Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0026] like Figures 1 to 6 As shown in the figure, a vertical headphone jack with shielding function includes a base 1, a left channel terminal 2, a right channel terminal 3, and a grounding terminal 4. The base 1 is provided with a socket 5. The left channel terminal 2, the right channel terminal 3, and the grounding terminal 4 are all located inside the base 1 at positions corresponding to the socket 5. The base 1 is also provided with a spring piece 6 connected to the grounding terminal 4. The surface of the base 1 corresponding to the socket 5 is a shielding surface 7. The spring piece 6 extends outward toward the shielding surface 7 with at least one elastic bend 8, which is used to contact the metal parts on the surface of the mechanism.

[0027] The beneficial effects of this design are as follows: the vertical headphone jack of this utility model has a shielding function. When the headphone plug is inserted into the socket of the base, the headphone plug is electrically connected to the grounding terminal. At the same time, the metal parts on the surface of the mechanism are in contact with the elastic bending of the spring, and the spring is connected to the grounding terminal. This forms a shielding circuit, which plays a better grounding role and effectively suppresses high-frequency interference.

[0028] Furthermore, the elastic bend 8 and the shielding surface 7 form an acute angle between them.

[0029] The beneficial effects of such an arrangement are as follows: the elastic bending has elasticity, the acute angle provides a certain activity space for the elastic bending, has a compensation effect, helps the elastic bending to better contact the mechanism surface metal piece, and when the mechanism surface metal piece has a certain gap with the shielding surface, the elastic bending can also contact the mechanism surface metal piece.

[0030] Further arrangement, the elastic sheet 6 extends towards the outside of the shielding surface 7 two elastic bendings 8 for contacting the mechanism surface metal piece, the two elastic bendings 8 are symmetrically arranged along the center line of the elastic sheet 6, and the included angle of the two elastic bendings 8 is located on the side away from each other.

[0031] The beneficial effects of such an arrangement are as follows: the two symmetric elastic bendings increase the contact area with the mechanism surface metal piece, ensuring that the shielding circuit can be stably formed, and the structure of the two elastic bendings expanding outward has a more stable structure and is more stable when contacting the mechanism surface metal piece.

[0032] Further arrangement, the elastic sheet 6 is electrically connected to the grounding terminal 4 through an elastic bending piece 9, and the elastic bending piece 9 abuts against the side surface of the grounding terminal 4 away from the jack 5.

[0033] The beneficial effects of such an arrangement are as follows: the elastic bending piece helps the elastic sheet to stably electrically connect with the grounding terminal, and when the earphone plug is inserted into the jack and electrically connected with the grounding terminal, the grounding terminal will elastically deform, and the elastic bending piece on the other side of the grounding terminal still maintains electrical connection with the grounding terminal.

[0034] Further arrangement, the base 1 further comprises a left channel static needle 10 for abutting and cooperating with the left channel terminal 2 and a right channel static needle 11 for abutting and cooperating with the right channel terminal 3, when the earphone plug is inserted into the jack 5, the left channel terminal 2 is separated from the left channel static needle 10, and the right channel terminal 3 is separated from the right channel static needle 11.

[0035] The beneficial effects of such an arrangement are as follows: when the earphone plug is pulled out of the jack, the left channel terminal and the right channel terminal will be reset to the position of abutting the left channel static needle and the right channel static needle, respectively, and the left channel static needle and the right channel static needle also have pin feet connected to the circuit, so that when they abut, a short circuit is formed, and the circuit is quickly disconnected; on the contrary, when the earphone plug is inserted into the jack, they are separated, and the circuit is quickly connected.

[0036] Further arrangement, the left channel terminal 2, the right channel terminal 3, the left channel static needle 10, and the right channel static needle 11 are all in plug-in cooperation with the base 1, and the side edges of the left channel terminal 2, the right channel terminal 3, the left channel static needle 10, and the right channel static needle 11 are all provided with an angle 12 for plug-in cooperation with the base 1.

[0037] The beneficial effects of such arrangement are as follows: the left channel terminal, the right channel terminal and the two static needles are all provided with a corner, which can prevent the wrong position from being assembled.

[0038] Further arrangement, the left channel terminal 2, the right channel terminal 3 and the ground terminal 4 are all matched with the base 1 through the elastic sheet type buckle 13.

[0039] The beneficial effects of such arrangement are as follows: the three terminals are all matched with the base through the elastic sheet type buckle which is integrally formed with the terminal, so that the product is more stable after being assembled, and the terminal is prevented from falling off.

[0040] Further arrangement, the elastic sheet 6 is made of stainless steel.

[0041] The beneficial effects of such arrangement are as follows: the elastic sheet made of stainless steel has better electromagnetic shielding effect, reduces the interference of electromagnetic wave, and the stainless steel material has conductivity but weak conductivity, so it is widely used in the occasion where conductivity is needed but high conductivity is not needed, because it has good mechanical properties and corrosion resistance.

[0042] The above only discloses the preferred embodiment of the utility model, of course, cannot limit the right scope of the utility model, therefore, the equivalent changes made according to the utility model claim still belong to the range covered by the utility model.
