Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a one-to-one terminal block with a protective cover. Background Technology

[0002] As high-power electrical equipment, new energy charging piles require terminals designed to meet specific needs such as high current carrying capacity, safety protection, and environmental adaptability. Functionally, terminals can be categorized as follows: General terminals: used for basic electrical connections to ensure continuity between wires. Fuse terminals: provide overload protection; when the current exceeds a certain value, the internal fuse activates, cutting off the circuit and protecting the equipment and wiring. Test terminals: function as switches; the sliding metal part can withstand the maximum operating current through the terminal clamp. Switching is achieved by loosening the screw with a screwdriver and moving the slider. Test sockets are located at both ends for connection testing. Grounding terminals: specifically used to connect the grounding wire, ensuring a reliable connection between the equipment's casing and the earth, guaranteeing personal and equipment safety.

[0003] In the prior art, traditional terminal block materials prevent personnel from contacting live parts to prevent electric shock accidents and protect electrical equipment from external environmental influences. They are usually equipped with anti-electric shock covers. However, the position and angle of the anti-electric shock covers are usually fixed, so the terminal blocks may be difficult to connect to wires in other angular directions, reducing their scope of use. Utility Model Content

[0004] The purpose of this invention is to address the problem that in the prior art, the position and angle of the anti-electric shock cover are usually fixed, making it difficult to connect the terminal block to wires in other angular directions, thus reducing its application range. Therefore, this invention proposes a one-to-one terminal block with a protective cover.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a one-to-one terminal block with a protective cover, comprising a base, a fixing ring fixedly installed on the outer wall of the base, an anti-electric shock cover provided on the top of the base, two rotating plates fixedly installed on the bottom of the anti-electric shock cover, rotating grooves extending through the opposite sides of the two rotating plates, a storage groove provided on the top surface inside one of the two rotating grooves, a threaded rod rotatably installed on the top surface inside the storage groove, a rotating shaft fixedly installed on the top of the threaded rod, a handle fixedly installed on the top of the rotating shaft passing through the rotating plate and the anti-electric shock cover, a pressure plate slidably installed inside the storage groove, a threaded groove provided on the top of the pressure plate, and the threaded rod threadedly connected to the threaded groove.

[0006] Preferably, the base has mounting holes at all four corners of its top.

[0007] Preferably, a waterproof pad is fixedly installed at the bottom of the base, and through holes are provided at the four corners of the bottom of the waterproof pad.

[0008] Preferably, a copper guide post is installed through and fixedly mounted on the top of the base, a second threaded hole is opened on the top of the copper guide post, a screw is provided on the inner wall of the second threaded hole, and a first threaded hole is opened through the outer wall of the copper guide post.

[0009] Preferably, a marking plate is fixedly installed on the top of the anti-electric shock cover.

[0010] Preferably, the outer wall of the pressure plate is in contact with the inner wall of the storage tank.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, during use, the operator rotates the anti-electric shock cover according to the wire connection direction, so that the connection port faces the wire. The anti-electric shock cover drives the rotating plate to rotate along the fixed ring, so that the fixed ring rotates in the rotating groove. When the adjustment is finished, the operator rotates the handle, which drives the rotating shaft to rotate, and then drives the threaded rod to rotate. At this time, since the threaded rod is threadedly connected to the threaded groove, the pressure plate descends along the storage groove. The pressure plate contacts the top of the fixed ring, and the pressure plate applies pressure to the fixed ring, increasing the friction between the two, thereby fixing the pressure plate, which in turn fixes the anti-electric shock cover. In this way, the adjustment can be completed, and the application range is improved.

[0013] 2. In this utility model, during installation, the worker uses bolts to pass through the mounting holes and through holes to fix the base to the machine body or equipment. At this time, the waterproof gasket can enhance the sealing performance, reduce the probability of water entering the threaded connection, thereby reducing the probability of bolt corrosion and improving the stability of installation.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figures 1-4 As shown, this utility model provides a pair of terminals with protective covers, including a base 1, a fixing ring 11 fixedly installed on the outer wall of the base 1, an anti-electric shock cover 5 provided on the top of the base 1, two rotating plates 7 fixedly installed at the bottom of the anti-electric shock cover 5, and rotating grooves 8 extending through the opposite sides of the two rotating plates 7. A storage groove 16 is provided on the top surface inside one of the two rotating grooves 8, and a threaded rod 19 is rotatably installed on the top surface inside the storage groove 16. A rotating shaft 10 is fixedly installed on the top of the threaded rod 19, and a handle 9 is fixedly installed on the top of the rotating shaft 10 through the rotating plate 7 and the anti-electric shock cover 5. A pressure plate 17 is slidably installed inside the storage groove 16, and a threaded groove 18 is provided on the top of the pressure plate 17. The threaded rod 19 is threadedly connected to the threaded groove 18.

