[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible connector for automatic mounting, and more particularly to improvement of a technique for connecting printed boards by a flexible cable in wiring in an electronic device.

[0002]

2. Description of the Related Art Conventionally, when connecting a printed circuit board with a flexible cable, an operator generally uses a hand or a trowel or the like to connect both ends of the cable 1 through joints 10 as shown in FIG. The terminal 3 was aligned with the pattern 7 on the printed circuit board 2 and positioned, and then soldered.

[0003]

However, this positioning and soldering are very difficult in terms of work because of the flexible cable, and require a lot of man-hours. Particularly, when the pitch between the patterns 7 is small (inevitably the pitch between the terminals 3 is also small), strict position accuracy is required. If the positioning is erroneous, an accident such as a short circuit easily occurs between the adjacent patterns 7, and the operational reliability of the entire electronic device is impaired. For these reasons, flexible connectors have conventionally been considered unsuitable for automatic mounting. Therefore, an object of the present invention is to provide a flexible connector capable of automatically mounting a flexible cable without impairing the operational reliability of the entire electronic device.

[0004]

According to the SUMMARY for the present invention consists of a flexible cable and insulator pair respectively retain these terminals conductive terminals provided at both ends for connection to the printed circuit board connector And said pair
The insulators are connected together with adhesive tape.
The cable and the
A flexible connector for automatic mounting is obtained, which is characterized in that a pair of insulators is kept in a fixed state . Further, according to the present invention, there is provided a connector comprising a flexible cable having conductive terminals at both ends for connection with a printed circuit board, and a pair of insulators respectively holding these terminals, the pair of insulators. Between
And the cap is rigidly connected to each other.
Fixing the cable and the insulator of the pair
A flexible connector compatible with automatic mounting is obtained.

[0005]

According to the above flexible connector, the cable and the insulator, that is, the entire connector is kept fixed by the tape or the cap during the automatic mounting work. After the automatic mounting is completed, if this tape or cap is removed from the connector, there will be no effect on the connection state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the present invention.
A pair of insulations holding the terminals 3 at both ends of the cable 1, respectively.
The vibrators 4 are integrally connected to each other by an adhesive tape 5.
I am doing . In this example, the cable 1 is in a state without slack, but it is also possible to connect the cable 1 in a state with slack as shown in FIGS. 2 and 3. That is, the length of the tape 5 can be freely selected according to the connected state. As can be seen from this, the tape 5 is acceptable.
Using a tape that is flexible but not very flexible,
Due to the rigidity of the loop 5, an integral connection between the insulators 4
It has gained. As a tape that satisfies this condition, for example, the plate thickness
Polyimide heat-resistant resin tape of 50 microns or more
It After the automatic mounting is completed, remove the tape 5 of the connector,
No effect is left on the connection status.

FIG. 4 and FIG. 5 show another embodiment of the present invention in which the terminals 3 at both ends of the cable 1 are respectively held.
There is flexibility between the pair of insulators 4 but there is a margin of flexibility.
They are connected together by a cap 6 which does not exist . This connected state is shown in FIG. 6 (A), and projections 9 are formed on both ends of the cap 6, and these projections 9 engage with the positioning holes 8 formed in the printed circuit board 2 at the time of connection. When the connection is completed, if the cap 6 is removed as shown in FIG. 6 (B), no protrusion remains on the back surface of the printed board 2. Even if the cap 6 is used as described above, it is needless to say that the cable 1 can be connected in a loosened state as shown in FIG. 3 in the case of the tape 5 by appropriately selecting the length. is there.

FIG. 7 shows examples of various connections according to the present invention. FIG. 7A shows an example of horizontal connection, in which the cable 1 is in a straight state. 7B and 7C show an example of vertical connection, in which the cable 1 is bent by approximately 90 degrees. 7 (D) and 7 (E) show an example of parallel connection.
Is curved approximately 180 degrees.

[0009]

As described above, according to the present invention,
Since the relative position between the cable and the insulator is temporarily fixed by the tape or the cap during the connecting work, the alignment with the printed circuit board can be easily performed. Therefore, even if a flexible cable is used, it becomes possible to introduce automatic mounting of the cable and the printed circuit board.
