[0002]

2. Description of the Related Art FIG. 3 is a perspective view showing the structure of a main part of a conventional example in which a cable provided on an electronic circuit package is held at a predetermined position by a cable supporting device. In FIG. 3, a cable 53 is wired in a predetermined position via a cable support 52 in an electronic circuit package 51 in this circuit device.

More specifically, the electronic circuit package 5
1 has a plurality of fixing holes 54 penetrating the upper and lower surfaces, and a wiring pattern 55 is provided so as to avoid these fixing holes 54.

[0004] The cable support 52 integrally includes a cable holding portion 52a formed in a rectangular frame shape and a locking piece portion 52b extending downward from the lower surface of the cable holding portion 52a. It has the structure which was possessed. Also,
Locking claws 56 are provided on the left and right sides at the tip of the locking piece 52b, respectively, to form a substantially anchor. Further, a notch 57 is formed on the upper surface of the cable holding portion 52a at an inclination of about 45 degrees with respect to the direction in which the cable 53 is passed.
7, so that the cable 53 can be passed through the cable holding portion 52a. Therefore, in the cable support 52, when the cable 53 is removed from the inside of the cable holding portion 52a without being pulled out from the front-rear direction, the cable 53 cannot be removed without bending the cable 53 again so as to match the notch 57, As a result, the cable 53 does not easily come off the cable support 52.

In this structure, the cable 53
When the cable 53 is mounted on the electronic circuit package 51, the cable 53 is first connected to the cable support 5 through the notch 57.

In this attachment work, a procedure may be adopted in which the cable support 52 is attached to the fixing hole 54 of the electronic circuit package 51 in advance, and thereafter the cable support 52 is attached.

[0006]

However, in the above-described cable supporting structure in the conventional circuit device, the locking piece 52b is formed integrally with the cable holding section 52a by resin molding or the like. The shape becomes larger.
For this reason, it is necessary to increase the inner diameter on the side of the fixing hole 54 for receiving the locking piece 52b, and the wiring pattern 55 must also be formed so as to avoid the fixing hole 54 having a large diameter. There is a problem that the number of wirings is limited and high-density wiring is restricted. Further, a structure is adopted in which the locking piece 52b is inserted into the fixing hole 54, and the locking claw 56 is engaged and held on the back surface side. For this reason, in the case of a resin molding material, if the mounting circuit components are assembled before the solder dip, the engaging claws 56 may be thermally deformed and the engagement may become unstable.
After mounting the mounted circuit components, it is necessary to attach the cable support 52 and to route the cable 53, and there is a problem that the assembly is restricted.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to reduce the number of wirings by reducing the number of mounting holes required for mounting a cable, and to limit the number of wirings. It is an object of the present invention to provide a cable supporting device and a cable supporting method which make it difficult to obtain a degree of freedom in an assembling procedure.

And the cable support is rotatably attached to the fixing member, and the cable is disposed on the electronic circuit package via the cable support.

[0010]

According to this, since the fixing member for fixing the cable support to the electronic circuit package is formed as a separate member, for example, the cable support is made of a resin material, and the fixing member is made of a metal material having high strength. It can be structured to be fixed with the like. Thus, the outer diameter of the fixing member and the inner diameter of the fixing hole into which the fixing member is inserted can be reduced to increase the number of wires.

Further, in the case where the fixing member is press-fitted and fixed in the through-hole, it is sufficient to simply press-fit, so that the assembling work by the automatic machine becomes possible. Further, the cable support can be configured to rotate around the fixing member as a fulcrum. When the cable support is configured to rotate, the cable support can be oriented in an easy-to-assemble direction when assembling the cable.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing a main structure of a circuit device shown as one embodiment of the present invention. In FIG.
In an electronic circuit package 1 in this circuit device, a cable 10 is wired at a predetermined position via a cable support 2 and a fixing member 3.

More specifically, the electronic circuit package 1
Is provided with a plurality of through holes 4 penetrating the upper and lower surfaces, and a wiring pattern 6 is provided so as to avoid these through holes 4. Here, the through-hole 4 is, for example, the electronic circuit package 1
A through hole is formed in the upper part, and the inner wall and the peripheral edge of the hole are formed by applying a solder plating.

As shown in FIG. 2, the fixing member 3 is made of a metal material which can be soldered to the through hole 4 and is formed in an elongated pin shape. The stop portion 3a is integrally formed. Here, the outer diameter of the fixing member 3 is formed to be substantially the same as the terminal of the electronic circuit component (IC) for insertion and mounting, and
A part 3b of the intermediate portion of the fixing member 3 is formed as a bulging portion. The bulged portion 3b is formed to have an outer diameter substantially equal to or slightly larger than the inner diameter of the through hole 4. The bulging portion 3b has the bulging portion 3
When b is press-fitted into the through-hole 4, an elongated hole 8 is provided so that the bulging portion 3b is elastically deformed inward to make it easy to escape.

