Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a terminal board having a regularly arranged multi-terminal structure for electrically connecting assemblies such as printed circuit boards, and a method for manufacturing the same. It is.

Conventionally, when permanently connecting the terminals of assemblies with regularly arranged multi-terminal structures in electronic equipment, multiple conductors were arranged in parallel and the rest except for both ends was insulated with an insulator. A terminal board with a similar structure is used.
Lead wires made of conductors at both ends of the terminal plate were inserted into the terminals of the assembly and connected by welding or soldering.

FIG. 1 shows an example, where 1 is a lead wire and 2 is an insulator.

Conventionally, this type of terminal board has generally been manufactured by molding using a compression molding machine, and molding requires a large number of steps to supply the conductor to the mold and position it. At times, it was not possible to mold thin conductors due to the pressure applied.

Further, it is difficult to manufacture the terminal plate unless the longitudinal dimension (L in FIG. 1) is at least several mm or more.

However, the users of this type of terminal board are required to make L approximately 1 mm in order to improve the packaging density, and in order to obtain a terminal board that satisfies this requirement with the conventional structure, the width of the insulator must be short. Therefore, it became mechanically weak and the insulator easily broke during the manufacturing process, making it difficult to mass produce and making it quite expensive.

The present invention aims to eliminate these drawbacks and to provide a terminal board capable of improving packaging density, as well as to automatically and easily manufacture such a terminal board. The main feature is that one end has an insulator that holds and fuses the conductor from both sides, and the other end has an insulator that is removably adhered to one side of the parallel conductors, and has a constant repetition period in the length direction. The second feature is that the shape, size, and arrangement position of the windows of two pieces of insulating tape are selected, the conductor is sandwiched and fused between the two sheets of insulating tape, and the conductor is then cut at predetermined repeated positions. That is.

Hereinafter, embodiments will be described based on the drawings.

FIG. 2 shows an outline of the method for manufacturing the terminal board of the present invention.
A plurality of conductors 11 arranged at predetermined intervals are sent out from the conductor sending device 3.

As the conductor 11, a single conductive metal wire, a stranded wire, a bulk coated wire coated with tin or solder, or the like is used.

4 and 5 are plastic tape feeding devices, from which plastic tapes 8 and 9 having windows 6 and 7 formed therein are fed out as shown in FIGS. 3a and 3b.

Now, if the dimensions of the plastic window in Figure 3a are, for example, the length in the tape width direction a and the length in the tape length direction as b, then the hole in the plastic tape 9 in Figure 3 is the same as the tape width. If the lengths in the direction and longitudinal direction are c and d, respectively, then c=
a, d\b, and when the two plastic tapes 8 and 9 are sent out from the plastic tape sending devices 4 and 5, and the conductor 11 is sandwiched and fused by the heated pressure roll 10,
Front edge of the window with two pieces of plastic tape (AA in Figure 3a)
and BB) in Figure 3 should match.

In this case, the plastic tape is made of polyethylene (PE).
) A thermoplastic material such as polyvinyl chloride (PVC) or a composite material in which a material having a higher softening point than these materials is laminated in advance is used.

In Figure 4, two plastic tapes 8 and 9 are connected to the conductor 11.
The figure shows the state in which they are sandwiched and fused into one body.

In the figure, 11 is a conductor, 6 is a window punched in plastic tape 8, and 9 is a plastic tape having a window shorter in the tape length direction than plastic tape 8, and the front edges of both windows are aligned. Since it is glued together, the part corresponding to the difference in length between the two windows will only have plastic on one side.

The plastic tape with the conductor 11 sandwiched and fused in this manner is cut off at both longitudinally continuous edges in the slitter 12, and is wound up on a take-up roll 13 into the state shown in FIG.

Figure 3a shows the continuous wound terminal board as shown in Figure 5.
By cutting at the trailing edge C, a terminal plate as shown in FIG. 6 is obtained.

This terminal board consists of an insulator 2 which is integrated by sandwiching and welding the ends of parallel conductors 11 from both sides with plastic tapes 8 and 9, and a supporter 14 consisting of a portion where plastic tape 9 is applied only on one side. Therefore, the supporter 14 is firmly attached to the device to the extent that it can be easily removed.

Fig. 7 shows a connection section in which a terminal board with the above structure is mounted on a plurality of printed circuit boards, 15 and 16 are printed circuit boards, and 17, 18, and 19 are mounted on printed circuit boards 15 and 16, respectively. 20 is a terminal board of the present invention which, after removing the supporter 14, can be inserted into the printed circuit boards 15 and 16 from only one side of the conductor and soldered.

Also, if the height of the insulator 2 is less than the height of the parts 17 and 18 on the printed circuit board, it will not cause any problem after mounting, so it may be left as is. It acts as a purpose.

Also, this connection method requires that the gap between the printed circuit boards be 2~
It also enables connection within a narrow space of about 3 mm.

When using the above manufacturing method, it is possible to manufacture terminal boards easily and quickly in a continuous manner, and even terminal boards with short insulator lengths can be used as conductors because the spacer always holds the spacer between the conductors. It can be manufactured without any disturbance in the spacing, and therefore the terminal board obtained also meets the requirements for printed circuit boards with increasingly higher packaging densities.

Note that the terminal board with such a structure was originally manufactured by adhering two pieces of plastic tape each having a rectangular window with a constant repetition period, with the windows shifted in position, as shown in Figure 3a. can do.

Fig. 8 shows a state in which two plastic tapes 81 and 82 sandwich the conductor 11 and fuse it into a single body.If cut at the same period as the window repetition period starting from D, it is shown in Fig. 9. A terminal board like this is obtained.

2 is an insulator and 14 is a supporter, which can be used for exactly the same purpose as the terminal board shown in FIG. 2, and the same effect can be obtained.

As described above, the terminal board of the present invention makes it possible to improve the packaging density, and the method of manufacturing the terminal board of the present invention automatically and easily manufactures such a terminal board, which is economical. It is also excellent in terms of sex and is a dog of industrial effectiveness.
