Abstract

The present invention relates to a contact device (20) for contact of an optical fibre with another optical fibre in another contact device (21), said contact devices being mutually identical and including contact device fastening means. This is achieved by providing the contact devices with locking shoulders (14, 15) that have gripping surfaces (17), and with a guide sleeve (10) and an external thread (19). When the contact devices are connected together, the guide sleeve (10) co-acts with ferrules (7, 24) enclosing the ends of said optical fibres for contact with one another.

Uppfinningen kommer nu att beskrivas närmare med hjälp av en föredragen utföringsform och med hänvisning till bifogade figurblad.The invention will now be described in more detail with the aid of a preferred embodiment and with reference to the accompanying figure sheets.

FIGURBESKRIVNING Figur 1 visar kontaktdonets olika byggelement i en snittvy till vänster om linjen A-A och till höger om linjen B-B.DESCRIPTION OF FIGURES Figure 1 shows the various building elements of the connector in a sectional view to the left of the line A-A and to the right of the line B-B.

Mellan linjerna A-A och B-B visas byggelementen med skymda konturer.Between lines A-A and B-B, the building elements are shown with obscured contours.

FÖREDRAGEN Um-Fönmssronm I figuren visas tvà kontaktdon innefattande identiska kmqgelement ihopsatta med kontakterade optofibrer, där ett cikulärt chassiemonterat kontaktdon 20 är utfört pà ett till kontaktdonet 20 varför i huvudsak endast byggelementen i det likformigt sätt som ett anslutet kontaktdon 21, chassiemonterade kontaktdonet 20 beskrivs nedan.PREFERRED Um-Fönmssronm The figure shows two connectors comprising identical coupling elements assembled with contacted optical fibers, where a cyclic chassis-mounted connector 20 is made on one of the connectors 20. .

Det chassiemonterade kontaktdonet 20 innefattar ett cylindriskt hölje 1 försett med en yttre gänga 19, som möjliggör fastsättning i en chassiplàt 11 exempelvis med hjälp av en vänster-mutter 12 och en höger-mutter 13. Gängan 19 kan även tjäna som en greppyta vid ihopkoppling och isärtagning av kontaktdonen. Höljet 1 pà det chassiemonterade kontaktdonet 20 har en smal del utgörande ett brytskydd 2 för en med ett fiberskydd 3 innesluten optofiber 4.The chassis-mounted connector 20 comprises a cylindrical housing 1 provided with an outer thread 19, which enables attachment to a chassis plate 11, for example by means of a left-hand nut 12 and a right-hand nut 13. The thread 19 can also serve as a gripping surface for coupling and disassembly of the connectors. The housing 1 of the chassis-mounted connector 20 has a narrow part constituting a break protection 2 for an optical fiber 4 enclosed with a fiber protection 3.

Höljet 1 är även anordnat för att kunna innesluta en ferrul för optofibern bestående av en för ller pà annat sätt fastgjord, en grövre cylindrisk del 5 i (I) vilken optofibern är' med sitt hölje fastlimmad, fastklämd eller pà annat sätt fastgjord och en fläns 6. En spiralfjäder 10 15 20 25 30 520 175 3 8 är anordnad att verka mellan flänsens vänstra ändplan 26 och ett ändplan 9 i det chassiemonterade kontaktdonet 20 för ett kontaktomràde. En liknande att trycka ferrulen mot spiralfjäder 23 verkar pà ferrulen 24. Med spiralfjädrarna 8 ett konstant utàt riktat tryck pà kontakt i och 23 kan dà utövas ferrulerna och. därmed fàs _ en god optisk kontaktomràdet i ett mellan de slipade, och kontaktade gränssnitt 16 sätt behandlade fiberändarna i det chassiemonterade kontaktdonet 20 och i kontaktdonet 21. polerade eller pà annat För styrning av ferrulens smala cylindriska del 7 i det chassiemonterade kontaktdonet 20 mot en smal cylindrisk del kontaktdonet 21, styrhylsa 10 pà de mot varandra verkande smala delarna 7 och 24 pà ferrulen i träs en rörliknande 24 pà ferrulerna. Det chassiemonterade kontaktdonet 20 är vidare försett med minst en làsklack 15 utförd med en vinklad greppyta 17, som kan samverka med en motriktad och likformig làsklack 14 pà kontaktdonet 21 genom att greppa och kvarhàlla kontaktdonets 21 làsklack 14 med sin vinklade greppyta 17.The casing 1 is also arranged to be able to enclose a ferrule for the optical fiber consisting of a more or otherwise attached, a coarser cylindrical part 5 in (I) in which the optical fiber is glued, clamped or otherwise fastened with its casing and a flange A coil spring 10 is arranged to act between the left end face 26 of the flange and an end face 9 of the chassis-mounted connector 20 for a contact area. A similar actuation of the ferrule against coil spring 23 acts on the ferrule 24. With the coil springs 8 a constant outwardly directed pressure on contact in and 23 the ferrules and can then be exerted. thus obtaining a good optical contact area in a manner treated between the ground and contacted interfaces 16 in the chassis-mounted connector 20 and in the connector 21. polished or otherwise For guiding the narrow cylindrical part 7 of the ferrule in the chassis-mounted connector 20 towards a narrow cylindrical part the connector 21, guide sleeve 10 on the abutting narrow parts 7 and 24 on the ferrule in wood a tube-like 24 on the ferrules. The chassis-mounted connector 20 is further provided with at least one locking lug 15 formed with an angled gripping surface 17, which can cooperate with an opposite and uniform locking lug 14 on the connector 21 by gripping and retaining the locking lug 14 of the connector 21 with its angled gripping surface 17.

