[0037] Reference Figure 5 and Figure 6 The driven block 61 is provided with a temporary blocking component 7 in the sliding groove 32. The temporary blocking component 7 is used to make the slider 42 drive the driven block 61 to slide after the first clamping block 51 and the second clamping block 52 clamp the wiring harness. The temporary blocking component 7 includes a first magnet 71 and a second magnet 72. The first magnet 71 is fixedly connected to the bottom wall of the sliding groove 32, and the second magnet 72 is fixedly connected to the driven block 61.

The top wall of the sliding groove 32 is provided with an adjusting groove 33. The locking bolt 82 is located in the adjusting groove 33, and the locking bolt 82 is slidably connected to the adjusting groove 33. One end of the locking bolt 82 passes through the limit block 81 and abuts against the bottom wall of the sliding groove 32, and the locking bolt 82 is threadedly connected to the limit block 81. In this embodiment, a temporary blocking component 7 is also provided between the limit block 81 and the driven block 61. The temporary blocking component 7 is used to temporarily fix the driven block 61 and the limit block 81, that is, the two magnets of the temporary blocking component 7 are respectively fixedly connected to the two abutting surfaces of the driven block 61 and the limit block 81, so that when the driven block 61 abuts against the limit block 81, the two magnets can be adsorbed to each other for temporary fixation, so that the limit column 62 slides in the pushing groove 30, and the first clamping block 51 and the second clamping block 52 rotate in opposite directions to separate the first clamping block 51 and the second clamping block 52 from the wiring harness.

[0038] When the slider 42 just starts to slide, the driven block 61 will not slide under the action of the temporary blocking component 7, and the slider 42 drives the first clamping block 51 and the second clamping block 52 to slide relative to the driven block 61. Since the limiting column 62 is fixedly connected to the driven block 61, the limiting column 62 will not slide with the first clamping block 51 and the second clamping block 52, so the limiting column 62 slides in the pushing groove 30. The limiting column 62 is used to constrain the pushing groove 30, so that the first clamping block 51 and the second clamping block 52 are constrained by the limiting column 62 and the pushing groove 30. At the same time, the slider 42 rotates relative to the slider 42, so that the first clamping block 51 and the second clamping block 52, one end away from the slider 42, approach each other to clamp the wiring harness placed in the accommodating groove 31; when the first clamping block 51 and the second clamping block 52 cannot continue to rotate after clamping the wiring harness, the limit column 62 cannot continue to slide in the pushing groove 30, so that the slider 42 drives the driven block 61 to slide in the sliding groove 32 through the first clamping block 51 and the second clamping block 52, so that the driven block 61 drives the second magnet 72 to separate from the first magnet 71.

[0039] The temporary blocking component 7 is arranged between the limit block 81 and the driven block 61. When the wiring harness and the terminal are compacted, when the lead screw 41 rotates in the opposite direction to drive the slider 42 to slide in the opposite direction, the driven block 61 does not slide with the slider 42 first, so that the limit column 62 slides in the pushing groove 30, thereby separating the first clamping block 51 and the second clamping block 52 from each other and no longer clamping the wiring harness, so that the crimping mold 2 can compact the terminal and the wiring harness. The slider 42 can slide in the opposite direction to the initial position in advance to prepare for the next terminal compaction, thereby improving the terminal compaction work efficiency. When the slider 42 slides to the initial position, the slider 42 drives the driven block 61 to return to the initial position synchronously, so that the temporary blocking component 7 is fixed to the driven block 61 in the sliding groove 32.

The door frame 101 is fixedly connected to the bearing block 3. The steering ring 103 is arranged at the end of the bearing block 3 away from the door frame 101. The steering ring 103 is fixedly connected to the bearing block 3.

[0041] In order to further facilitate the use of the compacting device in this embodiment, an accordion-type protective cover is provided in the accommodating groove 31, and the two ends of the protective cover are respectively abutted against the slider 42 and the side wall of the accommodating groove 31 to prevent the wiring harness from sliding down to the screw 41 under the action of gravity, causing the wiring harness to be unable to slide in the accommodating groove 31. As the slider 42 moves, the accordion cover contracts or stretches.

[0042] The implementation principle of a wire harness terminal compacting device in the embodiment of the present application is as follows: when using the compacting device, first place the wire harness in the receiving groove 31, so that the end of the wire harness that is compacted by the skin stripping and the terminal is in contact with the positioning plate 9, and the wire harness is placed on the protective cover. At this time, the driving member is started to drive the lead screw 41 to rotate, and the rotation of the lead screw 41 drives the slider 42 to slide in the receiving groove 31, so that the protective cover shrinks; at this time, the driven block 61 will not slide under the action of the temporary blocking component 7, so that the slider 42 drives the first clamping block 51 and the second clamping block 52 relative to the driven block 61 slides, and since the limiting column 62 is fixedly connected to the driven block 61, the limiting column 62 will not slide with the first clamping block 51 and the second clamping block 52, so that the limiting column 62 slides in the pushing groove 30, and the limiting column 62 constrains the pushing groove 30, so that the first clamping block 51 and the second clamping block 52 rotate relative to the slider 42 at the same time under the joint action of the limiting column 62 and the pushing groove 30, so that the first clamping block 51 and the second clamping block 52 away from the slider 42 are close to each other, so as to clamp the wiring harness placed in the accommodating groove 31.

[0043] When the first clamping block 51 and the second clamping block 52 cannot continue to rotate after clamping the wiring harness, the limiting column 62 cannot continue to slide in the pushing groove 30, so that the slider 42 drives the driven block 61 to slide in the sliding groove 32 through the first clamping block 51 and the second clamping block 52, so that the driven block 61 drives the second magnet 72 to separate from the first magnet 71; when the driven block 61 starts to slide, the driven block 61 drives the linkage rope 102 to slide in the rope sliding groove 34, and as the linkage rope 102 slides, the linkage rope 102 drives the positioning plate 9 to rise vertically under the constraint of the vertical rod 201, so that the positioning plate 9 opens The accommodating groove 31, at this time, the first clamping block 51 and the second clamping block 52 drive the wire harness to slide in the accommodating groove 31 along with the slider 42 to load into the crimping mold 2, and at the same time drive the driven block 61 to slide in the sliding groove 32. When the driven block 61 abuts against the limit block 81, the limit block 81 prevents the driven block 61 from continuing to slide, and the temporary blocking component 7 between the driven block 61 and the limit block 81 abuts, so that the driven block 61 is fixed with the limit block 81. At this time, the length of the wire harness inserted into the terminal reaches the specified value, and then the body 1 is started so that the driving mechanism in the body 1 drives the crimping mold 2 to compact the terminal and the wire harness.

[0044] When the crimping mold 2 is working, the reverse starting drive drives the lead screw 41 to rotate in the reverse direction, and the lead screw 41 drives the slider 42 to slide in the reverse direction. At this time, the driven block 61 is fixed to the limit block 81 under the action of the temporary blocking component 7, so that the driven block 61 does not slide with the slider 42. At this time, the limit column 62 slides in the pushing groove 30. The limit column 62 is limited by the pushing groove 30 to make the first clamping block 51 and the second clamping block 52 rotate and move away from each other, so that the first clamping block 51 and the second clamping block 52 no longer clamp the wiring harness, so that the crimping mold 2 can compact the terminal and the wiring harness. The slider 42 can slide in the reverse direction to the initial position in advance to prepare for the next compaction of the terminal. When the slider 42 slides to the initial position, the slider 42 drives the driven block 61 to return to the initial position synchronously, so that the temporary blocking component 7 fixes the driven block 61 in the sliding groove 32.
