Description
Technical field
The utility model belongs to the optical connector technical field, particularly a kind of optical connector plug mispluged that prevents by identifying information.
Background technology
Optical connector is to realize for transmitting optical signal the device that light connects in optical communication, and optical connector consists of optical connector plug and optical connector adapter, and optical connector adapter is for the fixed light connector plug and realize that the light between optical connector plug connects.Standard light connector commonly used has two types of LC and SC, and corresponding optical connector plug has LC and two kinds of plugs of SC.
At present, optical communication base stations etc. are for the place of transmitting optical signal, on optical communication equipment, be plugged with a large amount of LC and or the SC optical connector plug, these plugs have the light signal of different information for transmission bearer, and because these LC or SC plug are standard plug, its profile is the same, so be very easy to the wrong plug position when wiring, once misplug, it will be very difficult detecting, thereby increase the difficulty of wiring work.
Chinese utility model patent application 201010298386.0 discloses a kind of LC optical connector assembly with anti-mis-insertion indication, a kind of SC optical connector assembly with anti-mis-insertion indication is also disclosed simultaneously, all be provided with printed board on the optical connector plug of correspondence in these two kinds of assemblies, the plug information storage chip is installed in printed board, be powered with the metallic conduction part on the pin of chip, when plug inserts corresponding optical connector adapter, what the information exchange of storage was crossed metallic conduction part and metallic elastic part on adapter in chip contacts the connecting system mainboard, when information is coincide, system board sends instruction, the pilot lamp that correspondence is arranged on adapter is bright, otherwise, pilot lamp does not work, by the light and shade situation of observing pilot lamp on adapter judge wiring to mistake, thereby prevent that plug from mispluging.Canned data can be the signal of unique identification plug identity in chip, as the plug numbering, can be also that other can identify plug for information about, such as, the signal that plug transmits, optical cable model of connecting etc.
Two kinds of optical connector plugs in above-mentioned patented claim, its plug information module is all to be arranged on by the corresponding outer stationary housing of plug body that is set in that on plug body, (fore-end that the plug of stationary housing and printed board will be installed at this is called plug body, so that distinguish with the finished product plug; Printed board and plug information storage chip and metallic conduction part on it are called to the plug information module), concrete structure is: the side at stationary housing is provided with the opening draw-in groove, two notch places of opening draw-in groove are provided with interior receipts card edge, the plug information module is packed into by the mode of strong dress in the opening draw-in groove, spacing along carrying out backstop by interior receipts card.This mounting means of plug information module, when module breaks down or need to again write plug storage information, dismounting is more difficult, even and easily cause the damage of module or stationary housing to damage; Moreover, stationary housing is sleeved on outside plug body, the structure that belongs to three encloseds, its structure internally to meet can with being connected of plug body, externally to meet when plug inserts adapter set casing physical efficiency cooperation corresponding to adapter and not affect again being connected of plug and adapter, make the complicated structure of stationary housing, also caused the physical dimension of plug and adapter to increase, be unfavorable for the miniaturization development of device.
The utility model content
The purpose of this utility model is to provide a kind of optical connector plug with plug identifying information function, and the operation of the plug information module of this plug when mounting and dismounting with plug body is more convenient.
For achieving the above object, the utility model adopts following technical scheme: optical connector plug, comprise plug body and be connected to the plug information module on the plug body side, be provided with the gland be fitted on plug body at the rear portion of plug information module, the plug information module is pressed on plug body and realizes and being connected of plug body by described gland.
Described plug body is provided with the groove with the printed board adaptation of plug information module, and described plug information module is heavy to be contained in this groove.
Plug information storage chip on described plug information module is arranged on the plate face that deviates from plug body of described printed board, and described gland is provided with for holding the storehouse that holds of described plug information storage chip.
The sidewall of described groove is provided with for the respective side of described printed board, coordinating the projection that holds out against printed board.
Described gland is fitted on plug body by being located at respectively jack on gland and plug body and the wringing fit of pin.
Circumferentially be interval with vertical convex tendon along pin on the cylinder of described pin, pin is realized the wringing fit with jack by convex tendon.
Described pin is located on plug body, and described jack is located on gland.
The mode that the utility model adopts gland to compress is connected to the plug information module on plug body, also adopt and press-fit the mode be connected between gland and plug body, whole assembling process is simple, easy operating, convenient and swift, efficiency of assembling is high, and simultaneously, its maintenanceability is good, when breaking down, only need slightly exert oneself gland is taken away, the plug information module separates with plug body, retracts very convenient.
After the utility model is offered groove on plug body, the plug information module can be sunk and is contained in this groove, be convenient to the location of plug information module, simultaneously, can correspondingly reduce the overall dimensions of plug.Projection on recess sidewall can tightly be pushed up printed board and be pressed on relative sidewall when assembling, plays the effect of fixed printed board, makes assembling more solid and reliable.After on pin, convex tendon being set, pin is contacted with jack by convex tendon with the gland inserting time, the convex tendon rear distortion that is squeezed, and crushed element, to the recess distortion on pin surface, causes the gland jack to ftracture while avoiding assemble due to wringing fit.When the plug information storage chip on the plug information module is located on the plate face outwardly of printed board; on gland hold storehouse can be by this chip buckle closure holding in storehouse at gland; chip is played a protective role; also make mounting structure more reasonable, simple, be convenient to the fixing of plug information module simultaneously.
