[0028] Reference Figure 1-5 As shown, the utility model provides a technical solution: a terminal block with anti-breakage connection, comprising a fixed shell 1, a mounting plate 2 is installed on the inner side of the fixed shell 1, a second metal sheet 6 is installed on the lower surface of the mounting plate 2, and a first metal sheet 5 is fixedly installed on the inner side of the second metal sheet 6.
[0029] The following is a detailed description of its overall specific settings and functions.
[0030] In this embodiment: the lower side of the first metal sheet 5 is a "V"-shaped structure, a push block 3 is slidably installed on the inner side of the fixed shell 1, and two extrusion blocks 7 are fixedly connected to the side wall of the push block 3, and four wire insertion holes 16 are opened on the lower surface of the fixed shell 1. When it is necessary to connect the wires inside the terminal, push the push block 3, and the push block 3 will drive the extrusion block 7 to squeeze the lower side of the first metal sheet 5. At this time, there will be a certain gap between the first metal sheet 5 and the second metal sheet 6. Insert the copper wire connector of the wire into the inner side of the wire insertion hole 16. When the connector of the wire moves to the position between the first metal sheet 5 and the second metal sheet 6, release the push block 3. At this time, the first metal sheet 5 will be reset by its own elastic force, and the fixing work of the wire connector between the first metal sheet 5 and the second metal sheet 6 can be realized. The surface of the second metal sheet 6 is evenly provided with a plurality of anti-skid grooves 8. By setting the anti-skid grooves 8, the stability of the copper wire connector extruded between the first metal sheet 5 and the second metal sheet 6 is increased.
[0031] Specifically, the lower surface of the fixed shell 1 is fixedly connected with two limit blocks 9, and the side walls of the two limit blocks 9 are rotatably connected with the rotating plate 4. The side walls of the fixed shell 1 are fixedly connected with two fixed blocks 10, and the fixed blocks 10 are internally slidably connected with two slide bars 12. The lower ends of the two slide bars 12 are fixedly installed with a limit frame 14, and the limit frame 14 is a "U"-shaped structure. The slide bar 12 slides inside the fixed block 10 to limit the moving direction of the limit frame 14. At this time, the limit frame 14 will push the two rotating plates 4 to rotate toward the side close to each other, so as to achieve the clamping work of the wires arranged between the two rotating plates 4. The internal thread of the fixed block 10 is connected with a screw rod 11, and the screw rod 11 is connected to the internal rotation of the limit frame 14. The screw rod 11 is driven to rotate inside the fixed block 10, so as to achieve the lifting work of the limit frame 14. The upper end of the screw rod 11 is fixedly installed with a rotating block 13, and the side wall of the rotating block 13 is provided with anti-slip grooves. When the rotating block 13 is rotated, the rotating block 13 drives the screw rod 11 to rotate inside the fixed block 10 .
[0032] The two ends of the limit frame 14 are rotatably connected with rollers 15. The rollers 15 slide on the side walls of the rotating plate 4 to reduce the friction between the limit frame 14 and the rotating plate 4. The lower side of the rotating plate 4 is fixedly connected with a plurality of ribs 17, and the ribs 17 are arc-shaped structures. By providing the ribs 17 with arc structures, the resistance between the rotating plate 4 and the wires is increased, and the stability of clamping and fixing the wires is further improved.
[0033] Working principle: when it is necessary to wire the wires inside the terminal, push the push block 3, and the push block 3 will drive the extrusion block 7 to squeeze the lower position of the first metal sheet 5. At this time, there will be a certain gap between the first metal sheet 5 and the second metal sheet 6. Insert the copper wire connector of the wire through the position between the two rotating plates 4 into the inner side of the wire insertion hole 16. When the connector of the wire moves to the position between the first metal sheet 5 and the second metal sheet 6, release the push block 3. At this time, the first metal sheet 5 will be reset by its own elastic force. At this time, the fixing of the wire connector between the first metal sheet 5 and the second metal sheet 6 can be achieved. By setting the anti-slip groove 8, the stability of the copper wire connector squeezed between the first metal sheet 5 and the second metal sheet 6 is increased. At this time, rotate the rotating block 13, and the rotating block 13 will drive the screw rod 11 to rotate inside the fixed block 10, so as to realize the lifting of the limit frame 14, wherein the slide bar 12 is fixed The internal sliding of the block 10 serves to limit the moving direction of the limit frame 14. At this time, the limit frame 14 will push the two rotating plates 4 to rotate toward the side close to each other, and the roller 15 slides on the side wall of the rotating plate 4 to reduce the friction between the limit frame 14 and the rotating plate 4. At this time, the wires arranged between the two rotating plates 4 can be clamped, further improving the stability of fixing the wires, and avoiding the wire connector from slipping out and breaking from the inside of the first metal sheet 5 and the second metal sheet 6. By setting the ribs 17 with an arc structure, the resistance between the rotating plate 4 and the wires is increased, and the stability of clamping and fixing the wires is further improved. By setting the above structure, the stability of the wire plug after being inserted into the terminal block for use is improved, and the phenomenon of the copper wire position of the wire connector inside the terminal block breaking is avoided, which improves the stability of the terminal block during use to a certain extent.
