The utility model discloses an useful technological effect is: can effectively improve the shock resistance of light detector module.
Description
Technical field
This utility model relates to a kind of photo-detector, particularly relates to the photo-detector module of a kind of high impact-resistant overload.
Background technology
Along with the progress of technology, the application of photo-detector is more and more extensive, in some application, it is desirable to photo-detector possesses higher shock resistance overload capacity, and common photo-detector encapsulating structure is difficult to be competent at.
Utility model content
For the problem in background technology, the utility model proposes the photo-detector module of a kind of high impact-resistant overload, including shell and base, it is improved by: is provided with light fenestra in the middle part of described shell, is provided with light window in light fenestra；By the conical surface transition of evagination between light fenestra edge and shell circumferential side wall, the conical surface being provided with a plurality of reinforcement, the upper surface of reinforcement and plane-parallel, a plurality of reinforcement is uniformly distributed along shell circumference；The edge of base upper surface is provided with the ring-shaped step mated with shell lower end, and shell lower end is fixing with ring-shaped step to be connected；It is provided with boss in the middle part of base, between boss upper surface and light window, leaves gap, between circumferential side wall and the inner wall of tube shell of boss, leave gap；Multiple pin hole it is provided with in region between base upper surface convex platform and shell；Base lower surface is provided with the shrinkage pool mated with boss.
During encapsulation, photo detector chip is arranged on the upper surface of described boss, circuit board is arranged in described shrinkage pool, and amplifier adopts thick film hybrid and is attached in the circumferential side wall of boss, and the lead-in wire of photo detector chip is outwards drawn by the pin being arranged in pin hole.When withstanding shocks, impact stress can be distributed on shell sidewall by the conical surface, reduces the deformation of optical window surrounding structure, optical window is played a protective role, and reinforcement can be effectively improved the structural strength in conical surface region.
Advantageous Effects of the present utility model is: can be effectively improved the impact resistance of photo-detector module.
