Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In order to explain the technical solution of the present invention, the following description is made by using specific examples.

Examples

Referring to fig. 1 to 4, the present embodiment provides an audio connector, including a male plug, where the male plug is provided with a metal shell 1, one end of the male plug is a plug end 11, an upper surface of the plug end 11 is provided with a first groove 2, an 8PIN connection terminal 3 connected to the male plug is arranged in the first groove 2, a lower surface of the plug end 11 is provided with a second groove 4, both sides of the plug end 11 are provided with notches 5, the first groove 2, the second groove 4 and the notches 5 are filled with insulating plastic, and the other end of the male plug is a welding end 12.
