Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to an electric pressure plate. Background Technology

[0002] Pressure plates are typically installed in the secondary circuits of protection devices, measurement and control devices, etc. They connect or disconnect the circuit mechanically to enable or disable the corresponding protection or automation functions.

[0003] like Figure 1 As shown, the pressure plate 1 typically includes a base 2 and two insulating tubes 6 connected to both ends of the base 2. Conductive posts 4 are inserted into the two insulating tubes 6. One of the conductive posts 4 is pivotally connected to a conductive swing arm 3. When the conductive swing arm 3 is pushed and pivoted to engage with the other conductive post 4, the pressure plate 1 switches to the closed position, connecting the circuit, and the corresponding function of the circuit is in normal working condition. A clamping nut 5 is provided at the upper end of the conductive post 4, which can be used to clamp the conductive swing arm 3. When the conductive swing arm 3 is pushed and pivoted to separate from the other conductive post 4, the pressure plate 1 switches to the open position, cutting off the circuit, and the corresponding function of the circuit no longer functions.

[0004] Existing pressure plates typically rely on manual operation of the conductive swing arm 3. After rotating the swing arm to the closed position, a tightening nut is needed to secure it, ensuring a secure electrical closure. Conversely, to open the pressure plate, the tightening nut must be loosened before rotating the swing arm. This process is complex, labor-intensive, and inefficient. Furthermore, it is prone to omissions or errors, which can lead to malfunctions or failures to activate the protection device, causing safety accidents. While electric pressure plates have emerged in recent years, their large size necessitates significant installation space. Utility Model Content

[0009] In one embodiment, a cover plate is provided on the top of the main body. The cover plate has a motor shaft hole in the middle for the motor shaft to pass through. The cover plate has guide post holes on both sides of the motor shaft hole for the contact guide post to pass through.

[0010] In one embodiment, the electric operating mechanism includes a motor and a conductive rotating plate. The motor is installed in the inner cavity of the main body and is located between the two conductive connectors.

[0011] In one embodiment, the inner cavity of the main body is further provided with an isolation sidewall, which extends upward from the bottom plate of the main body and is used to isolate the motor from the two conductive connectors.

[0012] In one embodiment, the rotating shaft of the motor is connected to the middle of the conductive rotating plate, and the motor can drive the conductive rotating plate to rotate, so that the two ends of the conductive rotating plate are respectively engaged or separated from the two contact guide posts, so that the two contact guide posts are connected or disconnected.

Detailed Implementation

[0018] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figures 1-10 As shown, this embodiment provides an electric pressure plate 10, including a main body 11, as shown in the figure. Figure 3 , Figure 4 as well as Figure 6 The main body 11 includes a base plate 116 and side plates 114 surrounding it. The side plates 114 and the base plate 116 together form a cavity structure with an upper opening. The main body 11 is configured to be mounted on the base 2 of the pressure plate 1 and positioned between two insulating tubes 6. The electric pressure plate 10 also includes conductive connectors 12. Two conductive connectors 12 are provided and installed on opposite sides of the main body 11. The conductive connectors 12 are used to be installed with the conductive posts 4 and the clamping nuts 5 to achieve electrical connection. The electric pressure plate 10 also includes an electric operating mechanism, which is used to make or break the connection between the two conductive connectors 12, thereby making or breaking the connection between the two conductive posts 4. This electric pressure plate 10 can be directly installed on an existing pressure plate without changing the structure of the existing pressure plate. It has good compatibility, greatly simplifies the installation process, and improves installation efficiency. Moreover, the main body 11 is positioned between two insulating tubes 6, which greatly reduces the overall size of the electric pressure plate 10, occupies less installation space, and makes the equipment more compact.

[0021] The conductive connector 12 includes a first connecting portion 121, a second connecting portion 122, and a contact guide post 123. The first connecting portion 121 and the second connecting portion 122 are connected in an L-shape. The contact guide post 123 is perpendicularly connected to the surface of the first connecting portion 121, and the contact guide post 123 and the second connecting portion 122 are located on opposite sides of the first connecting portion 121, respectively. The first connecting portion 121 is provided with a connecting hole 124, which is suitable for being fitted onto the conductive post 4, and tightening the clamping nut 5 can clamp the first connecting portion 121. The second connecting portion 122 of the conductive connector 12 is installed in the inner cavity 113 of the main body 11 with its free end facing downward. Therefore, when the first connecting portion 121 of the conductive connector 12 is clamped by the clamping nut 5, the contact guide post 123 of the conductive connector 12 is oriented upward. There are two conductive connectors 12, and the first connecting portions 121 of the two conductive connectors 12 are respectively installed and connected to the two conductive posts 4.

