Description

SC type single fiber bi-directional SFP light transmitting-receiving-phantom piece

Technical field

The utility model relates to the integrated module of optical transceiver that kind of a kind of Optical Fiber Transmission is used, and relates in particular to a kind of SC type single fiber bi-directional SFP SFP (Small Form Pluggable) integrated module of optical transceiver.

Background technology

The single fiber bi-directional SFP SFP integrated module of optical transceiver, be widely used in FTTx optical access network transmission system, as Chinese utility model patent, the patent No. is: 200420102986.5, disclosing a kind of interface is the SC type single fiber bi-directional SFP integrated module of optical transceiver, as shown in Figure 1, comprise a module bodies 1, separate lock release 2, according to the requirement of SFP MSA multi-source agreement, after module bodies 1 is inserted the frame cage by the combination of separating lock release 2 and cage locking plate bayonet socket with separate the hot plug that realizes the SFP integrated module of optical transceiver.Establish a single fiber bi-directional assembly and a pcb board in the module bodies 1, separate lock release 2 and comprise that a base 21, has slide block 22, a spring 23, a top cover 24 and a draw ring 25 of wedge shape terminal 2201.Separate lock release 2 and flexibly connected by bolt by its base 21 and module bodies 1, the front end of this base 21 is provided with the buckle 2103 of projection, and this buckle and locking plate bayonet socket are adaptive; Slide block 22 is offered wedge shape terminal 2201 along base 21 chute inserts; The center 2301 of spring 23 is on the reference column 2202 of knot in shoe surface, two end supports is in the groove 2101 of base 21 both sides, the cross bar 2501 of draw ring 25 embeds in the set groove 2102 of base 21 edges, cover top cover 24 again, the pin 2401 of top cover 24 inserts in the groove 2102 so that fixed transverse rod 2501.The central authorities of cross bar 2501 are provided with a striking gear 2502, when upwards rotating draw ring 25, the afterbody 2203 that striking gear 2502 is stirred slide block 22 makes slide block move forward along chute, wedge shape terminal 2201 upwards backs down cage locking plate bayonet socket, module just breaks away from cage, thereby realizes the hot plug of the SFP integrated module of optical transceiver.Spring 23 is used to make slide block 22 to reset as the time spent in no external force, waits for the stirring of striking gear 2502 of draw ring 25.Because the afterbody of aforementioned base 21 need be offered darker groove with fixed pull ring 25, and the structure of draw ring 25 is also complicated, cost of manufacture is higher relatively, so just causes the length of the whole SFP integrated module of optical transceiver and highly all bigger than normal, is easy to generate interference when installing on frame.

Summary of the invention

For overcoming above shortcoming, the utility model provides a kind of overall dimensions little, simple in structure, and cost is low, the SC type single fiber bi-directional SFP SFP integrated module of optical transceiver easy for installation.

A kind of SC type single fiber bi-directional SFP SFP integrated module of optical transceiver that the utility model provides comprises module bodies reconciliation lock release, and module bodies is provided with a single fiber bi-directional assembly in it, and tail end is provided with the installing and locating card of separating lock release; Separate lock release, comprise a base, a slide block, a spring, a top cover and a draw ring; Draw ring is provided with rotating shaft and handle, and the center of rotating shaft is provided with a projection; The tail end of base is provided with and the suitable draw-in groove of the locator card of module bodies, base behind the location and module bodies flexibly connect, base upper surface is provided with and is used for the chute that slide slide block work front and back, the chute dead ahead is provided with buckle, and the chute both sides are provided with the shallow trench of storing rotating shaft and the pit at support spring two ends; The front end of slide block is provided with the wedge shape terminal, and the centre is provided with the cavity of putting spring, and the cavity center is provided with reference column, and the center of spring is around tying on this reference column; The lower end of top cover is provided with the relative commentaries on classics hole that forms rotating shaft of groove of groove and base, and draw ring is freely rotated, and top cover and base flexibly connect.

Because above-mentioned draw ring is simple in structure, fabrication and installation are convenient.And the rotating shaft of draw ring mainly is that the hole that forms after being combined with base by the groove that top cover is provided with is fixed, thereby has reduced the length and the height of whole module effectively, can not produce interference after optical module is installed on the system chassis.

Embodiment

Describe the utility model most preferred embodiment in detail below in conjunction with accompanying drawing.

By shown in Figure 2, the SC type single fiber bi-directional SFP SFP integrated module of optical transceiver inserts in the cage 300, and cage 300 is provided with locking plate bayonet socket 301, and the SFP integrated module of optical transceiver comprises: module bodies 100 is conciliate lock release 200.Module bodies 100 as shown in Figure 3 is provided with a single fiber bi-directional assembly 102 in it, tail end is provided with the installing and locating card 101 of separating lock release 200.As shown in Figure 4 and Figure 5 separate lock release 200, comprise a base 201, a slide block 202, a spring 203, a top cover 204 and a draw ring 205.Draw ring 205 as shown in Figure 6 is provided with rotating shaft 2051 and handle 2053, and the center of rotating shaft 2051 is provided with a projection 2052.The tail end of base 201 is provided with the draw-in groove 2011 suitable with locator card 101, and the base 201 behind the location and module bodies 100 are connected by bolt; Base 201 upper surfaces are provided with and are used for the chute 2013 that slide slide block 202 work front and back, and the dead ahead of chute is provided with buckle 2012, and the chute both sides are provided with shallow trench 2014 and the pit 2015 of putting draw ring rotating shaft 2051.The front end of slide block 202 is provided with wedge shape terminal 2021, and the centre is provided with the cavity 2024 of putting spring 203, and the cavity center is provided with reference column 2022, and on this reference column, two end supports is in pit 2015 around knot at the center of spring 203.The lower end of top cover 204 is provided with the commentaries on classics holes of the groove 2014 relative formation draw ring rotating shafts 2051 of groove 2041 and base 201, and draw ring 205 is freely rotated.Top cover 204 passes through bolt with base 201.

It is as follows that action is carried out in the hot plug of the SC type single fiber bi-directional SFP SFP integrated module of optical transceiver of the present utility model: after with the cage on the overall optical module insertion system frame, slide block 202 is because the effect of spring 203 is in reset mode, buckle 2012 is in the locking plate bayonet socket 301 of cage 300, and this moment, module was locked in operate as normal in the cage 300.When needs are done the heat dial-out with module, only need the handle 2053 of hand-held draw ring 205 outwards to rotate, the projection 2052 that is positioned at rotating shaft 2051 centers will promote slide block 202 forward, make the upwards locking plate bayonet socket 301 of jack-up cage 300 of its wedge shape terminal 2021, buckle 2012 separates with locking plate bayonet socket 301, module has broken away from cage 300 constraints, thereby reaches the hot plug of module.
