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 a resistor, a capacitor, a diode, and a fuse in a flat cable made of a conductive foil, as shown in FIG. It is common that the portion is connected to the conductor portion 3 of the flat cable 2 by soldering or the like, and both sides are molded and covered.

[0003] As a configuration in which a circuit element is interposed in a cable, Japanese Patent Application Laid-Open No. 60-158566 is known.

[0004]

However, this conventional method not only requires time and labor for assembling, but also when the circuit element 1 is replaced due to failure or the like, the circuit element 1 is fixed by molding or soldering. Is not easy to replace.

Further, in the above-mentioned Japanese Patent Application Laid-Open No. 60-158566, a circuit element connects and branches a plurality of conductors of a cable to each other, and inserts an element between a pair of conductors. Instead, the structure is extremely complicated.

An object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a circuit element mounting structure for a flat cable that allows a circuit element to be easily inserted and removed.

[0007]

According to the present invention, there is provided a flat cable circuit element mounting structure according to the present invention, wherein the circuit element is detachably mounted between conductors of the flat cable. A chip-shaped component having both end surfaces as connection ends, a pair of curved holding portions having a spring property for holding the both end surfaces of the circuit element, and locking for locking the circuit element. And a holder having a portion between the flat cables, a conductor portion of the flat cable is adhered along a surface of the both curved portions of the holding portion, and the circuit element is fitted between the conductor portions. It is characterized by being detachably locked by the locking portion.

[0008]

In the flat cable circuit element mounting structure having the above-described structure, the flat cable conductors are adhered along the surfaces of the holding portions on both sides of the holder, and the circuit elements are fitted between the conductors. , And is locked by the locking portion.

[0009]

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. A holder 12 made of an elastic member such as a synthetic resin is interposed in an intermediate portion of a flat cable 11. A flat cable 11 is provided on the upper part of the holder 12.
And a pair of holding portions 12a and 12b for holding the rectangular parallelepiped chip-shaped element 13 having the circuit elements built therein and the connection ends 13a and 13b at both ends. These adhesive portions 12a and 12b are bent downward and bent, and 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 for locking and fixing the chip-shaped element 13 is provided.

Conductor portions 11a and 11b from which insulating coatings of the flat cables 11 and 11 are peeled are adhered along the surfaces of the holding portions 12a and 12b of the holder 12, and a chip is provided between the conductor portions 11a and 11b. When the chip-shaped element 13 is press-fitted and locked on the locking portion 14, the connection end 13 of the chip-shaped element 13
a and 13b are sandwiched by the sandwiching portions 12a and 12b having spring properties via the conductors 11a and 11b, and good electrical contact is obtained.

In particular, the conductor 11 of the flat cable 11
Since the conductors a and 11b are very thin conductors, the conductors themselves cannot have elasticity. Therefore, the conductors 11a and 11b are attached to the separate elastic holding portions 12a and 12b. , As a whole, a conductor having spring properties.

The chip-like element 13 may be a single type in which one circuit element as shown in FIG. 1 is provided in parallel, or 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-like element 13 can be mounted by simply pushing the chip-like element 13 between the bonding parts 12a and 12b of the holder 12, and when the chip-like element 13 is to be removed, the locking part 14 is pushed open. What is necessary is just to pull out the chip-shaped element 13.

[0014]

As described above, in the flat cable circuit element mounting structure according to the present invention, the conductor 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 conductors. Then, the mounting is completed only by locking to the locking portion, and the circuit element can be easily attached and detached.
