Description
Technical field
The invention belongs to optical connector technical field, particularly a kind of optical connector plug of mispluging of preventing by identifying information.
Background technology
Optical connector is for transmitting optical signal, to realize 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 fixed light connector plug and realize the light connection between optical connector plug.Conventional standard light connector 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 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 wrong plug position when wiring, once misplug, it will be very difficult detecting, thereby increase the difficulty of wiring work.
Chinese invention 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, in these two kinds of assemblies, on the optical connector plug of correspondence, be all provided with printed board, plug information storage chip is installed in printed board, on the pin of chip, be powered with metallic conduction part, 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 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 observe the light and shade situation of 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 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 to be all arranged on plug body and (at this, fore-end that plug of stationary housing and printed board is not installed to be called to plug body, so that distinguish with finished product plug by the corresponding stationary housing being set in outside plug body; Printed board and plug information storage chip and metallic conduction part on it are called to plug information module), concrete structure is: a side at stationary housing is provided with opening draw-in groove, two notch places of opening draw-in groove are provided with interior receipts card edge, plug information module packs in opening draw-in groove by the mode of strong dress, 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 being again 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.
Summary of the invention
The object of this invention is to provide a kind of optical connector plug with plug identifying information function, 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 present invention adopts following technical scheme: a kind of optical connector plug, comprise plug body and be connected to the plug information module on plug body side, at the rear portion of plug information module, be provided with the gland being fitted on plug body, plug information module is pressed on plug body and is realized 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 coordinating with the respective side of described printed board 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.
On the cylinder of described pin, along pin, be circumferentially interval with vertical convex tendon, 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 present invention adopts gland to compress is connected to plug information module on plug body, between gland and plug body, also adopt and press-fit the mode being connected, whole assembling process is simple, easy operating, convenient and swift, efficiency of assembling is high, and meanwhile, its maintenanceability is good, when breaking down, only need slightly exert oneself gland to take away, plug information module be separated with plug body, retracts very convenient.
The present invention offers after groove on plug body, plug information module can be sunk and is contained in this groove, is convenient to the location of plug information module, meanwhile, can correspondingly reduce the overall dimensions of plug.Projection in 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.On pin, arrange after convex tendon, pin is contacted with jack by convex tendon when with gland inserting, distortion after convex tendon is squeezed, and crushed element, to the recess distortion on pin surface, causes gland jack cracking while avoiding assembling due to wringing fit.When the plug information storage chip on 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.
