Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal block technology, and in particular to a multi-interface terminal block with protective function. Background Technology
[0002] Terminal blocks are accessories used to achieve electrical connections. Belonging to the category of connectors, they facilitate the connection of wires. They are metal pieces encased in insulating plastic, with holes at both ends for inserting wires and screws for tightening or loosening. Their function is to achieve a safe and reliable connection between wires, ensuring smooth current transmission; facilitating wire connection and disconnection without soldering or winding, simplifying inspection and maintenance; suitable for interconnecting large numbers of wires, and can be used to form terminal blocks, terminal boxes, etc. The conductor of the cable is connected to the conductive element inside the terminal using screws, clamps, or springs. For example, the wire is inserted into the wire slot of the terminal, and then the screw is tightened, or the clamp or spring force is used to clamp the wire, achieving mechanical fixation and preventing the cable from loosening.
[0003] In existing technologies, if someone accidentally touches the conductive metal part of a conventional terminal block, it may cause electric shock, potentially resulting in electric shock injury or even endangering life. Furthermore, if dust or particulate matter accumulates on the conductive contact area of the terminal block, it may form an insulating layer, hindering current conduction, increasing contact resistance, and causing equipment to overheat, signal attenuation, or reduced power transmission efficiency. Utility Model Content
[0004] The purpose of this invention is to address the problems in existing technologies where, if someone accidentally touches the conductive metal part of a terminal block, they may suffer an electric shock, and if dust or particulate matter accumulates on the conductive contact area of the terminal block, it may cause the equipment to overheat. Therefore, this invention proposes a multi-interface terminal block with protective functions.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multi-interface terminal block with protective function, including a base, a placement seat fixedly installed on the top of the base, a knurled shaft inside the placement seat, a rotating seat on the outer wall of the knurled shaft, a torsion spring on the outer wall of the knurled shaft, one end of the torsion spring being fixedly connected to the rotating seat, an anti-electric shock rotating cover fixedly installed on the outer wall of the rotating seat, multiple separation openings through both sides of the anti-electric shock rotating cover, arc-shaped plates at both ends of the anti-electric shock rotating cover, a connecting seat fixedly installed on the outer wall of the anti-electric shock rotating cover, a slot at the bottom of the connecting seat, a slot groove on the inner side wall of the slot, a fixing seat fixedly installed on the top of the base, an insert plate fixedly installed on the top of the fixing seat, a limiting groove between the fixing seat and the insert plate, a spring fixedly installed on the inner wall of the limiting groove, a limiting plate fixedly installed on one end of the spring, a pressure plate and a locking block fixedly installed on the outer wall of the limiting plate, one end of the pressure plate and the locking block respectively penetrating the fixing seat and the insert plate.
[0006] Preferably, a marking plate is fixedly installed on the outer wall of the anti-electric shock rotating cover.
[0007] Preferably, a copper busbar is fixedly installed at the bottom of the base.
[0008] Preferably, the outer wall of the limiting plate is in contact with the inner wall of the limiting groove.
[0009] Preferably, the outer wall of the card block is in contact with the inner wall of the card slot.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0011] 1. In this utility model, during use, the operator presses the arc-shaped plate and removes it from the anti-electric shock rotating cover through the separation port. The cable can then be inserted into the anti-electric shock rotating cover for connection. The anti-electric shock rotating cover provides protection, preventing accidental contact with the metal parts of the cable and preventing external dust from adhering to them. To open the anti-electric shock rotating cover, the operator presses down the pressure plate, which, through the limiting plate, moves the locking block away from the slot. The operator can then rotate the anti-electric shock rotating cover to open it. To close the anti-electric shock rotating cover, it rotates in the opposite direction, allowing the insertion plate to enter the slot. The inclined surface of the locking block contacts the inner wall of the slot, causing it to move under pressure. The spring is compressed, and when the locking block moves to the side of the slot, it enters the slot under the spring's elastic force, thus completing the installation.
[0012] 2. In this utility model, the marking plate is equipped with an electric shock warning mark to remind people around that there is electricity, which increases the vigilance of people around and reduces the probability of accidental contact, thereby preventing people from being injured.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] 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.

