[0002] The breaking device is an electrical device capable of controlling the on-off of current. The breaking device comprises a stationary contact and a moving contact. When the moving contact and the stationary contact are in contact, the circuit current of the breaking device is on, and the circuit works normally. When the moving contact and the stationary contact are out of contact, the circuit current of the breaking device is off.
[0003] In order to ensure good contact between the moving contact and the stationary contact, at present, two moving contact groups are generally provided, and each moving contact group comprises a plurality of moving contacts arranged side by side, so as to increase the contact area between the moving contact and the stationary contact and reduce the contact resistance.
[0004] Specifically, the two moving contact groups are oppositely arranged. In each moving contact group, two adjacent moving contacts are electrically connected by a connecting piece.
[0005] In the prior art, the connecting pieces included in the two moving contact groups often interfere with each other, which affects the cooperation distance between the two moving contact groups. CONTENT OF THE INVENTION
[0006] The present application provides a moving contact group, a moving contact structure and a breaking device, which are used to reduce the possibility of affecting the cooperation distance between the two moving contact groups.
[0007] In order to achieve the above-mentioned purpose, in a first aspect, the present application provides a moving contact group, which comprises a first moving contact group and a second moving contact group. The first moving contact group comprises a plurality of first moving contacts arranged in a first direction in sequence, and each first moving contact extends in a second direction. Two adjacent first moving contacts are electrically connected by a first connecting piece. The second moving contact group comprises a plurality of second moving contacts arranged in the first direction in sequence, and two adjacent second moving contacts are electrically connected by a second connecting piece. The first moving contact and the second moving contact are oppositely arranged in a third direction, and the first moving contact and the second moving contact can approach and move away from each other in the third direction. The first connecting piece is located on the side of the first moving contact facing the second moving contact, and the second connecting piece is located on the side of the second moving contact facing the first moving contact. In the second direction, the first connecting piece and the second connecting piece are arranged in a staggered manner; the first direction, the second direction and the third direction are perpendicular to each other.
[0008] When the above technical solutions are adopted, in the second direction, the first connecting piece and the second connecting piece are arranged in a staggered manner, the first connecting piece and the second connecting piece are prevented from contacting each other, the possibility that the fitting distance between the first movable contact group and the second movable contact group is affected is reduced, and it is ensured that the close fitting of the first movable contact group and the second movable contact group will not be affected by the first connecting piece and the second connecting piece.
[0009] In a possible implementation, the first movable contact is provided with a first accommodating groove on a side facing the second movable contact, and an end of the first connecting piece used for connecting the first movable contact is accommodated in the first accommodating groove.
[0010] When the above technical solutions are adopted, the two ends of the first connecting piece are accommodated in the first accommodating grooves of the two adjacent first movable contacts, the first connecting piece will not contact the second movable contact, the possibility that the fitting distance between the first movable contact group and the second movable contact group is affected is further reduced, and it is ensured that the close fitting of the first movable contact group and the second movable contact group will not be affected by the first connecting piece.
[0011] In a possible implementation, the second movable contact is provided with a second accommodating groove on a side facing the first movable contact, and an end of the second connecting piece used for connecting the second movable contact is accommodated in the second accommodating groove.
[0012] When the above technical solutions are adopted, the two ends of the second connecting piece are accommodated in the second accommodating grooves of the two adjacent second movable contacts, the second connecting piece will not contact the first movable contact, the possibility that the fitting distance between the first movable contact group and the second movable contact group is affected is further reduced, and it is ensured that the close fitting of the first movable contact group and the second movable contact group will not be affected by the first connecting piece.
[0013] In a possible implementation, a supporting column is arranged on the side of the first movable contact facing the second movable contact and / or on the side of the second movable contact facing the first movable contact.
[0014] When the above technical solutions are adopted, the arrangement of the supporting column makes the first movable contact and the second movable contact have a gap therebetween, the first connecting piece can be prevented from contacting the second movable contact, and the second connecting piece can be prevented from contacting the first movable contact, so as to reduce the possibility that the fitting distance between the first movable contact group and the second movable contact group is affected, and it is ensured that the close fitting of the first movable contact group and the second movable contact group will not be affected by the first connecting piece and the second connecting piece. Meanwhile, in specific implementation, the stationary contact can smoothly enter between the first movable contact and the second movable contact.
[0015] In a possible implementation, the first connecting piece is a copper wire or a silver wire; and the second connecting piece is a copper wire or a silver wire.
[0016] In a possible implementation, the moving contactor group includes a first moving contactor group and a second moving contactor group. The first moving contactor group includes a plurality of first moving contacts arranged in sequence along a first direction, and each first moving contact extends along a second direction. Two adjacent first moving contacts are electrically connected by a first connecting piece located between the two adjacent first moving contacts. The second moving contact group includes a plurality of second moving contacts arranged in sequence along the first direction, and the first moving contact and the second moving contact are oppositely arranged in a third direction and can approach or move away from each other in the third direction. Two adjacent second moving contacts are electrically connected by a second connecting piece located between the two adjacent second moving contacts. The first direction, the second direction, and the third direction are perpendicular to each other in pairs.
