[0007] Preferably, the surface of upper blade is provided with strip-shaped hole, and the surface of lower blade is provided with circular hole.

[0008] Preferably, the two sides of lower blade are provided with threaded holes, the inside of threaded hole is provided with spring, one side of spring is provided with threaded plug, the other side of spring is fixedly installed with limiting plate, the side surface of limiting plate is fixedly installed with clamping head, and the two sides of sliding block are provided with clamping groove corresponding to clamping head.

[0009] Preferably, the cross section of sliding block and sliding slot is I-shaped, and the profiled head is slidably installed with lower blade through sliding block and sliding slot.

[0010] Preferably, the sliding block is mutually clamped with lower blade through clamping head and clamping groove.

[0011] Preferably, the top and front of sliding slot are open, and the back of sliding slot is closed.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the present invention provides a cable harness terminal crimping blade, which has the following advantages:

[0014] 1. This cable harness terminal crimping blade allows the forming head to be pushed forward, causing the slider to leave the groove of the lower blade, thus enabling the removal and replacement of the forming head; conversely, the forming head is embedded in the groove of the lower blade via the slider, enabling the installation of a new forming head; at the same time, the spring will push the clip into the clip slots on both sides of the slider, thus fixing the new forming head. This process achieves the advantage of convenient replacement of the forming head.

[0015] 2. The cable harness terminal crimping blade, by driving the threaded plug to penetrate deeper into the threaded hole, the spring is compressed and the force increases. The spring gives the clamp a strong pushing force, and the clamp inserts into the clamping grooves on both sides of the slider, so that the slider is tightly locked. Conversely, the threaded plug moves out of the threaded hole, the spring is compressed and the force of the clamp decreases, and the slider can be easily removed from the groove. This process realizes the fixation of the forming head and the adjustment of the locking force. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 A cable harness terminal crimping blade includes a lower blade 1 and an upper blade 2. The surface of the upper blade 2 is provided with a strip-shaped hole 3 for easy connection with a crimping device. The surface of the lower blade 1 is provided with a circular hole 4 for easy connection with a crimping device. The bottom of the upper blade 2 is provided with a forming groove 5, and the top of the lower blade 1 is provided with a sliding groove 6. The top and front of the sliding groove 6 are open, and the back of the sliding groove 6 is closed.

[0023] Please see Figures 1-4 A slider 7 is slidably installed inside the slide groove 6. The cross-section of the slider 7 and the slide groove 6 is I-shaped. A forming head 8 is fixedly installed on the top of the slider 7. A curved groove 9 is opened on the top of the forming head 8 for placing metal buckles. The forming head 8 is slidably installed with the lower blade 1 through the slider 7 and the slide groove 6.

[0024] Please see Figures 1-4 The lower blade 1 has threaded holes 10 on both sides, and a spring 11 is installed inside the threaded hole 10. A threaded plug 12 is installed on one side of the spring 11, and a cross groove is opened on one side of the threaded plug 12 to facilitate the insertion of tools and drive the threaded plug 12 to rotate. A limit plate 13 is fixedly installed on the other side of the spring 11, and a clamping head 14 is fixedly installed on the side of the limit plate 13. The slider 7 has slots 15 on both sides corresponding to the clamping head 14. The slider 7 is engaged with the lower blade 1 through the clamping head 14 and the slots 15.

[0025] Working principle: When in use, push the forming head 8 forward, and the slider 7 will leave the groove 6 of the lower blade 1, thereby realizing the disassembly and replacement of the forming head 8.

[0026] Conversely, the forming head 8 is embedded in the groove 6 of the lower blade 1 via the slider 7, thus enabling the installation of the new forming head 8; at the same time, the spring 11 will push the clip 14 into the clip slots 15 on both sides of the slider 7, thereby fixing the new forming head 8. This process achieves the advantage of convenient replacement of the forming head 8.

[0027] By driving the threaded plug 12 deeper into the threaded hole 10, the spring 11 is compressed and the force increases. The spring 11 will give the chuck 14 a strong push, and the chuck 14 will insert into the slots 15 on both sides of the slider 7, so that the slider 7 is tightly locked.

[0028] Conversely, when the threaded plug 12 moves outward from the threaded hole 10, the spring 11 is compressed and the thrust of the chuck 14 is reduced, and the slider 7 can be easily removed from the groove 6. This process achieves the fixing of the forming head 8 and the adjustment of the locking force.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
