Description

Technical Field

[0001] This utility model relates to the field of electrical equipment protection technology, and in particular to a rotary folding protective cover for inverter terminals. Background Technology

[0002] Inverter terminals are interface components used to connect external circuits such as power supply, motor, and control signals. They generally include main circuit terminals (such as input power supply terminals and output motor terminals) and control circuit terminals (such as start / stop signal and frequency setting signal terminals). They are the key parts for realizing the electrical connection between the inverter and external equipment.

[0003] The inverter terminal block rotating folding protective cover is a protective device installed above the terminal block that can rotate and fold around a fixed axis to prevent electric shock, dust intrusion, and contact with foreign objects. The cover is connected to the inverter housing via a rotating shaft. During operation, the cover is rotated to open or close. The folding structure allows the cover to fit snugly against the housing or be flipped to a specific angle when folded up, without occupying extra space, thus achieving flexible protection and convenient operation of the terminals.

[0004] In existing technologies, some inverter terminal rotating folding protective covers have significant shortcomings in the traditional wiring fixing methods in the inverter terminal area. When using disposable bundling tools such as cable ties, it is difficult to accurately adjust the tightness of the wiring. Over-bundling can damage the insulation layer of the wires, while loose bundling can easily cause the wires to loosen due to equipment vibration, resulting in poor contact or even short circuits and other safety hazards. Therefore, the inverter terminal rotating folding protective cover is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rotating and folding protective cover for inverter terminals, which aims to improve the problem of wire insulation damage in the prior art, where excessive looseness can easily cause loose wiring and poor contact due to equipment vibration.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rotary folding protective cover for inverter terminals includes a housing. A fixing block is fixedly connected to the right side of the housing. A knob is rotatably connected to the front side of the fixing block. A driven plate is fixedly connected to the rear side of the knob. A driven rod is rotatably connected to the rear side of the driven plate. A driven groove is opened inside the fixing block. Multiple springs are fixedly connected to the left inner wall of the driven groove. A driven plate is fixedly connected to the right side of the multiple springs. Two limiting posts are fixedly connected to the right side of the driven plate. A through groove is opened inside the fixing block. A strap is rotatably connected to the top of the fixing block. Multiple limiting holes are opened inside the strap. A portable component for easy protection of the terminals is opened inside the housing.

[0008] As a further description of the above technical solution:

[0009] The portable component includes a protective groove, a plurality of springs are fixedly connected to the rear inner wall of the protective groove, and a folding plate is fixedly connected to the front side of the plurality of springs.

[0010] As a further description of the above technical solution:

[0011] The bottom of the folding plate is rotatably connected to a rotating plate, and connecting columns are fixedly connected to the left and right sides of the rotating plate respectively.

[0012] As a further description of the above technical solution:

[0013] The driven plate is slidably connected to the inside of the driven groove, and the right side of the driven rod is rotatably connected to the left side of the driven plate;

[0014] As a further description of the above technical solution:

[0015] The outer side of the limiting post is in contact with the inner wall of the limiting hole, and the outer side of the strap is slidably connected to the inside of the through groove.

[0016] As a further description of the above technical solution:

[0017] The outer side of the connecting column is in contact with the inner wall of the housing, and the outer side of the folding plate is slidably connected to the inside of the protective groove;

[0018] As a further description of the above technical solution:

[0019] The housing has an internal connection port, and a display screen is fixedly connected to the top of the housing;

[0020] As a further description of the above technical solution:

[0021] The top of the housing is provided with multiple buttons, and the exterior of the protective groove is formed inside the housing.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, rotating the knob drives the driven plate to rotate synchronously, and then the driven rod on the back of the driven plate pushes the driven plate to slide to the left in the driven groove. While compressing the first spring, the limiting post disengages from the limiting hole of the cable tie, releasing the cable tie from its fixed state. The elastic force of the first spring pushes the driven plate to move to the right, causing the limiting post to re-engage in the limiting hole. The cable tie is fixed by the cooperation between the limiting post and the limiting hole. Thus, the cable tie can be released by rotating the knob to drive the driven structure, and the tightness of the cable tie can be flexibly adjusted to meet different cable tie management needs. The cable tie is automatically locked by the cooperation of the elastic force of the spring and the limiting structure, achieving rapid cable fixation and improving the efficiency and reliability of wiring management.

[0024] 2. In this utility model, the folding plate is unfolded forward from the protective groove by pulling the rotating plate outward. Then, the connecting post at the bottom of the rotating plate is locked into the inner wall of the housing for positioning. At the same time, the second spring is stretched to keep the folding plate in the unfolded state. The unfolded folding plate and the rotating plate form a protective structure. Pulling out the rotating plate causes the folding plate to retract into the protective groove. The elastic force of the second spring causes the folding plate to reset. Thus, by pulling the rotating plate, the folding plate can be unfolded to quickly cover the wiring terminals, effectively prevent dust and foreign objects, and ensure the stable operation of the frequency converter. When not in use, the spring drives the folding plate to automatically reset and store. The structure is compact and flexible, taking into account both protection and ease of operation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a rotary folding protective cover for inverter terminals, comprising a housing 1, which provides installation space for internal devices. A fixing block 2 is fixedly connected to the right side of the housing 1, providing installation space for internal wiring assemblies. A knob 3 is rotatably connected to the front side of the fixing block 2, allowing the operator to rotate the driven plate 4 attached to the knob 3. The driven plate 4 is fixedly connected to the rear side of the knob 3, which in turn drives a driven rod 5 to move synchronously. The driven rod 5 is rotatably connected to the rear side of the driven plate 4, which drives a driven plate 8 to slide synchronously, compressing a spring 7 and causing a limiting post 9 to disengage from the limiting hole 12.

