For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in the present invention will not be described separately.

[0029] The present invention provides a spring pin connector. Figures 1 to 9The spring pin connector 10 includes an insulating body 1 and a plurality of terminals 2. The insulating body 1 is used to fix all the terminals 2 and plays a role in supporting and limiting the main body. The terminals 2 are used to connect the electronic device with an external device to realize data or signal transmission between the electronic device and the external device. The plurality of terminals 2 are arranged at intervals and embedded in the insulating body 1. The terminal 2 includes a connecting arm 21 and a contact head 22. The connecting arm 21 has a welding end and a connecting end relative to each other. The welding end is exposed to the insulating body 1. The welding end is used to be fixedly connected to the electronic device by welding or other means. The portion of the terminal 2 close to the connecting end is provided in the insulating body 1 to realize the fixation of the terminal 2. The connecting end is integrally formed and connected to the edge of the contact head 22. The middle part of the contact head 22 is stretched upward to form a convex portion 221 of the contact head 22. The front of the insulating body 1 is provided with an opening. The convex portion 221 passes through the opening and protrudes from the front of the insulating body 1. The convex portion 221 is used to elastically abut against the external device to realize signal or data transmission. Thus, when the protrusion 221 is pressed, the contact head 22 can move toward the back side of the insulating body 1 (the surface opposite to the front side of the insulating body 1), and the connecting arm 21 provides elastic force for the contact head 22, thereby facilitating stable contact between the contact head 22 and the external device, thereby enabling stable and reliable data transmission and the transmission of large current signals. The spring pin connector 10 of the present invention embodiment is thin and only requires a small height space to accommodate the spring pin connector 10, which is conducive to the lightweight design of electronic devices. Moreover, since the height of the contact head 22 is reduced, when the external device abuts against the contact head 22, the force arm of the contact head 22 changes, which reduces the stress, thereby greatly reducing the risk of vibration and transient disconnection when the contact head 22 elastically abuts. Moreover, the terminal 2 in the spring pin connector 10 is an integrally formed structure (i.e., formed by an integral forming technology), and the protrusion 221 is a sheet metal stretching formed structure (i.e., formed by a sheet metal stretching technology). This makes processing and manufacturing simple, the terminal 2 itself is reliably connected, and when the terminal 2 is integrally formed, an arc structure 23 is provided at the bending part of the terminal to make the overall outer surface of the terminal 2 transition smoothly, effectively avoiding the problem of damage to the terminal 2 caused by scratching the insulating body 1 during elastic movement, and avoiding affecting the stability and reliability of the terminal 2 transmission.

[0030] It is understandable that the current spring pin connectors cannot meet the demand for reducing the risk of instantaneous disconnection due to vibration. The spring pin connector 10 of the embodiment of the utility model is not only taller than the existing spring pin connector 10, but also can meet the functional requirement of effectively reducing the risk of instantaneous disconnection due to vibration.

[0031] For insulating body 1, see Figures 1 to 6 In some embodiments, the insulating body 1 may be provided with a limiting structure 11 facing the contact head 22. The limiting structure 11 is used to limit the contact head 22 to prevent the height of the contact head 22 from being too high, thereby effectively ensuring the spring height consistency of the spring pin connector 10.

[0032] Optionally, the limiting structure 11 may include a limiting ring 111, which may be provided on the front surface of the insulating body 1 and surround the outer periphery of the opening of the opening. The limiting ring 111 is provided with an abutting structure 1111 at one end near the opening. The protrusion 221 passes through the opening of the limiting ring 111 and at least partially protrudes from the front surface of the insulating body 1. The abutting structure 1111 is used to abut the edge of the contact head 22, thereby limiting the contact head 22 and preventing the height of the contact head 22 from being too high, which can effectively ensure the spring height consistency of the spring pin connector 10. Of course, in actual application, when the contact head 22 is not abutting against an external device, the edge of the contact head 22 may also be slightly lower than the wall surface of the limiting ring 111 near the end of the opening, as long as it can play a limiting role.

