In order to make the objectives, technical solutions and beneficial technical effects of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are only for explaining the present invention, not for limiting the present invention.

Referring to FIGS. 1 to 4 , the present invention provides an earphone plug 100 , which mainly expands the functional scope of the earphone, so that the earphone can be used as a disassembly tool. In this embodiment, the earphone plug 100 is a 3.5mm universal earphone, which can be used in electronic devices such as mobile phones and tablet computers with a 3.5mm earphone jack, and the earphone plug 100 also serves as a SIM card holder (not shown in the figure). Use with the removal tool for SD card holder (not shown).

In the embodiment of the present invention, the earphone plug 100 includes a first body 10 and a second body 20 connected to the first body 10; the first body 10 includes a head 101 and a head 101 extending from one end and used for connection The first connecting portion 102 of the second body 20 has a concave receiving groove 103 at one end face of the first connecting portion 102 away from the head 101 ; the second body 20 includes a second connecting portion 201 and one end extending from the second connecting portion 201 The pin 202 is formed and accommodated in the receiving groove 103, and one end of the pin 202 close to the second connecting portion 201 is detachably connected to the first connecting portion 102, that is, the pin 202 and the first connecting portion 102 are detachably connected The detachable connection connects the first body 10 with the second body 20 and accommodates the pins 202 in the accommodating grooves 103 .

In this embodiment, when the earphone plug 100 is used as an earphone, the first main body 10 and the second main body 20 are integrally formed through the detachable connection between the pins 202 and the first connecting portion 102 so as to be inserted into a 3.5mm earphone jack. To receive audio signals, when the earphone plug 100 is used as a disassembly tool, the connection relationship between the pins 202 and the first connecting portion 102 is released, so that the second body 20 is separated from the first body 10, so that the pins 202 on the second body 20 are Can be used to open SIM card holder or SD card holder. It should be noted here that the SIM card holder or the SD card holder is provided with a disassembly hole for opening, and when the pin 202 is inserted into the disassembly hole, the corresponding SIM card holder or SD card holder will be removed from the corresponding electronic device. pop-up for easy installation or replacement of SIM or SD cards.

It can be understood that, the earphone plug 100 not only expands the function of the earphone, but also provides a pin 202 on the second main body 20 that can be separated from the first main body 10 for opening the SIM card holder or the SD card holder. The 202 is also accommodated in the accommodating slot 103 of the first main body 10 when not in use, so that the pin 202 can not only be well protected, but also easy to carry to prevent loss, and can avoid stabbing people or objects during carrying. In addition, the earphone plug 100 can also make the corresponding electronic device not need to be equipped with a special tool for removing the SIM card holder or the SD card holder, so that the production cost of the electronic device can be reduced.

Further, in one embodiment, in order to facilitate the detachable connection between the pin 202 and the first connecting portion 102, one end surface of the pin 202 close to the second connecting portion 201 protrudes to form an external thread 2021, and the inner wall of the receiving groove 103 is concave. There is an inner thread 1031 that can cooperate with the outer thread 2021, and the pin 202 and the first connecting part 102 are detachably connected through the cooperation of the outer thread 2021 and the inner thread 1031. The structure is simple and reliable, which is convenient for production and manufacture, and can reduce the earphones. The production cost of the plug 100, therefore, in order to facilitate the setting of the external thread 2021 and the internal thread 1031, the pins 202 and the receiving grooves 103 are both cylindrical, and the outer diameter of the pins 202 is smaller than the inner diameter of the receiving grooves 103 to facilitate the receiving of the pins 202. In the accommodating groove 103 , the length of the pins 202 is also smaller than the depth of the accommodating groove 103 to prevent the pins 202 from interfering with the bottom of the accommodating groove 103 . In other embodiments, the pin 202 and the first connecting portion 102 may also be detachably connected by snap connection or magnetic attraction.

In the embodiment of the present invention, the first main body 10 is used for receiving the audio signal of the right channel, sending the microphone signal and connecting to the ground. Therefore, two insulating rings (not shown in the figure) are provided on the surface of the first main body 10. ), to divide the first main body 10 into three wiring areas for receiving the right channel audio signal, transmitting the microphone signal and ground connection respectively, the second main body 20 is used for receiving the left channel audio signal, and the third After the two main bodies 20 are connected to the first main body 10 through the detachable connection between the pins 202 and the first connecting part 102, a gap 105 is provided between the second main body 20 and the first main body 10, which can easily isolate the left channel audio signal.

Preferably, the earphone plug 100 further includes an elastic piece 30 embedded in the first main body 10 . Specifically, the elastic piece 30 is embedded in the first connecting portion 102 and is provided in the receiving groove 103 and is used for electrical connection with the pins 202 The conductive portion 301 of the shrapnel 30 is used to facilitate the stereo effect of the headphone plug 100. In addition, it can be understood that the conductive portion 301 and the pin 202 of the elastic sheet 30 are both accommodated in the receiving slot 103, which can not only prevent oxidation, but also help improve The stability of the electrical connection can improve the audio output and input effects of the headset. In this embodiment, the conductive portion 301 is in a “V” shape, which can facilitate the insertion of the pins 202 into and out of the receiving groove 103 . Of course, the conductive portion 301 can also be in an arc shape, which is not specifically limited here.

To sum up, the earphone plug 100 provided by the present invention not only expands the power of the earphone by setting the pin 202 for opening the SIM card holder or the SD card holder on the second main body 20 which can be separated from the first main body 10 . At the same time, the pin 202 is also accommodated in the receiving groove 103 of the first main body 10 when not in use, so that the pin 202 can not only be well protected, but also easy to carry to prevent loss, and can also avoid puncture during the carrying process. injury or object.