A connecting seat 8 is fixedly installed on the outer wall of the rotating cover 3. A slot 19 is opened at the bottom of the connecting seat 8. A slot 20 is opened on the inner side wall of the slot 19. A fixing seat 7 is fixedly installed on the top of the base 2. An insert plate 13 is fixedly installed on the top of the fixing seat 7. A limiting groove 14 is opened between the fixing seat 7 and the insert plate 13. A spring 15 is fixedly installed on the inner wall of the limiting groove 14. A limiting plate 16 is fixedly installed at one end of the spring 15. A pressure plate 17 and a locking block 18 are fixedly installed on the outer wall of the limiting plate 16. One end of the pressure plate 17 and the locking block 18 respectively penetrates the fixing seat 7 and the insert plate 13.
[0021] The overall effect of Embodiment 1 is as follows: During use, the operator presses the arc-shaped plate 6 and removes it from the anti-electric shock rotating cover 3 through the separation port 5. The cable can then be inserted into the anti-electric shock rotating cover 3 for connection. The anti-electric shock rotating cover 3 provides protection, preventing accidental contact with the metal parts of the cable and preventing external dust from adhering to them. To open the anti-electric shock rotating cover 3, the operator presses down the pressure plate 17. The pressure plate 17, through the limiting plate 16, moves the locking block 18, disengaging it from the slot 20. The operator can then rotate the anti-electric shock rotating cover 3 to open it. To close the anti-electric shock rotating cover 3, it rotates in the opposite direction, allowing the insertion plate 13 to enter the slot 19. The inclined surface of the locking block 18 contacts the inner wall of the slot 19, causing it to move under pressure. The spring 15 is compressed, and when the locking block 18 moves to the side of the slot 20, it enters the slot 20 under the elastic force of the spring 15, thus completing the installation.
[0022] Example 2, as Figures 1-4 As shown, a marking plate 4 is further fixedly installed on the outer wall of the anti-electric shock rotating cover 3.
[0023] Furthermore, a copper busbar 1 is fixedly installed at the bottom of the base 2.
[0024] Furthermore, the outer wall of the limiting plate 16 fits against the inner wall of the limiting groove 14 to prevent the limiting plate 16 from tilting.
[0025] Furthermore, the outer wall of the card block 18 fits against the inner wall of the card slot 20. When the card block 18 enters the card slot 20, the connecting seat 8 can be fixed in place and will not shake.
[0026] The overall effect of embodiment 2 is that the marking plate 4 is equipped with an electric shock warning mark, which reminds people around that there is electricity, increases the vigilance of people around, reduces the probability of accidental contact, and thus prevents people from being injured.
[0027] Working principle: During use, the operator presses the arc-shaped plate 6 and removes it from the anti-electric shock rotating cover 3 through the separation port 5. The cable can then be inserted into the anti-electric shock rotating cover 3 for connection. The anti-electric shock rotating cover 3 provides protection, preventing accidental contact with the metal parts of the cable and preventing external dust from adhering to them. It allows for two-to-one or one-to-one wiring. To open the anti-electric shock rotating cover 3, the operator presses down the pressure plate 17. The pressure plate 17, through the limiting plate 16, moves the locking block 18, disengaging it from the slot 20. The operator can then rotate the anti-electric shock rotating cover 3 to open it. To close the anti-electric shock rotating cover 3, it rotates in the opposite direction, allowing the insertion plate 13 to enter the slot 19. The inclined surface of the locking block 18 contacts the inner wall of the slot 19, causing it to move under pressure. The spring 15 is compressed, and when the locking block 18 moves to the side of the slot 20, it enters the slot 20 under the elastic force of the spring 15, thus completing the installation. The marking plate 4 is equipped with an electric shock warning sign to alert nearby personnel that there is electricity, increasing their awareness and reducing the probability of accidental contact, thereby preventing injury. The copper busbar 1 is used to fix the device in the cabinet or equipment, and copper, being conductive, plays a crucial role in achieving high-current, high-power conductive connections in the electrical system.