[0033] Optionally, a protective structure 112 can be provided on the wall surface of the limiting ring 111 facing the contact head 22. The cross-sectional area of ​​the protective structure 112 gradually increases along the direction from the opening to the limiting ring 111. That is, the opening of the limiting ring 111 can gradually decrease in the direction away from the contact head 22. Therefore, when the contact head 22 elastically moves up and down within the limiting ring 111, the protective structure 112 plays a good transition role for the contact head 22, which can reduce the contact head 22 from being scratched by the limiting ring 111, thereby protecting the contact head 22, reducing wear, and increasing the service life. Specifically, the protective structure 112 can be in the shape of an arc surface to prevent sharp protrusions from scratching the contact head 22.

[0034] For terminal 2, see Figure 7 and Figure 8 In some embodiments, the thickness W of the edge of the contact head 22 and the thickness W of the connecting arm 21 (along the direction from the front to the back of the insulating body 1) can be 0.1 to 0.2 mm, and the height H1 of the protrusion 221 (along the direction from the front to the back of the insulating body 1) can be 1 to 1.5 mm. In practical applications, the thickness W of the edge of the contact head 22 and the connecting arm 21 can be 0.12 mm, and the height H1 of the protrusion 221 can be 1.3 mm. The terminal 2 of the embodiment of the present invention has a very small thickness and height, and only a very small height space is required to accommodate the spring pin connector 10, which is conducive to the lightweight design of electronic devices. In addition, since the height of the contact head 22 is reduced, when an external device abuts against the contact head 22, the force arm of the contact head 22 changes, so that the stress is reduced, thereby greatly reducing the risk of vibration and instantaneous disconnection when the contact head 22 elastically abuts.

[0035] Optionally, the connecting arm 21 can have a first parallel portion 211, an oblique portion 212 and a second parallel portion 213, the two ends of the oblique portion 212 are integrally connected to the first parallel portion 211 and the second parallel portion 213 respectively, the first parallel portion 211 is located at the welding end and is partially embedded in the insulating body 1, the second parallel portion 213 is located at the connecting end, the second parallel portion 213 is closer to the front of the insulating body 1 than the first parallel portion 211, and the second parallel portion 213 is integrally formed with a contact head 22 in the direction protruding from the front of the insulating body 1. Its structure is reliable, which is conducive to ensuring the stability of data and signal transmission.

[0036] Specifically, the first parallel portion 211 may be provided with a through hole 2111 to facilitate positioning of the terminal 2 .

[0037] Specifically, protrusions 2112 are provided on both side surfaces of the first parallel portion 211 to prevent the terminal 2 from being loosened.

[0038] Specifically, combined Figures 3 to 8 The front side of the insulating body 1 may be provided with a hollow hole 12 corresponding to the oblique portion 212 and part of the first parallel portion 211. This not only makes it more convenient to install the terminal 2, but also reserves movement space for the oblique portion 212 and part of the first parallel portion 211 when the terminal 2 moves elastically.

[0039] Furthermore, the abutment structure 1111 can be a groove, which passes through the bottom surface of the limiting ring 111 (the surface closer to one end of the edge of the contact head 22) and the wall surface of the limiting ring 111 close to the hollow hole 12. This not only makes it more convenient to process the abutment structure 1111, but also when the edge of the contact head 22 abuts against the abutment structure 1111, the second parallel portion 213 can also abut against the abutment structure 1111, so that the force area of ​​the terminal 2 is larger and the force is more balanced, further reducing the risk of instantaneous disconnection of the terminal 2.

[0040] Furthermore, the bottom surface of the groove is parallel to the edge of the second parallel portion 213 and the contact head 22, which facilitates the abutment of the edge of the second parallel portion 213 and the contact head 22, not only increasing the force area when the terminal 2 abuts against the external device, but also avoiding scratching the edge of the second parallel portion 213 and the contact head 22.

