This creation is an improvement of the structure of the endoscope end cover combined with the sensor. A functional groove is provided on the outer edge of the combined hole of the endoscope end cover to prevent the sensor from being scratched during the assembly process. And, by increasing the area of bonding, improving its combined strength and waterproof effect, and using the inverted L-shaped bonding surface to increase the function of preventing static electricity, avoiding damage to the sensor and achieving practical progress.本創作為一種內視鏡端面蓋結合感應器之結構改良，係於內視鏡端面蓋之組合孔的外緣設置一環功能性溝槽，使感應器於組裝過程時，可避免鏡頭的碰傷，並藉由增加膠合的面積，提高其組合強度和防水效果，且利用呈倒L狀的膠合面，增加防止靜電功能，避免感應器受損害，獲致實用進步性者。
