Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat cable circuit element mounting structure for connecting a circuit element to a flat cable to form a circuit.

[0002]

2. Description of the Related Art Conventionally, when a circuit network is constructed by interposing circuit elements such as resistors, capacitors, diodes and fuses in a flat cable made of a conductor foil, as shown in FIG. It is general that the part is connected to the conductor part 3 of the flat cable 2 by soldering or the like, and both surfaces thereof are covered with a mold.

Further, Japanese Patent Laid-Open No. 60-158566 is known as a structure in which a circuit element is interposed in a cable.

[0004]

However, this conventional method is not only time-consuming for assembling, but when the circuit element 1 is replaced due to a defect or the like, the circuit element 1 is fixed by molding or soldering. It is not easy to replace it.

Further, in the above-mentioned Japanese Patent Laid-Open No. 158566/1985, a circuit element connects and branches a plurality of conductors of a cable to each other, and inserts the element between a pair of conductors. However, the structure is extremely complicated.

The object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a circuit element mounting structure for a flat cable in which circuit elements can be easily inserted and removed.

[0007]

A circuit element mounting structure for a flat cable according to the present invention for achieving the above-mentioned object is such that when the circuit element is mounted in a flat cable circuit, the circuit element is mounted on both ends of the circuit element. A holder having a chip-shaped component as a connection end, the holder having a pair of curved sandwiching portions having a spring property for sandwiching both ends of the circuit element and a retaining portion for retaining the circuit element is provided. Interposed between flat cables, the conductor portions of the flat cable are adhered along both curved surfaces of the sandwiching portion, the circuit element is fitted between the conductor portions, and is locked by the locking portion. It is characterized by doing.

[0008]

In the circuit element mounting structure of the flat cable having the above-described structure, the conductor portions of the flat cable are attached along the surfaces of the sandwiching portions on both sides of the holder, and the circuit elements are fitted between the conductor portions. , It is locked by the locking part.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is a perspective view and FIG. 2 is a cross-sectional view thereof, in which a holder 12 made of an elastic member such as synthetic resin is interposed in an intermediate portion of a flat cable 11. On top of this holder 12, the flat cable 11
Are provided with a pair of sandwiching portions 12a, 12b for sandwiching the rectangular parallelepiped chip-shaped element 13 having the circuit elements built-in and connecting ends 13a, 13b at both ends. These adhesive portions 12a and 12b are bent downward and bent to have a spring property. Also,
On both sides of the place where the chip-shaped element 13 of the holder 12 is fitted, a locking portion 14 having a claw portion for locking and fixing the chip-shaped element 13 is provided.

Conductor portions 11a and 11b, from which the insulating coating of the flat cables 11 and 11 has been peeled off, are adhered along the surfaces of the sandwiching portions 12a and 12b of the holder 12, and a chip is provided between these conductor portions 11a and 11b. When the chip-shaped element 13 is press-fitted and locked to the locking portion 14, the connecting end 13 of the chip-shaped element 13 is
The a and 13b are sandwiched by the sandwiching portions 12a and 12b having a spring property via the conductor portions 11a and 11b, and good electrical contact can be obtained.

In particular, the conductor portion 11 of the flat cable 11
Since a and 11b are very thin conductors, elasticity cannot be imparted to the conductors themselves. Therefore, the conductor parts 11a and 11b are attached to the separate elastic sandwiching parts 12a and 12b. The conductor part has spring properties as a whole.

The chip-shaped element 13 may be a single type in which one circuit element is provided in parallel as shown in FIG. 1, but a plurality of circuit elements such as resistors, capacitors, diodes and fuses as shown in FIG. It may be an integrated type arranged in parallel.
However, in the case of the integral type, the shape of the locking portion 14 in FIG. 1 is different.

In this embodiment, the chip-shaped element 13 can be mounted by simply pushing it between the adhesive portions 12a and 12b of the holder 12, and when removing the chip-shaped element 13, the locking portion 14 is expanded. The chip-shaped element 13 may be pulled out.

[0014]

As described above, in the flat cable circuit element mounting structure according to the present invention, the conductor portion of the flat cable is mounted along the upper surface of the holding portion of the holder, and the circuit element is fitted between the conductor portions. Then, the mounting is completed simply by locking the circuit element, and the circuit element can be easily attached and detached.
