ABSTRACT:
TECHNICAL FIELD
The present invention relates to a vibrator holder for mounting a vibrator that vibrates a device body in an electronic device such as a communication terminal unit, and to a vibrator attaching method.
BACKGROUND ART
To a small-sized communication terminal unit, for example, a pager, a portable telephone, or the like, a vibrator is attached in order to inform a user of terminating call, by which the device body is vibrated. In this vibrator, an eccentric piece is attached to a drive shaft of a motor and vibration generated by rotating the eccentric piece by the drive shaft is transmitted to the device body.
Referring to
FIGS. 3 and 4
, examples of the conventional vibrator attaching structure will be described.
FIGS. 3A and 3B
show a first conventional example, in which in a state where a vibrator
50
is covered with a shock absorber
51
, this vibrator
50
is attached to holding portions
53
and
54
of a supporting member
52
, and then lead wires
55
extending from the vibrator
50
are soldered to a print circuit board
56
in which circuit parts are covered with a shield member
57
, whereby the vibrator
50
is electrically connected to the print circuit board
56
and thereafter the print circuit board
56
is attached to a case
58
or the supporting member
52
.
FIGS. 4A and 4B
show a second conventional example, in which a vibrator
60
is attached through a shock absorber
61
to a sub-print circuit board
62
with solder, and a male connector
63
a
of the sub-print circuit board
62
is put in to a female connector
63
b
of a main print circuit board
64
in which circuit parts are covered with a shield member
65
, whereby the vibrator
60
is electrically connected to the main print circuit board
64
and thereafter the main print circuit board
64
is attached to a case
67
. In this example, a shock absorber
66
is provided also between the vibrator
60
and the case
67
.
However, in case of the first conventional example shown in
FIG. 3
, the holding portions
53
,
54
for holding the vibrator
50
and the shock absorber
51
are constituted separately from the print circuit board
56
, and the holding force of the holding portions
53
,
54
in relation to the vibrator
50
and the shock absorber
51
is firmer than the connecting force between the print circuit board
56
and the lead wires
55
. For this reason, in case that the communication terminal unit is disassembled, in order to prevent the vibrator
50
from being connected by only the lead wires
56
and being in a hanging state, it must be disassembled after the solder of the lead wires
55
to the print circuit board
56
was removed, so that there was a problem that much time and labor require for the disassembly.
Further, the shield member
57
is provided above the print circuit board
56
, and vacancy is formed between the vibrator
50
and the print circuit board
56
and between the shield member
57
and the case
58
, whereby much arrangement space is required, so that there was a problem that the device must be made large.
Further, in case of the second conventional example shown in
FIG. 4
, the sub-print circuit board
62
for attaching the vibrator
60
and the shock absorber
61
thereto is required, and the connectors
63
a
,
63
b
must be arranged between the sub-print circuit board
62
and the main print circuit board
64
in order to electrically connect the vibrator
60
to the main print circuit board
64
. Further, the shield member
65
is provided above the main print circuit board
64
, and arrangement space for this shield member
65
and for vacancy between the shield member
65
and the sub-print circuit board
62
is required. Forth is reason, a height H from the main print circuit board
64
to the sub print circuit board
62
becomes relatively large, and the inner space of the case
67
becomes considerably wide. Therefore, there was a problem that the device must be made large similarly to in FIG.
3
.
The invention has been made in view of the above circumstances, and its object is to provide a vibrator holder and a vibrator attaching method, in which working efficiency at the assembly and disassembly time is good, and the required arrangement space is small thereby to make miniaturization of the device possible.
DISCLOSURE OF THE INVENTION
A vibrator holder according to the invention is characterized in that:
(1) There are provided a holding member for fitting and holding a vibrator therein, and a base member which, when attached onto a circuit board, forms a gap between it and the circuit board, the aforesaid holding member and base member are integrally formed, and the aforesaid vibrator is fitted into the afore said holding member, where by a terminal of this vibrator conducts to the aforesaid circuit board.
(2) The aforesaid base member is composed of a box-shaped member, and inner space of this box-shaped member forms the space between the base member and the aforesaid circuit board.
(3) The aforesaid base member is composed of a box-shaped member, and this box-shaped member is used also as a shield member of the aforesaid circuit board.
(4) A plate spring-shaped terminal is projectingly provided for the aforesaid vibrator, and a contact portion that comes into contact with and conducts to the terminal of the afore said vibrator is provided for the aforesaid circuit board.
A vibrator attaching method according to the invention is characterized:
(5) A vibrator attaching base is used, which is formed by integrally forming a holding member that holds a vibrator for vibrating a case and a base member attached onto a circuit board that conducts to a terminal of this vibrator, the vibrator is fitted into and held by the aforesaid holding member, and the aforesaid base member is attached to the aforesaid circuit board and forms vacancy between it and the circuit board.
(6) The aforesaid base member is composed of a box-shaped member, and this box-shaped member is used also as a shield member of the aforesaid circuit board.
(7) A plate spring-shaped terminal is projectingly provided for the aforesaid vibrator, and a contact portion is provided for the aforesaid circuit board thereby to come into contact with and conducts to the terminal of the afore said vibrator.
An electronic device according to the invention is equipped with:
(8) a vibrator holder in which there are provided a holding member for fitting and holding a vibrator therein, and a base member which, when attached onto a circuit board, forms a gap between it and this circuit board; the a fore said holding member and base member are integrally formed; and the a fore said vibrator is fitted into the aforesaid holding member, whereby a terminal of this vibrator conducts to the aforesaid circuit board.
A communication terminal unit according to the invention is equipped with:
(9) a vibrator holder in which there are provided a holding member for fitting and holding a vibrator therein, and a base member which, when attached onto a circuit board, forms a gap between it and this circuit board; the aforesaid holding member and base member are integrally formed; and the afore said vibrator is fitted into the aforesaid holding member, whereby a terminal of this vibrator conducts to the aforesaid circuit board.
As described above, the member in which the holding member and the base member are integrally formed is used as the vibrator attaching base for attaching the vibrator; the vibrator is fitted into and attached to the holding member, for example, by forcing the vibrator coated with a shock absorber into the holding member; and the base member is attached to the circuit board to cause the circuit board to conduct to the terminal of the vibrator, whereby an integral circuit board unit in which the vibrator is mounted on the circuit board is constituted. As described above, since the vibrator is held in the circuit board, efficiency of working such as assembly and disassembly at the manufacturing time and at the maintenance time is good, so that the vibrator can be readily attached
