Embodiment Construction

[0024] Such as Figure 1 to Figure 4 As shown, a trumpet-shaped plug wire protective sleeve includes a flower head 1, a corolla 2, and an opening 3 in the sheath.

[0025] The flower head 1 is hollow columnar, with protruding teeth 1a on the inner wall. The flower head 1 is used to wrap the plug tail 4, and the inner wall convex teeth 1a are embedded in the notch of the plug tail 5. The left end of the flower head 1 is connected with the plug 4, and the right end is connected with the corolla 2; the corolla 2 It is trumpet-shaped and made of elastic material. The axial section line of the corolla 2 is smooth and arc-shaped. The outer diameter of the corolla small opening 2b is smaller than the outer diameter of the flower head 1, and is smoothly transitioned to the right end of the flower head 1. The diameter of the inner wall of the corolla small opening 2a is Smaller in diameter than the inner wall of the flower head 1, it is used to wrap the wire 6 and connect with the inne...

Abstract

The invention discloses a petunia-shaped protection sleeve of a plug cord. The protection sleeve comprises a flower head, a corolla and a sheath opening. The flower head is in the shape of a hollow cylinder. Protruding teeth are arranged on the inner wall. The flower head is sued for wrapping a plug net tail. The protruding teeth on the inner wall are embedded into a recess of the plug net tail and are used for fixing the protection sleeve and preventing the protection sleeve from slipping. The corolla is in the shape of a horn. The external diameter of a corolla small opening is smaller than the external diameter of the flower head. The corolla is in smooth and transition connection with the right end of the flower head. The diameter of the inner wall of the corolla small opening is smaller than the inner wall of the flower head. The corolla small opening is used for wrapping wires and in stepped connection with the inner wall of the flower head. The sheath opening is a notch which is cut in half on the flower head and the left side of the corolla. Multiple paired buckling pieces are arranged along the notch and are used for connecting or opening the opening. The sheath opening can be a single-slit opening on the flower head and the left side of the corolla. The flower head is made of materials with quite high elasticity and intensity values so the flower head can directly clamp the plug net tail. According to the invention, a problem of proneness to break caused by bending and gathering of wires can be effectively solved; the protection sleeve is not likely to be lost and slip; and the protection sleeve with a decorative appearance is convenient to use.

Description

technical field [0001] The invention relates to the field of electronic wire protection, in particular to a protection for wires at the tail of a plug. Background technique [0002] The wire at the tail of the existing plug is generally protected by the plug tail, but at this time the bending of the wire is concentrated on the outer end of the plug tail, and the bending point of the wire is only moved to the outer end of the plug tail, which is easy Causes a break at the outer end of the plug tail. There are also some designs that hope to solve such problems, such as Chinese patent CN 105406273 A, which covers the entire plug in a side-mounted manner, making it less versatile, and makes the bending concentrated at the tail of the protective cover, without solving the problem of concentrated bending and Causes the problem of easy breakage. Chinese patent CN 205159636 U is a relatively good design, which is characterized in that the protective cover is placed on the tail of ...
