Description

[Detailed description of the invention] [Technical field of the invention] The present invention relates to a fixture used for gripping a flat cable and fixing it to a fixed side, and in particular, to a fixing tool used for gripping a flat cable and fixing it to a fixed side. This invention relates to a flat cable fixing tool that is easy to hold and can securely hold the flat cable.

[Prior Art] Conventionally, as shown in FIG. 5, a fixing device for a flat cable of this type consists of bending a plastic plate 1 into two pieces so that a space is formed inside, and inserting a flat cable between them. There is generally known a device that grips a power cable (not shown) and has an adhesive layer 2 disposed on the lower surface so that it can be fixed to a fixed side (not shown) via the adhesive layer 2.

By the way, in this type of conventional fixture,
Since the gripping force for the flat cable is obtained from the elastic force of the plastic plate 1, that force is relatively weak, and there is a drawback that when a single flat cable is gripped, the flat cable tends to fall off.
Conventionally, the wall pressure of the plastic plate 1 is thickened to obtain sufficient gripping force, but when multiple flat cables are overlapped and held with a single fixture, the plastic plate 1 The disadvantage is that the tip of the cap does not open sufficiently, making it difficult to install.

Further, conventional fixing devices using plastic plates cannot be opened completely regardless of the wall pressure. For this reason, if it is necessary to screw the plastic plate 1 to the fixed side instead of the adhesive layer 2, there is a problem that screwing cannot be done unless the shape of the plastic plate 1 is changed.

A possible solution to this problem would be to use a soft metal plate instead of the plastic plate 1, but the gripping force of the flat cable would be extremely weak.
In addition, there is a risk of the cable being shot between the cable and the flat cable, so it cannot be put to practical use.

[Purpose of the invention] The present invention was developed in view of the current situation, and it is possible to obtain sufficient gripping force whether gripping a single flat cable or multiple flat cables, and also makes the work easier. Another object of the present invention is to provide a fixing tool for a flat cable that does not have the risk of being shot between the cable and the flat cable and can be easily screwed onto the fixed side.

[Summary of the invention] The invention consists of an insulating lower half member whose lower surface serves as a fixing surface to the fixed side, and a lower part whose proximal end is connected to the proximal end of the lower half member via a hinge so as to be freely openable and closable. an insulating upper half member that holds the flat cable between the two half members; and a metallic upper half member that is removably attached to both of the members from their proximal ends and that presses and biases both members toward the closed side. a leaf spring, an insertion portion into which the leaf spring is inserted into an insertion hole provided at the base end of the lower half member toward the distal end; and a rising portion rising from the base end of the insertion portion; It consists of a holding part that is continuous with the upper end of this rising part and is arranged on the upper surface of the upper half member, and then the leaf spring is removed and the upper half member is fully opened, and the flat cable can be attached and the lower half member By making it easy to screw the flat cable onto the fixed side of the flat cable, and by sandwiching the flat cable between the two insulating members, there will be no problems with shorts between the flat cable and the flat cable. By attaching a flat cable and gripping the flat cable with the spring force of this leaf spring, sufficient gripping force can be obtained whether the number of flat cables is small or large.

As shown in FIG. 2, the leaf spring 13 configured in this manner is constructed by inserting the insertion portion 13a into the insertion hole 17, and
The rising portion 13b is raised along the rising portion 11b and the falling portion 12b of the base ends of both members 11 and 12, and the presser portion 13c is placed on the upper surface of the base end of the face plate portion 12a of the upper half member 12. Part 1
1 and 12, and is adapted to constantly press and bias both members 11 and 12 toward the closed side. At this time, the concave locking part 18 at the tip of the insertion part 13a is snap-locked to the convex engaging part 20 provided in the insertion hole 17, as will be explained in detail later, and the convex locking part 18 at the tip of the holding part 13c The shaped locking portion 19 is attached to the upper half member 12.
The face plate part 12a is adapted to be snap-locked to a concave engaging part 21 provided on the upper surface of the face plate part 12a.

As shown in FIGS. 1 to 4, the insertion hole 17 is provided in the widthwise center of the proximal end surface of the base 11a in the shape of a square hole toward the distal end of the base 11a.
At the tip of the top surface, there is an insertion hole 1 as shown in Figure 4.
A convex engaging portion 20 is provided with which a concave locking portion 18 at the tip of the insertion portion 13a inserted into the inserting portion 7 is engaged with a snap. In addition, a leaf spring 13 is attached to both members 1 at the base end of the upper surface of the insertion hole 17, as shown by the chain line in FIG.

A convex retaining portion 22 is provided which temporarily locks the concave retaining portion 18 at the tip to prevent it from coming off.

In addition, the rising portion 1 at the base end of both the members 11 and 12
1b and the falling portion 12b, the rising portion 13b of the leaf spring 13 is provided as shown in FIGS. 1 and 3.
A groove 23 is provided in which the plate spring 13 is fitted, and a groove 23 is provided on the upper surface of the face plate portion 12a of the upper half member 12, as shown in FIGS. is provided. The groove 23, the protruding strip 24, and the insertion hole 17 ensure the mounting stability of the leaf spring 13 mounted on the base ends of both members 11 and 12, and the other conductor 13 is minimized, and the protruding strip 24 and insertion hole 17 make it easy to attach the leaf spring 13 to both members 11 and 12.

Next, the action will be explained.

