Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. It should be noted that, under the condition of no conflict, the features of the embodiments of the present utility model may be combined with each other, and the combined embodiments still fall within the protection scope of the present utility model.

Furthermore, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.
In the description of the present utility model, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
In an aspect of the embodiment of the present utility model, as shown in fig. 3, an isolating switch is provided, which includes an operating mechanism 100 and a switch body 200, wherein the switch body 200 can be connected to a load circuit, and the operating mechanism 100 and the switch body 200 can be driven in a matched manner, so that under the action of the operating mechanism 100, the switch body 200 can be driven to perform switching-on or switching-off, and switching-on or switching-off of the load circuit is correspondingly implemented according to requirements. In practical arrangement, the switch body 200 may be fixedly disposed on the side of the housing 110 where the operating mechanism 100 is located, and the fixing manner may be detachable connection or non-detachable connection, for example, the detachable connection may be a plurality of manners such as screwing, clamping, splicing, etc.
As shown in fig. 3 and fig. 9 to fig. 11, the operating mechanism 100 may rotationally drive the contact system in the switch body 200 to perform switching on or off in a rotational manner, and the extending direction b of the rotating shaft of the operating mechanism 100 and the extending direction c of the rotating shaft of the switch body 200 may not overlap (e.g. be parallel or intersect), so that the rotating shaft of the operating mechanism 100 and the rotating shaft of the switch body 200 may be prevented from forming a straight coaxial structure, and thus the isolating switch may have multiple forms, and the limitations imposed during installation and use of the isolating switch are reduced. For example, as shown in fig. 3 and 9 to 11, the extending direction b of the rotation axis of the operating mechanism 100 is parallel to the extending direction c of the rotation axis of the switch body 200; for another example, the extending direction of the rotation axis of the operating mechanism 100 intersects with the extending direction of the rotation axis of the switch body 200, so that the isolating switch can avoid being limited by the in-line coaxial structure, and thus, the requirement of various installation and use environments can be met in various new layout modes.
On this basis, when the extending direction of the rotation axis of the operating mechanism 100 intersects with the extending direction of the rotation axis of the switch body 200, further, the extending direction of the rotation axis of the operating mechanism 100 and the extending direction of the rotation axis of the switch body 200 are mutually perpendicular.
It should be understood that vertical or parallel in the present utility model does not refer to absolute vertical or absolute parallel, but may be approximately vertical or approximately parallel. In addition, the on-off state in the utility model comprises different states such as on-off state and off-off state.
Optionally, the switch body 200 includes at least one switch assembly 210, the switch assembly 210 includes at least one switch unit 220, and specifically, referring to fig. 1, the switch body 200 may be composed of at least one switch assembly 210, and the number of switch assemblies 210 may be at least one. The switch assembly 210 includes at least one switch unit 220, each switch unit 220 includes a contact system, the contact system includes a fixed contact 225 and a moving contact 222 that are matched to each other to be opened and closed, the moving contact 222 has a rotation axis 224, and for the same switch assembly 210, the at least one switch unit 220 included therein may be arranged in a stacked manner along an extending direction (i.e., a first direction a) of the rotation axis of the switch assembly 210, thereby facilitating coaxial rotation axes 224 of the moving contacts 222 in the respective switch units 220 in the same switch assembly 210 (e.g., coaxial rotation axes 224 of the moving contacts 222 in the two switch units 220 in the switch assembly 210 shown in fig. 1) as the rotation axis of the switch assembly 210. Of course, when the switch body 200 has one switch assembly 210, the rotation axis of the switch assembly 210 is the rotation axis of the switch body 200 (for example, as shown in fig. 1, or a plurality of switch units 220 shown in fig. 11 are stacked in the same direction and divided into one switch assembly 210); however, when the switch body 200 has a plurality of switch assemblies 210, in order to facilitate that the plurality of switch assemblies 210 can form a good driving connection with the operating mechanism 100, the rotation axes of the plurality of switch assemblies 210 can be all in the same direction (for example, parallel as shown in fig. 2, 3, 9 or 10, or overlap as shown when the plurality of switch units 220 shown in fig. 11 are all stacked in the same direction and divided into two or more switch assemblies 210), and thus, the rotation axis of any one switch assembly 210 can be used as the rotation axis of the switch body 200.
