Summary of the invention

The object of the present invention is to provide a kind of simple in structure, joints of optical fibre that the contact pin positioning seat is connected with pushing in device elasticity.

Technical scheme of the present invention is: a kind of joints of optical fibre; Comprise by the contact pin body, contact pin positioning seat, the thrust unit that are used to be connected the optical cable end that set gradually behind the forward direction; Be respectively equipped with in contact pin positioning seat, the thrust unit and connect the cable passage that confession optical cable both front/rear ends, that mutual correspondence communicates wears; Be fixed with the elastic device that is used for providing the elastic force on the fore-and-aft direction between the opposing end surface of said contact pin positioning seat and thrust unit between the two; Said elastic device is a pair of arc spring lamination that is symmetrically distributed in said cable passage both sides, and the forward and backward two ends of each arc spring lamination are connected with the front end face of contact pin positioning seat rear end face, thrust unit respectively.

The convex surface of the arch section of said two arc spring laminations is towards the joints of optical fibre outside.

Elasticity is fixed with symmetrically arranged two locking keys that are used for the spacing cooperation of adaptive jack buckle on the outside surface of the relative both sides of said thrust unit; Each locking key front end is connected on the thrust unit; Rear end elasticity backward is suspended in thrust unit outside surface top; The outside, the rear end of locking key is provided with the finger that has band and touches convexity, and the outside, middle part of locking key is provided with and is used for the hangnail that the spacing recess with adaptive jack is clasped.

The outside surface of said thrust unit front end is provided with and places the said locking key feather key along the fore-and-aft direction extension before.

Said contact pin body, contact pin positioning seat, thrust unit are the bluff body of the height dimension in cross section greater than width dimensions, and the link position of said arc spring lamination and contact pin positioning seat, thrust unit is near the edge part on the height dimension direction of contact pin positioning seat, thrust unit.

The contact pin positioning seat that front and back of the present invention are provided with realizes that through the arc spring lamination that is connected elasticity is connected with pushing in device between the two; Thereby the contact pin positioning seat that satisfies the joints of optical fibre can and be linked to be whole demand simultaneously with respect to the pushing in device elastic floating; Make fibre-optic connector structure of the present invention compact, easy to assembly.

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.

Be fixed with the elastic device that is used for providing the elastic force on the fore-and-aft direction between the opposing end surface of contact pin positioning seat 2 and thrust unit 3 between the two; Said elastic device is to be symmetrically distributed in the arc spring lamination 5 that the arch section of said cable passage both sides turns up; The forward and backward two ends of arc spring lamination 5 link together through fixing fit with the front end face of the rear end face of contact pin positioning seat 2, thrust unit 3 respectively; Fixedly fit can adopt interference inserting, usual way such as bonding; Because contact pin positioning seat 2 is bigger with the size of thrust unit 3 on short transverse, the link position of said arc spring lamination 5 and contact pin positioning seat, thrust unit is near the edge part on the height dimension direction of contact pin positioning seat, thrust unit.When the joints of optical fibre use, arc spring lamination 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.
