Description

Technical Field

[0001] This application relates to the field of low-voltage electrical technology, and more specifically, to a quick-closing mechanism and a panel switch. Background Technology

[0002] Panel switches, circuit breakers, and other electrical products used to control the on / off state of circuits typically employ a combination of moving and stationary contacts. The closing speed of these contacts is affected by manual operation; the product may close slowly or incompletely. If the contacts are too close together, causing a breakdown discharge, and the contacts cannot close in time, this can lead to increased contact wear or, in severe cases, safety accidents.

[0003] To improve the closing speed of the moving and stationary contacts, existing technology adds a spring to the moving contact to provide a certain quick-closing force. However, the energy storage of the spring is insufficient, and its effect on improving the movement speed of the moving contact is limited. When a large current surge occurs during a one-button power-off, welding still occurs at the contact surface between the moving and stationary contacts. Utility Model Content

The quick-closing member includes a first abutting portion for abutting against the moving contact and a second abutting portion for abutting against the driving member. The distance between the first abutting portion and the moving contact is less than the distance between the second abutting portion and the driving member. After the driving member rotates in the closing direction and abuts against the second abutting portion, it can drive the quick-closing member to rotate in a preset direction so that the first abutting portion separates from the moving contact.

[0014] Optionally, when the reset member is in the initial state, the first abutting part abuts against the limiting part of the housing to restrict the first abutting part from rotating in a direction opposite to the preset direction.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] Panel switches, circuit breakers, and other electrical products used to control the on / off state of circuits typically employ a combination of moving and stationary contacts to achieve circuit control. Existing technology adds a spring to the moving contact to improve the closing speed of the moving and stationary contacts, providing a certain quick-closing force to accelerate its movement. However, the spring's energy storage is insufficient, limiting its effectiveness in increasing the moving contact's speed. Furthermore, during a single-button power-off event generating a large current surge, welding can still occur at the contact surface between the moving and stationary contacts.

[0033] To address the aforementioned technical problems, one aspect of the embodiments of this application is described below. Figure 1 and Figure 2 A quick-closing mechanism 10 is provided, which is disposed in the housing 20, and can effectively increase the movement speed of the moving contact 12 during closing, so as to realize quick closing between the moving contact 12 and the stationary contact 11.

[0034] The quick-closing mechanism 10 includes: a stationary contact 11 fixed inside the housing 20, a movable contact 12 rotatably disposed inside the housing 20, a quick-closing component 13, and a driving component 14. Please refer to the reference. Figure 3 The moving contact 12 is coaxially arranged with the driving member 14 and connected by the elastic connector 15. When no external force is applied, the driving member 14 can drive the moving contact 12 to move synchronously through the elastic connector 15. When the moving contact 12 is subjected to external force, the driving member 14 and the moving contact 12 can move relative to each other. At this time, the elastic connector 15 deforms and stores energy.

[0035] The quick-closing member 13 is located on the side of the moving contact 12 facing the stationary contact 11. The quick-closing member 13 includes a first abutting portion 131 for abutting against the moving contact 12 and a second abutting portion 132 for abutting against the driving member 14. The first abutting portion 131 and the second abutting portion 132 are interconnected and move synchronously. Please refer to the reference section. Figure 4 The distance between the first abutment portion 131 and the moving contact 12 is less than the distance between the second abutment portion 132 and the driving member 14. After the driving member 14 rotates in the closing direction and abuts against the second abutment portion 132, it can drive the quick-closing member 13 to rotate in a preset direction, so that the first abutment portion 131 separates from the moving contact 12.

[0036] Specifically, the drive member 14 rotates in the closing direction to drive the moving contact 12 to contact the stationary contact 11 for closing. During the rotation in the closing direction, the drive member 14 first drives the moving contact 12 to move synchronously through the elastic connector 15, bringing the moving contact 12 closer to the stationary contact 11. Then, the first abutting part 131 of the quick-closing member 13 abuts against the moving contact 12, and the moving contact 12 no longer moves towards the stationary contact 11. At this time, the drive member 14 continues to rotate, and the elastic connector 15 deforms and stores energy. After the drive member 14 continues to move until it abuts against the second abutting part 132 of the quick-closing member 13, it drives the quick-closing member 13 to rotate in a preset direction, which is the same as or opposite to the closing direction. When the first abutting part 131 of the quick-closing member 13 disengages from the moving contact 12, the moving contact 12 moves rapidly towards the stationary contact 11 under the drive of the elastic connector 15, thereby achieving rapid closing.

