Description

Technical Field

[0001] This application relates to the field of grounding component technology, and more specifically, to a grounding connection component for a compressor grounding wire. Background Technology

[0002] In the electrical safety system of a compressor, the grounding connection component of the grounding wire is a key part to ensure the safety of equipment and personnel. Its main function is to reliably connect the compressor casing, metal parts and other potentially live parts to the ground to prevent electric shock accidents and equipment damage.

[0003] In related technologies, to enhance the management capabilities for the inspection and maintenance of multiple grounding wires in the later stages, for example, the prior art patent with publication number CN222483716U provides a compressor grounding component. This grounding component installs a grounding box and a ceramic plate on one end of a grounding metal rod, and uses a grounding plate and a nut to fix it to the grounding metal rod and the ceramic plate, so that eight O-type grounding wires can be installed on the grounding box. Compressors in the same area can be centrally connected to the same grounding box. The construction and installation of the grounding metal rod is relatively simple, and centralized grounding is conducive to later inspection and maintenance, improving the management capabilities for multiple grounding wires, thereby reducing the labor intensity of maintenance.

[0004] While the existing technical solutions described above have solved the problem of needing to install multiple sets of grounding wires to connect multiple compressors, which reduces the ability to manage multiple sets of grounding wires during later inspection and maintenance, the following issues remain: when a compressor grounding wire needs maintenance, the box cover must be opened to perform maintenance, and other wiring parts are also exposed. When using metal tools for repair, if the metal tools touch the phase and neutral wires or the phase and grounding body of other workstations, it will cause a short circuit, causing the workstation or related circuits to trip, or even burn out wiring components (such as terminals and cable insulation).

[0005] In view of this, we propose a grounding connection component for the compressor grounding wire. Utility Model Content

[0006] The purpose of this application is to provide a grounding connection component for a compressor grounding wire, which can effectively solve the problem in the prior art that when the wiring component of a certain workstation is repaired, other workstations are also exposed, which can easily lead to tripping of other workstations, and achieve the effect of repairing a single workstation.

[0007] This application provides a grounding connection assembly for a compressor grounding wire, including:

[0008] Junction box;

[0009] The cover, driven to rotate by external force, is located inside the junction box.

[0010] The wiring assembly is fixedly installed inside the junction box and is used to connect the O-type grounding wire;

[0011] The junction box has a rotating groove on the inner side corresponding to the cover, a maintenance slot on the top of the cover, and a rotating assembly on the top of the cover. The rotating assembly includes a baffle plate and is driven by external force to switch the maintenance slot on and off.

[0012] As an optional solution to the technical solution of this application, the wiring assembly includes a ceramic disc, which is fixedly disposed inside the junction box. A connection slot is provided on the top of the ceramic disc, and a wire piece is fixedly disposed inside the connection slot. The wire pieces are arranged in a circular array with connection stations. A connection stud is fixedly disposed on the top of the connection station, and a metal grounding post is fixedly disposed on the bottom of the wire piece. The metal grounding post extends to the bottom through the connection slot and the junction box.

[0013] As an optional solution to the technical solution of this application, the rotating component further includes a fixed column, which is fixedly disposed inside the box cover. A baffle plate is coaxially rotatably connected to the outside of the fixed column. A fixed frame is fixedly disposed on the top of the baffle plate, and a driving component is slidably connected to the top of the fixed frame for driving the baffle plate to rotate.

[0014] As an optional solution to the technical solution of this application, the driving component includes a limiting groove, which is opened on the top of the fixed frame. A limiting disc column is slidably arranged inside the limiting groove. A handle is fixedly arranged on the top of the limiting disc column. A fixing block column is fixedly arranged at the bottom of the handle away from the limiting disc column. The fixing block column is slidably arranged inside the fixing groove through a sliding groove. The fixing groove is opened on the top of the fixing column. The sliding groove is opened at the end of the fixed frame, corresponding to the fixing groove, and located on the side away from the limiting groove.

[0015] As an optional solution to the technical solution of this application, a through groove is provided on the inner side of the junction box corresponding to the connection position, an isolation box is fixedly provided on the outer side of the through groove, a rubber gasket is fixedly provided on the inner side of the isolation box, and an O-type grounding wire is slidably connected on the inner side of the rubber gasket.

[0016] As an optional solution to the technical solution of this application, the inner ring of the end of the O-type grounding wire is slidably disposed on the outside of the connecting stud, and a fixing nut is threaded on the outside of the connecting stud for fixing the O-type grounding wire.

