[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0026] See also Figure 1-4 The utility model provides a technical solution: a quick-plug terminal block, comprising:

[0027] A terminal block body 100, a connection hole 101 is provided on the front of the terminal block body 100, a concave groove corresponding to the connection hole 101 is provided on the upper surface of the terminal block body 100, and a positioning hole 102 connected to the connection hole 101 is provided on the inner bottom wall of the concave groove;

[0028] The connecting component 200 includes a mounting frame 201 fixedly mounted on the upper surface of the terminal block body 100 and corresponding to the concave groove, and a circular hole 202 opened on the upper surface of the mounting frame 201, an insulating column 203 is slidably arranged on the inner wall of the circular hole 202, a positioning column 204 slidably connected to the inner wall of the positioning hole 102 is fixedly arranged at the bottom end of the insulating column 203, a rotating disk 205 is rotatably arranged on the outer surface of the insulating column 203, and a clamping spring 206 is sleeved on the outer surface of the insulating column 203, and both ends of the clamping spring 206 are respectively fixedly connected to the inner top wall of the mounting frame 201 and the upper surface of the rotating disk 205.

[0029] In summary, by setting the connection component 200, when the terminal row is actually connecting the wire, after the wire is inserted into the connecting hole 101, the insulating column 203 and the positioning column 204 are rotated by rotating the rotating disk 205, so that the limit block 208 on the positioning column 204 corresponds to the limit slide groove 209. At this time, the positioning column 204 can be inserted into the positioning hole 102 under the action of the clamping spring 206, and the wire is pressed and connected. Finally, the rotating disk 205 is rotated again to make the limit block 208 located on the bottom wall of the limit slide groove 209 slide to the inside of the arc-shaped limit groove 2010, thereby effectively fixing the positioning column 204, thereby realizing quick connection between the wire and the terminal row body 100, and the operation is simple.

[0030] See also Figure 1 , Figure 3 A rotating hole is provided on the upper surface of the rotating disk 205, and a bearing 207 is arranged inside the rotating hole. The outer ring surface of the bearing 207 is fixedly connected to the inner wall of the rotating hole, and the inner ring surface of the bearing 207 is fixedly connected to the outer ring surface of the insulating column 203, so that the insulating column 203 and the rotating disk 205 are in a rotating connection relationship, thereby facilitating the rotation of the insulating column 203 and the positioning column 204.

[0031] See also Figure 1 , Figure 3A limit block 208 is fixedly arranged on the outer surface of the positioning column 204, and a limit slot 209 adapted to the limit block 208 is provided on the inner wall of the positioning hole 102 for allowing the limit block 208 to slide up and down, and an arc-shaped limit slot 2010 is provided on the inner bottom wall of the limit slot 209 for limiting the limit block 208 and allowing the limit block 208 to rotate. When the wire is not installed, the positioning column 204 can be suspended in the positioning hole 102 under the action of the limit block 208, thereby facilitating the insertion of the wire. At the same time, the setting of the arc-shaped limit slot 2010 can facilitate the effective limiting of the positioning column 204 after the positioning column 204 is inserted into the positioning hole 102, thereby avoiding the loosening of the positioning column 204.

[0032] See also Figure 1 , Figure 2 An operating disk 2011 is fixedly disposed at the top of the insulating column 203 for facilitating pulling and rotating the insulating column 203 , and an insulating sleeve is sleeved on the outer surface of the pressing spring 206 , which facilitates the operation of the insulating column 203 and the positioning column 204 and can effectively avoid the generation of static electricity.

[0033] See also Figure 1 , Figure 4 A limiting component 300 for limiting the position of the wire inserted into the connecting hole 101 is provided on the front of the terminal block body 100. The limiting component 300 includes a fixing frame 301 fixed on the front of the terminal block body 100 and corresponding to the connecting hole 101, which can facilitate the limiting of the wire.

[0034] See also Figure 1 , Figure 4 Two symmetrical sliding plates 302 are slidably disposed on the inner wall of the fixed frame 301 , and arc-shaped rubber pads 303 for clamping the wires are fixedly disposed on the opposite surfaces of the two sliding plates 302 , so that the wires can be clamped by the two arc-shaped rubber pads 303 .

[0035] See also Figure 1 , Figure 4 , sliding openings are provided on both side surfaces of the fixed frame 301, and two sliding plates 302 are slidably connected to the inner walls of the sliding openings, a bidirectional lead screw 304 is rotatably provided on the inner wall of one sliding opening, a fixing rod 305 is fixedly provided on the inner wall of the other sliding opening, and the top of the bidirectional lead screw 304 extends to the upper surface of the fixed frame 301 and is fixedly provided with a rotating block 306 for rotating the bidirectional lead screw 304, and the surfaces of the two sliding plates 302 are respectively provided with threaded holes threadedly connected to the outer surface of the bidirectional lead screw 304, and through holes slidably connected to the outer surface of the fixing rod 305, so as to facilitate the effective clamping and fixing of the wire by rotating the rotating block 306.

[0036] In summary, by setting the limit assembly 300, after the wire is connected, the rotating block 306 can be rotated to drive the bidirectional screw 304 to rotate. The rotation of the bidirectional screw 304 drives the two sliding plates 302 to move toward the middle at the same time, thereby driving the two arc-shaped rubber pads 303 to move toward the middle at the same time, and clamping and fixing the wire, thereby effectively ensuring the stability of the wire end after connection with the terminal row main body 100, and avoiding careless pulling that causes the wire end to loosen from the terminal row main body 100.

[0037] During operation, after the wire is inserted into the connecting hole 101, the insulating column 203 and the positioning column 204 are rotated by rotating the rotating disk 205, so that the limiting block 208 on the positioning column 204 corresponds to the limiting slide groove 209. At this time, the positioning column 204 can be inserted into the positioning hole 102 under the action of the tightening spring 206, and the wire is pressed and connected. Finally, the rotating disk 205 is rotated again to make the limiting block 208 located on the bottom wall of the limiting slide groove 209 slide to the inside of the arc-shaped limiting groove 2010, so as to effectively fix the positioning column 204. The wire and the terminal block body 100 are quickly connected with each other, and the operation is simple. Moreover, after the wire is connected, the rotating block 306 can be rotated to drive the bidirectional screw 304 to rotate. The rotation of the bidirectional screw 304 drives the two sliding plates 302 to move toward the middle at the same time, thereby driving the two arc-shaped rubber pads 303 to move toward the middle at the same time and clamping the wire to fix it, thereby effectively ensuring the stability of the wire end after connection with the terminal block body 100, and avoiding the loosening of the wire end and the terminal block body 100 due to inadvertent pulling.
