Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

Example 1:

as shown in fig. 1 to 8, the audio connector of the present embodiment includes a housing 1 and an explosion-proof mechanism 2; the explosion-proof mechanism 2 is arranged on the shell 1, in the embodiment, the shell 1 is a linear shell structure, and the explosion-proof mechanism 2 comprises a contact 2a, an inner mandrel 2b, a connecting piece 2c, a trigger piece 2d, a reset component 2e and a mounting seat 2 h; the mounting seat 2h is arranged on one end of the shell 1; the contact 2a is arranged on one side of the mounting seat 2 h; the inner core shaft 2b is arranged on the contact 2a along the axial direction of the shell 1, one end of the inner core shaft 2b is fixedly connected with the contact 2a, and the inner core shaft 2b penetrates through the mounting seat 2 h; the trigger piece 2d is arranged in the mounting seat 2h in a slidable manner along the length direction of the shell 1; the connecting piece 2c is fixedly arranged on the inner mandrel 2 b; the reset component 2e is arranged in the mounting seat 2h, and two ends of the reset component 2e are respectively and fixedly connected with the trigger component 2d and the mounting seat 2 h; the application of mount pad 2h for cylindric structure, mount pad 2h sets up on shell 1, and one side that shell 1 was kept away from to mount pad 2h begins to have the holding tank, and reset assembly 2e sets up in the holding tank, and the holding tank is the cylinder structure, and the axis of holding tank and shell 1's axis collineation trigger piece 2d slidable sets up in the holding tank.

Specifically, in the initial state, the initial state here refers to a state in which the connecting member 2c fixedly provided on the inner core shaft 2b and the trigger 2d are in contact with each other when the audio connector has not been inserted into the audio, because the trigger 2d is slidably provided on the mount 2h and the housing 1 are in contact with each other. Therefore, when a user inserts the audio connector into the sound, the residual current in the sound contacts with the contact 2a, so that the current is transmitted to the inner core shaft 2b through the contact 2a, the end of the inner core shaft 2b, which is far away from the contact 2a, is connected with the equipment, but because the connecting piece 2c is connected with the trigger piece 2d and the connecting piece 2c is connected with the mounting seat 2h, the current is transmitted to the trigger piece 2d through the connecting piece 2c, then transmitted to the mounting seat 2h through the trigger piece 2d, and then transmitted to the shell 1 through the mounting seat 2h, so that the plug is in a grounding state in the process of inserting the sound, the residual current in the sound cannot be transmitted to the equipment through the inner core shaft 2b, and thus the situation that the sound popping sound does not occur when the audio connector is inserted into the sound can be ensured, at this time, the sound pushes the trigger 2d into the receiving groove of the mounting seat 2h, so that the trigger 2d is separated from the connecting member 2 c. Since the connecting piece 2c and the triggering piece 2d are separated, the inner mandrel 2b which is originally in the grounding state is not grounded, current flows into the inner mandrel 2b after passing through the contact 2a, and the connecting piece 2c arranged on the inner mandrel 2b is in the open circuit state because the connecting piece 2c is not in contact with the triggering piece 2d, so that the current can only be transmitted to the equipment from the inner mandrel 2b, and the equipment is in the closed state. After using, only need this moment with the audio frequency connect from the stereo set take out can, reset subassembly 2e this moment can reset trigger piece 2d, will make trigger piece 2d contact with connecting piece 2c once more like this, when using the audio frequency plug next time, remaining electric current in the stereo set just can be triggered 2d and guide ground connection just like this to guaranteed when the use next time, the condition of explosive sound still can not appear. So just realized under the normal use that does not influence audio frequency and connect, can also make audio frequency connect when inserting the stereo set, the technical requirement of the phenomenon of the crackle can not appear in the stereo set.

