Abstract

The present invention relates to a drawing structure of an optical fiber transmitting / receiving module, which comprises a terminal socket and an optical fiber transmitting / receiving main body, wherein the optical fiber transmitting / receiving main body can be freely inserted and pulled in the socket; an elastic buckling chip is formed at the end edge of an insertion opening of the bottom of the socket; the surface of the main body is provided with a tenon which is used for clamping and buckling the elastic buckling chip of the socket. The present invention is characterized in that a blocking frame is formed at the back of the tenon on the main body; the blocking frame at the same side of the tenon is dented with a clamping groove which is used for embedding and combining an arch elastic chip; the front end edge of the chip body of the arch elastic chip, which is matched with the tenon, is provided with a fourchette-shaped notch groove, and the end of the chip body forms a bending chip which can be embedded and fixed in the clamping groove. Therefore, when the arch elastic chip is pressed in a plate state, the front end edge of the chip body can forwards extend and upwards warp, and therefore, the elastic buckling chip is higher than the tenon. The main body is easily drown and disengaged from the buckle of the socket.

Description

A kind of drawing-out structure of optical fiber transceiver module

Technical field

The invention relates to a kind of drawing-out structure of optical fiber transceiver module, be meant a kind of especially in order to grafting buckle that optical fiber transceiver main body and terminal socket are provided and the drawing-out structure design that breaks away from buckle.

Background technology

In the optical communication field, with 3M _TMThe miniature fiber transceiver module (SFP, SmallFrom-Factor Pluggable) of the leading development of company, but its optical fiber transceiver main body is to be designed to sleeve in a terminal socket, and for joints of optical fibre grafting combination; For reaching the convenience that system's cloth is built and keeped in repair, inter-module all possesses the cassette drawing-out structure usually, in order to substituting application.

For meeting aforementioned module standardization requirement, the cooperation exploitation of optical fiber transceiver agent technology must possess the condition that can produce the cassette extract function with the socket bottom surface in abutting connection with the set elastic fastening plate of socket edge; Any means known, be to form a tenon that can snap in the elastic fastening plate button hole, and establish a Carry bar plate, utilize the Carry rod principle in the tenon rear in optical fiber transceiver body surfaces, Carry bar plate is differed from be subjected to pressure side make progress lifting with the elastic fastening plate top from tenon, in order to the extraction of optical fiber transceiver main body; Above-mentioned known means have its basic implementation result admittedly, only, lose considering of competitive power based on avoiding domestic manufacturers to be subjected to the holding together to break restriction of foreign patent power, how to provide another kind to meet that structure is simplified, the drawing-out structure of benefit easy to implement, satisfy motivation and the emphasis place designed for the present invention.

Summary of the invention

The present invention aims to provide a kind of slotting structure of getting of optical fiber transceiver module, make optical fiber transceiver main body must have the buckle function grafting easily, extract in terminal socket.

For achieving the above object, the slotting means of getting execution that structure adopts of a kind of optical fiber transceiver of the present invention module, be that to comprise that a terminal socket and can freely be inserted the optical fiber transceiver main body of taking out in socket two partly main, this socket ora terminalis place, socket bottom surface is formed with an elastic fastening plate, this body surfaces has a tenon for socket elastic fastening plate buckle, and it is characterized in that: main body is prolonged the tenon rear and is formed with a retaining frame, this retaining frame is concaved with a draw-in groove and is embedded combination for an arch shrapnel in the tenon same side, this arch shrapnel is that tool forms by compressive strain and the plastics or the metal material one of replying the original shape ability, its lamellar body front-end edge cooperates tenon to offer a fourchette shape gap slot, and the lamellar body end has and can embed the bent sheet that is fixed in the draw-in groove; In view of the above, when arch shrapnel was pressed into the tabular attitude, the lamellar body front-end edge can stretch and upwarp action the elastic fastening plate holder is raise in tenon forward, makes main body be broken away from the extraction of socket buckle easily.

Embodiment

Modern for making your juror more deep understanding be arranged to the technical characterstic of this case invention, the special icon that cooperates is enumerated preferred embodiment, further describes as follows:

The slotting structure of getting of a kind of optical fiber transceiver of the present invention module as shown in Figure 1 to Figure 3, is to comprise a terminal socket 10, reaches one and can freely insert the optical fiber transceiver main body 20 2 main parts of taking out in socket, wherein:

This socket 10 is for possessing the metal shell of socket, and its bottom surface is formed with an elastic fastening plate 11 in adjacency socket edge place to offer the duct mode, and this elastic fastening plate front end has the folding face 12 of prying slightly upwards, and should run through a button hole 13 by the folding face;

In addition these main body 20 its shells are to become the metal shell that can be inserted in by the jack end contraposition of socket, this housing differs from the insertion end bottom surface and is provided with a tenon 21, be formed with a retaining frame 22 and prolong the tenon rear, this retaining frame is concaved with a draw-in groove 23 and is embedded combination for an arch shrapnel 24 in the tenon same side, this arch shrapnel is that tool forms by compressive strain and the plastics or the metal material one of replying the original shape ability, its lamellar body front-end edge cooperates tenon to offer a fourchette shape gap slot 241, and the lamellar body end is formed with and can correspondence embeds the bent sheet 242 that is fixed in draw-in groove;

Hold said structure, show, when pegging graft combination as Fig. 4,5, resist location by main body retaining frame 22, the elastic fastening plate 11 of socket can mat front ends folding faces 12 tilt angle, be close to main body 20 tenon 21 that makes that the bottom surface dislocation moves that joins and snap in button hole 13, and reach the effect of buckle; When desire extracts main body 20, as shown in Figure 6, only need bestow arch shrapnel 24 with finger tip and push, then arch shrapnel differs from bent sheet 242 ends can stretch and upwarp action forward along with equalizing of lamellar body holder and rises elastic fastening plate 11, makes main body 20 be broken away from the extraction easily of socket 10 buckles smoothly.

As the slotting structure of getting of above-mentioned a kind of optical fiber transceiver module, show that as Fig. 4 wherein this is incorporated into the arch shrapnel 24 of main body 20, high some position, its surface is formed with friction bar 25, in order to the action of exerting pressure of not slippage of finger tip; Show that for another Fig. 3 these main body 20 its draw-in groove 23 surfaces are further to be provided with a projection 26, and bent sheet 242 abutted surfaces of arch shrapnel also are formed with the groove 243 of a corresponding projection, make arch shrapnel 24 after combination have the fixed effect of non-return clip.

In sum, learn the slotting structure of getting of a kind of optical fiber transceiver module of the present invention, really can reach its expected effect, its structure is simplified and is easy to make assembling and certain implementation benefit that moves, known to the inventor, this invention technical characterstic does not also see the preceding publication of application, really belonging to another novel good wound of like product, files an application in the whence in accordance with the law, requests your office and gives and scrutinize, and grant accurate deserved right, for praying.