[0022] The effect achieved by the entire embodiment 1 is as follows: During use, the operator rotates the anti-electric shock cover 5 according to the wire connection direction, so that the connection port faces the wire. The anti-electric shock cover 5 drives the rotating plate 7 to rotate along the fixed ring 11, so that the fixed ring 11 rotates in the rotating groove 8. When the adjustment is finished, the operator rotates the handle 9, which drives the rotating shaft 10 to rotate, and then drives the threaded rod 19 to rotate. At this time, since the threaded rod 19 is threadedly connected to the threaded groove 18, the pressure plate 17 descends along the storage groove 16 and contacts the top of the fixed ring 11. The pressure plate 17 applies pressure to the fixed ring 11, increasing the friction between the two, thereby fixing the pressure plate 17, which in turn causes the anti-electric shock cover 5 to be fixed. In this way, the adjustment can be completed, and the range of use is improved.

[0023] Example 2, as Figures 1-4As shown, furthermore, mounting holes 2 are provided through the four corners of the top of the base 1.

[0024] Furthermore, a waterproof pad 13 is fixedly installed at the bottom of the base 1, and through holes 14 are opened at the four corners of the bottom of the waterproof pad 13.

[0025] Furthermore, a copper guide post 3 is installed through and fixedly mounted on the top of the base 1. A second threaded hole 15 is opened on the top of the copper guide post 3. A screw 12 is provided on the inner wall of the second threaded hole 15. A first threaded hole 4 is opened through the outer wall of the copper guide post 3.

[0026] Furthermore, a marking plate 6 is fixedly installed on the top of the anti-electric shock cover 5. The marking plate 6 is used to warn people in the vicinity that there is electricity here, preventing people from accidentally touching it and being injured.

[0027] Furthermore, the outer wall of the pressure plate 17 is in contact with the inner wall of the storage groove 16 to prevent the pressure plate 17 from rotating when the threaded rod 19 rotates.

[0028] The effect achieved by the entire embodiment 2 is that during installation, the staff uses bolts to pass through the mounting hole 2 and the through hole 14 to fix the base 1 to the machine body or equipment. At this time, the waterproof gasket 13 can enhance the sealing performance, reduce the probability of water entering the threaded connection, thereby reducing the probability of bolt corrosion and improving the stability of the installation.

[0029] Working Principle: During use, the operator rotates the anti-electric shock cover 5 according to the wire connection direction, aligning the connection port with the wire. The anti-electric shock cover 5 drives the rotating plate 7 to rotate along the fixed ring 11, causing the fixed ring 11 to rotate within the rotating groove 8. When adjustment is complete, the operator rotates the handle 9, which drives the rotating shaft 10 to rotate, thereby rotating the threaded rod 19. Since the threaded rod 19 is threadedly connected to the threaded groove 18, the pressure plate 17 descends along the storage groove 16, contacting the top of the fixed ring 11. The pressure plate 17 applies pressure to the fixed ring 11, increasing the friction between them, thus fixing the pressure plate 17 in place, which in turn fixes the anti-electric shock cover 5. This completes the adjustment and expands its application range. During installation, the operator uses bolts to pass through the mounting hole 2 and the through hole 14 to fix the base 1 to the machine body or equipment. The waterproof gasket 13 enhances the seal, reducing the probability of moisture entering the threaded connection, thus reducing the probability of bolt corrosion and improving installation stability. When installing the wire, the worker places the metal part of the wire next to the second threaded hole 15, and then inserts the bolt into the second threaded hole 15. At this time, the metal part of the wire is held by the bolt head and the copper guide post 3, thus completing the connection. The worker can also use a bolt to pass through the first threaded hole 4 to fix the copper guide post 3 in place. The marking plate 6 is used to warn surrounding personnel that there is electricity in the area, preventing accidental contact and potential injury.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
