[0027] A stable power distribution automation feeder terminal device includes: an intelligent feeder terminal body 1;

[0028] Wiring groove 2, the wiring groove 2 is opened in the middle of the bottom of the intelligent feeder terminal body 1, the wiring groove 2 is provided with wiring terminals 3 on all four sides, the wiring terminals 3 are connected to power cords 4, and one end of the power cord 4 is provided with a power cord connector 5.

[0029] The elastic device 6 is provided on both sides inside the wiring groove 2 and on both sides of the wiring terminal 3. A limit device 7 is slidably installed on one side of the elastic device 6.

[0030] The elastic device 6 includes a fixed plate 61, a sliding rod 62, an elastic element 63, and a limiting block 64. The fixed plate 61 is fixedly installed on one side of the inner wall of the wiring groove 2. The two sliding rods 62 are respectively fixedly installed on both sides of the outer surface of the fixed plate 61. The limiting block 64 is fixedly installed on one end of the sliding rod 62. The elastic element 63 is sleeved on one side of the outer surface of the sliding rod 62.

[0031] The limiting device 7 includes a limiting slide plate 71, sliding holes 73, limiting cavities 73, and a pressing inclined plate 74. The limiting slide plate 71 is slidably installed on the outer surface of the slide rod 61. The two sliding holes 73 are respectively opened on both sides of the outer surface of the limiting slide plate 71. The two limiting cavities 73 are respectively opened on both sides inside the limiting slide plate 71. The pressing inclined plate 74 is fixedly installed on the other side of the outer surface of the limiting slide plate 71.

[0032] The limiting cavity 73 and the sliding hole 73 are connected, and the diameter of the sliding hole 73 is smaller than the diameter of the limiting cavity 73.

[0033] The diameter of the slide rod 61 is adapted to the diameter of the slide hole 73, and the diameter of the limiting block 64 is adapted to the diameter of the limiting cavity 73.

[0034] The elastic element 63 adopts a spring structure. One end of the elastic element 63 is fixedly connected to the surface of the fixed plate 61, and the other end of the elastic element 63 is fixedly connected to the surface of the limiting slide plate 71. The restoring elastic force of the elastic element 63 pushes the limiting slide plate 71 away from the fixed plate 61.

[0035] The slide bar 62 slides inside the slide hole 72, and the limiting block 64 slides inside the limiting cavity 73, so that the limiting device 7 cannot disengage from the elastic device 6.

[0036] The working principle of the stable power distribution automation feeder terminal equipment provided by this utility model is as follows:

[0037] When in operation, the user first needs to insert the power cord connector 5 into the terminal 3. Simply align the power cord connector 5 with the terminal 3 and apply a certain pressure. The power cord connector 5 will squeeze the inclined plate 74. The inclined plate 74 will cause the limiting slide plate 71 to slide along the slide rod 62. The elastic element 63 will be compressed. When the power cord connector 5 is fully inserted into the terminal 3, the limiting slide plate 71 will slide back under the elastic force of the elastic element 63. At this time, the limiting slide plate 71 will block the surface of the power cord connector 5 and the terminal 3, providing support and limiting for the power cord connector 5 and preventing it from loosening and falling off.

[0038] Compared with related technologies, the power distribution automation feeder terminal equipment with stable connection provided by this utility model has the following beneficial effects:

The squeezing inclined plate 74 allows users to directly insert the power cord connector 5 into the terminal block. The elastic element 63, after the power cord connector 5 is connected to the terminal block 3, allows the limiting slide plate 71 to slide on the surface of the power cord connector 5 and block the surfaces of the power cord connector 5 and the terminal block 3, supporting the bottom of the power cord connector 5. This device has a simple structure, strong practicality, and can effectively avoid the problem of the wiring loosening and falling off due to vibration caused by factors such as wind in the outdoor environment, greatly improving the connection stability of the wiring.

[0044] Each limiting device 7 has threaded holes 8 on its limiting slide plate 71 surface.

[0045] The working principle of the stable power distribution automation feeder terminal equipment provided by this utility model is as follows:

[0046] During operation, the elastic element 63 first pushes the limiting slide plate 71 to support the bottom of the power cord connector. Then, the adjusting block 10 is rotated to drive the threaded rod 9 to rotate. The threaded rod 9 rotates and the threaded hole 8 is inserted into the limiting hole 11 to restrict the limiting slide plate 71, so that the limiting slide plate 71 is stably restricted at the bottom of the power cord connector 5.

This further enhances the stability of the connection between the power cord connector 5 and the terminal 3, effectively avoiding the loosening or detachment of the wiring caused by external factors. This allows the power distribution automation feeder terminal device to better adapt to the complex and ever-changing outdoor environment, improving the reliability and service life of the power cord connection.