[0017] When the above technical solution is adopted, the first connecting piece is located between the two adjacent first moving contacts, and the second connecting piece is located between the two adjacent second moving contacts, thereby avoiding mutual interference between the first connecting piece and the second connecting piece, reducing the possibility that the cooperation distance between the first moving contact group and the second moving contact group is affected, and ensuring that the close cooperation of the first moving contact group and the second moving contact group is not affected by the first connecting piece and the second connecting piece.
[0018] In a possible implementation, in the two adjacent first moving contacts, one first moving contact is provided with a first accommodating groove on a side close to the other first moving contact, and an end of the first connecting piece used for connecting the first moving contact is accommodated in the first accommodating groove.
[0019] In a possible implementation, in the two adjacent second moving contacts, one second moving contact is provided with a second accommodating groove on a side close to the other second moving contact, and an end of the second connecting piece used for connecting the second moving contact is accommodated in the second accommodating groove.
[0020] When the above technical solution is adopted, the two ends of the first connecting piece are accommodated in the first accommodating grooves of the two adjacent first moving contacts, and the first connecting piece does not contact the second moving contact. At the same time, the two ends of the second connecting piece are accommodated in the second accommodating grooves of the two adjacent second moving contacts, and the second connecting piece does not contact the first moving contact. In this way, the possibility that the cooperation distance between the first moving contact group and the second moving contact group is affected is further reduced, and the close cooperation of the first moving contact group and the second moving contact group is ensured to be not affected by the first connecting piece.
[0021] In a possible implementation, a side of the first moving contact facing the second moving contact and / or a side of the second moving contact facing the first moving contact is provided with a supporting column.
[0022] When the above technical solution is used, the gap between the first moving contact and the second moving contact is formed by the support column, the first connecting piece can avoid contacting the second moving contact, and the second connecting piece can avoid contacting the first moving contact, so as to reduce the possibility that the matching distance between the first moving contact group and the second moving contact group is affected, and ensure that the close matching of the first moving contact group and the second moving contact group is not affected by the first connecting piece and the second connecting piece. Meanwhile, in specific implementation, the stationary contact can smoothly enter the gap between the first moving contact and the second moving contact.

The bearing frame has a cavity penetrating therethrough, and the moving contact group passes through the cavity at one end in the second direction. The limiting assembly is arranged on the bearing frame. The limiting assembly cooperates with the bearing frame to limit the moving contact group on the bearing frame. The elastic piece is used to apply a force to the first moving contact group and the second moving contact group included in the moving contact group to make them close to each other.

The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another.
[0048] The directional terms appearing in the following description are based on the directions shown in the drawings and do not limit the specific structure of the present application. For example, in the description of the present application, the terms "center", "lengthwise", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.
[0049] In addition, the terms "first", "second", and the like in the specification and claims of the present application or the above drawings are used to distinguish different objects, and are not used to describe a particular order, and can explicitly or implicitly include one or more of the features.
[0050] In the description of the present application, unless otherwise specified, "a plurality of" means two or more (including two), and similarly "a plurality of groups" means two or more groups (including two groups).
[0051] Firstly, the embodiment of the present application provides a breaking device, which is an electrical equipment capable of controlling current on-off.
[0052] It should be noted that the breaking device provided by the embodiment of the present application can be a circuit breaker or a disconnector.
[0053] The breaking device provided by the embodiment of the present application comprises a shell, a static contact and a moving contact structure as shown in Figure 1 , Figure 2 The static contact is used to contact the moving contact group as shown in Figure 3 and Figure 4 .
[0054] The static contact is arranged in the shell, and specifically, the static contact can be fixedly installed on the shell.
[0055] The fixed connection mode of the static contact and the shell is not specifically limited here. Exemplarily, the connection mode between the static contact and the shell can be screw connection, riveting, clamping or the like.
[0056] In combination with Figures 1 to 4 , the moving contact structure provided by the embodiment of the present application comprises a bearing frame 1, a limiting assembly 4, an elastic member 6 and a moving contact group for contacting the static contact, wherein the moving contact group comprises a first moving contact group 2 and a second moving contact group 3.
[0057] In actual cases, the moving contact structure is rotationally arranged in the shell. When the moving contact structure rotates relative to the shell, the first moving contact group 2 and the second moving contact group 3 can be switched between a contact position and a disengagement position.
[0058] When the first moving contact group 2 and the second moving contact group 3 are in the contact position, the first moving contact group 2 and the second moving contact group 3 both contact the static contact, and the first moving contact group 2 and the second moving contact group 3 are respectively located on two sides of the static contact, i.e., the first moving contact group 2 and the second moving contact group 3 respectively contact the opposite two side surfaces of the static contact, so that the circuit current of the breaking device is turned on.
[0059] When the first moving contact group 2 and the second moving contact group 3 are in the disengagement position, the first moving contact group 2 and the second moving contact group 3 both disengage from the static contact, so that the circuit current of the breaking device is turned off.
[0060] In specific implementation, the breaking device generally comprises two oppositely arranged static contacts. When the first moving contact group 2 and the second moving contact group 3 are in the contact position, the two ends of the first moving contact group 2 along the second direction respectively contact the two static contacts, and the two ends of the second moving contact group 3 along the second direction respectively contact the two static contacts, so that the circuit current of the breaking device is turned on.
