With the continuous development of science and technology, electronic digital products are becoming more and more miniaturized and ultra-thin. The socket needs to undergo multiple plugging and unplugging operations during use, which can easily lead to loosening or changes in the structure of the parts, resulting in unstable contact between the earphone male head and the socket, and affecting the use effect.

Contents of the invention

The purpose of the utility model is to provide a structure-improved earphone socket for the deficiencies of the prior art, which not only has a firm structure, but also has a good use effect and a long service life, and is applicable to ultra-thin series of electronic digital products.

A headphone socket with improved structure, which is assembled on electronic digital products and used to connect with headphone plugs, includes a plastic body provided with an audio jack and several conductive terminals embedded in the plastic body. The entrance end surface of the audio jack is It is an inclined arc surface, and its inclination matches the casing side of the electronic digital product. The conductive terminal is a U-shaped shrapnel, and the electrical contact end of the U-shaped shrapnel faces the inner side of the audio jack.

Wherein, the conductive terminal includes a first elastic piece embedded in one side of the plastic body, a second elastic piece and a third elastic piece embedded in the other side of the plastic body, a fourth elastic piece and a fifth elastic piece embedded in the rear end of the plastic body .

Wherein, the electrical contact end of the conductive terminal is provided with a protrusion.

Wherein, the fourth elastic piece and the fifth elastic piece are both provided with slots for matching with the plastic body.

Wherein, the thickness of the plastic body is 3.6 mm.

Wherein, the side of the plastic body is provided with a locking position for engaging with the circuit board.

Beneficial effects of the utility model: the entrance end face of the audio jack of the headphone socket with the improved structure of the utility model is an inclined arc surface, and its inclination matches the shell side of the electronic digital product, and can be applied to the ultra-thin series For electronic digital products, the conductive terminal is a U-shaped shrapnel, which makes the terminal have better resilience, and the contact with the earphone plug is more stable, and prevents poor contact caused by too many times of plugging and unplugging.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figures 1 to 5, a headphone socket with improved structure is assembled on an electronic digital product for connection with a headphone plug, and includes a plastic body 1 with an audio jack and several sockets embedded in the plastic body 1. The conductive terminal, the entrance end face 11 of the audio jack is an inclined arc surface, and its inclination matches the housing side of the electronic digital product, which can be applied to the ultra-thin series of electronic digital products, and the conductive terminal is U U-shaped shrapnel, the electrical contact end of the U-shaped shrapnel is facing the inner side of the audio jack, so that the resilience of the terminal is better, the contact with the earphone plug is more stable, and the poor contact phenomenon caused by too many times of plugging and unplugging is prevented.

In addition, the entrance end surface 11 of the audio jack is set as an inclined arc surface, which can better guide the insertion of the earphone plug and improve the stability of the contact. A glue point is provided at the end of the inclined entrance for Prevent the deformation of the contact point caused by the insertion of the earphone plug.

Wherein, the conductive terminal includes a first elastic piece 21 embedded on one side of the plastic body 1 , a second elastic piece 22 and a third elastic piece 23 embedded on the other side of the plastic body 1 , and a second elastic piece embedded in the rear end of the plastic body 1 . The four shrapnels 24 and the fifth shrapnel 25 are respectively in contact with different parts of the earphone plug to realize fixation and audio transmission.

Wherein, the electrical contact end of the conductive terminal is provided with a convex shell 3, which can better contact the earphone plug, and at the same time ensure that the earphone plug will not produce abnormal noise due to contact with the plastic body 1.

Wherein, the fourth elastic piece 24 and the fifth elastic piece 25 are provided with a slot 4 for cooperating with the plastic body 1, through which the fourth elastic piece 24 and the fifth elastic piece 25 can be more It is firmly arranged inside the plastic body 1 to prevent loosening of the earphone plug due to multiple insertions.

Wherein, the thickness of the plastic body 1 is 3.6mm, which can be widely used in electronic digital products such as ultra-thin series mobile phones, and meets the current design requirements of ultra-thin mobile phones.

Wherein, the side of the plastic body 1 is provided with a card position 12 for engaging with the circuit board, and the plastic body 1 can be conveniently connected to the circuit board through the card position 12, so that the plastic body 1 can be locked on the circuit board. Better fixation on the top to avoid impact on the solder feet.
