[0002] like Figure 1 and Figure 2 As shown, during the stamping and bending process of existing audio connector metal shells, if the bending angle is unstable, the bending feet will tilt upwards or downwards, and adjacent bending feet will not be on the same plane, resulting in unevenness. In severe cases, this can lead to the bending foot solder pins failing to match the PCB board holes for insertion. Additionally, existing audio connector metal shells have the problem of unstable attachment to the plastic mounting platform, making them prone to detachment, which seriously affects the product's functionality. At the same time, the unstable stamping and bending angle requires frequent adjustments to the stamping machine, affecting production efficiency and significantly increasing production costs.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1:

[0022] This embodiment discloses a metal housing for an audio connector with a bent stabilizing groove structure, such as Figure 3 and Figure 4As shown, it mainly includes a symmetrical metal housing body 207; both ends of the metal housing body 207 are bent downwards to form solder pins 103 and bent feet 102. The opening of the metal housing body 207 faces downwards and covers the plastic body 208 of the audio connector. The solder pins 103 extend downwards to match the PCB board holes 210, and the bent feet 102 extend downwards to contact the mounting platform 209 of the plastic body 208 of the audio connector, achieving stable mounting. A groove is provided inside the bend, called the bend stabilizing groove 101. In this embodiment, the bend refers to the transition connection between the metal housing body 207 and the solder pins 103, and the transition connection between the metal housing body 207 and the bent feet 102.

[0023] The principle of this embodiment is as follows: The metal outer shell 207 is generally made of stainless steel. Stainless steel has a high resilience, so when designing the mold, for example, a stamping mold that requires a 90° bend, compensation needs to be made on the mold to ensure the angle is greater than 90° to compensate for the springback. Furthermore, the stainless steel outer shell 207 is relatively thick, making bending difficult. Therefore, this embodiment addresses this by creating a bending stabilizing groove 101. This reduces the thickness at the bending point, making it easier to bend. It also facilitates deformation and allows for more precise control of the bending position and angle.

[0024] In summary, this embodiment, by providing a bending stabilizing groove 101 structure at the root of the bend, can ensure a stable bending angle, avoid differences in bending angles between adjacent bends, and prevent the bends from tilting upwards or downwards. At the same time, it ensures stable attachment of the product's metal shell and plastic parts to the mounting platform, and ensures that the bend solder pins match the PCB board holes to insert into the board, thus guaranteeing stable signal transmission of the product.

[0025] Example 2:

[0026] Based on Embodiment 1, this embodiment discloses an audio connector, such as... Figure 5 and Figure 6 As shown, it mainly includes: a bending stabilizing groove 101, a bending foot 102, a welding pin 103, a first terminal 201, a second terminal 202, a third terminal 203, a fourth terminal 204, a fifth terminal 205, a sixth terminal 206, a metal housing body 207, a plastic body 208, a mounting platform 209, and a PCB board hole 210. The bending stabilizing groove 101 is located inside the bending point. In this embodiment, the bending point refers to the transition connection between the metal housing body 207 and the welding pin 103, and the transition connection between the metal housing body 207 and the bending foot 102.

[0027] The first terminal 201, the second terminal 202, the third terminal 203, the fourth terminal 204, the fifth terminal 205, and the sixth terminal 206 are all installed inside the plastic body 208. The metal outer shell body 207 is fastened to the plastic body 208, and the bent foot 102 is attached to the hanging platform 209. The first terminal 201, the second terminal 202, the third terminal 203, the fourth terminal 204, the fifth terminal 205, and the sixth terminal 206 all extend downward to match the PCB board hole 210; at the same time, the solder pin 103 also matches the PCB board hole 210.