Vid ditsättning av kontaktdonet 21 pà det chassiemonterade kontaktdonet 20, efter det att styrhylsan. 10 har satts pà ferruländarna med optofiber, trycks först kontaktdonet 21 mot det chassiemonterade kontaktdonet 20 till dess att en ändyta 18 pà kontaktdonet 21 när en ändyta 22 pà kontaktdonet 20 och optofiberändarna i kontakt med därefter vrids kontaktdonet 21 medurs tills det att Med làsklackarnas 14 och 15 vinklade styrhylsan 10 kommer i varandra, lásklackarna möts. greppytor motriktade och mittför varandra kommer efter frigörande av' kontaktdonet 21 fjäderkrafterna att föra de vinklade greppytorna i ingrepp med 'varandra och kontakten mellan ferruländarna kommer att bibehàllas. optofiberändarna i Vid borttagning av kontaktdonet 21 fràn det chassiemonterade kontaktdonet 20 trycks kontaktdonet 21 mot det 10 520 175 chassiemonterade kontaktdonet 20 till dess att ändytan 18 pà kontaktdonet 21 nàr ändytan 22 pà kontaktdonet 20 och greppytorna säras. Därefter vrids kontaktdonet 21 exempelvis 90 grader moturs sà att làsklacken 15 pà det chassiemonterade kontaktdonet 20 gàr fri fràn làsklacken 14 pà kontaktdonet 21. Därpà dras kontaktdonetj2l àt höger, vilket leder till att den optiska kontakten mellan optofiberändarna bryts i gränssnittet 16 och fjädertrycket i fjädrarna 8 och 23 pà ferrulerna minskar i det chassiemonterade kontaktdonet 20 och i kontaktdonet 21.When fitting the connector 21 on the chassis-mounted connector 20, after the guide sleeve. 10 has been placed on the ferrule ends with optical fiber, the connector 21 is first pressed against the chassis-mounted connector 20 until an end surface 18 of the connector 21 reaches an end surface 22 of the connector 20 and the optical fiber ends in contact therewith until the locking lugs 14 and The angled guide sleeve 10 comes into each other, the locking lugs meet. gripping surfaces opposite and opposite each other, after release of the connector 21, the spring forces will bring the angled gripping surfaces into engagement with each other and the contact between the ferrule ends will be maintained. When removing the connector 21 from the chassis-mounted connector 20, the connector 21 is pressed against the chassis-mounted connector 20 until the end surface 18 of the connector 21 reaches the end surface 22 of the connector 20 and the gripping surfaces. Thereafter, the connector 21 is rotated 90 degrees counterclockwise, for example, so that the locking lug 15 on the chassis-mounted connector 20 is released from the locking lug 14 on the connector 21. The connector is then pulled to the right, which causes the optical contact between the optical fiber ends and and 23 on the ferrules decreases in the chassis mounted connector 20 and in the connector 21.

Uppfinningen är naturligtvis inte begränsad till det ovan beskrivna och den pà ritningen visade utföringsformen, utan kan modifieras inom ramen för de bifogade patentkraven.The invention is of course not limited to the embodiment described above and the embodiment shown in the drawing, but can be modified within the scope of the appended claims.
