[0026] Example

[0027] Reference Figure 1-7A protective vehicle wiring harness connector includes a shell 1, wherein there are four shells 1, and the four shells 1 are stacked in a rectangular shape, a first mounting hole 2 and a second mounting hole 3 are respectively provided at both ends of the shell 1, a third mounting hole 4 is provided inside the shell 1, and the first mounting hole 2, the second mounting hole 3 and the third mounting hole 4 are communicated with each other and the central axis coincides, the shell 1 is located between the first mounting hole 2 and the third mounting hole 4 and is connected with a fourth connecting hole 5, an end connecting component is provided inside the first mounting hole 2, and further the end connecting component includes a rectangular block 26 plugged into the inner wall of the first mounting hole 2, a sheathed cable 27 is plugged into the inner wall of the rectangular block 26, and the outer skin of the sheathed cable 27 is fixedly connected to the outer side of the rectangular block 26.

[0028] A further advantage of adopting the above method is that the terminal connection component is set as an integrated setting, which can not only facilitate the separation of the terminal connection component from the shell 1 when the shell 1 is damaged, thereby reducing the cost of replacing damaged parts, but also facilitate the removal of the shell 1 for direct repair during later maintenance.

[0029] It is worth noting that the sheathed cable 27 is a prior art and will not be described in detail here. The core of the sheathed cable 27 is inserted into the inside of the rectangular block 26, and the sheath is connected to the rectangular block 26 by hot-melt. The hot-melt technology is a prior art and will not be described in detail here.

[0030] A parallel connection component is provided inside the fourth connecting hole 5, and the parallel connection component further includes an upper pressure plate 28 inserted into the inner wall of the rectangular block 26 sink groove, the bottom support foot of the upper pressure plate 28 is fixed with a rubber pad, the top of the upper pressure plate 28 is fixed with a connecting frame 29, and the connecting frame 29 is inserted into the inner wall of the fourth connecting hole 5, and the top of the connecting frame 29 is fixed with an extension rod 30, and the top of the extension rod 30 is inserted into the inner wall of the top of the fourth connecting hole 5, and a second spring 31 is fixed between the inner bottom wall of the fourth connecting hole 5 and the lower surface of the connecting frame 29, and the parallel connection component also includes a slide plate 32 fixed to one end of the connecting frame 29, and the lower surface of the slide plate 32 is located in the same plane as the bottom of the inclined surface of the first inclined plate 14.

[0034] It is worth noting that a damping pad is fixed to the upper surface of the thickened plate 8 near one end of the connecting bolt 37 to increase the friction between the clamping plate 7 and the inner wall of the first plug-in slot 6 to prevent the cable body from being separated from the sheathed cable 27 due to external force.

[0035] The inner wall of the first plug-in slot 6 is hinged with a pressing wheel 9 through an axis, and the outer ends of the pressing wheel 9 are arranged in an arc surface, and the arc surface coincides with the inner wall of the clamping piece 7. An inner arc surface is provided at the center of the outer surface of the pressing wheel 9, and the inner arc surface coincides with the inner wall of the second mounting hole 3. The shell 1 is provided with a first alignment hole 10 at one end of the first plug-in slot 6, and a movable shaft 11 is inserted into the inner wall of the first alignment hole 10, and a beveled ring 12 is fixed to one end of the movable shaft 11.

[0036] A further benefit of adopting the above method is that the T-shaped plate 34 of the sliding assembly plays a limiting role, so that the clamping piece 7 can slide along a fixed direction.

[0037] A pipe 15 is fixed to the inner wall of the third mounting hole 4, and the inner cavity of the pipe 15 is connected to the first mounting hole 2 and the second mounting hole 3. A conveying channel 16 is provided inside the raised end of the pipe 15, and a separation pipe 17 is fixed to one end of the conveying channel 16 inside the cavity of the pipe 15. A second plug-in groove 18 is provided on the side of the pipe 15 between two adjacent conveying channels 16, and a split piece 19 is plugged into the second plug-in groove 18. A connecting hole 20 is provided in the middle of the pipe 15, and the connecting hole 20 is opened opposite to the conveying path 16, a telescopic frame 21 is inserted into the inner wall of the countersunk hole at the outer top end of the pipeline 15, and there are four telescopic frames 21.

[0038] When the present invention is used, Figure 2 As shown, one end of the wire is inserted from the inside of the second mounting hole 3. When the wire head is initially inserted, the clamping piece 7 is pushed toward the direction of the housing 1. When the thickening plate 8 contacts the first plug-in slot 6, it is pressed on the surface of the wire to facilitate the insertion of the wire. After the head of the wire is inserted into the second mounting hole 3, the bottom of the pressing wheel 9 is supported on the surface of the wire to facilitate the insertion of the wire. The top of the pressing wheel 9 is in contact with the inner wall of the clamping piece 7. When the head of the wire is pushed to the Figure 4 After the second plug-in slot 18 is located, the splitter 19 splits the outer skin of the wire into four parts, and then separates the wire skin from the wire core through the separation pipe 17. The wire skin is sent to the connecting hole 20 through the conveying channel 16, and the wire core is pushed along the pipe 15 until it is pushed to the Figure 2 The upper pressing plate 28 shown in the figure stops at the bottom, and the clamping piece 7 is pushed into the position as shown in the figure. Figure 5 The inner bottom wall of the connecting bolt 37 shown in the figure contacts the movable shaft 11 and squeezes the movable shaft 11, so that the alignment ramp 23 is squeezed by the bevel ring 12 and then drives the pressing plate 24 to squeeze the wire skin to fix the wire body. Before the wire skin is fixed, the first inclined plate 14 squeezes Figure 2 The slide plate 32 shown drives the upper pressing plate 28 to press down, thereby fixing the two wire cores together.
