Description

Technical Field

[0001] This utility model relates to automotive wiring harness boxes, and in particular to wiring harness covers. Background Technology

[0002] Automotive wiring harness boxes house various electrical components such as relays and fuses, along with their wiring harnesses. For example, Chinese patent document CN217334951U discloses a wiring harness box comprising a body, an upper cover, and a lower cover. The upper cover protects the electrical components, while the lower cover accommodates the wiring harness. A wire-passing hole is provided on the side of the lower cover for the wiring harness to pass through. The wiring harness box body and the lower cover are fastened together by protrusions and latches. When the length-to-width ratio of the wiring harness box body is large, the latching area between the latch and the protrusion is small, resulting in low strength of the latching structure. The edges of the lower cover away from the latching structure are prone to deformation, creating gaps with the body and resulting in poor sealing. Furthermore, the wiring harnesses near the passing holes are denser and occupy more space, while those further away are sparser and occupy less space. If a regular rectangular flat-bottomed lower cover is used, the depth of the original lower cover cannot match the wiring harness routing, wasting some of the lower cover space. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies where low snap-fit ​​structure strength causes deformation of the lower cover edge, resulting in gaps and thus poor sealing, a tongue extending from the side wall is proposed to increase snap-fit ​​strength and improve the sealing performance of the wire harness cover. Furthermore, an inclined bottom wall structure is proposed to adapt to the wire harness orientation and improve the space utilization of the wire harness cover.

[0004] The technical solution is: a wire harness cover, which is formed by side walls, end walls and door walls to form a rectangular cover body. The cover body is connected to the bottom wall. The door wall has a notch. A tongue extends from the middle of the edge of the side wall. The bottom wall is inclined from the end wall to the door wall. The notch in the door wall is connected to the wire groove.

[0005] Based on the technical solution, the wire harness cover is embedded into the inner side of the box via a tongue. The inner side of the box clamps the tongue to prevent deformation of the side wall, ensuring that the side wall remains straight and tightly fits the edge of the box. There is no gap between the wire harness cover and the box, which improves the sealing performance of the wire harness cover. At the same time, the internal space of the bottom wall near the end wall is relatively narrow, while the internal space of the bottom wall near the door wall is relatively spacious. The sloping bottom wall is just right to match the wire harness direction and the sparseness of the wire harness, effectively improving the space utilization of the wire harness cover.

[0009] To better understand the purpose, features, and advantages of this utility model, the following description, in conjunction with the accompanying drawings and embodiments, will further illustrate this utility model.

[0010] like Figure 1 As shown, the wire harness cover is integrally molded. The wire harness cover 2 has a side wall 2.1, an end wall 2.2, a bottom wall 2.3, a wire groove 2.4, and a door wall 2.9. The two opposite side walls 2.1 and end walls 2.2 and the door wall 2.9 form the cover body. The cover body is rectangular. The side walls are the long sides of the rectangular cover body, and the end walls and door walls are the wide sides of the rectangular cover body. The length of the side wall 2.1 is more than twice the length of the end wall.

[0011] A tongue 2.6 extends from the middle of the edge of sidewall 2.1, and the length of tongue 2.6 is approximately one-third the length of sidewall 2.1. The main body of the cover connects to the bottom wall. The height of end wall 2.2 is lower than the height of door wall 2.9. The bottom wall is inclined, with the inclination direction from end wall 2.2 to door wall 2.9. Door wall 2.9 has a notch 2.5 for wire harnesses to pass through. Notch 2.5 connects to wire groove 2.4, and the cross-section of the wire groove is approximately semi-circular. Ear plates 2.7 and corner plates 2.8 extend from the four right angles of the main body of the cover. One leg of ear plate 2.7 connects to corner plate 2.8.

[0012] The wire harness box body 1 and wire harness cover 2 are fastened together by ear plates 2.7 and corner plates 2.8. The tongue 2.6 of the side wall 2.1 of the wire harness cover 2 is embedded into the inner side of the body 1. The length of the tongue 2.6 is more than three times the length of the ear plate 2.7. The tongue serves to strengthen the side wall, making the side wall of the wire harness cover fit tightly against the edge of the box body. The main body of the wire harness cover stores the wire harness, and the bottom wall of the wire harness cover guides the wire harness to be stored along the inclined direction of the bottom wall. The wire harness is led out of the box body from the wire groove.

Claims

1. A wire harness cover, comprising a rectangular cover body formed by side walls, end walls, and a door wall, wherein the cover body is connected to a bottom wall, and the door wall has an opening, characterized in that: A tongue extends from the middle of the edge of the sidewall, the bottom wall slopes from the end wall to the door wall, and the notch in the door wall is connected to a groove.