[0061] When the first moving contact group 2 and the second moving contact group 3 are in the disengaged position, both ends of the first moving contact group 2 in the second direction are out of contact with the two static contacts, and both ends of the second moving contact group 3 in the second direction are out of contact with the two static contacts, so that the circuit current of the breaking device is disconnected.
[0062] In an example, as shown in Figures 1 to 6 The first moving contact group 2 includes a plurality of first moving contacts 21 arranged in sequence in the first direction, and the first moving contacts 21 extend in the second direction. The second moving contact group 3 includes a plurality of second moving contacts 31 arranged in sequence in the first direction, and the first moving contacts 21 and the second moving contacts 31 are oppositely arranged in the third direction.
[0063] In particular implementation, the number of the first moving contacts 21 included in the first moving contact group 2 is not limited here and can be determined according to actual conditions.
[0064] For example, the number of the first moving contacts 21 can be two, three, four, or more.
[0065] In the embodiments provided in the present application, the number of the first moving contacts 21 is two.
[0066] In actual conditions, the first moving contact 21 can have a cuboid structure, and the length direction of the first moving contact 21 is parallel to the second direction.
[0067] In addition, it should be noted that the first moving contact 21 is provided with a first moving contact point, and the first moving contact point is arranged on the side of the first moving contact 21 facing the second moving contact 31. Moreover, the first moving contact point is arranged on both ends of the first moving contact 21 in the second direction. The first moving contact point is used to contact the static contact.
[0068] Similarly, the number of the second moving contacts 31 included in the second moving contact group 3 is not limited here and can be determined according to actual conditions.
[0069] For example, the number of the second moving contacts 31 can be two, three, four, or more.
[0070] The number of the first moving contacts 21 and the number of the second moving contacts 31 can be the same or different.
[0071] In the embodiments provided in the present application, the number of the first moving contacts 21 and the number of the second moving contacts 31 are the same, and both are two.
[0072] In actual conditions, the structure of the second moving contact 31 is the same as that of the first moving contact 21, and both are cuboid structures, and the length direction of the second moving contact 31 is parallel to the second direction.
[0073] In addition, it should be noted that the second movable contact head 31 is provided with a second movable contact point, and the second movable contact point is arranged on the side of the second movable contact head 31 facing the first movable contact head 21. In addition, the second movable contact head 31 is provided with a second movable contact point at each end in the second direction. The second movable contact point is used to contact the static contact head.
[0074] The first movable contact head 21 and the second movable contact head 31 can move closer to and away from each other in the third direction.
[0075] In actual cases, in order to realize the function of the first movable contact head 21 and the second movable contact head 31 moving closer to and away from each other in the third direction, the first movable contact head 21 can be relatively static, and the second movable contact head 31 can move in the third direction. Of course, the second movable contact head 31 can also be relatively static, and the first movable contact head 21 can move in the third direction. In addition, the first movable contact head 21 and the second movable contact head 31 can also move in the third direction.
[0076] In the embodiments provided in the present application, the first movable contact head 21 and the second movable contact head 31 can move in the third direction.
[0077] It should be noted that when the first movable contact head 21 and the second movable contact head 31 move closer to and away from each other in the third direction, the plurality of first movable contact heads 21 do not interfere with each other, that is, any one of the plurality of first movable contact heads 21 can move in the third direction independently.
[0078] Similarly, when the first movable contact head 21 and the second movable contact head 31 move closer to and away from each other in the third direction, the plurality of second movable contact heads 31 do not interfere with each other, that is, any one of the plurality of second movable contact heads 31 can move in the third direction independently.
[0079] The first movable contact head 21 and the second movable contact head 31 are arranged opposite to each other in the third direction. The first movable contact head 21 and the second movable contact head 31 are parallel to each other, and the length direction of the first movable contact head 21 and the second movable contact head 31 are parallel to the second direction. In addition, the side of the first movable contact head 21 close to the second movable contact head 31 can be perpendicular to the third direction, and the side of the second movable contact head 31 close to the first movable contact head 21 can be perpendicular to the third direction.
[0080] The two adjacent first movable contact heads 21 are electrically connected through the first connecting piece 22, and the two ends of the first connecting piece 22 are respectively electrically connected with the two adjacent first movable contact heads 21. The two adjacent second movable contact heads 31 are electrically connected through the second connecting piece 32, and the two ends of the second connecting piece 32 are respectively electrically connected with the two adjacent second movable contact heads 31.
[0081] In practice, the first connecting member 22 can be a flexible conductive connecting member. The flexible conductive connecting member can be bent at will to change the extending direction. In this way, when any one of the plurality of first movable contacts 21 moves in the third direction, the movement of other first movable contacts 22 will not be interfered.
[0082] Similarly, the second connecting member 32 is a flexible conductive connecting member. In this way, when any one of the plurality of second movable contacts 31 moves in the third direction, the movement of other second movable contacts 31 will not be interfered.
[0083] In practice, the first connecting member can be a copper wire or a silver wire, and the second connecting member can be a copper wire or a silver wire. Of course, this is only an example and is not a specific limitation.
[0084] In combination Figure 3 and Figure 4 As shown in the drawings, the first connecting member 22 is located on the side of the first movable contact 21 facing the second movable contact 31, and the second connecting member 32 is located on the side of the second movable contact 31 facing the first movable contact 21. In the second direction, the first connecting member 22 and the second connecting member 32 are arranged in a staggered manner.
