Abstract

The utility model provides an SFP optical module unlocking device comprising a port which is connected with at least one fiber connector. The top of the port is provided with an elastic cantilever beam. The cantilever beam comprises a fixed end, a movable end and a lock head arranged between the fixed end and the movable end, wherein the lock head can follow the movable end to synchronously move up and down. The integratedly-moulded piece and the elastic cantilever beam are utilized, so that the lock head attached to the cantilever beam can follow the movable end of the cantilever beam to synchronously move up and down; when the movable end has no external force and is in original state, if the SFP optical module unlocking device is inserted into a cage, the lock head is locked by a lock hole of the cage, and thus the SFP optical module is locked in a workable state; and when the movable end is presses down, the lock head is retreated downwards from the lock hole of the cage, and thus the SFP optical module is unlocked and can be pulled out outwards, and hot plugging of the SFP optical module is realized.

Description

A kind of SFP optical module tripper

Technical field

The utility model relates to a kind of SFP (Small Form Factor Pluggabe is called for short SFP) miniaturization integrated module of optical transceiver (hereinafter to be referred as SFP optical module), relates in particular to SFP optical module tripper.

Background technology

According to the regulation of miniaturization integrated module of optical transceiver MSA SFP multi-source agreement, when SFP optical module inserts the cage in frame, to rely on lockhole set on the tapered end at module top and cage locking plate to interlock to add locking, module is fixed in cage works, when module need to outwards be extracted, tapered end must exit the release that can realize module in self-locking hole, and now module is outwards extracted, and finally completes the warm connection function of SFP optical module.SFP optical module tripper as depicted in figs. 1 and 2, comprise: a draw ring 1, one slide block 2, one spring 3, a plurality of parts such as tapered end 5 for matching with optical module cage (Cage) lockhole that one take-up housing 4 and upper surface thereof arrange, during assembling, after first spring 3 being fixed on to slide block 2 bottoms, insert slide block base 4, again draw ring 1 is installed on to take-up housing 4 rear ends, under original state after this structure tripper is combined with SFP optical module, whole module is inserted after cage, tapered end 5 is fixed by the cage hole of cage, module can work, when needs are outwards extracted optical module in cage, rotate draw ring 1 to level and outwards drag, can realize the release of whole optical module, this tripper structural member is many, assembling is difficult, cause whole SFP optical module cost to increase.

Utility model content

The utility model provides a kind of simple in structure, SFP optical module tripper that cost is low.

For realizing above goal of the invention, the invention provides a kind of SFP optical module tripper, comprise that a port is connected to few joints of optical fibre, described port top is provided with an elastic cantilever, this semi-girder comprises a stiff end, a movable end and is positioned at a tapered end between the two, and this tapered end can synchronously move up and down with movable end.

The integrated profiled member of described SFP optical module tripper.

Described port connects joints of optical fibre.

Described port connects two joints of optical fibre.

SFP optical module tripper due to said structure, integrated molding part and elastic cantilever have been adopted, the tapered end being attached on this semi-girder can synchronously move up and down with the movable end of semi-girder, when movable end is without external force during in original state, if this SFP optical module tripper inserts cage, tapered end will be pinned by the lockhole of cage, and SFP optical module is in the lock state.When movable end is pressed, now tapered end exits downwards in the lockhole of cage, thereby make SFP optical module realize release, can outwards extract, and realizes the hot plug of SFP optical module.

embodiment

Below in conjunction with accompanying drawing, describe most preferred embodiment of the present invention in detail.

SFP optical module tripper 10 as shown in Figure 3, comprise that a port 11 connects at least one joints of optical fibre, described port one 1 top is provided with an elastic cantilever 12, this semi-girder comprises a stiff end 1201, a movable end 1202 and is positioned at a tapered end 1203 between the two, and this tapered end can synchronously move up and down with movable end 1202.When port one 1 connects joints of optical fibre, now, SFP optical module is the single fiber bi-directional integrated module of optical transceiver; When port one 1 connects two joints of optical fibre, now, SFP optical module comprises a light emission component and an optical fiber receive module.Tripper 10 of the present invention can be injected into one-body molded, can be also integrated metalwork.

Tripper 10 in said structure, if the front end corresponding with port one 1 makes it form integrated SFP optical module base (Housing) to external expansion, light transmitting-receiving subassembly and pcb board are installed in base, just can form SFP optical module as shown in Figure 4, simple in structure, cost is low.As shown in Figure 5, the tapered end 1203 being attached on this semi-girder 12 can synchronously move up and down with the movable end 1202 of semi-girder, when movable end 1202 is without external force during in original state, if this tripper 10 inserts cage, tapered end 1203 is pinned by the lockhole 20 of cage, and SFP optical module is in the lock state.When movable end 1202 is pressed, now in the downward self-locking hole 20 of tapered end 1203, exit, thereby realize the release in cage of SFP optical module, can outwards extract, realize the warm connection function of SFP optical module.
