ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a construction of processing an end portion of a shielded cable.
2. Description of the Related Art
As shown in
FIG. 14
, a shielded cable
60
comprises a conductor
61
, an insulating layer
62
formed on an outer peripheral surface of the conductor
61
, and a sheath layer
64
formed on an outer surface of the insulating layer
62
through a braid
63
. There has heretofore been proposed a connecting member
65
(see
FIG. 15
) to which the conductor
61
and the insulating layer
62
of the shielded cable
60
are adapted to be connected (Japanese Utility Model Unexamined Publication No. Hei. 5-15359).
The connecting member
65
includes an inner tubular connecting portion
66
, and an outer tubular connecting portion
67
provided in surrounding relation to the inner connecting portion
66
, the two connecting portions
66
and
67
being integrally connected together. The connecting member
65
is press-fitted on an end portion of a shielded cable
60
′, at which the insulating layer
62
is exposed, as shown in FIG.
16
(
a
), and the braid
63
and the sheath layer
62
are held between the inner and outer connecting portions
66
and
67
as shown in FIG.
16
(
b
), so that the shielded cable
60
′ and the connecting member
65
are connected together. Thereafter, the connecting member
65
is inserted into a connector housing (not shown), so that the braid
63
is connected to a contact (not shown) within the connector housing.
FIGS.
17
(
a
) and
17
(
b
) show another conventional construction using a sheath layer holder member
68
and a shield tube
69
(Japanese Patent Unexamined Publication No. Hei. 6-349532).
As shown in FIG.
17
(
a
), the sheath layer holder member
68
, made of an elastic, insulating material, is press-fitted on an end portion of a shielded cable
60
″ at which a braid
63
is exposed. A smaller-diameter portion
68
a
of the sheath layer holder member
68
is held in intimate contact with an insulating layer
62
, with the braid
63
turned over. At this time, part or the whole of the braid
63
is received in a larger-diameter portion
68
b
of the sheath layer holder member
68
.
In this condition, as shown in FIG.
17
(
b
), the shield tube
69
, made of metal, is applied to cover the sheath layer holder member
68
, and also the shield tube
69
is held in contact with the braid
63
. Then, the shielded cable
60
″ is inserted into a connector housing (not shown), and the shield tube is connected to a contact (not shown) provided in the connector housing. Reference numeral
68
c
designates a through-hole in the sheath layer holder member
68
.
However, the efficiency of insertion of the shielded cable
60
′ into the connecting member
65
, as well as the efficiency of insertion of the shielded cable
60
″ into the sheath layer holder member
68
and the shield tube
69
, is very poor. Besides, there is a fear that the size of the outer connecting portion
67
increases with the increase of the sheath layer
64
of the shielded cable
60
′. There has been encountered a further drawback that since the sheath layer holder member
68
and the shield tube
69
must be mounted on the shielded cable
60
″, the twofold time and labor have been required.
SUMMARY OF THE INVENTION
With the above problems in view, it is an object of this invention to provide a shielded cable end-processing construction in which the efficiency of a shielded cable end-processing operation is enhanced.
In order to achieve the above object, according to the invention, there is provided a shielded cable end-processing construction wherein a shielded cable includes an insulating layer formed on an outer peripheral surface of a conductor and a sheath layer formed on an outer surface of the insulating layer through a braid, a terminal is pressed to grip the conductor and the insulating layer of the shielded cable, thereby providing the terminal with the shielded cable, and the terminal with the shielded cable is inserted into a terminal receiving chamber in a housing body, and wherein one side wall of the housing body is notched to form an operation opening at the terminal receiving chamber, a braid contact member projects into the terminal receiving chamber from the operation opening, a size of the braid contact member being smaller than an outer diameter of the shielded cable, and when the terminal with the shielded cable is inserted into the terminal receiving chamber, the braid contact member is automatically inserted between the sheath layer and the insulating layer.