[0085] It should be noted that, as described above, the first movable contact 21 is provided with a first movable contact point, which is arranged on the side of the first movable contact 21 facing the second movable contact 31. The second movable contact 31 is provided with a second movable contact point, which is arranged on the side of the second movable contact 31 facing the first movable contact 21.
[0086] When the first movable contact group 2 and the second movable contact group 3 are in the disengaged position, the first movable contact point can be in contact with the second movable contact point, so that the first movable contact 21 and the second movable contact 31 have a gap, which can accommodate the first connecting member 22 and the second connecting member 32.
[0087] In the second direction, the first connecting member 22 and the second connecting member 32 are arranged in a staggered manner, avoiding mutual interference between the first connecting member 22 and the second connecting member 32, reducing the possibility of affecting the cooperation distance between the first movable contact group 2 and the second movable contact group 3, and ensuring that the close cooperation of the first movable contact group 2 and the second movable contact group 3 will not be affected by the first connecting member 22 and the second connecting member 32.
[0088] The first direction, the second direction, and the third direction are perpendicular to each other. It should be noted that in the embodiments provided in the present application, the first direction, the second direction, and the third direction are only to facilitate the description of the positional relationship between the various components included in the movable contact structure, and are not a specific limitation of the present application.
[0089] As an optional way, as Figure 3 and Figure 4As shown, the side of the first moving contact 21 facing the second moving contact 31 is provided with a first accommodating groove 212, and the end of the first connecting piece 22 used for connecting the first moving contact 21 is accommodated in the first accommodating groove 212.
[0090] At this time, the two ends of the first connecting piece 22 are respectively accommodated in the first accommodating grooves 212 of the two adjacent first moving contacts 21, the first connecting piece 22 will not contact the second moving contact 31, further reducing the possibility that the matching interval between the first moving contact group 2 and the second moving contact group 3 is affected, and ensuring that the close matching of the first moving contact group 2 and the second moving contact group 3 will not be affected by the first connecting piece 22.
[0091] As another alternative, as shown in Figure 3 As shown, the side of the second moving contact 31 facing the first moving contact 21 is provided with a second accommodating groove 312, and the end of the second connecting piece 32 used for connecting the second moving contact 31 is accommodated in the second accommodating groove 312.
[0092] At this time, the two ends of the second connecting piece 32 are respectively accommodated in the second accommodating grooves 312 of the two adjacent second moving contacts 31, the second connecting piece 32 will not contact the first moving contact 21, further reducing the possibility that the matching interval between the first moving contact group 2 and the second moving contact group 3 is affected, and ensuring that the close matching of the first moving contact group 2 and the second moving contact group 3 will not be affected by the first connecting piece 22.
[0093] Please refer to Figures 1 to 6 , the side of the first moving contact 21 facing the second moving contact 31 and / or the side of the second moving contact 31 facing the first moving contact 21 is provided with a support column 5.
[0094] The support column 5 is provided so that there is a gap between the first moving contact 21 and the second moving contact 31, which can avoid the first connecting piece 22 from contacting the second moving contact 31, and can avoid the second connecting piece 32 from contacting the first moving contact 21, so as to reduce the possibility that the matching interval between the first moving contact group 2 and the second moving contact group 3 is affected, and ensure that the close matching of the first moving contact group 2 and the second moving contact group 3 will not be affected by the first connecting piece 22 and the second connecting piece 32.
[0095] In specific implementation, the support column 5 can be provided only on the first moving contact 21, one end of the support column 5 is fixedly provided on the first moving contact 21, and the other end of the support column 5 can be supported on the second moving contact 31 when the first moving contact group 2 and the second moving contact group 3 are in the disengaged position.
[0096] The support column 5 can also be arranged on the second moving contact 31 only, one end of the support column 5 being fixedly arranged on the second moving contact 31, and the other end of the support column 5 being capable of being supported on the first moving contact 21 when the first moving contact group 2 and the second moving contact group 3 are in the disengaged position.
[0097] Of course, the support column 5 can also be arranged on both the first moving contact 21 and the second moving contact 31. Moreover, the support column 5 arranged on the first moving contact 21 and the support column 5 arranged on the second moving contact 31 can be arranged in a staggered manner.
[0098] At this time, the other end of the support column 5 arranged on the first moving contact 21 can be supported on the second moving contact 31, and the other end of the support column 5 arranged on the second moving contact 31 can be supported on the first moving contact 21 when the first moving contact group 2 and the second moving contact group 3 are in the disengaged position.
[0099] When the support column 5 is arranged on both the first moving contact 21 and the second moving contact 31, the support column 5 arranged on the first moving contact 21 and the support column 5 arranged on the second moving contact 31 can also be arranged in a relative manner.
[0100] At this time, the other end of the support column 5 arranged on the first moving contact 21 can be supported on one end of the support column 5 arranged on the second moving contact 31 in a relative manner when the first moving contact group 2 and the second moving contact group 3 are in the disengaged position.
[0101] The number of the support column 5 is not limited here.
[0102] In addition, the arrangement position of the support column 5 is also not limited here, as long as a gap is ensured between the first moving contact 21 and the second moving contact 31 arranged in a relative manner, and the arrangement of the support column 5 does not interfere with the stationary contact.