[0037] In the aforementioned quick-closing mechanism 10, the moving contact 12 and the driving component 14 are separately configured and connected by an elastic connector 15. Simultaneously, a quick-closing component 13 is added to the side of the moving contact 12 facing the stationary contact 11. The quick-closing component 13 interacts with both the moving contact 12 and the driving component 14, and, in conjunction with the elastic connector 15, achieves rapid closure of the moving contact 12 and the stationary contact 11. The quick-closing mechanism 10 has a simple structure. The quick-closing component 13, in cooperation with the elastic connector 15, provides sufficient quick-closing force to the moving contact 12, effectively increasing the movement speed of the moving contact 12 and thus significantly reducing welding.

[0038] Optionally, the quick-closing mechanism 10 also includes a reset member 16 disposed in the housing 20. One end of the reset member 16 abuts against the housing 20 and the other end abuts against the quick-closing member 13. When the quick-closing member 13 rotates in a preset direction, the reset member 16 deforms and stores energy.

[0039] Before the second contact portion 132 of the quick-closing member 13 abuts against the driving member 14, the reset member 16 is in its initial state. During the process of the driving member 142 driving the quick-closing member 13 to rotate in a preset direction, the reset member 16 deforms due to the rotation of the quick-closing member 13, thereby storing energy. When the moving contact 12 and the stationary contact 11 open, the driving member 142 rotates and resets in the opening direction opposite to the closing direction, releasing the contact with the quick-closing member 13. At this time, the reset member 16 restores its energy, providing a reset force for the quick-closing member 13 to reset.

[0040] Alternatively, please refer to Figure 5 When the reset member 16 is in the initial state, the first abutting part 131 abuts against the limiting part 21 of the housing 20 to restrict the first abutting part 131 from rotating in a direction opposite to the preset direction.

[0041] When the reset member 16 is in the initial state, the quick-closing member 13 is also in the initial state. A limiting part 21 is provided inside the housing 20. By using the limiting part 21 to restrict the first abutting part 131 from rotating in a direction opposite to the preset direction, it can be prevented that after the first abutting part 131 of the quick-closing member 13 abuts against the moving contact 12, the quick-closing member 13 will rotate in a direction opposite to the preset direction under the drive of the moving contact 12, thereby causing the first abutting part 131 to fail to limit the moving contact 12.

[0042] Alternatively, please refer to Figure 4 The center surface 1311 of the first contact portion does not overlap with the rotation axis 134 of the quick-connect member. This allows for a smaller closing force.

[0043] It should be noted that the center plane 1311 of the first abutment portion refers to the plane that symmetrically divides the first abutment portion 131. The rotation axis 134 of the quick-connect component refers to the straight line around which the quick-connect component 13 rotates.

[0044] Optionally, when the end of the first abutting portion 131 abuts against the moving contact 12, the angle θ between the line connecting the abutting point of the moving contact 12 (the point that abuts against the first abutting portion 131) and the rotation axis of the moving contact 12 and the first abutting portion 131 is less than or equal to 90°. This arrangement ensures that the first abutting portion 131 can apply sufficient abutting force to the moving contact 12.

[0045] Alternatively, please refer to Figure 1 and Figure 2 The quick-closing mechanism 10 also includes a first rotating shaft 17, the axis of which is parallel to the rotation axis of the quick-closing member 13. The moving contact 12 and the driving member 14 are both sleeved on the first rotating shaft 17, and both the moving contact 12 and the driving member 14 can rotate relative to the first rotating shaft 17.

[0046] Optionally, one end of the first rotating shaft 17 is fixed by being inserted into a first slot 22 inside the housing 20, and the other end of the first rotating shaft 17 is fixed by being inserted into another first slot 22 inside the housing 20, thereby realizing the rotational connection between the moving contact 12 and the housing 20, and between the driving member 14 and the housing 20.

[0047] The moving contact 12 and the driving component 14 are mounted on the same first rotating shaft 17, which is snapped and fixed to the housing 20. This facilitates the coaxial arrangement of the moving contact 12 and the driving component 14, and also makes it easy to quickly install the moving contact 12 and the driving component 14 into the housing 20.

[0048] Optionally, the first rotating shaft 17 includes a first mounting portion 171, a second mounting portion 172 and a third mounting portion 173 respectively disposed at opposite ends of the first mounting portion 171 and coaxially disposed with the first mounting portion 171; the moving contact 12 includes a first connecting portion 122 and a contact head 123 connected to the first connecting portion 122; the driving member 14 includes a second connecting portion 141 and a driving portion 142 connected to the second connecting portion 141; the elastic connecting member 15 is sleeved on the first mounting portion 171, the first connecting portion 122 is sleeved on the second mounting portion 172, and the second connecting portion 141 is sleeved on the third mounting portion 173.