With the vigorous development of the photovoltaic industry, the demand for the intellectualization of photovoltaic inverters is increasing. When a photovoltaic circuit breaks down, the isolating switch, which is a key component of the breaking function, must divide the circuit in the shortest time to protect other components, so that the isolating switch has good breaking performance and has important significance for the load circuit to which the isolating switch is connected.
Therefore, in some embodiments, the switch body 200 may adopt a rectangular layout, that is, as shown in fig. 2 to 6, 9 or 10, the switch body 200 includes two or more switch assemblies 210, the extending direction of the rotation axis of each switch assembly 210 is a first direction a, at least two switch assemblies 210 are stacked along a second direction B, and the first direction a and the second direction B are mutually perpendicular in space, so that the number of switch units stacked on the same rotation axis can be reduced on the basis of arranging the same number of switch units 220 by using the rectangular layout, so that the problem of poor transmission consistency caused by assembly gaps when the number of switch units stacked is large can be alleviated, and the isolating switch has better breaking consistency.
As shown in fig. 1 to 3, 6, 9 or 10, when the rotation axis of the switch body 200 or the rotation axis of the switch assembly 210 extends in the first direction a, the operating mechanism 100 and the switch body 200 may be arranged in the second direction B, so that the arrangement direction of the operating mechanism 100 and the switch body 200 is perpendicular to the extending direction of the rotation axis of the switch body 200, and the rotation axis 224 of the moving contact 222 extends in the first direction a perpendicular to the second direction B, so that the operating mechanism 100 and each switch assembly 210 are conveniently connected in a driving manner.
The number of the switch assemblies 210 in the switch body 200 may be at least one, specifically: for example, as shown in fig. 1, an isolating switch is provided, where the switch body 200 includes a switch assembly 210 stacked with the operating mechanism 100 along the second direction B, and a moving contact 222 of a switch unit 220 in the switch assembly 210 and the operating mechanism 100 establish driving, so that under the action of the operating mechanism 100, the switch assembly 210 can be driven to realize switching on and off; as shown in fig. 2, for example, there is provided an isolating switch, wherein the switch body 200 includes an operating mechanism 100 and two switch assemblies 210 that are stacked and arranged along a second direction B, and the operating mechanism 100 is respectively in driving connection with moving contacts 222 of switch units 220 in the two switch assemblies 210, so that under the action of the operating mechanism 100, the two switch assemblies 210 can be driven to be synchronously opened and closed; as shown in fig. 3 and fig. 4, for example, there is provided an isolating switch, wherein the switch body 200 includes an operating mechanism 100 and three switch assemblies 210 stacked in a second direction B, and the operating mechanism 100 is respectively in driving connection with moving contacts 222 of switch units 220 in the three switch assemblies 210, so that under the action of the operating mechanism 100, the three switch assemblies 210 can be driven to be synchronously opened and closed.
The number of the switch units 220 in the switch assembly 210 may be at least one, specifically: for example, as shown in fig. 2, there is provided an isolating switch, wherein for the same switch assembly 210, the isolating switch comprises a switch unit 220 arranged along a first direction a, and the operating mechanism 100 is in driving connection with a moving contact 222 of one switch unit 220 in the switch assembly 210, so that under the action of the operating mechanism 100, the switch unit 220 in the switch assembly 210 can be driven to be closed and opened; as shown in fig. 1, for example, an isolating switch is provided, where for the same switch assembly 210, the isolating switch includes two switch units 220 stacked and arranged along a first direction a, each switch unit 220 can be connected to a circuit, and the operating mechanism 100 is respectively connected with the moving contacts 222 of the two switch units 220 in the switch assembly 210 in a driving manner, so that under the action of the operating mechanism 100, the two switch units 220 in the switch assembly 210 can be driven to be synchronously switched on and off; as shown in fig. 3 and fig. 4, for example, an isolating switch is provided, where for the same switch assembly 210, the isolating switch includes four switch units 220 stacked along the first direction a, each switch unit 220 may be connected to a circuit, and the operating mechanism 100 is respectively connected to the moving contacts 222 of the four switch units 220 in the switch assembly 210 in a driving manner, so that under the action of the operating mechanism 100, the four switch units 220 in the switch assembly 210 can be driven to be synchronously opened and closed.
