Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-4 The utility model provides a power distribution automation terminal connection device, including a mounting plate 3 and a terminal body 2. The mounting plate 3 is fixed at the destination position by bolts. A U-shaped block 1 is welded and fixed on one side of the mounting plate 3. A limiting groove 4 is provided on the outer side of the terminal body 2. There are four limiting grooves 4, two of which form a group and are symmetrically provided on both sides of the terminal body 2. The inner diameter of the upper limiting groove 4 is larger than that of the lower limiting groove 4. A hole groove 5 is provided inside the U-shaped block 1. A limiting rod 11 is slidably provided inside the hole groove 5. The limiting rod 11 is matched with the limiting groove 4 on the same horizontal line. The inner diameter of the upper hole groove 5 is larger than that of the lower hole groove 5. A spring 13 is welded and fixed between the limiting rod 11 and the inner side wall of the hole groove 5. An extension rod 12 is welded and fixed on one side of the limiting rod 11. A through hole 6 is provided on the outer side of the U-shaped block 1. The extension rod 12 movably passes through the through hole 6 and extends to the outer side of the U-shaped block 1. One side of the extension rod 12 is provided with a moving mechanism for conveniently moving the limit rod 11. The upper end of the limit rod 11 close to the terminal body 2 is a smooth inclined surface. When in use, the terminal body 2 is inserted into the U-shaped block 1 from the upper end of the U-shaped block 1. When the terminal body 2 moves, the arc-shaped end position of the limit rod 11 is squeezed, so that the limit rod 11 is recovered to the inside of the hole groove 5, and the spring 13 is squeezed and compressed. The limit groove 11 at the lower end of the terminal body 2 is first aligned with the upper end hole groove 5. Since the specification of the limit groove 4 is smaller than that of the upper end limit rod 11, the terminal body 2 continues to move downward until the lower end limit groove 11 is aligned with the lower end hole groove 5, and the upper end limit groove 11 is aligned with the upper end hole groove 5. The spring 13 is reset, so that the limit rod 11 is inserted into the corresponding limit groove 11. In this way, the position of the terminal body 2 is fixed, so there is no need to fix it by bolts, and the fixation is simple and convenient.
[0021] The moving mechanism includes a first connecting rod 7, a second connecting rod 8, a slot body 10 and an operating plate 9. The first connecting rod 7 is welded and fixed on one side of the extension rod 12, the second connecting rod 8 is welded and fixed on one side of the first connecting rod 7, the slot body 10 is opened on one side of the U-shaped block 1, the second connecting rod 8 is movably inserted into the slot body 10, and the operating plate 9 is welded and fixed on one side of the second connecting rod 8. When disassembly is required, the second connecting rod 8 is moved through the operating plate 9, so that the first connecting rod 7 drives the extension rod 12 to move, so that the limit rod 11 is disengaged from the limit slot 4, thereby facilitating the disassembly of the terminal body 2.
[0022] Working principle: when in use, the terminal body 2 is inserted into the U-shaped block 1 from the upper end of the U-shaped block 1. When the terminal body 2 moves, the arc end position of the limiting rod 11 is squeezed, so that the limiting rod 11 is recovered to the inside of the hole groove 5, and the spring 13 is squeezed and compressed. The limiting groove 11 at the lower end of the terminal body 2 is first aligned with the upper hole groove 5. Since the specification of the limiting groove 4 is smaller than that of the upper limit rod 11, the terminal body 2 continues to move downward until the lower limit groove 11 is aligned with the lower hole groove 5, and the upper limit groove 11 is aligned with the upper hole groove 5. The spring 13 is reset, so that the limiting rod 11 penetrates into the corresponding limiting groove 11, so that the position of the terminal body 2 is fixed, so there is no need to fix it by bolts, the fixing is simple and convenient, and the practicality of the device is improved; when disassembly is required, the second connecting rod 8 is moved by the operating panel 9, so that the first connecting rod 7 drives the extension rod 12 to move, so that the limiting rod 11 is separated from the limiting groove 4, which facilitates the disassembly of the terminal body 2.
