Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that those skilled in the art can make various changes or modifications to the utility model after reading the content taught by the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

As shown in Figures 1-4, the embodiment of the present invention relates to a waterproof audio and video connection plug, including a plug body 1, a boot 2 and a button 4, and one end of the plug body 1 is sleeved with a boot 2, The middle part of the other end is embedded with a plug insulator 5, the upper end surface of the plug body 1 on the upper side of the plug insulator 5 is arranged with a groove 8, and a through hole is axially opened on the plug body 1 on the upper side of the plug insulator 5 11. The groove 8 and the through hole 11 are connected by a guide groove 10 arranged in the axial direction. The button 4 includes a pressing part 12, a buckle part 7 horizontally connected to one end of the pressing part 12, and a buckle with the buckle. The plug insertion part 6 connected to one end of the part 7, the pressing part 12 and the buckle part 7 are respectively placed in the groove 8 and the guide groove 10, and the plug insertion part 6 is inserted into the through hole 11 Internal fixation.

The most important feature of this patent application is to place the button 4 in a closed space surrounded by the groove 8, the guide groove 10 and the through hole 11. This closed space is completely isolated from the inner space of the plug body 1, and the outside The water cannot enter into the plug insulator 5;

Since a part of the button 4 is movable, the opening of the groove 8 faces upwards. In order to better fix the button 4, a through hole 11 connected with the end face is provided on the upper end of the plug body 1, and the button 4 is inserted through the plug. The connecting portion 6 is inserted into the through hole 11 to be fixed, so that the through hole 11 is also blocked, and moisture cannot enter the insertion end surface of the plug.

The buckle part 7 on the button 4 is exposed to the outside for interlocking with the corresponding connector male head or audio and video socket. As long as the pressing part 12 is pressed down, the connecting plug can be pulled out.

As a supplement of the present utility model, a circular groove 9 is arranged at the position where the groove 8 and the guide groove 10 are connected and transitioned, and the reset button with the upper end and the lower end surface of the pressing part 12 is embedded in the circular groove 9. The length of the spring 13 and the return spring 13 is relatively short, mainly to provide a restoring force for the reset of the button 4. If the materials of the buckle part 7 and the plug insertion part 6 have certain elasticity, it can be realized without installing the return spring 13 Automatic return of the pressing part 12 after being pressed.

As a preference, one end of the plug insertion part 6 is a cylindrical plug 61 whose shape and size match the through hole 11. The end face of the cylindrical plug 61 is flush with the end face of the plug body 1, and the cylindrical plug 61 is integrally formed with the plug insertion part 6, and can also be installed in the through hole 11 in advance, and then one end of the plug insertion part 6 and the cylindrical plug 61 withstand.

For further optimization, the cylindrical plug 61 can also be integrally formed with the plug body 1, that is to say, the through hole 11 cannot be seen on the end face of the plug body 1, and the through hole 11 becomes an inner hole with one end closed, and the plug insertion part 6 can be directly inserted into the through hole 11, and the waterproof effect of such a structure is better.

As a preference, one end of the buckle part 7 is pressed against one end of the through hole 11 and an inclined protrusion is arranged on the upper end surface. When the pressing part 12 is in a free state, the height of the inclined protrusion is higher than the upper end surface of the plug body 1. , so that when the plug is inserted, the bevel protrusion can be embedded in the corresponding groove of the socket or the male head and fixed.

Preferably, the shape of the pressing portion 12 matches the shape of the groove 8. For the sake of aesthetics, the pressing portion 12 is made in an oval shape, and the upper end surface is an arc-shaped arched surface, in order to increase the contact area between the pressing portion 12 and the fingers. , to improve the comfort of pressing, the shape of the groove 8 is the same as that of the pressing part 12, but the size is slightly larger, and the smaller the gap between the two, the better.

As a preference, inside the boot 2 is axially arranged a cylindrical wire clamp claw 3 whose end is inserted into the plug body 1 .

The utility model has a simple structure. The key is placed in the groove, and the through hole is blocked by the plug plug to form a closed space that is not connected to the inside, which effectively realizes the waterproof of the key, and the waterproof effect is good, which can reach the national authority. The tested dustproof level is 6, and the waterproof level is 7.
