Abstract
The invention relates to an optical fiber connector comprising a casing and a contact pin component spliced in the casing; the contact pin component includes a flange which is matched with a positioning interface arranged inside the casing; the positioning interface in the casing is a ring surface; swirl reducing grooves are uniformly formed on the periphery of the flange; swirl reducing bonds extending from the ring surface to the rear end of the casing in the axial direction of the flange are arranged in the casing; the number of the swirl reducing bonds is less than that of the swirl reducing grooves; the peripheral angle formed by each two adjacent swirl reducing bonds is an integral multiple of the peripheral angle formed by each two adjacent swirl reducing grooves; and the swirl reducing bonds are matched with the swirl reducing grooves. The optical fiber connector which adopts the technical scheme is characterized in that the swirl reducing bonds are arranged corresponding to the positions of the swirl reducing grooves formed on the flange in the casing, and serve as a strengthening rib in the casing, thereby intensifying the strength of the casing.
Description
Technical field
The present invention relates to a kind of joints of optical fibre.
Background technology
The joints of optical fibre are an element of any optical fiber telecommunications system substantially.For example, this connector can be used for segmentation optical fiber to connect into longer length; Optical fiber is linked to the active device such as radiation source detecting device and repeater; Or optical fiber is linked to the passive device such as switch and attenuator.The major function of joints of optical fibre is to safeguard that two optical fiber end are axially alignd a fiber cores with another fibre core; Thereby the light from an optical fiber is all coupled to another optical fiber.This needs a quite accurate connection, because optical fiber Zai Guang district (fibre core) is quite little.In single-mode fiber, core diameter is about 8 μ m (1 μ m=10
-3mm).US Patent No. 6287018 has been announced a kind of like this joints of optical fibre: in the housing of these joints of optical fibre, be fitted with a contact pin component, contact pin component comprises ring flange and is plugged in the contact pin of ring flange front end, wherein the outer peripheral face of ring flange is provided with positive six ribs and only revolves structure, and in housing, positive six ribs of companion flange dish only revolve structure and are provided with orthohexagonal hole.Although use the structure of positive six ribs can prevent that contact pin component from rotating with respect to housing; protection optical cable is avoided reversing and is damaged; but; in housing, arrange behind orthohexagonal hole; the shell wall of housing is by skiving; because the joints of optical fibre are generally all smaller, the attenuate small to shell wall all can reduce the intensity of housing greatly again.In addition, this United States Patent (USP) also provides a kind of contact pin component to be provided with a plurality of slits, and housing is provided with a plurality of projections, in the less housing of the joints of optical fibre, a plurality of projections is set, when injection moulding, be difficult for the demoulding, easily cause projection situation relative and that housing generation is torn when the demoulding to occur.
Summary of the invention
The object of this invention is to provide a kind of joints of optical fibre, little and be difficult for the problem of the demoulding in order to solve the casing rigidity of existing fiber connector.
For achieving the above object, the present invention adopts following technical scheme: a kind of joints of optical fibre, comprise housing and be plugged in the contact pin component in housing, interface, location in described housing is an anchor ring, upwards evenly be provided with only spin slot the week of ring flange, in housing, be provided with from anchor ring, along ring flange, axially to housing rear end, extend only revolve key, the number of only revolving key is less than the only number of spin slot, and every two adjacent circumferential angles of only revolving key are every two adjacent only integral multiples of the circumferential angle of spin slot, and the described key that only revolves coordinates with only spin slot is identical.
Upwards evenly be provided with two, four or six only spin slots described ring flange week, in described housing, upwards being evenly provided with one, two or three only revolves key week, and the present invention adopts four to stop spin slot and two and only revolve key.
The joints of optical fibre of such scheme, in its housing, corresponding to the only spin slot position arranging on ring flange, be provided with and only revolve key, only revolve key and in housing, played the effect of reinforcement, strengthened the intensity of housing, and in the situation that meeting intensity, realized the reliable demoulding.In addition, only revolve key together with stopping spin slot inserting, played the effect that prevents that contact pin component from rotating with respect to housing, avoided rotating and causing optical cable to turn round the situation generation that the even whole optical cable of damage fractures relative to housing because of contact pin component.
In addition, housing is interior along circumferentially being evenly provided with two only revolves key altogether, only revolve key and be uniformly distributed and can make housing upwards there is better mechanical property in week, avoided arranging that inhomogeneous to produce circumferential shrinkage factor otherness while causing injection moulding large, the problem that product percent of pass is low because only revolving key.Also have, being upwards evenly provided with four only spin slots the week of ring flange, stop spin slot and only revolve the corresponding cooperation of key, on symmetrical position, arrange when four only spin slot makes to complete anti-rotating function and there is again good mechanical property.Also have, in housing, along being circumferentially evenly provided with two, only revolve key, four only spin slots are upwards evenly being set in the week of ring flange, only contact pin component rotation can, by the identical inserting of contact pin component in housing, need be convenient to fast accurate assembling less than the angle of 90 ° when mounted.

Embodiment
A kind of joints of optical fibre of the present invention shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, comprise housing, housing is pegged graft and is formed by procapsid 2 and back casing 5, in procapsid, only revolve and be fitted with contact pin component, procapsid 2 and back casing 5 plug-in position places are provided with a spring fitting chamber, spring fitting is indoor is provided with spring 4 along this joints of optical fibre plug direction, and one end of spring 4 is applied on back casing 5, and the other end of spring 4 is applied on contact pin component.Above-mentioned contact pin component comprises that ring flange 3 and interference are plugged in the contact pin 1 of ring flange 3 front ends, the front end face of ring flange 3 is plane, upwards evenly have four the week of ring flange 3 from ring flange front end face along the axially extended only spin slot 8 of contact pin component, front end face with respect to ring flange 3 in procapsid 2 is provided with thrust surface 11, in housing, be provided with two from thrust surface 11, extend back only revolve key 7, only revolve the key 7 only spin slot 8 symmetrical with on ring flange two and coincide and coordinate.Afterbody at back casing 5 is provided with a sheath 9, and the afterbody outer peripheral face of sheath 9 is provided with dislocation preventing slot 10.
For example, on ring flange, be evenly provided with 6 only during spin slot, in procapsid, can arrange 1,2,3,4 or 5 and only revolve key, the key mapping of every kind of situation can select with 6 only 1,2,3,4 or 5 in spin slot combine.
