Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a flat cable connector.

[Background technology]

A typical undercarpet wiring system is
The flat cable 1 shown in FIG. 2 is constructed by disposing an upper surface protection sheet (not shown) and a lower surface protection sheet (not shown) on the upper and lower surfaces. flat cable 1
This is a device in which band-shaped flat conductors 1a are arranged in parallel at a predetermined interval and covered with an insulating member 1b, and perforations 1c for connector attachment are made in the insulating parts between the band-shaped flat conductors 1a. A metal connector 2 as shown in FIG. 1 has been proposed for connecting such flat cables 1, 1 to each other in a T-shape as shown in FIG. That is, this connector 2 has substantially V-shaped gripping parts 2b, 2b' connected vertically and horizontally to both sides of the strip-shaped piece 2a, and both gripping parts 2b, 2
A ring-shaped electrical connection protrusion 2c is punched and formed on the inner surface of b', and a tongue-shaped mechanical connection protrusion 2c is punched out.
d is cut and raised, and the upper and lower surfaces of each flat cable 1, 1 are held between the two gripping portions 2b, 2b' using a special tool. As a result, the electrical connection protrusion 2
c breaks through the insulating member 1b of the cable 1 and contacts the conductor 1a, thereby electrically connecting both cables 1, 1. At the same time, the mechanical connection protrusions 2d protruding from opposite sides of the gripping part 2 connect the cable The two cables 1, 1 are mechanically connected to each other by penetrating through the cables 1, 1, and 1, thereby preventing the grip portion 2b from opening.

However, the bent pieces 2b 1 _and 2 of both gripping parts 2b and 2b'
b ₁ ′ both face the front side, and the strip 2a
must be placed overlapping the bottom surface of the lower flat cable 1, so when the flat cable 1 is laid in a cross shape, the bent piece _2b1 of the vertical grip part 2b cannot be used and the connection will be difficult. The drawback is that it cannot be done.

[Purpose of the invention]

The object of the present invention is to provide a flat cable connector that can be connected both when the flat cable is laid in a T-shape and in a cross-shape.

[Disclosure of the Invention] In the flat cable connector of the present invention, the bent piece forming the gripping portion at one end of the strip-shaped piece is bent toward the front side, and the bent piece forming the gripping portion at the other end is folded toward the back side. It is bent. The bent piece at one end is provided at an extended position of the strip-shaped piece, and the bent piece at the other end is provided to extend laterally.

In this way, since the double-folded pieces are provided on the front and back sides, the strip-like pieces can be placed on the overlapping surfaces of the upper and lower flat cables, making it possible to connect both cross-shaped wiring and T-shaped wiring. I can do it.

An embodiment of this invention is shown in FIGS. 4 to 7. That is, this flat cable connector 4 has a bent piece 6a at one end of the strip-like piece 5, with an extension of this end bent toward the front side, and this bent piece 6a.
A substantially V-shaped first gripping part 6 is provided, and a bent piece 7a extending laterally and bent to the back side is provided at the other end of the strip-shaped piece 5, and this bent piece 7
A substantially V-shaped second gripping portion 7 is provided, and an electrical connection projection 2c and a mechanical connection projection 2d are provided on the inner surfaces of these gripping portions 6 and 7. These protrusions 2c and 2d are the same as in the example shown in FIG. The double-folded pieces 6a and 7a are 2
The book is folded into two stages by parallel folding parts 8, and a plurality of holes 9 forming a narrow width part are provided in one row at the center between the two folding parts 8. In addition,
The mechanical connection protrusion 2d is cut and raised in a direction perpendicular to the bent portion 8.

In this way, the bent pieces 6a at both ends of the strip-shaped piece 5,
Since the strips 7a are provided on the front and back sides, the strip-shaped piece 5 is placed on the overlapping surface of the upper and lower flat cables 1, and the upwardly bent piece 6a is overlapped on the upper surface of the upper flat cable 1, and then bent downward. The piece 7a can be stacked on the underside of the lower flat cable 1. Therefore, connection can be made at the intersection of both the cross-shaped wiring and the T-shaped wiring of the flat cable 1.

The bent pieces 6a, 7a of both gripping parts 6, 7 are bent at two bent parts 8, and a hole 9 is formed between the bent parts 8.
Since the narrow part is provided by forming the bending piece 6
When a and 7a are further bent to sandwich the flat cable 1, they are bent at the narrow part. Therefore, the bent pieces 6a, 7a of both gripping parts 6, 7 are
b, 7b, and the mechanical connection protrusion 2d cuts into the flat cable 1 perpendicularly. Therefore, the flat cable 1 can be easily bitten into the cable, and the cable can be surely penetrated without the mechanical connection protrusion 2d falling down or bending pieces 6a and 7a being bent. Since the mechanical connection protrusion 2d faces perpendicularly to the bent portion 8, this also ensures that the mechanical connection protrusion 2d will fall apart and bite.

In addition, although both the electrical connection protrusion 2c and the mechanical connection protrusion 2d are provided in the above embodiment, since the mechanical connection protrusion 2d provides electrical continuity, the electrical connection protrusion 2c does not necessarily need to be provided. .

〔Effect of the invention〕

The flat cable connector of the present invention has the advantage that it can be connected both when flat cables are laid in a cross-shape and in a T-shape.
