DESCRIPTION JPS61281487
[0001]
(A) Industrial Application Field The present invention relates to a speaker lead wire attaching
method for fixing a terminal board to a speaker and attaching a lead wire. (B) Prior art: FIG. 1
shows a conventional speaker terminal board, and FIG. 2 shows a conventional speaker provided
with a terminal board. In these figures, (upper) is a terminal board And a rectangular insulating
plate (2) and terminals (3) and (3) made of two metal materials arranged in parallel near both
ends of the insulating plate <2>. (4) is a rivet hole provided at the center of the insulating plate
(2), and the rivet hole (4) i: a connecting piece in which the terminal plate (1) is formed in the
frame (5) of the speaker It is riveted to (6). (7) (7) is a through hole formed by caulking
connection between the insulating plate (2) and the both terminals (3) and (3), and the lead wire
(8) from the drive portion (15) of the speaker ) Is inserted into the through holes (7) and (7) to
connect the terminals (3) and (3) with the solder. (9) (9) are connecting tongues provided at both
terminals (3) (3), and the acoustic signal line from the amplifier etc. is connected #I! ????
Such a terminal plate (upper) is, as shown in FIG. 2, such that the connection tongues (9) and (9)
of the terminals (3) and (3) project outward of the speaker. When the lead wire (8) is joined to
the terminal (3) of the terminal plate (upper) by soldering to the coupling piece (6), the end of
the lead wire (8) is passed through the through hole ( 7), and then interposing the shaping body
(10) between the lead wire (8), the frame (5) and the coupling piece (6), and the lead wire (8)
Pull. After defining the deflection of the lead wire (8) according to this, the lead wire (8) is joined
to the terminal (3) by soldering using the solder iron (11). After this, the above-mentioned
shaping body (10) is removed. (3) Problems to be Solved by the Invention As described above,
giving the lead wire (8) an appropriate amount of deflection means reducing the load on the lead
(8) to the vibration of the drive unit of the speaker as much as possible. So, although it is a very
important process for the speaker, the assembly operation of the speaker has been complicated
because of this. The present invention has been made in view of such circumstances, and

provides a speaker lead wire attaching method capable of easily giving an appropriate amount of
deflection to the lead wire from the drive unit of the speaker. (D) Means for Solving the Problems
The present invention relates to a lead wire coupling portion for coupling a lead wire from a
speaker to a terminal, a connection piece for connecting an external signal wire, and lead wire
coupling. A lead wire locking piece suspended from the joint portion from the head to the
speaker side through the constriction portion is provided, and the lead wire from the speaker is
connected to the lead wire bonding portion in a state of being locked by the lead wire locking
piece Afterward, the lead wire retaining piece is removed by cutting the constriction.
(E) The lead wire from the drive unit of the action speaker is given an appropriate deflection by
passing through the lead wire locking piece, and the load on the lead wire for the vibration of the
drive unit of the speaker is reduced. The present invention will be described with reference to
FIGS. 3 to 4. FIG. 3 is a perspective view of a terminal board according to an embodiment of the
present invention, and FIG. 4 is a side view showing an attached state of lead wires. In these
figures, (2) to (9) and (11) are the first rI! Fig. 7 shows the insulating plate to the connecting
tongue and the solder iron as in Fig. 2 and J. The terminal plate (upper) used in the present
invention is the 11th! The point different from the terminal plate (top) of I is that this terminal
(on the speaker side) is opposite to the connecting tongues (9) and (9) protruding from the
terminals (3) and (3) to the outside of the speaker. 3) The point is that the lead wire locking
pieces (13) and (13) extended from the (3) through the constricted portions (12) and (12) are
provided. The locking pieces (13) and (13) are suspended from the main body of the terminals
(3) and (3) at the constricted portion (12) (12> location), and the tips of the locking pieces (13
and 13) The part is provided with recesses (14) (14). As shown in FIG. 4, in the terminal plate (1
') of the above-mentioned structure, the connection tongue (9) of the end -I (3) protrudes
outward of the speaker, and the lead wire locking piece (13 ) Is coupled to the coupling piece (6)
of the frame (5) so that it hangs in the direction of the front of the speaker. When the lead wire
(8) from the drive unit (15) of the speaker is coupled to the terminal (3) of such a terminal plate
(upper), the end of the lead wire (8) is a terminal (3) and an insulating plate Insert the lead wire
(8) into the through hole (7) formed in the caulking part with (2), and then pull the lead wire (8)
appropriately to place the middle part of the lead wire (8) in the above-mentioned lead wire
locking piece With the solder irons held in the recess (14) of (13), the lead wire (8) is soldered to
the terminal (3). Thus, the lead wire (8) passes through the recess (14) of the lead wire locking
piece (13) to give an appropriate amount of deflection to the lead wire (8). Mounted on the top).
Thereafter, the lead wire locking piece (13) which has become unnecessary is cut off from the
narrow portion (12) by being folded upward from the narrow portion (12) and removed from the
terminal (3), This necking portion (12) may be cut using a cutting tool such as a nipper. ????
??????? Since (8) is attached to the terminal board (d) in a state where the deflection is
defined, load on the lead (8) against vibration of the drive unit (15) of the speaker can be
reduced, and the lead (8) Cutting accidents are prevented.

(G) As described in detail in the invention, according to the present invention, since the lead wire
locking piece for defining the deflection of the lead wire is provided in advance in the terminal
plate, the conventional shaping rod is separately prepared. In addition to the need for
preparation, the process of connecting lead wires and terminals can be simplified, and the
assembly process of such a speaker can be automated.
