The crimping inclined surface 525 provided on the front of the wire-bonding cover body 521 can increase the tightness of the connection between the wire set and the electrical plug connector, reduce signal attenuation, and ensure signal transmission quality.

The above embodiments are only for explaining the technical concept and features of the present invention, and the purpose thereof is to let those familiar with the technology understand the contents of the present invention and implement them, and cannot limit the scope of protection of the present invention. All equivalent changes or modifications made should be covered in the protection scope of the present invention.