[0103] When the support column 5 is arranged on the first moving contact 21, the support column 5 can be welded or threadedly connected on the first moving contact 21. Of course, the support column 5 can also be formed on the first moving contact 21 by stamping in an integrated manner.
[0104] Correspondingly, when the support column 5 is arranged on the second moving contact 31, the support column 5 can be welded or threadedly connected on the second moving contact 31. Of course, the support column 5 can also be formed on the second moving contact 31 by stamping in an integrated manner.
[0105] In another example, as shown in FIG. 6, the support column 5 is arranged on the first moving contact 21 only. Figure 1 and Figure 2As shown, the first moving contact group 2 includes a plurality of first moving contacts 21 arranged in sequence along a first direction, the first moving contacts 21 extending along a second direction. Two adjacent first moving contacts 21 are electrically connected by a first connecting piece, the first connecting piece being located between the two adjacent first moving contacts 21.
[0106] The second moving contact group 3 includes a plurality of second moving contacts 31 arranged in sequence along the first direction, the first moving contacts 21 and the second moving contacts 31 being oppositely arranged in a third direction, and the first moving contacts 21 and the second moving contacts 31 being capable of approaching and moving away from each other in the third direction. Two adjacent second moving contacts 31 are electrically connected by a second connecting piece, the second connecting piece being located between the two adjacent second moving contacts 31. The first direction, the second direction, and the third direction are perpendicular to each other.
[0107] In this way, the first connecting pieces are located between the two adjacent first moving contacts 31, and the second connecting pieces are located between the two adjacent second moving contacts 31, so that the first connecting pieces and the second connecting pieces do not interfere with each other, reducing the possibility that the fitting distance between the first moving contact group 2 and the second moving contact group 3 is affected, and ensuring that the close fitting of the first moving contact group 2 and the second moving contact group 3 is not affected by the first connecting pieces and the second connecting pieces.
[0108] In specific implementation, in the second direction, the first connecting pieces and the second connecting pieces can be arranged in a staggered manner to avoid the phenomenon of mutual interference of the first connecting pieces and the second connecting pieces.
[0109] Further, in the two adjacent first moving contacts, one of the first moving contacts is provided with a first accommodating groove on the side close to the other first moving contact, and the end of the first connecting piece used for connecting the first moving contact is accommodated in the first accommodating groove.
[0110] In the two adjacent second moving contacts, one of the second moving contacts is provided with a second accommodating groove on the side close to the other second moving contact, and the end of the second connecting piece used for connecting the second moving contact is accommodated in the second accommodating groove.
[0111] At this time, the two ends of the first connecting piece are respectively accommodated in the first accommodating grooves of the two adjacent first moving contacts, and the first connecting piece does not contact the second moving contacts. At the same time, the two ends of the second connecting piece are respectively accommodated in the second accommodating grooves of the two adjacent second moving contacts, and the second connecting piece does not contact the first moving contacts. In this way, the possibility that the fitting distance between the first moving contact group and the second moving contact group is affected is further reduced, and the close fitting of the first moving contact group and the second moving contact group is ensured not to be affected by the first connecting pieces.
[0112] As a feasible manner, as Figure 1 and Figure 2As shown in the figures, the side of the first moving contact 21 facing the second moving contact 31 and / or the side of the second moving contact 31 facing the first moving contact 21 is provided with a support column 5.
[0113] In this way, the provision of the support column 5 allows a gap between the first moving contact group 2 and the second moving contact group 3, which can avoid the first connecting piece 22 from contacting the second moving contact 31 and the second connecting piece 32 from contacting the first moving contact 21, so as to reduce the possibility of the matching distance between the first moving contact group 2 and the second moving contact group 3 being affected, and ensure that the close matching of the first moving contact group 2 and the second moving contact group 3 will not be affected by the first connecting piece 22 and the second connecting piece 32. Meanwhile, in actual work, it is beneficial to the smooth entry of the static contact into the first moving contact 21 and the second moving contact 31.
[0114] In a possible implementation, in combination with Figure 1 , Figure 2 and Figure 7 As shown in the figures, the carrier 1 has a through cavity 11. The moving contact group passes through the cavity 11 at one end in the second direction. The limiting assembly 4 is arranged on the carrier 1. The limiting assembly 4 cooperates with the carrier 1 to limit the moving contact group on the carrier 1. The elastic member 6 is used to apply a force to the first moving contact group 2 and the second moving contact group 3 included in the moving contact group to make them close to each other.
[0115] The carrier 1 is used to carry the first moving contact group 2, the second moving contact group 3, the limiting assembly 4 and the elastic member 6. The carrier 1 provides stable support for the first moving contact group 2, the second moving contact group 3, the limiting assembly 4 and the elastic member 6, and integrates the first moving contact group 2, the second moving contact group 3 and the limiting assembly 4 together.
[0116] In actual cases, the carrier 1 is rotationally connected with the shell. The first moving contact group 2, the second moving contact group 3, the limiting assembly 4 and the elastic member 6 all rotate synchronously with the carrier 1 relative to the shell.
[0117] The specific structure of the carrier 1 is not limited here, and exemplarily, the carrier 1 can be a cuboid structure or a multi-prism structure.
