Embodiment
To combine accompanying drawing and embodiment that the joints of optical fibre of the present invention are done further to specify below.
See also Fig. 2, it is for the joints of optical fibre 200 of preferred embodiment of the present invention.These joints of optical fibre 200 comprise fore shell 20, sleeve pipe 21, flange 22, spring 23 and back cover 24.
See also Fig. 3 and Fig. 4, fore shell 20 comprises a strip hollow body 201.The cross section of this hollow body 201 is square and this hollow body comprises four interconnective sidewalls.Body 201 one of them sidewall one end extend to form a door bolt the arm 203 and other end of body 201 forms first holding section 205 to body 201 length directions.This door bolt arm 203 has a convexity 2031, so that the joints of optical fibre 200 insert adapters when (figure does not show), the convexity 2031 of door bolt arm 203 and the groove fit on the adapter are fixed the joints of optical fibre 200 and adapter.This first holding section 205 is used for matching with back cover 24, and offers relative locking holes 2051 and a groove 2053 on this first holding section 205.Locking holes 2051 be positioned on the sidewall adjacent with door bolt arm 203 and this locking holes 2051 for square.This groove 2053 be opened on the sidewall of body 201 at door bolt arm 203 place and its bearing of trend identical with body 201 length directions.And, these body 201 inboard convexities 207 that form.
During assembling, sleeve pipe 21 is fixedly arranged on the opening of flange 22, and optical fiber (figure does not show) passes through hole 245, spring 23 spring coils, the through hole 227 of flange 22 and the through hole 211 of sleeve pipe 21 of back cover 24 successively, and is fixed in sleeve pipe 21 through holes 211.Spring 23 is sheathed on the guide pillar 223 of flange 22, and in guide pillar 223 is accommodated in the opening 2425 of second holding section 242.When the cavity of fore shells 20 was inserted in second holding section 242 of back cover 24, groove 2053 elasticity were opened and are made snap fit tabs 2423 and locking holes 2051 corresponding engagings.At this moment, spring 23 1 end bias voltage flange bases 22 make it to support the internal protrusion 207 of fore shell 20, and the other end of spring 23 supports shoulder 247.And sleeve pipe 21 can be slided along the length direction of fore shell 20.
Fore shell 20 is a plastic cement material, and is one-body molded by double teeming mouth injection, on the side relative with door bolt arm 203 that two cast gates are located at fore shell 20 separated by a distancely, and guarantees to have at least near a cast gate is positioned at directly over the locking holes 2051.Plastic cement with fusion injects die cavity by cast gate then, and the plastic cement of fusion will flow to locking holes 2051 positions by gate location.Because the position corresponding to locking holes 2051 in the die cavity is a convexity, like this, melt plastic cement stream is divided into two tributaries by convexity and walks around convexity and join, and promptly forms weld bond 208 after the position cooling of its junction.This weld bond 208 extends from the locking holes 201s along the length direction perpendicular to fore shell 20 bodies 201.
When fore shell 20 cavitys are inserted in second holding section 242; Second holding section, 242 extruding first holding section, 205 outer walls also make it produce tension; Because weld bond 208 is by setting out near the locking holes 2051 along extending perpendicular to fore shell 20 length directions, first holding section, 205 outer wall tension directions are consistent with the weld bond bearing of trend, and weld bond 208 and first holding section, 205 end faces do not have intersection point; So first holding section all position intensity of 205 end faces are all higher, so be difficult for taking place cracking phenomena.
Because when injection adopted the double teeming mouth, the injection volume when each waters the gate material injection volume much smaller than single cast gate injection is so formed stub bar is very little after its moulding; Just removed automatically during die sinking by slide block; Need not to carry out extra stub bar excision program, produces more conveniently, the while has also been reduced cost.
Be appreciated that; First holding section 205 also can be arranged at back cover 24, the second holding sections 242 also can be arranged at back fore shell 20, supposes that promptly fore shell 20 is first housing and back cover 24 is second housing; Then first holding section 205 both can be arranged at first housing, also can be arranged at second housing; If hypothesis back cover 24 is first housing and fore shell 20 is second housing, then first holding section 205 both can be arranged at first housing, also can be arranged at second housing.
Cast gate when being appreciated that injection more than two can reach same effect equally.
