The left end of the first spring block 232 moves toward the groove cavity direction of the limiting groove 2 114 under the guidance of the arc surface of the annular guide block 113, so that the first spring block 232 moves from the right end opening of the groove cavity of the limiting groove 2 114 to the left end of the groove cavity of the limiting groove 2 114, so that the first spring block 232 is in the groove cavity of the limiting groove 2 114, thereby increasing the strength of the reinforcing block 110. When the audio plug is used, one end of the wire 100 is not easy to break, thereby preventing the wire body inside the wire 100 from breaking.

[0030] By disposing the first elastic block 232 , the strength of the reinforcing block 110 is increased, and the connection between the right end of the electric wire 100 and the insulating member 220 is reinforced.

When the connecting wire 001 and the audio connector 002 are fixedly connected, the right end of the wire 100 moves into the left hole cavity of the shielding layer 230, so that the right end of the reinforcing block 110 is inserted into the left hole cavity of the shielding layer 230.

[0033] An annular guide block 113 for guiding the first spring block 232 is installed on the left side of the groove cavity of the annular groove 111, and one end of the annular guide block 113 is arranged in an arc-shaped surface. When the left end of the first spring block 232 contacts the upper end of the arc-shaped surface of the annular guide block 113, the first spring block 232 is guided, so that when the wire 100 approaches the insulating member 220, the left end of the first spring block 232 slides into the groove cavity of the second limiting groove 114 under the guidance of the annular guide block 113. A plurality of second limiting grooves 114 are provided at the lower end of the groove cavity of the annular groove 111, and the first spring block 232 is extended and retracted in the groove cavity of the second limiting groove 114.

Specifically, one end of the insulating member 220 is arranged at the rear end of the protective shell 210, and the other end extends away from the protective shell 210, so that the insulating member 220 covers the rear end of the plug 200.

[0035] The shielding layer 230 is installed on the outside of the insulating member 220. The shielding layer 230 is set as a conductive coating, and the conductive coating is conductive paint. The shielding layer 230 solves the problem that the existing injection plug transmission is easily interfered, thereby effectively improving the quality of the injection plug signal transmission. The shielding layer 230 is installed inside with a protrusion 231, a first elastic block 232 and a second elastic block 233 for cooperating with the reinforcement block 110 to protect the wire 100.

[0036] The first spring block 232 is an L-shaped elastic block, the second spring block 233 is a V-shaped elastic block, the protrusion 231 is fixedly mounted on the inner wall of the left hole of the shielding layer 230, and the right end of the first spring block 232 is fixedly mounted on the right end of the protrusion 231, one end of the second spring block 233 is fixedly mounted on the left side of the protrusion 231, and the other end of the second spring block 233 is fixedly mounted on the first spring block 232. When the first spring block 232 is inserted into the annular guide block 113, under the guidance of the arc surface of the annular guide block 113, the first spring block 232 is driven 32 undergoes elastic deformation, causing the first spring block 232 to slide into the groove cavity of the second limiting groove 114, and when the first spring block 232 undergoes elastic deformation, the first spring block 232 moves away from the protrusion 231 and pulls the second spring block 233, causing the second spring block 233 to undergo elastic deformation and pull the first spring block 232, so that the second spring block 233 can stabilize the first spring block 232. A shell 240 is installed on the outside of the shielding layer 230, and the shell 240 covers the outside of the shielding layer 230 for protection.