[0118] In the embodiments provided in the present application, as shown in Figure 1 , Figure 2 and Figure 7 The carrier 1 is a column structure. The carrier 1 has a through cavity 11, and the cavity 11 penetrates the carrier 1 in the second direction, and the rotation axis of the carrier 1 extends in the third direction. The structure of the cavity 11 is not limited here, and is subject to actual conditions.
[0119] One end of the first moving contact 21 along the second direction passes through the cavity 11. At this time, the middle region of the first moving contact 21 is located in the cavity 11, and both ends of the first moving contact 21 are located outside the cavity 11, so that both the first moving contact points arranged at both ends of the first moving contact 21 can be in contact with the static contact.
[0120] One end of the second moving contact 31 along the second direction passes through the cavity 11. At this time, the middle region of the second moving contact 31 is located in the cavity 11, and both ends of the second moving contact 31 are located outside the cavity 11, so that both the second moving contact points arranged at both ends of the second moving contact 31 can be in contact with the static contact.
[0121] In the embodiments provided in the present application, the first moving contact 21 is slidingly arranged in the carrier 1 along the third direction, and the first moving contact 21 can slide relative to the carrier 1 in the third direction.
[0122] Meanwhile, the second moving contact 31 is slidingly arranged in the carrier 1 along the third direction, and the second moving contact 31 can slide relative to the carrier 1 in the third direction. When the first moving contact 21 and the second moving contact 31 slide relative to the carrier 1 in the third direction, the first moving contact 21 and the second moving contact 31 can approach and move away from each other in the third direction.
[0123] The limiting component 4 is arranged in the carrier 1, and the limiting component 4 cooperates with the carrier 1 to limit the moving contact group on the carrier 1. That is, the limiting component 4 and the carrier 1 cooperate to limit the moving contact group in the first direction, the second direction and the third direction, so as to prevent the first moving contact group 2 and the second moving contact group 3 from being separated from the carrier 1.
[0124] In addition, the elastic member 6 is used to apply a force of approaching each other to the first moving contact group 2 and the second moving contact group 3. Specifically, the elastic member 6 is used to apply a force of approaching each other to the first moving contact 21 and the second moving contact 31.
[0125] The elastic member 6 can be a spring sheet or a spring, which is not limited here and can be determined according to actual conditions.
[0126] When the first moving contact group 2 and the second moving contact group 3 are switched from the disengagement position to the contact position under the driving of the bearing frame 1, when the first moving contact 21 and the second moving contact 31 are in contact with the static contact, the static contact enters between the first moving contact 21 and the second moving contact 31, so that the first moving contact 21 and the second moving contact 31 slide in the third direction to the opposite direction relative to the bearing frame 1, and the first moving contact 21 and the second moving contact 31 are away from each other in the third direction. The bearing frame 1 continues to drive the first moving contact group 2 and the second moving contact group 3 to rotate relative to the shell until the first moving contact group 2 and the second moving contact group 3 are in the contact position, and the first moving contact group 2 and the second moving contact group 3 are in stable contact with the static contact.
[0127] It can be understood that, since the static contact is fixedly arranged relative to the shell, during the switching of the first moving contact group 2 and the second moving contact group 3 from the disengagement position to the contact position, the first moving contact 21 and the second moving contact 31 can slide in the third direction to the opposite direction relative to the bearing frame 1, so as to cooperate with the position of the static contact, and realize good contact between the first moving contact 21 and the second moving contact 31 and the static contact.
[0128] In the embodiments provided in the present application, the number of the first moving contacts 21 is multiple, and the number of the first moving contacts in close contact with the static contact at one end of the first moving contact group 2 is multiple, which can increase the contact area of the first moving contact group 2 with the static contact. At the same time, the number of the second moving contacts 31 is multiple, and the number of the second moving contacts in close contact with the static contact at one end of the second moving contact group 3 is multiple, which can increase the contact area of the second moving contact group 3 with the static contact, ensure good contact between the first moving contact group 2 and the second moving contact group 3 and the static contact, and reduce the contact resistance.
[0129] In the prior art, in order to ensure good contact between the moving contact and the static contact, the cross-sectional area of the moving contact is generally increased, that is, the size of the moving contact in the first direction is increased. At this time, a larger space needs to be reserved in the shell for the moving contact, which increases the occupied space of the breaking device.
[0130] In the embodiments provided in the present application, the original moving contact can be divided into multiple moving contacts in the first direction without changing the size of the moving contact in the first direction, so as to form the first moving contact group 2 or the second moving contact group 3.
[0131] Therefore, the occupied space of the movable contact is not increased, and when the first movable contact group 2 and the second movable contact group 3 are in the contact position, the plurality of first movable contacts 21 can be ensured to simultaneously contact the static contact, and similarly, the plurality of second movable contacts 31 can be ensured to simultaneously contact the static contact, thereby increasing the contact area and reducing the contact resistance.
[0132] Therefore, the movable contact structure provided by the embodiment of the application can ensure good contact between the movable contact and the static contact, without increasing the occupied space and reducing the possibility of increasing the occupied space of the breaking device.
