[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0054] This invention provides a vertical crimping tool, which is easy to carry and allows a single person to complete wiring, wire cutting, or crimping of copper connectors.

[0055] like Figure 1 As shown, this vertical wire crimping tool includes a wire cutting mechanism and a wire stripping mechanism.

[0056] The wire-cutting mechanism includes:

[0057] The base plate 40 has four sets of support poles 41 at its upper end, and the upper end of the support poles 41 has a threaded section, and a wire break plate 43 is provided on the threaded section through a set of nuts 42.

[0058] A hollow cutting clamp 44 is provided on the wire cutting plate 43. A wire cutting block 45 is slidably installed inside the hollow cutting clamp 44. A limit pin 46 is provided at the upper end of the hollow cutting clamp 44.

[0059] A jack 48 is installed on the base plate 40, and the telescopic end of the jack 48 is connected to the tangent block 45.

[0060] The wire stripping mechanism is rotatably mounted on one of the support columns 41, and a spring plunger 47 is provided on the base plate 40 for limiting the rotation of the wire stripping mechanism.

[0061] The wire stripping mechanism includes: a frame 1, which is arranged in a U-shape, and two sets of protrusions are integrally formed on one side of the frame 1, and mounting holes 2 are provided on the protrusions; the frame 1 includes: an upper beam column, a base and a support column;

[0062] The design of mounting hole 2 makes it easy to fix this crimping tool in the work environment for convenient use.

[0063] like Figure 1 and Figure 5 The tooling fixture assembly 3 shown is installed inside the base. The tooling fixture assembly 3 includes:

[0064] The integrated wire stripping die 4 and the steering assembly 5 for adjusting the integrated wire stripping die 4; the integrated wire stripping die 4 includes:

[0065] Positioning mold 9, on which two sets of V-shaped grooves 10 are symmetrically opened;

[0066] One set of V-grooves 10 contains several sets of stripping mechanisms 12, and each set of stripping mechanisms 12 includes:

[0067] Vertical cutting blades 13 are arranged in pairs, and the vertical cutting blades 13 are inclined at an angle of 15°-30° with the vertical line of the positioning mold 9.

[0068] The above design makes it easier to strip the wire insulation because the vertical cutting blade 13 has a certain tilt angle. If it were set to a vertical blade, only two sets of short cuts could be made on the wire insulation when stripping the wire, which would be inconvenient.

[0069] like Figure 1 As shown, the steering component 5 includes:

[0070] Insertion pins 14 and connecting pins 15 are respectively set on the opposite side walls of the positioning mold 9;

[0071] A rotary damper 16 is embedded in the inner wall of the frame 1, and one end of the plug post 14 is inserted into the inner ring of the rotary damper 16.

[0072] A through hole is provided on the frame 1, and a rotating bearing 17 is installed inside the through hole. The connecting column 15 is inserted into the inner ring of the rotating bearing 17, and one end of the connecting column 15 passes through the rotating bearing 17 and is located on the outside of the frame 1. A rotating handle 18 is keyed to one end of the connecting column 15.

[0073] The design of the steering component 5 allows the positioning module 9 to be rotated according to actual usage needs, thus enabling functional changes.

[0074] like Figure 1 , 3 As shown in Figure 4, the pressing assembly 6 is installed on the upper beam and column of the frame 1. The pressing assembly 6 includes:

[0075] The drive structure 7 and the pressure head structure 8 used in conjunction with the output end of the drive structure 7 are located directly above the integrated stripping die 4. The drive structure 7 includes:

[0076] Hollow column 19 is welded and fixed to the upper beam and column of frame 1;

[0077] A cylindrical gear 20 is rotatably installed inside the hollow column 19. One end of the cylindrical gear 20 passes through the hollow column 19 and is connected to a rotating block. A blind hole is provided on the rotating block.

[0078] In use, insert the handle of any cylindrical tool, such as a screwdriver, electric pen, or pliers, into the blind hole, rotate the rotating block, and the rotating block will drive the cylindrical gear 20 to rotate, thereby driving the rack 22 to move through the cylindrical gear 20, so that the pressure head 23 moves towards the positioning mold 9 to complete the operation.

[0079] It is worth noting that the pressure head structure 8 includes:

[0080] A column 21 is inserted into the hollow column 19. A rack 22 is provided on one side of the column 21, and the rack 22 meshes with a cylindrical gear 20. A pressure head 23 is provided at the lower end of the column 21.

[0081] A fixing plate 25 is fixed to the upper end of the column 21, and a tension spring 26 is installed on the lower surface of the fixing plate 25. A hook 27 is provided at the upper end of the hollow column 19, and one end of the tension spring 26 is connected to the hook 27.

[0082] When the rotating block causes the cylindrical gear 20 to move the rack 22 downward, the rack 22 can be quickly returned to its original position by the tension spring 26, which makes it easy to remove the pressed copper connector from the positioning mold 9 and facilitates the next operation.

[0083] Two sets of limiting posts 34 are symmetrically arranged on the inner wall of the hollow column 19, and two sets of limiting grooves 35 corresponding to the two sets of limiting posts 34 are symmetrically opened on the side wall of the column 21. The limiting posts 34 are slidably inserted into the inside of the limiting grooves 35.

[0084] The above design ensures that the column 21 will not slip out of the hollow column 19 when it moves up and down, thus ensuring the stability of the structure.

[0085] like Figure 1 and Figure 2 As shown, this vertical crimping tool also includes:

[0086] The limiting mechanism 24 is used to limit the tooling fixture assembly 3. One end of the limiting mechanism 24 is engaged with the side wall of the integrated pressing and stripping mold 4. A U-shaped insert 33 with a cross-section is welded and fixed on the side wall of the positioning mold 9 of the tooling fixture assembly 3. One end of the limiting mechanism 24 is inserted into the insert 33.

[0087] The limiting mechanism 24 includes:

[0088] The connector 28 has a socket 29 on the support column of the frame 1, and the connector 28 is slidably inserted into the socket 29.

[0089] A limiting plate 30 is fixed to one end of the plug rod 28, and a pull ring is provided on one side of the limiting plate 30;

[0090] The abutment piece 31 is integrally formed with the plug rod 28. A compression spring 32 is fitted on the plug rod 28, and the two ends of the compression spring 32 abut against the side wall of the abutment piece 31 and the side wall of the support column of the frame 1, respectively.

[0091] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
