JP6859198B2 - Heterogeneous shield connection method - Google Patents

Description

The present invention relates to a heterogeneous shield connection method.

Conventionally, a shielded cable having an electromagnetic shield function has been used for the high-voltage cable so that the electromagnetic waves emitted from the high-voltage cable do not adversely affect surrounding devices, and the shielded cable is an insulator such as polyethylene. The core wire covered with the above is covered with a shield woven into a cylinder with a copper wire or the like, and the outer periphery thereof is further covered with a resin sheath (protective outer coating).

This type of shielded cable includes an individual shielded cable in which the core wires are individually coated with a shield (hereinafter referred to as an individual shield) and a plurality of core wires collectively coated with a shield (hereinafter referred to as a collective shield). Since there are two types of collective shielded cables, various devices have a receiving structure that matches either the individual shielded cable (see Patent Document 1 below) or the collective shielded cable (see Patent Document 2 below). Will be prepared.

However, if you want to connect devices that support different types of individual shielded cables and batch shielded cables to each other, we will develop a new device that has a receiving structure changed to match one of them in order to unify it to either type. There is a problem that such new development causes a significant increase in cost.

The present invention has been made in view of the above circumstances, and an object of the present invention is to realize interconnection between devices corresponding to different types of individual shielded cables and collective shielded cables without newly developing one device. And.

In the present invention, the sheath at the end of a plurality of individual shielded cables is removed over a required range to partially expose the individual shield, and a sleeve is inserted between the exposed individual shield and the core wire. A collective shield that can be pushed to the position where it abuts on the sheath, and the plurality of individual shields can be bundled and fixed with tape in front of the pushing position so that the sleeve does not return from the pushing position, and a plurality of core wires can be covered together. The present invention relates to a different type of shield connecting method, characterized in that the individual shields bundled with the tape are covered with a band, and the portions corresponding to the pushing positions of the sleeves in the collective shield are bound with a band.

Thus, in this way, the sleeve is pushed between the exposed individual shields at the ends of the plurality of individual shielded cables and the core wire to protect the core wire and to prevent the band from binding. By creating a structure that makes it easy to take force, and fixing each of the individual shields with tape, wrapping them together with a collective shield and binding them with a band, the individual shields and the collective shield can be reliably surfaced. It is possible to make good equipotential by contacting and connecting them to ensure continuous continuity with each other.

As a result, the ends of multiple individual shielded cables are reconfigured in the form of a collective shielded cable that is collectively covered by a collective shield, thereby providing an existing device with a receiving structure that matches the type of collective shielded cable. Even if you want to connect a device that supports individual shielded cables and a device that supports batch shielded cables to each other, you can change the receiving structure to one of them in order to unify it into one of the formats. There is no need for new development.

Further, in the present invention, as a collective shield for covering each individual shield bundled with tape, a collective shield provided in the connector for the collective shielded cable is used, and the core wire of each individual shielded cable is passed through the collective shield. Is preferably connected to the terminal of the connector, and in this way, it is possible to easily connect to an existing device having a receiving structure matching the type of the collective shielded cable via the connector. ..

According to the different types of shielded connection method of the present invention described above, it is possible to realize interconnection between devices corresponding to different types of individual shielded cables and collective shielded cables without newly developing one device. By making it possible to use the existing equipment as it is without the need for new development of such equipment, it is possible to achieve various excellent effects that the cost can be significantly reduced.

It is the schematic which made the individual shield at the end of a plurality of individual shielded cables exposed. It is the schematic which shows the state which the sleeve is inserted between the individual shield of FIG. 1 and the core wire. It is the schematic which shows the state which pushed the sleeve of FIG. 2 to the position which abuts against a sheath. It is the schematic which shows the state which each individual shield was bundled and fixed by the tape before the pushing position of the sleeve of FIG. It is the schematic which shows the state which covered each individual shield of FIG. 4 with a collective shield and bound with a metal band.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 5 show an example of an embodiment of the present invention. In this embodiment, as shown in FIG. 1, the sheath 2 at the end of a plurality of individual shielded cables 1 is removed over a required range. The individual shield 3 is partially exposed, and then the sleeve 5 is inserted between the exposed individual shield 3 and the core wire 4 as shown in FIG. 2, and as shown in FIG. The sleeve 5 is pushed to a position where it abuts against the sheath 2, and as shown in FIG. 4, the plurality of individual shields 3 are bundled and fixed by tape 6 in front of the pushing position so that the sleeve 5 does not return from the pushing position. ..

Then, as shown in FIG. 5, each individual shield 3 bundled by the tape 6 in this way is covered with the collective shield 8 (a plurality of core wires 4 collectively) provided in the connector 7 for the collective shielded cable. A metal band 9 is used to bind the portion of the collective shield 8 corresponding to the pushing position of the sleeve 5 to cover the collective shield 8).

Here, the core wire 4 of each individual shielded cable 1 is connected to the terminal 7a of the connector 7 through the collective shield 8, and the outer periphery of the collective shield 8 and the metal band 9 is shown here. It is advisable to wrap an insulating tape or the like (not shown) instead of the sheath to protect the insulation.

Reference numeral 10 in FIGS. 1 to 5 indicates a connector for the individual shielded cable 1 as before, which remains at the opposite end of the individual shielded cable 1, and the individual shielded cable 1 is connected via the connector 10. It is possible to connect to an existing device that has a receiving structure that matches the format.

Thus, in this way, the sleeve 5 is pushed between the exposed individual shields 3 and the core wires 4 at the ends of the plurality of individual shielded cables 1 to protect the core wires 4 and metal. By creating a structure that makes it easy to take the reaction force at the time of binding by the band 9, the individual shields 3 are bundled and fixed by the tape 6, then wrapped together by the collective shield 8 and bound by the metal band 9. It is possible to ensure that the individual shields 3 and the collective shield 8 are in surface contact with each other and are connected to each other to ensure continuous conduction with each other and to achieve good equipotential bonding.

As a result, the ends of the plurality of individual shielded cables 1 are reconfigured as a batch shielded cable type in which the ends of the plurality of individual shielded cables 1 are collectively covered by the batch shield 8, whereby the existing device having a receiving structure matching the batch shielded cable type. Even if you want to connect the device compatible with the individual shielded cable 1 and the device compatible with the collective shielded cable to each other, the receiving structure is changed according to one to unify to either format. There is no need to develop new equipment.

Further, particularly in this embodiment, the collective shield 8 provided in the connector 7 for the collective shield cable is used as the collective shield 8 for covering each individual shield 3 bundled by the tape 6, and the inside of the collective shield 8 is used. Since the core wire 4 of each individual shielded cable 1 is connected to the terminal of the connector 7 through the cable, it is easy to connect an existing device having a receiving structure according to the type of the collective shielded cable via the connector 7. It becomes possible to make a connection.

Therefore, according to the above embodiment, it is possible to realize interconnection between devices corresponding to different types of individual shielded cables 1 and collective shielded cables without newly developing one device. Costs can be significantly reduced by being able to use existing equipment as it is without the need for new equipment development.

The different types of shielded connection method of the present invention is not limited to the above-mentioned embodiment, and can be applied to the connection between the individual shield and the collective shield in the direct connection between the individual shielded cable and the collective shielded cable. Of course, various changes can be made without departing from the gist of the present invention.
