Description
Technical field
Connector and connection the present invention relates to the connector shell in field of signal transmissions and using the connector shell
Device assembly.
Background technology
In the cabinet of communication equipment, need into row data communication between backboard and daughter board, at present, use is more mature
Communication mode be to be transmitted using high-speed-differential electric connector, the defects of this communication mode is due to electric signal transmission, has one
Fixed transmission limit.
And if the data between backboard and daughter board are communicated and transmitted using optical fiber, it can more existing electrical transmission in transmission capacity
High is more, but optical fiber transmission is related to the fiber junctions connection between daughter board and backboard, since fiber core outer diameter is in a μm grade, adds
Trimmed book body characteristic, the quality of docking contact end face is extremely sensitive.In actual use, back panel connector is usually pre- with backboard
It is first installed in cabinet, daughter board is installed as needed follow-up, since computer room is usually non-clean section, is readily incorporated dust etc.
On booty to cabinet female connector, end surface of optical fiber connector booty is then be easy to cause, and in product in use, being typically wind in cabinet
After cold mode, even plug and socket are to inserting, still there is the necessity for carrying out dustproof design.
The existing this optical connector for being provided with dustproof construction as disclosed in Chinese patent CN104412141A " use by backboard
Optical connector " discloses a kind of plug and socket in the patent document, and socket includes the interior Socket casing for being equipped with optical fiber contact pins,
The front end of Socket casing is hinged with the dust excluding plate that hinge axes extend in left-right direction, and plug includes the jack shell with push plate
Body, in plug, socket grafting, push plate pushing tow the front face of dust excluding plate and rotates clockwise dust excluding plate and dig, so as to
Make the optical fiber contact pins in the optical fiber contact pins and socket in plug casing to inserting, after plug, socket grafting, make plug, insert
Seat separation, dust excluding plate is by turning under dead weight counterclockwise and covering Socket casing again, so as to which the optical fiber ensured in Socket casing is inserted
Needle is in dustfree environment.Existing this dustproof construction has problems in that：The engagement process of push plate and dust excluding plate such as Fig. 1
It is shown：Push plate 1 with the pushing tow of dust excluding plate 2 during, F1, F2, F3 represent dust excluding plate in rotation process respectively, and push plate is to anti-
The thrust direction of dirt plate, as seen from the figure, in dust excluding plate rotation process, push plate exists always to the torque arm length of the thrust of dust excluding plate
It changes, when push plate is in vertical state, the arm of force is maximum, and with the rotation of dust excluding plate, the arm of force tapers into, that is to say, that
In order to realize that dust excluding plate rotates and required thrust is increasing, this aspect can increase the grafting difficulty of plug, socket, another
For aspect in plug, socket grafting later stage, operating personnel, which must apply larger thrust, could realize that dust excluding plate rotates, this is big
Thrust can increase the grafting speed of plug, and plug generates larger shock with socket could complete the grafting process of plug, socket, this
Sample can reduce the service life of plug；In addition, after dust excluding plate is dug completely, dust excluding plate cannot be hidden in push plate, can be increased in this way
The size of head is inserted, the miniaturization for being unfavorable for plug makes.
Invention content
The arm of force suffered by dust excluding plate will not change during can ensureing grafting the purpose of the present invention is to provide one kind
Connector shell；The present invention also aims to provide a kind of connector and connector assembly using the connector shell.
To solve the above-mentioned problems, the technical solution of connector shell is in the present invention：
Connector shell, including ontology, ontology front end is hinged with the dust excluding plate that pivot center extends in left-right direction, described
The load axis with the pivot center eccentric setting is provided on dust excluding plate, load axis has for by corresponding intermateable connector
Push plate on pushing tow inclined-plane pushing tow and arc-shaped load-carrying surface that the dust excluding plate is made to be overturn along clockwise direction around hinge axes.
The load axis, two load axis coaxial lines to be arranged in the left and right of dust excluding plate there are two settings on the dust excluding plate
Both ends.
Being used in the sealing ring of ontology sealing cooperation for annular is provided on the dust excluding plate.
It is equipped between the ontology and dust excluding plate towards the dust excluding plate and applies elastic acting force so that the dust excluding plate has
Rotate counterclockwise the elastic component of trend.
The elastic component is set on the ontology, is provided on the dust excluding plate and the corresponding triangle of the elastic component
Shape pushing tow protrusion, triangle pushing tow protrusion have the arched top pushing surface for the elastic component pushing tow.
The technical solution of connector is in the present invention：
Connector, including connector shell, connector shell includes ontology, and ontology front end is hinged with pivot center along left and right
The dust excluding plate of direction extension, the load axis with the pivot center eccentric setting is provided on the dust excluding plate, and load axis has
For being made the dust excluding plate around hinge axes along clockwise by the pushing tow inclined-plane pushing tow in the push plate on corresponding intermateable connector
The arc-shaped load-carrying surface of direction overturning.
The load axis, two load axis coaxial lines to be arranged in the left and right of dust excluding plate there are two settings on the dust excluding plate
Both ends are equipped between the ontology and dust excluding plate and apply elastic acting force towards the dust excluding plate so that the dust excluding plate has the inverse time
Needle rotates the elastic component of trend, and the elastic component is set on the ontology, is provided on the dust excluding plate and the elastic component
Corresponding triangle pushing tow protrusion, triangle pushing tow protrusion have the arched top pushing surface for the elastic component pushing tow.
The technical solution of connector assembly is in the present invention：
