ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an electronic equipment terminal connector, electronic equipment, and electronic equipment terminal connector unit suitable for electric tuners used in television receivers, VCRs, satellite broadcasting receivers, and other electronic devices.
BACKGROUND OF THE INVENTION
Electric tuners used for television receivers, VCRs, satellite broadcasting receivers, and other electronic devices are one example of electronic equipment which is provided with an electronic equipment terminal connector in which a plurality of terminal pins are linked to one another by an insulator.
To bring the electric tuner in actual operation, it is required to externally supply a voltage for driving amplifier circuits, local oscillator circuits, and frequency converter circuits in the electric tuner, and also a synchronize voltage for synchronizing band-pass filters of input circuits and inter-stage circuits, and PLL control data when making the synchronization by PLL.
For such a purpose, the electric tuner employs a connection terminal for the external connection. As such a connection terminal, feed-through capacitors and terminal pins have been known conventionally.

As shown in FIG.
8
(
a
) and FIG.
8
(
b
), the electric tuner has an arrangement in which a plurality of feed-through capacitors
121
are provided on one of the side surfaces of a chassis angle
122
, and an antenna input terminal
123
and antenna output terminal
124
are provided on another side surface of the chassis angle
122
, i.e., the surface perpendicular to the surface on which the feed-through capacitors
121
are provided, and an upper shield cover
125
and lower shield cover
126
are provided on upper and lower surfaces of the chassis angle
122
.
In this electric tuner, the plurality of feed-through capacitors
121
are fixed on the chassis angle
122
by solder. In the chassis angle
122
, the terminal sections (not shown) of the feed-through capacitors
121
are connected to a print substrate (not shown).

9
(

) is a front view of the electric tuner and FIG.
9
(

(

In this electric tuner, instead of the feed-through capacitors
121
as shown in FIG.
8
(
a
) and FIG.
8
(
b
), a plurality of terminal pins
128
are directly inserted and solder fixed on a print substrate
127
provided in the chassis angle
122
.
The electric tuner employing feed-through capacitors as the connection terminal has drawbacks that it is more expensive than the electric tuner employing the terminal pins and it takes more time to make connections.
Meanwhile, in the electric tuner in which terminal pins as the connection terminal are directly fixed on the print substrate, because individual pins are merely soldered directly on the print substrate, the terminal pins tend to come off easily and the problem of weak terminal portion is presented.
In order to increase the strength of the terminal portion, there has been proposed an electronic equipment terminal connector
130
as shown in FIG.
10
(
a
) through FIG.
10
(
e
) for connecting an external power source, etc., and electronic equipment, in which FIG.
10
(
a
) is a front view, FIG.
10
(
b
) is a plan view, FIG.
10
(
c
) is a bottom view, FIG.
19
(
d
) is a left side view, and FIG.
10
(
e
) is a right side view.
The terminal connector
130
has an arrangement in which a plurality of terminal pins
131
are linked to one another in a straight line by an insulator
132
of a rectangular shape. Such a terminal connector is disclosed as a capacitor array, for example, in Japanese Unexamined Patent publication No. 153596/1990 (Tokukaihei 2-153596) (Published Date: Jun. 13, 1990).
FIG.
11
(
a
) and FIG.
11
(
b
) show an electric tuner to which the terminal connector
130
having the above arrangement is attached, in which FIG.
11
(
a
) is a front view and FIG.
11
(
b
) is a plan view.
As shown in FIG.
11
(
a
), the terminal connector
130
is arranged such that the insulator
132
is fixed on the chassis angle
122
by a fixing tongue
141
. Here, as shown in
FIG. 12
, the terminal pins
131
are connected to the print substrate
127
in the chassis angle
122
.
FIG. 12
shows a main portion of the cross sectional view of FIG.

(

) taken along the line X—X.
The following describes how the electric tuner employing the terminal connector
130
is assembled, referring to FIGS.
11
(
a
) and (
b
) and FIG.
12
.
1. The antenna input terminal
123
and antenna output terminal
124
are fixed on the chassis angle
122
by bezel or solder.
2. The terminal connector
130
is attached to the chassis angle
122
.
3. The print substrate
127
mounting chip components and insertion parts is fixed in position in the chassis angle
122
.
4. The print substrate
127
and chassis angle
122
, the print substrate
127
and terminal pins
131
of terminal connector
130
, and the print substrate
127
and antenna input terminal
123
and antenna output terminal
124
are each soldered with one another by reflow or flow.
5. After adjustment, the upper shield cover
125
and lower shield cover
126
are attached to the chassis angle
122
.
However, in the electronic equipment employing the electronic equipment terminal connector
130
as shown in FIG.
10
(
a
) through FIG.
10
(
e
), i.e., in the electric tuner as shown in FIGS.
11
(
a
) and (
b
) and
FIG. 12
, when the terminal connector
130
is to be attached to the chassis angle
122
, the fixing tongue
141
as shown in FIGS.
11
(
a
) and (
b
) and
FIG. 12
is provided at the edge portion of the opening section
122
a
on a side surface of the chassis angle
122
through which the terminal connector
130
is to be inserted, and the insulator
132
of the terminal connector
130
is fixed on the chassis angle
122
by bending the fixing tongue
141
.
Therefore, a step of bending the fixing tongue
141
is required in the process of attaching the terminal connector
130
to the chassis angle
122
, thus making the process complex and operability suffers.

The present invention was made to solve the foregoing problems, and it is an object of the present invention to provide an electronic equipment terminal connector, electronic equipment, and electronic equipment terminal connector unit, by which an electronic equipment terminal connector in which a plurality of terminal pins are linked to one another by an insulator can be fixed easily on an electronic equipment chassis (chassis angle) only by inserting the electronic equipment terminal connector into an opening section of the electronic equipment chassis when making attachment.
In order to achieve the foregoing object, an electronic equipment terminal connector of the present invention is to be attached to an electronic equipment chassis by inserting a portion of an insulator composed of a plurality of terminal pins linked to one another into an opening section of the electronic equipment chassis so as to make an electrical connection between the terminal pins and a substrate portion in the electronic equipment chassis, and the electronic equipment terminal connector is provided with a stop section which stops the insulator on the electronic equipment chassis while the portion of the insulator is inserted into the opening section of the electronic equipment chassis.
With this arrangement, the electronic equipment terminal connector can be attached to the electronic equipment chassis only by inserting a portion of the insulator of the electronic equipment terminal connector into the opening section of the electronic equipment chassis. Thus, it is not required to provide a conventionally
