Description

Title: Optical Fibre Connector DESCRIPTION This invention relates to an optical fibre connector.
A known conventional optical fibre connector is made integrally with an optical fibre embedded inside insulating plastic materials, resulting in it being difficult to check whether any disconnection of the optical fibre has occurred.
Further, the manufacture and assembly of such components is often difficult. In addition, known optical fibre connectors are relatively expensive due to their numerous components, and complicated manufacturing and assembly processes.
It is an object of the present invention to provide an optical fibre connector, which overcomes or at least alleviates the above-mentioned disadvantages. The optical fibre connector of the present invention comprises only a few components, is quick and easy to assemble, and may be used with various optical fibres of any diameter.
Accordingly, the present invention provides an optical fibre connector comprising a connecting head having a chamber in a rear portion thereof, an inserting connect member fitted in said connecting head, wherein said connecting head has two opposite insert holes provided in two opposite side walls of said chamber of said connecting head, and said inserting connect member having its intermediate portion forming a connect portion provided with two elastic insert blocks corresponding to the insert holes of the chamber of the connecting head.
In a preferred embodiment, the connecting head has a step-shaped intermediate hollow. Preferably, the connecting head also comprises a neck member having an inner conical passageway, the front end of the chamber of the connecting head being connected with the neck member. It is preferable that a front portion of the neck member is connected with a tapered tube.
It is preferred that the inserting connect member has a passageway of a stepped shape formed in its interior, and it is preferable that a front portion of the inserting connect member is gradually shrunk in a stepped shape. Preferably, the inserting connect member has a stop rim in the inner wall of a rear portion of the passageway of the inserting connect member.
It is preferred that the connect portion of the inserting connect member has a tapered tube projecting from a front end thereof, and further, it is preferable that the tapered tube has a plurality of lengthwise slots spaced apart to shrink elastically.
In this way, an optical fibre is threaded through the inserting connect member, then the inserting connect member is engaged with the connecting head.
Lastly, the core of the optical fibre is threaded out of the tube of the inserting connect member, thus finishing the assembly of the optical fibre connector.
The invention will be better understood by referring to the accompanying drawings wherein: Figure 1 is an exploded perspective view of a known conventional optical fibre connector; Figure 2 is an exploded perspective view of an optical fibre connector in accordance with the present invention ; and Figure 3 is a side cross-sectional view of the optical fibre connector in accordance with the present invention.
As shown in Figure 1 of the drawings, a known optical fibre connector comprises a sleeve 11, an engaging member 12, a connecting member 13, a tube 14 and a protective ring 5 as main components.
The sleeve 11 has a central hollow passageway 110 therethrough and a passage hole 111 in its wall. In use, the engaging member 12 is fitted into the passageway 110 of the sleeve, having a lengthwise channel 120 inside and a projection 121 on an upper side. The connecting member 13 is inserted into the engaging member 12, having a small diameter tube 130 formed in a front portion with a fibre tube 131 extending forward out of the lengthwise channel 120 of the engaging member 12. Then, the tube 14 is fitted in the rear portion of the connecting member 13 to push it into the engaging member 12 and fix it therein.
In order to assemble the known connector, the optical fibre is threaded through the tube 14 and the connecting member 13, pushing the front end of the outer layer 40 of the optical fibre 4 through the tube 14 and into the connecting member 13. At the same time, an intermediate covered layer 41 is also fitted inside the small diameter tube 130 of the connecting member 13, thus permitting the fibre thread 42 to locate in the fibre tube 131 of the connecting member 13. Lastly, the protective ring 5 is fitted around the passage hole 111 of the sleeve 11, thus completing the assembly of the known optical fibre connector.
Figure 2 shows an embodiment of an optical fibre connector in accordance with the present invention, comprising a connecting head 2 and an inserting connecting member 3 as main components combined together. The connecting head 2 is provided in a rear portion with a chamber 20 having insert holes 200 in two opposite side walls, and its front portion connected with a neck member 21 forming a conical channel. The front end of the neck member 21 is connected with a fibre tube 22 with a smaller diameter than that of the neck member 21, forming a stepped passageway gradually shrunk outward for the core 42 of the optical fibre to thread through.
Then, the inserting connecting member 3 is connected to the connecting head 2, having a stepped, gradually shrunk passageway 30 in a center hollow and a stop rim 300 disposed inside at a proper position for stopping the front end of the outer layer 40 of the optical fibre 4. Further, the inserting connecting member 3 is provided with an annular groove 31 in an outer surface, a connecting portion formed in an intermediate portion and having two opposite elastic projections 320 corresponding to the engagement holes 200 of the chamber 20 of the connecting head 2, and a tapered tube 33 protruding out of the front end of the connecting portion 32 and having a plurality of lengthwise slots 330 spaced apart to elastically shrink and then tightly clamp the intermediate covered layer 41 of the optical fibre 4 after the intermediate layer 41 threads through therein.
In assembling and using, as shown in Figure 2 and 3, firstly, thread the optical fibre 4 through the passageway 30 in the inserting connect member 3 and push the front end of the outer layer 40 of the optical fibre 4 forward to touch the stop rim 300 of the inserting connect member 3 and synchronously the intermediate layer 41 of the optical fibre 4 fitted into the tapered tube 33 of the inserting connect member 3.
Then the tapered tube 33 of the inserting connect member 3 is directly inserted in the chamber 20 of the connect head 2, and pushed forward to let the two elastic projections 320 of the connect portion 32 respectively engaged with the insert holes 200 of the chamber 20 of the connect head 2, thus, the inserting connect member 3 and the connect head 2 tightly connected by means of mutual engagement In addition, after the tapered tube 33 of the inserting connect member 3 is inserted in the tapered neck member 21, it is forced to elastically shrink by a comparatively small inner diameter of the tapered neck member 21, accordingly letting the optical fibre 4 positioned stably therein, with its core 42 extending out of the tube 22 of the connect head 2, finishing the assembly of a optical fibre connector ready for use.
Compared with the known conventional optical fibre connectors, this invention has the following advantages: 1. There are fewer components needed for making up an optical fibre connector, and it can be assembled with quickness and convenience, enhancing assembly efficiency.
2. Components can be manufactured easier, reducing their costs.
3. The assembly of the components is stable, increasing stability for connecting or inserting an optical fibre.
4. It is applicable to various optical fibres of any diameter, and further, it is convenient to replacing new optical fibres.
While the preferred embodiment of the invention has been described above, it will be recognised and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
