接続させる方法である。Conventional technology A parallel multi-core flat cable is inserted into a printed circuit board,
As a method to connect the lead core wire to the circuit of the board,
Conventionally, two methods have been used. One of them is, as shown in FIG. 4, the terminal coating of the flat cable 1 is exposed, and the lead core wire 2 is exposed at the tip.
is manually aligned and inserted into the lead insertion hole 3a of the printed circuit board 3, and the protruding portion toward the back side of the circuit board is connected to the land 4a of the pattern 4 by soldering. The other method uses a board-in-type cable connector, and inserts the lead core wire exposed at the end of the flat cable into the terminal hole of the connector, connects it to a metal terminal by crimping, etc. inside the cable, and then connects it to the metal terminal. Insert the connecting pin of the connector integrated at the tip directly into the insertion hole of the printed circuit board with or without a socket, solder it to the land of the pattern on the back side, and connect the flat cable through the connecting pin of the connector. This is a method of connecting to a circuit on a printed circuit board.

作業が上述した場合に比べてさらにしにくくなり、作業
性を著しく損なう問題が生ずる。Problems to be Solved by the Invention However, the first method described above connects the lead core wires 2 exposed at the terminals of the flat cable 1 to the printed circuit board 3.
The insertion hole 3a has a very narrow pitch interval.Since the insertion hole 3a is inserted directly into the fist by manual alignment, the operator needs considerable skill to insert it reliably, and there are many cases of incorrect insertion. , insertion work takes time and workability is extremely poor. Moreover, since it is in a state where it can move freely when inserted into the lead core wire 2, when it is soldered in the subsequent soldering process, the lead core wire 2 and
... will rise, reducing the reliability of soldering. Therefore, there is a problem in that a labor-intensive post-processing is required after the solder tipping, and that the correction work takes time. Therefore, in order to prevent the solder from floating during solder dipping, the lead core wires 2.2 at both ends are kinked as shown in FIG.
After being inserted into the insertion holes 3a, . . . . . . . . . However, when kink processing is performed in this manner, it becomes even more difficult to insert the insert into the insertion hole 3as-/fist than in the case described above, resulting in the problem of significantly impairing workability.

夕を一体的に組付ける作業工程を経なければならない。On the other hand, according to the second method described above, since the connection pin is inserted into the insertion hole of the board through a relatively rigid connection pin, the workability of the insertion work is good, and there is no floating of the lead, making it reliable. This has the advantage of allowing easy insertion connections. but,
On the other hand, this method involves inserting the lead core wire exposed at the cable end into the terminal hole of the connector, crimping it to the metal terminal, and then
A caulking process is required, and a process of integrally assembling the connector to the cable terminal must be performed.
したがって、作業工程上、コスト高につく欠点がある。Therefore, there is a drawback in terms of the work process, which is high cost.

The end portion of this multicore cable 100 has been subjected to the above-described terminal processing in advance. In this terminal processing, the coating 102 at the tip of the cable is first stripped to a predetermined length Ll, and then the excess portion of the exposed coating is cut and removed, resulting in a portion of the coating 102 as shown in FIG. , a length Ll is left at the tip of the terminal portion. As a result, an exposed portion 104 of the lead core wire 101 is formed with a length L behind the terminal coating 103 left at the tip.
Formed by 3. After the terminal is processed in this way, the terminal is guided and inserted into the opening 22 of the socket 20. By inserting the cable tip, as shown in FIG. 3(b), when the tip end surface of the terminal sheath 103 comes into contact with the inner bottom surface of the opening 22, the end sheath 103 is held at the abutting position. Furthermore, when the cable terminal part is inserted into the opening 22, the cable main body part 102 behind it is pushed into the opening 22 as shown in FIG. Being forced into it.

できる。After the terminal portion of the multicore cable 100 is inserted and temporarily fixed into the insertion position of the printed circuit board 10 via the socket 20, the printed circuit board 10 is then subjected to a soldering dip process. In this solder dipping step, the lead core wires 101 protruding from the back surface of the printed circuit board 10 are soldered to the lands 13 of the circuit pattern 12 together with the leads of other components as shown in FIG. 3(E). At that time, multi-core cable 100
Since the terminal covering portion 102 of the lead wire 102 is prevented from coming out by the claw pieces 23 and 23 within the opening 22, the lead core wires 101... are not lifted up or pulled out from the board by the force of the molten solder, as in the conventional case. This phenomenon disappears, and it is possible to perform good solder dipping with a protrusion length H suitable for soldering.
