Please refer to Fig. 3 to shown in Figure 7, described protection mechanism 4 comprise elastic component 41 and cooperate with elastic component 41 cover 42.Described elastic component 41 comprises that first, second curled portion 411,412 that is positioned at both sides, first, second pressure section 413,414 that extends forward from first, second curled portion 411,412 1 ends reach the extension 415 that extends back from first, second curled portion 411,412 other ends.Described extension 415 be roughly " U " shape and in order to cover door and 42 compress mutually.Described first pressure section 413 comprises first horizontal part 4131 that extends forward from first volume pars convoluta 411, from first horizontal part 4131, first vertical portion 4132 and forward and first rake 4133 of downward-sloping extension of vertical bending upwards from first vertical portion 4132.The structure of the structure of described second pressure section 414 and first pressure section 413 is identical, and then elastic component 41 is symmetrical arranged.Described second pressure section 414 comprises second horizontal part 4141 that extends forward from second curled portion 412, from second horizontal part 4141, second vertical portion 4142 and forward and second rake 4143 of downward-sloping extension of vertical bending upwards from second vertical portion 4142.Described first, second rake 4133,4143 is positioned at sustained height and all protrudes into receiving space 7, is convenient to first, second rake 4133,4143 and simultaneously the function that supports and guide is played in the insertion of butt connector.Described extension 415 comprises the blocking part 4151 of vertical butt joint connector direction of insertion and horizontal expansion.Described elastic component 41 also is provided with first, second limiting section 416,417 that turns round bending respectively from the front end of first, second rake 4133,4143 backward.Described first, second limiting section 416,417 is parallel to the below that first, second horizontal part 4131,4141 and first, second limiting section 416,417 correspondences are positioned at first, second horizontal part 4131,4141.Described first, second limiting section 416,417 extends outside the receiving space 7 and is contained in first, second groove 103,104 to compress mutually with insulating body 1.The described door 42 that covers comprises shielding portion 421 and is positioned at a pair of first, second erection columns 422,423 of shielding portion 421 bottoms.
During assembling, first, second curled portion 411,412 of described elastic component 41 is socketed on first, second erection column 422,423, and then integral body is accommodated in the insulating body 1.Wherein, first, second curled portion 411,412 and first, second erection column 422,423 are contained in the mounting groove 105, and fore-and-aft direction can not move.Described first, second curled portion 411,412 left and right directions are mounted insulating body 1 restriction at groove 105 two ends, equally can not left and right sides play.Simultaneously, first, second limiting section 416,417 is contained in first, second groove 103,104 and compress mutually with insulating body 1, to guarantee that blocking part 4151 is resisted against on the front surface 4211 of shielding portion 421, and then make shielding portion 421 can be maintained at vertical position, and then can prevent that other foreign matters from damaging light receiving element 34 and dust and other impurities is polluted light receiving element 34 with shield light receiving element 34.
Described metal shielding casing 5 comprises around hyoplastron 11 roof 51, diapire 52 and two side 53,54 on every side.Described diapire 52 is provided with the recess 521 that is arranged with from end face thereafter.Described roof 51, diapire 52 and two side 53,54 are equipped with and extend in the receiving space 7 and the shell fragment 55 in order to compress mutually with butt connector, hold butt connector and grounding function to reach button.
Please join Fig. 4 and shown in Figure 5, when butt connector when first, second rake 4133,4143 inserts in the receiving space 7 after by forward direction, described first, second rake 4133,4143 is compressed by butt connector and elastic deformation takes place downwards, and then drive 4132,4142 distortion of first, second vertical portion, and first, second rake 4133,4143 and first, second vertical portion 4132,4142 are extended outside the receiving space 7 and be contained in the host cavity 106.Simultaneously, described first, second erection column 422,423 is contained in the host cavity 106 by first, second curled portion 411,412 drag down.Finally make shielding portion 421 break away from receiving space 7, therefore, in the insertion process of butt connector, can not play any barrier effect, and then can not influence the use of butt connector.Because described host cavity 106 runs through the high portion 12 of frame downwards, and then can provide elastic component 41 enough deformation spaces, in addition, also be convenient to reduce the height of the utility model opto-electric connector 100.
Certainly, in other embodiments, described protection mechanism 4 can not be provided with elastic component 41, and at this moment, the described door 42 that covers can directly be suspended on the roof 51 of metal shielding casing 5.Under free state, the described door that covers 42 is in vertical position, and then can shield light receiving element 34; When butt connector inserts receiving space 7, described covering on door 42 is resisted against metal shielding casing 5 by jack-up the inside surface of roof 51, and then can not influence the use of butt connector; Certainly, if receiving space 7 is not high enough, described roof 51 can be provided with from its inside surface punching press and can accommodate the depression of covering door 42, to realize not influencing the purpose that butt connector uses.
In sum, it below only is preferred embodiment of the present utility model, should not limit scope of the present utility model with this, be that every simple equivalent of being done according to the utility model claims and utility model description changes and modifies, all should still belong in the scope that the utility model patent contains.