In order to simplify the transmission structure and ensure better switching uniformity, when the switch assembly 210 includes a plurality of switch units 220 stacked and arranged along the first direction a (for example, fig. 1, fig. 4, fig. 9 or fig. 10), the rotating shafts 224 of the moving contacts 222 of at least two switch units 220 in the same switch assembly 210 can be coaxially and nestedly transmitted along the first direction a, so that the operating mechanism 100 can only drive the nearest switch unit 220, and can drive the rest switch units 220 to synchronously switch and switch by means of the coaxial nesting. The rotating shafts 224 of the two coaxially nested switch units 220 in the same switch assembly 210 can establish a driving relationship for rotating around a shaft in a manner of inserting the prism holes into the prism ends, for example, the rotating shaft 224 of the moving contact 222 is a square shaft, one end of the square shaft is provided with a square hole, and the other end of the square shaft is provided with a square shaft, so that the rotating shafts 224 of the moving contacts 222 in two adjacent switch units 220 can be driven around a shaft in a manner of inserting the square shaft into the square hole.
The contact system built in the switch unit 220 in the utility model can only comprise a group of mutually matched movable and fixed contacts 225 (each group only comprises a fixed contact 225 and a movable contact 222), and can also comprise two groups, three groups or multiple groups of mutually matched movable and fixed contacts 225, according to the difference of the number of the groups, the corresponding circuit can form a single break point, a double break point, a triple break point or multiple break points when the connected circuit is disconnected, the utility model does not limit the circuit, and the utility model can be correspondingly arranged according to the actually applicable scene of the switch body 200 so as to meet different performance requirements. It should be noted that, when the moving contacts 225 that are matched with each other are divided in the above-mentioned group manner, only the division is performed from the matching relationship, and the mutual separation of the actual structures is not represented, for example, as shown in fig. 5 and 7, two moving contacts 222 in two groups of moving contacts 225 may be integrated in the same moving contact support 223 to form a structural member, two end portions of the middle structural member may be respectively used as two moving contacts 222, one of the two moving contacts is matched with the upper side fixed contact 225, and the other moving contact is matched with the lower side fixed contact 225, thereby forming a double-break structure, and the middle shaft of the structural member is used as the rotating shaft 224 of the moving contact 222 in the switch unit 220 to be matched and driven with the operating mechanism 100.
Referring to fig. 5, the switch unit 220 in the present utility model may include a unit housing 221, a contact system and arc extinguishing chambers 226, where the contact system and the arc extinguishing chambers 226 are distributed in the unit housing 221, and the number of the arc extinguishing chambers 226 may be correspondingly matched according to the number of breakpoints of the contact system, for example, in fig. 5, the contact system includes two sets of moving contacts 225 matched with each other, so that the two arc extinguishing chambers 226 may be respectively matched with the areas of the two sets of moving contacts 225 where arcs are generated, thereby improving the arc extinguishing capability.
When the operation mechanism 100 is in driving connection with the moving contacts 222 in the switch unit 220, as shown in fig. 4 to 7, the isolating switch further comprises a transmission member 330, and the transmission member 330 extends along the second direction B, so that the operation mechanism 100 is conveniently in driving connection with the switch assemblies 210 which are arranged in a stacked manner along the second direction B through the transmission member 330, and in particular, the transmission member 330 extends along the second direction B and is sequentially in driving connection with the rotating shafts of the switch assemblies 210, so that the operation mechanism 100 can synchronously switch on and switch off all the switch assemblies 210 through the transmission member 330, and the isolating switch has better breaking consistency and effectively improves the breaking performance of the isolating switch.
In some embodiments, when the switch body 200 includes a plurality of switch assemblies 210, the plurality of switch assemblies 210 may be distributed on the same side of the transmission 330.
In some embodiments, when the switch body 200 includes a plurality of switch assemblies 210, the plurality of switch assemblies 210 may be distributed on opposite sides of the transmission member 330, and in particular, may be uniformly distributed or non-uniformly distributed.
Correspondingly, when the switch body 200 includes a plurality of switch assemblies 210 and the switch assemblies 210 are distributed on the same side or opposite sides of the transmission member 330, the switch units 220 included in each switch assembly 210 are distributed on the same side of the transmission member 330.
Of course, in still other embodiments, as shown in fig. 4, the transmission member 330 may be penetrated by the inside of the switch assembly 210, that is, the switch units 220 in the switch assembly 210 are distributed on opposite sides of the transmission member 330, thereby effectively balancing the forces on opposite sides of the transmission member 330, so that the transmission of the transmission member 330 is smoother.
