Description

Technical Field

[0001] The present invention relates to the field of electronic equipment accessories, in particular to an earphone jack anti-dropping device. Background Art

[0002] The wired headphone interface integrates multiple electrical signal transmission functions, which can transmit left channel, right channel, ground and audio signals. By plugging the interface of the wired headphone into an electronic device, the user can listen to different audio sources played by the electronic device according to the user's selection. It is convenient and simple to use. However, when wearing wired headphones to listen to the audio source played by a mobile electronic device, if the mobile electronic device suddenly falls to the ground, it will cause damage to the electronic device. In the existing technology, the wired headphone is tied to the mobile electronic device. When the mobile electronic device falls, the fallen mobile electronic device is pulled by the wired headphone, preventing the mobile electronic device from continuing to fall, so that the mobile electronic device is protected in time.

[0003] Although this method can effectively protect the mobile electronic device, when the mobile electronic device is heavy, the wired earphones will be pulled downward when the mobile electronic device falls, causing great damage to the ears of the person wearing the wired earphones, seriously affecting the safety of the user. In addition, since the wired earphones need to be bound to the mobile electronic device each time they are used, if the user believes that the mobile electronic device is light or more drop-resistant and does not need to be bound, the redundant binding steps in the process of connecting the wired earphones to the mobile electronic device will cause unnecessary trouble to the user, affecting the user experience. Summary of the Invention

[0004] In order to overcome the disadvantages that after binding wired headphones to a mobile electronic device, the lateral pulling force generated when the heavy mobile electronic device falls may cause great damage to the human ear, and if the user does not need to use the binding function, the redundant binding step in the process of connecting the wired headphones to the mobile electronic device will cause unnecessary trouble to the user, the present invention provides a headphone jack anti-drop device.

When the wired headphones are inserted, the user turns the knob, and the knob synchronously pushes all the clamping rods through the wedge blocks, and each clamping rod pushes each rubber pad outward to fit tightly against the inner wall of the socket of the mobile electronic device, thereby opening the first-level clamping protection. If it is necessary to improve the protection effect of the mobile electronic device, the user continues to turn the knob, and the moving clamping rod bends the arc-shaped steel sheet between the clamping rod and the upper end of the fixing rod upward by cooperating with the fixing rod provided on the rubber pad, so that the bent middle part of each arc-shaped steel sheet is respectively pressed against the locking ball at the upper end of the adjacent rubber pad, so that the locking ball is uniformly stuck on the inner wall of the socket under the thrust of the arc-shaped steel sheet, thereby opening the second-level clamping protection;

[0031] like Figure 5 As shown, all elastic members 36 are spring sheets.

[0032] like Figure 3 、 Figure 5 and Figure 10 As shown, a slot 321 structure is provided on the inner side of the lower end of each clamping rod 32; a locking block 322 structure is provided in the slot 321 structure at the lower end of each clamping rod 32; a locking slot 411 structure adapted to the locking block 322 structure is provided on the middle part of the outer side of each wedge block 41; and a clamping block 412 structure is provided on the inner side of each wedge block 41.

[0033] like Figure 2 and Figure 3 As shown, a light source 5 is installed around the lower side of the insulating sleeve 1; a plurality of empty slots 401 structures corresponding to the light sources 5 are opened on the lower side of the knob 4; a colorless transparent sheet 6 is fixed in each empty slot 401; and a layer of colored transparent sheet 61 is attached to the position of each colorless transparent sheet 6 corresponding to the adjacent lock slot 411.

[0034] General usage of this headphone jack anti-drop device:

[0035] An adapter consisting of a connector 21 and a socket 22 is provided in the insulating sleeve 1 of the headphone jack anti-falling device. Before connecting the wired headset and the mobile electronic device, first insert the plug of the wired headset into the socket 22 of the adapter, and then insert the connector 21 of the adapter into the socket of the mobile electronic device. At this time, all the clamping blocks 412 are in contact with the plug of the wired headset, and all the rubber pads 31 are in contact with the inner wall of the socket of the mobile electronic device. When the wired headset and the mobile electronic device are pulled in opposite directions, there is friction resistance between the clamping blocks 412 and the plug of the wired headset, and there is also friction resistance between the rubber pads 31 and the inner wall of the socket of the mobile electronic device, so that the plug of the wired headset is not easy to fall off from the socket 22, and the connector 21 is not easy to fall off from the socket of the mobile electronic device, so that the connection between the wired headset and the mobile electronic device is provided with basic anti-falling protection.

