Description

[Detailed Description of the Invention] [Summary of the Invention] Printed wiring is formed on a base layer of an insulating flexible material, an insulating sheet of the insulating flexible material is applied on the printed wiring base layer, and both edges of opposing surfaces of the base layer and the insulating sheet are formed. A flexible cable with terminals fixed to it and a metal fitting with multiple needle terminals arranged at the same pitch as multiple conductor wires of printed wiring are held in a housing. By inserting a connector between the cable and the insulating sheet and connecting the metal object with needle-like terminals and the conductor wire, it is possible to cut the flexible cable to any length and connect the cut part to the connector with terminals. It is economical and has excellent workability on site, without compromising the aesthetics of wiring between rooms in the house.

[Industrial application field]

The present invention relates to a flexible cable as an in-house communication line used for telephone wiring, etc., which is excellent in on-site wiring workability, aesthetics, and economical efficiency, and its connector.

[Conventional technology]

Conventional communication lines of this type use round conductors (diameter: 0.65 m).
It has a structure in which multiple wire rods (mφ or 0.4 mmφ) with insulating jackets are arranged in parallel and twisted together.1.When wiring telephone wires indoors in a general home,
Fasteners (Stella Pull) and protective materials (wire protectors)
All three were used and installed on the wall or floor. :Prior art 1 On the other hand, printed wiring cables are widely used in data terminal equipment and the like for signal transmission between circuit boards, in which a large number of conductor wires are printed on a flexible sheet of insulators, and the entire outer surface of the cable is coated with insulation. However, this cable is shipped with a complete wiring pattern created according to the required dimensions at the time of manufacture, both ends treated to allow soldering, and all connector terminals already connected. :Prior art 2 [Problem to be solved by the invention] In conventional technology 1, when extending across a room, the external cross section of the cable becomes large, so it is necessary to route the cable through gaps between doors and sliding doors. It is impossible to do so, and it is necessary to make a hole in the wall and run the extension through that hole, which requires time and effort for wiring and also spoils the aesthetics.

In addition, when conventional technology 2 is used for indoor telephone lines, etc., the cable length varies depending on the room layout and wiring conditions, so if the cable is of a standard length, there will be excess length, resulting in poor aesthetics. , it had not been put to practical use. In addition, in the above printed wiring cable, when the cable is cut into arbitrary dimensions along the way, there is no method for connecting lead terminals or connector terminals, and there is no terminal component.

[Failure to solve the problem]

In order to solve the conventional problems, the present invention provides a flexible 7-pull cable in which a plurality of conductor wires are printed and arranged on a base layer made of an insulated flexible material to form a conductor part, and the conductor part is A flexible cable in which the upper surface of a base layer is coated with an insulating sheet made of an insulating flexible material, includes a fixing part that fixes both edges of opposing surfaces of the base layer and the insulating sheet, and the conductor part is attached to the base layer. It is characterized by being fixed.

Furthermore, the above-described connector for a flexible cable of the present invention is arranged at a pitch that matches the pitch of the conductor portions of the flexible cable, and is inserted between the base layer and the insulating sheet from the longitudinal direction of the flexible cable to connect the conductor portions. The present invention is characterized by comprising a plurality of metal fittings with needle-like terminals connected to the parts, and a housing for holding the metal fittings with needle-like terminals.

[For production]

In the present invention, the conductor portion of a flexible cable with printed wiring is configured so that it does not adhere to the insulating sheet, and after cutting the flexible cable to the desired length,
A metal object with a needle-shaped terminal is inserted from the cut end into the gap between the base layer and the insulating sheet while making contact with the conductor part to form a printed wiring cable with a connector, which improves on-site wiring workability, aesthetics, and economy. Improves sexual performance. This will be explained below with reference to the drawings. - [Example] Fig. 1 shows an example of the present invention. 1 is a conductor part, 2 is a base layer, and 2' is a fixing part that fixes both edges of opposing surfaces of the base layer 2 and the insulating sheet 3.

The base layer 2 is made of an insulating sheet, and the conductor portion 1 made of steel is entirely wired on its surface by printing or bonding to form a signal transmission line. Furthermore, an insulating sheet 3 of the same quality as the base layer 2 is covered on top of the cable to form a printed wiring cable. Here, the base layer 1 and the insulating sheet 3 are bonded together at the edges so as not to touch the conductor part 1 as shown in FIG.
In FIG. 1, a fixing portion 2' is formed so as to fix only the shaded portion.

FIG. 2(a) is a sectional view of the flexible cable shown in FIG. 1, which has a gap between the conductor portion 1 and the insulating sheet 3 in which a needle-shaped terminal or the like can be inserted.

FIG. 2(b) shows another embodiment of the flexible cable of the present invention, in which the conductor portion forms two conductor layers so that the gap between the base layer 2 and the insulating sheet 3 does not expand unnecessarily. 1 is also an example of a fixed configuration.

FIG. 3 shows an embodiment of the terminal material connector connected to the flexible cable of the present invention, where 4 is a metal fitting with a needle-like terminal, and 5 is a nozzle.

FIG. 4 is a cross-sectional view of the embodiment in which the connector with terminals shown in FIG. 3 is connected to a flexible cable. 1st
Cut the flexible cable shown in the figure to the required length, insert the needle-like terminal fitting 4 of the terminal-equipped connector shown in Fig. The metal fittings 4 with needle-like terminals are brought into contact.

The other end of the metal fitting 4 with a needle-shaped terminal is used as a soldering part or as a connection terminal 7 for connecting to another conductor wire.

On the other hand, the housing 5 can be opened freely, and when the housing 5 with the flexible cable inserted between them is closed, sufficient contact force is ensured between the conductor part 1 of the flexible cable and the metal fitting 4 with the needle terminal. electrical connection can be achieved. Furthermore, after the housing 5 is closed, it is fixed with screws 6 or the like to ensure long-term contact reliability.

〔Effect of the invention〕

As explained above, the present invention is capable of cutting a printed wiring cable to an arbitrary length and connecting a connector with a terminal to the cut portion on-site, which improves workability and
Since the cable is thin, it can be extended between rooms in the house using gaps between doors and sliding doors, and has the advantage of being able to realize wiring that is aesthetically pleasing, easy to work with, and economical. be. Furthermore, since it is thin, it is possible to write numbers on the bottom of carpets, furniture, tatami mats, etc., and has a wide range of uses. Further, in this embodiment, an example of use as a telephone line has been described, but it can be similarly used as a signal line to a home security sensor for checking gas leakage or door locking. Further, although the number of conductors is described as two, there is no particular problem even if the number of conductors is further increased.
