A cable seal for an alternating current charging vehicle

Abstract

The invention relates to a cable seal for an alternating current charging vehicle comprising a seal body (1), a cable sealing hole (2) is arranged in the seal body (1), the inner surface of the cablesealing hole (2) is provided with a plurality of spaced-apart circular arc-shaped sealing ribs (3), The vertical distance D=0. 25-0.35 mm between the apex of the circular arc-shaped sealing rib (3) and the inner surface of the cable sealing hole (2), and the included angle b=84-86 DEG C between two tangent lines passing through the intersection of the circular arc-shaped sealing rib (3) and the inner surface of the cable sealing hole. The cable seal for an alternating current charging vehicle can reduce the maintenance cost of the mould, improves the production efficiency and enhance the sealing protection grade; and reduces the frictional resistance of the seal rib of the seal to the outer insulator of the cable when the cable is inserted.

Description

technical field [0001] The invention belongs to the technical field of sealing and relates to a sealing member, in particular to a cable sealing member of an AC charging vehicle. Background technique [0002] In new energy vehicles, that is, electric vehicles, AC charging vehicle cables are used and matching seals are required. [0003] Existing AC charging vehicle cable seals such as figure 1 As shown, it includes a body, a cable sealing hole in the body, and a sealing rib in the cable sealing hole. In the existing AC charging vehicle cable seal, the sealing rib is zigzag and high in height. Specifically, such as figure 1 As shown, the height d of the sealing rib is 0.57mm, and the included angle a of the zigzag is an acute angle and a=56°. [0004] Due to the zigzag shape and high height of the sealing rib, the cable sealing hole of the existing AC charging vehicle cable seal is likely to cause the sealing rib to break and the mold core to break during the production p...

AI Technical Summary

Problems solved by technology

[0004] Due to the zigzag shape and high height of the sealing rib, the cable sealing hole of the existing AC charging vehicle cable seal is easy to cause the sealing rib to break and the mold core to break during the production process, and the production efficiency and pass rate are very low.

At the same time, due to the blocking of the seal, the customer has a large threading resistance when installing the cable, low assembly efficiency and poor sealing and waterproof effect