[0036] After the user wears the wired headphones and turns on the audio source of the mobile electronic device, the mobile electronic device transmits audio information to the wired headphones through the socket, adapter and plug in sequence, and the user listens to the audio source played by the mobile electronic device normally through the wired headphones.

[0037] How to activate the first-level clamping protection of the headphone jack anti-drop device:

[0038] After the wired earphones and the mobile electronic device are connected through the earphone jack anti-dropping device according to the above steps, the connection between the wired earphones and the mobile electronic device is basically protected from falling off.

[0039] Then the user rotates the knob 4, which drives all the wedge blocks 41 to rotate synchronously, allowing the rotating wedge blocks 41 to push the clamping rod 32 through the card slot 321, squeezing the rubber pad 31 outward, and the clamping rod 32 drives the elastic part 36 to compress, turning on the first-level clamping protection of the headphone jack anti-falling device, thereby increasing the clamping force of the upper end of the rubber pad 31 on the inner wall of the mobile electronic device socket. When the mobile electronic device is light in weight, when the fallen mobile electronic device pulls the side wired earphones, the friction between the rubber pad 31 and the inner wall of the mobile electronic device socket is sufficient to ensure that the connector 21 of the headphone jack anti-falling device will not fall off from the socket of the mobile electronic device, thereby protecting the mobile electronic device.

[0040] How to activate the secondary clamping protection of the headphone jack anti-drop device:

[0041] After the connector 21 of the headphone jack anti-dropping device is inserted into the socket of the mobile electronic device, the light source 5 emits light outward through the colorless transparent sheet 6. After the user connects the wired headphones and the mobile electronic device through the headphone jack anti-dropping device according to the above steps and rotates the knob 4 to turn on the first-level clamping protection, if the mobile electronic device is heavy, it is necessary to turn on the second-level clamping protection of the headphone jack anti-dropping device.

[0042] The user continues to rotate the knob 4 on the basis of opening the first-level clamping protection. The knob 4 continues to push the clamping rod 32 through the wedge block 41, further increasing the clamping force of the upper end of the rubber pad 31 on the inner wall of the mobile electronic device socket. At the same time, the clamping rod 32 moving outward passes through the outer inclined surface 323 and cooperates with the inner inclined surface 331 of the stationary fixing rod 33 to press the push rod 341 upward to drive the arc-shaped steel sheet 34 to bend outward. The curved portion of the arc-shaped steel sheet 34 presses the lock ball 35 tightly against the inner wall of the mobile electronic device socket. The locking ball 35 is stuck on the inner wall of the mobile electronic device socket under the thrust of the arc-shaped steel sheet 34. During this process, the locking groove 411 of the rotating wedge block 41 is locked into the locking block 322 of the clamping rod 32, so that the clamping rod 32 and the wedge block 41 are locked together. When the wedge block 41 squeezes the clamping rod 32 to drive the elastic part 36 to be compressed, the compressed elastic part 36 applies a reverse thrust to the wedge block 41 through the clamping rod 32, so that the clamping block 412 of the wedge block 41 is close to the plug of the wired headset, and the secondary clamping protection is activated.

[0043] When the mobile electronic device is heavy, when the dropped mobile electronic device pulls the wired earphones on the side, the friction between the rubber pad 31 and the inner wall of the mobile electronic device socket, and the lock ball 35 stuck on the inner wall of the mobile electronic device socket, are sufficient to ensure that the connector 21 of the earphone socket anti-falling device will not fall off from the socket of the mobile electronic device, and the friction between the clamping block 412 and the plug of the wired earphones is sufficient to ensure that the plug of the wired earphones will not loosen from the socket 22 of the earphone socket anti-falling device, thereby protecting the mobile electronic device.

[0044] After the secondary clamping protection is activated, the rotating wedge block 41 drives the colored transparent sheet 61 to align with the light source 5, causing the light emitted outward from the light source 5 to change color, reminding the user that the secondary clamping protection has been activated.

[0045] When the mobile electronic device is too heavy, when the dropped mobile electronic device pulls the wired earphones on the side, the locking ball 35 fixed on the inner wall of the mobile electronic device socket is pushed inward by the socket of the mobile electronic device, and the locking ball 35 pushes the arc-shaped steel sheet 34 in the opposite direction, so that the locking ball 35 is pressed into the inside of the rubber pad 31. At this time, the connector 21 of the earphone jack anti-drop device directly falls off from the socket of the mobile electronic device, preventing the impact force generated by the heavy mobile electronic device at the moment of falling from injuring the user, thereby providing self-protection for the user.

[0046] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
