Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a heat seal connector applied to electrical connections between terminals of electronic components.

[Conventional technology]

Conventional heat seal connector (hereinafter referred to as connector)
1, as shown in FIG. A large number of conductive wires 3 are formed at the same pitch as the conductive wires 5 of the mating terminal 4 of the connecting T-beam, and both 3.5 are in contact with each other (hereinafter referred to as alignment).
In this method, electrical connections were made by heating and press-bonding (Japanese Unexamined Patent Publication No. 59-207686, etc.).

[Problem to be solved by the invention]

The above-mentioned connector 1 is thermally compressed with a heat block after aligning the conductive wire 3 with the conductive wire 5 of the mating terminal 4 and fixing it temporarily, but since the connector 1 itself is warped and flexed, The alignment described above becomes difficult, and it is difficult to automate the alignment of special numbers.

For this reason, alignment is often performed manually using a microscope or the like, but this requires skill and hinders productivity, so a solution to this problem has been an issue.

In view of the above-mentioned problems with the prior art, the purpose of the invention is to make alignment with the other terminal easy and to enable automation.
One thing is to provide a rubbing connector.

[Means to solve the problem]

The above purpose is to form an insulating and flexible resin sheet with a large number of conductive wires attached thereto, and to heat and press the conductive wires of the other terminal to electrically connect the two. In the heat seal connector, this is achieved by forming the arrangement pitch of the conductive wires of the connector more densely than the arrangement pitch of the conductive wires of the mating terminal.

[Effect]

By the above means, the conductive wire of the mating terminal always overlaps with any of the conductive wire of the heat connector of the present invention.
There is no special need for alignment between the two, and the electrical connection between the two can be easily made.

〔Example〕 Hereinafter, one embodiment of the present invention will be explained with reference to FIG.

In the same figure, 6 is a connector according to the present invention, for example,
A large number of conductive wires 8 made of a conductive material such as carbon, copper, aluminum, gold, etc. are formed by adhering to an insulating and flexible resin sheet 7 such as a polyester film or a polyimide film.

The present invention is characterized in that the arrangement pitch of the conductive wires 8 is set to be smaller than the arrangement pitch of the conductive wires 5 of the other terminal 4 that is electrically connected thereto. .

For example, if the pitch of the conductive wires 8 of the uninvented connector 6 is formed to be less than the pitch of the conductive wires 5 of the mating terminal 4, the conductive wires of the mating terminal 4 can be formed without any particular alignment between the two. One of the strips 5 (in contrast, since a plurality of conductive wire strips 8 of the connector 6 of the present invention can be brought into contact with each other,
Easy to make physical connections.

Therefore, in the terminals of ordinary electronic components, the pitch of the conductive wires is often 200 to 800 μm and 8 degrees, so the uninvented connector that connects these wires has a pitch of the conductive wires of about 50 to 200 μm or less. It is fine as long as it is something.

The uninvented connector can be widely applied to electrical connections between liquid crystal display elements and their drive circuits, as well as electrical connections between other internal components.

〔Effect of the invention〕

As explained above, according to the present invention, the electrical connection between the connector and the mating terminal is easily made, which is effective in improving productivity.

Furthermore, since it is easy to automate the connection, it is possible to speed up the connection and improve productivity.