In order to further improve the stability of the transmission, the switch assemblies 210 include a plurality of switch units 220 symmetrically distributed on opposite sides of the transmission member 330, in other words, the switch units 220 in the same switch assembly 210 are distributed on opposite sides of the transmission member 330 in equal numbers, for example, as shown in fig. 4, the switch body 200 includes three switch assemblies 210 stacked along the second direction B, each switch assembly 210 includes four switch units 220 stacked along the first direction a, two of the four switch units 220 are located on the upper side of the transmission member 330, and the other two switch units are located on the lower side of the transmission member 330, so that when the transmission member 330 distributed in the middle drives the moving contacts 222 of the switch units 220 in the switch assemblies 210 to move, the switch assemblies have better balance, and are beneficial to improving the consistency of the closing and opening of the isolating switch.
In some embodiments, the transmission member 330 includes a plurality of translation portions and rotation portions 333 connected to each other, the rotation portions 333 may be three, for example, fig. 6 and 7, the three rotation portions 333 are respectively connected to the rotation shafts 224 of the three switch assemblies 210, one end of the translation portion is connected to the operating mechanism 100, and the translation portion extends along the second direction B, so that the translation portion is conveniently connected to the plurality of rotation portions 333 arranged along the second direction B in sequence, and thus the operating mechanism 100 can be formed to be connected to the rotation shaft of the switch assembly 210 sequentially through the translation portion and the rotation portions 333 in a driving manner.
In actual driving, the operating mechanism 100 may drive the translation portion to translate, so as to generate a displacement component along the second direction B, thereby enabling the translation portion to drive the rotation shaft of the switch assembly 210 to rotate through the rotation portion 333, so as to achieve the purpose of opening and closing the movable contact 222 with the fixed contact 225 through rotation.
In some embodiments, as shown in fig. 6 and 7, the translation portion is a connecting rod 331, one end of the connecting rod 331 is connected to the operating mechanism 100, the connecting rod 331 is hinged to the rotation portion 333 in sequence by using its own extension length along the second direction B, and the rotation portion 333 may be sleeved on the rotation shaft 224 of the moving contact 222 in a shaft hole matching manner, so when the operating mechanism 100 drives the connecting rod 331 to generate a displacement component along the second direction B, the moving contact 222 can be driven to rotate around the rotation shaft 224 by the rotation portion 333.
In some embodiments, as shown in fig. 6, a waist-shaped hole 332 is provided at an end of the connecting rod 331, and the driving end 130 of the operating mechanism 100 is slidably connected to the waist-shaped hole 332, so that interference that may occur among the operating mechanism 100, the driving member 330 and the rotating shaft 224 of the moving contact 222 can be effectively balanced by using the waist-shaped hole 332, and smoothness and stability of transmission are improved.
In some embodiments, the translation portion may be a rack, the rotation portion 333 may be a gear meshed with the rack, the operating mechanism 100 is in driving connection with the rack, and the gear is fixedly disposed with the rotating shaft 224 of the moving contact 222, so that when the gear is meshed with the rack, the operating mechanism 100 can be utilized to drive the rack to displace, and further drive the gear and the rotating shaft 224 to rotate synchronously, thereby realizing the turning on/off of the moving contact 222.
In order to improve the operability of the isolating switch, as shown in fig. 3 to 11, the isolating switch may further include a handle 310, the handle 310 is in driving connection with the operating mechanism 100, and an operating end of the handle 310 extends out of the housing 110 accommodating the operating mechanism 100, so as to be convenient for a user to use. When the handle 310 is set, the handle 310 and the operating mechanism 100 can be arranged along the first direction A or the second direction B, so that different operation modes of normal operation or side operation are formed, and when the handle 310 is actually set, the handle can be adaptively and selectively adjusted according to the actual installation and use environments, so that the installation and use of different environments are met.
