Detailed implementation manners

[0027] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0028] A high-sealing audio equipment wiring head, as Figures 1-4 shown, includes a locking sleeve 1, a connecting sleeve 2, a connecting plug 3, a connecting end 4, a conductive column 41, a wire harness sealing structure and a joint sealing structure. An external thread is provided on the right side of the connecting sleeve 2, and the locking sleeve 1 is connected to the right side of the connecting sleeve 2 through the external thread. Four L-shaped grooves 21 are evenly spaced along the circumferential direction inside the connecting sleeve 2, and a connecting plug 3 is slidably connected between the four L-shaped grooves 21. The connecting plug 3 can slide along the L-shaped groove 21. The middle of the right side of the connecting plug 3 is connected to a connecting end 4, and four conductive columns 41 are evenly spaced along the circumferential direction on the connecting end 4. A wire harness sealing structure for sealing the wire harness is provided on the locking sleeve 1, and a joint sealing structure for sealing the joint is provided on the connecting plug 3.

[0029] As Figure 2 and Figure 3As shown, the wire harness sealing structure includes a rubber sealing ring 52, a liquid storage sleeve ring 53, a piston ring 54, a first elastic member 55, and an extrusion ring 56. Four liquid delivery channels 51 are evenly spaced along the circumferential direction on the right side of the locking sleeve 1. The right side of the locking sleeve 1 is tapered. The right side of the locking sleeve 1 is connected with a rubber sealing ring 52. One end of the liquid delivery channel 51 communicates with the inner side of the rubber sealing ring 52. The inner right side of the locking sleeve 1 is connected with a liquid storage sleeve ring 53. The inside of the liquid storage sleeve ring 53 stores liquid. Four liquid outlet holes are evenly spaced on the right side of the liquid storage sleeve ring 53. The liquid outlet holes are aligned with the liquid delivery channels 51. A piston ring 54 is slidably connected inside the liquid storage sleeve ring 53. A first elastic member 55 is connected between the piston ring 54 and the liquid storage sleeve ring 53. The first elastic member 55 is a return spring. The left side of the piston ring 54 passes through the liquid storage sleeve ring 53 and is connected with an extrusion ring 56. During the process of screwing the locking sleeve 1 into the connecting sleeve 2 through threads, the connecting sleeve 2 will contact the extrusion ring 56 and push the extrusion ring 56 to move.

[0030] As Figure 2 and Figure 4 shown, the joint sealing structure includes a rotating ring 61, contact balls 62, a second elastic member 64, and an elastic sealing ring 65. An annular groove is provided on the connecting plug 3. A rotating ring 61 is arranged inside the annular groove. A plurality of contact balls 62 are evenly spaced and connected to the right side of the rotating ring 61. The rotating ring 61 can slide and rotate inside the annular groove. A second elastic member 64 is connected between the rotating ring 61 and the annular groove. The second elastic member 64 is a compression spring. A plurality of grooves adapted to the contact balls 62 are evenly spaced on the right side wall of the annular groove. The number of grooves is the same as the number of contact balls 62. In the initial state, the contact balls 62 are stuck in the grooves. A liquid storage channel 63 is provided on the left side inside the connecting plug 3. An elastic sealing ring 65 is connected to the left side inside the connecting plug 3. One end of the liquid storage channel 63 communicates with the inside of the elastic sealing ring 65. The left side of the rotating ring 61 is located inside the liquid storage channel 63. The liquid storage channel 63 stores liquid so that when the rotating ring 61 slides, it can squeeze the liquid inside the liquid storage channel 63 and squeeze the liquid into the elastic sealing ring 65, causing the elastic sealing ring 65 to expand.