[0133] As an implementation manner, as shown in Figure 1 , Figure 2 , Figure 5 and Figure 6 , the limiting assembly 4 includes a first limiting frame 41, a second limiting frame 42 and a third limiting frame 43, and the first limiting frame 41 is slidingly arranged on the bearing frame 1 along the third direction.
[0134] The bearing frame 1 can limit the first limiting frame 41 in the third direction. In actual implementation, a guide structure can be arranged on the first limiting frame 41 and the bearing frame 1 to cooperate with each other, and the guide structure can include a sliding block and a guide rail that cooperate with each other. Of course, the actual implementation is not limited thereto.
[0135] One side of the first limiting frame 41 along the second direction is limited by the third limiting frame 43, and the other side of the first limiting frame 41 along the second direction is limited by the bearing frame 1.
[0136] In an example, the first limiting frame 41 has a first bearing surface, and the first movable contact 21 is limited on the first bearing surface.
[0137] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 8 , one of a first recess 211 and a first protrusion 4111 is arranged on the first bearing surface, and the other of the first recess 211 and the first protrusion 4111 is arranged on the first movable contact 21.
[0138] Therefore, when the first movable contact 21 is arranged on the first bearing surface, the first recess 211 and the first protrusion 4111 cooperate to limit the position of the first movable contact. When the first limiting frame 41 slides relative to the bearing frame 1 along the third direction, the first movable contact 21 is simultaneously driven to slide relative to the bearing frame 1 along the third direction.
[0139] The second limiting frame 42 is slidingly arranged on the bearing frame 1 along the third direction.
[0140] The carrier frame 1 can limit the second limiting frame 42 in the third direction. In specific implementation, the second limiting frame 42 and the carrier frame 1 can be provided with guiding structures matched with each other, which can include matched sliding blocks and guide rails. Of course, the actual implementation is not limited thereto.
[0141] The side of the second limiting frame 42 along the second direction is limited by the third limiting frame 43, and the other side of the second limiting frame 42 along the second direction is limited by the carrier frame 1.
[0142] In an example, the second limiting frame 42 has a second bearing surface, the first bearing surface and the second bearing surface are oppositely arranged, and the second movable contact 31 is limited by the second bearing surface.
[0143] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 9 , it is shown that the second bearing surface is provided with one of a second recess 311 and a second protrusion 4211 matched with each other, and the second movable contact 31 is provided with the other of the second recess 311 and the second protrusion 4211.
[0144] In this way, when the second movable contact 31 is arranged on the second bearing surface, the second recess 311 and the second protrusion 4211 are matched to limit the position of the second movable contact 31. When the second limiting frame 42 slides relative to the carrier frame 1 along the third direction, the second movable contact 31 is synchronously driven to slide relative to the carrier frame 1 along the third direction.
[0145] In some embodiments, in combination with Figure 2 and Figure 8 , it is shown that the first limiting frame 41 includes a first bearing portion 411, a first limiting portion 412 and a first supporting portion 413 connected with each other.
[0146] In specific implementation, the first bearing portion 411, the first limiting portion 412 and the first supporting portion 413 can all be plate-shaped structures.
[0147] The first bearing portion 411, the first limiting portion 412 and the first supporting portion 413 surround to form a first U-shaped space, the second limiting frame 42 is arranged in the first U-shaped space, and one side of the first bearing portion 411 close to the first supporting portion 413 is the first bearing surface. One end of the elastic member 6 elastically acts on the first supporting portion 413.
[0148] In specific implementation, the first limiting frame 41 is at least partially located in the cavity 11, and both sides of the first limiting frame 41 along the first direction are limited by the cavity side walls. The side of the first bearing portion 411 away from the first movable contact 21 is limited by the cavity bottom wall. The side of the first supporting portion 413 away from the first movable contact 21 can be limited by one end of the elastic member 6 or the cavity top wall.
[0149] One side of the first limiting part 412 along the second direction is limited by the third limiting frame 43, and the other side of the first limiting part 412 along the second direction is limited by the bearing frame 1, thereby limiting the first limiting frame 41 on the bearing frame 1.
[0150] In an example, in combination with Figure 2 , Figure 9 and Figure 10 , the second limiting frame 42 comprises a second bearing part 421 and a second limiting part 422 connected with each other, and the second bearing part 421 and the second limiting part 422 form an L-shaped structure. The second bearing part 421 is a second bearing surface close to the second moving contact group 3.
[0151] The second limiting part 422 is arranged on the two sides of the first moving contact group 2 along the first direction respectively. The other end of the elastic member 6 elastically acts on the second bearing part 421. One side of the second limiting part 422 along the second direction is limited by the third limiting frame 43, and the other side of the second limiting part 422 along the second direction is limited by the bearing frame 1.
[0152] In practice, the elastic member 6 is a spring sheet as shown in Figure 2 . For example, the placement orientation shown in Figure 2 , the structure of the elastic member 6 is M-shaped, one end of the elastic member 6 elastically contacts the side of the first supporting part 413 close to the first moving contact 21, and the other end of the elastic member 6 elastically contacts the side of the second limiting part 422 away from the first moving contact 21.
