Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a connection device for electrically connecting at least two flat electric cables.

[0002] Flat electrical cables having a ribbon-shaped flexible insulating core with a series of parallel conductive tracks on one side are well known in the art.

Often, it is necessary to make a branch connection from these conductive tracks to another ribbon cable, and the branch connection of this ribbon cable is very complicated.

[0004] It is an object of the present invention to provide a practical and practical electric connection device which can easily form an electric connection between the tracks of a ribbon cable, and has a simple structure.

[0005] A connecting device according to the present invention is for electrically connecting at least two flexible insulated core-shaped ribbon cables each having at least one conductive track on one side, and is a vertically long one for accommodating the ribbon cables. A key member of a cylindrical main body having a slot, and an outer body having a cylindrical inner passage with one end opened and fitted to the cylindrical body, through which the ribbon cable can pass. With two longitudinal openings,
Further, a means for rotating the key member with respect to the exterior body is provided.

Due to the above-described features, all that is necessary to electrically connect the two ribbon cables is to have the conductive tracks face each other so that the ribbon cables are inserted into the slots in the key member and the ribbon cables are inserted into the openings. The exterior body is fitted to the key member so as to penetrate the key body, and then the exterior body is held against the key member so that the ribbon cable is gripped between the outer surface of the cylindrical body and the inner surface of the exterior body in the slot. The rotation is about 90 degrees, which ensures the electrical connection of the ribbon cable due to the contact pressure between the tracks.

According to another feature of the invention, the cylindrical body has a button at one end for actuating the cylindrical body.

According to another feature of the invention, the surface of the actuation button adapted to face the outer casing has at least one detent which corresponds to the interconnection of the ribbon cable. A fixing means for fixing the exterior body to the button at the angular position is configured.

Finally, according to a last feature of the invention, the outer body has an end wall with a central hole and the free end of the cylindrical body has a nipple adapted to be inserted into the central hole. .

The present invention will be described in detail below with reference to embodiments shown in the accompanying drawings.

The illustrated device comprises a key member 1 in the form of a cylindrical body having a button 2 at one end for actuating it and a nipple 3 at the other end.

The cylindrical body has an elongated slot 5 extending from the free end to a point near the button 2.

The device is completed by an outer body 21 which is open at one end 9 and closed at the other end by an end wall 7 which has a smaller diameter than the nipple 3. A central hole 8 is formed.

Since the outer body 21 has an inner diameter corresponding to the outer diameter of the cylindrical main body, the main body can be fitted to the outer body 21.

The exterior body 21 extends to near the end wall 7.
It has two longitudinal openings 6 and is open at the end 9. The openings 6 are formed in the same plane in diameter.

The end 9 has a detent 10, and the surface of the button 2 facing the cylindrical body also has a detent 4.

The ribbon cable 1 comprises an insulating core 12 having a series of tracks 13 to 16 which are good conductors.

FIG. 1 shows a second ribbon cable 17 having an insulating core 19 and two activations 18 and 20.

In order to electrically connect the tracks 18 and 20 to the tracks 15 and 16, the cable 17 is inserted into the slot 5 after the cable 11 is inserted into the slot 5, so that the tracks 18 and 20 are And 16, and then the sheath 21 is mounted so that the cables 11 and 17 pass through the openings.

When the outer body 21 is mounted on the cylindrical body, the nipple 3 undergoes some elastic deformation and penetrates through the central hole 8, so that the two components cannot be separated and the outer body 21 is circular. End 9 to secure to the body in the circumferential direction
Are joined to the rotation stopper 4.

In order to form an electrical connection, the exterior body 21 is rotated by 90 degrees with respect to the key member 1 (see FIG. 3),
Detents 4 and 10 hold the two components in this angular position.

In the embodiment shown, a detent 4 and a detent 10 are provided for circumferentially locking the two components, but the two components are shown in FIG. One detent member can be provided on the button 2 or end 9 to lock in the angled position.

The present invention is not limited to the embodiments shown and described above, and various changes or modifications can be made without departing from the scope of the invention. For example, the exterior body can be provided with a fixing mechanism that can fix the exterior body to the support.