[0022] The electric operating mechanism includes a motor 13 and a conductive rotating plate 15. The motor 13 is installed in the inner cavity of the main body 11 and is located between two conductive connectors 12. The inner cavity of the main body 11 is also provided with an isolation sidewall 117, which extends upward from the bottom plate 116 of the main body 11. The isolation sidewall 117 is used to isolate the motor 13 from the two conductive connectors 12 to improve the safety of the equipment.

[0023] The rotating shaft of the motor 13 is connected to the middle of the conductive rotating plate 15. The conductive rotating plate 15 contains conductive material. The motor 13 can drive the conductive rotating plate 15 to rotate, so that the two ends of the conductive rotating plate 15 are respectively engaged or disengaged from the two contact guide posts 123, making the two contact guide posts 123 conductive or disconnected, thereby making the circuit conductive or disconnected.

[0024] The upper end of the side plate 114 of the main body 11 is provided with two opposing notches 115, which are used to snap on and install the conductive connector 12, thereby forming a stable connection between the conductive connector 12 and the main body 11. Furthermore, the upper surface of the first connecting part 121 is flush with the upper end of the side plate 114. Thus, a cover plate 14 can be placed on top of the main body 11. The cover plate 14 can increase the electrical isolation performance between the motor 13 and the conductive rotating plate 15, improving safety. A motor shaft hole 141 is provided in the middle of the cover plate 14, through which the rotating shaft of the motor 13 passes to connect with the middle of the conductive rotating plate 15. Guide post holes 142 are provided on both sides of the motor shaft hole 141, for the contact guide post 123 to pass through.

[0025] The conductive rotating plate 15 includes hook-shaped structures 152 at both ends, and is non-rotatably fitted onto the rotating shaft of the motor 13. In this embodiment, the central hole 151 of the conductive rotating plate 15 is D-shaped, and the cross-section of the rotating shaft of the motor 13 is also D-shaped, thereby achieving a non-rotatable fit between the conductive rotating plate 15 and the rotating shaft of the motor 13. To improve the electrical isolation performance between the conductive rotating plate 15 and the motor 12, in some other embodiments, the rotating shaft of the motor can also be connected to the middle of the conductive rotating plate through an insulating insulating ring.

[0026] A top cover 16 is installed above the main body 11, covering the outer perimeter of the conductive rotating piece 15, thus protecting the conductive rotating piece 15 and enhancing safety. The top cover 16 also has two viewing notches 161, located diagonally opposite each other. These notches allow for easy observation of the engagement or disengagement status of the conductive rotating piece 15 with the contact post 123, as shown below. Figure 2 and Figure 8As shown, this allows for a direct observation of whether the pressure plate is in place, providing a convenient and reliable way to obtain the pressure plate's status.

[0027] Reference Figure 5 The bottom of the main body 11 has two downward protruding positioning ribs 111, which allows the base 2 of the pressure plate 1 to be positioned between the two positioning ribs 111, thus making the installation of the main body 11 on the base 2 more stable; further, the two conductive connectors 12 are pressed into the clamping nut 5, so that the electric pressure plate 10 forms an integral and stable connection structure.

[0028] When motor 13 receives a request to control the engagement of the pressure plate, its rotating shaft rotates in the first direction, simultaneously driving the conductive rotating plate 15 to rotate in the first direction. When the conductive rotating plate 15 reaches its designated position, it establishes electrical connection between the two contact guide posts 123. The two contact guide posts 123 are in contact with and electrically connected to the two conductive posts 4, thus the electrical connection between the two contact guide posts 123 also establishes electrical connection between the two conductive posts 4, causing the pressure plate to switch to the closed position and completing the circuit.

[0029] When motor 13 receives a request to control the pressure plate to retract, the rotating shaft of motor 13 rotates in a second direction opposite to the first direction. Simultaneously, the rotating shaft of motor 13 drives the conductive rotating plate 15 to rotate in the second direction. When the conductive rotating plate 15 reaches its designated position, it disengages from the two contact guide posts 123, thus disconnecting the two conductive posts 4. The pressure plate then switches to the disconnected position, cutting off the circuit. This electric pressure plate 10 is simple to install and operate, and occupies little installation space.

[0030] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
