Description

A kind of HDMI1.4 types photoelectric hybrid connector connection component

Technical field

The invention belongs to optical fiber electric and communication technical field, more particularly to a kind of type photoelectric hybrid connectors of HDMI 1.4 Connection component.

Background technology

With the arriving of information age new century, Impact of Information Technology and change people's mode of production and life style, Important impetus amount as modern Economy Development.Communication has penetrated into the Working Life of people and side's aspect of social economy Face.Faster, more convenient under this overall background, more practical communications connector product is the hair of current communications connector product Open up direction.

Advantage of the joints of optical fibre compared with typical electrical connector is that it has electromagnetism interference good, and efficiency of transmission is high, Unique advantage such as small volume, therefore it is widely used in fiber optic communication field.Being mainly used for of the joints of optical fibre is used to Realize continuing for optical fiber.And the difference of AOC photoelectric hybrid connectors and the existing joints of optical fibre is, can with it is existing integrated The supporting integration of circuit is used, and photoelectric conversion module integrated circuit is installed carries out light without equipment is used alone in the connectors Electricity conversion, saves data center, the space such as large-scale computer room, while can be compatible with the terminal device such as existing computer, so as to gather around There are extensive market prospects.In joints of optical fibre field, jointing is used for the connection gripped with optical fiber of optical cable, existing Jointing limited by structure, joint endurance and chucking power it is smaller, easy stress deformation, joint pull stress when can make light Fine stress, this will influence the switching performance of optical fiber, or even make optical fiber impaired and influence its transmission performance.Therefore, existing optical fiber Connector is also difficult in adapt to the use environment requirement for needing often to plug and pull.The newest standards of HDMI 1.4 require that realization is higher Transmission rate, and communications electronics product to the tension of optical cable, bend resistance, anti-extrusion ability demand, to data transmission light Cable proposes higher requirement.This demand has given the optical-fiber type connectors of HDMI 1.4 bigger broader development space.

The content of the invention

The present invention provides a kind of type photoelectric hybrid connector connection components of HDMI 1.4, it is easy to assembles, can meet autgmentability Demand, tensile property is strong, and reliability is high, and tolerance is strong.

The present invention solves the technical scheme that is used of above-mentioned technical problem:A kind of type photoelectric hybrid connectors of HDMI 1.4 Connection component, includes jointing, and the jointing is connected with the both sides termination of optical cable respectively, in addition to installs connection and connect The connector encapsulating shell of head, it is characterised in that the jointing includes tubular connector body and crimping annulus, the tubular configured joint Body front end is provided with crimping seat, and rear end leads to provided with locking caudal peduncle, the crimping annulus with the locking caudal peduncle phase configuration, locking caudal peduncle Cross crimping annulus with tail protective case to be connected, the locking caudal peduncle periphery of tubular connector body is provided with stop lug or screw thread, crimping circle Ring is that cylindrical tube structure is connected with locking caudal peduncle pressing, and the optical cable is tension high speed fibre data transfer optical cable, is included Oversheath and the optical fiber being coated in the oversheath, are also wrapped on insulated metal wire and filling enhancement layer in oversheath, The insulated metal wire is made up of multiple single wires, and described filling enhancement layer is made up of the filling of aramid fiber rope.

By such scheme, the endoporus of the tail protective case is divided into two sections, leading portion aperture it is larger and be provided with Elastic buckle or Screw thread, with crimping annulus phase configuration, back segment aperture reduces the external diameter phase configuration with optical cable.

By such scheme, the optical fiber is tight tube fiber or resin coated fiber.

By such scheme, the optical fiber is single-mode fiber or multimode fibre, and optical fiber property meets the biography of the propositions of HDMI 1.4 Defeated speed and long range transmission attenuation performance requirement, 850nm windows transmission bandwidth is more than 200MHz*Km, and the transmission of 850nm windows declines Reduce in 5dB/Km.

By such scheme, the insulated metal wire is enamel covered wire, the insulated metal wire included in optical cable for 2~ 6, a diameter of 0.2mm~0.4mm of single plain conductor, lay mode of the plain conductor in optical cable is stranded or flat Paving, often thoroughly does away with edge plain conductor outsourcing insulation;The aramid fiber rope is provided with 3~8, the paving mode in oversheath Directly to put or stranded.

By such scheme, the connector encapsulating shell includes the upper and lower casing up and down to Semi-folding of prolate shape, in institute State in upper and lower shell body and tail sleeve groove, crimp groove and photoelectric conversion module mounting groove are disposed with from tail end to front end;It is upper and lower Also corresponded between housing and offer connecting screw hole, fastened and be connected by screw;The jointing for having crimped optical cable loads encapsulating shell, The crimping seat and tail protective case of the jointing and the tail sleeve groove and crimp groove difference phase configuration.

By such scheme, it is correspondingly arranged in the middle part of the photoelectric conversion module mounting groove in the upper and lower shell body inside convex Photoelectric conversion module mounting groove is separated into former and later two cavitys by platform, the boss.

By such scheme, the tubular connector body and crimping annulus are made by metal material;Described tail protective case by Plastics are made.

The beneficial effects of the invention are as follows:1st, enhancement layer will be filled in optical cable and outer jointing jacket is pressed on flanged tubular configured joint Between the locking caudal peduncle and crimping annulus of body, apply lateral pressure to crimping annulus so that crimp closely, not only with crimping Simply, the characteristic such as connection reliability, lossless to optical fiber, and tension resistance performance is strong, is resistant to more severe use environment, it is ensured that even The using effect steady in a long-term of joint;2nd, optical fiber and photoelectric conversion module are fixed in connector encapsulating shell, there is corresponding Position is accurately fixed, and convenient installation, and connector encapsulating shell can also act as the function of welding tooling;3rd, can be achieved 200 meters with The interior high transfer rates of HDMI 1.4 requirement, realizes the hot plugs of two ends HDMI 1.4;4th, it is applied widely, it is applicable not only to optical fiber Connector, is also applied for various other style connectors, and tensile strength is high, and the needs that are particularly suitable for use in repeatedly are plugged simultaneously by pulling force Larger connector.
