Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a right-angled or straight-line connection of a flat cable.

[Conventional technology]

When connecting flat cables to each other, connect a compression terminal to the end of the flat cable, and connect the connection plate attached to the compression terminal and the connection plate attached to the compression terminal of the other flat cable to be connected perpendicularly or in a straight line. A connection section is used in which the connectors are stacked one on top of the other and connected by tightening with bolts. In this case, conventionally, an insulating tape was wrapped to insulate the connection portion, and a protective cover or the like was placed on top of the insulating tape to provide a protective layer.

[The problem that the idea aims to solve]

However, in this connection method, even though the bolts are insulated with insulating tape and covered with a protective cover, the insulating layer may be damaged if external pressure is applied due to the protrusions of the bolts at the bolt connections. There was a problem of damage or deterioration.

The purpose of the present invention is to solve the above-mentioned problems in flat cable connection parts and to provide a flat cable connection part that has stable insulation properties.

[Means and actions for solving the problem]

The gist of the present invention is that the mechanical properties of the insulation of the connection part are greatly improved by providing an insulating plate facing the bolt on the inner surface of the protective cover of the connection part.

That is, the above-mentioned object of the present invention is to provide a connecting plate which connects a compression terminal to the end of a flat cable by arranging a large number of conductors in a horizontal row and covering the outside with an insulating layer of rubber or plastic, and which is attached to the compression terminal; At the connection part where the compression terminal of the other flat cable to be connected is connected to the connection plate attached to the compression terminal of the flat cable, either perpendicular to each other or stacked in a straight line and tightened with bolts, the bolt part is placed in advance inside the protective cover that covers the entire connection part. This is achieved by a flat cable connection characterized by the provision of opposing insulating plates.

In the present invention, the insulating plate facing the bolt part is provided inside the protective cover so that the insulating tape will not be damaged by the protrusion of the bolt when pressure is applied from the outside, and even if the insulating tape is damaged. By providing an insulating plate so that the insulating plate can protect the insulation, it may be attached to the insulating tape side or inside the protective cover, or it may be attached with an insulating tape or an adhesive.

As for the material of the insulating plate, any material that has both insulating properties and mechanical strength can be used, such as Bakelite, Primix, and epoxy glass substrate.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited to this embodiment.

In Figure 1, W ₁ is one flat cable, W _{2 is}
is the other flat cable that is its counterpart. The ends of both cables are compressed and connected to compression terminals 4a, the connection plates 4b of both compression terminals are overlapped, and the connection is made by tightening bolts 5. Wrap insulating tape 6 around the entire connection,
A protective cover 7 with an insulating plate 8 pasted is placed over the bolt connection.

In the above embodiments, the case where the cables are connected perpendicularly to each other is exemplified, but the present invention can also be applied to a case where the cables are connected in a straight line or at an arbitrary angle.

[Effect of the invention]

In the connection part of the flat cable according to the present invention, an insulating plate is provided inside the protective cover as an insulating reinforcing layer at the bolt connection part, so that the mechanical strength against external pressure of the connection part is improved and the insulation The electrical characteristics of the connection part are also very good.
