Description

Technical Field

[0001] The utility model relates to the field of low-voltage electrical appliances, in particular to an operating device and a switch device comprising the operating device. Background Art

[0002] The switch device is used for closing and opening the circuit, and includes an operating device and at least one contact system. The operating device includes an operating mechanism and a contact support transmission-connected to the operating mechanism. The contact support carries the moving contact of the contact system. The operating mechanism drives the contact support to drive the moving contact and the stationary contact of the contact system to close and open. The electrical performance of the switch device is closely related to the opening distance of the moving contact and the stationary contact after the disconnection.

[0003] The operating mechanism of the existing switch device has an energy storage spring with one end fixed and the other end being a movable end connected to the main shaft to complete energy storage and energy release. When the energy storage spring releases energy, it drives the main shaft to rotate and the main shaft drives the moving contact structure to rotate through the output shaft. This method results in a limited rotation angle of the output shaft, and it is impossible to further increase the opening distance after the moving contact structure and the static contact structure are disconnected, which affects the improvement of the electrical performance of the switch device, and the overall space occupied is large; moreover, the moving contact is often closed and disconnected with the static contact by rotation, and the required action space is large. In addition, the existing switch device is also provided with an arc extinguishing chamber for extinguishing the arc, but the effect of the contact system driving the arc into the arc extinguishing chamber is not good. In addition, the existing switch device is also provided with an auxiliary module, and the structure and transmission relationship of the switch device driving the auxiliary module to switch the working state are complex and have poor reliability. In addition, the existing switch device lacks a structure for judging the current position of the moving contact. When the moving contact and the static contact fail to disconnect (for example, the moving contact and the static contact are welded and cannot be disconnected), it is easy to cause the operator to misjudge and threaten the personal safety of the operator.

The moving contact and the static contact can be quickly disconnected and closed through the main contact support, thereby eliminating or significantly reducing the possibility of arcing when the moving contact and the static contact are closed and disconnected. Moreover, compared with the existing method of directly driving the main contact support through the rotating shaft, the operating mechanism can significantly increase the rotation angle of the connecting rod within a limited space, thereby increasing the movement of the main contact support matched with the transmission, increasing the opening distance between the moving contact and the static contact, and having good action performance, and making the structure of the operating mechanism more compact and smaller in size. Moreover, the connecting rod drives the main contact support to move linearly through the driving shaft, which is conducive to reducing the space required for the main contact support action.

[0041] In addition, the static contact is an L-shaped structure, and the electromagnetic force at the bent connection between the static terminal plate and the static contact knife of the static contact drives the arc separated by the static contact and the moving contact to move into the arc extinguishing chamber, ensuring that the arc is completely or mostly extinguished after entering the arc extinguishing chamber, and preventing the arc from moving toward the operating mechanism.

[0042] In addition, the transmission mode and structure of the auxiliary module and the active contact mechanism are simple and reliable, ensuring that the auxiliary module works reliably.

[0043] In addition, the switch opening and closing indication structure cooperates with the indication window, which is beneficial for the operator to judge the current position of the main contact support, so as to judge whether the moving contact and the static contact of the moving contact mechanism are disconnected, thereby improving the safety of electricity use.

DETAILED DESCRIPTION

[0078] The following is a further description of the specific implementation of the switch device of the present utility model in conjunction with the embodiments given in the accompanying drawings. The switch device of the present utility model is not limited to the description of the following embodiments.

[0079] like Figure 1-6 FIG. 1 is an embodiment of the switch device of the present utility model.

[0080] The switch device of this embodiment includes a switch body z, which includes an operating device and at least one group of contact systems. The operating device includes an operating mechanism m and a main contact support 5-0. The contact system includes a moving contact 5-1 and a main static contact mechanism 6 used in conjunction with each other. The moving contact 5-1 is carried on the main contact support 5-0. The main static contact mechanism 6 includes at least one static contact 6-0. The operating mechanism m is connected to the main contact support 5-0 by transmission to drive the main contact support 5-0 to move linearly. The main contact support 5-0 drives the moving contact 5-1 to close and disconnect with the static contact 6-00, thereby closing and opening the switch body z. Further, the main static contact mechanism 6 includes two groups of static contacts 6-00 respectively arranged on both sides of the main contact support 5-0. The operating mechanism m drives the main contact support 5-0 to move linearly. The main contact support 5-0 drives the moving contact 5-1 to move linearly so that the two ends of the moving contact 5-1 are closed and disconnected with the two groups of static contacts 6-00 respectively.