Specifically, for example, fig. 3, 6 and 9 show: the handle 310, the operating mechanism 100 and the switch body 200 are arranged along the second direction B, so that the isolating switch can form a positive operating structure, and a user can operate the isolating switch in the front. In addition, the isolating switch can be further made to form a side operation structure, that is, the operating mechanism and the switch body can still be arranged along the second direction B, and the handle and the operating mechanism can be arranged along the direction perpendicular to the second direction B, for example, the first direction or the third direction, and the first direction, the second direction B and the third direction are perpendicular to each other in space, for example, as shown in fig. 10: the handle 310 and the operating mechanism 100 are arranged along the third direction C, and the operating mechanism 100 and the switch body 200 are arranged along the second direction B, so that the isolating switch is L-shaped as a whole, a side operating structure is formed, a user can operate the isolating switch from the side conveniently, and in addition, the handle 310 can be arranged along the first direction a with the operating mechanism 100, and therefore, the side operating structure can be correspondingly formed. As shown in fig. 11, for example: the arrangement direction of the handle 310 and the operating mechanism 100 is perpendicular to the arrangement direction of the operating mechanism 100 and the switch body 200, so that the isolating switch is L-shaped as a whole, thereby forming a side operating structure, and facilitating the operation of the isolating switch from the side of a user.
In some embodiments, the handle 310 may also adopt a rotation motion mode, that is, the user may drive the handle 310 to rotate around its own rotation axis, so as to drive the operating mechanism 100 and the switch body 200 to rotate, and in actual setting, as shown in fig. 3, the extending direction a of the rotation axis of the handle 310 is parallel to the extending direction B of the rotation axis of the operating mechanism 100, and of course, further, the extending direction a of the rotation axis of the handle 310 may also be parallel to the rotation axis c of the switch body 200, and the extending direction a of the rotation axis of the handle 310 may also be perpendicular to the stacking direction (i.e. the second direction B) of the operating mechanism 100 and the switch body 200. As shown in fig. 9 to 11, the extending direction a of the rotation axis of the handle 310 may be perpendicular to the extending direction b of the rotation axis of the operating mechanism 100, and of course, the extending direction a of the rotation axis of the handle 310 may be perpendicular to the rotation axis c of the switch body 200; in fig. 9, the extending direction a of the rotation axis of the handle 310 is also in the same direction as the stacking direction of the operating mechanism 100 and the switch body 200 (i.e., the second direction B), in fig. 10, the extending direction a of the rotation axis of the handle 310 is also perpendicular to the stacking direction of the operating mechanism 100 and the switch body 200 (i.e., the third direction C), and in fig. 11, the extending direction a of the rotation axis of the handle 310 is also perpendicular to the stacking direction of the operating mechanism 100 and the switch body 200.
In some embodiments, as shown in fig. 8, a release 340 may also be disposed on one side of the operating mechanism 100, where the release 340 has a driving portion 341 and the operating mechanism 100 has a driven portion 120, thereby facilitating the establishment of a driving relationship of the release 340 with the operating mechanism 100 via the driving portion 341 and the driven portion 120. When a circuit fault exists, the driving part 341 of the release 340 drives the driven part 120 to move, so that the operating mechanism 100 releases the button to open the gate, and the circuit is disconnected in time. As shown in fig. 8, a gap may be further provided between the driving portion 341 and the driven portion 120, so that when the release 340 operates, the driving portion 341 may firstly buffer by using the gap and then act on the driven portion 120 of the operating mechanism 100, so as to drive the operating mechanism 100 to release the brake. Through setting up the clearance, can effectively solve current isolator trouble and not trip or the unexpected phenomenon of tripping of no trouble.
In some embodiments, as shown in fig. 3 and 6, the isolating switch further includes a signal terminal 320, where the signal terminal 320 is electrically connected with the release 340, so that an instruction can be sent to the release 340 by the signal terminal 320, so that the release 340 can timely drive the operating mechanism 100 to release and break, that is, remote breaking control of the isolating switch is realized.
In some embodiments, as shown in fig. 7 and 8, the operating mechanism 100 may be accommodated in the housing 110, and meanwhile, the handle 310, the trip 340 and the signal terminal 320 may be matched and provided in the housing 110, and the operating mechanism 100 is a four-bar mechanism, so that the layout of the isolating switch of the present utility model can be well matched by means of the four-bar mechanism, and on the basis of ensuring the breaking consistency of the isolating switch, the stability of the opening and closing is effectively improved, and the development period is shortened. The present utility model is not particularly limited to the specific structure of the four-bar linkage. Of course, in other embodiments, the operating mechanism 100 may take various forms such as a rotary energy storage mechanism, a five-bar mechanism, a six-bar mechanism, etc.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
