Abstract
The invention provides a SFP optical module unlocking apparatus comprising a port connected with at least one fiber connector. An elastic cantilever beam is disposed on the top of the port and comprises a fixed end, a movable end, and a locking end between the fixed end and the movable end. The locking end may synchronously move up and down along with the movable end. Since the SFP optical module unlocking apparatus employs an integrally-formed member and the elastic cantilever beam thereof and the locking end clinging to the cantilever beam may synchronously move up and down along with the movable end of the cantilever beam, when no external force is applied to the movable end and the movable end is in an initial state, if the SFP optical module unlocking apparatus is inserted into a cage, the locking end is locked by a lock hole of the cage in order that a SFP optical module is locked and in an operable state. When the movable end is pressed down, the locking end downwardly exits from lock hole of the cage such that the SFP optical module is unlocked and can be outwardly pulled out. Therefore, hot plug of the SFP optical module is achieved.
Description
Technical field
The present invention relates to a kind of SFP (Small Form Factor Pluggabe is called for short SFP) the miniaturization integrated module of optical transceiver (hereinafter referred to as SFP optical module), particularly relate 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, rely on lockhole set on the tapered end of module top and cage locking plate to interlock to add locking, module is fixed in cage work, when module needs outwards to extract, tapered end must exit the unblock 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, one take-up housing 4 and upper surface thereof arrange for multiple parts such as the tapered ends 5 that matches with optical module cage (Cage) lockhole, during assembling, first spring 3 is fixed on after bottom slide block 2 and inserts slide block base 4, again draw ring 1 is installed on take-up housing 4 rear end, under original state after this structure tripper is combined with SFP optical module, after whole module inserts cage, tapered end 5 is fixed by the cage hole of cage, module can normally work, when optical module is outwards extracted by needs in cage, rotate draw ring 1 to level and outwards drag, the unblock of whole optical module can be realized, this tripper structural member is many, assembling is difficult, whole SFP optical module cost is caused to increase.
Summary of the invention
The invention provides the SFP optical module tripper that a kind of structure is simple, cost is low.
For realizing above goal of the invention, the invention provides a kind of SFP optical module tripper, comprise Single port and connect at least one joints of optical fibre, described port top is provided with an elastic cantilever, the tapered end that this semi-girder comprises a stiff end, a movable end and is positioned between the two, this tapered end synchronously can 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.
Due to the SFP optical module tripper of said structure, have employed integrated molding part and elastic cantilever, the tapered end be attached on this semi-girder synchronously can move up and down with the movable end of semi-girder, when movable end is in original state without external force, 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, thus makes SFP optical module realize unblock outwards can to extract, realize the hot plug of SFP optical module.

embodiment explanation
Preferred embodiment is described in detail below in conjunction with accompanying drawing.
SFP optical module tripper 10 as shown in Figure 3, comprise Single port 11 and connect at least one joints of optical fibre, described port one 1 top is provided with an elastic cantilever 12, the tapered end 1203 that this semi-girder comprises stiff end 1201, movable end 1202 and is positioned between the two, this tapered end synchronously can 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, also can be 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, in base, light transmitting-receiving subassembly and pcb board are installed, just can form SFP optical module as shown in Figure 4, structure is simple, and cost is low.As shown in Figure 5, the tapered end 1203 be attached on this semi-girder 12 synchronously can move up and down with the movable end 1202 of semi-girder, when movable end 1202 is in original state without external force, 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 tapered end 1203 exits in self-locking hole 20 downwards, thus realizes SFP optical module and unlock in cage and can outwards extract, and realizes the warm connection function of SFP optical module.