[0017] As an optional solution to the technical solution of this application, the fixed square column protrusion and the fixed groove are square in shape, which are used to fix the baffle after rotation.

[0018] As an optional solution to the technical solution in this application, the bottom of the metal grounding post is connected to the grounding body to guide the grounding current.

[0019] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0020] (1) This application uses a junction box, a cover, wiring components, a maintenance slot and a shield. By rotating the cover, the maintenance slot is rotated to the corresponding grounding wire connection position, and the shield is rotated to open the maintenance slot, so that a single maintenance operation can be carried out on a certain position. This avoids the metal pipes from affecting other grounding wires during maintenance. Therefore, it effectively solves the problem that when the wiring components of a certain position are maintained, other positions are also exposed, which may cause other positions to trip. This achieves the effect of maintaining a single position.

[0021] (2) In this application, when maintenance is required, the handle can be manually operated to directly drive the cover and the baffle to rotate through the fixed block column and the limit plate column. When the baffle is rotated to the maintenance position, the handle is pulled up to disengage the bottom protrusion of the fixed block column from the fixed groove. At this time, the handle can be rotated to drive the baffle to rotate independently through the fixed frame, thereby opening the maintenance slot. When the baffle is rotated to the specified degree, the handle is released to allow the protrusion to re-insert into the fixed groove, thus fixing the baffle and preventing it from being shaken and rotating on its own to block the maintenance slot. After maintenance is completed, the operation is repeated to close the maintenance slot. Attached Figure Description

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 - Figure 4 This application discloses a grounding connection assembly for a compressor grounding wire, including a junction box 1, a cover 2, a wiring assembly 3, a maintenance slot 21, and a baffle plate 43. The cover 2 is rotated and disposed inside the junction box 1 by an external force. The wiring assembly 3 is fixedly disposed inside the junction box 1 and is used to connect an O-type grounding wire 100. A rotating groove 12 is provided on the inside of the junction box 1 corresponding to the cover 2. A maintenance slot 21 is provided on the top of the cover 2. A rotating assembly 4 is provided on the top of the cover 2. The rotating assembly 4 includes a baffle plate 43 and is driven by an external force to open and close the maintenance slot 21.

[0030] After the grounding connection assembly is connected to the ground, the O-type grounding wire 100 can be passed through the corresponding through slot, and then the insertion end can be connected to the wiring assembly 3. At this time, the upper part of the corresponding connection point is in the open state, which facilitates connection and installation. At the same time, the other end of the O-type grounding wire 100 is fixedly connected to the outside of the compressor. When a certain grounding wire needs to be inspected after a period of use, the cover 2 is rotated to make the rotating assembly 4 above the corresponding inspection position. Then, the shield 43 is rotated to open the maintenance slot 21. The grounding wire at the current position can be inspected through the maintenance slot 21 with metal tools, avoiding the impact on the grounding wires of other work positions when using metal tools. This achieves the effect of inspecting a certain work position separately. After the inspection is completed, the shield 43 is reset and the maintenance slot 21 is closed.

[0031] Reference Figure 2 and Figure 4The wiring assembly 3 includes a ceramic disc 31, which is fixedly installed inside the junction box 1. A connecting slot 32 is provided on the top of the ceramic disc 31. A conductor piece 33 is fixedly installed inside the connecting slot 32. The conductor pieces 33 are arranged in a circular array with connecting stations. A connecting stud 34 is fixedly installed on the top of the connecting station. A metal grounding post 36 is fixedly installed at the bottom of the conductor piece 33. The metal grounding post 36 extends to the bottom through the connecting slot 32 and the junction box 1. The inner ring of the end of the O-type grounding wire 100 is slidably installed on the outside of the connecting stud 34. A fixing nut 35 is threaded on the outside of the connecting stud 34 to fix the O-type grounding wire 100. The bottom of the metal grounding post 36 is connected to the grounding body to guide the grounding current.

[0032] First, connect the metal grounding post 36 to the grounding body. Then, insert the O-type grounding wire 100 into the junction box 1 through the rubber gasket 14, and then put its end on the corresponding connecting stud 34. Then, fix the O-type grounding wire 100 by tightening the fixing nut 35. Then, fix the other end of the O-type grounding wire 100 to the outside of the compressor. When the O-type grounding wire 100 is inserted into the junction box 1, the middle part of the O-type grounding wire 100 is limited and fixed by the connecting slot 32. At the same time, the rubber gasket 14 binds the O-type grounding wire 100, reducing the impact of compressor shaking on the connection of the O-type grounding wire 100, and sealing the through slot to reduce the impact of water vapor entering the connection.

