Abstract
The invention discloses an optical fiber contact element, which comprises a contact pin, wherein the rear end of the contact pin is spliced and fixed in a flange; the contact pin is provided with a fixed ring, a spring and a moving ring in turn from front to back; the fixed ring is fixed on the contact pin; the spring and the moving ring are axially and movably sleeved on the contact pin; the front end and the rear end of the spring stop and limit axially by the fixed ring and the moving ring respectively; and the moving ring has an axial stop fit structure. By adopting the axial size of the contact pin self as a spring mounting and expanding space, the optical fiber contact element saves the axial length required by the prior flange, thereby having more compact layout and consequently meeting the requirements of axial size reduction and miniaturized design.
Description
Technical field
The present invention relates to joints of optical fibre technical field, especially a kind of optical fiber contact.
Background technology
Existing optical connector is made up of plug and socket, be equipped with in the plug and socket with optical cable in the optical fiber contact that is connected of optical fiber, optical fiber contact comprises with optical fiber and directly docks contact pin and the contact pin annex that contacts.End force during for the butt joint of maintenance contact pin; In the existing fiber contact element generally and the ring flange that is connected of contact pin afterbody and its outside external member between elastomeric element is set; Elastomeric element is generally spring; The spring of existing optical fiber contact generally is sleeved on the ring flange rear portion; Therefore ring flange need be provided with certain axial length specially and guarantee the flexible of spring; Cause the ring flange axial dimension greatly also to have influence on the axial dimension of optical fiber contact owing to the shared axial space of spring is more, and in the current joints of optical fibre and the contact pin thereof quite a few be just towards the trend development of microminiaturization, the shortcoming that the axial dimension of existing contact element is bigger can not adapt to the requirement of miniaturized design.
Summary of the invention
The object of the present invention is to provide a kind of spring directly to be sleeved on the contact pin and make the optical fiber contact that layout is compact more, axial dimension is littler.
Technical scheme of the present invention is: a kind of optical fiber contact; Comprising contact pin, pegs graft and is fixed in the ring flange in the rear end of contact pin, on the said contact pin by being provided with retainer plate, spring, active ring behind the forward direction successively; Wherein retainer plate is fixed on the contact pin; The axial movable set of spring and active ring is on contact pin, and the rear and front end of spring can receive retainer plate respectively and the axial block of active ring is spacing, and said active ring is provided with axial stopping fit structure.
Said active ring receives the axial block of ring flange spacing.
Axial stopping fit structure on the said active ring is that the retaining that turns up on the active ring is along structure.
The step surface that faces the contact pin rear end that described retaining is provided with for the active ring outer ring along structure.
The spring of end force directly was sleeved on the contact pin when optical fiber contact of the present invention will keep the contact pin butt joint; And the front and back end in spring is provided with retainer plate and active ring in addition on contact pin; When with active ring during as the stopping block element of spring; End force in the time of just can realizing the elastic telescopic of retainer plate and contact pin and keep the contact pin butt joint; And the concrete axial stopping structure for realizing the axial stopping of active ring is to design according to the connector case body structure and the situation of stopping accessory of selecting for use; Axial stopping fit structure among the present invention on the active ring is meant the fit structure that on active ring, is provided with for matching connector housing or other stopping accessories, and the retaining that this axial stopping fit structure can be selected evagination is along the retaining groove of, stopping end face that overhanging bumping post, diameter is bigger, indent, pit or the like, and this class formation belongs to technological means commonly used; Need not in instructions, to detail one by one, therefore this class formation is referred to as axial stopping fit structure; The present invention is owing to utilized the axial dimension of contact pin itself to be used as the installation and the extendable room of spring; So just saved the axial length of required setting on original ring flange; Thereby make the layout of optical fiber contact of the present invention compact more, and then can satisfy the requirement that reduces axial dimension, miniaturized design.
In addition, the active ring that is sleeved on the contact pin of the present invention can be spacing by the ring flange block of back, is in order to prevent that active ring from coming off from contact pin like this.
In addition; Axial stopping fit structure of the present invention is the retaining edge of turning up; Along structure, this retaining can cooperate with the edge of retainer spring or connector back casing along structure retaining, thereby makes active ring become the stopping block element of spring along the retainings such as step surface that can select back-up ring or face the contact pin rear end.
Description of drawings

Embodiment
Optical fiber contact of the present invention comprises contact pin 1; Peg graft and be fixed in the ring flange 5 in the rear end of contact pin 1, by being set with retainer plate 2, spring 3, active ring 4 behind the forward direction successively, wherein retainer plate 2 is fixed on the contact pin 1 on the contact pin 1; Spring 3 and active ring 4 axial movable sets are on contact pin 1; The top, two ends of spring 3 is contained between retainer plate 2 and the active ring 4, and the rear end face of the active ring 4 of spring-loaded withstands on the ring flange 5, and the outer ring of active ring 4 is provided with the step surface 6 that faces contact pin 1 rear end.
Pack into the Kong Weihou of joints of optical fibre housing of optical fiber contact of the present invention; Can stop roof pressure by the edge of retainer spring or connector back casing on the step surface 6 of active ring 4, with the step surface backwards 6 of active ring 4 axial stopping locating surface as optical fiber contact.When contact pin 1 front end is under pressure contact pin body 1 rollback; The step surface 6 of active ring 4 can not be retreated by this moment that stops at the edge of retainer spring or connector back casing; Retreat and compression spring the end force when making contact pin 1 keep butt joint with contact pin 1 fixing retainer plate 2.
Claims (1)
1. optical fiber contact; Comprise contact pin; Peg graft and be fixed in the ring flange in the rear end of contact pin; It is characterized in that: by being provided with retainer plate, spring, active ring behind the forward direction successively, wherein retainer plate is fixedly set on the contact pin on the said contact pin, and the axial movable set of spring and active ring is on contact pin; The rear and front end of spring can receive retainer plate respectively and the axial block of active ring is spacing; Said active ring is provided with axial stopping fit structure, the axial stopping fit structure of said active ring be the retaining that turns up on the active ring along structure, retaining along structure for the active ring outer ring be provided with face the contact pin rear end, in use receive retainer spring or connector back casing the edge stop the step surface that can not retreat; Said ring flange front end is thinner along structure than said retaining, and the outer ring of the active ring between adaptive active ring rear end face to the step surface of ring flange front end face is narrower than the outer ring of retaining along the active ring at place, structure place.
