DETAILED DESCRIPTION
[0023] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will be combined with the drawings and embodiments, and the utility model will be further described in detail. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled person in the art without creative labor belong to the scope of protection of the utility model.
[0024] Embodiment one:
[0025] Reference Figure 1 A current voltage terminal disconnecting isolation lock, comprising a current terminal 10, the current terminal 10 is installed with left copper guide 11 and right copper guide 12, and metal piece 13 is installed between left copper guide 11 and right copper guide 12.
[0026] In the above scheme, the current terminal 10 adopts URTK / S series, and the movement of the metal piece 13 realizes the on-off of the circuit, the establishment of the test connection, the realization of the bridging and the clear identification of the switch position by changing the internal connection structure of the terminal. Figure 1 The position of the metal piece 13 indicates that the inside of the current terminal 10 is in the disconnected state; by moving the metal piece 13 close to the right copper guide 12, the inside of the current terminal 10 is in the connected state (for specific working principle, refer to the existing product / technology URTK / S series terminal).
[0027] Reference Figure 1 and Figure 2 The isolation lock is inserted into the current terminal 10, and the isolation lock is used to limit the displacement of the metal piece 13. The isolation lock comprises a hand-held part 20, an isolation part 21, and a protective buckle 26 arranged between the hand-held part 20 and the isolation part 21.
[0028] In the above scheme, when the metal piece 13 in the current terminal 10 is close to the left copper guide 11, the metal piece 13 is spaced apart from the right copper guide 12 at this time, and the isolation lock is inserted into the space; the worker holds the hand-held part 20, inserts the isolation part 21 into the space between the metal piece 13 and the right copper guide 12, and at this time the metal piece 13 is blocked by the position of the isolation part 21, that is, the metal piece 13 cannot move between the left copper guide 11 and the right copper guide 12, which can ensure that the circuit in the current terminal 10 is always in an open state, realize the anti-mislock of operating the breaking metal piece 13, and facilitate the worker to perform the isolation current test.
[0029] Further reference Figure 1 The isolation lock is inserted into the current terminal 10, and the width of the protective buckle 26 is just covered above the current terminal 10.
[0030] In the further embodiment, by inserting the isolation lock, the protective buckle 26 covering above the current terminal 10 can prevent dust from covering above the copper guide, and avoid that the dust accumulation may cause poor contact, short circuit or other electrical faults. The insertion of the isolation lock not only plays a role of physical isolation to prevent unauthorized operation or accidental contact with the current terminal 10, but also further enhances the safety by covering the protective buckle 26.
[0031] Further reference Figure 1 and Figure 2 The hand-held part 20 comprises a hand-held handle 22, and the isolation part 21 comprises an isolation column 24. The protective buckle 26 is connected between the isolation column 24 and the hand-held handle 22, and the thickness of the isolation column 24 is greater than the thickness of the hand-held handle 22.
[0032] In the further embodiment, the isolation lock is integrally formed by using plastic material. The thickness of the hand-held handle 22 is relatively thin, which can facilitate the worker to hold and exert force, and whether inserting or pulling out the isolation lock can provide comfortable and effective holding feeling, thereby improving the convenience and efficiency of operation; the thickness of the isolation column 24 is equal to the thickness of being inserted into the inside of the current terminal 10. The thickness design of the isolation column 24 can ensure stable contact against the metal piece 13 in the inside of the current terminal 10, and the close contact not only enhances the physical stability of the isolation lock, but also ensures the effective isolation of the current, thereby improving the safety of the equipment.
[0033] Further reference Figure 1 and Figure 2, one side of the bottom of the isolation column 24 is provided with a mark slot 25. The setting of the mark slot 25 increases the direction judgment, and the mark slot 25 serves as a visual reference point, providing clear direction judgment basis for the staff. When inserting the isolation lock, the staff can quickly and accurately determine the correct insertion direction of the isolation lock according to the position and shape of the mark slot 25. This reduces the operation failure caused by wrong direction, improves the work efficiency and safety, and enhances the user experience.
[0034] Further reference Figure 1 and Figure 2 , the left and right ends of the current terminal 10 are mirror image provided with grooves 14, the upper part of the groove 14 is provided with a slope 15, the lower part of the hand handle 22 is provided with a bending plate 23, wherein the bending plate 23 and the slope 15 are mutually matched, and the bending plate 23 and the slope 15 are mutually parallel.
[0035] In this further embodiment, when inserting the isolation lock, the hand handle 22 is inserted through the groove 14, and the bending plate 23 is matched with the slope 15, which provides additional stability for the installation of the isolation lock in the current terminal 10. When the isolation lock is inserted into the current terminal 10, the bending plate 23 slides along the slope 15 and finally matches with it, forming a physical locking mechanism. This mechanism effectively prevents accidental loosening of the isolation lock in the current terminal 10, ensuring safety and reliability. Because the thickness of the hand handle 22 is thin, it has a certain flexibility, which can produce a small amount of deformation during insertion. This deformation helps the bending plate 23 better adapt to the shape of the slope 15, so as to achieve closer matching. This design not only improves the flexibility of installation, but also helps to reduce damage or loosening caused by improper installation. During installation, the staff only needs to align the isolation lock with the groove 14 of the current terminal 10 and gently push it in, and the bending plate 23 will automatically slide along the slope 15 and match, without the need for additional fixing steps or tools, improving the installation efficiency, reducing the operation difficulty and cost.
[0036] Example two:
[0037] Reference Figure 1 , the distance from the left end of the right copper guide 12 to the rightmost end of the current terminal 10 is a; the length of the protective buckle plate 26 is a.
[0038] In the above scheme, for the length a of the protective buckle plate 26, the insertion mode of the isolation lock is on the right side, that is, the length a of the protective buckle plate 26 meets the distance a from the left end of the right copper guide 12 to the rightmost end of the current terminal 10.
[0039] Example three:
[0040] Reference Figure 1 and Figure 2 , the distance from the right end of the left copper guide 11 to the leftmost end of the current terminal 10 is b; the length of the protective buckle plate 26 is b.
[0041] In the above scheme, for the length b of the protective buckle plate 26, the insertion mode of the isolation lock is on the left, that is, the length b of the protective buckle plate 26 conforms to the distance b from the right end of the left copper guide 11 to the leftmost end of the current terminal 10.
[0042] Combined with the installation methods in Embodiment One and Embodiment Two: when the current terminal 10 is installed, the installation distance in the control box is limited, and the left direction or the right direction position is switched according to the use needs, so as to maximize the use of the available space in the control box. The design reduces the complexity in the installation process by providing two installation options of left and right.
[0043] When designing an electrical system, the relative positions and layouts of various components need to be considered. The design allows the current terminal 10 to be installed flexibly in the left and right directions, which helps to optimize the layout and wiring of the entire system. This not only improves the aesthetics and neatness of the system, but also reduces the number of cables and connectors used, reducing the cost and maintenance difficulty of the system.
[0044] The specific implementation process of the utility model is as follows:
[0045] The staff holds the hand-held part 20, inserts the isolation part 21 into the interval between the metal piece 13 and the right copper guide 12, at this time the metal piece 13 is blocked by the position of the isolation part 21, that is, the metal piece 13 cannot move between the left copper guide 11 and the right copper guide 12.
