Abstract

PURPOSE:To assure the wiring and at the same time to enhance the quality of a loud speaker system network without using the solder, by performing the connection by means of a calked terminal between the lead-out wires of a network circuit element incorporated into the speaker system or between the lead-out wire and an electric wire or the like. CONSTITUTION:For the assembly of a network of a loud speaker system, the coils 5 and 9 of the network circuit element are set previously on a network substrate 1 containing a substrate part 2, the printed circuit board parts 3 and 4, and the through hole parts of the parts 3 and 4. These coils 5 and 9 are wound and fixed by a band 12. In addition, the capacitors 6-8 and 12 plus a resistance 10 are added to the substrate 1. In this case, the lead-out wires 5'-11' of the circuit element and an electric wire, etc. are put through the through holes. Then a cylindrical calk terminal 14 put over the tips of the wires 5'-11' and 13, and the connection is secured by means of a claking tool. Then the attachment is assured for the wiring and the circuit element, and at the same time the assembling work is facilitated. Thus the quality is enhanced for a loud speaker system network.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a network incorporated into a speaker system. Conventional.

As the network mentioned above, resistors, capacitors, and
Network circuit elements such as coils are mounted, the lead wires of these circuit elements are inserted through small holes provided in the wiring board, led out to the copper foil side, and connected by soldering to the steel foil pattern. Ta. Another method is to implant lug terminals with multiple terminals on the board, and attach resistors to these terminals.
The lead wires of network circuit elements such as capacitors and coils were connected by soldering. However, in all of these conventional methods, the lead wires of the network circuit elements and the connections of the electric wires are soldered. Because of this, interconnections between wires are connected by solder, and dissimilar metals are interposed, which not only causes distortion and adversely affects the sound quality of the speaker, but also causes so-called tunnel soldering due to poor soldering, which can lead to quality defects. There was a flaw that caused it. In addition, in the former case, the connection of the lead wire must be made on the opposite side to the circuit element mounting surface, which is cumbersome, and in the latter case, the connection is made with a lug terminal, which results in a lack of stability.

The present invention aims to improve such drawbacks and, fourth, to provide a speaker system network with good workability.

An embodiment of the speaker system network of the present invention will be described below with reference to the drawings.

In Figures 1 to 3, (1) is a network board, and the board part (2) on which nine circuit elements are mounted, and the periphery (C, two sides in this example) of this board, are relative to the board part. Wiring board portions (3) and (4) having vertical rising portions are formed, and are integrally formed with a molding material such as phenol resin to have a U-shaped cross section. (to) this wiring board part (3

(B) is the lead wire, (10 is the lead wire of the resistor wire.) The above network circuit element is connected to the network board (1).
It is placed on the board section (2) or the wiring board sections (3) and (4) of. (to) are electric wires that are connected to the speaker unit or polyurethane, etc., and these electric wires are connected to the wiring board part (3), ( 4
)K is inserted into any through hole (2) formed in the network circuit element along with the lead wire of the network circuit element outward from the mounting direction of the network circuit element. α◆ is a cylindrical caulking terminal that connects the lead wires and electric wires of the above network circuit element by inserting them inward and tightening them. It appears that insertion and caulking will be performed.

Next, the assembly of the network configured in this way will be explained. The board part (21, wiring board part (
3), (4), and a network board (1) K with through holes (to) formed in the wiring board part, on which coils (r) and (9) of network circuit elements are placed as shown in the drawing, and the band ( 2) The wrapping is fixed. Also a capacitor (6),
Place (7), (8), (b) and resistance (to). At the same time as this placement, the portions for connecting and wiring the lead wires and electric wires of these network circuit elements to each other are inserted into appropriate through holes. At this time, the lead lines are directed outward from the network circuit element mounting portion. Next is the inserted leader line.

The tip of the electric wire, that is, the outside of the wiring board (3) is inserted so as to be covered with a cylindrical caulking end α◆, and the wire is caulked using a caulking tool. By doing this, the lead wires or electric wires can be easily connected to each other, and
Through this connection, circuit elements can also be attached. At this time, if the insulating coating is removed from the caulked portions of the lead wires and electric wires, or if a material with low electrical resistance such as copper is used for the caulked terminals, these wires can be interconnected. In addition, after caulking and connecting with caulking terminals, it is best to fix the network board and circuit elements to each other, or to the parts such as the network board and lead wires where they come into contact with each other with rubber adhesive, etc., without making chattering noises. It will be done.

As described above, in this invention, the network circuit elements are connected to each other or to electric wires by caulking terminals, so there is no need to use solder as in the conventional method.
Not only did the sound quality improve, but the wiring was done more reliably, resulting in a marked improvement in quality. In addition, since the wiring board is sandwiched between the mounting portion of the network circuit element and the caulking is performed on the outside, the circuit element can be fixed, and the workability is also improved. A network of speaker systems has been obtained that has the following effects.