[0041] In practical applications, the height H2 of the oblique portion 212 may be 0.4 to 0.7 mm, thereby further limiting the height space required to lower the terminal 2. Furthermore, the angle between the oblique portion 212 and the first parallel portion may be between 135 and 150 degrees.

[0042] Optionally, the protrusion 221 may include a peripheral structure and a contact structure, the edge of the contact head 22 is annular, one end of the peripheral structure is connected to the edge of the contact head 22, and the other end extends upward and is annularly surrounded by the periphery of the contact structure, and the contact structure is planar, which can ensure that the abutment structure can fully abut against the external device, thereby ensuring signal transmission between the two.

[0043] Specifically, the protrusion 221 can be roughly truncated cone-shaped, and the vertical cross-section of the peripheral structure can be roughly trumpet-shaped. Along the direction from the protrusion 221 to the edge of the contact head 22, the peripheral structure (such as the outer diameter, etc.) gradually shrinks, and the distance between the peripheral structure and the wall surface of the limiting ring 111 gradually increases. This not only facilitates processing and facilitates the stretching and forming of the protrusion 221, but also enables the transition of the protrusion 221 to be smooth. When the protrusion 221 elastically moves up and down in the limiting ring 111, the scratches of the limiting ring 111 on the protrusion 221 can be reduced, thereby protecting the protrusion 221, reducing wear and increasing service life.

[0044] In some embodiments, the spring pin connector 10 may further include a packaging member 3, see Figures 1 to 8 The encapsulation member 3 is integrally formed with the insulating body 1 and the plurality of terminals 2, with the portion of the terminal 2 near the connection end being sandwiched between the insulating body 1 and the encapsulation member 3. During encapsulation, the insulating body 1 and terminal 2 assembly can be placed in an injection mold, and the encapsulation member 3 can be formed using injection molding technology, thereby effectively securing the terminals 2 and improving the firmness and reliability of the terminal 2 fixation.

[0045] In some embodiments, a plurality of mounting grooves 13 may be provided on the back of the insulating body 1 , the opening being connected to one end of the mounting groove 13 , and a terminal 2 being installed in a mounting groove 13 , thereby facilitating the installation of the terminal 2 .

[0046] Furthermore, the opening of the mounting groove 13 can pass through the back side (the surface opposite to the front side of the insulating body 1) and the side surface (the surface connecting the front and back sides of the insulating body 1), so that it is very convenient to install the terminal 2 and to form the package 3 by injection molding technology.

[0047] Furthermore, when molding the package 3 , the package 3 can cover all openings of the mounting groove 13 on the side of the insulating body 1 (i.e., all gaps between the side of the insulating body 1 and the terminal 2 ), thereby ensuring the firmness and reliability of the installation of the terminal 2 .

[0048] In specific applications, the bottom of the contact head 22 can be optionally provided with an elastic component or an integrally formed elastic arm to further enhance the contact elastic force of the contact head 22. The elastic component can be a spring, etc. Of course, the elastic component and the elastic arm can also be omitted.

[0049] The present invention also provides an electronic device, which includes a device body, and the device body has a spring pin connector 10. The spring pin connector 10 includes an insulating body 1 and a plurality of terminals 2, which are arranged at intervals and embedded in the insulating body 1. The terminals 2 include a connecting arm 21 and a contact head 22. The connecting arm 21 has a welding end and a connecting end opposite to each other, and the welding end is exposed to the insulating body 1. The portion of the terminal 2 close to the connecting end is provided in the insulating body 1. The connecting end is integrally formed and connected to the edge of the contact head 22. The middle portion of the contact head 22 is stretched upward to form a convex portion 221 of the contact head 22. The front surface of the insulating body 1 is provided with an opening. The convex portion 221 passes through the opening and protrudes from the front surface of the insulating body 1, and is used to elastically abut with an external device to achieve signal or data transmission. The spring pin connector 10 of the embodiment of the present invention has a small thickness and only requires a very small height space to accommodate the spring pin connector 10, which is conducive to the lightweight design of electronic equipment. In addition, since the height of the contact head 22 is reduced, when the external device abuts against the contact head 22, the force arm of the contact head 22 changes, so that the stress is reduced, thereby greatly reducing the risk of instantaneous vibration disconnection when the contact head 22 elastically abuts.

