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 rear end of guide pillar 21 is provided with symmetry and is convexly set in two hook portions 26 on the guide pillar side face; Between two hook portions 26, be provided with in the guide pillar 21 guide pillar 21 rear sections are divided into straight joint 25 two elastic cantilevers, that extand rearward to the guide pillar rear end, said each hook portion respectively is arranged on the elastic cantilever and is able to upwards realize actuating in the footpath of guide pillar.Symmetry offers and each pilot hole 31 corresponding slotted holes 33 along the fore-and-aft direction extension that communicate on the outside surface of thrust unit 3 both sides; A pair of slotted hole 33 corresponding pilot holes 31; And the symmetrically arranged hook portion 26 corresponding slip insertings on said each guide pillar 21 are in a pair of slotted hole 33; The end face that each hook portion 26 front end has forward is used for cooperating with the hole wall block backwards of slotted hole 33 front ends, and hook portion 26 rear ends have the inclined-plane that reduces gradually backward of being convenient to get into slotted hole 33.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 ends are provided with the jack 24 that communicates with said straight joint of inserting spring 5 front ends, and jack 24 front ends are provided with pushing tow end face 22 and cooperate with the spring 5 front end pushing tows that insert.The rear end of spring 5 freely is in the rear portion of corresponding pilot hole 31, and pushing tow end face 32 pushing tows that under the effect that thrust is arranged, are provided with the pilot hole rear end cooperate.When contact pin positioning seat 2 makes up with thrust unit 3; Said elastic cantilever on the guide pillar 21 can clamp-on in the pilot hole 31 hook portion 26 near gathering in opposite directions; When making its hook portion 26 arrive the position at slotted hole 33 places of pilot holes 31 when promoting guide pillar 21 to move backward; Hook portion 26 gets in the slotted holes 33 and compressed elastic cantilever before discharging, and realizes in the slotted hole 33 cooperating with the anti-avulsion of slotted hole 33 and hook portion 26 is remained on, and the very convenient and anti-avulsion connection of combinations thereof fitting operation reliably; When needs split contact pin positioning seat 2 with thrust unit 3, to push hook portion 26 and be retracted in the inner pilot hole 31 of slotted hole 33, pulling contact pin positioning seat 2 is also taken guide pillar 21 out of and can be realized splitting, and fractured operation is very convenient.

Because contact pin positioning seat 2 is bigger with the size of thrust unit 3 on short transverse, said guide pillar 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 hook portion on the guide pillar cooperates with the block of the slotted hole of thrust unit and can guarantee that contact pin positioning seat 2 can not arbitrarily come off from thrust unit 3.

Contact pin positioning seat 2 front ends are respectively equipped with a pin mounting groove 23 on the outside surface of the relative both sides on the short transverse; 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.

Thrust unit 3 middle parts on the outside surface of the relative both sides on the short transverse respectively elasticity be fixed with the locking key 7 that is used for the spacing cooperation of adaptive jack buckle; Each locking key 7 front end is connected on the thrust unit 3; Locking key 7 rear ends elasticity backward are suspended in thrust unit 3 outside surfaces top; The outside, the rear end of locking key 7 is provided with the finger that has band and touches protrudingly 71, and the outside, middle part of locking key 7 is provided with and is used for the hangnail 72 that the spacing recess with adaptive jack is clasped.Thrust unit 3 front end outside surfaces are provided with and place said one of them locking key 7 feather key 8 along the fore-and-aft direction extension before.
