Description

[Detailed Description of the Invention] The present invention relates to a cable in which a multi-terminal connector for connection with equipment is attached to a terminal.

There are various types of cables used for signal transmission within a device or between devices, but cables with multi-terminal connectors attached at both ends that are connectable to a multi-terminal connector provided within the device are often used.

FIG. 1 is a perspective view of a conventional cable with a multi-terminal connector.

This cable is terminated as follows.

In the figure, a large number of insulated core wires 1 coated with plastic coating, such as polyethylene or vinyl chloride resin, are assembled,
At the terminal of a multi-core cable 4 whose outer periphery is coated with a braided shielding layer 2 made of tin-plated copper wire or the like, and whose outermost layer is coated with a jacket 3 made of polyethylene or vinyl chloride resin,
After exposing the core wires 1 and arranging the core wires 1 in parallel in a predetermined order, the core wires are bonded at predetermined intervals using an adhesive or heat-sealing treatment to form a parallel portion 5. Attach the multi-terminal connector 6 to the terminal.

This multi-terminal connector is called a one-touch connector, in which when insulated core wires arranged in parallel at predetermined intervals are inserted, the terminals corresponding to each core wire can be electrically connected without removing the plastic coating.

In such a cable terminal, if you want to electrically connect the shielding layer 2 to the terminal of the connector 6, use a drain wire cut from a bare tin-plated copper wire that has been inserted into the cable so that it comes into contact with the shielding layer 2. Requires separate electrical connection to designated terminals.

In this work, it is necessary to solder the drain wire to a predetermined terminal before attaching the connector.

In addition, for cables that do not have a drain wire,
As shown in FIG. 1, it is also necessary to separately prepare a ground wire 7 and solder it to the end of the shielding layer 2.

Moreover, in the terminal of the conventional cable as described above, the ground wire 7 and the other core wire 1 are separated, so there is a problem that the ground wire 7 is particularly easy to break.

The present invention has been developed in view of the above points, and provides a cable with a multi-terminal connector in which the connection of the ground wire is completed at the same time as the connector is attached.

FIG. 3 is a plan view of the terminal portion of the cable according to the present invention;
FIG. 2 is a sectional view of a core wire used as a ground wire.

The cable shown in Figure 3 has the same structure as the conventional cable explained in Figure 1 for the most part, and the same parts are given the same symbols, but some of the core wires of this cable are shielded within the cable. At least one core wire, for example a core wire 8, in contact with the layer 2 is characterized in that, as shown in FIG. There is.

Terminal treatment of the cable 68 is carried out as follows.

For example, when all the core wires have a polyethylene insulation coating, all the core wires exposed at the cable end are arranged in parallel at a predetermined interval, and then each wire is heat-sealed using a hot press or the like to form a parallel portion.

At this time, the core wires having the semiconducting polyethylene coating are also placed at the ends of the rows and fused at the same time.

Thereafter, by attaching the connector 6 to the parallel portion 5 as shown in FIG. 3, the connection of the signal wire core 1 and the ground wire core wire 8 is completed at once.

Note that the core wire 8 having the conductive plastic coating is
It is preferable that it is made of the same material and has the same outer diameter as the other core wires, and is either twisted with the core wires used during cable manufacturing so that it is the outermost layer, or is layered separately from the other core wires in a shielding layer. Attach vertically to the inside of.

The multi-terminal connector cable of the present invention described above is
Since the ground wire forms a parallel part integrally with other core wires, the connection work to the connector is easy, and there is no risk of breakage even if the ground wire is not separately reinforced.
