Abstract

Having conductive contacts (4), a first insulator (1) retaining the contacts, and a cable-side insulator, attachable/detachable relative to the first insulator, for retaining a flat cable (6). The cable-side insulator includes a second insulator (2) for receiving the flat cable, a third insulator (3) disposed so as to confront the second insulator via the flat cable, and a clamp (7) interposed between the flat cable and the third insulator. When the cable-side insulator is mounted to the first insulator, the second and third insulators are engaged with the first insulator to approach each other so that the flat cable is sandwiched between the clamp and the second insulator. In this state, the flat cable is connected to the contacts.

Claims

1. A connector including conductive contacts, a first insulator retaining said contacts, and a cable-side insulator, attachable/detachable relative to said first insulator, for retaining a flat cable, wherein when said cable-side insulator is mounted to said first insulator, said flat cable is connected to said contacts, said connector characterized in that said cable-side insulator comprises a second insulator for receiving said flat cable, a third insulator disposed so as to confront said second insulator via said flat cable, and a clamp interposed between said flat cable and said third insulator, said third insulator having a rib pressing said clamp towards said flat cable, and, when said cable-side insulator is mounted to said first insulator, said second and third insulators are engaged with said first insulator to approach each other so that said flat cable is sandwiched between said clamp and said second insulator.

3. A connector according to claim 1, wherein said first insulator has a guide groove for guiding said cable-side insulator to be attached/detached, and said second and third insulators have convex portions, respectively, which are inserted into said guide groove.

4. A connector according to claim 1, wherein said second insulator has a concave portion confronting said clamp, and said flat cable is pushed into said concave portion by said clamp.

5. A connector according to claim 1, wherein said flat cable comprises a plurality of cable elements, and said second insulator and said clamp have a function of conjointly arraying said cable elements.

6. A connector according to claim 1, wherein said third insulator is an integral body.

2. (Canceled)

7. A connector including conductive contacts, a first insulator retaining said contacts, and a cable-side insulator, attachable/detachable relative to said first insulator, for retaining a flat cable, wherein when said cable-side insulator is mounted to said first insulator, said flat cable is connected to said contacts, wherein said cable-side insulator comprises a second insulator for receiving said flat cable, a third insulator disposed so as to confront said second insulator via said flat cable, and a clamp interposed between said flat cable and said third insulator, said third insulator comprises an additional insulator having the same shape and size as said second insulator, and an additional clamp interposed between said additional insulator and said clamp and, when said cable-side insulator is mounted to said first insulator, said additional insulator along with said second insulator is engaged with said first insulator to cause said additional clamp to approach said second insulator so that the foregoing clamp is pushed toward said second insulator by said additional clamp, thereby clamping said flat cable between the first-mentioned clamp and said second insulator.

8. A connector according to claim 7, wherein said additional insulator directly contacts with said additional clamp.

9. A connector according to claim 7, further comprising additional conductive contacts retained by said first insulator and connected with an additional flat cable, wherein said additional flat cable is sandwiched between said additional insulator and said additional clamp.

wherein

said connector comprises contacts to be connected with wires of said flat cable, a first insulator retaining said contacts, a second insulator for arraying the wires of said flat cable and formed with a concave portion for receiving said flat cable, a clamp for sandwiching said flat cable conjointly with said second insulator, and a third insulator formed with a rib to be brought into contact with said clamp,

when connecting said two flat cables, a plurlaity of said second insulators, two in number, and a plurality of said clamps, two in number, are used such that said two clamps are caused to confront each other, and said first insulator and said two second insulators are fixed together, and

when connecting said one flat cable, said one second insulator, said one clamp, and said third insulator are used such that said clamp and said rib of the third insulator are brought into contact with each other, and said first insulator, said second insulator, and said third insulator are fixed together.
