely formed at edge regions thereof, wherein a pair of the second static contact conductive elements 223 are respectively fittingly mounted in the third mounting passage 2213 and the fourth mounting passage 2214. In particular, in the present embodiment, the third and fourth mounting passages 2213 and 2214 are configured in the forming position and shape of the second central bearing seat 2211 and the shape of the pair of the second stationary contact conductive members 223 are configured such that at least one second stationary contact conductive member 223 of the pair of the second stationary contact conductive members 223 is at least partially overlapped with the second movable contact conductive member 2223 in the axial direction set by the second switch layer 22 after the pair of the second stationary contact conductive members 223 are mounted to the third and fourth mounting passages 2213 and 2214, respectively, in such a manner that the second stationary contact conductive member 223 and the second movable contact conductive member 2223 are folded in the three-dimensional space set by the second package body 221, thereby enabling to increase the diameter of the second movable contact conductive member 2223 to increase the breaking capacity of the second switch layer 22 While still maintaining the dimensions of the second switching layer 22.

For convenience of description, the relative positional relationship between the movable contact conductive element and the stationary contact conductive element will be described by taking the second switch layer 22 as an example.

As shown in fig. 5 and 6, in the present embodiment, the third and fourth mounting passages 2213 and 2214 are formed in two opposite side regions of the second central bearing seat 2211, respectively, for example, in some embodiments, the third and fourth mounting passages 2213 and 2214 are concavely formed in two opposite side regions of the second central bearing seat 2211, respectively. Accordingly, the third and fourth mounting passages 2213 and 2214 respectively communicate with the second mounting cavity 2212 of the second central bearing seat 2211, wherein after the pair of second stationary contact conductive elements 223 are respectively mounted in the third and fourth mounting passages 2213 and 2214, the second stationary contact conductive ends 2231 of the pair of second stationary contact conductive elements 223 are adjacent to or at the edge of the second insulating disk 2221 at the mounting position of the second central bearing seat 2211.

In the embodiment of the present application, the second movable contact conductive member 2223 and the second fixed contact conductive ends 2231 of the pair of second fixed contact conductive members 223 are disposed in a coplanar manner in the three-dimensional space defined by the second enclosing shell 221, as shown in fig. 6. For convenience of illustration, the internal three-dimensional space defined by the second housing 221 is divided into an upper space 2215 and a lower space 2216 by using a plane defined by the second movable contact conductive member 2223 and the second fixed contact conductive ends of the pair of second fixed contact conductive members 223 as a boundary, wherein the plane defined by the second movable contact conductive member 2223 and the second fixed contact conductive ends 2231 of the pair of second fixed contact conductive members 223 belongs to the upper space 2215, as shown in fig. 6.

In particular, in the present embodiment, the third and/or fourth mounting passages 2213 and 2214 extend from the upper space 2215 of the second package housing 221 to the lower space 2216 thereof, and by such a shape configuration, after a pair of the second stationary contact conductive elements 223 are mounted to the third and fourth mounting passages 2213 and 2214, at least one second stationary contact conductive element 223 of the pair of the second stationary contact conductive elements 223 extends from the upper space 2215 of the second package housing 221 to the lower space 2216 thereof. That is, in the embodiment of the present application, at least one second static conductive element 223 of the pair of second static conductive elements 223 extends in a bending manner in the three-dimensional space defined by the second package housing 221, such that at least one second stationary contact conductive member 223 of a pair of the second stationary contact conductive members 223 at least partially overlaps the second movable contact conductive member 2223 in the axial direction set by the second switch layer 22 (as shown in figure 7B), in this way, the second stationary contact conductive member 223 and the second movable contact conductive member 2223 are folded in the three-dimensional space defined by the second housing 221, so that the size of the second switch layer 22 can be maintained while increasing the diameter of the second movable contact conductive element 2223 to increase the breaking capacity of the second switch layer 22.

As seen from the relative position relationship between the second mounting cavity 2212 of the second central bearing seat 2211 and the third mounting passage 2213, and the relative position relationship between the second mounting cavity 2212 of the second central bearing seat 2211 and the fourth mounting passage 2214, in the present embodiment, the second mounting cavity 2212 of the second central bearing seat 2211 and the third mounting passage 2213 and/or the fourth mounting passage 2214 at least partially overlap in the axial direction set by the second switch layer 22, so that the second movable contact conductive element 2223 and at least one of the pair of second stationary contact conductive elements 223 are folded and arranged in the three-dimensional space set by the second package housing 221, thereby being capable of maintaining the size of the second switch layer 22 while increasing the diameter of the second movable contact conductive element 2223 to increase the breaking capacity of the second switch layer 22.

Further, in the present embodiment, a pair of the second stationary contact conductive elements 223 are respectively fitted into the third and fourth mounting passages 2213 and 2214 from the side of the second central bearing seat 2211.
