Description
Technical field
The utility model relates to the communication facilities technical field, relates in particular to a kind of SFP interface and stops up piece.
Background technology
At present; many optical transmission devices are for protection circuit and make things convenient for the later stage dilatation all to reserve unnecessary SFP (Small Form-factor Pluggables) interface in advance; the SFP interface that has in the actual engineering is often vacant need not; again for cost consideration; can not insert the SFP module in the vacant SFP interface, only with its uncovered placement.But for a long time the SFP interface is opened wide, circuit devcie is aging easily and pile up dust, can use the later stage to impact, and influences the overall aesthetics of equipment simultaneously.
Chinese patent 200720196255.5 discloses the hot-swappable dustproof module of a kind of little encapsulation, comprising: shell, golden finger; Described shell is identical with the shell of optical module; Described golden finger is fixing in the enclosure; Closely contact with the metal spring leaf of optical module slot when the contact pin end of golden finger is used for inserting, the other end is vacant, is not electrically connected.Though this module can be used to prevent that dust from entering in the socket, complex structure, manufacturing cost is high.
Summary of the invention
The utility model discloses a kind of SFP interface simple in structure, cheap for manufacturing cost and stop up piece.
A kind of SFP interface stops up piece, comprise the obstruction block body, described obstruction block body comprises interconnective card-tight part and mouth-sealed portion, the card-tight part outer wall is provided with the plurality of elastic raised line, and mouth-sealed portion both sides sidewall is the perpendicular that is parallel to each other, and the distance between them is identical with the width of SFP interface, when stopping up piece insertion SFP interface, elasticity raised line and SFP interface inwall chucking, the end face of mouth-sealed portion is higher than the socket upper edge of SFP interface, and the bottom surface of mouth-sealed portion is lower than the socket lower edge of SFP interface.
Preferably, the end that described card-tight part deviates from mouth-sealed portion is connected with guide part, is convenient to stop up piece and inserts the SFP interface; More preferably, an end of described card-tight part connection guide part radially shrinks gradually and forms frustoconical sheets.
Preferably, the end that described mouth-sealed portion deviates from card-tight part is connected with pinch hand, is convenient to stop up piece and takes out from the SFP interface; More preferably, described pinch hand outer wall is provided with skid-proof regions, and when preventing to take out 8 obstruction pieces, finger skids.
Preferably, described elasticity raised line is distributed on the sidewall of card-tight part both sides.
Preferably, described card-tight part end face and bottom surface all have groove, and the card-tight part of groove both sides is provided with the plurality of elastic salient point, when stopping up piece insertion SFP interface, and elasticity salient point and SFP interface inwall chucking.
Be provided with the projection that matches with triangular groove on the SFP interface inwall in the described groove, be convenient to stop up the piece location.
The utility model stops up piece and do not comprise parts such as golden finger and shell, and is simple in structure, cheap for manufacturing cost, and by the socket sealing of mouth-sealed portion with the SFP interface, by card-tight part and SFP interface close-fitting, it is loosening to use the back to be difficult for, and good sealing effect, can play dustproof well, moisture-proof role.

Embodiment
As shown in the figure, a kind of SFP interface stops up piece, comprises the obstruction block body, stops up block body and is made by resilient material, as rubber etc.Stop up block body and be made up of interconnective card-tight part 3 and mouth-sealed portion 2, insert and take out for the ease of stopping up, an end that deviates from mouth-sealed portion 2 at card-tight part 3 connects guide part 4, and the end that mouth-sealed portion 2 deviates from card-tight part 3 connects pinch hand 1.For the ease of making and moulding, pinch hand 1, mouth-sealed portion 2, card-tight part 3 and guide part 4 join together, and various piece also can adopt other connected mode, as engagement connection etc.
Card-tight part 3 end faces and bottom surface are provided with groove 31, be provided with the projection 32 that matches with triangular groove on the SFP interface inwall in the groove 31, the card-tight part 3 of groove 31 both sides respectively is provided with two elasticity salient points 33, card-tight part 3 both sides respectively are provided with a horizontally disposed elasticity raised line 34, when the obstruction piece stretches into the SFP interface, elasticity salient point 33 and elasticity raised line 34 and SFP interface inwall chucking.Certainly stop up piece elasticity salient point 33 or elasticity raised line 34 can only be set, if satisfy card-tight part 3 can with SFP interface inwall chucking both can, prevent that the accident of stopping up piece from deviating from.Insert the SFP interface for the ease of card-tight part 3 simultaneously, the end that card-tight part 3 is connected guide part 4 radially dwindles formation one frustoconical sheets gradually.Elasticity raised line 34 is arranged to the inclined-plane near an end of guide part 4.
Mouth-sealed portion 2 both sides sidewalls are perpendicular, and distance between the two is identical with the SFP interface width, and when the obstruction piece stretched into the SFP interface, mouth-sealed portion 2 end faces were higher than the socket upper edge of SFP interface, the bottom surface is lower than the socket lower edge of SFP interface, guarantees the socket complete closed of mouth-sealed portion 2 with the SFP interface.Mouth-sealed portion 2 both sides sidewalls are set to perpendicular, mainly be for when SFP interface platoon is adjacent, two adjacent SFP interfaces also can use the obstruction piece of present embodiment, because when distance was greater than the SFP interface width between the mouth-sealed portion 2 both sides sidewalls, just can not use the obstruction piece simultaneously.
In order to prevent that taking out the obstruction piece from the SFP interface skids, be provided with skid-proof regions at pinch hand 1 outer wall, anti-slip tank 11 has been offered in the end face of pinch hand 1 and bottom surface in the present embodiment.
Use above-mentioned obstruction piece to stop up vacant SFP interface, guide part 4 and card-tight part 3 stretch into SFP interface inside, mouth-sealed portion 2 and pinch hand 1 are exposed at SFP interface outside, elasticity salient point 33 and elasticity raised line 34 and SFP interface inwall chucking, the socket of mouth-sealed portion 2 sealing SFP interfaces, when need taking out, only need pinch pinch hand 1, will stop up piece and from the SFP interface, extract and get final product.