As shown in fig. 5, the return assembly 2e includes a spring 2e 1; two ends of the spring 2e1 are respectively fixedly connected with the mounting seat 2h and the trigger piece 2 d; in this embodiment, when the spring 2e1 is in an initial state, that is, when the audio connector is not connected to the audio device, the spring 2e1 is in an uncompressed state, when the audio plug is inserted into the audio device, the audio device will lower the trigger 2d on the mounting base 2h, the trigger 2d will gradually leave the connecting part 2c under the urging of the audio device, at this time, the connecting part 2c and the trigger 2d will be in an open state, at this time, the spring 2e1 located between the trigger 2d and the mounting base 2h will also be in a compressed state, the elastic force of the spring 2e1 is not too large, otherwise, after the audio plug is inserted into the audio device, the resilience of the spring 2e1 will eject the audio plug from the audio device, which will affect the normal use of the audio plug. After the use, pull out the back with the audio frequency plug from the stereo set this moment, because trigger piece 2d is not being restricted by the stereo set, spring 2e1 just can not be restricted like this, and spring 2e1 drives trigger piece 2d under the effect of self resilience power and resets, and trigger piece 2d after resetting can contact with connecting piece 2c once more, and when using next time like this, when audio frequency connects and inserts the stereo set, the phenomenon of popping sound just can not take place for the audio frequency joint. This achieves the technical requirement of the reset element 2e that it can reset the trigger element 2 d.

As shown in fig. 4-6, the explosion-proof mechanism 2 further comprises an anti-creeping mechanism; the anti-creeping mechanism is arranged on the inner mandrel 2b and comprises a protective sleeve 2g1 and an isolation layer 2g 2; the insulating layer 2g2 is fixedly arranged on the outer wall of the inner mandrel 2 b; the protective sheath 2g1 is fixedly disposed on the outer wall of the insulating layer 2g2, and the insulating layer 2g2 is an insulating material in this application. When the audio connector is inserted into the sound, the residual current in the sound can only enter the inner core from the contact 2a, the influence of the sound on the current transmission of the inner core shaft 2b can be prevented by arranging the isolation layer 2g2 and the protection layer, and the condition that the current overflows when the inner core shaft 2b transmits the current can also be prevented.

As shown in fig. 3-5, the explosion-proof mechanism 2 further comprises a limiting component 2f, and the limiting component 2f comprises a sliding block 2f1 and a sliding groove 2f 2; the sliding groove 2f2 is arranged on the side wall of the protective sleeve 2g1 along the length direction of the shell 1; the slide block 2f1 is fixedly arranged on the trigger piece 2d, and the slide block 2f1 is in sliding fit with the slide groove 2f 2.

When the trigger 2d is connected to the connecting member 2c, the slider 2f1 is located on the side of the slide groove 2f2 close to the contact 2 a. In use, the sound will urge the trigger 2 d. When the trigger 2d is used up, the reset component 2e resets the trigger 2d, and at this time, the trigger 2d slides towards the connecting piece 2c under the action of the reset component 2e, but due to the limitation of the sliding groove 2f2 and the sliding block 2f1, the phenomenon that the trigger 2d is popped up cannot occur, and meanwhile, the trigger 2d and the connecting piece 2c can be prevented from directly colliding.

As shown in fig. 5 and 8, the mount 2h includes a first screw groove 2h1 and a second screw groove 2h 2; the first thread groove 2h1 is formed on the outer wall of the mounting seat 2 h; the second screw groove 2h2 is opened on the inner wall of the housing 1, and the housing 1 is screw-engaged with the first screw groove 2h1 on the mounting seat 2h through the second screw groove 2h 2. When needing the dismouting, only need with mount pad 2h from shell 1 unscrew can. After the audio connector is overhauled, the thread matching is realized through the second thread groove 2h2 arranged on the shell 1 and the first thread groove 2h1 arranged on the mounting seat 2h, and the friction force of the mounting seat 2h is increased by arranging the friction groove 2h3, so that the mounting seat 2h can be easily unscrewed.

Example 2:

compared with embodiment 1, in this embodiment, the housing 1 has an L-shaped bent shell structure, so that the audio connector can be easily inserted into a sound box even when the audio connector is used in a narrow space.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
