Embodiment 1

[0021] see Figure 1-Figure 3 , the sleeve body 1 of the plug sleeve is set in a circular shape, and three sleeve grooves 2 are evenly arranged on it, and the angle between each sleeve groove 2 is 120 degrees. The shape is an inverted trapezoid, and the ribs are provided with rib holes 31 and 311 that are interference fit with the ends of the pins of the plug. The upper end surface, and at the junction of the upper and lower end surfaces, chamfer a 21 and chamfer b 22 are provided.

Embodiment 2

[0022] Embodiment 2: see Figure 4 , The cross-sectional shape of the groove bar is V-shaped, and the others are the same as in Embodiment 1.

[0023] Plug sleeve use process:

[0024] In daily life, the user can match the used plug with the plug sleeve of the present invention, which can effectively protect the pins of the plug on the one hand and decorate the plug on the other hand;

Abstract

The invention relates to a power plug sheath, in particular to a power plug sheath with larger clamping force. The power plug sheath comprises a sheath body, wherein a sheath groove is arranged on the sheath body. The closed end of the sheath groove is provided with a groove rib for generating the clamping force, and a groove rib hole is formed in the middle of the groove rib. The groove rib hole is in interference fit with a pin of a power plug, so that the larger clamping force can be provided. The clamping force provided by the plug sheath is slightly smaller after the plug sheath is used for a span, but the fact that the pin of the power plug is fixed into the plug sheath can still be effectively ensured.

Description

technical field [0001] The invention belongs to the field of a power plug cover for household use and similar purposes, and in particular relates to a plug cover with relatively large clamping force. Background technique [0002] In the prior art, the power plug cover is mostly a body, on which a quadrangular body is connected, and there is a cavity inside, but there is no further component to provide clamping force in the cavity. When used for the first time, the existing power plug sleeve can provide a certain holding force. After a period of use, the clamping force decreases or disappears, affecting normal use and other technical problems. Contents of the invention [0003] The problem to be solved by the present invention is to provide a power plug sleeve with a relatively large clamping force. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A power plug sleeve is compo...
