Abstract
The utility model discloses a single-fiber optical transceiver, which comprises a plastic base, a metal plate shell and an optical transceiver device, wherein the optical transceiver device is installed in a hollow cavity formed by the plastic base and the metal plate shell after match, and a PCB (Printed circuit board) circuit board is connected on the optical transceiver device. A bending convex lug for fixing the PCB circuit board is arranged on the side wall of the metal plate shell, and the bending convex lug is of an inward bending shape. The single-fiber optical transceiver cancels the traditional plastic hook but adopts the bending convex lug arranged on the inner side surface of the metal plate shell to fix the PCB circuit board, and the bending convex lug and the metal plate shell are integrally molded, so that the problem that the plastic hook is adopted in the prior art and the plastic hook is easily broken is solved.
Description
Technical field
The utility model relates to the electrooptical device field in fiber data communication and the telecom communication, particularly a kind of single fiber optical transceiver module.
Background technology
The structure of single fiber optical transceiver module of the prior art is to make according to the multi-source agreement of SFF module basically, mainly is made up of plastic feet, panel beating shell and optical transceiving device, and optical transceiving device is positioned between plastic feet and the plastics locator card; And at optical transceiving device outer panel beating shell spare; Be connected with the PCB circuit board on the optical transceiving device, PCB circuit board level horizontally set, the one of which end is connected with optical transceiving device; Be the semi-girder state, at this moment need fix the PCB circuit board; And be the plastics grab to be set at the A place of plastic feet the PCB circuit board is fixed (referring to Fig. 1) in the prior art; But this plastic clip is hooked in the long-term use and fractures easily; Make its fixed effect receive influence, cause fraction defective higher the PCB circuit board.And in the prior art, plastic feet and panel beating shell spare only are that the inwall of side and the panel beating shell spare of plastic feet is fitted after assembling, can occur fitting not firm and the situation of pine occurs cooperating usually like this, and then have influence on the use of single fiber optical transceiver module.
The utility model content
The utility model first aspect is to solve available technology adopting plastics grab and the plastics grab to occur easily broken, thereby causes the effectively fixedly problem of PCB circuit board.
To achieve these goals; The technical scheme that the utility model adopts is such: a kind of single fiber optical transceiver module; Comprise plastic feet, panel beating shell and optical transceiving device, optical transceiving device is installed in plastic feet and cooperates with the panel beating shell in the formed cavity in back, is connected with the PCB circuit board on the optical transceiving device; The sidewall of said panel beating shell is provided with the lug that bends that is used for fixing the PCB circuit board, and this lug that bends is inside bending-like.Said lug and the panel beating shell of bending is one-body molded.
Loosening problem appears in further solution plastic feet of the present invention and panel beating shell spare assembling back easily; For this reason in the technical scheme of the utility model; The bottom surface of said plastic feet is provided with notch, and the panel beating shell is provided with and the corresponding sheet metal of said notch position.Said sheet metal and panel beating shell are one-body molded.
As preferably, said sheet metal is arranged on the left and right side of panel beating shell.Said plastic feet is with after the panel beating shell cooperates, and sheet metal is buckled in notch by bending.
Compared with prior art, the advantage of the utility model is:
1, the utility model has been cancelled former plastic cement grab; The lug that bends is set on the medial surface of panel beating shell spare the PCB circuit board is fixed then be employed in; This bend lug and panel beating shell spare are one-body molded, have solved available technology adopting plastics grab and the easily broken problem of plastics grab occurs.
2, after the assembling of plastic feet in the utility model and panel beating shell spare; Buckle in the notch of plastic feet bottom through the sheet metal bending on the panel beating shell spare; Can plastic feet and panel beating shell spare be fixed in one tightly, solve plastic feet and the loosening problem of panel beating shell spare assembling back appearance in the prior art.

Embodiment
To combine accompanying drawing and practical implementation that the utility model is described further below;
Referring to 2 to Fig. 6; A kind of single fiber optical transceiver module; Comprise plastic feet 1, panel beating shell 2 and be arranged on the light mouth 6 and the optical transceiving device 3 of box body front end; Optical transceiving device 3 is fixedly mounted on plastic feet 1 through plastics fixed card 7 and cooperates with panel beating shell 2 in the formed cavity in back, is connected with PCB circuit board 4 on the optical transceiving device 3, is arranged on two gold-plated row's pins 8 on the PCB circuit board 4 and passes plastic feet 1 and stretch out outside the optical transceiver module.The sidewall of panel beating shell 2 is provided with and the corresponding lug 2-2 that bends in PCB circuit board 4 installation sites, and this bend lug 2-2 and panel beating shell 2 are one-body molded and be inside bending-like, and the lug 2-2 that bends is used for fixing PCB circuit board 4; The lug 2-2 that bends can play the same fixation of plastics grab 5 (referring to Fig. 1) with existing transceiver module; And the lug 2-2 that bends is a metal material; Durable in use; Behind the A place of plastic feet 1 cancellation plastics grab 5, increased the installing space of optical transceiving device 3, and simplified the processing technology of plastic feet 1.The bottom surface of said plastic feet 1 is provided with notch 1-1, and the left and right side of panel beating shell 2 is provided with and the corresponding sheet metal 2-1 in said notch 1-1 position, and this sheet metal 2-1 and panel beating shell 2 are one-body molded.Plastic feet 1 is with after panel beating shell 2 cooperates, and sheet metal 2-1 is buckled in notch 1-1 by bending, can plastic feet 1 and panel beating shell spare 2 be fixed in one tightly, has guaranteed that situation about becoming flexible does not appear in plastic feet 1 and panel beating shell spare 2.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
