A slot is opened at the position on the inner side of the arc frame 3 corresponding to the buckle 302, and the buckle 302 is engaged with the slot. The inner pad 301 improves the comfort of wearing the earphones. At the same time, the inner pad 301 can be removed from the inner side of the arc frame 3 for maintenance and replacement through the buckle 302, thereby improving the convenience of use of the shell connector.

[0028] Furthermore, adjustment bars 303 are installed at both ends of the arc frame 3. The top ends of the two sets of adjustment bars 303 are fixedly connected to the arc frame 3 by screws, and the bottom ends of the adjustment bars 303 are slidably connected to the adjustment sleeve 4. The adjustment bars 303 and the adjustment sleeve 4 at both ends of the arc frame 3 can be adjusted according to the head circumference, and the adjustment bars 303 can be separated from the arc frame 3 at the same time, so that when the wiring on the inside of the shell connector is damaged, it is convenient to check the fault point for repair and replacement.

[0029] Then, the top of the adapter 5 is rotatably connected to the connector 501, and the top of the connector 501 is fixedly connected to the shaft 502. The front and rear ends of the shaft 502 are rotatably connected to the adjustment sleeve 4. The adapter 5 can rotate the earphone shell 1 through the connector 501 to fit the outside of the head. At the same time, the two sets of earphone shells 1 can be folded toward the inside of the shell connector through the shaft 502, reducing the space occupied by the earphones for easy carrying.

[0030] Furthermore, the inner sides of the connector 501, the adapter 5, the adjustment sleeve 4 and the arc frame 3 are all provided with a wire threading groove 503, and the inner side of the wire threading groove 503 is provided with a wiring harness. The wiring harness comes out from the inside of the earphone shell 1, and then passes through the wire threading groove 503 into the inner side of the shell connector, thereby electrically connecting the two sets of earphone shells 1.

[0031] Secondly, in this embodiment, the specific structure of the quick release member 7 is as follows:

[0032] The quick-release part 7 includes a positioning sleeve 701, a positioning block 702, a mounting block 703, an extrusion block 704, a spring 705, a movable cavity 706 and a locking ball 707. The positioning sleeve 701 is slidably connected to the inner side of the connecting frame 6, the positioning block 702 is fixedly installed on the outer side of the positioning sleeve 701, the mounting block 703 is threadedly connected to the inner side of the positioning sleeve 701, the extrusion block 704 is slidably connected to the end of the positioning sleeve 701 away from the mounting block 703, the extrusion block 704 is fixedly connected to the top of the mounting block 703 by a spring 705, the movable cavity 706 is symmetrically opened on the left and right sides of the extrusion block 704, and the locking ball 707 is movably placed on the inner side of the movable cavity 706.

[0033] Finally, the positioning sleeve 701 is rotatably connected to the earphone shell cover 1. A positioning groove is provided on the outside of the earphone shell cover 1 to match the positioning block 702, and a locking groove 708 is provided inside the earphone shell cover 1 to match the card ball 707. When connecting and installing the earphone shell cover 1 and the connector body 2, after the connecting frame 6 is put on the outside of the earphone shell cover 1, the positioning sleeve 701 is inserted into the connection between the connecting frame 6 and the earphone shell cover 1, so that the positioning block 702 enters the inner side of the positioning groove and stops, and then the mounting block 703 is screwed toward the inner side of the positioning sleeve 701, driving the extrusion block 704 to move inward, thereby removing the card ball 707 from the connector body 2. The inner side of the movable cavity 706 is pushed out, so that the outer side of the card ball 707 is locked into the locking groove 708 to lock the positioning sleeve 701, thereby completing the connection between the connecting frame 6 and the earphone shell cover 1. The positioning sleeve 701 is rotatably connected to the earphone shell cover 1, so that the shell connector can swing to adjust the user's wearing position. When the wiring in the shell connector needs to be repaired or replaced, it is only necessary to rotate the mounting block 703 outward to retract the card ball 707 into the inside of the movable cavity 706, and then the positioning sleeve 701 can be taken out from the inner side of the connecting frame 6, so that the shell connector can be disassembled separately, thereby reducing the cost of using the earphones.

[0034] After the earphone shell cover 1 and the connector body 2 are connected, the connecting frame 6 is put on the outer side of the earphone shell cover 1, and the positioning sleeve 701 is inserted into the connection between the connecting frame 6 and the earphone shell cover 1, so that the positioning block 702 enters the inner side of the positioning groove and stops, and then the mounting block 703 is screwed toward the inner side of the positioning sleeve 701, driving the extrusion block 704 to move inward, thereby pushing the card ball 707 out from the inner side of the active cavity 706, so that the outer side of the card ball 707 is locked into the locking groove 708 to lock the positioning sleeve 701, thereby completing the connection between the connecting frame 6 and the earphone shell cover 1, and the positioning sleeve 701 is rotatably connected to the earphone shell cover 1, so that the shell connector can swing to adjust the wearing position of the user, and the adjustment bars 303 and the adjustment sleeve 4 at both ends of the arc frame 3 can be adjusted according to the head circumference. At the same time, the adjustment bar 303 and the arc frame 3 can be separated, so that when the wiring inside the shell connector is damaged, It is convenient to check the fault point for repair and replacement. The adapter 5 can rotate the earphone shell cover 1 through the connector 501 to fit the outside of the head. At the same time, the two sets of earphone shell covers 1 can be folded toward the inside of the shell connector through the rotating shaft 502, reducing the space occupied by the earphones and facilitating carrying. When the cable in the shell connector needs to be repaired or replaced, it is only necessary to rotate the mounting block 703 outward so that the card ball 707 is retracted into the inside of the movable cavity 706, and then the positioning sleeve 701 can be taken out from the inside of the connecting frame 6, so that the shell connector can be disassembled separately to facilitate the repair of the cable and the replacement of the shell connector separately. The whole operation process is simple and convenient. Compared with the existing shell connector for earphone assembly, the utility model can be disassembled separately to facilitate the repair of the cable and the replacement of the shell connector separately through design, thereby reducing the cost of using the earphone.
