For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0028] See also Figure 1 The figure shows an application scenario of the shrapnel connector in an embodiment of the utility model, wherein the shrapnel connector 100 is arranged in a device housing of the device, wherein the bottom of the shrapnel connector 100 is fixed on the device motherboard 24 of the device, and the shrapnel connector 100 is at least partially exposed from the device housing, so that the corresponding device can be connected to the device motherboard 24 through the shrapnel connector 100.

[0029] See also Figures 2 to 4 As shown, in an embodiment of the utility model, a spring connector 100 is provided, including a connecting portion 10 in a flat plate shape, and the two sides of the connecting portion 10 are respectively bent to form a first protecting portion 11 and a second protecting portion 12, the first protecting portion 11, the second protecting portion 12 and the connecting portion 10 surround an accommodating space 13, one end of the connecting portion 10 is continuously bent into the accommodating space 13 to form an elastic portion 14, and the elastic portion 14 is bent at one end away from the connecting portion 10 to form a contact portion 15 protruding from the accommodating space 13, the first protecting portion 11 at one end away from the contact portion 15 is bent toward the direction close to the second protecting portion 12 to form a first extending portion 20, the first extending portion 20 at one end away from the first protecting portion 11 is bent downward to form a first welding portion 21, the second protecting portion 12 at one end away from the contact portion 15 is bent toward the direction close to the first protecting portion 11 to form a second extending portion 22, and the second extending portion 22 at one end away from the second protecting portion 12 is bent downward to form a second welding portion 23.

[0030] In this embodiment, the flat connecting portion 10 can have a strong supporting function and can effectively support and connect the first protecting portion 11, the second protecting portion 12 and the elastic portion 14. The bottom surfaces of the first protecting portion 11 and the second protecting portion 12 should be arranged in parallel to facilitate the installation of the first protecting portion 11 and the second protecting portion 12 on the main board of the electronic component.

[0031] It is worth noting that the accommodating space 13 is surrounded by the first protection portion 11, the second protection portion 12 and the connecting portion 10. It can be seen that the bottom of the accommodating space 13 is through, so the bottom of the first protection portion 11 and the second protection portion 12 can be cut to adjust the height of the spring connector 100, so that the spring connector 100 can adapt to various types of electronic devices, improving the adaptability of the spring connector 100. In addition, the bottom of the spring connector 100 can be cut, so that a variety of electronic devices can be realized through a stamping die, without the need to replace the die, saving production costs. Because the elastic portion 14 is formed by continuous bending, the spring connector 100 has a certain anti-deformation ability. The first extension portion 20 is formed by bending one end of the first protection portion 11 away from the contact portion 15 toward the direction close to the second protection portion 12, and the second extension portion 22 is formed by bending one end of the second protection portion 12 away from the contact portion 15 toward the direction close to the first protection portion 11, so that the first welding portion 21 and the second welding portion 23 are not directly below the first protection portion 11 and the second protection portion 12 respectively, thereby reducing the distance between the first welding portion 21 and the second welding portion 23, and facilitating the installation of the spring connector 100 on a smaller device motherboard 24 or substrate, thereby achieving the effect that the first welding portion 21 and the second welding portion 23 are accurately positioned and installed in the mounting hole 25 of the device motherboard 24 or the substrate, and facilitating the spring connector 100 to be suitable for a smaller size motherboard, wherein the distance between the first welding portion 21 and the second welding portion 23 is very small. In a specific implementation, the first welding portion 21 and the second welding portion 23 are installed in the same mounting hole 25.

[0032] In this embodiment, the spring connector 100 may be an integrated structure, and the material may be a conductive metal material.

[0033] See also Figure 5 As shown, specifically, the elastic portion 14 includes a first elastic force arm 141 formed by bending upward along a first side edge of the connecting portion 10 , and a second elastic force arm 142 formed by bending the first elastic force arm 141 upward away from the elastic portion 14 .

[0034] Specifically, the elastic portion 14 also includes a third elastic force arm 143, both ends of which are respectively connected to the first elastic force arm 141 and the second elastic force arm 142, and the third elastic force arm 143 is formed by the end of the first elastic force arm 141 extending horizontally toward the connecting portion 10.

[0035] Specifically, the contact portion 15 includes a first extension arm 151 and a second extension arm 152. One end of the elastic portion 14 away from the connecting portion 10 is bent toward the outside of the accommodating space 13 to form the first extension arm 151. One end of the first extension arm 151 away from the elastic portion 14 is bent toward the inside of the accommodating space 13 to form the second extension arm 152.

