Description

Technical Field

[0001] The present invention relates to a wire clip structure for wire harnesses, and particularly to a multi-strand wire harness device, its installation components and installation structure. Background Art

[0002] In the new energy vehicle industry, the types of wire clips for low-voltage wire harnesses are relatively sufficient. In the industry, commonly used wire clips for new energy vehicles include cable ties, clamps (R-type, P-type, D-type), hoop clamps, deformed types or plastic buckle-type plastic parts, which are suitable for low-voltage wire harnesses. With the rapid development of new energy vehicles and the increasing requirements and standards, wire harnesses are becoming larger. Currently, there are relatively few wire clips for fixing high-voltage wire harnesses with cross-sectional areas ranging from 70 square millimeters to over 135 square millimeters on the market. Most of them are fixed with cable ties, clamps, and hoop clamps, resulting in insecure fixing of the wire harness, with shaking phenomena. It is easy to loosen and fall off. After the rubber is damaged, the core of the clip is likely to cut the wire harness, and there is even a situation where the corrugated pipe is flattened. The wire harness arranged in this way is messy. When a bundle of wires is fixed, it is rather bulky. The D-type clamp does not achieve an insulating effect, and it is inconvenient for repair and disassembly. When wiring, several high-voltage wires in the same circuit are all bundled together. Since the high-voltage wires are relatively rigid, they will be in a mutually twisted state after being fixed. The wire harness arranged in this way is messy, without being horizontal and vertical, and has poor aesthetics. The irregular arrangement of the high-voltage wire harness also has a certain interference effect on the signal wires in the same area.

[0003] Basically, the main bodies of automotive high-voltage wire harness wire clips on the market are made of plastic. They are mainly installed by plastic deformation, fixed by plastic flipping buckles, and locked by bolts with plastic strips arranged side by side. Although such wire clips are relatively practical and greatly improve the overall layout of the routing and fixing of high-voltage wire harnesses and aesthetics, there are still corresponding problems. Either the fixing is too rigid, the installation is relatively slow, and the biggest problem is that in some places with small space and complex structures, there are limitations in use and it is difficult to operate. The semi-automatic deformation or buckle fixing with electricity has inconvenient disassembly, and it fails after multiple uses. Or it is directly buckled to death. After a long time, the plastic ribs used for the upper and lower connections break, and it is basically scrapped after being pulled out. Summary of the Invention

[0043] Furthermore, a protrusion for preventing loosening is provided on the second buckle opening 324. The protrusion can ensure that the second buckle assembly 32 is not easily loosened due to vibration, and the use structure is more stable.

[0044] As Figure 6 shown, the present invention also discloses a multi-strand wire harness device installation assembly, and multiple wire harness installation structures are detachably connected through a slot structure 4.

[0045] As Figure 4 、 Figure 5 、 Figure 6As shown, the card slot structure 4 includes a hook member 41 provided on one wire harness mounting structure and a splicing chute 42 provided on another wire harness mounting structure. The hook member 41 is detachably connected to the splicing chute 42.

[0047] Further, a reset hole 53 for pushing the roller in the roller screw 52 is provided near the roller screw 52 on the first main body 1. Such a design is mainly for: avoiding that the sliding groove positioning cannot be pushed in the case of a long time, and designing the reset hole 53 for resetting the top-opening wave bead.

[0048] The present invention also discloses a multi-strand wire harness device, which includes a wire harness 200, a fixed footrest 300 and the above-mentioned multi-strand wire harness device mounting assembly.
