Abstract
A kind of many quadrant detection device assemblies of flat structure, including base, pcb board, ceramic substrate, photosensor chip, light window and pipe cap；Advantageous Effects of the present utility model are：A kind of many quadrant detection device assemblies of flat structure are provided, the axial width of many quadrant detection device assemblies is relatively thin.
Description
Technical field
This utility model is related to a kind of many quadrant detection device assemblies, more particularly to a kind of many quadrant detectors of flat structure
Component.
Background technology
Many quadrant detectors can regard multiple photodetectors as, and each quadrant constitutes a photodetector, therefore needs
Amplifying circuit to be equipped with individually for each quadrant, in prior art, a kind of typical structure：Arrange on base upper surface convex
Platform, the polylith circuit board of corresponding multiple quadrants are mounted in the circumferential side wall of boss, and photosensor chip is arranged on the upper surface of boss
On；The problem of presence is：As circuit board is mounted in the circumferential side wall of boss, therefore boss must possess necessary axially long
Degree, and in some particular applications, have strict demand to the axial width of many quadrant detectors, using existing structure form,
The axial length of boss must is fulfilled for the attachment requirement of circuit board, causes the axial width of many quadrant detectors to be difficult to further contract
Subtract.
Utility model content
Problem in for background technology, the utility model proposes a kind of many quadrant detection device assemblies of flat structure,
Its structure is：Many quadrant detection device assemblies include base, pcb board, ceramic substrate, photosensor chip, light window and pipe cap；Institute
State, in the middle part of circular groove cell wall, be provided with step surface, circular groove bottom land
Middle part is provided with a boss, is provided with blind hole on base lower surface, and the position of blind hole is relative with circular groove；The pcb board
Outline is mated with the outline of circular groove, and the middle part of pcb board arranges the square hole mated with boss, and pcb board is socketed in boss
Outward, the neighboring edge of pcb board lower surface is contacted with the upper surface of step surface；The outline of the ceramic substrate and the upper end of boss
Face is mated, and ceramic substrate is arranged on the upper surface of boss, and photosensor chip is arranged on the upper surface of ceramic substrate；The pipe cap
Lower surface and base upper surface neighboring along being connected, be provided with the installing hole mated with light window, light window in the middle part of pipe cap
It is arranged in installing hole；Multichannel amplifying circuit is integrated with the pcb board, and multichannel amplifying circuit is corresponded on photosensor chip respectively
Multiple quadrants.During concrete application, pin is arranged on base lower surface in the region of corresponding circular groove.
In this utility model, the multichannel amplifying circuit of corresponding multiple quadrants is integrated on one piece of pcb board, pcb board
Profile is the disk with square hole, constitute on pcb board circuit various elements and circuit be distributed in perpendicular to detector axis to flat
On face, this boss allowed on base no longer needs to provide installing space for circuit board, can significantly reduce the axial direction of boss
Length, finally allows detector to obtain less axial width.In addition, pcb board is supported by step surface, step surface and boss
Gap between the wall of side makes the lower surface of pcb board hanging, is conducive to the radiating of pcb board.
Preferably, the quadrant quantity of the photosensor chip is four.
Preferably, the circumferential profile of the boss is square.
Advantageous Effects of the present utility model are：A kind of many quadrant detection device assemblies of flat structure are provided, this is more
The axial width of quadrant detection device assembly is relatively thin.
