Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
As shown in Figure 1, traditional joints of optical fibre do not have straight curved formula structure, and the installing space of needs is comparatively large, is not suitable for using under narrow space environment.Use under vehicle-mounted environment such as narrow space such as grade to enable the joints of optical fibre, under the condition not changing connector shell and guarantee connector optical property, mechanical property and environmental performance, adopt split-type structural, devise a kind of joints of optical fibre as shown in Figure 1, instead of old-fashioned single tail nested structure, achieve the function of joints of optical fibre right-angle bending.
As shown in Fig. 2 to Fig. 4, a kind of joints of optical fibre of the present embodiment comprise light contact pin 1, housing 2, tail cover 4, cable jacket 5, optical fiber 6 and fibre-optical splice 7, the pin portion of light contact pin 1 is arranged on outside housing 2, the lower body of light contact pin 1 is in housing 2, the optical fiber 6 of light contact pin 1 is successively by housing 2, tail cover 4, cable jacket 5 is to fibre-optical splice 7, also comprise buffering cavity 3, described buffering cavity 3 is arranged between housing 2 and tail cover 4, form right angle structure in 90 ° is overlapped with tail, buffering cavity 3 and tail cover 4 are threaded, buffering cavity 3 inside arranges position limiting structure, optical fiber 6 realizes bending by position limiting structure.
The lower body of light contact pin 1 is arranged contact pin spring 8, the afterbody of light contact pin 1 arranges contact pin tail cap 10, the rear of contact pin tail cap 10 arranges push pedal 11, described position limiting structure comprises L bar 14 and motion bar 15, the inflection point place of L bar 14 is rotationally connected by rotating shaft 13 and buffering cavity 3 inwall, one end of L bar 14 is against in push pedal 11, the other end is fixedly connected with one end of motion bar 15, described L bar 14 is provided with groove I away from the end, one end of push pedal 11, one is connected for overlapping the cylinder of optical fiber by axis of rotation in groove I, described motion bar 15 is provided with groove II away from the end, one end of L bar 14, one is connected for overlapping the cylinder of optical fiber by axis of rotation equally in groove II, can contact pin tail cap 10 be promoted by contact pin spring 8 and then promote push pedal 11 when light contact pin 1 moves backward, the moment that push pedal 11 acts on L bar 14 makes L bar 13 rotate around the shaft.
The straight curved formula joints of optical fibre of the present embodiment are four-cores, arrange two groups of position limiting structures, and namely a L bar 14 and motion bar 15 are one group of position limiting structure.
Also comprise spring stop 9, spring stop 9 is arranged on the rear of contact pin spring 8, and it is inner that spring stop 9 is fastened on housing 2 with trip bolt 16, and spring stop 9 compresses contact pin spring 8, ensure elastic force when light contact pin 1 docks, after pulling the plug out of the socket, make light contact pin 1 return simultaneously.
Also comprise gib screw 17 and push pedal spring 12, push pedal spring 12 is arranged on gib screw 17, and gib screw 17 is fixed on push pedal 11 on spring stop 9, and push pedal spring 12 is for push pedal 11 return.
Rotating shaft 13 between L bar 14 and motion bar 15 supports optical fibre, need determine its external diameter according to the bending radius of optical fiber, and the pass between rotating shaft 13 diameter D and fiber bending radius r is: D/2 >=r.
In the joints of optical fibre mating process of the present embodiment, light lock pin 1 docks resilience, promote contact pin tail cap 10 by contact pin spring 8 to move backward, contact pin tail cap 10 promotes the motion of push pedal 11 backward directions, the moment that push pedal 11 acts on L bar 14 makes L bar 14 13 rotations around the shaft, then motion bar 15 rotates around L bar 14 and moves up backward, gives optical fiber with enough curved spaces; When in joints of optical fibre detachment process, contact pin spring 8 makes light contact pin 1 return, and push pedal 11 loses the acting force of contact pin tail cap 10, return under the elastic force effect of push pedal spring 12, now, L bar 14 loses moment loading, get back to initial position, give the optical fiber 6 shortened with the curved space.
As from the foregoing, as shown in Figure 1, traditional four-core fiber connector, plug, socket directly overlap 4 with tail and are connected, optical fiber straight is arranged on connector inside, because tail cover is fixed, therefore, when plug and socket connects installation with optical cable junction, little bending can be there is in optical fiber in plug inside, need during making to control optical fiber excess length, this easily reserves suitable surplus, for fibre-optical bending in traditional straight tail cover inside.In the straight curved formula structure of the present embodiment, as shown in Figure 3 and Figure 4, because tail overlaps 4 short and right-angle structures in 90 °, if still adopt traditional design, the surplus of optical fiber is difficult to control, floating due to lock pin during installation, easily causes the impaired and even fracture of optical fiber.Therefore, the design concept of the straight curved formula joints of optical fibre of the present embodiment adopts split-type structural design, independently buffer fiber cavity 3 is adopted to carry out the shifting amount introduced when receiving optical fiber lock pin floats, when connector inserting or when being separated, spring floating structure normally works, optical fiber back and forth can only buffering cavity in play.
Secondly, according to the minimum bending radius of optical fiber, design the stop means of limit fibre bending radius, like this, light contact pin 1, connecting very little with the amount of floating introduced when being separated the impact of optical fiber 6, fractures because bending radius is too small or affects light loss when preventing optical fiber 6 play.
In actual applications, as in onboard system, do not have larger installing space available, the joints of optical fibre of the present invention adopt split-type structural design, and can at a right anglely bend, the installing space of needs is less, can use under narrow space environment.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
