Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Consult Fig. 2 and Fig. 3, be the preferred embodiment of the utility model fibre optic attenuator 2, comprise a linkage unit 3, and be located at the plant part 4 in this linkage unit 3, and the attenuation units 5 be located in this linkage unit 3.
This linkage unit 3 comprise a housing 6, by the pressure bullet portion of these housing 6 outside oblique extensions 31, by these housing 6 outside oblique extensions and the force section 33 that is connected with this pressure bullet portion 31; And two protruded out by these pressure bullet portion 31 both sides respectively and the projection 32 of adjacent this housing 6; This housing 6 have a socket piece 61, one by these socket piece 61 classes dwindle extend and with these socket piece 61 integrated plug spares 62; And two connecting holes 63 that are respectively formed at 62 liang of opposite location of this plug spare and adjacent this socket piece 61; This socket piece 61 and this plug spare 62 one common peripheral are around defining a passage 64; This passage 64 have the large aperture portions 641, in this socket piece 61 of being formed at be formed in this plug spare 62 and the aperture less than the small-bore portion 642 of this large aperture portion 641; And one connect this large aperture portion 641 and small-bore portion 642 shoulder 643, and this small-bore portion 642 have one be communicated with this large aperture portion 641 set section 644, one by this set section 644 towards opposite these large aperture portion 641 direction convergents against section 645, and one connect this against section 645 and aperture greater than this inserting section 646 against section 645; Because the relation at visual angle only shows a connecting hole 63 in the drawings.
Wherein the pressure bullet portion 31 of this linkage unit 3 be by this plug spare 62 towards the outside oblique extension of the direction of this socket piece 61, this force section 33 be by this socket piece 61 towards the oblique extension of this plug spare 62 directions, and have one be used to increase friction force uneven surface 331.In the present embodiment, the uneven surface 331 of this force section 33 is formed with several indentures that are provided with at interval, but not as limit, also can be with forming like modes such as several protruding grains or netted impressions.
This plant part 4 comprises that the body 41, in the passage 64 of being located at this linkage unit 3 is formed on this body 41 and the slotted eye 42 that is connected with this passage 64; And two protruded out and blocked the clamping block of establishing 43 mutually with the connecting hole 63 of this linkage unit 3 respectively by 41 liang of opposite location of this body; Because the relation at visual angle only shows a clamping block 43 in the drawings.
This attenuation units 5 is arranged in this passage 64; Comprise and be located in this set section 644 and an end is located at this and is stretched out and part protrudes out first contact pin 52 of this inserting section 646 by this Plug pin patch bay 51 against the Plug pin patch bay of section 645 51; And one by this Plug pin patch bay 51 in contrast to outward extending second contact pin 53 of the direction of this first contact pin 52, an attenuating fiber (figure do not show) is housed respectively in this first contact pin 52, second contact pin 53.
Consult Fig. 4; Be earlier this attenuation units 5 to be inserted this linkage unit 3 by the large aperture portion 641 of this linkage unit 3 towards the direction of this small-bore portion 642 in the assembling; Make an end of this Plug pin patch bay 51 replace this small-bore portion 642 against section 645, so letting first contact pin 52 of this attenuation units 5 that part is arranged is the inserting section 646 that protrudes out this small-bore portion 642.
Next; Should insert this linkage unit 3 by the large aperture portion 641 of this linkage unit 3 towards the direction of this small-bore portion 642 by plant part 4 equally; And cover at second contact pin, 53 outsides of this attenuation units 5, and block mutually with connecting hole 63 (see figure 2)s of this linkage unit 3 with said clamping block 43 (see figure 2)s and to establish connection, thus; The two ends of this attenuation units 5 all are fixed, and this attenuation units 5 stably is arranged in this linkage unit 3.
When using this fibre optic attenuator 2; Be that an optical fiber transmission line 71 is engaged with second contact pin 53 of this attenuation units 5, and push the force section 33 of this linkage unit 3, make this pressure bullet portion 31 drive said projection 32 and move down; Move to position like imaginary line among Fig. 4; Just can insert a communicator 72 afterwards, discharge this force section 33 at last again, make this pressure bullet portion 31 drive to move on the said projection 32 and reset with this plug spare 62; Said projection 32 will be embedded into this communicator 72, so this fibre optic attenuator 2 just with these communicator 72 Joints.Need to prove that this optical fiber transmission line 71 is to use LC optical fiber in the present embodiment.
Because the plug spare 62 and the socket piece 61 of this housing 6 are one-body molded; Structural strength is high, therefore after long-time the use, does not also have the situation that misplaces or get loose during plug; More can not produce the gap and influence the force section 33 of this housing 6 and the continuous action relation of pressure bullet portion 31; And the uneven surface 331 of this force section 33 can provide more friction force when pushing, and is difficult for slippage in the operation, more increases the stability when installing.
In sum, the utility model fibre optic attenuator 2 improves structural strength through plug spare 62 and socket piece 61 one-body molded processing with this housing 6, and does not also have the problem of becoming flexible or producing the gap after long-time the use.