[0050] Specifically, the electronic equipment may be various household appliances and large equipment in the fields of science and technology, energy manufacturing, etc., such as mobile phones, various electrical appliances, etc.

[0051] The method for manufacturing the pogo pin connector 10 may include the following steps:

[0052] S1 (see Figures 7 to 9 ): The terminal 2 is formed by an integrated molding technology, wherein the middle portion of the contact head 22 of the terminal 2 is stretched upward to form a convex portion 221 of the contact head 22, and the welding ends of multiple terminals 2 are integrally connected to the same material strip 4 to form a terminal 2 assembly;

[0054] S3 (see Figure 9 ): Place the terminal 2 on the insulating body 1 so that the protrusion 221 passes through the opening and protrudes from the front of the insulating body 1;

[0055] S4 (see Figure 9 ): Place the insulating body 1 and terminal 2 components in an injection mold, and form a package 3 by injection molding technology. The portion of each terminal 2 close to the connection end is sandwiched between the insulating body 1 and the package 3. The insulating body 1 and the package 3 fix the terminal 2;

[0056] S5 (see Figure 1 ):Remove excess material strip 4.

[0057] Step S1 may specifically include: stretching the metal sheet into a terminal 2 through sheet metal, wherein the metal sheet is integrally stretched into a connecting arm 21, and the middle portion of the contact head 22 of the metal sheet is stretched into a columnar contact head 22; the welding end of each terminal 2 may be integrally connected to the same material strip 4, thereby forming a terminal 2 assembly.

[0058] In step S2 , the insulating body 1 may be injection-molded with a plastic material.

[0059] In step S4, the terminals 2 can be connected to the insulating body 1 by insert injection molding. Step S3 can specifically include placing the insulating body 1 and terminal 2 assembly in an injection mold. The package 3 can be formed using automatic pull injection molding technology. The package 3 can be plate-shaped. The insulating body 1 can be provided with a pre-set hole. When the package 3 is formed, the portion of each terminal 2 near the connection end is sandwiched between the insulating body 1 and the package 3. Plastic can flow into the pre-set hole, making the package 3 more securely connected to the main body of the insulating body 1.

[0060] In step S5 , the excess material strip 4 can be removed by cutting it off in various ways such as punching, thereby obtaining the spring pin connector 10 .

[0061] The manufacturing method of the spring pin connector 10 provided in the embodiment of the present invention manufactures the spring pin connector 10 through secondary IM (injection molding), which not only can effectively fix the terminal 2 to prevent the terminal 2 from falling out, but also avoids affecting the movement of the contact head 22. The contact head 22 can not only move up and down relative to the connecting arm 21, but also can make use of the elasticity of the connecting arm 21 so that the contact head 22 can well abut against the external device to ensure the reliability of signal or data transmission.

The spring pin connector 10 of the embodiment of the present invention has a small thickness and only requires a very small height space to accommodate the spring pin connector 10, which is conducive to the lightweight design of electronic devices. In addition, since the height of the contact head 22 is reduced, when the external device abuts against the contact head 22, the force arm of the contact head 22 changes, so that the stress is reduced, thereby greatly reducing the risk of vibration and instantaneous disconnection when the contact head 22 elastically abuts. In addition, the terminal 2 in the spring pin connector 10 is an integrally formed structure (that is, formed by an integral forming technology), and the protrusion 221 is a sheet metal stretching forming structure (that is, formed by a sheet metal stretching technology).
