Abstract
The present invention relates to a dustproof mechanism of a socket, comprising a dustproof plate used for being movably assembled on a corresponding socket housing along a vertical direction, a reset elastic component used for applying an upward acting force to the dustproof plate, and a covering elastic component which is used for applying a downward acting force to the dustproof plate and is separated from the dustproof plate due to the acting force of a push plate of a plug when the plug is plugged in the socket, wherein the acting force applied to the dustproof plate from the covering elastic component is greater than the acting force applied to the dustproof plate from the reset elastic component so that the dustproof plate is located at a position where the socket housing is covered. The dustproof mechanism of the present invention solves the problem that a plug has a large length dimension due to turnover movement of the dustproof plate in the prior art.
Description
Technical field
The present invention relates to the dust-proof mechanism of socket.
Background technology
In the rack of communication equipment, need to carry out data communication between backboard and daughter board, at present, use comparatively ripe communication mode to be adopt the transmission of high-speed-differential electric connector, this communication mode, due to the defect of electric signal transmission, has certain transmission limit.
And if the data communication between backboard and daughter board adopts Optical Fiber Transmission, in transmission capacity, the more existing electrical transmission of meeting is much higher, but the fiber junctions that Optical Fiber Transmission relates between daughter board with backboard is connected, because fiber core external diameter is in a μm level, in addition the characteristic of trimmed book body, the quality of docking contact end face is extremely responsive.In actual use, back panel connector is installed in rack in advance with backboard usually, daughter board is installed as required follow-up, because machine room is generally between non-clean area, easily introduce the booties such as dust on cabinet female connector, then easily cause end surface of optical fiber connector booty, and when product uses, normally air cooling way in cabinet, even if plug and socket are to after inserting, still has the necessity of carrying out dustproof design.
The existing this optical connector " backboard optical connector " disclosed in Chinese patent CN104412141A being provided with dustproof construction, a kind of plug and socket is disclosed in this patent document, the Socket casing of optical fiber contact pins parts is provided with in socket comprises, the front end of Socket casing is hinged with the dust excluding plate that hinge axes extends in left-right direction, plug comprises the plug casing with push pedal, at plug, during socket grafting, push pedal pushing tow the front face of dust excluding plate and dust excluding plate is rotated clockwise and digs, thus make the optical fiber contact pins in plug casing and the optical fiber contact pins in socket to inserting, at plug, after socket grafting terminates, make plug, socket is separated, dust excluding plate turns under relying on deadweight counterclockwise and capping Socket casing again, thus the optical fiber contact pins in guarantee Socket casing is in dustfree environment.Existing this dustproof construction Problems existing is: at plug, after socket is separated, dust excluding plate relies on and to turn under gravity and capping Socket casing again, only rely on the dust excluding plate of gravitational orientation easily to produce to rock and and produce gap between Socket casing, dust may pollute optical fiber contact pins through this gap, certain what is more important, because the socket of complete capping Socket casing wanted by dust excluding plate, therefore the above-below direction length of dust excluding plate is general longer, dust excluding plate relies on upset realize capping Socket casing and get out of the way plug, the flip-flop movement amplitude of dust excluding plate is larger, in order to dodge dust excluding plate, longer with regard to what need the push pedal of plug to do, finally cause the length dimension of plug larger.
Summary of the invention
The object of the present invention is to provide a kind of dust-proof mechanism of socket, cause the larger-size problem of plug length to solve in prior art because of dust excluding plate flip-flop movement.
In order to solve the problem, technical scheme of the present invention is:
A kind of dust-proof mechanism of socket, comprise and be assemblied in the dust excluding plate on respective socket housing for guiding movement along the vertical direction, also comprise return springs for applying upward direction active force to described dust excluding plate and for applying in downward direction active force to described dust excluding plate and in plug insertion socket process because of the push pedal active force of plug and the capping elastic component that departs from of dust excluding plate, the active force of capping elastic component to dust excluding plate is greater than return springs makes dust excluding plate be in the position of capping Socket casing to the active force of dust excluding plate.
Described capping elastic component is that upper end is arranged at described Socket casing upper and lower end and is pressed in compression shell fragment on described dust excluding plate.
Socket casing is provided with the power transmission cam departed from dust excluding plate because of push pedal active force to realize capping elastic component for power transmission between described push pedal and compression shell fragment, the rotation of power transmission cam is assemblied on the described Socket casing on the downside of compression shell fragment, the pivot center of power transmission cam extends in left-right direction, power transmission cam is provided with for by the forced section of described push pedal pushing tow and the force section for compressing shell fragment described in pushing tow.
Compression shell fragment and power transmission cam are all arranged at the middle part on Socket casing left and right directions, and what push pedal dust excluding plate is provided with on the described plug of confession was passed through along the longitudinal direction wears groove.
Described return springs is the back-moving spring that axis extends along the vertical direction.
Described dust excluding plate comprises horizontally disposed top plate portion and is arranged at least one riser portion of top plate portion front end, capping elastic component, return springs act on the both sides up and down of top plate portion respectively, form the indent step of the contact pin components front end for being installed in socket between top plate portion and riser portion.
Riser portion has two, and two riser portion time intervals are arranged.
Beneficial effect of the present invention is: when this socket is not with plug grafting, active force due to capping elastic component is greater than the active force of return springs, therefore the position being in capping Socket casing that dust excluding plate is firm, be that plug is to time slotting, the push pedal on plug to capping elastic component transmitting forces, by the active force of push pedal, capping elastic component and dust excluding plate depart from, by the active force of return springs, dust excluding plate moves and gets out of the way plug, plug, socket can grafting smoothly.Dust excluding plate in the present invention realizes capping Socket casing and get out of the way plug by moving up and down, and does not substantially have motion amplitude in the longitudinal direction, and the push pedal therefore on plug is not required to be dodges dust excluding plate and extension length, can reduce the entire length of plug.
