Embodiment
Like Fig. 1～shown in Figure 4; The joints of optical fibre of the present invention comprise contact pin body 1, contact pin positioning seat 2, the thrust unit 3 that is connected the end of adaptive optical cable by being used to of setting gradually behind the forward direction; Contact pin body 1, contact pin positioning seat 2, thrust unit 3 are the bluff body of the height dimension in cross section greater than width dimensions; Be respectively equipped with in contact pin positioning seat 2, the thrust unit 3 and connect the cable passage 9 that confession optical cable both front/rear ends, that mutual correspondence communicates wears; Contact pin body 1 rear end is fixed on the front end of contact pin positioning seat 2 through the location pilot pin 6 of its both sides, ribbon fiber 4 insert and insert from the cable inlet of thrust unit 3 tail ends wear thrust unit 3, contact pin positioning seat 2 is connected with contact pin body 1.Elasticity is fixed with symmetrically arranged two locking keys that extend back 7 on the outside surface of thrust unit 3 relative both sides.
The rear end one of contact pin positioning seat 2 extends back and is provided with two guide pillars 21 that are symmetricly set in the both sides, cable passage; The front end correspondence of thrust unit 3 is provided with two pilot holes 31; The rearward end of described two guide pillars 21 is slided and is inserted in each corresponding pilot hole 31; The middle part of guide pillar 21 offers the slotted hole 22 of perforation guide pillar 21 relative two lateral circle surfaces that extend from front to back; Be fixed with the radially slotting pin 33 of wearing said pilot hole 31 on the said thrust unit 3 along pilot hole; Said pin 33 is threaded onto in the slotted hole 22 on the guide pillar 21 that gets in the corresponding pilot hole 31 simultaneously, the hole wall of the slotted hole 22 rear and front ends 33 pushing tow blocks of when moving to pin 33 positions, being pinned.In each pilot hole 31 spring 5 is housed, spring 5 is the flexible volute spring of fore-and-aft direction, and said guide pillar 21 rear end faces cooperate with spring 5 front end pushing tows, and the rear end of spring 5 cooperates with pushing tow end face 32 pushing tows that pilot hole 31 rear ends are provided with.
Because contact pin positioning seat 2 is bigger with the size of thrust unit 3 on short transverse, said guide pillar 21 and corresponding pilot hole 31 are arranged near near the edge of the dual-side on the height dimension direction of contact pin positioning seat, thrust unit.When the joints of optical fibre use, spring 5 can with contact pin positioning seat 2 and thrust unit 3 to be separated from each other forward, towards the rear to backing down, realize that contact pin positioning seat 2 is connected with the elasticity of thrust unit 3 on fore-and-aft direction.And the block between the pin of the slotted hole on the guide pillar and thrust unit cooperates and can guarantee that contact pin positioning seat 2 can not arbitrarily come off from thrust unit 3.
Be provided with two pin mounting grooves 23 on the outside surface of contact pin positioning seat 2 front ends one side side by side; Be provided with the axial limiting bayonet socket that cooperates with the eel-like figure axle journal of locating pilot pin 6 afterbodys in the pin mounting groove 23; Make location pilot pin 6 afterbodys pack in the pin mounting groove 23 and axially by locked, the head of location pilot pin 6 is plugged on the pin-and-hole corresponding on the contact pin body 1 after the front end face of contact pin positioning seat 2 passes.
Be used for and the spacing limiting section that cooperates of the slotted hole of guide pillar that is provided with in the pilot hole in the foregoing description is pin; Certainly in other embodiments limiting section also can adopt structures such as the hangnail that radially is convexly set on the pilot hole inwall, projection, and the slotted hole of guide pillar can be contained on the limiting section with strong dress mode or elasticity fashion of extrusion.
