In the such scheme, the ceramics pole or the Ceramic Balls of inlaying on the described insulation sleeve are uniformly distributed along the circumference, and ceramics pole or Ceramic Balls on the insulating washer also are uniformly distributed along the circumference.
In the such scheme, on the rail head of described fiber end post, be inlaid with 3-4 ceramics pole or Ceramic Balls, on its flange of rail, be inlaid with 8-10 ceramics pole or Ceramic Balls.
In the such scheme, offering apart from the top the nearer oblique grooving of evagination circular arc on nearer horizontal grooving, 2 distances, 2 on the rail head of described fiber end post apart from the nearer vertical grooving of side.
In the such scheme, described grooving is offered in thickness direction both sides symmetry, and thickness stays 1-2mm behind the grooving.
In the such scheme, the concrete structure that described insulation sleeve and insulating washer are connected as a single entity is: insulation sleeve penetrates insulating washer and bonding with the inner hole wall of insulating washer.
In the such scheme, ceramics pole or Ceramic Balls are that diameter is micro-crystalline ceramic post or the micro-crystalline ceramic ball of 2-8mm in the described aperture, and bonding with hole wall.
Railway track joint insulation coupling assembling of the present utility model has the following advantages compared with prior art:
1, mosaic bonding has durable micro-crystalline ceramic post or micro-crystalline ceramic ball in the thickness direction of original insulation assembly, make the strength character of rail joint insulation coupling assembling significantly improve, its abrasion resistance, resistance to pressure, weatherability combination properties such as (100 ℃～+ 90 ℃) increase.
2, the rail head outward flange of fiber end post is offered grooving, helps adapting to the profile of relayable rail, is difficult for making the fiber end post fracture, has protected the electrical insulation capability of joint, reduces accident potential.

The specific embodiment
Below in conjunction with drawings and Examples, further specify the utility model.
With reference to Fig. 1-Fig. 2, railway track joint insulation coupling assembling of the present utility model comprises: the fiber end post 9 of liner between rail 1 and rail 1 termination, the groove typed insulation plate 5 of liner between rail 1 and splice bar 2, liner in the fish-bolt connecting hole insulation sleeve 4 and the insulating washer 6 outside the hole, couple together by bolt 3, packing ring 7 and nut 8.With reference to Fig. 3-Fig. 9, improvements of the present utility model are, insulation sleeve 4, insulating washer 6 adopt glass-reinforced plastic materials to make, and insulation sleeve 4 penetrates insulating washer 6 and bonding with the inner hole wall of insulating washer 6; On the tube wall of insulation sleeve 4, offer aperture, in aperture, be inlaid with 8 Φ, 4 micro-crystalline ceramic posts 10; On insulating washer 6, be inlaid with 3 Φ, 4 micro-crystalline ceramic posts 10; Micro-crystalline ceramic post 10 can evenly distribute along circumference, and bonding with hole wall; Groove typed insulation plate 5 can change little to width be 80-90mm, in bottom on the groove typed insulation plate 5, respectively be inlaid with 1 Φ, 5 micro-crystalline ceramic posts 11, and thereon bolt hole 12 around be inlaid with 2 Φ, 5 micro-crystalline ceramic posts 11 (Figure 7 shows that 3 groove typed insulation plates); On the rail head 14 of fiber end post 9 and the flange of rail 15, respectively be inlaid with 3 Φ, 8 micro-crystalline ceramic posts 13 and 8 Φ 8 micro-crystalline ceramic posts 13.