[0081] Furthermore, the switch device of this embodiment further includes an active contact mechanism 5, and the active contact mechanism 5 includes a main contact support 5-0 and a moving contact 5-1 carried by the main contact support 5-0.

[0082] Specifically, the switch device of this embodiment includes two or more contact systems, and the movable contacts 5-1 of each contact system are all carried on the main contact support 5-0. The number of the contact systems can be adjusted according to actual needs. For example, if the switch device of this embodiment is a single-phase switch, the number of the contact system is one, if the switch device of this embodiment is a two-phase switch, the number of the contact systems is two, if the switch device of this embodiment is a three-phase switch, the number of the contact systems is three, and if the switch device of this embodiment is a three-phase four-wire switch, the number of the contact systems is four.

[0083] Furthermore, the switch device of this embodiment further comprises a main body shell h, and the operating device and the contact system are both arranged in the main body shell h. Further, the main body shell h comprises an upper cover h-1 and a base h-2 which are relatively assembled together along the moving direction of the main contact support 5-0 (that is, the extension direction of the axis ss mentioned later and the height direction d3 of the switch device, which will be described later).

[0084] Furthermore, the switch device of this embodiment also includes an auxiliary module f used in conjunction with the switch body z. When the operating mechanism m drives the active contact mechanism 5 to move linearly to switch the switch body z between the closed state and the open state, the active contact mechanism 5 simultaneously drives the auxiliary module f to switch the working state.

[0085] like Figure 2-17 FIG. 1 is an embodiment of the operating device.

[0086] like Figure 4-6As shown in , 8, the operating mechanism m of the operating device includes a rotating shaft 1, a connecting rod 2 and a driving shaft 4 coaxially rotating around an axis ss, and an energy storage structure 3 respectively connected to the rotating shaft 1 and the connecting rod 2 in a transmission manner; the connecting rod 2 and the driving shaft 4 are synchronously rotated, and the driving shaft 4 is connected to the main contact support 5-0 in a transmission manner to drive the main contact support 5-0 to move along the extension direction of the axial direction ss, that is, while the driving shaft 4 reciprocates around the axis ss, it drives the main contact support 5-0 to reciprocate along the extension direction of the axis ss, thereby closing and disconnecting the active contact mechanism 5 and the main static contact mechanism 6; the The operating device has a closing state (the active contact mechanism 5 and the main static contact mechanism 6 are in a closed state) and an opening state (the active contact mechanism 5 and the main static contact mechanism 6 are in a disconnected state); the rotating shaft 1 has a first position, an intermediate position and a second position sequentially arranged along its rotation direction, that is, the rotating shaft 1 can reach the second position from the first position via the intermediate position or from the second position via the intermediate position to the first position by rotating around the axis ss; the connecting rod 2 has a third position and a fourth position sequentially arranged along its rotation direction, that is, the connecting rod 2 can reach the second position from the first position via the intermediate position by rotating around the axis ss. The third position is rotated to the fourth position or from the fourth position to the third position; the operating device is in the closed state (correspondingly, the switch device is in the closed state and the active contact mechanism 5 is in the closed position and is in the closed state with the main static contact mechanism 6), the shaft 1 is in the first position and the connecting rod 2 is in the third position; the operating device is in the open state (correspondingly, the switch device is in the open state and the active contact mechanism 5 is in the disconnected position and is in the disconnected state with the main static contact mechanism 6), the shaft 1 is in the second position and the connecting rod 2 is in the fourth position; the shaft 1 is subjected to an external force (the external force can be a passive operating force from the operator) Or the driving force of the electric operating mechanism) is driven to rotate from the first position or the second position to the middle position so that the energy storage structure 3 stores energy, and the connecting rod 2 remains stationary during the energy storage process of the energy storage structure 3. When the rotating shaft 1 is in the middle position, the energy storage structure 3 stores energy to the maximum value, that is, the rotating shaft 1 rotates from the first position to the middle position or from the second position to the middle position to store energy, and in the process of the energy storage structure 3 completing the energy storage, the connecting rod 2 remains stationary and does not rotate around the axis ss. When the rotating shaft 1 rotates from the first position or the second position to the middle position, the energy storage process of the energy storage structure 3 ends. Further, when the operating mechanism m is in the closed state, the rotating shaft 1 has a tendency to rotate in the first rotation direction and the connecting rod 2 has a tendency to rotate in the second rotation direction, and the first rotation direction and the second rotation direction are opposite to each other; when the operating mechanism m is in the open state, the rotating shaft 1 has a tendency to rotate in the second rotation direction and the connecting rod 2 has a tendency to rotate in the first rotation direction.

