Description

Technical Field

[0001] This utility model relates to the field of SiC ultraviolet sensor technology, and in particular to a protection structure for SiC ultraviolet sensors. Background Technology

[0002] Silicon carbide (SiC) is a third-generation wide-bandgap semiconductor material with a bandgap of 3.26 eV and a cutoff wavelength of 380 nm. It has advantages such as high thermal conductivity and strong radiation resistance. It is unresponsive to visible light, making it an ideal material for fabricating high-performance ultraviolet sensors. SiC ultraviolet sensors have advantages such as small size, high sensitivity, strong resistance to visible light interference, low power consumption, and high reliability. SiC ultraviolet sensors have excellent high-temperature stability and low leakage current characteristics, and can work in high-temperature environments for a long time. The operating temperature of SiC ultraviolet sensor chips can exceed 400°C, making them particularly suitable for extreme industrial environments.

[0003] The existing technical solutions mentioned above have the following drawbacks: the internal components of the existing sensors lack external protective structures, and the protection effect of the encapsulated shell structure on the sensor components themselves is limited, resulting in insufficient practicality. Utility Model Content

[0004] The purpose of this invention is to provide a protective structure for SiC ultraviolet sensors.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A protective structure for a SiC ultraviolet sensor includes a SiC ultraviolet sensor body. A first rubber pad is fitted onto one side of the outer surface of the SiC ultraviolet sensor body, and a second rubber pad is provided on the other side of the outer surface of the SiC ultraviolet sensor body. A first locking block is provided at one end of the outer surface of the SiC ultraviolet sensor body. A locking groove is formed inside the first locking block, and a buffer ring is engaged inside the locking groove. A limiting hole is reserved on the outer surface of the first locking block, and a locking seat is fixedly connected to the outer surface of the first locking block. A second locking block is provided at the other end of the outer surface of the SiC ultraviolet sensor body.

[0007] By adopting the above technical solution, two sets of rubber pads are added to the outside of the sensor. When the sensor and the card block are engaged, the rubber pads are engaged together with the inside of the card block. This can improve the sealing of the two connection points between the card block and the sensor. At the same time, the rubber structure can prevent the card block from rotating along the outside of the sensor, increase the friction of the contact surface, and improve the stability of the structure.

[0008] Furthermore, the second card block has the same card slot and buffer ring inside. A limit block is fixedly connected to the outside of the second card block. The same card seat is fixedly connected to the outside of the second card block. The card seat has external threads on its outside. A through hole is opened in the center of the inside of the card seat. An installation groove is reserved on the outside of the card seat. A buffer block is fixedly connected to the inside of the card seat. A high light transmittance cover plate is engaged inside the installation groove. A protective cover is provided on the outside of the card seat. The protective cover has internal threads inside.

[0009] By adopting the above technical solution, a highly transparent cover plate is added to the outside of the protective cover, which can protect the sensor without affecting its use.

[0010] Furthermore, the outer side of the SiC ultraviolet sensor body is engaged with the inside of the buffer ring, the first rubber pad and the second rubber pad are respectively attached to the end face of the outer side of the SiC ultraviolet sensor body, and the first rubber pad and the second rubber pad are both engaged with the inside of the slot. The first and second locking blocks are the same size and have the same specifications.

[0011] By adopting the above technical solution, and by adding two sets of identical card blocks, the two sets can be docked and locked directly onto the outside of the sensor to protect the sensor.

[0012] Furthermore, two symmetrically arranged limiting holes and limiting blocks are provided. The limiting blocks are inserted into the limiting holes and engaged with them. Two sets of the card seats, external threads, through holes, mounting grooves, and buffer blocks are provided. Multiple buffer blocks are provided in each set. The two sets of card seats fit tightly together.

[0013] By adopting the above technical solution, by adding limiting holes and limiting blocks between the two sets of blocks, the stability of the installation structure can be improved through the insertion of the limiting blocks and limiting holes. First, the insertion and locking are performed, and then the connection and fixation are achieved through the protective cover.

[0014] Furthermore, the external and internal threads are threaded together, the buffer block is in contact with the outer side of the SiC ultraviolet sensor body, and the inner side of the protective cover is in contact with the outer side of the high-transmittance cover plate.

[0015] By adopting the above technical solution, the high-transmittance cover plate can be fixed by pressing it with the protective cover, which facilitates installation and fixation.

[0016] In summary, the beneficial technical effects of this utility model are as follows:

[0017] The system employs a first locking block, a second locking block, rubber pads, a buffer ring, a buffer block, a protective cover, and a high-transmittance cover plate. Two identical locking block structures are added to the outside of the sensor, along with two sets of rubber pads. The rubber pads seal the connection between the locking block and the sensor, improving the tightness of the connection. A buffer block is added inside the locking base to protect the outside of the sensor. The two sets of locking blocks are then locked and fixed using the protective cover and threaded connections, achieving protection for the outside of the sensor. The structure can be assembled and spliced, resulting in convenient installation, use, and efficient protection. Attached Figure Description

The buffer blocks 12 are attached to the outer side of the SiC UV sensor body 1. The inner side of the protective cover 15 is attached to the outer side of the high light transmittance cover plate 14.

[0029] The implementation principle of this embodiment is as follows: First, two sets of rubber pads are added to the outside of the SiC ultraviolet sensor body 1. Then, the SiC ultraviolet sensor body 1, together with the rubber pads, is snapped into the slot 5 and buffer ring 6 inside the first snap block 4. Then, the other side of the SiC ultraviolet sensor body 1 is snapped into the same slot 5 and buffer ring 6 inside the second snap block 13.
