Technical Field
[0001] This utility model belongs to the technical field of Pogo Pin components, and particularly relates to a shielded waterproof Pogo Pin component. Background Technology
[0002] A pogo pin is a spring-loaded probe connector composed of a pin shaft, a spring, and a tube, all precisely riveted together. The surface is typically gold-plated to enhance conductivity and corrosion resistance. Its core function is to provide stable contact force through spring compression, enabling efficient transmission of current or signals. Widely used in mobile phones, wearable devices, automotive electronics, and other fields, it boasts advantages such as small size, long lifespan (up to 500,000 mating cycles), and adaptability to high frequencies and high currents.
[0003] Existing Pogo Pin assemblies often lack an automatic shielding structure, leaving the pin shaft directly exposed when not in use. This makes them susceptible to water vapor and dust erosion, leading to waterproofing failure, which in turn affects the stability of electrical connections and shortens the lifespan of the assembly. Therefore, an improved shielded waterproof Pogo Pin assembly is proposed. Utility Model Content

The output shaft end of the electric push rod is fixedly installed to the ring. A support rod is fixedly installed on the ring. Symmetrical protective frames are provided on both sides of the needle tube. A rubber frame is provided on the inner wall of the protective frame. An electric push rod is fixedly installed on the support rod. A connecting strip is fixedly installed at the output shaft end of the electric push rod, and the ends of the connecting strip are respectively fixedly installed to the protective frames.
[0006] As a further description of the above solution: by setting up the needle shaft, spring, needle tube, tail needle, electric push rod one, ring, support rod, protective frame, rubber frame, electric push rod two, and connecting strip to work together, the needle shaft can be automatically shielded and protected when not in operation, improving the waterproof effect, extending the service life, and making it highly practical.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution:
[0024] A shielded waterproof Pogo Pin assembly includes a needle shaft 1, a spring disposed within the needle shaft 1, a needle tube 2 slidably disposed on the needle shaft 1, and a tail needle 3 fixedly mounted at the end of the needle shaft 1. A disc 4 is fixedly mounted at the end of the needle shaft 1, and an electric push rod 5 is fixedly mounted on the disc 4. A ring 6 is slidably disposed on the needle shaft 1. The output shaft end of the electric push rod 5 is fixedly mounted to the ring 6. A support rod 7 is fixedly mounted on the ring 6. Symmetrical protective frames 8 are provided on both sides of the needle tube 2. A rubber frame is provided on the inner wall of the protective frame 8. An electric push rod 9 is fixedly mounted on the support rod 7. A connecting strip 10 is fixedly mounted at the output shaft end of the electric push rod 9. The ends of the connecting strip 10 are respectively fixedly mounted to the protective frames 8.
[0025] In the shielded waterproof Pogo Pin assembly, the needle shaft 1 serves as the core support structure of the assembly, used to carry current conduction and position the various components. The spring built into it can provide elastic restoring force to ensure that the needle tube 2 can achieve stable extension and retraction during insertion and removal. The needle tube 2 is slidably sleeved on the outside of the needle shaft 1, which not only protects the conductive area of the needle shaft 1, but also realizes the switching on and off of electrical connection through sliding. The tail needle 3 is fixed at the end of the needle shaft 1 to establish a stable connection with the internal circuit of the device.
[0026] When the component is not in operation, the electric push rod 5 fixed on the disc 4 at the end of the needle shaft 1 is activated. Its output shaft drives the ring 6 fixed to it to slide horizontally along the needle shaft 1. The support rod 7 on the ring 6 moves synchronously. The electric push rod 9 installed on the support rod 7 adjusts its position accordingly. Then, the electric push rod 9 drives the output shaft to push the connecting strip 10. The connecting strip 10 drives the symmetrical protective frames 8 on both sides of the needle tube 2 to close. The rubber frame on the inner wall of the protective frame 8 fits tightly with the needle tube 2, achieving full shielding of the needle shaft 1 and the needle tube 2. When working, the electric push rod 9 first drives the protective frame 8 to open. The electric push rod 5 drives the ring 6 and the support rod 7 to reset. Under the action of the external plug, the needle tube 2 compresses the spring and slides along the needle shaft 1, exposing the conductive area of the needle shaft 1 and contacting the plug. After completing the electrical connection, the electric push rod is activated in reverse to restore the shielding state. Automatic protection and stable conductivity are achieved through the cooperation of various components.
[0027] This shielded waterproof Pogo Pin assembly can automatically shield and protect the pin shaft 1 when not in use, improving waterproof performance, extending service life, and making it highly practical.
[0028] The inner diameter of the protective frame 8 is compatible with the size of the needle tube 2;
[0029] The inner diameter of the protective frame 8 is matched with the size of the needle tube 2, which can improve the stability of the protection of the needle tube 2.
[0030] The inner diameter of the ring 6 is matched with the outer diameter of the needle shaft 1;
[0031] The inner diameter of the ring 6 is matched with the outer diameter of the needle shaft 1, which can improve the stability of the horizontal movement of the ring 6.
[0032] Both electric actuator 1.5 and electric actuator 2.9 are designed to be miniature.
[0033] Both electric linear actuator 1.5 and electric linear actuator 2.9 are designed to be miniature, taking up little space.
[0034] Both electric push rod 1 (5) and electric push rod 2 (9) are set to self-locking type;
[0035] Both electric push rod 5 and electric push rod 9 are self-locking, which can further improve the stability of the protective frame 8.
[0036] Working principle:
[0037] In the shielded waterproof Pogo Pin assembly, the needle shaft 1 serves as the core support structure of the assembly, used to carry current conduction and position the various components. The spring built into it can provide elastic restoring force to ensure that the needle tube 2 can achieve stable extension and retraction during insertion and removal. The needle tube 2 is slidably sleeved on the outside of the needle shaft 1, which not only protects the conductive area of the needle shaft 1, but also realizes the switching on and off of electrical connection through sliding. The tail needle 3 is fixed at the end of the needle shaft 1 to establish a stable connection with the internal circuit of the device.
[0038] When the component is not in operation, the electric push rod 5 fixed on the disc 4 at the end of the needle shaft 1 is activated. Its output shaft drives the ring 6 fixed to it to slide horizontally along the needle shaft 1. The support rod 7 on the ring 6 moves synchronously. The electric push rod 9 installed on the support rod 7 adjusts its position accordingly. Then, the electric push rod 9 drives the output shaft to push the connecting strip 10. The connecting strip 10 drives the symmetrical protective frames 8 on both sides of the needle tube 2 to close. The rubber frame on the inner wall of the protective frame 8 fits tightly with the needle tube 2, achieving full shielding of the needle shaft 1 and the needle tube 2. When working, the electric push rod 9 first drives the protective frame 8 to open. The electric push rod 5 drives the ring 6 and the support rod 7 to reset. Under the action of the external plug, the needle tube 2 compresses the spring and slides along the needle shaft 1, exposing the conductive area of the needle shaft 1 and contacting the plug. After completing the electrical connection, the electric push rod is activated in reverse to restore the shielding state. Automatic protection and stable conductivity are achieved through the cooperation of various components.
[0039] This shielded waterproof Pogo Pin assembly can automatically shield and protect the pin shaft 1 when not in use, improving waterproof performance, extending service life, and making it highly practical.
