The invention discloses an optical fiber three-way connector with a plaster recess, consisting of a connector (1), a signal input terminal (2), a signal output terminal (3), a filtering installation rack (4), and a filtering sheet (5); the optical fiber three-way connector main body is of a hollowed rotating metal structure; the connector (1) and the signal input terminal (2) belongs to the coaxial rotating body; and the filtering installation rack (4) is fixedly installed on the intersection point of the central axis of the signal output terminal (3) and the central axis of the signal input terminal (2). The optical fiber three-way connector with a plaster recess is characterized in that the parallel distance between reflection line of the central axis of the upper surface of the filtering installation rack (4) and the signal input terminal (2) and the central axis of the signal output terminal (3) is 0.155+-0.02 mm. The four recesses arranged on the filtering installation rack and the filtering sheet adopting four point stress plastering can effectively prevent the warping during the installation process, and the red light adverse can be greatly improved and raised.
Description
Technical field
The present invention relates to technical field of optical fiber communication, particularly relate to a kind of optical fiber three-way connection with paster pit.
Background technology
Optical fiber communication is using light as information carrier, using optical fiber as the communication mode of transmission medium, first converts the electrical signal to light signal, then is transmitted by light signal through optical fiber, belongs to the one of wire communication.Light just can carry information after modulation.Fiber-optic communications traffic capacity is large, the advantages such as good confidentiality.Wherein light sender is responsible for signal being transformed into the light signal being suitable for transmitting on optical fiber, fibre circuit is responsible for signal transmission, and light receiver is responsible for receiving optical signals, and therefrom information extraction, then be transformed into electric signal, finally obtain the corresponding information such as speech, image, data.General optical fiber loses smaller on the line when linear transmission, but when optical fiber needs to be branched off into branch line from main line, particularly optical fiber is when carrying out 90 degree of conversions, need fibre-optical splice threeway, and common optical fiber threeway is in manufacturing process, due to the precision problem of joint paster, have a strong impact on the signal stabilization of optical fiber in communication process, especially easily produce the bad phenomenon of ruddiness, therefore, in order to overcome the above problems, need to be optimized design to the mounting means of adapter paster, ensure communication quality.
Summary of the invention
According to above-mentioned defect, the object of the present invention is to provide a kind of optical fiber three-way connection with paster pit, by the adjustment of the installation fixed form to paster, greatly improve the stability that light signal passes through, improve product one-pass finished rate, cut down finished cost.
Technical scheme of the present invention is achieved in the following ways: a kind of optical fiber three-way connection with paster pit, by link, signal input port end, signal outlet end, filtering erecting frame, filter plate forms, optical fiber three-way connection main body is hollow solid of revolution metal construction, link and signal input port end are coaxial rotating body, link inside is provided with three grades of ledge structures, signal input port end outer setting has boss structure, signal outlet end axis is vertical with signal input port end axis with link, filtering erecting frame is fixed on signal outlet end axis and link and signal input port end axis position of intersecting point, filtering erecting frame be a planar structure and surface level in angle of 45 degrees, its upper surface is vertical with the face that two axis are formed, it is characterized in that: the reflected ray of described filtering erecting frame upper surface and link and signal input port end axis is 0.155 ± 0.02mm with the parallel distance of signal outlet end axis.
Be provided with signal by mouth in the middle of described filtering erecting frame upper surface, signal is respectively arranged with the square pit of a 0.15mm degree of depth by mouth both sides, and filter plate is arranged on above two square pits, the covering of completely filtered of square pit.
The present invention, by being arranged on the pit on filtering erecting frame, can reducing the contact area that filter plate is installed, adopting 4 stressed stickups, while guarantee installation quality, effectively can prevent the warpage in installation process from occurring, improve one-pass finished rate.