[0087] The operating device of this embodiment has a simple operating mechanism m. When switching between the closed state and the open state, the rotating shaft 1 drives the energy storage structure 3 to store energy first. After the rotating shaft 1 rotates to the middle position, the energy storage structure 3 releases energy and drives the rotating shaft 1 and the connecting rod 2 to rotate relative to each other in opposite directions to respectively realize the switching of the working positions. The moving contact 5-1 and the static contact 6-00 can be quickly disconnected and closed through the main contact support 5-0, eliminating or significantly reducing the possibility of arcing when the moving contact 5-1 and the static contact 6-00 are closed and disconnected. Moreover, compared with the existing method of directly driving the main contact support 5-0 through the rotating shaft 1, the operating mechanism m can significantly increase the rotation angle of the connecting rod within a limited space, thereby increasing the movement of the main contact support 5-0 coordinated with it, increasing the opening distance between the moving contact 5-1 and the static contact 6-00, and having good operating performance. It also makes the structure of the operating mechanism m more compact and smaller in size. Moreover, the connecting rod 2 drives the main contact support 5-0 to move linearly through the driving shaft 4, which is beneficial to reducing the space required for the main contact support 5-0 to move.

[0088] Furthermore, the connecting rod 2 and the driving shaft 4 are of an integrated or split structure.

[0089] Furthermore, the rotation angle of the rotating shaft 1 switching between the first position and the second position is 90°, and the rotation angle of the rotating shaft 1 switching from the first position or the second position to the intermediate position is 70°~80° (preferably 75°); that is, when the rotating shaft 1 rotates from the first position to the second position or from the second position to the first position, the rotating shaft 1 needs to rotate 90°, and when the rotating shaft 1 rotates from the first position or the second position to the intermediate position, the rotating shaft 1 needs to rotate 70°~80° (preferably 75°).

[0090] Further, the rotation angle of the connecting rod 2 switching between the third position and the fourth position is 45° to 90° (preferably 60° to 90°, specifically 60°); that is, when the connecting rod 2 rotates from the third position to the fourth position or from the fourth position to the third position, the connecting rod 2 needs to rotate 45° to 90° (preferably 60° to 90°, specifically 60°). It should be pointed out that the rotation angle of the connecting rod 2 switching between the third position and the fourth position can be adjusted as needed, mainly according to the moving stroke of the active contact mechanism 5, and the maximum rotation angle of the connecting rod 2 does not exceed 90°.

[0091] like Figure 4-6 As shown in FIG. 8 , the energy storage structure 3 includes at least one energy storage spring 3-0, and both ends of the energy storage spring 3-0 are respectively connected to the rotating shaft 1 and the connecting rod 2 in a transmission manner. The energy storage spring 3-0 has a dead point position. The rotating shaft 1 rotates from the first position or the second position to the middle position to make the energy storage spring 3-0 move to the dead point position and store maximum energy, that is, the middle position of the rotating shaft 1 corresponds to the dead point position of the energy storage spring 3-0.

[0092] Further, the energy storage spring 3-0 is a linear compression spring, and when the energy storage spring 3-0 is at the dead point, the geometric axis of the linear compression spring intersects and is coplanar with the axis ss. Further, when the energy storage spring 3-0 is at the dead point, its geometric axis intersects perpendicularly with the axis ss.

[0093] As other embodiments, the energy storage spring 3-0 can also be a torsion spring, which includes a spiral portion and two spring arms respectively connected to the spiral portion, the spiral portion is freely arranged, one spring arm is transmission-connected to the rotating shaft 1, and the other spring arm is transmission-connected to the connecting rod 2; when the torsion spring is at the dead point position, the connection between the torsion spring and the rotating shaft 1, the connection between the torsion spring and the connecting rod 2, and the axis ss are intersecting and coplanar.

[0094] Further, the energy storage structure 3 includes two energy storage springs 3-0, and the two energy storage springs 3-0 are arranged on both radial sides of the rotating shaft 1. Further, the two energy storage springs 3-0 are mutually centrally symmetrical structures with the axis ss as the symmetry center.

