Description

Riveted formula Optical fiber plug

[technical field]

The utility model is about a kind of riveted formula Optical fiber plug.

[background technology]

Optical fiber is a kind of media that light signal transmission usefulness is provided, and optical fiber is when being connected with the point-to-point outside of other equipment, and an Optical fiber plug must be established as connector in its end.

The structure of the Optical fiber plug of commonly seeing at present as shown in Figure 7, two kinds of patterns such as short splice end and long splice end are generally arranged, with the short plug of tool is example, the Optical fiber plug of this inner hollow is fixed for the optical fiber cable 50 that will be arranged in the body 40 interior axis holes 41, at least one perforation 42 is set on its body 40 usually, and in this perforation 42, place the intermediate plate 43 of a tool perforation 431 in advance, coat optical fiber cable 50 that coating body 52 constituted when being arranged in the header body 40 axis hole 41 by optical fibre core 51 appearances, and pass in the perforation 431 of intermediate plate 43, by this, people can utilize tool to be pressurizeed up and down with respect to intermediate plate 43, make its intermediate plate 43 towards central compression deformation, force the perforation 431 of intermediate plate 43 to produce distortion, and the optical fiber cable 50 that will wear is wherein gripped.

Can find by preceding taking off in the Optical fiber plug structure, its header body must can riveted and fixed provide wherein optical fiber cable in conjunction with intermediate plate 43, its member is many, the cost height, and need during assembling the intermediate plate aligning is positioned in the perforation, urge intermediate plate riveted joint optical fiber cable with tool again, take a lot of work, trouble when invisible enhancement is assembled and cost expenditure because of its number of assembling steps is comparatively loaded down with trivial details, time-consuming.

Commonly use the Optical fiber plug shortcoming for what improve that aforementioned utilization adds that intermediate plate comes the riveted optical fiber cable, this case designer had before once designed a kind of riveted formula Optical fiber plug that does not have intermediate plate, as shown in Figure 8, it mainly is to make forming the groove 62 that at least one does not extend to interior axis hole 61 on the header body 60, allow wall thickness between 61 of groove 62 bottoms and interior axis holes as clamping part 63, use, provide behind the interior axis hole 61 of header body 60 in optical fiber cable 70, directly utilize tool to urge the distortion of groove 62 bottom clamping parts 63, and the coating body 71 that is butted on optical fiber cable 70 appearances is gripped.

Aforementioned no intermediate plate riveted formula Optical fiber plug design, though exempt the setting of intermediate plate, and can reduce member, simplify number of assembling steps etc., yet, behind this no intermediate plate riveted formula Optical fiber plug winding optical fiber cable, the deformation grip portion of its riveted optical fiber is positioned at opening bottom portion of groove outwardly, people can produce the indecency depressed deformation point of outward appearance via its riveted of the direct photopic vision of groove, the outward appearance of hindering this Optical fiber plug, and, may this Optical fiber plug of misidentification be the incomplete defective products of an outward appearance for the user who does not understand the Optical fiber plug structure.

[utility model content]

The purpose of this utility model is to provide a kind of riveted formula Optical fiber plug, removes to possess and exempts to be provided with intermediate plate, to reduce member, outside the functions such as simplification number of assembling steps, more can further hide the depressed deformation point of riveted, keeps the good looking appearance and the integrality of Optical fiber plug.

In order to achieve the above object, the utility model provides a kind of riveted formula Optical fiber plug, it has a header body, the Plug Division of this header body one side horizontal expansion one pipe shape, be provided with an interior axis hole that laterally runs through this header body in this header body centre, one optical fiber cable is arranged in this interior axis hole, it is characterized in that: should respectively establish at least one perforation that vertically runs through to both sides by interior aperture axis relatively on this header body, the sidewall of aperture axis between two side and two side perforations is provided with the clamping part of distortion in being somebody's turn to do, and grips this optical fiber cable with this clamping part.

Described riveted formula Optical fiber plug is characterized in that: can respectively establish a perforation with respect to aperture axis in this to both sides on this header body, aperture axis respectively has the clamping part of a distortion in this between the two side.

Described riveted formula Optical fiber plug is characterized in that: also can respectively establish two perforation that are axial array with respect to aperture axis in this to both sides on this header body, aperture axis can respectively have the clamping part of two distortion in this between the two side.

Riveted formula Optical fiber plug of the present utility model, its advantage is: its body side is provided with the Plug Division of a pipe shape, axis hole can wear wherein for optical fiber cable in it, and internal mutually aperture axis is respectively established at least one perforation that vertically runs through to both sides on the header body, the sidewall of interior aperture axis between two side and two side perforations is clamping part, in order to the deformation grip fixed fiber line after utilizing clamping part pressurized, and utilize retaining part to be difficult for the deformation point of seeing and locating in madial wall, the impression that further allows the Optical fiber plug outward appearance not manifest its pressurized riveted to be produced is kept the attractive in appearance and integrality of plug outward appearance.

For enabling further to understand architectural feature of the present utility model and other purposes, describe in detail as the back with the preferred embodiment conjunction with figs. now:
