ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an optical fiber connecter, particularly to one consisting of a connect head and an inserting connect member, only a few components, assembled with q quickness and applicable to various optical fiber of any diameters.
2. Description of the Prior Art
A known conventional optical fiber connecter is mostly made integral with an optical fiber embedded inside insulating plastic materials, resulting in much inconvenience for checking in case any disconnection of the optical fiber should occur. Besides, manufacture and assembly of such components is by no means easy.
Another known conventional optical fiber connecter has come into existence. As shown in
FIG. 1
, it includes a sleeve
11
, an engaging member
12
, a connect member
13
, a tube
14
and a protective ring
5
as main components.
The sleeve
11
has a center hollow passageway
110
and a passage hole
111
in its wall. The engaging member
12
is to be fitted in the passageway
110
of the sleeve
11
, having a lengthwise channel
120
inside and a projection
121
on an upper side. The connect member
13
is to be inserted in the engaging member
12
, having a small diameter tube
130
formed in a front portion with a fiber 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 connect member
13
to push it move into the engaging member
12
and fixed therein.
In assembling, firstly, thread the optical fiber
4
through the tube
14
and the connect member
13
, pushing the front end of outer layer
40
of the optical fiber
4
move through the tube
14
and into the connect member
13
. At the same time, an intermediate covered layer
41
is also fitted in the small diameter tube
130
of the connect member
13
, thus permitting the fiber
42
thread out of the fiber tube
131
of the connect member
13
. Lastly, fit the protective ring
15
around the passage hole
111
of the sleeve
11
, thus finishing assembly of the conventional optical fiber connecter.
As can be noted from the above description, the known conventional optical fiber connecter can hardly be made with low cost due to its numerous components, complicated manufacturing processes as well as assembly, resulting in high cost.
SUMMARY OF THE INVENTION
The objective of the invention is to offer an optical fiber connecter with only a few components, quick in assembling and applicable to various optical fibers of any diameters.
The feature of the invention is two opposite insert holes provided in two opposite side-walls of a chamber formed in a connect head, a stop rim disposed on an inner wall of a larger diameter portion of a passageway of an inserting connect member, which has its front portion shrunk in a tapered shape toward the connect head and its intermediate portion forming a connect portion provided with two elastic insert blocks corresponding to the insert holes of the chamber of the connect head and a tapered tube protruding out of the front end of the connect portion. Besides, the tapered tube has plural lengthwise slots spaced apart to shrink elastically.
