Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector connecting cable having an adhesive layer coated on the tip of the cable for attaching a connector.

Generally, when attaching a connector to the tip of a cable, the core wires at the tip are lined up horizontally in parallel at a fixed pitch, and each core wire has a plate-like part connected together by heat fusion or the like. It's convenient to have.

As a cable having such a plate-like part,
There are flat cables, blind cables, ribbon cables, interface cables, etc. For example, FIG. 1 shows an example of connecting an interface cable 1 and a connector. This interface cable 1 has a plate-like part 3 formed at its tip by integrating all the core wires 2 by heat fusion or the like, and one surface of this plate-like part 3 is flat, and A recess 4 is provided between each core wire on the other surface along the length thereof.

On the other hand, the connector is made up of a connector body 5 connected to the interface cable 1 and a connector cover 6. The upper surface of the connector body 5 has a connector body 5 arranged at the same pitch as the pitch of each core wire 2 of the plate-shaped portion 3. A plurality of contact blades 7 are arranged side by side, and on the lower surface of the connector cover 6, a plurality of ribs 8 which fit into the recesses 4 are formed protrudingly in a substantially wavy shape.

When connecting these interface cables 1 and connectors, connect the tip of the plate-like part 3 to the core wire 2.
The ribs 8 of the connector cover 6 are held in a state where they are fitted into the recesses 4, and each core wire is pressed against the connector body 5 so as to fit into the contact blade 7. It's meant to make you dig into it. In this case, there is a problem that the rib 8 easily comes off from the recess 4, resulting in poor workability.

Further, in order to accurately and easily perform the connector installation work, a wiring tool shown in FIG. 2 has been conventionally used.

That is, the connector cover 6 is inserted into the groove 10 of the locator plate 9, and the side edges of the flat cable 12, etc. are guided by the guide pieces 11, 11 provided perpendicularly to the groove 10, and the connector cover 6 and the plate are connected. After aligning the connector body 5 with the plate part 3, the connector body 5 is placed on the plate part 3, and the pressing tool 13 is pressed.
Press the connector and flat cable 12 with
It is used to connect with other devices.

However, if the lengthwise dimension of the core wire 2 of the plate-shaped portion 3 is short, the tip of the core wire 2 cannot be accurately aligned, resulting in problems such as uneven work.

The present invention was developed in consideration of the above-mentioned circumstances, and aims to provide a connector connecting cable that allows the connector to be attached to the plate-shaped part of the cable accurately and easily. The present invention is characterized in that an adhesive layer is provided in the depression between each core wire in the connector, and this adhesive layer can prevent misalignment after alignment with the connector.

Hereinafter, a description will be given based on the embodiments shown in the drawings.

3 to 6 show an embodiment of the interface cable of the present invention. The core wires 15 at the tip of the interface cable 14 are arranged horizontally in parallel at regular intervals, and the core wires 15 are connected together by heat fusion or the like to form a plate-shaped portion 16. Plate portion 16
A recessed portion 17 extending along the length of the core wire 15 is provided in an uneven manner between each core wire on one surface of the core 15, and the other surface is formed in a planar shape. Further, an adhesive layer 18 made of a pressure-sensitive adhesive is applied to the recessed portion 17, and a release paper 19 is pasted on the adhesive layer 18.

Next, a method of attaching a connector to such a connector connection cable will be explained.

First, the tip of the plate-shaped portion 16 is trimmed so as to be perpendicular to the length direction of the core wire 15. Next, the release paper 19 is removed from the plate-shaped portion 16 to expose the surface of the adhesive layer 18. Then, while aligning the ends of the cut plate portions 16 as a reference, the connector cover 6
is pressed against the adhesive layer 18, and the rib 8 is pressed against the adhesive layer 1.
8 to fit into the recess 17. At this time rib 8
By being guided by the recessed part 17, the connector cover 6 is further guided to a proper position with respect to the plate-like part 16, and the connector cover 6 and the plate-like part 16 are adhesively fixed to each other by the adhesive layer 18. (See Figure 5). After that, on the connector body 5,
The plate part 16 to which the connector cover 6 is fixed is pressed, and the contact blade 7 is electrically connected to each core wire 15 of the plate part 16 (see FIG. 6). Therefore, the position of the plate portion 16 does not shift between the connector body 5 and the connector cover 6 during the connector attachment operation.

Note that if a material with appropriate hardness, such as thick cardboard or plastic board, is used as the release paper 19, external forces and residual stress that are likely to occur during the manufacture of the plate-shaped portion of the interface cable can be avoided. This is effective in maintaining the flatness of the plate-like part because it can prevent the plate-like part from being deformed by the process.

As explained above, according to the present invention, a plurality of core wires are arranged horizontally in parallel at a fixed pitch in at least a portion of the length of the cable, and each core wire is integrally connected to the plate-shaped portion. , and a recess along the length direction of the core wire is provided between each core wire on at least one surface of this plate-shaped portion, and an adhesive layer is provided in this recess. When connecting a connector to the invented cable, the following effects can be obtained.

By fitting the ribs of the connector cover into the recesses, the connector cover can be guided to an appropriate position relative to the plate-like portion.

By removing the release paper, the adhesive layer can be made usable at will, and
Due to the action of this adhesive layer, the plate-like part of the cable can be fixed to the connector, so there is no misalignment of the positional relationship between each core wire and the plate-like part during connection work to the connector, and the cable can be fixed to the connector. The workability of connecting to the connector is improved.

Since the connector cover and the plate-shaped portion are fixed to each other in an appropriate positional relationship, a simple press device may be used as the connection tool.

Adjacent core wires are connected to each other by the release paper attached to the adhesive layer, so while expanding the recesses between the core wires, both ends of the cable droop and the cross section tends to curve. deformation is prevented.