[0031] When the audio equipment needs to be connected, this wiring head can be used. When in use, first put the locking sleeve 1 on the connecting wire 100, and then push the connecting plug 3 to move to the right, so that the connecting plug 3 passes through the right side of the connecting sleeve 2. At this time, the connecting wire 100 can be separated and put on the conductive column 41, thus completing the connection between the connecting wire 100 and the connecting end 4. Then pull the connecting plug 3 to move to the left. When the connecting plug 3 moves to the leftmost limit, then operate the connecting plug 3 to rotate along the L-shaped groove 21, so that the connecting plug 3 is stuck at the connecting sleeve 2. Then screw the locking sleeve 1 onto the connecting sleeve 2. During the fixing process, the connecting sleeve 2 will contact and push the extrusion ring 56 to move. When the extrusion ring 56 moves, it can drive the piston ring 54 to move, and the first elastic member 55 is stretched. When the piston ring 54 moves, it can push the liquid in the liquid storage sleeve ring 53, and squeeze the liquid through the liquid delivery channel 51 into the rubber sealing ring 52, so that the rubber sealing ring 52 expands and abuts against the connecting wire 100, thereby sealing the connecting wire 100. Then operate the rotating ring 61 to rotate. When the rotating ring 61 rotates, the contact ball 62 squeezes the groove, and then the contact ball 62 is pushed by the groove to move to the left. When the contact ball 62 moves, it can drive the rotating ring 61 to move, and the second elastic member 64 is compressed. When the rotating ring 61 moves, it can squeeze the liquid in the liquid storage channel 63, so that the liquid in the liquid storage channel 63 enters the elastic sealing ring 65, and the elastic sealing ring 65 expands and abuts against the female plug 200, thereby sealing the connection between the female plug 200 and the connecting plug 3. In this way, this wiring head can be used to connect the audio equipment, and after the connection is completed, the rubber sealing ring 52 and the elastic sealing ring 65 can expand for sealing treatment, ensuring the tightness inside the wiring head and avoiding the situation that the internal circuit of the wiring head is damaged due to dust or water entering.

[0032] As Figures 5-7 shown, it further includes a clamping plate 71 and a third elastic member 72. Four clamping plates 71 are slidably connected to the connecting end 4 at equal intervals along the circumferential direction. The clamping plate 71 is slidably connected to the conductive column 41. After the connecting wire 100 is put on the conductive column 41, the clamping plate 71 can press the connecting wire 100. A third elastic member 72 is connected between the clamping plate 71 and the connecting end 4, and the third elastic member 72 is a compression spring.

[0033] As Figure 8 shown, it further includes an extrusion column 81 and a wedge block 82. An extrusion column 81 is connected to each clamping plate 71. A plurality of wedge blocks 82 are evenly spaced and connected to the left side inside the connecting sleeve 2, and the wedge blocks 82 are located on the moving track of the extrusion column 81.

[0034] When connecting the connecting wire 100 to the conductive post 41, the clamping plate 71 can be first pulled to slide, and the third elastic member 72 is compressed. Subsequently, the connecting wire 100 can be connected to the conductive post 41. Then, the clamping plate 71 is released. Under the action of the third elastic member 72, the clamping plate 71 resets and can clamp the connecting wire 100, fixing the connecting wire 100 and the conductive post 41 together. Subsequently, when the connecting plug 3 rotates along the L-shaped groove 21, the pressing post 81 will also rotate together. When the pressing post 81 rotates, it will contact the wedge block 82. When the pressing post 81 contacts the wedge block 82, it will be squeezed by the wedge block 82, so that the pressing post 81 moves towards the connecting wire 100. When the pressing post 81 moves, it can drive the clamping plate 71 to move, so that the clamping plate 71 clamps the connecting wire 100, assisting in fixing the connecting wire 100. In this way, after the connecting wire 100 is connected, the connecting wire 100 can be fixed, making the connection of the connecting wire 100 more stable and avoiding the loosening of the connecting wire 100.

[0035] As Figures 9-11 shown, it further includes a wedge-shaped ring 91 and a sealing sleeve ring 92. The left side inside the connecting sleeve 2 is connected with a wedge-shaped ring 91, and the right side of the connecting plug 3 is connected with a sealing sleeve ring 92. The left side of the sealing sleeve ring 92 is provided with a clamping groove adapted to the wedge-shaped ring 91, so that the wedge-shaped ring 91 can be clamped at the sealing sleeve ring 92. When the connecting plug 3 moves to the leftmost side inside the connecting sleeve 2, the wedge-shaped ring 91 can be clamped at the sealing sleeve ring 92. Through the wedge-shaped ring 91 and the sealing sleeve ring 92, the gap between the connecting sleeve 2 and the connecting plug 3 can be sealed, preventing water from entering the terminal head through the gap, and thus further sealing the internal structure of the terminal head.

[0036] As Figures 9-11 shown, it further includes a U-shaped sealing gasket 10. The right side of the connecting plug 3 is connected with a U-shaped sealing gasket 10. When the connecting plug 3 and the connecting sleeve 2 fit, the U-shaped sealing gasket 10 can resist against the connecting sleeve 2. Cooperating with the wedge-shaped ring 91 and the sealing sleeve ring 92, it can further seal the contact part between the connecting plug 3 and the connecting sleeve 2 and improve the sealing effect.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
