DETAILED DESCRIPTION

[0023] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0024] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0026] like Figures 1 to 4 As shown, a plug-in connection structure between an earphone head and an earphone cable is characterized in that it includes an earphone head body 1, a connecting column 2, a plug-in mechanism 3, a locking mechanism 4 and an earphone cable 5; the earphone head body 1 has a socket 6 at the lower end, the locking mechanism 4 has two symmetrically distributed ends connected to the socket 6, a plug-in connecting column 2 is provided in the socket 6, the plug-in mechanism 3 is located at the upper end of the connecting column 2, the connecting column 2 has an insulating ring 7 at the lower end, and one end of the earphone cable 5 passes through the insulating ring 7 to be electrically connected to the connecting column 2.

[0027] Specific as Figure 1 As shown, a sound receiving column 101 is connected to the inner side of the earphone head body 1, and a sound receiving earmuff 102 is sleeved on the sound receiving column 101. A signal converter 103 is connected to the lower end of the earphone head body 1, and the socket 6 is connected to the lower end of the signal converter 103. The socket 6, the sound receiving column 101 and the signal converter 103 are telecommunicationally connected. The sound receiving earmuff 102 is provided with a plurality of models, which can be replaced by being sleeved with the sound receiving column 101, so that the sound receiving earmuff 102 is more suitable for the user and more comfortable.

[0028] Specific as Figure 2 As shown, the plug-in mechanism 3 includes a plug-in protrusion 301 connected to the upper end of the connecting column 2, a positive pole column 302 and a negative pole column 303 connected to the upper end of the plug-in protrusion 301, a slot 304 cooperating with the plug-in protrusion 301 is provided in the socket 6, a positive hole 305 plug-fitting with the positive pole column 302 is provided in the slot 304, and a negative hole 306 plug-fitting with the negative pole column 303 is provided in the slot 304. During the plug-in process of the plug-in protrusion 301 and the slot 304, the positive pole column 302 should be aligned with the positive hole 305, and the negative pole column 303 should be aligned with the negative hole 306, so as to avoid affecting the normal use of the earphone due to incorrect connection of the positive and negative poles.

[0029] Furthermore, the two ends of the plug-in protrusion 301 are fixedly connected to the limiting blocks 307, and the inside of the slot 304 is provided with a limiting groove 308 that is plugged with the limiting block 307. The plug-in cooperation between the limiting block 307 and the limiting groove 308 makes the plug-in protrusion 301 and the slot 304 more tightly plugged and will not fall off easily.

[0030] Specific as Figure 3 and Figure 4As shown, the locking mechanism 4 includes a rotating seat 401, a rotating rod 402 and a locking plate 403. The rotating seat 401 is fixedly connected to the socket sleeve 6, and the locking plate 403 is fixedly sleeved on the rotating rod 402. One end of the rotating rod 402 is rotatably connected to the rotating seat 401. A locking screw 404 is fixedly connected to the connecting column 2, and a locking ring 405 is threadedly connected to the outer side of the locking screw 404. The locking plate 403 is provided with an embedding opening 406 that cooperates with the locking screw 404. Since the locking plate 403 is fixedly sleeved with the rotating rod 402, the rotation of the rotating rod 402 will inevitably drive the locking plate 403 to rotate downward until the embedding opening 406 of the locking plate 403 is embedded and connected with the locking screw 404. At this time, it is only necessary to rotate the locking ring 405 on the locking screw 404 so that the locking ring 405 presses the locking plate 403 to complete the locking.

[0031] In specific use, the headphone cable 5 is first plugged into the headphone head body 1, and the positive pole 302 on the plug-in protrusion 301 on the connecting column 2 is aligned with the positive pole hole 305 in the slot 304 on the socket 6. Similarly, the negative pole 303 on the plug-in protrusion 301 on the connecting column 2 is aligned with the positive pole hole 306 in the slot 304 on the socket 6, and the plug-in protrusion 301 is pushed into the slot 304 for plugging. At this time, the limit blocks 307 at both ends of the plug-in protrusion 301 are plugged into the limit grooves 308 in the slot 304, so that the entire connecting column 2 and the socket 6 are more tightly plugged and will not fall off easily.

[0032] At this time, start locking the connecting column 2 and the socket sleeve 6, rotate the rotating rod 402 at both ends of the socket sleeve 6, and the rotating rod 402 drives the locking plate 403 to rotate downward through the rotating connection with the rotating seat 401. The locking plate 403 is embedded and connected with the locking screw 404 through the embedding port 406, and then the locking ring 406 on the locking screw 404 is rotated to tighten the locking plate 403, thereby further strengthening the connection between the earphone head and the earphone cable to avoid the loss caused by the earphone head falling during use.

[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