In manufacturing, as shown in FIG. 1, first, the lower half member 11 and the upper half member 12 are integrally molded, including the hinge 15, etc. by molding of plastic material, and the leaf spring 1 is formed using a metal spring material.
Mold 3. And the base 11a of the lower half member 11
For example, a double-sided adhesive tape with a release paper is attached to the lower surface of the adhesive layer 14 having the release paper.

Next, the tip of the insertion portion 13a of the leaf spring 13 is slightly inserted into the insertion hole 17, and the tip of the holding portion 13c is pulled upward. In this state, the leaf spring 13 is pushed forward. As a result, as shown in FIG. 2, the leaf spring 13 is attached to the base end portions of both members 11 and 12, and both members 11 and 12 are urged toward the closing side.

When using the fixture 10 assembled in this manner, first the leaf spring 1 shown in solid line in FIG.
3 toward the proximal end, that is, to the right in FIG. Then, the concave locking part 18 and the convex locking part 19 at the tips of the insertion part 13a and the holding part 13c of the leaf spring 13 are connected to the convex engaging part 20 and the concave engaging part 2.
1, and the leaf spring 13 is gradually pulled out toward the proximal end. Finally, the retaining portion 13c is removed from the upper half member 12 as shown by the chain line in FIG. 2, and the leaf spring 13 is substantially removed from both members 11, 12. At this time, the insertion part 13a is set longer than the holding part 13c, and the insertion hole 1
Since a retaining portion 22 is provided at the base end of the upper surface of 7, even if the presser portion 13c comes off from the upper half member 12, the engagement between the concave locking portion 18 and the retaining portion 22 prevents the insertion portion 13a from being removed. This prevents the leaf spring 13 from coming out of the insertion hole 17.
Even when the leaf spring 1 is removed from 1 and 12, the leaf spring 1
3 and both members 11 and 12 are not completely separated.

After removing the leaf spring 13 in this way, the upper half member 12 is opened wide upwards, and both members 11, 12
Insert the required number of flat cables (not shown) between them. Then, the upper half member 12 is closed again, and the leaf spring 13 is attached to both members 11 and 12 by the reverse procedure described above. Then, both members 11 and 12 are urged toward the closing side by leaf spring 13, and a force for gripping the flat cable is generated in both members 11 and 12.

After gripping the flat cable in this way, the release paper on the lower surface of the base 11a of the lower half member 11 is removed, and the fixture 10 is adhered and fixed to the fixed side via the adhesive layer 15.

If for some reason it is necessary to remove the flat cable held by the fixture 10, pull the leaf spring 13 shown in solid line in FIG. 2 toward the proximal end. Then, as described above, the leaf spring 13 is gradually pulled out toward the proximal end, and finally, the leaf spring 13
The concave locking part 18 at the tip of the insertion part 13a is inserted into the insertion hole 1.
When the leaf spring 13 is engaged with the retaining portion 22 of 7.
is substantially removed from both members 11,12. Thereby, the upper half member 12 can be freely opened and closed with respect to the lower half member 11. Therefore, upper half member 1
2 and remove the flat cable from the fixture 10.

Since both members 11 and 12 that come into direct contact with the flat cable are made of an insulating material, there is no risk of them being shot between themselves and the flat cable. In addition, although the leaf spring 13 is exposed to the outside of its standing portion 13b and presser portion 13c, both members are in a state in which both walls of the groove 23 provided in 11 and 12 and the convex strip 24 are raised from both sides. Therefore, even if a conductor comes into contact with the outer surface of the fixture 10, there is very little risk that the conductor will come into contact with the side walls of the groove 23 and the protruding strip 24 and come into contact with the leaf spring 13, so it is safe.

Further, since the flat cable gripping force by both members 11 and 12 is made of the metal leaf spring 13, a sufficient gripping force can always be obtained regardless of the number of flat cables. The leaf spring 13 is detachable from both members 11 and 12, so when inserting the flat cable between the members 11 and 12, the upper half member 12 can be removed by removing the leaf spring 13. It opens sufficiently to facilitate insertion of the flat cable, and even when it is necessary to screw the fixture 10 to the fixed side, the screw hole is provided at a position that avoids the insertion hole 17 of the lower half member 11. This allows for easy screw fixing. Furthermore, when the leaf spring 13 is removed from both members 11 and 12, the leaf spring 13 is completely removed from both members 11 and 12.
Since it does not separate from the plate spring 13, reassembly is easy, and since the presser part 13c can be opened upward with the tip of the insertion part 13a hooked into the insertion hole 17, both sides of the leaf spring 13 can be easily reassembled. member 11,
12 is easy to install.

Although not specifically explained in the above embodiment, if the base end of the face plate portion 12a of the upper half member 12 is formed as a slope with a downward slope toward the base end, the removed leaf spring 13 can be simply pressed forward. It can be attached to both members 11 and 12, making the attachment work easier.

[Effects of the invention] As explained above, the present invention enables the insulating lower half member and the upper half member to be opened and closed using the base end hinge as a fulcrum, and both members can be substantially attached to and removed from the base end side. The gripping force for the flat cable is obtained by a metal leaf spring attached to the
Sufficient gripping force can always be obtained regardless of the number of flat cables. Further, since the upper half member can be opened sufficiently relative to the lower half member, it is easy to work and it is also easy to screw onto the fixed side.

In addition, the insertion part of the leaf spring is inserted into the insertion hole provided in the lower half member, so if you use this as a guide, it is easy to attach and detach to both members, and the state of attachment to both members is stabilized. can be done.

Further, since both insulating members contact the flat cable and the metal plate spring does not come into contact with the flat cable, there is no risk of the flat cable being shot between itself and the flat cable.
