Description

Technical Field

[0001] The utility model relates to a buckle structure, in particular to a wire harness buckle structure. Background Art

[0002] With the popularization of sunroof technology, there are more and more functional components on the sunroof, among which more electrical wiring harnesses need to be connected front and back. There are two specific ways to connect the traditional electrical wiring harnesses. One is to directly use nails to fasten them to the mechanical group rails, which requires the mechanical group rails to be processed with fastening holes. The structures of the racks, sliders and other structures in the mechanical group are relatively complex, and the design and processing of the fastening holes are extremely difficult, which increases the production cost. The second is to directly use adhesive strips to bond them to the side frame of the sunroof or the outside of the mechanical group rails. Their stability is poor, and they are easy to loosen and fall off after long-term use, affecting the overall electrical safety of the sunroof. Summary of the invention

[0003] The utility model provides a wire harness buckle structure which has a simple structure and takes into account both convenient production of skylights and stable buckling of wire harnesses.

[0004] The technical solution adopted by the utility model is: a wire harness buckle structure, characterized in that: it includes an upper clamping part, an intermediate connecting part and a lower buckle part, an elastically opened and closed clamping groove is arranged on the inner side of the upper clamping part, the clamping groove is clamped on the horizontal edge of the outer side of the mechanical group guide rail, the upper clamping part is downwardly connected to the lower buckle part through the intermediate connecting part, the lower buckle part is a buckle plate along the front and rear direction of the mechanical group guide rail, the buckle plate faces the mechanical group guide rail, and more than two buckle belts are wrapped around the front and rear of the buckle plate to tighten the wire harness to fit on the buckle plate.

[0005] More than one hook is arranged on the upper slot wall and / or the lower slot wall in the snap-in slot, and a snap slot corresponding to the hook is arranged on the horizontal edge.

[0006] The hooks are arranged horizontally in an offset manner on the upper and lower notch walls in the engaging groove.

[0007] The buckle plate is an arc-shaped panel structure that fits the wiring harness in an inward arc.

[0008] The side of the arc panel close to the mechanical group guide rail is higher than the lowest point of the arc panel.

[0009] More than one reinforcing rib is arranged on the outer side of the upper clamping portion.

[0010] One or more reinforcing ribs are arranged on the inner side and / or the outer side of the intermediate connecting portion.

[0011] The beneficial effects achieved by the utility model are:

[0012] 1. According to the guide rail structure of the mechanical group, the upper clamping part of the bayonet is clamped on the horizontal edge of its outer side, and the lower part is hung under the middle connecting part. The lower buckle part is a front-to-back structure and fits the wire harness inwardly and is fastened by the buckle belt. It can fasten the wire harness quickly, stably and firmly, and avoid affecting the operation and stability of the guide rail, rack, slider and other structures in the guide rail of the mechanical group, which is conducive to the fast, safe and stable buckle of the wire harness.

[0013] 2. The hook in the snap-fit ​​groove of the upper snap-fit ​​part cooperates with the snap-fit ​​opening on the horizontal edge to further improve the stability and firm snap-fit ​​of the snap-fit ​​structure.

[0014] 3. The lower buckle part adopts an arc-shaped panel to fit the wire harness, which can effectively restrain and protect the wire harness and prevent deformation and loosening of the wire harness. At the same time, the inner edge of the arc-shaped panel is higher than its lowest point. The arc-shaped panel at the lowest point has a supporting effect on the wire harness, further preventing deformation and loosening of the wire harness. BRIEF DESCRIPTION OF THE DRAWINGS
