Description

The optical module indicator lamp go out the lamp device

Technical field

The utility model relates to the communications field, goes out the lamp device in particular to a kind of optical module indicator lamp.

Background technology

At present, on the optical communication product of electronics or communication field, the next door of optical module need be provided with indicator lamp, is used to indicate the work running status of optical module.Please refer to Fig. 1; Generally, the lamp device that goes out of optical module is fixed on the veneer that is assembled by panel and PCB (Printed Circuit Board, printed circuit board (PCB)); Go out lamp device and optical module and all be arranged on veneer PCB front, go out lamp device and optical module layout side by side.(in Fig. 1, Reference numeral is: veneer 10, panel 12, PCB14, optical module 16, go out lamp device 18).But this mode only takes it easy in veneer PCB layout, and has enough spaces to be used to set out under the prerequisite of lamp device just can to realize; Nowadays; Along with increasing substantially of veneer PCB capacity, the integrated level of veneer requires increasingly high, and then causes the layout of veneer PCB more and more nervous; Behind the optical module of having arranged, do not had the space and set out the lamp device again.Because cun plank inch gold of the space on the veneer PCB, the limitation of above-mentioned layout type is very big, simultaneously, under this layout type, goes out that leaded light post in the lamp device is not easy to assemble to cause maintainability relatively poor.

Lamp device and the optical module coplanar problem of layout is side by side used in enough spaces that do not have to the positive layout anxiety of veneer PCB causes; A kind of improved mode be with optical module still layout in the front of veneer PCB; And will go out the back side that the lamp device is fixed on veneer PCB; Concrete set-up mode sees also Fig. 2 (in Fig. 2, Reference numeral is: veneer 20, panel 22, PCB24, optical module 26, go out lamp device 28, the top among Fig. 2 is the back side layout of PCB, the positive layout that the bottom is PCB).Though this mode can be for optical module provides the lamp device under the situation of veneer PCB layout anxiety, the shortcoming of this mode is: the back side height space of veneer PCB is limited, when assembling; The leaded light post that goes out in the lamp device is easy to squeeze wound or bumps the light emitting source on the PCB; Simultaneously, go out that leaded light post in the lamp device is not easy to assemble to cause maintainability poor, and; Owing to need can cause the volume production weak effect of veneer PCB in the two-sided layout of carrying out of PCB.

To in the correlation technique under the nervous situation of veneer PCB layout, the irrational problem of the layout type that sets out the lamp device of employing does not propose effective solution at present as yet.
