Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a connecting terminal alignment assembly used in a connector for press-connecting a multi-core flat cable.

Conventionally, the connecting terminal alignment assembly used in the above-mentioned connector has been proposed, for example, as seen in Japanese Patent Application Laid-open No. 56-501467, in which first the first terminal and the second terminal are extended in opposite directions to each other, and then the base of the first terminal is aligned. A connecting terminal is prepared in which the terminal and the base of the second terminal are connected in advance, and this connecting terminal is temporarily held in the first terminal by first temporarily holding the first terminal alignment insulating block on a separately molded second aligning insulating block. This first terminal is temporarily held in the
The first and second terminals were fitted into the terminal alignment insulating block, and the first and second terminals were pressed between the two blocks to form a connecting terminal assembly.

The above method has the disadvantage that it requires a plurality of parts and requires a large number of assembly steps.Also, since it involves assembling a plurality of parts, it is not possible to reduce the size of the connecting terminal alignment assembly. However, there are limits to the miniaturization of connectors, which also has the drawback of increasing costs.
