Abstract

PURPOSE:To secure a proper current capacity of each conductor by connecting metal terminals by a number corresponding to the width of each conductor to each conductor at the terminal portion of a flat cable. CONSTITUTION:At the terminal portion of a flat cable 13 which comprises a plurality of flat conductors 11a-11e arranged in parallel to each other and covered with an insulting cover 12 and which is molded into the shape of a band, the insulating cover 12 is peeled off so that each flat conductor 11a-11e is exposed. Thickness of each flat conductor 11a-11e is constant but the conductors are different in width and arranged in parallel to each other, and one or plural long-plate-shaped metal terminals 14 are stuck to the exposed portions of these flat conductors 11a-11e by the ultrasonic welding method and the like. There is thus no necessity of pressing the conductors 11a-11e and a proper current capacity of each conductor 11a-11e is secured.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a flat cable connector provided at a terminal portion of a flat cable for connecting a flexible flat cable.

[Prior Art] Conventionally, a flat cable connector with a connector member inserted into a mating connector housing to be connected has been manufactured by peeling off the insulation coating at the terminal end of a flat cable and leaving the exposed conductor part as it is. Those used as connection terminals are known.

However, in the conventional flat cable connector mentioned above, the extremely thin conductor itself comes into contact with the connecting terminal of the mating connector, and this cannot withstand repeated insertion and removal, causing wear and deformation. This causes a problem in that the contact state becomes unstable and the current capacity of the contact portion cannot be ensured.

As an example of solving this problem, as shown in Fig. 3, in a flat cable 3 in which a plurality of flat conductors 1 are surrounded by insulation coating 2, the insulation coating 2 at the terminal part is peeled off and the flat conductors are arranged in parallel. A conceivable structure is to connect a metal terminal 4 to each terminal, and sandwich the periphery of this connection between insulating members 5 and 6 that serve as a housing.

Furthermore, in order to increase the versatility and production efficiency of such flat cable connectors, there is an increasing demand for establishing standards for specifications such as terminal spacing and terminal width. Flat cables have different current capacities for each conductor depending on their circuit configuration.
As shown in the figure, conductors 1a to 1e with different widths are often used.In this way, the width and spacing of each flat conductor 1a to 1e of the flat cable 3 are standardized. If the width W and the spacing d are larger than the width W and spacing d of .

[Problem to be solved by the invention] However, if the structure shown in FIG. 5 is used, the conductor 1
Since the current capacity is limited by the constriction part and the adhesive part of the metal terminal 4, there are problems in that the desired current does not flow and the circuit does not operate, and heat is generated in the constriction part and the adhesive part. In addition, the narrowing part will be molded and provided when manufacturing the flat cable 3, but not only will the process be more complicated than when it is not provided, but it will also be standardized at the tip of the cable 3 cut to the desired length. The disadvantage is that it is not possible to install a connector that is

An object of the present invention is to provide a cable that can be
It is an object of the present invention to provide a flat cable connector that can secure an appropriate current capacity of each conductor while having a terminal arrangement that conforms to a predetermined standard.

[Means for Solving the Problems J] In order to achieve the above object, in the flat cable connector according to the present invention, in the terminal portion of a flat cable having a plurality of flat conductors having different widths, the width of each of the conductors is The present invention is characterized in that a number of metal terminals corresponding to the number of metal terminals are connected to each of the conductors.

[Function] The flat cable connector with the above configuration connects each conductor with a number of metal terminals according to its width, eliminating the need to narrow down the conductors as in the conventional case, and ensuring that each conductor has an appropriate current capacity. is ensured.

[Example] The present invention will be explained in detail based on the example illustrated in FIGS. 1 and 2.

FIG. 1 is a plan view of the terminal portion of the flat cable connector according to the present invention to which metal terminals are connected.

A flat cable 13 is formed by arranging a plurality of flat conductors 11a-lie in parallel and covering them with an insulating sheath 12, and forming them into a strip.The insulating sheath 12 is peeled off at the end of the flat cable 13, and each flat conductor 11a-1ie is exposed. There is. Each flat conductor 1
Although the thickness of the flat conductors 1a-1ie is constant, they have different widths and are arranged in parallel, and these flat conductors 11a-1ie
One or more long plate-shaped metal terminals 14 are bonded to each exposed portion of the ie by a method such as ultrasonic welding.

Here, for example, as the metal terminals 14, continuous terminals arranged in advance at predetermined intervals as shown in FIG. 2 are used. The number of metal terminals 14 to be connected differs depending on the width of the conductors 11a to 11e. For example, two metal terminals 14 are connected by vc to a wide conductor 11, and one to a narrow conductor 11. metal terminals 14 are connected.

Further, a housing shown in FIG. 3, for example, is fitted into the connecting portion of this flat cable 13, and through rods 7 provided in the insulating member 6 are inserted into an appropriate number of through holes 15 provided in the insulating coating 12. Furthermore, the locking groove 8a of the insulating member 6,
The metal terminal 14 is engaged with 8b, and the metal terminal 14 and flat cable 13 are stably fixed.

In the embodiment, the metal terminal 14 is a flat-blade terminal for insertion, but a flat-blade terminal may be used as a receiving terminal.

C Effects of the Invention J As explained above, the flat cable connector according to the present invention can secure an appropriate current capacity for each conductor, so there is no risk of malfunction of the circuit due to heat generation or insufficient current. Since the terminal arrangement can be made in accordance with standard specifications, the versatility of products and component parts can be increased, and production efficiency can be expected to be improved.
