ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a coaxial cable connector and a method for assembling the same connector and in particular to a technique for improving in particular the workability in soldering a core wire at the time of assembly.
A related coaxial cable connector will be explained with reference to
FIGS. 6 and 7
. In the construction of a coaxial cable connector shown in
FIG. 6
, a terminal
72
is provided at a leading end of a terminal holder
71
formed from an insulating material, and with one of two-part lids
73
being closed which are provided at the leading end of the holder
71
in such a manner as to be opened and/or closed via an integral hinge or the like, a shield cover
74
is attached to the external circumference of the holder
71
, the shield cover
74
being constructed so as to extend as far as a leading end a coaxial cable
50
in such a manner as to cover the outer circumference of the one of the lids
73
which is closed.
A method for assembling the connector constructed as described above to the coaxial cable
50
comprises, as shown in
FIG. 6
, the steps of allowing a core wire
52
of the coaxial cable
50
to pass through a connecting hole
72
a
formed in a vertical wall at the leading end of the terminal
72
, applying a soldering iron
60
to this portion for soldering, thereafter closing the other lid
73
, introducing a sleeve
79
over the outer circumference of the holder
71
as shown in
FIG. 7
, and a clamping members
79
a
at a leading end of the sleeve
79
are clamped to secure the sleeve
79
with the coaxial cable
50
for completion of the assembly.
With the coaxial cable connector constructed as described above, however, since soldering has to be carried out with respect to the surface extending vertically, it is difficult to apply the soldering iron to the proper position needing soldering, and in addition, it is also difficult to secure a leading end of the soldering iron
60
during the soldering. Thus, there is caused a problem that the workability in soldering tend to be reduced.
In addition, in a case where fused solder is sagged on the insulator (the lid
73
or the like) to thereby open a hole in the insulator, there is caused a concern of short circuit when a bent portion is provided to the core wire
52
as shown in FIG.
1
.
SUMMARY OF THE INVENTION
The present invention was made in view of the aforesaid problems and an object thereof is to provide a coaxial cable connector which can improve the workability in soldering by making it possible for the leading end of the soldering iron to be stably fixed to a soldering surface at the time of soldering and which is free from a risk of sagging of fused solder and a method for assembling the same connector to a coaxial cable.
In order to achieve the above object, there is provided a connector for a coaxial cable comprising:
a terminal including:
a connecting portion having a through hole to which a core wire of the coaxial cable is inserted to be electrically connected therewith; and
a flat projection formed in the vicinity of the through hole on the connecting portion; and
a terminal holder made of an insulating material for accommodating the terminal.
Preferably, the connecting portion is formed as a vertical wall member extending perpendicular to an insertion direction of the coaxial cable, and the flat projection includes a horizontal table member projected therefrom so as to extend parallel with the insertion direction of the coaxial cable.
According to the above configuration, soldering can be carried out with the leading end of the soldering iron being stably supported on the horizontal table member and the workability in soldering can be improved, thereby making it possible to perform soldering work quickly and with high quality. In addition, since fused solder is received by the horizontal table member, sagging of fused solder can be prevented, whereby a risk of generation of short circuit can be prevented.
Preferably, the terminal holder includes a lid body for opening/closing a space where the connecting portion is located. A soldering iron is inserted into the space formed by opening the lid body to solder the connecting portion and the core wire.
According to the above configuration, the soldering iron for performing soldering work is placed on the horizontal table member through the space opened by the lid body, whereby the workability in soldering can be improved.
Preferably, a part of the vertical wall member is cut and erected to form the horizontal table member. The terminal holder has a projection on an inner wall thereof, which is engaged with an opening formed on the connecting portion due to the formation of the horizontal table member.
According to the above configuration, there is no need to provide a separate table member for assembly, a construction being thus provided which is simple and free from wastefulness.
Preferably, a corner portion defined by the vertical wall member and the horizontal table portion is utilized for a portion where a leading end of a soldering iron for soldering the connecting portion and the core wire is abutted.
According to the above configuration, since soldering work can be performed with the leading end of the soldering iron being supported on the table portion, the workability in soldering can be improved and soldering work can be carried out quickly and with high quality.
