[0032] Specific implementation method eight: Figure 1-11 As shown, this embodiment is a further explanation of the specific embodiment 1. After the extrusion plate 27 contacts the corresponding pressing block II 311 and pushes the pressing block II 311 to move upward, the pressing block I 36 and the remaining pressing blocks II 311 contact the terminal 6.

[0033] Specific implementation method nine: Figure 1-11 As shown, this embodiment records a method for using a terminal block machine, and the method includes the following steps:

[0034] Step 1: Place the terminal block 6 into the cross slot 13 and fix it with the slide bar 14;

[0035] Step 2: Insert the wire 5 into the terminal 6;

[0036] Step 3: Push the two movable devices 2 to move toward each other. After they move to the end, use two fixing blocks 4 to fix the positions of the two movable devices 2.

[0037] Step 4: Press down the pressure device 3 to complete the installation;

[0038] Step 5: Pull the wire 5 to pull the terminal 6 out of the cross slot 13 and check whether the crimping is firm.

[0039] The working principle of the present invention is as follows: when using the device, the terminal 6 is placed in the cross slot 13, and after the collar portion of the terminal 6 is inserted into the rear cross slot 13 and contacts the slide bar 14, since the lower end of the slide bar 14 is set to be tapered, the terminal 6 is pushed, so that the terminal 6 pushes the slide bar 14 upward through the tapered surface of the lower end of the slide bar 14, and compresses the spring I 15, and then continues to push, the slide bar 14 moves downward under the action of the spring I 15, and is inserted into the collar of the terminal 6, and the terminal 6 is fixed by the slide bar 14; then the wire 5 is inserted into the terminal 6;

[0040] Subsequently, the two movable devices 2 are pushed to move toward each other. After the two rotating plates 21 are moved to be parallel, the positions of the two movable devices 2 are fixed by using two fixing blocks 4. The two fixing blocks 4 are provided with fixing grooves. One of the fixing blocks 4 is rotated around the hinge, and then the two fixing blocks 4 are connected through the fixing grooves, thereby limiting the rotation of the rotating plate 21. During the rotation of the rotating plate 21, the squeezing plate 27 moves along with it. After the squeezing plate 27 moves to the upper end of the bottom plate 11, it contacts the wiring terminal 6. As the rotating plate 21 rotates, the squeezing plate 27 gradually becomes parallel and compresses the spring II 23, so that the two squeezing plates 27 fix the wiring terminal 6. At the same time, the squeezing plate 27 can be adjusted according to the size of the wiring terminal, saving time.

[0041] Then, the bottom plate 11 is placed on the desktop, and the pressure rod 32 is pressed downward. The pressure blocks I36 and II311 move to the top of the terminal 6 as the pressure rod 32 rotates. As the pressure rod 32 continues to rotate, the pressure blocks II311 located on both sides of the pressure block I36 contact the extrusion plate 27 higher than the terminal 6 (depending on the size of the terminal 6, the pressure blocks II311 contacting the extrusion plate 27 are also different. When the terminal 6 is large, the pressure blocks II311 farther from the pressure block I36 contact the extrusion plate 27. When the terminal 6 is small, the pressure blocks II311 closer to the pressure block I36 contact the extrusion plate 27). And as the pressure rod 32 rotates, the pressure blocks II311 contacting the extrusion plate 27 move to the concave side. The pressure rod 32 continues to rotate, and the pressure block I36 and the pressure block II311 located between the two extrusion plates 27 also approach the wiring terminal 6. At this time, the transmission rod 37 exposed at the lower end of the pressure block I36 contacts the wiring terminal 6 first. The pressure rod 32 continues to rotate, pushing the transmission rod 37 to move into the recess 39 and compressing the spring III34. After the lower end of the transmission rod 37 completely enters the pressure block I36, the top of the transmission rod 37 is exposed above the pressure block I36, and when the top of the transmission rod 37 moves upward, it pushes the two sliding rods 384 to move in the opposite direction and compresses the spring V315. As the sliding rod 384 moves, the sliding rod 384 drives the spring VI386 to move. The sleeve 381 is pushed to move by the elastic force of spring VI 386 until the sleeve 381 contacts the side wall of the upwardly protruding pressure block II 311 (i.e., the pressure block II 311 in contact with the extrusion plate 27). When the lower end of the transmission rod 37 completely enters the pressure block I 36, the sliding rod 384 breaks away from the inclined surface at the top of the transmission rod 37 and contacts its side surface. Since the pressure block I 36 is fixedly connected in the recess 39 and the pressure block I 36 is connected to the sliding rod 384 through the T-shaped slider II 385 and the T-shaped slot I 310, the movement of the sliding rod 384 in directions other than the horizontal direction is restricted. The sliding rod 384 is connected to the sleeve 381 through the T-shaped slider I 383 and the T-shaped slot II 382. Therefore, the sleeve 381 can only move horizontally. The pressing rod 32 moves in the direction, and as the pressing rod 32 continues to rotate, the pressing block I36 and the pressing block II311 located between the two extrusion plates 27 press on the upper end of the terminal 6. Since the sleeve 381 and the sliding rod 384 are located at the upper ends of the pressing block I36 and the pressing block II311 that is not in contact with the extrusion plate 27 at this time, the pressing block II311 that is not in contact with the extrusion plate 27 cannot move into the recess 39 and can only be at the same height as the pressing block I36. Therefore, as the pressing rod 32 rotates to be parallel to the bottom plate 11, the extrusion plate 27 contacts the lower end surface of the pressing rod 32, and the pressing block I36 and the pressing block II311 that is not in contact with the extrusion plate 27 exert pressure on the terminal 6, crimping the terminal 6 and the wire 5 together to complete the installation;After the installation is completed, the pressure rod 32 is lifted upward. Because the elastic force of the spring IV313 is greater than the elastic force of the spring VI386, the extrusion force applied by the two sliding rods 384 to the transmission rod 37 through the spring VI386 is less than the elastic force of the spring IV313. Therefore, the transmission rod 37 moves to the original position under the action of the elastic force, and the sliding rod 384 and the sleeve 381 also move to the original position under the action of the spring V315. Finally, the fixing block 4 can be opened;

[0042] When taking out the terminal 6, directly pull the wire 5 to pull the terminal 6 out of the cross slot 13. Since the sliding bar 14 needs to be driven to move upwards during the pulling process, the sliding bar 14 will exert resistance such as friction when the terminal 6 moves. Therefore, a large force is required to pull the wire 5. When the wire 5 and the terminal 6 are not crimped firmly, the wire 5 will directly break away from the terminal 6, while the terminal 6 is still in the cross slot 13. If the crimping is firm, the terminal 6 will be pulled out by the wire 5, and then check whether the crimping is firm.

[0043] The length of the pressing block I36 is smaller than the minimum width of the terminal 6. At the same time, the portion of the terminal 6 exposed at the outer end of the cross slot 13 will be pressed by the pressing block I36 and the pressing block II311 to be crimped with the wire 5, so that the crimping range is wider and the crimping is further ensured to be more secure.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other forms of assembly without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