[0049] The first mounting part 171 is located between the second mounting part 172 and the third mounting part 173. The elastic connector 15 is sleeved on the first mounting part 171. The moving contact 12 is sleeved on the second mounting part 172 through the first connecting part 122 and cooperates with the stationary contact 11 through the contact head 123 to realize opening and closing. The driving member 14 is sleeved on the third mounting part 173 through the second connecting part 141 and abuts against the second abutting part 132 of the quick-closing member 13 through the driving part 142.

[0050] Optionally, the diameter of the first mounting portion 171 is larger than the diameters of the second mounting portion 172 and the third mounting portion 173, so that the two end faces of the first mounting portion 171 can respectively limit the moving contact 12 and the driving member 14.

[0051] Optionally, the second mounting part 172 extends from the end of the first connecting part 122 and is inserted into a first slot 22 of the housing 20, and the third mounting part 173 extends from the end of the second connecting part 141 and can be inserted into another slot of the housing 20.

[0052] Optionally, one end of the first connecting portion 122 of the moving contact 12 abuts against the first mounting portion 171 and the other end abuts against the housing 20, and one end of the second connecting portion 141 of the driving member 14 abuts against the first mounting portion 171 and the other end abuts against the housing 20. In this way, the moving contact 12 and the driving member 14 can be prevented from moving along the axial direction of the first rotating shaft 17 within the housing 20.

[0053] Optionally, the elastic connector 15 is a spring, which is sleeved on the first rotating shaft 17. The moving contact 12 is provided with a first connecting hole 124, and the driving member 14 is provided with a second connecting hole 143. The two ends of the spring are respectively inserted into the first connecting hole 124 and the second connecting hole 143.

[0054] The two ends of the spring are fixed to the moving contact 12 and the driving member 14, respectively. Under normal conditions, the driving member 14 can drive the moving contact 12 to move synchronously via the elastic connector 15. However, the spring is elastic, and under external force, the relative positions of its two ends will change. Therefore, after the moving contact 12 is held in place by the first abutting part 131 of the quick-closing member 13, the driving member 14 and the moving contact 12 can rotate relative to each other. During this relative rotation, the spring deforms under force, storing energy. After the first abutting part 131 disengages from the moving contact 12, the spring recovers and releases energy, driving the moving contact 12 to move rapidly towards the stationary contact 11, thereby achieving rapid closing.

[0055] The spring is low in cost and easy to install. As an elastic connector 15 between the moving contact 12 and the drive member 14, it can reduce the cost of the quick-closing mechanism 10 and improve the assembly efficiency of the quick-closing mechanism 10.

[0056] Optionally, the quick-closing mechanism 10 further includes a second rotating shaft 18, the axis of which is parallel to the rotation axes of the moving contact 12 and the driving member 14. The quick-closing member 13 further includes a third connecting portion 133, which is connected to the first abutting portion 131 and the second abutting portion 132 respectively, and is sleeved on the second rotating shaft 18. The quick-closing member 13, sleeved on the second rotating shaft 18 via the third connecting portion 133, is rotatable relative to the second rotating shaft 18.

[0057] Optionally, one end of the second rotating shaft 18 is fixed by being inserted into a second slot 23 inside the housing 20, and the other end of the second rotating shaft 18 is fixed by being inserted into another second slot 23 inside the housing 20, thereby realizing the rotational connection between the quick-connect component 13 and the housing 20.

[0058] Optionally, the reset component 16 is a torsion spring, which is sleeved on the second rotating shaft 18. One end of the torsion spring abuts against the housing 20, and the other end of the torsion spring is bent and hooks onto the first abutment part 131 or the second abutment part 132, thereby achieving abutment with the quick-connect component 13. Using a torsion spring to reset the quick-connect component 13 is low-cost and easy to implement.

[0059] Please refer to Figure 6 and Figure 7 This embodiment also provides a panel switch 30, including a quick-closing mechanism 10 as described above.

[0060] The panel switch 30 includes the same structure and beneficial effects as the quick-closing mechanism 10 in the foregoing embodiments. The structure and beneficial effects of the quick-closing mechanism 10 have been described in detail in the foregoing embodiments and will not be repeated here.

[0061] Optionally, the housing 20 includes a rear seat 24 and a cover plate 25 detachably connected to the rear seat 24. The quick-closing mechanism 10 is installed inside the rear seat 24, positioned between the cover plate 25 and the rear seat 24. The housing 20 is configured as two detachable parts, facilitating the installation and maintenance of the quick-closing mechanism 10.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