The cable support 2 is formed in a rectangular frame shape with an insulating material such as a resin material, and has a structure in which the cable 10 can be penetrated and disposed inside. Also,
The lower surface of the cable support 2 is provided with a mounting hole 5 through which the main body of the fixing member 3 passes. The inner diameter of the mounting hole 5 is smaller than the outer diameter of the stopper 3a of the fixing member 3 and larger than the bulging portion 3b. Further, the cable 1 is provided on the upper surface of the cable support 2.
A notch 7 is formed with an inclination of about 45 degrees with respect to the direction in which the cable 10 passes through, so that the cable 10 can be passed through the notch 7 into the cable support 2. Has become. Therefore, also in this cable support 2, when the cable 10 is removed from the inside of the cable support 2 without being pulled out from the front-back direction,
The cable 10 cannot be removed unless it is bent again so as to coincide with the cutout 7, so that the cable 10 cannot be easily removed from the cable support 2. In addition, the cable support 2 thus configured
The other end of the fixing member 3 is mounted through the mounting hole 5 from the inside until the stopper 3a contacts the cable support 2 and is positioned, so that the fixing member 3 and the cable support 2 are integrated beforehand. It is handled in the state assembled in.

When the cable 10 is mounted on the electronic circuit package 1 in this structure, the other end 3c of the fixing member 3 integrated with the cable support 2 and protruding from the lower side of the cable support 2 Is inserted into the through hole 4 from the mounting surface (front surface) side of the electronic circuit package 1. Then, the inner wall of the through hole 4 and the bulging portion 3b of the fixing member 3 are press-fitted and temporarily fixed to such an extent that they do not easily fall off. Thereafter, soldering is performed from the opposite surface (back surface) of the mounting surface of the electronic circuit package 1, and the other end 3c of the fixing member 3 is formed.

In this case, if the solder is dipped together with another electronic circuit component for insertion mounting mounted on the electronic circuit package 1, the solder can be fixed at once. Here, as the through hole 4 to which the cable support 2 is to be attached, a through hole 4 which is vacant without an electronic circuit component for insertion and mounting is selected. After the required number of cable supports 2 are attached, the cables 10 are sequentially inserted into the respective cable supports 2 through the notches 7. Then, the cable 10 can be routed and held at a predetermined position of the electronic circuit package 1 by the cable supports 2.

Therefore, according to the structure of the present embodiment, the fixing member 3 for fixing the cable support 2 to the electronic circuit package 1 is made of a metal material having high strength. It has become possible to reduce the diameter and to fix the fixing member 3 by inserting the fixing member 3 into the through hole 4 of the electronic circuit package 1. For this reason, it is possible to attach the cable support 2 using the vacant through-hole 4 without mounting components, without preparing the position of the cable support 2 in advance when designing the electronic circuit package 1. In addition, since the diameter of the through hole 4 is small, the wiring pattern 6 formed on the electronic circuit package 1 can be reduced. As a result, it is possible to increase the number of wirings. In addition, there is no need to separately provide a fixing hole for inserting the fixing member 3 in the electronic circuit package 1. Further, the fixing member 3 is inserted into the through-hole 4, and the fixing member 3 can be fixed to the through-hole 4 in the same process as the usual process of solder-dipping the electronic circuit component for insertion. Further, the cable support 2 may be configured to rotate around the fixing member 3 as a fulcrum,
When assembling the cable 10, the cable support 2 can be oriented in a direction in which the cable 10 can be easily assembled.

In the above embodiment, the fixing member 3 is formed of a metal material, and the fixing member 3 is lightly pressed into the through hole 4 and temporarily fixed, and then fixed to the through hole 4 by soldering. Although the structure as described above is disclosed, the fixing member 3
The swelling of the swelling portion 3b is made slightly larger so that the swelling portion 3b is firmly pressed into the through-hole 4, and the soldering between the fixing member 3 and the through-hole 4 is omitted. It can be fixed by just fixing. As described above, when the structure in which the soldering between the fixing member 3 and the through hole 4 is omitted is employed, it is only necessary to press the fixing member 3 into the through hole 4.

[0018]

As described above, according to the present invention,
Since the fixing member for fixing the cable support to the electronic circuit package is formed as a separate member, for example, the cable support is fixed with a resin material, and the fixing member is fixed with a metal material or the like which can obtain strength. Structure. Thus, the outer diameter of the fixing member and the inner diameter of the fixing hole into which the fixing member is inserted can be reduced to increase the number of wires. Also, since the fixing member is attached to the through hole of the electronic circuit package, it is possible to use a vacant through hole without mounting components without preparing a position for attaching the cable support in advance when designing the electronic circuit package. Mounting can be performed, and the cost can be reduced. Furthermore, in the case where the fixing member is inserted into the through-hole and fixed by soldering, the fixing member can be fixed to the through-hole in the same process as the process of dipping a normal circuit component by soldering. Work becomes possible, and assembly costs can be reduced.
In the case where the fixing member is further press-fitted and fixed in the through-hole, it is sufficient to simply press-fit it, so that the assembling work by the automatic machine becomes possible, and the assembly cost can be reduced. Further, the cable support can be configured to rotate around a fixing member as a fulcrum. When assembling the cable, the cable support can be oriented with the cable support oriented in an easy-to-assemble direction, thereby improving workability. The effect can be expected.
