[0028] Reference Figure 1-5 As shown, the utility model provides a technical solution: a double-layer terminal block, comprising a shell 1, an assembly frame 2 is detachably installed on the inner side of the shell 1, two rows of through holes 3 are evenly opened on the back side of the shell 1, and a metal frame 5 is fixedly installed on the inner side of the shell 1.
[0029] The following is a detailed description of its overall specific settings and functions.
[0030] In this embodiment: a push block 4 is slidably installed on the back side of the housing 1, a pressing piece 6 is fixedly installed on the inner side of the metal frame 5, and a plurality of spring pieces 8 in groups of two are fixedly connected to the end side of the metal frame 5. The spring pieces 8 are of a "V"-shaped structure. Two rows of wire insertion holes 9 are opened on the surface of the assembly frame 2, and a circular ring 10 is fixedly installed on the inner side of the wire insertion hole 9. When it is necessary to perform wiring work inside the double-layer terminal, the push block 4 is pushed, and the push block 4 will push the pressing piece 6 to open. At this time, the wire can be inserted through the through hole 3 into the position between the pressing piece 6 and the metal frame 5, and the push block 4 is released. At this time, the pressing piece 6 will press the wire tightly on the upper side of the anti-skid groove 7 on the metal frame 5 due to its own elastic force. At this time, the fixing work of the wire at the port position of the double-layer terminal can be realized. Several anti-skid grooves 7 are evenly opened on the bottom side of the metal frame 5. By setting the anti-skid groove 7, the friction between the wire and the metal frame 5 is increased, and the stability of fixing the wire is improved.
[0031] Two push frames 11 are slidably connected inside the circular ring 10, and the push frames 11 are rectangular ring structures. The push frames 11 push the two corresponding springs 8 to open. The end sides of the two push frames 11 are fixedly installed with circular covers 13. The circular covers 13 can cover the wire cores and scratches on the wire skin. The side walls of the circular covers 13 are fixedly connected with push rings 14. The setting of the push rings 14 facilitates the pushing and pressing of the circular covers 13.
[0032] Specifically, a folding tube 12 is fixedly connected between the circular cover 13 and the assembly frame 2. The folding tube 12 improves the tightness of covering the wire core, thereby improving the safety of using the wire inserted into the wire insertion hole 9. A plurality of fixing pins 15 are fixedly connected to the surface of the assembly frame 2, and a baffle 16 is rotatably connected to the end side of the fixing pin 15. The baffle 16 located on the surface of the push ring 14 is rotated out, and the two spring pieces 8 are pressed against each other, so that the fixing work of the wire core between the two spring pieces 8 can be achieved.
[0033] Working principle: when it is necessary to perform wiring work inside the double-layer terminal, push the push block 4, which will push the pressing piece 6 to open. At this time, the wire can be inserted through the through hole 3 into the position between the pressing piece 6 and the metal frame 5. Release the push block 4. At this time, the pressing piece 6 will press the wire tightly to the upper side of the anti-slip groove 7 on the metal frame 5 due to its own elastic force. At this time, the wire at the port position of the double-layer terminal can be fixed. By setting the anti-slip groove 7, the friction between the wire and the metal frame 5 is increased, and the stability of fixing the wire is improved. When fixing the wires at the lower port position, first push the push ring 14 to move to the side close to the assembly frame 2. The setting of the push ring 14 facilitates the pushing and pressing work on the circular cover 13. At this time, the push ring 14 will drive the push frame 11 to slide inside the circular ring 10, and the push frame 11 will push the two corresponding spring pieces 8 to open. After pushing the push ring 14 to a certain distance, rotate the baffle 16 on the fixing pin 15 to block the baffle 16 on the back side of the push ring 14. At this time, the support work of the push frame 11 position after moving can be realized, which is convenient for the two spring pieces 8. The holding work of the opening action is performed. At this time, the wire core on the wire can be sleeved on the inner side of the wire insertion hole 9. When the wire core moves to the distance between the two spring pieces 8, the baffle 16 located on the surface of the push ring 14 is turned out. At this time, the two spring pieces 8 squeeze each other, so that the wire core between the two spring pieces 8 can be fixed. The circular cover 13 can cover the wire core and the scratches on the wire surface. The folding tube 12 improves the tightness of covering the wire core, thereby improving the safety of using the wire inserted into the wire insertion hole 9. The push frame 11 is set to squeeze and fix the wire after the spring piece 8 is opened, avoiding the situation that the wire core is directly inserted between the two spring pieces 8 and easily causes bending, and improving the stability of fixing the position of the wire core. By setting the above structure, it is convenient to quickly connect and fix the wire and the double-layer terminal. Compared with the traditional wiring method, this wiring method has a fast wiring speed and will not cause serious wear to the wire during the twisting process, which improves the efficiency of wiring the wire inside the double-layer terminal to a certain extent.