[0153] Specifically, when the static contact is located between the first moving contact 21 and the second moving contact 31, under the action of the elastic member 6, the second bearing part 421 has an action force close to the first moving contact 21. For example, the placement orientation shown in Figure 1 and Figure 2 , the second bearing part 421 has an action force downward along the third direction. The second bearing part 421 drives the second moving contact 31 to close to the first moving contact 21, and since the static contact is located between the first moving contact 21 and the second moving contact 31, that is, the second moving contact 31 has an action force close to the static contact, the second moving contact 31 is in close contact with the static contact.
[0154] Under the action of the elastic member 6, the first supporting part 413 has an action force away from the second bearing part 421. For example, the placement orientation shown in Figure 1 and Figure 2The shown placement orientation is an example, the second bearing part 421 has an upward force along the third direction. Further, the first bearing part 411 is driven by the first limiting part 412 to move towards the second moving contact 31, and the first moving contact 21 is synchronously driven by the first bearing part 411 to move towards the second moving contact 31, that is, the first moving contact 21 is driven to move upward along the third direction. Since the static contact is located between the first moving contact 21 and the second moving contact 31, the static contact is in close contact with the first moving contact 21. In this way, the first moving contact 21 and the second moving contact 31 can be in close contact with the static contact.
[0155] As an example, as shown in Figure 10 The side of the second bearing part 421 away from the second limiting part 422 is provided with two first extension parts 423 arranged oppositely, in combination with Figure 5 、 Figure 8 and Figure 10 , the two first extension parts 423 are used for limiting contact with the two sides of the first limiting part 412 along the second direction.
[0156] In this way, the stability of the interaction between the first limiting frame 41 and the second limiting frame 42 is improved, and the structural integrity of the moving contact structure provided by the embodiment of the application is improved.
[0157] In a possible implementation, the bearing frame 1 has two clamping surfaces 12 arranged oppositely, and the two clamping surfaces 12 are sequentially arranged along the first direction.
[0158] Referring to Figure 2 The third limiting frame 43 includes a connecting part 431 and two clamping parts 432 arranged oppositely, and the two clamping parts 432 are respectively located on the two sides of the connecting part 431 along the first direction. The connecting part 431 and the clamping part 432 surround to form a second U-shaped space.
[0159] The first limiting part 412 and the second limiting part 422 are located on the side of the connecting part 431 close to the clamping part 432 along the second direction.
[0160] The connecting part 431 is provided with a through hole 4311 in communication with the cavity 11, and one end of the first moving contact group 2 and the second moving contact group 3 along the second direction sequentially passes through the through hole 4311 and the cavity 11.
[0161] The distance between the two clamping parts 432 is less than the distance between the two clamping surfaces 12, and the two clamping parts 432 can be clamped on the clamping surface 12, so as to clamp the third limiting frame 43 on the bearing frame 1, thereby installing the third limiting frame 43 on the bearing frame 1.
[0162] In implementation, one side of the first limiting portion 412 along the second direction is limited by the connecting portion 431, and the other side of the first limiting portion 412 along the second direction is limited by the bearing frame 1.
[0163] Specifically, in combination with Figure 1 , Figure 2 and Figure 7 , the other side of the first limiting portion 412 along the second direction is limited by the limiting cavity wall 15 of the cavity 11 away from the connecting portion 431, so that the position of the first limiting frame 41 in the second direction is limited.
[0164] Similarly, one side of the second limiting portion 422 along the second direction is limited by the connecting portion 431, and the other side of the second limiting portion 422 along the second direction is limited by the bearing frame 1.
[0165] Specifically, in combination with Figure 1 , Figure 2 and Figure 7 , the other side of the second limiting portion 422 along the second direction is limited by the limiting cavity wall 15 of the cavity 11 away from the connecting portion 431, so that the position of the second limiting frame 42 in the second direction is limited.
[0166] In implementation, the connecting portion 431 is provided with a second extension portion 433, the second extension portion 433 is arranged on the side of the connecting portion 431 close to the elastic member 6, and the second extension portion 433 extends from the connecting portion 431 along the second direction. The second extension portion 433 is located on the side of the connecting portion 431 provided with the clamping portion 432.
[0167] The side of the second extension portion 433 close to the first moving contact 21 is used to contact the second limiting portion 422 to limit the movement distance of the second limiting frame 42 in the third direction.
[0168] The first supporting portion 413 can limit the position of the elastic member 6 in the second direction. At the same time, the top of the M-shaped elastic member 6 can be limited in the top of the through hole 4311 to prevent the elastic member 6 from being dislocated.
[0169] In one possible way, one of the third protruding portion 13 and the third recessed portion corresponding to each other is arranged on the clamping portion 432 corresponding to the clamping face 12, and the other one of the third protruding portion 13 and the third recessed portion is arranged on the clamping face 12.
[0170] In this way, when the third limiting frame 43 is arranged on the bearing frame 1, the third protruding portion 13 and the third recessed portion can limit the position of the third limiting frame 43 on the bearing frame 1, and enhance the firmness of the third limiting frame 43 installed on the bearing frame 1.
[0171] In the embodiment, the third protruding part is arranged on the clamping surface 12, and the third recessed part is arranged on the clamping part 432.
[0172] In the embodiment provided in the application, as shown in the drawings, the third protruding part 13 is arranged on the clamping surface 12, and the clamping groove 4321 matched with the third protruding part 13 is arranged on the clamping part 432. Figures 1 to 3
