In addition, the terms "first", "second" and "third" are only for the purpose of description, and cannot be understood as indicative or suggestive of relative importance.

[0017] As Figure 1 It is a structure schematic view of the protection sleeve for the automobile plug, and in the embodiment, the protection sleeve for the automobile plug comprises a protection sleeve body 1, the protection sleeve body 1 is composed of a plug sleeve 2 and a connecting sleeve 3, the connecting sleeve 3 is fixedly connected to the rear end of the plug sleeve 2, the connecting sleeve 3 is arranged to protect the connecting part of the connecting wire and the connector, an connector cavity 4 is formed in the front end of the plug sleeve 2, the plug sleeve 2 is used to protect the plug when being connected to the connecting piece, the inner wall of the connector cavity 4 is attached to the outer wall of the connecting piece, in order to ensure the attachment degree between them and prevent the gap, therefore, a sealing ring 6 is fixedly connected to the inner wall of the connector cavity 4, so as to increase the sealing effect, and an arc angle 7 is arranged on the front end surface of the plug sleeve 2, the structure design makes the connector cavity 4 present the shrinkage at the cavity opening of the plug sleeve 2 after injection molding, so as to increase the clamping capacity between the plug sleeve 2 and the connecting piece; the protection sleeve is arranged between the connecting wire and the connector, which can effectively prevent the damage caused by the collision and scraping between the plug and the connecting piece, and ensure the service life of the automobile plug. It is especially suitable for the protection of the male and female connectors.

[0018] In the embodiment, the connecting sleeve 3 is provided with a connecting hole 5, and the connecting hole 5 is communicated with the connector cavity 4, and the structure design facilitates the better connection between the connecting wire and the plug.

[0019] In the embodiment, the plug sleeve 2, the connecting sleeve 3 and the sealing ring 6 are designed in an integrated structure, which increases the connecting strength and improves the sealing performance.

[0020] In the embodiment, the sealing ring 6 is provided with a plurality of convexes on the surface, which increases the friction coefficient between the sealing ring 6 and the connecting member, and effectively avoids the possibility of the protective sleeve falling off during use.

[0021] The above is further detailed description of the utility model in combination with specific embodiments, and cannot be considered as limitation of the utility model to the description. For ordinary skilled in the art to which the utility model belongs, without departing from the concept of the utility model, a number of simple deductions or substitutions can be made, which should be considered as belonging to the protection scope determined by the claims of the utility model.