Furthermore, the connecting rod bearing portion 2a also includes a first side plate 2-0a and a second side plate 2-1a of the bearing portion which are arranged relatively at an interval, and both ends of the first side plate 2-0a and the second side plate 2-1a of the bearing portion are connected by a bearing portion connecting bridge 2-2a (that is, one end of the first side plate 2-0a and the second side plate 2-1a of the bearing portion are connected by a bearing portion connecting bridge 2-2a and the other end of the first side plate 2-0a and the second side plate 2-1a of the bearing portion are also connected by a bearing portion connecting bridge 2-2a), and the first side plate 2-0a, the second side plate 2-1a and the bearing portion connecting bridge 2-2a are overall frame-type structures; the rotating shaft 1 is rotatably inserted in the middle of the first side plate 2-0a and the middle of the second side plate 2-1a of the bearing portion, and two energy storage springs 3-0 are arranged between the first side plate 2-0 and the second side plate 2-1 of the bearing portion. It should be pointed out that the connecting rod bearing part 2a can only be provided with the first side plate 2-0a of the bearing part or the second side plate 2-1a of the bearing part, but it will affect the structural strength and stability of the connecting rod 2; or, the connecting rod bearing part 2a can only be provided with one bearing part connecting bridge 2-2a, and the operating mechanism m can only be provided with one energy storage spring 3-0, but it will destroy the symmetry of the overall structure of the operating mechanism m and affect the stability and reliability of the operation of the operating mechanism m.

[0126] like Figure 4-6 As shown, when the active contact mechanism 5 and the main static contact mechanism 6 are closed, the active contact mechanism 5 moves along the extension direction of the axis ss toward the side where the upper cover h-1 is located; when the active contact mechanism 5 and the main static contact mechanism 6 are disconnected, the active contact mechanism 5 moves along the extension direction of the axis ss toward the side where the base h-2 is located. Fig.15 and 23As shown, the transmission arm 5-001 supporting the driven part 5-00 is provided with a main rail 5-0010 and a baffle 5-0011, and the baffle 5-0011 is arranged at one end of the main rail 5-0010 and is connected to the main rail 5-0010 by bending; the base h-2 of the main shell h is provided with a main guide groove h-20; the main rail 5-0010 is slidably arranged in the main guide groove h-20; when the switch device is opened (that is, the operating device or operating mechanism m is opened), the baffle 5-0010 abuts against one end of the side wall of the main guide groove h-20 to limit the main contact support 5-0 in the disconnected position, thereby preventing the main contact support 5-0 from directly hitting the bottom wall of the base h-2, thereby extending the service life of the switch device.

[0127] Further, such as Figure 1 and 14 As shown, the main contact support 5-0 is also provided with a switch-on / off indication structure 5-0013; the housing of the operating device also includes an indication window h-10 arranged on its side wall; the switch-on / off indication structure 5-0013 cooperates with the indication window h-10 to indicate the current position of the main contact support 5-0, which is beneficial for the operator to judge the current position of the main contact support 5-0, so as to judge whether the moving contact 5-1 of the moving contact mechanism 5 is disconnected from the static contact 6-00, thereby improving the safety of electricity use. Further, the switch-off indication structure 5-0013 includes a switch-on indicator and a switch-off indicator. When the active contact mechanism 5 is in the closed position (i.e., when the active contact mechanism 5 is closed with the main static contact mechanism 6), the switch-on indicator is visible through the indication window h-10, and when the active contact mechanism 5 is in the disconnected position (i.e., when the active contact mechanism 5 is disconnected with the main static contact mechanism 6), the switch-off indicator is visible through the indication window h-10.

[0128] Specifically, the switch opening and closing indication structure 5-0013 is arranged on the support actuated portion 5-00 of the main contact support 5-0; the indication window h-10 is arranged on the side wall of the main housing h of the switch body z.

Further, the support bearing parts 5-01 and the support driven part 5-00 are an integrated or split structure; in this embodiment, the support bearing parts 5-01 and the support driven part 5-00 are preferably an integrated structure.

[0131] Specifically, the main contact support 5-0 is provided with two or more groups of support bearing parts 5-01, and the number of the support bearing parts 5-01 is adjusted according to the number of phases of the switch device, for example: if the switch device is a single-phase switch, the number of the support bearing parts 5-01 is 1, if the switch device is a two-phase switch, the number of the support bearing parts 5-01 is 2, if the switch device is a three-phase switch, the number of the support bearing parts 5-01 is 3, and if the switch device is a three-phase four-wire switch, the number of the support bearing parts 5-01 is 4. Further, each of the support bearing parts 5-01 is an integrated structure, which is conducive to improving the overall structural strength of the main contact support 5-0.

