Common SFF optical module structure integrated with sending and receiving is complicated, and part constitutes more complicated, assemble loaded down with trivial details, the production cost height.The common SFF integrated module of optical transceiver is generally by a lower cover, a shell, a BOSA (single fiber bi-directional assembly), a PCBA (circuit board), two row's pins, a fixing BOSA briquetting, shell formation.Common SFF integrated module of optical transceiver lower cover adopts Zinc alloy die-casting process, needs aftertreatment technologys such as sandblast plating behind the casting forming, and life cycle of the product is longer, and die casting simultaneously and electroplating technology control difficult point are many, and fraction defective is higher relatively.Generally speaking, adopt the lower cover of traditional zinc alloy diecasting, the production cycle is longer, and cost is higher, and is defective higher relatively.
The inventor designs and develops out a single fiber bi-directional SFF integrated module of optical transceiver simple in structure, easy to assembly through research and experiment, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of single fiber bi-directional SFF integrated module of optical transceiver, and structural member is few, and assembling is easy, and cost is low, the reliability height.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of single fiber bi-directional SFF integrated module of optical transceiver comprises loam cake, lower cover, a PCBA, a BOSA; Under be covered with square groove, the last respective slot of PCBA has the protruding wing and carries out button bit, the protruding wing snaps in groove and realizes the BOSA location; Lower cover also is provided with cramp simultaneously, and the corresponding cramp of loam cake is provided with corresponding hole site, and cramp buckles into the installing and locating that loam cake is realized in the position, hole.
Described groove has three places, is laid in the both sides and the rear end of lower cover respectively, realizes the reliable location of PCBA.
Described cramp is a triangle, and corresponding button hole also is a triangle.
Described PCBA is provided with row's pin hole of the row's of installation pin, is used to arrange location and the welding of pin on PCBA, and the PCBA front end is provided with pad, and the stitch of PCBA is welded on the pad, is provided with the perforate of the row's of dodging pin stitch simultaneously in the bottom of lower cover.
Described row's pin plastic cement bottom is provided with the small boss of the row's of preventing pin and lower cover contact short circuit.
Described lower cover bottom is provided with the square convex closure that is used to support the BOSA bottom.
Described loam cake and lower cover front end are provided with semicircular opening, to dodge BOSA.
Described loam cake bottom is provided with pilot hole, and pilot hole is installed the angle with shell location, riveted joint.
Described loam cake, lower cover are by the integrated parts of metal plate punching.
The technical solution of the utility model, the more traditional transceiver module of structure is few, and is simple in structure, installs quick and convenient.Upper and lower covers adopts metal plate punching technology entirely, and processing and material cost reduce much than the system mode, and stainless steel parts need not postprocessing working procedures, and the production cycle greatly reduces.It is more succinct and reliable that described triangle cramp and protruding wing button bit, more traditional briquetting compress locator meams.In addition, the design of stitch small boss effectively prevents the stitch short circuit, and the convex closure of lower cover bottom makes the square matrix of BOSA stablize fixing more, strengthens the fastness of its installation.

Embodiment
As shown in Figure 2, present embodiment comprises loam cake 1, PCBA 2, BOSA 3, row's pin 4 and the lower cover 5 of optical transceiver module.
As Fig. 5, lower cover 5 is to be mainly used in the fixedly main basis of remaining part, and its both sides and afterbody are provided with the recessed shaping in three places, is provided with three prescription connected in stars 51 in recessed shaping place, and lower cover 5 both sides are provided with triangle cramp 52 everywhere simultaneously.Be provided with the square convex closure 54 of support BOSA and the perforate 56 of the row's of dodging pin in the bottom of lower cover 5, the outer riveted joint in bottom has angle 55 simultaneously, and the lower cover front end is provided with semicircular opening 53 for dodging BOSA.
As Fig. 4, loam cake 1 is the covering of this integrated module of optical transceiver, and its both sides are provided with and the corresponding delthyrium of lower cover position 11, and front end is provided with semicircular opening 12 for dodging BOSA.
As Fig. 3, PCBA2 is for connecting the basis of BOSA3 and row's pin 4, the row's of which is provided with pin hole 22, location and welding for row's pin 4, the corresponding lower cover groove 51 in both sides and rear end is provided with the protruding wing 21 in three places, and the PCBA2 front end has two place's pads 23, is welded thereon by the pin on the BOSA 3 31, realize the connection of BOSA3, the matrix bottom of BOSA3 is supported by the square convex closure on the lower cover 5 54.Cause short-circuit risks for the row's of avoiding pin 4 contacts with lower cover 5 bottoms row's pin hole 22, be provided with circular small boss 41 at the plastic cement position of row's pin 1 for this reason.