[0033] Reference Figure 2 and Figure 3 The rotating assembly 4 also includes a fixing post 41, which is fixedly installed inside the cover 2. A baffle plate 43 is coaxially rotatably connected to the outside of the fixing post 41. A fixing frame 44 is fixedly installed on the top of the baffle plate 43. A driving assembly is slidably connected to the top of the fixing frame 44 to drive the baffle plate 43 to rotate. The driving assembly includes a limiting groove 45, which is opened on the top of the fixing frame 44. A limiting disc post 46 is slidably installed inside the limiting groove 45. A handle 49 is fixedly installed on the top of the limiting disc post 46. A fixing block post 48 is fixedly installed at the bottom of the handle 49 away from the limiting disc post 46. The fixing block post 48 is slidably installed inside the fixing groove 42 through the sliding groove 47. The fixing groove 42 is opened on the top of the fixing post 41. The sliding groove 47 is opened at the end of the fixing frame 44 corresponding to the fixing groove 42, located on the side away from the limiting groove 45. The protrusion of the fixing block post 48 and the fixing groove 42 are square, which is used to fix the baffle plate 43 after rotation.

[0034] When maintenance is required, the handle 49 can be manually operated to directly rotate the cover 2 and the baffle 43 via the fixed block post 48 and the limiting plate post 46. When rotated to the maintenance position, the handle 49 is pulled up to disengage the bottom protrusion of the fixed block post 48 from the fixing groove 42. At this time, the handle 49 is rotated again to drive the baffle 43 to rotate independently via the fixing bracket 44, thereby opening the maintenance slot 21. When rotated 90 degrees, the handle 49 is released to allow the protrusion to re-insert into the fixing groove 42, thus fixing the baffle 43 to prevent it from rotating due to shaking and blocking the maintenance slot 21. After maintenance is completed, the operation is repeated to close the maintenance slot 21.

[0035] In summary, when using the compressor grounding connection assembly disclosed in this application, after the grounding connection assembly is connected to the ground, the O-type grounding wire 100 can be passed through the corresponding through slot, and then the insertion end can be connected to the wiring assembly 3. At this time, the upper part of the corresponding connection point is in an open state, which facilitates connection and installation. At the same time, the other end of the O-type grounding wire 100 is fixedly connected to the outside of the compressor. When a certain grounding wire needs to be inspected after a period of use, the cover 2 is rotated to position the rotating assembly 4 above the corresponding inspection position, and then the baffle plate 43 is rotated to open the inspection position. Repair slot 21 is opened, allowing for the inspection and maintenance of the grounding wire at the current location using metal tools. This avoids affecting the grounding wires of other workstations when using metal tools, enabling individual inspection and maintenance of a specific workstation. After inspection and maintenance, the shield 43 is reset, and the repair slot 21 is closed. First, the metal grounding post 36 is connected to the grounding body. Then, the O-type grounding wire 100 is inserted into the junction box 1 through the rubber gasket 14, and its end is fitted onto the corresponding connecting stud 34. Finally, the O-type grounding wire is secured by tightening the fixing nut 35. 100 is fixed in place, and then the other end of the O-type grounding wire 100 is fixedly connected to the outside of the compressor. When the O-type grounding wire 100 is inserted into the junction box 1, the middle of the O-type grounding wire 100 is limited and fixed by the connecting slot 32. At the same time, the rubber gasket 14 restrains the O-type grounding wire 100, reducing the impact of compressor shaking on the connection of the O-type grounding wire 100, and sealing the through slot to reduce the impact of water vapor entering the connection. When maintenance is required, the handle 49 can be directly driven by the fixed block post 48 and the limiting plate post 46. The cover 2 and the baffle 43 are rotated. When the cover is rotated to the maintenance position, the handle 49 is pulled up to disengage the bottom protrusion of the fixed block post 48 from the fixed groove 42. Then, the handle 49 is rotated to drive the baffle 43 to rotate independently through the fixed bracket 44, thereby opening the maintenance slot 21. When the cover is rotated 90 degrees, the handle 49 is released to allow the protrusion to re-insert into the fixed groove 42. The baffle 43 is then fixed to prevent it from rotating due to shaking and blocking the maintenance slot 21. After the maintenance is completed, the operation is repeated to close the maintenance slot 21.