[0132] As other embodiments, the support passive part 5-00 and the support bearing part 5-01 are split structures, which makes it easy to adjust the number of support bearing parts 5-01 according to actual needs, thereby improving the versatility of the main contact support 5-0, but it also leads to the defect of an increased number of parts.

[0133] like Figure 6 and 8 As shown, a layout of the operating device is shown:

The moving touch plate positioning platform 5-101 and the contact positioning platform 5-013 are plugged and limited to ensure reliable limitation between the moving touch plate 5-10 and the main contact support 5-0, and avoid displacement of the moving contact 5-1 and the static contact 6-00 during the closing and opening process, thereby ensuring working reliability. Furthermore, a supporting spring positioning platform 5-014 is provided on the side wall of the contact socket 5-010 opposite to the contact partition wall 5-011, and the magnetic plate 5-11 is provided with two groups of magnetic plate spring positioning platforms, and the two magnetic plate positioning platforms are arranged opposite to the two magnetic plate limiting holes; the contact spring 5-2 is a linear compression spring, one end of which is sleeved on the corresponding supporting spring positioning platform 5-014, and the other end is clamped between the corresponding two magnetic plate spring positioning platforms.

[0140] As another embodiment, the contact spring 5-2 is a V-shaped spring sheet, two ends of which are respectively pressed against the two ends of the corresponding magnetic conductive plate 5-11 and the middle part is pressed against the side wall of the contact socket 5-010.

[0141] like Figure 18-20 The figure shows an embodiment of the main static contact mechanism 6.

[0142] The main static contact mechanism 6 includes two sets of static contact assemblies 6-0 arranged opposite to each other, each set of static contact assemblies 6-0 includes static contacts 6-00, and the two static contacts 6-00 are respectively used to close and disconnect with the two ends of the moving contact 5-1 of the active contact mechanism 5. Further, in the main static contact mechanism 6, the two static contacts 6-00 have the same structure, which is conducive to reducing the types of parts.

[0143] Specifically, the static contact 6-00 is an L-shaped structure, which includes a static contact blade 6-000 and a static wiring board 6-001, and the static contact blade 6-000 is bent and connected to the static wiring board 6-001 and is an integrated structure. Further, the plane where the static wiring board 6-001 is located is perpendicular to the axis ss, that is, perpendicular to the moving direction of the active contact mechanism 5.

[0144] Furthermore, the static contact assembly 6-0 also includes a terminal block 6-01 used in conjunction with the static terminal board 6-001 of the static contact 6-00. Furthermore, the terminal block 6-01 includes a wiring frame 6-010 and a wiring screw 6-011, the wiring screw 6-011 is threadedly connected to the wiring frame 6-010, and the static terminal board 6-001 is inserted into the wiring frame 6-010; the wiring screw 6-011 is screwed by an external force to drive the wiring frame 6-010 to move along the axis of the wiring screw 6-011 (the axis of the wiring screw 6-011 is preferably coplanar with the axis ss and parallel and spaced apart), and the external wire is pressed between the wiring frame 6-010 and the static terminal board 6-001.

In the arc extinguishing mechanism, since the static contact 6-00 is an L-shaped structure, the electromagnetic force at the bent connection between the static terminal plate 6-001 of the static contact 6-00 and the static contact blade 6-000 drives the arc separated by the static contact 6-00 and the moving contact 5-1 to move into the arc extinguishing chamber 7, ensuring that the arc is completely or mostly extinguished in the arc extinguishing chamber 7, and preventing the arc from moving toward the operating mechanism m.

One end of the auxiliary linkage part f1-000 extends out of the module shell f0 and is used to be connected to the active contact mechanism 5 for transmission and synchronous movement. When the switch device switches between the closing state and the opening state, the active contact mechanism 5 moves between the closed position and the open position, and at the same time drives the auxiliary trigger rod f1-00 to move through the auxiliary linkage part f1-000, so that the auxiliary trigger rod f1-00 triggers the signal output mechanism to change the working state. The transmission mode and structure of the auxiliary module f and the active contact mechanism 5 are simple and reliable, ensuring the reliable operation of the auxiliary module f.
