The utility model discloses avoided letting the scarf joint piece take place the shape change too big lead to the crack and can't act on, make scarf joint piece and embedding hole scarf joint stability not enough, cause the defect that intensity is not enough that the form is not good, rabbet piece.
Description
Technical field
This utility model belongs to fiber cable joint device, is specifically related to a kind of enhancement mode fitting member for rubber-covered wire optical cable connection box.
Background technology
Covered wire cable mostly is single, twin-core structure, it is possible to make quadrature arrangement, and cross section is 8 fonts, and reinforcement is positioned at Liang Yuan center, can use metal or nonmetal structure, and optical fiber is positioned at the geometric center of 8 fonts.Covered wire cable inner fiber generally use G.657 small-bend radius optical fiber, can lay with the bending radius of 20mm, be suitable in building registering one's residence with pipe method or open wiring mode.
And the connection between existing covered wire cable is all by being attached for rubber-covered wire optical cable connection box, the box body of described connector box includes first half box body and lower half box body, it is typically between first half box body and lower half box body to connect through built-in brick and boarding hole and be combined into an entirety, when mounted, once the when of interlocking, interlocking effect is the least, built-in brick is often made to be difficult to imbed in boarding hole, even if built-in brick has imbedded boarding hole, or can allow built-in brick generation change of shape is excessive causes slight crack to act on, cause form the best；And once interlocking effect is little, usually making built-in brick and boarding hole interlocking stability inadequate, arise that space between first half box body and lower half box body, form is the best；So that maintenance cost strengthens.The additionally insufficient strength of built-in brick.
Summary of the invention
The purpose of this utility model provides a kind of enhancement mode for the fitting member of rubber-covered wire optical cable connection box, including joint box body, described joint box body includes first half box body and lower half box body, it is provided with scarf joint on described first half box body, boarding hole is had on described lower half box body, ditch road is had down on the edge surface of described boarding hole, the lower surface on described ditch road stretches out glass bronze block towards higher position, with the supporter arched upward in described boarding hole on the top of described glass bronze block, described scarf joint peaks on described supporter through described boarding hole, described scarf joint is stainless steel material, the rear portion of described scarf joint is with floor, the top of described floor is mutually smooth with the top of described scarf joint.Present invention, avoiding can allow built-in brick generation change of shape excessive cause slight crack and cannot act on, make built-in brick and boarding hole interlocking stability not, cause that form is the best, the defect of the insufficient strength of built-in brick.
In order to overcome deficiency of the prior art, this utility model provides a kind of enhancement mode solution for the fitting member of rubber-covered wire optical cable connection box, specific as follows:
A kind of enhancement mode is for the fitting member of rubber-covered wire optical cable connection box, including joint box body 1, described joint box body 1 includes first half box body 2 and lower half box body 3, it is provided with scarf joint 12 on described first half box body 2, boarding hole 13 is had on described lower half box body 3, ditch road 14 is had down on the edge surface of described boarding hole 13, the lower surface on described ditch road 14 stretches out glass bronze block 15 towards higher position, with the supporter 16 arched upward in described boarding hole 13 on the top of described glass bronze block 15, described scarf joint 12 peaks on described supporter 16 through described boarding hole 13, described scarf joint 12 is stainless steel material；The rear portion of described scarf joint 12 is with floor 17, and the top of described floor 17 is mutually smooth with the top of described scarf joint 12.
Operation principle of the present utility model is owing to arranging described glass bronze block 15 on described boarding hole 13, it is the structure that change of shape can occur under external force plus described glass bronze block 15, the hardness of additionally described scarf joint 12 is high, when so scarf joint 12 being imbedded boarding hole 13, scarf joint 12 will not occur change of shape, therefore scarf joint 12 will not occur that change of shape is excessive causes slight crack to act on when interlocking, keeps form complete；Additionally the described glass bronze block 15 on boarding hole 13 can occur change of shape when scarf joint 12 imbeds, and interlocking effect can regulate, it is possible to allows scarf joint 12 rabbet the most difficult so that stability is strong.During rabbeting, floor 17 is able to ensure that the intensity of scarf joint 12, thus allows scarf joint 12 that change of shape can not be occurred excessive.