[0036] Furthermore, in order to allow the contact portion 15 to better contact the charging portion of the electronic device (earphones) that needs to be charged, the contact portion 15 also includes a contact arm 153, the two ends of which are respectively connected to the first extension arm 151 and the second extension arm 152, and the contact arm 153 is formed by bending the end of the first extension arm 151 toward the second extension arm 152. A convex strip 154 ​​extends from one side of the contact arm 153 away from the accommodating space 13, and the size of the convex strip 154 ​​is smaller than the size of the contact arm 153.

[0037] In this embodiment, the end of the first protection portion 11 away from the first welding portion 21 is bent toward the direction close to the second protection portion 12 to form a first buckle portion 111, and the end of the second protection portion 12 away from the second welding portion 23 is bent toward the direction close to the first protection portion 11 to form a second buckle portion 121. The first limiting portion and the second limiting portion are respectively extended from both sides of the end of the contact portion 15 away from the elastic portion 14, and the first limiting portion is used to contact with the first buckle portion 111, and the second limiting portion is used to contact with the second buckle portion 121. It can be understood that, since the elastic portion 14 has an elastic force that causes the contact arm 153 of the elastic portion 14 to extend out of the accommodating space 13 in a natural state, the elastic portion 14 can be limited by the first limiting portion contacting the first buckle portion 111 and the second limiting portion contacting the second buckle portion 121, so that the pre-pressure is maintained within a certain range and the stability of the overall structure is maintained.

[0038] Further, one end of the first protection portion 11 away from the first welding portion 21 is bent toward the direction close to the second protection portion 12 to form the suction portion 112, or one end of the second protection portion 12 away from the second welding portion 23 is bent toward the direction close to the first protection portion 11 to form the suction portion 112. In this embodiment, the suction portion 112 is provided on one end of the first protection portion 11 away from the first welding portion 21, and the suction portion 112 is used to provide suction during patch placement. Preferably, the top surface of the suction portion 112 is parallel to the bottom surfaces of the first protection portion 11 and the second protection portion 12.

[0039] See also Figure 6As shown, one end of the connecting portion 10 away from the contact portion 15 is bent downward to form a third welding portion 17, and the third welding portion 17 has a limiting rib 171 extending toward the direction close to the accommodation; a tin storage groove 172 is provided on one side of the third welding portion 17 away from the limiting rib 171.

[0040] It is worth noting that the setting of the third welding part 17 can effectively improve the installation stability of the spring connector 100. The first welding part 21, the second welding part 23 and the third welding part 17 are all inserted into the mounting hole 25 of the device mainboard 24 or the substrate in a synchronous plug-in manner, so that the welding between the protection part and the device mainboard 24 or the substrate is more stable, avoiding the phenomenon of poor contact due to welding leakage, and the plugging of the first welding part 21, the second welding part 23 and the third welding part 17 with the device mainboard 24 or the substrate can further provide a stable fixing point and drive the positioning purpose; through the setting of the limiting rib 171, the thickness of the third welding part 17 is increased, so that the strength of the welding part can be strengthened and not easily deformed, the positioning accuracy of the patch is improved, and at the same time, the manufacturing difficulty of the pin hole of the corresponding device mainboard 24 is reduced to reduce the cost. Through the setting of the tin storage groove 172, during welding, the tin paste can be stored in the tin storage groove 172, thereby improving the welding strength of the third welding part 17.

[0041] In this embodiment, a through hole 113 is formed on the first protection portion 11 and the second protection portion 12, and the through hole 113 is used to reduce the size of the first protection portion 11 and the second protection portion 12, thereby reducing the electroplating area of ​​the spring connector 100 and reducing costs during the electroplating process.

[0042] The utility model also provides an electronic device, comprising the above-mentioned spring connector 100 .

[0043] In summary, the first extension portion 20 is formed by bending one end of the first protection portion 11 away from the contact portion 15 toward the direction close to the second protection portion 12, and the second extension portion 22 is formed by bending one end of the second protection portion 12 away from the contact portion 15 toward the direction close to the first protection portion 11, so that the first welding portion 21 and the second welding portion 23 are not directly below the first protection portion 11 and the second protection portion 12 respectively, thereby reducing the distance between the first welding portion 21 and the second welding portion 23, making it easier for the spring connector 100 to be installed on a smaller device motherboard 24 or substrate, thereby achieving the effect of accurately positioning the spring connector 100 and installing it in the mounting hole 25 of the device motherboard 24 or substrate, so that the spring connector 100 is suitable for smaller-sized motherboards.
