Abstract
A space-saving module is provided. The utility model relates to the technical field of electronics, and especially relates to a space-saving optical module. According to the novel space-saving optical module, in order to reduce the use area that the optical module occupies on a PCB, simplify the structure and reduce the cost, two aspects are taken into consideration: the PCBA inside the optical module is canceled, and all the components are moved to a large board. As a result, the area that the components occupy on the PCB is reduced, and the utilization ratio of the PCB is improved. The space-saving optical module comprises a base, an upper cover, a BOSA, a metal housing and a dust-proof plug, wherein the BOSA and the dust-proof plug are disposed on the base; the upper cover is disposed on the BOSA; and the metal housing is disposed on the upper cover. Through the direct connection of the nine pins of the BOSA and the large board, the complex welding process in conventional optical modules is simplified. The space-saving optical module is smart in structure design and simple in structure, and is stable and reliable. With the space-saving optical module, the utilization ratio of PCBs can be effectively improved and the cost of products can be reduced. According to the space-saving optical module, the internal structure of a conventional optical module is optimized; the internal circuit boards of the conventional optical module are reduced; the length of the product is shortened, the space of the main board is increased, and the cost is lowered.
Description
Technical field
The utility model relates to electronic technology field, relates in particular to a kind of conserve space optical module.
Background technology
Along with the develop rapidly that the city light net is built, light advances copper and moves back the epoch arrival.Demand to optical mode plate is increasing.Optical module for traditional plug-in is made up of base, loam cake, BOSA, PCBA, PIN, metal shell, dust plug, and its complex structure, size are big, cost is higher, and it is bigger to account for the projected area of PCB.Tradition plug-in optical module is the welding through BOSA and PCBA, is connected with big plate through 20 PIN pin and realizes the signal transmission, and shortcoming rosin joint occurs for needing only a place, and product needed is reprocessed or scrapped.Also have the inner PCBA of optical module because area is less, and the device that uses all is paster spare, cost and technological requirement are all high.
The utility model content
The above-mentioned deficiency that the utility model exists to prior art; Novel a kind of conserve space optical module is provided; Reduce cost at the usable floor area of PCB and the simplification of structure in order to reduce optical module; New optical module is considered from two aspects: the inner PCBA of cancellation optical module all moves on to all devices on the big plate.Reduce the area of device on PCB, improve the utilization factor of PCB.
The purpose of the utility model is to realize through following technical scheme:
A kind of conserve space optical module comprises base, loam cake, BOSA, metal shell, dust plug, and said base is provided with BOSA and dust plug, and said BOSA is provided with loam cake, covers on said and is provided with metal shell.
The utility model beneficial effect: 9 PIN through BOSA directly are connected with big plate, have simplified the middle loaded down with trivial details welding technology of traditional optical module.Structural design is ingenious, and is simple for structure, reliable and stable, effectively improves the utilization factor and reduction cost of products of PCB.The present invention has optimized traditional optical module inner structure, has reduced the internal circuit board of optical module.Shorten the length of product, improved the space of mainboard, reduced cost.
Description of drawings
Fig. 1 is traditional plug-in optical mode plate structural representation.
Fig. 2 is the described conserve space optical module of a utility model structural representation.Among the figure:
The 1-base; The 2-loam cake; 3-BOSA; The 4-metal shell; The 5-dust plug; 6-PCBA; 7-PIN.
Embodiment
According to accompanying drawing and embodiment the utility model is done further explain below.
Like Fig. 1, shown in Figure 2; A kind of conserve space optical module of the utility model comprises base 1, loam cake 2, BOSA3, metal shell 4, dust plug 5, novel a kind of conserve space optical module; On base 1, be provided with BOSA3 and dust plug 5; Dust plug 5 plays and prevents that dust from getting into the effect in the module, and said BOSA3 is provided with loam cake 2, and said loam cake 2 is provided with metal shell 4.Novel conserve space optical module has lacked PCBA6 and two parts of PIN7 than traditional plug-in optical mode plate structure, all moves on to all devices on the big plate of BOSA3, and the projected area that accounts for PCB is by original 654mm
2Reduce to 469mm
2, reduce the area of device on PCB, improve the utilization factor of PCB.Traditional plug-in unit optical module is connected with big plate through 20 PIN pin and realizes the signal transmission through the welding of BOSA and PCBA, and shortcoming is that product needed is reprocessed or scrapped as long as rosin joint appears in a place.And novel plug-in unit optical mode plate has changed this situation, and 9 PIN through BOSA3 directly are connected with big plate, has simplified loaded down with trivial details welding technology in the middle of traditional optical module, uses more convenient.
