ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an adapter, and more particularly to a an adapter for an optical fiber cable, wherein each of the optical fiber cables with connectors can be removed from the respective connecting tube easily and rapidly for replacement, thereby shortening the testing time, and thereby enhancing the testing efficiency.
2. Description of the Related Art
A conventional adapter
7
for an optical fiber cable in accordance with the prior art shown in
FIG. 13
comprises a first connecting member
71
having a plane
711
and a positioning sleeve
712
inserted into the plane
711
, a second connecting member
72
having a plane
72
rested on the plane
711
of the first connecting member
71
and a positioning sleeve
722
inserted into the plane
721
, and a connecting tube
73
having a first end
731
inserted into the positioning sleeve
712
of the first connecting member
71
and a second end
732
inserted into the positioning sleeve
722
of the second connecting member
72
.
However, the positioning sleeve
712
is inserted into the plane
711
of the first connecting member
71
to combine with the first connecting member
71
, and the positioning sleeve
722
is inserted into the plane
721
of the second connecting member
72
to combine with the second connecting member
72
, so that the two positioning sleeves
712
and
722
are not aligned with each other easily, thereby increasing difficulty in the working process and decreasing the precision of the products. In addition, the optical fiber cable cannot be mounted on and removed from the conventional connector
7
easily and rapidly for replacement, thereby increasing the testing time and decreasing the testing efficiency.
Another conventional adapter for an optical fiber cable in accordance with the prior art shown in
FIG. 14
comprises two connecting members
71
A each having a plane
711
A and a positioning sleeve
712
A inserted into the plane
711
A, and a connecting tube
74
A having two ends each inserted into the positioning sleeve
712
A of the respective connecting member
71
A.
However, the positioning sleeve
712
A is inserted into the plane
711
A of the connecting member
71
A to combine with the connecting member
71
A, so that the two positioning sleeves
712
A are not aligned with each other easily, thereby increasing difficulty in the working process and decreasing the precision of the products. In addition, the optical fiber cable cannot be mounted on and removed from the conventional connector easily and rapidly for replacement, thereby increasing the testing time and decreasing the testing efficiency.
Another conventional adapter
8
for an optical fiber cable in accordance with the prior art shown in
FIGS. 15 and 16
comprises a connecting seat
81
formed with an insertion hole
812
and an inner thread
811
, a connecting sleeve
82
mounted on the connecting seat
81
and formed with an insertion hole
822
and having an outer thread
821
screwed into the inner thread
811
of the connecting seat
81
, and a connecting tube
83
having two ends inserted into the insertion hole
812
of the connecting seat
81
and the insertion hole
822
of the connecting sleeve
82
respectively.
However, the insertion hole
812
of the connecting seat
81
and the insertion hole
822
of the connecting sleeve
82
are not aligned with each other easily, thereby increasing difficulty in the working process and decreasing the precision of the products. In addition, the optical fiber cable cannot be mounted on and removed from the conventional connector
8
easily and rapidly for replacement, thereby increasing the testing time and decreasing the testing efficiency.
Another conventional adapter
9
for an optical fiber cable in accordance with the prior art shown in
FIG. 17
comprises a connecting seat
91
having a center formed with a connecting hole
913
having a first end formed with a first inserted hole
911
having an end face formed with a first inner thread
9111
and a second end formed with a second insertion hole
912
having an end face formed with a second inner thread
9121
, a first connecting sleeve
93
having an outer wall formed with an outer thread
933
screwed into the first inner thread
9111
of the connecting seat
91
and an inner wall formed a first receiving hole
931

SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an adapter for an optical fiber cable.
Another objective of the present invention is to provide an adapter, wherein by connection of the quick connector and the insertion posts of the connecting member, each of the optical fiber cables is connected to the testing instrument stably and efficiently, thereby facilitating the testing instrument performing the relevant testing procedures.
A further objective of the present invention is to provide an adapter, wherein each of the optical fiber cables can be mounted an and removed from the second insertion hole of a respective one of the connecting tubes easily and rapidly for facilitating replacement, thereby shortening the testing time, and thereby enhancing the testing efficiency.
In accordance with the present invention, there is provided an adapter, comprising:
an insertion terminal having a first side formed with an insertion end and a second side formed with a receiving space connecting to the insertion end;
a connecting member mounted on the insertion terminal and including a quick connector inserted into the receiving space of the insertion terminal, and a plurality of insertion posts each having a first end connected to a distal end of the quick connector;
a plurality of connecting tubes each having a first end mounted on a second end of a respective one of the insertion posts of the connecting member; and
a plurality of optical fiber cables each having an end mounted on a second end of a respective one of the connecting tubes and each contacting with the second end of a respective one of the insertion posts of the connecting member.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