[0033] The fixed block 2 has a driven groove 6 inside, which provides fixation and support for the spring 7. Multiple springs 7 are fixedly connected to the left inner wall of the driven groove 6. These springs 7 have elasticity, providing elastic support to the driven plate 8. The driven plate 8 is fixedly connected to the right side of the multiple springs 7. The driven plate 8 slides under the force of the driven rod 5, compressing the springs 7 and simultaneously causing the limiting post 9 to disengage from the limiting hole 12, thus enabling the wiring to be organized. Two limiting posts are fixedly connected to the right side of the driven plate 8. Position post 9 is used to lock into the interior of the limiting hole 12 to limit and fix the strap 11. The inside of the fixing block 2 is provided with a through groove 10 for the passage of the strap 11. The top of the fixing block 2 is rotatably connected to the strap 11. The strap 11 can organize and fix the wires connected to the inverter terminal. The inside of the strap 11 is provided with multiple limiting holes 12. The limiting holes 12 cooperate with the limiting post 9 to limit and fix the strap 11. The inside of the housing 1 is provided with a portable component for easy protection of the terminal.

[0034] Reference Figure 3 and Figure 4The portable component includes a protective groove 13, which provides fixation and support for spring 14. Multiple springs 14 are fixedly connected to the inner rear wall of the protective groove 13. Springs 14 have elasticity and provide elastic support for the folding plate 15. Folding plates 15 are fixedly connected to the front of multiple springs 14. Folding plates 15 can support rotating plates 16 and can be adapted to different connector terminals for shielding and protection based on their folding characteristics and the elasticity of springs 14. Rotating plates 16 are rotatably connected to the bottom of folding plates 15. Rotating plates 16 provide fixation and support for connecting posts 17. Connecting posts 17 are fixedly connected to the left and right sides of rotating plates 16 respectively. By pulling rotating plates 16, operators can unfold folding plates 15 and stretch springs 14, thereby protecting the connector terminals below and preventing dust from entering the connector terminals.

[0035] Reference Figures 1 to 3 The driven plate 8 is slidably connected to the driven groove 6, which provides limiting and guiding functions for the driven plate 8. The right side of the driven rod 5 is rotatably connected to the left side of the driven plate 8, and the driven plate 8 slides under the force from the driven rod 5. The outer side of the limiting post 9 contacts the inner wall of the limiting hole 12, and the limiting post 9 can cooperate with the limiting hole 12 to limit and fix the strap 11. The outer side of the strap 11 is slidably connected to the inside of the through groove 10, which provides limiting and guiding functions for the strap 11. The outer side of the connecting post 17 contacts the inner wall of the housing 1.

[0036] The connecting post 17 is used to engage with the inner wall of the housing 1, thereby limiting and fixing the folding plate 15, and thus fixing the lower terminal block. The folding plate 15 is externally slidably connected to the inside of the protective groove 13, which provides limiting and guiding functions for the folding plate 15. A connection port 18 is provided inside the housing 1 for connecting external devices to power the frequency converter. A display screen 19 is fixedly connected to the top of the housing 1, displaying real-time monitoring data of the frequency converter. Multiple buttons 20 are provided on the top of the housing 1 for easy operation and control. The protective groove 13 is externally located inside the housing 1, with the housing 1 providing space for its opening.

[0037] Working principle: When it is necessary to organize the inverter circuit, turn the knob 3 to drive the driven plate 4 to rotate synchronously. Then, the driven rod 5 on the back of the driven plate 4 pushes the driven plate 8 to slide to the left in the driven groove 6. While compressing the spring 7, the limiting post 9 disengages from the limiting hole 12 of the strap 11, releasing the fixed state of the strap 11. At this time, the tightness of the strap 11 binding the inverter terminal circuit can be adjusted. After adjustment, release the knob 3. The elastic force of the spring 7 pushes the driven plate 8 to the right, causing the limiting post 9 to re-engage in the limiting hole 12. The cooperation between the limiting post 9 and the limiting hole 12 completes the fixation of the strap 11, achieving the purpose of organizing and fixing the circuit.

[0038] When protection of the terminal block is required, the rotating plate 16 is pulled outward to unfold the folding plate 15 from the protective groove 13. The folding plate 15 is then positioned by the connecting post 17 at the bottom of the rotating plate 16, which engages with the inner wall of the housing 1. At the same time, the second spring 14 is stretched to keep the folding plate 15 unfolded. The unfolded folding plate 15 and the rotating plate 16 form a protective structure that covers the terminal block, preventing dust and foreign objects from contacting the terminal. When protection is not required, the rotating plate 16 is pulled out to retract the folding plate 15 into the protective groove 13. The elastic force of the second spring 14 causes the folding plate 15 to return to its original position. Through the folding characteristics of the folding plate 15 and the elastic support of the second spring 14, the protection requirements of different terminal blocks can be adapted to achieve flexible shielding and convenient storage.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
