Description

Technical Field

[0001] This invention relates to the field of diode technology, specifically to a high-reliability, ultra-small, high-speed switching surface-mount diode structure. Background Technology

[0002] With the continuous development of society, surface-mount diodes are required for the installation and use of ultra-miniature high-speed switches. These are electronic devices with unidirectional current conduction. Inside a semiconductor diode is a PN junction with two leads. This type of electronic device exhibits unidirectional current conduction according to the direction of the applied voltage. Generally speaking, a surface-mount crystal diode is a pn junction interface formed by sintering p-type and n-type semiconductors. A space charge layer is formed on both sides of this interface, creating a built-in electric field. When the applied voltage is zero, the diffusion current caused by the concentration difference of charge carriers on both sides of the pn junction and the drift current caused by the built-in electric field are equal, resulting in an electrical equilibrium state. This is the characteristic of a diode under normal conditions.

[0003] During operation, diodes may vibrate or move, which reduces their stability. They also generate diffusion current and drift current caused by their built-in electric field, making them prone to internal damage. Furthermore, they may have insufficient data transmission capability, reducing their reliability. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, this application aims to provide a high-reliability, ultra-small, high-speed switching surface-mount diode structure, including a surface-mount diode body, pins at the bottom left and right ends of the surface-mount diode body, a limiting rod inside the surface-mount diode body, a positioning plate on the side of the limiting rod, a push plate at the bottom of the positioning plate, a reinforcing strip on the side of the push plate, a screw at the bottom of the reinforcing strip, a nut at the top of the screw, a pad on the side of the screw, a sealing plate on the side of the pad, and an adjustment hole inside the sealing plate.

[0005] Preferably, the pins are symmetrically mounted on the left and right ends of the bottom of the surface mount diode body.

[0006] Preferably, the limiting rod is fixedly installed on the inner wall of the surface mount diode, the positioning plate is fixedly installed on one side of the limiting rod, and the push plate is installed on the lower surface of the positioning plate.

[0007] Preferably, the reinforcing strip is fixedly installed on one side of the push plate, the screw is threadedly connected to the lower surface of the reinforcing strip, and the nut is threadedly connected to the upper surface of the screw.

[0008] Preferably, the pad is fixedly installed on one side of the screw.

[0009] Preferably, the sealing plate is fixedly installed on one side of the pad, and the adjustment hole is opened on the inner wall of the sealing plate. Beneficial effects

[0010] 1. This high-reliability, ultra-small, high-speed switching surface-mount diode structure enhances the safety and stability of the surface-mount diode's switching by installing a limiting rod. When the push plate vibrates or moves during operation, the positioning plate prevents the push plate from moving during use and effectively fixes it, allowing the surface-mount diode to function stably. At the same time, it prevents the surface-mount diode from generating diffusion current and drift current caused by the self-built electric field, which could easily damage the internal structure of the surface-mount diode, thereby enhancing the stability of the surface-mount diode.

[0011] 2. This high-reliability, ultra-miniature, high-speed switching surface-mount diode structure, through the installation of a sealing plate, prevents leakage of the surface-mount diode body when transmitting current, and prevents external impurities, dust, and moisture from infiltrating and damaging the surface-mount diode body, thus providing a certain degree of protection. At the same time, through the installation of the adjustment hole, when the surface-mount diode body is transmitting data, if the data transmission capacity is insufficient, the operating status of the surface-mount diode body can be adjusted through the adjustment hole, avoiding excessive resource consumption, thereby improving the reliability of the surface-mount diode body.

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0018] The accompanying drawings in this embodiment of the invention: The different types of cross-sectional lines in the drawings are not labeled according to national standards, nor do they specify the material requirements of the components. They are used to distinguish the cross-sectional views of the components in the drawings.

[0019] Please see Figure 1-3 A high-reliability, ultra-small, high-speed switching surface-mount diode structure includes a surface-mount diode body 1, pins 2 at the bottom left and right ends of the surface-mount diode body 1, a limiting rod 3 inside the surface-mount diode body 1, a positioning plate 4 on the side of the limiting rod 3, a push plate 5 at the bottom of the positioning plate 4, a reinforcing strip 6 on the side of the push plate 5, a screw 7 at the bottom of the reinforcing strip 6, a nut 8 at the top of the screw 7, a pad 9 on the side of the screw 7, a sealing plate 10 on the side of the pad 9, and an adjustment hole 11 inside the sealing plate 10.

[0020] Pin 2 is mounted on the bottom of the surface mount diode body 1 to improve the receiving capability of the surface mount diode body 1. At the same time, pin 2 can be used to enter the internal frequency modulation demodulation circuit for demodulation in an unbalanced manner. Pin 2 enables the resistor to receive a high-level signal. When no signal is received, pin 2 presents a low impedance and outputs a low level.

[0021] The installation of the limiting rod 3 enhances the safety and stability of the surface mount diode body 1 switch. When the push plate 5 vibrates or moves during operation, the positioning plate 4 prevents the push plate 5 from moving during use and effectively fixes it, so that the surface mount diode body 1 can function stably. At the same time, it prevents the surface mount diode body 1 from causing diffusion current and drift current caused by the self-built electric field, which would easily damage the inside of the surface mount diode body 1, thereby enhancing the stability of the surface mount diode body 1.

[0022] The installation of the reinforcing strip 6 prevents the surface mount diode body 1 from deforming under impact, making the surface mount diode body 1 more stable during use and thus playing a reinforcing role. At the same time, the cooperation of the screw 7 and nut 8 makes it difficult for the reinforcing strip 6 to fall off from the surface mount diode body 1, and facilitates the installation and disassembly of the personnel, greatly improving the reliability of the surface mount diode body 1.

[0023] The installation of the pad 9 ensures the overall stability of the surface mount diode 1, reduces the impact on the use of the surface mount diode 1, and the pad 9 also has a certain ability to withstand external forces, enabling the surface mount diode 1 to operate quickly. At the same time, it allows the internal components of the surface mount diode 1 to be tightly connected, thereby effectively controlling the surface mount diode 1.

[0024] The sealing plate 10 serves to prevent leakage of the surface mount diode 1 when transmitting current, and to prevent external impurities, dust, and moisture from entering and damaging the surface mount diode 1, thus providing a certain degree of protection. Simultaneously, the adjustment hole 11 allows for adjustment of the surface mount diode 1's operating status when its data transmission capacity is insufficient, preventing excessive resource consumption and improving its reliability.

[0025] During use, the installation of the limiting rod 3 enhances the safety and stability of the surface mount diode body 1 switch. When the push plate 5 vibrates or moves during operation, the positioning plate 4 prevents the push plate 5 from moving during use and effectively fixes it, so that the surface mount diode body 1 can function stably.

[0026] At the same time, it prevents the surface mount diode body 1 from causing diffusion current and drift current caused by the self-built electric field, which would easily damage the surface mount diode body 1. This enhances the stability of the surface mount diode body 1. The installation of the sealing plate 10 prevents leakage when the surface mount diode body 1 is transmitting current, and prevents external impurities, dust and moisture from entering and causing damage to the surface mount diode body 1. It also plays a certain protective role.

[0027] Meanwhile, by installing the adjustment hole 11, when the surface mount diode 1 is transmitting data, if the data transmission capability is insufficient, the operating status of the surface mount diode 1 can be adjusted by adjusting the adjustment hole 11 to avoid excessive resource consumption, thereby improving the reliability of the surface mount diode 1.
